Mitnick had managed to evade authorities in both Los Angeles and Seattle during the past two years. He was caught through the efforts of one of his latest victims, computer security specialist Tsutomu Shimomura of the San Diego Supercomputer Center. Shimomura was robbed of security programs he had written when his computer was broken into on Christmas Day, about two months ago. But one thing Mitnick apparently had not forseen was that the programs he stole -- and then used -- would be used to help track him down. Shimomura was able to detirmine this past weekend that Mitnick, 31, was connecting through a modem attached to a cellular phone somewhere near Raleigh. Through the cooperation of telcos and cellular companies, authorities were able to track Mitnick to his home early Wednesday morning. Authorities say they hope this latest arrest brings to an end the career of a man who began hacking and phreaking when he was in high school. At one point Mitnick broke into a North American Air Defense Command computer in Colorado. Referring to Mitnick as a 'dangerous computer terrorist', Justice Department spokesman John Russell said the raid was conducted at 1:30 am on the apartment in Raleigh in which Mitnick was living alone under a false name. "His obsession was his downfall," said Deputy United States Marshall Kathy Cunningham in Los Angeles. "His obsession to hack and phreak using cloned cellular phones left us a good trail to follow." Mitnick, who is known by the hacker name 'Condor' says he took that alias after seeing the movie 'Three Days of the Condor' starring Robert Redford as a man on the run from the government. He grew up in Los Angeles, and was convicted there in 1988 after a series of phreaking and hacking incidents which included disconnecting the phone service to Hollywood stars and others. Although initially he was given just a short prison term followed by federal probation, he continued to act out in his self-destructive ways and when his probation officer threatened to revoke his probation and send him to prison, he disconnected her telephone to get even and then ran off! And he is supposed to be a smart guy? In 1989, federal prosecutors in Los Angeles portrayed Mitnick as a brilliant young man 'obsessed with junk food and computers' who infiltrated computer networks and telephone switching systems in the United States and England. Although federal authorities suggested that he had broken into National Security Agency computers, he was never charged with that crime. At one point however, they considered him so dangerous they got a judicial order denying him any use of telephones at all, for fear he would call up a computer and access it using the touchtone buttons on the phone. In the earlier 1988 case, Mitnick agreed to plead guilty to hacking the Digital Equipment Corporation (DEC) computer network and stealing a program. He also pleded guilty to theft of sixteen MCI long distance access codes and using them to make long distance calls. For this, the court's imposition of punishment included several years imprisonment with all but one year suspended, to be followed by federal probation for the remainder of his term. After release from prison, Mitnick began his probation. When his probation officer suggested she would revoke his probation because of his behavior and return him to the penitentiary, his response was to hack the appropriate computer and disconnect her phone service ... he then fled. In the fall of 1992, Mitnick was working for a private investigative firm in Calabasas, California when the FBI was conducting an investigation into the break-ins of Pacific Bell computers. Realizing they were about to close in on him, he fled again ... to surface only yesterday when a man he decided to trifle with -- Tsutomu Shimomura -- decided not to get mad, but instead to get even! Shimomura cooperated very closely with the government to pinpoint Mitnick's whereabouts. On Wednesday, February 15, 1995, Mitnick was taken before a Magistrate in Raleigh, North Carolina where he was arraigned on the charge of violating the terms of his probation in 1988, and new charges of computer fraud in North Carolina. Assistant United States Attorney David Schindler in Los Angeles said additional charges pertaining to Mitnick's actions in San Diego, Seattle and Colorado would also be presented. Citing its belief Mitnick was a danger to the community and likely to flee again if released, the court ordered him held without bail, and once again restricted his unsupervised use of telephones. Mitnick may be a smart man, but he seems to lack some common sense. One does not ever screw around with one's federal probation officer; you don't play with her telephone to get even; you don't run off when she calls you. And when you are on the lam or otherwise, you don't steal from someone like Tsutomu Shimomura. Speaking of whom, Shimomura attended the proceedings in Raleigh on Wednesday. At the end of the hearing as he was being led away, a handcuffed and shackled Mitnick turned to Shimomura, whom he has never met or seen before and said, "Hello, Tsutomu, I respect your skills." Shimomura nodded, then turned his back and walked away. It must be remembered that in the United States, our constitution requires a presumption of innocence on the part of Kevin Mitnick until his guilt is proven to the satisfation of a judge or jury in a court of law.

Date: 16 Feb 1995 17:38:49 GMT Organization: University of Pennsylvania Having just gotten a new cordless phone (BellSouth 46mHz), and living in the paranoid environs of Washington, DC, I find myself wondering just how likely it is that the world is listening to my calls. The phone has ten channels, and a security code feature which, so far as I understand, exists mainly to prevent another cordless handset from tapping into my base unit, but does nothing to scramble the signal from the handset. I live in an apartment building, with a few others nearby, so consider this a high-density area. Should I go on the assumption that people are always listening in? Sometimes? Almost never? I have a corded set that I keep hooked up for confidential calls; as a stopgap, I sometimes scan channels on my cordless so any eavesdropper will at least have to fiddle to find me again. Does this help, or am I kidding myself? Thanks, Jeff [TELECOM Digest Editor's Note: Corded or cordless, the assumption should be that your telephone calls are never secure. In actual practice, it may not matter to you; if you are just in idle chatter with someone you aren't going to bother with the trouble of special precautions. My personal belief is the use of scanners to listen to cordless phones is still a relatively rare thing; how many people do *you* know that own scanners who are within range of your cordless phone? And of those, how many are sophisticated enough to know how to program the scanner for cordless? So my feeling is generally its not a big deal, and if you do have something very important and personal to say, you might want to go to a payphone anyway.

I observed that some trivia notes were also included regarding NPA assignments. I wanted to make you aware of another example pertaining to Port Roberts, Washington. Point Roberts is a six square mile section of land located on a penisula south of Vancouver, Canada. The Point is in the United States because the portion is south of the 49th. For many years, the local prefix 946 was assigned to the 604 area code and local coin phones were desinged to accept Canadian currency. Sometime in the early 1980s, the 946 prefix was reassigned to the 206 area. I have not been there since, so I cannot offer an update if the coin phones were transfered to accept US currency. I thought you would enjoy this. My friend asked that I reference his homepage for your reference. http://www.america.net/~mikef/mikef.html [TELECOM Digest Editor's Note: The last I heard, which was some time ago, 604-946 and 206-946 both got you the same thing in Point Roberts. I think directory assistance via 206 or 604 were both available also. Did you know it is impossible to travel from Point Roberts to anywhere else in the United States by automobile without going through Canada? School kids there go to school 'around the bend' in a nearby area in Washington State, but to do so, their school bus has to enter Canada, drive a few miles east, then drive back into the USA again, the same as anyone else wanting to drive to the next (USA) town over.

After my original posting I received about 14 responses, most of which had similar horror stories to tell about MCI billing problems. As I mentioned previously, the bill was paid in full by credit card in January. This week (of 2/5), we had a phone call from MCI where we were told we had not paid our bill -- I interrupted and told the woman, "Yes, we had, by credit card." "We already have the credit card billing with the MCI payment on it" -- the exact amount she was saying we still owed! She hesitated a moment, and then said, oh yes, I see it now! Makes one wonder just how complicated a form she is looking at, and what is wrong with their programmers if such a field is not checked before the bill is flagged as not paid! In addition, yesterday, Feb. 9, we received notice in the mail warning us that our bill would go to a collection agency if we did not pay. [This is the second mail from MCI in the past week -- we did receive a listing of calls made, though it did not appear to be a bill -- my guess is that this resulted from an emailing to an MCI employee whose address I pulled off of a news group, and who faxed the original posting to MCI's Consumer Executive Customer Relations (Residential).] In any case, my wife called this time. She got ahold of a woman and explained the situation to her. But no, the woman said, her records did not show we had paid. She, in turn, called another office, who then told her, yes, we had paid! The woman assured my wife that the problem would be cleared up. We are not holding our breath. And the second update. We received a nice letter of apology from MCI's Denver office yesterday (2/14), along with a $25 check for local or MCI phone service! Unfortunately, also yesterday, two MCI bills arrived, both for the same exact amount we paid by credit card in January. And sure enough, one bill was to our old address (old by five years) -- the Post Office evidently caught it and delivered to our current address. My wife, glutton for punishment that she is, called the MCI number listed on the bills. Again, it was not clear to the woman she talked to that we had paid the bill. The MCI employee did say our account was being transferred. This did jive with what was stated in the apology -- that U.S. West had sold out their rural service (we have a cabin) to PTI, and that this had happened last October (fits month problem started), and then (MCI) had made a series of errors that we had been experiencing. It is interesting that MCI thinks they are transferring our service, since we terminated their service after paying the bill. The woman said she was going to flag our account so that we would not keep getting mail and phone calls (where have I heard that before). This situation must be an example of the notorious "corner case".

I have always been amazed at the complexity of ratemaking. Looking from high above, the local access part of a long distance call is a local business call, and should be billed as such by the LEC. (Strictly speaking, if the call originates from a residence, the originating access segment is a local residential call.) Of course, this originating segment should be paid by the caller on the LEC bill. The IXCs do get some specialized services provided on their trunks, and they probably should be charged for those; obviously it is simpler for the IXC to get a validated originating billing number handed in with the call than to have to do their own subscriber authentication, but it seems to me that it should be optional for the IXC do make this "make or buy" decision. Since the cost of a timed local business call is about one or two cents per minute, the access charges should be in the range two to four cents. If that is what FCC sets for interstate access fees, it seems to me that they are staffed with people who can add and subtract. We should all lobby for some improved sanity in this area as we move into the "open network" where many subscribers want to get the same types of processing options that carriers have been getting.

Well, first of all, it's approximately 12 miles, not 18. 0-8 miles is Zone 1, 8-12 is Zone 2, and 12-17 is Zone 3. Over 17 is "local toll," until you cross your LATA boundary.

There are other factors that you have neglected, like population density. Lots of people live near the coast, in far denser concentration than most places 24 miles inland. There's also the fact that even with half or more of your calling area consisting of open water, you still have more people within 12 miles than in the entire eastern half of the state. Besides that, if we gave you credit for the so-called useless open water in your local calling area, we would then have to charge you toll rates to call the local dolphins, porpoises, and whales when they get cell phones. Besides that, you get to have the pleasure of watching guys with unbelievable tans walk up to one another and say, "Duude, like, your surfboard is ringing. Are you gonna answer it?"

Readers may be interested in what goes on behind the scenes with a complex selection such as this. 800 Expansion The question of the individual company's position regarding opening the "D" digit was asked. Sprint and MCI supported opening the "D" digit. USTA opposed, and noted that PBX software as well as end office software would have to be modified in order to permit this to occur. Bahamas Telephone stated that they had no difficulty either way, but that there could be a problem for PBXs. A poll was taken and opening of the "D" digit as a method for expansion was not accepted. Bob Hirsch noted that the OBF message processing committee requested that codes in the 88 range not be used because they are being used for billing purposes. MCI noted that they had asked their MSG committee rep., and they knew nothing of that concern. Of those present, none knew anything about the billing concern raised in the OBF letter. MCI proposed that we open an ERC, 888, for expansion. GTE asked for their rationale. MCI's response was that 888 was what their marketing organization asked for. GTE proposed that we start with 822. NANPA proposed that we start with 833 because it is consistent with the reservation of 533 that has already taken place for PCS 500, and that it would make administration easier for them. Bernie Murphy, SRCI, proposed that we start with 880. In response it was noted that 880 is not an ERC. GTE proposed that 888 not be used because it is unique and has special value because it has the same three digits. Madeline Bogdan asked what we were going to do with the OBF Message Processing committee concern about their current use of 88X codes for billing purposes. The option of starting with 888, then 877, 866, etc. was selected. USTA proposed that the expansion code is to be available for in service use on 4/1/96. AT&T pointed out that their marketing people would want to know with some certainty when the services would be opened, as certain of the numbers would be more desirable than others. AT&T also proposed that, if there was a problem meeting the 4/1/96 date the resource be opened as a non-portable code initially as a back-up to insure that the industry is not caught without resource to fill customer needs. It was noted that, based on current 800 number fill and demand rate, exhaust will occur on 4/1/96, so the industry has to be ready to go by that time. Bell Atlantic noted that they had checked this and could not be ready before 5/1/96. SBC noted that they'd be pushing it to make 6/1/96. Proposed recommendation to resolve the 800 exhaust: 1. 888 is assigned for resource expansion, and 877, 866, 855, etc. Are reserved for expansion. (recommendation) 2. 888 should be available for assignment on or before the 800 resource exhausts, but no late than 4/1/96. It is acknowledged that some networks may not be able to support the 888 relief plan until later than 4/1/96. (recommendation) 3. This date (4/1/96) is based on current available exhaust projections which indicate exhaust of 800 by the end of 1Q96. (concern) 4. Some 800 service providers stated that lack of 800/888 line numbers for any period of time is unacceptable. (concern) 5. Due to the potential for 800 exhaust prior to 888 availability, the industry must immediately consider reasonable steps to be taken to extend the life of the 800 resource and accelerate availability of the 888 resource. (Recommendation) It was proposed that following letter be sent to the CLC: Attached is an agreement reached at INC 13 concerning 800 resource exhaust and relief. This agreement is scheduled for final closure at INC 14. During our deliberations several significant issues were identified that require the industry's immediate consideration. These issues include but are not limited to: Implementation of the new numbering resource for toll free calling and the need to extend the life of the current 800 resource through review and possible modification of the existing 800 number administrative guidelines. Due to the confusion regarding forum responsibilities on the topics there is an immediate need for CLC to clarify where 800 assignment guideline changes and 888 implementation should be addressed. Several issues were submitted at INC 13 that outline more specifically the work that is suggested. Absent your direction, the INC believes these issues may not be resolved as expeditiously as possible and may result in exhaust of the 800 resource prior to the implementation of the 888 NPA. C.C. ICCF Participants OBF Participants 800 Ad Hoc C0-Chairs David Hanna, Bahamas Telephone, made a presentation on behalf of the 809 NPA administrations. In his presentation the Caribbean nations are requesting assignment of an N00 code for paid 800 traffic from the Caribbean, as a first alternative, with 880 as the second alternative. ------------------------------ Date: Thu, 16 Feb 95 13:57:37 EST From: GBOUWKA@ALLNET.COM Subject: Here's the Story on GETS Pat, Government Emergency Telecommunications Service (GETS) is a service offered by the Office of the Manager National Communications System (OMNCS) to meet the national security and emergency preparedness (NSEP) requirements of the defense and other federal telephone networks. GETS provides emergency access and specialized processing in local and long-distance telephone networks. GETS uses three types of networks: major long distance carriers (the big three); local carriers (Bell, independent, and cellular); and government leased networks such as the FTS2000 and Defense Information System Network (DISN). GETS uses a simple dialing plan and personal identification number (PIN). GETS is accessed through 1-710-NXX-XXXX from a phone presubscribed to ATT/MCI/Sprint (or 10XXX), or through FTS or DISN. The real value to the system is the fact that GETS traffic receives priority treatment through controls such as trunk queuing, exemption from network management controls used during network congestion, and enhanced routing to assure a higher probability of completion. The slogan of the GETS program manager is "When the going gets tough, GETS keeps you going". Wouldn't you like to have a GETS PIN the next time you want tickets to a special concert and you can't get through to Ticketmaster? [TELECOM Digest Editor's Note: Well, a PIN like that would be useful when trying to get through to the Skokie bus station for the Greyhound schedules, that's for sure. So it seems GETS and 'area code 710' are basically just new versions of the old ABCD keys (for various levels of priority) which were used in the old AUTOVON days. I assume one's phone has to be specifically turned on; you won't be able to access 710 until a flag is toggled somewhere in your central office which says to allow your use of it. Thanks for your answer, you are the first person here in my couple years of asking who has submitted an answer about 710.

In the original announcement there was something about "dual mode phones" and roaming between technically different systems. An American subscriber can roam a GSM (or DCS) net because his SIM card tells the GSM operator all it needs to know. There is however one catch here. The other way around doesn't work as smoothly. I suppose you've read the horror stories about US-Australian AMPS roaming here in the Digest. Intersystem roaming would be very easy if there only were some standard for SIM cards. Or at least if all new systems used some sort of subsriber ID-card. Questions: 1) Are any of the proposed American PCS systems going to use SIMs? 2) Are there any global standards been proposed for SIMs?

If the FCC wants them to collect $7 rather than $3.50 as the SLC, they can drop the nominal rate by $3,50 and collect the same actual amount of money that they would have otherwise.

The dial plan is being manipulated by a bunch of startup companies?? I don't think so! I am responsible for routing the calls for one of the smaller LD companies. The dial plan "problems" that I have encountered are with the LECS. For example, Pacbell in Los Angeles requires seven digits on FGA within the home NPA. USWest in Phoenix requires seven digit for "local" calls but you must dial 1+10 for toll calls within the home NPA. Ameritech in Chicago allows seven digits within the home NPA of 312. I don't even want to *talk* about SWBell in Dallas. These are hardly "startup" companies. We'll see how the "startup compaines" deal with the local dial plan when local dial tone competition really takes off. I would *love* to see some kind of consistency from the LECS.

He gave a simple announcement, asking people to contact him for further info. On mailing lists *I* run, that's considered good etiquette. Anything more becomes an advertisement, which I (and most of my readers) dislike intensely. TJC] [TELECOM Digest Editor's Note: Well you raise a good point where the ongoing -- and getting worse on this net -- problem of balancing advertise- ments versus infomercials versus solid information is concerned. I dislike very much running straight advetising here (especially when they don't pay me! ) and generally don't do it. If someone has the common courtesy to put their message together so it looks more like an infomercial then the line I draw is a bit more ragged. Some of them are more 'info' than 'mercial', and if it looks interesting I use it. What I am getting a lot of -- and I wish it would stop, but it won't -- are the notes from people saying 'gee, I found this great new long distance company, and it is really a bargain. Write to me and I will tell you all the details'. What they mean to say of course is they are an agent for the company; they don't have the brass bedsprings needed to just say so and float yet another advertisment on the net (what's the difference these days, one more or less), so they play tricks and *pretend* like they want to have a real discussion of LD carriers when what they do in return to your response is send you the canned file they have prepared. Now in the case of 'routers', I get more than I feel comfortable with of his messages ... let's put it that way. He seems to have the solution to everyone's problems in telecom, whatever they may be, in his office. When I run his articles, then I get messages from people saying 'well, that's the fifth one of his *commercials* you have run this month. ... etc'. So I have decided with some of these people if they want to send an infomercial I can run and talk about if it suits me, then okay, I will do it perhaps. But if they want to do a hit and run, quick and dirty thing about 'gee, I have the solution here, just write me', then I am going to put my foot down and say this platform cannot be used for advertising. I admit it is a judgment call. You are correct etiquette says don't advertise on the net; at the same time I would rather see an informative, well prepared infomercial which might benefit some readers than either an outright blatant commercial or a 'sneak one past the moderator' type which says 'I have all the answers, just write me'. In the latter case, they use my bandwidth to send a selected message to a few people that none of the rest of us (hopefully) benefit from. I see the onrush of commercial advertising on the net as something that is going to be very hard for even experienced moderators to keep in check as the advertisers grow more sophisticated in *how* they submit their material. I've had people write to me with deliberatly drummed up questions that were dumb as could be, and in good faith I would have published them and answered them -- albiet perhaps in my cranky, snotty way -- had not they then changed user names and sent me the *answer to the question* as a 'Re;' even before the original was published. Merely a coincidence of course that the answer involves products their company sells. Yeah ... they are doing that. Having discovered the question and answer, give and take format of the newsgroups, they use shills, or straight men to pose the initial commentary, seeking the advice of the net to solve whatever needs to be solved. Then bingo, here comes the answer from someone else at the same company, pretending like all we are doing is having an honest exchange of ideas, etc. "Oh gee, you mean fifty thousand people saw the answer I gave him about our product X ... gosh!" There is room for everyone on this net, including the .com sites and the numerous commercial enterprises which have came aboard in recent months, **but they have to play by the rules**. Yes, we want to hear about new products and servces which may be beneficial or solve problems, but no, we don't want blatant advertising. We don't want cross posting to thousands of news groups. We don't want you to cook up your own problems in order to have an entrance to present your own solutions. Just be part of us and participate in an intellectually honest way. In fact, the commercial enterprises on the net these days can be very valuable parts of this process we go through here, *if they will just cool it and follow netiquette.* Thank goodness this has not been as much of a problem here in telecom as it has been in some of the other newsgroups. We have for the most part a spendid bunch of people here sincerely interested in the unimpeded flow of information; and sometimes that information deals with commercial products.

Today's filing by the union's General Secretary Francisco Hernandez Juarez cited Sprint's mass firing of 235 Latino telemarketers in San Francisco on July 14, 1994. Juarez noted that the shutdown of Sprint/La Conexion Familiar, a subsidiary that sold long distance phone service to Spanish-speaking customers in the U.S., occurred one week before a vote on representation by the Communications Workers of America (CWA). Sprint committed "more than 50 violations of the law" during the workers' union campaign, as determined by the U.S. National Labor Relations Board, Juarez stated. The charges were filed with Mexico's National Administrative Office (NAO) for the North American Agreement on Labor Cooperation, the side agreement to NAFTA dealing with labor policies in Mexico, Canada and the U.S. The Mexican union represents employees of Telefonos de Mexico, the national phone system with which Sprint is trying to form an alliance to create a telephone network throughout North America. Juarez charged that the slow judicial process under U.S. law, and the absence of a prompt remedy to the violation of workers' rights at La Conexion demonstrates "the ineffectiveness of the U.S. law to comply with the principles contained in (the NAFTA labor side agreement) to which the U.S. is now obligated." The union leader called on the NAO to "declare that Sprint will not be allowed to establish itself in Mexico given its track record of abuses against workers until the company reinstates the fired U.S. workers and declares that it will "respect the rights of workers" and recognize unions in both countries when a majority of workers in a Sprint enterprise seek to unionize. The Mexican union also urged the NAOs of the three NAFTA countries convene a forum this year "attended by government, labor and management representatives from the telecommunications industry to explore ways to collaborate and discuss appropriate standards concerning workers' rights ... good paying jobs, as well as other important matters." The NAFTA labor side agreement provides for consultations among representatives of the U.S., Canada and Mexico up to the level of the secretaries of labor to resolve disputes over the lack of compliance with labor standards guaranteed in the agreement. The Sprint/La Conexion Familiar affair also has drawn concern from Sprint's prospective German business partner, Deutsche Telekom AG. The board of the German phone system, which is negotiating a 10-percent stake in Sprint, valued at $2 billion, cited Sprint as the inspiration for a new policy "ensuring that employer-employee relations customary in Germany are recognized and complied with" where the company "operates jointly with its global partners." Sprint's shutdown of La Conexion Familiar was the subject of a month-long trial prosecuted by the NLRB's Region 20 in San Francisco before an administrative law judge. A ruling is expected this spring. -- Communications Workers of America For further information, contact Jeffery Miller, CWA Public Affairs Department, 202-434-1163 ------------------------------ From: John J.

Starting January 9th, you'll pay $1.00 less per month. The remaining Touch-Tone charge no longer will be shown separately on your bill. Instead, the reduced monthly charge of $.80 will be included in your "access line" charge." My interpretation of this was that all customers would see their "access line" charge increased by $.80/month. However, I spoke to an Ameritech residential service representative, who told me the $.80 would be added to my "access line" charge. In other words, the "access line" charge will be $.80 more for those with Touch-Tone service. Then, sometime in the next three years, that will disappear too. (Probably the next time the "access line" service increases -- I predict by $.80!) In the meantime, Touch-Tone customers may not realize they are paying extra for it. Incidentally, the installation charge for Touch-Tone has been dropped (not sure if that's temporary or permanent), so I relented and finally got it. I guess the $.80 is within my threshhold of annoyance for having to switch my phones back and forth between tone and pulse. ;-) Bradley J.

We are doing research on Personal Communications Services commonly known as PCS. PCS could revolutionize the way people communicate. We could move from the current concept of one phone per location to one per person. We have designed a survey which can be accessed through a World Wide Web browser such as Mosaic or Netscape at the following URL: http://www.ini.cmu.edu/~ph2k/pcs/survey.html We wanted to ask readers of this newsgroup to participate in this survey, if they had the time. Trial runs indicate that the survey takes between 10 and 15 minutes to complete. Our survey focuses primarily on the following aspects of PCS: pricing, penetration, features for both residential and business users. Thanks!

Organization: AT&T Pat: My $.02 worth in three parts, carrier perception now, what is wrong with that perception IMHO, and potential ramifications for future wireless offerings (purely prognostication on my part). This is merely intended to share my experiences in a related subject. I hope no one takes offense at anything I've said. No finger pointing intended, only opinions based upon customer feedback. Addressing fraud is an amazingly complex issue that requires numerous companies to work together jointly when in fact they are competing against one another in the very same businesses and constantly seeking leverage against one another. It is a credit to the standards bodies that standards addressing these issues have been agreed upon by such diverse companies. Implementing same, is another story. No one company can implement the existing fraud and security standards alone. At that point, the only option is proprietary, which is what is being done now. All in all, it was a thoroughly frustrating two years in an unbelievably dynamic environment, and by far the most enjoyable job I have held with my company. BACKGROUND: I spent the better part of the past two years traveling to various cellular providers to attempt to get them to distribute our cellular privacy/security products. I had the unique opportunity to meet with carriers and their customers. Although you may wonder what this has to do with fraud, there are in fact many similarities between the two. For instance, addressing both requires something on both the subscriber and switch ends, whether it be a user pressing a PIN sequence and the switch understanding the sequence or a phone with privacy/encryption built in and complementary adjunct at the switch or on a desk. Additionally, one could argue that what C1 did in NYC just pushes the fraud out a level to the user (i.e. the calling card number you just gave the operator is now being used to someone elses benefit at your expense) which then enters the realm of privacy. There was and is an interested user base but the carriers are not interested. Why? (NOTE - that these are not my opinions but those expressed to me by carrier personnel from engineering, marketing, product management, sales,etc. from regional VPs to engineers and sales execs): THE CURRENT VISION: 1) Cellular is still profitable despite fraud/security implications. Carriers sign up record numbers of users each year. If you were reporting positive financials up your management line, would you change and open up a potentially huge can of worms that could undermine your financials given enough press? There is little financial incentive to do anything about fraud if the bottom line looks good already. 2) Digital will take over and have fraud protection (and higher security) built in. Within two years, analog will no longer be an issue and security and fraud problems will disappear. 3) I know some of my customers need it but I have to make a business case and I don't think enough people care. 4) Our sales forces only know how to sell phones. They have lost the ability to sell services. 5) We can't admit to our customers that our services are insecure! 6) Costs too much money -- the user will never pay for it. 7) If it were in a Motorola flip phone, we'd buy it in a minute. 8) Most importantly, customers (including myself) continue to pay their monthly cellular bills, which cover the operating expenses for the carrier (including losses from fraud) and provide a tidy profit as well. WHAT'S WRONG WITH THIS VISION: 1) Analog subscriber growth continues at a record pace. What is not taking off is airtime for potential high usage business users. So, carriers are now looking for new services to offer (voice messaging, data, etc.) to attract same. None of these services (or for that matter the basic cellular service) offer enhanced security (that meet the standards of many corporate security instructions) or built in fraud protection that is an inherent part of the switch and phone and yes for many reasons, digital is just as insecure as analog (we can debate this in another forum if you like). I read a recent report (WSJ I think) that fraud in the NYC area cost the local carriers $60M alone last year. But if I had to guess, I'll venture that the financial picture for the NYC carriers show positive Economic Value Added as the numbers get passed up the corporate financial hierarchy. Fundamentally, I believe there are two reasons why business customers limit air time -- cost and security. Cost could be driven down if fraud could be controlled. Security could increase call-minutes (and therefore carrier revenue), and like fraud an optimal solution involves both your subscriber piece and the switch. There are implications here for PCS (see prognostications below). I have heard many stories how employees have been given cellular phones as perks and been told not to use them for business. 2) Two years ago, digital was going to replace analog by 1998. Thanks to multiple digital standards, analog now has a rosy future. In a recent quote in Mobile Phone News 12/12/94, Motorola says "Digital accounts for less than 5% of cellular growth in the U.S. As of October 1, there were 21.5 million analog users in the country, compared with 250,000 subscribers using TDMA..." I have been told by Motorola, Nokia and NEC personnel that the bread and butter for the subscriber equipment portion of their business will continue to be analog for the forseeable future. Actually, I would think that the thought of replacing 21.5 million analog phones would be an incentive for manufacturers to use any excuse to create a new analog version of existing phones with fraud and security built in. As an aside, when the Bar Associations in NY, MA, NH and other states rule it is unethical for an attorney to discuss client matters over a cellular phone, they are not differentiating between analog and digital. From this I could draw one of two conclusions; either the carriers have done a poor job of positioning the advantages of digital to the user or maybe there are none. Anyone offering odds that CDMA (with whatever security/fraud standards are decided upon) will be rolled out in a diluted version first sans some portion of those standards? 3) Financial responsibility is extremely fragmented in cellular. A good general rule is any addition to the MTSO needs to be cost justified for that MTSO. This affects fraud/security in two ways. First, it dilutes the business case by forcing the regional managers to look at each expense (not unreasonable). The net result is that corporate tends not to look at the problem as something it needs to be involved in because it is regional in nature. McCaw San Francisco certainly has more fraud potential compared to McCaw Oklahoma, so let San Fran fix their problem. Second, it removes the corporate clout required to implement a solution within subscriber equipment. Since corporate usually negotiates subscriber equipment purchases, regional managers have zero chance of independently approaching a major manufacturer such as Motorola, Nokia, etc. If they are allowed such independence, their numbers and therefore bargaining power are still reduced. 4) Just an excuse for asking your sales people to sell high priced basic service and higher priced enhanced services to a varied customer base. If my salary depended upon attaining a sales quota, you know I'd be concentrating on selling basic service and a Motorola phone to the "average" customer. It's the easiest sell. 5) I would assert that the press is doing an adequate job of this on the house. Also, isn't C1-DC's denial of roaming in NYC a tacit admission that they have no control over the fraud problem in NYC? Ditto for the Nynex, Bell Atlantic, C1-NY PIN deal. And you know your in trouble when publications such as {Woman's Day} (7/20/93) say things like "So, if you'd rather keep your personal conversations private, make and take them on an old-fashioned, wired telephone". Still, fraud and security are an extremely tough sell. There are Fortune 100 companies whose security departments routinely monitor executives cellular calls and provide them with transcripts. I have given equipment to CEO's of some of these companies, only to have it politely returned with a note indicating that they didn't see the need. Very likely, these same executives have appeared before Congress in the last couple of years to complain about their losses from foreign intercepts by the French, et. al. and they probably haven't addressed that problem yet either. Losses due to communications fraud and lack of security are too intangible to measure by the average user that has to date been left in peace (or at least is unaware of events to the contrary), let alone the carriers (the press seems to be doing OK with this though). Now if your carrier sent you a letter saying that effective immediately they were doubling your monthly rate and call charges to cover losses from fraud or told you that you would have to exchange your existing phone at your cost, would that get your attention? Not to worry, they wouldn't risk losing the profitable business that they have by being so rash. 6) Maybe true. Its amazing the excuses that people give for not buying products to protect them against fraud or intercept. It's too big, heavy, costly, don't like the voice quality, wanted blue instead of black, doesn't say Motorola on it, and on and on. However, the biggest excuse is that human beings tend not to take responsibility for the problems that occur, especially when their insurance does not cover the loss. When a user is "hit" (and they often don't know that they have been), they believe it is the responsibility of the "telephone company" to protect them or cover their losses (Ma still lives on in spirit). You need only look at the reaction to PBX fraud as evidence. To their everlasting credit (and the good of their financial picture) telcos/carriers are perpetuating this "feel good" spirit by continuing to cover the losses. The extra price of security and fraud control equipment is tangible, one can look at a purchase order and see the difference. The losses due to fraud or lack of security can disappear at many finance levels with creative accounting. If users were truly concerned, then there would be many more than 250,000 TDMA subscribers now. For all its shortcomings, TDMA does have better authentication, although initially this may not have been the case. By the way, this is only a guess but I'd bet that the PIN arrangement is required for both dual mode and analog phones. Can anyone confirm this? 7) It is very difficult if not impossible to get major phone manufacturers to make changes to cookie cutter subscriber equipment to add anti-fraud or enhanced security, even if it adheres to TIA standards. These pieces are produced in lots of hundreds of thousands at a clip. Carriers have painted themselves into a corner on subscriber equipment -- they have given it away at a loss for so long to get customers to sign up that customers have grown used to getting the equipment for free or minimal cost. Carriers are loathe to change this successful equation. My Motorla digital flip user guide clearly stated that enhanced privacy was only available for digital calls. Typical of the industry last year was the decision to move forward with digital and refrain from adding features such as enhanced privacy or authentication to the soon to be replaced analog system. I never did find an area where the switch supported the enhanced privacy feature that the phone had. Maybe the industry has changed its mind by now. But that still leaves a minimum of 21.5 million pieces of analog subscriber equipment that do not support any potential improvements to the switch, and those numbers increase by thousands every day. Sounds a bit overwhelming to me, but I am still of the opinion (eternal optimist that I am) that it could be done by any of the carriers if managed properly. 8) Well, I guess that says it all. I still pay my monthly bill but I don't turn the phone on much any more. I used to be able to take care of business while driving between Phoenix and Tucson. It made me much more efficient. My cellular bills used to range between $300 and $600 a month (and I didn't violate Corporate Security Instructions because I had an attached encryption device that I used faithfully). Then I made that one clear phone call (sheer convenience) to make my travel arrangements to show my equipment to BellSouth in Atlanta. Amazing how on a direct flight from MHT to ATL my luggage was broken open and five cellular phones, a scanner, and an ESN reader were left untouched, only the encryption/privacy equipment was destroyed. Since I changed jobs and gave my encryption devices back, I no longer travel and have a need to stay in touch and be more efficient in my new job (at least my new management probably isn't interested in paying that much for more efficiency). Now I try not to turn the phone on near Boston to let the ESN readers and scanners pick up someone else. I don't even like to call home and find out my kids are home alone much less let the world know it. I use the phone for directory assistance and calling stores. Makes me a much more efficient shopper. Still its hard to pass up a $.10 pay phone (still have it here in NH) for three minutes knowing it will cost me $1.50 on the cellular. Come to think of it, why do I need cellular service? It's not as useful as it used to be. PROGNOSTICATIONS (my favorite): 1) Carriers need to get analog right. If you attend a regional C1 wireless expo, you will hear that PCS is already here today, and the speaker will hold up a dual-mode phone and describe all of the nice services available, meant to make your deskphone expendable. In reality, that analogy is based upon the ubiquity of analog service. The concept of communications any time, anywhere is only available now because of analog infrastructure. To date, carriers have shown no propensity to strengthen the notion that the wireless "deskphone" as it exists today is as secure and fraud resistant as the wired one (which is already on my desk and costs a lot less to operate). They have already entrenched in customers minds the standards for PCS; expect more of the same. They have made PCS sales much more difficult. PCS sales people will have to overcome the weaknesses of analog, something digital has not been able to do to date. 2) Note several disturbing trends in the carrier responses to fraud. First, every carrier that attempts to deal with fraud is implementing its preferred method and they are dissimilar. I have to wonder if the Nynex and C1-NY PIN strategies are compatible. Second, anti-fraud efforts are concentrating on local territories. Your Nynex PIN is probably worthless on the West Coast where you probably stand at least an equal chance of being cloned. Third, all the "fixes" are user impacting and represent a step backward from direct dial capabilities. In an age where cell phones are now being sold with dial tone (ostensibly to get users to transition more easily from the deskset), we are now faced with the probability that we either have to enter a PIN or talk to an operator (none of which I have to do from my deskset). These are interim steps for an analog system that will continue to be much more than an interim system. This interim analog system is the test market for enhanced PCS services and the response will not be "knock the door down, let me get this thing" if the price of these services are lack of security and increased exposure to fraud. There is at least one district director whose carrier employer is committed to enhanced services that recognizes the risk he takes every time he powers his current generation PCS vehicle (aka cellular phone) up, places or receives a call. 3) The entire concept of the Wireless PBX is doomed unless security and fraud are addressed and solved both in the Campus environment and with the particpating carrier. Too many corporate security instructions exist which preclude discussion of proprietary business over cellular phones. Keep in mind also that with the winding down of the cold war, many ex-government security folks are now being hired by major corporations to address the security weaknesses of these companies, and they do know the score.

I just want to know if the firmware allows it, and how. The firmware allows it. Without the manual (or the hint below), you'll never figure out how to get it. (No fair tracing the firmware....) Anyway, the firmware you need is Feature Package 3 (FP3) or later, with an ADM-2. With phone powered up, hit SELECT and then TEST. After the neat self-test finishes, the display will show the FPx.y level and firmware date. (It will also emit this annoying "BEEP" until you hit SELECT and TEST again.) If you are at FP3.0 or later, you should have the "ISDN ADM FP3 Users Guide," 555-021-729 to tell you how to use it ... but the real power user also needs "ISDN API Programmers Reference Manual", 533-705-200. FP3 supports: - D or B-channel data (X.25 or "raw" on the B-channel) - a basic monitor capability for voice or data calls (see below), - a version using Hayes(tm) AutoStream(tm) / to monitor for both, - a range of Human Interface monitor capabilities that will report button presses, switch-hook, key presses, lamp status, volume, sound/alerter status, etc. - a "control" capability that allows the ADM to actually break the Human-to-CO interface and control calls, sound, buttons, etc. (The alerter will play tunes within reason....) - AutoStream also allows the ADM EIA-232-D port to intermix data (D or B-channel) with these controls. (There is also a NETBIOS modified interface from EXCELLTECH available to support up to 4 7506's from a PC. Never tried it myself ...) Anyway, to get the most basic voice monitor capabilities, set the 7506 Data capabilities (SELECT, then DATA) to: - 9600 or higher (the ADM will autosynch unless you block it) - "EnhAT" mode (not "AT" or "CMD") - Parity and Data Mode shouldn't matter. Now hook up your terminal/emulator to the ADM port -- type "at" and it should say "OK". If not, see Users Guide .... Now enter "at&O1" (you want to monitor with ID 1) Then enter "at%A0=3" (you want to monitor VOICE with ID 1) Then enter "at&&X0,0,98" (this turns on Enhanced monitoring results) That should do it. Here's a captured stream from my work phone (7506). The PARTY, CAUSE and SCA lines will not appear except in Enhanced monitoring mode. Good luck. I didn't design this interface -- I just use it ...

(Remember > that brag?) I'm not sure how this thread turned into a Microsoft-bash; I realize it's trendy, but it's not relevant to this discussion. The point of my posting was that ADSI is a non-scalable voice/data solution, obsolete before it ever reached widespread adoption. Rather than adopting an antiquated technology, we should be looking to newer, more flexible voice/data schemes. I was also not advocating a "pie-in-the-sky" solution, as John insinuates. However, it is important to see technology trends and build a plan which allows us deploy today and move toward the future with a minimum of fuss for users or providers. One approach may be to start with Radish's VoiceView, which DOES work on the ubiquitous analog line through any kind of switch and even from behind a PBX. The architecture that applications are built on to use VoiceView allows the transport to be replaced later with DSVD, ISDN, ATM, or whatever without changing the application. This is the kind of future we should be working toward -- ready today, ready for tomorrow. Furthermore, these technologies don't have to live in a box which looks like a computer. I totally agree with John that there are lots of people who "eye a PC with suspicion/derision." So for these people, there are companies building screenphones which support VoiceView and computer companies building devices which don't necessarily look like the computers we have today. As far as adoption goes, there are roughly ten million modems sold each year, most of which will be VoiceView equipped by this time next year. Contrast this to <1,100,000 screenphones (including proprietary non-ADSI phones) in TOTAL deployment by the end of the year (according to a Falkner&Gray report. What's more, since the PC industry enjoys a more favorable price curve than any industry, the price of PC-based solutions (including PC-based screenphones) should drop faster than non-PC based telephone hardware, thereby further widening the gap. Which user base do you want to develop for? (Hint: more is more.) Heck, I'll even bite on the Microsoft Windows NT in the back-office non-sequitor. NT is already being deployed in the network -- GeoTel makes an SS7 box built on NT. What's more, people like Octel and InteCom have already announced that their next generation systems will be built on NT. Over the next five years, you'll see NT moving into PBXs first and then into the CO (slower here due to inertia). I'll make a gentleman's wager with you, John, that by 2000, Windows NT will be commonplace in PBXs and CO's. ADSI is not a good solution, and, contrary to John's assertion, without Bellcore to advance it, it will never grow to support richer user interactions. Even with Bellcore's help, it will likely never grow up. In discussions we've had with folks in the telecom industry, it's clear that most of these people realize ADSI is a dead technology, so I'm not sure who will propagate and grow it. I think John's story about GTE giving away Caller ID boxes sums up my primary argument: if we take a heads-down-how-do-we-make-money-right-now approach without thinking about what the future brings, we will wind up screwing ourselves like GTE did. So before you think about deploying ADSI or building ADSI-based products, think about what your next step is what that step will look like for you and your users. You'll realize it's a doozy ... And, yes, Windows 95 will ship in 1995.

I would guess that a large number of your calls are being automatically recorded by equipment owned by friendly and unfriendly nations. The "world" may very literally be listening to your cordless calls along with many others in the Washington area. Increasingly, also, government intelligence agencies in many countries around the world support their domestic industries by passing along relevant technical or business information they run across in the course of other collection efforts. A recent investigation at Vandenberg Air Force Base, at which I work, uncovered evidence that the French intelligence agency was systematically collecting such information on the activities of forty cont- ractors working in the area of commercial space launch services. This according to reports in the paper, of course.

I have been reading this journal now for over six months and find it totally enjoyable. I have been particularly impressed (depressed?) by the number of situations that arise for bureaucratic megalomania. Coming from New Zealand and having worked for both of the major players in the Telco arena, I can only remember our bad old days. I have had numerous 'pre-competition' experiences with the billing systems and general customer service ethic of the governmental monopoly. CLEAR Communications came along and just like MGM Magic (Wires, mirrors, that kind of thing..) suddenly 'I' was important. Very similar to Richard Wildman's MCI experiences, TELECOM NZ were forever cutting people off for non-payment and then having to re-instate their service after a 'clerical error' was detected. The worst bit was they did not even have the decency to be embarrassed. Now, if I don't like to look of my bill, I can choose between five different formats, I can receive the account at any one of four times during the month (handy when the relatives live overseas and the bill usually arrives at the same time as the mortgage). Chances are, if I don't feel I should pay for a call, they will credit it back. If they make a mistake and I am without service for 24 hours (even due to a cable fault), I will get $50 in phone cards or $30 off my next bill. If my call is not billed in 90 days or if it is billed incorrectly, I will not be billed for that call at all, and I may get the erroneous amount as a credit also. This generally applies to both carriers. In the specific instance of CLEAR, I can get a 45% discount off my calls, just by talking for more than 30 minutes, any time of the day. If I call another person who uses CLEAR, I get an additional 10% discount. If I get a friend to join CLEAR, we both get $10 credits on our next bill. etc etc etc Although I am not saying anything against the United States in general, sometimes I think that the Telco's there need to remember just who pays the bills. It is the guy who can't get his modem to work because the line if out of spec., or the person for whom they just can't get that second line right, or the person who is getting just a little bit frustrated with the companies inability to realise when it's made a mistake. It seems to be way past due for the employee to realise they are lucky to be working at all, and the only reason they are is because the company they work for hasn't gone bust due to the 'little' people paying money for 'service'. All of the above in in my humble opinion, of course.

I work for the University of WI- Madison in a dean's office. Many of our phone calls are from students who want advice on how to go about transferring to the UW, which courses to take, how their courses at another institution would transfer, etc. What I want to do is have an internal modem inside my PC that takes the caller-ID information. The only modem I've been able to find that *for sure* does it is a ZyXel U-1496-B. However, the cost of it is more than I can justify to our department administrator. Which other modems have this capability? Am I being completely unrealistic in trying to find an internal modem with this capability for under $150? Secondly, what's available for software? My computer is infected with, or rather, runs (almost) under Windows 3.11. What I need is a pop up program that is always running. When the phone rings I want it to show me the ID, and if there've been any notes taken on a previous call from that number, to show me that as well. Furthermore, it's gotta be robust -- I don't want to see "General Protection Fault" messages! Any assistance that readers can provide would be fantastic. I tried calling just about all of the local computer stores and the responses could, for the most part, be boiled down to "Huh?!" The most pathetic one was Inacomp, whose representative insisted that Caller-ID was a "standard 1200-baud modem signal" and that all I needed was software. I referred him to this months article in {Byte} magazine and got off that call as quickly as possible!! The most informed sales rep I talked to knew what caller-ID was and that there were modems that could decode the signal, but said that there just wasn't any software available yet that could do what I was looking for.

Date: Thu, 16 Feb 1995 18:13:58 EST Congress has declared today to be Haleyville, Alabama 911 Emergency Call Day, according to a report broadcast on National Public Radio this afternoon. According to NPR, the first emergency services call to use the (then) new emergency number, 911, was placed in Haleyville, Alabama, on this day in 1968. The 911 system in Haleyville was put into place by Bob Gallagher, of the Alabama Telephone Company, and, among the inaugural callers was the president of the Alabama Public Services Commission, "Bull" Connor, perhaps more famous for siccing dogs on schoolchildren. According to Mr. Gallagher, he ordered the activation of 911 in Haleyville in part because AT&T had planned to have the first 911 call placed in Huntington, Indiana one week later. He noted that the mayor of Haleyville (pop. 6,000 at the time), was quite proud of the 911 emergency number and ordered large signs put up at the city limits announcing that in his town, you could dial 911 for any emergency. Gallagher also said that the underlying motivation for 911 was to cut down on operators' non-revenue time, such as that spent handling emergency calls. That might have been his company's attitude, but it doesn't sound to me like the typical Bell System attitude of that time.

Odd that you say this ... almost every other LD carrier's calling card system, including Sprint, LDDS/Metromedia, and WilTel, do NOT supervise UNTIL the called party has answered. I can thus sit on the cellphone and enter calling card numbers all day to a busy number and NOT be billed (well, except in LA! :( ). AT&T is one of the ONLY carriers that I am aware of which starts 0+ billing BEFORE you even enter your card number. This is why I don't use AT&T from my carphone for calling card calls, and why I've obtained LDDS/Metromedia cards for everyone who works with me as well as other friends with carphones -- precisely so they don't have to pay to reach a no-answer or busy-signal as they do with AT&T Calling Card Calls. > While you may not "PAY" for the time that you spend programming the > service, I do not really want to give you free use of my most scarce > resource (radio channel time) while you are setting things up. Ok, fine. How about I write some software program which looks to the caller ID of a call from a cellphone. (You can get an 800 number to do this if your cellco doesn't send caller ID). When my Mac or PC gets this specific Caller ID or ANI, it goes into "ring detect mode". When it gets into the detectiom mode, it calls the carphone (or beeper) and rings it once. It then proceeds to count the number of rings which follow, with an allowance of maybe one ring either way. After "x" minutes, it stops looking for rings, and counts up all the rings with the given cell co's caller ID. I pre-program the software to know that 1 ring = forward my 500 to 555-1212 2 rings= forward my 500 to 555-4141 3 rings= forward my 500 to 555-6161 ...etc. So if the software received three rings with the cellco's ID (or one of the many cellco IDs), it says "Hmm ... three rings means forward the 500 number to telephone number 555-6161". My calls are now forwarded, I didn't pay a dime in airtime (except in LA, where pressing SEND costs airtime :( ), but I managed to use up a lot more system overhead than if I were able to reprogram the 500 at no airtime cost. Awkward? Yes, indeed. Time consuming? Yes, for both of us. And I have it up and running right now, and it works quite well. The software was simple enough to write, and the 800 service and configuration of the whole thing took a few hours more. So is this what you prefer? Is this REALLY preferable to allowing users to program -- not call anyone mind you, just program -- their 500/700/whatever numbers with no airtime charge? (And please, no arguments about how this is theft of service, etc. We went through this before, I thought both sides had interesting points, but I chose not to participate and do not wish to engage in that now. That is NOT the topic of this post.) The "You use our airtime, you pay" is a very narrow-minded approach. First off, the only reason I would *want* to access my 500 number for programming is to forward calls to the car while I am there. By charging customers airtime to call their 500/700 numbers to reforward them to their carphones, they are discouraged from doing so, and will receive fewer or no calls in the car. By being petty and cheap, the carrier is depriving itself of significantly higher revenues. Most people can reprogram their 500/700 numbers in 20 seconds or less. A single, one-minute incoming call can easily make up for that supposedly "lost" revenue, and after the initial minute, a cellular company which did NOT charge airtime for 500/700 programming (assuming AT&T did not preclude that option as they currently do) would gain a great deal more in airtime revenues for subsequent calls -- revenue that would otherwise have not been generated. As an example, frequently, I would like to have my 500/700 numbers forwarded to my car. They are usually forwarded to my pager. Instead of having an easy mechanism by which I can do this without charge, I need to use my software to do this, which is admitedly annoying, especially on short trips. So I normally just keep my 500/700 numbers forwarded to my pager or voicemail (which is then paged). If I get a page while in the car, I will almost always wait till I get to a landline phone, and return the call from there. Not because of any strong desire to "spite" the cell co. (I like my local cell co., actually), but just because I can say "Hmm ... ok, this guy can wait ... no need to talk this very second". However, if I were able to reprogram my 500/700 number(s) from the car with no charge, and a call came in, I'd be inclined to answer it, and thus generate revenue for the cell co. Secondly, as cellular and landline networks become increasingly integrated, the ability to control these "follow me"-type 500 services will begin to be incorporated into the combined functionality of the cellular and landline switches. As the distinction between the two becomes increasingly hazy, many of these services will be accessed in a similar manner to current "feature codes", such as call forwarding, which in most cases (Err ... Pac*Tel/LA and/or LA Cellular being the exceptions? ;) ) are not charged for. If AT&T wishes to have its 500 services maintain some sort of competitiveness with integrated landline/cellular services, it would be in its own interest to allow airtime-free 500 reprogramming, at least from its cellular properties, as well as to make haste in developing links to integrate its 500 services with its cellular services in a more seamless manner. Thirdly, the fact that other companies who have calling card services which do NOT supervise and which will not (generally) incur an airtime charge (again, let us forget about LA's cellular "services"), indicates that not only are people eating up "precious" airtime, but that they are "getting away with it" all the time. What happens when Sprint decides to add a few extra features to their calling card services, like the Time of Day, maybe? They don't need to supervise this to bill. Or what if they wish to provide ancillary services to their calling card system, like speed dialing? If they don't supervise while a user is programming their speed dial numbers into the calling card system, what is a cellular carrier going to do? Where do you draw the line and say "OK, at point 'x' you MUST supervise" to a given carrier? AT&T has IMHO foolishly opted to do that right from the onset, yet other carriers have more enlightened policies. The poster's notion of a cellular carrier dictating to the entire communications industry when *they* must offer supervision (prior to an actual answer, which should of course be supervised) smacks and such unmitigated arrogance that such a carrier's protestations are at best ignored. > It is not really AT&Ts place to chose for me which calls I bill for > and which I do not by selectively manipulating he return of answer > supervision.

I'm sure they will be very willing to cooperate with you ;). You know, when their calling card system picks up and prompts you for a calling card, well, that's a machine. Tell them that.

Well, maybe Pac*Tel managed to get out of offering its customers 10xxx dialing by changing it's name to "Airtouch", but a good deal of carriers DO indeed offer this as a result of federal rulings. And with McCaw Cellular (unfortunately) being forced to offer Equal Access (one of the few cases where I have been opposed to this), I suspect that a MAJORITY of subscribers nationwide will have 10xxx dialing. My point was not to allow 500 direct billing (which could be manipulated to place international calls without the cell co. knowing -- see Pat's note at the end of a recent post regarding 500 numbers from hospitals). The point was that since the 500/700 services are designed to have inconsistent billing rates to allow for international forwarding (a difficult, but understandable compromise on AT&T's part), the only way that one SHOULD be able to access the 500/700, in order to PREVENT a cellular company from suffering an intentional or unintentional loss is to ALLOW access to 0+500 or 0+700 with NO AIRTIME CHARGE until the called party is reached. AT&T may wish to consider that their competitors' 500 numbers may work just like this: They will not supervise until they complete. Cellular customers, even those on it's newly acquired McCaw properties, may desert AT&T's 500/700 services for a service from an Ameritech or Bell Atlantic, for example, which allows a user to program and forward his/her 500 number without airtime charge, and which does not bill callers UNTIL the 500 number is answered. The main point was that AT&T has made a foolish move in this regard, and that hopefully other 500 providers will emerge who will not repeat these errors and provide a more "carphone friendly" service. It is ironic and sad that AT&T, which now owns the nation's largest cellular provider, was unable or unwilling to make the necessary adaptations to its 500 service to facilitate these goals, and it seems increasignly likely that another IXC or Bell will introduce a 500 service that is more "carphone friendly" than that offered by the AT&T/McCaw. > Phil Ritter pritter@la.airtouch.com Ahhh .... although I am not personally attacking Phil, and I do appreciate his taking the time to answer, if this signature file means "Airtouch Cellular in LA", then I can understand the response. The LA market has unquestionably the WORST cellular service of any large city in the nation. Calls are always dropped, coverage is incredibly poor, and on top of all this, both carriers have audacity to charge airtime from the moment you press send and the switch accepts your call. If you hit *350 to turn on call delivery with LA Cellular, there's an airtime charge! Or if you try to forward your calls on Pac*Tel, another airtime charge! There are airtime charges for busy signals, for calls which don't complete, for fast busy (non-switch) signals, for "Not in Service" recordings, etc. For just about anything you can dial, with the exception of maybe 611 and 911, there is an airtime charge. And what do LA Cell and Pac*Tel (err ... Airtouch ... don't want to get the DOJ involved...) say when one dares to ask them why they are the only two carriers who do have such a practice? "Well, it is because our channels are so saturated with callers that we NEED to charge this." Really? So how come both providers in NYC, a city more densely populated than LA, with similar traffic conditions (if not worse) can mange to get by without charging for incomplete calls, AND still build out their systems and expand? (In all honesty, CO/NY bills for incompletes over 40 seconds, NYNEX/NY doesn't bill for incompletes at all.) One of the carriers, Cell One, has excellent coverage just about everywhere -- from inside the lower, "RF-resistant" floors of buildings in Manhattan to the hills and valleys of Westchester and Rockland counties, topographically more challenging than anything in downtown LA or in any of the canyons of the San Gabriel or Santa Monica ranges. I recall what service was like before McCaw took over -- sort of like LA. Dropped calls, blocked outdial attempts, and the near impossibility of actually receiving a call. In a few years since, I can say that there is hardly an area in NYC where there is any significant dgree of prolonged static (compated to I-5 up in the hills, or on the I-405/Simi Valley Fwy JCT), let alone dropped calls, even right in the middle of the rush hour. So how does CO/NY manage to provide such excellent service, in an equally if not more complex service environment than LA, and yet not start charging from the second a user presses SEND? The fact of the matter is that LA Cell and Pac*Tel/LA are just greedy, petty dinosaurs of carriers who will do whatever they can to get airtime revenue, smugly convinced that they can sit on their licenses and that nothing will ever break up their nice little duopoloy. Pac*Tel is even arrogant enough to tell its users "When you roam out of LA, there are no incomplete call charges", as if they are taunting "We know no one else does it, and we just don't care. If you live in LA, you are stuck with us." Call their (hopefully free) roamer info number and you will hear this. Moreover, resentment of these two "carriers" doesn't stop at the customer level. I've spoken to a number of roam coordinators in New England and Mid Atlantic cellular properties, who have all told me that even if it weren't for fraud, they would not offer automatic roaming in LA because of the number of complaints they get regarding incomplete calls, which almost universally are written off as a courtesy credit. It is because of these two carriers that I and no doubt others are anxiously awaiting the time when alternate services, such as Nextel, develop sufficient coverage and RF saturation to adequately serve the LA Basin area. As a result of LA Cell's and Pac*Tel/LA's unbearably poor coverage, but more so as a result of their sickeningly duopolistic billing policies, I am sure that *any* alternative to these two will be enthusiastically welcomed.

Once they (a hacker) can get a call through your switch to this numbber, they will receive voice prompts that let them add-on calls to about anywhere on the planet. Furthermore, they can use a long (1 second) pound key to let conference bridge add on and disconnect calls for up to five hours (according to the last brochure I received). Thus, the one call to the conference bridge can allow many more to be generated. The bill for all this calling will ultimately go back to the PBX owner. System administrators should be sensitive to this number that can easily result in a $1000 phone bill for a single slip-up. OTOH, if you're a legal user, its a pretty good conference facility.

This concept involves two phone lines and a device designed to answer a ring on one phone line and connect it to a second phone line. The idea is to dial one number, get dial tone from the second line and then place an outbound call from that point. The subscriber of the second line will eventually get the bill. For it to work, the normal users of the lines need to not answer the call. (like when they're out) I believe the term comes from the idea that the device "clips on" to the phone line at any point between the residence/business and the central office. Man holes, unlocked wiring closets and a zillion other points between the subscriber and the C.O. are possible points to add such a device. It was mentioned in the FCC requies for information on Toll Fraud that came out about a year ago.

I'm sure that this method was used on the standard 1.25VDC ni-cad cells, and not a multi-cell one used for cellular (many are in the 6-9VDC range I believe), so your mileage may vary.

So don't forget that if you have voice mail and need message waiting lights for the remote location, youll probably not be able to pass the voltage necessary for MWI's. These are key for our operation. Our NEC has digital remote units that allow their digital phones to be used up to 50 miles away from the main site over a PSTN T1. You get 23 phones that act just like the ones in the office. A great solution if a tight integration is needed, but you still need to provide for fax/modem lines.

We have a two day on-site only intro course called Learning to Talk the Talk and Walk the Walk of Telecommunications which can supply a conceptual framework for more advanced courses. It is designed in three parts with a logical progression for easy understanding. Part 1 explains the Underlying Technology Basics, Part 2 is a Walk Thru A Telephone Call, and Part 3 is a Walk Thru a Data Call/Transfer. Because we only do on-sites our overhead is low and we can do our courses at prices that even very small companies can afford. Zap me an Email for more info. I am not making a value judgment on any of the other courses because I haven't seen most of them, and it's generally been my experience that tech courses with a lot of Ph.D. presenters can be very valuable. That is, if you already have an understanding of the underlying fundamentals. I do wonder though if the academic climb to Doctorism doesn't sometimes mean a loss of contact with things physical. An example: I was attending a class on networking being delivered by a noted Ph.D. Very knowledgeable, and a nice guy to boot. When he got on to the subject of transmission systems, it was obvious to me by his answers to audience questions that he had never actually worked on one. He gave out some erroneous information because of this. No lives hung in the balance because of these errors, so I did not correct him in public, but did discuss the issue after the session. My point is, no one else seemed to notice the errors because they too must not have had operational experience which would have given them a base from which to judge technical accuracy. More importantly from my perspective was his veracity on those subjects which I had no previous knowledge and thus had to simply trust as being correct. No one can be expected to know everything, but it sure would be nice if somebody could invent a B.S, M.S, PHD (BS, More of the Same, Piled Higher and Deeper) filter so we ordinary folk could separate facts from fictions. Someone once told me that the word EXPERT derives from X = unknown quantity and SPURT is a drip under pressure. I'm always cautious around unknown pressurized drips and advise others to be so too. [TELECOM Digest Editor's Note: It is difficult at my position here also to separate fact from fiction at times, but I have found the majority of the conference announcements presented here to be very high-calibre in nature. Particularly good are the short course announements I receive regularly from Berkeley, one of the insitutions providing this Digest with computational facilities for newsletter distribution, etc. You do raise a good point though, and perhaps some of our readers will contact you about a course in the 'basics' to help them get a running start on the more difficult stuff which comes their way.

Looks like this guy never read the rules, and the FCC got pretty ticked off ... From FCC DAILY DIGEST Vol. 14, No. 32 February 16, 1995 Report No. WL 95-1 WIRELESS TELECOM ACTION February 16, 1995 COMMERCIAL REALTY ST. PETE NOTIFIED OF APPARENT LIABILITY FOR FORFEITURE OF $390,000 FOR VIOLATION OF IVDS AUCTION RULES The Commission has notified Commercial Realty St. Pete, Inc., that it is apparently liable for a forfeiture of $390,000 for abuse of the Commission's processes and violation of its rules in connection with the Interactive Video and Data Services (IVDS) auctions. In addition, Commercial Realty may be liable for penalties of not less than $1,237,500 as a result of its failure to tender the required down payment for licenses for which it submitted winning bids. Commercial Realty communicated with other bidders in violation of the FCC's anti-collusion rules, falsely certified that it was financially qualified to fulfill its bidding obligations and falsely certified that it was entitled to designated entity status as a woman-owned business. The Commission is also issuing a separate Order to Show Cause requiring Commercial Realty and its principals to show cause why, in light of their apparent misconduct in connection with the IVDS auctions and investigation of Commercial Realty, they should not be barred from participating in any future Commission auctions and why they should not be prohibited from becoming Commission licensees. On July 28 and 29, 1994, the Commission conducted auctions for 594 IVDS licenses in 279 markets across the nation. Winning bidders were required to pay 10 percent of their winning bids within five business days after the close of bidding. Commercial Realty submitted winning bids in 20 markets for a total of $41,250,000, requiring a total down payment of at least $3,266,750. Commercial Realty never tendered its down payment. Commercial Realty claimed designated entity status as a woman-owned business and claimed a 25 percent bidding credit in most of the markets in which it was a winning bidder. Commercial Realty was the successful bidder in Detroit-Ann Arbor, MI; St. Louis, MO; Miami, FL; Pittsburgh, PA; Baltimore, MD; Minneapolis- St.Paul, MN; Atlanta, GA; Denver-Boulder, CO; Seattle-Everett, WA; Milwaukee, WI; Kansas City, MO; Phoenix, AZ; Indianapolis, IN; Sacramento, CA; Greensboro, NC; Charlotte, NC; and Raleigh-Durham, NC; San Diego, CA; Tampa-St. Petersburg, FL; and Portland, OR. After the conclusion of the IVDS auction, it came to the Commission's attention that the Commission's rules and other IVDS auction requirements might have been violated by some of the participants. Therefore, the Commission ordered an investigation of the conduct of the applicants in the auction to determine whether misconduct had occurred. One target of the investigation was Commercial Realty. As a result of the investigation, the Commission determined that Commercial Realty willfully misrepresented its financial status to the Commission. A forfeiture of $10,000 for each of the 20 markets involved ($200,000) was assessed for this violation. Commercial Realty is a for-profit company incorporated in Florida on September 10, 1984. At that time, its sole director, President and Registered Agent was James C. Hartley. On February 17, 1984, Hartley's wife, Teresa Hartley, purchased all the outstanding shares of stock in Commercial Realty from a third party for $500. On April 15, 1994, she amended the corporation's bylaws to provide for a board of directors consisting solely of herself. The Commission's investigation revealed that James Hartley controlled the company and continued to make all the business decisions, including the decision to default on the down payments. Therefore, the Commission found that Commercial Realty had improperly claimed bidding credits as a woman-owned business and assessed a forfeiture of $10,000 for each of the 17 times it claimed the credit ($170,000). The investigation also revealed that Mr. Hartley engaged in prohibited discussions, or other communications, with another bidder on at least two occasions before down payments were due. The Commission assessed a forfeiture of $10,000 for each violation ($20,000). Action by the Commission February 15, 1995, by Notice of Apparent Liability for Forfeiture (FCC 95-58).

Siegman) Subject: Typical Rates for Campus Phone Systems Date: 17 Feb 1995 04:24:28 GMT Organization: Leland Stanford Junior University University phone service fed into my campus office to handle a fax machine (for what would be a very small amount of traffic) led me to make the mistake of asking how much this would cost. The answer: $155 initial installation fee, $36/month for the line. Page A-5 of the Pac Bell phone book says that in any of the surrounding communities I can get dial tone for a $35 installation fee and $4.45/month for all-metered service or $8.45/month for unlimited local calling. This is partly an apples vs oranges comparison, because the campus system (a Northern Telecom switch, I believe) gives me on-campus extension dialing, a voice mail service, and various other stuff, but I'm still curious: what does phone service in other universities or similar large organizations cost? If Stanford out-sourced the operation of its campus phone systme to some private contractor, could we expect significantly lower rates? Is the Centrex type campus service really worth four times what the phone company could give me? Any comments or data points appreciated -- siegman@ee.stanford.edu ------------------------------ From: B. Z.

I didn't see this here, but I did see it described in one of the electronic hobby magazines MANY years ago. At that time a common failure mode for NiCd batteries was an internal short. A heavy discharge through the battery might clear the short and give the battery some more life. You charge a capacitor (I don't remember exact values, probably several hundred micro-Farads at ten or more volts) and discharge it though the cell in the forward direction (to prevent reversing the cell) and hope for the best. > Has anyone out there tried this technique with success? Could you tell > me how this is done, what precautions I should take when doing this, > prognosis for success, etc? I played with it a little. It seemed to bring some cells back to life for a while, but they're never really all that reliable afterwards. And it won't fix all problems or restore all cells. If you happend to have the parts on hand, you have little to lose by trying it, but don't expect much. Also keep in mind that the internal construction of NiCd cells differs a lot between manufactuers, and new cells are much different than old cells when the article was written. Standard precautions to prevent electrocuting yourself would apply. In addition, heavily overloading a NiCd cell could cause it to leak or explode. B. Z. Lederman. My personal opinions. [TELECOM Digest Editor's Note: You know, BZ, I wish I'd had someone like you around a number of years ago to remind me about 'standard precautions' when this fellow brought me an old television set he wanted converted into a black and white monitor for one of his old Apple ][ computers. That's easy enough, you just get in there and feed the picture tube from the composite video out of the computer. You cut the RF part of the television out altogether. Since it isn't *quite* as good as an actual monitor or a terminal screen -- the resolution is a little lacking -- you can do a few things to tidy up the screen a little. My favorite is to wrap a piece of tin foil around the picture tube, from about the yoke on downward. It is hard to explain, but it keeps the picture looking sharper. Of course you adjust the yoke a little as well; it will work nicely as a poor man's video monitor, espcially since you can get used television sets out of garbage dumpsters for free if you walk down any alley the night before the village garbage pickup on that block the next day. The plug breaks off or a knob gets broken, the people don't know what to do so they junk the whole thing and go to Walmart and buy a new one. Well! You know and I know that old television sets hang on to their juice for quite a while (sometimes a week!) after they are unplugged. My favorite demonstration for the neighborhood kids years ago used to be to unplug the radio or television, take the case off and present a little show where I took my very long handled screw-driver, went in there from one of those big capacitors to the chassis ground and watch the fireworks. Boom! Boom! Boom! Sparks would fly and that old chassis would sit there and argue with you. Once it quit doing that, *then* you knew it was safe to get in there with your hands and touch anything you wanted. So the guy brings his television over to my place. I unscrew the case and take it off. We are sitting there talking and I *forgot to discharge those caps* first. Inside I go with my hands; start pulling a couple of wires to be stripped and connected elsewhere. Boom! I took that load myself and it knocked me on my keister! Afterward it was funny, but it wasn't at the time. Lesson for today: high voltage can kill. Even car batteries, when properly juiced up and you standing in a puddle of snow or slush trying to tinker with your car engine can give you quite a rude shock. Know what you are doing when you tamper with electricity -- of any sort, and especially DC (direct current -- that stuff *is* potent) or just don't do it. You've been advised.

NiCads form memory blocks mainly because a heavy crystal layer builds up at a certain point in the battery. The crystals at this level get very large, and wont disolve to produce the electricity, hence the memory effect. Also, if these crystals get big enough, they form spikes that can peirce the battery casing causing a short circuit in one or more cells in the battery. We have about 120 portable VHF 2-way radios in service at the resort, and they are constantly being mischarged. This past year we purchased a CADEX battery analyzer for about $1700 that took care of our problems completely. Although the unit is a little expensive, we would throw out about $600 worth of "good" batteries a year. The unit will analyze the battery, and discharge it to BELOW one volt per cell. This is extremely effective in breaking down those large crystal growths. With a simple battery maintenance program in place, all of the batterie come in for conditioning about four times a year, and end up lasting a lot longer. You also need to be careful not to "cook' the batteries when charging them. The CADEX monitors this for you also by keeping the eye on the temperature of the cells. If you don't want to invest $1700, most local 2-way shops have this or a similar unit, and will be willing to recondition your battery at a fraction of the cost of a new one. Personally, my Makita Drill battery was giving me about 15 minutes of service before dying out. The CADEX brought it from 27% capacity, to 104%. It's like a brand new battery now, and you can be sure it gets regular reconditioning. If you would like to call me at my office, I can give any one who is interested the specifications on the CADEX system, and their 1-800 number.

PAT] I find it interesting that he is actually prevented from using a telephone, even for voice calls, while in jail. He used a cellular phone for his "dialin", so there would be no endloop to trace, although eventually cellular triangulation was used to locate him. One more delay point, but only a good one if he moved occasionally, which he did not. My wife expressed the typical layman's amazement at the ability to do some of these things, but it is basically a violation of trust. Telco and Internet can only be broken because they are easy to use. He is slime. He is sleaze. Although I can't justify wanting to see him hang, I certainly hope he is prevented from touching a telephone for quite a long while. At least he has proven himself beyond trust as an "analyst". He won't be landing a fat job protecting us from himself ;-( Clarence A Dold - dold@rahul.net - Pope Valley & Napa CA. [TELECOM Digest Editor's Note: The last word I got on his telephone call privileges was that at his request in court last week, he was granted permission to use the phone to call three people only: his attorney, his mother and his grandmother. The magistrate ordered prison officials to allow Mitnick to make a 'reasonable number of calls when he wishes to do so' to those three persons, whose telephone numbers are part of the order. Prison officials are required to (1) establish the connection to those numbers -- not allow Mitnick to do it; and (2) to 'periodically in the course of his conversations on the phone' monitor the line, listening to insure no 'computer or modem noises' are heard. In order that Mitnick can have his right to speak confidentially with his attorney, they must tell him when they wish to listen on the line for a few seconds at a time so that he and his attorney can remain silent during that interval if he wishes to do so. The court further admonished grandma not to use call- forwarding, three-way calling or any other 'extension of the connection' when speaking to Kevin; likewise his mother was admonished. I'm afraid this time its looking pretty grim for Kevin; if he gets out of this with another period of probation instead of a long time in prison, my advice would be he'd better start blowing his nose with a silk handkerchief.

He will probably get around 30 years of prison, but will probably get out in about five years. I actually wish he would make bail; he would definitly skip the country, or attempt it. He is a brilliant person, but took things to extremes and didn't get on with his life. I hope the best for him. CM [TELECOM Digest Editor's Note: There is no possibility of making bail since the court refused to set bail. Actually, in most federal courts it seems, things go one of two ways: either you are denied bail and held pending trial, or you are released on your own 'recognizance', or admission of the court's jurisdiction. Federal courts hardly ever ask for money as bond; not the way the state courts do. They can, but they seem to figure either you are not a danger to the community and smart enough to stick around (after all, where would you run to?) or you are likely to be a hassle so they keep you. If you have a family to support, employment and an employer who is *knowlegeable of the circumstances but willing to keep you on and help you* then most federal courts just let you go pending trial, and you report to a parole/probation officer in the meantime.

I have the oddest feeling that I know who this guy is ... sort of. Emmanuel Goldstein, of 2600 magazine, does a weekly telephone-oriented radio show on WBAI in New York every Wednesday at 10pm. A few months back the topic turned to exchange names (MUrray Hill, LAckawanna, DEcatur, etc.). Within minutes, this extremely literate sounding guy called in and started rattling off dozens of exchange names and their histories. In the following weeks this guy has called with other telephone related trivia, and with every call he displays an almost unnerving amount of both knowledge and curiousity about things telephonic. I believe he's mentioned that he has a 700 number, and/or an 800 number, and/or a 500 number. I also recall that he mentioned he lives in Brooklyn! Without getting too dramatic, whenever I hear him call I get an almost twilight zone-feeling of eerieness about him. I wouldn't be at all surprised if this was the guy. Call WBAI in New York (call directory assistance for the number) Wednesday nights at 10p Eastern and maybe Emmanuel can point you in the right direction, or even get the guy to call. I hope that helps, but I'm not sure if I hope I'm right -- or wrong. Please keep me posted. Mike [TELECOM Digest Editor's Note: When I talked to this fellow he was quite literate; and everything I challenged him on (how he knew about a site in California; how he knew the way to contact site admins here) he had an answer for. I sort of tested him also on his knowledge of his immediate neighborhood from a very large, detailed map I have of Brooklyn/Queens. He has to be around there; he knew much more than even a typical resident on things like the *exact* boundary between Brooklyn and Queens. He could say without hesitation that the boundary runs down the middle of the Newtown River (Creek?) and 'when you get to Flushing and Metropolitan Avenues, at the Onderdonk House then a few yards southwest of there ends Queens and starts Brooklyn then it runs southeast on the southwest side of the street for several blocks and where Myrtle Avenue crosses the boundary between Brooklyn and Queens the boundary dips to the southwest and runs a half block down Myrtle Street then it goes southeast again until it reaches Bushwick and Highland Boulevard then it turns and goes northeast on the north side of Highland, more or less through the middle of Highland Park then when that line going straight northeast reaches the southwest corner of the Forest Park Golf Club it then drops and goes almost straight south crossing Jamaica Avenue at that point and Etna Street then a couple blocks later, Atlantic Avenue. As soon as it crosses Atlantic Avenue it runs northeast on the south side of Atlantic Avenue for about a block then it goes southeast again and crosses Conduit Boulevard at the intersection of Pitkin Avenue and a couple blocks later it reaches Linden Boulevard where it turns and runs almost straight east for a couple blocks with one side of Linden in Brooklyn and the other side in Queens. Then just before Linden reaches Conduit it turns south/southeast again for half a mile, southwest for half a mile, south for a couple blocks, southwest for a couple more blocks then it makes a sharp angle going southeast for about a block and crosses Shore Parkway then out into the water ... ' all that in more or less one long sentence. But even though at one point he said to me he was alone there, this was not true: Playing along with him a bit further, I remarked that he must be in the 77th police district ... that rotten hell hole that ten years ago had to be totally cleaned out with a special prosecutor appointed to investigate the police, etc. (I know the 77th is north of him a few miles, up in Bed-Stuy.) He thinks for a minute and I hear him ask someone 'is this the 77th police district' and a second or two later he is back and says no it is not. (I forget what number he said it was.) I did not comment on the fact that he spoke to someone else after earlier telling me no one was there ... that he was home alone just doing some research. I suppose a retired cab driver in Brooklyn would know every inch of the boundary line with Queens, what streets it ran down, etc. I still don't have an actual name, but I am sure by now EG has seen this and probably noted if it is the same person or not.

I'd be willing to bet that this guy was one of the listeners to an FM radio show called "Off the Hook" which is broadcast Wednesdays from 10 to 11 pm over listener-sponsored WBAI in New York City on 99.5 MHz. The show is hosted and produced by "Emanuel Goldstein," publisher of 2600 Magazine, and the alt.2600 newsgroup, and is co-hosted by "Phibre Optik," that is except during the year he was in the federal pokey for a hacking-related offense. Actually, that's not altogether true. Phibre did manage to co-host several shows even *while* he was in the federal pokey. Yes, prison authorities do keep an approved list of numbers each inmate is permitted to dial on the prison COCOTs, and no they probably would *not* have approved WBAI's studio number. But they do not seem to have ever heard of a feature called Call Forwarding. But I digress ... "Off the Hook" did a segment on 500 numbers on the show one night, right around the time the list was published (late in Volume 14) and mentioned the list, and the TELECOM Digest issue by number, on the air. They gave the mit.edu newsgroup address as well. The show takes listener phone calls during roughly the second half hour, and one regular caller is a gent who says he's from Brooklyn, near Flatbush Avenue. Usually (and mysteriously) he's more often than not the first caller on the line each week, independent of which line they answer first. It's an admitted long-shot, but this may just be your guy. If it is, then from the sound of him he's a garden variety phone phreak or telecom junkie with time on his hands. As such, he's likely to know all about ANI, NPA 700, Belcore, and similar things the general public has never heard of, since they're common topics of conversation on the show. He's also likely to have a 700 number, a half dozen 800 numbers (some of them even his ) but may be quite truthful when he says he knows little about computers. If he gets to be first in line for the call-in segment the way I suspect he does, he'd need seven to ten POTS lines at his house, and some phones with redial buttons, since NYNEX now times out any don't-answer calls after 25 rings or so. If this is your guy, or if he fits this general pattern, then he's probably harmless enough. (Until he learns enough about the Internet to be dangerous.)

These terms are most certainly NOT relative to T1 lines!!! Ther refer to analog telephone line "start" signals that indicate to the CO (central office) that an off-hook condition exists and dial tone services are required. Loop start means that both battery and ground leads are present and that ground, therefore, is supplied by the CO. Ground start means that a local (local to the off-hook instrument) ground is used and represents a "single-lead" subscriber line. Ground start lines were and are not often used since the ground resistance between the subscriber and the CO is unpredictable at best and conductor pairs (rather than single copper wires) have been in use for a long time now. Wink start indicates a reversal of battery and ground, typically for less than 500 milliseconds, and is used for TRUNK, not LINE signalling. I won't waste bandwith correcting misconceptions about T1: buy a little book and read it. ------------------------------ From: nagle@netcom.com (John Nagle) Subject: Re: What is Loop Start?

On normal analog lines, going off-hook can indicate either an intent to originate a call or to answer one. When a subscriber goes off-hook with intent to originate but actually answers an incoming call, the situation called "glare" has occured. This is a big problem for heavily-used lines used for both incoming and outgoing calls, especially when the lines are terminated in a PBX, fax, or modem. So there needs to be some way to distinguish off-hook for originate from off-hook for answer, and that's what "ground start" is about. One lead is grounded at off-hook time to make the distinction. Ground start is usually used for PBX lines, but any line can be configured as ground start with most modern CO switches. Some modems (not many) will interface to a ground start line. Callback security devices need a ground start line to prevent glare-type spoofing. John Nagle ------------------------------ From: noah@rain.org (Matt Noah) Subject: Re: What is Loop Start?

These are ANALOG line signaling schemes. Loop Start lines are those associated almost exclusively with your POTS phone service at home. These same lines may carry additional CO features. The term Loop originates, I believe, from the fact that when a phone set went off-hook, a loop current flowed, signaling a line seizure to the CO. Ground Start lines were the old pay-phone style lines and analog CO-PBX signling lines. Ground Start was developed, I believe, to solve the problem of GLARE on phone lines. Wink Start has meaning both for E&M and Loop/Ground Start signaling. In basic terms, a "wink" is generated when the attached equipment is ready to accept dial digits. If a wink does not appear, there are no dial registers available to accept your digits! It sounds as if you need a good book on signaling. I suggest a trip to your local technical bookstore.

I was reading about Pat's cigarette 'habit' a few posts back, and I just watched 20/20's piece about people being addicted to caffiene. They used a more acceptable name for it: dependency syndrome, or something like that. Reminds me of the lady that lived in my apartments when I was manager. She had to go on permanent disability a few years before she retired. She had emphysema, but she still smoked. One time she forgot and lit up with the oxygen tubes still in her nose. Have you ever seen what happens to a fire when it's exposed to pure oxygen? Well, she learned that she couldn't do _that_ anymore. She was dependent on the oxygen, and if she wanted to go anywhere she had to drag along the portable unit, so she often just didn't go. One time she asked me to get her a pack of cigarettes from the store. I said that I didn't want to contribute to her emphysema problem by buying her them. She went off in a huff, saying that she would never ask me to buy her cigarettes again. Fine, I said. The next day, she asked if I would go to the store for her, for guess what. A few years later, the next door neighbor found her on the floor, face down, cold and stiff. No doubt, the smoking contributed to her shortened life. Cigarettes are indeed a powerful addiction. BTW, one of the people that they showed on 20/20 was a lady addicted to Mountain Dew.

Overall, I find this service to be a really good idea; I hope it will eventually have all the bugs worked out. Current problems: Voice quality isn't as good as standard AT&T calls. I notice a distinct drop in volume as I am connected to the True Connections answering unit. Using the call sequencing feature, I cannot get consistent results regarding the number of rings. As a caller, I hear "ringing" immediately when each sequence number is tried. But at the remote end, the telephone may not start ringing for several seconds. This is particularly a problem with my cellular telephone, which may take varying lengths of time to start ringing, depending on whether I am in my home area or not. I currently have my sequencing set to a small enough number of rings so that my office voice mail does not answer (so I can go sequence to the next number), but that results in my cellular phone ringing only once, which isn't always enough time to answer it. I think the only practical solution will be for us to be able to program a different number of rings with each sequence number. AT&T is returning supervision on all 0+500 calls, even when used to modify forwarding. I think AT&T should be returning supervision only on 0+500 calls when they connect to voice mail or are used to dial home (or another number). Purely administrative calls should not return supervision. My voice mailbox has a different mailbox number and password than my 500 number itself. This means I have to remember four different numbers to retrieve my voice mail. I would appreciate being able to get voicemail by just entering my 0+500 number and master PIN, then following the menu. Beeper notification isn't working yet, which makes voice mail somewhat awkward. When will this service be working? Feature requests: I would like to ask for the following features to be considered: Allow designation of special numbers the way *H (home) can be designated. For example: *C (cellular) *O (office) *P (pager) This would speed up both entry of sequence lists, and the reading back of sequence lists. Allow me to have a voice greeting (ten seconds) played as soon as a caller rings my number. I could say something like: "Hi, this is John. Please wait for connection to my current phone; if there is no answer, I'll be back on to take a message." Allow callers direct access to beeper service. Callers could press a key to stop ringing and connect directly to my beeper service. When a sequence number is busy, offer the caller a choice of trying the next number, going direct to voice mail, or trying again later. To make TrueConnections truly useful in the future, local calling should become very inexpensive. Right now, my local callers are reluctant to call my 500 number instead of a local number, because of the cost. With SS7, it would be possible for AT&T to direct the local phone company to re-route the call locally, rather than tying up AT&T circuits. As a customer, I'd be happy to pay a nominal fee (10 cents?) for such a re-routing, to save my caller per-minute charges. Since AT&T switching would be tied up for only a few seconds, the cost to AT&T would be minimal. Expanding TrueConnections in this way should allow many more customers to consider the service. ===================== [TELECOM Digest Editor's Note: Although I can understand how some of you feel about the 0-500 supervision issue, I have to take exception. Why should instructing a computer where to send your calls be any different than instructing your secretary or a co-worker where to send them? If you were using the method which has worked well for many years of calling your office and saying to the receptionist, "I will be over at client X for a couple of hours if anyone calls ...", would you object to paying for the call to your receptionist/secretary to give those instructions? In the case of 500 service, you are using AT&T as your receptionist/secretary/ message taker. Should AT&T and the interim telcos/celcos have to work for free? Your secretary does not work for free. I could understand having no supervision until a valid pin number was entered or a calling card number; but do you really think you should get the entire administrative process for free?

Protect your advertising and branding investments in your 800 numbers. Protect your brands and trademarks. Protect your business interests. If you don't, no one will. J. Oppenheimer, Producer@Pipeline.com Interactive CallBrand(TM) [TELECOM Digest Editor's Note: The only thing is, the telephone-using *public* has to be to some extent responsible for knowing what and where they are dialing. {Chicago Tribune} columnist Mike Royko has complained several times in the past about how his internal centrex number at the newspaper is the same as a very commonly used number by AT&T for customer service, minus the 1-800 on the front. Idiots galore trying to complain to AT&T about something or other -- after all these years -- still do not understand they must dial 1-800 first, so if they are in area 312 they get his private unlisted centrex number instead. And you know what he wants? He wants AT&T to change *their number* -- so that *he* won't get their calls. How do you accomodate idiots and fools short of stopping the world and letting everyone get off? Do you propose that when the 800 number supply is exhausted we just quit having any more? Do you propose that international commerce and trade be handicapped by having no uniform way to dial around the world with the charges reversed to the called party automatically? You use FLOWERS as an example, and apparently would restrict the use of 356-9377 where any other 'toll-free' numbering scheme is concerned because the Americans got it first and want to protect their brand name. That is all well and good, but 1-800-FLOWERS is not the same as 011-800-FLOWERS or 1-888-FLOWERS. Needless to say, its not the same as any local area code plus 356-9377, and yet day after day that number gets calls for FLOWERS by people who forgot the 1-800. There is a practical limit to how much can be done to idiot-proof the phone network. You say its okay to have things like 011-800 and 1-888 as long as the existing American 800 users can have their numbers grandfathered, or held out of use under the new codes? Well that would put us right back where we are now, with an increasingly limited supply of available numbers. Or are you suggesting that only the 'big' 800 users get that protection, and the rest of us with 800 numbers can live with the nuisance that the corporate clients you represent don't wish to tolerate, i.e. 'customer confusion' and having to pay for calls which generated no business, etc? This reminds me of the airline a few years ago which misprinted its schedule book -- thousands of copies distributed -- and gave out the number of some hapless individual in error instead. When he called to complain, they told him to change *his* phone number. When they later found out he was getting rather rude with persistent callers who kept telling him he was a liar and that they *knew* they had reached the airline, then the airline tried to sue him for force him to change his number so that their customers would not be confused. Never once did it occur to them to correct their own error and reprint their booklet. You may not recall, but the same kind of arguments you are presenting here came up twenty or more years ago as AT&T began major expansions of 800 service as it was configured back then. Relatively few companies had 800 service in the early 1970's, and those who did often times had words made out of the four digit suffixes. Then AT&T opened up a bunch of new prefixes and changed the configuration on some already being used and suddenly the same words showed up attached to other 800 prefixes in other parts of the country. "If I have 800-xxx-FOOD you can't let him have 800-yyy-FOOD; too many people will get us confused." That's life, sorry. You need to educate your customers *how* to place the call, what more can I say?

Steve cogorno@netcom.com NETCOM HELPS PROTECT THE INTERNET - A Letter from CEO Bob Rieger to Our Customers - I know many of you are interested in NETCOM's involvement with the arrest of Kevin Mitnick, and how this may impact you, if at all, as a NETCOM subscriber. First, let me supply a chronology of events: 1. In a routine security check, NETCOM discovered a misappropriated file. As a result, we began an investigation to trace what appeared to be a security breach. 2. At about the same time, the WELL (a small Sausalito-based on-line provider) was investigating an account with an unexpectedly large amount of disk usage. In the course of this investigation, they discovered suspicious material which included items believed illicitly obtained from well-known network security expert Tsutomu Shimomura's computer. Mr. Shimomura performed network monitoring at the WELL, and determined that the account was being accessed from a number of sites, including NETCOM. 3. The WELL contacted NETCOM for assistance in tracking the source of the security breach. 4. A day or two later, the FBI contacted NETCOM and requested NETCOM's active involvement in the broadening investigation of the suspicious activities at the WELL. 5. NETCOM caucused with representatives of the WELL, the FBI, the U.S. Attorney's Office, Mr. Shimomura, and Julia Menapace (an independent computer consultant and associate of Mr. Shimomura). 6. Following the conversation, it was decided that the best vantage point for further tracking of these activities was NETCOM's Network Operations Center. 7. NETCOM operations staff joined their efforts with Mr. Shimomura and his associates to trace the suspect intrusions to a particular telephone modem in NETCOM's Raleigh, N.C. site. 8. At that point, the U.S. Justice Department subpoenaed the local telephone carrier for records of dial-ins at specific times to this modem. It became apparent that the telephone company's switch equipment had been compromised, so that these records could not be obtained. However, the Justice Department found another method for making a match. 9. With this information, the Justice Department knew the approximate location of the originating call. 10. Mr. Shimomura flew to Raleigh and used cellular tracking equipment to locate the apartment building the calls were coming from. Eventually, the calls were traced to an individual apartment, and Mr. Mitnick was arrested. ------------------------------ Date: Mon, 20 Feb 1995 18:59:06 +0000 From: evan champion Subject: 500 Service in Canada Organization: Bell Northern Research Is 500 service beeing offered by Bell Canada yet (or will it be offered in the future), and what costs should I expect for making use of 500 service if and when it is available here?

Splitting the rate base, an important element of the CRTC's regulatory review decision issued last September, means assigning the company's costs and revenues to two distinct segments of our business - competitive and utility - using the CRTC-approved Phase III costing methodology. On the utility side, the CRTC would continue to regulate under the traditional rate base, rate of return regulation until January 1998 (when price caps are scheduled to be introduced). On the competitive side, we sink or swim on our own. Competitive areas of our business will no longer be part of the regulated rate base, and there will be no predetermined level of profitability associated with competitive service revenues. Unlike the other telephone companies, Bell did not include a financial forecast for 1995 as part of this filing, but anticipates doing so by March 20. The company's new management team is in the process of establishing a specific forecast for 1995 as part of a three-year transition plan. The January filing was the initial step in preparation for a public hearing to be held beginning May 8, in Hull, Quebec. The proceeding will also address such issues as contribution, rate rebalancing, and investment in the Beacon Initiative, as well as Canada/ U.S. cost comparisons in the delivery of long distance services. The public hearing is expected to last about eight weeks. -------------------------- David Leibold -+- dleibold@gvc.com -+- aa070@freenet.toronto.on.ca ------------------------------ Date: Mon, 20 Feb 95 12:38:24 CST From: leslie_smith@wiltel.com Subject: New RITIM Working Papers Dear TELECOM Digest, WilTel is pleased to announce the addition of new RITIM working pages to our Telecom Library.

What was, in myu opinion the best phone company in North America, has let me down. The problem? Bell Canada has never heard of 500 service. A quick call to Pat's number using both 1- and 0- gave me a "bad number" message. So, I got online with a Bell Canada operator, and she told me "sorry, I don't know of the 500 area code". I explained what the service was, and she said that she'd be glad to pass me on to the business office. I subsequently talked to Terry at the business office, and explained the deal. He called (while I waited) the product lines for Bell, and all the others he could think of, all to no avail. Terry has subsequently promised me to get back to me on the problem, and try to solve the missing NPA. Unfortunatly, Terry's going away on vacation for two weeks, so he'll continue the investigation after- ward. I politely suggested that he refer the problem to someone else while he was gone, but he said "I think I know what you are talking about, and I don't think I could explain it easily to someone else" (PARAPHRASE). Oh well. Terry will call me back with the results. I called 1-800-CALLATT; they didn't know what 500 was about; until I persisted. He can't connect me though.

Does this vary from state to state? Are the criteria mandated by the state public service commission? richard.palmer@palmer.com [TELECOM Digest Editor's Note: Generally if the street address where service is being installed is known to be an address where business is conducted (i.e. a store front, an office building, etc) then business service is required there *unless the subscriber can prove that the address is used exclusively as a residence*. A listing or lack of same in the directory (non-pub service) is of no consideration since many businesses do have non-pub lines. If the street address is known to be residential, then residential service is offered to the customer unless the customer states that the phone will be used primarily for business-related conversations *or* if the subscriber requests a directory listing in a business (or shall we say non-strictly residential, in order to include schools, churches, organizations, etc) name. Business and residential service can be mixed at an address which is residential in nature but residence service cannot be mixed with business service at an address which is commercial in nature. That is, you can have business service in your home if desired, but you may not have residence service in your business, *even if you live there, for instance in the back room of the store, etc*. Requests for entries in the telephone book of a business nature always require business service. Furthermore, if the requested entry appears to telco to have been fabricated or devised only for the purpose of manipulating the position of the listing in the directory, then telco can require proof that such entry is in fact a name under which the business is known, for example by seeing copies of incorporation papers or business license documents. Since listings are sorted in strict alphabetical order with duplications further sorted in alpha order by street name and with continued duplications further sorted in numerical order by number on the street (in other words, John A. Smith at 1234 Main Street would appear ahead of John A. Smith at 2345 Main Street) and remaining duplications sorted by phone number (so that two instances of John A. Smith at 1234 Main Street would appear with the one whose number was 123-4567 listed ahead of the one whose number was 123-4579), should a subscriber choose to be listed simply as 'A' then telco has the right to demand proof of such a name. Likewise any residential or business listing demanded where the name would otherwise be an offensive word can be challenged. ("Are you certain your name is Mr. Fu-k?").

From: Mikko Usvalehto Date: Mon, 20 Feb 95 17:40:01 +0200 Here in Helsinki University of Technology we are discussing what is the best way to coordinate telecom education in national level. Telecom business environment (both for operators and equipment manufacturers) is turbulent and technology competence needs of the telecom companies changes rapidly. Universities and institutes of technology have difficulties to follow the changes in business and also difficulties to provide education and continuing education, which satisfies companies' needs. We are interested in to know more about how telecom education is organised in different countries and is there any national strategies for telecom education ? If you have information on how telecom education has been organised in your country, then please contact: mikko.usvalehto@hut.fi Mikko Usvalehto Helsinki University of Technology, FINLAND ------------------------------ From: jypeng@netcom.com (Jian Yuan Peng) Subject: Help! - Vertex, DID or ISDN For My Phone Services Organization: NETCOM On-line Communication Services (408 261-4700 guest) Date: Mon, 20 Feb 1995 19:20:53 GMT Hi, Can you educate me about my question? This my first time to setup a telephone services, I have the following requirements: I want to setup three service lines and one support line. the service lines are 800 numbers (one 800 number from MCI). I want to accept three customers at same time. We plan to expand up to eight service lines in the future. For examples, If first customer calls in, then line one will answer. If other customers call in at the same time, when line one is busy, line two will answer. Same as line three, if line two is busy. The support line is not the 800 number. On that, the caller pays the toll. I have asked the hardware ventor, software ventor, and Pacbell about what kind of system I plan to setup. They told me different answers. Hardware ventor told me I need a DID system. Software vendor told me that I need a vertex system form my local telephone company. The Pacbell person told me (she recommended me) that I should rent a ISDN line. It seems to me that one of DID, Vertex or ISDN will work for me. The MCI told me they can broadcast the incoming call to all of three lines (all of them will ring as the same time.) if I want. I was so confused by all of them! Can you tell me what is difference between them? Can I extend to eight lines system later? Which is the lower cost? I also look into further, whether we need a T1 line (up to 24 lines) in two years later. Can we move smoothly from this current setup to 24 lines later? Any recommend- ations? Thank you for your information. Jian Yuan Peng jypeng@netcom.COM 650 Castro Street, Suite 120-265, Mountain View, CA94041 [TELECOM Digest Editor's Note: Oh, my goodness, my goodness. They are all going to sell you and oversell you. Forget every bit of what they told you and let's start over. Go to PacBell and say one thing: "I want four lines. Three are to be in a hunt group where the first hunts the second then the third. I want a fourth line which stands alone, not in the hunt group." Period. That's all you ask for. Do whatever they say or request in the way of credit requirements to get the lines installed and operating. As soon as the lines are installed -- and earlier, if you can get the number for the main line, and are sure it will be correct -- then you call up MCI -- if that's your pleasure, but I could make other suggestions -- and you tell them "I want an 800 number, and I want it to be pointed to xxx-xxxx" (whatever the number is PacBell assigned you as the lead number in your group of three lines.) Period. That's all you say to them. When MCI turns on your 800 number and points it to the main number in your group of three lines, everything you wanted will be accomplished. If a second or third person calls your 800 number while it is in use then those calls will be directed -- just like the first one -- to your main listed number. When those overflow calls hit PacBell, the local telco will put them on your overflow hunt lines two and three. MCI does not need to know *how* you are handling those calls (that in reality they are going in your hunt group somewhere) nor does PacBell need to know (nor do they care) where the calls are coming from, just that when they get them they put them on line one, then two and three as needed. You will want to make sure that your MCI 800 number has the capability of handling more than one inbound call at a time; there are a few out there that literally require you to have an '800 hunt group' with the inherent extra monthly service charges for each line, but most do not. Their switches are capable of taking 800 calls en-masse for you as long as you have somewhere to terminate them on your end. Meantime, that single line not part of the hunt group is sitting there and taking calls. You advertise its regular number so the caller has to dial that and pay for it. Next year if your business is still around and prospering and you need another five lines to make eight in total you call PacBell again and you say "I want five more lines in my existing hunt group." Period. Don't get them all confused using terms like T-1 and vertex and DID. That way they won't get you confused with their conflicting (and frankly, sales- oriented) answers. You don't need DID and a T-1 ... what are you running, the phone room for the Shopping Channel?

It is a valuable and worthwhile addition. Coverage of the topic is very broad-ranging, although it is not, perhaps, complete. The material is very practical, with lists of do's and don'ts, summaries, and question-and-answer sections. Rose has a professional grasp of humour, and it is used extensively and effectively throughout. The book is not without problems. There is a shortage of explanation of the "why" on various topics. There is a chapter on how flames start (and a pretty good one) -- but not until chapter six. Rose recommends against the spread of "dying child" letters--but doesn't explain the situation behind the Craig Shergold stories, nor the related "Neiman-Marcus cookie" legend or the "FCC Modem Tax" rumours. He mentions the frequent administrative mis-posts on mailing lists, but not how to avoid doing them. Some specific recommendations are questionable. He suggests the use of abbreviations and "cyberese" (the acronyms of common phrases, like BTW for "by the way") as a means of keeping messages short. This is no longer considered good etiquette, as it is highly confusing to newcomers -- and oldtimers as well, in certain cases. (In fact, the book contradicts itself at this point, recommending both for and against abbreviations, on a single page.) (Some may also consider the repeated promotion of Kent's "The Complete Idiot's Guide to the Internet" (BKIDTINT.RVW) and "The Complete Idiot's Next Step on the Internet" (sorry, haven't seen it yet) almost to constitute "spamming" within this book, itself.) I definitely recommend this work for all Internet users, and particularly newcomers. I very much hope future editions will extend a work well begun. copyright Robert M.

It appears that no one on that network can give a definitive answer as to exactly how it works. So I am leaving a message here hoping (knowing) that someone will have the correct answers. Some of the questions we have regarding auto-registration on a cellular phone (system) are: 1) Does the individual phone transmit it's MIN/ESN pair on powerup after finding an appropriate control channel? 2) If indeed the phone transmits it's ID upon powerup, why is it apparently ignored by some systems (AirTouch in Los Angeles)? 3) What would be the typical amount of time between auto-registration requests on most cellular systems? (I know this varies on system usage, software, etc. but would like a "ballpark" number). 4) How exactly does the cellular system request an ID from each phone and keep it orderly? (IE..does it go by ESNs? How are collisions prevented from multiple phones? etc.) 5) How do cellular systems treat older phones (without auto-registration) when trying to ring them (phone call to phone)? I'm sure I've skipped a couple of obvious questions but if someone could enlighten me with answers to these questions, I would greatly appreciate it.

Questions: 1) Do you know of similar fraud in other networks? 2) What is done to try and prevent such fraud? 3) Has any telco implemented a pre-paid residential service? 4) If so, how does it work? Thanks, Please also email replies to : laakswk@telkom04.telkom.co.za Keith Laaks Email : laakswk@telkom04.telkom.co.za Tel : +27 12 311 1450 Fax : +27 12 311 3492 [TELECOM Digest Editor's Note: Do we know of other instances of toll fraud? Do we? Umm, yes, it is a very severe problem here in the USA. What you term 'prepaid residential service' we refer to as a 'security deposit', and/or payment in advance for the first month's charges. Generally the telcos in the USA accept the references of other telcos for the purpose of establishing service. If you've had service anywhere in the USA then your credit history as far as telco is concerned is available to other telcos for review. Of course, if you live in one area for most of your life and have service from the same phone company most of that time, then they have your record and know about both your ability and willingness to pay. New subscribers with no previous telco (somewhere) payment history are often asked to place an amount of money in escrow or on deposit with telco to cover the estimated billings for a month. After a year or so of good payment history, this money is refunded with interest or placed on your account against your current bill, as you wish. 'Payment in advance' is *not* a security deposit, and does not draw interest. It merely insures that your first month's bill is paid while telco evaluates your 'typical' or 'average' use. A third option used in some cases is called 'interim billing'. Although bills are tendered 12-13 times per year (most telcos bill monthly but some bill every 28 days), in what is known as cycle billing (a group of different customers each day, normally 22 billing cycles per month), for internal use only there is the 'interim billing' which is available to the collectors and credit representatives about two weeks after (or before) the bill mailed to the customer. If this interim billing shows a sudden dramatic increase in charges such as a large number of long distance calls or calls of a great time length causing your bill to exceed its normal balance by some large amount, then they will call you and ask for more money then; this depends on your status with them. If your bill becomes past due, again your status detirmines what action is taken. A new subscriber with a balance two months past due will most likely be cut. Longer subscribers with generally good credit will be allowed longer, etc. PAT] ------------------------------ From: mdouglas@sol.UVic.CA (Mark Douglas) Subject: Wanted: Cellular Channel Measurements Organization: University of Victoria, Victoria, BC, Canada Date: Mon, 20 Feb 95 02:04:23 GMT I am teaching a university course on mobile communications and am interested in the following data of the received signal at a cellular phone: 1. The signal envelope over time (Rayleigh/Rician) 2. The time delay response (showing delay spread). 3. The power spectrum (frequency domain) Real measured data would be ideal, but simulated data is fine as well.

It is related to the thread because auto batteries are part of schemes to revive NiCads. Electrocution from these may be possible (I heard of a case but have no certainty if it really happened), but is quite unlikely. Serious burns are not so uncommon. One should remove metal jewelery, including watch bands and rings when working around these batteries; they can deliver huge currents, enough to spot weld the jewelery, and heat it up to skin burning temperatures in a second or so. Though I have see warnings about this risk for years I did not know of a case until a friend got it wrong a couple months ago. He showed a deep burn around his finger where his wedding ring combined with a wrench to short over the battery terminals. He was lucky; the wound healed and except for the scar he will have gained; he knows very well about being careful next time and may be saved from removing the finger completely. Sincerely, Bob Mueller [TELECOM Digest Editor's Note: I still have a tiny little scar on my left arm (on the underside, a few inches up from my wrist) which I got from the night thirty years ago or so that I fell asleep at the switchboard. If you remember the old cord switchboards, you will recall the rows of cords with plugs on the end which sat in front of you. About 2 am after several slices of pizza and a quart of beer from earlier in the evening I was feeling drowsy. I had the common audible (buzzer) loud enough it would wake me up, so I folded my arms in front of me as I sat there and put my head down on my arms ... bingo, three minutes later I am out of it. Once before I had done this, and fell asleep with my foot on the buzzer cut off switch; the little button on the floor the operator could tap on to shut the buzzer off when desired ... ... but not this night. This night I would wake up if any calls came to the board which was unlikely ... this was a Friday night and the Sabbath, and the mostly elderly Jewish residents of the South Shore Country Club Apartments would be long tucked in their beds and asleep. South Shore Country Club had a four position manual cordboard; usually three operators on duty during the day and evening, and one overnight. On Friday night and Saturday all day usually one operator was sufficient since the more religious of the tenants in the apartment complex did *not* use the telephone for any reasons those days; nor did they use the elevator. Instead of calling downstairs to the switchboard to get someone at the front desk to come up and light their stove for the sabbath meal they felt it more appropriate to walk down ten flights of stairs to make that request, then walk back upstairs again. Since I am not Jewish, you see, I was under no obligation to observe their laws; I *could* ride the elevator upstairs, light their stove or turn the lights on and off, etc, then ride back downstairs. But I digress ... roomate and I had been out earlier that evening to celebrate something or other ... pizza and beer ... you know that combin- ation ... 11 pm and I have to go to work, running the board at the Country Club until 7 am. By 2 am everything *so* dead ... *so* quiet ... and as noted above I fell asleep. I slept maybe three hours, and about 5:30 am the little alarm clock goes off which means it is time to start making the first of the 'wakeup calls' to the tenants. My arm somehow during the night had gotten up against or on top of that row of plugs, and it laid there most of the night. A little red burn was on my skin where it had been on the tip of that plug all night. I thought it would eventually go away, and the redness went away the next day but the little scar where the direct current lingering in those cords burned my flesh a little never has. Finally, if you ever want to test a battery to see if there is still life in it and you don't have a battery tester, just put the contacts from the battery against the bottom of your tongue ... ...

Protesting the announcement of another 5600 layoffs, 1200 Bell-Atlantic employees in Pennsylvania wore T-shirts to work which graphically depicted themselves as Information Highway Roadkill. The layoffs were just the latest round of cutbacks at Bell-Atlantic, which have been matched by the elimination of jobs at the other giants of the telecommunications industry -- ATT, NYNEX, Northern Telecom -- supposedly the very places where new jobs are to be created with the information highway. In reality, the technology is enabling companies to extend their operations and enlarge their profits while reducing their workforce, and the pay and security of those who remain, by contracting out work to cheaper labor around the globe and by replacing people with machines. The very workers who are constructing the new information infrastructure are among the first to go, but not the only ones. The same fate is facing countless workers in manufacturing and service industries in the wake of the introduction of these new information technologies. What is most striking about the Bell-Atlantic episode is not just the provocative fashion statement of the workers, members of Communication Workers of America District 13. Rather, it was the company's exaggerated response. Bell Atlantic demanded that the workers remove the T-shirts and when they refused, their employer suspended them without pay. According to Vince Maison, president of the union, the employer suspended the employees out of expressed fear that their message would be seen by the public. Significantly, management was concerned about adverse publicity not just for Bell Atlantic but, more importantly, for the information highway itself. This was the first time the information highway was unambiguously linked with unemployment, by a union and workforce presumably best situated to reap its promised benefits. Apparently the company believed there was too much riding on the information highway bandwagon to allow this sober message to get around. But it did anyway. The (probably illegal) management action backfired. Rather than a few hundred customers catching a glimpse of the T-shirts during the course of the day's work, millions throughout North America saw them through the media coverage of the suspensions; within hours, the union was inundated with phone calls of support and orders for the T-shirts. The truth was out. By now probably everyone has heard of the information highway, as a result of the massive propaganda blitzkrieg of the last year. Announcements heralding the dawn of a new age emanate incessantly and insistently from every quarter. The media gush with the latest info highway traffic reports (but not the fatalities), all levels of government are daily pressured into diverting public monies into yet another private trough, every hi-tech firm, not to mention every hustler and con artist in the business and academic worlds is rushing to cash in on the manufactured hysteria. The aggressive assault on our senses is aimed at securing public support and subsidy for the construction of the new commercial, infrastructure. Its message, which has become the mind-numbing multinational mantra, is simple and direct: We have no other choice. Our very survival, it is alleged as individuals, a national, a society, depend upon this urgent development. Those without it will be left behind in the global competition. And those with it? A recent "Futurescape" advertisement supplement to the Globe and Mail by Rogers Cantel and Bell Canada warned that the information highway "raises the ante in competition. If we don't act, Canada and Canadian companies will be left behind.... the information highway is not a luxury technology for the rich. It is the way of the future. And those who do not get on the highway will not have any way of reaching their ultimate destination." And what exactly is the destiny advanced by the information highway? Ask the Bell-Atlantic employees. The propaganda never mentions the roadkill, of course, but that is the future for many. Most people in Canada instinctively seem to know this already. According to a 1993 Gallup poll, 41% of those currently employed believe they will lose their jobs. But, despite this intuition, people have been terrorized into a hapless fatalism. It's inevitable. Or else they have been seduced by the exciting array of new tools and diversions: home-shopping, home-videos, home-learning, home-entertainment, home-communication. The operative word is home, because home is where people without jobs are -- if they still have a home. The focus is on leisure, because there will be a lot more of it, in the form of mass unemployment. (Some lucky few will get home-work, as their job takes over their home in the sweatshops of the future). This is where we are headed on the information highway. To see where we are headed requires no voodoo forecasting, futuristic speculation, much less federally-funded research. We just need to take a look at where we've been, and where we are. The returns are already in on the Information Age, and the information highway promises merely more of the same, at an accelerated pace. In the wake of the information revolution (now four decades old -- the term cybernetics and automation were coined in 1947). People are now working harder and longer (with compulsory overtime), under worsening working conditions with greater anxiety, stress, and accidents, with less skills, less security, less autonomy, less power (individually and collectively), less benefits, and less pay. Without question the technology has been developed and used to deskill and discipline the workforce in a global speed-up of unprecedented proportions. And those still working are the lucky ones. For the technology has been designed above all to displace. Structural (that is, permanent and systemic as opposed to cyclical) unemployment in Canada has increased with each decade of the information age. With the increasing deployment of so-called "labor-saving" technology (actually labor-cost saving) official average unemployment has jumped from 4% in the 1950's, 5.1% in the 1960's, 6.7% in the 1970's, and 9.3% in the 1980's, to 11% so far in the 1990's. These, of course, are the most conservative estimates (actual unemployment is closer to double these figures). Today we are in the midst of what is called a jobless recovery, symptomatic and symbolic of the new age. Output and profits rise without the jobs which used to go with them. Moreover, one fifth of those employed are only part-time or temporary employees, with little or no benefits beyond barely subsistence wages, and no security whatever. In 1993, an economist with the Canadian Manufacturers Association estimated that between 1989 and 1993, 200,000 manufacturing jobs were eliminated through the use of new technology -- another conservative estimate. And that was only in manufacturing, and before the latest wave of information highway technology, which will make past developments seem quaint in comparison. None of this has happened by accident. The technology was developed, typically at public expense, with precisely these ends in mind by government (notably military), finance, and business elites -- to shorten the chain of command and extend communications and control (the military origins of the Internet), to allow for instantaneous monitoring of money markets and funds transfer, and to enable manufacturers to extend the range of their operations in pursuit of cheaper and more compliant labor. Thus as the ranks of the permanently marginalized and impoverished swell, and the gap between rich and poor widens to 19th century dimensions, it is no mere coincidence that we see a greater concentration of military, political, financial, and corporate power than ever before in our history. In the hands of such self- serving elites -- and it is now more than ever in their hands -- the information highway, the latest incarnation of the information revolution, will only be used to compound the crime. Visions of democratization and popular empowerment via the net are dangerous delusions; whatever the gains, they are overwhelmingly overshadowed and more than nullified by the losses. As the computer screens brighten with promise for the few, the light at the end of the tunnel grows dimmer for the many. No doubt there has been some barely audible and guarded discussion if not yet debate about the social implications of the information highway focusing upon such issues as access, commercial vs. public control and privacy. There is also now a federal advisory commission on the information highway although it meets in secret without public access or scrutiny, doubtless to protect the proprietary interests of the companies that dominate its membership. But nowhere is there any mention of the truth about the information highway, which is mass unemployment. For decades we have silently subsidized the development of the very technologies which have been used to destroy our lives and livelihoods, and we are about to do it again, without debate, without any safeguards, without any guarantees. The calamity we now confront, as a consequence, rivals the upheaval of the first industrial revolution two centuries ago, with its untold human suffering. We are in for a struggle unlike anything any of us have ever seen before, as the Bell-Atlantic employees testify, and we must use any and all means at our disposal. It's time we came to our collective senses, while there is still time. We must insist that progress without people is not progress. At the very least, as a modest beginning, we pull the public plug on the Information Highway. [David Noble is a professor at York University and a historian of technology.

Previously, option #2 was to "Call Home", but is now "To place a call". I tried out the "Place-A-Call" feature and it worked (from the 312/708 area).

David Oehring david.l.oehring@att.com [TELECOM Digest Editor's Note: I tried it from here also now that you mentioned it, and mine is working also. That prompt 'to call a different number' also has a condition where you can call the override number if one is installed. The prompt does not mention it if one is not in place. I also get 'press 9 for other options' which includes the ability to change the number of times my phone will ring before the call is passed along to the next number on the reach list. Did you notice by the way that it never refers to your home number by their digits ... only by the phrase 'your home number'. If you enter #H she says you entered your home number .. if you punch in those digits instead, instead of reading back the digits to confirm as is done with other entries, she still says 'you entered your home number'. But when I entered my second line, she read back the digits, apparently not knowing that was also at home.

PAT] But there are several other ways to eavesdrop on cordless telephone conversations without using a scanner. One is to use another cordless telephone. Some of them can hear other channels without butting in on the conversation. Then there are wireless baby monitors and walkie-talkies, which can receive conversations easily. And these are just a few of the more common ways of doing this. Treat your cordless phone as if there were others listening all the time. Don't give out credit card numbers on the cordless phone. And don't say anything you might regret.

I recently have discovered my calls were being listended to both by a neighbor (who lives about an acre away) and by some kid down the street. The neighbor called to inform me that my telephone conversation was being broadcast over his kids baby monitor, one of those cute little wireless units that hangs on babies crib (glad I wasn't calling a 900 number). And the kid down the street? He was showing my kids how to use a transistor radio to listen in on our calls, and demonstrated by listening in on one of my calls.

While NYNEX/NY is offering free weekends until 7/31/95, BAMS/NJ is offering free OFF PEEK until 8/31/95! (It still makes me think about using my second NAM). I wonder, though, how BAMS gets away with charging a .04/minute landline charge when THEY ARE the wireline carrier.

Does NYNEX require a PIN for each call? When I had PIN service with CO/NY, it only required the PIN once and that was if the phone was turned off for more than 20 minutes.

But then we also have our own voice mail system, and a PBX, which all cost money to run. A single measured business line is $15.00 a month. So with all the charges added up, it would probably cost about the same. Prices of phone service went up as of Jan 1, but the cost of toll calls went down. Supposedly, the two should balance out. But being that most of the calls are within our district and are not toll, I would say that that isn't true. We have a marketing agreement with Pac Bell, so there is some negotiation and fixing of prices. The PBX system, and the phone instruments are under a service contract. The user has to pay about $300 to purchase a phone. There are also the wages for me and my cohorts in our department that work on the phone and data network, which have to be taken into account. BTW, the voice mail system is cheaper than Pac Bell's, but it doesn't have as many features as theirs, and I don't believe it is as user friendly, either.

I have often wondered if this over-charging, at least for State Universities, is a way of transferring charges from the University Administration to the University Departments. State Legislatures prefer that funds go to Departments rather than Administration. However the major user of telephone service, and many other services, is the Administration. For a variety of reasons, most of the University operator services are used by the administration. For example, the administration is the principal user of operator services because people calling departments and faculty usually know the direct-dial number while numerous inquiries go to the administration. By bundling charges and thus over-charging departments and under-charging administrative services, the administration can, in effect, transfer money intended for education to administrative services. Perhaps this over-charging occurs at private Universities for similar reasons? David G.

From: "Lee D. Rothstein" Subject: Enhanced Telecommunications Services for New Hampshire Organization: MV Communications, Inc. Date: Tue, 7 Feb 1995 19:25:32 GMT [Disclaimer ********** The text below was intended to be a press release. It was written by Lee Rothstein, of VeriTech, with the help of Tim Platt, of Orr and Reno. The views expressed in the release can only be ascribed to Lee Rothstein. Because there was not time to poll the members to determine the extent of agreement, on both the bill and the press release, the release has not been issued, as yet, by the Consortium. The bill, however, goes before Senate Committee, Thursday. If you are a Member of the Consortium or attend the meetings, please contact Lee Rothstein with your views. Whether or not you attend NHTC meetings, please contact your New Hampshire State Senator to indicate your support for law and other efforts that foster Internet availability, accessibility and bandwidth in New Hampshire.] ====================================================== Enhanced Telecommunications Services for New Hampshire ====================================================== February 7, 1995, Concord, NH. The New Hampshire Telecommunications Consortium (NHTC) is committed to bringing advanced telecommunications infrastructure and enhanced services to the State of New Hampshire. The time is right for this effort. Many people speak of the "super-information highway" vision. Even more people, companies and institutions participate in, and contribute to the ballistic growth of the Global Internet. Consequently, the NHTC believes that proactive steps must be taken by government, business and the community to ensure that New Hampshire has sufficient, powerful and economical access to enhanced telecommunications services at the earliest possible opportunity. Such efforts will ensure the well-being of the State in economic, education, health, safety, and social areas. Special efforts are required because, on the one hand, New Hampshire must compete in the global economy, but on the other hand, we are a sparsely populated and small state that wishes to maintain our high quality of life and environment. To this end, some of the telecommunications consumer members of NHTC have proposed a bill that would change the telecommunications regulatory climate in New Hampshire so that citizens and institutions of the State can benefit from these enhanced services. The draft of the bill was composed by Tim Platt of Orr & Reno, at the request of the NH BIA. We are very grateful to Tim for his efforts on behalf of the Consortium. Specifically, the bill is aimed at increasing competition for delivery of these enhanced services. This, in turn, will allow the State, it's institutions and citizens to remain competitive with other forward-looking states and regions that are well-along this process of fostering advanced telecommunications infrastructure and enhanced services. The proposed bill (NH Senate Bill 22) has been sponsored by State Senator Beverly T. Rodeschin of Newport (Senate District 8). Ms. Rodeschin is a member of the Economic Development Committee. Senator Rodeschin's home phone number is 863-1941. The Chair of the Committee is Carl R. Johnson of Meredith (Senate District 3). His legislature phone number is 279-3177. His home phone number is 279-6492. If you would like to call the senator of your home district, please call the New Hampshire Business and Industry Association at 1-800-540-5388 for further information. Senate Bill 22 maintains traditional distinctions between telephone companies and telecommunications suppliers (the former being a subset of the latter), and between basic and enhanced services. Basic services include most services that we commonly think of as involving the telephone for dial-up voice, fax and data (modem) communications. Enhanced services include data, video and imaging services, especially when they make use of high speed digital infrastructure. The bill is specifically directed at improving advanced telecommunications infrastructure and the pricing, availability, and competitiveness of enhanced telecommunications services. The bill, as drafted, promotes telecommunications infrastructure investment in three different ways: The first option would allow telecommunications service providers (inclusive of telephone companies) to make investments in technologically advanced infrastructures without regulation as to price of the service based on these infrastructures. This would allow access and usage of enhanced services at substantial discounts to current telephone rates. The second feature of the bill encourages telecommunications service providers to work with businesses, institutions and the community to develop pilot projects that satisfy the needs of institutions and individuals. Infrastructure developed as part of a pilot project should also be offered at a discount, and, if made by a telephone company, may be included as part of the rate base infrastructure, if a telephone company makes such request. The third option would allow telephone companies to treat such investments as part of their existing networks, if they elected to do so. Pricing under this third option would be based on traditional tariff filings. The NHTC believes that efforts such as the proposed Senate Bill 22 will be absolutely essential to the well being of New Hampshire, her institutions and citizens. Senate Bill 22 comes up for committee hearing on February 9, 1995 before the Senate Executive Departments and Administration Committee. The NHTC encourages all interested parties to contact their senators and representatives expressing their support for the bill. While Senate Bill 22 may not be a perfect vehicle for bringing New Hampshire into the age of the Global Internet and the Information Superhighway, it can be an effective first step in bringing enhanced telecommunications services to New Hampshire, quickly. Both comments and amendments that will get New Hampshire on the right path, quickly, are invited. The New Hampshire Telecommunications Consortium is composed of business and community organizations dedicated to bringing the super information highway, in all of its forms, to New Hampshire. Members include large telecommunications users, providers and other business groups.

The reputation of Finland as a country that holds freedom of expression, justice and human rights in high esteem has suffered among the world-wide Internet community. So far Finland has gotten a lot of positive publicity as the home of the best-known anonymous server, anon.penet.fi. These servers enable safe net discussion of sensitive issues, such as reporting violations of human rights. The ease with which the Church Of Scientology (with the help of Finnish police) obtained sensitive information has caused great concern and uproar. With the help of the finnish police, the Church Of Scientology found out the identity of a person who had published material on the Church of Scientology anonymously on the Usenet newsgroups. At the same time there has been a lot of speculation on the net on whether the recent child porn scandal (which was totally unsupported by hard evidence) might be connected to the Scientologists' interest in the anonymous server. ___________________________________ Anonymous servers enable anonymous discussions via electronic mail and newsgroups on the Internet, used by millions of people all over the world, and are vital for support of freedom of expression. These servers are used by people who are under pressure or persecuted, people who report offenses of human rights or even discuss their personal problems and sufferings. One of the longest-lasting and probably the most famous anonymous server is anon.penet.fi, created by the Finnish Internet specialist Johan "Julf" Helsingius back in 1992. Every day more than 7000 messages are automatically handled by the service, and there are over 200 000 registered users. The popularity of the server is largely due to its trustworthiness, based on both the personal reputation of Helsingius among the network community, as well as on the good reputation of Finland as a country where individual rights, privacy and freedom of expression are respected. This kind of reputation is important, since there are lots of people and organisations in the world that would rather see the anon servers being shut down. Governments that violate human rights, as well as other organizations banning public and open discussion of their activities, such as the Church of Scientology, are among these. The Church of Scientology has in fact approached the people offering anonymity services, threatening with lawsuits unless the anonymous discussion in scientology-related newsgroups stops. In fear of lawsuits many American servers have either stopped altogether or strongly limited their activities. The flow of events: On Thursday, February 2, an American representative of the Church of Scientology (CoS) contacted Johan Helsingius, informing him that some information residing on a private and closed CoS system had been made public via the anon.penet.fi server. Based on this they have reported a burglary to the Los Angeles Police and FBI. The representative of CoS asked Helsingius for the real identity of the individual that had posted the confidential information. After Helsingius had made it clear that he was in no position to give out the information, he was told an official request to the Finnish Police was on its way via Interpol. The next day, February 3, the Finnish police contacted Helsingius, informing him that if need be, they would get a warrant of search and seizure. The necessary documents for these actions were promised for Monday. On Monday, February 6, the Swedish newspaper Dagens Nyheter published an article based on the investigation of Mats Wiklund from University of Stockholm. The article stated that child porn was distributed to Internet from the Finnish anon.penet.fi server. The Finnish media picked up the story, with headlines such as "Internet distributes child porn from an address in Helsinki" (Helsingin Sanomat) and "Internet flooded with child porn" (Ilta-Sanomat). The first public reaction in Finland was based purely on the initial article in Dagens Nyheter. Meantime, the Internet community started to investigate the matter. The child porn statements caused amazement, as the anon server has (due to heavy traffic) been forced to limit the maximum size of messages, and ban postings to groups containing pictures altogether. At closer look the Wiklund "research" is revealed to have been made sloppily and without enough expertise. The information needed to reveal the sender of the articles has not been saved, and the famous pictures themselves are nowhere to be obtained for a closer look. The only picture that is actually included in Wiklund's report seems to be taken on a nudist camp. Wiklund has investigated four newsgroups dealing with sexual pictures, checked 5651 postings and found 8 pictures of adolescent nude children, none of which are (according to Wiklund's own report) actually pornographic. After a closer look at the pictures in those groups, they are shown to actually come from United Kingdom, not Finland. Wiklund admits that he never thought of the possibility of the source of the pictures being forged. On Saturday, February 11, Johan Helsingius reveals the true nature of events and the headlines in Finnish media quiet down. On the Internet there follows a lot of lively discussion and questioning of the motives of the Swedish researcher, the person who forged the source of the pictures, and the journalist of Dagens Nyheter. Some writers suggest a connection to the attempts by the CoS to silence anon servers. Since the authorities don't seem to be investigating the case, Helsingius himself files a request for investigation with the Finnish police. The initial investigation reveals no crime committed at least in Finland. In the meantime, on February 8, the Finnish police serve Helsingius with a warrant for search and seizure, and obtains from Helsingius the electronic mail address of the anonymous user that the CoS wants. Within an hour after the Finnish Police gets hold of the information, the Finnish representative of the CoS informs Helsingius legal representative that they received the information. On 14 February the criminal investigation on the scientologists case is dropped. Helsingius gets this information on February 17, and reveals the situation on some discussion groups and mailing lists on the Internet. This announcement has caused a flood of electronic mail, and a huge outroar among the Internet community. During the weekend, Helsingius received hundreds of comments and queries, most of them questioning the actions of the Finnish authorities. February 19 the maintainer of an anonymous service in Amsterdam tells Helsingius that the Church of Scientology has approached him again, threatening with legal action unless the anonymous participation into the discussion on scientology is stopped. This time the issue would be claims about illicit distribution of copies of copyrighted computer programs. ----------------------- [TELECOM Digest Editor's Note: Those Scientology people are very strange. So was L. Ron Hubbard, their founder for that matter. Originally an author of mostly science fiction books, in 1949 Hubbard went to a convention of science fiction writers and made the comment that real money in the world was not to be made writing books. "If you really want to make lots of money start a church ..." he said. Well, we know that much is true, I've thought a couple times about starting one myself. Hubbard then wrote a book called "Dianetics: The Modern Science of Mental Health" which seems to have sold quite well (he has been dead for a few years but the book is still in print) and from that publication came the Church of Scientology. They have always been very agressive about getting their way and they don't hesitate to sue or otherwise harass anyone who writes an expose of their activities. With Auditors and Engrams and their infamous E-Meter (a device which measures Engrams!) they'll clear you of whatever is wrong in your thinking processes. Several years ago I read a few things about their tactics toward their perceived enemies. I'm not surprised they are now turning their attention to Internet. The comments by Helsingius sort of confirm what I said here the other day where remailers are concerned: they do have records of who says what, and will keep them for use as necessary. He went the full measure and required the authorities to produce a warrant before turning over the information they sought, and that is admirable. But when I was doing the same thing with postal mail years ago, the other fellows I knew in the same business used to take a somewhat more practical view. The attitude was (regards postal inspectors, police, etc) we have to live with those guys all the time. If you know that in fact to get a warrant all they have to do is go ask a judge for one and they'll be back in a few minutes or a day or so later, then give them what they want and save time for everyone. Some will even call on the phone to request a warrant and have it delivered five minutes later over your fax machine! Then they look at you with some disdain as if to say "old pros like you and I need not waste a lot of time on preliminaries, or the opening exercises." I hope Helsingius afterward at least notified his user that there had been inquiries made. That's a courteous thing to do.

We want to offer a LAN interconnection service supported by this upgraded CATV network. Our idea is to install a Token Bus like network on parts of the CATV net, with point-to-point links between Token Bus islands. Three questions about this project: 1. Do you know the existence of a LAN interconnection service based on the CATV cable? 2. Do you know equipment that can be used for such a service? 3. Token Bus (IEEE 802.4) equipments can not be used directly, because the IEEE 802.4 normalized frequencies are not free. Can I nevertheless use these equipments with just an external remodulator to make the signal fit in free bandwiths on the TV cable?

There are around five cellular phone service providers in our country, and most of them use E(TACS). One uses GSM, and says that this is the latest technology in cellular telephony. They say that it would make international roaming possible (although they say that it isn't possible right now). Also, this service provider that uses GSM says that they're the only provider that's 100% digital. One of the implications of this, they claim, is that their phones can't be cloned as easily as the analog ones. Is this true? Also, they say that analog systems are very prone to charge errors. Is this also true? Or are they just trying to scare me from going to the other service providers? Thank you very much.

Matt, I can't offer any specific advice, but I can give you some information that might be helpful. Assuming that by using the term "Pair Gain" you mean that Pac Bell has you on an AML line, you're probably on an analog "added main line". My tech guys tell me that the most you will probably get is 2400 baud. If you're on a digital AML, then you should be able to go above 9600 baud with no problem. The company that I work for, PairGain Technologies, sells a digital AML called PG-2 that can support dialup modems at speeds up to 19.2 kbits/s with no problem. (It may be able to support higher rates, but 19.2 kbits/s is what they last tested a PG-2 unit at). However, my tech guys also tell me that Pac Bell doesn't buy any PG-2 units from us. Instead, they buy units from Rockwell, Wescom, and Adtrans. I don't know if these are digital or analog AML's, but it seems the trend is to not buy anymore analog AML's. Maybe you can ask your phone company to move you over to a digital AML (perhaps, from PairGain Technologies ;) from an analog AML.

Martin McCormick WB5AGZ Stillwater, OK OSU Center for Computing and Information Services Data Communications Group [TELECOM Digest Editor's Note: Imagine two motorists driving in opposite directions down a narrow one-lane road with no room to pass each other. They meet in the middle somewhere, and each one leans out the window and glares at the other, wanting *them* to the be one to back up and get out of the way. 'Glare' in the conventional sense means to look in a hostile fashion at another person. Two calls on one pair each going in the opposite direction are certainly hostile and/or incompatible with each other. A state law on the books in Kansas at the end of the 19th century detailed exactly how to handle the problem of glare, where railroad trains were concerned: "If two trains both on the same track approach each other from opposite directions, then each shall come to a complete halt and wait until the other train has passed entirely." Yes, that was a law in Kansas over a hundred years ago, repealed quite a few years ago when the Kansas legislature did a major overhaul and re-codification of the statutes of that state. In the case of telephonic glare, there is really no other option except for both parties to disconnect and start all over again unless the party on the inside line of the PBX is willing to be nice about it and try to transfer the call off his line and back to the attendant somehow, even though she did not give the call to him in the first place.

Paul Garfield (garfield@vanilla.cs.umn.edu) writes: > Long ago I remember terms like loop start and ground start as > different protocols for handling signaling bits on a T1 line ... Paul, it couldn't have been reeeealy long ago or you'd know that loop, ground, wink, etc. originated on analog lines (local loops from the dial tone switch, etc.) and trunks (facilities between switches). See ..... sometimes it pays to be old. The best way to look at your question is to begin by understanding that T type carrier is simply the transporter of signaling information. It doesn't do anything but extend the native signaling/supervision form of the equipment to which it is connected, which is (in voice applications) usually a switch, but sometimes private line equipment. The T (or any other type of carrier) is at its core nothing more than a distance extension methodology to allow devices such as telephones to be located beyond metallic circuit distances. The circuit signaling type is unrelated to the carrier system (other than its ability to transparently transport the supervision states). So, the first part of answering your question is to divorce the carrier from the signaling. The next part is just basic phone stuff relating to signaling and/or supervision. Loop start is the type of supervision generated by your local POTS (plain ol' telephone service) telephone set. The local serving dial tone switch applies (normally in the USA) -48v battery to one (usually the ring) of the wires in the pair coming to your phone. It applies switch ground to the other. When you go off hook, your telephone set connects the tip and ring wires together thus forming a "loop" from the switches' point of view. This loop starts the call process. Ground start adds one new wrinkle. In the idle state the switch still applies -48 battery on the (usually) ring wire but leaves the tip open. When you want to make a call your device (PBX or special phone) must first apply a local ground to the (usually) ring wire. This will cause current flow on that wire which the switch will interpret as a request for ground on the (usually) tip wire. From here on out the process works like loop start. We've always called this operation RING GROUND START because you have to ground the ring wire to start the dialing process. This process also helps prevent glare, but I'll leave that explanation for another posting. The other types of supervision you asked about are usually not line oriented. They are used on trunks. Wink just means a momentary off/on hook change which alerts equipment to follow on with some action. MF outpulsing is a good example of what happens after one switch sees a wink on a trunk from a distant switch. The word wink comes from an old type of signaling test box which had two lights that lit up when the line and drop were on hook. The lights would go out on off hook conditions. A momentary change from on to off and back to on would cause the light bulbs to blink or wink at you. Hope this helps - we have a two day on-site only seminar which covers these basic processes, if youre interested in more details.

The relevance to T1 is only that the AB signalling bits control the signalling functions performed in the particular channel units that provide the analog interfaces. The base definitions for the interfaces are analog. To summarize: Loop start is the regular POTS line where closing the loop signals off- hook to the Office and power ringing signals an incoming call. Disconnect from the office following an answered call is typically indicated by removal of battery (which dropped the hold relay on the once pervasive 1A2 key system. The major difficulty with loop start is that an incoming call can be connecting during the silent interval of the power ringing and it is possible to close the loop for an outgoing call during this interval. The incoming call will then be answered. This can be reduced by immediate ringing (connecting the line to an active cycle of power ringing immediately upon seizure) but this is typically not available. Ground start originates calls to the Office by grounding tip. Calls from the Office are indicated by tip ground (and power ringing). Ground start also provides positive disconnect indication from office under all conditions. Ground start is the typical analog PBX trunk interface. Wink Start is not a trunk type but a signalling protocol that can be used on Reverse Battery (DID) or E&M trunks. The wink indicates readiness to receive digits. The wink is a momentary offhook after which the originating end transfers digits by either pulse dialing or inband tones. Off-hook is returned when the addressed station answers. Reverse battery uses battery from the CPE with normal polarity indicating on-hook and reverse polarity indicating off-hook. Reverse battery is one way in to the CPE. The channel units are called DPO and DPT (Dial Pulse Originating and Terminating). Earth recall is the U.K. version of ground start. Perhaps someone on the other side of the pond can elaborate on this and other European Interfaces. Wally Ritchie Ft.

Most of your regular phone lines are loop start; you pick up the phone and there is a loop or circle from the phone thru the equipment and back to you. Ground starts lines that require a ground on one side to give dial tone, and they may be business lines or lines other than the regular residential lines (they can be ground start but not usually). Loop and ground start are not just analog. Wink start is on a trunk or connection that requires the other end to send a wink. The wink is like saying it's okay to send digits to connect your call. [TELECOM Digest Editor's Note: Don't you think however that ground start lines are a lot more secure in applications like modem dial in lines or situations where the power could go off and concievably leave an inbound caller connected to your system with the ability to use one of your outgoing lines?

Well, UpFront @ 1-800-888-3510 is a pretty good deal for a prepaid card. I know NOTHING about the company, if it's an MLM. I just called the company and they sent me a card. You can recharge it with check or credit card. Rates are $.20/min day, $.16/min eve, and $.13/min nite, anywhere in the US, including IN YOUR OWN STATE. This last point is better than a lot of calling cards. There is a $.10 surcharge per call though. I plug this company because I like the rates; I have nothing else to gain. If someone knows something more about UpFront, please post. I'm curious. Shawn Gordhamer shawnlg@netcom.com [TELECOM Digest Editor's Note: It sounds like a decent deal.

It sounds like a typical phone company, warning people that their lives may change as a result of work they are doing. A DMS-100 is a Northern Telecom "switch" that is installed in the CO. It's the actual switch, controlling all network in that particular area (as they say, "within that switch"). Sounds like they have to add another switch because they need more capacity that what they have installed presently. Other than your prefix changing (prefixes generally can't be shared across switches ... Centrex is an exception), I wouldn't expect much else to change. Bottom line is that plain old telephone service (POTS) is POTS. It won't affect your modem dialing, etc. God only knows why they would even send out such a notice, because other than your prefix probably changing, you probably won't notice anything different at all. gregicg@cadvision.com Greg Habstritt Intellitech Communications Inc.

When a Nova Scotia native and I were looking at a map of Minnesota together, he pointed out that the Northwest Angle was cut across completely by Lake of the Woods, leaving part of it attached to Manitoba but separated from the rest of Minnesota. He said, "Look. There's a part of the United States where you have to go through Canada to get to the rest of the U.S., unless you fly or take a boat." I answered, "Yes. It's called Alaska." Point Roberts is not unique. I don't know whether telephones in the detached portion of Minnesota (occupied mostly by Northwest Angle State Forest and the Red Lake Reservation) are in area code 218 or 204. David W. Tamkin Box 3284 Skokie, Illinois 60076-6284 dattier@wwa.com MCI Mail: 426-1818 +1 312 714 5610 [TELECOM Digest Editor's Note: According to my Rand McNally state map of Minnesota, Northwest Angle *Provincial* Forest is located entirely within Manitoba. The small section of the Red Lake Indian Reservation (separated from the rest of the reservation, which occupies a huge chunk of northern Minnesota according to the map) is entirely in the USA. A small community up there is called Angle Inlet. The boundary seems to come down through the water in such a way that neighboring Bigsby Island, Big Island and Falcon Island are all in Ontario, Canada. A couple of small unnamed islands sit very close off the southern tip of Falcon Island, between it and Red Lake Indian Reservation which are barely inside the USA. Even though it appears to be in the USA, the only road shown on the map which leads from the provincial forest up to Angle Inlet is referred to as provincial highway 525, even within the USA part. Now if you look at a map of Manitoba or a map of western Ontario on those the boundary line is drawn so that a small portion of Falcon Island and Big Island are also part of the USA -- just the western and southernmost tips of each. I am amazed that David, who once took an entire evening driving me all over the northern boundary line between 312/708, carefully pointing out house by house, street by street and backyard by backyard where 312 ended and 708 began, as well as where Centel's territory started and Illinois Bell's ended does not know whether the phones at the Indian Reservation -- if there are any -- are serviced out of 218 or 204. Actually, I think they are serviced out of 807, and the central office in Kenora, Ontario which is the nearest town of any size. And what area code covers the largest geographical area? Probably 403 which is all of Alberta and the Yukon/Northwest Territories, although 907 in Alaska is also large. 808 has now become huge also since where it traditionally was only Hawaii in the past, now it also includes Midway Island, some distance away and the islands in the US Pacific Trust. Also, watch and see if 'country code 671' in Guam doesn't soon become 'area code 671' in the USA dialing plan. It is the one remaining place in the scattered possessions of the USA which still has to be dialed as an international point -- and although you young'uns wouldn't remember it, we used to have to call Hawaii through the operator as an international call also, *even after it became a state in the USA* for a few years until 808 was assigned.

Is it this one? Hahn and Stout's original "Internet Yellow Pages" (cf. BKYELPAG.RVW)? NIS (Network Information Services, the "yp" programs)? I suppose it doesn't matter: we'll see all manner of "yellow pages" over time. This outfit, the McKinley Group, is certainly serious about the task. All entries have a standard format with title, rating (zero to four STARs -- yes, they made an acronym of it), brief description, keywords, audience, and user information, ending with a URL (Universal Resource Locator) listing. Once you get used to it, this is a very quick overview containing almost everything you need. For old hands at the Internet, this is a very handy resource. For newcomers, it might be a bit terse. There are seven "chapters" of introductory material. These total a lot less than thirty pages, and are very hard to follow, as they are interspersed with directory entries. The differences between mailing list programs are downplayed and the explanation of URLs fails at several points. (By the way, don't expect any consistency in the use of forward and back slashes in URLs here.) (In fact, don't expect all the URLs to *be* URLs.) The listings have a very heavy emphasis on mailing lists and newsgroups. ftp sites are far less common in the directory than on the net. There are a great many listings for commercial services whose only Internet connection is that you can use telnet if you have an account. (If those systems are time sensitive, telnet might not be what you want to use for access.) There are paid advertisements, in the same format as other listings. You can't have everything in an Internet directory: the net is too big and changes too fast. Having done a few dozen searches, I found that the total number of listings, and the index access, to be less useful than the Hahn/Stout work. Offsetting this, to a certain extent, is the fact that the "keywords" in each entry act as a second level of indexing. Following a keyword search is something like reading a Thompson Chain Reference Bible, but it does guide your search in directions you might not otherwise have chosen. (Ahem. Most computer viruses are *not* obtained from downloaded files. Yes, you *can* have a virus attached to a Windows document. VIRUS-L is also comp.virus. And why does the "Computer Viruses" keyword have CAD sites in it?) The standard format and keyword linking are good features and promise well for future editions.

However, last night while driving back to the city from New Haven, in SNET Cellular territory, I passed an accident on I-95 which had just happened not ten seconds before, on the northbound side, near exit 17. Seeing nobody on the scene I called it in to 911. Dial 911, hit send, busy signal. Okay, *911, send ... it wants my PIN! This is a major safety problem. (Eventually I get through and the state police says thanks, we have troopers on the way.) I objected to being required to have a pin from the start but they will under no circumstances that I have found remove it. They did send out a flyer saying that they will not charge airtime for the time to dial the PIN, but who knows how accurate that will be.

My name is D.J. Martin. I work for Sprint/United Telephone-Florida and am new to Internet and TELECOM Digest. I have a question that I cannot answer and have been to several sources seeking advice to no avail. If you have the time, I would like your thoughts on it. Scenario: A person pushes the play button of their answering machine and has a message "the number you have dialed cannot be completed as dialed. You must use a zero or one." This is an outgoing call message. Or they have a message of a operator asking if they can help them. Operators do not call people to assist them. Although both cases appear as an incoming message, no call was made from the location. This problem has been reported to me from all types of central offices and answering machines. I have called my home from my cellular phone, reached my answering machine and left a message. Twenty minutes later my cellular phone rang and it was my answering machine with my outgoing message. I would appreciate any ideas you have on this subject. My address is MARTINDJ@UTELFLA.COM Thanks for your time. D.J. TELECOM Digest Editor's Note: Welcome to the Internet and this Digest. You might want to correct your login name and the way your messages go out to the net since they refer to you as Philip D. Martin. We've touched on this topic from time to time, and one of the most common reasons for the scenario you describe is that pranksters with three- way (or more) calling like to hook together strangers at random just to listen in amusement as the two (or more) called parties each angrily accuse the other(s) of making the calls. After all, they know *they* did not make it. They dial your answering machine, let it start its outgoing message, then quickly flash the hook, get new dial tone and dial some(one)thing else, click again, and by that time your machine is ready to start taking a message from the befuddled operator who came on the line asking if she might help, or the intercept message which announces 'your call cannot be completed as dialed'. Occassionally they dial into a conference bridge then put the bridge on hold and dial some other person so that that person (or his answering machine) get to hear several people talking at once on a call in the background they know they did not originate. The person wakes up in the middle of the night to a ringing phone, answers and hears these two other people having hot chat or whatever. Naturally his first reaction is he went into the Twilight Zone or something. Or he comes home, listens to his answering machine and hears two other people talking in a conversation of their own on his tape; they are oblivious to the whole thing. Or maybe he takes your outgoing message and plays it into the incoming message on someone else's machine. Maybe instead he takes your outgoing message and plays it to a live but unwitting listener on the other end. Everyone becomes convinced the phone system must have some major malfunction going on. I said (or more) above because some people have two line phones with three way calling on each line; they bring up a three-way call on each line then use their own conference button to connect all four of the innocent parties. Naturally at least one or two of the recipients of the calls will be ignorant (I mean ignorant!) and that adds to the 'fun' of it all ... As to your own answering machine taking a message then 'calling your cell phone twenty minutes later to play your outgoing message' my assumption is that its not supposed to work that way; i.e. your answering machine is not a real fancy one that makes outcalls. Therefore it might behoove you to stop and think for a few minutes and try to identify a person in your life who has all these traits in common: (a) they know your home phone number; (b) they know your cellular number; (c) they have three- way calling; and (d) they like to play pranks with the telephone. I am also assuming in the middle of this no one spoke up and said 'oh sorry, hold on, the answering machine started" or anything like that. In other words it was not a 'legitimate' call from someone at your home who accidentally bumped the play button on the machine while they were dialing your cell phone or whatever. I got one of those calls once. I looked at my Caller-ID box in the middle of being harangued for waking someone up at 2 in the morning ... I asked them, is your number xxx-xxxx? No, they said it was not. I hung up and then dialed the number on the display. I had to let it ring a good thirty or forty times but was prepared to just leave my phone off hook the rest of the night and let it ring all night if that was needed. Presently someone answers; a real innocent, questioning 'hello?' ... Too innocent and too questioning; too naive ... he sounded to me like a young phreak in about the 7th grade or so. "We like to play games with our phone at night do we?" ... "What do you mean?" ... "Tomorrow I am going to look up the address which goes with this phone number then call your parents and talk to them ..." "Oh, don't do that ..." Well, that was the clue right there. There can be other reasons for the scenario you describe but they are rare, and outrageously boring to sit here and describe. Try and eliminate phreaking by (chronological or mental) children before investigating further.

Yesterday, around dinner time (ain't it always that way), I got an interesting call. It was a market research call (you know, let's play 100 questions). This one was (clearly) Bell Atlantic trying to figure out how to get into the long distance market (surprise, surprise!). The questions focused on two main areas: (1) Trying to expand their 10NJB business I live in Hoboken, NJ, which is right across the Hudson from New York City. Because of an exception in the MFJ, Bell Atlantic is currently allowed to provide LD service into NYC, which you access by the carrier code 10NJB. They wanted to know if I knew of it, how I heard of it, etc. Then they asked if I'd consider making them my default carrier. (No) They then went through various proposals for pricing and packaging plans for calling into NYC. None were particularly good (I had a hard time stiffling a laugh when he suggested a $.15/minute rate all the time). Other plans were a fixed fee for a fixed number of hours. Somehow, a fixed fee for unlimited hours wasn't on the list. The only thing unusual was interest in whether I have a home computer and how much "work at home" I do. I guess those ISDN trials will be underway soonest. (2) Testing the waters for full LD service They asked me some questions that were clearly oriented towards scoping out the full interlata LD market. Nothing exceptional here. What would make me switch (price). How much of a percentage discount would it take to make you switch (percentage of what, I asked -- no answer). I can only hope that their offering is better put together than their survey ;-) Charles McGuinness [TELECOM Digest Editor's Note: Ameritech now has a survey company they use to call everyone who called Repair Service within the previous week. They start out by asking questions about your opinion of Repair Service (how fast were you answered, how quickly were repairs done, etc) but soon enough they get into questions about Ameritech as a long distance carrier, and how would you like that? The repair questions are positively phony; its the LD stuff they want to talk about, but its like they are trying to be cool and very casual about it. Their final question was, 'are you aware that Ameritech and AT&T are two separate companies?'. I thought for a minute trying to thing of a good answer to that and finally I said, "No! Really? When did that happen?".

After my original posting I received about 14 responses, most of which had similar horror stories to tell about MCI billing problems. As I mentioned previously, the bill was paid in full by credit card in January. This week (of 2/5), we had a phone call from MCI where we were told we had not paid our bill -- I interrupted and told the woman, "Yes, we had, by credit card." "We already have the credit card billing with the MCI payment on it" -- the exact amount she was saying we still owed! She hesitated a moment, and then said, oh yes, I see it now! Makes one wonder just how complicated a form she is looking at, and what is wrong with their programmers if such a field is not checked before the bill is flagged as not paid! In addition, on Feb. 9, we received notice in the mail warning us that our bill would go to a collection agency if we did not pay. [This is the second mail from MCI in the past week -- we did receive a listing of calls made, though it did not appear to be a bill -- my guess is that this resulted from an emailing to an MCI employee whose address I pulled off of a news group, and who faxed the original posting to MCI's Consumer Executive Customer Relations (Residential).] In any case, my wife called this time. She got ahold of a woman and explained the situation to her. But no, the woman said, her records did not show we had paid. She, in turn, called another office, who then told her, yes, we had paid! The woman assured my wife that the problem would be cleared up. We are not holding our breath. The MCI nightmare continueth.

Like all exams it was multiple choice. There was one answer about bleeders and interlock switches on the access door which was the answer they were looking for at the time, a couple of answers which were close, and one all-time great answer: "Buy double indemnity life insurance." At least there was a time when SOMEBODY in the government had a sense of humor. P.S.: I refuse to say exactly how long ago this was. But in case anyone thinks I'm really old, when I got my first Radio Telephone license I went around looking for a summer job in various TV repair shops and met one owner who had his first Radio Telephone license on the wall.

That Act regulates telemarketing calls to residences. It requires each telemarketer to maintain a "do not call" lists and to put you on its list if you so request. Unfortunately (and rather amazingly), a telemarketer is still allowed to call you once a year without penalty _after_ you have asked to be put on its "do not call" list; however, the second call in any 12-month period entitles you to sue for $500 or actual monetary damages, whichever is greater. The FCC's document is headed PUBLIC NOTICE; it was released January 11, 1993 (yess, 1993) and there's a reference number DA 92-1715. The title is Consumer Alert: Telephone Solicitations, Autodialed and Artificial or Prerecorded Voice Message Telephone Calls, and the Use of Facsimile Machines. It's eight letter-sized pages long.

The original idea was to keep the two networks totally separate in order to guarantee good interactive response on the second WAN. Problem: For system administration, operating, control, and maintenance purposes, we do need connectivity between the two networks. Our CISCO gurus tell us that the only way to have connectivity and still keep unwanted traffic off the 2nd WAN would be to use only static routing - which would create an administrative nightmare because then apparently every router has to know every single IP address. Question: Can we use a real gateway (i.e. more $$ than a regular CISCO Router) to have connectivity between the two networks, but still ensure that only packets which have their source or destination on the second WAN get routed onto this second WAN? In other words, would a gateway be smart enough to make its routing decisions strictly on the basis of the FIRST byte of the source and destination IP addresses, without knowing all the IP addresses on both networks, i.e. without the administrative table-maintenance nightmare which static routing via CISCO Routers seems to require. Again, the goal is to keep the second WAN free of all traffic which can be routed over the standard (first) WAN. Our worst nightmare is a large file transfer or some Netware IPX/SPX transfer jeopardizing the interactive TCP/IP responsiveness on the second WAN. Which type of gateways should we be looking at? Any recommendations? Any help would be very much appreciated. Please reply to TELECOM Digest or via email to "karl.finkemeyer@fmr.com".

The Federal Communications Commission has ordered Pacific Bell and other ISDN providers to raise the number of required line charges for all ISDN products. For Pacific Bell customers, who have enjoyed among the lowest ISDN prices in the country, increases will range from a maximum of 29 percent for Home ISDN and Centrex ISDN, up to 43 per cent for SDS ISDN and as much as 50 percent for Primary Rate ISDN. Here's why: Until now, each ISDN line coming into your home or office was billed as one line. Now the FCC has ruled that each ISDN customer must be charged for each ISDN channel rather than each line. Pacific Bell has filed a waiver asking the FCC to restore the original one-for-one ISDN line charge. We believe ISDN must remain affordable and easy to access so that individuals, schools, libraries, researchers, and businesses of all sizes can benefit from the Internet. If you feel that the increased line charge will make ISDN less affordable for users like you, please E-mail your comments to us at fccisdn@policy.net, and we will carry your message to the FCC.

SONET/ATM-BASED BROADBAND NETWORKS: Systems, Architectures and Designs (March 29-31, 1995) It is widely accepted that future broadband networks will be based on the SONET (Synchronous Optical Network) standards and the ATM (Asynchronous transfer Mode) technique. This course is an in-depth examination of the fundamental concepts and the implementation issues for development of future high-speed networks. Topics include: Broadband ISDN Transfer Protocol, high speed computer/network interface (HiPPI), ATM switch architectures, ATM network congestion/flow control, VLSI designs in SONET/ATM networks. This course is intended for engineers who are currently active or anticipate future involvement in this field. Lecturer: H. Jonathan Chao, Ph.D., Associate Professor, Brooklyn Polytechnic University. Dr. Chao holds more than a dozen patents and has authored over 40 technical publications in the areas of ATM switches, high-speed computer communications, and congestion/flow control in ATM networks. NETWORKS FOR DIGITAL WIRELESS ACCESS: Cellular, Voice, Data, Packet, and Personal Communication Systems (March 6-8, 1995) This comprehensive course is focused on the principles, technologies, system architectures, standards, and market forces driving wireless access. At the core of this course are the cellular/microcellular/ frequency reuse concepts needed to enable adequate wireless access capacity for Personal Communication Services (PCS). Presented are both the physical-level issues associated with wireless access and the network-level issues arising from the inherent mobility of the subscriber. Standards are fully treated including GSM (TDMA), IS-54 (North American TDMA), IS-95 (CDMA), CT2, DCT 900/CT3, IEEE 802.11, DCS 1800, and Iridium.

Recently there was an ad drive by AT&T to get people to use their calling card for calls to the US and elsewhere. Of course, I signed up for one. Now as I understand it they are free as long as you don't use them. But for some reason I noticed sums of $8.50 being charged and then credited to my account. It seems that I have been put on some Military Saver scheme which is very strange since I'm not in the US military or anything approaching it. My question is: Is there an AT&T email address that I can send a complaint to and get my card sorted out? I have a feeling that it might be easier to sort out by email rather than letters or phone calls. Rob Scott Dept of Comp Sci, City University, London, UK. http://web.cs.city.ac.uk/homes/rbs/homepage.html [TELECOM Digest Editor's Note: I think the fact that they charged your account (erroneously) $8.50 then credited it (correctly) on the same or a subsequent statement demonstrates that the problem has in fact been resolved. Probably when they got your original application for service someone erroneously entered you in the military plan since AT&T does have such an arrangement for American soldiers in Europe. Later, or perhaps about the same time it was discovered this was incorrect and an adjustment was made. All the various AT&T international and domestic calling plans and calling card arrangements have numbers assigned to them. Someone at a terminal processed your application and enrolled you in (for example) 'plan #123' then they said, ooops, I meant plan #231 ... or similar. Or it went through and later a supervisor caught it. If you keep on getting marketing and promotional materials for the military plan *then* let us know, but I think you'll be okay. Honestly though, if it were me, I'd hope they did *not* discover the error. AT&T gives the soldiers a very good deal with absolutely rock-bottom pricing.

We at CLEAR in New Zealand are in the first stage of implementing NetExpert on a SUN Solaris platform ported to Oracle 7 and would like any contacts who are willing to swap information and experiences. For those of you who have never heard of this, this system is designed to receive messages from all manner of devices (switch, FOTS management systems, Routers, Lan analysers etc) and present the events to an operator. The system can also handle correlating events. In CLEAR's instance, we are looking at masking all subsequent alarms and only having the operator presented with the 'root cause' alarm. As you can appreciate, in the instance of losing a 2Gig fibre, this means a lot of chaff is separated from the wheat. In fact our last 565Meg fibre event resulted in over 2 Megabytes of data in a five minute period and to cull this down to one single event would save around 30 minutes of analysis. (My apologies if this sounds like advertising) Any responses to me personally, thanks.

GREENVILLE, S.C. (AP) _ MCI Communications Corp. has decided to add 475 workers to its residential sales center in Greenville. The move comes after the company hired 350 workers in November. MCI spokesman Matt Schwab said the success of the company's Friends and Family calling program prompted the expansion. He said the company has done most of the new hiring and will complete the task by the end of this month. ------------------------------ Date: Wed, 22 Feb 1995 10:30:13 EST From: Bob Keller Subject: Herbert Hoover (was Re: Humor at the FCC) In TELECOM Digest V15 #113, the TELECOM Digest Editor noted, in response to B. Z. Lederman : > Hoover was in charge of the Federal Radio Commission I believe > (forerunner of FCC). Mr. Lederman was correct that, prior to the FCC or the FRC, Hoover was Secretary of Commerce. I don't think Hoover served at the FRC. In fact, I am reasonably certain that he continued as Secretary of Commerce and was a moving force behind the legislative proposals leading to enactment of the Communications Act of 1934. The pre-1927 Commerce Department had jurisdiction over radio licensing. Hoover and his staff attempted to resolve growing interference problems from an uncooperative new broadcasting industry, by placing conditions on licenses restricting things such as frequency (or, in the parlance of the day, wavelength), hours of operation, etc. But the courts held, and the Attorney General concurred, that the Secretary's statutory authority did not go this far and that such restrictions were therefore unenforceable. It was in response to this problem that the Radio Act of 1927 was enacted, creating the Federal Radio Commission. The 1927 Act is remarkably similar to Title III of the current Communications Act. This is because the substantive regulatory portions of the Radio Act of 1927 was essentially transplanted into Title III of the Communications Act of 1934. The 1934 Act created the Federal Communications Commission and transferred to it the radio jurisdiction of the Radio Commission as well as jurisdiction over Telegraph and Telephone lines which previously resided with the Interstate Commerce Commission.

That was, I think, in 1929 when he gave an address to the nation over the radio on WLS. Hoover was the last in a series of three Republican presidents (Warren G. Harding, Calvin Coolidge and himself) who led the United States over a twelve year period 1920-32, each of whom got just a single four year term. After the disasterous chain of events in October, 1929 which led to the Great Depression in the 1930's in the USA, people soured on the Republicans, and when Hoover ran for re-election in 1932 against Franklin D. Roosevelt he was defeated, beginning a twenty-year period of Democratic leadership which would not end until 1952 when General Eisenhower, the war hero of WW-2 was elected. I think Hoover was appointed to his position at Commerce by Warren Gamiel Harding during his term, 1920-24. Radio (or rather, broadcast radio, on AM frequencies) as we know it began in 1921. During 1922-23 a half-dozen stations were operating in Chicago alone, including WLS and WGN, both of which are widely known and listened to today.

Hello, We are attempting to gather network reliability statistics on various IXC's, LEC's, and CAP's. Preferably this data will come from independant sources. We are interested in verification of error free seconds or outage frequency following installation. Information such as the percentage of error free seconds per 24 hour period for DS1 fiber with an interoffice route greater than 250 miles, would be helpful. And the same information for DS3 routes under 50 miles. The specific IXC's: MCI, AT&T and Allnet; LECS: US WEST, NYNEX, and PACBELL; CAP's: MFS and ICG.

Some of its postings also appear in alt.revenge, a group that appreciates somewhat more vitriol in its pranks. Some shens: -- When confronted by an answering machine, contributors were particularly creative. One fellow leaves messages in a normal voice, then suddenly switches to SUPERFASTSQUEAKYVOICE and then to v-e-r-y l-o-w, s-l-o-w v-o-i-c-e, leaving the machine owner with worries about his equipment. Another plays back the operator saying this number is not in service. And then there's the guy who recorded the AT&T intercept tape for callers to the Northridge, Calif. area. "Due to an earthquake in the area you are calling, your call cannot be completed at this time," and put it on his own machine; he lives in Chicago. (In that vein, Dayton Daily News cartoonist Mike Peters has been known to answer his phone with an empty coffee cup over his mouth, creating that perfect mechanical echo sound. Conversations go: "THIS IS MIKE. I CAN'T COME TO THE PHONE RIGHT NOW, BUT YOUR CALL IS IMPORTANT TO ME. PLEASE LEAVE A MESSAGE AFTER THE BEEP (*beep*)." "Mike, this is Charley, it's 2:15 Tuesday, and -- " "(Still in machine mode) OH HI, CHARLEY! HOW YA DOIN'?") -- Pagers are another foil. A contributor gets even with his weenie supervisor when he knows the super isn't near a phone. He calls the super's pager, then punches in the super's boss's number.

The interview is worth it -- the later part of the tape puts out fascinating ideas on the sociology of committees.)

The 8 Feb 95 edition of {Etobicoke Life} (a Metro Toronto community paper) reports of wayward phone connections that lost 10,000 callers. Those phoning the City of Etobicoke municipal offices were often left in "electronic ether" in the form of dropped or incomplete calls. Etobicoke's Commissioner of Administrative Services stated that the phone system was "overloaded", with calls from citizens regarding an interim tax billing blamed as the cause. While a $10,000 call queueing system installation is expected this summer, Etobicoke city staff is reportedly working with Bell Canada to avoid a repeat of that lost caller feeling. Fidonet : Dave Leibold 1:250/730 Internet: Dave.Leibold@superctl.tor250.org [TELECOM Digest Editor's Note: I am reminded of the tunnel flood here a few years ago when the Chicago River started backing up into basements all over downtown, including City Hall. In addition to the unusually high volume of calls to the city's public information phone lines from very concerned citizens wondering about the extent of the flooding (the source of the 'leak', a collapsed wall in one of the abandoned underground tunnels had not been located) and what they could/should do to save their possessions and themselves (for example, the Chicago Symphony Orchestra was in Europe at the time; staff members left in Chicago frantically went through basement storage areas retrieving instruments, musical manuscripts and other things, hauling it all upstairs to safe ground when they heard the flood was on its way to them; staff members at the Art Institute dropped everything and converged on their basement to begin rapidly hauling everything upstairs to safety; fortunatly neither institution was harmed in any way) -- in addition to the massive flood of calls to City Hall, overloading the phone system there -- the City Hall itself did have extensive damage in its second and third sub-basement where the old tunnel system connects in, putting all their telephone lines under water by mid-afternoon that day, along with completely submerging the Commonwealth Edison electrical sub-station located in the third sub- basement. Knowing for a certainty that City Hall would be 'offline' in a matter of an hour or two at the most (they could see the rising water in the tunnel branch near them) telco employees rushed to re-route the lines elsewhere. About 2 PM I was able to get through; the woman told me 'we will be staying until our lines go dead or until they evacuate us and make us leave' ... shortly after that calls to any 312-744 number (the city hall centrex) were greeted with dead silence. Just a click as my central office handed off the call, then nothing. Within 45 minutes however, they were ringing again, and the information ladies were on duty, having been evacuated to the Chicago Temple Building which is right across the street from City Hall. The Fire Department Central Alarm office which is also in City Hall had been offline for a few minutes also; telco got them re-established first then did the information lines followed by the general centrex operators. The information lines stayed open around the clock for the next several days (although the source of the 'leak' was discovered by mid-afternoon it would be several days before tons of dry cement-mix and other stuff dumped into the river above the opening would successfully seal the opening; it was on Sunday morning about 10 AM six days later that Mayor Daley came on our televisions along with engineers working for the city to announce that 'we have successfully plugged the leak, and underwater divers are down there now looking to make sure it is plugged') and they later reported handling about a hundred thousand flood related inquiry calls from all over the world over a five day period.

The package seeks to create a dynamic multimedia industry producing Australian content for Australian and international consumers, as well as providing a stimulus for increased access to cultural material by the community. The Multimedia Forums will be a major source of information about developments in multimedia and will facilitate the establishment of close and productive linkages between the cultural community and industry. These will enable Australia to better develop and commercialise interactive multimedia products and services. The Forums The forums will be accessible to a broad range of stakeholders, flexible in content and responsive to the needs of the sector. The Forums will consider critical technical and commercial issues such as best practice, intellectual property rights, finance, the requirements for market success, and the development of multimedia titles. Forums will be able to focus on topical issues which Government, the cultural community or industry believe need to be addressed, including for example, the Final Report of the Broadband Services Expert Group and the Innovation Statement. Forum One Forum One is a one day event which will be repeated in major capital cities (see Schedule) and will provide an update on the Creative Nation initiatives, including discussion on the implementation of these initiatives and information on when and how people can participate in programs and gain government support. There will be ample time for questions and answers. "An essential forum for anyone with an interest in multimedia as a business, a creative endeavour or for export" _Peter Cook - Michael Lee_ This forum will provide the opportunity to meld the interests and efforts of business, the cultural community, technologists, educators and the legal profession. Participants will be able to influence the future content, structure and orientation of the Forums Program.

Such languages have been used not only for applications such as the animation of logical specifications, the characterisation of database queries and knowledge representation, but also as high-level programming languages in their own right. In recent years, however, the requirement for greater expressive power has meant that languages based on first-order logic have been found wanting. In particular, since the concept of time is important in an increasingly wide range of applications, including the representation of time-dependent data and the specification and verification of concurrent and distributed systems, logics where temporal notions are central are beginning to be applied in these areas. Not surprisingly, executable forms of these temporal logics have been proposed in order to provide system developers with access to more appropriate logical techniques. Just as the development of sophisticated theorem-proving techniques for first-order logic led to executable forms, such as Prolog, so theorem-proving techniques for temporal logics are being used in the development of executable forms of these logics. However, each particular executable temporal logic combines not only a logical perspective, but also an operational model, drawn from its intended application areas. Thus a wide range of languages have appeared, exhibiting a variety of characteristics and execution mechanisms. Consequently, these languages have a wide range of application areas, including temporal databases, temporal planning, animation of temporal specifications, hardware simulation, and distributed AI. WORKSHOP AIMS The aim of this workshop is to provide a forum both for the exchange of ideas and for the identification of the potential roles and nature of the emerging paradigm of Executable Temporal Logics. Our aim is that the workshop will bring together workers in this area, to identify common ground, differing approaches, experiences, applications, open problems and possible future developments. In particular, we wish to encourage cross-fertilisation between different approaches. WORKSHOP FORMAT This workshop will build upon the success of the 1993 Workshop on Executable Modal and Temporal Logics that we organised as part of IJCAI-93, the proceedings of which are published by Springer-Verlag in the Lecture Notes in Artificial Intelligence series (vol. 897). The workshop will last for one day, and will consist of presented papers, group discussions and invited talks. We intend that the workshop will cover topics ranging from considerations of the state of the art, through to speculation on future developments. We will therefore solicit papers describing work in this area, including original ideas, new results, comparative studies and applications of Executable Temporal Logics. AREAS OF INTEREST Topics of interest include, but are not limited to, * theoretical issues in executable temporal logics * design of executable temporal logics * relationship between execution and temporal theorem-proving * operational models and implementation techniques * programming support and environments * comparative studies of languages * relationship of executable temporal logics to (temporal) databases * applications and case studies WORKSHOP PARTICIPATION To encourage informal interaction and the exchange of ideas, attendance will be limited to approximately 30 invited participants. Those wishing to attend are encouraged to submit either (a) an extended abstract (of no more than 5000 words) describing relevant preliminary or completed work to be presented at the workshop, or, (b) single page descriptions of research interests and current work, to be used to demonstrate the ability of the non-presenting participants to contribute to the discussions. Selected participants will be asked to provide complete papers to be distributed as preprints to the workshop participants. SUBMISSION DETAILS All submissions should include: author's name(s), affiliation, (complete) mailing address, phone and fax number, e-mail address and an abstract of not more than 300 words. Electronic submission is strongly encouraged (either as self-contained LaTeX, or postscript) and this, or five (5) copies of submitted papers should be sent, by March 1st 1995, to: Michael Fisher Department of Computing Manchester Metropolitan University Chester Street Manchester M1 5GD United Kingdom Email: M.Fisher@doc.mmu.ac.uk Telephone: (+44) 61-247-1488 Fax: (+44) 61-247-1483 Papers will be refereed and notification of acceptance will be given by April 1st.

What can happen then is that the DMS gives dialtone, then the 'please hang up and try your call again' recording comes on... of course the machine faithfully records this. That can be solved by having the DMS wait 30 seconds (in silence) before it gives the recording, but after it put the dialtone on the line and timed out. If you forget about a call put on call waiting, the switch will remind you that you forgot about it by calling you back, but that does not seem to apply to your 20 minute later notice. One other note, cordless phones when they get interference, if they don't have a security code on them, they can randomly pulse the line ... causing any sort of number to be dialed, or cause answering machines to think there is an incoming call ... that means the machine could record any number of things that are just happening to occur on the line at that time because of the cordless going on and offhook rapidly. On that same note, a little far fetched, if the cordless has your cell number programmed into it, and its stored in the base, not the handset, then it could be triggered to dial that number while this interference is occuring. Good luck! Jeff Regan Internet: JEREGAN@FLASH.LAKEHEADU.CA Ham Packet: VE3XJR@VE3MGQ.#SWO.ON.CAN.NA ------------------------------ Date: Wed, 22 Feb 95 23:25 EST From: John C. Fowler <0003513813@mcimail.com> Subject: Re: Peculiar Callbacks Received In TELECOM Digest Volume 15, Issue 113, D.J. Martin wrote that he was receiving strange messages on his answering machine (such as outgoing intercepts and live operators) and that once he even answered his cellular phone only to hear his home answering machine. Pat attributed it to pranksters with three-way calling. I just wanted to point out that these kinds of things can happen even when someone isn't trying to play a joke on you. It happens innocently if the caller is behind a PBX with a call transfer function activated by flashing, dialing a number, and hanging up. How is this innocent? Think of this situation: Caller dials D.J. at home and gets his answering machine. "Darn, he's not at home, but wait, I know his cellular number, so I'll see if I can reach him there!" Caller pushes the switchhook with his finger, so that he thinks he hung up on the answering machine. In fact, he didn't wait long enough, and the PBX thinks it was a flash, so it puts the answering machine on hold. Caller dials D.J.'s cellular phone, but just then, the boss walks in, so caller hangs up just as D.J. answers. PBX transfers D.J.'s answering machine to D.J. Yes, this does happen! It happened to my office-mate at my previous employer, who once had the pleasure of receiving a voice mail message from his home answering machine. John C.

There's one other possibility which comes to me after having listened to a few too many "please hang up and dial again" intercepts on a friend's answering machine: single-tape machines sometimes take more than a minute to fast-forward from the outgoing message to the point where they can start recording. If the caller has hung up during that time, of course, you'll get dialtone and eventually an intercept. However, some single-tape machines also play synthesize "musical hold" while zipping forward; I wonder if there's equipment somewhere (like the old women-and-voicemail problem) that could be trying to make sense of the musical-hold tones. Probably manufacturers have picked their frequencies to avoid this, but it's not entirely implausible. I'm just tossing this out for thought on bizarre feature interactions; Pat's hypothesis is far more likely. paul ------------------------------ From: dannyb@panix.com (danny burstein) Subject: Re: Peculiar Callbacks Received Date: 23 Feb 1995 11:42:15 -0500 A very possible answer to this problem: Does your cellular phone have an auto redial button? Of course it does. There's a good chance you hit it and called your home again. Note that this scenario is also a RISK. In addition to the costs and confusion involved, a subscriber to RISK DIGEST described how he had sat on his phone while at a confidential meeting and the next fifteen minutes of super-secret discussion were recorded on his answering machine. dannyb@panix.com (or dburstein@mcimail.com) ------------------------------ From: msb@sq.sq.com (Mark Brader) Subject: Re: Weird "Prime Number" and Other Messages 800 Number Organization: SoftQuad Inc., Toronto, Canada Date: Thu, 23 Feb 95 03:13:15 GMT CID Tech/INSG (dreuben@netcom.com) writes: > What I got was: " The number you have reached, 6 7 7 - 4 4 4 4, > is not a working number.

For those not familiar with the program, points are awarded to AT&T residence subscribers who have enrolled in the program at the rate of one point for every dollar spent on AT&T long distance each month. Any month (starting in May) that you spend more than $75 per month on AT&T long distance calls you get two points for every dollar. All domestic and international calls carried by AT&T count toward this program including calls made with an AT&T calling card. Exceptions are calls which are billed direct rather than through a local telco, and calls to Alliance 700 Teleconferencing. Those do not earn points. Neither do long distance calls made from cellular or marine phones, or calls to 900 Multiquest numbers. Other than that -- basically, all your regular, routine long distance calls via AT&T from your home phone which are billed by your local telco count toward True Rewards. In addition to point-per-dollar rewards, there are other ways to earn rewards: If you move, notify AT&T of your new address and phone number; you get 100 bonus points. If someone signs up for AT&T residence long distance service and gives you as the referral, you get 300 bonus points. Points can be redeemed at any time when you have at least 100. They can be redeemed for various things: $5 credit toward your AT&T bill for every 100 points. (You get those 'pay to the order of the telephone company' credit slips to redeem with your phone bill.) If you prefer, you get $5 cash back for every 100 points or you have it credited to your AT&T Universal Visa or Mastercard instead. (They send you a check in your name.) You can also have $5 for every 100 points credited to your paging/messaging service account with McCaw, Interlink, Airsignal, Telepage Northwest or Vegas Communications. Five frequent flyer miles on Delta, United, or (god forbid! I don't want to die yet!) US Air for each 100 points is another option. Disney is in on this also, and points can be redeemed for service from the Disney Channel or their catalog. One thing AT&T stressed was that 'point pooling' is allowed, and encouraged. All you have to do is tell them you want to transfer your True Rewards points to someone else; they'll be happy to do it. They said having two or three people sign up for AT&T residential service (300 points each) along with transfer of points from people who have collected them but are not interested in redeeming them could 'result in someone having hundreds, or even thousands of points in a very short time ...' The thing which appeals to me is the credit on my local telco bill and here is how YOU can help: If you have been meaning to possibly send a donation to the Digest but have not gotten around to it yet -- or maybe you just don't have the money to spare -- then you can use this round-about way of helping instead. If you intend at some point in the near future to sign up for AT&T residential service, do it through this special phone number: Call 1-800-383-6158. The representative will switch you to AT&T for free and enroll you in True Rewards. Give the representative REFERRAL NUMBER : BY-6195039315666. Tell the representative to apply the 300 bonus points to that account. Everytime someone switches to AT&T in this way, I get the points. Got more than one line at your place? Feel like giving one of them to AT&T? If you are not interested in participating in True Rewards but got a statement recently from AT&T with your point balance shown you can also help. Mine arrived by bulk mail today so I assume there are lots of these in the mail now. Do this: Call 1-800-869-9900. Tell the representative your True Rewards account number which is printed on the bottom of the statement they sent you. Tell the representative to transfer all of your points to my telephone number 708-329-0570. As the points come in from new subscribers to AT&T who use my referral number and as points come in from transfers out of accounts where they are not wanted, I'll redeem them for credit on my always high, frequently delinquent phone bill. (I haven't gotten cut off once yet this year, I'll have you know! Not only that, since I got my last 'deferred payment plan' agreement finished a few months ago I am eligible to stall by starting another one if absolutely necessary.) If you do sign up using my referral number or transfer your unwanted True Rewards points, please send me email and let me know so I have an idea what's going on. You have to call the two numbers shown above to do all this; the regular representatives on the published numbers they use can't handle it. Thank you very much!

Autonomous registration is a feature built into the standard, but there is no requirement that carriers use it. For several years in the beginning, it wasn't used. Perhaps Airtouch in LA doesn't use it because of the overhead that would be taken up in a system composed of small cells and lots of phones. > 3) What would be the typical amount of time between auto-registration > requests on most cellular systems?

A page is sent out over the control channel IDing the addressed phone. This could be done over an entire system more or less simultaneously, or it could be done over sub-systems, or it could be done cell-by-cell, depending on the system engineering and whether the switch has some idea where to look.

The process essentially identifies the mobile and/or gives an indication as to it's status within the system to the MTSO. Registration occurs when a call is originated by the mobile (sending "access information"), or without user intervention at initial powerup and periodically while the mobile is within the coverage area and turned on ("periodic registration" -- some people use the term "autonomous registration"). Whether the registration is periodic or not, the mobile sends access information. Amoung other things sent on the reverse control channel during registration, the mobile sends MIN, ESN, SCM (Station Class Mark). On a mobile originated call, dialed digits are also sent. Periodic registration is optional; a flag is set in the overhead message on the forward control channel that informs the mobile whether or not it needs to perform periodic registration. Periodic registration is further specified as to whether radios in their home service area (REGH field in the overhead message) or roamers (REGR field in the overhead message) need to perform periodic registration. In order to avoid periodic registration attempts by all mobile subscribers at once, a certain procedure is used to determine when the mobile should perform the process. Upon powerup, the mobile generates an initial random number in it's internal registration register which determines it's initial registration attempt. After the mobile performs the initial periodic registration, the registration register in the mobile is incremented by a constant value in the overhead message ("REGINC" field), sort of like a clock. Included in the overhead message is the field REGID, to which the mobile compares the value of it's internal registration register. When the value of the registration register reaches the value of REGID, periodic registration occurs. Typical periodic registration times vary by systems and is determined by software setting of the REGINC field. I think it's usually around 20 - 30 minutes.

It appears that First registration is no different on AMPS or NAMPS or even IS-54 TDMA. They all fundamentally use the AMPS control channel signalling protocol. > 1) Does the individual phone transmit it's MIN/ESN pair on powerup after > finding an appropriate control channel? It does not have to. The mobile station will only register if it needs to The need is defined by the data broadcast on the forward control channel. The specific data that the mobile looks are are the SID (system ID) and the REGID (registration ID). A new SID will cause the mobile to register and if the REGID is far enough away from the last value recorded in the mobile it will register. > 2) If indeed the phone transmits it's ID upon powerup, why is it apparently > ignored by some systems (AirTouch in Los Angeles)? I can't answer this without more specific information. What symptoms are you observing that would lead to this conclusion? > 3) What would be the typical amount of time between auto-registration > requests on most cellular systems? (I know this varies on system usage, > software, etc. but would like a "ballpark" number). There can be fixed or area registration, which will cause the mobile to register only when it moves into a new area. There is also time base registration which will cause the mobile to register periodically. I have seen systems use intervals in the range of 30 minutes to several days. > 4) How exactly does the cellular system request an ID from each phone > and keep it orderly? (IE..does it go by ESNs? How are collisions > prevented from multiple phones? etc.) Collisions of what ? The ESN is a value assigned by the manufacturer of the unit. The MINS are controlled by the operator.

All phones even the oldest should support registration. If not then get a new one. :-). If the phone can not register and the system "loses" the phone any mobile termination attempt will typically be directed to an announcement. The alternative would be a broadcast page to all areas of a system. If you get lost, make a call from the mobile to any phone and this should reregister you in the system.

I'm an electrical engineering student preparing for my first interiview with my first big telecommunications company. I was wondering if anyone could give me a simple description (or complex if you have time) of what a DMS Switch is and what it does. What does DMS stand for? What kind of maintenance and software is required to maintain it? If anyone could answer these or other questions it would be greatly appreciated ( and it might even get me a job :-) )! D. Andrew Vardy Faculty of Engineering, Memorial University St. John's, Newfoundland, Canada [TELECOM Digest Editor's Note: Actually, you are getting in during the middle of a thread which began a few days ago about the DMS-100 and perhaps the final two messages in this issue of the Digest will give you the information you are seeking.

For ISDN: DMS-100 switches require SPIDs (Service Profile IDs) for ISDN lines. #5ESS do not require SPIDS. Also ISDN TAs usually need to know what type of CO they are "talking to" so a TA reconfiguration may be needed.

We have notived that for BRI ISDN TAs, the DMS-100 switch is a little different than the 5-ESS. Product that meets NISDN-1 and works on the 5-ESS needs to have a few more changes to work with the DMS-100. I talked to a customer yesterday that is implementing ISDN that also noticed that it was harder to shake out service on DMS-100s. So, I can't say that it would be the same for POTS type service, but clearly there are some concerns. For critical applications, I would not ignor the warning. For casual use, you have time to work out problems as you find them.

This is a VERY positive move, as it now makes CO/NY competitive in almost every way with NYNEX/NY, if not unquestionably superior in terms of coverage, automatic call delivery, and customer service. Cell One/NY used to asses an airtime charge for any incomplete call over 40 seconds. I've never been a big fan of such policies, especially since they will result in charges when you try to hear a referral for a changed number (e.g, "The number you have reached, 5 5 5 1 2 1 2, has been changed. The new number is..." etc.). If you wanted to hear the new number a second time, which is a good idea especially when calling from a carphone with all the distractions, then you would go over the 40 second limit, and were assessed an airtime charge. One of the few reasons I use BAMS's B-side service (NYNEX in NYC) is because they did not charge for incompletes, and there were cases in which this saved some money. In addition, CO/NY reiterated that they have eliminated daily roam charges for roaming anywhere in the US or Canada (credit for which, I will admit, must go to NYNEX since they instituted this policy first, regardless of whether such an offering was was "planned" by CO/NY or not). They also noted that monthly service charges will now be billed AFTER the month is over, not before. Overall, very good news indeed, and as a result I know that when I am in NY I'll be using the A side a bit more often now that I don't have to worry about incomplete calls!

TelRoute Communications, the alternative LD carrier with a bad attitude toward Bell (it owed us $3.5 million at the time it filed under the Bankruptcy and Insolvency Act on January 13 for protection from us and other creditors), has signed over its 30,000 customer base and switches to Fonorola, the Montreal-based LD reseller. Fonorola did not pay a specific price; it will pay royalties based on earnings derived from the customer base for the next 36 months. Bell has converted TelRoute's customer base to Fonorola's network as called for in the agreement approved by the Ontario Court on February 8. In January, Fonorola acquired certain assets of Northquest Ventures, including the customer base of LD reseller ITN Ltd. and other subsidiaries.

BCE holds a stake in two of the three rival consortiums which won licences from the U.S. Federal Communications Commission to launch new satellite systems that will offer worldwide, wireless phone services. The three winners are: Motorola Satellite Communications Inc., Loral/Qualcomm L.P. of New York and San Diego, and TRW Inc. of Cleveland. Teleglobe, owned 24.4 per cent by BCE, is a partner in TRW's Odyssey satellite program, and BCE Mobile Communications, owned 65 per cent by BCE, is a partner in Motorola's Iridium satellite program. The three consortiums each plan to spend several billion dollars to launch large constellations of small satellites into low and medium Earth orbit, hence the terms LEO and MEO. LEO systems, like Iridium, will comprise a string of more than five dozen satellites hovering 800 kilometres above Earth. MEO systems, like Odyssey, will ring the planet with only 12 satellites, but at an altitude of 10,000 kilometres. Conventional communications satellites, much larger and costlier, orbit 37,000 kilometres above the equator.

Mountain Dew??? Do you > remember that obnoxious commercial on television a few years ago where > the ignorant hillbilly stands up and shouts, "Yah hoo!!!

And since there are no cola beans (where caffiene naturally occurs) used, it is all added. But, wrong forum. (Interesting to watch these threads ravel, isn't it?)

Regards smoking, my rationale is if I were to quit today, and then twenty years from now die from lung cancer anyway, I'd be mad as hell about it and feel that I got cheated; better not take any chances. :) I started smoking when I was 13 years old because a one of my teachers in school smoked. I'd see that package of cigarettes in his shirt pocket and watch him smoking -- not in school of course, but when we went on field trips or when I went to his home to see him (I was always a teacher's pet, all through elementary and high school) -- and it occurred to me it must be the thing to do. After all, Arthur Erickson was very sophisticated and intelligent, and I wanted to be sophisticated and intelligent also. He taught the current events class (in those days many high schools named the course 'Modern Problems'), was the Debate Team Coach, played the piano and organ marvelously, had some great, and sometimes very unkind remarks about President Eisenhower, and subscriptions to {Atlantic Monthly}, {Harper's Magazine} and the {Christian Science Monitor}. He smoked a pack or more daily, and it didn't seem to hurt him any. Now, forty years later I do it out of habit. I can't imagine *not* being addicted. Unlike some smokers, or the tobacco companies, I don't make any pretense of it being a 'choice', yet on the other hand, I don't really want to quit.

Actually, the public has the *legal right* to be protected, that they are calling who they think they're calling. That is the function of trademarks - to protect the consumer. Beyond which, these are now corporate-owned products, services and brands - not "phone numbers." That's why MCI trademarked 1 800 COLLECT and 1 800 CALL INFO. While certainly still a gray area, 800 portability, local portability issues, 500 "your's for life" numbers and the recent FCC "wish list" musing to auction 800 vanities, all point toward the trend in user proprietary rights, and away from telco control. Telco's complete the calls and bill for that service, but it is monopolistic, anti-competitive and anti-business to attempt to control the brands, media and products -- except of course, their own, as in the MCI illustration above. > {Chicago Tribune} columnist Mike Royko has complained several times > in the past about how his internal centrex number at the newspaper is > the same as a very commonly used number by AT&T for customer service, > minus the 1-800 on the front.

How do you accomodate idiots and fools short of > stopping the world and letting everyone get off? This is not an applicable scenario. Mr. Royko's internal centrex number is not infringing on any trademark. And while I'm sure it's quite annoying to him, since his is not an 800 number, he is not stuck with charges for misdialed calls to AT&T's 800 number. However, both 011 800 COLLECT and 1 888 COLLECT would likely be used, or attempted to be used (or leveraged) as advertised toll-free numbers, specifically to capitalize on the brand equity and recognition that MCI has vested in the COLLECT brand. And, the businesss that inadvertently have similarly spelled or numbered 888 numbers would incur huge misdial bills. Large corporate users could absorb this loss. Given the popularity of this number, most smaller businesses could not. > Do you propose that when the 800 number supply is exhausted we just > quit having any more? Given the real estate, media and brand value in 800 numbers, as clearly lead by the carriers themselves (800 COLLECT, 800 PICK ATT, 800 THE MOST, etc.), I propose (among many other viable proposals I've seen), that: (a) 800 numbers be used only for commercial business purposes, with another toll-free XXX assigned for residential use with no brand ramifications; (b) that beepers and other products be similarly removed to again another toll-free XXX, with no brand interest. These two moves could significantly replenish the supply rather quickly, and should be considered by all interested parties. I'll also go out on a limb here and say that the impression of an 800 shortage is *quite* exacerbated by the carriers' grossly inefficient method of allocating toll-free numbers, and their practice of hoarding 800 numbers. > Do you propose that international commerce and trade be handicapped > by having no uniform way to dial around the world with the charges > reversed to the called party automatically? Absolutely not. Without repeating the entire international freephone thread that's run thru TELECOM Digest, we've seen many worthy alternatives suggested that would fill this need -- without compromising U.S. brands owned by U.S. companies, *or* European brands owned by European companies. These alternatives would provide better protection for consumers' interests as well. > You use FLOWERS as an example, and apparently would restrict the use > of 356-9377 where any other 'toll-free' numbering scheme is concerned > because the Americans got it first and want to protect their brand > name. That is all well and good, but 1-800-FLOWERS is not the same as > 011-800-FLOWERS or 1-888-FLOWERS. From a trademark standpoint, our legal experts say it is potentially indeed the same. As a practical matter, a 1 800 FLOWERS competitor using 011 800 FLOWERS domestically as well as internationally would cause grievous damage to 1 800 FLOWERS. Imagine how much more adversely this would affect smaller businesses. > Needless to say, its not the same as any local area code plus > 356-9377, and yet day after day that number gets calls for FLOWERS by > people who forgot the 1-800. Those callers have not been mislead by false advertising that they are calling 1 800 FLOWERS. Nor is the user of 356-9377 getting billed for those misdials. > There is a practical limit to how much can be done to idiot-proof > the phone network. We are all for exploring the practical limits. But as long as "phone numbers" are treated only as mechanical conduits, no realistic market driven exploration can take place. The brand, product, and media realities need to be addressed. This can only happen when users (both end users and services industry users), as well as brand, marketing, advertising, trademark and other experts are actively involved in the standards processes. > Well that would put us right back where we are now, with an > increasingly limited supply of available numbers. As I've noted above, we are *told* that the supply is dwindling.

Actually, I'm mostly involved with and interested in small business and entrepreneurial interests. While happily acquainted with a good many corporate users, once they're informed and involved, they and their deep pockets can take care of themselves. It is *exactly* the smaller business user that will be crushed by the damage these new standards will cause. > You may not recall, but the same kind of arguments you are > presenting here came up twenty or more years ago as AT&T began major > expansions of 800 service as it was configured back then.

As you know, even if you use your 800 number only locally, you have the option to expand nationally and to Canada. There are good reasons for that. Those good reason do not stop at our borders. Thanks for the chance to clarify some of my thoughts. Judith Oppenheimer, Producer@Pipeline.com Interactive CallBrand(TM) [TELECOM Digest Editor's Note: If I understand correctly then, small 800 users like myself would be forced off that code in order that the numbers could be freed up for business customers. People with pagers and messaging services on 800 would be required to give up their 800 number for the same reason; so that business users would not have to be inconvenienced. I've a better idea: Let's take 888 and have all business users of 800 move there; you can have the whole thing, and it should last you for several years. And you say your legal experts are claiming that 1-800-FLOWERS and 011-800-FLOWERS and 1-888-FLOWERS all amount to the same thing from 'a trademark standpoint'. That's like McDonald's trying to claim they have the exclusive right to use "Mc" in advertising. They do try it occassionally, but sometimes get beaten up. I could see where they might have a better chance where fast food is concerned, however. Generally you can always find a lawyer to say whatever you want. I agree that portability is largely eliminating the old rule of telco which was 'the subscriber has no property rights in his number' but even so, in the three examples given above, the only part in common is the word 'flowers'; that's only seven out of eleven (or thirteen) digits, in other words 54 to 64 percent of the total expression. Can you claim to control any and all uses of the word 'flowers' where it appears in a phone number? Suppose for example I got 1-708-FLOWERS and advertised it that way. Its a perfectly legitimate number when stated as 1-708-356-9377 (or presumably as some other word made from those letter combinations), but as soon as I advertised FLOWERS your lawyers would get after me, I suppose because even though the final seven digits make up only about half of the total expression, they are the 'significant' or 'meaningful' part. Now why couldn't they do the same thing with 011-800 or 1-888? When someone with one of those tries to advertise as FLOWERS in the USA (or wherever your trademark rights extend) then you pounce on them for it. They can use it in Europe or Asia if they want, but they can't phrase it in that way in the USA, where they would have to be 011-800-356-9377. If your lawyers tried to claim that by using it as FLOWERS in Asia I was causing grevious damage to your USA-based business, my response would be to require you to produce records for the past few years showing how much or little of your business came from Asia using your toll-free number.

[TELECOM Digest Editor's Note: Actually I was thinking if they pay me enough, I might pre-empt all regular programming in this newsgroup and provide exclusive OJ trial coverage instead. That whole thing is a joke; I bet it goes on for another year. What a travesty of justice! I don't care if OJ is guilty or innocent. What other person ever on trial in this country has gotten his posterior kissed the way OJ has? Did you know that in the jail where he is being held, all the other prisoners have lost their visiting rights on weekends; that's so that Mr. OJ doesn't have to have riff-raff around him when *his* friends come to visit and his attornies. The jail employees are being extremely unfair to all the other inmates while they suck-up to OJ. Someone should tell him, hey you are just a prisoner here, just scum like all the others ... he should not be getting any more or less privileges than anyone else in that jail. I wonder if/when he is found guilty if they will have to purchase some elegant resort and turn it into a prison where they keep him? I mean, how could they put him in San Quentin with the other murderers? Would his attornies permit that? And Judge Ito sits there and plays the role of straight man in this comedy routine. The whole thing is a good example of how the rich and famous and their high priced attornies get one brand of justice in the USA while the rest of us get something totally different. If it was anyone else at all, this trial would have been over with weeks or months ago; probably finished the day it started or a couple hours after it started.

That's what I was thinking, but it doesn't solve the problem of not knowing that someone called. I don't know whether the phone company has this, but at my office we have a feature in our voice messaging system called out-call notification. You can program the system to call you at another number whenever the system takes a message. I entered my beeper number as the out-call notification number, so whenever anyone leaves me a message I get beeped. This way I always know when someone is trying to reach me and I don't have to give out my beeper number. Does anyone know if the phone company's message service has this feature?

Date: 23 Feb 1995 19:32:11 GMT Organization: Siemens Rolm Communications, Inc. Reply-To: murrays@clipper.robadome.com Hi, I was wondering if anyone had any info on SMR -- Specialized Mobile Radio. I have been approached by a company in Florida to buy an SMR channel. The channel is in the 851-866Mhz range and is used by companies to provided cellular like service at a cheaper rate. The channels are supposedly given out by the government on a first come first serve basis, but this company wants to charge by $3500 to file all the paper work and guarantees me a channel or my money back. Supposedly once you have a channel you can rent it out or sell it to the regionaly operators and they are very anxious to get these extra channels. The have been able to convert these old style radio dispatch towers into digital towers that provided phone, paging and fax service at a fraction of the cellular cost and the towers cover a larger range. My questions are these: Is this really a good investment? Are these channels really in demand by companies like Nextel, CenCall, DialPage etc.? Is it worth going through this company or are there cheaper ways to get a channel? Any information would be greatly appreciated.

PAT] In this area (DC Metro), there are a _lot_ of people with scanners, a great majority of whom are "techies" working for various beltway bandits. There are a few Bulletin Boards dedicated to it, and a local USENET newsgroup. Since cordless phones are about the second thing covered in most scanner books (right after airplanes), I wouldn't call scanning the band "sophisti- cated". Remember that when most scanner books were written cordless moni- toring was perfectly legal. I'd say it's pretty much a given that in most areas of Northern VA, Suburban MD, and parts of DC, odds are that there are scanner owners listening in. In an apartment building, it doesn't even take a decent antenna, and range can be quite good if you have an apartment in a fairly tall building, a dec- ent antenna, antenna amplifier, etc. As for hopping channels, it won't do you any good, as anyone who wants to listen in will be scanning the whole cordless band, not just one frequency. My advice would be to get a cordless that encrypts, and never use a cordless for something like ordering with a credit card, or talking about something you wouldn't tell the cashier at the local grocery store.

While I am falling behind on this issue, until recent months, scanners, both hand-held and base station varieties were sold through legitimate vendors such as Radio Shack that can receive all cordless frequencies and with minor modifications, cellular frequencies. I believe many models receiving cord- less are still available. It has been my understanding that at sometime in 1994 it became illegal for manufacturers to sell scanners that were "easily" modified for cellular (with an exception that allowed depletion of existing stock). It has also been illegal to listen to cellular for awhile. It is my understanding that as of late 1994 a new act also made it illegal to listen to cordless. I do not believe it is yet illegal in the land of the free (except in certain local jurisdictions) to own equipment that receives these frequencies even if it is now illegal to listen to them. For a complete thorough discussion of this topic on a daily basis, please refer to the usenet group: rec.radio.scanner Let me point out that many laws seem to be broken regularly. To the best of my knowledge it is illegal to exceed the posted speed limit on roads and highways, yet it appears that that law is broken by many. I would never encourage, assist or support anyone in an effort to violate any law or regulation. I only to note that from what I read and see, and it appears that some communications laws are also being broken regularly. My general advise is that regardless of what protections the laws are intended to provide, I concur with the Editor's advice above: if it is transmitted you should assume it will be received.

And of > those, how many are sophisticated enough to know how to program the > scanner for cordless? The range of a scanner to receive cordless transmissions of 46 mhz phones is apparently several blocks. With a common scanner, and about a ten inch antenna, I am easily able to pick up clear conversations on many cordless phones/baby monitors. By random count, I am guessing that the coverage is quite broad, since I assume that not every house has a cordless phone. The skill required is trivial. If you can program your scanner to receive your local police channel, you can certainly receive 46 mhz telephone traffic. The only bad part is that by comparison to police/fire, it is long winded and boring. You also get to listen to background conversation in the room while the phone is being dialed out, and ringing at the other end. Of more concern is the skimmers who drive around with a cordless phone, just hoping to catch a usable dialtone from your front yard. You would be amazed at the phone bill my mother-in-law managed to accumulate in about six weeks. I suppose that someone discovered that she leaves her phone off the base (some won't work with stray handsets, if the true handset is in the cradle), and then probably sat in their car in front of the house, and placed phone calls to several pricey destinations. My mother-in-law was astonished (a second time), when I set up my scanner, cruised through the ten possible channels, and picked up her conversation in mid-call. I don't think she really believed it until I showed her. Clarence A Dold - dold@rahul.net - Pope Valley & Napa CA. [TELECOM Digest Editor's Note: Cruising for dialtone is something that has gone on for several years. And the cruisers make a note of where they found the dialtone (in front or behind of what addresses, etc) so they don't have to drive around so long looking for the next time they want to make a long distance call. PAT] ------------------------------ Date: Thu, 23 Feb 1995 18:59:42 EST From: David Leibold Subject: The Unintentional Date/Chat Line George Gamester's column in {The Toronto Star} of 22 Feb 95 makes mention of what is believed to be Toronto's first date/chat line ~1960. The thing was, the service was actually supposed to be some pastor's "dial-a-prayer" line. When an apparent revival in the form of a flood of calls was registered, Bell Canada decided to find out how to control the overloading on the system. It was found that teenagers were doing a conference bridge over a busy signal. Thus dates and chats were arranged at the expense of an over-engaged prayer line. After weeks of attempting to exorcise this demon in the network, Bell was finally able to shut off the conference effect. The calls to the line dropped to a trickle, and it turned out there wasn't a big revival in Toronto after all (an inconvenience for which Bell wound up crediting the religious group running the line). David Leibold aa070@freenet.toronto.on.ca [TELECOM Digest Editor's Note: Some time ago a little trivia item here in the Digest discussed the first use of telephone recorded announcements in other than a weather forecast/time of day context. The first one was a dial-a-prayer service which started about 1955 on Long Island, NY. I do recall when the Hoosier Theatre in Whiting, Indiana had a recorded message giving movie titles and show times. They were running that when Whiting had manual service. The recorded message was on 'Whiting 1234'. Taking advantage of the ease in remembering a number like that, when I operated my recorded daily newsline messages for about five years from 1972-77 I had the number 312-HArrison-7-1234. But I had more than one line. I had about twenty lines in a rotary hunt. i.e. 1234 hunted 1235 then 1236, etc. When I started, it was an old style stepper switch, so I could not have all the numbers I needed since there were not that many idle numbers in a row. When the CO changed to ESS in 1974, I did an expansion with quite a few more lines since it did not matter what numbers were involved any longer; 1234 stayed as the lead. I did not give prayers or scripture readings on my line. The machines I used were leased from Illinois Bell; they were *big*, *heavy* (75 pounds each?) machines used by Bell as for intercept type recordings. Inside they had big round drums coated with mylar which spun around and around as a finger dropped down and touched the surface. They held up to three minutes of recorded information. For recording purposes, one machine was a 'master' and the others were 'slaves'. Little mechanical counters on each line kept track of the number of calls received. Bell said when they set up the 'master/slave' arrangement for me they had to write a special tariff for it; nothing like that had been done with recorded messages previously. I had a little closet-like office downtown where all the machines sat stacked on shelves along the wall.

Over the past few weeks, Open Communication Networks and BellSouth Telecommunications have been assisting CNN on putting together a segment on ISDN and its use for telecommuting. BellSouth Telecommun- ications provided the ISDN lines to CNN and to Miles O'Brien's home (the host of the show). OCN provided the integration of all computer, communication, and software components to give CNN the applications they asked for -- for the record -- in a very limited timeframe. At this time, we are not certain what exactly will show up on the segment of this half-hour show. We have been told that a follow-up is scheduled which will include more standard telecommuting applications than this individual segment is focused on. We are very interested in receiving any feedback about the segment so that we may pass it on to CNN. We hope to continue the series on a more regular basis bringing to the show additional applications of ISDN both on the "bleeding" edge (as some of these were) and more generic applications for use by the general telecommuter and ISDN end-user. Please send any comments or suggestions via e-mail to feedback@ocn.com. The show airs at 11:00 a.m. EST on CNN this Saturday (2/25). It is repeated on Sunday at 12:30 EST. Actual times may vary across time zones so be sure to check your local listings for Science and Techology Week. The applications which were taped for the show include the following: 1) Video Conferencing via ISDN with Intel's Proshare Package 2) Intel's Proshare Premier (shared white board) during #1 3) WWW access via IBM's WaveRunner and FTP's Explore On-Net Software 4) Internet E-Mail via ISDN FTP's Mail-OnNet software 5) Video Conferencing via IP (using OnNet 1.1) over 128K ISDN with Invision's Software and Intel's Video Capture Board - ISDN was via a Gandalf 5242i Bridge (without compression). 6) Internet Phone via ISDN (in conjunction with Invision Video Conferencing 7) WWW at 128K using Spyglass Enhanced Mosaic (next release) via Gandalf's 5242i Bridge (without compression) 8) cc:mail (CNN's internal mail system) via nfs via ISDN through the Gandalf 5242i Bridge (without compression) connected to OCN's Metropolitan IP/CO and then routed to a Livingston's Firewall Router connected via a Bonded 128K connection using Motorola's UTA220 Items #1 through #4 were taped at the home of one of BellSouth's employees. OCN provided FTP's software and assisted in the configuration and implementa- tion of the WaveRunner on an existing ISDN circuit which also served the Intel Proshare equipment on a limited S/T bus. Items #5 through #8 were configured, implemented and installed by OCN. All connectivity to Internet for the program was provided by The INTERNET Connection, LLC in Atlanta (404-419-6100 or sales@ticllc.net) We have been asked to provide {CommunicationsWeek} with a story about how the technology was integrated for the show.

Date: Thu, 23 Feb 1995 22:57:08 Organization: Sulis Computing Help, I'm working on an IVR system that is heavily dependent on Caller-ID to identify callers to the system. We arranged to have our lines put in, and I was shocked to find out that if I wanted a single 1-800 number to access the system, I had to set up the two lines that we needed in the local office as equivalency lines, and that as equivalency lines I would only get caller id on the first line of the group. Unfortunately I could only talk to a local order taker, who couldn't explain to me technically why this is the case, and they were unable to suggest any work arounds and were unwilling to pass me on to anyone technical to discuss the issue. I know the Caller-ID information is transmitted between the first and second ring to the line. For some reason, if the first line is busy, then the second line can not obtain the Caller-ID information and pass it down the local loop to the subscriber at the end of the line. Questions: 1. Can anyone out there obtain Caller-ID information for all lines of an equivalency group, from their local phone company? 2. Can anyone provide me with a technical information of what's happening in the switch that does not allow Caller-ID information to be transmitted in this case? (or a contact to someone within Bell Canada that could answer this question) 3. Any suggestions for an alternate method of having a single 1-800 number pass over to multiple local lines, with Caller-ID information provided to all of the multiple lines. Thanks for any help anyone can provide. This system is being used to provide information to clients with sensory disabilities, many of who will have vision impairments, thus we want to set it up so they have to press as few keys as possible on their telephone to use the system. Paul Chehowski paulc@hookup.net Sulis Computing ad771@freenet.carleton.ca [TELECOM Digest Editor's Note: Well I don't know about the telco where you are located, but here, Caller-ID gets passed just fine to the various lines in a hunt group. For example I have CID on by my lines. The first line hunts to the second when it is busy. I have one CID display box fed through a Radio Shack automatic line selector switch. That's the device that when a single line phone is plugged in, either of two lines ringing will toggle the internal switch in the box and feed the ringing line to the single phone. Instead of a phone, I feed my CID box from that unit. (I have a two line phone nearby.) When either line rings independently, the box shows the number. When the main line is busy and it gets a call the second line rings of course, and the CID box shows the number. So I think someone at your telco misled you, unless they have software that's different than everyone else. Now you *do* have to pay for CID on each line; you can't get by with paying for it just on one line; maybe that is how the rep misunderstood you. Based on the way your message read, I assume you are subscribing to some long distance carrier which supplies ANI in the form of Caller-ID when you get a call. If your telco still persists that they cannot send CID intended for the first line on to the hunt line as needed, then go back to your LD carrier and have *them* supply the hunt group in the form of two 800 lines; one to each of your two numbers. Have the LD carrier make your listed 800 number hunt to a second 'overflow' 800 number and do the work at that end. The first 800 will feed your first line and the second (transparent to the user, hunted) 800 number will feed your second line. Then tell your local telco: two lines, each separate; two Caller-ID's, one on each line. Your LD carrier will fix things on his end so that instead of a single 800 number handled like DID which just splashes all over the place, feeding you to the extent you can handle it, your 800 will handle one call, and one call only at a time. When its in use, the next incoming call hunts to another 800 and it in turn handles one call, and one call only, directed to your second line. Long ago, before having single 800 numbers for lots of calls at one time, we had to do it that way; literally an actual 800 number for each call we wamted to be able to accept. You want to take twenty calls at a time, get twenty 800 numbers. No more, thank goodness, but it is one way to work around telcos who refuse to take what is handed to them and hunt with full features on their end. You can also get the LD carrier to actually terminate on phones at your end direct rather than outdialing what he gets. You might want to consider that also; cut the local telco out of the picture entirely. PAT] ------------------------------ From: crazer@crl.com (Charles R.

How "easy" is is for the authorities to obtain it? The reason I ask is that it can in Sweden court. Some years ago there was a case of a man being sentenced to jail on the basis of his cell-phone records. He had burglered a house but pleaded not guilty. He had an alibi which stated that he hadn't been within 5 km from the burglered house. The police knew that he had a cellphone mounted in his car.

A couple of years ago your location could be computed to a couple of hundred meters square or more. Now that distance has shrunk dramatically due to the shrinking size of radio cells. In just couple of years your cellphone will give you away just as effectively as a (civillian) GPS terminal. Ethical question; is this god or bad?!

Uh,I know this is a rude question to ask, but > have you some reason to wish they were not? PAT] Pat, I can't answer if Chuck has a reason, but his question does lead to one I am curious about. Let's suppose (purely hypothetically) That I am a former pro football player and part time sportscaster with a promising acting career (Thats promising as in - " I keep promising I'll get better - but I don't"). I have recently been charged with the particularly gruesome murder of my ex-wife and her friend. One key to my guilt or innocence lies in my alibi for where I was at 10:15 at the alleged time of the murder. Unable to challenge this time of death due to the well known "barking dog as a time of death indicator" (a well known forensic legal principal recently upheld in the case of Ted Bundy Vs. Lassie), I am forced to prove I was elsewhere at or around the time of death. Remembering that I placed a call to my loving main squeeze Paula on my cellular phone from my driveway at about 10:20, I ponder whether or not the origin cell on a cellular call is logged and if so, could that information prove that I made the call from my driveway (or at least near enough to originate on the closest cell to my house), and not from my ex wife's neighborhood which is located seven to ten minutes away by car. Not trusting the local police department to investigate (since they seem to be staffed mostly by people whose training and expertise in investigation would instill a feeling of superiority in even the likes of Deputy Barney Fife) I instead turn to the learned subscribers of the noted electronic journal TELECOM Digest. So what do you think? Anyone have any knowledge of the distance between cells in the,say, Brentwood area of Los Angeles? Could the origin cell log help me/hurt me? Does the carrier actually save these logs? Pat, I'm sure this isn't what Chuck was asking about, and yes, I obviously have to much free time.

I will be installing one in March and wonder what I will face. I am running a majority of my 30 locations on a Northern DMS100 Plexar (Centrex) arrangement. Since the Ericsson switch is in another town, we plan to use Tie Trunks to connect the two Plexars and maintain four digit dialing company wide. I've just not heard too many good things about this switch. Furthermore, it does not offer the Custom Rearrangement Service like that available on the DMS100. What a drag, have to issue service orders to change anything. Steve ------------------------------ Date: Thu, 23 Feb 1995 05:19:39 CST From: Steve Bauer Subject: Re: What is DMS-100? Stan, The DMS100 is manufactured by Northern Telecom and is a very popular switch used in central offices. About five years ago, my company was faced with the same situation you are dealing with. The actual biggest shock to our employees was going to a new prefix and we forced them to go from three digit to four digit dialing at the same time. You will probably not have any trouble at all with your modem. Things should actually work better. I have found on the DMS100 we are using, which was installed by Southwestern Bell Telephone, that you do not need to place a coma or pause after dialing the 9 access code. The system reacts fast enough that you can just have your modem dial 9 followed by the desired number. One little trick to remember, and it works both with voice and modem calls is to place the "#" at the end of your dialing string. This will greatly speed up the processing of your call. Without it, the DMS100 is sitting there waiting to see if you are indeed finished before it completes your call. It's not a bad habit to get in to. When you are dialing to another four digit extension on your campus, no need to use the "#", it will ring instantly. You will probably be given some new features and some feature codes may also change. Hope this answers your questions.

What kind of maintenance and software is required to > maintain it? DMS stands for 'Digital Multiplex Switching', which is used to describe Northern Telecom's family of central office switches. Variants of the DMS include the DMS-100 (end-office, POTS and ISDN), DMS-200 (toll), DMS-300 (international gateway), DMS-MTX (cellular), DMS-STP (CCS7), etc. The components of a DMS system have been developed over the years using many different processor families, programming languages, and operating systems, with a common goal of achieving a the maximum call-processing capacity and very high availability. (System downtime targets are on the order of 30 seconds/year) The role of the switch is to process telephone calls. A POTS call is the simplest. The switch monitors for off-hook, provides dialtone, collects dialed digits, figures out who you want to talk to, rings the other line, waits for answer, sets up the voice path through the switching fabric, sets up the call, and then waits for one end to hang up so that it can reverse this process. Oh, and it bills the call, too. (Very important!) And it does all this a couple of hundred times per second. The software that maintains the system is crucial, and constitutes a large proportion of the library, which was counted at 25+ Million lines of code a few years ago. It's a very big, complex, realtime system. It can be a real challenge to keep it all working, and it can be damn hard work, but there's a whole lot to be learned from it. Good luck with the interview. (NT or BNR, I presume?) (Oh, on the DMS-100 thread: I recall reading here that an example of a difference you may find in CO switches is that some let you dial through a stutter dialtone, and some don't. Things like modem dialing strings may need to be tweaked. I imagine the differences in external behaviour would be relatively minor.)

I suspect that the anonymity afforded by the services have a lot to do with the problem. Now that Caller-ID is available in many areas, the "heavy breathers" have to go elsewhere and the net is a natural. My opinion is that we do not need to make context illegal (and with all of the different juristictions probably can't since so much is dependant on "the eye of the beholder". Rather, if the identity of all users were available through something like a "white pages" -- I know there is one, look for the first Peterson -- then I *suspect* that the problem would become manageable. Currently the traditional response -- personal retaliation is difficult. The sad part of this long posting is that female users are being forced to change their usernames for protection. IMNSHO they are being victemized by terrorists -- is there any other word ? -- and *that* is the injustice. On earlier frontiers, those who were impolite had to do it face to face and risked retaliation. The crude cowards of the net hide behind a mask of distance an impersonal electrons and communicate from their closets. Now if I were more mercenary, I could see a value of being able to trace any message to its source. It is certainly doable and not very difficult, just an "unexplored territory" at the moment. However I do think that Internet Caller-ID would be a better solution to the problem than the "thought police" since censorship does nothing to stop those who are rude, only society/culture can do that.

(For > practical reasons, I can't use his line all the time, he runs a business > on it). The usual cause of trouble connecting or staying connected at high speeds is high loop current coming from the pair gain equipment (or right from the CO or a PBX for that matter). If you have a digital voltmeter with a DC ma scale, you should be able to determine your loop current by putting the leads in series with one side of the line, making a call (with the electricity going thru your meter) and reading the ma off the meter. For good data communications, it should read between 23 and 27ma DC. If it's over 27ma, which it probably will be, you will need to get the current down below 27ma. It is not unusual to get 50ma, and sometimes as much as 80ma of loop current. In addition to preventing high speed connections, 40ma and up can burn out whatever you've got connected to the line, except standard old non-electronic 2500 type telephones. If the loop current is between 23 and 27 ma, you are looking at a problem other than loop current. If the loop current is below 23ma, the phone company must bring the current on the line up to 23ma. If it's above 27ma, the phone company won't reduce the current for you, since their high spec is 110ma (a holdover from the early 70's before there was much electronic stuff out there). To bring the current down, you can use 1/2 or 1 watt resistors in series with BOTH sides of the line (the red and green wires). For every 100 ohms you put on the line, you will reduce the loop current by about 1ma. While you reduce the loop current, you are also reducing the AC voltage containing the audio on the line - 100 ohms reduces the level of the line about 1db. If your loop current is at 33 ma, and you stick 600 ohms in series with each side of the line, you will drop the db level from say -6db (which is a good average), to -12db. This would probably work OK for the modem, since it doesn't like real high audio levels anyway, but you would have trouble hearing people talk on the line at that point. You could put these resistors just before the modem -- and NOT in series with with your telephone, which would still allow you to talk. If you have 40ma of loop current, you would need to put in 1300 ohms of resistors, which would lower the db level to -19db at which point even your modem wouldn't be able to hear on the line. We sell a gizmo called a Loop Current Attenuator which has a series of dip switches that you keep flipping until you see the loop current on the line go below 27ma. At that point, you remove your meter and leave the Loop Current Attenuator in place. The Loop Current Attenuator uses a network of resistors and capacitors to leave the db level alone so you or your modem can still hear on the line, while reducing the loop current. We sell the modular Loop Current Attenuator for $32.95. 30 day moneyback guarantee. 708-980-7710.

GSM authenticates the phone and the user (through a SIM card). Also, the digital nature of the signal provides inherently better security from eavesdroppers, and in addition allows the signal to be enciphered. The ETACS system, is _I believe_ a derivative of the North American AMPS system, which is analog. There are various stories around that security and authentication on AMPS leave a lot to be desired. Not only is it easy to eavesdrop on a cellular conversation, but it is also fairly easy to fake authentication, and fraudulently charge calls to your account. There were some posts earlier about channel pirating on AMPS.

[TELECOM Digest Editor's Note: Although I commented on this topic earlier this week and presented a lengthy commentary on the Exon legislation, its worth mentioning again with a suggestion that you take some stance *now* on this matter. If you did not read and sign the petition circulated here earlier in the week, you might want to go back and read it now, along with this similar message sent by the ACLU. PAT] **ACLU CYBER-LIBERTIES ALERT** FIGHT ONLINE CENSORSHIP! AXE THE EXON BILL! The American Civil Liberties Union urges you to contact the members of the U.S. Senate Commerce Committee and your own Senators to ask them to oppose the efforts to turn online communications into the most heavily censored form of American media. In a clumsy effort to purge sexual expression from the Internet and other online networks, the self-described "Communications Decency Act of 1995" (S.314, introduced by Senator Exon on 2/2/95) would make ALL telecommunications service providers liable for every message, file, or other content carried on their networks. Senator Exon is planning to attach the bill to Senator Pressler's new telecommunications legislation, which is targeted for action in early March. The Exon proposal would severely restrict the flow of online information by requiring service providers to act as private censors of e-mail messages, public forums, mailing lists, and archives to avoid criminal liability. The ACLU believes that online users should be the only censors of the content of the information they receive. **The Exon proposal broadens existing law by subjecting service providers, as well as the individuals who actually send messages, to criminal liability for any "obscene, lewd, lascivious, filthy, or indecent" message transmitted over their networks.** If enacted into law, this vague and overly broad legislation could have the following draconian effects: * The Exon proposal would prohibit communications with sexual content through private e-mail between consenting adults, and would inhibit people from making comments that might or might not be prohibited. * Under the Exon proposal, service providers would pay up to $100,000 or spend up to 2 years in jail for prohibited content produced by subscribers on other networks, over which they had no control. * The Exon proposal would expand current restrictions on telephone access by minors to dial-a-porn services to include online access to indecent material, requiring service providers to purge "indecent" material from public bulletin boards and discussion groups to avoid accidental viewing by a minor. In effect, online providers would be forced to offer to adults only that content that is "suitable for minors." S. 314 is nearly identical to an amendment Senator Exon successfully attached to last year's Senate version of the telecommunications law overhaul. Last year's bill died for unrelated reasons, but the Senate Commerce Committee is determined to pass new telecommunications legislation this year that could easily include the Exon proposal. The ACLU opposes the restrictions on speech imposed by this legislation because they violate the First Amendment's guarantee of free expression. Forcing carriers to pre-screen content violates the Constitution and threatens the free and robust expression that is the promise of the Net. The Constitution requires that any abridgement of speech use the least restrictive means available -- the language of the Exon proposal is clearly the most restrictive because it sweeps broadly against a wide array of protected material involving sexual expression. Stop the information superhighway from becoming the most censored segment of communications media! ACT NOW: Urge members of the Senate Committee on Commerce, Science, and Transportation: *To oppose the Exon proposal, or any Senate or House variation. *To drop the Exon proposal BEFORE it goes to the Senate floor. *To hold full hearings on the Exon proposal and to review it thoroughly before it goes to the Senate floor. *To reject any effort to attach the Exon proposal to the Senate telecommunications legislation.

I'm trying to recall the exact wording for MVIP, and I can't find any magazines near my desk with articles naming it. However, I do believe it stands for Multi Vendor Interface Protocol, or something to that effect. Bottom line is that it is a industry standard developed by Natural Micro Systems, a voice processing hardware manufacturer (competitor of Dialogic). It is basically a standard that other vendors can meet, in order to ensure that their equipment is compatible with the NMS architecture. Dialogic has a similar standard called SCSA, hence the big industry battle between MVIP and SCSA (similar to MicroSoft's TAPI against Novell's TSAPI). Yup, that's what it is.

Each employee can only call with their own code and the records show up on the monthly bill. If their calls get out of hand, show them the bill and point out the length of time(s) on their code. Try setting a monthly limit per employee. By the way, these codes must be "validated",(i.e. they use a SPECIFIC number ... say the last four digits of their social security number). Hope this helps!

Modem manufacturers have been slow to provide these drivers because Microsoft distributes a free generic modem driver with the TAPI SDK, because Microsoft distributes the source code for a rudimentary voice modem driver free (by ftp "ftp.microsoft.com" and Compuserve "go winext"), and because Microsoft intends to provide a generic modem driver (Unimodem) bundled with Windows 9x. The problem with these Microsoft drivers is that they are limited, since they do not properly support voice features. Also the Unimodem driver appears to be a "dial only" driver since it does not pass rings back to the application. Regular modems are actually poor candidates for TAPI, since they provide meager call control features. Best for telephony are boards like the IBM Mwave, which allow for full duplex speaker phone, touch tone recognition, Caller ID, handset state detection, control over the handset connection to the line and software upgradability to features such as VoiceView. Somewhere between regular modems and Mwave type cards in terms of telephony features are voice/fax/modems, which can record and play sound from the line, but still provide poor status sensing (like handset on/off hook), and which are intrinsically unreliable for two reasons: 1. the burden of voice data through the serial port and 2. the inclusion of status and control signals in-band in the voice data stream. The first of these deficiencies is addressed by some modems, such as those based on chip sets by Sierra and Cirrus that do their voice with DMA rather than through the serial port. Of course modems using this technique must be internal. Plug: My company, AlgoRhythms Incorporated, has written several service providers for various different hardwares, including a generic modem driver that supports voice modems. This driver is not currently commercially available, though it will be bundled with our application software "PhoneKits" when this is released. ------------------------------ From: bpc@netcom.com (Benjamin P.

If that is so, then when a customer has received obnoxious phone calls, the telco could provide the incoming IDs for particular conversations that have already taken place. This would be much more helpful than the ineffective services that are now being offered. Some person at the telco would have to access a database to provide the record of a past conversation. They probably won't do this for free unless the PUC decides that they should. On the other hand, many customers who have received obnoxious calls are highly motivated and would probably be willing to pay enough to allow the telco to recover the real cost of providing such a service. The telco might even make a profit. This reasoning assumes that caller ID is not available (as, for example, in California) or that the telco records make it possible to identify a caller when caller ID fails to do so. Also, I assume everyone agrees that the privacy of the caller should not be a consideration if a residential customer claims to be receiving obnoxious calls. The privacy of the callee is certainly more important than that of the caller in this case, and arguably so in all cases.

I was unable to get this working on a Supra FaxModem, spending about 20 hours and several email and telephone conversations with the manufacturer. The retailer informed me that many of their customers were similarly unable to get it to work. I went to a ZyXEL for desktop use; I do not believe that they make a PB internal. My advice is to purchase an inexpensive desktop modem for home use. ZyXELs offer "distinctive ring" decoding, which is an alternative to "Silent Answer" requiring "Ringmate" or some other type of distinctive ring service from your local telco. ZyXELs, however, are _not_ inexpensive; if you don't want to go this route call Hello Direct (1-800-HI-HELLO), and order a box from them that will do this discrimination externally and allow you to use any modem you wish.

For example, the yellow pages commercial directories are owned in a consortium with a publisher and several carriers including Bell Canada. And the carrier's pay TV ventures are being run via 50-50 consortia with Microsoft (on-line services) and News Corporation (content). The only analysis on the carrier comes from Moody's which regularly evaluates its credit worthiness. Prospects for the company are good, even though the market will be liberalised in 1997. Although there will be unlimited competition, dominant carriers who control bottlenecks will be forced to offer "commercially-sustainable" tariffs based on network costs.

Ground start IS used today for PBX trunks. Loop start does not work well on PBX because of glare problems, so ground start is used again.

T-1 channel banks are tyipcally optioned for one of the above signaling methods, because they are connected to an analog PBX! The trunk (or line) card coming from the PBX is terminated at a channel bank. The channel bank muxes 24 circuits out to one T-1. The channel bank must use the same signaling as the line card in the PBX, hence the original misconception that these are used for T-1 signaling. Hope this clears up signaling ...

It was in the papers over the weekend. It seems the latest rage on Internet where the mass media is concerned is going to be child porn. If there is a ring going, so much the better, eh? Watch and see if this theme is not going to be hammered down our throats now for awhile until something better comes along. Anyway, the papers reported that three elementary school teachers were arrested on February 17. Their offense was being in possession of child porn and passing it back and forth on the net. Two of the teachers are in Florida, and the other is in South Carolina. The government claims the two in Florida were manufacturing it and sending it to the guy in South Carolina. The two in Florida, it is claimed, were getting young boys to come their homes where they received money for doing the no-no thing on video. This video was then converted into computer files and shipped over the Internet to the fellow in South Carolina. He in turn distributed it elsewhere, to fellow .. umm, enthusiasts via computer. The authorities would not have known about him had they not raided the computers in Florida and found email, etc addressed to him. It seems there were other names there as well, i.e. other members of the ring who received the files showing boys doing the no-no thing and these folks are also teachers. In a thinly veiled threat the investigators handling this case issued a press release saying in part, "We know all school teachers are not pedophiles, but quite a few are ... and we know that many pedophiles select occupations where they can make easy contact with their victims. Based on the additional names found in the computers of the men we have arrested, our investigation will continue with an emphasis on *school teachers who have computers and use the Internet*." Oh wow! Maybe librarians who operate children's departments in their library who own computers and use the Internet should be included in this investigation. It probably would not hurt to include social workers and youth workers who login on the net also. And whatever they do, they should not forget to investigate the youth pastors at various churches. Well, they did not include all those categories ... just school teachers, which ought to send a few chills around the net. This is starting to sound more and more like old Joe McCarthy, a creep most of you would not remember, even if you may have heard about him. McCarthy was a senator from Wisconsin during the 1950's. With the exception of whenever the Senate was having roll call for a vote, he spent the rest of his time all day holding hearings, with the threat of federal subpoena and Contempt of Congress charges hanging over the heads of those who would not cooperate. McCarthy's hearings were to locate and identify 'known communists and homosexuals' employed by the government. He considered them to pretty much be one and the same, although he admitted there were some homosexuals who were not communist and vice-versa. All day long parades of 'witnesses' came before his congressional committee to plead their own innocence and snitch on others in an effort to save themselves. What year was it, 1951-52? The McCarthy hearings went on all that summer for several weeks. Like his contemporary in government J. Edgar Hoover, McCarthy spared no effort to identify and root out 'deviants'. Then at night, after a hard day at work, McCarthy would retire to one of various gay bars in Washington, DC where he would cruise for a lover of his own for the evening ... anonymously of course. Oh, he was a strange one alright. Sometimes if he was in a hurry to get out to the bars, he would adjourn the afternoon session of his hearings early. If you watched the hearings regards the Supreme Court judge and the allegations of sexual harrassment and thought that was funny, then you would have considered Joe McCarthy to be a real riot. About the same time in Idaho, some fellow was arrested for doing the no-no thing in the men's room of the public library, and the uproar over his actions caused the editors of the {Boise Idaho Statesman} newspaper to run an editorial entitled 'crush the monsters'. In it the newspaper encouraged police to identify and arrest all homosexuals. The police took that message to heart, and there followed over a period of about three years in the middle 1950's a *massive* witch hunt for gay men (no one ever told the idiots there is such a thing as gay women) throughout the state of Idaho. And each one arrested took the advice of the police that, 'if you tell us the names of all the people you know who are deviants it will make our job a lot easier'. They were all telling on each other; it was an unbelievable thing. Each one arrested would give still more names to the police, etc. McCarthy used the same tactics: tell us the names of the people you know who are communists or homosexuals; if you make it easy on us we will make it easy on you ... either that or be held in Contempt of Congress. Joe handed out those contempt citations on a regular basis, and the 'witnesses' would always hand over a few more names Joe did not have on his list yet. -------------------- Now fast forward forty years ... the newspapers are banging their drums and talking about all the child pornographers on the net. By the way, I do *not* equate child pornographers with gay men; let's set that straight here and now. How often since the first of this year has a day gone by you have *NOT* read something negative about the net in the papers? -- Mitnick, the infamous hacker captured; -- the kid in Ann Arbor gets arrested for writing threats; with a sex twist to the case of course; -- other hackers and phreaks arrested, stories told in detail; -- and of course the child and other assorted pornographers; the couple put on trial in Tennessee for pornography; -- a lengthy article in (I beleive) the {Village Voice} talking about how people behave themselves in hot chat on the major systems. And more ... there are not many days now we do not read something about the net in the papers, and never is it positive. And now we read that investigators feel more attention should be given to 'school teachers with computers who use the Internet' ... they might be part of a ring involved in child pornography. After all, three have been arrested in the southeast, and they had names of others. Isn't that precious? Gee, you don't think the newspapers have an axe to grind with the net do you? I mean, its not like their circulation has gone down in recent years is it? It doesn't have anything to do with the fact that there are only now only about 20 percent of the number of newspapers in the USA today there were even thirty years ago, or the fact that circulation and delivery hassles are worse than ever does it? Its not like they want to keep their tight grip on the information business and charge lots of money for what most of us get for free is it? So in my opinion, watch the papers keep on banging their drums and having a grand time with every degrogatory story they can find about the Internet and its components. The more they write, and the more erroneous their reports, the more the general citizenry will get in an uproar and demand 'something needs to be done'. And the more the citizens squall, the more the government will be egged on to clamp down on things here. The more the government harasses the net, the more the papers will have to write about. See how neatly it all fits together? Not only that, but the more the citizens scream and the government reacts and the newspapers report, the more the same citizens will be looking for admission to this not-so-exclusive of late club, so they too can share in the alt.sex.stories and other benefits of membership in the club. You watch; this will be the year of the Internet, with lurid reports in the mass media on an almost daily basis before the year is out. A ring of pedophile school teachers operating on the net? My, my, what will they think of next? What's going to happen is the constant abuse of the 'child pornography is so bad, we have to take any actions possible to stop it' theory is going to cause that theory to lose whatever currency it may still enjoy. Yeah, child porn is sleazy stuff for sleazy people; but it is getting to where its like a joke when the government mentions it in connection with some investigation or another. Whatever shock value comes with the announcement 'child porn was found on the net' is going to wear off. *Then* what will be next?

Newcomers to the online world will likely need not only some help with installation, the first few calls, tuning, and troubleshooting, but with an introduction to all aspects of microcomputer communications. An overview of modems does a good job of explaining protocol concepts with real world analogies. A chapter on buying a modem is quite brief, but realistic, as is the advice on software. Chapter five, on setting up your modem, is short and practical. Chapter six, on software installation, should be considerably expanded in order to assist first-time users. The concepts have been explained, in chapter two, but the specifics of how that works out are lacking. There is a good section on identifying COM ports (often missing in other works), but little advice on how to identify incorrect parameter settings. Appendix B, on troubleshooting, does have some advice but it, too, is quite terse. Chapters seven to twelve give you a rundown on what to do with a modem: call a BBS, call a commercial online service, call an electronic mail service, call the Internet, call another private computer, or set up your own BBS. The material on the different types of services is quite reasonable and unbiased, and gives you good advice on what to expect (although the Internet section could use a bit of fact checking). "Remote access", the ability to use your home or office computer from another remote computer, is the only missing application. The last three chapters offer some helpful, related advice on money-saving tips, communications-related shareware, and the communications aspects of Windows. There are also a number of resource lists, including the ASP BBS list, the "Boardwatch 100" list, and communications hardware and software vendors. Those buying and setting up modems for the first time may want additional sources of buying advice and help, but this is very definitely worth consideration as a general advisor and entre to the online world. copyright Robert M.

The Internet Society itself (headquartered in nearby Reston, VA), a global organization, has encouraged creation of DC-ISOC to allow the headquarters organization to maintain a global perspective, while the chapter meets the pressing need for Internet representation in the U.S. government's work to define the National Information Infrastructure (NII). DC-ISOC's other major focus, concerns of the many Internet service providers, and policy and user advocacy groups concentrated in the DC-area "Netplex" (Fortune magazine, 3/7/94), is also a natural direction for a local chapter. DC-ISOC recognizes that several existing organizations, each covering a specific aspect of the Internet, exist. The chapter will provide a mechanism and forum for those diverse interests to interact and advance their goals. DC-ISOC membership is open to individuals and corporations with a strong interest in how the Internet develops, whom it serves, and how it is used. The chapter especially encourages participation by representatives of the many DC-area Internet service providers, public interest and other advocacy groups, representatives of Federal Government agencies, and interested individuals.

According to Junko Yoshida, AT&T will begin selling "a new breed of interactive consumer device that will bring voice, e-mail and fax messaging, together with personalized information services, onto a TV screen" in the second-quarter of this year ("AT&T unveils 'Sage' info center at CES," Electronic Engineering Times, Jan. 9, 1995, p. 10). Yoshida reports that the $329 AT&T TV Information Center, which uses existing phone lines, can store 20 minutes of digital voice messages. Users will be able select which voice message they want to listen to from an on-screen list, and will be able to access topic-specific news, sports scores, local traffic, weather, and interactive services such as electronic home-banking and bill paying. AT&T says customers will be able to purchase a basic package of these services for less than $10 a month. "This was specifically designed as an alternative device for those who choose not to buy a PC at home," says Bell Labs V.P. Eric Sumner in the article. In response to set-top boxes being developed by other telcos and cable companies, Sumner says AT&T's new devices will be positioned as "information superhighway on-ramp products for everyone that can be used today, instead of something useful five years from now." AT&T will also sell a model that connects to a PC and a $199 model that consists of a phone with a built-in screen. Zenith Electronics Corp., through an agreement with AT&T, will begin incorporating the technology into its TVs and cable set-top boxes beginning in early 1996, Yoshida reports. A sidebar on Bell Laboratories' new Plan 9 operating system, which AT&T's product uses, accompanies the article. The new OS has been viewed as a possible successor to Bell Labs' Unix operating system. ------------------------ This story is republished with permission from the March 1995 {Cybernautics Digest}, a monthly summary of reports about converging information technologies.

Jim Chen ------------------------------ Date: Sun, 26 Feb 1995 21:49:44 EST From: Paul Robinson Organization: Tansin A. Darcos & Company, Silver Spring, MD USA Subject: What Are You Doing in the Falkland Islands? I just had a couple of interesting thoughts regarding the new 500 area code in the US: 1. Someone gives out a number like 500-xxx-xxxx and the person getting it says "I thought you lived in Las Vegas? What are you doing, running some kind of phone sex system in the Falkland Islands? (A lot of this is done in the Netherlands Antilles and a few other places.) 2. Someone gets a note to return a call with an area code 500 number and reaches some poor clueless person over in the Falkland Islands. (It probably wouldn't work though; the numbers there are probably only 4 or 5 digits, not 7. It's not a very large place.) (Falkland Islands moved to +500 some time after the war between Britain and Argentina. It was either in 1 809 or was nondialable and required international operator assistance). [TELECOM Digest Editor's Note: It does not matter how many digits the place has. If the number is direct dialable, then it can be used. In most places where the local numbers are less than seven digits, you will find the city code and country code are longer, to fill in the blanks.

An angry look on her face, she says, "I can't believe you'd waste money on such a thing!" Their son has just come in the door and says "uh-oh, what now?". Picture 2: Grandma turns to son, still with an angry look on her face and says, "Your father! Look at these charges on our phone bill!" (Holding out a sheet of paper so the son can see it.) Son says, "900 numbers?" Picture 3: Grandma continues her tirade at Grandpa Nick, who stands there with an embarassed look on his face. She says "I consider it cheating, Nick." Son (holding the phone bill and reading it) says, "Dad, you're calling the smut lines?" Picture 4: Grandpa Nick's eyes brighten up. He looks at his son and says, "Smut? What smut? Those numbers are the crossword puzzle help line." Grandma still has an angry look on her face and says, "Cheater! No wonder you've been using a ballpoint!"

The company was unable to provide interception services to intelligence agencies. According to a Mobilink official "there are no commercial products ... that enable over-the-air monitoring of calls." However it remains unclear why agencies would require monitoring of wireless mobile-to-base traffic, instead of intercepting at the base station. While GSM's digital encrypted traffic may be hard to tap in real-time, it is decrypted at the base station. Earlier in January the network was suspended for two weeks during negotiations.

Chapter one is a good introduction and a breakdown of the mail system into the mail user agent (MUA, called "front end" in the book) and the mail transport agent (MTA). Later parts of the chapter may become too technical in discussions of wide area networks, to no purpose. Chapters two and three give a very good overview of email use and evaluation. The material is broad- ranging and generally excellent, with the notable exception of deficiencies in the coverage of security and file attachments. Chapters four through seven document uses and commands for cc:Mail, MS-Mail, Novell Groupwise, Lotus Notes and Windows for Workgroups. Chapters eight to fourteen cover what is generally the "mail Internet"; BBS networks, commercial services, and the Internet, itself. Except for two sizeable chapters on Compuserve and America Online, the material is quite terse, though an acceptable introduction. Directions and tables of internetwork addressing are a strong point, here. (For a book discussing global email, there is much evidence of US-centrism. This may explain some of the blind spots with regard to security issues.) A fair amount of the book could be discarded with no appreciable loss, and a few points (such as netiquette) could stand some boosting. Overall, though, this is a solid introduction to the topic. And the authors show admirable restraint in not promoting ProComm. copyright Robert M. Slade, 1995 BKUEMAIL.RVW 950124. Distribution permitted in TELECOM Digest and associated publications.

Called 'International Redial' the way it works is after dialing an international call where you did not get through, you just have to hang up a second and dial *234. That will automatically redial your last international call over again, several times for up to thirty minutes. Once it gets through, a message is played in your choice of 14 languages to the party who answers the phone. It tells him to hold on and you are called back and patched through. Nothing comes free: The cost is $3.00 per month, and it only works to about twenty countries at the present time, however those twenty include a few that are notorious for sending back that message saying 'your call cannot be completed in the country you dialed at this time'. To enroll or for more information: 1-800-732-WORLD. Yes, I know you can leave the /D/ off the end if you want.

Our local telephone company is planning a 900% (900 percent) increase in the rate that it charges for a non-published, non-listed telephone number on a monthly basis. And that is on top of the "*67" that I have to dial to stop my number from being transmitted by Caller ID.

Box 4 Apple // & Van Halen Forever! | 21.6k USR Dual Standard | Mukwonago, WI 53149 [TELECOM Digest Editor's Note: I think you will find the various privacy regulations apply more to the government than they do to private businesses. Since telco is a privately owned business -- not a government entity -- it may be hard to apply this as you want. Also there would be a conflict where your contract with telco (as expressed through its tariffs) is concerned. I can see what you are trying to accomplish, but I don't think it will work. Remember also that according to telco tariffs, you have no 'property rights' in your telephone number. It is not, strictly speaking, yours to 'protect'. It will be interesting to hear the results of your investigation and efforts as you proceed further on this, if you do. You should also bear in mind that you can press *67 all you like, but it will NOT prevent subscribers to 800 service (or people who subscribe to 500 service who accept your reverse charge call via a PIN) from getting your number. Likewise, long distance carriers are entitled to have your name, address and phone number *despite your non-pub status* for billing purposes when you use their network.

Until recently, you had to call the seven digit phone number if you needed the police or fire departments. A problem would crop up, as the police's exchange was 262, and 261 also exists in town. Car accident happens at the corner, pick up the phone, and dial the wrong number, cause I could never get it clear in emergencies. Half the time I'd get it wrong. (Note, a rather bad intersection was near my parent's house, not a month would go by without an accident there until they put a blinker light up.) I haven't tried the 911 number, no emergencies have come up, and I don't want to waste their time on my tests. ------------------------------ From: stans@panix.com (Stan Schwartz) Subject: More CellOne/NY Frolics Date: 28 Feb 1995 03:37:34 -0500 Organization: PANIX Public Access Internet and Unix, NYC We've all heard the stories of the "fun" I had trying to use my CellOne NY/NJ phone while roaming in Canada. Last week, I visited some friends on the Inner Harbor in Baltimore. Before I left, I looked at my CellOne Coverage Area map (dated 5/94 - I haven't seen a newer one) and saw that all of Maryland and Delaware and DC are in my "expanded home rate" area, and that there were not any notes or asterisks that referred to the Baltimore area. Wasn't I surprised, then, when I tried to call my CellOne phone from the hotel room and I received my voice mail! (I shouldn't have been surprised!). I called CellOne's 800 number, and the rep told me that even though Baltimore is a NACN city, incoming callers had to dial a roamer access number! (Where does it say that in CellOne's map?). I figured that it wouldn't do any good to argue on a Saturday night, so I asked what the roamer access number was. I told her that I was in Baltimore, in area code 410. She gave me a 202 (DC) number and insisted that it was the closest one! I called back a bit later, and another rep gave me a 410 number. Imagine asking my friends in Baltimore to call DC so that they could reach me if I was down the street. (Almost as silly as asking them to call New York, but at least they'd be able to reach me directly). The first rep mentioned something about the lack of a mutual roaming agreement, and I wonder if this is retribution for CellOne turning off access to roamers in NY? CellOne Strikes Again!

My lovely local GTE switch does not offer call forward on no answer or call forward on busy. Is there any box I can buy for home usde that will give me these features? Thanks, Chris [TELECOM Digest Editor's Note: A service which is identical to 'call forward on busy' is known as 'hunting', or 'jump-hunting' if the number used for overflow calls is not immediatly in sequence with the line which is busy. The only difference between the two seems to be their name, and the fact that most telcos charge for the former but not the latter. Maybe someone will write and tell me other actual differences between these. I certainly would imagine that GTE offers hunting; I have not seen a switch or a CO that could not do that much. You might want to go back to the rep and put it in different words. When your one line is busy, you want to have calls hunt to another line. That will take care of one segment of your problem. Regards call forwarding on no answer (as opposed to absolute call forwarding, where every call is forwarded without giving you an opportunity first to answer; I imagine your telco offers that also), Radio Shack used to have a little box to do what you wanted, and I think Hello Direct currently has one also.

We already get a very good deal as we continuosly shop around. Here is what we are looking for. If you can provide this to us under these terms, email me with the details and I will email you back with the best time to contact me so you can make your pitch, along with my direct telephone number. 1. We are looking for T-1 domestic USA FLAT rates without the T-1 comitt- ment. We have eight lines and want to use them on a non-pic, 10XXX basis. Specifically we require six second billing with six second minimum on all our domestic USA calls (not interested in 18 second or 30 second minimums). 2. We spend around $10,000.00 per month on all our telecommunications and split this amoung around a dozen companies, by choice. We route our calls over the least expensive carrier for each type of call. 3. We do not want a contract tying us down to one carrier. As long as you are cheapest you will keep our business for what you are cheapest on. We want no monthly minimum and no monthly fees and no sign-up fees. 4. To get our business, you will need to be very competitive. We pay nearly T-1 rates now and are looking to get down in that actual range of competitive T-1 rates. We understand that there are several companies offering to beat anyone's rates by 10% and we would like to hear from one of those companies, but not from a company called Affinity or anyone representing them, as a friend had a very bad experience with them. They promised something and then did not come through for him. We will not even consider them. So if you would like to contact us, we would welcome your sales pitch. Note: we are not interested in any of the following arrangements, which have been proposed to us before: 1. Selling long distance to *effectively* reduce our bill. 2. Paying an inflated invoice to get a rebate later. Thanks.

Sven Echternach sec@sec.de ------------------------------ From: Judith Oppenheimer Date: Tue, 28 Feb 1995 11:02:33 -0500 Subject: 800 Numbers: Media, and Real Estate Pat, it's clear, that by employment and occupation, the policy shapers and decision makers regarding all telephone numbering plans focus on the mechanical and engineering aspects of telecom. Valid aspects, to be sure. But limited. These people are employed by the real estate moguls of telecom -- the carriers. For whom this mechanical and engineering (operational) focus preserves their territorial exclusivity. So the ITU, INC. and other participants in these processes, are by design quite removed from the multi-disciplinary, non-telecom market realities of 800 numbers. Two Market Realities: Media, and Real Estate. 800 numbers have solid media characteristics. They contain content and attract targeted audiences. 800 COLLECT attracts collect callers. 800 FLOWERS attracts flower buyers. Etc. This raises very interesting questions regarding foreign ownership of U.S. media, and is just one of the issues that should be studied regarding the proposed International Freephone service. Regarding 888, we are told there is an impending shortage of 800 numbers. I've asked some my associates in both telecom and marketing to respond to your most recent rebuttal in our thread. This, from the president of a reseller company, who discusses the real estate characteristics of 800 numbers. (I post for him as he's not online.) "Why should 800 telephone numbers not be traded in the open market? Portability opened the door. It is time to complete the ownership issue. There will be ample supply of 800 numbers if current holders can sell numbers. All will be served by the simplicity of one toll-free platform. All will be served by the elegance of the free market deciding who is the best user of an 800 telephone number." (My note: Existing market forces bear this out. Most high profile branded numbers were acquired from the private sector, not assigned by carriers.) If anyone's interested, just email me for a copy of a news article from 1994 where MCI brags about how it "acquired" 1 800 HARVEYS for Harveys Casino when it picked up the account. 1 800 THE MOST was acquired from the private sector. So was 1 800 COMPARE. Indeed, the big three carriers are some of the most active buyers of numbers, both for their own brand and media purposes, and as incentives for their customers. The problem is, as the original monopolistic real estate moguls, they are adamently opposed to private sector activity in this very open market that portability created.) The reseller goes on, "The situation we face currently with 800 telephone numbers is comparable to the homesteading of territory. In the early days of America's development, land was given freely to anyone who would care for it and develop it, whereafter, the land became their property. 800 numbers are no different. People develop 800 numbers by advertising and placing services behind those numbers. Property rights naturally instill themselves within the 800 numbers. As history has proven, homesteading of resources such as land or a telephone number, serves a valuable purpose. We have reached the time where more territory does not need to be freely distributed (ie, 888.) Instead, the existing 800 number ownership should be acknowledged." So, now there's media and real estate. Clearly, the single-disciplinary operational standard approach cannot possibly address the characteristics, nor the ramifications, of media and real estate market necessities. As other elements (trademark, etc.) are sent to me, I'll be glad to share them with the digest. J.

Big > deal. If you multiply that "month of revenue" by many thousands of times, it begins to add up in a big hurry. Oddly enough, some of those "slamees" stay with their slam-imposed carrier. > Why would they risk the repercussions of an unauthorized PIC change? Because there are none. There are no fines or other liabilities. And the carrier is entitled to the money for the calls you made. The worst that happens is that the customer is switched back to some other carrier. Remember, there are two sides to legislation: statute and enforcement. In the telecommunications industry, there is painfully little of the latter. > Of the hundreds of thousands of PIC changes that take place each month, > some of the customer service people will make a mistake. Uh huh. And considering that a slam to MCI is a keystroke away, that "mistake" is very frequently made. This is not rocket science; there is no reason, other than intent, for any customer's PIC to be changed. > I have not heard of this type of intentional action for many years. While I am not in the long distance business, I am personally acquainted with people who do run a long distance company. Slamming is a way of life. It is a standard exercise in the course of doing business. I advise everyone to make sure that LEC accounts are protected against carrier-instigated PIC changes. A side benefit of doing this is that you stop all of the telephone solicitation from long distance companies. Part of the mechanism of the hard-sell is to "switch" you on the spot. Notice you are never given an opportunity to think about it, nor are you given any hard information upon which to make an educated decision. If your account is locked against carrier tampering, the solicitor moves right along to the next victim; you don't even get a call. I had one line that constantly rang in the evening with MCI and others hawking "the big savings". No other lines in the house, and I have many, got those calls. Associates suggested that I confirm the phone's PIC-change status. Sure enough, it was the only one in the house that for some reason had not been protected against unauthorized PIC selection. With that situation corrected, the junk calls from telemarketers have come to a halt. John Higdon | P.O.

We'll start with that peice, then go on to some of the responses sent by individual readers, quite a few of whom wrote from the .nl domain. From: lester.hiraki@canrem.com (Lester Hiraki) Organization: CRS Online (Toronto, Ontario) In response to a request in Volume 15, Issue 118, Message 3 of 19, I am submitting the following article. The content of the article might contain some of the answers to the enquiries. > My uncle is 85 years old, and wants desperately to see a list of how > people in other countries answer the phone. The following swiped from Fido's Asian_Link and reposted here for general interest about general telephone usage and customs worldwide: World Telephone Cultures {Los Angeles Times} (Jul 26) CULTURE: Arabs greet each other with profuse politeness. The French want to know who's calling. Italians have love affairs with the machine. Alexander Graham Bell spoke through a wire to his colleague Thomas Watson in 1876. "Come here," he said, the first command uttered on a telephone. Oh, what Mr. Bell wrought. Around the world, different cultures have developed characteristic phone manners since Bell's day. No people open a call with more effusive hospitality than the Arabs. Whatever the subject of the conversation, it begins with what seems like five minutes of generally meaningless but absolutely essential greetings. A ringing phone is answered: "May your morning be good." "May your morning be full of light," the caller responds. "Praise God, your voice is welcome." "Welcome, welcome." "How are you?" "Praise God." "Praise God." "What news? Are you well? Your family well?" "Praise God. How are you?" "All is well. All is well. Welcome. Welcome." Only then might the reason for the call be mentioned. And the goodbys will take almost as long and are again excruciatingly polite. Compared to the Arab world, responses elsewhere are the soul of brevity: Britons and Americans generally say "Hello," although the latter sometimes simply say "Yes," and if they're in business or the military they may just answer with their surnames: "Smith." The French answer their phones with the familiar "Allo," and they often add their name and the phrase "Qui est a l"appareil?" that is, "Who is on the phone?" In a number of countries, calls are answered with a touch of suspicion or curiosity, a reluctance to talk until it's clear who the caller is. Italians answer "Pronto," or "Ready," and then it's the caller who demands "Chi parla?"--"Who's speaking?" -- assuming the right to know the identity of the person at the other end. Germans tend to answer the phone by barking their last names: "Schmidt" or "Mueller," even the women -- and even if they have titles, like Herr Doktor, which in other circumstances hey would insist upon. In Copenhagen, Danes will answer with both first and last names, even women: "Karen Andersen." In Spain, the response to a ringing telephone is: "Diga," or "Speak." "Diga" is also a common response in Mexico, but Mexicans usually answer "Bueno," meaning "Good" or "Well." Like the Italians, the Mexicans will demand: "Where am I calling?" And if they have the wrong number, they'll indignantly hang up, sometimes with a curse, as if it were the respondent's fault. Because of a cultural tendency to speak cautiously with strangers, callers must clearly identify themselves and state their purpose. Even then, the respondent may become vague and evasive. "Is this the Mexico State Justice Department?" a caller might ask. "I wouldn't know what to tell you," is the answer. Business people and government officials commonly refuse to speak to strangers on the phone even if it concerns simple inquiries like "Where can I buy one of your vacuum cleaners?" The train system won't divulge ticket fares or schedules on the phone; you must go to the station and ask in person. In Brazil, after slowly and patiently dialing a number, if you are lucky enough to get an answer, the respondent will say: "Who's talking?" not to be rude but to make sure the right number has been reached. Goodbys are elaborate, as if in person: "A hug" is a frequent sign-off, even to end formal business calls. "A kiss" is more casual, with someone you know personally. And the response in both cases is "Outro," "Another." Like American teen-agers, many cultures have love affairs with the phone, none more than the Italians. They talk endlessly with relatives, friends and schoolmates. The telephone call has replaced formal letters of invitation, congratulations and condolences. As almost everywhere else, the cellular phone, called a telefonino in Italy, has become a popular status symbol, used widely and indiscrimin- ately. Telefonini have recently been barred from parliamentary sessions, for instance. In Germany the telephone is hardly ubiquitous. You can get an unlisted number at no extra charge, and information operators will not indicate the fact to callers -- in effect denying your existence. One wrinkle that arrived under Germany's liberal immigration policy: the installation of illegal phone booths where foreigners can call home without paying long-distance tariffs. Officials of cellular-phone networks have countered the trend by blocking all calls going to Pakistan, Togo, Gambia and Vietnam. In Russia, like most things, phone use is affected by the growing gap between rich and poor, new and old, foreign and Russian. So mobile phones are big hits among the rich, but most Russians have no phones at all. Thus ads for apartment rentals specify "telephone" with the same pride as "garbage chute" or "closet." For those with phones, the answer to a ring is the French "Allo," which can be pronounced to reflect wide degrees of happiness or annoyance. Also popular are the curt "Da," or "Yes," and "Slushayu vas," or "I am listening to you." Because of the history of KGB taps, Russians are still careful of being overheard, often using the phrase, "It's not telephone conversation," to warn a caller to be discreet. Often in Moscow an alien conversation will break into yours, and sometimes, according to Muscovites, you can't help listening. These aural glimpses show a Russian life that is never the relaxed, gossipy "reach out and touch someone" conversations so typical in America. Instead they have some urgent goal -- such as arranging a meeting or a deal. "The reason for this urgency is the poor quality," says a Moscow resident. "Pay phones are unreliable and the caller wants to get his message across before the connection breaks down." In closed Arab societies, the telephone is a means of contact for those forbidden to see each other in person. A woman will call random numbers asking for "Mohammed," and when she finds a voice she likes, will strike up a conversation. In India, you wait up to seven years for a phone -- so when the connection is finally made it often prompts a neighborhood party. The euphoria ends about a month later when the first bill arrives and the subscribers realize how much it costs. In the Indian middle-class home, the telephone occupies the place of honor, often atop its special table, and is usually kept locked to prevent neighbors from making calls. But in the countryside where 70% of Indians live, phones are still a rarity: In some cases there is not a single phone in a village. In Southeast Asia, almost everyone uses a version of "Hello" to answer the phone. Hong Kong Chinese say, "Wei." In countries like Thailand, Vietnam and Indonesia, with a shortage of phone lines and a two-year waiting list, cellular phones are prized, but expensive -- running $500 to $1,000 in Singapore and twice that elsewhere. Bangkok's most popular radio program is a call-in show with phoners talking while stuck in the city's infamous traffic. Many posh restaurants have signs saying, "No Handphones," because people are fed up with the guy at the next table shouting into a phone. Some cinemas show trailers indicating that it is rude to talk on the phone during the movie. In Japan, the person answering will customarily say, "Moshi moshi," the equivalent of "Hello," or perhaps "Hai," that is, "Yes." If he or she has the right connection, the caller may say something like "Osewa ni natte imasu," or "I am indebted to you for your kindness." Sometimes people bow over a phone, although the other party cannot see the bow. Many older Japanese, who never saw phones until the era of the 1964 Tokyo Olympics, continue to use ceremonial phrases and bows over the telephone -- as if it weren't there. The standard goodby is "Ja, mata" -- "See you later" -- with the word "Sayonara" reserved only for occasions of a long or final parting. In many Third World countries it definitely helps to know an operator. The Indian writer Khushwant Singh remembers trying to place a call from New Delhi to Lahore in neighboring Pakistan -- when services were notoriously bad. After hours of trying, Singh was contacted by the international operator who suggested that she had relatives in Pakistan who had wanted to visit India but needed visas. Being a member of Parliament, she said, he might come up with the necessary stamps. Singh accepted the deal and within three minutes his connection was through. ---------------- From: 4sam3@qlink.queensu.ca (Scott Montague) En francais, nous disons "Allo?" when answering the phone. Scott From: Kimmo Ketolainen Most Finns answer to the phone with their name. Firstname, surname or full name. Some few people say "haloo" but I haven't heard that much. Some people, mostly older people, answer by saying the phone number. Kimmo. --------------- From: Alex@Worldaccess.NL (Alex) In Holland we pick up with either "Hallo" (means hello in Dutch).

Although, literally tanslated I say: "Good morning, with arthur" where "with" indicates the other end is "connected _with_ arthur" But it all depends on the level of politeness you include. In any case, one alwyas says one's name when picking up a phone. The most common one being: "With Arthur Meerwijk" Cheers, arthur ---------------- From: koos@kzdoos.xs4all.nl (Koos van den Hout) Of course there's the way American persons answer the phone : "Hello." (Sorry, couldn't resist. This may seem perfectly normal to an American but for someone who's used to other greetings it can be confusing.) In the Netherlands it's normal to greet with your own name. I say "Met Koos van den Hout" which does translate roughly to "This is Koos van den Hout" Companies mostly answer with a company name in the Netherlands: "Hogeschool Utrecht" ------------------ From: marya@oitunix.oit.umass.edu (Jeffrey William McKeough) Here's a few off the top of my head: Japan: moshi moshi Spain: digame Mexico: bueno Israel: shalom -------------------- From: Giray Pultar In Turkey/in Turkish, we typically answer the phone by saying 'alo'.

The Committee is charged by the Technology Policy Working Group (TPWG) of the federal Information Infrastructure Task Force with a year-long course of activities to develop a baseline understanding regarding what technologies are to be deployed when, where, and by whom. The project is being coordinated by the Computer Science and Telecommunications Board (CSTB) and is drawing upon inputs from multiple industries, sectors, organizations, and individual experts. A list of NII 2000 Steering Committee members is attached. All white papers will be made available to federal NII decision makers and be considered for discussion at a Spring Forum in Washington, D.C., May 23-24, 1995. White paper authors will have the opportunity to revise their papers after the Spring Forum. All papers- regardless of whether they are selected for discussion at the Spring Forum-will be presented to the government and will contribute to the Steering Committee's final NII 2000 report to TPWG and the public. RESPONDING TO THE CALL: In keeping with its charge, the NII 2000 Steering Committee seeks properly documented discussions with quantitative evidence/analysis on technical, financial, and economic aspects of technology deployment issues and prospects for the next five to seven years. Issues of particular interest to the Committee include: Architecture and facilities: Bandwidth capacity available to and from: government (all levels), corporations (domestic and international), small businesses and residences; also mobile users of portable platforms; Interoperability and openness: dimensions, barriers and facilitators; Interactivity and symmetry (i.e., relative support for two-way communication); Internetworking and interconnection regarding different kinds of networks and services; Public networks, private networks, virtual private networks. Enabling technologies (e.g., end-user devices, interfaces, and protocols); Recovery of carrier costs (facilities and/or services) in an open- network environment; Middleware technologies/capabilities: e.g., mechanisms such as digital signatures, encryption or search agents that protect intellectual property, privacy, security; directory services. Applications: Expected capabilities for digital libraries, distributed collaboration, software agents, smart cards, telecommuting, video delivery (on-demand & near on-demand), multimedia services; Expected attributes and implementation of electronic kiosks/public access facilities; Technology deployment issues affecting a particular domain (e.g., education, finance, manufacturing, transportation) which may have implications for other domains (e.g., establishing standards in health care); Critical hardware and/or software interface features, requirements, and standards; Equitable access and public service obligations (relative costs and implementation rates); Research and development: i.e., critical areas for future projects in device, software, and systems research; also private sector trends and priority areas for government-funded research; FORMAT REQUIREMENTS SUMMARY: Papers should begin with a brief problem statement and concentrate on analysis and forecast (five to seven year horizon) of deployment issues and key factors, including sources of uncertainty, contingencies, barriers and facilitators. Conclusions should concisely state the business case for a given deployment effort and any implications for public policy. Submissions should be double-spaced and should not exceed 6,250 words (approx. 25 pages). All papers must be signed by a principal and accompanied by a signed NRC copyright agreement. Statistics must be referenced; cites should be formatted as endnotes. Papers should be submitted in hard copy and electronic form (diskette or e-mail to jgodfrey@nas.edu) by April 27th.

Assistant ------------------------------ Date: Tue, 28 Feb 1995 16:24:50 +0500 From: sellers@on.bell.ca (Dave Sellers) Subject: Pizza Hunt Consolidated Phone Number - All Locations The following news release was issued by Bell Ontario Public Affairs to Ontario-based media on February 27, 1995. Bell rings up 310-1010 to reach 83 Pizza Hut locations TORONTO -- Eighty-three different pizza outlets from Cobourg to the Niagara Peninsula have identical phone numbers. A telecommunications nightmare, you say? A super telephone number, say Pizza Hut and Bell Canada. Throughout the 416 and 905 area codes, pizza-hungry customers can now dial the same seven-digit phone number, 310-1010, to reach any of Pizza Hut's restaurants, delivery and take-out stores. No need to look in the phone book; no area code required. Bell ServiceFinder (TM) service makes this new kind of seven-digit phone number possible. It provides a business with a series of call routing options that can be used alone or in combination to give customized routing capabilities. The service allows the business to advertise a single seven-digit local number and route incoming calls to pre-determined locations based on one or more options. "Whether you're at your home in St. Catharines, at a friend's place in Brampton or visiting your cousin's apartment in North York, you just dial 310-1010 to reach the local Pizza Hut for that area. The people who answer your call will take your order and make your pizza. It's that easy," says Doug Corbett, Pizza Hut's marketing manager. The ServiceFinder database will use the postal code associated with the calling number to identify which Pizza Hut location the call should go to. When the customer dials 310-1010, the system automatically routes the call to the nearest Pizza Hut. "No other food service company in Canada offers this level of convenience for its customers," says Corbett. "Our goal now is to make 310-1010 available across the country so no matter what city our customers are in, they dial the same number for a Pizza Hut pizza." Both the customer and the business benefit from the ServiceFinder service. "Besides making it easier for people to reach a business no matter where they happen to be, this service means the business can maintain a local look while getting greater value from its advertising," says John Strecker, national account director with Bell. In addition to the postal code option, call routing can be based on: - the telephone numbers of special customers; - the first three digits of the incoming call; - time of day; - day of the week; - a percentage of calls that each location should receive. Pizza Hut is the first Bell Canada customer to use the ServiceFinder service and is part of a technical trial. Bell Canada is awaiting approval from the Canadian Radio-television and Telecommunications Commission before expanding Pizza Hut's single number to other area codes and proceeding to market trials with other customers. That approval may come by the end of March. This is one of the first services to be offered on Bell's Advanced Intelligent Network (AIN) platform. AIN is a set of software features that work in conjunction with Bell's digital switches (DMS-100: digital multiplex system of switching) equipped with CCS7 (Common Channel Signaling #7) software. CCS7, which activates Bell SmartTouch (TM) services, passes information about the calling number between the DMS-100 switch and the AIN software. Pizza Hut's 310-1010 is also in use in Calgary, Alberta, and the company intends to expand the number to the rest of the country as soon as possible. Within the 416 and 905 area codes, all Pizza Hut locations are now using the 310 number except those in Oakville, Burlington and Milton which are expected to make the change this spring. The downtown Toronto core (south of Carlton/College, between Spadina Ave. and Bayview Ave.) is using 310-1010 and will have delivery service for the first time by mid-March. Pizza Hut, a subsidiary of PepsiCo, Inc., is the world's largest pizza distribution system with 478 restaurants and delivery units in Canada and more than 10,750 outlets in 88 other countries.

I make no warranties or claims; I will just tell you what they said. It cheap enough, you may want to order one or two. "Message recorder records anything without tape". This little thing fits in the palm of your hand and comes with a key chain attachment. Two buttons on the front, one marked 'rec' and the other marked 'play'. Whenever you want to remember something later on, just take this thing out of your pocket, press the record button and talk into it. It will hold ten seconds of whatever it hears, but the deluxe version will hold twenty seconds of talk. Later on when needed, you press the play button and the ten/twenty seconds of speech comes over the tiny little speaker attached. A new recording simply erases the old one. It looks to me like the sound quality won't be the greatest based on the tiny combination speaker/microphone used, but it should work for short memos. Inside this thing is a tiny little ciruit board with a chip that holds your speech. The person who showed me the one he got (and gave me the ad for reference) has done something quite interesting; something which may appeal to other Digest readers -- He opened the plastic case and took out the circuit board. Then he tossed out the plastic case, not needing it any longer. He mounted the litle circuit board in his telephone, and took the leads which had been going to the little speaker and connected them to his telephone handset instead. Two minature push button switches he mounted nicely on the side of his phone serves to cut the recorder in or out of the circuit, in record or play mode. He records his message by talking into the telephone. He uses it to give a standard answer phrase when he picks up a ringing line. Of course, you could do whatever you wanted with it. He mounted the little circuit board in a spare place inside the phone with a piece of double sided tape to hold it firm. It operates on four 1.5 volt button size batteries that come with it for free when you buy it. He thought about getting the six volts needed from the phone line itself, but said the extra bother of getting the voltage just right was not worth the hassle since the batteries last a long time (hundreds of plays). Anyway, I thought you might be interested in trying one of these. There is no kickback or commission to me, it just looked clever and I think I shall order one also. Item MR-10 the standard one is $9.95 plus 3.45 s/h = $13.40 Item MR-20 the deluxe one is $14.95 plus 3.45 s/h = $18.40 Two of the MR-20 deluxe units for $24.75 plus 3.65 s/h = $28.40 Three of the MR-20 deluxe units for $34.95 plus $4 s/h = $38.95 ($13 each) They offer a money back guarentee for thirty days after purchase, and say allow six weeks for reciept. They take checks or money orders payable to HOLST, Inc. or you can send them your Visa/MC/Amex number and expiration date with your signature. HOLST, Inc. Department DM-2265 334 W. Wackerly Street Post Office Box 1431 Midland, MI 48641-1431 No phone number was given. I can see where the twenty second version might have some interesting applications for short outgoing phone messages if you can figure out how to wire it in the phone line, which should not be too hard.

Given the number of people who recommended that I review it, I had expected a more up-to-date work. This *revised* (from "Dvorak's Guide to PC Telecommunications") version is dated 1990. Which means it's dated. Actually, even for *1990*, it's dated. The "acknowledgements" reads like a telephone book. A lot of people put a lot of info into the book. Unfortunately, a lot of them covered the same ground. Over and over. Again. From these original submissions, the book does not seem to be edited as much as concatenated. The material does not seem to have been organized into any kind of order, either. Modem installation starts in chapter two, but some of the information on COM ports waits for chapter twenty-three. The material is very uneven as to quality. Chapter twenty-four has an excellent section on what to look for in file transfer protocols. Unfortunately, it is in the second half of the chapter. The first half has already delivered the usual hackneyed opinions about specific protocols: errant ones, into the bargain. The linking and introductory material is sometimes painfully verbose, and pages go by without solid information. (The virus chapter? Ahem. Well, yes. I *do* have to say that, aside from the ridiculous definitions of "bombs" and "worms", and Richard Levin's promoting of his own program, it is not bad at all.) As usual, the preface promises to help you get started with a modem. It simply does not deliver. The reader will, by the time the book is finished, be familiar with terms and concepts, but not the practical details of how to get it to work. Well, some details, perhaps. Much time is spent describing how to put a "card" into the computer. But there is no advice on how to diagnose errors with speed, parity or word length (all fairly easy to recognize). The chapters on Macintosh, Amiga, UNIX and OS/2 are mere tokens. There is much more that is missing from this tome, as well. (The *only* mention of the Internet is as an email gateway between Compuserve and Usenet.) There are some individual goodies buried in here, but, to be honest, I can't think of any group to recommend it to, even considering some of the other poor works on the market. copyright Robert M.

(I understand that at least two more are in the works.) It is also the first to truly present the general concept of email security by covering the only other realistic option -- the Internet Privacy Enhanced Mail (PEM) standard and (Mark) Riordan's Internet Privacy Enhanced Mail (RIPEM) implementation. The book divides roughly into quarters discussing background, practical use, the PGP documentation, and the PEM RFCs. The work is considerably different, in style, to the Stallings (BKPRTPRV.RVW) and Garfinkel (BKPGPGAR.RVW) efforts. Those books, while not obtuse, were still written with a technical audience in mind. Schneier's work, while definitely showing the expertise he demonstrated in "Applied Encryptography" (BKAPCRYP.RVW), is clearly aimed at the general, non-technical reader. (Interestingly, while he *does* tell you where to find the RC4 algorithm posting, he *doesn't* mention the loophole recently pointed out in the Clipper "Skipjack" algorithm.) The straightforward style lulled me into thinking that chapter one was too long. It isn't: Schneier makes the important point that, for it to be *truly* effective, encryption must be used on *all* correspondence, even trivial items. So well crafted is his argument that it would be difficult to reduce the chapter by so much as a paragraph. Schneier uses this argument to good effect in pointing out some of the major deficiencies in the two systems. PGP is awkward to use, and PEM may use incompatible algorithms. Surprisingly, he does not emphasize (though he does mention) what is probably the major problem with each -- the inability to use the same system within and outside of the United States. The PGP fiasco is too involved to get into here (see the Garfinkel work for details) and there is not yet an "international" implementation of PEM (although there may soon be an "authentication only" version available). This won't help you design your own algorithm, but it is definitely for any user of email, manager of communications systems, or student of privacy and confidentiality. copyright Robert M.

Could someone please explain > what these terms mean? The following is a brief and by no means exhaustive explanation of D4 versus ESF. D4 was the original AT&T (Western Electric) product used by the Bell System for digital multiplexing of voice and data circuits at 1.544 Mb/s over copper transmission lines. When asked the way it was of you, the fiber company is now referring to the time slot (channel) framing format that you would like your T1 line to have. "D4" refers to the original specification which is also referred to as the Superframe Format based upon the way framing bits are used to define groups of the 24 channels multiplexed onto a T1 line. "ESF" refers to a newer framing format called Extended Superframe Format (hence, ESF). ESF provides improved false framing protection and network maintenance capabilities (performance monitoring.) In addition, ESF typically is associated with "clear channel capability" or, the ability for the user to take advantage of the full 64 kb/s data rate of any of the 24 channels on the T1 line. Typically the "D4" type of framing requires that there be a minimum number of logical "1's" being transmitted over the T1 line. This is necessary because various types of transmission gear along the T1 line (like repeaters) need sufficient transmitted energy to be able to extract timing from the signal. Hence, users were typically restricted from putting any data on a 64 kb/s channel that contained too many zeroes. In essence, the channel was not fully "clear" for the user. Alternative methods for maintaining a minimum 1's density were introduced about the time ESF was developed and included Bipolar with 8-Zero Substitution (B8ZS) and Zero Byte Time Slot Interchange (ZBTSI). Each of these permit the user of the data channel full freedom over the data stream that they send over it. That is, the channel is "clear" for the full 64 kb/s bandwith. B8ZS is the more common method and simply substitutes a special code whenever 8 consecutive zeros are encountered which is decoded at the other end. While associated often with ESF it does not require ESF to operate. The ZBTSI method requires the ESF format because it utilizes the 2 kb/s overhead data link inherent in the ESF format. However, ZBTSI is not often employed by many carriers today. I don't know if this will help you determine which type of framing format you want its at least a little backround on what they mean. ------------------------------ From: levine@seas.smu.edu (Dr. R. Levine) Subject: Re: What is ESF and D4? Date: 28 Feb 1995 20:50:47 GMT Organization: SMU - School of Engineering and Applied Science Extended SuperFrame (ESF) uses a different sequence of binary bits in the framing bit position of the T-1 bit stream. The repetition of the framing bit pattern occurs after 24 frames rather than 12 in "plain vanilla" D4 T-1 framing. Some of the framing bit values in ESF are not fixed and can be used for operations, administration and maintenance (OA&M) messages, and others are always used for an error detecting code (CRC6 code). ESF is also a requirement to install ZBTSI clear channel line coding, but this is only used by USWest and PacTel, not by the other local/regional telcos. To determine if you want/need ESF, first examine the extra cost of the hardware/software in your terminal equipment (your channel bank or PBX). Then examine the extra cost (if any) for the service from the carrier. What you get (primarily) with ESF that you don't get with D4 is the ability to automatically and continuously monitor the T-1 link for bit errors while all the 24 voice channels are in full-time service. With D4, if you suspect problems, you need to arrange to take one or more channels out of service and perform a manual test involving co-ordination with the telco in most cases. Try to make a cost comparison mainly between the presence vs. absence of the automatic test capability. A good customer equipment software system should warn you of even small bit error rates which may predict more serious problems and allow preventive maintenance. What is this worth? Does it justify the extra initial and/or monthly cost for ESF vs. D4 service? ------------------------------ From: levine@seas.smu.edu (Dr. R.

GSM is a cellular system using digitally coded speech. GSM is in use in about 7 European countries and will eventually operate in over 14, thus making roaming theoretically feasible technically (but in practical terms dependent on the existance of business agreements between your home GSM system and the GSM system operating company which you visit). GSM is difficult or probably impossible to "clone" because it uses a challenge-response algorithm for authentication and identification of the mobile unit which does not produce an invariable (and therefore cloneable) identification signal, as most analog cellular systems do. It has nothing fundamentally to do with the digital vs. analog issue, but is merely the result of a better authentication transaction design. ------------------------------ From: shirleyg@stanilite.com.au Subject: Re: E(TACS) and GSM Date: 28 Feb 1995 03:54:34 +1100 Organization: Stanilite Electronics Pty.

ETACS is Extended Total Access Communication System or something similar. TACS is the UK version of the U.S. analog cellular standard AMPS. Major differences are in the frequency range (only slightly different) with some minor ones in data on control channels etc. The extended bit is because the TACS standard has a section for extended frequencies with a lot more than the 1000 or so in AMPS. GSM is a French standard which is (roughly) translated as Group Special Mobile or something similar. Someone else will know exactly. GSM is digital whereas TACS is analog. This means your calls are more secure but the coverage will possibly be not as extensive as it is a newer technology (thats the way with GSM and AMPS in Australia anyway). > are around five cellular phone service providers in our country, and > most of them use E(TACS).

If your GSM service provider is international or has agreements overseas the international roaming is possible with GSM. Vodaphone (who are one of the three GSM providers in Australia) has networks in other countries where you can roam. Telecom (another provider) has agreements with other providers oversea. As TACS is mainly used in UK and China and a few others then it is no where near as suitable for international roaming. > Also, this service provider that uses GSM says that they're the only > provider that's 100% digital.

I couldn't say for sure with this but TACS (and AMPS) were never designed with much security in mind anyway and as the GSM standard has the benefit of hindsight when it comes to these security issues it would have to be safer from cloning. AMPS and TACS phones are fairly easy to clone if you know what you are doing (and can read the IMSI and ESN over the air anyway). > Also, they say that analog systems are very prone to charge errors. > Is this also true? Or are they just trying to scare me from going to > the other service providers? I wouldn't know about this but if the equipment is any of the big names such as Ericsson or Motorola or a smaller type of equipment that has been extensively trialled in a country like Australia like the company I work for has then the basestation shouldn't make these type of errors. The main problem would come from the providers of these bases with inferior land lines (false answers) and not having answer type signals (line reversals or whatever) on the lines and just guessing when the answer has occurred ie. after ten seconds. In short go for the GSM phone and provider: - if the GSM coverage is good (ask the providors) or at least bearable, - if the GSM phone is not excessively expensive (shop around), - if the TACS systems will be non-existent in a few years like in Australia (although in 5 years the phone will have had a pretty good life anyway). - if cloning (and you have to pay for the stolen air time) is rampant where you are. - if international roaming is important (as long as the provider is international or can guarantee agreements with providers in other countries. - if you care if other people hear your conversation as anyone with a decent scanner (and some intelligence or maybe even without) can listen to your TACS or AMPS phone conversations. For the average person this is just about impossible with GSM. I have to repeat though the coverage for the analog system is nearly always more extensive than the digital systems in most countries simply because it has been around longer. This is changing though. Check it out thoroughly first though. Hope that helps. BTW where is the .jp domain - the phone number is in the Phillipines isn't it?

Actually, V.35 didn't evolve, you were reading an obsolete standard. The last time V.35 appeared as a published standard was the CCITT 1984 Red Book. If you were to read the V Series for the CCITT 1988 Blue Book, you would find that the only mention of V.35 was to point out that it is out of date, and V.36 & V.37 are now recommended. This is the best kept secret in data communications, and a pet peeve of mine. V.36/V.37 is designed for the high speeds that modern data equipment runs at, especially devices like routers, which will run at T1 or E1 or higher on their high speed serial (HSS) port. I have seen applications that ran error free as high as 8 Mbps on an HSS port. The problem with V.35 was that its balanced transmiter voltages were too low (0.55vdc) so it was susceptible to electrical noise from florescent lamp ballasts, a worker using an electric drill in another room, etc. That is the only real electrical difference for V.36 -- its balanced transmiter voltage is ten times as much, (6vdc) and therefore much less susceptible to interference. This is important now that data services such as frame relay are becoming popular, as frame relay is specifically designed to work on an error-free channel. The other "change" that was supposed to happen in V.36 was to replace the old, bulky, fragile V.35 connector that was popular in Europe. Unfortunately, the V.36 standard doesn't call out when that is supposed to happen, it simply says "after an interim period." In addition, the connector that V.36 recommends for future use is the old RS-449 connector, a DB-42. While this is an improvement, it is still too bulky for modern data devices. What has actually happened is that the DB-25 connector is almost universally present on the backs of DSUs, routers, etc., and custom cables provide either the old V.35 connector, or the RS-449 connector. There is another standard, EIA 530, which uses the DB-25 connector, and is electrically compatible with V.36, but it never took off. So, the majority of high speed serial ports today use a DB-25, with a custom cable to go to a V.35 connector, and this is typically duplicated on the other side of the data connection! Also, only about three-quarters of the high speed serial devices that come through our lab are at the 6vdc driver level -- about a quarter of them are STILL using the obsolete, less-desirable, V.35 electrical level, seven years after the standar changed! This isn't a real problem, as V.36 was designed to be backward-compatible with V.35. The V.35 device is designed to withstand voltages higher than 6vdc on its receivers, so it won't be damaged by a V.36 transmitter. Don't forget, though, a V.35 voltage level means that the data device is more susceptible to electrical noise, and therefore more likely to take errors. By the way, V.36 doesn't stand alone. It calls on V.10 for the unbalanced electrial driver/terminator requirements, and V.11 for the balanced requirements. It also refers (as did V.35) to ISO standards to describe the connectors' physical characteristics. (ISO 2593 is the "old" V.35 connector.)

I read this treatise on loop current with astonishment, until I reached the end, where I saw a plug for a loop current attenuator. Let's discuss a few basic facts: a) EIA/TIA 470-A "Telephone Instruments With Loop Signaling" is the "bible" on how to design Customer Premise Equipment (CPE) for North American POTS lines. It has tests that require the CPE be subjected to and operate with loop currents from 20 to 100 ma, such as Figure 4-11, DTMF Signal Level Characteristics. b) The telco has no obligation to provide a minimum of 23ma, and I'd love to see the transcript of someone calling GTE customer service and informing them that GTE had to up their loop current from their 20ma minimum to 23ma. c) The real-life currents a CPE will see are governed by local loop design and the CO battery and feed coils, plus the resistance of the CPE itself. d) The most common reason that modems don't work well over carrier systems is that many of them don't provide the 300-3400 Hz bandwidth that the newer, high speed modems need. Lets consider the worst case loop current example likely in North America. A local CO theoretically may put out up to 56.5vdc during fast battery charge, and the CO applies battery to the subscriber line with 200 ohm/ 200 ohm battery feed coils. If the CPE is just outside the CO, there will be no loop length to speak of. If the CPE is unusual, it may have as little as 100 ohms off-hook dc resistance. So, 56.5vdc/(400 ohms feed coils + 100 ohms CPE resistance) = 110ma, which is where I assume that Mike got his high specification from. A more realistic calculation is 52vdc/(400 ohms battery feed + 600 ohms loop resistance + 200 ohms CPE resistance) = 43ma. (Most digital COs I'm familiar with have a dc voltage of 52, not 48.) The only way we will see his 27ma loop current is with the maximum permitted loop resistance (1200 ohms) plus the maximum permitted CPE resistance of 300 ohms. 52vdc/(400 ohms feed coils + 1200 ohms loop + 300 ohms CPE) = 27ma. (The actual loop resistance can exceed 1200 ohms, but at that point, the telco will start using load coils and/or loop extenders and/or other special service modules, all of which can degrade modem communications.) Old carrier systems, such as the GTE 84A, will interfere with any modem much faster than 1200bps. The 84A puts two customers on one copper pair, and the unlucky customer on the "subscriber" pair (the non-copper link) can expect to see an on-hook voltage of only 6vdc (provided by NiCad batteries) and 30vrms ac ringing which is square-wave, not sine-wave. GTE 82A carrier puts six customers on one copper pair, and uses 300vdc on the copper pair to power the field equipment, which is in aluminum cans put on the service poles. (I've received some healthy shocks from the 82A systems!) Modern carrier systems are also a threat to modems, such as the AT&T SLC96. (pronounced slick 96) If the telco is trying to maximize the number of customers serviced, the SLC96 has a feature called "channel compression" which halves the available digital bandwidth allocated for a single subscriber's line. This lowers the voice quality only slightly, but it plays havoc with modems, even 1200bps speeds. Received carrier signal levels are also important to modems. Local loop design guidelines call for a maximum local loop loss of 8.5dB, although 9dB isn't too unlikely. A digital CO has 0dB through-loss, and an older, analog CO, such as a GTE #1 or #2 EAX will have a through-loss of 0.8dB. Then, don't forget, we have a loop on the other side of the CO going to the called modem, so our maximum dB loss on a local call using a pair of loosely-engineered loops through an analog CO is (9+0.8+9) = 18.8dB. (These numbers come in part from EIA/TIA-464-A, which describes the North American Loss Plan for analog and digital PBXs.) Now, dial-up modems typically transmit at -11dBm. (-9dBm is the maximum permitted by FCC Part 68 & ISC CS-03 requlations). -11dBm through a facility loss of 18.8dB gives us a received signal level at the far modem of -29.8dBm. Any modern modem worth its salt can connect down to receive levels as low as -36 to -38dBm. So, the local loop design rules shouldn't interfere with modems. Why, then, do people have trouble connecting with modems? Besides carrier systems, or long lines with load coils, there are impairments on the local loop. These include phase hits, gain hits, dropouts, echo, envelope delay, noise, and impulse noise. The telcos are also notorious for leaving "bridge-taps" on the lines. Even supposedly "conditioned" lines such as a C1! The bridge-tap problem in North America is well-enough known that the ISDN BRI 2B1Q line coding was chosen because it is particularly resistant to bridge-taps. Finally, there is a situation where Mike's advice to lower the loop current on the line can help. I have come across really cheap modems where higher loop currents (45ma and up) can "saturate" the windings of the low-cost isolation transformers they use in their front ends. This has the effect of drastically attenuating the ac signal levels passed through the transformer, and preventing the modem from connecting to the far end. However, no "brand-name" modem is going to be susceptible to this problem. And, if 40ma of loop current "burns-out" a piece of CPE, it cannot have met the FCC Part 68/ISC CS-03 requirements. The required loop simulator for testing can deliver in excess of 100ma, and when we test CPE for registration, we test at 20ma and 100ma.

Special thanks to Pat, TELECOM Digest Editor for his note on my post. I called back my local carrier to follow his suggestion (multiple 1-800 numbers and local lines, with hunt groups for the 1-800 numbers), and was told that Caller ID on equivalency lines was no problem (although the Caller ID on the second line is not guaranteed to be 100% reliable). It turns out that the person I talked to first when placing my order was new (although she pretended to be very experienced, telling me that she was the only one in the office that could handle 1-800 numbers, which also turned out not to be true). She put me on hold when taking my order, and claimed she was talking to a technician about the issue of Caller ID for equivalency lines and told me that the technician had also said that Caller ID was not techically possible (she wouldn't allow me to directly talk to the technician). She also told me that there was no one else in the office that I could talk to about the issue, and she was absolutely certain it was unavailable. End result is that thanks to Pat and a more experienced individual in the local carrier's office, I will shortly have Caller ID on my two lines. Thanks again, Paul Chehowski paulc@hookup.net Sulis Computing ad771@freenet.carleton.ca [TELECOM Digest Editor's Note: Actually, it is just as reliable on the second, overflow line as it is on the first line, which is to say it comes through accurately over 99 percent of the time. Bear in mind you *do* have to have to display boxes (unless you use the trick I described) and you do need to pay for Caller ID on both lines. I've found most of the enhanced custom calling features will work perfectly fine where roll over or hunt lines are concerned. That's because these features are tested for *before* it gets to the point the CO has to look for a second line. In other words a call comes in to your enhanced line (meaning you have things like call screening, automatic callback, etc.) to the main number. The CO says 'okay, he can have the ID of the Caller. He wants us to screen for certain callers and deny them access. He wants to be able to call them back automatically if desired.' All these things get done, or evaluated, *then* the call is presented to your main line and another piece of equipment says oops, that line is busy, we have to give the calls to line two. If the call is supposed to be screened out, it does not matter if in fact he would be shunted to line two. The decision to screen is made on what the caller dialed and what he anticipated would happen. Now if the caller actually dials your line two and you don't have screening on that line as well, then he *will* get through. If you have screening on that line also but his call gets hunted on to line sixteen or whatever, then he will get blocked. With all the features, you have to have them on the number the caller *dials*, not the number he actually winds up getting in on (or would have gotten through on if he were not screened, etc). Therefore if you want a relatively decent level of security and control over your phone lines, you keep all your roll over numbers secret (preferably out of sequence and all over the exchange so that guessing at them becomes difficult) and you load up your main listed number with all the enhanced features designed to give control of the phone to the call recipient, like Caller ID, blocking, return last call, etc. And contrary to what the rep said, Caller ID is reliable, even if it takes an extra second while the switch hunts through your group of lines and has to search all the way to line 38 or whatever. Caller ID is not passed until it gets a clear path and the subscriber's phone has run one time.

[TELECOM Digest Editor's Note: I stand corrected. It was five miles per point; one hundred points minimum. I think I made that error unconciously on purpose, that way I knew there would be an oppotunity to repeat the message later. In True Rewards, AT&T is giving a point for each dollar of long distance calls you make over $25 per month. If your bill goes over $75 then you get two points for each dollar spent. If you move, notify AT&T of your new address and phone number; you get 100 bonus points. If someone signs up for AT&T residence long distance service and gives you as the referral, you get 300 bonus points. Points can be redeemed at any time when you have at least 100. They can be redeemed for various things, but the one that interested me most was: $5 credit toward your AT&T bill for every 100 points. (You get those 'pay to the order of the telephone company' credit slips to redeem with your phone bill.) One thing AT&T stressed was that 'point pooling' is allowed, and encouraged. All you have to do is tell them you want to transfer your True Rewards points to someone else; they'll be happy to do it. They said having two or three people sign up for AT&T residential service (300 points each) along with transfer of points from people who have collected them but are not interested in redeeming them could 'result in someone having hundreds, or even thousands of points in a very short time ...' The thing which appeals to me is the credit on my local telco bill and here is how YOU can help: If you have been meaning to possibly send a donation to the Digest but have not gotten around to it yet -- or maybe you just don't have the money to spare -- then you can use this round-about way of helping instead. If you intend at some point in the near future to sign up for AT&T residential service, do it through this special phone number: Call 1-800-383-6158. The representative will switch you to AT&T for free and enroll you in True Rewards. Give the representative REFERRAL NUMBER : BY-6195039315666. Tell the representative to apply the 300 bonus points to that account. Everytime someone switches to AT&T in this way, I get the points. Got more than one line at your place? Feel like giving one of them to AT&T? If you are not interested in participating in True Rewards but got a statement recently from AT&T with your point balance shown you can also help. Mine arrived by bulk mail today so I assume there are lots of these in the mail now. Do this: Call 1-800-869-9900. Tell the representative your True Rewards account number which is printed on the bottom of the statement they sent you. Tell the representative to transfer all of your points to my telephone number 708-329-0570. As the points come in from new subscribers to AT&T who use my referral number and as points come in from transfers out of accounts where they are not wanted, I'll redeem them for credit on my always high, frequently delinquent phone bill. (I haven't gotten cut off once yet this year, I'll have you know! Not only that, since I got my last 'deferred payment plan' agreement finished a few months ago I am eligible to stall by starting another one if absolutely necessary.) If you do sign up using my referral number or transfer your unwanted True Rewards points, please send me email and let me know so I have an idea what's going on. You have to call the two numbers shown above to do all this; the regular representatives on the published numbers they use can't handle it. Thank you very much!

There is a trick to have the phone discharge itself without using any "peripherals". Just go into the "menu" and scroll until you see a message that is fairly long so that the maximum number of LED lights are on. I believe "Silent Keypad" is a long message. The phone will automatically "bank" in this mode without going into standby. This will drain the battery quite well until it starts beeping low battery and turns off. You may then have to repeat the process. As to a previous message about re-programming the low battery voltage ... there is no USER-modifiable way of changing this. Whatever article you saw must have been talking about an old Motorola phone. When I say old it must be several years old and has since been discontinued.

Doing this is a good way for the first cell to hit zero to be pushed negative as the other cells continue to discharge. This is about the worst thing you can do to the cell, and will ensure its shorter life. The phone knows how low to take the battery. Trust it. If you don't want to do that, use the intellicharger and don't leave it on trickle. Not overcharging the battery will be the best move towards keeping the battery away from voltage depression, and get good service.

Not I! The carriers *are* active numbers marketers. They buy them all the time, and receive revenue by such acts as MCI's "acquiring" 1 800 HARVEYS for Harveys Casino. This helps get them the account, and then delivers higher volume call completion (revenue), because the *media* element of the phone number is powerful stuff. However, they want license to buy and sell, but let no one else in the marketplace. That's simply not fair.

Don't flatter me, I didn't create it, I'm just a fascinated and enthusiastic observer of a marketplace creating itself. But, as a marketer, I take issue with your "assets are thin air" suggestion. A brand is an asset. It is only valuable because of the desire of the consumer, and the perception of the stock holder. The price of coke, and its stock value, has a hell of a lot more to do with the cost of advertising awareness, and maintaining desire, than the cost of the water, syrup and bottle. > Do you also claim copyright on license plates with FLOWERS or "TCBY > 1" and thus preclude the un-licensed use of them?

The problem is, how can you do this in a reliable way? It's not easy to fake Caller-ID, especially if the phone company and/or your CNID box is smart (i.e., won't fall for fake tones sent after the true ones). This is because the CNID information is generated by the phone company; most people don't have the skill or opportunity to convince the switch that the line they're using doesn't REALLY have the phone number it thinks it does ... On the other hand, how difficult is it to convince IRC you're not who it thinks you are? If you're a UNIX user, setenv IRCNAME telecom@eecs.nwu.edu and Bingo! Pat gets some irate email. (Or at least I think he does, 'cause I can't find a header with his address to verify it. It's late. :) Some UNIX systems run a program called "identd," which will supposedly verify such information, which is perhaps even closer to Caller ID. But identd is just another program; there's a version of identd out there that will spew forth whatever identity you desire, if you're unscrupulous to install it on your machine. The technical knowledge required to install such a program is, in my opinion, several orders of magnitude smaller than that required to hack the phone system. If you're running IRC from a personal computer, it's even more trivial. Most such programs offer a setting where you can supply whatever you want as your "real name." The same goes for electronic mail programs. It's as if it were relatively easy for people to purchase their own exchanges that could generate Caller ID and send it forth -- you could send any number you wanted and it'd be difficult for the called party to figure it out. Lest anyone get the wrong idea, I'm wholly against any form of net censorship; free speech is too important. The risk here is that promoting an "Internet Caller ID" as a safety feature that reliably identifies the calling party is far too premature. Perhaps when PGP or something similar becomes widespread and as easy to use as plugging in a Caller ID box ...

I won't push that, its just how I think. When I was younger -- growing up in Chicago, as a matter of fact -- I was sure I would never grow up in a way that would be known as being "old-fashioned". When I was 13 and buying Elvis records, and in my 20's protesting the Vietnam war, I just couldn't understand the "old- fashioneds", who "just didn't get it". Then I realized, as I was reading and agreeing with the paragraph above, how old-fashioned I must seem to be when I insist that life was better with well-enforced unwritten rules about public discourse and activity. [TELECOM Digest Editor's Note: The problems started in the USA when we decided to get rid of religion. Now I quite agree that religion has a lot of excesses which are not good, and further that no one religion is going to suit everyone. A good many people were quite annoyed by some of the excesses of the primary religion in the United States. I do not think the people who worked hard to accomplish separation of church and state over the past two decades or so are orges or devils. I think they were well meaning people who wanted to see the Constitution of the United States enforced better than it had been. The trouble is, constitution or no constitution, religion is what was holding together the social fabric in this country. Yes, there were lots of things wrong when religion was the dominant thing here, but I am not sure those things were 'more wrong' than the things we see wrong today. And anyway, must it be one end of the spectrum or the other? I beleive the folks who worked hard to get religion out of the schools and government offices assumed that even without religion present, people would continue to behave in a moral and ethical way. The trouble is, a great many did not. Religion was a powerful sword hanging over their head and for all its excesses and bad points, my gosh did it promote for the most part a sense of civility among us. When religion was abolished, nothing took its place, and that is the problem. Now we just have a void. I don't care if it was your religion or my religion or whosever's religion, *any* religion provided a bit more to grasp on to, a bit more to live for, and a sense of right and wrong than the void we live in today. I never could understand what people have against religion anyway. After all, it is whatever you want it to be. I think they mistakenly say 'religion = excesses of the Christian Right Wing', and that is wrong. They should have started their own religion instead, rather than getting it tossed out of our public institutions entirely. There need to be those goals and standards we set for ourselves, and religion forces us to make those settings; to recognize those goals and standards. Of course telling people to start their own religion is unrealistic. Very few people can (or choose to) use their brains that well, or accept the discipline in their lives that would result.

Phil Karn is the father of the KA9Q TCP/IP implementation, used for packet radio and various DOS applications. Jun Murai is founder of the Japanese WIDE Internet. The Karn interview talks a bit about KA9Q and mobile IP, but concentrates on encryption and privacy. Along the way, there is discussion of Clipper key escrow, PGP and the hybrid methods of data cryptography -- most, however related to mobile IP. Jun Murai starts by describing the situation at Keio University where all students have access to the network via a wired campus and wireless connections to laptops.

What is the common practice today when someone applies for cellular service? Credit check via one of the consumer credit agencies or via D&B if a business is the applicant? Is an additional credit check done if someone adds on a cellular modem? Is anyone using the practice of approving to a certain dollar limit and then cutting off service for the rest of the billing period if the limit is reached? How might today's practices be affected when cellular data (CDPD) is in more widespread use and the typical monthly bill is higher than today's? (You might say that it won't matter because CDPD won't be more widespread until the price is lower. Then it might not matter.) Any help is appreciated. [TELECOM Digest Editor's Note: A credit check is done, and a deposit equal to what the carrier estimates will be the charges for one or two months is required if the subscriber's credit rating is not up to the standards the carrier wants. I don't think it matters if you use a modem or not.

Do I have to read seven to ten copies of this in every newsgroup, even areas as obscure as alt.games.whitewolf? All this, on top of the maybe twenty or thirty copies I've gotten as e-mail? Can there possibly be anyone on the planet with an e-mail address who =doesn't= know about S.314? Now, that being said, I finally read one of the marked up copies of the current law, showing the changes that S.314 would make. And having read them, I am convinced that every single analysis I have read is either mistaken, exaggerated, or an outright lie. It's right there in the text. The section that everybody is scared of, the one that makes telecommunications vendors responsible for any obscenity or threats that swim in their bitstreams, is prefaced with "Whosoever KNOWINGLY ...." (Emphasis added.) That's right. They left in the word "knowingly." Which means that if somebody uses your BBS, or your email service, or your anonymous remailer to send someone an invitation to be the star in a pornographic snuff film, and you don't know about it, you're not in violation of the Exon bill. The easily alarmed might worry that some court will say that you =could= have known, and therefore =should= have known. But that's not up to prosecutors, that's up to juries. When witnesses testify as to how many kilobytes or megabytes flow through your system per night, no jury is going to say that you should have read it all. If you present evidence that you couldn't have known, because those bits were all encrypted and people didn't tell you what was in them, nobody's going to rule that you =could= have known, let alone =should= have. So. What do the people who oppose S.314 =and who understand it= REALLY want? The only reason I see to oppose S.314 is if you =want= BBS sysops and telephone sex vendors to be immune to obscenity and harrassment laws. If you want it to be legal for people to use email, or web pages, or improvised FidoNets or whatever to send around JPGs of perverts raping 6 year olds, or detailed descriptions of rape/murder/torture fantasies with people's real names for the victims, or GIFs of people having sex involving excrement, carving knives, and/or animals ... well, then say so! Because if that's what you want, then I agree with you 100%. As the late great Justice Hugo Black said, "I am a plain and simple man. I believe that when the Constitution says, 'no laws,' it MEANS 'no laws.'" Of course, there's no way that the American people will permit this. However, that's not, in my opinion, a moral reason to lie about the contents of a proposed law, and stir up a net.lynch.mob. J. Brad Hicks Internet: mc!Brad_Hicks@mhs.attmail.com X.400: c=US admd=ATTMail prmd=MasterCard sn=Hicks gn=Brad [TELECOM Digest Editor's Note: When I ran the pieces on S.314 a week or more ago, I also had some second thoughts about whether or not I really wanted (a) to run it -- because it had appeared so many other places; and (b) because I was not really sure if I agreed with the claims of the petition's circulators. Now I don't make my own agreement or disagreement with something be the reason for publishing an item or not, so that pretty well answered (b). But as you point out, it had been appearing lots of places. The existence of the 'net.lynch.mob' in and of itself was worth commenting on. The 'knew or should have known' is going to be the key to the whole thing if S.314 passes. What that means of course is that AT&T, Sprint, MCI, Compuserve, AOL and the others with big name attornies who know how to properly suck up will be left alone while Joe Blow's BBS will be hounded and put out of business, because he cannot afford to fight the government and wouldn't know how to begin fighting anyway. It won't *really* have anything to do with what you knew, did not know or should have known. It will have everything to do with your status and where you are relative to your position near the bottom or top of the barrel we all spend all our lives trying to crawl out of. I suppose that if you run an anonymous remail service one could make the claim that, 'well, you really should have had a good idea what your client base was using you for ...' Likewise I imagine if you operate a site which seems to have an awful lot of 'incidents' in which users get their knuckles rapped from time to time over the content of their messages one could make the claim also that your traffic is not that great that the smut could repeatedly get past you undetected, in which case you 'knew or should have known', etc. And as you point out, the decision on who knew or should have known what is a decision made by a judge or jury, not a prosecutor. But that is all a very moot point: who has the *time and resources* to fight, whether you win or lose? I quite agree with you that the people putting out the anti-S.314 material might have shown a wee bit more intellectual honesty about what I suspect was the real intentions of many: as you pointed out, to make the hard core smut peddlers completely prosecution- and judgment- proof. Tom Lehrer, the Harvard mathemetician and comedian commented in one of his routines that people who like smut never actually come out and say so. They always couch their objections to laws against it in terms of the First Amendment. They prefer to speak theoretically about (perhaps) far-fetched conclusions which will result. How refreshing it would be to have someone simply say, "I love pictures of little boys doing the no-no thing, and I don't want laws forbidding me to possess or share the pictures with others." Now that would be a change, to forget the First Amendement b.s. and say where you are actually coming from. But as you point out, the public would never allow that; on the other hand, there are still sufficient numbers of people who (like myself) will support the First Amendment, at least when it suits them, so these discussions always wind up going in that direction. And thank you for your honesty, I might add.

I know this has been covered before, and it's even alluded to in the rest of the original message, but I think that it is important enough to be stated very seperatly: **** There is (almost, see below) NO RELATION between the framing on a T1 and the ability to transmit clear channel data ***** When specifing a T1 Facility, there are two seperate, INDEPENDENT parameters that are in volved. The first is the LINE CODE, which specifies how the bits are encoded onto the copper line. This can be either AMI, or B8ZS. If the line code is AMI, then there is a requirement that there be at least 12.5% Ones in the data, and there be no more than 15 consecutive Zeros. Although you can run individual 64k channels on an AMI T1 (if the adjacent channels are unused) it is typically only used for voice and Nx56k data. If the line code is B8ZS, then there is no "Ones Density" requirement, and "clear channel" Data can be passed. Some equipment also supports a "line code" refered to as "BIT-7". This scheme uses AMI, but sets bit 7 to a one if an all zero byte comes through on any channel. (This is not reversed at the other end of the link, so this scheme is very unfriendly to most data). The second parameter is FRAMING. This can be either D4 (Also refered to as SF) or ESF. In some cases, an UNFRAMED T1 may also be specified. The framing is what is what allows the T1 to be broken down into 24 64k channels (DS0's), but has no bearing on what data can be put into the channels. As mentioned in another article in the same issue of the Digest, ESF provides many benefits over D4, and should probably be selected if your equipment supports it. The one time there is a relation between frmaing and line code/ones density is in the case of ZBTSI. This coding scheme operates on an AMI/ESF line (using some of the spare bits of the ESF framing) to allow for clear-channel transmissions on an AMI facility. This scheme is used when older transmission systems are in place (which will only support AMI) to provide clear channel capabilities. I hope this clarifies the (non) relation between framing and clear channel capabilities.

Let me first give an overview of the project we are working on. Overview: Lunar Rover Initiative In 1998, Carnegie Mellon University intends to land a pair of rovers on the Moon. The mission objectives are three-fold: 1) To demonstrate that educational institutions, with private corporate backing, can conduct useful space missions beyond Earth orbit; 2) To demonstrate that teleoperated rovers can work on the Moon for long periods of time (up to two years); 3) To return from the Moon a rich live video feed which can be used by the private sector, by lunar researchers, and by educational interests. A rich video feed is essential for this mission, since most of the science objectives are observatory in nature. =================== We need to transmit about 6 Mbit/sec continuously while the robots are travelling on moon. This makes mechanical pointing of the antenna (located on the robot) difficult and hence we are looking for electronic beam steering (and hence phased arrays). Any information about phased array systems (companies/contact names, phone number, existing systems for satellite applications, pointers to recent developments in technology, papers, conferences etc.) would be much appreciated.

I am going to be recording her in a digital studio for a voice mail project in about one month and doing all the basic prompts required for a voice mail system as well as all basic intercept announcements. My thought is, since there are SO MANY bad prompt sets out there, to do a decent, clean prompt set that covers voice mail, basic IVR applications, Bank-by-phone, Credit Card Debiting, intercepts, CLASS,and coin announcements. All numbers, dates, etc -- recorded in a STUDIO, digitally -- not with a handset microphone in a noisy equipment room. All edited cleanly and available on a CD-ROM in digital format. I am a sound editor in Hollywood and do a lot of video games so I have access to a CD Writer and digital editing equipment. This will be done correctly. However, I would like some input. If any of you have done a voice mail or IVR prompt set, send me the script. I'd like to cover as many prompts as I can. I would also like to come up with a standard file name format for a standard set of prompts so we don't have the mishmash of filenames that currently exist. If you know of an existing "standard" file name format please let me know. I know that in C.O.'s there are huge drum tape machines that play the intercept announcements. What do you C.O. guys use to get recordings onto these things? For IVR guys, what digital file format do you use? I would probably put the files on the CD in 44khz 16bit Mono .aiff and include a utilty to convert to .wav, and Dialogic formats in whatever sampling rate you wish.What other formats should be included? Should the CD be playable as a CD? What do you want? I will also include all Telco progress tones, DTMF signals, MF signals,all foreign ring signals. All clean, all perfect. I think this would be a valuable tool for anyone in the IVR industry or anyone wanting to play around. I'm doing this because I occasionaly build IVR systems and would really like to have a set like this. I have the equipment and know the best voice in the country. Also, I think it will be fun. The CD would be sold for a reasonable flat flee with no additional license fee required. I will, of course, send one to anyone who helps out. So ... dig around. Find those scripts! THINK about it. This thing will save you countless hours of frustration if it's done correctly. And your customers will LOVE it! I did a set with her and replaced just the prompt set on a voice mailsystem -- nothing else -- the complaints dissapeared. I actually had people ask me what I had done to make the voice mail system "so easy to use." If you still don't know the voice I'm talking about - pick up your phone and dial 10288 - 0700 - 881-4812. (Just listen to the prompt voice - the thing is forwarded to a non-existent number in Lithuania.) Responses, anyone?

A handy way around ever increasing unlisted number charges is to get a distinctive ringing (or whatever your local telco calls it -- Identa Ring, Identa Call, Teenagers' Line...) number on your existing line. Many telcos will not publish (or make available via DA) the second or third numbers - in fact you may have to pay them if you do want a listing. Let them list the 'main' number, treat the second number as your real one, and ignore calls to the main one. You can get a ring detect box if you expect lots of calls on the main number that you don't want to even ring your bell. In many areas that second number costs much less than unpublished service.

Perhaps this may sound a little odd to all of you ... but besides my general interest of telecom stuff (why would I otherwise be subscribed to this service) I also collect phone directories ... and preferably international ones. There are several ways to get them; one of the ways is to buy them from our very own PTT Telecom here in Holland. The problem is that they charge quite a lot for this service. (I am sorry people from the PTT who read this). Another way is to request complementary copies from the telephone companies around the world; sometimes I get lucky, and they send one; often they won't, since there is some ITU regulation on this matter (at least someone told me once). Therefore I am asking the readers here if they would be intrested in helping me to increase my collection of phone directories. I collect also yellow pages. Of course I will pay for the surface mail. At this point I already got all the directories of: - The Netherlands - Zimbabwe - Tchad - Bermuda - Grenada - Macao - Botswana Besides that I've got some directories of: - USA (New York, Los Angeles both yellow and white pages) - France (Paris yellow pages) - Italy (Padova area white pages) - Israel (Haifa area and Tel Aviv white pages in hebrew) =) - United Kingdom (London business directory) - Germany (Bonn white pages) - Belgium (Brussels & Antwerps) If you consider it took me about two years to get this far, you can imagine how much help I could use. Therefore, anyone having some directory laying in some corner of his room ... make someone happy ... send it ... please! Greetings, Alex P.S. And of course if you need a listing or an address write me.

The cable failed Feb. 5 about 20 miles off the Oregon coast. Splicing was completed Wednesday and testing is underway now.

Over the past few months I've gotten several solicitations in the mail to switch to AT&T. One of them was in the form of a check for $40. We currently use MCI, so I called their customer service number. While they don't publicize it, MCI will redeem these checks for their face value in an "MCI Certificate of Savings". And further, for each month that I hold the certificate before cashing it, it's value increases by another $5, for up to 12 months. So, the useless $40 check from AT&T will save me $100 on my MCI bill this time next year!

The number for this service was originally (415) 512-5000, and that number is still working. What makes the situation more interesting is that the service is now being advertised as (415/510/408) 808-5000. This is the first I have heard of an 808 prefix in any of those area codes, and my PBX at work rejects it as invalid. It is also, to my knowledge, the first N0/1X prefix in 408, which I don't think is particularly close to exhausting its supply of NNX prefixes. Does anyone know the telecom story behind this new prefix? Is it set up as a local call in San Francisco, Oakland, and San Jose, with the latter two forwarded to San Francisco, or perhaps terminating with duplicate equipment remotely maintained in those sites? Is Pac*Bell planning to offer any other uses of this prefix or others with the same 7-digit number in all three area codes? Is the call charged as Zone 3 or Local Toll from some areas? If the answer to the last question is yes, caution is warranted for some folks. For example, from Mountain View 415-254, San Francisco (415) is a local toll call, but downtown San Jose (408) is not. A surprisingly high percentage of people still aren't clued in that "toll" and "same area code" are separate issues.

Here's a bit of background (which most comp.dcom.telecom readers probably already know), plus Bell Canada's similar service called Primeline. SAC 500 is the Service Access Code selected by the North American Industry for providers of Personal Communications Services. Wireline and Wireless service providers have intentions of using this code to support Personal Mobility, Terminal Mobility and Service Profile Management. Bell Communications Research Inc. (Bellcore) administers the North American Numbering Plan, and in July 1994 began assigning blocks of personal go anywhere numbers to Telephone Companies and Wireless Carriers across the U.S., Canada and the Caribbean Islands. Stentor Resource Center Inc (SRCI), on behalf of Bell Canada and other Canadian Telephone companies, has applied and received SAC 500 NXX resources from Bellcore. However, no tariffs for related services have yet been filed or approved by the Regulator (CRTC). Although today Bell Canada does not yet offer a 500-based go anywhere service, Bell offers a follow me service called PrimeLine which does not require a 500 number. Customers in Bell Canada's serving area can call 310-BELL (310-2355) from any exchange to obtain detailed information on Primeline. Hope that was useful, Evan. Recently, a question came up wondering why a gentleman from Kingston, Ontario couldn't reach Pat on his SAC 500 number. I tried to call Pat and had the same result. Thinking it might be a technical problem, I asked a few questions. Well, what I discovered is (as we probably all know) telcos enter into agreements with other carriers with respect to SAC 500 service, not only so that calls can be properly routed, but that the appropriate rating and billing can take place, the revenues collected, and settled. To date, no agreements have been negotiated with any US provider for 500 service. Will that happen? Well, that's just not something that I can discuss on a newsgroup!

I had a job working at Cornell's particle accelerator, CESR last summer -- one of the many safety problems that we were warned about were the two thick copper busbars that went underneath the accelerator: these supplied 40 V or so DC for the main magnets; although the voltage is low, really too low to produce a lethal current passing through the body under most circumstances, it is a very serious hazard if you short them out with a ring or a tool held in your hands. Of course there were many other electric hazards, including most of a megawatt of RF power that goes into the accelerating cavities and the linac, several higher voltage distribution systems and a lot of things that can get you hurt or killed. After seeing how much work it took just to keep this little 1-km long accelerator working, the logistic challenge of running a superconducting supercollider just leaves me staggering; it would take a literal army to run it. I'll also say a word about telecommunications at CESR. Throughout the building and under the ring one will find many "beam phones", each of which has a dial with nine positions. To call somebody on a beam phone, you'd turn the dial to a position which wasn't being used, say, number 3 -- then you'd push the page button, announce to the called party that you want them to pick up on line 3, and then they'd do that. ------------------------------ From: Sergei Anfilofiev Subject: Re: Inquiry on CDMA and QUALCOMM Date: 02 Mar 1995 11:11:09 +0300 Organization: ZNIIS Reply-To: sanfi@zniis.msk.su eswu@v9000.ntu.ac.sg writes: > 2) Where to get the published materials on CDMA designed by QUALCOMM? > I have heard that QUALCOMM has designed a CDMA system, but I still > did not find any wirtten material on it.

Bellaire Subject: Answering Machine calls for you! I have noticed that if you call someone's answering machine and immediately hang up when the tape starts that the machine holds the line open for the length of the tape. (This works with every machine I have tested.) If someone calls you, immediately hangs up and you have a long enough message the local exchange has time to reset your line, present you with a local dial tone and start the 'you have waited too long to dial' type message. I've had several dozen of these auto dialed calls over the years. I've also noticed that if you flash and then hang up the switch in my hometown (616-651) likes to reconnect the original parties. It will go as far as redialing BOTH parties at the same time to reconnect this lost connection. This would account for a home phone and a cell phone being called by the switch and then connected to each other. Not all practical jokes are played by people, some are played by machines! James E.

The owner's manual for all these electronic devices tells you to drain down the battery in their device for good reason. The device will shut down when the battery has 3-5% life left, not zero.

As far as using it goes, we've noticed that our line is a *lot* less noisy than it was, so your modem should work even more reliably. We also now get a *lot* more numbers on our Caller ID display than before. Much fewer "out-of-area" numbers. I don't know what we had before, but it had Caller ID too, and a fair amount of crosstalk.

Is it really that hard to get everone to agree: xxx - special service codes (e.g. Info, Emergency) xxx xxxx - abbreviated form of 1+ ten digit dialing, where the area code (NPA) is the same. 0 xxx xxxx - abbreviated form of 0+ ten digit dialing, where the area code (NPA) is the same. 1 xxx xxx xxxx - caller paid, direct dialed call 0 xxx xxx xxxx - alternate billing, direct dialed call Using the long form should *always* be legal. Seven digit dialing might require timeouts (or trailing #). It's really frustrating that I cannot program my cellular phone with autodial numbers that work anywhere I go. Some places REQUIRE a leading 1 for all calls, and some places REQUIRE lack of a leading 1. Harumph. John [TELECOM Digest Editor's Note: Your complaint has validity, however I suspect the people in Pakistan with cellular phones would be quite pleased right now if they could dial *anything at all* on their cell phones. As reported here a few days ago, the citizens of that country found their cellular service suddenly turned off -- apparently perman- ently disconnected when the government was unable to monitor their conversations as it wished. When the carrier there was unable for technical reasons to provide the level of monitoring desired by the government, the government's response was to raid the offices of the carrier and turn it off completely. I wonder if they have since relented and restarted the service or if it is still off.

I find this propaganda piece both strange and outrageous for several reasons. (1) The definition of a telephone line must have been discussed before; after all, delivery of local loops on T-spans predates the MFJ. Surely, you pay the SLC PER CHANNEL on a T-span, no? (2) Since the SLC goes directly to the LEC, the cost to the customer (base subscription plus SLC) should be the same regardless of the amount of the SLC, shouldn't it? If the monthly amount is $10 per line plus $6 SLC, the customer pays $16. If the SLC goes away, the LEC loses the SLC-funded subsidy, so they will have to charge $16 per line per month. The difference is entirely in the bookkeeping of amortization and depreciation allocations. (3) If the SLC is mandated by FCC, I would think that the amount would be standardized across the country. How can it vary with the Bell Atlantic Service Area ? What is going on? Is my point two above completely wrong?

I'm astounded that the university can't make an accommodation for your needs whether they be modem, FAX, or a second analog voice circuit. With standard telephone wiring all over the place, it's just a matter of crossconnecting the pair to some other circuit that goes to a central office instead of to your PBX. If this is a matter of money, that you don't want to pay to have it done, then that is another matter, and you'll just have to deal with that.

So, if the phone rang and the caller asked for Mr. or Mrs. Smith (or whatever it was), she knew right away that it was a telemarketer. Worth a try, I think. A philosophical question: why should a telco charge to keep a number unlisted? It doesn't seem like it would cost them anything (one more field in the customer record), and would save them printing a few pages in the directory. Atri [TELECOM Digest Editor's Note: In the old days when telco did not charge for directory assistance, they charged for non-pub listings simply because people could not find the number in the book (obviously) and would waste the time of the DA operator trying to find it from her. That was the reason for the 'added cost of a non-pub phone'. Now that everyone pays for DA whether you get anything out of them during the conversation or not, it would seem to be hard to justify charging the subscriber also.

Pat, You are right [as usual ;=) ]. Let us assume for a moment, that someone had the time, some of the money, and desire to change the above situation, and create a sutuation where your name, calling (as opposed to billing) phone number, and ABOVE ALL YOUR *actual* (as opposed to your billing) ADDRESS, are not going out over the network, and often to the called party. In the opinion of you, and the other readers of this list, is such a thing 1) possible; and 2) desireable? Thanks, Glenn L Foote ...... glnfoote@freenet.columbus.oh.us [TELECOM Digest Editor's Note: I'd think it would have to be an individual decision on a case by case basis. The closest we come to that scenario now is the ability to block Caller-ID as desired, and in actual practice that ability pretty well preserves your privacy even though it does impose some effort on the part of the caller.

In fact, this "next time to register" value is saved in the EEPROM. Also, there is another type of registration which occurs when the SID (System ID) changes which basically occurs when the phone changes cellular systems. The transmitted information is the same. I got this information based on the US analog (TIA-553, NAMPS, etc) call processing specifications. The new IS54B digital TDMA ( and IS54C) standard has a more complex registration mechanism which involves Location Area IDs (LOCAIDs) and power up and power-down registration. IS54C supports registration on the Digital Control Channel as well. George C.

Unfortunately, like a great deal of proposed legislation, on the face of it sounds inocuous enough. However, we have learned over the years that inocuous sound and intent may not be enough by the time the enforcement guys and the lawyers get finished with it. It is certainly POSSIBLE that the EFF and company are overreacting. But at the same time, we have to recognize that when it snows, those boys in Washington have been known to get a bit out of hand on occasion :-) Although I have no personal conversations with Senators Exon or Gordon to back this up, it is possible that the INTENT of the words "MAKES, TRANSMITS, OR OTHERWISE MAKES AVAILABLE ANY COMMENT,REQUEST, SUGGESTION, PROPOSAL, IMAGE, OR OTHER COMMUNICATION" is meant to apply to the INDIVIDUAL initiating the act, NOT to common carriers, etc. The lack of clarity MAY be a result of poor staff work, not uncommon in Washington. (Note carefully the emphasis on INTENT and MAY.) However, I also know that if this thing were to hit the books, the original INTENT will be long lost and we will be left with the words -- words easily misused by overzealous enforcement, special interest lawyers, etc., to further their own agendas. In this age of international communications, it is patent nonsense to think that short of massive banks of real time censors on all international circuits, or cutting all international communications, that this could be enforced. I suspect that Senator's Exon and Gordon were at lunch when we rediscovered the outside world. At the same time, I share your views on the loss of the sense of shame, personal responsibility, etc. It seems that nothing is too excessive, too disgusting, too degrading for this ENLIGHTENED age of ours. Unfortunately, calling for a greater emphasis on parental responsibility to protect children is truly "whistling in the wind" -- it hasn't seemed to work when it comes to drugs, guns, sex, etc. (How can it when the parents don't seem to have any sense of responsibility to pass on to the kids.) Although the sociologists and psychologists would most likely disagree, an enormous number of the problems of our society would be corrected by some TRUE parenting, the timely parental application of the word "NO", and an occasional pat on the backside (no pun intended.) All of that notwithstanding, I don't think that we can let this thing get enacted and I plan to write to my Senators to register my objection. A final note. Your commentary included a closing statement "but with the United States Congress controlled as it is today..." It should be noted for the record that the bill is named for and sponsored by Senator Exon, DEMOCRAT of Nebraska. This little piece of wackiness might get passed by a Republican controlled congress, but the liberals among us should take note that this little gem originated on the left side of the aisle.

You don't have an attorney who has good friends working for the government; the kind who makes lewd noises when he smacks his lips and sits at the bar drinking with the judge and the prosecutors while cases are settled in conference and outside the courtroom. Therefore, the law *will* apply to you, thank you. The big boys can whine about their 'policies and proceedures' and how the computer will let them do one thing and won't let them do another and everyone will sit agog and in awe taking it all in. That won't work for you, John. You knew or should have known what 'they' were doing. And as you point out, the federal government has a way of stretching and distorting the meaning of all kinds of things. I'm still having real problems with this whole thing for myself. In the many years I have listened to the ACLU and their arguments and the few years I I have listened to the EFF present their views, I've have never once been in agreement. Thousands of ACLU cases; I can tell you what I find wrong with their position in every one of them. Long time readers will recall a source of derision here in this Digest are what I term the Socially Responsible Computerists, based on the group whose name includes those words, as in "I am glad I am not Socially Responsible, nor would I want to be". But anymore, I just don't know ... as Brad Hicks said in an issue of the Digest earlier Thursday, it would nice if the lynch mob could be a little more honest about their intentions. It would also be nice if Exon and Company would rewrite that proposal eliminating any ambiquities or questions. You are also correct that for the most part it is useless to demand that parents require accountability and/or personal responsibility of their children. After all, what would they (the parents) know about it? Now that we are into the third generation after Doctor Benjamin Spock, the old ways have been forgotten by most people, if they ever experienced them at all. They simply raise their children the way they were raised; they don't know any different.

My company, Parallel Technologies Corp., a NY State Subchapter S Corporation, tried to get cell service from Cell One/Boston and NYNEX. Heh. The results were so negative it was not even funny. Cell companies generally check for corporate listings on TRW or D&B; at least these two did.

But they were happy to send me and/or any possible creditors a sheet saying that I wouldn't be listed with them. End of story. Then I talked to D&B. They took some information and assigned me a DUNS number. Now I'm listed with D&B. However, they will not have any financial information on my company until a client requests the research be done (for some add'l fee). I eventually got fed up with it and asked a friend with a big company and a 4A1 rating with D&B if I could get service with a name of "Big Company, c/o Parallel Technologies Corp." That worked. Cell companies are really paranoid when it comes to small businesses with phones. My advice: get it with your personal credit and have your company reimburse you. Hope this helps.

Making an anonymous telephone call is perfectly legal; it is only if the call is HARASSING or THREATENING that it is illegal, whether or not it is anonymous. Further, my right as a caller to expect privacy does not disappear simply because the person I called CLAIMS that my call was obnoxious, or even harassing or threatening. Releasing the number of the caller to the callee is not in any way necessary to deterring illegal nuisance calls. Another point to consider is your specification of "a RESIDENTIAL customer." The existence of such a right should not be contingent on class of service. Whatever rights I do or don't have for protection from nuisance calls should be the same on my phone at work as for my phone at home.

I, for one, would not be willing to toss the privacy rights of the caller on the trash heap merely on the strength of a "claim" by any given residential customer that they found the call "obnoxious." There has been ample discussion of all the reasons against Caller-ID, or at least in favor of blocking options. Many of these reasons are very "good" ones, and in some cases arguably protect the very lives of the callers involved. I won't rehash them all here. Now I ask myself if, potentially, for each person with one of those "good" reasons for protecting their privacy, there might not be someone else with a residential phone line whose ethics are so unbelievably twisted that they might actually stoop to "claiming" that at such-and-such a date and time they received an "obnoxious" call, and would Telco please supply them with the number. Anybody with any motive can claim anything; I'd want them to be able to prove it. Given the choice, I'd rather not have my privacy violated by anything short of a court order, thank you very much. And just so there's no confusion about how good a reason has to be before it's "good enough" in this context, I think the list of "good" reasons for privacy should should start with: 1.

Could someone please explain > what these terms mean? You may already be aware that a T-1 circuit is a bi-directional serial connection, sending and receiving at 1.544 Mbps (million bits per second). Each second, 8000 data frames are exchanged (in both directions, send and receive). Each frame consists of 193 bits: 24 eight bit channels plus a framing bit. ESF and D4 refer to the "framing format" used on any particular T-1. When a T-1 starts up, or "frames", it picks a bit going past and assumes it is the framing bit. Every 193rd bit after is examined and compared to an expected pattern. As soon as the pattern is violated, the next bit in sequence is chosen as the framing bit and the comparison begins again. This process is continued until the actual framing bit is found and the line established, or too many errors are encountered and the line fails to start. Once framing is established, it becomes possible to locate the 24 data (or voice) channels and exchange information. D4 is probably still the most common framing format (lets not start that again), but ESF is coming up fast. D4 simply allows the terminal gear to locate the payload channels, plus a very crude ability to signal the far end that problems have interrupted the line (when appropriate). ESF (Extended Super Frame) also "frames" the data, but additionally includes tha ability to send operational messages end-to-end, and provide a level of line quality reporting. This is done by organizing groups of 12 frames into "super" frames. With processing power, the line can stay framed while half of the framing bits are borrowed to form a message channel. A CRC scheme is used to calculate line quality, detecting about 93% of error conditions. There are at least two common flavors of ESF, a proprietary AT&T scheme and an ANSI scheme, T1.403 I believe. Be sure you know which one your terminal gear supports. If you are running data, you may also want to check on the "line coding" format, AMI (Alternate Mark Inversion) or B8ZS (binary 8 zero superssion). In the past, all T spans were AMI, which limited the ability to send strings of zeros. All "ones" were sent as alternating polarity pulses (to keep the DC component low) on the line, and "zeros" were sent as the absence of pulses. Obviously, too many zeros and the line would quickly lose synch. B8ZS is a scheme to avoid the line dropping while sending unlimited zeros. For reasons that I have not gone into, if you want to be able to use the full 64kbps capacity of each channel (instead of just 56kbps) then you want B8ZS. Hope this helps. Mike D.

In my opinion: Chances are 99+% that this is a scam. There have been several companies that have been busted for this type of activity. Some of the "offices" were nothing more than boiler room operations. I've even seen a story on one of the news magazines. I used to live in Southern California, and they busted a couple of operations out there. For some reason, lots of phone scam folks set up show in southern CA, probably in hopes they will sound successful and legit. As far as the filing fee, I think the FCC charges a couple of hundred dollars. The first come, first serve basis might also be in question. I know the FCC has had a freeze on some SMR applications. Don't know if it was all, or just a subset. From a technical point of view, one channel does not make an SMR system. They must have a site in mind for the license. If you are still intersted in checking into this, ask them to send you a copy of the application form, showing the site coordinates and antenna elevation. Ask them about the channel loading plans and if they plan on filing for slow growth vs. normal. This has to do with how long they have to load up their channels with users. I think you have to reach around 75% loading in under five years, but I can't remember the exact details. My guess is they won't be able to answer your questions.

Nextel is a big player in the market. I bought some of their stock while I was at my last job. Then my new job sent me overseas for a few months and the Nextel stock dropped by about 70%. Guess I hold it for a while. From what I understand, Motorola is having some delays with their MIRS technology. I've seen a demo at my last job and it looks like it has potential, especially for wide are dispatch operations.

I don't know that there are any companies looking to buy "second hand" SMR channels these days. I am probably wrong here, but from what I have seen in the market, Nextel has all the channels it needs for now, and if they are looking for more, they will go to the FCC to get them. > My questions are these: > Is this really a good investment?

Before I would spend any money, I would call some of these companies and ask them myself! If this is a great bargain, and these companies are really demanding these channels, how come this company selling them to you doesn't go after Nextel, CenCell or Dialpage themselves? I would think they could get a lot more money from selling it directly to these companies. I may be offbase here, so someone jump in and correct me if I am wrong. I think you are getting ripped off.

Whatever rate you want! Usually, there is a table that is built that has default rates. These are not exact (since the rates change faster than my underwear) but they do not need to be close. The intent is to get close to the rate as possible. A markup is then set for each type of call (like 800, local, etc). I used to markup hotel calls as much as 200% (depending on the hotel). If the hotel is a five star hotel, they can get away with big markups.

Something doesn't seem right here. You need a copper pair for *each* telephone line that's delivered. You can't "bridge" a line across the two other existing pairs. What *could* be done is that a device called a SLC-1 might be installed. It allows two lines to operate over a single pair. The device has two "ports". One is called the "physical" and the other is called the "theoretical" or "derived" port. I would recommend that you try having the modem on the physical side. The derived side (since it is a "carrier" type operation) doesn't always work really well with modems. Telco's usually hate to install these beasts. They have batteries that need to be replaced every so often, even though they recharge when the physical line is idle. I've only seen them installed twice. Once was a situation where there were *NO* pairs left in a cable. The only way to get a customer back in service was to put up a SLC-1 out at the terminal and hook the two loops into it. It was a temporary measure until a work order could be issued to rehab the cable run. The other time was for an Arbitron line in a house out in the 'burbs that only had a single pair buried loop feeding it. The line was a temporary line for about three to six months after which it would be disconnected. The decision was made to SLC-1 the Arbitron line rather than have to run a new buried loop through the woods to the house (that was partially set *into* a hill).

You can control how many rings each destination will receive before switching to the next number in the list, and you can change the list as often as you want. You can also temporarily override the list without purging it (for vacations, etc.).

A digital PBX provides digital phones (usually over one or two pair wire) with lots of features only possible through digital phones. In addition, they are usually capable of interfacing directly to any T-1, ISDN or other facility. They also support analog trunks. Some can even switch data with the voice (after all, everything is digital). I used to work on a system that actually converted the voice to digital inside the telephone, and packetized the voice.

SLC96 has a mode (MODE II) where 48 customer channels are served by 1 T1 (24 channels) which are switched via a time slot interchanger. if more than 24 of the 48 customers try to go off hook, (ie the 25th) they are denied dial tone. Other SLC systems (DMS-1 Urban, RTEC DISC*S) use similar approaches.

Works fine, except for all the "Out Of Area" on long-distance calls. Only thing slightly wrong is when I call home (301-345, College Park, MD) from my cell-phone (301-648), the landline switch doesn't send its caller ID.

[TELECOM Digest Editor's Note: It was through him that I met the author Ayn Rand. In 1957 she was on a tour promoting her (then) new book Atlas Shrugged. Since Erickson was in charge of all the special assembly programs at school, he invited her to be a speaker at one of the assemblies when she was in the Chicago area. I still have a hard- cover personally autographed copy of Atlas ... even promoting her book she did not come cheap; it used up quite a bit of the budget the school gave him for assembly programs. After school that day, he had agreed to drive her to Ohare Airport where she was getting a flight to go to the next stop on her itinerary, and he let me ride along. We stopped for dinner on the way and chatted while waiting for dinner to arrive. It so happens either that day or the day before -- I can't remember -- a very lengthy book review of Atlas Shrugged appeared in the {Christian Science Monitor}; a much longer book review than they usually did in those days, about three full page columns. She had not seen it so I gave her a copy which interested her quite a bit. She sat there for ten minutes or so reading it with that long cigarette holder in her fingers which was her trademark. She'd puff on that occassionally, and sip her martini as she read what the {Monitor} had to say. She had a habit of staring intently at people, and after she finished reading and was back to staring at me, finally she spoke up and said, "Such an intelligent young man! Too smart to believe in Gott! Why do you believe in Gott?" I guess I was startled and did not have any answer for that. Erickson in the meantime put a newspaper in front of his face and pretended to read it so he could hide behind it and laugh without her seeing him. I was 14 at the time; when I reached in my pocket brazenly and pulled out a cigarette (they were 23 cents per package at Walgreen's Drug Store) both of them nodded approvingly and Ms. Rand immediatly produced a lighter to light mine and the one Erickson produced, then she lighted her own. I stayed in touch with him for several years after I got out of high school, stopping in occassionally at his place to say hello. The visits got fewer and further apart, and about ten years ago there was a period of six months or so I had not seen or spoken to him. I tried calling his home number and it was disconnected. I called the school, and talked to Bill Mueller, who was literally the last of the teachers still around from when I had been there -- over the years the whole crew had retired or otherwise left. In fact he was on his final year of teaching, due to retire himself after thirty plus years of teaching at the end of that school year. He published a newsletter every three months or so which went to all the teachers who had retired in the twenty years or so after I graduated. I asked him how was Erickson doing and could I speak to him on the phone for a couple minutes. Erickson was not there. It seems about four months earlier he had not shown up for school one day. The school day started and the kids in his first class were standing around in the hall because his classroom door was locked. He hadn't shown up about a half hour after that and Bill Mueller said, "We tried calling him at home on the phone and did not get any answer so a couple of us went over to his house; he lived about two blocks away from school. When he did not answer the door we went in with the spare key he left at school and we found him dead. It was the result of a kidney infection he had had for several months which simply would not go away, despite his medication."

There is a reason that the manufacturers put features like this on electronic devices. It's not because they want the device to "die" mid-conversation, it's because they have spent lots of $ figuring out the best way to extend battery life. Stick with the manufacturers recommendation. If you need to talk longer, get a spare battery pack. On most flip-phones you can change the battery during a conversation. You have to be quick, but it is a feature of the phones. Another less convenient option is to buy or build a 12v battery back (I built a 4A pack for about $25 in a pretty nice case with a carry strap). Buy the cigarette lighter plug accessory for the flip phone and then plug it into your battery pack. This will give you a couple of days of standby and several hours of talk-time. I use mine if I know I'm going to be away from the charger for awhile (like at a transmitter site for an extended outage or allignment session). I built another one of these for my brother. He takes it out on his boat on weekends and talks quite a bit with no problems at all. Just a couple suggestions. Take care.

Dave, lots of folks will try to explain this to you, and most won't know they don't have a clue what they're talking about. To fully understand the differences between ESF and SF (D4) is a long explanation. Ive tried to put some of it into several of my postings with limited success. My suggestion to you is to order a book called The Guide to T-1 Networking. It is available from the Telecom Library Inc, 12 West 21 Street, New York, NY 10010. Call 212-691-8215 or FAX 212-691-1191. It is a paper back 8.5 x 11 size, 269 pages, ISBN 0-936648-26-0. It is well written, covers what you want to know, and requires no propeller on your beanie to understand. I have ordered many books from the Telecom Library folks over the years (you can also get Harry Newton's dictionary from them -- everyone should have this book) and they respond very quickly. After reading it, if you're still confused, you might want to check out our two day on-site only seminar Learning to Talk the Talk and Walk the Walk of Telecommunications. Much of what most people need to know about this industry can be easily understood if a person has the fundamental concepts correct and in logical order. Most do not.

This illustrates the almost periodic fading for a receiver moving at uniform velocity. Many papers have been published on delay spread. A review paper with many refrences to earlier work was published by prof Rappaport of VPI (Virginia Polytechnic) about three years ago in IEEE transactions. The GSM COST committee has also collected many measurements on delay spread during the development of GSM technology during the 1980s and these were published in both IEEE and IEE and other European journals from about 1986 onward. The report by Rappaport et al was also published by the CTIA (Cellular Telecommunications Industry Association) who commissioned the study to address the question of the need for an adaptive equalizer for North American TDMA cellular. The power spectrum of a test signal transmitted via a multipath medium will be similar to that of the original signal, although the phase will be different. If the receiver antenna is in motion (or the scattering objects in the environment are moving) the spectrum will be broadened due to the differing Doppler shift of the various multipath components. This effect is very small and difficult to measure and I do not know of any published measurements. The effects of multipath are better displayed by looking at the first two types of data. Incidentally, the CTIA is in Washington, DC, and should not be confused with the TIA, which is a different organization and does not have the report in question. The telephone number of the CTIA is 202 785 0081. Please be prepared to pay for the cost of copying and mailing the report. ------------------------------ From: levine@seas.smu.edu (Dr. R.

I bought a similar device a couple weeks ago at an office supply store (Staples in Phoenix, AZ). It's called "VOICE IT". It records a total of 40 seconds in up to 12 separate messages. In addition to REC and PLAY buttons it has a MESsage button to go to the beginning of the message list, previous message and next message buttons ( |< and >| ), and ERASE ALL and ERASE LAST buttons which you must hold down for about 1 second. Each press of PLAY plays the next message in the list. New messages recorded go on the end of the list. It's the same size as a credit card and about 1/4 inch thick. It was $49.95 (the store claimed suggested retail was $59.95). I don't know how long the four dime-sized lithium batteries will last since I haven't had it very long. The voice quality is good, better than I expected for a device of this size. I find it very useful while driving and I hear a phone number or a song title on the radio that I'd like to remember, or when someone gives me an address or phone number on the phone, I don't have to fish for a pen and paper.

[This copyrighted article is forwarded to RRE by permission.] Date: Wed, 1 Mar 1995 12:53:16 -0800 From: rsadl@max.sosc.osshe.edu (Russell Sadler) I am enclosing a column I wrote a couple of weeks ago. I am a very mainstream, mass media journalist. For the last 25 years I have syndicated a daily radio and television commentary and a weekly newspaper column. The broadcasts are carried on five commercial television stations and six radio stations in Oregon and Northern California. Two radio stations are public, the rest are commercial. The column is carried in daily and weekly newspapers around Oregon. I think you will find this column is a different explanation for the new congressional leadership's effort to "defund" public broadcasting. *********Begin Column********** Rupert Murdoch, the Australian media baron, stupefied the media business when his Fox network outbid the venerable CBS for the rights to broadcast National Football League games this year. People in the television business knew Fox did not own enough stations in the top 50 media markets to charge enough for commercials to recover the $1.6 billion Murdoch spent taking the NFL away from CBS. Rupert Murdoch is no fool with his money. The industry waited for Murdoch to drop the other shoe. There was less surprise when Murdoch announced his holding company paid $500 million for a 20 percent interest in the New World Communication Group, Inc. New World owns six television stations in the top 20 markets, four in the top 50 markets and two in the top 70, including stations in Dallas, the 8th largest market and Detroit, the 9th largest. Murdoch switched most of these stations from CBS affiliates to his Fox network. Now Murdoch had the means to charge more for commercials in the NFL games. Despite this brilliant high stakes entrepreneurship, Murdoch apparently lost $350 million in his $2.1 billion bid to build a national network. He needs more stations in the largest television markets. There are no television frequencies available, especially the more lucrative VHF channels 2 - 13. They are licensed to ABC, CBS, NBC and Fox affiliates, a variety of independent stations and public television stations. Enter Big Bird and Barney, two of public television's artistic and financial success stories. The new Republican leadership began a campaign to convince the American people Big Bird and Barney and their "elitist" audience were responsible for the national debt. Government has no business doing what private enterprise can do better, chanted the ideologues. They do not explain why the vast wasteland of commercial television did not produce its own Big Bird and Barney instead of Teenage Mutant Ninja Turtles and Mighty Morphin Power Rangers. Sen. Larry Pressler, R-South Dakota and chair of the Senate Commerce Committee announced Bell Atlantic was prepared to take Big Bird and Barney off the government's hands and syndicate it to cable, satellite and television outlets. Americans could still enjoy Big Bird -- for a fee, of course. There is a hollow, leaden ring to this heated, ideological rhetoric. Congress spends about as much on military bands as it spends on public broadcasting. Pressler comes from a sparsely populated state that has one of the largest public broadcasting audiences in the country. It can't be the money. Pressler can't be reflecting the views of his constituents. Congress really isn't after the public broadcasting's liberal bias - real or imagined. It turns out the new congressional leadership wants the public broadcasting channels, especially in the top 50 markets. Public broadcasting licenses are owned by a variety of state and local governments, non-profit groups, colleges and universities. If the congress cuts public broadcasting funds and these stations are forced off the air, the government can reissue the licenses. Guess who is waiting in line. Shortly after Murdoch's Harper Collins publishing company offered House Speaker Newt Gingrich the controversial $4.5 million book deal, Murdoch and other broadcasters asked for and got closed door meetings with House Republicans and Pressler's Commerce Committee staff. No one knows for sure what went on in these "private" meetings but reporters for Newsday and Los Angeles Times columnist Lars-Erik Nelson believe turning public broadcasting channels over to private broadcasters was a topic of discussion. Bell Atlantic tried to make a deal with Murdoch last year for the 20th Century Fox film library worth an estimated $4 billion. Murdoch wants to sell, apparently to raise cash to replace the money he is losing on the NFL. Bell Atlantic has cash from its telephone operations and wants the film library to supply its planned venture into home entertainment. The deal fell apart when Bell Atlantic decided it did not have enough broadcast outlets to pay the bill. Bell Atlantic executives met privately with Pressler to complain about the lack of broadcasting frequencies in major television markets. Privately, the new congressional leadership believes public broadcasting stands in the way of restructuring the new electronic media and the solution is just turn off the spigot that pays for Big Bird and Barney. The federal government holds a 13 year lien on any public broadcasting facility built with grants from the Corporation for Public Broadcasting. Those facilities include much of the modernized studio and transmission equipment in the largest markets and the extensive translator networks built by rural public stations like Jefferson Public Radio. If these stations cease broadcasting because of a lack of money, the federal government can just take over the property, issue the licenses to private operators and sell the lucrative studio and transmission facilities to their campaign contributors. There is a surprising reason for this intense interest in old-fashioned television stations in the age of cable, satellite transmission and optic fiber cables. Murdoch's satellite television service demonstrated a revolutionary transmission technology that compresses signals 8 to 1. Stripped of technobabble, that means within a decade it will be possible to transmit eight separate digital broadcast signals on television channels that can only transmit one now. If existing television stations can deliver 30 or more channels of home enetertainment into the Top 150 American television markets, it will drastically alter the economics of the cable and telephone industries. Murdoch's compression technology will permit today's commercial and public television broadcasters -- long dismissed as technological dinosaurs -- to compete with cable, telephone and satellite transmissions companies or even short-circuit their potentially lucrative market. Perhaps the bitter battle over Big Bird and Barney's future makes a bit more sense now.

The problem was with automatic answer: the modem seemed unable to hear CNG tones when an answering machine or handset was also online, despite the manufacturer's claims. Wayne Kosten suggested I make sure the modem was the first thing T-d off the incoming line. I did this by running a new line down to the junction box, and tieing it to the first set of connectors. It worked like a charm! Now I have to figure out how to do this right: I piggybacked on top of another pair of wires that was already there, and I'm sure this connector isn't designed to do that (it's the type where all you do is push the insulated wire in, and the connector cuts the insulation and clamps down on the copper. I'm out of places to plug into -- are you allowed to daisy chain? The telephone tech who installed this box brought in six pairs on the incoming line, only two of which are in use. I could disconnect one of them, I suppose, and daisy-chain line 1 down to a lower row of connectors. Am I making any sense?

Yes, I rather suspect it *is* really that hard to get everyone to agree to support this. The vast majority of the NANP prefers to use 1-NXX-NXX-XXXX for *all* long distance calls, both intra-NPA and inter-NPA.

Can a modem > be used to intercept the information and pass it on? Brian, A modem that supports Caller ID might be the answer. All you need to do is open the comm port at 1200 8N1 (I think) to read the data. The Rockwell Chip Set requires that you send the modem "AT#CID=1" to get the formated Caller ID (DATE=, TIME=, NBR=), unformated is "AT#CID=2". DO NOT forget that some Bell companies block the data stream, only to offer it as an additional service. The Caller ID info is sent between the 1st & 2nd Ring. Depending on your Voice Mail Card, you should have no problem in working with your Caller ID Modem and Voice Mail Card. As a 'FUN' project, I am programming my Big Mouth Voice Mail Card to answer based on Caller ID data returned from my Zoom Modem. (If I spent the time, I could do it all on the Zoom card; I don't have the time to re-write my code for the Zoom card ... although it's real easy ... can be done in BASIC!)

Kimberlin <0004133373@mcimail.com> Subject: Local Competition in North Carolina Observers of U.S. telecommunications demonopolization history may recall that in early days of events like Hush-a-Phone and Carterfone, significant news focused on the Mebane Home Telephone Company of North Carolina. Mebane was the battleground upon which the North Carolina Public Utilities Commission and the Federal Communications Commission did battle concerning whether or not the public could own and attach its own telephones to lines of the local telephone company. At one point, the NC PUC even issued a widely-ridiculed decision that it would permit the public to connect its own telephones for interstate traffic only -- but that in order to do so, users would have to rent a separate telephone line to be used for interstate calls only. Saner heads eventually prevailed, and the matter was resolved by other means. Today, North Carolina appears to be among the earlier states contemplating statewide demonopolization of local telephone service, perhaps beginning as early as July 1, 1996. A bill was introduced into the North Garolina legislature only several weeks ago, with nearly enough co-sponsors to assure passage at introduction. Here's a story from the March 3, 1995 Charlotte, NC ... And so there you have it, Dear Moderator. I coincidentally note it was five years ago and less that my posts forecasting the demise of local competition in the U.S met with replies of incredulity in this forum, mostly from those who were certain the long-standing claims of massive capital cost would maintain the once-sacrosanct "natural monopoly" concept of 1913 in perpetuity. Yet, today, we see instead the telephone companies in North Carolina seizing the initiative to change their own status. Clearly, they have gotten the message as demonstrated in places like England and New Zealand that it's no longer such a massive, capital-intensive task to construct and maintaim a functioning local telephone plant. ------------------------------ Date: Fri, 3 Mar 1995 17:03:14 -0500 From: richard@mandarin.com Subject: Major UK Network Failure On the morning of Thursday, 2 March, workmen accidentally cut into a major fiber-optic cable near Banbury, which contained BT's main telecomms link between London and Birmingham. Details of the incident are not yet completely clear, but it is reported that approximately 18 fibres, each carrying 540Mb, plus the associated maintenance spares, were broken by the damage. Serious congestion followed - not only on BT's network, but also on other networks as customers and service providers tried to reroute their traffic by other means. Several of the mobile networks, who lease bulk capacity from BT, also suffered consequent disruption: as did JANET, the "Joint Academic NETwork" in the UK. This incident has raised some significant questions about BT's claims to have a resilient network, and to be able to reroute around a single point of failure. It took BT until late in the afternoon of the following day (Friday, 3 March) before service on the route was fully restored.

If the number is > direct dialable, then it can be used. In most places where the local > numbers are less than seven digits, you will find the city code and > country code are longer, to fill in the blanks. The country originally referred to (the Falkland Islands) now has five digit numbers. Until recently there were only four digit numbers, and then they all changed to five digit by prepending all numbers with "2". International dialing to the Falkland Islands has been on +500 for as long as I can remember; before that it was operator-only connection via Cable and Wireless. Some of you may recall that the failure of the Cable and Wireless link just before the Falklands were invaded, was a point featured in a film made subsequently about the Falklands war. Obviously the service has since been improved -- possibly as a result of improvements in funding? There are no "city codes" for the Falklands Islands. It is unlikely that there is even more than one CO. So the Falklands have some of the shortest (international) numbers in the world, and from the UK dialling the Falklands takes less digits now than most inland numbers. Oddly enough, calls to the Falklands are also the most expensive calls (apart from Satellite and Ships calls) that can be made from the UK. As in the US, 500 has a special purpose in the UK -- it is one of our freephone (toll-free) codes, like 800. So if the initial digit 0 is repeated by accident, a call that should be free (such as 0500 224466) turns into one of the most expensive calls (00500 22446) that can be made. I believe there may still be shorter numbers than those in the Falklands, but until recently some of them could not be dialed in the normal way as Telco's equipment could not handle them correctly. Callers had to dial a dummy digit *after* the called number, to convince the COs that the digit string is valid. Either the numbers have been lengthened, or the COs have been fixed ... we no longer have to dial dummy digits.

Is there an 'international standard'? Is it official or just commonly accepted? The guy I was debating with said that +1 814 555 1212 was the 'offical' way. What does the '+' mean? Jeff Wolfe Sysadmin, Newsadmin - Penn State - College of Earth and Mineral Sciences [TELECOM Digest Editor's Note: The '+' means 'international access code if required plus'. In other words, to dial a country in Europe for example, we dial 011 plus the country code and number. In the USA, '1' is by coincidence both the access code used internally when dialing long distance and it is the international access code for the USA and Canada when dialing here from elsewhere. So the way you would read your example is 'dial whatever you dial to place an international call, followed by 1 for the USA and then the area code 814 and local number 555-1212'.

The problem with Pizza Pizza's system is that the famous 967-1111 works only from within the 416 area code (Metro. Toronto). Local callers in the surrounding 'burbs have to dial 416 967-1111, and callers further out have local numbers (e.g. Oshawa 905 567-1111) to reach their local dispatch centre. In fact I think there is only the one central dispatch site for all of southern Ontario. It's interesting to see the different approach taken by the chains. Pizza Pizza has all calls go to one place, and then sends the orders to the geographically appropriate store on a data network. This lets them track how busy each store is and avoid overloading by farming orders out further afield when necessary. I doubt that any phone-network based routing scheme will have such flexibility. Pizza Pizza has an overwhelming market presence in the Toronto area, to the point that customs people at the airport are reputed to ask suspicious travellers claiming to live in Toronto "what's Pizza Pizza's number?", or even to ask them to sing the little jingle "nine - six - seven -- eleven -- eleven". A number of other local chains have catchy numbers (Two-for-One Pizza is 241-0241 Get it: 241- oh - you did get it...), but nothing has close to the recognition of Pizza Pizza.

Pizza Pizza pioneered the single number for an entire city, covering multiple outlets. (Far in advance of Dominos in the US, for example.) But the Pizza Pizza system has two limitations, compared to the new one at Pizza Hut: 1. The Pizza Pizza number only works within the Toronto free calling area. Its long distance (or a different local number) from other areas. 2. The Pizza Pizza number goes to a central location, where the call is answered and the order taken. The order is then transmitted to the nearest franchise store by a data link. By contrast: 1. With the new service, Pizza Hut has the same seven-digit number (310-1010) over multiple area codes. The caller never has to dial a long distance call. 2. The public network automatically routes the call to the nearest Pizza Hut store, based on the caller's location. So there is no need for a central answering location or retransmission of the order. Actually, Bell Canada's 310-Service is just 800-Service in disguise. The rates (to Pizza Hut) are the same as 800 rates, with a premium charge added for using 7-digit access. The idea is to let multi-location companies have a "local" appearance, but only one number to advertise.

To communicate with this pool we are using the windows nasi redirector (attnasi 1.0 loaded at windows startup) from NOVELL which redirects COM1 to the modem pool. As remote control software we wanted to use ReachOut because this supports Super VGA 1024*768. ReachOut doesn't seem to work with the modem pool (COM1 is not redirected) because it makes no use of the standard windows communications API. Can anyone tell me which remote control solution supports SVGA 1024*768 or higher and is able to make use of a modem pool through the windows nasi redirector mentioned above? Because of memory problems we're not able to use the DOS nasi redirector. We are using NetWare 3.11, IPXODI 2.12, NETX 3.32, Windows 3.1 upgraded to 3.11 (NOT WfW).

Barrie told the story of a call he got at 2 am one morning from someone saying "you called me". He was mystified for a while until the mystery caller identified his last name. It turned out Barrie was trying to reach someone else with the same last name (two listings were found for the surname; call attempt #1 was for the mystery caller who didn't answer at the time; attempt #2 was the person being looked for). Caller #1 had a call display unit that recorded the Caller ID transactions, and thus Andy Barrie's unblocked call would have shown up as one of the calls. The commentary was on the CFRB 1010 access line at +1 416 872.2372 (872.CFRB) - select 4 on touch tone to hear the feature commentaries; Andy Barrie's material is then obtained by selecting 2). This will likely be replaced with Barrie's next commentary as of Monday 6th March.

I'm looking for a way to interface an IBM ThinkPad 755 series computer with an INMARSAT-A ground station at 64 Kbps, without using a seperate device such as a router. Since the TP's onboard serial ports can't support this, I am thinking that the only way to pull this off is via some sort of PCMCIA interface, that could support sync. PPP at 64 Kbps (externally clocked). Does anyone know of anyone that makes such a beast? I know about ISA boards that can do this, but the TP has to operate (in this context) without a dock, so it's only the onboard interfaces or PCMCIA gear that works.

This tape includes both his talk and the question period. (It is also available on Internet Talk Radio for those willing to consume that much bandwidth, and possibly spend longer downloading the file than the playing time of the speech.) Barlow primarily discusses the cultural conflict between the traditional Internet and the new commercial interests generally identified with the "information superhighway". There is discussion of government, cryptography, censorship, and the evolution of the aims and work of the EFF. One point reiterated throughout is the need for those deeply involved in the technology to study and become involved in the political forces which drive the use (and abuse) of advanced communications. A minor theme is the call for "rich media". Barlow laments the fact that human beings assimilate text at a very low rate (generally below 1200 bps), but take in experience far faster. Rich media (or multimedia) are therefore much more efficient for human communications purposes. Barlow ignores two, very vital, factors here. The first is that the bandwidth requirements for non-text messages are currently very expensive, and promote a dependence on an elite level of technology. (This is interesting in view of the link with Internet Talk Radio). The second consideration is that, despite almost a century of involvement with multimedia, people seem to be only marginally capable of generating communications in non-text forms.

Last fall, there was one number (662-5555) that was for the entire metro area, and they did the routing of the pizza order themselves. Now, a call to 662-5555 gets you to a person who asks your home phone number (don't they have caller ID?), and asks you to dial the Pizza Hut in your area (and supplies you that number).

The difference is that 967-1111 went to only *one* phone number (or hunt group) and Pizza Pizza dispatched the nearest franchise to take the order. With Pizza Hut, the 310-1010 number routes to the nearest franchise for *them* to take the order. Which probably saves Pizza Hut Inc. some money and puts more onus back on the franchises. Not to mention that Pizza Hut -- like most franchise operations -- will likely transfer 2x the 310* cost to its franchisees.

I really don't see how Pizza Hut's system is any > different, other than the fact it's 10 years late. It's been a long time since you lived up here, I see! About five years after Pizza Pizza instituted their well known 967-1111 number they stopped using it as their "main" number. Why? Because their operations had spread beyond Toronto, into many small towns outside of the local calling area. They first tried to solve this problem by telling people to call long-distance, and they would reimburse them $0.50 for their phone call. This did not go over well (people just don't like the idea of long distance) so they tried an 800 number (short-lived). So, since then, they have just tried to set up vanity phone numbers in the smaller community that end in 1111 (eg. 542-1111 in Kingston, 697-1111 in Bowmanville, etc.) Their 967-1111 number was just a plain old Toronto number. Pizza Hut's new "PrimeLine" number is a lot different from Pizza Pizza ... a) The 310 exchange is a local seven digit call from ALL places in Ontario (with the exception of some FAR FAR North exchanges), and soon all places in Canada (hopefully); b) When you dial 310-1010, it will connect you to your LOCAL Pizza Hut, not a big dispatch which would resend your order to your local store (such as Pizza Pizza's old 967-1111 service used to do), and c) Depending on such things as your postal code, your exchange, and the time of day, it will forward to the appropriate Pizza Hut. This is so that if I want to order a pizza at 2am, and my local Pizza Hut is closed, it will connect me to the next nearest open one. (This would only have to be programmed once, not forwarded nightly). BTW, The jingle <967-11-11 phone Pizza Pizza, yeah-yeah-yeah> was so well-known in Toronto (and still is) that there were some stories about customs officials who would ask people who claimed to be from Toronto and forgot to bring sufficent ID to prove that they were, what the number for Pizza Pizza is. If they knew the phone number, they could get across. Now a part of Pizza Pizza's jingle is . Almost makes a case for the ownership of a phone number, eh?

It is used by the Dept of Telecom (DoT) for, among other things, charging an annual $80,000 'license fee' for e-mail providers, and $50,000 for BBSes. No BBSes have paid, of course. Paying a license fee gives you no advantages -- no better line conditions, no priority in routing or allocating new numbers, no discount in call charges. It just gives you a license to operate. I've been unable to locate a source for comparision with other countries. I'd info on how others handle these things, especially in developing/Asian countries. Here's how the DoT monopoly runs the show: In India (prices in US$, = 31.50 Rupees) 1. local call 0.03/5 mins 2. long-distance 0.50/min (delhi to bombay peak) 0.06/min (nowhere to backwater, midnight) 3. international 1.00/min (south Asia) 1.75/min (Europe, Arabia, SE-Asia) 2.10/min (America) 4. cellular local 0.30/min (for proposed private duopoly,big cities) Datacom: 5. leased line, intra-city 50/km p.a. long-distance 30 - 10 /km p.a., depending on distance (these are voice-quality lines, officially 9.6kbps, can often do 28.8) 6. 64kbps digital circuits 5,000 (50 kms) to 30,000 (900 kms) p.a. 7. 2mbps 50,000 (50kms) to 230,000 (1000 kms) p.a. (for 5-7, if you build your own network with switching, you pay 2.5 the amount, as DoT is terrified that you may use these 'private data networks' instead of its volume-based lines!) 8. I-NET (DoT X.25 net) 0.30 (local, off-peak) to 7.50 (international) per 32k data transmitted 9. ISDN n.a. (technically feasible, but not offered) Licensing: 10. BBSes max(50,000 p.a , 40 * subscribers) (nobody's paid) 11. e-mail max(80,000 p.a. , 50 * subscribers) (Sprint, BIIT, others have paid) 12. Internet (full-service) "not permitted" (ERNET is an academic network; NICNET is the government's own; both are connected to the Net. VSNL, the public sector monopoly on all international comms, is happy to grant connectivity to net providers, and even asked for franchisees last year, though the DoT (which presumably controls VSNL) claims such things are not permitted) Licenses do not provide benefits, only the right to operate. Data comms users get no advantages at all, leased line maintenance is poor, and indeed is charged for in addition (along with the 'conditioning' of long-distance analogue leased lines). DoT PR repeats that (local) call charges are among the lowest in the world, that it needs to charge more for 'premium' services to pay for connecting villages etc. However DoT's companies make huge profits, of about 35%, which are among the highest in the world. While such profits may be spent on wiring remote areas, money for such purposes is better generated openly from investors who are aware of the risks and share the profits, rather than unsuspecting consumers.

So you could have an AT&T subscriber with the -same- number as an RTI customer, and the person calling them would have to know which carrier code to prepend. Very confusing. This was kind-of addressed with the introduction of the "500" service access code, which, like more traditional numbers, did not depend on any carrier identification. (Well, for the moment the prefixes are specific to a carrier, but portability is supposed to be phased in just like with the earlier '800' SAC) However, I just discovered a potential problem. It's not the end of the world, but it caused me some difficulty. My personal phone line has -all- IEC, and most intra-lata long distance, service blocked (1). So to make such calls, I have a no-surcharge calling card with . I punch in the (free) 950-xxxx access number, my id, then the destination digits. Only problem previously was that, for fraud prevention reasons, one of the international destinations I would occassionally call was blocked. (No, not the sex lines. Well, they're blocked also ...) Now you may have noticed that our esteemed moderator recently got a '500' number. So I tried calling him. My carrier would -not- complete the call. On speaking to them they explained that since the call was "actually" going over an AT&T link, they had no provision to charge me for it and hand the money to their competitor. Kind of like the situation with '900' codes. Which suggests (and maybe someone with the calling card of another company can check on this) that unless you have an AT&T card, you -won't- be able to call 700 numbers from, for example, a coin phone. (Or, in the future, as the other companies put in their 700 numbers, you'll need their cards as well). Hopefully the different companies will, in fact, work out some mutual charge agreement. But for now the confusion is still there. *1: I wanted for years to get a restricted line with these blocks, but NY Tel told me it was either impossible or highly expensive. Then I fell behind on my phone bill payments and could only kick in enough to "maintain" local service. So they've blocked just about all calls outside my immediate calling area (all of NYC). And, for good measure, cut off access to the 'enhanced service' numbers as well.

How can it vary with the Bell > Atlantic Service Area ? > What is going on? Is my point two above completely wrong? In reverse order: (3) Yes, the FCC mandates the maximum allowable SLC, but LECs are not required to set their tariffed SLC at the maximum level. (2) Because the SLC is an FCC charge, whereas ISDN rates are primarily established by state PUCs/PCSs, a reduction in one will not automatically result in an increase of the other. The states are typically very careful to ensure that the FCC does not shift costs to the state jurisdiction. (1) Yes, I believe the SLC is assessed per channel on a digital loop carrier or other pair-gain system. The difference is that in pair- gain, the channels are provided to different customers. In ISDN, the chanels are all provided to the same customer. Although I've not followed BA's filing at the FCC, I assume the case they tried to make was that the SLC was intended to apply on a per wire-pair basis (it takes only one pair for a typical POTs line), and that since it takes only 2 pairs to derive 24 ISDN channels, the SLC should not be applied 24 times. Hope this helps.

It does a good job of explaining the concept of ISDN, its primary applications, and even has a (partial) list of vendors and equipment available. As for recommendations for terminal equipment, the best bet would be to check with a reputable equipment reseller or Pacific Bell authorized distributor. I believe it is important for any individual or company venturing into ISDN to work with a reseller with a reputation for providing technical support, and who is willing to act as a liaison with the local telephone company (Pacific Bell, in this case) AND long-distance carrier in the event of technical problems. It is not uncommon to have problems with missed installation dates, circuit problems (incorrect line provisioning, for example), and trunking problems. I have experienced a rash of trunking problems recently, mostly with MCI -- primarily due to incorrect routing of the data calls over voice trunks. This is a major aspect of what my company, Synapse, does in addition to selling ISDN equipment. Even with local telephone companies experienced with ISDN installations, such as Ameritech, these types of problems are frequent. It was amusing to read the recent article in Boardwatch Magazine (March 1995) describing the experiences of a hardly unsophisticated user with his residential ISDN installation. > What equipment is required at the customer's site?

Hahne) Subject: We Need a TDM; What Will Work For an Internet Provider? Date: 6 Mar 1995 14:29:09 -0600 Organization: UTexas Mail-to-News Gateway I'm no telco engineer, so hopefully somebody can give me a few pointers as to the right product(s) for this application. My guess is that I just need the right mux, but maybe I'm missing something. The goal is to bring in several sub-T1 leased connections, muxed over a single T1, and then break them out into separate lines again so that they can be fed into an Internet router such as a Cisco 7000 (or choose your favorite high-end IP router). Our site is at the hub as the (small but growing fast) Internet provider, and of course the sub-T1 connections are downstream sites such as businesses and organizations. Life gets a lot more interesting when you throw in the fact that we're in Japan. However, I don't believe that this changes the possible technical solutions; it's probably just going to limit the equipment that we're legally allowed to buy. The picture looks something like this: leased-line ---- ----- Cisco 7000 port customer \ / \ / \ fiber T1 NTT / leased-line ----- MUX1 -------------- DSU ---- TDM?? -------- Cisco 7000 port customer / to our site \ / \ / \ leased-line --- ----- Cisco 7000 port customer (Yes, T1 has to be pulled in over fiber in Japan). MUX1 is provided on our behalf by the phone company and is physically done at an NTT site. The DSU comes from NTT also. But what goes beyond the DSU is our problem. What I need information on is the "TDM??" piece above. It needs to be some sort of demux that goes from the DSU (which probably uses an RJ45 connector, and is definitely an I interface) to either V.35 connectors or RS449 connectors, since a Cisco understands V.35 and RS449. Any suggestions? There must be a canonical solution to this problem, right? More generally, is this the best way to pull in the multiple downstream clients, or is there a better method (perhaps an IP router that can split the T1 apart internally?) Feel free to bombard me with solutions, sales pitches, equipment lists, blatant advertising for telco gear, whatever. It's often tough to get information on IP and telco gear in Japan so I always welcome literature. If you're asking "why mess around with fractional T1; why doesn't everybody go for straight T1?", the answer is that Internet connections are so expensive here that only top-level providers can afford a T1. In fact, right now the _entire_ commercial Internet bandwidth coming into Japan is less than T1!

How does the network know where to deliver a piece of email? In fact, given the packet nature of all Internet traffic, how do telnet or ftp packets get, reliably and generally quickly, to their destination? Few even recognize the term DNS, the Domain Name Service, which handles the problem. Administrators may have used BIND, the Berkeley Internet Name Domain program, to manage DNS, but may not fully understand the importance, use or finer aspects of it. This book gives both background and operational details. Given the nature of the netowrk routing problem, a full understanding of DNS likely requires actual hands-on work. Albitz and Liu have, however, put together clear, straightforward, and sometimes even lighthearted text to make the learning process as painless as possible. copyright Robert M.

Covert Subject: GSM Rental in Germany I want to rent a GSM phone with a German number in Germany in about three weeks, but I can't find any rental companies. I'll be in Germany for about nine days. I travel to Germany every year about this time, and since 1989, I have been able to rent telephones, through Budget rent-a-car, through Lufthansa, and last year through a small company which was in the process of going out of business even as I was renting from them. My investigations so far have yielded nothing. Noone is willing to rent a phone. Budget no longer has portables; only phones built into the cars. Lufthansa is out of the rental business, as it seems everyone is. Too many problems with people running up horrendous international call bills and then disappearing. I want a German number. This may not be possible. I'm also investigating buying a phone and signing up for a whole year's service in the U.K., since I expect to be there for a few weeks this summer on a separate trip, but even that may not be a real possibility, since I don't have residency in the U.K. At least in the U.K. rentals are available.

Provided you have a mu to A converter in between you will only get e few dB of degraded S/N ratio. If you feed a mu-encoded signal into an A-law receiver (or thew other way) you _may_ get an intelligible result (yes, I have tried), but the S/N ratio is probably well below zero (I have not measured it). Remember, in A-law encoding every second bit is inverted. I think you have two options: 1) Disconnect the handset and measure it separately. 2) Check if it is possible to strap the PCM codec to make it work in mu-law (many circuits can do both). > can anyone tell me what the error would be in dB when I sweep from 300 > to 3400 Hz at a constant level, and do a loudness calculation?

PAT] I don't think the case has been resolved. I got sent some promotional literature about this military saver option. It costs $8.50 per month and you get something like 20% discount on your calls. BUT if you don't make any calls in a given month they credit the $8.50 back to your account the next month. This debiting-crediting cycle has happened three times now so they haven't discovered the mistake. It means that I'm always $8.50 out of pocket. Also the crediting and debiting are translated into UK$ using interantional exchange rates, and as the credit rate is different from the debit rate (the banks make a profit somewhere) then I get charged every time they do that trick (even though the credits and debits are make on the same day). I don't think the charges are particularly competitive with other services. There are services here that charge around 30c a minute to the US whereas AT&T charge you $2.50 before you've said anything (or something like that, I don't remember the exact terms). Anyway, my question still stands. Does AT&T Charge Card have an email address or even a fax number?

Cheers! dcbr@chevron.com (970) 675-3838 <-- New number after April. [TELECOM Digest Editor's Note: Can you believe they had the nerve to settle the 312/708/630 fiasco late last week by deciding that we in the northern suburbs will have to have *our* area code changed to 630 later this year. Chicago will retain 312 exclusively; the politicians and other hotshots would not hear otherwise. 708 will be almost directly straight west of Chicago in the western suburbs, with part of 708 in the southwestern suburbs moved into 815 (which for the most part is quite underused.) All we northerners have to move to 630. The few wireless customers already resident on 630 -- there maybe all of 500-1000 customers there, and that is it, period -- will be moved to the proper geographic code. So in other words, 630 will not be a wireless overlay, nor will it be co-resident with 708 as originally proposed on a first come, first served basis. Instead, 708 will be chopped in three parts. I wonder if there have been any other splits where part of a 'new' area code' (i.e. 708 in recent years) was given to an 'old' (i.e. 815, around since the beginning of area codes) rather than handed off to a newly created one? The cellular people gave Ameritech such a fuss about having all their stuff parked in 630, that they originally decided on the co-resident plan for 708 instead. Then when all the suburbanites made a stink about having their next door neighbor in a different area code, the decision was finally reached to do things in a more conventional manner. Forget ever expecting 312 to be inconvenienced in any way; Mayor Daley would never permit that.

The documentation says that if a DTMF tone is played while voice processing the modem will send a shielded result code to the DTE. I have been able to receive normal result codes such as "OK" when issuing an AT command but I don't understand how to receive a shielded result code while I'm receiving voice data. My second problem is that there I have been unable to find information on writing communications software using Visual Basic and the AT command set.

I have received a "Product Bulletin" from Northern Telecom, outlining some 14 "Design Changes" between DR5 and DR5.1 software. In my opinion, most (if not all) of the changes are to correct deficiencies in the existing DR5 software. For example, one change is called "End of conference Privacy Release lock-up." Sounds like a bug to me. Several other changes apply patches to areas known to allow a user to defeat the toll restriction in the Norstar. One vendor says there is no trade-in. We are faced with simply buying the new DR5.1 software package for the same price we paid for the original DR5 ($413.65), and chunking the DR5 in the trashcan. I'm not pleased with the prospect of spending over $4,000.00 for what I consider to be a "bug fix." Has anyone else received similar news? Better pricing? ------------------------------ From: roodh@dds.nl (Hendrik Rood) Subject: Re: Requesting Information About SDH Date: Mon, 06 Mar 95 02:47:28 GMT Organization: Hendriks Humble Home Hero In article , dehoog@st.rim.or.jp (John DeHoog) wrote: > In article , wgan@netcom.com (willy > gan) wrote: >> I'd often seen the words SDH or SDH compatible equipment >> advertised in data communication magazines.

Here in Japan, some major telecom > makers have developed SDH equipment based on the CTRON specifications. SDH is the international (ITU) version of the US (ANSI) SONET-standards. SDH starts at bitrates of 155 Mbit/s which compares to US SONET-OC3. The major differences between SONET and SDH for 155 Mbit/s and above lies in the overhead and network management features, also terminology in SONET and SDH differs slightly. SONET talks about Virtual Tributaries, SDH about Virtual Containers. Although incompatible it is expected in future systems that conversion between SDH and SONET is more a software issue than a hardware issue. But in the first hardware implementations this is still not the case, because manufacturers have implemented some functions in firmware in the interface-cards.

It actually talked about something other than porno and child molesters on the 'net. They actually did a reasonably good job talking about newsgroups, ftp'ing, telnet'ing, golpher, and such. They did a demo of newsgroup reading, think it was this very group, and they demo'ed how to post. They responded to a question about how many long distance lines crossed the USA (he said he was sure the number was 42).
