Delrina will distribute free versions of WinComm LITE for Windows and the full-featured FreeComm, an on-line communications package for DOS that competes with Datastorm+s Procomm Plus for DOS, to more than 50,000 bulletin boards (BBS) in North America. The product license grants users free unrestricted use of the software to introduce them to Delrina+s full-featured products: WinComm PRO and Communications Suite. Delrina is offering special upgrade pricing from either FreeComm or WinComm LITE to WinComm PRO for only $49.95 ($65.95 Cdn) or to Communications Suite for $89.95 ($119.95 Cdn). Both WinComm LITE and FreeComm are on-line communications software packages that enable users to connect to on-line services (such as CompuServe and MCI Mail) and bulletin board systems. They provide users with the facility to upload and download files using Xmodem, Ymodem, Zmodem, and CompuServe B+ protocols, and include support for the most common terminal emulations (VT52/100, ANSI, TTY and CompuServe). While WinComm LITE does not include all the features and capabilities of the retail product, WinComm PRO, it sports the same icon based graphical user interface that has set the standard for ease-of-use in Windows communications packages. FreeComm for DOS, on the other hand, is the full-featured product akin to WinComm PRO, which Delrina is licensing to users for free. "We are very enthusiastic about the products we have developed and we believe that users will share in that excitement once they try our software," said Marc Camm, general manager, Desktop Communications business unit at Delrina. "This promotion is designed to give the on-line community a risk-free sample of what we+re doing with our communications software, and to raise the level of awareness that Delrina is a serious long term player committed to this market. We+re confident that users will find these products extremely useful, and will feel encouraged to upgrade to our full-featured Windows communications product WinComm PRO," added Camm. WinComm LITE and FreeComm will both be immediately available for download through CRS Online at (416) 213-6002 or (416) 213-6003. Delrina recently acquired CRS Online, and the launch of WinComm LITE and FreeComm is the first promotion it is doing through the bulletin board service. Over the next few days Delrina will also place copies of the programs on its technical support BBS at (416) 441-2752, and its forum on CompuServe (GO DELRINA). Through the CRS Online connection, however, Delrina expects copies of the software to reach thousands of other BBS+s within several days. Since both WinComm LITE and FreeComm will be distributed freely through the on-line community -- a fairly sophisticated and computer literate group -- Delrina will not provide free technical support, but will encourage users to upgrade to one of the Windows products (WinComm PRO or Communications Suite) for which free technical support is provided. Delrina does not plan to upgrade FreeComm for DOS with further DOS versions. Delrina Corporation designs, develops, markets and supports innovative PC software products and services in the fax, data and voice communica- tions, electronic forms, and consumer software markets. Founded in 1988, the Company is ranked in sales among the top fifteen software publishers in North America and is recognized as the worldwide leader in PC fax and forms. Delrina employs more than 600 people with offices in Toronto and Ottawa, Canada; San Jose, CA; Kirkland, WA; Washington, DC; Lexington, MA; the United Kingdom; France; and Germany.

Date: 16 Mar 1995 01:11:30 GMT Organization: University of Pennsylvania First, thanks to all who answered my scanner question. Now, for number two: I finally broke down and got that cell phone today, a Motorola Microtac 550. The idea is to throw it into the shoulder bag and have it when I need it; it's a walk-around phone, since I don't have a car. So, having signed the contract, I read in the manual, "there's a magnet in the phone, so don't expose for long periods of time to magnetic media." Off I go to the 800 number, to ask how strong the magnet is. Their first response: "duhhhh..." Second response: "I talked to the tech people. It's a small magnet, about a quarter inch long. It's there to close the flip. The width of the phone and battery is enough to block the field, but of course we can't be sure." So ... I'm assuming that I'm not the first person in the world to throw the MicroTac into a laptop bag. I'm wondering if anyone has any information about whether this is dangerous in practice? I'll be keeping the phone in a pocket on the other side from the laptop, of course.

MFS, an alternate dial-tone provider in New York City, has started a charitable program in which they provide voice mailboxes for homeless people. Quotes from some of the recipients indicate that they have found this an extremely valuable service: If you are looking for a job, not being able to give a phone number where you can be reached is a killer. Giving the phone number of the shelter where you are staying sounds great, but a call answered with "XYZ Shelter" pretty much kills your job prospects. At least for the people interviewed, the voice mailbox led to a job. [Given the atmosphere on the net: No one so far, least of all me, is suggesting that providing "lifeline voice mailboxes" should be a government program or a legal requirement. What MFS is doing is old-fashioned charity, and deserves nothing but praise.] Jerry ------------------------------ From: hw42276@vub.ac.be (DEDECKER TOM) Subject: Information Wanted About Telecommunications in China Date: 15 Mar 1995 14:32:50 GMT Organization: Brussels Free Universities (VUB/ULB), Belgium Hello, I am a student at the Free University of Brussels and I am writing a paper about telecommunication development in China.

At least some European countries choose DTMF as means to send Caller ID, rather than the U.S. standard of 1200 baud FSK. The advantage is that the DTMF coded Caller ID can be sent BEFORE the first ring. Thus the called party in those countries, unlike us, need not wait four more seconds for the Caller ID. The disadvantage is of course slower signaling speed, adequate for now but constraining if you want name and number. I have seen pizza parlor operators in the U.S. frustrated over having to wait for Caller ID before answering the phone or deal with crank calls. ------------------------------ From: jobachmann@aol.com (JOBACHMANN) Subject: Telephony Demand Estimates - Any Clues? Date: 15 Mar 1995 13:24:57 -0500 Organization: America Online, Inc. (1-800-827-6364) Reply-To: jobachmann@aol.com (JOBACHMANN) I am getting confused by the various demand estimates and suggestions I am reading. Take mobile/cellular/GSM services in high GDP counties: is the current Swedish statistic of 98 GSM subscribers per 1000 population the saturation point? Or is a full 80%, as BIS has suggested, which "is interested in wireless communication"? In lesser developed counties, both mobile and lines compete for the same market. China is generally described as a huge market, which over 15 companies/consortiums are currently addressing, so that the 1993 (e.g. Shanghai) penetration of 11 per 100 has gone to 25-plus per 100 now. The point that many future market estimate reports seem to miss is that the Asian targets 1) are currently being addressed and 2) will have competition from Beijing Marine Communications, Indosat, Inmarsat-P, etc etc, 3) are unstable, i.e. China and Indonesia could forbid certain foreign companies to operate within their borders. With this in mind, what will the real demand, both fulfilled and unfulfilled, will be like in 1998? I appreciate any thoughts, references or discussion on this.

My 207 Meg drive has been rendered obsolete by MS Office, while ten years ago, AppleWorks provided a mouse driven, integrated word processor, database and spreadsheet using only 10 Megs. Does anyone remember "disk cracker," guaranteed to copy a disk in ten seconds or less? J Butz AT&T-GCCS Service SW Development jbutz@hogpa.att.com [TELECOM Digest Editor's Note: Sure I remember the VIC-20! We owners of OSI (Ohio Scientific, Inc) models C-1-P used to laugh at the VIC-20 guys. Then when I got my Apple ][+ I would laugh at the guys with the Radio Shack TRS-80 machines. And none of us had the vaguest notion where all this would get us ... ... the first BBS in the *world* was here in Chicago in 1979, operated by Randy Seuss and Ward Christianson. I used it a lot, as did all of the few people who had a modem. 110 baud ... ... that modem cost me a couple hundred dollars. Then Hayes came out with their 300 baud Smart Modem. I still have it around here somewhere. About the same time Bill Blue was putting together a BBS called "People's Message System" for Apple computers. I was the 'sysop' for the Chicago Public Library BBS, a book/movie review and social commentary system for about a year, and in the process developed a BBS of my own called Lakeshore Modem Magazine which was a social commentary/ discussion system with calendars of events for classical music programs in the area. I first had a membership in Compuserve in 1980 *before* they had the 'CB Simulator' program, let alone three different machines for it to handle the overflow on weekends ... ... in those days CIS actually thought people would pay $9 per hour to read the news and weather reports and use the Grolier's Encyclopedia on line. Then a guy working for CIS said how about let's experiment with a product where users can chat on line with other users. Everyone laughed at him; thought him quite the fool. They said no one would be interested in anything like that; they call in here to do research in the encyclopedia and to get the latest news and market updates, and to send email to our other subscribers (what few of them there were). But he persisted, and they decided to try 'CB Simulator' on a trial basis for a few months, if only so they could prove him wrong. Remember, we were just coming out of the 'real' Citizens Band rage, and they thought the name would be fitting. In a few months they had 50-75 people on there at a time on weekends, and the software bugs were aplenty: a backup machine was available and when 'CB would crash' and dump the whole congregation rudely off line and back their local nodes, within seconds you'd see the mob come back in and go to the standby machine. Then anywhere from a minute to thirty minutes later someone would announce 'CB is back up' and everyone would vanish from the overflow machine. One night -- I guess 1983 or so -- I was on the overflow machine (it was a lot quieter there all the time, none of the constant paging and the 'are you m/f how old?' questions on the other side. Just three or four of us sitting there chatting ... all of a sudden all kinds of people writing messages we see flowing past on the screen; a look at the user log shows ten people where there had been just three a couple minutes earlier. Another pass of the user log, seconds later showed about twenty people there ... what's going on, one of us asked; where are all these people coming from? "Oh," says one of the newcomers, "CB crashed again; the third time today; everyone is probably logging on over here until it gets back up." In those days the main CB machine was divided into channels like now, but as it got more crowded all the 'adult' channels eventually were moved to the standby machine and yet a third machine was put in for standby purposes. Now the standby machine is actually used as an adult overflow: last weekend at one point there were over a *thousand* people in chat all at one time on the three machines, with the teens having about 60 users on their 'channel' and the gay people with about 70 users on their channel. Routinely the adult machine reaches its maximum capacity early on Friday night and stays maxed out until Sunday night, with the late-comers going to the overflow machine. From Compuserve CB came all the imitators, the America OnLine Chat Rooms, IRC and all the others. We thought we were really hot stuff back in 1980 ... with our Apples and our VIC-20s and our TRS-80's from Radio Shack, aka 'Trash 80'. Who could have imagined all this? So when was the last time *you* logged into Compuserve to use the encyclopedia?

Goodin) Subject: UCLA Short Course: "Fuzzy Logic, Chaos, and Neural Networks" Date: Thu, 16 Mar 1995 19:01:43 Organization: UCLA Extension On May 22-24, 1995, UCLA Extension will present the short course, "Fuzzy Logic, Chaos, and Neural Networks: Principles and Applications", on the UCLA campus in Los Angeles. The instructor is Harold Szu, PhD, Research Physicist, Washington, DC., and Past President of International Neural Network Society (INNS). This course presents the principles and applications of several different but related disciplines -- neural networks, fuzzy logic, chaos -- in the context of pattern recognition, control of engineering tolerance imprecision, and the prediction of fluctuating time series. Since research into these areas has contributed to the understanding of human intelligence, researchers have dramatically enhanced their understanding of fuzzy neural systems and in fact may have discovered the "Rosetta stone" to decipher and unify these intelligence functions. For example, complex neurodynamic patterns may be understood and modelled by Artificial Neural Networks (ANN) governed by fixed-point attractor dynamics in terms of a Hebbian learning matrix among bifurcated neurons. Each node generates a low-dimensional bifurcation cascade towards the chaos but together they form collective ambiguous outputs; e.g., a fuzzy set called the Fuzzy Membership Function (FMF). This feature becomes particularly powerful for real-world applications in signal processing, pattern recognition and/or prediction/control. The course delineates the difference between the classical sigmoidal squash function of the typical neuron threshold logic and the new N-shaped sigmoidal function having a "piecewise negative logic" that can generate a Feigenbaum cascade of bifurcation outputs of which the overall envelope is postulated to be the triangle FMF. The course also discusses applications of chaos and collective chaos for spatio-temporal information processing that has been embedded through an ANN bifurcation cascade of those collective chaotic outputs generated from piecewise negative logic neurons. These chaotic outputs learn the FMF triangle-shape with a different degree of fuzziness as defined by the scaling function of the multiresolution analysis (MRA) used often in wavelet transforms. Another advantage of this methodology is information processing in a synthetic nonlinear dynamical environment. For example, nonlinear ocean waves can be efficiently analyzed by nonlinear soliton dynamics, rather than traditional Fourier series. Implementation techniques in chaos ANN chips are given. The course covers essential ANN learning theory and the elementary mathematics of chaos such as the bifurcation cascade route to chaos and the rudimentary Fuzzy Logic (FL) for those interdisciplinary participants with only basic knowledge of the subject areas. Various applications in chaos, fuzzy logic, and neural net learning are illustrated in terms of spatiotemporal information processing, such as: --Signal/image de-noise --Control device/machine chaos --Communication coding --Chaotic heart and biomedical applications.

To my considerable surprise given previously available information, I've learned from the data folks at GTE California that widespread ISDN implementation in their GTD-5 service areas will be rolling out this year. This is surprising since previously I had been led to believe that not only would ISDN service not be supported directly through GTD-5 switches, but that no plans for backhauling ISDN into those areas had been made. Apparently, this has all changed. For example, parts of the West Los Angeles area served by GTD-5 switches are slated for ISDN on 9/1, including remote RSUs served by those switches. There seems to be a general (no pun intended) plan to widely provide ISDN in those areas through what GTE is calling "overlays". I also obtained the rate information. While I don't have the numbers here with me, it appears that ISDN will be between two and three times more expensive per month (though a similar cost to install) for GTE customers than for area Pacific Bell customers. *Roughly*, the monthly charges would seem to be in the $40-$50 range if the customer is within 14K feet of the CO, plus another $22/mo or so if past that distance (for additional equipment). I'm not sure if the interstate line access charge is included in those numbers or not. There is a small differential (about $5/mo) between residential and business ISDN monthly rates. Business ISDN calls would be charged at conventional rates for local calls (all are measured), while residential ISDN (apparently) will incur no charge for local calls. All this is based on what I learned from GTE over the last few days, and of course may be subject to change. Interested L.A. area GTE customers should call the main business office number and ask for the "Huntington Beach Data Desk". Asking the front line people about ISDN is likely to not be particularly fruitful, to say the least. --Lauren-- ------------------------------ From: Morten Haugen <100115.1641@CompuServe.COM> Subject: Wireless, Extra Phone Outlets Date: 17 Mar 1995 08:38:51 GMT Organization: WM-data Communication A/S I saw an advertisement in CompuServe magazine for General Electric, which described some equipment (a sender and a receiever) for wireless, extra phone outlets.

Congress gives the Corporation for Public Broadcasting (CPB) $300 million per year, not the relatively paltry $147 million cited above. And that probably measures only the direct subsidy. There's indirect subsidies and grants that go to local stations and other organizations, for example, and some of these funds end up back in CPB's pocket; the real number could be as high as $500 million per year. There's also the license fees from sales of program-related merchandise (e.g., $200 million per year for Sesame Street and $500 million per year for Barney). The CPB has just decided to demand a percentage of those fees (I wonder what made them do that?). The problem with public broadcasting really isn't so much *content* as it is *attitude*. Much of its entertainment and education programming would have little trouble finding sponsors in the private sector. Even some of its better propaganda, umm, opinion, programs would do okay. However, most of the public broadcasting money is controlled by a small elitist clique with narrow interests. These are the people who gave $20 million to one station in New York where the executives draw salaries of $200-400 thousand per year. You know the type, they wrap themselves in a cloak of public service while collecting taxpayer money and begging the public for contributions. And then there's the Children's Television Workshop (home of Big Bird et al.) who pays salaries of $400-600 thousand per year. Considering the fact that 75% of public broadcasting money is spent on overhead, not content, is it such a good deal? There are, and will increasingly be, all kinds of alternatives to public broadcasting. It's an industrial age solution to an information age problem. I'll let someone else address Steve's apparent dislike for military marching bands, although I wonder: is it the "military" part or the "marching band" part he dislikes so much? Judging by the fact that he doesn't think Morning Edition is "left-leaning" (see below), I think I know the answer. Have a Good Day.

Yes, given their current enormous popularity, the bird and the dinosaur would certainly survive in some form. BUT, without the seed money provided by the government's subsidy, would they ever have come to exist in the first place? Would Ken Burns have been able to make the Civil War series? Etc.? Also, you miss the difference between commercial TV using programming to hook kids into wanting products, vs. PBS using appeals during programming to insure continuation of that programming, as well as being able to product new programming. It's a sad indicatin of our cynicism that many people can't imagine anything but a pure profit motive, that they can't imagine doing something (and paying for it) because it's a good thing for other people and the society they live in.

If you think you could spend your money better than PBS and NPR, contact your local congressman and ask him to cut tax money to CPB.

There was a large uproar a few years ago when East Hampton Long Island (home of the beautiful people) introduced a new exchange. I believe the old one was 267 and the new ones are 324 and 329 (in the 516 NPA). (I may have that reversed). The point is, though, that people who for some reason had to be moved to the new exchange were demanding to retain their old numbers so that they wouldn't be looked down upon as 'newbies'. There were those people that DEMANDED to be in the old exchange for the same reason (even though there are only 10,000 possible slots available and East Enders tend to have more than one number assigned for a variety of reasons. Stan [TELECOM Digest Editor's Note: I am reminded of the staff announcer on radio station WFMT, a local joke here which refers to itself as Chicago's Fine Arts Station who for *years* after the switch to all number dialing refused to go along with it and continued to give out phone numbers by their original exchange name. Advertising copy from sponsors would include a seven digit phone number and he would read it as exchange name plus five digits. Given that most people have long since forgotten about the exchange names, many listeners did not know what phone number to call, and the sponsors beefed about it. He kept on doing it anyway. Now and again a telephone number has to be recited over the air which is a 'new' exchange and has no 'old name' translation. I suspect it annoys him greatly.

I can pick up the phone in my Southwestern Bell service area and dial 713NXXXXXX and be connected, as long as the number being dialed is also in SWB's service area. Notice no "1+". When I try 713-534-0212 (the local time and temperature number, provided by GTE in their service area) I get a GTE intercept recording that my call could not be completed as dialed. If I dial it as seven digits, it goes through. If I dial 1-713-534-0212, I get SWB's intercept recording that it is not necessary to dial 1 or 0. If I go to my office in GTE's service area and try to dial 713-NXXXXXX I get an intercept, as with 1-713-NXXXXXX. Not that it surprises me (given GTE's track record) but it seems they are ignoring SWB and preventing their (GTE's) customers from calling legitimate numbers. For many, many years they had SWB's business office and repair numbers blocked (until SWB changed the numbers!) so I couldn't call from my office in GTEland to check on the status of my SWB orders and/or repairs. As if that will somehow convince me to give up SWB and move exclusively to GTE's area! It truly amazes me that GTE buys the latest in digital switches, has fiber running all over the place, etc. but chooses to have the lousiest customer service in the world.

I'd like to urge readers to think carefully before accepting her propaganda. What we have here is an attempt by some of the big players to get the government to help them do their marketing -- and, as is often the case, they are using reasonable-sounding arguments to try to get "grass roots" support. The law has traditionally recognized three kinds of property: real property (originally, just land), "tangible" property (most physical things), and "created" property (often called "intellectual property"). Of the three, tangible property is the easiest to understand. We all know what it means to own, say, a chair. The extent of the owner's rights in that chair are pretty clear to all of us. The government simply provides mechanisms for protecting those rights; the rights are inherent. Real property is more complex. For example, mineral rights can be separated off from the underlying property; zoning regulations may limit what you can do with land you own; and so on. But that's not relevent here. Intellectual property is the most subtle. Unlike the other kinds or property, it can exist only to the degree that government protects it. You can, at worst, arm yourself and keep people from walking off with your tangible property; but as a practical matter, you can't personally prevent someone from copying your copyrighted material. The US Constitution explicitly gives Congress the power "To promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries", a power it has exercised through the creation of patents and copyright. Congress isn't given the power to protect tangible or real property -- it doesn't have to be, since ownership of such property was and is viewed as an inherent right. Trademarks are a separate example, with a distinct history that probably goes back to European guilds (and come into US law mainly through state laws). In all cases, the government creates intellectual property rights for the common good of the citizenry, not exclusively for the individual who might claim that right. Because of this, the rights are carefully defined and deliberately limited. The Constitution itself says that patents and copyrights should be for a limited time, for example; the recent Lamachia case centered on the issue of whether copyright violation was theft in the legal sense (it isn't). Trademarks are also restricted. You can only create a trademark by using it in trade, for example -- you can't tie up a possibly-useful trademark for years in the US (though recent changes in the law have allowed some short-term reservations), as you can in some other legal systems. You can't prevent someone from using your trademark except "in trade": Lawyers for Coca Cola periodically write to magazine editors complaining about articles that refer to "Coke" generically. Coca Cola would prefer that the magazines indicate that this is a trademark, but there is nothing, legally, they can do to require it. As a general rule, the more "meaningful" a trademark is, the weaker the trademark's holders rights are. No one can trademark the work "book" to refer to printed matter -- though Microsoft, a very aggressive litigator which is pushing the law in this area, has asserted a claim on "Bookshelf" to refer to CD-ROM's containing collections of printed matter. While Microsoft may be able to control the word "Bookshelf" for CD-ROM's, they can't prevent Radio Shack from selling "bookshelf" speaker systems. "Exxon", on the other hand, is a term with no meaning, and Exxon can control it for essentially all uses in trade. Now consider our favorite example, 1-800-FLOWERS. Ms. Oppenheimer would first have us believe whoever is using that has a property right in it because they've spent money on advertising. Wrong. The Supreme Court not long ago rejected the "sweat of the brow" theory -- if I worked hard on it, the government must protect my rights -- in the one area of law where many had claimed it existed, copyright law. (This was the case that rejected copyright protection for white pages listings.) Will Ms. Oppenheimer claim a right to make a profit on 1-800-FLOWERS because she's spent money advertising the concept of ordering flowers by telephone? Sorry, anyone can enter the competition for that market; such "concepts" can't be protected. Ms. Oppenheimer of course would like to protect customers from "confusion". That's the most common excuse given for getting the government to kill your competitors. If a restaurant moves out of a location, does Ms. Oppenheimer believe no other restaurant should be allowed to move in there because customers might be "confused" and go to the new one based on advertising for the old? Bet let's even grant Ms. Oppenheimer the right to protect "1-800-FLOWERS". Is she happy? No; she wants more. She wants "011-800-FLOWERS" as well. And, when the new toll-free number space opens up, "1-888-FLOWERS" - and, later, "1-877-FLOWERS" and all the rest of the proposed expansion spaces. Where the legal tradition construes created property rights narrowly, she wants her rights construed as broadly as possible. How would she feel is some local store in a small town somewhere, which has had local number "FLOWERS" for the last fifty years, asserted earlier rights to "1-800-FLOWERS" and all the rest? This kind of thing has happened -- NBC, after spending hundreds of thousands of dollars on its new stylized "N" symbol, found to its chagrin that a PBS station in the midwest had been using the same symbol for years. (NBC bought the rights.) Or perhaps there's WERS radio has been advertising "356-WERS" as their dial-in number for years. How about their claim? What if they want "1-888-356WERS" to capitalize on the recognition *they've* built up over the years? I can see the argument for allowing the *full* "1-800-FLOWERS" as a trademark. It uniquely identifies a particular number across a whole national market; it can be used in trade; it's only partially meaningful. I reject the attempt on Ms. Oppenheimer's part to broaden the claim to cover every variant she sees being proposed. If she wants "011-800-FLOWERS", or "1-888-FLOWERS" as well, let her apply for and use those -- along with "1-800-FLOWARS" for those who can't spell. I see no reason why we as citizens should give her any special rights to those variations. By the way, precedent being formed today is against her arguments. MCI owns 1-800-ATTCALL, and directs callers who dial it in place of 1-800-CALLATT to MCI. ATT has cut a deal with a small business who's 800 number is a minor variation of 1-800-COLLECT to add a prompt that directs callers to ATT if it's a collect call they are interested in making. As I recall, someone else has 1-800-KOLLECT. [TELECOM Digest Editor's Note: Ms. Oppenheimer is with us again this weekend, with another message on this topic, and hers follows next.

This articles references a March 7th meeting; the next meeting is March 24th. Earl Barberly at the State Department can be faxed at 202 647-7407. Judith ----------------------- By John Hart Airlines, banks, car rental agencies, and other businesses in the toll-freephone business, would like one, worldwide toll-free number assigned to their companies. It would eliminate the myriad of numbers one has to maintain and advertise in Europe, for example, due to the complexity of the freephone service overseas. It seems a new proposal has been put forth to the International Telecommunications Union (ITU) called the Universal International Freephone Service (UIFS), which simply put, means a business can specify that when a freephone number is dialed in Europe, it rings in an office in the U.S. On the surface, this sounds like additional revenue for U.S. businesses, right? You're in Paris, and you want to re-book your flight, so you call 00-800-123-4567, and bingo, you've got your airline reservation desk in Tooele, Utah. It sounds like a good plan. Then why is Ben Levitan, who represents Aeronautical Radio, Inc. (ARINC), acting as the technical rep for the airline industry, an unhappy man? It seems, according to Mr. Levitan, that protecting existing U.S. freephone numbers is being ignored, and the idea that some company in Europe could easily grab the same digits as one of the airlines, is causing him headaches. Sure the Europeans must dial 00-800 plus seven digits, but the next seven digits may be the same as an existing airline, or a car rental agency, or any business with freephone service, or it may not. Of course, if you don't sign up for UIFS service, you're kissing off any possibility of ever getting your seven digits protected in Europe. But then, if you do sign up for UIFS service, you stand a good chance of not getting the same seven digits. The ITU says there is no guarantee even if you do sign up, you will get the same 800 number outside the U.S. The ITU has in mind a quick 30-day window where everyone faxes an application. Get real. Do the math. If every one of the four to five million U.S. businesses that want to keep their valuable toll-free numbers protected from ambitious European businesses, starts faxing, 24-hours a day, for 30-days, that's only 30,000 faxes in a month! And you'd better read the fine print before you file an application for UIFS. It clearly states in paragraph (g) "subscribers have no legal or proprietary claim to any UIFS number." In other words, your friendly common carrier will want you to declare that you have no claim whatsoever to the number. Never mind the thousands of dollars invested in marketing, not to mention trademarks. ARINC has been working hard on behalf of all U.S. 800 number users -- for example, they gathered the impressive ranks of such users as American Express, EDS and the Ford Motor Company to draft and present the "Users' Statement of Principles Regarding Universal International Freephone Service -- but according to Mr. Levitan, the Chairman conducting the ITU Study Group II meeting last December wouldn't even allow the introduction of any new proposal, let alone a discussion. "The clear answer is two country codes," Mr. Levitan told me. "But the comeback from the common carriers is 'we have a scarcity of numbers'. If that is the case, then our proposal is a new seven-digit code, but they're in a big hurry and want this UIFS service online now," he said. "The assignor of country codes is the ITU in Geneva, and they just don't seem interested in the two country code idea, either." What's the reason for pushing this UIFS deal down your throats? Profit, plain and simple. The U.S. common carriers stand to make a ton of money on all UIFS calls. That's an increase of a ton they aren't making now. And they want to power this paperwork through without you raising your telephone receiver to question their motives and objectives. Hello? Anybody out there? There's a public open meeting this March 7 and 8, in the Bellcore offices, Washington, DC, to discuss the status of the U.S. part of the UIFS proposal. Then, the ITU Study Group II meets in April, Tokyo, to decide if the present baseline document -- the one all U.S. common carriers love -- is acceptable and should be blessed with what they refer to as "accelerated procedures." 163 ITU member countries must approve the document. Only one U.S. representative has the power to stop it. His name is Earl Barberly, U.S. State Department. He can vote "yes," "no," or "six weeks delay," come April.

As someone who has been in this business for just about the same amount of time, I have to differ somewhat with that view. For high-volume applications, T1 is the answer to prayers. Besides being able to carry twenty-four conversations on two copper pairs, it does so with perfect transmission quality. One mile or ten, if the circuit is functioning, the audio quality is identical either way. Additionally, splits can be made so that high speed data can be carried on the bandwidth unoccupied by DS0 channels. > In some cases also, the many thousands of 'tiny little wires' are > easier for the person on location to repair and maintain. Lose a T-1 > for whatever reason and bunches of lines go out; lose a single wire > and its not that big of a hassle to start tracing the problem and fix > it. Because of its alarm reporting systems and loopback capability, it is frequently unnecessary to even send someone out, unless physical equipment needs replacement. Yes, the loss of a T1 takes twenty-four lines out of service. Because of that, telco responds accordingly. Response committments are in minutes, not hours or days. Rather than have a trunk with an annoying ground or some crackling sounds linger for a couple of days, restoration of the T1 span is usually accomplished in an hour or so. Sophisticated equipment can pinpoint T1 trouble in seconds. > Even if your demarc is a mess -- and I have seen some *messy* ones > with nothing tagged, wires in a jumble, etc, you can still put your > sounder or noise maker on the wire where it terminates (at the modem, > or phone or whatever) then 'ring out the line' back to the demarc, > find it there by listening and repair, replace or remove it or > whatever. Ten lines or ten thousand lines, no matter. T1 requires none of this. Also, digitally delivered service is free from inadvertant difficulty from sloppy cable splicers. There is no worry about half-taps, bridge-taps, crossed connections, or even installers "borrowing" your dial tone. There is something very reassuring to know that your 1.54 MBS circuit goes directly to a digital port on the serving 5ESS. If there is a fault on a T1 circuit, it is instantly detected and alarms are issued. More and more service is going to be delivered digitally in the future, if not by the RBOCs, then by their competitors in the dial tone market. In the SF Bay Area, Pac*Bell falls all over itself to deliver dial tone via T1. One of my spans currently has only four active channels. Digital "last mile" transport is neater, cleaner, and superior in every way to the method developed in the 1800s. As a side note, Netcom's headquarters are in the building in which I have a client. Every last bit of service is delivered digitally from the AXminster office in Santa Clara. The last of the analog service was just turned off this month. Naturally, the line quality is perfect. This is to be contrasted with my client's analog circuits in the same building that actually required MTM buildout. They squeal just before dial tone acquisition, sound hollow, and are otherwise substandard. Without conditioning, the level is unusably low. Needless to say, we are seriously discussing digital entrance facilities. John Higdon | P.O.

Personally, I never thought I would find myself in the position of defending anything that NYNEX does ... however, look at what you are comparing. Flexpath is a DID trunk service.

Unfortunately the originator is a Verifone credit card terminal and only has a 1200 baud modem. It is not possible at this time to get a 2400 or faster.

PAT] I was in high school when "Electronics" ?? magazine ran the "TV-TYPWRITER" project. I salivated. Then, I think a few months later, an advertisement for the ALTAIR computer was run. Damned if the address of the company wasn't in my major home town of Albuquerque, NM. I took the bus to their office, a small dump near the fairgrounds off Central Avenue (RT66). They (both of them) were friendly, and pointed to a box with toggle switches, an 8008 (the 8080 was an upgrade!) and yes, 256 bytes (the K was NOT left out!). It was playing a crude rendition of "Fool on the Hill" into a nearby radio by using RF generated by the clocking of diferent instructions! Bill Gates had not yet flown in from Boston with his Basic on paper tape! I later met the former financial officer of the company (MITS) - he had quit a few months before the advertisement had run because "they had no money and he was tired of lying to suppliers". Their local bank (ANB) was going to shut them down, but the founders begged enough money to run the advertisement (very risky for the bank -- New Mexico was (is) not noted for Venture Capital!). They said the Post Office brought $100K (the K is correct, in this case) in orders in one day! They (the founders) cashed out later (I forget who bought them). The fin- ancial guy who quit early is still working 9-5 ... [TELECOM Digest Editor's Note: Ah yes, the Altair. I never had one myself but read about them. My first machine was the OSI-C1P. It had 4K (yes 4000, or more correctly 4096) bytes of memory. The 'Basic in RAM' took up about 700 bytes, leaving about 3300 bytes to program with, using Microsoft BASIC, aka "eginner's ll-purpose ymbolic nstruction ode" is what that meant. And you know what? You could run a whole bookkeeping system on it. That's how I first learned any programming at all. With such limited space of course, you crammed all those instructions in there as many to a line as you could get, remembering not to get trapped in the middle of a line with an 'if/then' thing that might keep you from getting to the end of the line ... Then one day the company announced a major improvement: they had a new chip which had 8K (yes, 8192) bytes of RAM. Wow ... what were we gonna do with all that extra space? Not only that, by installing this chip you could now use both UPPER and lower case; both would work. I sent away for the chip and spent a couple hours one evening removing the old one and soldering in the new one. My Apple ][+ had 48K, with slots where you could install various things including a 'language card', or an additional 16K of RAM if desired. I had that thing loaded -- every slot taken -- with the language card, a printer card, modem card, two disk controller cards to operate four floppy disk drives, and a clock card from the Thunderclock Company (remember them?) My thing was writing programs to do rather elegant art on the screen and music, which played through the speaker in the Apple which I replaced with a much larger speaker. I had all kinds of hardware mods on that thing also including a 'lower case adapter'. If you opened it up and looked in back by the slots, the bus had all these solder traces that had been cut and re-jumpered and whatever. Those machines were *so much fun*. Apple used Microsoft BASIC with a few minor changes and they sold their package under the name Applesoft BASIC. Along the way, I picked up a couple of the 'black apples'. Most were in cream/white colored cases, but at one point Apple had a special run they manufactured for the Bell and Howell Company, and those were in black cases with the Bell and Howell logo on the front along with the Apple logo; thus the nickname for them of 'black apples'. One day I had been invited to give a demonstration of my artwork to a computer class at the Lawson YMCA. I showed them a little program I had written called 'Bach Squares'; it drew boxes on the screen in various colors which would explode into larger and smaller boxes, etc, while the speaker played (or rather honked, in a nasal sounding way) portions of the Gigue Fugue of Johann Sebastian Bach. All the folks in this computer class had books on 'Basic Programming Style'; you know, the books that told you how to indent your loops, add a liberal quantity of REM statements and put each instruction on its own line, etc. "How did you make it draw those colorful boxes and play that music," they wanted to know. I told them, the first thing you do, you take all those books on BASIC programming style and dump 'em all in the trash! You can't program in the space of 4 or 8K and neatly indent all your loops and if/then's and document it all besides. You take that code and you cram it and shove it and squeeze it in. Not only that, I told them, (looking them squarely in the eye in a stern way) *real men know how to program in machine (6502) code* ... ... have you mastered the op-codes and operands yet? The book's author was also there that night, apparently trying to hawk his books on programming style and I thought he was going to hit me over the head with one of them. Such great little machines, the Apples. I ran my BBS on one for about three years. They named today 'St. Patrick's Day' in honor of me; I'm the one who drove all the snakes out of Usenet. Have a nice weekend, all.

I was interested in AT&T's 500 service. It is advertised as something that lets your calls follow you wherever you go. But, after some research, I wonder about that. AT&T boasts that you can have your calls follow you to any most any phone on the planet, and that a 500 number is useful because it is portable. My problem is that I need to be able to receive calls from outside the USA and have the calls find me or my cellphone or my office wherever I am. 500 service sounded like it was the thing to get. So, I had a friend in the UK call another friend's 500 number to see what would happen outside of the USA. Unfortunately, the call would not go through. This led me to wonder how the 500 database is set up. After numerous calls, someone at AT&T was finally able to tell me that overseas callers should use USA Direct.

PAT] ------------------------------ Date: Fri, 17 Mar 1995 15:51:05 PST From: Carol Garbacik Subject: Help Needed With PBX at Remote Location I'm a relative neophyte at telephony (other job duties as may become required), working for a Federal Gov't agency. A couple of years ago we were forced to install our own PABX (Mitel SX200 Digital). Our location includes several buildings relatively close to each other, and one remote location (about 5 miles away). At this time I am facing armed insurrection (not really, just a flurry of really nasty memos) from the folks at the remote location. The situation is this: *We are colocated on a University campus. *The University is the POP for telecom services, therefore: our lines are dropped off at the University's phone room, and shipped out to us via unconditioned house cable. Calls then run out over our house cable to our buildings. The quality is adequate. *The remote location's calls are processed by our PABX then sent out (again via University cable) to the local Telco via OPX lines to the remote location. At the remote location they have an old 1A2 system with six button phones. There is a lot of line loss on the lines to the remote location. We have added amplifiers which help to some degree, but have also resulted in 'clipping'. The local Telco (since we are Gov't) won't provide any advice. The folks are so upset out at the remote location that every time the system burps (like all are CO lines are busy), they throw a hissy fit. Can we do anything to improve the service to the remote location? What? Help! Please!

A couple of months ago the landlord in my building installed a DOOR KING brand apartment entry system. You dial in a code, the outside box rings the apartment you want. Inside that apartment, the phone rings, or there's a "call-waiting" style beep. We're supposed to hit "9" then to open the door. My problem is that there's no way to suppress the "call-waiting" beep. Apparently the thing is wired directly into my private phone line, and doesn't go through the central phone company switch. This is extremely annoying, as it causes my modem to hang up on a connection like this one. I've been learning a lot about the unix kill command, getting rid of those wayward processes after I log back on. Anyway, because this apartment entry box was wired directly into my private phone line, I've been told by various people that this is a violation of the law. Is this so? I never gave permission for anybody to do anything to my phone line -- certainly nothing disruptive like this. I'd appreciate serious replies. Thanks. gimonca@skypoint.com Minneapolis MN USA Last Call Junior >>> 612-861-7094 <<< A cyber-rumpus-room [TELECOM Digest Editor's Note: It was attached directly to the 'house pairs' on the apartment building side of the telco demarc. This means you can change your phone number -- or not have phone service at all from telco -- and as long as there is a phone instrument in your apartment the front door system will cause the phone to ring (or give the call waiting tone). If you are on a call when someone comes to the front door, then the system tests the line for a busy condition, puts the central office call on hold and lets you talk to the caller at the front door. They're not bad deals; I have been set up that way in the past at a place where I lived a few years ago. Our version was actually from Illinois Bell called Enterphone. It is not against the law for the simple reason the landlord owns the wiring inside your building. About the only way around this is to see whether or not you have a *second pair* coming to your apartment. In most newer constrcution, there will be two or three pairs to each apartment. If there is a second pair, then either ask telco to move your actual phone line to the second pair, or ask the person maintaining the front door system to move your front door intercom service to the second pair. In either event you will then need a second actual phone instrument (or a two line phone) to handle front door calls. I don't think when Enterphone (and its variants by whatever trade name) was developed, anyone gave any thought to ways of suspending the call waiting tone for lines handling modem communications. Using *70 will of course suspend call waiting from the telco; it won't do a thing where the front door is concerned. Sorry about that.

The box is has a serial din-8 interface for status, ring detect, control, dtmf equivalents (etc), and audio in/out (along with mic and speaker pass thrus) ports to hook into a unix box with mic and speaker. Full-duplex audio available thru the hardware, sampling done by the host platform. No unix software or driver. Product information available at 800-73-STARS. ===================================================================== The device you described is the model T311 manufactured by Teltone. It is a DTMF/RS-232C interface, and is a reliable unit. It's fairly cheap, at $399 retail. Unfortunately, I don't have the phone #, but you could try an old NAB directory, or the Bill Daniels guide. AMX also has the AXC-DTMF interface card, but unless you already have an AXCESS system, the T311 is the path of least resistance, from a hardware/software/greenware standpoint. Teltone, Electronic Equipment & Supplies, Kirkland, WA 800 426-3926 ===================================================================== The best device that I have seen/used that does this is a device called the Computerphone III made by Suncoast Systems, Inc. It is about the size of a standard external modem. It has exactly the the things you listed in your email. Plus it has its own programming language in 'C' (and maybe other languages) that lets you program it via application control. I used to use one as an answering machine for my Unix computer, messages where stored on my hard disk. Apparently the product has been around for a while. I understand J.C. Penney used to use them in their catalog department for computer controlling and accounting their phone calls. Suncoast Systems can be reached at: Suncoast Systems, Inc. 3100 McCormick St., Box 22 Pensacola, FL 32514 (904)478-6477 ===================================================================== I went with the Digital Storefront; it has some problems that I'm working through. Essentially it's audio connection to the computer is a microphone level and it is incompatible with my computer's microphone port. Since I have a line-level input, I'll simply buy a microphone to line-level black-box and use that. Right now my "software" consists of a shell script that echos characters to the serial port. Works great. I decided on the Digital Storefront since they were the only vendor to answer technical questions.

It sounds like this might be a very good application for a packet-switched network. ISDN may handle thisE nicely for much less than a T-1. This is from PacBell's ISDN User's Guide: "A signle B channel of ISDN can support hundreds of user X.25 connections to a bulliten board, information service, database, or transaction host system. And while user transmissions can originate through either dialed modem links or through permanent ISDN D-channel connections, a host system's permanent, fully digital B-channel link to the packet network totally eliminates the need for modems at the host site." You might also want to keep in mind that D-Channel packets have under 1 second setup time, whereas a modem takes upto 30 seconds to negotiate. Most ISDN phones have PAD (packet assembler-disassembler) built in. Rates in the Pacific Bell Service area for data packets are: .05 CENTS for transaction setup .005 CENTS per octet of data Steve cogorno@netcom.com ------------------------------ From: serviss@tazdevil.cig.mot.com (Gerald Serviss) Subject: Re: Using Live Radio With Automated Attendant Date: 17 Mar 1995 15:21:48 GMT Organization: Cellular Infrastructure Group, Motorola Ward Larkin wrote: > It's not that big a deal to use audio CD, or a tape deck, I simply > want to know what specific FCC regulations (if any) prohibit use of > live radio on telephony systems.

A number of places that I call, where there is radio on hold, seem to pick the news-radio or all-talk stations. I understood that the reason behind this was that if they picked a station with music, they would then owe royalties to the copyright holders of the music. > It's not that big a deal to use audio CD, or a tape deck, I simply > want to know what specific FCC regulations (if any) prohibit use of > live radio on telephony systems. I'm sure you would run into the same situation with CD or tape, unless you purchase something that includes the rights for this type of use. There are hold devices that play random musical tunes while on hold, boring. Have you heard that these music license folks have been going into places that play a radio in the background and demanding license fees? I believe in fairly compensating the artists but this seems a bit overboard. puma@netcom.com ------------------------------ From: pturner@netcom.com (Patton M Turner) Subject: Re: Using Live Radio With Automated Attendant Organization: NETCOM On-line Communication Services (408 261-4700 guest) Date: Sat, 18 Mar 1995 03:29:12 GMT adelante@sccsi.com (Ward Larkin) writes: > I'm fairly new to telephony, but I have installed a couple smaller > automated attendant, fax-on-demand, voice mail systems.

Never heard of this, but you may not retransmit audio w/o the radio stations OK. A payment to ASCAP/MBI may be required as well. Most everybody does it anyway.

I'm wondering how > true these claims may be, and how others manage to get this many lines They manage to get the lines by ordering them! Remembering my experiences in Pac Bell land, when we had 100+ lines coming in and growing, it seemed that T1s would be a better route. So I called them to chat about it, and they got all excited -- thought it was a great idea, sent over a couple of tech types to look around, talk the idea up and all. When I explored the cost "savings," it turned out that the cost for the T1 was *in addition to* the normal cost for 24 POTS lines! It went: "Let's see, the monthly cost for T1 is (I forget), plus each T1 carries 24 POTS lines at $21.80" (or so; I still forget, but it was the same as POTS via the tiny wires we both were trying to avoid). The bottom line was that I should write them a *much* larger check each month for the privilege of saving them money. When I pointed out that this didn't make any sense, they played the tape that goes "Our hands are tied ... PUC Tariff ... there's nothing we can do." It did no good to play my tape that goes "Let's see if I understand this: Your salaried employees craft a tariff, type it using machines you own, submit it for approval. Instead of saying there's nothing you can do, why don't you type it differently?" I'd expect your provider has walked this path also. If the pipe in from the street is full, it takes time (if not, it just takes an order). Here in GTE-land, we moved into a building that would was almost maxed out after we installed a bunch of lines. One day they showed up (we hadn't asked them; they hadn't asked us), dug a 180 foot trench, and installed 200 more pair in the building. "Just in case." (It's still lousy service) > (I keep urging them to co-locate, both for better avilability of lines > and for better quality on modem connections.) I don't believe this is something that you can force on them. It implies that they rent space to you, and that you have physical access to your equipment (within their boundaries). Neither is something that they are anxious to do.

This is a 30 day test kit for email (maybe) and news, in the US and Canada, under Windows. What is really included here is a crippleware demo version of the MKS mail and newsreader software for Windows. Arrangements have been made with The Rabbit Network Inc. for thirty days' free access through an "800" number. At the end of thirty days, the demo will stop working, but you can contact MKS and get an "upgrade" for fifty bucks more (sixty, in Canada), and contact Rabbit for a proper account. (Alternate arrangements have been made with Portal. This "30 days free" is valid for only the first five hours, and requires a credit card number for validation.) The book is basically documentation of the MKS software, although about a quarter of it is taken up with an extensive Internet provider list.

In aggregating the block A and B winning bids for each market, New Orleans was somehow skipped, with the result that it was listed twice, but both times at an extremely understated value. Below is a revised version of the list which corrects this error and makes some other changes: ========================================================================== Comparative Value of the MTAs ========================================================================== The following tabulation shows the comparative value of each MTA, calculated and ranked on the basis of dollars bid per pop. The winning bids on each of the two licenses in each MTA were combined, except in Washington, Los Angeles, and New York where only one license was auctioned due to the previous pioneer's preference grants. Each of those three markets is shown twice in the tabulation below, once including only the winning bid for the Block B (w/o pp), and once including both the Block B winning bid plus the Block A pioneer's preference revenue (w/pp).

Cartwright - ELF Subject: New Bell Atlantic Service From the {Washington Post} Friday, March 17, 1995: (all typos are mine) ***** Montgomery to Get Phone Message Service ***** Bell Atlantic's Residential 'T-Mail' Experiment is First in Country -------------------------------------------- By Mike Mills / Washington Post Staff Writer -------------------------------------------- Beginning next week, Montogomery County residents may notice something different when they pick up their telephones: three quick beeps before they hear a dial tone. It will mean that they have a "T-Mail" message waiting. "T-Mail" is a new service that Bell Atlantic Corp. is trying out among its 400,000 customers in the county, with plans to expand the service area-wide if it's popular. The first such residential service in the country, it is designed to let a community group distribute messages to members, or a daughter to get information to a parent who isn't home. Unlike Bell Atlantic's Answer Call voice mail service, T-mail does not take messages when people don't answer their phones. It's more like the voice mail that many offices now have. Callers in Montgomery County will be able to pick up their phones and dictate messages that Bell Atlantic computers will record and then send on to the phones of an individual or group of people who have the service. The phones will not ring to alert the recipient. Instead they will hear the beeps before the dial tone when the phone is picked up, or a light will blink (of the customers own newer models of telephones equipped with message lights). To retrieve messages, customers will dial a special number and enter their private passcode, and then listen to, delete or forward messages to others who have the service. T-mail will allow customers to leave a message for someone who's not home and doesn't have an answering machine. Or, the same message could go to a large number of people: A soccer coach could update team members on practice schedules or a teacher could notify parents about homework assignments. T-mail will be free from next Monday until May 30, after which customers will pay 25 cents for each message they send or copy. Listening to messages will remain free of charge. Customers who subscribe to Answer Call will pay 15 cents per message. The service is part of larger efforts by Bell Atlantic and other local phone companies to increase their revenue by making their networks "intelligent". They see services such as this as prime opportunities for new revenue from basic residential phone service, which is only marginally profitable. Bell Atlantic is also trying to enhance the value of it's own offerings as new competitors threaten to offer competing local phone service. Bell Atlantic officials say the service won't be a new opening for telemarketers. Junk-mail callers will be dissuaded from stuffing mail boxes with messages, they predict, because of per message cost and because mass messages can only be sent to as many as three groups of 25 recipients each. People who don't want the service can call 1-800-870-0000 to have it disconnected. The service also will further Bell Atlantics's efforts to take business away from the answering machine industry. Answer Call voice mail service already reaches 1.4 million residential customers, according to Bell Atlantic, more than any other U.S. local phone company. But nationwide, about 54 percent of U.S. telephone users still have an answering machine, or more than 125 million people, according to the Electronic Industries Association. ------------------------------- I posted this because in addition to being a "new" service, it hits on several topics discussed here of late. One is phones that detect stutter tone or some other message waiting data that lets the phone know there is a message (any bets only the RBOC's sell this little gem). And "Junk-mail callers will be dissuaded...", would you pay $60,000 dollars to reach 400,000 people? Not to mention that its **FREE** for the next ten weeks to the everyone including telemarketers! I grant you that it make take some doing but I'll bet some replacement window company, or credit card insurance marketer has already paid the overtime to cash in on the free advertising to all of Montgomery County. Plus I thought any phone number with seven zero's in it was worth mention. I'll try to keep you posted. If I'm not too busy listening to all my new T-Mail ... Chris Cartwright, Technical Engineer Mail dsc3cjc@imc220.med.navy.mil [TELECOM Digest Editor's Note: Please let us know your early experiences with this new service ... or is it a disservice? PAT] ------------------------------ From: telecom@eecs.nwu.edu (TELECOM Digest Editor) Subject: Cellular Fraud in the News Again Date: Mon, 20 Mar 1995 10:30:00 CST Over the weekend in the {Chicago Tribune} writer Kathy O'Malley offered an interesting article on cellular fraud, primarily discussing how phones are cloned and then abused. The thing which caught my eye, and which I discussed with her briefly on the phone Monday morning was her tossing around of the figures given to her by some industry people: $1.3 million per day in fraud; and that this represented four percent of the industry's annual traffic. By my calculations, 1.3 million per day comes to about $454 million per year, and that figure is four percent of what astronomical amount? I know we have had discussions on this here before and many of you contend losses due to fraud -- while a significant problem -- are substantially less that the dollar amounts quoted on a routine basis in the media and by industry representatives. Ms. O'Malley asked me, if $1.3 million per day is *not* correct, then what amount is correct or more realistic? I'd like to forward her some more accurate data if that is possible. Can anyone provide anything? She said to me she was prompted to write the article based on her own unfortunate experiences of being cloned twice in the past year. I told her I could easily see and understand her feelings, but that overstating the amount in question did not benefit anyone ... some of you here explained that to me the last time this topic came up. She is at the {Chicago Tribune}, 435 North Michigan Avenue, Chicago 60611 if you care to provide rebuttal, although it might be best if you send it to me and I will pass it along.

They seldom mention the necessity for learning cryptic one- to three-letter codes that indicate which of a bewildering variety of archival, compression, encoding, viewing, and other programs need to be brought to bear on a given file, in order to make it yield up its secrets. The promoters often stress that much of this stuff is free (or ridiculously cheap), but don't stress the fact that, for that very reason, most of what you need simply cannot be found at the local "Computers-R-Us". This slim volume is an excellent starter for newbies who want to begin downloading. The network cognoscenti will find nothing fresh here, but it is pitched exactly right for the newcomer. It covers the concepts of freeware and shareware (though not, interestingly, public domain); the basics of downloading; compression, archiving and encoding; media files; and some resources and filename explanations. The material is not exhaustive, but does cover the important points--including how to read version numbers. An included disk provides the basic archiving, compression, encoding and viewing tools that the Windows user will need to get started. There are a few points one might want to argue. (There is also a script font, used for headers, which is very difficult to read.) By and large, however, there is nothing to block the value of this work for the new user. For such a small book, the price might seem excessive. However, the fact that this book, and an hour or two of study, can get a neophyte online, would make it well worth the cost. copyright Robert M.

When Guttenberg "revolutionized" communication with the printing press an understanding emerged that things would be different. New communication would forever alter human interaction. When Marconi and radio transmission came along the same "revolutionary" mindset emerged. Finally and ultimately national governments would be held accountable for all their actions. Television, the last media/communication "revolution" re-inspired, albeit only fleetingly, the human belief in control of their personal intellectual destinies and re-invigorated the government watchdog mentality. We surf, now, on the most recent technologically induced media revolution but, nevertheless, allow it, even in its relative youth to go the path of humanities other communication "revolutions." Neil Postman talks of, Americans in particular, informing ourselves to death. Coinciding with that concept is the consuming ourselves into oblivion argument that I wish to describe. Often unbeknownst to ourselves we are constantly, both subtly and blatantly, force fed consumerism. In its dramatic form, television commercials are now as hyped, constructed, debated and created as detail oriented and cost (un) effective as feature films. TV commercial consumption and viewing is, personally, dramatically more entertaining/ dumbing than the actual programs they interrupt. One need only mention particular campaigns to fathom the country's familiarity with thirty second "buy something" commands that now pass as pure entertainment. The IBM nuns, the AT&T/MCI wars, "Where's the Beef," etc. Although the shows are by no means free from this consumptive mindset. Whether its the mind-boggling, seemingly constant cross promotion of television shows (In particular on the upstart Fox network programs) or the nonchalant product placement within your favorite show's star's apartment or hand, or the subtle programming differences that slide you from one program to another commercial free; We constantly have the "consume" command brow beaten into our minds. Every television millisecond is a command to buy something. Intertwined in PBS programs, live sports coverage, even Presidential address' complete with network logo in bottom right corner and pre/post, book-selling, anchor persons and analyst response is the "run out and charge something" message. So avoid your television. Kill your television! The escape and "freedom" is only minimal. Movie product placement, action figure sales, sequel contracts etc. promote constant consumption within the movie industry. The entertainment conglomerates, in general, have a strangle hold on all of our often unearned dollars. Freedom and the great communications "revolution" of the Internet is relative mini-seconds away from the same mind-numbing, content-guiding path of the almighty advertising dollar. Much needs to be said both in support of and against the publishing industries role in guiding the Internet. The atomized publishing industry of books, periodicals and newspapers seems to be "getting back at" or "standing tall in light of" the digital/digitized hype surrounding technological innovations such as the Internet which, often self-described, spell the decline and fall of the traditional written word and its format. One need only look at the shelf-space dedicated to computer how-to manuals in their favorite bookstore to get a grasp on the publishing industries success. Even Nicholas Negroponte's book "Being Digital" has entered the best sellers list. A new non-fiction is emerging from the computer how-to publishing market and it indicates a course for the Internet itself that needs addressing. In promoting the further stupefaction and status quoness of the race to digitize the planet, the infrastructure ownership, mainstreaming, non-technical understanding, user-friendly access learning usage curve and the ever growing plethora of related literature is focused on privatized, commercialized, consumer based and driven stupefacation. "How to make a million on the Internet," "Winning cyber-friends and influencing the non-cyber to buy your goods," the list of real and shockingly possible concepts for usage of the Internet in the public domain promoted by the atom publishing industry show nothing other than the same social ills that plague all current mediums. The Hacker, the one true friend of the common good on the Internet, is being lambasted, tracked down, arrested and eliminated from access in the name of some cyber justice that helps clear the way for the great revolution of key-stroke credit card purchases envisioned by the well funded, government supported, retail industry. Where the WWW and Internet could take human connectedness and communication is unimaginable. The course seems well laid out to take this revolution down the same path the worlds other technological driven communications revolts have gone: Into our consumer washed brain and out our overstrectched personal and national credit line.

A thought, with the world of business getting smaller, it seems to me a simple solution of providing a 'international country code' which could be used exclusively for world-based businesses. Written guarantees outlining the use of this new country code could be put into place that would/could satisfy both the telco's and customers. I've always felt (in concept) that the 800 number is a national business exchange. To try to place international restrictions against it interferes with national business interests. I do not necessarily apply this to US business interests but, the investments of businesses who have toll free numbers in any country. A 'toll-free' country code would open a new market for the telco's and provide a elegant solution to the corporations that have the need for these services. Surely, I'm not the only person who has thought of this. jim.wenzel@grapevine.lrk.ar.us The Ferret Bulletin Board System (501) 791-0124 North Little Rock, Arkansas Carrying RIME, Throbnet, UN'I, and Usenet ------------------------------ From: Rrivera@spin.com.mx (Rafael Rivera) Subject: Telephone Cost Research Date: 20 Mar 1995 03:10:43 GMT Organization: SERCOFIN I am doing a research on the cost/benefit of telecommunications with special focus on telephony.

Regardless, there are no such carrier costs. The FCC "found" that per-call blocking has "no significant additional SS7 costs" and should be free. Per-line blocking is clearly less expensive for the telco. The argument against per-line blocking is that it reduces the "value" of Caller ID to the callee, and therefore would reduce callee revenue to the telco. In other words, the concern is that people might actually use it. Which is my point. Needless to say, I am not impressed by this argument. ------------------------------ End of TELECOM Digest V15 #156 ****************************** Received: from delta.eecs.nwu.edu by MINTAKA.LCS.MIT.EDU id aa08900; 21 Mar 95 5:09 EST Received: by delta.eecs.nwu.edu (4.1/SMI-4.0-proxy) id AA23253; Mon, 20 Mar 95 23:10:15 CST Return-Path: Received: by delta.eecs.nwu.edu (4.1/SMI-4.0-proxy) id AA23246; Mon, 20 Mar 95 23:10:12 CST Date: Mon, 20 Mar 95 23:10:12 CST From: telecom@delta.eecs.nwu.edu (TELECOM Digest (Patrick Townson)) Message-Id: <9503210510.AA23246@delta.eecs.nwu.edu> To: telecom@eecs.nwu.edu Subject: TELECOM Digest V15 #157 TELECOM Digest Mon, 20 Mar 95 23:10:00 CST Volume 15 : Issue 157 Inside This Issue: Editor: Patrick A.

PAT] Cellular companies _are_ working on systems like that and in fact there are several already out there, most notably one called _Hotwatch_ by a former employeer of mine, Cellular Techinal Services of Seattle, Washington. However, this sort of usage-level monitoring requires real-time rating of calls and remote call delivery of roaming calls (this is important since most cloners are roamers), neither of which is trival or inexpensive. Believe it or not most calls are rated via batch tapes and not as they happen. This technology is available in some of the high-fraud markets now and will be available everywhere in the next few years but it's going to take a while. IMHO, I think it's funny that people with poor credit won't complain about failing to qualify for a new car loan but will complain because a cellular carrier won't take a risk that they'll skip after generating tens of thousands of dollars (retail, let's not start that argument again) worth of cellular service. A cell phone is no different than having a Visa card with a $10,000 limit so it's not surprising that they won't give them to just anyone. No insult intended towards college students but they should know how hard it is to get credit for anything.

Throughout the 1960's as BankAmericard (now it is known as VISA) first got established, and member banks signed up to offer it, they had to write off huge amounts of bad debt -- many millions of dollars annually -- due to poorly planned administration of their program and the virtual impossibility of holding users to pre-established limits. Credit limits in those days basically relied on the customer being on the 'honor system' although the customers were never told that for good reason. Everything was done on manual, paper tickets where the merchants were concerned, and these paper tickets would flood into the credit card processing office by the hundreds of thousands daily. It was only at either the 'cycle billing' (what went in the mail to the customer) or the 'interim billing' (an in-house report used by the collectors) that the credit card office got wise to someone over their limit. If you knew you were getting close to your limit and you went on a *big* one day shopping spree for instance, all those charge tickets would come crashing in at the same time, and if they missed the billing cutoff by even a day they'd sit in the vault until the next billing. 'Smart shoppers' knew just what day to shop if it was their intention to abuse that VISA, American Express or Diner's Club card. Naturally the office would see it and the card would be blacklisted in the next (weekly) issue of their 'bad cards list' that went out to the merchants. By then, the customer was way past any reasonable amount of debt. The credit card people finally got the idea of doing 'sales author- ization' where the merchants had to call in and get approval for the sale. There had to be a happy medium somewhere so the merchant was not inconven- ienced (they were still trying to sign up merchants to accept BankAmericard) and they did not want to annoy the card holders too much either, so they set 'floor limits' for sales. Amounts over that had to be called in for approval and sales under that did not have to be called in. Exceptions were restaurants which seldom had floor limits, and electronics stores or jewelry stores which always had to call everything in. If a merchant was suspected of being friendly to fraud users, the credit card office would make him call in every sale. Since there was no such thing as online terminals at every desk, the people who did the sales authorizations worked from ledger cards printed out showing the customer's last billed balance, and they had to pencil in the new sales on that card. Another authorizer the next day would see the hand written notation in the book that the customer had been approved for a hundred dollar sale the day before and he would not allow any more sales on that card. Since in the early days VISA (BankAmericard) had 'only' about a million customers (Diner's Club on the other hand had about three million as did American Express in the 1960's) that required about 150 people to staff the phones in a large room. Rack after rack and row after row of customer ledger cards; the authorizers wearing headsets with very long cords on them; walking around the room looking for the customer's ledger card to jot down the latest purchase. On any given day several thousand cards would be missing because the bookkeepers had come and taken them away to do the billing for that cycle, so if no card could be found for the customer then the authorizer just automatically approved the sale unless he saw the card listed in the 'hot card bulletin'. Since the bookkeepers *always* had priority over anything/everything else in the office, the authorizer could walk up to one of the stacks, start to pull the drawer out to get that customer's card and a bookkeeper with a push cart would come along, yank the drawer with a couple thousand customer ledger cards out right in front of him, set it on the push cart and walk away with the whole thing while he was still looking for the desired ledger card. Other times the phones would get so incredibly clogged and backed up with calls the supervisor of the authorizers would 'raise the floor limit' (typically in those days I think it was anything above twenty dollars) to thirty or forty dollars. To clear the backlogged phone queue, the authorizers were told to approve anything and everything up to forty dollars without bothering to look at anything or write anything down; just give an approval code number and disconnect, move on to the next call. Once they got the phones under control again, the floor limit would be reduced to what the merchants and customers expected it to be. Diner's and American Express went from *completely manual* billing on credit cards to semi-computerized systems in the early 1960's. VISA started out semi-computerized; all of them had gotten almost totally automated by 1980. My experience was with the Diner's/ Amoco Credit Card Office in Chicago during the period 1967-74; the sales authorizers finally got 'on line' about 1973 with terminals to look at rather than cabinets full of ledger cards but customer bills were printed by computer beginning about 1965. Now, everything is done at 'point of sale' terminals; your card is swiped and the transaction posted to your account; you reach your limit and that is that. Even though the cellular companies still do 'billing by the batch' after the fact, you'd think there would be a way the towers could transmit some sort of 'memo billing' information to the carrier. It wouldn't be perfect, but it would give the carriers a good idea of what any given customer's bill was going to be like that month. That, plus interim reports to the collectors at the mid-way point in the billing cycle with what had been posted to that date would allow some rather good controls. The collector would then, based on the customer's history, decide to either pull the plug, or contact the customer by phone to ask for money, or what- ever.

Well, it doesn't exactly "close the flip". It is indeed about a quarter inch long, located in the flip approximately below the END button at the right edge, and it activates a reed switch which is your secondary SND/END key which automatically answers the ringing phone and ends a conversation when you open or close the flip.

Cell phones will work in the main Jeppesen Terminal, but not in the three concourses. So, if you're flying through Denver and want to use your cell phone, you need to ride a little subway train back to the main terminal, out to the non-secured area, and into a fairly noisy building that kinda looks like a spiffy shopping mall.

Personally, I never thought I would find myself in the position of defending anything that NYNEX does, however, look at what you are comparing. Flexpath is a DID trunk service.

You are supposed to be able to enter a phone number or numbers that you do not wish to accept calls from, and the caller will be routed to an intercept stating something politically correct in that you aren't taking calls at the moment. Well, here in Bell Canada land, we frequently receive Caller ID from the US. Some travel and promotion company in Tampa, FL was calling several times during the day, and hanging up on the answering machine. Problem is, that I was generally asleep at the times the calls came in, due to working midnights. Attempting to enter the offending number resulted in a message "the number you have entered can't be reached by this service." I tried it several times in two different ways, 813-915-XXXX and 1-813-915-XXXX. Each time, I'd get the above message. However, if I used #01# to reject the last calling party, the system would accept the number, and tell me, the "the number you have entered is 813-915-XXXX. Please continue..." . This works great, providing you don't have any subsequent calls between the time the offending number calls in and the time you go to block it. However, if I enter a number in Bell Canada territory, such as 416-274-XXXX or 1-905-625-XXXX, the system will accept it for blocking with no problems. Is there a bug/flaw in the setup of my telco's implementation of Call Screen, and is there a known fix that I can bring to their attention, as so far they say they can't find any problem.

PAT] The classic rejoinder to the Bell System comment is that if everyone over the age of 18 were employed as a telephone operator, there would be nobody left who is not a telephone operator ... and therefore, nobody to place all of the telephone calls these operators would be waiting to connect! The same is true for customer-service personnel. The number of providers is, indeed, too small in many companies and in many government agencies. But continually increasing the number of servers will, at some point, diminish the number of clients, and therefore, the demand for service. Dave Levenson Internet: dave@westmark.com Westmark, Inc.

I got called back by a repair clerk a bit later but was not here to take her call, however her *seven digit number* was on my caller-id display. So I punched the button on my box that calls back the number shown on the display. We talked a couple minutes and she promised to call me back. Instead of her calling back, maybe ten minutes later I was called by a very high level person in repair with a complaint about me: "You are using *unauthorized numbers* to call direct into our repair department. You are not to do this again and if you do you will get in big trouble, Mister!" I told her all I did was return a call to the number displayed on my caller-id box -- the service they sell to people, remember? -- and maybe she was the one who needed to get into some Big Trouble, and could I be of assistance in getting that accomplished? She had *no idea* how caller-id worked, or that internal numbers at Bell showed up on display boxes just like all other numbers, but she supervised a bunch of repair clerks, by golly ... since her number was on my display box also at that point when we hung up I dialed her back the same way, and she was furious.

If the numbers are too high you'll see that it is not possible for that much fraud to go on unless the per minute charge is some high, high figure. This would just help see if the figures fit in with reality or not. Doesn't do anything to confirm if the figures are accurate. Tell her she should do a follow up article on how they uncover the cloning operations. I don't know for sure, but I suspect they have equipment to detect receivers tuned to the coordination channel of the cellular band. Then they probably sit some place where there are traffic jams regularly and then scan for people who have receivers tuned to the coord. The equipment would have to be very, very sensitive. The cloners, on the other hand, may be aware of this and are probably taking counter-counter measures, including heavy shielding of their equipment, etc. etc. Bob ------------------------------ From: pritter@nit.AirTouch.COM (Phil Ritter) Subject: Re: Cellular Fraud in the News Again Organization: AirTouch Cellular, Los Angeles Date: Mon, 20 Mar 1995 22:16:45 GMT In article telecom@eecs.nwu.edu (TELECOM Digest Editor) writes: > Over the weekend in the {Chicago Tribune} writer Kathy O'Malley offered > an interesting article on cellular fraud, primarily discussing how > phones are cloned and then abused. > The thing which caught my eye, and which I discussed with her briefly on > the phone Monday morning was her tossing around of the figures given to > her by some industry people: $1.3 million per day in fraud; and that > this represented four percent of the industry's annual traffic.

It is a difficult subject, somewhat like a religious argument, that we are unlikely to come to terms upon. Besides, I'm much too close to it to be objective and may have to deal in proprietary information to talk intelligently (which I am not authorized to do ... [reveal proprietary info, that is :-)]). However, the "annual revenue" for the "cellular industry" that is implied above is not only not astronomical, but probably understates the the actual industry revenues (well, OK, it is astronomical, but in the context above Pat also implies that it could not possibly be that high -- I contend that it is actually higher!). Here's how I back up that claim: Get a copy of "AirTouch Communications Facts & Financials" dated February 8, 1995 (order by calling Investor Relations, 415-658-2040). I am using this public information so that I do not have to deal with anything that might be proprietary (and that might get me into trouble ;-). Note that AirTouch' "Domestic Cellular Proportionate Results" shows domestic cellular revenues $1,149,0000,000, which mostly represents Los Angeles, San Diego, Atlanta, Sacramemto, and about 1/2 each of San Franscisco, Michigan & Ohio. There are a few more minority interests, but they are probably not significant for this "back of the envelope" argument. See Page 14 of the above reference. Assume that all of these markets are highly competetive and that that other system in each of these markets have approximately equal revenues. These markets then represent $2,298,000,000 in annual revenues. The "astronomical" industry revenue represented above is $454,000,000/.04 = $11,350,000,000. AirTouch and their direct market to market competetors account for 20.25%. Note that this revenue only represents 5.5 markets; No stretch of the imagination to see that these are less than 20% of total cellular markets and revenue. Therefore, the baseline implied for industry revenues is not inflated. No, Pat, these figures are probably realistic, not inflated. Now, the hard $$/soft $$ debate can continue without assuming that the baseline figures are inflated. Phil Ritter pritter@la.airtouch.com [TELECOM Digest Editor's Note: I did not get into a 'hard/soft' discussion with her; I wanted to see mainly if anything could be done with that '$1.3 million per day which is four percent of annual revenues' comment. I don't know how far I would get with her on the 'hard/soft' discussion anyway; her interest in the matter is as a consumer. She said to me her entire knowledge of cellular phones was that 'she turns it on and expects it to work ...'. She said she was inspired to write the piece based on the two instances of cloning which happened to her in the past year. Basically it was a good article and pretty factual.

I think it will be difficult to get that number. Most companies are rather reluctant to provide that info, and it's a moving target anyway. I had a cellular fraud presentation last year, and the amount of overseas air time a cloned phone can ring up is wild! Up to $5500 a day per phone! This company regularly looks at the top ten daily users and cuts off on average six of them. They look at each phone's background, calling patterns, etc. If Joe Average has no record of calling Red China and is suddenly ringing up 18 hours of calls there, you're pretty sure its fraud! To fight this they don't give overseas calling privileges automatically. You need to ask for it. Also some carriers are now using PIN ID. Every call or LD call, you need to enter your PIN first. They also had alot of voice mail fraud. Alot of people use their last four numbers as their password. People can easaly figure out which block of phone numbers are assigned to cellular and hack in, change the password, then use the box for automated third party LD approval! They would change the persons greeting to yes,yes,yes,yes,yes,yes,yes, ... Then they would call the automated operator and tell it to bill to that mailbox number. The operator would call the box, wait for an acknoledgement, get 'YES' and put the call through! The companies have had little help from the overworked police, so they don't get to prosecute much. They just try to stay ahead of the game. Later, Mike ------------------------------ From: mds@access.digex.net (Michael D.

All kinds of messages with things for sale; personnel recruiting (head-hunting) type messages, etc. One person at some personnel company sends me a dozen messages at a time about the kinds of people they are looking for on behalf of their clients. And the nervy part is, not once do any of these jokers offer to send me nickle one ... they heard the Internet is 'free' and can't possibly imagine why they should have to pay to help support it. On three different occassions this person has sent me a big bunch of messages looking for people to fill various positions. I wrote back once saying 'you know, you charge your clients big $$ to fill these positions, how about becoming a corporate sponsor here in order that I can improve the Digest for all the readers ... who knows, I might develop a mailing list for the exchange of human resources information for the readers ...'. Instead of getting back an answer to that, instead I get two more big batches of messages to be run. :( Every small business is now setting up a home window they want you to look at, and they want me to tell you about. I do tell you about quite a few of them, but I can see where that is going to have to stop soon also; I've been reluctant to help some in this way while refusing to help others, or to show favoritism, but it is going to have to halt soon. None of them bother to read the archives or the back issues; they don't even want to subscribe presently; they just want a place to dump their commercial messages. Some days I feel like so much of my time is wasted doing this stuff.

For this type of application, 1200 baud is the best speed to use. The connection is so short that a faster modem would take longer in training than the data transmission at 1200 would take.

Unfortunately, if I want 48 numbers delivered on two T1's (perhaps because I have a US Robotics modem chassis that takes T1's and turns them into Ethernet packets), I wind up paying the same premium as the customer who wants DID service.

Techie SOs Unite! SIGNIFICANT OTHERS SPEAK OUT !!! By: Shirley Clawson So you've found yourself attracted to a computer nerd. (Sorry techies; that IS what those of us that exist in the real world call you.) Spousal units and significant others (collectively referred to herein as "SO's") who have long endured the idiosyncrasies of their techie mates have banded together to provide the unsuspecting "future significant other" a peek at existence with: THE TECHIE. But first, a couple of disclaimers: All persons and events portrayed in this article are real and any resemblance to actual people or incidents is entirely intentional. Techies portrayed herein are of the male variety but male SO's have confirmed that they experience the same phenomenon in relation to their female techies. To properly co-exist with a techie, you must first understand three basic premises on which his view of the world is based: 1. There is a proper order in the universe. Computers come first; significant others somewhere thereafter. 2. Programmers, while reluctantly admitting (subsequent to intense pressure) that they are not God, are however, equal to God. 3. Computer illiterate people are complete morons. These three premises result in techies having a drastically different way of thinking as compared to the average person. This unique approach to life will be exhibited on a daily basis in many subtle ways: TOPIC WHAT YOU'RE THINKING WHAT HE'S THINKING ============== ======================= =========================== Ideal Vacation Tahiti Las Vegas -- during Comdex Shopping Trip New wardrobe Computer bookstore Eating Out Chez Romantic Vending machine at the office Fun Weekend Picnic in the mountains Non-stop programming 6 A.M. Romantic sunrise Late night of programming People over for Dinner Friends, Conversation Victims to view latest software developments Tax Time Call an accountant Order a tax package for SO Looking at Stereo Equipment Casual browsing Select model, Close deal Share Housework 50/50 Refrain from complaining that Pepsi isn't restocked Spending more time with Children Interactive Learning Set up Barbies next to computer Reason to cash out Investments Child's Education This years BMW's look good It is true that techies rarely subscribe to GQ magazine but, in all fairness, let's dispense with the slide-rule, taped glasses, white, button-down shirt stereotype. They no longer wear slide-rules; laptops are in. Taped glasses -- well, ok, sometimes. White shirts have been replaced by t-shirts and flowered Hawaiian atrocities. "Dressing up" for a special occasion entails putting on jeans and a wrinkled shirt with a collar. If you happen to be domestically inclined, don't bother ironing shirts (or if you're not, feeling guilty about NOT ironing them) because pressed shirts are simply not a priority in a Techie's life and neither he nor any of his contemporaries will notice that the shirt he's wearing looks like it's been trapped between his mattress and box springs for a year. Material possessions are of vital importance to the techie. Of paramount importance is: THE CAR. The cost of this is directly proportional to the size of: THE EGO. There are two types of vehicles owned by techies: 1966 station wagons with deteriorating wood on the sides OR the most expensive vehicle income will allow. (Neither category would be caught dead, however, driving a car with a Mary Kay bumper sticker attached.) Single techies can be identified by their dumpy apartments, frayed clothing and impeccably maintained Ferraris. Techies with vehicles in the second category assemble their machines for the annual Testosterone 500. Grown men gather at an area race track, spend 90 percent of the day walking around bragging about their car to anyone who will listen and devote the balance of the time tearing around on a track hoping they won't kill themselves. What we are witnessing is NOT simply a car race, but rather a battle of the egos. This same group of techies has also mastered the art of maneuvering discussion of THE CAR into every conversation. The home computer system is another source of competition. Our family of four (techie, SO, eight and two year old) is the proud owner of six computers, seven monitors, three laser printers, two dot matrix printers, two scanners, two optical disk drives, a CD ROM drive, and four boxes of cables that "might come in handy someday". Most appalling of all is that the two year old is limited to a 286 with an EGA! HORRORS! Special effort is made to explain to visiting techies that we are in the process of upgrading her system. Other elaborate electronic devices run a close second to the "home computer competition". Techies must always have the latest and the best of any electronic device on the market and they MUST be the first in their group to own one. We have established true superiority with our home PBX phone system with the capacity to handle ten incoming lines, conference calls, 45 auto-dial numbers and, best of all, music on hold. Oh, and our answering machine has voice mail capabilities, can receive fax transmissions and makes dinner. As you've probably already noticed, dating a techie has special challenges and rewards. Although your social hours are restricted to 11:00 p.m. - 3:00 a.m., you do have the opportunity to meet other SO's who, like you, are hanging around the office waiting for "just one more compile". A techie's estimate of "15 more minutes" generally means they will appear an hour or two later having absolutely no clue that more than 15 minutes has passed. If you do manage to convince your techie to take a vacation, plan on his inspecting the computer system at every hotel, gas station, restaurant, car rental agency and airline. Expect him to make suggestions for improvements to busboys, valets, maids and waiters, none of whom have the remotest interest in their establishment's computer system, much less any influence in this arena. Keep in mind also that no matter where you go, techies will find each other. The first trip I, my sweetie and his portable computer took together was to Europe. I was one of the lucky few to be dating a man who owned one of the first portable computers manufactured, which of course automatically entitled us to first class service everywhere. He no sooner had placed the computer on the airline tray table than six fellow techies leaped to his side to discuss the merits of the computer. Personal conversation with my traveling companion totalled ten minutes out of a six hour flight. Lunching with a group of techies is comparable to being dropped into a remote village in central Albania, with one major difference: Sign language is completely useless. They are speaking a foreign language and they are completely oblivious to this fact. My suggestion: Don't bother going. No one will notice that you were there anyway, including your techie. Parties dominated by techies are truly exciting experiences. Techies have never developed the art of smalltalk (their computers don't require this attribute) so don't expect to see a techie talking to a non-techie. If a techie was forced to bring his SO, he will feel obligated, however, to forego technical discussions for at least the first ten minutes. If you are unfortunate enough to be an SO with a "real job", you will encounter additional difficulties. The techie cannot fathom anyone going to work earlier than 10:00 a.m. He will tell you to simply inform your boss that you won't be starting until then. Techies are very well read. They devour books and articles on such exciting topics as memory management, VXD's and debugging but give them a book on relationships and watch the panic spread across their faces. Mention a couples workshop you think both of you should attend and watch those deadlines move up. At some point in their relationship, the SO must reveal to the techie that a romantic holiday does not entail bringing along a portable computer, stacks of computer magazines and a trunkload of listings. They will be expected to spend an entire weekend without their computer! If you make it through this traumatic experience, a marriage or move-in-together proposal may be in the air. Expect any proposal to be very practical. Important issues such as what kind of dog you will get, how much money will be allotted to ego-related purchases, and how much space will be allocated for the special, hands-off place for his computers in your future home must be settled before a techie will even consider a permanent relationship. (Critical tip: This allotted space will double in size within six months, often spewing out into other areas of your home if you have not planned ahead.) Your wedding date will be arranged around development conferences, COMDEX and technical crises. If, at some point in your relationship, you decide to have children, you will have to fit baby-making in between compiles. If you do manage to conceive, take a few photographs of your techie to tape over the baby's crib so your child will recognize your techie's face as well as his back. On a personal level, the techie is very supportive of his significant other. When I decided to diet, my techie stood by me and agreed to diet with me; as long as he didn't have to give up Pepsi and Twinkies. When I determined that I needed a new look, he promised not to laugh when I came back with a new hairdo and agreed to unlimited funding for purchases made at lingerie shops. The techie is also an accomplished gift-giver. Just last month, for my birthday, my techie gave me a Bug Zapper. (You know, one of those things that vaporizes the bugs flying around on your patio.) It seems he "heard me mention that we should get one." Guess he missed the references to the diamond necklace and pearl earrings. Last Christmas I was the proud recipient of a portable toolkit -- it's a beaut. Well, I'd better close now. I'm due for my 10:43 appointment to review the 1991 COMDEX floor plan with you-know-who. Never a dull moment ... -------------------- Biography: The author is married to a techie who denies exhibiting any of the aforementioned behavior and feigned ignorance when asked if he noticed these characteristics in any of his fellow techies.

(1-800-827-6364) Reply-To: mstrandrew@aol.com (MSTRANDREW) I asked a friend recently to call me from his work phone using my new ATT 500 number. He indicated that the local phone network accepted the 500 number, but the call would not process through FTS. Does any one know if FTS is going to get the message? I understand that FTS does not process international calls as well as calls to Canada. Since I call program my 500 number to any number in the world, I wonder if FTS wants to avoid accepting 500 numbers so that calls can not be forwarded to points outside the FTS system. On a totally unrelated note, does any one know if thought was given to assigning new NPAs to Guam (671) and American Samoa (684), so that they could be treated as "domestic" calls?? [TELECOM Digest Editor's Note: In both Guam and American Samoa the locals refer to themselves as 'area code 671' and 'area code 684' when giving their phone number to persons needing to call them. Strictly speaking this is not true yet, but a recent chat I had with someone at Bellcore leads me to believe that soon enough the '011' international prefix will not be needed to those two points and that their area codes will simply be the country codes they have been using all along. Speaking of the South Pacific region, the 808 area code which traditionally has been just Hawaii was expanded about a year ago to include Midway Island and the United States Trust Territory collection of islands.

C-bits are essentially only to be altered by DS3 sources. In the M13 arena, M23 mux sections use the C-bit to indicate the presence of stuffing. Whereas in C-bit parity applications it may be used for something else (like performance monitoring on the fly ...) The two coax connections are needed because each coax is a side of the channel (i.e. one for transmit, the other for receive). Fiber systems have these two coax connections for each DS3 also. The only thing that may come in the middle of any DS3 connection is just a manual jack field (DSX-3) or an electronic cross connect (an automatic version of a patch panel). ------------------------------ Date: Tue, 21 Mar 1995 09:04:27 -0800 From: RICHARD M KENSHALO Subject: Re: T3 Framing and Connection On 19 Mar 1995, Phillip Schuman <72510.1164@CompuServe.COM> wrote: > I'm looking for some brief explanation of the two kinds of framing > on T3 - M13 and C-parity. I'm pretty familiar with D4/SF and ESF. Two basic formats are used, each composed of the basic M-Frame structure. Both channelized (M13 format) and un-channelized (C-Bit Parity) service applications are supported. The various applications of the basic M-frame structure are distinguished from one another by the way the 21 C-bits are used. M13 format uses the 21 C-bits for bit stuffing. C-Bit Parity uses the C-bits for maintenance purposes. M13 Format (Subrated/Channelized DS3) - The M13 format will allow a DS3 signal to be channelized into 28 DS1s. C-Bit Parity Format (Subrated/Channelized and Non-Subrated/Non- Channelized DS3) - C-Bit Parity can be used for either channelized or non-channelized DS3 signals. It is recommended in all cases for non- channelized DS3 service because of it's superior maintenance capabilities over the standard M13 format. DS1 to DS3 multiplexing (channelized) using the C-Bit Parity format is the same two-step multiplexing process used for standard M13 (channelized) format except that bit stuffing is done at every opportunity during the second step of multiplexing. Since stuffing is done 100% of the time, the C-bits are no longer needed to indicate the presence of stuff bits, and are used for proprietary maintenance overhead capabilities. In the C-Bit Parity format, the 21 C-bits are allocated as follows: AIC = Application Identification Channel: 1 C-bit NA = Reserved Network Application bit: 1 C-bit FEA = Far-End Alarm bit: 1 C-bit DL = Data Link bits: 12 C-bits CP = C-Bit Parity bits: 3 C-bits FEBE = Far-End Block Error bits: 3 C-bits Path Level Monitoring Implications: M13 vs. C-Bit Parity Formats: With the M13 format, the only available path level monitoring technique is to use the P-bit, which is a parity designation for the entire payload (4704 bits of data). The problem is that most networking equipment interfacing at the DS3 level was designed to segment the network on a point to point basis. Thus, at intermediate points along the network, the network equipment corrects the value of the P-bit before transmitting the signal along the DS3 line. This results in no complete monitoring on a path basis. Path level monitoring using the C-Bit Parity format allows end to end monitoring of the path level since these bits are not altered anywhere along the path. Also, the FEBE allows the far end to indicate to the near end that a parity error on a block of data has occurred. > Also -- on a picture of the Digital Link T3 mux -- there are two BNC > connectors; are both used, or in/out or what? How does this work in > connecting to a fiber based system like T3 -- is there another > interface box between the telco and the CPE? One BNC is DS3 IN and one is DS3 OUT. No other interface box is required between the telco and the CPE, as long as the DS3 meets the following electrical interface requirements: Electrical Interface 1. The pulse amplitude shall be between 0.36 volts and 0.85 volts (peak), measured at the center of the pulse. 2. The transmission rate of the DS3 signal shall be 44.736 Mbps plus or minus 895 bps. 3. The line codes for the DS3 signal shall be Bipolar with 3 Zero Substitution (B3ZS). 4. The test load shall be a pure resistive termination of 75 ohms at the network interface and shall be used to evaluate signal characteristics. Hope this helps.

Here's the long version: I have a Windows-based PC that I'm going to use as a word processor and telecommunications machine and a new Power Mac that I'm using as a graphics and desktop publishing machine. I'm trying to figure out, without success so far, how to download Mac software with the PC and transfer it so it's usable with the Mac. I understand that Mac software has these resource fork thingies, which complicates things. What I've done so far is grab from Apple's FTP server four files that update System 7.5 (they each have the extension .hqx). They're now sitting on my Windows PC's hard disk, renamed to conform to DOS 8.3 naming conventions (I'll rename them back once they're on the Mac's hard disk). One problem is that two of the compressed files are larger than 1.44 MB, so they can't fit on a floppy as is. The DOS program PKZip could handle this problem. I've downloaded the Mac PKZip unzip program. I actually found two program. One has the filename mac-unzip-50p1.hqx, the other is named unzip-201.hqx. I believe you need the program StuffIt (or equivalent) to unstuff these files with extensions .hqx). So I also downloaded UnStuffIt.1.5.bin. I'm not sure what the extension .bin means. Does it mean it can unstuff itself by doubleclicking on its icon? Well, I copied UnStuffIt.1.5.bin from my PC's hard disk to my Mac's hard disk, but when I doubleclicked on it, I just got a message that Apple File Exchange didn't recognize it. This is a Mac program so it doesn't need Apple File Exchange, but my Mac thinks it's a PC program. So this is where I'm stuck. One option would be to get a Mac telecom program and move my 14.4 external modem to the Mac whenever I needed to download Mac programs. But this would be inconvenient. I'd rather try to find a solution where I could simply use a floppy to transfer Mac programs to the Mac that I downloaded with the PC. Any advice greatly appreciated. ------------------------------ Date: Tue, 21 Mar 95 00:43:46 PST From: Jennings Subject: Alarm Reporting Black Box Is there an "off the shelf" black box that will take an alarm output from a system or subsystem and dial a phone number to report the state of the alarm output ... the black box should have a modem built in and would call another modem that would be in the auto answer state, and after the exchange of handshake, dump the status ... this must be a common requirement, it seems to me, does anyone have a vendor of this kind of stuff, a part number?

As far as I have been able to decipher so far, some conversions between Dialogic VOX and Microsoft WAV files are (all values are hex): WAV VOX --- --- 001 000 (near minimum value for WAV file) 080 0FA (near middle value, 0 magnitude for WAV file) 080 0FB 080 0FC 080 0FD 080 0FE 080 0FF 081 0F0 082 0E0 083 0D8 084 0D0 088 0C0 090 0B0 0FE 080 (near maximum value for WAV file) Any help or suggestions would be greatly appreciated.

I picked up the phone used and want to add it as an "extension" to my mobile phone number. I seemed to get everything almost correct and wanted to change another item in the nam, only to find out that I have a phone with three runs at programming before you can do no more. Do you know of any more detailed info on how to reset the nam so I can continue with my programming effort? Or, do you know where to get information on the net for creating the extension phone with my Motorola brick? I have heard that this information is available, but don't know where. Thanks for any and all help. Thanks, Jim jknoll@winternet.com [TELECOM Digest Editor's Note: What you have to do is put the phone in 'local mode'; that will give you a lot more programming options including one to reset the counter which keeps track of how many times the phone number has been changed. For many/most cellular phones, putting it into 'local mode' involves shorting a contact on the phone where the battery is connected. Notice from schematics that one of the pins on the connector is chassis ground. One of the other pins has to be held low, meaning shunted to the ground. One way of doing this is to get one of those connectors at Radio Shack which allow you to open the case and move the arrangement of the pins around. Typically they are used to reverse pins 2/3 (or is it 1/2) between a computer and modem, but you can use it just as easily for this purpose. Drop a teeny tiny bit of solder in there between the two wires in question causing a short. Then plug the battery into one end of this and the other end into where the battery would normally be connected. What happens is you now have caused the pin in question to go low -- or to ground -- and when the phone turns on it will be in programming mode. When done programming just pull this device out of the line and attach the battery in the normal way. You can do lots of interesting things in local mode including punching in whatever channel you want to be on *whether or not it is in use* then sitting there and listening to the people who are using that channel. You can boost the power on the phone up a little; this is sometimes called 'burning' a channel. The main thing is you want to reset the register which keeps track of how often the phone number has been changed back to zero. I forget which pin needs to be grounded, and it may vary from one model of Motorola to another. If you have forgotten the lock code and find yourself locked out of the phone you can also use 'local mode' to cure that; one programming option lets you zero out everything back to factory default, giving you a 'phone number' of 000-000-0000 and a passcode of 0000. Someone who has the programming manual will proabably write you with specifics, but bear in mind you do need that one very minor hardware modification in the power supply. For extra credit in this class, do this: mount a tiny toggle switch on the side of the phone which allows you to toggle in and out of local mode as desired. Cut the wire to the chassis ground and send it through that little switch and out to the desired pin (or not) depending on the position of the switch. Then when you have used up the three chances they give you with the phone number, just press that little switch for a few seconds, punch a couple buttons on the keypad, release the switch and start over! :) I'm sure others will be in touch with you soon.

Where did you get this figure? When I calculate it it works out to $3.27 per MB. 1 MB = 1024K = 1048576 Bytes = 8388608 bits = 65536 octets (1 octet=128 bits) 65536 octets * .005 cents = 327.68 cents = $3.27 And yes, that is a lot cheaper than the approximately $9.90 that it would cost to transmit the same amount of information over a 1200bps modem (what the poster orignally asked for).

Actually, there are 16 bits per two byte octet. Therefore: ((0.005 cents)/16 bits)*(1,048,576 bits/Mbit) = 328 cents/Mbit, or $26.21/Mbyte, still rather pricey!

NYNEX does "bundle" DID service into Flexpath, and ISDN PRI, so you only have to pay for the numbers. If you don't need 100 numbers, you still pay for DID service. That's minor. What's really dumb is the way NYNEX prices both T1-based services. The idea they use is that T1 is a PREMIUM that adds VALUE to the service, so you should pay THEM for it. This made some sense back in 1985 when they introduce it, since they had mostly analog CO switches. Flexpath was implemented by sticking a big fat D4 channel bank next to the switch, running 24 wires into the D4, and giving you a T1. Nowadays, of course, the CO is usually digital, so the economics are flipped around: Analog lines require the extra hardware. But the tariff is unchanged. This causes NYNEX to waste money. Another dumbness in their tariff is the pricing for the T1 loop itself. For an analog loop, distance is THEIR problem. If you build a factory six miles from the CO, then they string fat wire on the poles, or do whatever they feel like doing, but the price is the same. (There is no "rural" area in Mass., at least; some states have surcharges.) For T1 loops, they charge mileage from the CO, so it's quite costly if you're even three miles out. This enocurages the use of costly separate pairs for the long runs, and cheap T1 muxing for short runs -- ecoomically counter to NYNEX' best interests, unless they're really more interested in padding the rate base.

I graduated in May of last year with a dual major BS in Computer Sci and Geography (gis). I've got a car loan and two credit cards. I pay my full credit card balance monthly, and I have a few thousand left on my car loan. I travel a lot, and I wanted a phone for my 'peace of mind'. I walked into the local Cell One "phone store" cash-in-hand. I was ready to pay up front for the phone. (In this area, One likes to push expensive phones on payment plans.) They ran a credit check on me and decided that I'd need a $250 deposit to open a cell account. I left, walked down the street to Wireless one, bought the same phone for $70 less, and had service the next day, no deposit required. As far as I'm concerned, Cell One lost my business. I'll never recommend them to anyone I know. I went through the "write the credit agency to see why process" The response I got was that I had a low income, and an unsecured loan. Oh well ...

The hardest part of cloning a cell phone is having the correct equipment to program it. Intercepting the necessary data on a control channel is just a matter of having a few pieces of equipment that can easily be put together for under $1000, and then get into your dark panel van and sit under a control tower. As for detecting someone receiving control channel signals ... I don't see how, since sitting and listening on the frequency is a passive activity.

But I would like an opportunity to reply. It is true that television has consumerism built into it as a default mode, however it is you or I need to accept it blindly. Despite its faults, television is not an evil. My wife and I come from India. Television is our link with India. We see India every weekend. We also see China, Japan, Russia, France, Germany and Italy every week. This is something that only television can provide. Television provides information across ideologies, time zones, and governments. I am not willing to give this up very easily. If you wish to consume you can. I would like to be a willing consumer, however I cannot afford it, so I am relatively immune to the shrill consumerism of television. But neither do I speak ill of consumers, after all they are the engines of commerce, rightly or wrongly. May I suggest a bit of advice that an ancient Greek gave us, "Moderation, in all things, moderation. Even though Aristotle wasn't speaking about television, it makes sense. True, television is a lean, mean, consuming machine, but it need not be. It can be a teacher if you very, very carefully pick and choose. Similarly so, the Internet. Like television, I speak to friends in India and they talk back. I gather information about telecom, single malt whiskeys, what others think about investment in Russia and the latest CD. I am barraged by advertising, multi-level marketers and endless e-mails. I apply the same principle as I do about television. Pick and choose, very, very carefully. Like it or not the Internet has to grow up. Having fulfilled its destiny in the 70's and 80's, it needs to have another purpose. It is up to you and me to define and develop another purpose than commerce. Electronic town halls, referendums for states, towns and municipalities are all good alternatives that need to be developed. I have developed a use for the Internet. I am part of a virtual corporation. My firm is in Phoenix, Arizona and I sit here in Maryland, e-mailing, faxing, phoning and gathering information on the Internet. For me, the hacker is an entity who stands for anarchy and purposelessness, not connectivity and value. The future of the Internet is by no means certain or predictable. This is the first tool that can be shaped and you have that opportunity. As a final observation, 90% of television and the Internet is idiotic and irrational. So is life. But you keep finding value and substance in the oddest circumstances which is what makes it all interesting.

I've encountered help-line phone systems that let me peruse the on-line help information (FAQ & A!) without losing my place in the queue. [TELECOM Digest Editor's Note: They may have hundreds of techs employed there; they do *not* have hundreds of techs taking phone calls from the public. Think about it; if they had 'hundreds' of techs taking phone calls then they would be taking many hundreds of calls per hour and still not be able to catch up. This would put them in the league with the credit card offices, etc in terms of sheer volume of inbound traffic, and Microsoft does NOT have a phone room that size. Yes, they get plenty of calls; its that the typical call cannot be handled in thirty seconds or a minute. They've probably got at any given time a dozen or so people taking calls; that is just my estimate. Maybe they need to have a couple more, and some method of dealing with the most repetitive questions and answers which probably take up a large percentage of their time. To do that, you ask each of the regular phone people to list the two or three questions which come up over and over the most in a day's time. You then look at all the results and pick those things which every phone person said happens frequently. You take ten or twelve of those things the phone people voted 'most common' and you make recorded messages about them or you hire someone to manage just those calls. A person answering on the front end says 'what do you want to talk about?' and parks your call in one queue or another.

This is already implemented -- has been for years. Ever hear of the new Call Trace feature? The telco's don't advertise it because they lose (small amounts of) money on it. They should because it is one of the few positive developments to come out of the CLASS services, which include Caller ID. Caller ID blocking options can be provided while protecting the called party from abusive/threatening callers. Most states provide for the new "Call Trace" feature which provides the caller-id information to the telephone companies nuisnance bureau and potentially to the police (in a form that will stand up in court). The privacy of the caller is NOT violated because their number is not provided to the called party. It is provided only to the nuisnance bureau and the police. Just dial *57 after the abusive call, in a supported area. And pay $1.00 for the pleasure, in Oregon.

PAT] In technical terms, I think the CPC equipment detects an 'open switch interval' or OSI, where the CO drops battery momentarily or something like that. I think all digital CO switches today provide OSI (if you have a phone with a line powered dial pad light, you can check for this -- wait for someone who has called you to hang up, and watch the dial pad. The light on the dial pad will go out for about half a second then come back on. That is the OSI). When you are the calling party and *you* hang up, the switch disconnects the call immediately. If you are the *called* party and hang-up, the switch gives you a grace period of 15-30 seconds where you can pick up the phone again and re-establish your conversation (if the calling party hasn't already hung-up), before it disconnects the circuit and provides an OSI to the calling party. Of course, this may be different in your exchange. I don't know if you can buy an add-on device that will monitor OSI and disconnect the call for a non CPC-complaint device. But most decent answering machines from Panasonic, AT&T and others support CPC. Scot M.

What happens is you take all cells down to zero, and then recharge together. If imbalances were a problem they would occur at any level. In the event, the problem is that repeated discharges that are less than complete slowly lower the capacity of the battery. This occurs because of memory -- crystalization in the battery -- and occurs because, as a practical matter, we do not discharge a battery fully. Toward the end of its capacity, the battery cannot supply adequate voltage, and the radio or other appliance does not perform properly (it may have distortion, loss of sensitivity, drift off frequency, have low volume, etc.). So one discharges to this point, which becomes the memory point -- effective zero -- and then the next time one discharges "not quite" to this point, and so it goes. The only solution is do discharge the battery completely. Since we cannot do this in the appliance (cellular radio, or whatever) without tying up the appliance in some way, we must do it in the charger -- if the charger has a discharge cycle. If the charger does not have a discharge cycle (that is, discharge into a resistance to take the battery to real zero (which discharges into a load), then the obvious solution is to discharge the battery the rest of the way into a home-built dummy load. My suggestion is a flashlight bulb appropriate for the voltage. However, a resistor might be used. The following message which appeared on another network suggests that the problem you suggest is also solved when the battery is fully discharged into a dummy load. >This message was from JAMES MC SHANE to SCOTT SEAB, >originally in conference R-Phones >and was forwarded to you by DAVID CHESSLER. >SS> -=> Quoting Lou Ramsay to All <=- >SS> LR> A while back, someone posted a method of "rejuvenating" NI-CAD >SS> LR> phone battteries.

Anybody have any thoughts on this? It means that ANY new number requested will come with a 972. I don't understand why they didn't restrict the area code geographically and also to all new data/pager/cellular services and cut over all existing cellular service to 972 (for that matter, existing pagers, too). Wouldn't that free up tens of thousands or more numbers? The plan they have now will probably result in scads of wrong numbers being dialed. What if you have a business number of 361 5000. That number could exist in both area codes and it will probably get dialed constantly by parties looking for one of two different subscribers. I don't know about this plan ...

Most of the telco's are looking at HFC which delivers telephony via coax cable. This is due mainly to the cost of fiber-to-the- curb and fiber-to-the-house. HFC has been seen as the most cost effective way to get every one up on higher speed networks. BTTC is great for new places, but what about in existing neighborhoods? Most are already wired with coax. ADC Telecommunications (for whom I work) annouced a large contract with Australia last week for just such a system. We are also producing a version for the US. Others are also working on such systems...such as AT&T, Scientific Atlanta, Fujitsu, DSC ...(at least most of that list any way). It appears right now that the HFC system is the system of choice. Most of the current field trails are with FTTC ot FTTH systems, but it is the understanding of most people that this is not direction that most of the companies wish to pursue.

The Minister for Communications, Mr Sukh Ram, is to consider the Gupta committee recommendations this week. The committee suggested the creation of an autonomous organization, India Telecom, as a service provider replacing the DoT. This would be subject to the regulatory control of the Telecom Regulatory Authority of India (TRAI), which is in the process of being set up. While the TRAI would be analogous to the US FCC, the Telecom Commission would continue to formulate national policy, which may include the regulations to be enforced by the TRAI. The Commission would continue to supervise the operation of the autonomous Centre for the Development of Telematics (C-DOT), an effort at creating indigenous equipment that has proved extremely successful especially in rural telecom. A member of the Commission would also hold the ex-officio post of CEO, India Telecom. The government is good at funding committees and studying reports. One last year, led by Mr. M.B. Athreya, which suggested the break-up of the DoT's operations into four regional companies, was not welcomed by its half million or more permanent employees. The Gupta recommendations, which suggest independently profitable telecom 'circles' (regions) within India Telecom, may not be more popular. This committee is the latest in the government's attempts at fostering fair competition between the public- versus private- sector duopoly in telecom services that will be in operation by next year. --==(C) Copyright 1995 Rishab Aiyer Ghosh (rishab@dxm.ernet.in) --==May be distributed electronically provided that only compilation or --==transmission charges are applied.

A business associate who subscribes to caller ID finds that when certain parties call him from within his caller ID service area, their telephone numbers do not display on his caller ID unit the first time. The screen on his display unit is blank. However, when he has the same parties call back a second time, their telephone numbers and names will display. The display unit has been replaced three times in the past month so we don't think the problem is in the equipment or because of a low battery. Also, the local telephone company has checked the line for trouble and come up with nothing. Any ideas on this? Please post or email me if you do. Thanks, Roberta Splieth [TELECOM Digest Editor's Note: You say the first time the screen is 'blank'. Do you mean literally nothing shows up at all, not even just a few dashes, or some garbled characters? Most caller id boxes will respond to the ringing of a telephone with *something*, even if just dashes across the screen to indicate nothing was sent. I would begin by doing this: since you have already tried three different boxes on the same line and gotten the same results, try taking the box to some other line independent of the one it is on now and trying it there. See if the results on that (caller id equipped) line are the same. If so then maybe it is the box. If possible, install a caller-id box from some other vendor on the line where you are having the trouble and see if the problem persists with a display box *from a different vendor*. Let's try to isolate the problem as to display box or line and proceed from there.

The following are some ideas that are being considered: (1) LMA members who are "certified," would be offered higher commissions from the leading industry service-Providers. (2) LMA members will be offered 10 cent long distance rates for their own personal use. (3) The LMA will offer training and sponsor conferences. (4) The LMA will publish a newsletter/magazine specifically geared to long distance. currently, there are no long distance publications. (5) The LMA will track and report to its members unreliable service-Providers who fail to live up to their commitments to their marketers and to their end-users.

[ I wasn't wasting both of our time on purpose, really ] Perry Engle Engineering Services Liberty Mutual Insurance Conpany engle@lmig.com [TELECOM Digest Editor's Note: Very sad, and very true. Truer than it should be. A lot of folks have still never heard of those services; they know nothing about computers and very little about phones except that when they pick them up they work or don't work. Telco probably sent those telemarketers to a class -- or series of classes -- to give them enough knowledge to do the limited job they do. The classes prob- ably taught them a few basic -- very basic! -- details about the phone industry and products such as custom calling features. They got passing grades in that class and were offered jobs selling telco services by phone. They probably went home thrilled and told their families they had gotten a job working 'for the phone company'. That's why I wish people would not be so harsh with telemarketers; many of them are doing the best they can do in life. You can courteously say yes or no and hang up the phone and they can move along to the next name on their list to be called. Computer illiteracy *is* a major thing in the USA; despite the incredible growth experienced by the Internet and services such as Compuserve or America On Line, the overwhelming majority of Americans know little or nothing about them. They think its busy and overloaded with traffic now; wait until even as little as ten percent of America gets on line! I feel very oppressed when I realize how much needs to be done to educate people in (as an example) the inner city areas of Chicago. If I were to win the Illinois State Lottery today and pick up a few million dollars I would see to it that every public library in Chicago had an online terminal to the Internet, and a full time instructor to show people how to use it and how to participate. Do you understand where I am coming from? And as we hurl forward with our technological advances, a very distinct and definable 'underclass' of citizens -- people who will never join us in our new world -- is growing. The writer/poet John Bunyan once remarked that, "I am oppressed by things undone; oh! that my dreams and deeds could be one ..." . When I stop and realize how much *I* don't know about this industry in the past couple decades, and how much *I* need to learn to keep up what I said above becomes all the more painfully apparent. What the heck! I can barely keep this Digest going some days, let alone cure the rest of the ills I see around me.

All the above is true, but it leaves the impression that after NI-1 is deployed that there will be no more differences between the AT&T and the NTI switches. The different architectures developed by the different vendors, described by Mr. Weiner, have carried over into the NI-1 implementations. Therefore, there are still differences in the two switches, even under NI-1. For example, if you want to use both B-channels for data, you will need two Directory Numbers, two SPIDs and two TEIs, whereas AT&T requires only one.

You are a victim of what is a nice feature of the network. A called party may hangup for up to 18 seconds before the line is disconnected. The purpose of this is feature is to allow the called party to hangup the phone and move to a more comfortable phone. To bad they don't document this to the public very well, I only found out about it after working on the 5ESS switch.

Is this due to the Doppler effect? As I understand it, it's due to the speed that handoffs can be performmed. PHS users much smaller cell sizes than standard cellular, and handoffs speed is adequate when the telephone moves from cell to cell at a walking pace. A vehicle zooms through a series of these small cells very rapidly, and the system is not designed to perform the rapid handoffs that would be required.

Nevertheless, both title and subtitle imply a useful guide. To this end, each chapter contains tutorial material, discussion of the available tools, and examination of some specific problems. The authors have produced an application programming interface in Tcl and Tk, for both practical and tutorial purposes, which is available on the Internet. While the material in the book does a good job of explanation, the appearance it presents is *not* for the technically faint of heart. The overview of SMNP, itself, for example, is not filled with C sources, but a language much more frightening--that of protocols and standards committees. The perseverant can follow the text, but it does take some dedication. copyright Robert M. Slade, 1995 BKNTMGPR.RVW 950220. Distribution permitted in TELECOM Digest and associated publications.

I've had three people try to call me for a record of zero getting through. Then, of course, ATT tells me that *no* cellular phones can call 500 numbers because "the cellular carriers don't have any way to bill for the calls". Is this going to fly or not? christopher michael, george s. may international, 708-825-8806 x 395 [TELECOM Digest Editor's Note: 500 numbers are a new enough concept that most cellular carriers have not yet made any arrangements for handling such traffic. You can forward your 500 number to a cellular phone, its just that you can't call *from* a cellular phone to a 500 number. At least not yet. Back in the days when there was but one telephone company, and that telephone company saw to it that everything meshed together nicely and that all the parts could talk to and deal with all the other parts this would not have been a problem. Now that all the individual companies do their own thing with only a casual thought given to the customer -- and then, usually in the context of the customer being an interupption to their work rather than the purpose of it -- lots of the parts don't merge well with the other parts. Of course a rejoinder to this is that if there were still just the one Mother Company would we even have cellular service and 500 number service at all .... What happens when your associates attempt to call your 500 number from 'regular' or landline phones of the non-payphone, non-hotel switchboard variety, i.e. the phones in their home?

The thing is, I have good credit. Perhaps I can't buy a house, but neither do alarms go off when I pull out my credit card. :) I have two lines with RochTel, and a good payment history with them ... so I was a bit surprised that they were looking for a rather large amount of available credit on my line before they'd waive the deposit. This, in itself, isn't too objectionable ... but when they turn around and waive the deposit anyway when I balk, and instead just take my MasterCard number, it seems a bit sleazy. If I were a person walking in off the street with no references, I'd understand the need for protection. However, as someone who has kept a household for two years, and paid phone and long distance bills to the company in question without complaint for that time ... and someone who can afford $25k a year to go to the University ... it just makes me a bit uncomfortable. If it were really to cover their ass in event of fraud, why do they treat it like a used-car salesman treats the "dealer prep fee"? It's there until it looks like it'll lose the sale, and then it vanishes. My credit check through Equifax isn't good enough for them ... but my MasterCard, which at the time had $70 left on it, being Christmastime, was sufficient. This just doesn't seem to make sense! Rob Levandowski Computer Interest Floor associate / University of Rochester macwhiz@cif.rochester.edu [Opinions expressed are mine, not UR's.] [TELECOM Digest Editor's Note: The ridiculous part of it all is that literally *anyone* can get VISA or Mastercard, regardless of how bad their credit is. Both of those cards have lending institutions associated with them which offer 'secured' VISA or MC. That is, you deposit some sum of money in their bank which you are unable to touch ever again and they in turn issue you a VISA/MC with a credit line equal to whatever amount of money you had put in the bank. Having a VISA/MC is *not* a sign that one has good credit, particularly if you are in the industry and you can look at the first four digits on the card (which identify the bank issuing the card) then look the cardholder in the face and say, "but sir, this is a *secured* VISA ..." A few years ago all the major retailers were running a promotion where if you came in their store(s) and presented a VISA/MC as payment, they would give you 'instant credit' in the form of one of their own credit cards without bothering to do a credit check. After all, credit checks cost them money, and VISA had already done one, right? So people with lousy credit would tear off one of those coupons on the bus advertising sign saying 'regardless of bad credit you can have a VISA/MC' and send it in with a hundred dollars. They'd get back a VISA with a 'credit limit' of one hundred dollars, then take this card and go shopping at Neiman Marcus or Marshall Fields. The store clerk gets some small premium for each new credit card customer (s)he signs up that the credit office approves, so when the customer whacked his plastic on the counter, the clerk would say how would you like to have a Neiman Marcus credit card?. The savings for the store were obvious. Instead of having to factor that paper through their bank and lose a few points, they'd carry the paper themselves. The credit risk can't be too bad, they'd think ... after all the customer did have a pocket full of VISA/MC's ... Montgomery Ward got burned badly on 'instant credit' a few years ago, as did Rosendorf and a couple other chains. To make matters worse, unlike VISA, where its no skin off their nose if the merchant makes the sale or not and credit limits are pretty closely watched, the merchants were *really, really hungry* two years ago at Christmas time. Credit limits be damned! they said, letting customers with their in-house cards go way over limit lots of times in order to get a good sale. Their rationale was if we do not approve this sale on our card, the customer will simply use his VISA card to pay for it, and we lose the fee. If it had been me, I would have said "VISA will approve this sale? Good!!! Let them eat it ..." The catch in credit granting is to enhance the possibility of making the sale while at the same time keeping the costs involved with the extension of credit as low as possible. Fine tune the process to where creditors can make some reasonably sophisticated decisions regards who to give credit to and who not to give it to; how much credit to extend, and what to charge for it. Someone -- probably the same outfit which devised the worthless 'point scoring' tests the creditors use as a shortcut to *real* (and very costly) investigation of prospective customers -- put a bug in the creditors' ear that as long as some VISA/MC affiliate had approved the customer, you can do the same. So the merchants gleefully glutted the market with their own in-house cards only to have the bad debt get higher than ever. A very cynical person would say it must have been a scheme devised by collection agencies, many of whom have been laughing all the way to the bank because of their increased caseload in the past couple years due to 'instant credit' given by your friendly local branch of Wards.

ZMODEM needs an 8-bit, clean data path. If you're using telnet, that's often a 7-bit protocol. Also, some systems eat important characters like XON/XOFF, which ZMODEM wants to use. Our Xyplex terminal servers were notorious for eating control characters that ZMODEM wanted to use. You can try using the "escape control characters" mode of ZMODEM, but this may signifigantly decrease ZMODEM's speed. At UR, we recommend the use of Kermit because it's very difficult to make default Kermit fail completely. Yes, it's slow as molasses by default. However, if you change the packet size from 94 bytes to something more reasonable -- 5000 to 9024 bytes -- you'll see Kermit's performance leap right up into ZMODEM's ballpark. You can get further increases by using sliding windows (3 - 5 windows seems to work well) and the least necessary control prefixing. Kermit takes a bit of optimizing; you might try and get a copy of "Kermit News" No. 5 (July 1993) from Columbia University. That issue has an article on optimizing Kermit, and documents Kermit transferring a MS-DOS binary file via a v.42bis modem at 569% efficiency (8192 cps). The issue gives an Ordering Information phone number: +1 212 854-3703.

".bin" means it's in MacBinary format, a way of formatting a Mac two-forked file so that it can be transferred to a one-forked file system like MS-DOS or UNIX. You will need to decode this file before you can use it. Most Mac telecom programs do this automatically when you download. StuffIt will also decode MacBinary, but that would put the cart before the horse. You might want to check with a local Mac guru about getting a copy of StuffIt. Self-extracting files (which can be decompressed by double-clicking on their icon) usually have the suffix ".sea". Also, UnStuffIt 1.5 is hideously out of date. You should get a copy of StuffIt Expander 3.5 or later, and a copy of DropStuff with Expander Enhancer, which will let you decode PKZIP files with Expander. Expander is freeware and DropStuff is shareware. > Well, I copied UnStuffIt.1.5.bin from my PC's hard disk to my Mac's hard > disk, but when I doubleclicked on it, I just got a message that Apple > File Exchange didn't recognize it.

It's a file transferred from a PC, so the Mac assumes it's a PC program and sets its type accordingly.

To do this most easily, you'll need to get a copy of a program that can decode BinHex files. StuffIt Expander will do this. A local user group, or any computer dealer worth doing business with, can give you a copy. You can then download the BinHex (.hqx) files as ASCII text to your PC, copy the files to the Mac, and drag them to the Expander icon to decode and decompress them. There are programs out there that can convert .hqx files to MacBinary format and back, but until you have a Mac program that can convert .hqx or MacBinary back to the native Macintosh two-forked file format, you won't be able to use any downloaded applications. Any conversions before the Mac will wipe out part of the file when you save it to the DOS machine's one-forked file format.

I ridiculed this idea, saying instead of having a disk jockey play music, it would be better to hire a couple more people to take phone calls instead and move the queue a little faster. Someone responded saying 'if you already have hundreds of technicians taking calls, what good would one or two more do?'. I expressed some amazement at this and suggested that Microsoft might hire hundreds of tech people, but I was certain they did not have them all there to sit and take phone calls from the public eight hours per day. I suggested that perhaps a much smaller number of employees actually took phone calls. I got a phone call Wednesday afternoon from someone I had not talked to in years -- since a previous lifetime actually! -- by the name of Shawn Goodwin. Back in the early 1980's, he lived in (I think) Downers Grove, Illinois and operated the 'Suburban Round Table BBS'; it was an Apple ][ BBS running Bill Blue's software. The purpose of his call was to put me in touch with a woman who formerly worked for Microsoft as a supervisor of the techs who answered all those phone calls. I spoke with the woman for about twenty minutes in a conference call with Shawn, and it was very enlightning for me to say the least. It showed me the way different people, doing a lot of the same work, but from much different directions can have vastly different perspectives. I've been involved with big phone rooms at one time or another; a dozen or more people on each shift handling in total thousands of calls daily in a bang! bang! bang! kind of environment, with very sophisticated record keeping and telecom equipment. As a result, I assume I know something about phone rooms and long holding queues and how to manage the callers waiting, etc. The woman told me a much different account of things. It seems Microsoft does indeed have *hundreds* of people, whom they call technicians taking calls at three locations in the USA. This woman was responsible for super- vising quite a few of them when she worked for Microsoft. I asked her if you had hundreds of people taking calls seven or eight hours per day, how many thousands of calls must you have received, with people waiting in line for upwards of twenty minutes yet to get through, and a DJ who tells you there are eighteen calls ahead of yours, etc. It was not that there was such a huge volume of calls in terms of the number of calls as it was that *each call lasted an average of nine minutes*. Many calls took quite a bit longer. Many times, she said, the technicians had to literally start from the beginning with a customer and go from the initial installation of the software forward. They might have to get into things like the customer's config.sys file and almost re-write it all. Naturally there were the customers who read in the book to press 'any key' who called to say there was no such button on their keyboard marked 'any'. Seriously. She said a relatively small handful -- one hundred perhaps, or maybe two hundred -- of customers always called them repeatedly, over and over. These poor souls had to be walked through everything, everytime. This was the reason the queue was so sluggish, despite *hundreds* of people taking calls. The average nine minute call is what shocked me. I found that incredible and still do. This illustrates well the different directions people travel to get to the same place. In the phone rooms I worked in, a nine minute call would have been outrageous, and if holding time in the queue got to more than one or two minutes -- perhaps eight to ten calls holding -- the supervisors got frantic. And we handled perhaps ten times the number of calls daily that Microsoft gets. So I asked the lady, if Microsoft had to spend that much time and effort and personnell -- with the inherent payroll costs involved -- in providing customer support, where is the profit in developing software? Well, she said, that was the hangup; there wasn't much profit, not as the system was configured. Yes, there was some, and she said customer support was never intended to be a profit center for the company, but it got ridiculous. She mentioned a couple of products Microsoft had put out that (as she put it) customer support got hit very hard on. She said they had the same people working nine hours per day taking calls, never getting to the end of the queue. They could have stayed open 24 hours per day and maybe the queue would have gotten skimpy around five in the morning. Thus they decided to begin PAID customer support. Customers get a certain amount of free support in the beginning and pay for it after that. She said it was a relatively small number of customers who forced them to do that, but the way it had been going, customer support was a drain on the whole company. I was reminded of telco's decision to begin charging for directory assist- ance after how many ever years of free service. It was much the same thing, with a handful of big corporate subscribers who were very heavy users of directory assistance (credit departments, collection agencies, etc) banging away at them so much that they could no longer give it away for free. Anyway, I stand corrected, at least in Microsoft's case. As to the DJ, I still don't know what I think of that idea. The woman said using the DJ was not all that successful since predicting the holding times in the queue was next to impossible. The customer ahead of you in the queue might be gone in thirty seconds or he might be there for thirty minutes. Thanks very much Shawn for putting together the conference. It was quite interesting and informative to say the least. PAT ------------------------------ From: hmweine@PacBell.COM (Howard M.

I experienced the same thing before they upgraded the equipment in the telco. (Oh, this happened to me when the telco offered _only_ CID number delivery, once they upgraded to name and number, the problem stopped.) But as I was saying, I had the same problem of some calls not delivering _any_ information to the caller ID device, and I _did_ pinpoint the roots: If someone calls you on his three way (meaning, he is already on the line with someone, and then flashes and calls you -- the person with the CID) then the caller ID would not receive ANYTHING from the telco (the equivalent of hooking a caller ID device to a line that is not subscribed to Caller ID service). Now that is not entirely true ... let me re-say more accurately: If I speak to someone, and then flash, call another person on my three-way and then flash right back BEFORE it rings on that other person (meaning the first person I was talking to can hear the ringing of the new call), then the Caller ID does not receive the information. However, if I talk to someone, and then flash, call another person on my three-way and WAIT for two rings (or until he picks up) and only then click back to the original call, then the caller ID will show the information. They fixed the bug in the upgraded system, but now there is a new cute bug. Now, when I call my caller ID modem, using three way, and click over to the original call AFTER I see the Caller ID information has been transmitted, it will send the information a second time, so on my screen I will see the same exact call showing up twice ... There is another bug I realized they have, which nobody will probably believe me they have (as it will make many people kinda sweaty), but that is another story. Just to give you a hint: _don't_ give out your credit card number/information if you happen to make a call that goes through my local phone company main office. (And no, it absolutely takes no special rewiring or even a device to do, as I said -- it's a bug in the system...)

PAT] It's not the box, Pat. There are too many bugs in the phone system. If only I lived in Washington DC, I could have made MILLIONS selling overheard conversations of corrupt congressman (without even leaving home OR using _anything_ but a phone line, a phone and my finger). But I value my life too much for that. I rather just overhear funny people talking discretely, believing in the good ol' Ma' Bell to provide them privacy ... Laugh if you want, it matters not to me. [TELECOM Digest Editor's Note: That's amazing. I imagine a lot of the readers are testing it out as they read this ... do you mean to say that I could dial a silent termination number, flash for three way and then dial your number, flash quickly without you getting the ID and then converse with you (and the silent termination line as our third part of it) ... and you'd never see my ID, let alone the privacy indicator or anything else ... hmmm. Please write back again soon and explain the other quirk you found with credit card numbers, won't you? I'm sure a number of readers will want to investigate and repair that problem also.

Yes, I know an octet is a byte, but the PacBell people call 128 bytes an octet (I don't know why). I was erroneously told last week that the packets are 128 bits, but I thought that was too small. I called again, and they said it is 128 bytes. I still don't know why they call it an octet though.

I came late to this discussion, but I think I might have something to add, related to the size of the cellular industry. Let's see, if I did this right, the total cellular industry was estimated to be $11.35 Billion. That's from $454M = 4%. Here are some numbers from my companies annual report, so they must be public info: 2.3 million cellular customers $1.6 Billion (yes folks, with a 'B') revenues That comes to about $700 per year per cellular subscriber. Dividing the $11B total revenue by the estimate of revenue per subscriber I get just over 16M subscribers. We're the second largest cellular provider, and these figures suggest we'd have about 1/7th of the overall market. Since there are nine majors (seven regionals, GTE, and ATT) this makes sense, and confirms the figure somewhat.

It is caused by the fact that manufacturers cannot economically match cell capacities in a series string. If you have a cell that is low in capacity relative to the others in the string (only 1% low is enough to do it) only at the end of discharge, due to the Ni-Cads flat discharge profile, will reversal occur and be a problem.

Modern Ni-cad batteries have a very efficient overcharge mechanism and can be left on charge indefinately without a problem (unless the charger fails). The only time this is not true is if you have the very rapid recharge batteries and charger. Extended overcharge (if even possible with the charger) will damage this type of battery.

I spent this past summer in Moscow and did research in the Russian telecommunications industry, so I know a lot about Comstar from both the technical and business sides. Basically, they are a joint-venture of a British firm (I don't have the name in front of me) and the Moscow City TElephone Network (MGTS). They provide international, national and local phone service at ridiculous rates (though, as their sales pitch goes, the call goes through "first time, every time" a big improvement on the Russian system). They have a sister company in Petersburg called Peterstar, who did a lot of the communications for the Good Will Games. comstar operates two digital switches in Moscow, with a connection to Eutelsat for international traffic. Rates are crazy and support the addage, when there are bodies in the desert, the vultures circle. Installation runs from $250 to $800 with a minimum of $150 per month (not too hard to do considering calls to the US are $3.25 per minute). They operate a payphone service in Russia where for $12 per minute (yes, that is twelve dollars) you can call the USA. The phones take prepay cards or credit cards. Their service is reliable and state of the art, something difficult to find when it comes to Russian phones. There are other similar providers in Moscow, Combellga is Belgian and Sovintel is the American one. I believe Itallian telecomm recently opened Astelit as well. None of them are cheap, they are all joint-ventures with Russian companies (well, the Russian state anyways), but they provide reliable communications that wouldn't be there otherwise. That's a summary; if you have any specific questions, I'll be happy to try to answer. You can call Comstar themselves at +7 503 956-0001.

I very much look forward to a personal sub- scription within the year when I buy my PC for graduate school. Although I am not the most technologically competent person among the readers to your journal, I do manage to comprehend enough to keep me interested in telecommunications. Reading your Digest each day has helped me become aware of the many very exciting developments in tele- communications. Since I have read-only access to Grouptalk, and because I do not have a home computer or access to the Internet itself, I would appreciate it if you could post this question for me: I am working on an undergraduate research paper in Library Technology and I would appreciate any assistance you or other readers can give me. Some theorists have postulated that the library of the future will be a virtual library, i.e. a library without walls, from which patrons wil have full access to materials from their home computers. Is this a plausible scenario? What telecommunications technology will support this? I can read anything posted in response, but if your readers would prefer to send me a personal response they can do that also. Please send responses by snail-mail (my apologies for not being wired): Theresa Arenholz 15 Sgt. Morgan Lane Haddam Neck, CT 06424 All replies will be greatly appreciated and acknowledged, and if there is sufficient interest and responses sent to me by snail-mail I will forward same to you. -------------------- [TELECOM Digest Editor's Note: Theresa, here is your note, and I hope it generates some responses to you. I'd like to receive the replies here if possible so we all can share in the discussion. I think your scenario sounds quite plausible. I can't ever see physical libraries as such disappearing, but we are in fact seeing more and more libraries 'on line', with all sorts of services ranging from simple BBS programs to more sophisticated catalog services, etc. The first library in the world, so far as I know, to have a BBS was here in Chicago at the North-Pulaski branch of the Chicago Public Library. It was 1981, and a simple, very humble beginning. I was grateful to be part of it for a year or so.

I have your definitive answer in my cellular documentation! :) The Ithaca area is in the middle of a large blob around the Finger Lakes listed as "1995 Projected Roaming Area" for The Upstate Cellular Network, operated by RochesterTel Mobile Communications. RochTel Mobile is partners with NYNEX Mobile and Advantage Cellular on the B-side throughout New England; you'll be able to get their Q-Plan service plans. You can get a choice of packages with various amounts of prepaid on/off peak time built in and discounted overage; and as long as you are in NY, VT, NH, ME, MA, RI, or CT, you'll pay $0.65 after taxes for roaming with no daily fee. They have excellent coverage out here and along the NY Thruway, and according to their maps, the Ithaca/Finger Lakes region is the only major dead spot left in their NY system. I'm happy with their service; they're happy to adjust your bill if you find charges you didn't expect or that don't look right. Oh, Call Waiting, Enhanced Call Forwarding, Conference Calling, and ACD are free of charge. RochTel Mobile (716) 777-2700 (The map I have implies RochTel will be the actual carrier, but it might be NYNEX or Advantage. RochTel serves Buffalo, Rochester, Syracuse, Watertown, Massena, Jamestown, Corning, and points inbetween.)

And considering, as you pointed out, the costs of doing it yourself from almost scratch, it might be a lot better to let an established service do it and negotiate for the best terms you can get. Get a short term contract for starters so you can buy some time while you investigate starting your own. I suspect with the proper coordination, you could have something on line in a couple months via one of the established email vendors with which your managment would be quite pleased, and at much less cost -- especially start up cost -- than you could ever swing on your own.

And here is where we see the true folly of ideas like Oppenheimer's: in the case of 1-800-FLOWERS, a trademark is entirely unnecessary, because there can be only one owner of that number in the U.S. phone system. What's really alarming about Oppenheimer's logic, though, is that it would presumably entitle the owner of 800-FLOWERS to also own FLOWERS.COM, "FLOWERS" on America Online, and the use of the word FLOWERS in any other electronic addressing scheme. After all, if prior ownership of an address-name in the U.S. provides for ownership in a completely new domain -- the international telephone market -- then surely a business would be silly not to press for similar reasoning in any other domain (e.g. Internet addresses). And that's not even considering the arrogance of U.S. companies presuming to have priority over non-U.S. enterprises in the worldwide telephone arena.

IS&N 95 - 16-20 Oct. 1995 Call for Abstracts Deadline: April 10th Conference Location: Crete New network technologies and de-regulation of the telecommunications market offers the opportunity to offer communication services to people at unprecedented levels.Justification of the required investment will, however, be determined by the uptake of services by potential users of these services. This conference is concerned with the necessary infrastr ucture to cost-effectively develop, deploy, and manage new and innovative communication services; addressing definition of these services, architectures, engineering processes, methods, tools and techniques. The conference is organised by participants in the RACE (Research into Advanced Communications in Europe) Programme. Aims and Audience: The provision of advanced communication services will have to take place in an environment where a number of technological service and network strands (IN, TMN, mobility, etc.) will have to interwork and, eventually, converge. How and where the advanced services would be delivered in such a diverse environment is a major area of study --- the subject of "Intelligence in Services and Networks (IS&N)". The Conference provides a forum for the dissemination of knowledge and experience in activities relating to the realisation of IS&N systems. It provides an excellent opportunity to submit technological developments to the critical scrutiny of a broad community of systems professionals, managers and users with a view to eventual market development. The Conference programme includes presentations, discussions and workshops, plus keynote addresses by internationally recognised speakers, and is relevant to a broad range of people with an interest in, or responsibility for, the planning, development, engineering, management, provision, and operation of advanced communication services Issues and Scope: The Conference programme addresses issues such as: -IS&N Applications and Required Advanced Services -Usability Factors for Advanced Services -Service Architectures -Communications Management Architectures -Service Management and Quality of Service Management -Security of Services and Networks. -Software Infrastructures -Strategies, Policies and Standards for IS&N Implementations The following questions are to be posed and answered in presentations, discussions and workshops: -What requirements will users place on Advanced Communications Services? -What type of intelligence is required for current and future services and networks and where should it be placed? -Which security concepts and functions are crucial for advanced services -Which emerging technologies are required to achieve integrated IS&N systems, embracing service creation, management and execution? -Will these technologies prove themselves in practice and will they be cost-effective? -What standards need to be defined for IS&N, and do the appropriate mechanisms exist to ensure their timely preparation? -How should the IS&N marketplace be tested to establish service viability? -How can services be configured to meet the needs of particular users and applications? Contributions: Those intending to present papers should submit, by e-mail, an extended abstract (approx. 1000 words) in "flat" ASCII format to the Programme Committee at addresses: conf@postman.dg13.cec.be AND despo@alpha.ath.forthnet.gr The abstract should include the main points of the paper and, where possible, indications of supporting diagrams and references. If desired, additional formatted and printed material (e.g. diagrams) may be sent to the Conference Secretariat. The selection will be made according to the recommendations of a review panel. Those authors whose abstracts are selected will be invited to develop their papers and provide a full typescript of approximatly ten pages of text. The consolidated conference proceedings will be published as a book. Contributors should note the following key dates: Abstracts received by: 10 April 1995 Notification of acceptance: 22 May 1995 Final papers available: 3 July 1995 Camera ready paper received : 30 July 1995 Conference Secretariat: Despina Haralambidou Alpha Systems SA Xanthou Str 78 Tavros, Athens, Greece Tel: +30.1.48.26.014-17 Fax: +30.1.48.26.017 e-mail: despo@alpha.ath.forthnet.gr Organising Committee Chairman: Nikos Karatzas (e-mail: nikos@alpha.forthnet.gr) Programme Committee Chairman: Anne Clarke (e-mail:A.M.Clarke@lut.ac.uk) ------------------------------ From: writchie@gate.net Subject: Re: T3 Framing and Connection Date: 23 Mar 1995 06:21:35 GMT Reply-To: writchie@gate.net In , Phillip Schuman <72510.1164@CompuServe.

DS-3 framing is a bit more complicated than DS-1 due mainly to the need to control the insertion of stuffing bits on the DS-2 streams. I posted the format a few months ago in this group. A DS-3 frame format includes redundant parity over the data bits in the previous frame which is widely used for performance monitoring. The BNC's are normally DSX-3 level signals with a separate connector for each direction. Most fiber equipment provides DSX-3 signals. There are, however, some types of equipment with direct fiber connectors which are internally demultiplexed to the DS3 level inside the box. DSX-3 equipment is often protected 1:1 Hope this helps.

Where to put Q and Z is a matter of some debate. The financial services industry had a de facto standard of putting Q and Z on the 1. Most cellular phones I have seen follow(ed) this standard. It works well, and supports two-stroke key entry better (e.g., 71 for p, 72 for r, and 73 for s). Next time you're at your ATM, try to find the Q and Z. Bet you they're on the 1. PBX manufacturers and voice mail folks wanted a standard they could call their own, so they started putting Q on 7 and Z on 9, where they belonged! ;-) I think all ATT phones now sport these letters in these locations. This configuration makes the most sense for when you don't need a to identify a specific letter, the program just tries to figure out which one of the three you meant. However, it does make life difficult for anyone trying to enter a specific letter. So now things are really confused. Do you assume your callers on a cellular phone (QZ=1), an ATT phone (Q=7, Z=9), or a phone without Q and Z anywhere on the keypad? Additional stickler, assume you are building a financial application, and people will also be using the service on an ATM.

Now that we have name and number (and soon Caller ID with call waiting) I'm wondering if anyone makes a unit that is backlit anymore. I've seen some CIDCO units sold under other names that have a "new call" light (until you review your list) but can't find any actually backlit. I really dislike trying to read LCD's in poor light (or turning on a light just to see it if I'm awakened in the night by the phone).

Lo and behold I could not do it from Australia. I, being a resoureful guy tried AT&T's USA Direct, "I am sorry you cannot make calls to 700 or 500 numbers on this service." She put me through to an AT&T Business Office for free. The guy there said "I have never heard of a 500 service". Tried talking to OPTUS (the second long distance carrier here. Owned 50% by Bell South) and they said they would investigate it. They rang back and said quoting "an AT&T source" that "service is restricted to US only". I tried again later in the day asking for a supervisor and got the same story. I cannot dial this number via Telstra, (the old government owned monopoly). The jury is still out on this one. They take a few days to come up with excuses usually. My question to you is, do you have any AT&T document that acutally states the service is acessible outside the US? It is not for me. I know it can; I would like to shove this up the relevant phone companies' noses. Regards, Serge Burjak [TELECOM Digest Editor's Note: I decided to call the 500 people now and find this out once and for all. The woman immediatly answered me saying it can *always* be done through USA Direct; whether or not it can be dialed direct otherwise (as an international call) from other countries depends on the country and the telecom admininstration. But she did emphasize it can ALWAYS be done through USA Direct. So I read her your email. She was quite familiar with OPTUS and Telstra; she recognized the names immediatly and said she did not know their specific policies but that either *should have* referred you to USA Direct even if they could do nothing else. We got back to USA Direct and I quoted your email to her about getting connected to the business office and the man telling you he never heard of 500 service ... she also found a note on my account saying that you had called and reported the problem yesterday and a specialist had gotten involved. Then she said, "I want to try something ...". She put me on hold and used another line to call USA Direct herself and asked to be connected to my number. The operator told HER it could not be done. !! She talked to a supervisor at USA Direct who said the same thing ... and then to a manager at USA Direct who said 'well you are supposed to be able to do it ...'. She came back to me and said "those people are confused." She said the marketing department at AT&T specifically planned 500 service for use from anywhere in the world to anywhere in the world, albiet via USA Direct when international direct dial was unavailable. I told her about getting the call at 7 AM my time from the guy in New York with AT&T 'international' who had never heard of 500 service, and the (now) three other calls I have received from an AT&T employee (a woman who called one day and said she had been given 500-677-1616 as a 'test number'), a Bell South service representative who was trying to help a customer, and someone from British Telecom who reached me on my 708 number to ask some questions. Regards the ignorance of AT&T people about 500 service, she said, "that's incredible ...". I asked her why in the world all AT&T employees had not been made aware of this new program; after all, it is a very good service. She said that all employees got written notice. How did she know? Because it was printed on their paycheck, and they all get paychecks, and they all look at what the paycheck says ... ... not only that, she said, it was offered to all employees under special terms and many employees had called to sign up. It was mentioned on company internal 'newsline' messages. She said she still had her own paycheck stub with the announcement offering 500 service to employees. Even if all employees did not know that much about the offering, you'd think affected employees (i.e. traffic department people, service reps, etc) would know, wouldn't you? Yes, she said, you'd think so ... After finishing with her I tried another experiment of my own from this end. I dialed the double zero operator (in the USA, zero alone defaults to the local operator, and zero zero alone defaults to the operator for the long distance carrier, in this case AT&T) to see what she had to say. "Assist in dialing please on a no ring, no answer, 500-677-1616 ..." meaning I had dialed it and could get no response from the network. Her reply, "There is no such area code as 500, that's why your call would not go through." Uh-huh ... tired at this point and wanting to get back to sending out this issue of the Digest I thanked the operator for her court- eous and thoughtful response and disconnected. We'll see what happens in a few days. I'm told 'marketing' will get my case history as an example for their use.

Just a note, perhaps a nit -- my understanding of the term baud is that it refers to the rate of modulations or signal changes per second, rather than the number of bits per second. In other words, the baud rate is always equal to or less than the bit per second rate. Using common standards, the 300 baud modem transmits and receives data at 300 bits per second; however, a 14,400 bit per second modem operates only at 2400 baud. (it might be a different baud rate - the point is that there is no such device as a 14,400 baud modem) Someone with more technical expertise can field this issue better than I, but I am quite sure that "baud" is one of the more misused and misunderstood terms in telecommunications.

I would suggest that you invest a lot of time into putting each of the companies on the Internet and that you use the Internet commercially as the vehicle to for inter-office communications. What with the advent of the Internet Phone and Video Conferencing plus the fact that security problems are being overcome, why pay for leased lines.

From my wife's office you get a recording that says the call can't go through and an operator won't be able to place it either. The one outside person I've given it to so far wasn't able to dial it from his work, called information -- they'd never heard of it -- talked to an operator, who talked to a supervisor who thought maybe it was an ATT thing and finally was told to dial ATT and was able to get through to me.

You might want to make sure your inability to reach 0-500 from Centel territory is a problem of Centel and *not* something to do with the switchboard at your company. If you can use a nearby payphone also on Centel and get through then your switchboard is blocking 0-500 for some reason. If the payphone or some private phone in Centel territory won't let you through either then call their business office and ask why not. 1-500 won't get out through a Centel payphone anymore than it will from an Ameritech pay phone simply because there is no number to bill, and they are not accepting coins as payment. You did not mention if your wife was on the Centel or Ameritech side of the northwest suburbs; if she is on the Ameritech side, then that's one more central office where the translations were loaded incorrectly. When I finally got someone in repair to listen to me, they fixed our office here in Skokie the same day, several hours later. Regards your friend at his office, try to eliminate his company switchboard as the source of the problem. If it is blocking the calls, there is really nothing telco or AT&T can do. If he has access to a payphone and/or private line *in the same immediate vicinity preferably out of the same central office* and still cannot get through at all, then there is another telco problem.

They also have different directory attributes, including longer file names and attributes called the "type code" and "creator code" which tell the operating system what application to launch and what icon to display. There are three competing standards (and some proprietary solutions) for representing this information on a non-Macintosh computer; the most common of which is MacBinary II, which originated on CompuServe's MacDev forum. Another common work-around is to compress the files using any of the standard compression packages; the result is a plain, data fork only, file. You then have to hope that your decompression software is smart enough to ignore the missing type and creator codes, but increasingly, they are. As somebody already wrote in, the =easy= solution is for you to =somehow= obtain a copy of StuffIt Expander 3.5.2. You can buy StuffIt Deluxe at any software shop; that way you get both StuffIt Expander and DropStuff. You can pick up StuffIt Expander and the annoyanceware version of DropStuff for $2 or so at any Mac user group meeting, I suspect. Or you can download it from just about any bulletin board or online service ... to your Mac. If you're determined to =only= use the modem on your PC, you can get baroque and then use a null-modem cable to connect your PC to your Mac, and use =terminal software= on both ends to transfer the file; the Mac will recognize an incoming MacBinary file and decode it. But by the time you screw around with the cables, you might as well move the modem this once. Once you get StuffIt Expander installed on your Mac, if you have System 7.x you can drag and drop just about anything, or even whole folders of anything, onto StuffIt Expander's icon and it will figure out what archive format was used on each file and unpack it all for you. Oh, and you'd rather get StuffIt Deluxe or put up with the shareware notices in the shareware version of DropStuff, by the same company; once it's installed, StuffIt Expander will not only unpack StuffIt (*.SIT, *.SDT) archives, MacBinary (*.BIN) files, and BinHex (*.HEX and *.HQX) files, but also almost everything else including Arc (*.ARC), PackIt (*.PIT), PKZip (*.ZIP), Compactor Pro (*.CPT), UUEncode (*.UU), Tar (*.TAR) and just about everything else I've run across. In fact, if somebody compressed a MacBinary and then uuencoded it, it'll do all three passes in one step. I have no connection to Aladdin Systems or to Ray Lau except as a satisfied customer. J.

Date: Thu, 23 Mar 95 12:49:00 PST Original post from jwarren@well.sf.ca.us (Jim Warren) > "Mark your calendar. In April, 1995, Caller ID will be a 'done deal,' > nationwide. You may or may not have Caller ID service from the phone > company today. But in April, every telephone company coast-to-coast > will be required to offer it, by law. This is an interesting "interpretation" of the FCC Order. But, NO, the FCC did NOT mandate that Caller ID services be made available everywhere effective 4/12/95. The FCC DID state in their Order on Calling Number Services that if a telco is "SS7-capable", they must transport Calling Party Number (CPN). With SS7 installed, this alone does not make a telco capable of CPN transport. The Order as originally written (3/94), made other assumptions that were not correct or technologically feasible. As a result, the FCC stayed the portion of their Order related to blocking. The original Order specified that on interstate calls, the telco could NOT offer Per Line Blocking. However, most states require Per Line Blocking as well as Per Call Blocking. The FCC only wanted consumers to have Per Call Blocking (using *67). The problem the telcos faced was that they were unable to process interstate calls in a different manner than intrastate, and as a result, would be either violating state or federal regulations (they were contrary in most states). The problem was exaggerated in the cellular environment, where a "local service area" can span multiple states. Recently, McCaw deployed the first true Caller ID service on a cellular network in its Oregon operation (Cellular One). In Oregon, digital (TDMA) subscribers are enjoying this service and both Per Line and Per Call blocking options are supported.

They gave me a typical rundown of thier services. $10 setup, $4 a month, $.21 per minute non-peak, $.28 on peak. This is fine and dandy. They also informed me that it would not be a problem that the 800 number points to my local rotary service. Cool. What is happening is, I am running a Internet Service provider, and naturely, it would be of great benefit if I could expand out to areas that don't have internet services (but still deliver good rates). With the rates I described above, I will have to charge about $16.00 bucks a hour just to break even on the call, not to mention the service fees. That's a little much; I was hoping from something around the $3-5 dollars hour. I have heard that there are third party 800 suppliers, and would like to look into them. Does anyone have any comments on these third party services? How about some good services to look into? With the demand that we will carry, it would seem that we could find a cheaper method, which I could pass on to my users. [TELECOM Digest Editor's Note: Well, you can get 800 service alot cheaper than 20-25 cents per minute -- even from the big three -- but generally you need to commit to purchasing *a lot* of it each month. If you can produce big time traffic for the carrier, I've seen 800 service priced as little as $6-7 per hour (10-12 cents per minute with six second billing, etc) delivered on T-1. Maybe you can get it even cheaper than that, but the literature I've seen always talked in terms of $10,000 - $30,000 worth of traffic per month with a commitment for at least a year, sometimes longer. The price is a bit higher than above, but then once you cross a certain threshold -- and make prompt payment each month -- discounts kick in which bring it down to the above range. The so-called third-party people I've seen all talk in terms of 20-25 cents per minute; they are getting it cheap enough but want their cut of the action also. You did not mention the volume of traffic you anticipate, or how far out you want to stick your own neck waiting for the traffic to materialize -- if it does -- or how much cash you want to have tied up each month after you pay the carrier and wait for your customers to pay you, but if you pull it off right, yeah, I would say you could get 800 very cheaply and on good terms such as six second billing.

Senator Slade Gorton (R-WA), who had cosponsored S. 314 with Senator James Exon (D-NE), proposed the amendment in Exon's absence. It was adopted on voice vote as an amendment to the Telecommunications Competition and Deregulation Act of 1995. The amendment would subject on-line users to scrutiny and criminal penalties if their messages were deemed to be indecent, lewd, lascivious or filthy -- all communications that are protected by the Free Speech Guarantees of the First Amendment to the United States Constitution. Although protecting children from pornography is its most often cited rationale, this is really a "bait and switch" with your rights at stake. Note that the amendment in fact goes way beyond child pornorgaphy. It's like the opponents of TV violence who first said children should be protected and then made "Murder She Wrote" with Angela Landsbury their number one target. Or like the censors who banned "Huckleberry Finn," "Where's Waldo?" and even Webster's Dictionary (it has "bad" words in it, after all). The Exon/Gorton Amendment would invite active interference in the basic speech of everyone using any telecommunication device -- simply because some government bureaucrat somewhere thought the speech was indecent or lascivious. All senators on the committee had been informed that the Exon/Gorton amendment would violate the Constitution, assault the liberties of net users, stifle development of new technologies (many of which offer greater choice and control by all users -- including parents), and spawn expensive litigation -- while not succeeding at reducing access by children to pornography. A coalition of civil liberties organizations -- including the ACLU -- and numerous commercial companies warned against adopting the Exon/Gorton amendment, which originally would also have made all online service providers (in fact, anyone transmitting an offensive message) criminally liable. Some commercial companies offered Exon and Gorton language exempting themselves from liability while still letting their subscribers be prosecuted. Today Senator Gorton said that the amendment had been modified to exempt those merely "transmitting" the message. The amendment would, however, still cover anyone who originates a message deemed indecent, lascivious etc. WHAT YOU CAN DO: 1. Contact the senators from your state, and all senators on the Commerce Commitee expressing your disappointment with Thursday morning's action. Thank Senate Commerce Committee Chairman Larry Pressler (R-SD) for not including the Exon/Gorton amendment in his proposed bill, and urge him to support action on the Senate floor to remove the anti-cyber amendment. 2. Contact your online service providers and ask them what they have been doing about this Exon/Gorton assault on your liberties. Some providers are still standing up for your rights; others may not have.Urge them, not to support any legislation that protects them, but violates your free speech rights. Urge them to oppose the modified Exon/Gorton amendment. 3. Contact all the other senators and urge them to support deletion of the Exon/Gorton amendment when the bill comes to the Senate floor. 4. Stay tuned for further information and action items for both House and Senate. The American Civil Liberties Union is a nationwide, nonpartisan organization of over 275,000 members. Now in its 75th year, the ACLU is devoted exclusively to protecting the civil liberties guaranteed by the Constitution and the Bill of Rights, whereever these liberties are at risk -- in a bookstore, in school, on the street, in cyberspace, wherever. The ACLU does this through legislative action, public education and litigation. ---------------------- Send your letter by e-mail, fax, or snail mail to: Senator Larry Pressler, S.D.

Defective phones can be fixed with a bit of epoxy. It may take a few treatments, but eventually the equipment starts working as God and Alexander Graham Bell intended. I guess one won't be able to use a modem with these phones either. I guess you can see why I'm posting this anonymously! [TELECOM Digest Editor's Note: Yeah, I guess I can see why you are posting it anonymously. Either the equipment starts working correctly or else its owners take it out entirely, eh? So the ninety percent of the American public who has never heard of voicemail, and the ninety-five percent or so who don't have it or need to retrieve anything from it get punished as well by having the one payphone in their neighborhood which formerly had been operated by Bell replaced by a COCOT. I can see your point though. It does make you kind of angry.

The 970 lines are still used in the NY Metro area. However, dialing 970-XXXX from within the 516 NPA as opposed to dialing 1-970-NXX-XXXX is the same as the difference between dialing 334-XXXX and 1-334-NXX-XXXX. It's not so much that the switches need to be re-programmed as the PBX's that now block 970 calls. Does anyone know if there is a method to the madness in selecting the new NPA's? Originally it was based on the number of 'pulls' and the last few in the N10/N1X series were whatever was left. It almost seems random. You would think that they would stay away from 97X and 5XX, given the number of premium-charged services with similarly numbered prefixes. Sheesh! Stan [TELECOM Digest Editor's Note: *Is there* any method to the madness now? Does anyone know of any formula pr process used to select the numbers being assigned as the new area codes? We all know how 212, 213, 312, 313 and others in that range came to be selected: in the rotary dial era those were the ones with the shortest number of 'pulls' and they were assigned to the major cities on the assumption most calls would go to those places. What about now? Is it just random, or do telcos request certain codes in the same way subscribers request vanity numbers?

I assume you mean the premium 970 exchange present in some NPAs, where it is similar in function to the 976 exchange. There's nothing preventing any NPA from continuing to use 970 as an exchange. Eight-digit dialing (e.g., 1-970-XXXX) went away earlier this year in those places that required it, so local 970 numbers now have to be dialed as either 970-XXXX or as 1-NPA-970-XXXX. Ask your local telco to find out which dialing plan applies to your area.

So where is it and how is it dialed? There should NOT be any ambiguity. For one thing, the history file, which I have continued to update, has dealt with changes in dialing instructions which were made necessary by the coming of these generalized area codes. Long distance to points in the new 970 area would be 1-970-xxx-xxxx, even within that area code.

Can the technology (in this case available bandwidth) support the demand? In some US markets, we've seen that -- without further multiplexing -- PCS (GSM) can support 20% of the POPs (200/1,000). There should be a ceiling there (at least near term). 2. The "80% interesteds" are just that ... interested. But, adoption is another story. Take into account TALC (Technology Adoption Life Cycle) which suggests a 1-2% share initially (innovators), another 10% subsequently (early adopters) and then, with a herculean effort, migration into mainstream markets (at best...another 30-40%). Prior to migration into mainstream markets there will be a big consolidation of carriers (just to garner the resources & bucks necessary to successfully stimulate adoption among mainstreamers which are classically "attacked" one market segment at a time). 3. I think the Swedish statistic (9.8%), without seeing how collected/analyzed, etc. but from a structural perspective, is the most realistic. 9.8% would assume 100% share of innovators and most early adopters. Mainstreamers are always a gamble but will jump in at some point. They are risk averse, however, and while the time line moves fwd, innovators and early adopters may have already jumped into a newer technology. 4. In the U.S., our "rule of thumb" for PCS is a 10-15% adoption rate near term (eg., three years). After that, god only knows. I hope this information helps.

Ron Conners, director of the numbering plan, said at the Supercomm '95 conference in California that many PBXs have not been upgraded to allow the new Alabama 334, Washington 360 and Arizona 520 area codes to be reached. In most cases, users have complained to the serving local operating company when they should be complaining to their PBX managers. Apparently, switches manufactured before 1993 are the ones that largely don't support the new area codes without upgrades. PBX managers are resisting upgrading their switches, the story says, because they don't want to spend the money and because they feel that the new area codes are in remote areas of the country that their users would not call much anyway. "People are in denial," said Conners. The story notes that customers in Alabama and Washington caused an "avalanche" of complaint calls because their "phones suddenly went silent." I can't explain this since we are still in the permissive dialing period for these places. US West, which serves most of Washington, announced that it would begin assigning duplicate prefixes in the 206 and 360 area codes TWO WEEKS after permissive dilaing ends because the shortage of numbers is acute. The story reviews upcoming or in-progress area code additions: Colorado, existing code 303, new code 970 Texas, 713, 281 Florida, 813, 941 Connecticut, 203, 860 Illinois 708, 630 Virginia, 703, 540 Tennessee, 615, 423 Georgia, 404, 770 South Carolina, 803, new code not given, but we know it's 864 Missouri, existing code not given, but I'll bet it's 314 Oregon, 503, new code not given Florida, 904, new code not given For the remainder of the century, Bellcore predicts new area codes in: Ohio, existing code not given, but I'll bet it's 216 Minnestoa, existing code not given, but I'll bet it's 612 California, 619 Texas, 817 Texas, 210 California, 213 Louisiana, 318 British Columbia, 604 Missouri, 816 plus ten more splits beyond these before December 31, 2000.

The PBX guys denied it, refused to deal with it as long as they could, and made service very difficult for many users. I recall a case of a large store in downtown Chicago for whom I did some part time work on a contract basis for quite a few years. I reported the inability to get calls out to such an exchange. I reported it various times. The guy who took care of the PBX would do nothing about it ... said there was 'no reason to call that exchange, anyway'. I had voicemail at the time on that exchange, so my answer was to delete any and all references to my home phone number from the records of those who needed it, and leave my voicemail/pager number instead as my contact instead. I guessed it would be just a matter of time ... sure enough about a month later they wanted to call me one day to ask for something. Three different people in the department spent the better part of two hours trying to reach me. They finally gave up and went to a payphone nearby. The next day the PBX had been adjusted.

For Release 9:00 A.M. March 10, 1995 SAN CARLOS ANNOUNCES INTERNET REAL ESTATE GUIDE On Line Restaurant Guide Also Enhanced SAN CARLOS, CA -- March 10, 1995 -- The City of San Carlos announced today a new service on its Internet server called "The San Carlos Real Estate Guide." This is an area on the Citys "San Carlos On Internet" service that provides information on housing projects being built by the San Carlos Redevelopment Agency, property available for lease in the San Carlos portion of Redwood Shores for two restaurants, a point and click guide to houses for sale in San Carlos and information on real estate agents in San Carlos. The information in the San Carlos Real Estate Guide on City housing projects has been compiled by the San Carlos Redevelopment Agency. The other information has been taken from material placed on the Internet by local realtors from Coldwell Banker, Cornish & Carey and Re/Max. By combining the information in an easy index, San Carlos residents and firms and potential San Carlos residents and businesses can quickly find out about housing and commercial properties in San Carlos. Mayor Kevin Kelly said that "San Carlos has received many calls and letters complimenting us on our vision to be one of the first cities in the country to use the Internet to keep the public informed about City services. The next step in this process is to use our presence on the Internet to make businesses in San Carlos more successful. The new San Carlos Real Estate Guide on the Internet is a great step in this direction." City Manager Michael Garvey noted that "We have been offering businesses in San Carlos who are on the Internets 'World Wide Web' a free listing on the City Internet Web area. To date, four San Carlos businesses -- Bay Area Model Mugging (womens self defense training), Friendly Software Store, Library Solutions Press and Salvatores Restaurant -- have taken us up on this free offer. Opening the San Carlos Real Estate Guide provides a similar opportunity for realtors and property owners in San Carlos. Im looking forward to seeing how this program helps stimulate the business and real estate markets in San Carlos." Assistant City Manager Brian Moura added that "Our San Carlos on Internet project is now attracting over 1,000 users and over 3,000 document requests per month. With that much activity, adding information about firms doing business in San Carlos is a natural extension of our Internet project and we trust that San Carlos citizens and other users of the Internet will find these new services of interest." San Carlos Restaurant Guide on Internet Enhanced ================================================ The City also announced that it has enhanced it's on line guide to San Carlos Restaurants. The guide now includes reviews of eight San Carlos restaurants, an index to the on-line edition of Salvatores Restaurant (this features the lunch and dinner menu at Salvatores) and the new Internet ordering service at Cafe LaTosca where users of the Internet can now order authentic Italian dishes from this popular restaurant in downtown San Carlos simply by calling up an on-line menu and filling out their selections. Note: The City of San Carlos on Internet information is available on the Internets World Wide Web service. This information can be accessed through any Internet service provider or through the Prodigy dial-up service (using the Jump words "WWW" or "Web").

In other words, > the baud rate is always equal to or less than the bit per second rate. Modulation protocols use phase and amplitude modulation to encode a certain number of bits (i.e. two, four, six, etc.) per baud symbol. A CCITT V.22bis (2400 bps International Standard) modem sends four bits per symbol and 600 symbols per second to achieve its speed of 2400 bits per second. The V.32 modem sends four bits per symbol and 2400 symbols per second to reach its speed of 9600 bits per second. The V.32bis modem sends six bits per symbol and 2400 symbols per second to achieve 14.4K bits per second. Thus, higher digital computer speeds use increasingly complex modulation protocols for the same symbol rate. Loop symbol rate is the baud rate that occurs on the physical loop, analog side, of the Public Switched Telephone Network.

Bye, bye, Ma Bell, why did you die? We get static from Sprint and echo from MCI, "Our local calls have us in hock!" we all cry. Oh Ma Bell why did you have to die? Ma Bell why did you have to die? Back then we were all at one rate, Phone installs didn't cause debate, About who'd put which wire where... Installers came right out to you, No "phone stores" with their ballyhoo, And 411 was free, seemed very fair! But FCC wanted it seems, To let others skim long-distance creams, No matter 'bout the locals, They're mostly all just yokels! And so one day it came to pass, That the great Bell System did collapse, In rubble now, we all do mass, The day... Bell System... died. So bye, bye, Ma Bell, why did you die? We get static from Sprint and echo from MCI, "Our local calls have us in hock!" we all cry. Oh Ma Bell why did you have to die? Ma Bell why did you have to die? I drove on out to Murray Hill, To see Bell Labs, some time to kill, But the sign there said the Labs were gone. I went back to my old CO, Where I'd had my phone lines, years ago, But it was empty, dark, and ever so forlorn... No relays pulsed, No data crooned, No MF tones did play their tunes, There wasn't a word spoken, All carrier paths were broken... And so that's how it all occurred, Microwave horns just nests for birds, Everything became so absurd, The day... Bell System... died. So bye, bye, Ma Bell, why did you die? We get static from Sprint and echo from MCI, "Our local calls have us in hock!" we all cry. Oh Ma Bell why did you have to die? Ma Bell why did you have to die? We were singing: Bye, bye, Ma Bell, why did you die? We get static from Sprint and echo from MCI, "Our local calls have us in hock!" we all cry. Oh Ma Bell why did you have to die? -------------------------- [TELECOM Digest Editor's Note: As always, thank you Lauren. This Digest began in the summer of 1981; when there was a "Bell System", and when most people had never heard of MCI or Sprint -- not even some of our very early readers here. There was no such thing as custom calling or ESS; issues of the Digest in the early to middle 1980's talk about things like the beginning of cellular phone service in 1983, the beginning of new long distance competitors like MCI and Sprint, and how Electronic Switching -- still a rarity in the early 1980's -- was the phone service of the future, with such amazing things as call waiting, three way calling and call forwarding. Debates here in those days covered topics like whether or not there was such a thing as caller-id or if it was just the figment of some people's imagination. TELECOM Digest is the oldest continuing e-journal on the Internet, and those of you who have been here since the beginning know we have covered a lot of ground over the years. In those days it was easy; today it is a lot harder, which is what makes your support all the more appreciated. You know what needs to be done, and as always I thank you. Do have a great weekend!

The reality behind it is the National Information Infrastructure, the intent of which is to promote advantages to American business through advanced technology. A number of actions, promotions, bills, and proposals are said to be related to the NII; the most frequently cited is "The High-Performance Computing Act of 1991". (It is one of the ironies of this work that the author has chosen to make his home in Amsterdam.) This book is an opinion piece, told by a professional "gee-whizzer", full of verbiage and vendor promotions, signifying nothing. The author introduces the book by suggesting that it is best read as nine magazine articles. It certainly doesn't have enough structure for a book: even the individual chapters are undisciplined and disorganized. In common with most of those who rhapsodize over the Information Superhighway, Otte has very little idea of what he wants it to be -- just exciting, and high tech, seems to be enough. For those who have any professional background in the broader field of information technology, there will be nothing of any interest here. Ah, but what of the poor "struggling masses"? There isn't much for them, here, either. Chapter four, on "Computing Tools", is an extremely simplistic introduction to PCs and peripherals. "Multimedia Online Services" is a flat-out advertisement for CompuServe, America OnLine and Prodigy. Errors abound, and it is *quite* clear that this author does *not* have a solid grasp of technology. The need for "repeaters" on long distance phone lines would be eliminated if they would just use EtherNet (maximum run length, five hundred metres). PDAs (Personal Digital Assistants) are predicted to be shipping "in volume" by the time the book sees print. XCOPY is a backup program. Multimedia is hyped for eighteen pages -- and then Mosaic is dismissed in half a paragraph, as a "front end" for the Internet, much like WinCIM for CompuServe. I could, very easily, go on. No, I can't even recommend it for newbies. This presents a barely informed, distorted, and "blue sky" view of future technology. copyright Robert M. Slade, 1995 BKINFSUP.RVW 950224.

The trademark is *unnecessary*? Is that a legal opinion? Regarding the U.S. phone system, if we are discussing a cyber-distinction in the United States, you help make my very point. 011 800 FLOWERS and 1 888 FLOWERS are both designed to co-exist in the United States with 1 800 FLOWERS. Now, I'm not familiar with your hometown of Ventura, California. But I can tell you that if there were more than one Fifth Avenue, or Madison Avenue, or Park Avenue, in Manhattan, or duplicated addresses on those avenues, their real estate value would be in a shambles. That value is not a *false* or arbitrary value, but rather is based on real market activity. They are prime magnets for business activity. So is 1 800 FLOWERS.

I've said it before -- I'll say it again. 1. U.S. companies own U.S. brands. European companies own their brands. There is no arrogance there. 2. The vast majority of the direct marketing business - the very behavior of direct phone response - is a U.S. cultural behavior. That's why there are 4 mil + 800 numbers in the U.S., and barely 150,000 throughout the rest of the world. It is appropriation of this existing-behavior, dollar-spending, comparatively "wealthy" marketplace that makes U.S. marketing numbers and brands desirable to non-U.S. companies at all. Otherwise, grandfathering of U.S. 800's would be a non-issue -- a practical request to be granted with no fuss or debate. They wouldn't want 'em if they wasn't worth something. Get it? Judith J. Oppenheimer, Producer@Pipeline.com Interactive CallBrand(TM) ------------------------------ From: victorp@omega.lncc.br (Victor Prochnik) Subject: Outsourcing of International Telecom Services Date: Fri, 24 Mar 1995 19:14:19 GMT We have just started a research project (30 man/month) on the demand of large Brazilian and multinational firms for global telecommunication services and their interest in outsourcing this services. Suggestions of publications, unpublished dissertations, case studies or market studies on this theme are most welcome. We are also interested in mantaining contact with people working in this or similar areas. The research project is the following. RESEARCH PROJECT ORGANIZATIONAL CHANGE AND TELECOMMUNICATION SERVICES DIFFUSION IN BRAZIL Victor Prochnik Industrial Economics Institute Federal University of Rio de Janeiro E-mail: VICTORP@OMEGA.LNCC.BR The aims of this project are in the first place to identify the demand perspectives for global telecommunication services in large enterprises operating in Brazil and in the second place to access the degree of interest of these corporations in outsourcing its international telecom networks. In this project, a greater demand for global telecommunication services is not strictly seen as a result of international commerce growth and greater intensity of financial flows between Brazil and the rest of the world. Our preliminary hypothesis is that another important determinant of demand can be found in the process of organizational change toward new models of network structuring within an expanding globalization process. The adoption of new corporate internal structuring and external relations (industrial automation, groupwork, quick response etc.) requires an increased use of new telecommunication services. In fact, the lines of causality are bi-directional as the introduction of new services also demands organizational change. It is also often observed that such an interplay between corporate change and telecommunications has unexpected consequences. Devised applications not before imagined become intensively used, provoking unplanned changes in corporation organisation. In order to follow this line of investigation, the research team will try to associate new organizational forms or technologies and their requirements in terms of telecommunications services. Following this interdependence scheme between entrepreneurial activities and the respective use of telecommunication services and, at the same time, having collected information on the firms modernization plans, it will be possible to discuss the demand evolution in telecommunication services. In this respect, one of the major worldwide discussed trends is the outsourcing of these global services. No one knows for sure, however, the extent to which large corporations are willing to outsource their international telecom operations. Managerial decisions may depend not only on price and availability of services but also on strategic considerations, stage of firm modernization, economic sector of activity etc. To discuss this matter is the second objective of the project. The research team wil try to discover which applications and services are more prone to be outsourced and why. ------------------------------ Date: Fri, 24 Mar 95 17:32:50 EST From: Tony Harminc Subject: Re: Your 500 Number and International Access > [TELECOM Digest Editor's Note: I decided to call the 500 people now and > find this out once and for all. The woman immediatly answered me saying > it can *always* be done through USA Direct; whether or not it can be > dialed direct otherwise (as an international call) from other countries > depends on the country and the telecom admininstration. But she did > emphasize it can ALWAYS be done through USA Direct. Sigh. One of these days is it possible that AT&T will wake up to the fact that the largest volume of US telecom traffic with any foreign country by far is with Canada? There is no AT&T direct service in Canada. (Who would want such a thing is another question -- generally the Bell Canada operators seem at least as helpful and friendly as the AT&T ones.) AT&T has been advertising that 800 CALL ATT works in Canada, however (again, I have no idea who wants it). So just now I tried it: 1 800 CALL ATT 1 Ring (definitely was not 'AT&T How May I Help You?') Me: Hello ? Operator: AT&T - How May I help You? M: I'm having trouble reaching a 500 number and I understand you can connect me O: No - we don't do 500 calls. M: The owner of the number I was trying to reach was just talking with an AT&T manager and was told that you *do* connect to 500 numbers. O: Just a moment - I'll connect you to mbftmmbf .. Ring Ring , O: AT&T - How May I help You? M: I was talking to another operator who was going to find out if you can put my 500 call through. O: Sure - we do 500 calls - what number? M: 500 677-1616 : AAAA TTTT and TTTTTT! If you have a TrueConnections PIN, enter it now... To charge your call to a calling card, press 0 then pound (sic). I press 0 then # and AT&T immediately hangs up on me. (No this was not my end hanging up - I use the # key all the time on 800 and other calls.) So the bottom line is: even if they educate their operators, speed up the 8 minutes of ringing at some unknown place, and avoid hanging up on the customer, it seems that to reach a US 500 number I am going to have to dial an AT&T operator, ask for the number I want, charge it to some kind of calling card (will they take my Bell Canada card?), pay some unknown rate that certainly will not take into account my LD discount plan with the carrier I use and will probably include a calling card surcharge. In other words, just about the speed and convenience of placing a call from Toronto to Chicago in 1950. PAT, if you or other business people or individuals are seriously interested in any sort of international business, I advise you to avoid this service like the plague. Why on earth does AT&T have to use a bizarre, undialable area code instead of simply implementing a local prefix for this kind of remotely variable call forwarding, as Bell has done here ? They would just assign you a 312 (or 708 or whatever number) and pipe it to the variable call forwarder menu. This is the way it's done here - all 416 410- numbers are part of such a service. This way I would know from the area code whether I am paying for a call to Chicago or Hawaii, would have my usual discounts, and be able to dial it direct. Yeah, I know: local politics probably prevent AT&T from using such a prefix.

If you divide 1MB by 128 you should get 8192. Multiply that by 0.005 and you get around 41 cents per MB. This is how it should work out if the CCITT Recommendation X.25 is followed.

Pat is absolutely right about the average telecom telemarketer and their base of knowledge. Very few 'hone company' rreps have any technical understanding of their products because they generally receive only the most minimal training. This does not make them inferior creatures. I've done my little tech overview classes for reps all the way from London to Los Angeles and have consistently found them to be enthusiastic to learn and appreciative of the chance to do it. The common problem they face (in my opinion) is lack of commitment and support from the higher levels of management to provide the necessary training. I cannot tell you how many times I've had managers tell me that their people do not need fundamental understanding of technical products in order to sell them. Others who have not said this, instead tell me their people already know the fundamentals. I have not found this to be true even in the most 'bleeding edge' telcos. It's the density of the management that creates most of the problems that the reps display when talking to their customers. Unprepared, the reps then attempt to make a living at selling what they don't understand. I too try to cut these folks a little slack. I've looked many of them in the eye and seen myself looking back. Do not muddy the waters around you, you will need to drink it later.

The system is in it's eigth revision and has been used for more than five years. The product will support I believe 10,000 mail boxes and use 2/4/12/24 line cards. The software will support 32 lines of simultanuous usage. It contains all the features of call Paging, Message Notification. Since the system is in wide use the manual and tech support must be good. If you need a demo of this product you might want to call 214-250-4115. This is a bbs number. The file is in the demo directory and is called TES 8.0. This software is identical to VIcki and Verbatim. If you have any question you also might want to try Alliance Systems, Inc.

Paul Hanson ------------------------------ Date: Fri, 24 Mar 95 22:30 CST From: Neal McLain Subject: New Area Code Assignments A recent issue of TELECOM Digest raised a question about how "new" (since 1/1/95) area codes are assigned. A partial answer certainly has to be this: an area code and a central office code can't be the same. And, if at all possible, an area code shouldn't be the same as any nearby central office code in any adjacent area code. Consider how these requirements affect the selection of the new area code when an existing area code is split: - Avoiding a conflict with any existing central office code means that the new area code must be selected from the list of presently-unused central office codes. That list is likely to be fairly short: if an area code needs to be split, it's already running out of central office codes. - Avoiding a conflict with any existing central office code in any nearby community in adjacent area codes makes that short list even shorter. A case in point: the 205/334 split in Alabama: - 334 is not used as a central office code anywhere in Alabama. Thus, there will be no 205-334 or 334-334. - With one exception, 334 is not used as a central office code in any nearby city in any adjacent area code: 404-334 doesn't exist; 601-334 is in Greenville; 615-334 is in Decatur; 706-334 is in Ranger; and 904-334 is in Tallahassee. - The one exception which proves the rule: 912-334 is in Georgetown, Georgia, right across the Chattahoochee River from Eufaula, Alabama. This will no doubt cause some confusion for the 900 or so residents of Georgetown. That confusion notwithstanding, it seems obvious that Bellcore and the local telephone companies went to considerable effort to select the code which would cause the least amount of confusion.

An important part of the telecommunications features of Windows 95 is the inclusion of a database of telephone dialing procedures for all countries in the world, to make it easier for applications to dial calls without each application needing to prompt the user for such information. We'd like for this database to be as accurate as possible at the time the product ships. I've attached a condensation of the database below. The first column is the country code. The second column is the "long distance prefix", or what you dial before a city code or area code if you're dialing between cities in that country (a dash means that country has an integrated nationwide dialing plan that doesn't use city codes). The third column is the "international prefix", or what you dial before a country code when dialing to another country. I'd appreciate it very much if you would check this information for consistency with what you know is currently being used in your country and other countries with which you are familiar. Also, if you know of planned future changes in this information, it would be great if you'd pass that along as well. Please send any necessary corrections to "tnixon@microsoft.com" or 70271,404 on CompuServe.

It's a collection, but not that kind. Going by the cover, evocative of the more lurid of the checkout-stand tabloids, one might think this is a send-up of the net. There is a lot of send-up here, but that is not all. As Prevost, himself, says in the introduction (labelled "read.me.first"), where it is impossible for a phalanx of academicians to give a fair, accurate and complete picture of the Internet, it *is* possible for a "single smartass" to offer a personal view that's nearly as enlightening, and probably a bit more fun. He has succeeded, in my view, admirably. It isn't complete. (What could be?) You won't learn a lot about the "how" of the information. The book is disorganized. (So is the net.) You may find a preponderance of items from "minor" sources (in this case, Nerdnosh, the Oracularities and White House Press conference transcripts to do with Socks), but that tends to be what you remember from net surfing, anyway. (Did you know, by the way, that the "whitehouse.gov" machine is named "socks"?) You won't learn about the shareware archives, computer or professional support resources, or the other computers to which you can connect. You *will* learn about the net community: ragged, disjointed, funny, cruel, arrogant, helpful, spiteful and sensitive. No, that description is not neat. Neither is the book. Neither is the net. Netizens will likely find fun and fond memories in these pages. Those who have not yet explored the net, and who would like a taste, should read this. If you dislike the book, you will probably dislike the net. copyright Robert M. Slade, 1995 BKINTINS.RVW 950302. Distribution permitted in TELECOM Digest and associated publications.

The easiest solution, if you don't need status lines, is: Receive 2 <-- 3 Transmit Trans 3 --> 2 Receive Gnd 5 --- 5 Gnd If you want to tie the status lines high on each end, and not use any more wires in the cable. Do the same as above and then on each end connect: DTR (term ready) 4 --> 1 Carrier detect DCD & 6 Dataset ready DSR RTS (req to snd) 7 --> 8 Clr to send CTS These connections are within the connector on BOTH ends, and do not go end-to-end. If you want to actually pass the status lines end-to-end, do the same but from one end to the other, like so: 2 <-- 3 RX TX 3 --> 2 TX RX 5 --- 5 G G 4 --> 1 & 6 DTR - DCD & DSR 1 & 6 <-- 4 DCD & DSR - DTR 7 --> 8 RTS CTS 8 <-- 7 CTR RTS This is how most commercial null modem cables are made. It takes into account all the pins except 9 which is "ring indicate" and isn't needed for this. puma@netcom.com ------------------------------ Date: Sun, 26 Mar 95 20:22 EST From: TestMark Laboratories <0006718446@mcimail.com> Subject: T1 on a PCMCIA Card?

John Combs, Project Engineer, TestMark Laboratories, testmark@mcimail.com ------------------------------ From: kevin.jessup@mail.mei.com (Kevin Jessup) Subject: The MATHLINE Project Date: Mon, 27 Mar 1995 10:32:39 GMT Organization: Marquette Electronics, Inc I just read a small, two-paragraph article on the MATHLINE Project in the March, 1995 issue of {Microwave Journal} magazine (page 47). It states that MATHLINE is an interactive telecommunications project which will be implemented with the help of the Cellular Telephone Industry Association, PBS, the nations PUBLIC schools, and other unnamed wireless organizations and providers. The article went into little detail on the "WHYS" of the MATHLINE project. The "HOWS" include laptop computers, wireless modems and satellite systems. All used to implement, and I quote, an "interactive computer-based mathematics program to improve math teaching in the nations's public schools." Fine. I'm all in favor of improving mathematics literacy (and science, and education in general). I am also aware that many (most?) public schools are not wired to the internet. I enjoy math, the internet and telecommunications both at work (I write software for medical electronic equipment) and as a hobby at home. I also have a smart and curious 5-yr-old son who can find his way around Microsoft Windows pretty well. I question, however, the costs vs benefits of the MATHLINE Program and am requesting further details on it's implementation. Will the students in the program be provided a wireless laptop, or only the instructors? Why the need for interactive access to the net? Is there some problem with current software used for mathematics instruction? How about a "simple" interactive multimedia solution based on CD-ROM and a relatively inexpensive computer? WHY the need for real-time interactive satellite access?? Will the instructor DO anything or just plug the system in and watch? How about a graphic calculator from TI or HP and an instructor who loves teaching as much as she loves math itself? Forgive my naivete, but I have never taught in the public school system. Perhaps nothing else works (still, I wonder how I learned anything ;-). Regardless of the method, is parental initiative and encouragement not the most important factor in getting a student motivated? Lacking that, can ANY program really work? I know I got political there, but it sounds like a big expense, and I feel it should be well justified. To the credit of the MATHLINE "administrators", the article DID mention that a trial run would be held this year in just 25 schools. Hopefully, these schools and the students targeted will represent an honest sample of the nation's public school system. I'm anxious to read the final report. If you have any further knowledge of the MATHLINE program, I'd appreciate your comments and/or flames.

Ivey James Lay, 29, and Frank Ronald Stanton, 22, both from the Winston-Salem, NC area were part of a ring that stole calling cards from MCI, where Lay was employed. The stolen calling cards were used to charge long-distance calls to computer bulletin board systems and computer chat lines. Mr. Lay used his position at MCI to illicitly obtain the calling card numbers which were processed in the switching equipment in the office where he worked. Approximatly 50,000 MCI calling cards were 'siphoned off' the switch over a two year period beginning in 1992 through the summer of 1994. The government successfully alleged that Lay and Stanton then supplied the calling card numbers to others in the ring. On Friday, March 24, 1995 in the federal court in Winston-Salem Mr. Lay was placed in the custody of the United States Attorney General or his authorized representative for a period of three years and two months. Mr. Stanton was placed in the custody of the United States Attorney General or his authorized representative for a period of one year. In Mr. Lay's case, because he willfully violated the trust placed in him by his employer MCI, the government successfully argued for a longer term of incarceration. The court noted Mr. Lay's willful behavior at the imposition of punishment hearing last Friday. Plans by the two hackerphreaks to appeal the court's ruling and punishment have not been announced. PAT ------------------------------ Date: Mon, 27 Mar 1995 17:27:20 -0800 From: jmadsen@qualcomm.com (James Madsen) Subject: SPIE Conference Call For PCS Papers Please note that the paper abstract deadline for PCS papers has been extended to April 14, 1995. Product-oriented papers which focus on PCS applications and uses are welcome as well. Please submit papers to SPIE as noted below. Jim Madsen Director, PCS QUALCOMM, Inc jmadsen@qualcomm.com Conference on Personal Communication Services Conference Chairs: Michael L. Gulledge, Glenayre Electronics; James Madsen, QUALCOMM, Inc. The wireless communication industry is evolving into Personal Communication Services (PCS). These services are designed to allow more efficient communications with a person instead of a location. Technologies and applications that drive these services have received much publication and attention. What will these services be? What technology will drive these services? What are the components of an intelligent network? How will the data be handled? What kind of regulations are the potential PCS companies are facing? How will the proposed technologies function together and interact with current wireless technologies? How will the service providers bill for these services, and who will generate revenues? Because 1995 is the year of the PCS auction in the US, this timely conference will address the various PCS technologies and the needs to turn a PCS license into an opportunity for achieving profitable communications services. The objective of this conference is to bring together key industry representatives, infrastructure manufacturers, PCS carriers, system designers, system network integrators, and PCS regulators and researchers who are concerned about emerging PCS applications and the next generation of PCS technologies and applications. The conference will focus on present and future wireless technologies and forces that will drive the PCS industry. Presentations will be made on PCS technologies that will be used in the narrowband and broadband PCS, and signaling techniques used in the intelligent network. What kind of air interface standards will PCS introduce? Today there are at least seven recommendations, namely, PACS, TADMA, DCT-based TDMA, composite CDMA/TDMA, DCS-based TDMA, IS-54-based TDMA, IS-95 based CDMA and wideband CDMA. Is there going to be an agreement for handling data, SS-7 networks, IS-41 interoperability, E911, and the various data base issues? What will be the difference between cellular vs. PCS vs. wireless local loop? Will voice be a commodity service, and data become the key application for PCS? How can PCS use ATM networks? Will we see fiberless video with PCS? What are the billing implications: number of subscribers vs. minutes of use? Technical papers will address such topics so that we can better prepare ourselves to undertake the major challenges in the development of the PCS technologies, data applications, regulatory standards, and economics and financing issues.

Walter MCI Business Markets 1-800-644-NEWS MCI_News_Bureau@MCI.com MCI UNVEILS internetMCI: NEW MCI-BRANDED SOFTWARE, NATIONWIDE ACCESS, CONTENT AND SHOPPING SERVICES -- marketplaceMCI opens with first "storefronts" for secure online shopping LAS VEGAS -- March 27, 1995 -- MCI today became the first company to offer consumers and businesses a full range of Internet offerings from easy-to- use software, nationwide dial-up access to the Internet, a dynamic and content- rich site on the World Wide Web (www.internetMCI.com) and with marketplaceMCI, the first brand-name secure electronic shopping area. "Twenty five years ago, MCI changed the long distance world," said Scott Ross, president of MCI Business Markets. "Today we're helping to change the Internet world. Now with internetMCI, there is a brand name online that consumers and businesses can trust for quality service and reliability." MCI today became the largest company to open a secure electronic shopping area. MCI selected 14 leading consumer and business marketing companies to open the first storefronts in the new marketplaceMCI. They are: Dun & Bradstreet Information Services, Hammacher Schlemmer & Company, OfficeMax, Intercontinental Florist, Damark International, PC Zone and Mac Zone, Reiter's Scientific & Professional Books, QUALCOMM Incorporated, Proxima, Inc., Reveal Computer Products, Covey, Doneckers, FTP Software, Inc., and National Wildlife Galleries, Inc. (Art Access). "From the day we announced marketplaceMCI, small and large businesses have been beating down our doors to open their doors on the Internet," added Ross. "These organizations are true Cyber Marketing Pioneers. They have recognized the tremendous marketing opportunities of the Internet and are taking advantage of MCI's expertise in creating a web site that will open their business to millions of potential customers worldwide." MCI said it will open the second wave of storefronts later this spring as part of its grand opening. Some of the storefronts for the grand opening include: Aetna, Amtrak, Borders Books and Music, Inc., Healthrider, Sara Lee (L'eggs and Superior Coffee), Tiger Direct, and Timberland. MCI has implemented Netscape Communications' client and browser software and Netsite servers along with FTP Software's Internet software to construct marketplaceMCI services. Through internetMCI's inclusion of industry-proven RSA Data Security's encryption technology, users can make secure online credit card shopping transactions in MCI's developing marketplace. MCI also announced today this it has begun shipping its internetMCI software, an easy-to-use Windows package for full Internet access. MCI will offer, at no additional charge, internetMCI to existing networkMCI BUSINESS owners. By offering users with a comprehensive suite of communications software, networkMCI BUSINESS provides desktop e-mail, faxing, videoconferencing, whiteboard conferencing, information retrieval and complete Internet access. In addition, internetMCI is sold separately for $39.95 (plus access charges). "MCI's goal is to make traveling the Internet easy, economical and effective," said Vinton G. Cerf, MCI senior vice president of data architecture and head of MCI's Internet initiatives. "Millions of people around the world have already taken the exciting journey on the Internet but even more are still waiting to get on board. With internetMCI, we are opening a new site on the Internet that will evolve into a major attraction for information and shopping. In short, when people think Internet, we want them to think MCI." Easy to Start and Loaded with Content In addition to internetMCI software's quick and easy installation, internetMCI provides a unique registration method that allows users to sign onto the Internet in just a few minutes. Once users have filled in their individual information and have had their credit cards verified for billing purposes, MCI's Home Page is automatically loaded where users can point and click on internetMCI's power buttons for: What's New, Directories, marketplaceMCI, Info Desk and NewsGroups. To encourage repeat visits to its Web site, MCI is frequently changing the Web site graphics. "The Internet today is similar to the early days of television where most broadcasters were merely 'putting radio' on television with little creativity and innovation," said Ross. "MCI is in a unique position because we're helping to define the medium through our marketing message." MCI's Power Buttons are tools that assist Internet users in accessing the information located in MCI's web site and other web sites as well: What's New: A variety of free information can be accessed in this section including daily-changing news stories on a variety of interesting topics (automobiles, entertainment, sports, etc.) along with weekly summaries prepared by MCI editors. Also included is a weekly-changing list of "fresh sites" on the Internet and unique-to-MCI weekly industry expert editorial columns regarding the Internet and personal computing. Directories: A wealth of free information, including national Internet directories along with Yellow and Blue Pages (government directories), can be found in this section. By simply entering in a key word, the search engines will search for items of interest to the user. marketplaceMCI: Quickloading graphics and security means that users have a new and innovative way to shop online. Users can browse various merchants for product information, graphic images and pricing. Any browser software can access MCI's Home Page at "www.internetMCI.com" However, in order to ensure secure transactions, users must have internetMCI, Netscape, or any other software that is compatible with Netscape's "Secure Socket Layer" encryption protocol. Any Internet user may download the secure browser portion of internetMCI at no charge from MCI's Home Page before making purchases in marketplaceMCI. Info Desk: This part of MCI's Home Page is designed to answer users' most frequently asked questions as well as a vehicle for MCI to provide users with an enhanced level of support. At no charge, users can download advanced software drivers for viewing images and using sound on the Internet. Newsgroups: In this section, also at no charge, users can view an alphabetical listing of Internet Newsgroups to find their favorite topics among thousands of Newsgroups. Consultancy, E-mail and Dial-up Access MCI also announced today that it is providing assistance to organizations who wish to have a presence within marketplaceMCI. This MCI consultancy service helps organizations set up their own storefronts in marketplaceMCI in order to market their goods and services to Internet users. For sending and receiving e-mail on the Internet, internetMCI customers can purchase e-mailMCI separately for $24.95 through MCI. Based on E-mail Connection, this e-mailMCI multiprotocol component allows users to create their Internet POP3 and MCI Mail messages off-line along with managing those messages through folders, key word searches and both "easy" and "power" user modes. Also, e-mailMCI users can exchange messages with any e-mail system attached to the Internet, including CompuServe, Prodigy and America Online. By automatically dialing into the Internet, e-mailMCI quickly downloads and uploads messages. Along with internetMCI software, MCI is providing a full range of Internet dial-up access services at speeds up to 28.8 Kbps. Nationwide 800 dial-up service is immediately available, and local dial-up service will be available in 64 US cities by late April. For business users, MCI already offers an extensive range of dedicated access options from 56 Kbps to 45 Mbs that connects directly into MCI's national Internet Protocol (IP) network. As a promotion, between now and June 30, 1995, internetMCI customers can have unlimited dial-up (local or 800) access to the Internet for only $19.95 per month. After June 30, users will pay $9.95 per month for the first five hours of local access and $2.50 for each additional hour. Users who wish to dial in via MCI's 800 service will pay $6.50 for each hour of access. As with all MCI Business Markets products, MCI's "24 by 7" customer service is available. Customers who would like more information on internetMCI should contact MCI at 1-800-955-5210. MCI, headquartered in Washington, D.C., has expanded from its core long distance business to become the world's third largest carrier of international calling and a premier provider of data communications over the vast Internet computer network. With annual revenue of more than $13.3 billion, the company today provides a wide array of consumer and business long distance and local services, data and video communications, online information, electronic mail, network management services and communications software. # # # ------------------------------ From: telecom@eecs.nwu.edu (TELECOM Digest Editor) Subject: MCI's New Thing Date: Mon, 27 Mar 1995 22:10:00 CST So, from reading the press release issued today by MCI we see that MCI plans to hand out the Usenet newsgroups to their customers at the aforementioned prices.

(My first major article on an Internet list was an analysis of the fact that messaging systems seem almost predisposed to generate misunderstandings.) So, I am very pleased to see a study of romance online. I am not quite as pleased with the almost total preoccupation with "cybersex". I agree that an insistence on purely platonic relationships in the digital medium is both silly and futile. Nor do I dispute the assertion that "typing dirty" to someone else can be stimulating. (At the same time, I am reminded of Bill Cosby's comment on erotica, that, if you are hungry, you don't go and watch your neighbour eat a steak.) Primarily, however, I think it belies the subtitle to the book, "A Practical Guide to Digital Dating". Some of material is quite practical. Chapters four to six provide a reasonable, if very basic, guide to bulletin board systems (BBSes), commercial online services, and the Internet. Chapter two also provides some helpful tips for the online novice. Lurk before you leap. Make friends, first, in the topical areas: the "Hot Tub" chat area devotees are not great conversationalists. Be honest, but careful, and don't believe everything you read. However, with "computer sex" popping up repeatedly, it's easy to see that this work started life as a series of magazine articles. Dating gets fairly short shrift here, although the material is nowhere prurient. You can develop friendships, and even romance, online.

PAT] I have no idea what scheme is being used now, but some of the history of expanding the NANP numbering space is covered in an old Bell System publication _Notes on Distance Dialing_. (I believe NODD has been reincarnated as Notes on the Network.) I'd love to quote a lot of this; it's fascinating stuff, but doubtless someone still holds copyright, so I will review a few fragments. This is from the 1974 edition: "It has been apparent for many years that additional code relief [beyond moving from 2-letters+5-digits to 7-digits] would be required to extend the life of the [NANP] to the end of the twentieth century. The relief plan adopted requires that codes previously reserved for only NPA code assignment be used as CO codes also, and vice versa. This arrangement, called "Interchangeable codes" necessitates certain special equipment arrangements and dialing procedures that are discussed in this section." [discussion of the NANP, NPAs, SACs, WATS, and TWX(!)] "Some time after 1995, it is estimated that the 21 NPA codes still unassigned (end of 1974) will have been used and that it will be necessary to start using NNX type codes as NPA codes. In the interest of minimizing ambiguity, it is planned to assign the NN0 codes first in accordance with the sequence shown in Chart 5. ..." "Chart 5" lists the 63 available NN0 codes (with a footnote to the effect that code 950 is reserved for a future network-wide service :-) ) and says that they should be assigned as CO codes starting at number 1, and as NPAs starting at number 63 and working backward. The beginning and end of the chart are: 1 530 55 660 2 420 56 490 3 870 57 250 4 780 58 220 5 440 59 650 6 360 60 590 7 920 61 520 8 830 62 480 9 620 63 260 So the first non-NYX NPAs should have been 260, 480, etc. Why they didn't stick to this very sensible sounding plan I have no idea. This also shows that the claims of outrage by PBX makers and administrators that they had no idea this change was coming are nonsense. AT&T knew it was coming twenty years ago, and predicted the date correctly to within a year. (Actual growth was somewhat faster than they expected, but they didn't plan on using the N10 codes as NPAs in the 1974 document, which is what saved everyone's bacon.) This book was no great secret; I was able to get it on interlibrary loan from the Bell Canada library in Toronto to my local public library in 1975.

Through resellers expect to pay a flat rate per minute for 800. The range to expect would be .139 - .165. There two types of calls over ISDN. Switched and Packet. This is determined on how your ISDN is configured. Switched calls are your toll rate X 2.

The "solution" is to "tune" KERMIT, after getting an up-to-date version of the software, via anonymous-FTP to 'KERMIT.COLUMBIA.EDU'. Kermit promotional material follows: We (Kermit developers) don't mind responding to queries about new stuff, items that aren't clear from the documentation, etc, but yes, people who use Kermit software a lot are heartily encouraged to purchase the documentation because: 1. It's not that expensive. 2. It will answer most of your questions -- we put a lot of work into it -- hundreds of examples, step-by-step instructions, illustrations, tables, appendices, tutorials, glossaries, a comprehensive index. 3. It relieves the load on the network. 4. It frees up time of Kermit developers and tech support people to do more development and tech support. 5. Most important of all, income from the sales of Kermit manuals is the primary source of income that funds the Kermit effort.

(1-800-827-6364) Reply-To: herraghtyj@aol.com (HerraghtyJ) If the calls are outbound from your private phone system to the local dial tone provider, you can probably busy out the line in system software or by throwing a dipswitch somewhere. This will take the line out of the hunt group. If it is a matter of the calls coming in to you and they are analog trunks, first, disconnect them from the phone system. If the inbound trunk is a DID trunk, this will kill it immediately. If not, place a phone on it, leave it off hook, then call your local provider for service. Sometimes you can get the phone number of trouble desk in the Central office and they might busy the phone line out for you. Good luck. ------------------------------ Date: Mon, 27 Mar 1995 13:03:02 -0500 From: allbery Subject: Re: Microsoft Techs and Phone Calls Reply-To: allbery@junior.org (allbery) Organization: Akademia Pana Kleksa, Public Access Uni* Site In article TELECOM Digest Editor said: > She said a relatively small handful -- one hundred perhaps, or maybe two > hundred -- of customers always called them repeatedly, over and over.

I could have told you that; I work with such people. So does my mother. (Worse yet, the one my mother works with is in charge of Information Services for her company ...) Hard as it is for me to feel sorry for Microsoft, in this case I do. Brandon [TELECOM Digest Editor's Note: I guess the reason they went to paid customer support (that is, a small amount of free support upon purchase of the software then the customer is required to pay for additional support) was because -- as this lady explained to me -- a couple products of Microsoft in the last few years caused the company to take such a bad hit on customer support -- that is, it was so extremely expensive -- that the profit on those two products was virtually nil. When I talked to her she mentioned the hundreds of phone people all of whom spend seven hours per day just with customer support. I asked her, since payroll is about 80 percent of the expense in any company, if that many people were doing that one limited task for all that time each day, where, exactly was the profit for the company? Her answer: well ... there wasn't any on product 'x' and product 'y' ... yeah, a little, but not at all what was commeasurate with the development and marketing expenses. Where the majority of customers did in fact read the documentation, figure it out and manage nicely, maybe making one or two calls lasting a few minutes each and that was it, there were those relatively few -- a couple hundred or so -- that just pesterd the techs to death day after day, hour after hour. They never read documentation, were unable to (or refused to) follow simple instructions, and (as the woman said to me) some would tell lies to the techs. I asked her why would the customers lie? She said, "because they did not know what to do and they were embarassed to admit it and they would 'make up stories' about messages on their screen or the way the display on the screen looked; things we knew they could not *possibly* be getting as results. We'd tell them to do one thing, they would argue about it, refuse to do it and then lie and say they did do it." Some were angry they could not call in on an 800 number and sit in the queue for 45 minutes on Microsoft's nickle instead of their own. She noted that paid customer support is not intended to be a profit center for the company but merely to take some of the burden away. The initial free support is geared for the 'average' customer; enough free time is allotted that the 'average' customer still essentially gets totally free support.

The problem is that the signal being emitted by a receiver is on a different frequency -- and what frequency that is is determined by (1) its IF frequency, (2) the tuned frequency in question and (3) whether the local oscillator is on the high or low side of the tuned frequency. If you knew that your target was using Brand X, Model Y -- as British intelligence officers knew when they used that trick against Nazi spies, having found out what makes and models of gear were in use inside the German embassy before the war -- you could monitor a specific frequency to find that local oscillator.

When these patterns change suddenly and the volume of calls increases heavily, these high fraud certainty calls are redirectd to an operator. In fact we have developed such a system for SS7 network. This system is virtually invisible to the network as it induces less than a milli second delay. This system will redirect the fraud calls to an operator. We have succesfully tested this device in some SS7 networks and found it to be effective. I am sure this type of system could be used for preventing cellular fraud too. ------------------------------ From: d92-sam@black29.nada.kth.se (Sam Spens Clason) Subject: Re: X.25/ISDN Prices; Global Information Wanted Date: 27 Mar 1995 10:29:18 GMT In smckinty@sunicnc.France.Sun.COM (Steve McKinty - SunSoft ICNC Grenoble) writes: > In article , cogorno@netcom.com (Steve > Cogorno) writes: >> Rishab Aiyer Ghosh said: >> 1 MB = 1024K = 1048576 Bytes=8388608 bits=65536 octets (1 octet=128 bits) > Nope.

PAT] ------------------------ I'm sorry but I am in the midst of a deadline crunch at ForbesASAP, explaining why computer technology will enhance all our lives, why its manifest destiny to usurp the telephone industry will lead to an efflorescence of global mobile communications, why the learning curve for mobile telephony will be at least ten times faster than the curve for wired telephones and why the assertion by a development VP at BellSouth that the price elasticity of telephony is negative -- the lower the price the less the revenue -- is preposterous. Thus I am too busy contributing to the information glut to explain to Neil Postman that the computer is the epitome of current technology, that made in the image of our Creator, to create, human beings can no more forgo new technology than they can relinquish food and drink. Academics take wealth and comfort for granted and imagine that the world would be better if all of us wrote philosophy or pursued contemporary art. But contemporary philosophy is mostly barren because it is divorced from the process by which humans create wealth and thus perpetuate life and extend it to areas of the world where the average lifespan is about 28. I do not think that life is ever easy. I think the effort to master the human predicament entails constant work and struggle. The heart of this work and struggle is the creation of new technology, new machines, which allow people like Neil Postman to worry about absurd non-problems like the information glut, to which the computer is a solution more than a cause, and to imagine that technology is unnecessary to relieve the distresses he discusses, such as famine, plague, joblessness, and war. We give it up and we will be ruled by monsters like Saddam, who Postman imagined in 1990 posed a huge threat of an extended war. Thank you for sending me that eloquent though misguided paper. Best, gg [TELECOM Digest Editor's Note: And *thank you* for your eloquent response.

And a final comment for GG: should you decide to add still a bit more to your book, an excellent choice of subjects might be, 'what do you do about the Postman people?', i.e. getting over that hump; working around the all too common assumption by people who think that *you think* that the computer is going to solve all the world's problems and then proceed to answer the statements they arbitrarily put in your mouth with answers of their own. Yes indeed, I'd certainly be interested in seeing a much more detailed treatment given by yourself to the questions Postman raised.

Many coin phones have been converted back to rotary dialing for this reason, and the drug dealers have not been reported to be carrying DTMF pads. If there's money in the location, the phone will start working correctly. And if there's no money in the location, no one is using it, and there's no loss. After all, coin telephones remain in the busy locations where they are best known as "junkies' piggy banks." > public who has never heard of voicemail, and the ninety-five percent or so > who don't have it or need to retrieve anything from it get punished as > well by having the one payphone in their neighborhood which formerly had > been operated by Bell replaced by a COCOT.

PAT] Actually, most problems of this nature occur with COCOTs, which refuse to allow you to access preferred interexchange carriers (regulations be damned). The typical COCOT provider will be much more sensitive than the LEC to customers' needs to use the DTMF pad when it is brought to his attention -- especially when the alternative involves attempted repairs with epoxy. The LEC will weigh the political pressure to disable the DTMF more heavily than will a private owner, who is more concerned with the revenues he loses by frustrating people who need the DTMF pad. (For the LEC, it all gets added to the revenue requirement, and recovered from the residual customer.) ------------------------------ From: oppedahl@patents.com (Carl Oppedahl) Subject: Re: March 1995 NYNEX Bill Insert - PulseNet Service Date: Tue, 28 Mar 1995 03:58:16 GMT Organization: Oppedahl & Larson In article Jonathan_Welch writes: > This was on the last page of my bill insert this month: > Your Alarm System Protects Your Home and NYNEX PulseNet Service Helps > Protect Your Alarm System > You rely on your alarm system to protect your family and your home. > But to do its job, the system must remain connected to your alarm > company through the phone line.

What I find annoying about the insert is: It does nothing to tell you whether the service is new or not. As far as I can tell, the service has been around for at least ten years. It is an insert that exploits the monopoly position of the local telco, forcing you to read their ads and drawing on their mailing list, which is a customer list, that was developed at ratepayers' expense. Essentially, all the poor old grandmothers who have phone service are subsidizing this mailing, and the profits from the mailing probably mostly get routed to dividends, not used to reduce cost of local phone service. ------------------------------ From: Steve Elias Subject: Re: Routing Inbound FAX Using DID Date: Mon, 27 Mar 95 22:55:04 PST > I`m curious about LAN FAX servers that route inbound FAX messages to > e-mail addresses using Direct Inward Dialing (DID) lines.

Ten lines or ten thousand lines, no matter. I am considering starting a BBS, and installing a dozen lines (maybe two). I would like to learn about good wiring practices -- I know what a 66-block is and I know how to punch down wires. However, I am just a ham / electronics hobbyist, not an ex-phone company wiring whiz. I don't know the difference between "good" and "bad" practices, really, beyond common sense, and have _no_ idea on where to get information on color codes, etc (How does one wire a 25-pair cable to a 66-block?

There is no need to trademark this number, just as there is no need to trademark a memorable numerical number such as 800-222-2222, or a mailing address such as 123 CocaCola Road, Atlanta, GA. That is what I mean when I say a trademark is unnecessary. No, it's not a legal opinion. It's a fact: trademarking 800-FLOWERS buys you absolutely no protection. So the only thing you can be hoping for is protection of a U.S. trademark outside the U.S., something no U.S.-registered trademark -- telephone number or not -- enjoys today. Trademarks must be individually registered in the countries where one does business, and priority is applied on a country-by-country basis. If I trademark "OppieCom" in the U.S., and later discover that a German company exists with the same name, I'm not going to be allowed to do business in Germany as OppieCom. That the U.S. has more 800 numbers than the rest of the world means not a whit to the rest of the world. Quantity is not priority. If you're proposing that the U.S. strong-arm others into submission by refusing to route international 800 calls that collide with U.S. numbers, then I'm certain the world will be happy to live with that situation. It's no skin off their nose. The losers will be U.S. callers, not overseas companies. On another note, do you also contend that the owner of 1-800-356-9377 (FLOWERS) owns the phone number 356-9377 in every other area code? If a local flower shop in Ventura, CA wants to advertise their *805*-356-9377 number as "Just dial FLOWERS", are you saying they would infringe on 800-FLOWERS? I think you have a logical conundrum here. If you say "yes, they're infringing", then you have to contend with giving every alphabetic 800 number priority over local numbers. This hardly seems fair to the 50-year-old mom-and-pop flower shop, and flies in the face of existing trademark law. On the other hand, if you say "no, they're not infringing", then you must explain why these numbers don't infringe but international numbers do.

It certainly is AT&T employees over 300,000 people (I think that's just in New Jersey, but it may be the national number). How can you expect all 300,000 of them to know about a new service. They do have a daily bulletin to all employees that is sent out electronicly, but not everyone reads it. As a side note: I've seen a lot of AT&T employees putting their personal 500 number on the title slide when they make presentations inside and outside of the company. I think this is a good trend.

(1-800-827-6364) Reply-To: herraghtyj@aol.com (HerraghtyJ) Interesting problem. The first precedent to establish is that the phone company is engineering the circuits all the way to your Mitel Location. That must be true for your trunks as well as OPX's. Also, please ensure that your OPX's are terminating onto OPX Ckt cards at the PBX. It is otherwise very easy for all concerned to test all circuits only to the established POP which could easily be a mile away from your Mitel. There is much precedent already existing to have the phone company Engineer the circuits over somebody elses copper cable plant. If Telc or University has a problem with that, ask them what they would do if you ordered your trunking in on a T1. The Local provider would have to provide the smart jack within a hundred or so feet of your Mitel. Or, if you ordered a leased data line from off campus, that too would have to be engineered all the way to its final destination, and not just to the University POP. There are multiple instances of Universities 'giving' copper to local Telco's to service to end user's whose business happens to be on the campus. For instance, students Union with McDonalds, Arbys, etc. Or, do you have an ATM/Money Machine on campus, how does that data line get there. You can bet your last buck that it doesn't get repeated through the campus phone system. It is very carefully engineered from the banks computers to the final destination ATM. It is always a great temptation for a tech head to apply bandaids with repeaters, amplifiers, boosters, line conditioners, gain circuitry etc. However, in this instance, a Fed with a good head for sorting out silly administrative shirkers might just win the battle by making parties live up to their responsibilities and provide some good service.

As the original poster of this thread, I believe it is time to clear up the us use of the word "tax" and provide an update to the group from what I've heard (not confirmed). First, I apologize for the dramatics by using the word tax in this thread. It was intended to draw the attention of readers that do not spend their days reading tariffs or understanding the nuances in telephony terminology. From that standpoint, and in my own behalf, I believe it served its purpose. It is my understanding that, indeed, the original proposal by the FCC was to increase the line fees associated with ISDN through a tariff. It has been brought to my attention that -- possibly due to a combination of both RBOC and end-user attention to this issue -- the FCC is now opting for presenting a ruling on this matter. This opens the issue up to greater public comment. In discussion with "someone in the know" at one of the RBOC's recently, it was related to me that the CALC is viewed as a franchise fee that the FCC imposes on the telco's. We further discussed the impact of the FCC ruling on the cost of an RBOC to institute the fee accounting and how that can affect user pricing. There are still many unresolved concerns about the entire FCC proposal for increased fees. The most predominant are: -- With the EPA placing such an emphasis on reducing pollution by requiring work-at-home policies on employers in "hot spots" in the country, the FCC proposal is only going to increase the cost of implementing those plans because ISDN is a critical component in most work-at-home applications. The leaves the basic question of "Where is the continuity from the government on this issue?" -- With the advent of Multi-Rate ISDN (Single Call - Nx64 channels from the telco switch provided to the subscriber) right around the corner, it is obvious to some of us that the CALC method is outdated for the technology and is being forced to fit where it does not belong. -- In nearly every existing state tariff, residential service is provided only on a 2B+D basis thereby requiring residential subscribers to pay a CALC regardless of their willingness to get both B channels. (I'd say every state where a residential tariff exists, but I've not done the necessary homework to make that definitive a statement). -- With all the discussion of deregulation, video dial-tone, etc, it is logical to conclude that the CALC itself might disappear or be completely revamped to accomodate the growth of the telecommunications industry soon after the proposed increase is put into effect (BTW, soon in the telecommunications industry is defined in years). It seems illogical to impose this structure with the left hand while the right hand is potentially doing something entirely different. I have not been made aware of when the FCC hearings are to be held on this issue. Anyone that has that information, please post or e-mail me with that information. On a positive note, it does appear that we, the average citizens, have already had some impact on what the FCC is intending to do. It is important that we continue down that path.

Telecom "Reform" Now Under Way Reply-To: monty@roscom.COM Forewarded to the Digest, FYI: Date: Sat, 25 Mar 1995 20:11:17 -0800 From: Jim Warren Subject: GovAccess.113: BEWARE! Telecom "Reform" now under way WATCH OUT! Our online future can be turned into a digital wasteland as bad as the TV wasteland that followed that technology's great hope of the '50s. This GovAccess concerns only one issue -- the "Telecommunications 'Reform' Act of 1995." It has already cleared its first Senate committee hearing. As a comparably trivial gargoyle, it already includes Sen. Exon's "Communications Decency Act of 1995," amended into the bill in that hearing. No one knows how this "reform" legislation will finally turn out -- especially not when it eventually comes out of a House-Senate conference committee that will coyly meet behind closed doors, probably to be steam-rollered through a fast-track enactment by Congress. As an example of the dangers, here are "reliable rumors" that one of the nation's leading network experts chose to report in mid-January. Farber does not thus place his reputation on the line lightly. --jim &&&&&&&&&&&&&&&&&&&& "Reforming" Government-Granted Multi-Decade Monopolies (uh huh!) Date: Mon, 16 Jan 1995 06:44:54 -0500 From: farber@central.cis.upenn.edu (David Farber) Subject: The planned Communications Act Re-write of the New(t) Congress I have paraphrased a message from a source who claims that this has been substantiated by at least two other sources. PLEASE note that I can neither personally confirm or deny this information at this time, so ... [just like most important political information --jim] Some may call this another of the "hysterical ravings" heard out of DC. Who knows but there have been such in the past that came true. I suggest watching events and see if you see any sign of this happening. If you do, come back and carefully re-read this message. Dave I paraphase: For what it's worth, my impeccable source in DC just called to tell me how the Communications Act Re-write will appear when a carefully orchestrated scenario runs its course. ... All the deals have all been made over the holidays with the critical opposition that stopped last year's bill: the IXCs [long-distance carriers], cable, etc. It will be a very complex bill, packaged with the right deregulation words (get the government off our backs), universal service, and futuristic "3d Wave" stuff from Toffler and Gilder. The media blitz is being planned for maximum effect. Clinton won't oppose it because if he does it will appear that he is reneging on Information Highway promises. There is no stopping the steamroller now, and there won't be any time for major forces (other potential players in the NII -- the Microsofts, Hughes, etc. -- to do a decent analysis without looking like they are naysayers). The details -- as usual -- are what counts. The bill will turn residential, small town, suburban, and rural _local access_ into a permanent natural monopoly with a single gateway for services TO the home. The BOCs don't think there are any services FROM the home business worth considering, other than voice and low-speed return data for games. The RBOCs, have given up on medium to large customers. They realize that they already lost that market to AT&T and the niche players, MCI & Sprint. But by controlling access to the home, they figure they can control everything else, and have a chance at getting a few large users by packaging the residences for them. This way they might actually gain market share in the IXC business. AT&T knows they can't fight this Congress without looking like the spoiler, so they will take their chances on radio access, manufacturing, and the more lucrative businesses. It looks like the RBOCs will pull this off, because the separate interests are now stronger than the mutual conflicts among the biggest boys in town. Cable knows they are finished if they have to compete with the LEC's cash flow and new, and better, coax networks are constructed; so they might as well settle for what they can get now. The bill will have the right incentives for the major MSOs to lease-back their coax for the LECs to run. Malone already said so. One "Uniwire" into the home discourages future competition, especially with complicated lease-back arrangements. Any competitor will think twice about trying to breach that monopoly. They are simply following the successful strategy that AT&T used to play W.U. off of 3d parties, like RCA, for decades; W.U. used to get sweetheart deals for circuits with the FCC blessing. No one else even bothered to think about competing until MCI discovered microwaves. These lease-back arrangements will look clean to the uninitiated. Uniwire will be reinforced by control of the settop box interfaces. A barrage of economists will be engaged to argue that natural monopoly, under some new name, is best for everyone because it broadens opportunity. If you think crystals are screwy, wait till you hear the new mantras. The BOCs don't know what to do about radio, but don't believe the technology for broadband radio is here anyway, and have come up with a legalistic strategy that empowers the FCC to slow down any competitive forces using alternative carriage. This will take three steps: 1) Federal pre-emption of States' rights in ALL communications fields -- wire, radio, switching, rates, whatever. But State's rights are a Republica mantra. To prevent this looking like more centralized government (which it is): 2) An "ombuds panel" will be set up under the FCC, but with extraordinary powers to bypass the Administrative Procedures Act and expedite the CFRs without 11 months of notice, etc., to settle all disputes between the States and the Federal government on communications matters. This will be presented as State oversight to protect universal, vaguely defined, services and the like. Everyone who thinks they matter are hustling to get on this panel, for then they will be more powerful than the Commissioners themselves. It will look balanced, with even one FCC Commissioner or two on two panel, somebody representing consumers, labor, etc., but since the GOP expects to win the next Presidential election, within 2-3 years it will be totally stacked. Of course, if the Democrats should ever win anything again, and the BOCs get into financial trouble, which is very likely given that the residential business has always been a dog, all the mechanisms for nationalisation of local carriage will be in place. So why should a good Democrat oppose this? Power swings back and forth in Washington. And to make sure none of this unravels too early: 3) the Justice Dept. will be cut out of all antitrust matters related to communications. All this will be called cutting down centralized government!! The message is that too much money has been spend on this deal for anyone to back out now. What can kill it is the State pre-emption clause. The Governors of the five, so-called "seed" states in telecom (FL, NY, CA, IL and CO) are going to want something big in return for blessing pre-emption. They are in terrible financial shape. So expect weird pork barrel monies flowing for totally unrelated things: releasing FEMA funds for disaster relief in Florida, California, and who knows what else. This is a very large country with a very large economy -- it is easier to move money around than the average citizen thinks. A small portion of a large number is still a large number. So much for capping Federal spending. The other wild card is the broadcasters, who last year stuck in a provision to use the so-called HDTV UHF channels for anything but. However, the networks would love to drop foreign ownership provisions and they might relent on data over former video channels -- which they really don't understand anyway -- for a chance to make better deals with foreign entities. The Republicans are counting on cable & telcos to behave themselves and not raise rates until after the next Presidential election. There is nothing to stop the steamroller now but if they can't get the bill signed into law by Feb 15th, the deals are all off, I am told. end of paraphase &&&&&&&&&&&&&&&&&&&& Three Key Telecomm "Reform" Questions (Among Many) 1. Would the communications giants that zealously seek to become information/content and value-added services providers assure a level playing field and full and equal access to small entrepreneurs seeking to provide innovative services at lowest cost - if they are not forced to do so by the same statute that will force them to provide such a level playing field and equal access to each other? 2. Will we have "universal access" or only "universal service"? Universal *service* will guarantee only that we can be obedient couch potatoes, emitting digital cash to consume whatever trivia the giant corporations deign to dribble out to us. Universal *access* will assure information and service providers competitive access to the wired and wireless communications channels that have been government-granted corporate monopolies for so many decades. Adequately-structured universal *access* could allow *real* competition with the giants, competing with - and often beating - them in providing maximum innovation at minimum cost to the user. And I don't mean some idiotic delusion of competition - like the arrogant fantesy that mandating two cellular-phone providers in a given market provides adequate "competition." Universal *access* can allow all of us to become information and service entrepreneurs - even from "the privacy of our own homes." However, functional channel monopolies will kill that dream. 3. Where the hell are the newspaper publishers? Why aren't they screaming bloody murder? Don't they realize that they can become minor throw-aways within a decade or two, if they are shut out of competitive access to these communications channels by the giants that own the channels? --jim &&&&&&&&&&&&&&&&&&&& "Behind all the hype shaping the electronic highway are corporate interests.

Does digital encryption significantly reduce the threat of cellular fraud such as cloning? What about other types of cellular fraud? Do any of the encryption-capable digital cellular phones indicate to you whether encryption is enabled for a particular call? I understand some of them will tell you when they're operating in digital mode, but that's not the same thing. I also have a few questions about digital cellular in general: 1) Do people on this forum believe digital cellular will eventually replace analog cellular? How soon? 2) Currently, analog cellular phones are often available free with one year service contracts, but digital cellular phones are expensive. Do people on this forum believe that digital cellular phones will eventually be available near free once the digital conversion is much further along? It appears that digital cellular is being pushed by service providers because they can squeeze three times the number of calls on the same bandwidth and charge only 10%-20% less.

I want to start planning and implementing better WAN connectivity than what I have currently -- FedExing tapes, sporadic ISDN and/or costly dialup UUCP and SLIP/PPP. Of course, with such ventures, the issues involved are telco-oriented as much as anything. Given: A few-hundred-person company homed in the U.S. with an inhouse TCP/IP network and little else, data-network-wise. Given: A couple of small offices -- 20-30 people -- in various parts of western Europe, with a couple more on the way. Given: We're not afraid to spend a little money, just not a fortune. These offices DO make money, after all. :) I want to establish a dedicated 56k+ circuit between these offices and my U.S. office. I don't care about latency too badly (though shipping tapes back and forth is a little too high in the latency department for my tastes :) ). Most of the circuit would be used to move data, but ideally, I'd like to be able to establish a voice channel riding along the data channel if possible, so I could cut down on LD charges between offices. Ideally, I'd like a single network pipe to somewhere as opposed to a solution which requires me to build a whole lot of infrastructure every time I add an office. At this point, I'm in the preliminary planning stages, but it seems like satellite connectivity would be my best bet. However, I'm sure I don't know all the connectivity options that might be available, and I'd be very interested in how people are doing this sort of thing. I come more from the LAN management side than the telco side of life, so please be gentle with me if I'm asking something outrageously stupid. Michael J.

Due to my role as liaison between our local PBS station here in Cleveland (WVIZ), and my company's charitable contributions team, I have some exposure to the MATHLINE project. I'm trying to get someone more closely associated with the program to respond here too. WVIZ was one of the first stations to try MATHLINE and my company donated a little seed money last year. We also persuaded one of our partner schools to enroll a math teacher in the program; he reports he is quite satisfied with MATHLINE. > The article went into little detail on the "WHYS" of the MATHLINE > project. My understanding of the program is that it provides math teacher training, using satellite instruction to a number of remote sites. Teachers receive lesson plan guidelines, videotape teaching episodes, and computer bulletin board numbers/passwords they can use to pose questions directly to the MATHLINE instruction team. Teachers can receive assistance in understanding how to apply the video tapes, example exercises, or teaching methods. > Will the students in the program be provided a wireless laptop, or > only the instructors? This is the first I'd heard about wireless laptops. This year the only requirement was a computer and modem that could access a local MATHLINE access number. > Why the need for interactive access to the net? Primarly to access samples, optional portions of the exercises, and to have application questions and teaching questions answered. I don't think students have this access (at least they aren't supposed to), only the teachers. > WHY the need for real-time interactive satellite access?? Satellite access is used during presentation of the course materials to the math instructors. I don't think it is used at any other times. > Will the instructor DO anything or just plug the system in and watch? The instructor will facilitate the videos, and break away from them frequently. There are many places during the tapes where the procedure is to stop the tape and do things with the class. The lesson guidelines provided also include sample exercises in addition to what is on the tape. > Forgive my naivete, but I have never taught in the public school > system. Perhaps nothing else works. I can't speak to this point other than to say that your five-year old who is tooling around in Windows now will probably expect a multi-media presentation to keep him interested. Interestingly (to me, anyway), one of the largest expenses for our local implementation of Mathline is "teacher release," i.e., paying for substitute teachers to permit the math teacher to attend these sessions. Many local schools no longer include personnel development in their budget, I guess. Or at least they can't afford to do it during the school year. So the program pays for the substitute while the teacher is being trained. Another note: MATHLINE is designed such that the teacher who participates in the satellite sessions becomes the local trainer for other teachers in her or his own school (or whatever consortia she/he is affiliated with). Thus, we are hoping for a good fan-out effect of the materials, which can be re-used by multiple classes, etc. One of the tenets of our company's charitable funding is to maximize the impact of our contributions; this program appeared to meet our criteria. We will be re-evaluating its success this year to determine whether we will continue funding.

Do you have any idea wether this feature works even with a Motorola 7200 GSM phone? I tried shortening pin 2/3 with a small piece of aluminium paper but nothing seems to have happened after that when I switched on the phone again. Is this because there probably is no local mode on GSM phones, as all the information is stored in the SIM module? Thanks for any idea, Jurgen [TELECOM Digest Editor's Note: I really don't know the answer. I know what you did (assuming pins 2/3 are ground and the pin to be sent to ground) works with lots of other Motorola cell phones. The other thing you *must* be careful of with this experiment is keeping that connector (aluminim foil, or a tiny little bare wire or whatever) *away from where it does not belong*. Get it in the wrong place accidentally (or it slips and falls in the wrong place in the process of reinserting the battery) and you might just short out the battery or worse yet damage the phone. Be very careful working in such a small space if your fingers are not very nimble. Does anyone have some schematics for Jurgen's phone they can share?

"(g) Any customer affected by a boundary realignment should not be affected by any subsequent realignment for at least 10 years." This statement is still in Bellcore's "BOC Notes on the LEC Networks - 1990" (SR-TSV-002275) In all fairness, with that statement in mind, I'm not sure how they could have handled the 312 split several years ago other than creating a new NPA for cellular/pager numbers in addition to 708.

I've been watching the discussion of what we call 'reliable disconnect' around here with a good bit of dismay. You should be aware, that despite the discussion that's been going on here, in most cases you won't get a reliable disconnect signal when the other end hangs up. Most home answering machines will decide that the far end has hung up after a period of silence. I've been burned by this one when I took some "think time" and had the answering machine hang up on me. If you want to know whether your device is really detecting disconnect, I suggest you do an experiment where you call it, chat it up a bit, then go silent. Ground start trunks definitely do provide signalling on disconnect; some loop start trunks may, but don't bet on it. As I was typing this, I tried an experiment with my home answering machine. It hung up on me after about 15 seconds of silence (Yes, I'm sure; I have ground start trunks with reliable disconnect here at the office).

This is how they do it: The people they are after are the people who clone telephones and sell "phone calls" to people on the street. These phone calls are usually to other countries. For $5 or so buy a 20 min phone conversation that would normally cost much more. This is real popular in the city in poor areas that a lot of immigrants live in. The criminals provide the locals with an affordable way to call "home". This is big business in cities like New York. They catch these guys with spectrum analizers. An unmarked police car drives through an area where the phone brokers are known to operate and when they see a spike in the 825-840Mhz range coming from a van parked on the side of the road with tinted glass, they say "a-hah!". An undercover cop then buys a phone call from the van in question, then arrests are made. This is how most of the cell phone cloners get caught. ------------------------------ From: d92-sam@black29.nada.kth.se (Sam Spens Clason) Subject: Re: CDPD vs Ckt Cell Data UPDATE Date: 28 Mar 1995 10:37:46 GMT In mcardle@paccm.pitt.edu (Terrence McArdle) writes: > In article <95.03.21.221ghet@eecs.nwu.edu>, aircom1@aol.com (AIRCOM1) > wrote: >> A bit is a single 1 or 0, and a baud is the "raw" number of bits that can >> be sent per second.

Yes, I've heard of it. I was familiar with it long before I wrote my earlier comment. But the two are not equivalent. The person I was responding to (Carter) had proposed that the number of anyone deemed "obnoxious" by the complaining party should be revealed on request, without regard to the caller's privacy. Call Trace, as Page admits, does nothing of the sort. With Call Trace, telco reveals the number only to the "proper authorities," the exact definition of which which seems to vary from region to region. The typical price, in the range of $1 to $1.50, is charged for each "successful trace," regardless of whether those authorities actually take any remedial action based on the information supplied. I question whether telco really loses money on this service. If so, the question is, relative to what? Considering that they do not now charge for (nor widely publicize) the services of the Annoyance Call Bureau, the $1-and-change revenue from each Call Trace would seem to be pure gravy. Far from viewing this as a "positive development," I would also question the implications and precedents set by providing this service for a price, however nominal. Suppose you or I were in possession of information relating to the commission of a crime. (Harassing phone calls are usually only a misdemeanor, but threatening ones can be a felony.) What would our neighbors think of us if we refused to provide that information to the authorities unless we had received a price for revealing it? We might refuse to cooperate, on some principle or another (unless subpoenaed). Or we might agree to cooperate and provide the information freely. But to make our cooperation conditional on the payment of some sort of blood-money would be, in my view, unseemly at best -- and more so when you consider that in this case we're billing the victim. Finally I question how effective the service actually is. Sources have reported that the police in these parts (suburban New Jersey portion of the New York metropolitan area) routinely ignore transmittals of Call-Trace information until several reports, in some cases up to ten, have been received. GaryN gnovosielski@mcimail.com [TELECOM Digest Editor's Note: Like yourself, I have always questioned why telco charges for traces handled via *57 when the older, and still functioning Annoyance Call Bureau at telco does the same thing for free. My feeling is they *have* to do it free on demand if you know enough to demand it. Legally, you have the right to peaceful and uninteruppted use of the phone. Telco has a legal obligation to provide that to you. To the best of my knowledge however, Ameritech -- our local company here -- does not charge for *57 either.

The actual cost of ISDN in many, or most, areas of the United States is high enough to discourage the sort of mass deployment that it needs to be viewed as truly successful. In the past month, a lot of attention has been paid to an FCC proposed rules clarification that would have raised the price of some ISDN lines by as much as $6 per month. From the hue and cry raised, this was made to sound like a huge problem. In fact, there are many huge problems in ISDN pricing, and the FCC's Customer Access Line Charge is a pittance by comparison. What should ISDN cost? It's a general principle of rate-making that the _price_ for a regulated monopoly service -- and that's what ISDN is -- should reflect the underlying _cost_ to the provider. That's what happens in a competitive market by the natural forces of economics, what Adam Smith called the "invisible hand". ISDN is, after all, a telephone line. It's just like any other phone line except that it's digital instead of analog. While analog telephone line rates today are not generally cost-based, it's quite possible to separate out the _difference in cost_ between ISDN and analog. This was done in considerable detail during the Massachusetts ISDN tariffing process in 1992. NYNEX/New England Telephone had to file exact cost deltas for ISDN services, unbundled, and the ISDN tariff is a set of deltas to POTS (Plain Old Telephone Service). That's a sensible approach. There are problems with the tariff but the cost studies are very useful. Compared to POTS, and based upon certain demand estimates that I suspect weren't quite met, ISDN costs about $7/month more than POTS. That's for a 1B+D line, speech bearer only, and it only is concerned with the Non-Traffic Sensitive (NTS) rate components. Usage is in different tariffs. Based on the cost, the MA tariff for ISDN 1B+D is $8/mo over POTS. The cost of a second B channel is well below the tariff price; they make a nice margin charging $5/month. This makes sense: There's almost no NTS cost incurred by turning on the second B channel, unless it's foreign-served. (That's also in a different part of the tariff.) I do suspect that NYNEX loses money on the $75 installation charge differential, but then they seem to do a Keystone Kops routine every time an order is placed. (To be sure, they're getting better at it. New services, such as 500 numbers, tend to be tricky to get going.) So what do telcos charge for ISDN? In the case of PacBell, it's pretty reasonable: 2B+D residential is around $24/month plus CALC. The only gotcha is that ISDN is measured service during the daytime, while residential POTS can be flat rate. That's bizarre, and makes POTS more appealing for heavy daytime telecommuters. It has been shown in separate studies that peak-hour local usage costs much, much less than the penny a minute that PacBell charges for both speech and data bearers. On the bright side, speech and data are at parity. And PacBell's installation charge is in part waived at 1/24 per month. Now we turn to, say, Bell Atlantic. Some BA jurisdictions don't even have residential ISDN! Business usage is all measured. Clearly, their priority in deploying ISDN so widely has been to sell Centrex to large business. (Intra-Centrex usage is, of course, free.) They do sell bulk usage plans, but they are all very costly. Again, it's a good incentive for the typical residential netsurfer to stick with POTS. Bell South takes a different approach. They have lots of flat-rate territories. Atlanta's a wonder: Even businesses can get flat-rate lines with a local call extending clear across the metro area! This is one Bell company that must have cried all the way to the bank when their regulators told them to stick with flat rates. (Bell South is very profitable.) So what's their ISDN rate? Roughly double the POTS rate. The POTS rate is quite high because it's flat rate over a wide area, so residential ISDN is over $50/month. Sure it lets you make a 128 kbps call, but if you only want 64k, it's quite a premium over residential POTS! The so-called "value of service" for 2B+D is considered to be double POTS (a common European tariff, btw, where ISDN BRI is priced at 2x POTS), but in reality the rate is there to cover assumed heavy dual B channel usage. Use only 1 B channel and you're not getting your money's worth. I think of the second B channel for many (not all) users as as a "pack", a high-profit item like the unwanted gimmicks the car dealers make their profits on. Southwestern Bell's monthly rates aren't the outrage, but with Texas residential installs running over $500, who wants to pay? A three-year buydown helps a little. And then you have the cases where data bearer usage is priced way above speech. This is the case in most NYNEX land, and I think Ameritech. It encourages the Data Over Speech Bearer Service hack, to be sure, which a handful of vendors are scared to support. Since hardly anybody knows about DOSBS and telco sure isn't going to tell you, potential ISDN customers are scared away by outrageously high usage charges. Here in Boston, for instance, a LOCAL call of 8-16 miles costs 5.5c/minute under the measured service tariff that applies to all ISDN data bearer. But a 75 mile intra-LATA toll call at night is only 3.6 cents a minute! Within 8 miles, it's only 1.6c/minute, but residential modem usage is free. Encouraging, no? I won't tell you how much it costs in NYNEX or some other places if you happen to live between 18 and 34 kilofeet from their widely-scattered central offices. My computer cost less than just the install charge. Again, kudos to PacBell for realizing it's their problem and averaging the cost. This really discourages a lot of potential users from getting ISDN. Those are the sorts of tariff problems that give ISDN a black eye in the United States. These are the sorts of prices that invite cable TV companies to try to get into the act. These are all decisions made by state regulators, in cahoots with the monopoly telephone companies. Next to this, the FCC's <=$6/month CALC charge is a drop in the bucket. Let's focus our attention where the real problem is and not get distracted by minor-league details. Fred R.

Kimberlin <0004133373@mcimail.com> Subject: Sesquuicentennial of Digital Communications? SESQUICENTENNIAL OF DIGITAL COMMUNICATIONS? This year seems to mark the 150th anniversary of electrical digital communications without fanfare. Traffic on the "Information Highway" multiplies at an astonishng rate as a myriad of methods to deliver wideband communications are deployed. But few practitioners have a solid reference point from which it all began. That date could well be argued as April 1, 1845 when Morse's telegraph was opened for public message conveyance between Baltimore and Washington. For the British part, the date of January 1, 1845 could be argued. That was the date on which, after a lackluster period since installation in 1838 along the Great Western Railway, the Cook & Wheatstone telegraph was used to alert London police to the arrival of a wanted criminal on a inbound train. While examples of earlier telegraphs abound, Morse's system first combined use of direct current, electromagnetism and serial transmission. Further, the "Morse code" developed by Alfred Vail for use in Morse's system contained the rudiments of today's "information theory," with its principle of using the shortest sequence to send the most frequently occuring characters. For a century thereafter, the principles upon which today's modern digital binary transmission developed, first with electromagnets, mechanical commutators and electromechanical relays, then after development of vacuum tubes, by electronic means. The "break signal" or "reverse interrupt" of basic data communications arose in the beginnings of telegraph operations. Formatting of paper telegrams with an address header, routing instructions, message body and error check included in the message has evolutionary descendants in today's packet protocols. Early on, telegraphers discovered further compression of data could be had by sending short numeric sequences in place of common phrases in messages. The well-known "73" of amateur radio has roots in wireline telegraphy, while an entire numeric code called the Philips Code saw common use in press transmissions. The principle of Time Division Multiplexing saw its first practical use in Baudot's multiplexed telegraph several years before Bell's telephone. So-called "ARQ" automatic error correction came about when telegraphy was applied to HF radio between nations. Even multilevel phase modulation schemes were used by telegraphers before the era of "modems." About fifty years ago, the era of semiconductor electronics burst forth, making microminiaturization possible. Still, every digital pulse we send down a transmission channel operates in the same fundamental way as did the original electromechanical telegraph of a century and a half ago. If not 1845, when did practical everyday digital eletrical communications begin? ------------------------------ From: fybush@world.std.com (Scott D Fybush) Subject: 203/860 Line Determined Organization: The World Public Access UNIX, Brookline, MA Date: Wed, 29 Mar 1995 03:52:51 GMT Connecticut's regulatory officials have drawn the final line for the 203/860 split, and it will look like this: In general, New Haven and Fairfield counties will stay in 203, while the rest of the state (including Hartford) will become 860. The two exceptions are: The town of Sherman CT, which forms a wedge at the NW corner of Fairfield County, across the state line from Pawling NY, will go into 860. I don't know what NXX that is, as I can't find Sherman on a 1990-91 list of 203 NXX's. It may be that Sherman is served out of the exchange in neighboring New Milford, which is in Litchfield County and will become 860. And Woodbury Telephone Company's territory, which straddles the Litchfield-New Haven county line, will go 860, even the part in New Haven County (Southbury, I believe). Permissive dialing starts in August 1996, mandatory in October 1996.

Some feel it's needed to avoid accidental outages or service degradation due to user or maintainence actions. Others think good planning before installation will help avoid mistakes. We know conduit will help cut down on RFI and EMI, but use of shielded cable (installed correctly) should take care of most interference. Do the benefits of using conduit out weigh the costs?

The number of entries is less than the size of the book would suggest, since many items appear more than once, in different topic sections. The material is thus very far from being complete, while certain areas contain items that are only very loosely related. (Travel, for example, has entries on history and government resources.) The "multiple listings" are a good idea, since neither the table of contents nor the index may help, at times. (The Internet Coffee Machine, for example, is not listed in the index, nor does it appear under "Food and Drink", although an image from it does. The actual entry is listed under "Cyberculture".) All are "reviewed" at some point in the book. These comments are generally only a short paragraph, but are worth looking at. The multiple listings point to the one review. (Project Gutenberg actually gets two separate reviews: the later one does point to the earlier.) The entries are mostly standardized on URLs (Universal Resource Locators). There is an explanation at the beginning of the book, and an explanatory "Unraveling the URL" sidebar which recurs throughout the book. The emphasis is on World Wide Web and Gopher entries: others are not given unless there is no WWW or Gopher pointer. copyright Robert M.

The Economist chronicles this peculiar technological feeding frenzy in its Jan. 28, 1995, issue ("The Third Wire," pp. 62-63) but questions whether these companies have what it takes to compete with the likes of Microsoft and AT&T. Aside from money, railroads and utility companies have rights of way but lack much else that is necessary to survive in an increasingly competitive market, the magazine explains. Many overcome their shortcomings by forging alliances with telecom companies. But will this be enough in the end? "Fortunately for the utility companies, however, telecoms alliances remain all the rage," the magazine concludes. "An alliance with a firm such as Sprint or Bell Atlantic can bring a utility expert knowledge of the technology and the market, as well as someone to share the cost of new networks. All the same, utility shareholders would be wise to watch their wallets as their company managers enter the multimedia snakepit." A sidebar to the main story lists utility companies around the world that are entering the telecom market. ----------------------------------------- This story is republished with permission from the April 1995 Cybernautics Digest, a monthly summary of reports about converging information technologies.

My understanding is that it would allow end users to chose their carriers without having to dial extra digits. Could someone elaborate and define it to me more clearly? Also, if it provides the end user more choice, why is it being opposed by wireless resellers like Nationwide Cellular Services, Inc.?; Additiotionally I would like to find out a thing or two about the business of "reselling" airtime (wireless and wired) that has been purchased wholesale from a primary carrier: a) What are the mechanics of the business?; b) Who maintains customer accounts after a "resale" has beenm consumated?; c) What are the margins like (from those who are/ have been in the business)? Any and all replies will be greatly appreciated. Jerry okoko+@cmu.edu [TELECOM Digest Editor's Note: I do not know where you got your data from, but equal access has been the law in this last for several years. I do not know of any of the OCCs (other common carriers, meaning all of them other than AT&T) who objected to equal access. When I first read your message I thought somehow it had gotten recycled from sometime back in the 1980's. Are you thinking of something different than me? Regards some of the cellular carriers, they force their users to call out on certain long distance carriers they have cut deals with. I guess legally they have that right. When equal access was debated in the USA several years ago the other carriers not only did not resist it, they demanded it!

I understand that Mac > software has these resource fork thingies, which complicates things. As you hint, the exact format of a Mac file cannot be represented on a PC or UNIX file system. A Mac file has actually three constituents: The data fork, the resource fork, and the desktop information segment. There are three conventional approaches to this dilemma: 1) "Appledouble": Represent the file by three different files in the Unix or PC file system, with coordinated names. The data fork goes in "xxfilename", the resource fork goes in ./.resource/xxfilename and the desktop part goes in ./.desktop/xxfilename . This approach is used by some AFP file servers and some MacIntosh system emulators. It suffers from several weaknesses: - the filenames are subject to the host file system's restrictions which is visible to the application on top. This may be mitigated by adding the "real filename" to the desktop info. - everyone has chosen different conventions for naming the components. (i.e. the resouce fork might be in xxfilename.rsrc in some systems, or the hidden directory might have another name) - it is very easy to get the components separated (rename the file, forget to rename the hidden pieces or accidentally renaming them differently) 2) "Applesingle" - combine all three pieces in a single file with a header describing at which offset each part begins. Apple has defined the complete file format. Used by several network backup systems (The Fetch netork file transfer utility will pack/unpack so that Mac files are stored in this format on a networked Unix/DOS host) - not suitable for access in-place via NFS etc; cannot rewrite/exand the resouce fork or desktop segment without destroying the whole file or requiring a re-pack of it.) - I am not aware of any Mac-resident program to unpack one of these if you have it on a Mac disk in a binary data-fork-only file. 3) "BinHex" will pack a Mac file into a single, fully printable/e-mail-able file and unpack this as well. - same disadvantages as Applesingle. > I believe you need the program StuffIt (or equivalent) to unstuff these > files with extensions .hqx). So I also downloaded UnStuffIt.1.5.bin. I'm > not sure what the extension .bin means. Does it mean it can unstuff > itself by doubleclicking on its icon? The correct program to unpack "HQX" files is BinHex. Stuffit will do it as well. If the unpacked file has a name ending in .sit, then it is a a Stuffit archive. It might also be a .sea file: Self-extracting archive. (Usually packed with Stuffit.) The .bin file is probably an Applesingle file. If you were FTP-ing it to the MacIntosh using the "Fetch" FTP client, then it would be unpacked and stores in the unpacked form on the Mac's disk. > One option would be to get a Mac telecom program and move my 14.4 > external modem to the Mac whenever I needed to download Mac programs.

Why is an RBOC's inclusion of a bill insert or it's use of it's customer list for advertising worse than the ads included in the bills of almost every company in America? Why is it worse than the coupons (thinly disguised ads, really) on the back of grocery store register reciepts. Aren't those poor old grandmothers subsidizing that too? And gasoline bills, cable bills, etc., etc ... Does anybody know of any company that NEVER uses their revenue to try to generate more revenue? The game is called BUSINESS. Does anybody really believe the hype that residential phone service is this monstrous revenue generator that supports all the other projects of the LECs?? Does anybody really think that ATT et al want to get into the local phone service business because there's so much money in it? Does any one want to provide JUST telephone service? The IEC's only interest in local service is as a means to avoid access charges to the LECs. The cable industry's interest is in getting a share of the access money and to be able to sell other high value products that granny couldn't afford and probably wouldn't want anyway. Does anybody really think Time-Warner will give away service to granny because they hope to make money off her kids? Revenue always comes from somewhere, so imagine this scenario: MCI is allowed to provide local service. Figuring that selling local service at a lower rate will encourage people to use their service, and hopefully their LD service as well, they price it signifacantly below the old LECs rate, maybe even below their actual cost. Sprint decides not to get into local service and instead prices it's services very aggresively. MCI's local customers decide Sprint's LD rates are better and start shifting. MCI starts to lose money. Will they try to survive by cutting prices on one product or raising prices on another? Cut back on maintenance or hold the line by laying people off? My point is that every entity is in the business for the money. And like car dealers, they'll make their money on one side of a deal or the other. The general public will not be thrilled to have their local service phone bill becoming a ping pong ball, going up or down as suits the needs of a provider whose main interest is in some other part of the package.

In 1989, area codes were limited to N0X/N1X form and were getting to be in tight supply. The shortage was relieved only recently with area codes being allowed of NXX form, and there was a delay in such relief because of equipment having to be reprogrammed for the generalized area codes. Now there are lots of area codes available, so it should have been rather easy to grab two of them (630 and an unannounced one) for a split of 708. The biggest concern now is the people getting the early NNX area codes (remember hearing about the problems people on the east coast had when they had to give an N0X or N1X prefix in Los Angeles area to an operator?). I don't know what notes ever existed for the UK network, but the courtesy of "ten year wait" was also not followed for people in London and suburbs. 01 split into 071 and 081 back in 1990, but now those areas are becoming 0171 and 0181 respectively.

I guess you're just missing activated Ericsson Mobiden modems with the applicable software. My understanding of the Ericssons Mobitex radio packet switching network (that RAM uses) is that it just wraps your packets inside its own. Then strips off these bits when leaving the system. I'm not sure where you can purchase these modems in the US, but a quick call to RAM should do it. If both ends are in the same base station coverage area, your turn around time should be quick as each base station can operate autonomously. However, if your planning on using it in different metropolitan areas, be prepared for a delay :-( If you should need more info, I know a Mobitex Guru who has implemented many such systems.

What sort of encryption algorithm is used and how > are encryption keys handled (programmed once into the phone and known > by the carrier, or regularly updated by some secure password > transmission algorithm?)? GSM uses something called A5 for mobile-to-base encryption (all wireless traffic). A5 was supposed to be very top secret and known to about 20 people, till source code reverse engineered from hardware diagrams anonymously posted in a brown paper envelope was distributed on USENET. A5/1 uses 40 bit keys, which can be broken easily in a few days. As it is essentially used for on-the-air traffic only, and is not easy to break in real time, that may not be a problem. GSM uses a challenge-response protocol, not an ID query/transmit sequence, to authenticate the caller. This protocol is implemented on the CPU of the SIM card, unique to every caller, with a reprogrammable PIN (like an ATM card). An SIM card can be inserted into any GSM phone, which retains that caller ID as long as the card is inside. This, together with the challenge-response protocol, makes it very difficult indeed for anyone to snarf caller IDs off the air. Some of your other questions were not relevant to GSM. Other digital cellular systems are pretty redundant IMHO. > 1) Do people on this forum believe digital cellular will eventually replace > analog cellular? How soon? Most countries in Europe and Asia use digital cellular, specifically GSM. The fact that my cell-phone in India will be GSM means I can be automatically reached at the same number anywhere in the world where GSM is operational with only minor administrative, and no technical, hassles. > 2) Currently, analog cellular phones are often available free with one > year service contracts, but digital cellular phones are expensive.

A top-of-the-line GSM phone, such as Nokia's 2110, can send short fax messages and e-mail. No, digital cellular phones are probably going to remain expensive (or not free) for a long time.

Sounds as if you've a typical LAN/WAN/LAN problem and that a dedicated DS0 circuit with bridges could be a solution. Well of course there are many different scenarios but a suggestion would be: 1) Dedicated 64 kbit/s circuit USA to Europe about 2500 per month for 1/2 circuit of course this depends upon where you land in Europe. Your US office pays 1/2 charge and the foreign office pays 1/2 the charge. Actually the rates will be much higher on the European side. To use an example, say you have an office in New York City and an office in London, you can get a circuit between MCI and BT for about 6K per month. 2) You purchase a bridge that has both LAN (ethernet) and WAN (64 kbit/s) connections with two voice modules in each bridge at each end. 3) You can transmit data all day and night and when you want to call across the pond, just pick up a phone. Maybe use the other phone module for fax. Then you have a phone and a fax and data all multiplexed over your bridges at 64 kbit/s. OR You could have all the offices on the Internet paying local charges for ISDN 1B channel at 64 kbit/s, use the IPHONE from VocalTec and Email for faxes, you transmit all the data you want for only your local ISP charges and talk as well ala conference style. BUT The neatest way is to have a Ku-Band VSAT 2.4 meter Earth Station at each site and do ISDN 2B+D all the way and enjoy voice, data and video as well.

I wonder what effect this will have on small providers who > rely in PacBell for their services. That this is happening is no surprise. The RBOCs believe they have the "license" to serve all of the telecommunications needs of local businesses and consumers. There is a company down in Atlanta which has been pushing this concept from the standpoint of the RBOCs will "become" your Internet Service Provider and all of the existing Internet Service Providers will become, in effect, "Long Distance Carriers" who are restricted to carrying Internet Traffic over LATA boundaries. That company is selling Internet Service Software that complies with the "equal access" provisions of the Modified Final Judgment. If you add that to the fact that, in accordance with a recent posting from the Electronic Frontier Foundataion, the RBOCs have paid off enough senators and members of Congress to push through an amendment to the telecommunications act that says, in effect, if you want to connect to a larger information provider via the phone lines, you must do so via an interface provided by the phone company, and if you want to connect via the cable tv cable, you must do so via your licensed cable tv supplier. The only thing it does not prohibit is your receiving service directly via some radio frequency service, but the RBOCs and the cable TV guys believe that the lack of frequencies and the FCC licensing procedures will create a natural barrier to your getting service via "radio." So, there is a valid reason to have concern that you might eventually be prohibited from selecting your Internet Service Provider and connecting to it by way of anything other than something "approved" by the local RBOC. On the other hand, Pac Bell is pushing for full deregulation of the California telecommunications market "as soon as possible," while GTE is dragging its feet as much as possible. One of the ways in which Pac Bell can convince the California PUC that it should grant full deregulation is to show that there is "substantial competition" in the local telecommunications market. In this view, Pac Bell does not actually intend to monopolize the market, the way that it does with local voice calls (withing 12 miles of your central office), but instead, Pac Bell is trying to enter a market for local telecommunications traffic for which it would NOT be the "market leader." It wants to do this as part of its own deregulation strategy. Which actually happens depends on whether the pricing strategy of Pac Bell is designed to drive the Kaiwans and Deltanets out of business. The guy from Atlanta hinted that, before long, the "local" Internet connectivity would be available from your friendly RBOC for $5/month for home use, similar to what the RBOC charges for voice mail now. However, because of "equal access" considerations, you would somehow be required to also have a subscription with a "Long Distance" Internet Service Provider who would connect at the "back end" of the Pac Bell system. Of course, this violates the fundamental price structure which has evolved for the Internet, which is once you are connected, communicating is "free" world wide. What actually is meant by the Pac Bell announcement may not become apparent for quite some time.

In the mid-1980's, I worked for ROLM as a PBX installation manager in Chicago. City of Chicago code required all telephone wire to be in conduits. Outside of the city, however, we could run plenum wire. I never saw a quality difference between conduit and plenum wiring. We always thought that the Chicago code was just another part of the city's full employment plan for the IBEW/CWA membership.

Since most of the military establishment uses X.25 transport as the undercarriage for their Internet networks (MILNET and its cousins) many companies have implemented TCP-IP stacks that will use an X.25 network connection as a network interface. Including Sun Microsystems, TGV, Wollongong, Digital Equipment and others. This approach has two problems: 1) It is expensive. It is often less expensive to get a 56 Kbps leased line between two points than to get two X.25 network access lines installed, and then you still have to pay per-packet charges to the X.25 network. 2) It usually has horribly bad performance. We used to be able to get about 1200 bps on a virtual circuit on a 9600 bps access line. Makes 14400 bps dial-up look like a dream. ... Frame Relay was invented to address both of these shortcomings.

How soon? The cellular company I work believes that eventually digital will replace analog but has committed analog service until 2003. They believe this because digital will allow more capacity, lower power consumption (more talk time) eventually better audio and allow a full range of new features (like CallerID). They are also looking at the new PCS market and the possibility of have dualmode phones (i.e. GSM\TDMA) or having both marketswith one standard capability. > 2) Currently, analog cellular phones are often available free with one > year service contracts, but digital cellular phones are expensive.

Unless there is another concept that is represented by SS7 in telecommunications (I do not doubt the possibility), :-) SS7 that I know of stands for Signaling System No. 7. It is a protocol with a stack similar to that of OSI (although terminology is different and also currently some layers not defined) that is used in the telecommuncations signaling network to do out-of-band signaling. ANSI defines the Standard for North America and ITU-T defines the Recommendations in the international arena. I am not aware of any such concept/ capabilities as "SS7 Programming" to string bits together in the right order (the way you described) to achieve what you would like. There may be a different way of achieving what you wanted, but that's for others to comment.

[A good comparison of RBOC ISDN rates that took a long time to write, snipped] Most of you might know that Fred and I don't agree about the FCC's proposed increase in the CALC for ISDN (Fred is FOR the increase). However, I do agree that the proposed increase is not the most substantial issue with regard to mass marketing of ISDN. However, I strongly disagree with Fred with continuing this RBOC bashing on the price of ISDN. While deregulation and market issues are of importance, Fred is considerably oversimplifying the situation by focusing on the voice services component of ISDN -- IMHO, a very significant mistake. ISDN is, after all, NOT a telephone line. It's bandwidth. And it's a sizable quantity of bandwidth that the user is free to do with in anyway they see fit (with the exception of the limitations proposed by Senator Exon's view of the world). Fred's arguement about the cost of ISDN is relevant ONLY to the voice portion. Fred is correct that ISDN voice services are basically the same as traditional analog telephone service (POTS) becuase it is only migrating the interface between the Central Office (CO) and the User from an analog to a digital connection. And, in this specific model, there are no significant cost differences. However, ISDN voice services are not much more ready for a large installed user base than they were nearly 10 years ago when ISDN was introduced. This was first due to the complications around establishing and implementating a set of standards between CO switch manufacturers. It has become more an issue of training personnel on how to program those features into each user's customized configuration, how to educate the public on what features are available and how to order them. In fact, the North American ISDN Users Forum (NIUF) has yet to produce any output related to the Simplication of Order Codes specifically for ISDN voice services and the rich features that are available in NI-1 and NI-2 systems. The reality is that ISDN is being deployed - and ordered by users - for its DATA NETWORKING capabilities. For this service to exist, a significant infrasture on the backend of the CO switch was needed in order to move the data from Point A to Point B - outside the CO. If ISDN Voice were the only issue, then the age old engineering and circuit aggregation methods for voice could have been used as well. With ISDN Data, however, there were no existing engineering or bandwidth aggregation models - or really even an infrastructure to handle them. Ameritech and NYNEX's rate structures are really holdouts to the old ISDN voice pricing structures. While these RBOC's are probably smart to have these tariffs in place as preparation to an upsurge in the ISDN Voice market although no significant tangible market delivery method exists today. Voice. In fact, its quite obvious that Ameritech and NYNEX's ISDN customers are using these tariffs for DATA in order to simply avoid the higher charges associated with 64K service. The RBOC's, in general, are still not very interested in ISDN Voice service deployment. In fact, ISDN voice is generally viewed as a complication to the sale of ISDN due to its many complications. The evidence of this is in their tariffs. So, what are you being charged for with ISDN? BANDWIDTH and the necessary local backbone that was put in place to carry it - a backbone that is still being built and that costs a considerable amount of money to engineer and install. Not the original backbone for voice services and not a migration of that voice service backbone to a digital environment. Consider this: On every Mother's Day, you expect to get a recording that says "all circuits are busy" on at least your first attempt at calling dear old Mom. We have come to accept this because we know that the local and long distance telephone companies have not built their networks to handle the quantity of calls that are placed on that specific day. But, we also know (or expect) that these same telephone companies are continuing to add service capability in order to meet demand. Thankfully, these companies have a significant amount of historical data compiled over decades that allows them to gauge the amount of service that will be necessary. Where is this history for DATA services? Does it even exist in any sizable quantity? What has really happened is that all previous expectations of service needs have been exceeded and are continuing to be exceeded at an outrageous growth rate. And, unlike voice services, you don't expect to be told that there isn't enough BANDWIDTH available for you to send Mom an e-mail message -- that simply isn't acceptable, is it? IMHO, the best comparison for ISDN is with your local Water and Sewer Company. In many parts of the country, water rationing has had to be done and prices have had to increase. These price increase are due to a lack of supply and, in many cases, the need to pay for the investments necessary to build an infrastructure to make additional water available to the growing poplus. But, we know that water shortages exist - especially when there is a lack of rain. We might complain about the rationing and the increase in pricing, but we also know that its for the good of the community as a whole. ISDN can do for the availability of bandwidth what running your lawn sprinklers for hours every day can do to a community with a limited water supply. Fortunately, the RBOC's have the ability to add more bandwidth to meet the demand without rationing supply. And, I seriously doubt that you're going to hear that you can't use your ISDN line on Mother's Day - or any other day of the year - because there's just not enough badnwidth available. But, someone has got to pay for the investments necessary to provide this bandwidth - and that someone is the users. Not very long ago, a *reliable* 300 or 1200 bps connection between two sites in the local area costs several hundred dollars per month. This was when copper wire and repeaters were necessary. Even today, a dedicated 56 or 64K circuit from one end of town to another costs several hundred dollars per month. Part of that cost is in the bandwidth backbone and part of it is in the cost of allocating and maintaining the copper connection on both ends of the circuit. ISDN provides greater capability, is more complicated because it's a switched service, and uses the same portion of that bandwidth backbone for each B channel. While I do agree that many cost related issues remain before ISDN can be mass marketed throughout the country, simply reducing the cost for the sake of it is clearly not in the best interest of the users. Not if you want to send Mom that e-mail message. We must allow the RBOC's - or any other competing service - the ability to continuing to invest in this bandwidth infrastructure for the good of our country and our new information society. Market demands will bring pricing down. But, it is unreasonable to believe that some 20,000-30,000 users that are currently using ISDN in each of the RBOC's areas come close to compensating for the investment that was, and will continue to be, necessary to provide the service -- DO SOME MATH FOLKS! Make an investment yourself! Learn about what you can do with the bandwidth. Start developing information based applications as entrepreneurs that will provide someone else a reason for getting ISDN because they need what you've got. Take the knowledge you've accumulated in your lifetime -- or for that matter good old Mom's recipes -- and put them into electronic form for distribution at a fee. In short -- PREPARE FOR ELECTRONIC COMMERCE. The RBOC's have provided all of us an ability to PROFIT from their investment and all people seem to want to do is complain about it. You, the individual reader, have the ability to make money with ISDN from your home or business with your computer on a local, national and international basis. There is a tremendous opportunity in front of each and every one of you - and if you're reading this you are so close to it, it's silly. Stop bashing the RBOC's! Instead, start exercising the freedoms you have in this society and THINK about how you personally can profit from what they've accomplished. Hint -> Quantities of information (DATA) delivered to lots of people inexpensively for which you're getting paid. If you want the prices of ISDN to drop, the best thing you can do is help create the demand for it. If you happen to profit from that, well I don't think the RBOC's would mind very much. :) Ed Goldgehn, Sr Vice President/CTO E-Mail: edg@OCN.Com Open Communication Networks, Inc.

Gilder's ideas have gained ascendance with the new Republican Congress, so he is in an important position to help shape the next decade of technological development. Yet his response to Postman's essay is hastily dismissive, and this is what is distressing. His note essentially says, "Can't stop to ponder the downside of computers because I'm too busy writing about the upside." Massive computer proliferation may well be inevitable, but this is certainly all the more reason to at least soberly question the applications and implications of the technology. Both Postman and Gilder are presenting viewpoints from somewhat extreme poles, mostly to make evocative and interesting points. Yet if the computer is not a monster, it is not global salvation either. My computer helps me pursue stimulating work based on intellectual output; someone else's is used by a low-paid data entry clerk whose keystroke output is monitored. I can press a key and send Postman's and Gilder's messages to friends and colleagues around the world for their consideration and enrichment; someone else can press a key and transmit messages designed to lure customers in a scam or to propagate hate mail. So the issue really, truly isn't the machine; it's the uses for the machine -- and as with other things we create, it will be used both for glorious and awful purposes. It will have both wonderful and unpleasant consequences. The downside isn't reason to reject the technology -- we don't stop driving cars even though they sometimes kill people -- but, following the car analogy, it is reason to weigh the dangers and do what we can to minimize them. It is precisely because academics are somewhat isolated that they can afford to ponder the philosophical implications of commercial technologies (but except for the few superstars, most academics will dispute that there is 'wealth and comfort' to be taken for granted!). Rather than write off such thinkers as uninformed pessimists, it is better to consider their contributions and use them to balance the unending stream of technological promotion.

I must agree on some points and yet find myself forced to question other's. It is true that as a race, if human kind is not moving forward, it is really going backwards. Human nature is to do it bigger better and faster than before. I do however support a slightly modified view with Mr. Postman. Where I work, online access to the InterNet is only a few months old. There is a real information glut here at the moment. I expect that this problem will pass in another month or two. The trouble with our InterNet link is it is *new* so I am receiving messages, images and even some animations on topic I really am not interested in. These are not coming from my own ramblings through the 'Net, but others wanting to show what they found. (A bit like show and tell at school?). We had the exact same probelm when the first multimedia capable machine arrived. There are only so many times you can watch 'Peter Gabriel's Steam' video. I myself learned within the first two weeks that I was killing myself with information, but only because I strayed outside my sphere of interest and understanding. Now that I focus on my three core interests of Automotive Electronic, Space Exploration and Telecommunications, I find I am viewing about the same volume of data as before, but do not feel it is too much. It seems even information has a phsophometric weighting principle. Finally, IMHO all technology is a means to an end. If I choose to work hard, I can design a replacement for the current carburettor using a slide rule and a piece of paper. I can also do this using a computer. Each has a different learning curve associated with it. Neither is better at focusing me on my goal than the other and it is that focus which prevents information glut (independant of the fact that one will be faster then the other). Here I do agree with Mr. Postman, the computer can not be the key to Nirvana but I believe that this is due to the simple fact that once the computer was invented, Nirvana in the eyes of humans became different. It is also not the cause of information glut. It is simply the platform from which we *choose* to become info junkies. Computers will not cure the world, but the people using them will!

As well as what everyone else has written, you might like to note that a .hqx file is a text file (in the same way that a uuencoded file is). So if it won't fit on a floppy, you can split it on the PC and recombine the chunks on the Mac. This does presume however that you have a utility on each machine that can handle such a large file, which rules out most text editors. I regularly do what you want to do -- download on to a PC and then transfer by floppy to a Mac for decoding and uncompressing -- and have no real problems with it. But I've never come across a .hqx file that wouldn't fit on a single floppy.

That company is > selling Internet Service Software that complies with the "equal > access" provisions of the Modified Final Judgment. No, Bill. That is not at all what I said to you via e-mail during our off-line discussion nor what our company has been doing for over one year. And we're not selling any software. We are a data communications company that has spent the last year engineering and operating an IP/CO (Internet Protocol Central Office). What I TRIED to relate to you is that the LOCAL Internet is a different pricing and cost model than anything that has to do with carrying bandwidth out of the area (to a NAP) and back again. This has nothing to do with our service here in Atlanta -- which is a LOCAL Internet. We are compliant with the MFJ but not for the reasons you state. We are compliant with the MFJ because it makes the most business sense. We are the only company in the US that is *operating* in a manner that provides for EQUAL ACCESS to any number of independent Internet Backbone Connections. We do NOT require the end-user to purchase the Backbone Connection and LOCAL connectivity in one bundle. A user may select LOCAL Internet Service only or LOCAL and WorldWide Internet Service and *then* select the provider of that WorldWide Internet Service of their choice. Because we are compliant to the MFJ, we are able to work much more effectively with the RBOC's - a logical relationship given the current makeup of the telecommunications industry. > So, there is a valid reason to have concern that you might eventually > be prohibited from selecting your Internet Service Provider and > connecting to it by way of anything other than something "approved" by > the local RBOC. More paranoia as a result of ignorance. What will result is simply a matter of marketing economics. Here in Atlanta, the LOCAL internet is being built to handle at least 500,000 customers over the next two or three years. The issues related to handling these customers on a LOCAL Internet are quite different than trying to determine how much bandwidth is necessary back to a NAP to serve all these users. Since NAP bandwidth is not a component of the LOCAL Internet costs model, the pricing models of connectivity to the LOCAL Internet are considerably less than typical (worldwide) internet connectivity. > The guy from Atlanta hinted that, before long, the "local" Internet > connectivity would be available from your friendly RBOC for $5/month > for home use, similar to what the RBOC charges for voice mail now. > However, because of "equal access" considerations, you would somehow > be required to also have a subscription with a "Long Distance" > Internet Service Provider who would connect at the "back end" of the > Pac Bell system.

To translate, Bill is saying that BANDWIDTH and CONNECTIVITY to a NAP is FREE. So, no matter how much bandwidth any user needs to get the performance they will want in order to be productive, the fundamental price structure today is FREE BANDWIDTH. Hogwash! What pricing structures are in place today by MOST Internet Service Providers is a formula that says: "Get as little backbone bandwidth as possible and let as many connections use it that pay me money without regard to any level of throughput performance and bandwidth management." This is not FREE bandwidth, Bill. It's NO Bandwidth -- or at least no significant amount of bandwidth. They incorporate a fee for the least amount of bandwidth that is necessary into their scheme and then give you a bundled price that does not break out the components. The problem is, they don't tell you how much bandwidth they have committed to each end-user's connection or at what point they will upgrade their connection speeds to the backbone. I would also venture a guess that most ISP's have no idea on how to effectively measure or calculate end-user bandwidth requirements to begin with. More to the point, the worldwide Internet is made up of many independent networks. Most of the hype is centered around how little bandwidth there really is to the Internet in general (no more than a T-3 between networks today). What is virtually unnoticed is that the "last mile" -- the point of connectivity for the user -- is the one network that's not really built today. It is this network -- the LOCAL internet - that will utimately serve our daily networking needs. It's the LOCAL internet that will provide connectivity between home and (local) work or parent/student and school. It's the LOCAL internet that we will use to order our groceries, make our restaurant reservations, and look up our children's homework assignments. None of these examples NEED bandwidth back to the Worldwide Internet. Adding -- strike that -- REQUIRING that the end-user PAY for bandwidth that will not be used in over 80% of data communications places an undue cost -- and in most cases *performance* -- burden on that end-user. Actually, several splinters of a LOCAL Internet exist today in nearly every area. The RBOC's Local Frame Relay Cloud is an internet. SMDS service offerings are internets. Local Fiber Rings providing Native Lan Interfaces are internets. ATM -- when deployed -- will be an internet. However, these are all singular access methods that are not accessible to each other or to the users that need only switched (on-demand) connectivity to these internets via ISDN or traditional analog modems. Our service, IPConnect (sm), provides a meet point for any or all of these connectivity methods. The service, and the IP/CO platform, has been designed to be licensed, operated, managed and marketed LOCALLY in every community it serves. Moreover, IPConnect enhances the services already available from the LEC's by providing a high volume, low cost shared public access destination. This is of significant assistance to the RBOC's (and other LEC's) as it provides the most flexible and cost effective method of establishing and maintaining data connectivity in a high volume environment. Now, when you want to go to Moscow or anywhere else on the Worldwide Internet, you can. What you will pay for that destination will be dependent on the (worldwide) Internet Bandwidth Provider (IBP) you select. You are free to select the guy down the street that's got a Factional T-1 connection who will only charge you $15.00 per month for unlimited usage. Or, you are free to select another company that guarantees you throughput performance through multiple T-1's, T-3 or an OC-48 ATM connection (wouldn't that be nice). But whichever IBP you select, your costs for LOCAL Internet connectivity have not changed. And, it's not likely to be the RBOC's that will "bring" this to you, Bill. It's entrepreneurs and other local business people physically in your community that serve only your community (no ivory towers here). Since, however, this only helps the RBOC's significantly increase the installed base of their digital data services (and therefore reduce cost), you are likely to find them very supportive and of great assistance in promoting our service and its capabilities. I know, at least, that we've found BellSouth to be that way.

On the other hand, if you know who > committed the fraud, or did not act in a reasonable way to mitigate > the losses due to the fraud, then you might very well be responsible. This touches on a subject which I have never seen fully addressed: In all the cases where fraudulent long-distance calls were made using stolen card numbers (e.g. via shoulder surfing at airports), there is no question about _who_ was called; the number dialed by the guilty party is on the bill. Certainly a lot of these numbers are in foreign countries, but has anyone ever attempted to collect from the called parties for the fraudulent calls? On a single call basis, the effort is probably not worth the expense, but when so many fraudulent calls are going to certain countries that access to those countries is being denied by certain carriers, as I understand it, I have to wonder whether some international cooperation on this problem might be worthwhile, especially for numbers called more than once using stolen accounts. Has this been considered? Andrew C. Green (312) 266-4431 Frame Advanced Product Services 441 W. Huron Internet: acg@frame.com Chicago, IL 60610-3498 FAX: (312) 266-4473 [TELECOM Digest Editor's Note: The trouble with attempting to collect from the recipient of the call is that it completely goes against the grain of how the system operates. What are you supposed to do, be afraid to answer your phone when it rings for fear that later on you might be required to pay for the call? Unlike other utility services such as electricity or the water works or gas works, the telephone is different. Your usage of water, electricity, etc has no bearing on anything anyone else does. With the phone on the other hand, it takes two to tango. Your use of the phone requires a cooperating person willing to do the same thing at the same time. Since you can control when/who you call, but have no control over when someone calls you, the system is set up so the one making the active gesture pays; the passive recipient does not pay unless he agrees to do so. Now in the past -- maybe still today -- telco does try to trick the recipient into identifying calls which 'fell out' of the billing system into unidentified suspense ledgers. It used to be so cute: (Bell Rep): Hello Mrs. Jones? This is Mrs. Smith at the phone company. Sorry to bother you but we have a problem. You got a call last month from someone in Kansas City. It seems our operator somehow accidentally wrote down the wrong number to be billed for the call; (forgot to write down any number at all, etc) ... we were wondering if you could tell us who you spoke with so we can get the billing corrected. (Mrs. Jones): Oh, you mean my son Fred! Such a good boy, and so smart with computers! (Bell Rep): Thank you, Mrs. Jones. We'll see that the billing gets fixed, and we will tell our operator to be more careful in the future. What they attempt to do is prove the recipient of the call had knowledge of the circumstances. Smart phreaks know you don't ever use a phraud card to call anyone who knows you personally; you use them to call radio station request lines, hotel switchboards, recorded announcement lines, etc. Then when the investigators are calling around, trying to clear the suspense ledger, they just keep reaching dead ends. Now and then they reach someone like Mrs. Jones -- a sweet little old lady who runs her mouth off -- and afterward the investigators chuckle about how 'the old bitch doesn't know it but she bought her son an indictment by a federal grand jury ...' Such a good boy! So smart with computers! Would you want them calling *your mother* to ask her who she spoke with last week in Chicago, or your employer, or your non-phreaking friends? Would you want to explain to your family or friends why, if they got a call like that from a telco they should not answer honestly? About ten years ago when General Motors got hit with fraud up the kazooey -- a million dollar's worth -- on their dialup WATS extender lines they took one of the clerks and had her sit there and call every single recipient; everyone who got called through that WATS extender. There were thousands of calls since phreaks all over the world had been advised in bulletin board messages about the GM network and how to dial into it. Ditto 'Unitel'; the United Air Lines internal phone network which connects airport facilities all over the USA via three-digit tie-line codes, then dialout with '9' from the distant centrex or pbx whose tie-line you grabbed. They did the same thing; sat there and called everyone who had been called; plenty of people had lots of things to tell them, mostly unwittingly, but now and then on purpose and vindictively. When they find someone who over and over and over again seems to recieve 'this kind' of call, then they start to squeeze a little harder. Unless they can prove the recipient was in on it they can't make him pay, but they sure can make life miserable.

Date: Thu, 30 Mar 1995 04:12:22 GMT Organization: SkyPoint Communications, Inc. Does anyone know of any instances of fraud happening on digital cellular phones? I'm just wondering if the criminal element has reached a sophistication to clone these phones? If the cellular industry is losing so much money on fraud, and if criminals cannot defraud people with digital phones, then the cellular industry should find it worth it in high crime areas to subsidize digital phones for all customers. $1 million a day could buy a lot of digital phones! Let the companies put their money where their mouth is if they are so worried about fraud. Shawn Gordhamer shawnlg@skypoint.com [TELECOM Digest Editor's Note: I dunno ... has there been? Does anyone know yet? You are forgetting one thing though Shawn. There is what is sometimes called the politics of cellular fraud; sometimes I think its more fun to talk about than do anything about. I suspect a few cell carriers must feel the same way. Those big million dollar a day losses can be quite helpful during this Holy Season of the Year as we sacrifice not only for Lent but for the Internal Revenue Service as well. As we walk the stations of the tax collectors, local, county, state, and federal, pausing at each to reflect and meditate on our numerous bogus declarations from the year before and to seek Divine Guidance from H & R Block on how to obtain a Tax Refund Anticipation Loan, we need to remember that million dollar per day losses do add up nicely and come in quite handy as we humbly beseech the tax auditor to celebrate Passover this year by passing us over for another year. If a million dollars per day is not enough sacrifice to Her Holieness, the current IRS (where the S means service!) Commissioner, then next year we double the rates to our customers so we can have two million dollars per day losses and see if that satisfies those greedy high priests. In other tax news, the Internal Revenue Service processing center in Martinsburg, WV burned down a few days ago. Seriously. They're not sure how it happened (arson was ruled out) but it was a big blaze and the whole building was pretty well destroyed. Employees on duty at the time had to be evacuated by the Fire Department, the whole works. The Commissioner noted in a press release that 'this will cause some administrative problems for us this year ...'. But they had an emergency re-location effort and expect to be back in operation in Martinsburg soon, with minimal disruption to their annual festivities. You readers who worship at the throne ... err ... file via the Martinsburg center, needn't be alarmed, or rejoice either for that matter. All Hail the Power of microfilm and backup tapes stored off premises. Such good servants! And so smart with computers! They'll be ready to 'serve' you again soon.

While I realize the need for 'user profiles', I can't help but shudder everytime I hear about them. Primarily because, I am concerned over how this information can be used. Does your company share these 'user profiles'? Or, are they for internal use only? Do your customers know that you keep their calling patterns? Or do you collect this information on the sly? If they do know, do they have the option of subscribing to this service? Or is it imposed? So much data is being collected on each and everyone of us that it is only a matter of time where every action will be tracked, collected, and dissiminated. Again, I understand the need. It is valid, fraud hurts us all. My concern is can (not if) the 'user profiles' be accessed by an outside party? If so, what steps are taken to protect your consumers? Do you notify them of inquiries? (such as Transunion, Equifax etc... are required to do?) I am not directing this at your company in particular.

I'm trying to make some tests for a radio link between two PCs with the help of two HF tranceivers which support only half duplex channels. The problem that I have is that the modems key the transmiters according to the state of the RTS pin of the RS232 port of the computers. The commercial software that I tried so far, set RTS active the moment they start to run and do not deactivate it when they have nothing to send.

I'm tempted to make some sarcastic comments about Ed's inveighing against the use of non-English languages in America, the merits of SNA versus DECnet, or something else irrelevant. After all, he entirely missed the point of my article. I was NOT writing about ISDN VOICE service at all! I was primarily addressing the fixed costs of getting the ISDN line installed, plus the cost of making data calls. Telephone companies try to snow people. They make it sound as if ISDN is a "new thang", some kind of high-tech thingamabob requiring tons of new technology, investment, etc. This is all high-tech buncombe. ISDN is nothing more than a patch to the interface to the existing public switched telephone network. The original network was analog, but digital transmission (starting in the 1960s with T1) and digital switching (starting in the 1970s) were added to it in a backward-compatible way. Thus the digital components, being new to an analog world, had to act analog. T1 therefore can carry dialed digits via digitized representations of touch-tone sounds, or via sampled-bit representations of dial pulses, but these are incredibly inefficient ways to use 64000 bps channels. That's the sort of problem you get in a backward-compatible world. What ISDN adds is "digital glue" at the edge of the network. The telcos already use digital glue (SS7) between most switches. ISDN replaces the nineteenth-century 90 volt AC ring and 48 volt battery with a modern bit stream, at the subscriber line, and replaces tone and voltage signaling with a message-based protocol (DSS1) on a signaling (D, which no longer officially stands for delta) channel. When a CO switch adds ISDN, it gets a few extras. It needs new line cards, which btw don't cost all that much more than analog cards. It needs "packet handler" equipment to route the D channel messages to the switch CPU, since the old line cards had only a lower-bandwidth (on-hook/off-hook counter) route. This is probably most of the $6.60/month/line that NYNEX measured in its rate case. And it needs new software. As we all know, software pricing is a tricky area. It divides a fixed cost among the estimated demand. In France, for instance, almost every CO has ISDN -- it's a standard option there the way touch-tone is in America -- so the switch manufacturers could divide it among many users. In America, the RBOCs deployed ISDN slowly, so the CO vendors had to charge more per switch to recover their investment. Such false economy ... > ISDN is, after all, NOT a telephone line. It's bandwidth. And it's a > sizable quantity of bandwidth that the user is free to do with in anyway > they see fit (with the exception of the limitations proposed by Senator > Exon's view of the world). Uh, no. ISDN IS a telephone line. An call made across and ISDN line IS bandwidth. How much bandwidth? Well, remember, ISDN is just a digital access port on the existing digital network. It uses EXACTLY the same basic bandwidth (64000 +/- <.0001) bps as any other call! This applies equally to voice AND data calls. When ISDN was developed, separate bearer services were defined for speech, audio and data. This wasn't supposed to be for pricing purposes. In America, we encode speech using the "mu law" and Europe uses the "A law", so a speech or audio call across the puddle MUST be converted. A data call MUST go clear! An audio or speech call MAY be compressed/processed/etc., but that's not ever economical for LOCAL calls, and rarely economical today for domestic calls (except on private networks). So "ISDN is Bandwidth" turns into a kind of metaphysical gibberish like so much other newage spamming the net these days. It takes a simple issue and confuses it. How is ISDN NOT the same as POTS? I've priced out the CO switch components, one by one. I've priced out PBX components. It's just like POTS only more suitable to using modern silicon components. > The RBOC's, in general, are still not very interested in ISDN Voice service > deployment. In fact, ISDN voice is generally viewed as a complication to > the sale of ISDN due to its many complications. The evidence of this is in > their tariffs. Half true. RBOCs want to sell ISDN Centrex voice, to compete with PBXs that have fancy proprietary phones. They don't want other ISDN voice; it would all compete with Centrex. But let's look elsewhere, where Centrex hasn't polluted the minds of telcos. In Germany, and elsewhere in Europe, if you have a large PBX, you WILL use ISDN PRI to connect to the CO. Why? Because ISDN PRI is easier to maintain than analog trunks or analog-style signaling over E1. PRI saves the customer AND carrier money that way. And it's just a slightly (!) different interface, after all. RBOCs tend to overprice PRI because they don't want to make life easy for PBX vendors; after all, they compete with Centrex! > So, what are you being charged for with ISDN? BANDWIDTH and the necessary > local backbone that was put in place to carry it - a backbone that is still > being built and that costs a considerable amount of money to engineer and > install. Not the original backbone for voice services and not a migration > of that voice service backbone to a digital environment. Yes, it IS the original backbone. Exactly the same. Same fiber optic pipes. Telcos may choose to dedicate some T1 channels in the pipes to "data" bearers and some to "speech" bearers, but that's not a requirement of ISDN, and it has no real cost differential, except that the data trunk groups are smaller and thus somewhat less efficient. The proof is in the pudding: Data Over Speech Bearer Service works because there is no real difference! Data bearer connectivity at 64k (rather than 56k) depends on Signaling System 7, but that's really deployed for other reasons, including faster call setup, CLASS service, easier maintenance (well, that's questionable), etc. The only time data v. speech really matters is at international gateways. And yes, some low-price IXCs do play games with voice, but modems suffer too from it. > Market demands will bring pricing down. But, it is unreasonable to believe > that some 20,000-30,000 users that are currently using ISDN in each of the > RBOC's areas come close to compensating for the investment that was, and > will continue to be, necessary to provide the service - DO SOME MATH FOLKS! Telco prices are based on an odd model: If nobody buys it, raise the price! If ISDN were priced and delivered right, there'd be more users. ISDN competes with POTS and modems. There is some price elasticity, especially for residential data users, potentail Internet-over-ISDN customers, etc. > Stop bashing the RBOC's!

Hint -> Quantities of information (DATA) delivered to lots of > people inexpensively for which you're getting paid. Some potential ISDN customers have jobs, and prefer it that way. If ISDN were limited to potential entrepreneurs, it would be as popular as, say, 1964 Worlds' Fair Picturephone. Besides those entrepreneurs need customers. Should those customers use POTS and modem banks to reach the info-for-sale,or should they use ISDN? Hint: POTS provides about 26 kbps data bandwidth at very competitive prices. Okay, now that I've pontificated enough, it's plug time.

Of the six listed, it's a sure bet that AT&T, MCI, Sprint and WilTel do. In fact, I can vouch for MCI (used to work for them). They are major players with substantial infrastructure.

Let's just say they both take care of me and in turn I service their subscribers the same as I do anyone else on the Internet. The University of Rochester -- and similarly situated institutions -- are not in the business of providing commercial Internet accounts. Your $25 annual fee would get you one or two sessions on line with AOL/CIS. Therein is the difference. For quite some time now I have encouraged the moderators/e-zine editors, etc here on Internet to reach terms of their own with the big commercial providers they deem satisfactory or else *simply cut the big guys out of the feed.* And if you know the workings of news and how to manipulate NNTP (network news transfer protocol) like I know how to manipulate it, then you can cut *any site* out of the newsfeed if you choose to do do. But it is a moot point with AOL/CIS because they both have been honorable with me. It would not occur to the big commercial providers to stiff the Associated Press or the bigtime IPs out of their fees and their lawyers would counsel them it was unwise as well.

Do other users of Usenet newsgroups have to pay? If not do they pay voluntarily? If so do the newsgroups have a set pricing structure? Thanks, Tim [TELECOM Digest Editor's Note: See my comment in the message before this one. Traditionally Usenet has been 'free'. There is no price for the newsgroups. But in the past -- I mean several years ago -- Internet accounts were 'free' also. Then the commercial services started tapping into the feed but they chose to make their subscribers pay for Usenet the same as anything else they offered. Even that was okay by me when the traffic was minimal. Now that the commercial services have come to rely heavily in some cases on the entertainment value of Usenet for their subscribers, it has occurred to me that they ought to treat the moderators the same as they do any other information provider servicing their subscribers. I have a large amount of traffic in and out of AOL and CIS for example. Both of those services recognize that I am at least in a small way partially responsible for their revenue. Most days I mail several *hundred* pieces of mail (i.e. this Digest) to AOL/CIS addresses, where the subscribers are charged to receive it, and charged to reply by email if they desire. Both of those services *like* the amount of traffic I generate. Now I have no delusions of grandeur, nor should any other moderator/e-zine publisher on the net. We are not the Associated Press; we are not King Features Syndicate, but we do provide entertainment and information to the subscribers of those systems. CIS and AOL both understand that.

If you have such a lead, provide the contact name at the company and we will pay a commission for the referral. Our switch is central office certified, NEBS compliant, and fully redundant and fault tolerant. The mechanics of a callback is that a caller overseas dials one of thousands of phone numbers assigned specifically to him (DNIS or DID for you techies out there). The call rings once and is drops while a database search confirms that the number belongs to Juan in Mexico City. It then dials him back to Mexico City and says "this is the callback system - enter your PIN and destination number". Now Juan is calling from overseas on U.S. dialtone. In an office environment, the system could say "this is the callback system -- transfer this call to Juan at extension 123". In a hotel or office environment, the return call can come in to an auto attendant on dedicated trunks, and then outpulse the correct touch tones to get to the correct extension (even if that country is on rotary!). "Transparent" callback means that the experience of or actual necessity for a callback is eliminated. With "continuous dial" no callback ever occurs. Instead, the U.S. dials an overseas PBX continously (advance carrier arrangements must be made!!!) on specific lines which ring continuously on specfic extensions, say extension 124. When the person on extension 123 wants to call out he uses the PBX feature to pick up the incoming call on 124 and then hears the prompt "enter your destination number. With "transparent callback boxes" the instant the box hears the international equivalent of 011 it immediately directs the call to the callback switch in the U.S. and effects the callback. The caller, who is on a form of "hold" will listen to music for five seconds maximum and then be prompted to enter the destination number, or the dialed number can be automatically stored, bridged, and outpulsed to the incoming call.

Many calls took quite a bit longer. Many times, she said, the I called once. I was shocked at the end of the call that it had taken not nine minutes, but an hour and a half. The call was free with the DOS upgrade as far as the tech's time, but the LD charges were mine. My complaint was simple: MSBACKUP under DOS 6.2 fails its own self-test procedure. I had further spent a bit of time and figured out that this only happened if I included HIMEM.SYS in CONFIG.SYS. What was really alarming about it was that the second disk of the backup that supposedly had a backup written on it appeared empty, and the backup procedure had given no error messages. The problem only became visible on checking it, when MSBACKUP repeatedly asked for the correct disk but wouldn't accept it. Of course, the first thing he asked me to do was re-run the test with different floppies. I had already done this, and it still failed. The call involved a repeated sequence of changing something in CONFIG.SYS, reboot, and try the test procedure again, which took about 4 minutes to execute. I was familiar enough with DOS to use the editor, reboot, and test MSBACKUP, so it only took about 10 seconds to tell me what to try next. I wasn't sure during this call whether the tech was also handling another call at the same time. I didn't hear any voices but the tech could have been using a mute button. After I finished the test procedure and said it still failed, he responded right away. He also went away for significant periods of time to look things up, which might have involved taking another call. I got the impression he was trying things at random, especially when he wanted to add things to the EMM386 command line, and I reminded him I had determined it failed even if I deleted that line. He wanted to try it anyway. Eventually he hit a combination that worked. I ended up with two extra parameters on EMM386 (IMHO, redundant but harmless) and two on HIMEM (which worked, but he couldn't explain what they did). Overall, I think I executed the test 20 times. The problem was fixed, finally. I hate to think how it would have gone if the problem only showed up half of the time, rather than consistently. I later determined that MSBACKUP was absolutely useless to me as it couldn't be made to restore a crashed and reformatted hard disk partition while running from floppy. It just says it should be run from the hard disk. I'm glad I kept the DOS 5.0 BACKUP and RESTORE around. Gordon L.

First, local electrical codes. Places like Rochester MN (home of the Mayo Clinic/Hospital) have tough codes. Don't want all those VIPs to go up in smoke. Second, lightning. Though I have not have much in the line of personal experence, I have had several 'old timers' tell me that proper grounding of the conduits, and trays/ladders helps reduce some bleed over EMP from lightning strikes near by. These guys work with 2 Ghs Mw, and had 300' towers to deal with, allong with 150 Mhz Radios/et all. Third, how long are you going to be in the building? Conduit eases the job of pulling new stuff through. Like replacing station wire with level three, and then when three becomes passe (accent on e) level five and Fiber. Foruth, physical plant. It is much less dificult to maintain a system that does not look like a mutant drunken spider lives above the suspended ceiling tiles. If one run dies, and you need to replace it, you wind up making a trip across several cubes, and disrupting many individuals. Conduit on the other hand is easy, if you are on the same level, generaly the tray/ladder is in the main hallway, and the conduits connect there. simply pull the new run through the tray/ladder to the conduit position, and run a fish tape up the pipe and pull. I don't recomend anyting less than 3/4" conduit. Fifth, EMI/RFI. Good conduit (metal not plastic) reduces the level of external noise. However, it does make the cross talk level go up. Given a choice between two evils, I will take cross talk, as trying to get the local radio station to not put out 100,000 watts is very hard, but I can always pull shielded runs for the very worst cross talking runs.

The company I am an agent for offers unlimited switched 800 usage (both in terms of different 800 numbers and usage of those numbers) for a single $5.00 monthly subscription fee and $.129/minute flat rate nationwide with NO MINIMUM USAGE requirements -- even cheaper for dedicated circuits. While I don't want to turn this into an ad, I felt that you might want to be alert to the fact that smaller carriers are getting EXTREMELY competitive with regards to 800 service. This is the next big wedge between the larger and smaller carriers; smaller carriers don't aribtrarily mark the 800's up and pass the savings along to the customers. I am an 'average' customer and have an 800 number ringing into my home. I don't necessarily use it a lot, but it's a lot cheaper and easier than a calling card and I'm not paying any extra monthly fees as I got my outbound on the bill as well, so why not? Of course, I'm contributing to the national shortage of 800's ...

As you know from our previous Cyber Liberties Alerts, Congress is moving to dramatically restrict the free speech and privacy rights of online users. On March 23, 1995, the Senate Commerce Committee approved the Exon/Gorton bill (the so-called "Communications Decency Act", also known as S.314) as an amendment to the Telecommunications Competition and Deregulation Act of 1995. While the proposed legislation was modified to include some defenses from criminal liability for online service providers, users are still very much at risk of both massive fines and imprisonment. The ACLU has written an open letter to online providers, copied below, that urges them to wage a full-scale fight for the rights of online users. Some providers are still actively standing up for your rights while others may not be. There are still opportunities to fight the legislation in both House and Senate, but the fight will not succeed without the concerted efforts of online users, civil libertarians, and online service providers. Remember that the Senate Commerce Committee approved the Exon/Gorton amendment despite opposition letters and petition signatures from over 100,000 online users. ACT NOW: Write to your online service providers and ask them to make a public declaration against the Exon/Gorton amendment and to push aggressively for the greatest amount of free speech and privacy for online users. (A sample letter is attached.) Please copy your letter to the following e-mail address: infoaclu@aclu.org. In addition, continue to voice your opposition to the Exon/Gorton Amendment to members of the Senate Commerce Committee and your own senators. See our previous ACLU Cyber Liberties Alerts for instructions on how to reach the Senate: gopher://aclu.org:6601. ------------------ [COPY] An Open Letter to Online Providers Regarding the Exon/Gorton Amendment March 28, 1995 On March 23, 1995, the Senate Commerce Committee voted to violate the civil liberties of every present and future member of the online community. The so-called "Communications Decency Act" was modified to include some defenses from criminal liability -- but these are available only to online service providers. In fact, other modifications made the legislation worse for users. The Exon/Gorton amendment remains a blatant violation of the free speech and privacy guarantees of the Constitution. We therefore urge all online providers to continue (or, if necessary, to begin) a full-scale fight for the rights of online users against the government interference embodied in the Exon/Gorton amendment. The Exon/Gorton amendment subjects online users to surveillance and imposes criminal penalties for messages deemed by some government official to be "indecent, lewd, lascivious or filthy" -- all communications protected by the First Amendment. By criminalizing the content of private messages, it would invite active interference in the basic speech of everyone using a telecommunications device. The amendment was attached to the Telecommunications Competitionand Deregulation Act of 1995, which was approved by the Commerce Committee and is being sent for consideration to the Senate floor. There are still opportunities to fight the legislation in both House and Senate, but the fight will not succeed without the concerted efforts of online users, civil libertarians, and online service providers. Sexual expression has been a fundamental part of human communication from the beginning of recorded history. The online community is no different. There is no question that talk about sex and the exchange of sexual images has contributed to the vibrant quality of online communications, and an increasing number of online subscribers. And Congress need not ban constitutionally protected forms of speech in order to protect children from sexually explicit materials. Interactive technologies allow users -- including concerned parents -- to have more control over content than any previous communications medium. Many of the traditional arguments for restricting sexually expressive material, such as radio/TV's assault on unwilling listeners or the fear that a child will wander into an adult bookstore, simply do not apply to interactive technologies. Moreover, the Exon/Gorton amendment's censorial sweep encompasses content that has nothing to do with sex -- anything deemed "indecent" or "filthy" -- subjective terms that could apply to any message outside the mainstream. The amendment would make the online community one of the most censored segments of communications media when logic dictates that it should be the least censored. The Exon/Gorton amendment also subjects an industry that has blossomed without government control to an unprecedented amount of interference and intrusion. We applaud those online providers who have both publicly declared their opposition to the Exon/Gorton amendment and who continue to fight for the constitutional rights of their subscribers. These providers recognize that no one in the online community will benefit from an amendment that seriously threatens the free flow of information and the diversity of content transmitted over online networks. To achieve the liberating potential of the information superhighway, Congress must ensure that interactive technologies enhance rather than stifle democratic values like user choice. We therefore call upon ALL online service providers to join online users and civil libertarians in the fight against the Exon/Gorton amendment. We urge online service providers to make a public declaration against the amendment and to push aggressively for the greatest amount of free speech and privacy for online users. American Civil Liberties Union "Eternal vigilance is the price of liberty" ---------------------- SAMPLE LETTER Dear [name of each of your online service providers]: I am writing, as a user of your service, to urge you to make a public declaration against the Exon/Gorton amendment to the Telecommunications Competition and Deregulation Act of 1995.

I urge you to: *Make a public declaration against the Exon proposal. *Aggressively lobby the Senate to vote against the Exon proposal, and aggressively lobby to prevent similar proposals in the House version of the telecommunications reform legislation. *Continue to push for the greatest amount of free speech and privacy for online users.

The problem is that when the other party is busy or keeps ringing, the voice message that comes up confuses my "high tech" Telebit Modem, and it will mess up everything holding on to the line for a long time and eventually will get messed up in its brains as well. So, I tried to contact AT&T in an attempt to turn the damn voice prompt off. In my opinion, they are breaking my phone service by doing this. The best resource in navigating AT&T seems to be the AT&T operator, so I dialed 00 and mentioned the problem and that I wanted to turn that service off. The operator said that they think it is a great service, however, the business office for residential customers should be able to take care of it. After talking to the business office it seemed they did not know that I had that service since it was not showing up in their system. Somebody figured out it was a different part of the corporate structure, and they gave me their phone number. So, I called there. The person I talked to tried to pursue me into keeping that service, but they could make the voice prompts go away by keeping them silent. Only if I punched #123 I would get the voice menu. I disagreed out of instinct and insisted that I wanted it turned off and that it was breaking my phone service. (Everything worked just fine without the voice prompts.) About the same days, I also asked the regular business office to turn on the accounting system since I wanted to keep track of my calls in how much they cost for which purposes. For that, I had to be forwarded to a zillion different places, and although I was promised that it would be turned on within ten business days, it was not. That matter took another call a month later to ask for the accounting to be activated again. This time it worked and they turned it on. In order to use the accounting codes, you have to dial a 0, the area code and number, and then a combination of numbers when you hear the AT&T bing tone.. Then the voice comes up again and says thank you, and I am surprized that none of these prompts is confusing the modem. It must be looking for the first ring or busy signal. (It needs to count four or five busy signals to decide.) The accounting codes were really working, but so were the True Messages prompts. So I called the True Messages Unit again, and they told me they have taken it out. I should talk to long distance repair. So I did. They told me it was my fault since I was dialing a 0 to start the call, and therefore activating what nonsubscribers are getting. They also wanted to know why I was dialing a 0. I explained the accounting codes. I was assured that they would be trying to exempt my number from that service, and it had to be done this way since there was no provision for not wanting the default service options. OK, I was assured another ten business days. Of course, nothing changed. Now this time, being peeved about the entire matter, I called Sprint, and got information on how much their service would cost. I have the TrueWorld calling plan with AT&T as well as AnyHour. They seem to have comparable plans, and the accounting service as well, although for a small fee. I also started to keep the names I talked to. When I called them at 1-800-336-0445 end of February, after being told by the rep that I had to call another number at AT&T I mentioned that I do not have to department hunt at AT&T and I am sick and tired of being forwarded around and given different numbers to call. I asked to talk to the supervisor, and got to talk to her. At first she wasn't sure what the problem was, but then she assured me that she would contact the necessary department and let me know about the result. This was the first time I was getting service as expected, since she called the next day, and she said that they can't turn it off. If I wanted to know why, I could call the supervisor at the other part of the company, and she gave me the number. So I called. He was very polite and said that they did not have the option in the computer, but he could put a form thru the process and it would work. That was March 1st. Nothing changed. March 29th, I called the same supervisor and reminded him of our conversation. I told him I was following up since nothing seemed to change and if they would follow up on the request form they filled out. He said they did, and they found out that they cannot turn it off. (this sounds familiar by now) - looks like they are struggling with this giant automata with enough CPU horsepower to match the worlds computers, and loosing control of it :-) He offered me to have someone from the corporate offices call me and talk about why they could not do it. I gave them my other phone number, and said that I would like to get in touch with this corporate person in a week, or I will switch to Sprint. (I am tired of the ten business days equals a month game.) I am just curious why this cannot be done. Could I complain to the FCC because they are breaking my phone service? Mustafa Soysal msoysal@mistik.express.net [TELECOM Digest Editor's Note: There is an annoying feature on some of the phones here although its not in every central office so far as I can tell, and mostly on pay phones. When you dial someone, after the third ring a recorded announcement comes on superimposed over the ring which says 'your party is not answering', and it goes on to tell how you can press certain keys to leave a message (at an additional charge of course). People have reported that to a modem it sounds like a voice -- which it is -- so the modem hangs up. PAT] ------------------------------ From: lincmad@netcom.com (Linc Madison) Subject: Phone Books no Longer Free Date: Fri, 31 Mar 1995 00:42:03 PST Well, as most of you know, on January 1st Pac*Bell restructured its rates to increase monthly service charges and decrease intra-LATA toll charges. At the same time, IXCs were allowed to carry intra-LATA traffic without sneaking quietly around the rules. A few other changes happened at the same time. Some years back, just after divestiture, you could get any Pacific Bell directory within your LATA just for the asking. A few years later, about 1988, I think, they started charging for yellow-pages-only volumes -- no charge for white pages or combined white-and-yellow. They now charge a "nominal" fee of "$10 to $38, depending on the size of the directory" for *all* directories you order, including within your own LATA. At the same time, one of the unpublicized aspects of the change in the rate structure is that the cost of ZUM (Zone) calls has been changed. Zone 1/2 calls are now $0.03/0.01 instead of 0.04/0.01, and Zone 3 calls are now 0.08/0.02 instead of 0.10/0.04. However, instead of 30% evening and 60% night discount, they now give 30% and 40% discounts for time of day. Thus, off-peak rates have increased almost 50% for local calls. You can still get unmeasured residential service, but the disparity in cost has widened with the new rate structure. (old: $4.45/8.35, new: $6.00/11.25) I also checked with Sprint on some of the changes they've made. They have been pushing their new $0.10/minute (7pm to 7am) $0.22/minute (weekdays) plan. They have also been pushing their new intra-LATA service. What they don't tell you is that if you do both, you actually pay HIGHER rates for the privilege of dialing an extra five digits (10333 at the front) than if you use Pac*Bell. Their rates for intra-LATA tolls are $0.14 weekdays and 0.10 night/weekend. Even in the last mileage band, Pacific Bell only charges $0.1470/0.1360 for daytime rates. So much for Sprint's claim to be "always" cheaper than Pac*Bell for intra-LATA calls. Of course, my interest in that angle of the question is mostly academic, since almost all of my non-local calls are interstate.

I bought mine second-hand in 1990 from an American via a BBS. In that same year I have been running a small voicemail BBS with about 50 users on it. People who know this card, know that it's possibilities are pretty limited. Some of the prompts are in English, and cannot be changed. Also the software which comes along with the card doesn't offer anything like a log file, so you can see who called. Besides this, the card itself is good enough, it's just the software which is very limited. I managed to write a programm which can show on screen who is online, when, which prompt is being played etc.. Also I managed to write a little prog which makes it possible to switch on/off things on remote via the voicemailcard. With a little immagination it's all possible. Perhaps the wheel has already been invented, and someone already wrote software for the card, or has a better version from the original software. I am still runing with Answer 2.12, perhaps there is a update? I heard the compagny who made the card does no longer exist.

Bryant) Subject: Telemarketers Ethics Statement Organization: NETCOM On-line Communication Services (408 261-4700 guest) Date: Fri, 31 Mar 1995 00:52:42 GMT Below is the Ethics Statement of the American Telemarketing Association (dated 2/94). Use it to your advantage. ETHICS STATEMENT AMERICAN TELEMARKETING ASSOCIATION DEFINITION Telemarketing is the planned, professional use of the telephone to advertise, market or provide service functions. Telemarketing may be the only method used by a company to advertise, market or provide services, or it may be integrated with other techniques such as direct mail, field sales, etc. Telemarketing programs can be "outbound" (seller initiates calls) or "inbound" (buyer initiate calls). PROFESSIONAL GUIDELINES 1. Telemarketing call recipients can expect that there is reason for the call and the call purpose will be accomplished efficiently, courteously, and professionally. 2. The names of both the company and the communicator who makes or receives calls will be clearly identified when every call begins. 3. The communicator will approach each call courteously, and never use abusive language or a rude manner. 4. The communicator will accommodate the business person or consumer's time constraints, and if necessary, schedule a future re-call. 5. All telemarketing offers to the business or consumer public will be legal, legitimate, and have recognized value. 6. Repeated calls with the same offer will not be made to the same prospect/customer. Exceptions are regularly scheduled fund raisers, and membership or renewal drives. 7. Except in cases of public safety, by previous agreement, or calls to current customers, the business or consumer public can expect a live communicator to introduce the call. The public's time has as much value as ours, the professionals in this industry. 8. All telemarketing equipment will be carefully monitored to ensure proper operation. Equipment use will be supervised to ensure professional application to telemarketing programs. 9. Telemarketing organizations will follow all federal and state telemarketing regulations. OPERATIONAL GUIDELINES Hours/Days of Operation: Outbound business calls should occur during normal business hours. Outbound consumer calls should only occur between 9:00 a.m. and 9:00 p.m. local time, unless further restricted by local or state laws. Exceptions require prior consumer agreement. Calls should not occur on major national holidays. For inbound calls, hours and days of operation should be clearly advertised when calls are invited through advertising, catalogs, direct mail, media presentations, or other sales methods, to avoid caller inconvenience. Telephone Service Levels: Outbound: Sufficient telephone service should be provided to avoid communicator contention for available lines. With auto- matic dialing equipment, sufficient communicators should be scheduled to ensure that every telemarketing call recipient will speak to a live person immediately. Inbound: The seller must provide sufficient incoming lines to accommodate anticipated call volumes. Personnel: Telemarketing managers should follow these standards, as a minimum, when selecting and training all telemarketing personnel. Selection: 1. Mastery of the targeted audience's language. 2. Speak clearly and be easily understood. 3. Understand the call subject matter and be able to respond to most probably questions. [sic] Training: 1. Knowledge and understanding of product, service or offer. 2. Professional message presentation. 3. Understand performance measurements. 4. Observe record-keeping procedures. 5. Demonstrate appropriate business etiquette and behavior. Quality Control: Telemarketing center managers should regularly monitor communicators' performance by listening to business calls being made or received while they are in progress. Monitoring of communicators' calls provides a means for employers to observe and evaluate employee performance and give objective feedback. Monitoring helps employees by identifying performance deficiencies so additional training can be received to improve skills and performance. This guideline also provides a means to protect consumers/ customers and the employer against possible unethical practices by individual communicators. It also protects the employer's rights to supervise and regulate the quality of work being performed in his/her behalf or in behalf of his/her clients. ------------------------------ Date: Mon, 27 Mar 1995 22:53:09 +0300 From: mutafp@cakabey.ege.edu.tr (Mutaf Pars) Subject: Information Wanted on RS-485 Hello, Do you know anything about the RS-485 standart of EIA (Electronic Industries Association) or EIA's internet address?

You'll have to hook me up with your supplier of free fax paper. Clearly you must get it for free or you'd understand what's at stake here. The reason unsolicited fax advertisements are illegal/unwanted is that it costs the typical recipient MONEY (fax paper is not free for most of us) to receive it. I am not typical, since I have a fax modem and I didn't even have to empty the wastebasket, but neither do I believe that I was the only one who got one of these. Add up the cost of all the fax paper wasted on their fax-spam and it becomes a non-trivial dollar amount. That is why it is illegal. That is why I object to it. As for the other things that bothered me last week, let me ask you, how would _you_ like it if you got a piece of e-mail in your mailbox saying that "we think you'd be interested in what we have to sell, so we've put you on our commercial mailing list." _Some_ of us pay for the mail we receive. So although the legal status is (currently) somewhat different, the moral principle involved is identical. I didn't mention the number of telemarketing calls I got last week primarily because it doesn't cost me anything, even having answered the phone, to hang up on them.

A woman calls real sly ... and says 'hi honey, I need to get the model and serial number of your fax machine for the inventory records ...' cause she knows most secretaries or whatever will just automatically go look at the machine and come back with that information. Then by the merest coincidence of course -- of course! -- the next day or even a few hours later another call comes in from someone wanting to speak with the 'purchasing department'. After putting them on hold a couple minutes I change my voice and come back on the line as 'Smith in purchasing, how can I help you?'. Would you believe 'the warehouse' accidentally got an overstock on the very kind of fax paper used by the machine in my office ... and 'the boss' told them to get rid of it by making sure everyone with that model of fax/copier got an extra order at the 'wholesale price', and how many do we want before the overstock runs out and we get left behind in our stupidity for not stocking up when we could get it so cheaply ... Whenever the Nice Young Man calls with that pitch I always take another box or two, since its 'on sale' to reduce the inventory in the warehouse after the stupid mistake 'the boss' made in ordering so much of it. Trouble is, the stupid boss seems to make that same mistake week after week. By the way, the sky here is blue.

From the point of view of the endpoint application there is no difference between the two. They both provide 56 kbit/s bandwidth with no restriction on the data carried in the bearer channel. Background: The only time this terminology (56 kbit/s clear versus 56 kbit/s restricted) comes up is when referring to 56 kbit/s data over 64 kbit/s ISDN B-channels. Both services use V.110 rate adaptation (stuff a 1 in the 8th bit) to transport 56 kbit/s data over a 64 kbit/s B-channel. A clear channel 64 kbit/s connection means that any combination of bits can be transported over the B-channel without restriction or modification. A restricted 64 kbit/s connection means that at least one bit out of every 15 must be set to a 1 (usually this is simplified to 1 bit in 8 and is called "ones density"). In such networks, provisions are usually made to enforce this limitation (e.g., when the network gets a string of 8 zeros it forces the 8th zero to a 1, thereby corrupting the data path). When running 56 kbit/s over B-channels, since the 8th bit is always set to a 1, then it does not matter whether the data traverses a restricted channel or an unrestricted channel. Main Issue: The main problem people run into with these services is in signaling to the network. Some of the older switches in the US require the user to request "64 kbit/s restricted rate adapted to 56 kbit/s" in the SETUP message to the switch while others require the user to request "64 kbit/s unrestricted rate adapted to 56 kbit/s". In NI-1 (and in Euro-ISDN), the requirement is to use the latter. There really is no difference in the service in terms of bandwidth, bits allowed over the channel, etc. It is just an artificial difference imposed by two switch vendors making a different choice as to how to request the service. Hopefully, all switches will migrate to the NI-1 encoding. Hascall H. ("Chip") Sharp Teleos Communications, Inc.

Sorry I wasn't specific. The digital standards I'd be interested in are the ones that are or will become prevalent in the US. You mention GSM, but our local carrier today only offers TDMA, and I hear CDMA may be used more widely in the future. From what I've heard so far (please correct me if I'm wrong), the prevalent digital cellular standards are: US: TDMA (today) CDMA (possibly in the future, replacing TDMA or coexisting) Europe/Asia: GSM What makes GSM the one I should be talking about? You indicate that it's prevalent in Europe and Asia, but what about the US? I'd prefer a standard that worked everywhere, of course. > GSM uses a challenge-response protocol, not an ID query/transmit sequence, > to authenticate the caller.

Someone could record the communication and possibly decode in the next few days with a lot of trouble, but that's pretty unlikely for most communications and they can't reuse the information for decoding new transmissions on the fly because of the challenge-response. > Some of your other questions were not relevant to GSM.

With Call Waiting, if your receive a call while already talking and you answer the second call, you are charged airtime for the call on hold as well as for the second call. I don't understand why you should be charged double airtime as you are still occupying only one voice channel. Even in the case of Three-Way Conference, your cellular phone does not use two radio frequencies to talk to the two other parties; the conference feature is implemented usually with a conference circuit in the telephone switch itself. Thus I still don't see the validity of charging "double airtime". If it makes a difference, both companies sell these features either as an add-on with a monthly fee or as part of a "rate-package". (In either case, they still charge "double airtime" for usage. Does your cellular provider charge "double airtime" when using Call Waiting and Three-Way Calling? What is your cellular provider and what geographic area does it serve? [TELECOM Digest Editor's Note: I don't think Ameritech here in the Chicago area charges double. It never did make any sense to me why they do that; you are just using one over-the-air channel. What you do with that should be your business. I wonder if there would be any market for someone to start a three-way conference calling service for cellular customers so they could get away from having the cellular switch perform that function at double the rates? You are not alone; there have been other reports here of the same thing.

Its time to set your clock! This is just a reminder to our USA readers that this weekend commemorates not only the 150th anniversary of the invention of the telegraph by Samuel Morse on April 1, 1845, but also our semi-annual clock setting. The rule remains the same this year as before: spring ahead and fall behind. This being spring -- much to the chagrin, I'm sure of our Australian and New Zealand readers who are now preparing to freeze their butts off for the next few months while we here in the northern hemisphere turn the tables on them and get to bask in the sunshine and on the beaches -- we set our clocks ahead one hour. Officially its at 2:00 a.m. Sunday morning when we commence Daylight Savings Time, but anytime you happen to think about it on Saturday you might want to call 202-653-1800 for a good time. If you prefer to pay for your good time, you can get the identical message from the Master Talking Clock at 900-410-TIME. We do this each year -- at least most of us do, the people in Indiana are different, and remain the same time all year around, as well as parts of Arizona I understand -- with the rationale that we won't mind an extra hour of darkness as we sleep in the morning, but will appreciate the extra hour of sunshine as we frolic in the after- noon and evening. Anyway, sometime in the next day or so, attend to your clocks. Speaking of the time, I've noticed that as this mailing list gets larger and larger, distribution takes longer and longer. When eecs.nwu.edu is really busy, I've noticed sendmail running for many hours at a time as this list is processed. It is not uncommon for me to look at the mailqueue and find three or four different issues of the Digest all in there getting processed, anytime I check it 24 hours per day. I am experimenting now with mailing the digest in multiple parts. Not one after the other, but simultaneously. That is, I broke the list in four parts, and start four sendmails with each getting about 25 percent of what one sendmail had gotten before. This should speed up delivery a little, especially if you were in the bottom half of the original list. I would be interested in knowing approximatly how long it takes the Digest to reach you, based on the dateline given at the top of each issue versus when it actually reaches your site (NOT when you get around to reading it.) Of course the four sendmails take time from each other, and the sysadmin here traps all my stuff and pipes it through a special script which applies 'nice' values to my outgoing mail; sort of like a stop-and-go traffic light which restrains me based on the needs of other users at the site at any given time. So the improve- ment is not all I would like it to be, but I can't think of anything better right now. Let me know the results if you see any. Just general round figures are good enough. Under the theory that sendmail goes through the entire list looking for everything to a given site, I sort the list alphabetically from the '@' to the right. That means @aardvark.wherever always gets delivery first and @zygot always comes last. But at least the daemon finds everyone at a given site in the same cluster, which I assume saves a little time. Occassionally with two or three issues of the Digest in the queue at the same time the daemons run past each other, each benefitting from the lookups done by the other and this causes some of you to get delivery out of sequence; that is, issue 184 arrives before 183, etc. I don't have any answer for that. Your suggestions are welcome on how delivery might be speeded up, bearing in mind I cannot rip off all the cpu's here; nwu is already extremely gracious and generous with me. ... Two special mailings will follow immediatly for your weekend reading. One deals with ISLIP 95 and how to participate; the other tells of the changes the Internet is undergoing at present as the networks involved undergo change and expansion. Have a a nice weekend!

Kimberlin <0004133373@mcimail.com> Subject: Local Competition Bill Passes NC Senate The March 31 reports state Senate passage of a telephone competition bill the preceding day, less than three weeks after passage of a bill in the NC House (parenthetical remarks are mine): Local Phone Rules Changes Clear Senate RALEIGH -- Telephone customers, accustomed to long distance companies battling for their business, soon may find themselves as popular with providers of local service. The state Senate passed a bill Thursday that would allow competition for 3.3 million local phone customers. The House, which approved a similar version (on March 10), is expected to OK the Senate's changes. "The bill sets the timing; sets the standards." said Senator David Hoyle (D-Gaston). "Most importantly, this bill protects the concept of universal service." Universal service is the guarantee (which first arose in 1913 as part of the settlement of a Federal antitrust suit against AT&T) that anyone in any community of the state who wanteed a telephone would be able to have one. The bill's language and every discussion leading up to its passage indicated that lawmakers would not accept competition and the accompanying drop in prices if it meant some communities would be left out. Lawmakers also put their trust in experts of the state Utilities Commission to work out technical and legal details. The bill is a close cousin of an original version written to the liking of the four companies affected DD Southern Bell, Carolina Telephone, Central Telephone and GTE South. The companies, which provide service to 90% of the state's telephones (the 20-odd smaller companies having less than 200,000 dial access lines each could maintain their monopolies so long as they do not engage competition outside their monopoly territories), like the bill because of changes in how the state will regulate them. The Utilities Commission now looks at how much it costs to provide local service and decides how high telephone company profits may be. Under the new bill, only the price of service is regulated. If companies can lower costs through increased efficiency or technological advances, they keep the amount saved. A spokesman for a coalition of long-distance and cable companies aiming to break into the market said the bill was a fair compromise. ... Notes for newcomers: The proposed start date for competitive operations in NC is July 1, 1996. There is already limited dial tone competition in the city centers of New York and Chicago, while about 20 states have some sort of competition legislation underway. Much of the activity at the state level has been spurred by an implied threat of Federal demonopolization. Worldwide, England and New Zealand have had local dial tone competition in operation for as much as five years in some areas. ------------------------------ Date: Fri, 31 Mar 1995 23:15:46 -0500 From: johnl@iecc.com (John Levine) Subject: Re: March 1995 NYNEX Bill Insert - PulseNet Service > Why is an RBOC's inclusion of a bill insert or it's use of it's > customer list for advertising worse than the ads included in the bills > of almost every company in America? Because the RBOC is a regulated utility with its rate of return set by the government. (You work for an RBOC, so I suppose you can be excused for swallowing the usual RBOC agitprop that says "we're just like any other business in the country unless we happen to be wearing our Sacred Public Trust hat.") In this case, the insert in the bill sent out to regulated customers advertises what appears to be an unregulated service. The mailing is paid for by regulated customers. It's yet another sneaky subsidy to the unregulated side of the business. > Does anybody really believe the hype that residential phone service > is this monstrous revenue generator that supports all the other > projects of the LECs?? Only people who read RBOC balance sheets and annual reports. (Well, not just residential, but certainly residential and business POTS.) Read your employer's financial statements. I do, I'm a stockholder. You've made a lot of money for me over the years, largely off the backs of your regulated ratepayers. > Does anybody really think that ATT et al want to get into the local > phone service business because there's so much money in it? Look at the overall return on the RBOCs vs. that of AT&T since 1984. > Does any one want to provide JUST telephone service? The IEC's only > interest in local service is as a means to avoid access charges to the > LECs. Could it be that they believe that they can provide a superior service at a competitive price? Naah. Oh, sorry, didn't see the Sacred Public Trust hat. In a lot of places such as California and New York, the RBOC is doing a really lousy job of providing phone service. People are willing to consider seriously getting local phone service from the cable company and outfits like MFS not because they're a lot cheaper (they're not) but because they can provide the service that customers need in a timely and reliable manner, and the RBOCs don't. SBC (SWB's holding company) is to be commended for sticking closer to its telephonic knitting than have the other RBOCs such as NYNEX, USWest, and PacTel, and seems still to provide quality service in most places. But even SWB does its share of inane and predatory things. Try pricing an ISDN line in Texas, for example.

This question is probably relative to cellular service. At this point, cell carriers owned by the RBOCs (and probably GTE) have to provide equal access. Other cell carriers don't. This means, for example, that when I got my NYNEX Cellular car phone, one of the things that NYNEX asked was which long distance carrier I wanted. (The salesman was astonished when I said Allnet rather than AT&T. But for 13.5 cents/min flat, billed with my wireline and 800 calls, it's not a bad deal.) Had I signed up with Cell One, I'd also have had that choice, because the Cell One in Boston happens to be owned by SBC, one of the other RBOCs. I believe that McCaw is also going to equal access as a condition of the merger with AT&T. Non RBOC carriers don't offer equal access and route all toll calls to a preferred carrier, no doubt at a big markup. There is a schedule for all cellular carriers to go to equal access, just as there is a schedule for non-RBOC wireline carriers to go to equal access. In both cases, there's quite a lot of resistance, both because of the extra equipment required to implement equal access, and because it'll end some of the sweetheart sole source deals they have now. Incidentally, NYNEX Cellular's implementation of equal access is terrific. I called their customer service line to switch carriers, and the next call I made two minutes later went to the new carrier!

Actually, the justification for the original law was never the paper. The paper cost is not that burdensome. The real problem is the time the machine is tied up receiving junk faxes, when it could be doing productive business for the owner. A lot of junk traffic can tie up a fax machine enough that legitimate faxes can't get through (consider the retry intervals and the time spent ringing and connecting, and you can see that a fax machine doesn't have to be operating continuously to be effectively saturated). This is the argument originally used in the legislative process.

I answered: > Only people who read RBOC balance sheets and annual reports. (Well, > not just residential, but certainly residential and business POTS.) > Read your employer's financial statements. ... According to the 1994 annual report, SBC's total revenue in 1994 was $11.4 billion, making it one of the smaller RBOCs but still an enormous company. The breakdown was: Wireline service $4.0G* Cell service $1.7G Interstate access $1.9G* Intrastate access $0.9G* Toll service $0.9G* Yellow pages $0.9G Everything else $1.1G "Access" is both the $3 FCC line charge and the per-minute charges that long distance carriers pay the LEC for both incoming and outgoing calls. So if we look at the monopoly parts of the business (the starred entries), that's $7.7G. Communication related semi-monopoly revenue (cellular and yellow pages) add another $2.6G. Everything else is just $1.1G. Is regulated service a cash cow? Moo. Some may argue that intra-LATA toll service isn't a monopoly, since most states allow competition. But SBC's intra-lata toll minutes have continued to rise every year since divestiture except 1990, so if there's competition, there ain't much. Toll revenue dropped 6% this year, but the notes say that's partly because they added extended area dial plans which turn toll revenue into local service revenue. Finally, returning to the original point, I tried to find the split between residential and business revenue at SBC. All I could find in the 10-K is a note that they have roughly nine million residential lines and four million business lines in service. Business lines generate a lot more revenue than residential, so let's make the extreme assumption that a business line generates 10 times the revenue that a residence line does. Even in that case, residence revenue would be 18% of the total, or $1.4G, still considerably more than all non-phone revenue combined. In a word: moo.

Send out flyers telling unmeasured customers how much they would save switching. 3. Wait 'till most of the customers switch. Repeat 1 and 2 as needed. 4. When the percentage is low enough, yank the carpet out from under the stragglers (bribes to PUC may be in order if they are not already either lap-dogs or on the payroll). 5.

It seems that wth slightly more than 365 days per 'year', i.e. 365 days, 5 hours, 48 minutes and 46 seconds, the common rule of 365 and one-fourth days per year -- that is, add a day every four years -- does not work out quite right either. So although we usually add a day every four years, once every hundred years we *skip* the extra leap day to make it balance out. But that also leaves things a little out of whack, so once every four hundred years we *do not skip* the extra day. Normally we skip the extra day in years that end in double zero; but an exception is in years that end in double zero but are also divisible by 400. Therefore, to keep our calendars somewhat in synch with what's really going on in the universe, the years 1700, 1800, and 1900 were not leap years; but the year 2000 *will be* a leap year. By observing this rule of an extra day every four years except skipping one leap day every hundred years except adding one leap day every four hundred years our calendar will pretty much stay in synch until sometime in the 33rd century -- about 1300 years from now -- when another general adjustment will be needed. I have not yet decided if I will publish an issue of this Digest on that day or not. For that matter, I'm not sure if in 3200 it will be necessary to add a day or subtract a day from the calendar, but anyway, around that time we will have gotten nearly a full day out of alignment again.

The university had just implemented an agreement that routed all 0+ calls from university phones via AT&T. If Southern Bell had a carrier code, I could dial 9 (to get out) + 10 + code, but alas, they do not have a carrier code. Since Southern Bell has much lower rates than any LD carrier within the "Triangle J" calling region, the effect was to increase the price of calling-card calls from Raleigh to Durham and Chapel Hill by ~ 200%-400% depending on the time and duration of the call. At the time, PAT responded that the university was probably within their rights doing this to office phones, but it might be illegal to prevent dorm residents from using Southern Bell cards. I am meeting tomorrow with the university's Telecommunications people to discuss this situation. Does anyone have further information? Specifically, can someone tell me -- 1. Is it permissible for the university to prevent people from making Southern Bell calling-card calls from their offices? 2. Same question, from dorm rooms. 3. What are the chances that the university's switch could be programmed to define an alternate prefix for reaching Southern Bell? E.g., 7 + NPA + number instead of 9 + 0 + NPA + number. Thanks for your help, Ed [TELECOM Digest Editor's Note: A short answer would be it is NOT illegal for the person (organization) which pays the phone bill to decide how the calls will be handled. The university is within its rights to decide how to administer their phone system where *employees* are concerned, or *students using administrative phones*. There are different rules where students as *residents* are concerned. You had better stick to a discussion of *students as residents* and their rights ... you'll lose otherwise!

Kimberlin <0004133373@mcimail.com> Subject: When Handed a Lemon, Make Lemonade! Apropos of the recurring posts here on the matter of problems from being assigned a telephone number similar to that of one that takes many incoming calls, today's column by Art Buchwald is just too funny to not post in its entirety. I do not know if the story or persons are real, nor would I recommend anyone actually do what the story indicates. Rather. enjoy! Phone Won't Stop Ringing? Here's What You Do By Art Buchwald Leola Starling of Ribrock, Tenn., had a serious telephone problem. But unlike most people she did something about it. The brand-new $10 million Ribrock Plaza Motel opened nearby and had acquired almost the same telephone number as Leola. From the moment the motel opened, Leola was besieged by calls not for her. Since she had the same phone number for years, she felt that she had a case to persuade the motel management to change its number. Naturally, the management refused claiming that it could not change its stationery. The phone company was not helpful, either. A number was a number, and just because a customer was getting someone else's calls 24 hours a day didn't make it responsible. After her pleas fell on deaf ears, Leola decided to take matters into her own hands. At 9 o'clock the phone rang. Someone from Memphis was calling the motel and asked for a room for the following Tuesday. Leoloa said, "No problem. How many nights?" A few hours later Dallas checked in. A secretary wanted a suite with two bedrooms for a week. Emboldened, Leola said the Presidential Suite on the 10th floor was available for $600 a night. The secretary said that she would take it and asked if the hotel wanted a deposit. "No, that won't be necessary," Leola said. "We trust you." The next day was a busy one for Leola. In the morning, she booked an electric appliance manufacturers' convention for Memorial Day weekend, a college prom and a reunion of the 82nd Airborne veterans from World War II. She turned on her answering machine during lunchtime so that she could watch the O.J. Simpson trial, but her biggest challenge came in the afternoon when a mother called to book the ballroom for her daughter's wedding in June. Leola assured the woman that it would be no problem and asked if she would be providing the flowers or did she want the hotel to take care of it. The mother said that she would prefer the hotel to handle the floral arrangements. Then the question of valet parking came up. Once again Leola was helpful. "There's no charge for valet parking, but we always recommend that the client tips the drivers." Within a few months, the Ribrock Plaza Motel was a disaster area. People kept showing up for wedddings, bar mitzvahs and Sweet Sixteen parties and were all told there were no such events. Leola had her final revenge when she read in the local paper that the motel might go bankrupt. Her phone rang, and an executive from Marriott said, "We're prepared to offer you $200,000 for the motel." Leola replied. "We'll take it, but only if you change the telephone number." [TELECOM Digest Editor's Note: Very funny, but the fact of the matter is Leola is committing fraud by representing herself as an employee of the motel; I hope they sue her big time. How would you like it if your bar matzvah or wedding got screwed up on account of that old witch?

AC ??? overlaid on AC 817 (Ft. Worth metro area) 21) ??/??/?? AC 340 splits from AC 809 (Puerto Rico) Notes... 1) Originally reserved for Wireless services (cellular phones and pagers). All wireless services in 708 would have been forced to move to 630. All new wireless services in areas served by 312 and 708 would have been in 630. Wireless companies appealed to the Illinois Commerce Commission and to the FCC. The FCC seemed to indicate that wireless overlay areacodes were discriminatory. The latest plan is for 708 to do a three-way split: The south/southwestern suburbs will retain 708, the western suburbs will get 630 and the northern suburbs will get ???. No date for the three-way switch has been announced. Any wireless numbers assigned to 630 in the meantime would be reassigned into the geographical codes. 2) 334 for Southern Alabama, Northern Alabama keeps 205 334 will contain Auburn, Dothan, Mobile, Montgomery and Selma 205 will retain Anniston, Birmingham, Decatur, Huntsville and Tuscaloosa Permissive period ends 5/13/95 3) 360 will cover all of Western Washington except Seattle and immediate suburbs which stay in 206 360 will contain Bellingham, Bremerton, Olympia, Vancouver 206 will retain Auburn, Bellevue, Everett, Redmond, Seattle, Tacoma Permissive period ends 5/21/95 4) First numbers assigned in AC 281 (until 2/29/96) will be wireless services. After 3/1/96, all new numbers assigned will be in 281. Mandatory 10 digit dialing for all local calls in the 713/281 area begins on 3/1/96. 5) 954 was originally to be a wireless overlay on top of 305 effective 3/1/95. The Florida Public Service Commission rejected this proposal and decreed that Broward Co. (Fort Lauderdale) would move to 954 and Dade Co. (Miami) would retain 305. Effective when? Southern Bell is appealing the decision since 305 would have to split again in a few years. 6) 520 will cover the entire state of Arizona except Phoenix and its suburbs which stay in 602 520 will contain Flagstaff, Prescott, Sierra Vista, Tucson, Yuma 602 will retain Buckeye, Chandler, Glendale, Mesa, Phoenix, Scottsdale, Tempe Permissive period ends 7/23/95 7) 970 will serve Northern Colorado and the Western Slope except Denver and its suburbs which stay in 303 970 will contain Aspen, Durango, Fort Collins, Grand Junction, Greely, Loveland, Steamboat Springs, Vail 303 will retain Arvada, Aurora, Boulder, Denver, Englewood, Littleton, Longmont Permissive period ends 10/1/95 8) Southwestern coast of Florida splits: Southern part moves to 941; Northern part (Tampa-St. Petersburg) stays in 813 941 will contain Bradenton, Fort Meyers, Lakeland, Sarasota, Winter Haven 813 will retain Clearwater, St. Petersburg, Tampa Permissive period ends 3/3/96 9) 540 will cover all of Western Virginia except the Washington DC area which stay in 703 540 will contain Blacksburg, Roanoke, Salem, Winchester 703 will retain Alexandria, Arlington, Fairfax, Falls Church, Mclean Permissive period ends 7/13/96 10) SW CT (Fairfield and New Haven Counties) will retain 203; the rest of the state will move to 860. 860 will contain Hartford, Norwich and New London 203 will retain Stamford, Bridgeport, New Haven, Danbury, Waterbury Permissive period ends 10/6/96 11) First numbers assigned in AC 562 will be wireless services in the area served by AC 310. Landline services in AC 310 and wireless and possibly landline services in AC 213 and 818 will follow. Wireless companies and MCI are appealing to the FCC, especially given the decision in the Chicago case. 12) Eastern Tennessee moves to 423 while Middle Tennessee retains 615 423 will contain Chattanooga, Clarksville, Johnson City, Kingsport, Knoxville 615 will retain Murfreesboro, Nashville Permissive period ends 2/26/96 13) Permissive period ends 9/30/96 14) Northwestern South Carolina moves to 864, rest of state keeps 803. 864 will contain Anderson, Greenville, Rock Hill, Spartanburg 803 will retain Charleston, Columbia, Florence, Myrtle Beach Permissive period ends 5/1/96 15) AC 770 will either be an overlay on AC 404 or a geographical split 16) Mandatory 10 digit dialing for all local calls in 214/972 area begins on 8/1/96. All new numbers assigned after 2/1/96 will be in 972. 17) 888 will be used as an extension of 800 "Free Phone" services. 18) No further details 19) No further details 20) Overlay similar to Dallas 21) Unconfirmed.

(1-800-827-6364) Reply-To: andrewm486@aol.com (AndrewM486) This is a recurring problem for all LD carriers. When an institution makes a deal with one carrier, all others are blocked. Is it legal? Apparently the logic is as follows: As the institution owns the facility and it doesn't present itself as an open access provider, it can chose whoever it wants to provide whatever services it feels appropriate. The logic continues ... if a hospital chose to use a particular laundry, and you wanted to use another, should they have to accomodate your request and work with other laundries as well? Whether you 'buy' the logic is irrelevant; this has been challenenged in court on a number of occassions, and upheld. What is NOT upheld, hoever, is a coin phone being blocked. Almost every carrier has an 800 access number ina addition to its 10XXX number. You might want to ask BellSouth if they have one, and if they don't why don't they get one? The costs are almost identical (if not lower) than the standard access costs. Good luck! Andrew Mark [TELECOM Digest Editor's Note: You are correct. A company can do whatever it pleases with its own PBX/Centrex service. It pays the bills and can choose the carriers and services it desires. But if there are payphones on the premises -- for example, in the company lunchroom -- those have to be unblocked. The exception in the case of payphones are those which are *semi-public* ... that is, someone is paying telco to have them there. In that case, those can be handled as the 'subscriber' sees fit also. Telco only puts in commissionable (truly public) payphones where they can see a profit (or at least not a loss) for themselves. But anyone can have a payphone; if you choose that kind of service and pay the monthly fee required, then legally it is called 'semi-public' meaning a small subset of the public is likely to use it on a pay-as-you-call basis. So before you bang your company or university or whatever for 'pay phones' that you deem not in compliance, make sure you find out if telco put them there and pays a commission for their presence or if your employer put them there to encourage employees to stay off the business phones with personal calls and is paying telco to keep them there. If your employer's money gets involved at all, then he gets to call the shots.

Personally I think the NFIB is a right-wing pressure group representing employers (mostly not sole proprietors) of privately-held businesses who begrudge every penny of salary, benefits, and business expense that they could possibly attribute to "government intervention", and long for a return to the antebellum days when employees could be bought and sold. Or, in the north, the sweatshop days when it was fine to dump your effluvium into the river or curb. The foundation of the bottom of the economy, perhaps. But that's a digression. Even if the NFIB were the Mother Teresa of business groups, it would be a waste of time to count "businesses" as a unit as if they were all equivalent. > Secondarily, if you want to talk about retail stores, I further suggest that > you consider this more carefully.

Date: Mon, 3 Apr 95 13:29:48 -0400 Organization: MIT Lincoln Laboratory About ten years ago I moved to Reston Virginia, and was assigned a telephone number that used to belong to the computer consulting company James Martin Associates. There were usually only a handful of calls a day, but they were often in the middle of the night, since many of the clients were overseas and seemed to have no concept of time zones. At first, JM's associates weren't very helpful, and the phone company was even less helpful (they offered to change our phone number for a fee). So my wife and I just started telling the callers they had the wrong number, and hanging up. After a couple of weeks, we called JMA and told them how many of their valued customers we hung up on. They decided to send out a mailing with their new phone number to all their current and former customers, and the calls slowed to almost nothing within a week. No fraud. No threats. You just have to make the company understand that it's in their own best interest for customers to have the right phone number.

How would you like it if your bar > matzvah or wedding got screwed up on account of that old witch? PAT] Most individuals make lousy targets for big corporations to sue: we have no money. How would you like it if such stuff was destroying your family life? We had a nice quiet number in a Dallas suburb until an after-midnight TV-advertising outfit, one of those "quick weight loss" schemes, got one "next door". We would get five to ten calls between midnight and 3 a.m. most nights. Phone company policy is, of course, "You're SOL (because we get lots of money from this company, and we don't care if you have a life or not)." I got as far as "the President's secretary" after Residential Customer Service could offer no help (who knows who "the President's secretary" really was, probably the janitor:-). I decided I was willing to accept late-night calls from strangers and discuss weight loss strategies and products. I told some people we might be moving out of the area (we were) or that I was new in the business (very), or might be soon out of it, or that maybe that for *that* person, I had no product to offer (indeed!), pried into personal information, mostly offered advice, but did not represent myself as part of the company they were trying to reach. After about a week, I got pretty good, and was probably providing a better service (cheaper, too) than the competition:-) Unfortunately, it showed no potential for profit, as people proved unwilling to pay for "Quit eating so damn much, and get some exercise", or variations on and expansions of same, especially after they had heard it. Perhaps it was my delivery, with growing irritability (from lack of sleep, and from multiple daily exchanges with SWBT) showing through. A surprising number of people who called were actually *eating during the call*:>) I learned to ask after hearing some munching noises once. After that got boring, we just unplugged the phone at bedtime. Either they quit advertising or, more likely, went OOB, in a few months. *Still* makes me mad at SWiBiT when I recall it. [TELECOM Digest Editor's Note: As unfortunate as these circumstances are, the fault lies with the person who misdialed the number. It is not the fault of the company advertising and it is not the fault of the telco. How many times should the company be expected to change their number to avoid the possibility that some one or more customers *too dumb to know any better* are not going to dial your number or my number in error?* How much is telco expected to do to prevent this? Mike Royko, the {Chicago Tribune} columnist seems to feel that AT&T should change *their* customer service number so that he won't get wrong numbers from idiots who don't know enough to dial 1-800 first. Of course, he is an idiot also -- one of the crudest and rudest in the business of writing a column in the papers -- so it is fun at times watching the idiots turn on each other. But why do you feel telco or the other (business) subscriber is at fault? Is it okay if they go to the trouble of changing their number so that some other private citizen gets harassed with wrong numbers instead of you? Now if they are continuing to put out advertising or directories with the WRONG number (your number!) printed in them, that is another matter entirely, i.e. the lady in (was it?) Washington State who was getting calls for the Probation Office because *they* would not correct an error in their printed material; also the airline schedule booklet with the misprinted number, etc. I had a case quite a few years ago where a real estate company in Chicago had my phone number listed in something they gave tenants for how to reach the maintainence man and janitor for their apartment building. But it was my number, not just something that *looked close to my number*. Then I think you have a legitimate complaint with the company involved, but if it is just a case of the public misdialing your number, your complaint is with the public. Businesses pull this on each other also; they take advantage of name and number similarities to get each other's customers. A good example several years ago here in Chicago was when the Hyatt Regency Hotel opened. For forty years prior there had been a 'Hotel Regency' in the downtown area; a real slum place that mostly served as a house of prostitution and overnight lodging place for Skid Row derelicts ... and it looked exactly that way. They took advantage of the fact that 'hotel' appears alphabetically ahead of 'hyatt' in the phone book. Even though the dump was listed as Hotel Regency and as Regency Hotel in the white pages, they did something else very clever: they added a listing they knew would come at the start saying 'Hotel Regency Reservations Office' (which they certainly were entitled to do legally) and wouldn't you know it, time and time again when people out of the area called Directory Assistance to get the number for the Hyatt Regency, the directory assistance operator, trying to be helpful, would say 'do you want the number for the reservations office?' ... and of course that is exactly what the caller wanted, and they would get SUperior-7-4900, which was the flophouse hotel instead. Well, so Mr. Smith, business executive in San Fransisco would call to get reservations 'at the Regency in Chicago', and the flophouse would take his credit card number and reserve a room for him. 'How do I get there coming from the airport?' he would ask, and they would tell him forthrightly and honestly that they were at 19 East Ohio Street, which indeed is the address of the flophouse. They did not lie, they did not misrepresent any- thing. Their attitude was we run a hotel also, albiet perhaps not in the style to which Mr. Smith is accustomed. They'd put through the charge on his credit card *and save him a room*. They knew the law very well, and that they had to have an actual room in his name. So Smith shows up at Ohare Airport, jumps in a cab and says to the cab driver 'take me to the Hyatt Regency in Chicago'. Off they go and needless to say the Hyatt Regency had no reservation for Smith. If he got in the cab and said 'take me to 19 East Ohio Street in Chicago' then the cab driver would take him there instead, and Smith would see for the first time that something seemed rather remiss. If he wound up first at the Hyatt Regency without the reservation he was counting on, his first reaction was to blame the hotel, but then he would get out his notes, check the address and phone number, and find out the truth. Or he might just be angry at 'how the hotel screwed up his reservation' and stay there anyway, producing his credit card to make still another payment for his room. Meanwhile the 'Hotel Regency' treated it as a no-show on a reserved room and legally pocketed the earlier payment. Some nights they had ten or twelve guests with reservations who 'failed to show up' and forfeited their advance payment. ... Time and again the 'guests' demanded their money back from the Hotel Regency but were refused, and the credit card companies held that there had been no fraud or misrepresentation, thus no refund, and of course many of the 'guests' had sent checks in the mail which had long since been cashed. One large corporation was severely embarrased when they reserved a week's worth of rooms for employees at a seminar and the The Hotel Regency gladly accepted their check for ten thousand dollars as 'deposit for the reservations'. They didn't get their money back either and in fact the flop house happily set aside a couple dozen rooms for a week. The Hotel Regency people would always sit there with a very straight face and claim that in good faith they had made the requested reservations. If you don't like our accomodations then leave and find somewhere else to stay. You didn't ask us if we were the *Hyatt* Regency; if you had we would have told you no. The Hotel Regency was sued by the Hyatt Regency to force them to stop taking reservations in that way -- for that matter they sued to make the flop house change its name to something other than 'Regency' and they lost that case when it was pointed out that the flop house was a corporation using the d/b/a 'Regency' and that the Hyatt Regency had never bothered to check first before taking that name for themselves when they opened in Chicago; the flop house actually had that word registered with the State of Illinois long before the Hyatt people came to town. Finally Hyatt settled with the flop house by buying them off; for a good sum of money the Hotel Regency agreed to change its name (it has been the Hotel Tokyo and/or the Tokyo Hotel since about 1977); to remove any and all listings in the telephone book which referred to 'Regency' -- although they were allowed to keep their same phone number -- and for a period of one year they agreed to respond to anyone on the phone who used the word 'reservation' in the phone call by making the statement "The telephone number for the Hyatt Regency Hotel and its reservations office is xxx-xxxx" then terminating the call immediatly after repeating the above statement if the caller asked to have the number repeated. They agreed to examine and read all mail which came addressed to 'Regency' (or some variation) at the 19 East Ohio address and forward mail which dealt with reservations 'or obviously' the Hyatt Regency to the 'real' hotel by that name on Michigan Avenue. Curiously, the two institutions are only a matter of about three blocks apart from each other which added to the confusion in the first place. Once 'Hyatt' had paid the requested sum of money to 'Hotel', the flop house immediatly filed all the necessary papers, changed their phone listing, during the interim answered their switchboard with 'Superior seven, four nine hundred' and had their janitor each day take over the reservations mail received the day before. Its still there at the same address and phone number; still a flop house catering mostly to semi-homeless people; but a sign on the front desk warns that 'you may not take visitors to your room' and that prostitution is not allowed on the premises. In the old days, the 'Hotel Regency' rented rooms by the day or *by the hour*; now they only rent by the week or the month however 'Illinois Public Aid rent vouchers are accepted here.'

In the first place, "SS7 programming" is a non-entity. SS7 is a mnemonic for "Common Channel Signaling System #7", a set of strictly defined protocols for inter-office signalling in the PSTN (Public Switched Telephone Network). As such, the end user has little or no access to the phones from, or using, SS7. This is language that the switches use to talk to each other. For CPE (Customer Premises Equipment) control, you're limited to ISDN (which is built on, and requires, an SS7 network to operate) or perhaps some sort of proprietary protocol that I am unaware of. There are several good references on the SS7 network, and I can dig them up is you are still interested, but I don't think that is what you are looking for. David M.

We do however have relationships with several of the major providers to provide them with capacity not only for their backbone, but as access lines for their customers. WilTel frame relay customers can also choose from several Internet providers which are also connected to our Frame Relay cloud. For larger capacity, we can also get you connected to a couple different service providers via our nationwide ATM network as was demonstrated at the last Atlanta Interop. If anyone has any questions about these access options, please feel free to drop me a line personally, or email info@wiltel.com.

Mike, Might I suggest Frame Relay? Most IXCs offering Frame Relay here in the U.S. now have nodes in Europe (Yes, including my little company-- WilTel) I think the costs should be considerably less than dedicated circuits, it is easier to add additional sites, and you have some degree of resiliancy since most networks will reroute your connections should their be any kind of trunk failures.

I also work for an RBOC. I still must point out that saying an RBOC is a regulated utility is not an answer to the question that was asked. You would have the readers believe that a regulated monopoly should not use it's customer lists to determine who to advertise to? Pardon my language but this is hogwash! It is an ultimate strawman argument. Would you prevent every cellular company in the US from using it's customer lists because they are also regulated by the FCC and there is not free and full entry into the cellular market by any competitor? > In this case, the insert in the bill sent out to regulated customers > advertises what appears to be an unregulated service.

I'm sorry, John, but this is nothing more than an assertion on your part that you expect the readers to believe. The statement "off the backs of" plays well as an emotional appeal against the "big, bad monopoly" but you still provide no concrete evidence to justify such a statement. Just where in the RBOC balance sheets and annual reports does it show that the regulated side of the business is illegally subsidizing the unregulated pieces of the business? I'm sure the FCC and local Public Utility Commissions would be very interested in such easily obtainable evidence showing we are playing fast and loose with the rules. Can you really show where none of the costs of the mailing were paid for by the non-regulated offering and ALL costs were paid by the regulated side of the business? Please note that there is absolutely NOTHING wrong with the profits from the regulated side of the business supporting the company as a whole as long as those profits do not surpass PUC mandated rates of returns or as long as the prices charged do not surpass maximum price levels depending upon the type of regulation imposed. Your argument is based on a basic misunderstanding that the "phone" company should be non-profit organization. If this were so there would never be any money to grow the business, to upgrade it, or to meet growing demand. By the way, do you really know what part of the business has the highest margin today and is the major target of competition? This is common knowledge and I will be giving away no secrets in confirming or denying it.

PAT] I think the argument is that you're using valuable -cellular switch- time and trunks rather than airtime ... which sounds like a preeeety thin argument to me. Most of the RochTel/NYNEX/Advantage conglomerate's service area is fairly low-density usage; the only times I have problems getting a channel are when there's a disaster on the highway at rush hour, and traffic is backed up and stopped all over the place. If there's plenty of air channels, wouldn't one hope there'd be no shortage of switch trunks? :) We had one such disaster here in Rochester last Friday. A tanker truck carrying 7500 gallons of gasoline crashed and exploded on the highway, right near the busiest interchange in the city. Fuel leaked into the sewers, and started burning and exploding underground. The highway was completely closed from 10:30 AM until well past midnight, and local roads that crossed the highway nearby were closed as well. It must have been a choke point, because traffic all over the south end of town was the worst I've ever seen. Oddly enough, even while in the middle of a traffic jam in the busiest shopping area of Rochester at 5:30 PM on a Friday night, I had no problem getting a cellular channel. I wonder if all the cellular "try a call on us for free!" booths in the nearby mall had a hand in this -- it'd look bad if your interested customers got reorders, and the signal meter is always pegged at the mall. :) Rob Levandowski Computer Interest Floor associate / University of Rochester macwhiz@cif.rochester.edu ------------------------------ From: rlvd_cif@uhura.cc.rochester.edu (Robert Levandowski) Subject: Re: Cellular Callback Information Wanted Organization: University of Rochester - Rochester, New York Date: Mon, 3 Apr 95 19:04:39 GMT In TELECOM Digest Editor noted in response to Engel2@ix.netcom.com (Bill Engel): > [TELECOM Digest Editor's Note: I cannot honestly see how this would work > since most cellular companies charge for all air time in or out don't > they?

PAT Some cellular carriers will let you reverse the airtime charges on incoming calls, so that the people who call you get the airtime charges. I don't know if they bother to inform the caller that the "local number" they dialed will end up costing them more than most long-distance calls ... At least around here, cell phones are subject to Equal Access. My phone is on Frontier Intl. long distance, with their discount plan which is billed seperately. When I called Frontier to ask if this was possible, they had to look it up ... the rep. said that apparently few people ever ask if they can add cell phones to discount plans, but that it's easily done and that it makes a great deal of sense to cut the costs of the cellphone as much as possible :) It makes me happy, because that's up to another 20% off my cellular LD over Frontier's normal rates.

PAT Well, I don't use a callback service with my cellular phone, but I do use my long distance carrier's 1-800 card service for any calls that I think will be over two minutes. To my knowledge selecting a long distance carrier is not an option with Cantel in Canada. I must use Cantel's long distance service, which is 15% *more* than "the standard rate set by the local phone company". Even the $0.75 to use the calling card is offset if the call goes over a few minutes.

Alex, I bought the developers software for the Complete PC several years ago from Digital Developement, 322 S. Patterson Blvd, Dayton Ohio, 45402, phone 513-223-0712. I don't know if they are still in business or not. At that time it cost $500.00 but it also included another procam board. I found that there is a one byte difference in the ROM that comes with the developer kit vs the one that was supplied by the CPC and the 2.12 voice mail. It did not come with the source code for 2.12 so any applications you wanted to do you had to write. It does come with a message editor to make your own prompts or messages. I wrote a program that would give out the daily Michigan lotto numbers via prompts. You could put in any drawing date and hear the numbers for that date up to a year ago. Now I am involved in doing Caller ID so I set the board up to answer the phone after the second ring. It will then play back the name and number received from the Caller ID hardware. It's been a good piece of hardware and I have two boards. One did die while CPC was still in business but they would not sell me just the suspected bad IC. I would have to send the whole board in for repair. I found a place that sent me a few samples of the part, replaced it and have two working boards again.

I think the 'flaw' in your reasoning is the fact that the 'directory number' "1-800-FLOWERS" is the property of the provider, not the customer. If 'Joes Flowers and Stormdoor Company' comes along and offers the 800 provider $ 10M/year for the number, there's no law that says that the provider can't 'pull' the number and re-assign it to Joe. (Might make an interesting court case). Much the same is being fought in the courts today over a couple of internet Domain Names (MTV.COM for example). Trademarking "1-800-FLOWERS" won't prevent this from happening, but it'll sure prevent 'Joe' from advertising it. John Rice K9IJ rice@ttd.teradyne.com [TELECOM Digest Editor's Note: I know what you are saying is true where local numbers are concerned; the subscriber has no property rights in the number assigned. That is part of the tariff. 'The Company' has the right to re-assign numbers as it deems necessary or desirable in the conduct of its business. But with 800 numbers is that true? It certainly was true in the days before portability when your 800 number depended entirely on the carrier you chose to use. I checked with someone just now at AT&T on this and got the following answer: "Portability means the number can be transferred from one carrier to another as the customer desires. In any event, the customer does not *own* the number; it remains the property of the serving carrier. AT&T may have 'owned' the number in the past, and now MCI (because of the customer's choice) 'owns' the number, but in any event the customer *never did own the number, and still does not own it*. Customers do not have property rights in telephone numbers." I asked well, if that is true, then in the event I want to take my very highly desirable number away from your company and give it to another carrier, what prevents your company (as the present carrier/owner of the number) from using the threat of taking it away from me as a way of 'persuading' me to continue with your company instead of your competitor? After all, you own it and I have no property rights, correct? The answer was this is true, however if the carrier were to seize the number in this way it would then be idle, and as your agent the other carrier would come to us and demand the number anyway. "Besides," said my contact, "we would get sued until Kingdom come for playing around like that; I think the way that rule (no property rights in number) is interpreted is to mean that as telephone systems change their technology and expand their numbering systems, etc that in the event the customer's number has to be changed in order to be compatible with the network the customer has no legitimate gripe with the carrier." I asked about your theoretical example above, and the response was that he could not imagine telco not getting a good and thorough suing if a number change like that took place for strictly financial, monetary reasons.

You can not use this with ZMODEM!! Z-modem is an 8 bit protocol, unless you establish an 8 bit Telnet connection, it won't work. Basic Telnet is a 7bit connection. Some Telnet clients support an 8bit mode (check your man page on how to start telnet in 8bit mode). Also agree with the above. Control characters are part of the problem too.

Remember how for years and years we could dial any number in 301/202/703 using any of those three area codes? You could reach any DC/VA/MD number using any of those three codes. How picky was the Bell System thirty or forty years ago about this sort of thing? Well ... old timers will tell you that not only were there very specific rules about who got what area codes; who got the ones with zero in the middle and who got the ones with one in the middle, but there was also a rule that the same prefix was never assigned in two adjacent area codes. That is, if 321 was a prefix in your area code, it was not used in the area code on any side of you. Why? Because 'community dialing' was considered important. Every state has one or two instances of cities or towns which straddle the state line or an area code boundary. Bell did not want these communities inconvenienced in their calling patterns. That was long ago ... such luxuries have been unaffordable for several years now.

Rabinowitz EDS/GM 8 320 5509 EDS/Saturn Sales and Marketing Team +1 615 486 5509 The {Nashville Tennessean} reported this morning (4-3-95) that legislation has been proposed at the state level, which if enacted, would prohibit the use of pagers by minors, except if there was parental consent. It was unclear from the article what would constitute proof of consent. If a minor is convicted under the proposed legislation, the penalty is to have one's drivers license revoked for a year, and have a requirement imposed to perform 50 hours of community service work. Additional provisions prohibit the sale of pagers directly to a minor, the penalty for which is a $2,500 fine. Apparently, however, a parent or guardian can purchase a pager on a minor's behalf. The legislation, in addition to the usual concerns about pagers being the primary means of communication among drug dealers, was prompted by concerns of parents losing control of their children. A father of a 14 year old girl reportedly contacted a legislator on the matter after the girl had been receiving calls from "undesirables," that the use of a pager by the girl had apparently been related to these calls, and after finding that the use of pagers by minors in Tennessee was legal. "We need a law. These beeper retailers have usurped my authority with my daughter and they are contributing in a way to delinquency because she is receiving calls from these people I find objectionable," the father reportedly told State Representative Henri Brooks (D-Memphis), the sponsor of the bill.

And I read someplace that an even more accurate way to keep the calendar in line with the seasons was to omit a leap year every 128 years. But the Gregorian, as noted, takes more than 3000 years to be off by one day. The Gregorian calendar was instituted in 1582, so it should have been right in line with the seasons then. (Many countries took longer to adopt it; Great Britain and its colonies, including the future United States, did not adopt it until 1752.) -------------- TELECOM Digest Editor's Note: Julius Caesar (or more correctly, perhaps, Gaius Julius who lived from 100-44 BC, a Roman general, statesperson and writer) had a fascination with the calendar although he made some awful mathematical errors in his decrees regarding same. He named one of the nice summer months after himself. The word Caesar itself probably comes from the French 'ruler' or 'emperor'; one to whom civil obedience is due; a temporal ruler. It would apply to any of the dictator/rulers in that time who succeeded Augustus Caesar (who also has a month in the summer named after him) -- or would you readers in Australia say a month in the winter -- heh! heh! -- I am so glad its your turn for awhile while we here get to warm up now; instead of the gas works cutting me for not paying my furnace/heating bill, now Edison can cut me for not paying for the electricity to run my air-conditioning ... ah, but I digress. Anyway, after meditation and consultation with his astronomers and others he realized that 365 days in a year was not quite accurate. Using the tools at his disposal he decided there had to be an extra quarter day tossed in each year to make things work out right. So the new calendar was devised according to his instructions. They went along that way for quite awhile, adding one day every four years to account for that left over bit each year. The error was not big enough to notice even over several hundred years. Well, along about the year 520 in the Christian era (although they did not call it that, they still used Roman era numbering) the Pope at that time got annoyed about something (in those days, and clear through the 16th century the Popes were just plain *weird*, there is no other way to describe them; the saints in the 13th-14th century were even more *weird*, but I am digressing again ... so the Pope called on one of his scholars and bright young men, a monk by the name of Dennis Aloysius (I think) and said "Dennis, figure out a new system of years to go by." Dennis thought about that for quite a while and after some serious calculations told the Pope that Jesus had been born in the 720th year of the Roman Era and that henceforth that would be known as year 1, and that therefore it was now the 520th year in the Christian era. The pope bought that argument and made his own decree accordingly. He let Julius and Augustus continue to have months each year named in their honor. There were a few other months named after persons real or mythical which he allowed to remain in the calendar and the leap year thing seemed okay, so he kept that part also; only the year number would change. There were days of the week to honor the moon and the sun; the pope left that alone also. But Dennis made some errors in his work also that would not be rectified or discovered for about 11 centuries. Fast forward a thousand years or so, and Pope Gregory has been told by his advisors and confidantes that the calendar is going to be adjusted again. As they explained it to Pope Gregory, Gaius Julius had gotten it all wrong: instead of a year consisting of 365.25 days, it really only consisted of 365.2422 days, or 365 days, 5 hours, 48 minutes and 49 seconds. As a result of that 11 minute difference each year unaccounted for in Gaius Julius' calendar, it has gotten way out of whack, being some several days short of where it ought to be. By the time they can enforce this on all of Europe however, several more years have passed. In 1582 -- I forget exactly what date -- a general adjustment was made throughout Europe with the calendar; several days were just chopped out to make up the shortfall. In England a few years later, King James decided to write a new Bible. It was to be that the version King James authorized would be truthful and more accurate than earlier scriptures, especially those that the earlier Popes had had anything to do with. He put Archbishop Usher in charge of the project, and soon the Archbishop and his scholars were busy at work. They thought it important to provide exact dates for all the various occurances in this new Bible they were writing for King James, and in the process of proving to the King that the world was created on Tuesday, October 8, 4004 BC at 9:30 in the morning, they discovered an error in the work Dennis Aloysius had done centuries before. It seems he had miscounted somehow and left out four years. Oh gosh ... well, said King James, we are not going to change this year from 1612 to 1616, we already changed the calendar once and dropped off all those days we were short, we are not going to add four more years. A few people including the Archbishop almost lost their heads because of that bad news they brought the King. They just decided they would backdate everything, and take ancient history and move it all back by four years instead as to *reported dates*. So they went through their scriptures and moved every date back by four years including the birth of Jesus Christ. This of course meant that Jesus Christ was born in the year 4 *efore hrist, and that seemed odd to King James and Archbishop Usher as it seems odd to me. Still, they decided to let it go, and if you look at the KJV Bible today -- still one of the best selling Bibles around, 380 years later -- the little references and margin notes come to Jesus' birth and refer to it as the year 4 BC, in other words he was born four years before he was born (?!?). Trivia, they said, don't bother us with that trivia. Just on general principles, England and her colonies in America did not go along with the adjusted calendar. England did not make the 1582 adjustment until 170 years later. By the middle 1700's though, this calendar dispute was getting awkward and embarassing for the colonists in the New World. After all, they still did some trading with Europe and other business with them and it was getting a bit weary for folks here to say it was Tuesday, May 1 while people in Europe were saying no, it is really Tuesday, May 12. Not only that, there was a movement afoot to change New Year's Day to January 1. Someone had thought, wisely, from long before that the perfect time to start the New Year was when spring started; a new year, new birth and all that ... so it has always been that March 21 was 'New Years Eve' and March 22 was New Years Day. For example, March 21, *1610* was followed by March 22, *1611* ... it was always done that way for however long. Wasn't that one of Gaius Julius' ideas also? ... I think so. Finally the Americans gave in and agreed to adjust their calendars also with the new year starting on January 1. September, 1752 saw the new Gregorian calendar take affect in America and England, and the calendar for that month looked like this: September 1752 S M Tu W Th F S Note that Wednesday, September 2, 1752 1 2 14 15 16 was followed by Thursday, September 14, 17 18 19 20 21 22 23 1752. We had to yank 11 days out while 24 25 26 27 28 29 30 Europe only knocked about 8 days out since extra time passed before we finally did it. This, they assured us, plus following the new rules for leap years would keep everything in good shape for quite awhile. The problem had been we were only entitled to pick up .2422 of a day instead of .25 of a day. When we did the pick up every four years, we claimed an extra day when we were only entitled to an accumulated .9688 of a day. That extra .0312 of a day we should not have would accumulate after a century (25 leap year days added) to us being .78 of a day away from where we should be. So by taking one less leap day every century, instead of being .78 of a day ahead, we would be .2512 of a day behind. It was that extra .78 of a day per century accumulated over all those years that we had to deal with finally in 1752. After four centuries of losing .2512 of a day each century, we come out to 1.0048 days short of where we ought to be, so we go ahead and take another leap year day, leaving ourselves only .0048 of a day out of whack. The exact rule we follow is that every four years is a leap year *except* if the year ends in two zeros *unless* the year (ending in two zeros) is also divisible by 400. The year 1600 was a leap year. 1700, 1800 and 1900 were not leap years; the year 2000 will be a leap year. As Carl points out, omitting a leap year every 128 years makes more sense; under Pope Gregory's formula we have to get all the way to the 33rd century before another arbitrary adjustment has to be made, but under the rule of skipping a leap year every 128 years we could go several more centuries later than that. Or, they could adopt *my* formula and never have to worry about it again: The rule of Saint Patrick (and you may think I am weird also, but I did not live in the 15th century so I am not as weird as *they* were) is this: every year at the stroke of midnight on New Year's Eve, we set the clocks back to 6:12 PM and have another 5 hours and 48 minutes of New Year's Eve partying. :) I have also thought about building a clock which had 74.5 minutes per 'hour'; it could probably be marketed in one of those fancy mail order catalogs such as Sharper Image. Marketed as 'natural earth time', it would be so cool to watch how every four years or so the 'natural earth time clock' would be nearly in synch with the arbitrary time shown on our 'real' clocks. Always *nearly*, never exactly; then the time on that clock would diverge widely from ours for another four years then begin to come in line again; closer than the last time, but still frustratingly different. Then perhaps once in our lifetimes the clocks would be just seconds apart ... as close as we would ever see them ... and they would begin to diverge again. I'd put the natural earth time clock in a case with a 'regular' clock and a caption saying 'the real time is ...' but we say the time is ...'. Here is your homework assignment for tomorrow: assuming the 1752 adjustment left us in perfect synch as of zero hours zero minutes GMT on Thursday, September 14, 1752 (which it didn't, but let's say it did), and the time now is commonly accepted to be five hours 54 minutes GMT Tuesday, April 4, 1995, what would be the 'real' earth time right now? Day, date, minutes and hours please.

In Ohio dereg means just that, your friendly local cable tv company will be on your doorstep wanting your telephone business, or perhaps your friendly long-distance company will make you a calling circle deal that includes your local service or maybe a new company who is a small player that wants to be a bigger player. Of course your local phone company will also be on your door step wanting your long distance and your cable tv business as well. (Hope you have a big front step!)

PAT Well, PAT it exists. Here in Germany, for instance, Cyberlink is offering a service where you dial a toll-free number and -- armed with your PIN and destination phone number -- can dial anywhere in the world for less than what it would cost you if you dialed direct on your cellular phone. Depending on your billing plan with your card provider you can even save on cellular calls made _within_ Germany. Something like 20 to 40 percent. (Being cheaper on international calls made with your cell phone in Germany is not hard, really, so I'm not even going to elaborate on that.) But it is not true Callback, of course. And -- in Germany you only pay for _outgoing_ calls made with your cellular phone. You don't pay for toll-free calls though, but I think it won't take long before the network providers realize that they are losing business there too and change the tariffing structure accordingly. BTW, international callback from Germany to the US with a US Callback service I recently subscribed to is (slightly) _cheaper_ than a phone call _within_ Germany at the most expensive time (8 a.m. to 6 p.m.) to the most expensive place (distances farther away than 30 miles). So, when you don't pay for incoming calls, callback can be extremely cheaper.

The techs at the NOC are very knowledgeable and are pleasent to deal with. We don't have any plans of using the internetMCI software at this time.

Sounds quite suspiciously like the "Rabbit Phone" in the U.K. They've gone out of business, but for a while you could buy a telephone which would operate like a cordless in your own home, but when you were away from home could be used to place *outgoing calls only* anywhere within range of their little rabbit signs. These would then be billed to you at rates somewhat higher than a normal payphone but significantly lower than a cellphone. They were still in the process of ramping up on access points when they went out of business, but they had access points in major downtown areas, including on the platforms of many of the major London Underground stations, some of which are deep enough that you'd probably get a lousy cellular connection unless they also install a mini-cell.

During rush hour, you would think that with everyone in their cars usage would be high. In fact it's not. What is usually the case is that nobody is in the offices to take the calls.

Charging for yellow-pages-only volumes doesn't surprise me at all, because yellow pages are paid for by advertisers and those advertisers won't pay for circulation outside the areas they intend to serve. In fact it was the practice in the Bell System pre-1984 to print small quantities of white-only versions of all books that normally combined white and yellow sections, specifically to be given out outside the actual areas being served. (Thin white-only Jeffersonville/Clarksville/ New Albany books used to be seen fairly often around Louisville, and thin white-only Louisville phone books were even more common in southern Indiana.) Obviously in the case of separate yellow pages it was easy to just send out the white pages. I suspect the charge for out-of-area phone books (I mean local calling area, not necessarily Judge Greene's LATAs) is another result of divestiture; before then, since operating companies never competed against each other (even between Bell and GTE), they cooperated freely in many ways including exchanging phone books to provide to customers. Now that the RBOCs are competing in several respects they aren't exactly inclined to treat each other as siblings, so charging for directories provided to other LECs was an obvious step and charging customers is the next one. ------------------------------ End of TELECOM Digest V15 #190 ****************************** Received: from delta.eecs.nwu.edu by MINTAKA.LCS.MIT.EDU id aa25341; 10 Apr 95 18:04 EDT Received: by delta.eecs.nwu.edu (8.6.12/8.6.12) id JAA27577; Mon, 10 Apr 1995 09:12:17 -0500 Date: Mon, 10 Apr 1995 09:12:17 -0500 From: TELECOM Digest (Patrick Townson) Message-Id: <199504101412.JAA27577@delta.eecs.nwu.edu> To: telecom@eecs.nwu.edu Subject: TELECOM Digest V15 #191 TELECOM Digest Mon, 10 Apr 95 09:12:00 CDT Volume 15 : Issue 191 Inside This Issue: Editor: Patrick A.

I've commented in the past on the desirability of area code overlays as opposed to splits to deal with number growth problems. While forced 10 or 11 digit dialing for local calls may seem onerous to some, it has long been effectively a fact of life in most metro areas with multiple NPAs (area codes) if you were calling more than a short distance across the city! Here in L.A., it's virtually useless to give anyone less than your full 10 digit number -- they could need it to reach you from the nearby NPA across the street. The local telcos (at least in the L.A. area) have been getting their act together in terms of permitting the inclusion of 1 + area code even for calls within the same NPA, which makes it much easier to dial in a uniform manner regardless of where you happen to be at the moment. I am very disappointed, however, to see the wireless companies lobbying the state utilities commissions and the FCC to force telcos to engage in more splits rather than use overlay codes. The wireless folks are claiming that the overlays are "discriminatory". Hogwash. As I mentioned above, in the high-growth metro areas you need to dial 10 or 11 digits anyway to reach other than your immediate area. All splits do is cause incredible expense and inconvenience for the folks forced to move to new codes, particularly businesses. In some areas, split rates are so high that some subscribers are being forced to change area codes every few years -- and the rate will do nothing but increase. It's time to recognize that the convenience and concerns of *all* telephone subscribers are more important than the perceived "status" of particular area codes and 7 digit dialing to the well-heeled wireless telephone users, a user group that represents only a fraction of the overall telephone subscriber population. Overlays are the only practical solution to deal with telephone number growth problems. The FCC and state commissions should *encourage* the use of overlays whenever possible, and discourage the use of further splits, particularly in areas where subscribers would be forced to undergo a second split from their original codes. The continued use of splits in these situations can only lead to increasing confusion and costs for *all* telephone subscribers. --Lauren-- ------------------------------ From: brown@NCoast.ORG (Stan Brown) Subject: AT&T $5/Month Minimum Date: Mon, 5 Apr 1995 01:48:21 GMT Organization: Oak Road Systems, Cleveland Ohio USA Today in my bill from AT&T I got a flyer that said AT&T will begin charging $5/month minimum for long distance, possibly as early as the next bill. I called the number on the flyer for questions, and the rep on the other end confirmed that "to serve you better" the minimum would be billed even in a month when I had no long distance charges. As it happens, the line involved almost never dials out long distance; I use it for local data calls almost exclusively. So this is quite a bad deal for me. I called Ameritech and found that a change to "no default LD provider" is free on my line, so I made that change. This suggestion might be helpful to other light users of AT&T long-distance service.

Kimberlin" <0004133373@mcimail.com> Subject: NC Solons Complete Local Competition Bill On April 5, the North Carolina House passed by a 110-0 vote the bill intended to initiate local telephone competition across the state. The bill it passed was a version slightly modified in the NC Senate from the House's first version that was also passed in a landslide. Once the bill is signed into law, competition for local telephone services will be permitted in all areas of the state now monopolized by the state's four largest telephone companies. Thus, North Carolina locations now covered by Southern Bell, GTE South, Carolina Telephone and Central Telephone. Those four companies presently operate about 90% of the telephones in North Carolina. Areas covered by the 20-odd smaller companies having less than 200,000 access lines per company will remain regulated monopolies unless they opt to engage in competitive operations outside their territories. Should any excercise that option, their present monopoly will be opened to competition. That provision was the way NC legislators decided to try protecting "universal service" to rural and sparse areas of the state. The present intended date for the start of competitive operations in North Carolina is July, 1996. Meantime, rate regulation of local phonecos in NC is to be changed to rate cap regulation only one year in advance of competition. Across the state, cable TV companies, long distance carriers and competitive local access carriers are eyeing their new markets. In Charlotte, Time/Warner Cablevision is well underway converting its local cable trunk routes to fiber while also starting up a competitive access firm called Charlotte AXs. Charlotte's three-year-old extant competitive access firm, ICG Access Services, Inc., already has 60 route miles of fiber installed all over the city. Similar anticipatory moves can be found all over the state. Proponents of the change already herald the results from competition at Rochester, New York, where it has been claimed local dial rates have dropped 11 percent in only three months since competition began there. While they look forward to similar reductions in North Carolina, territories of the remaining small companies are not expected to have rate reductions as a result of competition in more dense areas. Perhaps the most astonishing turnabouts have come from those who until even a year ago protested bitterly that local telephone competition could never be workable in the U.S. model. Until it appeared lawmakers were serious and would not be deterred from initiating competition, constant cries that it would be a threat to reliability and quality of service; that it would result in loss of "universal service" and ultimate rate increases to rural areas were heard at every hint of opening the local exchange to competition. With passage of the bill, some completely opposite remarks were heard. Clinton Metcalf, Southern Bell's NC state spokesman, was quoted as now saying, "This bill is really one of those rare instances where nobody loses. Consumers win because it brings more choices and new products to them faster. Local telcos win because because pricing flexibility gives us the ability to respond to the inevitability of competition. And competitors will have the ability to compete." As published in the report on passage of the bill: "Such words sound remarkably benign, given the local telephone carriers' fierce opposition to competition as recently as two years ago." Now what remains to be seen is if the old Telco Tigers can really change their spots and compeete in a truly open market ... and if the potential competition really are cats with different spots, or if the proposed "new products" will only be a duplication of the present, perhaps with a downward price shift. ------------------------------ Reply-To: bob@flatwater.win.net (Bob Keller) Date: Mon, 10 Apr 1995 07:50:52 GMT Subject: FCC Information On-Line From: bob@flatwater.win.net (Bob Keller) Here is the text of a Public Notice issued yesterday, describing the on-line availability of of FCC information: April 6, 1995 FCC Information is Available Online Most announcements and actions of the FCC are available on the Internet and other electronic delivery systems.

I assume it is North Carolina State University, considering the reference in the text and the return address, but I wish the name of the student newspaper had been included. PAT] Telephone campaigning method questionable Supporters of John O'Quinn used voice mail to campaign for him in the runoff election. By Josee Daoust Assistant News Editor New Student Body President John O'Quinn should have cleared one of his campaign methods with the Student Government Elections Board, said Elections Board Chair Sean Bullock. Several N.C. State students living on campus received a voice mail message reminding them to vote Monday and Tuesday and suggesting they vote for the then Student Body President Candidate John O'Quinn. The Student Government Campaigning Policy section of the student body statutes says any alternative campaign idea not addressed in the campaign policy must be approved by a majority vote of the elections board. "[O'Quinn] must come to the elections board with those strategies -- he has not," Bullock said. Free-Expression-Tunnel painting, posters, handbills, sandwich boards, smokers or speechmaking are considered viable campaign strategies. NCSU Telecommunications manager Chris Parker said using voice mail as a campaign tool was potentially annoying to some students. "Personally, I think that this is a bad way of [campaigning]. This is one of the downsides of providing voice mail," said Chris Parker, manager of Telecommunications. "It's up to Student Government to decide whether it wants to reject this idea. This person made a bad choice." But O'Quinn said he has done nothing wrong. "I asked people to make phone calls for me, but told them not to use voice mail," O'Quinn said. "It is my understanding that there is no problem with that. Everyone has access to a telephone." Student Government Operations Chair Chris Love also said it was acceptable to use voice mail in campaigning. "As far as I know that isn't a violation," he said. A representative of the O'Quinn campaign said the phone campaign was organized for the purpose of getting people out to vote. One of the phone messages, which provided a phone number, said to call for more information about the O'Quinn campaign. "We were asked [by O'Quinn] to call the people who signed their name to the petition against tuition increases," said Angie Singleton, a freshman in aerospace engineering, who sent O'Quinn campaign messages via voice mail. The petition drive in question was conducted on March 22 and 23 by O'Quinn and members of the NCSU College Republicans. But some people who didn't sign the petition still got messages. "John O'Quinn, who is also a resident here in Sullivan, is one of the candidates for student body president," said Derek Miller in a voice mail message to a Sullivan resident who did not sign the petition. "I really believe John is the type of leader we need. I would encourage you to step out today or tomorrow to vote for John O'Quinn as student body president." Singleton said she was not part of O'Quinn's campaign staff, but wasn't sure if O'Quinn considered her a member. "If I had known this was a violation, I would have never done it," Singleton said. Singleton's roommate Donna Liffiton said they were instructed to call the people who signed the petition and thank them. They were told to mention O'Quinn's name because he organized the petition, Liffiton said. Max Anthony, a junior in business, received a voice mail message as well as a phone call that he answered. He got the latter phone call at 1:45 a.m. The voice mail message informed Anthony of the runoff election and gave him a phone number to call if he had any questions about the O'Quinn campaign. O'Quinn's campaigning methods have been questioned before. O'Quinn would not comment on whether he received a warning from Elections Board Chair Sean Bullock for one of his supporters sending e-mail on his behalf during the initial campaign. "That's between me and the elections board chair," O'Quinn said. "I could tell you, but I am not going to." The Student Government Elections policy states that using university supplies for a campaign will result in immediate disqualification. ------------------------------ From: klarer@spdcc.com (Steve Klarer) Subject: SLIP Hangs up Mac Organization: spdcc.com Date: Sun, 9 Apr 1995 19:51:01 GMT I' m reposting this since the original has scrolled off my sytem and I assume it' others as well.

Developed by DLF Universal Ltd, a large real estate Company, the township is located on Delhi's southern border and is one of the posh places to buy a house these days. About 50% of the land area has been built over so far, and although most plots are sold at present about 1,500 households have moved in. The population is expected to grow to about 40,000 families over the next 5 to 10 years. DLF is build all the support infrastructure for the residential and commercial areas. As a private township, they don't have to bother much about government rules concerning mixing cable and telephony, which is what they want to do. They don't lack resources, but want to ensure that what they wire in right now will be made the most of. They recently invited bids from companies interested in designing, supplying or operating the whole or part of the network. While they would be delighted if a company adopts the township, full of information-hungry yuppies with computers, as an experiment, they are quite willing to simply pay for it all.

Tamkin) Subject: Number Assigned to New Illinois NPA Date: Wed, 12 Apr 1995 22:53:54 CDT According to WMAQ-TV news tonight, the new area code carved out of 708 for the northern and northwestern suburbs of Chicago will be 847. Their source was Ameritech. Permissive dialing runs from January 22, 1996, through April 20, 1996. 847 is a poor choice -- it borders on another NPA that begins with the same digit (815) and another bordering NPA has prefix 847 in use not far from the boundary (312's VIrginia 7 in Chicago-Lafayette), but we're stuck with it. At least Lafayette is beyond untimed call- ing range of any part of NPA 847. It would have been better to select something that is not in use as a prefix in 312 and whose appearance as a 708 prefix is in the area that will stay in 708 after 630 splits off in 1998, which has virtual- ly no border with 847, but there will be no bordering problem after 312 splits (also in 1998) if Lafayette ends up in a different NPA from the exchanges in 312 that abut NPA 847. For the discontiguous NPA file: unless there are some phone number changes forced on customers in Rosemont and Norwood Heights, 847's territory is likely to be in two separate pieces and that of the post-split 708 in *four*. 630 will be a single geographical area, and removing it will still leave 708 in four parts.

Bellaire) Subject: NPA Cross Reference For the past couple of years Robert Rickets has been compiling a MSDOS cross reference program for North American Numbering Plan exchange codes. This shareware program is available on the CompuServe TELECOM forum. The new version include the new 360, 334, 520, 630, and 970 NPAs and includes both MSDOS and Windows versions. It provides city name, state, county and lattitude logitude information and can calculate distance between exchanges. On CServe search for npad51.zip for DOS or npaw51.zip for Windows. The dos version is on ftp.cica.indiana.edu (and it's mirrors) in the /pub/pc/win3/desktop directory. npaw51.zip was also uploaded but I have not found it there yet. Both files were also sent to garbo.uwasa.fi and should appear soon. I hope you don't mind this shameless plug. I have no connection to Mr. Ricketts except being a happy registered user.

When I saw a message in TELECOM Digest claiming that AT&T was implementing a new "minimum usage charge" of $5/line (e.g., you get charged $5 even if you never make a long distance call), my immediate reaction was to wonder if someone had misunderstood something, or was somehow confused. I've always respected AT&T, and it seemed difficult to imagine that they would shoot themselves in the foot in such a lame and idiotic fashion. I spent a good chunk of time today trying to track down the facts. The result: As far as I can determine right now, AT&T has *indeed* fired a number of shots into their own foot. Un-be-liev-able. Here's what I've been able to piece together so far. It's accurate as far as I know, but I have more inquiries pending and I'll pass along anything else I find out. 1) No minimum charges would apply to residential lines (as far as I can determine right now). 2) A minimum charge of $5/month/line will apply to all separately billed business lines that have AT&T selected as their carrier. This will just suddenly start appearing on bills shortly. Surprise! 3) AT&T is suggesting that business customers aggregate their lines in various ways to help avoid the charge (aggregated lines -- e.g. via Custom Net or SBA, etc. apparently share a single $5 minimum between all lines). When I suggested that this new policy was unbelievably idiotic, each rep I spoke to *agreed* with my analysis, but said in effect, "that's what they've decided to do anyway". Point (3) above is worth a few more words. While it's true that businesses can aggregate their lines in various ways, the fact is that keeping even a few lines on the proper plans at the proper times can be a lot of work. Due to problems at the long distance carriers, the local telcos, and the communications between the two, it is common for lines you thought you had on a plan to not be there, or to drop off unexpectedly. Sometimes it can take literally months (!) for lines to get into the correct status, even assuming a business rushes to join an aggregation plan as soon as lines are installed. Under the new AT&T plan, it appears that as soon as you select AT&T for your business line carrier, the $5 minimum for that line starts to apply. Of course, since most people make their initial carrier selection through the local telco when they order a line, I suspect most business folks who just say "AT&T" when asked for a carrier choice won't have a clue about the minimum charge until it shows up on their bill. Overall, this whole idea has to rate as one of the biggest mistakes AT&T has made in the post-divestiture universe -- one that will haunt them for a long time to come, unless they give up on this ill-conceived idea with a minimum of delay. Shame on you, AT&T. --Lauren-- ------------------------------ Date: Wed, 12 Apr 95 08:46 EST From: National Electric Telephone <0006348890@mcimail.com> Subject: AT&T $5 Minimum Monthly Charge I would highly suggest "pic'ing none" with regard to a long distance carrier to avoid this charge and then dialing a 10XXX access code when you need to make an interLATA call if you don't make many interLATA long distance calls. If you do make a lot of interLATA calls switch your PIC to a better carrier. AT&T is really getting outrageous. First they charge for whole minute increments rather than six second billing. Now they want to implement a minimum $5 charge. This is getting out of hand. Their answer to competition seems to be clobber the public with advertising saying "We're great." while at the same time raising their rates to outrageous levels. K.

Does anyone know how this will affect equal access codes? If I had a non-AT&T company as my default carrier, but used the 10288 code for a call, would I then be billed a minimum of $5 for that month from AT&T? This seems to work against AT&T getting casual business from customers using equal access to use multiple phone companies. I hope this doesn't spread to the other LD carriers.

In Canada only the telco can supply payphone service. This may change in the future, but as of today those are the regulations. Thus, Bell Canada has a monopoly on payphone services. My goal is to discover whether they are providing the hospital with competitive North American commission rates. Our current contract is a five year contract from July 1992 to July 1997. We currently have a total of 88 payphones on two campuses. Together, in 1994, they generated (after taxes and settlements) a grand total of $258,845.00. Our share of that revenue was $22,194.00 or 8.57% of the net revenues. Daily Revenue per Telephone for the 88 payphones... below $3.25 22 phones between $3.25 to $9.00 36 phones between $9.01 to $15.00 22 phones between $15.01 to $25.00 5 phones over $25.01 3 phones Recently, I ordered out ten of the 88 payphones because of they generated no revenue for the hospital. The other payphones are under review. Bell Canada claims the cost to provide service per day is $6.00/day per payphone. This is based on our current average commission rate of 8.57%. They also claim a Millennium payphone costs several thousand dollars. I find this hard to believe! 75% of the calling is made with cash. 25% of the calling is made with credit cards, debit cards or by other means. The non cash calling has held around $700 per month over the last twelve months. Surprisingly it has not gone up! Commissions are paid on a sliding scale per payphone. The following is the commission scale: Less than $3.25 per day 0% commission. $3,25 to $9.00 per day 8% commission $9.01 to $15.00 per day 9 % commission $15.01 to $25.00 per day 10% commission. $25.01+ 11% commission. In our case, the commissions average out to 8.57%. Bell Canada supplies, at their expense, the Millennium payphones to all locations. They also supply the telephone line, phone books, and shelves (F450T) for the phones. In addition, they pay the labour to install the phones, the required cable, and all repair and collection costs. The hospital is responsible for any construction costs incurred by the installation of the phones. The hospital must also supply conduit to the payphone. There is a possibility that the hospitals in the city may one day merge. This could add 50-100 more payphones to the contract. I suspect payphone competition will soon arrive in the Canadian marketplace. This may give us some leverage to reopen our contract before the expiry date. The hospital is being squeezed for revenue generation and I am making every effort to increase our income. This message is not intended as a anti-telco/anti-Bell message. I only want to make sure we are being treated fairly. Thus, my question is: If we have the chance to reopen our contract is this a good deal for North America or should the revenues to the hospital be higher? I would be interested in your reader's comments!

Both phones are serviced by GTE in Long Beach, CA. One phone is a pay phone at a business, the other is a local residence using the Measured Pay Service (one outgoing local call per day for no extra charge). A call *was* made from the residence phone later in the day, so if we could even prove that the later call was made and was *not* charged (meaning it was the first local call of the day), it would help our case. We already had a subpoena for the records on these two numbers for the date in question, but we did not get the information we need. I have been told by people familiar with telco operations in other localities that more detailed information is available, but not provided unless specifically requested *by the proper name* because it is more work. I would like to know the terminology GTE uses to specify this type of search. Thanks in advance.

According to Denis Gross, a telecommunications consultant with analyst firm BPA, CDMA does not appear to be working in trials, because of problems caused by signal reflections from structures. Gross said 'CDMA offered a lot, but is proving difficult to implement in urban areas. A handful of operators are trying to get it to work, and they will continue to lobby for it. They say that GSM is noisy at 1.9GHz.' @copyright {Electronics Weekly} Now, we all know how ~in theory~ CDMA offers capacity increases of the order of 20-30 times that of TDMA. But have we seen it's real limitation, ie too many multipaths causing problems. I have seen Qualcomm's field test results and they are heartily impressive, but I have to wonder whether they would be better letting IS-95 die gracefully and started working towards the third generation of telephony, ie 10MHz BB-CDMA. At this moment in time it seems that only Korea and some Western states in the US will implement IS-95. Comments please.

Numerous things have happened here including the fiasco with the sendmail last week which caused issue after issue of the Digest to bounce and disappear, or get delivered twice to some people and not at all to others, etc. I think that has been fixed. At least I have not had any complaints about the issue sent out earlier this week. Now compounded with that is the fact that I have been literally buried in subscription requests this past week. Twenty to thirty new names per day are being added to the mailing list, and I don't know where this is going to stop. The mail continues to flow in quite heavily, and the changes made last week in sendmail also caused the autoreply mechanism to break down, or at least to not properly filter and sort incoming stuff, meaning lots of subscription requests were mixed in with articles for the Digest; lots of mail-daemons on undeliverables to go through, etc. I have been getting about 100-150 mail-daemons per day to be sorted through. These in large part come when the name servers get hosed, which seems to happen with regularity. Each issue of the Digest is now taking almost an entire day to get delivered. I'll check the mailqueue late Thursday night and still find this issue you are reading now in the queue marching along name after name. That is rather dismaying, because the larger the list gets the longer it takes for the folks *on the end of the list* to get their copies. The volume of submissions for the Digest is running about 200 per day the past couple of weeks. I don't like to do it but periodically I have to go through the waiting mail and, take several *hundred* items and simply toss them out unread. The sad fact is I was/am totally unprepared for the volume of stuff coming through; and I knew enough about this to assume there would be plenty of mail. I just want to let you know that if I seem short at times in personal answers sent out, or if you get one of several form letters I mail regards subscription requests; or if you don't get an answer at all you should not take it personally. For all intents and purposes, I no longer have any control over the mailing list, it has gotten that large and unweildy. Thanks very much for YOUR continued support as the Digest continues a growth spurt like I have never seen before. I am thinking of starting a fax edition, but the cheapest I can the cost down to is about a dollar per issue, maybe 75 cents. Do any of you want to get it delivered that way? Please let me know.

I am agruing the point that price alone does not a happy customer make. I am also trying to separate it into mandatory (e.g. PUC requirements) and competitive. Narrowing it down, I am only looking at business and residential switched services. Specifically: Provisioning interval (service request to installation of service) Trouble resolution - the telco will fix your trouble in X business hours. - trouble report to resolution of trouble - what happens if trouble is not fixed in X time (i.e. credits) Customer Service - trouble reporting is available X hours a day (e.g. some RBOCs have 24 customer service, is this offered because they are being customer oriented, or is the state PUC telling them to do so?) - Will someone pick up a repair call in X rings? (I've heard that, in some areas, customer service centers are set up so that if a call rings more than 4 times, it will bounce to another center.) I am looking to separate it by service (A) per regulation and (B) per competition. As an example of a title for (A), I found that the Maryland PSC had it titled: Title 20 Public Service Commission Subtitle 45 Service Supplied By Telephone Companies Chapter 05 Service Standards I got 9 pages of regs for MD. For (B), I've found some Web pages for Ameritech & AT&T that say customer service is important, but I was hoping that I could get some "company promises to their customers" that might be in a Marketing broschure.

With their vast library of RATW audio tapes, 232 separate broadcasts, featuring interviews and music from the 70's World of Rock, they'll keep you entertained through a variety of mediums well into the next century. RATW captured the attention of its faithful listeners from its inception in 1974. Throughout the next four years its following multiplied exponentially. The weekly syndicated show, which ranged from an hour to an hour and a half, teamed up with Lipman's monthly rock music newspaper R.A.T.W., and carved out a niche in radio syndication. It started as an outgrowth of a recording studio Lipman had in Boston. This followed his stint in national promotion for Elektra Records. The studio, Music Designers, was where he produced George Thorogood's first recording, as well as RATW. Lipman also operated an advertising agency, handling radio accounts for recording companies, such as Warner Bros, Atlantic, Elektra, and five retail record stores.

(1-800-827-6364) Reply-To: mstrandrew@aol.com (MSTRANDREW) I received post card mailing from ATT which advised me that all current UK STD codes will need to be prefixed by "1" starting on April 16, e.g. 071 becomes 0171. Also, the cites of Leeds, Sheffeld, Nottingham, Leicester and Bristol are being assinged new codes (113 through 117, respectfully). Also, each of these cities' local 6 diget numbers are being expanded to 7 digets. 6 diget numbers in Leeds, Sheffield and Leicester will need to be prefixed with a "2" and Nottinghame and Bristol with a "9". I am assuming the this change is being made to accomdate more telephone numbers within the current network. In the back of my I remember reading/hearging that there was a plan to change all numbers in the UK to a uniform length of 10 digets, but I could be wrong. I would be curious to learn the rationale behind the change if anyone knows. ------------------------------ Date: Thu, 13 Apr 95 08:24 EST From: Robert A. Voss <0002120410@mcimail.com> Subject: 500 Numbers Will Remain Blocked The industry has been wrestling with the problem of unblocking of 500 numbers by hotels, payphones, and PBXs. As of now, you can only count on making 500 calls from your house, or by using the "right" credit card, right being the same as the company which has issued the 500 number. Soon there will be many people trying to offering 500 services. There will continue to be problems until the industry solves a basic problem, that of billing. Until the cost of the call is known, only from the digits dialed, AT THE TIME THE DIGITS are dialed, will 500 service get universally unblocked. PBXs, payphones, and credit card systems cannot understand voice messages prompting people to "push #" if you are willing to accept forwarding fee of $1.50 a minute or whatever. Only when a bill arrives at the end of the month is the cost of the call known. The wise telecom manager will not accept unknown cost calls. Therefore blocking will continue.

Well, let me add the reasons why I switched from AT&T to the above. After an evening of watching about 25 commercials from AT&T telling me how wonderful they were and how terrible everyone else was, I realized that my L.D. fees were being used to by them to annoy me. As their customer, I was helping to pay for those commercials. Of the big three, Sprint seemed to advertise the least and were the most tasteful about doing it. So, they've had the business ever since and done a good job. I don't know if Sprint has saved me any money or not. I don't particularly care. And I didn't care that AT&T probably had the highest rates. I have a simpler outlook: Any advertiser that irritates me (through too much or too obnoxious advertising) causes me to notice and avoid business with them. Now, as a non-AT&T user, I'm no longer helping to pay for the annoying and abundant AT&T commercials. I just sit back, hit the "mute" button, and ponder thoughts like "the i plan is for idiots". Perhaps the monthly $5 fee will help provide even more commercials. I really wonder how many people leave AT&T because they're so tired of the commercials? Am I alone or is this a widespread? If I'm one of many, I wonder if AT&T will ever recognize that their current advertising techniques are like "pushing with a rope". ------------------------------ From: dgc@ccrwest.org (David G.

Overlays are the only practical solution to deal with > telephone number growth problems . . . What about eight digit telephone numbers? These could be achieved by assigning a consecutive block of (new) area-codes to a given area with some extras allowing for growth. For example the sequence of eight new area-codes 322-329 could be assigned to the LA metropolitan area. Instead of dialing 132x-yyy-zzzz, the user would simply dial x-yyy-zzzz. For smaller areas, such as the San Diego metropolitan area three consecutive area codes, all beginning with the same two digits could be used. Smaller areas could stay with seven-digit dialing. Area codes for areas with seven-digit dialing would be three digits (plus leading "1") and those for areas with 8-digit dialing would be two digits. This system with more variation in lengths of the area codes and local numbers is used in Europe and many other places. It works well. David G.

It has gone beyond that. They've managed to get this provision written into the bill pending in the Senate to amend the Communications Act of 1934. As currently written, the bill (in its section 301) would add a new section 261 to the 1934 act, which, among other things says: 261 (c) (2) OVERLAY OF AREA CODES NOT PERMITTED. - All telecommunications carriers providing telephone exchange service in the same telephone service area shall be assigned the same numbering plan area code under such guideline, plan, or rules. This is supposedly for the purpose of ensuring neutrality once local exchange competition is implemented, so that new entrants in the market will not have to require their subscribers to dial more digits than dialed by subscribers of the existing carrier. If this is adopted, overlays will become *illegal*. Personally, I think overlays are a good thing, so that individuals and companies don't have to spend millions of dollars reprinting stationery, etc. What I object to most about overlays is how they have been actually implemented -- they don't follow established dialing procedure conventions, in that they require ten-digit dialing between the overlaid NPAs -- the 713/281 overlay in Houston does not even permit 11-digit between them. It is very difficult for prepackaged software to know whether inter-NPA calls should be dialed as 10 or 11 digits without a huge database. My understanding is that the state PUCs are the ones forcing this, because of some notion that the leading "1" implies a toll call, and the lack of a leading "1" implies a non-toll call. Of course we all know that isn't the case. California has gotten it right, permitting 11-digit dialing of local calls not only to other NPAs but within the same NPA, whether the call is toll _or_ local (i.e., you can dial a call to anywhere in WPA 1 as 11 digits!!). I agree with Lauren that the FCC should encourage, if not require, all state PUCs and telcos to enable universal permissive 11-digit dialing.

For normal residence and business numbers, I do would not want overlay codes whatsoever. An area code/exchange should refer to a unique geographic neighborhood.

Bittorf) Subject: Re: The MATHLINE Project X-Organization: America Online, Inc. (1-800-827-6364) References: In-Reply-To: As the manager of MATHLINE for Thirteen/WNET in New York, I will fill in some of the gaps that the responder in Cleveland so aptly covered. Mathline came about when the government was looking to fund projects which would have U.S. students become first in math by the year 2000. Mathline, proposed by PBS, matched that goal in its vision and design. The National Council of Teachers of Mathematics (NCTM) was the guiding principal of the project. The NCTM standards are a new approach to learning math. Avoiding the typical methods of students memorizing formulas and math concepts, NCTM encourages teachers to have students learn math by showing how percentages, geometry, algebra, etc. are applied in day to day living. The student then feels motivated to learn their math because they see a direct relation between math and their own lives. Thirteen, WNET produced 25 videos of exceptional math teachers from around the country, demonstrating NCTM lessons in the classroom with their students. The videos were then distributed to the teachers selected by the participating public television sites around the country. Since most staff training relies on teachers staying after school or traveling to conferences, a computer network was created to link up all participating teachers to a mentor teacher who would serve as their "professor". After viewing the videos, and trying out the recommended strategies in the classroom, Mathline participants then go online to discuss the outcome and seek suggestions. In New York, seven schools were provided with Cellular phones and laptop computers (due to the generous funding from the CTIA Foundation and NYNEX) to ease the problems to modem access so common in most schools. The project was launched with a teleconference in the fall, and a midway conference in January, produced by Thirteen/WNET. The result so far? Even though we had 25 enthusiastic participants at the beginning of the project, about 75% kept with it (not a bad percentage overall). The access to a modem and a phone line was problematic and had something to do with some teachers losing interest. Others just didn't want to take the time to stick with it. The active participants made the idealism of the project work. They tried out the new strategies, saw how the students developed a new love for mathematics, and the teachers learned how to apply new ideas in the classroom. The sharing of ideas on the PBS Mathline network were wonderful brainstorming sessions. Our facilitator (mentor) is a very motivating leader for the participants. The cellular phones and computers have not reached their potential. For most teachers, the technology is given about three tries. If it is inconsistent, the user loses interest. Since New York has many physical obstacles for clear reception, I have been working closely with NYNEX to provide better antennaes. For a new approach to providing ideas to teachers and helping students improve their math skills, Mathline is a step in the right direction. The technology solves the problem of teachers not having time for staff development. It lets them chose the time (and with the cellular/laptops) and place for learning new teaching strategies. With all new approaches and technologies, it will take time before telecommunications becomes the first research tool teachers turn to for ideas. Those that are already accustomed to it are believers and have been wonderful trainers themselves. Bruce Wynn Director of Training Thirteen/WNET (212) 560-2804 ---------------- Bradley J.

With the involvement of Prentice Hall in this edition, the work may see a wider distribution. This work is a fairly bare bones and no nonsense guide to the Internet. The book is orderly, and the explanations and illustrations are clear. Each chapter covers a single topic. Most chapters end with additional references, most often online materials or sources. The work is well researched and highly competent in most cases. There is, in the early chapters, a gracelessness to it which lacks any kind of appeal. What humour there is tends to seem somewhat contrived and sanitized: a topic on the hardware that connects computers on the Internet is subtitled "Router Rooters: 'Go Internet Go!'" Nevertheless, it is a thoroughly researched and valuable reference for those interested in using the resources of the Internet. Section one, which is also chapter one, is a brief introduction to the Internet. There is minor mention of the technologies and organizations involved in the Internet, as well as brief mention of Fidonet and UUCP. The bibliography is a very solid list of valuable titles, but would have had significantly more value with some annotation. Section two covers the basic tools and functions of the Internet. The topics are well chosen, starting with email, mail servers, mail gateways to other networks and systems, telnet and ftp. Chapter four discusses mail etiquette. This section, I am happy to note, gives more space to the topic than is usual. In the end, though, it comes down to a list of rules that reduce to "keep it short, keep on topic, be complete and don't mess up." It would be nice to see one of these essays tell people how and why flame wars start, which might help to avoid them. Chapter eight, following ftp, deals with file compression and archiving. Section three moves into the next level of sophistication, in terms of communications, with group discussions. As the book puts it, these are the "Community Forums" of the net. Chapters nine, ten and eleven deal very clearly, completely and usefully with Usenet, BITNET LISTSERVs and Internet mailing lists. I am noted for highly critical reviews: I find nothing of any substance wrong with this section, and recommend it highly and without reservation. Once again, the end of each chapter gives useful directions on how to find out further information, particularly the specifics of various LISTSERVs and mailing lists. Section four starts to look at the resources of the Internet as a library, with electronic journals, books, catalogues and data bases. Chapter fifteen is very similar to the catalog section of various works with listings of sites and resources by topic. Section five deals with exploration and retrieval tools, such as archie, gopher, WAIS, WWW and directory services. The final section contains specialized interests, becoming an information provider on the net, the use of the Internet in public education, health related issues and access to supercomputing facilities. The chapter on providing information is excellent, giving, very briefly, a background and detailed overview which is more reliable than those in works dedicated to "doing business" on the Internet. (A concise introduction to HTML would be a valuable addition.) The book concludes with several appendices. The most interesting are likely Appendix A, which gives suggestions of online sources of information about the Internet, and, B, which gives a short list of Internet access providers and methods. The glossary is very well done: not overblown with imposing numbers of entries, but good explanations of the important terms. The unprepossessing beginning of this work hides a very carefully researched and well organized reference for those wishing to get into the Internet and its resources. Unfortunately, this most recent edition does not show much development from the previous one. I am sorry to see the same weaknesses, and recnet references which could have covered some shortcomings ignored. Less flashy than some, it should nevertheless have a place on the desk of every serious Internet user. copyright Robert M. Slade, 1993, 1995 BKINTPSP.RVW 950311.

The pace of change on the Internet is rapid, and ill-suited to the long lead times of book publishing. In addition, the volume and range of information on the net is staggering. Nevertheless, even the very brief "catalogues" found in introductory guides tend to be a lot of fun and serendipitously useful. This is fun. The "coke servers" are here, addresses for famous people, programming resources, UFO theorists, software utilities, government information and all the various and varied topics of the net. There are cartoons and graphics included; about two per page; which seem to take the place of the advertising in a regular yellow pages directory. (The authors are promoting "The Internet Complete Reference" (cf BKINCORF.RVW) less agressively in this edition.) This is useful. For Internet resource people, this is a lot faster than "grep"ing the active-groups and list-of-lists files when the persistent "What can you do on the Internet?" question pops up. The closest competition, "New Riders' Official Internet Yellow Pages" (cf BKNRYLPG.RVW) is more formal but actually contains fewer listings, and is not as likely to find information on what you are looking for. This needs work. The entries lean heavily on gopher entries and are light on mailing lists. The large format and 800 pages of listings look impressive until you see the amount of white space and number of cartoons. (The white space ("yellow" space?) *does* make the layout attractive and easy to read.) The subject categories could stand some input from a "real world" document such as a real yellow pages directory or the Sears list of subject headings. The index is vital, and needs the most work of all in order to make this a major reference work. The authors solicit comments and entries to catalog@rain.org. Certainly, any major net entity would be well advised to send them a note. Commercial information providers might even want to take out an ad to replace some of those cartoons.

I have to call a person who I am quite sure doesn't want to talk to me (regarding a legal matter). I called his 201 (northern NJ) number yesterday several times from my home (703) number and got "Your call cannot be completed as dialed." This was suspicious because I called him the day before and got through without problem. I verified the number from an old phone bill and then decided to try calling via my long distance carrier (LCI) calling card. This was successful and I finally got through (to his answering machine, unfortunately). I'm pretty sure he has Caller ID, but he may have some kind of call blocking in effect. Here are some specific questions: (1) How does call blocking work? That is, if the called phone was blocking the calling phone, would call blocking produce a "Your call cannot be completed as dialed" message? That seems like a pretty vague response, leading to frustrated callers like me. (2) Does Caller ID work across area codes? (3) If Caller ID works across area codes, what would the called phone display on an incoming call from a carrier's 800-number calling card? (4) Could this simply be the result of some network congestion condition? The default carrier is Sprint. (5) On the legal side, is there anything I can do to get this guy to answer his phone or at least return my messages? He has a legal obligation to do so and he's not meeting it. Lawyers don't help much; he doesn't even return his lawyer's calls. Thanks in advance, Scott Robohn robohns@bah.com [TELECOM Digest Editor's Note: I would investigate the discrepancy between your direct dialed call and the one you placed (direct?) via your long distance carrier. Call Blocking can work across state lines and area code boundaries. It works on the same basis as Caller-ID; either it gets through to you from a distant point or it does not. If the originating and receiving telcos are equipped to handle these new features then yes, you can call block someone clear across the country. An interesting thing to experiment with is attempting to block a number from some distant point. For example, pick a number in some area code in some distant location. It does not matter if you know who the number belongs to or not, or even if it is a working number. Notice how when you attempt to block a local number, the response is immediate. Either you blocked it or 'this feature cannot be used with the number you entered ...'. Now try your distant number. Notice how there usually will be no immediate response; your telco is making an inquiry at the distant end; in a way, it sort of resembles the unix command 'ping' where you 'ping' a distant location, or where you do 'finger @distant.site' and you may sit there a few seconds waiting for the network to deal with it. Eventually your telco will come back to you with a response saying either the number has been added to your directory of blocked numbers or that it cannot be added. And sometimes there is a *third reply* which is, 'that number cannot be added to your directory *right now* ... please try again later ...' which I take to mean your telco 'timed out' waiting for the distant central office to respond with particulars. There is one exchange in Chicago (312-855) which for the longest time -- maybe still, I have not tried lately -- would give Caller-ID but would not accept blocking. A whole bunch of it is used as DID numbers for a department store downtown. The Caller-ID returned bogus numbers on the exchange, and attempts to block anything there always got the 'cannot do it right now, try again later please' response. To answer your question about phrases, every blocked number I have ever encountered returned a message saying 'the party you are trying to reach has activated call screening, meaning they do not wish to accept telephone calls at this time.'. Note, they do not single you out; they just say calls are not being accepted. I have never heard it say 'call cannot be completed as dialed'. Maybe it was just a fluke when you tried it before. If you are still unable to dial direct, then try with various 10xxx codes. *They should fail also* since your local telco checks that out before passing the call. Then try via the carriers 800 numbers such as 800-CALL-ATT. If that works (just as your credit card attempt worked) then for some reason your local telco has managed to lose some information in its tables. Also, *which office* sent you the 'cannot be completed as dialed' message? Was it your local office or the distant one, or ...? Also bear in mind that maybe the identification is passed between telcos when dialing direct, but when you call via your long distance carrier it is not passed for some reason. Therefore he might indeed be blocking your calls but his office is not getting the message when the call comes via the long distance carrier. If that is happening, then for whatever reason your local telco is using the 'cannot be completed as dialed' message erroneously in my opinion. They should be using the 'has activated call screening' message instead. Regards does a person *have* to answer the phone, the answer is no they do not. Nor do they have to come to the door. I don't care if the sheriff is standing there with legal service, they do not have to come to the door and open it if they are inside their house. What the sheriff can do is sit on the front steps and wait for the person to enter or leave the premises then stick the papers in their hand as they walk past. Process servers know all sorts of tricky and legal ways to get that paper into your possession. If nothing else works, you -- not the sheriff, what does he care one way or the other ... you are the one with the beef -- you can go to a special court (in Chicago/Cook County it is called 'Chancery Court') and ask the judge to allow 'special remedies'. You tell the judge the fellow is playing games and dodging service. The judge will okay 'alias service' meaning you can tack the legal notice up on the wall in the courthouse and leave it there; also that you can send it by regular mail (we are assuming the deadbeat won't sign for registered mail brought by the post office) and as long as the mail 'sticks' -- that is, does not get returned undeliverable by the post office -- then service will be deemed to have occurred. But no, he doesn't have to answer the phone. You'd think he might be courteous enough however to put an outgoing message on his answering machine saying, "For your convenience, this line is answered 24 hours daily by this machine. You will never reach a live person at this number no matter when you call." For your convenience, of course ... or his, one of the two.

What is this? Just because the local telco CAN offer something at a cheaper rate this is unfair competition? I'm glad to disabuse you of the naive notion that someone buying 100 switches for 5,000,000 lines can get a cheaper rate from the switch vendors than an operator ordering one switch with 5,000 lines. > Let's look at the NYNEX voice mail example again.

You make an assumption that a more technically advanced and complex service is more costly to offer and should therefore be priced higher. That is an unwarranted, unsupported assumption that is proved wrong every day. As I pointed out above, not very many people want to recognize today that bulk purchasing DOES allow obtaining better prices from the vendors. You should see the battles our purchasing organization has with equipment vendors in trying to obtain the best possible prices we can get.There is nothing wrong with it. There is nothing illegal about it. There is nothing immoral about it. There is nothing unethical about it. There is nothing unfair about it. In essence, you are making the claim that the RBOC's can not possible do ANYTHING cheaper or better than competitors and that if they are offering ANY service cheaper than competitors it must be predatory, illegal, immoral, unethical, and unfair.

Sorry, you still haven't grasped the difference between unregulated/regulated and competitive/monopoly. A competitive service doesn't have to be the best EVERYWHERE. Sometimes PBX's are best, sometimes Centrex is. That is what makes it COMPETITIVE rather than monopoly. A monopoly service has NO competitors. You will find that unregulated service in the future will mostly be for those services considered as commodities. Lots of small competitors offering exactly the same service at about the same price. Regulated service will remain a fact of life for everything else for a long, long time. Just how many commodity type services do you think will come out of the telecommunications market in the next ten years? My opinion is very few. Local service/long distance vendors will be offering all kinds of integrated video, voice, and data services with numerous combinations and numerous pricing options. The state Public Utility Commissions are NOT going to let this degenerate into a "rip-off" market like the AOS's got into at the start of divestiture. > And, finally, I can't help but observe that your opinion of the > impracticality of my suggestion that RBOCs divest services as they become > competitive is practically word for word what many Bell System people said > 10 years ago when the breakup was announced.

Malarky. Required integration has nothing whatsoever to do with it at all. Would you prevent interLATA carriers from getting into local service? If not, then why would you want to prevent the RBOC's from being integrated as well? Would you prevent CAP's such as MFS from getting into the interLATA business? If not, then why would you want to prevent the RBOC's from doing so? BTW, the split between interLATA and local is NOT complete. Go look at the interLATA carriers hollering that their access charges are too high and that the local rates should be raised even higher. This has NOT been played out to it's conclusion yet, rather it is far from it. The regulators at all levels are going to catch a lot of heat over the next few years concerning just this subject. Unless you are willing to be consistent and say that NO company can be in more than one segment of the market at a time, then there is only one obvious conclusion as to why you would want the RBOC's broken up and prevented from being integrated competitors. > I'm under no illusion that the RBOCs are in any danger of being broken up > soon. Their lobbyists are much too good for that. But after a while people > may get tired of paying for services that they're not receiving and then > we'll see what happens. This is just one more groundless assertion. If the RBOC's can't compete, the market will point it out quickly. As market share is lost and investment becomes stranded, the breakup you so apparently want will happen anyway. On the other hand, if the RBOC's turn out to be strong competitors then arbitrary, capricious breakup by government mandate would be idiotic.

If after your written request is received by the evil sender and he/she continues to mercilessly harass you with unsolicited and unwanted faxes, you may seek legal remedies. I understand it is a civil matter and you must seek such remedies in a civil court, at your expense. An interesting point, however, is that if your business fax number is published in a directory or other public listing, then the law may interpret this as an invitation to receive faxes from anyone who reads the directory. If this is the case you may not have any recourse at all. Of course, there is always the waste paper basket, the shredder, the recycling bin ... [TELECOM Digest Editor's Note: But remember, the man's complaint was that fax paper costs money; he does not want to use so much of it. Maybe he could get a fax card for his computer and view the junk faxes on his screen *then* decide if he wants to print them out.

Voss <0002120410@mcimail.com> Subject: Re: Has There Been *Any* Digital Cellular Fraud Yet in the US? Pat: Regarding article about US digital cellular fraud, the response indicating that a "digital" phone had been compromised is not correct. In the US, there are still no "digital only" systems. Any digital cellular phone still uses an analog control channel, and the call is set up exactly the same as an analog call. This is when the MIN/ESN can be stolen off the air. When the IS-136 digital control channel is put in place (later this year in some systems), then it will be more difficult to steal numbers off the air. Then the call is really digital from start to finish, assuming you stay in cells equipped for digital. New PCS systems at 1.8 GHz will likely be all digital from day one. The PCS 1900 (similar to GSM in Europe) incorporates many features making cloning difficult. CDMA is also very robust.

GSM will be used in the US although it is going by the name PCS-1900. BellSouth, Pacific Bell, American Personal Communications, GO Communica- tions, and the Small Business PCS Association have all committed to build a PCS-1900 network. It also appears that Sprint will join in but that is only a rumor at this point.

(1-800-827-6364) Reply-To: gmnassar@aol.com (GMNassar) Local competition means being able to select your local carrier the way we are able to select long distance carriers, but the implications are much greater than this. In fact, in various states, the public utilities commissions "allow" providers other than the local RBOCs and independents to provide local service to residences and businesses if they wish. However, there are many obstacles that exist that hinder companies from entering this market. E.g., the cost to build the infrastructure that includes connectivity to all homes in a particular geographic area tends to be prohibitive. Therefore, an RBOC competitor would have to rely on the RBOC to allow use of its network for the "local loop" portion to carry a call from its source to its destination. Can you see the problems inherent in having to rely on your competitor to ultimately deliver services to one of your customers?! It is issues such as this that dergulation is addressing. It is complicated, and in my opinion must be done delicately and knowledgeably, or we will end up with a mess and no real competition for residents and businesses at the local level. [TELECOM Digest Editor's Note: Hey, an option is they can go out and string their own cable and build their own plant inside and out and come up with their own instruments, etc. After all, the 'real' phone company did all that. Granted, its been more than a century in the making; the telephone network in the USA did not happen overnight or even in a few years the way the competitors seem to feel it should. All the competition -- and that includes the long distance carriers -- seems to feel they should be able to jump on Bell's bandwagon and reap the results and rewards of a century of labor. I think the *only* thing the telcos should be required to do is provide interconnection on request in a fair way at arms-length. They should not have to sell anything to their competitors or provide them with anything. No local loop, no co-location in the central office, none of that stuff. You want to build a telephone company for local and/or long distance service? Fine ... go ahead. Build it however you want, sign up your customers, etc. I'd require the local telcos to be reasonable in number and prefix assignment to the newcomers, interconnect, and that's it. Period. After you have your central office built, your cables laid, your local loops ready to go and the other things that go into running a phone network then the local Bell people open the door and hand you a bunch of cable pairs for your interconnections. Now you sell phone service and they sell phone service. Is that so hard to under- stand? Yet we have these other outfits today who are no different than MCI was back in the early 1980's: they want only to skim the cream and drive the costs up for all other users while they get rich.

Like many successful net entities, it is more easily described by what it is not, than by what it is. This book is stated to be a companion volume to the "Internet Starter Kit for Macintosh" (cf. BKINTSKM.RVW). It is not, however, an extension or follow-up to the previous volume, which it is almost, but not quite completely, unlike. It isn't really a kit. Mac client software for archie, finger, WAIS and Gopher is included, but isn't really essential to the book. It isn't really for the Macintosh. The content has to do with people using the net, and the access method doesn't really matter. It is, in many senses, exploratory. The material does not demonstrate great expertise and is not complete. Chapter two, for example, deals with the search for people and email addresses, but doesn't even mention the MIT Usenet-addresses mail server. The book *is* very realistic about how to approach the net. The Internet "community" and "Try it, see what happens," feeling is there. It is not the usual Internet "beginner's guide". With chapters on searching for people, discussion, live chat, "stuff", resources and information, ejournals, and peace of mind, the closest comparison might be with Gilster's "Finding It On the Internet" (cf. BKFNDINT.RVW). Where Gilster's book is organized and thoroughly explanatory, this is a lengthy conversation between two witty netizens. It's sometimes hard to follow, but entertaining and well larded with tips, information and interesting points. "Dave", the editor, generally breaks in at the end of a chapter with a question or two, and the resulting summary is a concise, but generally cogent, analysis of the uses and pitfalls of the applications under discussion. (The authors also occasionally "dialogue" with non-interactive documents, such as Brad Templeton's "Ask Emily Postnews" network etiquette satire, or the whitehouse.gov presidential mailbots.) Those primarily interested in getting down to work on the Internet will find the organization and verbosity frustrating. Those who are interested in exploring, or playing with, the net will find a readable, funny, and friendly guide. copyright Robert M. Slade, 1995 BKINEXMC.RVW 950308.

Reply-To: mhuang@CapAccess.org Hi folks: I'm looking for the information on the ins and outs of a digital pager. I'm not in the telecommunications field so please use layman terms. Specifically I'd like to know when a person dials a number to send a phone number or message, how does the transmitter know which pager to send the message to? Aren't all pagers in a service area on the same frequency? I'd appreciate it very much any expert out there who could point me to the sources for detailed non-technical description. Mark Huang e-mail: mhuang@capaccess.org 2003 Stanley Ave. Rockville, MD 20851-2227 [TELECOM Digest Editor's Note: Yes, all the pagers of a given carrier are on the same frequency. The difference is in what some pager companies refer to as the 'cap code' of each unit. Imagine how in the old days everyone was on the same telephone party line. How did the operator indicate which party was to answer the call? Different ringing sequences and cadences were used and the human being on the other end was trained to respond only to (for example) two short and one long ring. Anyone who went off hook could listen; its just that you did not *know* there was conversation on the line or that you should be listening to it until you got that special sequence of rings. Now the paging company transmitter does much the same thing. A call comes in to the computer at the paging company. It looks at the DID (or identification number) of its subscriber which was entered, and says since the call came in on xxx-xxxx therefore it must be for John Smith, and the cap code (or little electronic chip in his pager) is zzzzz. So the first thing the transmitter does is send out the tones zzzzz or whatever to get your pager's attention. Now your pager is always 'listening'; it just does not respond until the transmitter sends out the desired tones in the order needed that your pager 'hears' them. It gets these little blips which mean for it to turn itself on and receive a message. If you were to remove the little bit of circuitry in your pager which detirmines what (on the airwaves) are for it and what are for someone else, then your pager would sit there receiving calls and messages from the transmitter all day long just like a scanner radio tuned to that frequency. If you have a scanner, you can demonstrate this to yourself. Note the frequency used by your pager, and set the scanner accordingly. Now put in a phone call to your pager and listen on the scanner. All of a sudden you'll hear the scanner go whoop! chirp! chirp! chirp! tweet! making tones. Then an instant later your pager will come to life, beep and display whatever was entered. Other pagers of other customers will remain silent because that sequence of chirps and beeps output by the transmitter were not for them. Let your scanner stay tuned to that frequency over a period of time and all you will ever hear, every few seconds or so are variations on whoop! chirp! chirp! chirp! beep! as one pager or another is told to turn itself on and receive a message. If you have a voice pager, those chirps sent out which match the 'cap code' in your pager serve to turn off the squelch letting you hear the transmission. Notice how if you do not press the button to shut off the voice pager and just let it sit there hissing dead air after your message is received, sooner or later it will start talking again when other customers get messages ... just like an old party line phone where once your call was finished you did not hang up the receiver, and presently you would hear others talking. If you decide to switch to a different beeper company, you take them your unit and they look at the cap code inside, then they tell *their* computer to tweak your unit whenever a call comes in. Or, they may open your unit and pull out that little chip and put one of their own in their instead giving you a different cap code, and of course they have to change the frequency your unit is on if they happen to be on a different one.

It is primarily focused on the US and Canadian arrangements, but other countries are not forgotten. Updated info or suggestions for further additions should be emailed to the above address. 1) What is a pager anyway? As usually described, a pager is a portable unit, generally about half the size of an audio cassette box, which can be signalled to send a one way message to the pager owner. 2) What types of messages? The earliest units, usually called beepers, simply gave a tone alert. This was a signal to the wearer to, for example, call the answering service. The next step was units which could display numbers. While the most common use is to send it the phone number you want the person to call, you can, of course, add code numbers to mean anything else you'd want. For example, the number xxx-yyyy-1 might mean to call the xxx-yyyy number at your leisure. Xxx-yyyy-9 might mean call ASAP. The most recent units, called alpha-numerics, display complete written messages. So, for example, the pager could show the message: "please call home, you have a letter from the IRS." There are also -voice- pagers which will let you actually speak into the phone and have it come out the person's pager. These are pretty rare. 3) How are messages sent to the pager? By radio. Well, it's a bit more complicated than that. Let's take a look at how a pager actually works: The pager is a small sized radio receiver which constantly monitors a specific radio frequency dedicated to pager use. It remains silent until it 'hears' a specific ID string which tells it to, in effect, turn on, and then listen up for, and display, the forthcoming message. (again that could be a numeric or other string) This ID is called (in the US) a CAPCODE. It has -nothing- to do with the phone number you call or the ID you give to the page operator (see below). So the key point is that the pager company radio transmitter is constantly sending out pages, and your specific unit will only activate when it hears its ID/CAPCODE over the air. 4) How do I send out the message? This depends on your pager vendor. Let's take the most common examples: a) Alert tone only (the old style) You call up a phone number assigned to the pager. You'll hear some ringing, then a signal tone. At that point you hang up. Shortly afterwards the pager transmitter will send out the individual unit's capcode and it will go off. b) Touch tone entry: You will call a phone number dedicated to the specific pager. It will ring, then you'll hear a signal tone. At that point you punch in, using touch tone, the number you want displayed on the pager. A few seconds later the transmitter will kick out the pager's capcode, followed by the numbers you punched in. Then the pager will give its annoying alert tone, the person will read it, and call you back. (note that there is a variation on this in which an entire group of pagers has the same phone number. You call it up, then punch in the pager's id number, and continue as above) c) alpha-numeric: With this one there are various ways of getting the message to the system. i) via an operator: The pager company will have you dial up their operator. When they answer, you give them the pager id number and the message. They'll type it into the computer and shortly afterwards the transmitter will send out the capcode and the message ii) using -your- computer: Most pager companies with alphanumeric have a dial-up number you can call yourself. Some of these will work with regular @comm programs, while others require proprietary software. The most common method is to have your computer dial up the number, then you type in the pager ID, followed by the message. Again, a moment later, the system will transmit it over the air, etc. (There are also various software packages that automate some of this) iii) special terminals: Because of the popularity of this type of system, there are various stand-alone terminals specifically designed for this purpose. The most common one is the @Alphamate (tm Motorola) and it automates many of the functions. It's basically a half-decent keyboard with a two line display, and is preprogrammed with the phone number of the company, etc. 5) My company has given us pagers, and I notice that I have both an individual ID and a "group" number. When we page out to the group, everyone's unit goes off. How does this work? Remember that a pager is basically a radio receiver that is constantly monitoring for its capcode. You can get pagers which monitor more than one id. In this case (which is quite common) your personal capcode might be yyyy, while your boss's might be yyzz. In addition, both pagers will be listening for the capcode zzzz. When zzzz is detected, all the pagers with that capcode will go off. 6) I keep hearing about sports or news services available by pager. How do they work? Keep in mind that pagers work by constantly monitoring the radio channel for their capcode. So if you have ten pagers, or a hundred, or a thousand, all with the same capcode, they will -all- go off at the same time. This way the sports news company sends out one message and it gets displayed by all subscribers. 7) So if I find one of these sports-news pagers on the sidewalk I can use it for free? Umm, kind of. As long as the company providing the service keeps using the same group code, your pager -will- continue to receive the messages. But the individual pager id will probably be changed immediately so you won't be able to use it for your personal messages. Note also that some pagers -do- have the ability to be turned into a lump of clay over the air. Very few systems have actually implemented this security feature, but it is there. 8) I've found a pager on the sidewalk and would like to use it. What can I do? Not much. Keep in mind that you need an account with the paging company for them to send out the radio signal. So unless you keep paying them, the pager will soon be a paperweight. You might as well turn it in for the reward... 9) Can I listen in/monitor pager channels? Kind of. The frequencies are readily known and the data is a digital stream going over the air. There are various vendors of equipment to decode the material and display it or feed it into your computer. However: a) The federales and the pager companies don't like you doing this (see the ECPA) b) The volume of traffic is quite high. If you figure a 1,200 baud channel in use 75% of the time, well, ... you can work out the math. Note that the numeric pagers these days do -NOT- use over-the-air touch tone (dtmf) so a touch tone decoder will -NOT- give you anything useful. 10) I have a pager for which I'm paying $big/month. I miss a -lot- of pages since I'm in the subway a lot. What can I do about this? There are a couple of things: a) Some of the pager companies will re-send messages on request. Basically you call up their phone number, punch in a security code, then go through a menu which tells them to resend the last, say, five hours worth of messages. b) You can get a second pager unit cloned identically to the first. leave this one at home or in your office. When you get back you can compare its messages to the one on your belt. 11) What are the prices/services offered? These vary dramatically by area and company. Unfortunately there is no central database keeping records on this. Generally the following factors get counted in determining what you'll be paying: a) how sleazy the company is; b) Which type of pager and service you get. Again, the most common are numeric (cheaper) and alpha-numeric (more expensive). c) Level of usage. You may get, say, 25 free messages/month and then pay $0.25 for each additional. d) whether you own the pager or lease it; e) insurance, etc. f) Area of coverage. Smaller area = less expensive. 12) Speaking of coverage, how do they offer nationwide paging? Well, it's not quite what they're telling you. It's NOT a single satellite covering the nation. Rather, what's done is: You call up the paging company. It then signals transmitters in the top 100 cities to send out your capcode. Shortly afterwards you get the message. Note that you are -not- receiving a satellite transmission. 13) What's in the pipeline? Two key features are slowly filtering down. a) Much more pager memory/longer messages. Most pagers are severely limited in the amount of material they can hold, with a typical maximum being about 20 messages. Units with much larger memories, or even better, units that are hooked into palmtop or laptop computers, are making it to market. b) two way communications: In its simplest form this allows the pager to verify reception to the transmitter. Also on the way is complete two-way communication which would basically be wireless email. These systems are still a bit limited, but are rapidly gaining footholds in industry and should soon be consumer level. Take a look, for example, at what the Fedex folk carry. Hope this help.

Others who wish to try this can submit their results here. PAT] USING AN UNREGISTERED CELLULAR PHONE: A FIRST HAND REPORT Not long ago I bought a cell phone for my car, and had it installed and signed up to a service as part of a package. This did not go well. When I showed up to pick up the car, the installers were still trying to get GTE to activate service. I drove off with a non-working phone and a promise. It turned out to take two more weeks of yelling at GTE to get it operational. It took three MONTHS to clean up the mess they made in hooking it up (GTE first claimed they lost the install order, then it later turned out they filed TWO of them and tried to charge me for another, inactive phone that I did not even know about). Anways, I am not here to discuss why NOT to sign up with GTE (although there are several really good reasons :) The major reason that I got the phone was for emergency use only. I figgured it was worth it as insurance against being stuck out in the middle of nowhere, and also to make urgent phone calls ("I can't come after all, my dog has been struck by lightning", etc.). After my I got my phone, my boss told me that his housemate also wanted to get an emergency cell phone, after being stuck on the freeway in a bad part of town. But he was annoyed at the idea of paying $300 a year for the minimum subscription price of the phone. He asked me if I had any ideas to get the cost down. I thought about it long and hard, and realized that the cost for an emergency phone could be $0.00, and I had already found out how to do this thanks to GTE incompetence. During the two weeks while I was waiting to use the phone, I of course played with it. What do you get if you dial out on an unsubscribed phone ? In California, you get "American Roaming Network", and they ask you for a credit card to place a call. It turns out that the basic thing that subscribing a phone gives you is the ability to call YOU. Without a provider and a number, there is nowhere to direct calls to you. Without a number, you look like a "roamer" from another service. And the system automatically connects you up to the "roaming service". Further, in California at least, dialing 911 still works. In fact, in california, it connects you directly to the highway patrol; the same folks you would get on a callbox on the freeway. After this worked for my boss, I dropped the service myself. First, about American Roaming Network. We found out the charge to use them is $2.00 an minute. However, that is flat rate no matter where you call in the USA (ie., the long distance is thrown in). Still, this is pretty high (Sprint charges .10 per hour anywhere). Also, my friend claims that he was charged $6.00 for a short call, leading us to beleive there may be a minimum three minute charge. What you are saving is that $300 a year can buy quite a few "panic" calls. Just make sure that you don't need to use it a lot. I have used American roamers a couple of times, and had few problems with it. They did not seem to be able to take my credit cards (two of which have been accepted everywhere else -- they seem to have a computer problem). Others claimed they had no problem with their taking a credit card. I was able to use the system with my ordinary phone card (if you don't have one of these, your phone company will send you one). I was able to use the automated part of the service for this, and even have the numbers on autodial keys on the phone. I had a chance to actually test the emergency use of the phone, because I forgot and ran out of gas. Now my AAA service is an 800 number. American Roamers does not take 800 numbers (I was not able to get anyone to tell me why, or even admit that it was so). I tried to talk an operator into using one of my cards to place the call, they were unable to do that, reporting that the numbers were invalid (even though I was able to use their automated service to place a non-800 call). I guess I wasted 15 minutes on that, just because I was trying to be a nice guy and not call 911. My next option was to call someone I knew and get them to call AAA for me, or dial 911. I dialed 911. 911 announced themselves as the highway patrol, and said they would call AAA for me, no problem. Should have done that first. All told, it did take another hour and another call to 911, but that was AAA's fault (1/2 hour average wait -- my ass !). I have also used the phone for "gosh I guess I'll be late" type calls. Boy does it feel slick to be in a traffic jam and call ahead to say you'll be late. But at $6.00 a pop, the amusement wears thin fast. All of this on an unregistered phone. Now I bought the phone on a package deal, and then just dropped the service after a month. It turns out this may be one of the best ways to get this done! So far I know two people who have walked in an tried to buy the phone unregistered. In California, it is illegal to require signup with a provider in order to buy a phone. But on the first try, our friend received such a hassle from the saleman about it that she walked out of the store. She was able to buy the phone elsewhere, however, without problem. In fact, she asked and found out that stores receive as much as $200 kickback from the providers for signing up each user! No wonder the salemen fight you about it! The bottom line is that if you live in a state that does not have the "no tie in" law, you probally will have to buy the phone used, or subscribe and drop, or buy across state lines, etc. If you live in a state that forbids tying, tell the store that and that you are willing to call the PUC. That should be enough. But it may not prevent them from charging you exhorbident "no hookup" charges. California, for example, has just struck down a limitation by the PUC against "tie in sales" offering a service/phone package (this is apparently not the same thing as the "no service required" law). This will increase the incentive of saleman to hassle you and/or give you "one year required" service contracts. All and all I think it is worth it. For $100 and less (I have seen phones selling, no service required, at Fry's local for $60), you get cheap insurance that will probally outlast your car. Buy the phone, keep it charged, throw it in the glove compartment or trunk, and forget it. There are also advantages to an unsubscribed phone. Since you don't have a number, nobody can "steal" your service number and make calls just because your phone is on. If you use a calling card (recommended), no one can listen in and charge snow tires on it. If you get a phone, you want a couple of things. First, the phone should have "online dialing". This means that the phone can transmit ordinary touch - tones (audio) while already connected. It should be able to store autodial buttons to do this. This is how you are able to enter your calling card number to the automated roamer service. Second, you want to be able to program the NAM (Number Assignment Module) for the phone. On my phone, I set the "system ID" to 00000, which is the same as it comes from the factory. It means "no service". One test you can do is to tell the seller that you want to test the phone in the store right out of the box. It should still be unsubscribed at that point. After hitting the "send" button (or whatever) you should be connected to American Roaming. Then you just buy it and leave the programming alone. If you get the programming wrong, it may say something like "incorrect subscriber ID". BUT IT WILL STILL CONNECT YOU TO American Roamers. In ALL cases we have found, no matter what happens, the error action of the system seems to be to connect to American Roamers. This is the default "error" mode. Is it "bad" that you can do this? Well, I called the 800 number for American Roamers, they had no problem with it (at the rates they charge they bloody well shouldn't). I even told GTE about it when they asked me why I was disconnecting. They just said "yea, that works". The biggest problem I ran into was the fact that the operators just did not seem to be able to deal with the idea that I did not have a provider. When telling me about why this or that card number did not work, they kept asking for my provider or recommending that I see my provider. Even the 911 operator did not seem to understand how I was able to make the call without being on a registered phone. The answer is simple. Just don't say anything, and use American Roamer's automatic service, which seems to be smarter than the operators anyways :) Good luck.

TTYs use Baudot protocol (no carrier, 45.5 baud). CCITT just approved Baudot (and a whole bunch of other international TTY carriers) as v.18 protocol. So ... if you buy a new Morotorol 28.8 v.34, for example, it comes with v.18 but *almost* all older modems that weren't specifically designed for the deaf cannot. This is a hardware thing, not a software one. Of course, if your friend has a TTY with ASCII (300bps, usually) protocol, then you can communicate, but most TTYs don't.

It works well. For whom? My sense is that it works for the relatively inefficient (and, until recently, mostly government-owned and -run) bureaucrats who administer the patchwork of European systems. Planning for future expansion appears to be unknown among these agencies. For consumers/customers/subscribers, knowing the number of digits to expect in a string aids retention in memory. An interesting sidenote is that early memory experiments have shown that the number of "chunks" of information (these can be digits) that we can readily retain in short term memory is remarkably close to the seven digits of most North American local phone numbers. If the number of digits WERE to be increased, I think it crucial that that increase be uniform across the country (better still, perhaps the world may one day be able to agree on a standardized number of digits).

Kimberlin <0004133373@mcimail.com> Subject: Early Benefits of Local Competition Local telephone competition's critics may be speaking as much from xenophobia as from real concerns. Two events during the past week in North Carolina indicate changes that would not be likely had local competition not been seriously underway. First, Southern Bell announced reductions of more than 50% in short-haul toll rates to areas surrounding Charlotte. That move was spurred after NC regulators permitted intraLATA toll competition from the interexchange carriers. Southern Bell still maintains a market advantage by denying the IXC's dialing parity. Calls dialed with only seven digits to adjacent areas route via Southern Bell, while users must steer calls via IXC's, dialing access codes, area code and number. One can readily see that most users will simply dial seven digits, while only businesses that study their costs will set up PBXes to insert digits if needed or route via direct IXC access trunks. Even though it's the users making a market choice, critics of local competition will still call this "cream skimming by the IXC's." But for how many decades have we been told that high intraLATA toll rates were essential to subsidize local base rates ... that if intraLATA toll rates simply could not be reduced without an instant increase in local base rates? Anybody out there remember? And now, that's no longer an issue as competition forces real action. Second, local television news told a surprisingly different story last evening about Southern Bell's new interest in trying to catch persons who place harassing or abusive telephone calls. In a statement totally the opposite of years of telephone company objections, Southern Bell added into a story about a string of harassing phone calls in Rockingham, NC to say it openly invites people who receive threatening phone calls to try to get someone on another line to call a special Southern Bell toll-free number, where the phoneco accepts calls from the general public to attempt instant traces on the source of such calls. (Before those who play the old hymns jump up with, "But it's so labor intensive," remember we are more than a decade out of the step and crossbar era in all but the most rural of localities.) Now, THAT's quite a change from the decades of first telling the public the phoneco would only trace calls for law enforcment agencies, then later telling users they had to initiate a written complaint and keep a logsheet of the calls, and most lately saying, "Just purchase Caller ID" so they could do it for themselves. Only now, after local competition is a _fait_accompli_ (effective in mid-1996 in NC), are the local phonecos spurred to provide an instant, open to the public means of assisting in catching telephone harassers and threateners. (Yes, it took a change, but it needn't have taken a decade or more to implement it.) It's rather certain that without the urging of local competition, changes like these would not have occurred. They point up that fears of "problems due to local competition" may be based more on fear of change than on any real problems. Within a week, local competition destroyed two shibboleths of phonecos in North Carolina. It will be interesting to see what other changes to the public advantage will result. Perhaps the old Chinese adage, "May you live in interesting times," is not always a curse. ------------------------------ From: daniels222@aol.com (DanielS222) Subject: My Computer Made Me Sick - Positive Ions Date: 16 Apr 1995 19:51:34 -0400 Organization: America Online, Inc. (1-800-827-6364) Reply-To: daniels222@aol.com (DanielS222) Hello Netters, On 2/14/95 CBS Evening News with Connie Chung, Dr. Bob Arnot did a story about negative ions and their effect on mood. They talked about a study done at Columbia University where exposure to a high density negative ion generator was as effective in treating winter depression as medication. I became very interested because I have suffered from depression and anxiety for years, and I did some research on the benefits of negative ions. This research turned out to be especially interesting to me because I found a newspaper article discussing the fact that computer monitors emit positive ions -- the opposite of negative ions. The article says computer monitors give off large amounts of positive ions and can actually cause depression, stress, fatigue, etc. in people who sit in front of computers a lot -- like all of us Netters -- and that we need negative ion replenishment. After reading the article, I realized that I always felt especially irritable, stressed, and depressed after long days in front of my computer. In doing the research, I found that negative ions have shown to be therapeutic for stress, irritability, fatigue, depression, etc. So I purchased a small, high density generator and it has given me substantial relief from my symptoms. If any of you would like me to e-mail you that newspaper article, the transcript of the CBS news story, as well as the other research that I have compiled, just e-mail me at DanielS222@aol.com. dan [TELECOM Digest Editor's Note: This is an interesting theory and worth pursuing.

Mitchell Kapor, Creator of Lotus-1-2-3, Co-founder of the Electronic Frontier Foundation ------------------------------- "Bacard's ruthlessly realistic but optimistic book explains the privacy dangers that YOU face and what YOU can do to protect yourself!" Jim Warren, Founder of "InfoWorld", Founder of Computer, Freedom and Privacy Conferences ------------------------------ April 1995, Berkeley, CA. Criminals, competitors (anyone, in fact) can buy a person's IRS forms for $500. An individual's medical records are available to complete strangers. TV star Rebecca Schaffer was shot to death by a computer stalker. These are just some of the horrifying examples of invasions of privacy that author Andre Bacard points out in his new book, "The Computer Privacy Handbook: A Practical Guide to E-Mail Encryption, Data Protection, and PGP Privacy Software." We live in the Age of Electronic Surveillance, Bacard says, and snooping happens. Given that millions of e-mail messages are exchanged daily, and the Internet buzzes with zillions of bites of online discussions each day, it's easy to see how this could be. But just as computers are part of the problem, they are also part of the solution. Bacard details how individuals can safeguard their electronic privacy using good encryption, proper data protection, and the right software. "Computer Privacy Handbook" shows how computers threaten YOUR personal security, and it gives YOU the practical tools to reassert YOUR privacy! In this book, find out: * Who is Selling Your Secrets * How Computers Help Snoops * The Dangers of a Cash-Free Society * How Big Brother Wants to Monitor ALL Telecommunications * Why E-Mail Can Be Terribly Unsafe * What to do with Your Social Security Number * The Advantages of Anonymous Remailers * How to Protect Yourself with Encryption * The Best Usenet News Groups for You to Visit * Where to Find Expert Privacy Activists "Computer Privacy Handbook" also contains a user-friendly manual for PGP software. PGP ("Pretty Good Privacy") is a top-rate program to protect your personal and business data files and e-mail from snoops! PGP is the de facto world standard for e-mail privacy. Author Andre Bacard, who also wrote "Hunger for Power: Who Rules the World and How," has a wide-angle view of society. He has written about technology and society for numerous publications.

In these days of small area codes, they would help even more, since knowing a full "name" would help remember the associated a.c. with it. For example, in the Philadelphia area, we have MItchell in Ambler, which is 215, and MIdway in Ardmore, which is now the new 610. If someone threw at me "646-xxxx", I wouldn't know which area--I don't know which 64x's are in Admore or Ambler. But MItchel and MIdway are easy to remember and where located. There's a lot of examples -- LOcust in downtown Phila (215) and LOwell in the suburban town of Media (610.) When Bell introduced 610 it printed up exchange lists -- hundreds of tiny three digit numbers, impossible to remember. However, if they still used exchange names, the list would be a lot smaller and easier to remember. I know not all exchange combinations can create an English word. But using exchange names doesn't call anybody anything. And considering how intensely 800 numbers are using letters for their names, I fail to see why the traditional exchange names can't be brought back. P.S. In Phila, many exchanges were logical names. For example, the City Hall centrex is MUncipal (it's now 686 and 687)*. MAyfair, CHestnuthill, GErmantown, SHerwood, MElrose, BAring all refer to their respective neighborhoods. In New Jersey, a lot of exchanges were named for the towns. -------------------- *Philadelphia libraries still use original rotary phones that retain the MUnicipal 6 number card. The system is slowly being modernized as funds are available. ------------------------------ From: relkay01@solix.fiu.edu (ronell elkayam) Subject: Please HELP With LD Caller ID Experiment Date: 16 Apr 1995 00:22:19 GMT Organization: Florida International University All I'm asking for is that some nice guy (or girl) will spend a couple of minutes helping me compile a list of all the Long Distance carriers that currently allow Caller ID information to be sent over state lines. This experiment would prove useful for thousands of phone users all around the nation. The problem that caused the need for this experiment is the refusal of the LD carriers to comply with the FCC ruling for them to provide CID information to the local phone co. from the date 4/12/95. They complain that it cost them money to send the info, and so they now plan to argue their case against the legality of the FCC order (which was postponed not too long ago by the FCC itself). However, not all LD carriers are such bastards. It's been shown that some, such at WilTel (10-555-1-xxx-yyyy), _do_ send the CID info to the local telco's; and so I am in search of which LD carriers these are. The way to do this is simple: please leave me email and we'll set a meeting channel on IRC where we both can meet and start scanning the LD carriers. The way to do that is easy: You will tell me: "Ron, I'm calling you right now on the other line with 10288 (AT&T). Tell me what your CID shows." I'll then look at the CID on my other line and tell you if it shows "Out of area" or your number (you will already have _my_ number as you call me...) The call MIGHT be billed for one minute of usage, according to bjg@bgfax.com (B.J. Guillot), so if you'd rather me calling you instead -- no problem. Obviously, you must have Caller ID enabled on your line. The calls shouldn't cost more than 20 cents a pop anyway ... I hope to repeat this experiment with as many people as possible in as many different locations around the nation as possible in order to create the most detailed and precise list of LD carriers as possible. Again, if you have Caller ID (and two lines) and would like me to call you instead of you calling me -- just say so; it's no problem. Either way is fine with me. Let's get together and start experimenting. Thank you very much for reading. Hope to receive your email soon. Ron ------------------------------ From: turner7@pacsibm.org (Lee Winson) Subject: "Message Unit" Charging Date: 17 Apr 1995 12:08:36 GMT Organization: PACS IBM SIG BBS In Philadelphia, Bell retains the old message unit charging system for short haul calls. I was wondering if other locations use this system. The way it works, in brief, is this: There are call "bands" extending outward from your home exchange (every exchange district has its own set of bands). Bands range from one to six, which is the number of message units for a call. Calls of one unit are UNTIMED. For Philadelphia residents, the entire city is within band one, and for people who live at the borders, adjacent suburban communities are also band one. Bands two through six are timed. In your bill, you do NOT see itemized calls, but rather an accumulation of message units. Note -- the system has been slightly revised to be "measured service", with some features, such as different costs per time-of-day, but is basically the same. Depending on your class of service, you get an allotment of units. You can also get "Metropolitan" service which gives unlimited calling. The Phila area has a defined "Metropolitan Calling Area" which includes the city and nearby suburbs. Message Unit calling is for this area. Calls beyond this area are itemized toll. For people outside the metro area, all calls other than local are toll. Local calls are the equivalent of one unit, untimed.

Wait a minute. NYNEX's service is a thoroughly MEDIOCRE service but it KILLED the competitive voicemail market? Sounds to me like there wasn't much of a market to begin with. You are trying to make it into a killing of a major market but then describe the market as almost non-existant. You can't have it both ways, you know. > There are all sorts of features that I'd like from a voicemail system: > forwarding among mailboxes, outdialing to other phones or pagers, delivery > as a voice attachment to e-mail, stuff like that.

John, you still haven't shown me that you know how stutter dial tone is provided. As a clue, you need a system that is connected to the central office switch using a "input/output" link. In essence, the voice mail system becomes an extension of the central office with messaging being passed between the two systems. It is this messaging link that allows messages to be passed to the central office switch from the voice mail system to condition the switch to return stutter dial tone. Input/output channels are expensive to provide in central offices. This causes a high price to be put on them. This may be why no voice mail services have purchased such an arrangement. The voice mail providers would have to provide for one of these links for every central office in which they have subscribers. Quite expensive. So, assuming that most voice mail providers are not going to buy such an expensive arrangement just to get dial tone, this leaves only CFBDA as the service in question. I know that NYNEX provides a routine for customers to order "special service arrangements" for non-tariffed services. Have none of the voice mail competitors gone this route to get a fully cost justified quote for the cost of getting CFBDA from NYNEX? This is usually the first step in getting the RBOC to tariff a service. If the RBOC refuses to provide a cost quote on a legitimate request, the utility commissions usually become very agitated. Especially when the RBOC is already using the feature. Oh, but I forgot, this is a grand conspiracy between the RBOC and the PUC, right? Nothing would come of these complaints, would they? > I suppose in the long run there'll eventually be dialtone competition, so > I'll be able to consider availability of decent voice mail as one component > in choosing a telco, and ditch NYNEX.

Right now, though, telco > eagerness to move into new markets and regulatory willingness to let them > do it in a way that stomps the competition combine to produce extremely bad > public policy. "Stomps the competition". Still with the emotional appeals rather than real arguments, eh? If there is so much money to be made in this if the RBOC would just play fair, why don't YOU coordinate a start up venture in Ithaca? You should have no problem convincing the PUC that the RBOC isn't playing fair and may even convince them to impose punative damages for you. Oh, I forgot. The RBOC and PUC are in cahoots on this - the PUC wouldn't listen to you. Once again, your argument boils down to nothing more than proposing that the RBOC's be disbanded, their employees put on the streets, and the customers the competitors don't want be handed to a nationalized government telephone bureaucracy for service. It just doesn't fly no matter how hard the wings flap. > Haven't been able to pull the SWB and SBC 10-K's yet to compare > profitability, since I've been on the road, will do that tomorrow. No rush. I really don't think you are going to find much real evidence that illegal activities are going on. Too many others have already done scrutinized them for just such evidence.

Date: Sun, 16 Apr 1995 18:43:51 GMT I just began using an AT&T 6650 pocket-sized cellular telephone. This is a dual-mode unit, compatible with TDMA (digital) and AMPS (analog) service in North America. In wandering around its extensive nested menus, I came upon the FIELD TEST MODE option. This one is not explained in the Owner's Manual. When I enable this mode, the display shows a continuously-updated array of fields like this: -093 0 3 0331 - 0 IDLE When the alpha mode (the ABC button) is turned on with FIELD TEST MODE enabled, the display is replaced by: rrrr s d ccccc l a CS-state The alpha-mode appears to be a set of labels for the data displayed in normal mode. It would appear that the rrrr field is the RSSI or received signal strength value. It varies as I move the unit, extend/retract its antenna, or shield it. The cccc field appears to be the current radio channel. CS-state appears to be the current operating mode. Can anybody tell me what the s, d, l, and a fields indicate?

Allen) Here is a press release from Volunteers in Technical Assistance (VITA). I downloaded the press release from the U.S. Newswire BBS in Maryland at 410-363-0834. I do not work for VITA. VITAsat Gateway Licensed in South Africa To: National and International desks, Communications Writer Contact: Joe Sedlak of Volunteers in Technical Assistance, 703-276-1800 ARLINGTON, Va., April 13 -- Henry R. Norman, president of Volunteers in Technical Assistance (VITA), announced today that the University of Cape Town, South Africa, received its license to install, operate and maintain a VITAsat Gateway Satellite Station. The letter from the Postmaster General of South Africa states that the gateway is to transfer messages from satellite earth station users and VITA in the United States. "This is an important milestone in our VITAsat program. We will use the Gateway to transfer messages directly to the Internet host located at the University of Cape Town. This will dramatically speed up the transfer of messages to and from Africa," said Norman. He added that other gateways are planned for Norway, Chile, Australia and Ireland. VITASAT-A is also the first satellite in the GEMnet system of CTA Inc. of Rockville, Md. The satellite was constructed by CTA and will be launched by Lockheed within the next couple of months. CTA also designed the new earth stations, including the gateway stations. VITA will use the satellite for development and humanitarian communications; CTA will use the satellite for commercial purposes. "Our goal is to help develop a communications infrastructure in developing countries. Most people in the world have no access to phones, and even a modest goal of providing one phone per 100 residents is pretty far down the road in some countries." Norman added that "When we became involved in communications, the Internet wasn't available to the general public. Our gateway system will extend Internet everywhere in the world." He continued, "We are delighted to be partners with the University of Cape Town. We expect them to play a significant role in the evolution of the system that will help close the information gap separating developing from developed countries." The person responsible for the Gateway at the University of Cape Town is Dr. Robin Braun, director of Digital Radio Communications Research Group. VITA first began experimenting with low earth orbiting satellites in 1984 when the Digital Communications Experiment was launched in UoSat-2. In 1990, the prototype payload was launched in UoSat-3; both satellites were constructed by Surrey Satellite Technology in Guilford, England. The Federal Communications Commission granted VITA Pioneer's Preference Award for being the first to use low earth orbiting satellites for civilian purposes. This award assures VITA of an operational license within the United States. -------------------------- Nigel Allen, Toronto, Ontario, Canada ndallen@io.org Web page: http://www.io.org/~ndallen ------------------------------ From: teddo@gwis2.circ.gwu.edu (Edmund T. Baumgartner) Subject: Telecomm Industry in Japan Date: 16 Apr 1995 18:44:28 GMT Organization: The George Washington University, Washington DC I am writing a paper on the deregulation of the telecommunications industry in Japan. My paper looks at the effect of a recently passed administrative law -- the Administrative Procedures Act (APA Gyosei Tetsuzuki Ho) on regulation by the Ministry of Posts and Telecommunica- tions of Type I and II Carriers under the Telecommunications Business Law (TBL, Denki Tsushin Jigyo Ho). The APA should make it harder for the bureaucrats to get companies in Japan to "comply" with informal requests, directions, etc. not to cut rates, provide new services and the like. I would be interested in hearing any stories people have heard about the Japanese government's regulation of the industry.

If it is, it doesn't achieve it! Apart from the five cities named, the code change doesn't create ANY new numbers in the UK. It does create about 750 new codes -- but short of a major series of area code splits or similar techniques, we won't be able to make any great use of these. Don Cruickshank, the UK Director-General of Telecommunications, accepts that key English cities are now rapidly running out of numbers, and has given an assurance us that there will be a full and open consultation later this year on how to resolve this problem. There are several possible solutions, with varying details, but every solution can be analysed down to one of three basic strategies: either we have more than one code for a city area (i.e. overlay -- which is anticompetitive where there is competition for local dialtone, and which to avoid misdialling would probably require users at that location to adopt a "full national number dialling" approach) or we expand the local numbering scheme to seven digits (or, in the case of London, eight digits). A third option is the traditional NPA split where half the numbers get a new code: but both the last two options would necessitate users having to change their numbers again. Yet on GMTV (our independant early morning station) on Thursday this week, Cruickshank specifically stated that from Easter Sunday 1995, anyone with an 01 number in the UK would be able to keep it and would NOT have to change it again. Fortunately I have a transcript from the videotape! So -- was he being economical with the truth about 01 numbers not having to change again, or has he pre-decided one of the fundamental issues of the proposed consultation -- thus rendering the *actual* consultation no more than window-dressing? Users in the UK are asking for an answer. > I remember reading/hearing that there was a plan to change all numbers > in the UK to a uniform length of 10 digits, but I could be wrong. This is indeed correct. Apart from the changes I have detailed above, about 200 more locations still have to undergo an extra change, to bring their number "up to standard" as the BT network is modernised.

Once every four or five calls, the phone will stop sending my voice (I can still hear the other party). This happens regardless of which phone is attached to the third extension, even an old and reliable Bell System phone. We do not experience this problem on the other two extensions. I am not absolutely sure, but I think this may happen only for long distance calls. A US West technician thought it might be a "grounding" phenomena, but was unable to remedy the problem. Intermittent problems are always the most difficult to isolate. Given the telco expertise present on your news group, I thought you or someone else might be able to suggest the source of the problem. Please feel free to post this e-mail -- For reasons unknown to me, my news server will not let me make postings at the moment. Sincerely, Charles Mott (using my father's e-mail account, jackm@pmafire.inel.gov) [TELECOM Digest Editor's Note: Interesting you mention it. I have a phone with an old handset cord which does the same thing once every four or five calls ... or did until I finally replaced the cord and repaired the place where it connects into the receiver. In the past this same problem would occur and when I would tweak the cord a little with my fingers the problem would go away and we could hear each other fine. That 'grounding' the tech discussed might well be in some of the wiring between the phone jack for that extension and whereever it meets up at the demarc. You might look and see if there is a tiny bit of bad wire. Next time the problem occurs, try and go along the wire tweaking and pinching here and there. It could be some little place in the wire is slightly exposed; not enough to consistently cause problems but enough to occassionally do so. If you find such a spot in the wire then deliberatly test it and try to recreate the situation where your voice cannot be heard on the other end, etc. That is one possibility; there are others. Perhaps more readers will respond.

Steve Geimann, Senior Editor Washington WASHINGTON -- GTE and Dept. of Justice are deadlocked on lifting 1984 consent decree that limited company's local companies from providing long distance services. Last week, the company asked U.S. Dist. Judge Harold Greene in Washington to remove the decree, saying sale of Sprint and Spacenet, whose original acquisition prompted impostion of restrictions, removed all legal reasons for continuing the decree. GTE said it planned to resell long distance through LECs, offer advanced services to other carriers, combine IXC and international functions in Hawaii and offer credit card for services -- when the decree is lifted. Justice Department officials didn't comment on GTE motion, reserving comment until June 5 deadline for responding in court papers. But in memorandum accompanying motion, GTE accused the government of "retroactively" seeking AT&T-like restrictions to block its effort to lift decree. Company said government opposed lifting decree because "it now serves to address other competitive concerns" regarding GTE local companies offering long distance. GTE demanded Greene force Dept. of Justice to issue a statement rather than accept "veiled or later invoked state- of-mind" by government. Decree required GTE's LECs to: (1) Avoid providing interexchange services. (2) Remain separate from Sprint and Spacenet. (3) Provide non-discriminatory equal access to all IXCs. (4) Maintain information services as separate subsidiary. GTE now resembles company as it existed before Sprint-Spacenet acquisition, company said, and decree wasn't necessary. GTE said Dept. of Justice appears to be keeping "the decree alive with extraordinary life-support arguments ... It appears that the government will now attempt, retrospectively, to transform this case into the AT&T case -- even though the government previously took great pains to distinguish this acquisition case from the AT&T conduct case." GTE said "revisionist approach" stems from worries that GTE will violate Sherman Antitrust Act rather than only Clayton Act, which decree covered. Company said government didn't pursue Sherman action "presumably because it could not in good faith do so." GTE said government now seeks to establish decree was "agreement" that could be used to create additional restrictions, especially in providing interexchange services. To succeed, GTE said, government must establish that GTE "agreed to be bound" regardless of its Sprint ownership. In addition, Dept. of Justice must prove courts can enforce consent decree when cause has been removed "based merely on the parties' agreement and on an assertion that the decree's provisions serve other, allegedly beneficial, goals of the government." ------------------------------ From: sayre@CS.SunySB.EDU (Johannes Sayre) Subject: What to Use to Connect Home Network Doing X? Date: 18 Apr 1995 03:33:49 GMT Organization: State University of New York, Stony Brook (guest) I'm looking at how to put together a couple of systems for working from home, and I'm looking for advice on what to use to connect them. [It will be obvious that this is new to me, so thanks for your patience...] I need two systems (for two people) both running a windowing environment, each with six to eight X terminal-emulator sessions up concurrently, little other local work going on. The systems will either run a unix, or Windows/PC stuff. I will go out over SLIP to a provider. It's a local phone call to the provider. The X apps will mostly be running locally, the traffic out to the provider will be rlogin & telnet (i.e. little X traffic). I'd _like_ to have one SLIP line out, and use one machine both as an active workstation, and as a gateway out for traffic from the other machine. Like so: --------- L ---------- SLIP (28.8 ?) | w/s W |-----------| gate G |----------------------|| telco --------- ---------- 1. Is it feasible to feed traffic from two workstations doing this kind of work out over one SLIP link, even at 28.8 ? Or will it be so slow that I need a line per machine, period ? If I _can_ gateway out over one SLIP line, then my next question is 2. What should link 'L' be ? - ethernet ? do I need that speed to support the traffic from 'W' ? Or can I do - SLIP ? even if I have the bottleneck of SLIP going out to the provider, would it still be helpful to have ethernet speeds on 'L' to make that part of the setup less constrained ? - something else ? what ? I don't anticipate a lot of X traffic over 'L', but it may happen with higher frequency than over the line to the provider. 3. I assume that commercial null modems would be sufficient to support SLIP on L ? Do I need intelligent serial boards, or are built-in serial ports generally sufficient ? 4. Am I going to develop sleeping sickness if the gateway is anything less than a Pentium or small RISC ? Will I develop sleeping sickness even if it is one ? (seriously, is that class of machine up to the load this setup would put on it ? Can I get away with less ?) 5. Can I get away with a cheapo box for 'W' ? Or if I end up packing its traffic out over SLIP, should I make sure that at least the machine isn't a hindrance ? Tangent: it occurred to me that 'W' might be an X-station. That means 'G' would need to be a fairly fat machine supporting emulators for both workstations plus handling the networking ? (again, is a Pentium- class machine necessary/sufficient ?) If I do this, should 'L' be ethernet ? Finally, is all this worth the expense? (yeah, it's fun) Or would it be cheaper to just go with a separate line for each workstation? I'm doing this primarily because of job demands, not pleasure ... I will appreciate any and all comments, suggestions, advice anyone may have on the above. If you have a setup to suggest that is radically different, please let me know about it. You will earn my eternal gratitude :) Sorry if I haven't done some piece of homework; I'm just learning where to look. Email or replies to the Digest are fine.

Date: Mon, 17 Apr 1995 16:51:04 -0400 Organization: MRJ, Inc./Oakton, Virginia, USA Our company has about 50 analog telephone lines that we use for fax machines, modems, etc. of which I use 16 for dial in terminal service. Although we purchased some good quality MultiTech modems, more than 50% of the people dialing can't sync up and get a carrier on the first call. Some days are worse than others. Our company telecom guy says that there is a lot of noise on the line coming from the CO, even when the phone is on-hook. Several weeks ago we were discussing future expansion requirements and I mentioned the line quality problem. (I am planning to install v.34 modems in the next fiscal year and would like them to be "useful.") One thought was that if we eliminated the last *analog* mile from the connection, we would get better quality for our dial-in pool. We can purchase a T1 card for our telephone switch and get 25(?) phone lines that way. Would we get better quality service with a digital connection to the CO? In the long run, it is *cheaper* to run our modems and fax machines through T1 card's but the break even point is +3 years (includes the capital investment of the T1 cards for the telephone switch).

Cloos Jr.) Subject: Integrated POPs Date: 17 Apr 1995 10:29:13 GMT Organization: Illuminati Online What are the current solutions for going from a T-1 (or preferable a T-3) of DS0s to Ethernet in one box? I'm aware of the Ascend Max and USR Total Control products for a pair of T-1s. Are there any other T-1 solutions? How aobut T-3? The list price for the latest Max offering from Ascend (as per their press release, for 48 lines) is nearly four times the per-DS0 cost of separate pairs ==> discreet (Sportster) modems ==> an Annex 4000 ... Even considering USR's Courier rather than the Sportsters, the price ratio is nearly 2. (Both examples are equipment only, ignoring LEC charges.) TIA, James H.

They would be able to get the information they need by using a touch tone phone, and get the fax they required by punching in their fax number; just like other voice response unit in some large companies. I prefer not to purchase such system as I would not have the time to configure/maintain such system. Would there be such service provider?
