PAT] Because, there are many computer systems out there that are for free public access by anyone who wants to dial the number and poke around. When I get onto a system, how do I know whether or not I'm 'supposed' to be there? How do I know whether this system is some private company's mainframe, or some guy's PC in his garage? If the system tells me, right up front, 'for authorized personnel only', then if I don't KNOW that I'm authorized, I'm not supposed to be there. If it says 'Welcome! Glad you're here! Good Day!', I get the idea that I'm welcome. If some Dutch hacker stumbles into a private computer system and it welcomes him gleefully, I don't think it's unreasonable for him to believe that he's welcome. Now, if he does malicious harm to that system, that's another matter ... J.Baker enuucp!gtephx!bakerj [Moderator's Note: How do you know if you are welcome or not?

These guys need to know that it is not nice to fool around with other people's computers. But I wonder if the prosecutors really think some of these things through. Specifically, the matter of punishment should be examined. Throw these guys in prison and you will turn the place of their incarceration into "Hacker U". Everything they know will be passed on to some REALLY bad guys who will use this new knowledge to best (worst?) advantage. Fines are not a bad idea, and community service would also be appropriate. But I am not too sure that I am very keen about having real crooks find out how to "get into the system" the easy way. Of course, if security is beefed up in the mean time, fine. But then, that would be a "burden" upon innocent parties, right? Hope they enjoy it when the graduates of "Hacker U" start in on their weenie security. It is not about who is right or wrong (I concede the hackers were "wrong", but so what?), but about what it takes to keep people out. Punishing hackers does not keep the real baddies out of insecure systems. Put hackers away if it makes you feel better. I am certainly not here to justify their actions.

Mike Godwin and others at the EFF have stated over and over that they don't support computer crime or criminals. Their purpose is different. Remember your story about the Chicago police that used to use a crank-telephone to interrogate suspects? Electrocuting suspects isn't the right way to fight crime. A reasonable person can be against zapping alleged criminals, and at the same time deplore the criminals' purse snatching. I detest the arrogance of juvenile (and not-so-juvenile) delinquent network crackers. Here at work for the last week we've been running a password checking program on all our accounts because we heard it was being run "for us" in Australia and Sweden. I have better things to spend my time on, like making the user environment better for our users. Instead I burn cycles on a hundred processors for a week. On the other hand, Mitch Kapor's advocacy of universal ISDN access and open national network access is, IMHO, a good thing. If they want to push for clearly defined legal protections for computer communications, that's good too. Even providing amicus curiae briefs to ongoing trial to avoid bad precedent is good.

But ... well ... which of these are you saying ISN'T evil? The government? Are we talking about the same government that's used an inverse neutron bomb on the Bill of Rights; leaving the people behind but burning down the entire structure? The same government that helped defense contractor Kerr-McGee hide behind official secrecy while poisoning its workers (and possibly murdering Karen Silkwood), and then turned around and did the same thing when GE's defense nuclear projects were dumping radioactive material into groundwater? Not to mention MK-ULTRA, the LaPenca bombing, the CIA drug connection, the unlawful imprisonment of Leonard Peltier, the harrassment of CISPES, and looking the other way after (and possibly having been involved in) the attempted assasination of Judy Barry. Or the attempted assassinations of foreign leaders Fidel Castro and Mohamar Khaddafy? And have you already forgotten the murder/coverup of Daniel Castolaro? The credit bureaus? The same people who've been using dubious means to accumulate dossiers on everybody in North America, and fighting hard to keep from having to admit that AT LEAST one third of those dossiers are so error-prone as to be worthless? And who, according to former insiders, collect an awful lot of non-credit-related information? And who fight you tooth and nail when you try to get a correction? And after the endless messages over the past month about GTE, PacBell, and so on, I should think it looked like we were all in agreement that the telcos are no blushing virgins, what with "slamming," arrogant billing practices, deliberate misdirection of state PUCs, abuse of monopoly priviliges, and cooperation in the 800-to-900 scams. So even if I thought that all hacking were wrong, I admit, the part of me that likes to see David slay Goliath, and that hates Big Brother and anybody who tries to set themselves up as a predator on the people, would inwardly cheer to hear about anarcho-hackers taking on the evils in government, credit bureaus, and telcos. And nobody would be happier than me if some hacker got into and out of a system with more proof of these crimes. I guess that makes me "socially responsible."

That isn't as easy as it might sound. First of all, I speak only enough Spanish to get my face slapped. Secondly, though we have the ANI -- and even the apartment number and street address on West 133rd Street -- and even the subscriber's name. That is not sufficient proof that the subscriber or any resident of apartment 36 is the culprit. It only means that _someone_ is using "Pedro's" telephone line. As the telephone circuits in apartment complexes in major cities "appear" in various distribution boxes (cans) anyone with a bare working knowledge of telephones can "tap into" Pedro's line at any one of several locations and practice their deeds with complete anonymity. It's like a game between the fox and the hound. Beyond this, I am not at liberty to go into any more detail at this time. As I said in my original post, the hackling is calling a _great deal_ of attention to himself by his continuing actions. [Moderator's Note: Although you have no proof that Pedro is making the calls, I don't think it would be out of place for you to call the number and give them a little pep-rally. Several years ago when my wallet was picked out of my pocket riding the subway (I caught one and almost did a "Goetz" on him; the one with my wallet got away) I lost an IBT calling card in the process. I stopped it the same day, but when the bill came the next month and I saw a residence number on there as the origin of one fraud call I rang them up gave them a piece of my mind, telling him I ought to pollute the number so badly they could never use it again, fraud calls or otherwise. :) PAT] ------------------------------ Date: Thu, 9 Jul 92 12:16 PDT From: john@zygot.ati.com (John Higdon) Reply-To: John Higdon Organization: Green Hills and Cows Subject: Teleslime (A Tip) If you happen to know who the telemarketer is and it is within your LATA, here is a method you might try for retaliation. Most readers of this forum are well aware of my year-long bout with the {San Jose Mercury News}. The many lines of my home would be assaulted regularly by callers wanting to know if I was "receiving the paper OK". This, of course, was the foot-in-the-door line that would determine if you were a subscriber (they did not have subscription lists in front of them). After getting these calls on private lines several times a week I started taking action. I talked to the head of telemarketing at the SJMN. I talked to the president of the telemarketing contractor. I was assured that the calls would stop after they entered all of my numbers in their reject database. The calls continued. The SJMN blamed the contractor. The contractor blamed the dialer software company. The calls continued. I had my attorney write threatening letters to both the SJMN and the telemarketing company. The calls continued. Finally, in desperation, I called Pacific Bell and reported the problem as "harassment calls". I explained that I had repeatedly asked the SJMN to stop calling me and that my requests were ignored. The usage of my telephone was, in my opinion, being compromised by such continued disturbance. Bingo! The next day, the telemarketing president called and sounded very crestfallen. "I guess you called the telephone company?" "Uh-huh" "I really wish you hadn't done that." "And just what would you have done in my position?" The long and the short of it is that I have not had one single call since that time. Through other sources I learned that the telemarketer immediately removed the entire prefix from the machine to ENSURE that I would not be called again. (Why could that not have been done in the first place???) I can only guess, but it appears that the telco wields a very big stick (like maybe disconnection of service?) when it comes to telemarketers. If I find any of these types offensive and find that they are local, you can bet another call will be made to Pac*Bell. This may work in other areas as well. Footnote: In the past month, I have changed every single phone number in the house to another prefix. So far, no calls from the SJMN. We shall see. John Higdon | P. O.

It's invasive. I use a Caller-ID product that permits me to add a name to the phone number sent by the Telco. Further, this permits me to automatically terminate the calls I preselect as telemarketers or whoever I don't wish to communicate. I can have this change as a function of day of week and time of day. Further, I can group callers into ten groups and have them managed according to day/time as well. There is the ability to have a screen of notes, automatic or manual switch to an answering machine, records of all inbound and outbound calls and a host of other features. I have been using it for over a year now and find it very useful. It is a DOS machine board that takes up one slot and can be run as a TSR or as a dedicated machine.

The indictments name Mark Abene (Phiber Optick), Julio Fernandez (Outlaw), John Lee (Corrupt), Elias Ladopoulos (Acid Phreak), and Paul Stria (Scorpion). The indictments charge that the accused used their computers to access credit bureaus, other computer systems, and make free long-distance calls. Prosecutors revealed they relied on court-approved wiretaps to obtain much of the evidence for their multiple-count indictment for wire fraud, illegal wiretapping and conspiracy. Each count is punishable by up to 5 years in prison. The defendants are scheduled to be arraigned in Manhattan Federal Court on July 16. If found guilty on all counts the defendants could face a maximum term of 50 years in prison and fines of $2.5 million. Otto Obermaier, U.S. Attorney, discounted suggestions that the acts alleged in the indictment were only "pranks" and asserted that they represented "the crime of the future." He also stated that one purpose of the indictment was to send a message that "this kind of conduct will not be tolerated." Mark Abene, known to the computer community as Phiber Optick, denied any wrongdoing. The Electronic Frontier Foundation's staff counsel in Cambridge, Mike Godwin is carefully reviewing the indictments. Mitchell Kapor, EFF President, stated today that: "EFF's position on unauthorized access to computer systems is, and has always been, that it is wrong." "Nevertheless," Kapor continued, "we have on previous occasions discovered that allegations contained in Federal indictments can also be wrong, and that civil liberties can be easily infringed in the information age. Because of this, we will be examining this case closely to establish the facts."

PAT] For some reason, Pat's respect for the rights of others stops short of our right not to be libelled or deliberately misrepresented. Specifically, Pat believes that it is appropriate to invent and disseminate vicious misrepresentations about EFF. The public record, however, puts the lie to Townson's assertions For example, Mitch Kapor wrote in the September 1991 issue of EFFector: "The Electronic Frontier Foundation has never condoned the unauthorized entry into computer systems for any reason. There is absolutely no question that uninvited computer intrusions represent a major problem on the electronic frontier; and one which we, and thousands of others, struggle with on a daily basis." But perhaps Townson missed that issue. Did he also miss the very first issue of EFFector, in which Kapor wrote the following comment? "I regard unauthorized entry into computer systems as wrong and deserving of punishment." This was published in March 1991 on paper; it appeared online in late 1990. Is Townson so interested in promoting a view of himself as anti-hacker that he does not care who he defames in the process? EFF has worked on occasion to prevent innocent people from being punished, and to see that government prosecution of the guilty is done in a way that does not compromise the rights of all of us to due process. We are proud of this work. But only someone whose disregard for the truth borders on the pathological could suppose that we *ever* seek to excuse unauthorized access, or that we routinely defend those who engage in such acts. I think there is immense irony in Townson's claim that we're expected to utter "shrill chatter" as we "defend the darlings" (whoever they are). I doubt anyone at EFF is capable of being as shrill as Townson. And I am certain that we have higher regard for the truth than he does.

I'm sure that they already do this, but you may want to verify that they generate reports based on commonality of all locations that fraudulent cards were recently used from. After all, for every valid call, they have a record of the ANI of the calling number. It should not be too hard for their computer to figure out that a large number of calling cards that were used at that specific hotel had fraudulent charges occur shortly thereafter.

The solution is an intelligent call access device that can hear a series of coded tones coming from a verification point, and respond with the appropriate reply tones. The tones first sent would simply be a random sequence. The verification computer AND the intelligent access device would both perform a one-way encryption of that random value. The device would send it and the verification computer would validated it against what it figured out. The key to the encryption would be one assigned only to you so the verification computer would have to already know who you are (at least claiming to be). > More specifically, does anyone have suggestions for what I can or > should do about this situation?

There is the distinct possibility that the hotel did not play any part in this theft. It really should be AT&T's concern at this point. What I suggest you might do is buy some stock in AT&T and proceed to complain through the channels as a stockholder that AT&T needs to take stronger action against this "profit lossage". There will be the argument that the cost to enforce is higher than the loss (and it might be true, at least today). But the problem won't go away unless something is done about it.

(1) Use the card-reader phones, where you "swipe" (no pun intended) the card or insert it momentarily into a slot, and; (2) Press the numbers in on a touch-tone phone, but cover my dialing finger with my other hand so that only I can see it. I am REAL aware of the people around me and will notice if someone tries to look in, in spite of my covering up the touch tone pad. I have been aware of the potential for SMDR-based calling card fraud at hotels and motels ever since 1985 when I made an AT&T calling card call from a motel room. When I checked out, I was offered a copy of the SMDR printout, detailing ALL of my calls. I was somewhat surprised to see that my calling card number and pin were captured on paper (and possibly elsewhere), along with the rest of the information on the calls. I was less telecom-savvy then, but I still realized the implications if a hotel employee (or dumpster diver, for that matter) were to get that information and exploit it for fraudulent purposes. If there is any way possible to conveniently do so, I use one of the two methods above to make calling card calls. The first method is preferable to me. I make it a point to cover the numbers on the card with my hand when I'm swiping or inserting it. I also try to use a phone where there isn't someone nearby who can even observe what I am doing, be it dialing in a number or swiping a card through.

The 950 number gives the caller access to the LD "company", but the caller still has to enter his/her calling card number. e.g. MCI's 950 number is 950-1022, and is a local telephone number in most areas. If it's not available, there's always 800-950-1022. jc ------------------------------ Subject: Re: Roommates and Long Distance Doesn't Mix From: art@aficom.ocunix.on.ca (Art Hunter) Reply-To: art@aficom.ocunix.on.ca (Art Hunter) Date: Wed, 8 Jul 1992 07:10:01 -0400 Organization: AFI Communications - Ottawa, Ontario, Canada > One possibility is to get a toll restriction device.

You are certainly correct about this, but why couldn't they have requested a new special service code for this type of service, something like 500 or 600. They didn't have to use 700.

It would be nice if there was a way for the caller to select voice, fax, data, or whatever new gizmo I am attaching. Thus if someone is calling me from their "fax subchannel" it would ordinarily and automatically be directed into my "fax subchannel" even though they are using the same exact number to reach me as if they were using voice. It would also be nice if one could have multiple incoming and outgoing lines, that only take up ONE number slot as far as ordinary dialability goes (some specialized access dialing could address individual lines for diagnostic purposes).

PAT] ^^^^^^^^^^^^^^^^^ Yes, EasyReach calls can be placed {10288} 0 + 700, 1 + 800 followed by {0+}700 (using the 800 access method), 10288-0 or 00- ("real" operator assisted). I would hesitate to use the words "operator assisted" in reference to the 0 + 700 dialing however. No operator will ever come on the line when an ER700 call is dialed {10288} 0 + 700. "Operator Assisted" usually implies surcharges and these surcharges are not part of the ER700 tariff for 0 + 700 dialing (unless of course you bill to a calling card or call the operator). In effect, a 0 + 700 call is billed like a 1+ call and at similar rates. John Butz Easy Reach 700 System Engineering AT&T Bell Labs jbutz@homxa.att.com [Moderator's Note: It is not billed 'at similar rates' ... Easy Reach calls are much more expensive per minute. Also, 'operator assisted' has come to mean any call other than 1+, IMHO. Perhaps a better way to phrase it would have been 'special handling/billing'.

I used to have an account with Mid Atlantic Telecom here in Washington, DC. Every month I got the bill for an 'overlay' 800 number that was attached to the ordinary local telephone number as the equivalent of a second phone number attached to it. I also had an 800 number for a voice mail account I was using at that time. At the end of each month I would get the bill of the flat-rate service charge and the bill for the amount of charges for calls received. On a separate page they sent me a list of the time, date, length of call and the telephone number calling from, for every call made to each of the 800 numbers. A while back, a company selling equipment to cable companies was selling a system to allow the called party to get the ANI of a caller, from MCI's 800 network, in real time, usually for ordering pay-per-view services. You called it and it does what the Atlanta number from the 732 network that I reported earlier does: it reads back to you the number you are calling from. They got so many calls they had to stop the demonstration. I think C&P Telephone company is trying also to cash in on this by using something similar. In the latest telephone directory, a local exchange is marked "Pay Per View." And the intent, I would assume, is to allow someone to call a PPV number and using caller-id, it could do the same thing as the 800 number; more importantly, since it's a local number, the cable company would not be metered at 16c a minute for calls coming into it; they could conceivably use the service for different orders, if the service was cheap enough. At least one local cable company in the area is using this exchange for this purpose, a user on a local BBS informed me.

When they first introduced the system, they took two pages (pages 2 and 3) of their catalog to explain their policy for using Caller-ID. I can understand why few people ask them to disable it.

Does anyone out there know if local exchanges keep any kind of call detail records? Specifically, I'm interested to know if a law-enforcement agency would be able to obtain a record of all local calls made to a specific number for some period in the past, without having requested a trace in advance. My house has been robbed twice in the last six weeks, and I suspect the culprits have called in advance to make sure I wasn't home. There have been a few times recently when I have been home when I'm normally at work, and the phone would ring. When I answered, the caller would hang up. This rarely happens at times when I'm "supposed" to be home. I think someone knows my schedule fairly well, but calls just to be sure. I'm going to run this idea past the local sheriff, but these guys aren't too swift about stuff like that. Maybe sometime I'll entertain you folks with the story of my parents' tenant who suffered obscene, threatening phone calls, as well as repeated break-ins, and the local constabulary's incompetent efforts at catching the perpetrator. Anyway, I thought if anybody out there could tell me if this is possible, I could be a little more insistent about it. I don't know exactly what kind of switch I'm on. It's fairly new, was installed about 18 months ago, with much hype about how great it would be. The company is South Central Bell, and the exchange is 606-987, if that helps any. [Moderator's Note: Yes, the new switches do keep very detailed calling records. Getting them examined may be a hassle, but they do exist. Now of course if you had that nasty old Caller-ID, or even 'return last call', you could invade the caller's privacy by noting the calling number and act on it from that direction. Not only do hackerphreaks not care for Caller-ID, I suppose most burglars who call ahead to scope things out don't like it very well either.

It sounded like this: "Sssssssssssssss...."

(Since they hang up after reporting the time, it was impractical for him to determine the exact moment of switchover.) This suggests that PacBell adjusts their time-of-day clock manually rather than relying on an automated system linked to WWV. And it brings up more general questions: How accurate is the time-of-day reported by PacBell, GTE, etc.? What incentives do the telcos have to report time-of-day accurately? I can think of a _disincentive_: the service is free, and the more accurate it is, the more it'll be used. Surely accurate timekeeping is important within the telco switches for performance and accounting reasons.

They would like to develop a program which can answer calls placed to these extensions and use speech recognition to find a phone number when given a (spoken) name. The main problem is how to do the phone line handling and A/D and D/A conversion. My vision of the ideal solution would be a VMEbus board with 8 or so RJ-11 jacks on the front. The board would be able to answer and hangup the phone and also digitize incoming audio and DMA it into memory, it would also need to be able to output audio from digital data in memory. Does anyone know of a board like this? Can anyone give some suggestions on they might approach this problem? I would be very interested in talking to someone who knows about this sort of thing.

All the lights and such don't work because they want some voltage from a PBX or something, but all 20 lines work nicely. Because it's a PBX phone, however, the volume out of the handset is pretty low. I'm also told that the volume from the mic is low. Interestingly, when another extension in the house is picked up, I'm told the volume on the other end improves. Can anyone explain this? And can any suggest a simple circuit (preferably passive, or using phone power) to boost volume to the earpiece?

I got this number off of the RIME BBS Network "Phones" conference. I have tried it and it works, even from a U.S. Government Centrex number. I do not know if there is a charge for the call, as I do not remember seeing it on my phone bill. The exact number to dial is: 10732-1-404-988-9664 Note this is a special number using the 732 network, a private network operated by AT&T. After a tone, it reads back the area code and phone number placing the call, then what apparently is a checksum digit. At this point it no longer has the ANI information and then reads back all zeros. If AT&T is charging for this; all well and good, they are not likely to drop it; if not, please be prudent in using it so as not to see it cancelled.

The other lines are the old fashioned kind that go directly into the house, with the protector block mounted in my basement. I assume that the protector block is now part of the network interface. What I don't understand is that there is no ground wire going in to the network interface box. All my other protector blocks require a ground for proper operation. There are two screw holes on the "customer" side of the box marked "G," but these are just holes and don't have any conductors (or screws) in them. There is no other obvious place to put a ground wire. Should I connect up a ground wire somehow? To what? Should I install my own "old-fashioned" protector block in the basement? The network interface is a Keptel SNI 4600 and the line is basic rate ISDN, if that makes a difference. ------------------------------ From: leavens@mizar.usc.edu (Justin Leavens) Subject: The Message Center Offers 'Daily Reporter' Service Date: 11 Jul 1992 10:24:50 -0700 Organization: University of Southern California, Los Angeles, CA As a recent subscriber to Pacific Bell's Message Center, I was offerred a free month of their new 'Daily Reporter' service. Essentially, the service drops you a piece of voicemail every day from Dow Jones giving you a little blurb on whichever of the topics you subscribe to (now offerring News, Sports, and Financial categories). The messages are not cumulative, so yesterday's news is replaced by today's news. Each topic is $0.75 monthly, $1.50 for two, and $2.00 for all three. This is supposed to be an inital test of the system, with future additions to the topics: weather reports, restaurant and movie reviews, "and even a daily horoscope!" [oh boy]. To quote more: "You'll also be able to receive information customized to your needs. For example, you'll be able to select only the sports teams you want to know about, or choose spcific financial reports on the companies you're most interested in." We'll see how this works. Considering Pacific Bell somehow 'lost' my original order for the Message Center in the first place, and the problems of the Message Center last year, I'm skeptical. But the operator I spoke with told me that they were planning on expanding the functionality of the Message Center in the next few months (that service to be available for 3X the price of current service) which would include features that GTE currently offers in it's voicemail service. Imagine that, GTE actually _ahead_ of Pacific Bell!

Under terms of the agreement, signed in Sydney, Australia on June 22, 1992, Digital will serve as the prime contractor to Optus to develop an Operational Support System (OSS) for what will be the world's first fully digital telecommunications network. OSS includes the network operating systems and applications software required to manage the many elements of a digital telecommunications network. Building Australia's Second Telecommunications Network Optus, which secured the right to operate Australia's second telecommunications network in November 1991, is a consortium of Bell South, Cable and Wireless, and several Australian firms. Plans call for digital cellular facilities to cover 80 percent of the population, with fibre transmission facilities built to cover most major centers by 1997. This will provide virtually all of Australia with access to Optus' services. Under terms of this contract, Digital will be responsible for the systems integration, management, training, and operation of the entire information technology needs of Optus, and, in effect, become the information technology arm of Optus. Other strategic contractors involved with Digital are: * NorTel Australia Proprietary Limited (for the switching equipment) * Fujitsu Australia Limited (for the transmission equipment) * Nokia Telecommunications (for the digital mobile systems) * Leighton Contractors Proprietary Limited (for the building construction) Optus Chief Executive Officer, Bob Mansfield, described the agreement as one of the largest contracts in the world for development of a fully integrated OSS. "This agreement will see the establishment by Digital of a global OSS Support and Development Center in Australia," Mansfield said. "Digital will also commit its international marketing resources to develop an export market for OSS with the potential to earn up to $1 billion (AUS) for new Australia-developed technology over the next decade," he added. Mansfield also noted that Digital had won its position by solutions and a business plan which will provide world class service and long-term export growth for Australia to other carriers and private network operators. Frank Wroe, Digital-Australia Chairman, said that the agreement with Optus "is a highly significant challenge to Digital. We are involved with every major telecommunications provider in the world, but Australia will move quickly to become a leader in fully- integrated open systems, using fibre technology in end-to-end digital networking." Russ Gullotti, worldwide Vice President of Digital Services, noted that "this agreement with Optus is the largest single systems integration and services contract we have signed anywhere in the world, and we are excited by the challenges and opportunities it will provide in the global telecommunications arena." OSS Potential For Export OSS will allow Optus to provide superior customer service, and a software product for export. It will also be the first fully integrated OSS. Previous projects attempted to integrate a mix of mechanical, analog, and digital technologies that existed in established networks. Digital will be the principal marketer of the new systems through its global operations, and is examining joint venture opportunities with Optus. Digital Equipment Corporation, headquartered in Maynard, Massachusetts, is the leading worldwide supplier of networked computer systems, software and services. Digital pioneered and leads the industry in interactive, distributed and multivendor computing. Digital and its partners deliver the power to use the best integrated solutions - from desktop to data center - in open information environments. #### DECnews is sent as a courtesy to members of the press.

A message today informed users that messages from June 23 to July 8 had been lost, but message receieved between June 28 and July 8th were being restored "and should begin to be recieved in your mailbox again soon." Messages receieved between June 23 and June 27th are apparently gone for good. Callers who reached the Message Center yesterday during the outage time between 1:15pm and 6:30pm were told that the Message Center was "experiencing difficulties" and were not able to leave messages. All Message Center users, according to the recording, will receive a credit for a month's free service in an "upcoming" phone bill. Anyone know the scoop on this outage? Luckily (depending on how you look at it) I just got my Message Center service and didn't set up my mailbox until last night, so I didn't lose anything.

Because their cordless phones are incompatible with THEIR OWN answering machines. The 5000 series of phones puts out tones in 80 millisecond bursts, no matter how long you depress the key. This is too short to trigger many of the remote features in their currently-market, top-of-the-home-use-line 1323 answering machine, as one of AT&Ts technicians admitted. (I believe the specs require a 750 millisecond tone.) Wait. It gets better. The entire 5000 series of phones puts out burst tones, so AT&T couldn't even specify another one of their models that IS compatible with their answering machines!

It turns out those calls should have been billed to ABC-9909, which was off-campus. For all I know, this could have been before stricter rules were put in for third-party billing. Anyway, I heard what had caused the confusion: People commonly said "...two nines oh nine" when referring to ABC-9909, and ABC-2909 was of course referred to as "two nine oh nine". ------------------------------ End of TELECOM Digest V12 #555 ****************************** ^A^A^A^A ^A^A^A^A Received: from delta.eecs.nwu.edu by mintaka.lcs.mit.edu id aa09319; 13 Jul 92 0:18 EDT Received: by delta.eecs.nwu.edu id AA08592 (5.65c/IDA-1.4.4 for telecomlist-outbound); Sun, 12 Jul 1992 22:22:27 -0500 Received: by delta.eecs.nwu.edu id AA07106 (5.65c/IDA-1.4.4 for telecomlist); Sun, 12 Jul 1992 22:06:26 -0500 Date: Sun, 12 Jul 1992 22:06:26 -0500 From: TELECOM Moderator Message-Id: <199207130306.AA07106@delta.eecs.nwu.edu> To: telecom@delta.eecs.nwu.edu Subject: TELECOM Digest V12 #556 TELECOM Digest Sun, 12 Jul 92 21:29:56 CDT Volume 12 : Issue 556 Index To This Issue: Moderator: Patrick A.

I really get mad, however, when the person on the other end won't termiate the call -- then all bets are off and I show no mercy. Phone telemarketers are not the functional equivalent of people who leave advertising slips in my door. The latter do little to impair the intended function of my door for me to enter and exit, and to admit my intended guests. Telemarketing prevents me from using my phone completely during the call. Telemarketers are more like fuller brush sales people that tie up my door. Like the former, like the latter always see to come calling when I'm the shower! :-) One thing that disturbs me greatly is receiving unsolicited fax calls on my home phone. These universally occur between 11:30 PM and 5:30 AM ET. I am obliged to get out of bed and answer the phone because I am on call for systems support at work. I have no practical means of fighting back to this particularly pathological form of telemarketing. I have a suspicion that I receive the fax calls because I meet a demographic model for a person who is likely to have a fax machine, but apparently the model is not smart enough to differentiate between a home and office telephone. I've been surprised that I've never received any sort of telemarketing attempts on my cellular telephone. It would seem that cellular users would be a juicy techie market and cellular exchange prefixes aren't terribly secret. It must be that success rate for telemarketers isn't very high when potential customers have to pay 40 cents per minute to listen to advertising. What would be nice to implement for caller ID is the ability to have the telco screen incoming from "unknown" numbers. Any friend or repair person would unlikely be calling from a station with unknown number enabled. I'd love sales droids to get a telco intercept recording informing them that, "your party does not accept calls from unknown numbers; this is a recording 2-1-6-1-7." This would speed up life for both the telemarket employee and myself. We'd both benefit. The employee would not have to listen to me being annoyed at her/his untimely interruption (good for the psyche) and I would have have to be interrupted. I disagree with Pat re: caller ID. Yep, I'd love to have it. Of course, I've called the local BOC to plead to have caller ID. The hard truth is that I still don't have Caller ID. There isn't any prohibition on telelmarketing companies from pestering me until such time as I may have Caller ID.

The first thing I would do is integrate Caller ID into my computer system, and have the system interpret the phone number against a database, and announce via its voice subsystem who is calling over my residential PA system. In our area, businesses and residential lines have different prefixes So, I can tell by the prefix whether I am receiving a call from a business line or another residential line. If my system doesn't recognize the phone number from its database, it can simply announce "incoming call from business exchange xxx-xxxx". I would be less likely to get up and answer the phone, only to have AT&T on the other end attempting to convince me to "switch back"... Dr. Michael P. Deignan (deg.pend.)

I do not need to make such a request. If you call and do not make a selection, the machine simply unceremoniously hangs up on you and I would never know you were there.

This is a perfect example of the "science" used by the product scare crowd. As anyone with the most rudimentary knowledge of modern technology knows, the point of a laser is to concentrate a highly coherent beam of light energy at a target. The "footprint" of a laser beam is literally millions of times smaller than that which results from 800 MHz RF originating from a handheld antenna. The name of the game is "w/cm^2". In the case of the .5 watt laser, we could be talking about thousands of watts per square centimeter. If we take that same .5 watt and apply it to an area of about 100 centimeters (conservatively the area covered on the body by cellular RF), then we are talking about 1/200 watt per square centimeter. Mr. Masterson's example is several orders of magnitude off from the discussion and not relavent in any way to the topic. Again, we are plagued by the "new voodoo": scare mongers who attempt to frighten the ignorant masses bringing up every conceivable psuedo-scientific ill that modern inventions supposedly cause. Most of the scare disolves away with even the slightest investigation and reality check. The real harm here is that all the "wolf crying" numbs many, including myself, to those few possibly real dangers. Unfortunately, our law and rule makers rarely aquaint themselves with the facts, so we get some very silly restrictions. Even the people of California enacted Proposition 65, which requires warning signs and labels on just about everything. It set up a whole governmental department (pretty lavish in a state that is currently without a budget!) that does nothing but enforce the placement of these silly signs. Has our quality of life improved from this law? Get real! What it has done is cause many such as myself to now virtually ignore all warning labels and signs. This is not good. A good rule of thumb is: check everything out from using established, recognized sources. And avoid organizations that have names in the format of "_________ For a Responsible _________" (e. g. "Union of Concerned Scientests", etc.). These are political action organizations who "use" science any way they see fit to achieve certain POLITICAL ends. Let us keep science and politics separate.

That is one four-hundredth of a centimeter times .008 or 3.2 watts per centimeter^2 or about 640 times the amount of RF concentration caused by a cellular phone. But you changed laser powers on me. I was using a .5 watt laser for my original figures and you substituted a much less powerful unit in your rebuttal. In any even, it still comes out to a comfortable order of magnitude difference.

I couldn't complete an AT&T calling card call to a number in Missouri from a LEC's pay phone at a service plaza on I-80 in Indiana (ITC was grabbing the 0+ and 1+ calls). After a few unsuccessful tries with "102880 ...," I called the AT&T operator and asked for assistance. When SHE couldn't get through she called what sounded like a marketing person, who explained that I could not place a 0+ call to that area code because the LEC had not made arrangements for handling calls to that area and that there was nothing they could do. I guess some parts of the country are not as important as others, as far as AT&T's potential calling card business is concerned. (I finally completed the call using MCI with MCI's ENFIA access.)

Unfortunately, there is a good reason for this proposed offering: information services. In order to deliver some of the things Pac*Bell has in store, ISDN will of necessity be installed at subscriber locations (including residences). To keep up the sham of "competition", Pac*Bell cannot arbitrarily install ISDN for itself and its products; it must do so under a definitive tariff. This is the very thing that Mitch Kapor and I have had e-mail disagreements about. His view (as I have come to understand it) is that information services from the RBOCs are a Good Thing because they will hasten the availability of ISDN for the common man. As far as that goes, he is right on. My concern has always been that the tricky telcos will tariff the ISDN in such a way as to make it virtually useless for any purpose other than the delivery of telco-provided services.

PAT] At PAT's suggestion a few months ago, I found that my 5ESS switch had "call return" and I've used it with great success in telling a little twerp off when she called at 3 AM one day. This incident occurred about two months prior to NYTel made their public announcement about this feature and "repeat dialing". Trap and trace are available but not announced as yet. I'm now waiting for NYTel to announce Caller-ID which is supposed to be available in August.

You are probably out of luck for several reasons. The level of detail on calls is "settable" by the telco. If the purpose is to bill count and duration of local calls FROM a telephone (telcos do not keep any kind of records concerning calls TO a telephone), then a "peg count" is used and carries little detail. In the case of unmeasured service, the telco typically keeps no local records at all. I know Pac*Bell does not (although some telcos evidently do when they go after the customer for "excessive" use). For local calls, unless you have "Call Trace" in your area, prior arrangements must be made to trap a calling number to your phone. And remember, even if such detailed records were kept, those records are designed for billing purposes and show calls made FROM a telephone. Every telephone subscriber's records would have to be scanned for YOUR number's appearance. The last time we heard about this was the famous Cincinati Bell case. > Anyway, I thought if anybody out there could tell me if this is > possible, I could be a little more insistent about it. I don't know > exactly what kind of switch I'm on. It doesn't matter what switch you are on. I can guarantee you that no records are kept of calling numbers to your telephone.

In his case, no they don't. It would be grand and glorious to believe that telco keeps indefinitely all records of every single connection transaction that goes on in every switch (including CALLING numbers), but such is fantasy. Telcos record those transactions necessary to bill customers and gauge traffic flow and nothing more. > Now of course if you had that nasty old Caller-ID, or even 'return > last call', you could invade the caller's privacy by noting the > calling number and act on it from that direction. As a proponent of Caller ID, you weaken your case by suggesting that all the records necessary to solve any harassment or criminal matter already exist within the phone company. The fact is, they do not. Hence, your suggestion for Caller ID, etc., is valid. In this case, however, the service "Call Trace" would be most desirable since we are looking for evidence in a serious criminal matter. Call Trace data would be far superior to the hearsay reporting of a number on a CNID display. John Higdon | P. O. Box 7648 | +1 408 264 4115 john@zygot.ati.com | San Jose, CA 95150 | M o o !

I think I know one of the reasons. Have you ever tried to call the police without using 911? I wanted to call them to report a road hazard (someone had been placing shopping carts in the street at night). I looked in the phonebook and got the number. I called it, and there was an answering machine. The message on the answering machine described various departments, and gave their numbers. You have to determine which you want, hang up, and then call that department. Of course, I didn't have a pen and paper handy, and from the message it was not clear which number I needed to call. Next time, I'm going to use 911, emergency or not. It wouldn't surprise me if many of the 911 non-emergency calls are from people who couldn't figure out what other number to call. Tim Smith [Moderator's Note: In the case of the Chicago Police, despite the fact that the Emergency Communications Center, the CPD Public Relations Department, the telco and others say that 911 should *only* be used in the event of a dire emergency requiring immediate police intervention (a stolen car is not an emergency; it already happened), when you call the district stations they tell you to call 911. :( PAT] ------------------------------ From: 6.vef@wrq.com (Steve Forrette) Subject: Re: 911 Circuitry Can Detect 91 Date: 12 Jul 92 02:26:32 GMT Organization: Walker Richer & Quinn, Inc., Seattle, WA X-Telecom-Digest: Volume 12, Issue 538, Message 3 of 10: > [Moderator's Note: My experience here has been that with either > *67, *70, *71, *72 (all return stutter dial tone) you can 'dial > through' ... that is, no pause is required in the modem string, etc. > Other places are different on this.

The name I've heard for the call forwarding feature used for voice mail services is "Call Forward No Answer" (different telcos, different names ... what a drag!) The situation with Call Forward No Answer with Bell Canada (in Quebec and Ontario) is that it's not offered to residential customers. I don't know whether it's offer to business customers though. The Call Forwarding No Answer feature is used by Bell for their own voice mail service (TeleReponse, in French) so they may very well be reluctant to offer it for the reasons you mention. The situation in British Columbia is different. BC Tel offers three species of call forwarding to its residential subscribers: (1) Call Forward No Answer. Forwards to a telco programmed number after a number of rings or when busy. (2) Call Forward Variable. This is the normal user programmable call forwarding. Bell Canada only offers this one. (3) Call Forward Fixed. Once activated, calls are automatically forwarded to a telco programmed number. (Not very useful it seems) Concerning telco voice mail: The one advantage that I get from subscribing to my telco's voice mail service rather then forwarding to my voice mail at work (if I could) is that the dial tone changes on my phone when I have messages. This is like the flashing LED on answering machines. You can quickly check if you have messages by listening to the dial tone rather than having to dial the voice mail number and to log in. Regards, Francois Truchon Bell-Northern Research, Montreal, Canada uucp: bnrmtl!francois@Larry.McRCIM.McGill.EDU [Moderator's Note: Ours is called 'Busy/No Answer Transfer'. In our land line service, this has to be permanently programmed in the CO and can only go to voicemail or another phone in the same CO. It cannot be turned on or off. But with our Ameritech cellular service, we can use *71 to turn it on and off at will, and send the forwarding wherever we please. IBT is part of Ameritech, so I wonder why the discrepancy?

Here in California, there seem to be two types of forwarding - on/off forwarding, and call forwarding on busy. The call forward on busy would take care of turning it on and off when you want to make a call, etc, and you can forward it anywhere you want, but that's not all you need. Those two seem to be the only things offered by Pacific Bell.

The idea seems to be to change the ESN so that free phone calls can be made on someone else's line. Anyone have any knowledge of potential problems etc? Does it work? If possible please E-mail. Best Wishes, Henry University of NSW, Sydney Australia. [Moderator's Note: What you suggest is highly illegal in the USA and probably everywhere else in the world except possibly the Netherlands where it seems that everything is okay where defrauding the telco is concerned. Another problem is that in most modern cellular phones, the chip containing the ESN is difficult to get into, let alone modify. They tend to be buried under wax, thoroughly soldered in place and with few or no markings on them. A third problem is that if you could easily change them (let's say you swap it out entirely for a bunch of little dip switches or pin wheels you set by hand), is that the place you call is recorded by the cellular company and if you intend to call anything other than hotel/radio station switchboards/contest lines, etc then eventually any regular calling pattern will be investigated.

It's interesting to read these comments in light of early attitudes about the impact of the telephone on home life -- well-documented in Carolyn Marvin's book "When Old Technologies Were New: Thinking about Electric Communication in the late Nineteenth Century" (Oxford University Press, ISBN:0-19-506341-4). The book, especially the second section, makes it fairly clear that there has historically been a variety of opinions about what social rights exist when a telephone is present in a household. The issue has never been resolved -- and probably never will be -- but many of the old issues are making a new appearance. There have been, of course, a number of changes in the expectations people have about the "public good" (for lack of a better phrase) new telephone technologies will play in society, and these are also reflected in many of the posts dealing with telemarketing as well. I'd like my students to see comments from participants in this forum about the issue of personal privacy as it relates to telemarketing and Caller ID. I'm going to go back through the archives to pull postings that pertain to this and collect them into a packet to give to my students. I wouldn't feel comfortable about doing this without the permission of the original poster, so I may be contacting you over the next few weeks to get your permission to use something you wrote. I'd also like to include the comments of people who may not have been moved to submit something to the Digest on this topic. If you feel so moved, please answer the following questions and mail the response to me (streeter@cs.unca.edu). Answer as many or few of the questions as you want (any and all help is appreciated!) 1. Who has the right to call you? What circumstances make this a less-than-straightforward question to answer? Are telemarketers the same as other people? Why or why not? 2. Does (or would) the existance of Caller ID on your home phone change your life in terms of the issues raised in #1? For PAT's sake -- so to speak -- send your responses to me and not the Digest since this has been a hot topic there.

A feature that I, too, hope could be added to the taylor-uucp distribution at some point. It's useful in other circumstances as well, including the converse of Marc Unangst's situation. I've a couple of long-distance sites where the charges are $19.50 for the first three minutes (or fraction thereof) within a three-hour "cheap" call window; at other times they're $31.50 for the first three minutes (or fraction). It's important to make one contact a day, even at the higher rate if absolutely necessary, but extra unneeded calls (even -- or actually, especially -- if successful) can be quite costly [One extra call a day at the higher rate, and I end up with nearly $1,000 more on that month's phone bill.] It'd sure be a lot easier to say "don't call within 18 hours of the last successful call" than to have to do the schedule tweaking I have to do now. Date: Mon, 13 Jul 92 10:40:57 HST From: Bob Cunningham Subject: Re: Suggestion for Taylor UUCP [Since several people have asked "where in the world" do you have to pay so much ...] Those are COMSAT/AT&T combined rates for INMARSAT-A satellite calls to ships at sea for the Pacific Ocean (rates to ships in the Atlantic are a dollar or so a minute cheaper). The ships I'm interested in are scientific research ships that we (University of Hawaii) operate, but setup is not unique; there's lots of outfits that work with ship at sea using modems, although as far as I know, we're the first to try using Taylor-UUCP for this. The calls are direct dial, with long-distance part to the nearest earth station included (from Hawaii, the nearest are in Australia and California, though that part is relatively cheap), the actual INMARSAT satellite link to the appropriate ship is the most expensive part. Incidentally, the same cost applies to voice calls between ship and shore. On board, they have a special phone for that, traditionally called the "gold phone" because of the rate. Even if they're not THE most expensive phone calls in the world, they're surely amongst the most expensive. ------------------------------ From: leavens@mizar.usc.edu (Justin Leavens) Subject: Recommendations on Waterproof/Resistant Cordless Phones Date: 13 Jul 1992 13:03:23 -0700 Organization: University of Southern California, Los Angeles, CA A recent incident in which my cordless phone (a Panasonic TX370 or something to that effect) took a little unexpected dip in our pool has led me to ask for recommendations on waterproof/resistant cordless phones. I've been to the department stores (who don't seem to carry them) and to a Circuit City (who didn't carry one either) and finally located a Fry's Electronics that had a Sony model and a Columbia model that claimed to be "water-resistant". Does anyone know about these products or have any experience as to how water-resistant these phones really are? While calling around, my basic request was "I want one that can float" (not really what I want, but I want it to be that resistant) and I was told that there are none that are completely "waterproof". Actually, my old Panasonic unit still works, sort of. It clicks incessantly when on-hook but on standby, beeps at me a few times before it will connect to the base unit and go off-hook, and pulse dials even though the setting on the base unit is set on tone (which is weird, could the base unit have been damaged when the handset went underwater in standby mode? If I hit the 'Tone' button on the handset it will dial in tones for that call ...). Luckily it was only a couple months old and is still under warranty. But I think I'd like to get one for 'pool use'. Any comments?

Levine About three months after I originally asked, the Post Office has sent me a handy 157 page book explaining Intelpost. It turns out to be Group 3 fax with optional pick up and delivery. There are seven different delivery options, not all available at every destination point including regular service in which the receiving post office drops it in the mail for local delivery, two-hour express service, pick-up with optional notification by phone or telex, and fax delivery if the recipient has a fax (presumably the sender doesn't.) To send an Intelpost message you can either drop off the originals at one of 200 post offices or establish an account and fax them to the P.O. yourself. The price is $10 for the first page, $4 for every additional page, $5 extra for any delivery option other than regular service. The cover page is free. Most of the 157 pages list what service is available where in the 39 participating countries. So, basically, it's fax for situations where the sender and/or receiver doesn't have a fax machine.

About 189 miles of communications system wiring, nearly enough to go from New York City to Baltimore. 56 video screens make up the podium's back wall. The podium has room for about 40 people and 8 TV locations. Delegation voting will be electronic with votes recorded via the pressing of one of three buttons: Yes, No or Abstain. There will be two phones mounted on each station with one for communicating with the podium and the other for calls to other delegations or outside locations. The four principal sponsors are American Express, AT&T, Time Warner and NY Telephone. 75 percent are involved in communications in one way or another and I'm not sure about Amex. I wonder who the lucky ones to end up paying for this will be -- the ratepayers or stockholders (I'm leaning toward the former). These paragons of society are giving $100,000 in cash and providing perks like cable TV and free magazines (that takes care of Time Warner).

IBT gave up ever trying to collect what they had coming from the Democratic convention here in 1968, and finally wrote it off, meaning of course we rate payers took a hit. I imagine the subscribers of NY Tel get to pay for this one, probably sometime around 1996 when it gets written off.

During the past year or so, a voicemail system calling itself the "Canadian Liberty Network" operated in Vancouver, British Columbia. The system operated out of a basement suite -- the owner of the home disclaimed any knowledge of the system, or the organization or individuals that operated it, even though he was "renting" the suite. The system amounted to a voicemail version of Dan Gannon's b-cpu bulletin board, with readings of the Leuchter report, "66 Questions & Answers About the Holocaust" and other material of a similar vein. Pressure from the Canadian government resulted in a court order which forbade the continued operation of the system. At that point, as I understand it, the system adopted a Washington State telephone number and continued to operate. I don't have enough details to know if the system itself remained in Canada, or moved south of the border, but the Canadian court just issued a contempt citation against the owners of the system, citing the continuing operation of the system in violation of the original order. (Canadian law prohibits dissemination of hate literature.) I would like to gather information about this system, or similar systems anywhere in North America, and solicit your assistance.

Oakland, Macomb, Genesee, Lapeer, St. Clair and Sanilac counties as well as small sections of Saginaw, Shiawassee and Livingston counties wil go into 810. Wayne, Washtenaw, Monroe, and small parts of Jackson and Lenawee counties will remain in 313. Detroit itself is in Wayne county and won't change. As with all NPA splits, rates won't change.

While we were waiting on the runway at O'Hare to take off (with 40-50 planes in front of us, according to the captain), a bad storm came through and shut down the airport. Out of sheer boredom during the delay, I reached for the GTE Airfone built into the seat in front of me. I waited for the green LED to come on before proceeding. It wasn't coming on. Eventually it did illuminate, but it was gone again before I could get my credit card through the magnetic reader. I assume with all those planes grounded on the runway in addition to those in the air that could not land, the call traffic was more than the system could handle. One lady who managed to get her card through the reader and dial a number heard a message stating that all circuits were busy and to please wait. This message repeated at regular intervals. She waited about half an hour before finally giving up. Now I'm wondering just what is the traffic capacity of one Airfone ground station? How many calls must have been in progress to jam it up like that? On a side note, I'd be interested in seeing a study showing how much extra Airfone revenue is generated for the airlines when there are delays versus flights that are on time (why be on time when you can make extra money by being late?).

"Pacific Bell spokeswoman Judy Peterson said a switch -- which served as the hub of service for the entire area -- lost power about 11:10 PM She said a portable diesel generator restored power by about 4:15 AM after a set of batteries failed to provide enough power." Evidently, the regular standby diesel generator failed when its transfer switch burned up. After the Loma Prieta earthquake there was a post-mortem talk by members of SMPTE that was broadcast on satellite.

C'mon Pat be nice. Using the bluebox is one thing, but somebody's account is quite another matter. See the difference? There has been quite a problem with the criminal side of "phreaking" with cellular phones here and I assure you it will earn you a room in one of the fine hotels operated by the police! On the technical side, several cellular phones can be fully programed externally, but I don't do this and don't know about changing the ESN or anything like that. We have three different systems here, ATF1 in the 150MHz band, ATF2 in the 470MHz band and ATF3 in the 900MHz band (470-890 is still TV here). We also have a public CT2 system called "Greenpoint" with Motorola Silverlink phones called "Kermits" with a green protective edge instead of the standard grey. Henson's famous frog is pictured on them. This system uses 40 channels between 864 and 868 MHz with a maximum transmit power of 10mW. While there are numerous features possible, it is only used as a payphone replacement at this time and as a home cordless phone. Full details are in EDSI prl-ETS 300 131.

Changing the ESN per se isn't illegal here in the UK. In fact it's become essential now that a number of cellular phone companies have started to "block" the ESNs of, for example, customers who disconnect to change to other cellular phone companies, so they can't use their phones on the network. Because a cottage industry has been set up to do this, its not too much of a surprise that as a result there has been a sudden increase over here of the "cloning" of working ESNs. This does result in fraud -- fraud against the registered user of that ESN -- and of course that is illegal. The problem is that it's not as easy to spot by checking bills, as Pat suggested. These phones are usually used to "sell" cheap international calls back home, to visitors and immigrants. There wouldn't be any pattern (other than the calls would all be expensive and international) and the people who receive the calls would genuinely know nothing about the criminal responsible. What has been done here, is to arrange for the Cellular system to "spot" cases where two phones are live on the system with the same ESN at the same time, or where a phone appears to "move" faster than normal between two different parts of the country. Not all cellular systems use our (ETACS) system; I believe USA uses AMPS and Oz uses something like GSM. So what may be possible in one country, is not necessarily possible in another.

And becoming more so. Over the past years (and particularly the past year) I have been under the impression that the US Mail has become slower and less reliable. Letters that used to take a couple of days to travel coast to coast now take a week. Mail to Los Angeles from here takes a good five days now (if it makes it at all). For the price of a stamp, you can send a fax anywhere in the country. It gets there immediately for sure. E-mail costs considerably less than that, reaches its destination in less than a day (most of the e-mail I send and receive takes minutes), and again the odds of being delivered are exceedingly high. Accordingly, I now only use the US Mail in the absence of any alternative. When it started taking three days for a letter to reach San Francisco from here (40 miles), I reassessed the communication food chain. Hence, I agree with Pat. If someone is proporting to be participating in electronic communications, then he had better be sure that he can deal with commensurate incoming traffic.

As Pat mentions, this is highly illegal, and there is a significant amount of technology installed in most cellular phone companies to detect this. When you get caught, your number can and probably will be distributed to one of several nationwide databases which will restrict your ability to use that phone.

In fact, most cellular switches I am familiar with are generally programmed to collect *everything*, including free, service, and even unanswered calls. Getting listings of calls made to/from certain numbers or calls made by a particular ESN are relatively simple. Tracking numbers that do not have the correct ESN or whose ESNs change is also not terribly difficult. There is also an effort taking place to establish a standard interconnect scheme between cellular companies to track fraud and cellular system abuse. This system, when in place, will make it extremely difficult to defraud cellular companies.

As former staffer for both the Federal Election Commission and a financially squeezed presidential candidate (Hart), I think I can shed some light on telco billing policies toward political parties and candidates. First, Watergate changed most things in terms of financing campaigns, and one was that vendors (including telcos) can no longer provide special favors or exceptions to normal billing practices to political parties or candidates. A write-off would now be subject to a lot of scrutiny by the Federal Election Commission, and unless it was done in accordance with normal business practices would bring a suit or indictment against the telco for an illegal corporate contribution. Normal telco billing policies require stiff deposits for newly constituted organizations, and campaigns are no exception. So the Brown or Perot campaigns are probably given little leeway payment-wise, not because of any judgment call about their finances (guess which one is a better risk?), but because political customers are scrutinized under federal law. Similarly, political parties now get no special treatment. If the 1992 bill to NY Telephone and AT&T was not paid, the Democratic National Committee would no doubt have all phone service to them cutoff in the NYNEX region and all AT&T service suspended. Also, given the nationwide credit database used by RBOCs, nonpayment would also endanger service everywhere. Back in the pre-divestiture days, telephone service to campaigns (including long distance of course) was handled by the candidate's local telco, even for national candidates. For example, when the Hart presidential campaign in D.C. wanted six additional phones in the Portland, Maine office, they wired deposit money to Mountain Bell in Denver, where Hart was Senator. As I recall, the Hart campaign used a succession of long distance carriers (MCI, Sprint, Alltel, and a few more) and ended up owing them all hundreds of thousands of dollars. I've heard the carriers have learned their lesson since 1984. I suspect there was a reason AT&T carried the national Democrats for so long. AT&T was and is quite regulated and their regulators include a lot of Dems, and they probably didn't want to lead the charge for payment. No need to anger anyone. As I said above, their patience would no longer be legally possible today. Finally, remember that each political party now receives a payment in the $10 million range for their conventions from the federal Presidential Campaign Fund (that's our $1 checkoff). So the Republicans no longer need solicit from the likes of IT&T (as they did at their 1972 convention -- long story) and the Democrats can pay their bills.

I remember seeing a story on television about "The Voice of the Phone Company" several years ago. If I remember correctly, Ramona was the lady who frequently recorded "time" and intercepts for TPC, but she retired and her sister (or cousin or other relative) Jane Barbie took her place (they have similar voices). The program I saw said these ladies were chosen for their lack of a regional accent (I don't remember where they are from) and a "friendly" quality in the tone of their voices (personally, I always thought intercepts sounded harsh and anything BUT friendly). I remember noticing that when one of them (probably Jane) was interviewed, she sounded much different and less harsh since she was was speaking naturally instead of uttering canned phrases. Apparently, Octel is quite proud that they were able to get Jane to record their prompts. When the company I used to work for installed its Aspen system, the vendor made a big fuss about the fact that it was Jane Barbie, "the same voice the phone company uses!"

Exchanges never transmit pulses to the far end. Remember: Pulses are just quick disconnects of the phone from the line -- there is (was) no reason to disconnect the other caller when you disconnect yours momemtarily. So, your CO (phone company equipment) isn't being "nasty", there's just no reason for the additional complexity of adding this feature which you think should exist. Customer equipment MIGHT theoretically be able to listen for "clicks" from pulse dialing and guess that these are pulses, but it would be a near-impossibility to get this to actually work from a technical aspect.

In fact, most CO's would probably accept "clickless" pulses which had triangle or sine-shaped wave forms instead of square pulses. The corners of the square pulses are what make the clicks. If someone were to ever build such a phone (might be kind of a novelty -- silent dialing) there is NO possibility of customer equipment at the far end ever decoding for it (unless maybe it detected gaps in the caller's breathing cause by the disconnection pulses? :-) Followups please CC me via mail -- my newsfeed has leaks - TIA. ------------------------------ From: schuldy@progress.COM (Mark Schuldenfrei) Subject: Surprise Calling Card Fraud: Followup Organization: Progress Software Corp.

She also suggested that the originating phone numbers for the calling card calls were probably residences. This gives me a real urge to make long distance call or two, and imply I'm an immigration officer. But that would be illegal, and I shall not do it. Best of luck to AT&T's stockholders, however, it seems that the fraud unit is willing to write off $1000 dollars at a time. Oh, and for your information, the hotel group in question is the Art Deco Hotels in Miami Beach, dba the Lesley, Carlyle and Cardozo. Do not make calling card calls from their rooms, is my best advice. Mark Schuldenfrei, speaking for myself only, and not for my employer, or the INS for that matter...

During the past year or so, a voicemail system calling itself the "Canadian Liberty Network" operated in Vancouver, British Columbia. The system operated out of a basement suite -- the owner of the home disclaimed any knowledge of the system, or the organization or individuals that operated it, even though he was "renting" the suite. The system amounted to a voicemail version of Dan Gannon's b-cpu bulletin board, with readings of the Leuchter report, "66 Questions & Answers About the Holocaust" and other material of a similar vein. Pressure from the Canadian government resulted in a court order which forbade the continued operation of the system. At that point, as I understand it, the system adopted a Washington State telephone number and continued to operate. I don't have enough details to know if the system itself remained in Canada, or moved south of the border, but the Canadian court just issued a contempt citation against the owners of the system, citing the continuing operation of the system in violation of the original order. (Canadian law prohibits dissemination of hate literature.) I would like to gather information about this system, or similar systems anywhere in North America, and solicit your assistance. It is my belief that the folks who operate these systems are either formally or informally linked to and supported by American Nazi front organizations, i.e. Carto and company, but I cannot substantiate that belief. Any and all information, including news clippings/citations, sound bites, etc. will be appreciated. Printed material, including newspaper clippings, Nazi literature advertising these systems, etc. can be sent to me via snail: Ken McVay c/o R.R. 1, C-28 Ladysmith, British Columbia, Canada V0R 2E0 NOTE: I was asked, after posting this request in its original form, whether or not I would use the information collected to assist the Canadian government in its efforts WRT this matter. The answer to that question is an emphatic no, although I _will_ most certainly make public use of information received which I can confirm, and that may very well result in the government's obtaining the information anyway. If you wish to contribute to my education, but do _not_ want your information used in any public or private forum beyond my "eyes only," please make that clear -- your request for complete confidentiality will be respected without reservation.

Levine UPI reports that the 313 area will split to a new 810 code effective 10 Aug 1994. Oakland, Macomb, Genesee, Lapeer, St. Clair and Sanilac counties as well as small sections of Saginaw, Shiawassee and Livingston counties wil go into 810. Wayne, Washtenaw, Monroe, and small parts of Jackson and Lenawee counties will remain in 313. Detroit itself is in Wayne county and won't change. As with all NPA splits, rates won't change. The telco consulted lots of local leaders so there seems to be little grumbling about the boundaries.

WXYT said that Michigan Bell announced that area code 313 will continue in Wayne, Washtenaw, and Monroe counties. Counties north of Eight Mile Road including the north and northeast Detroit suburbs will go to area code 810 in August '94. A Michigan Bell spokesperson came on to say that this will not impact long distance phone rates. Do they mean that you will have to use the new code after that date, or that you'll be able to? I understand that area code splits usually involve a transitional period that this brief radio story did not mention.

While we were waiting on the runway at O'Hare to take off (with 40-50 planes in front of us, according to the captain), a bad storm came through and shut down the airport. Out of sheer boredom during the delay, I reached for the GTE Airfone built into the seat in front of me. I waited for the green LED to come on before proceeding. It wasn't coming on. Eventually it did illuminate, but it was gone again before I could get my credit card through the magnetic reader. I assume with all those planes grounded on the runway in addition to those in the air that could not land, the call traffic was more than the system could handle. One lady who managed to get her card through the reader and dial a number heard a message stating that all circuits were busy and to please wait. This message repeated at regular intervals. She waited about half an hour before finally giving up. Now I'm wondering just what is the traffic capacity of one Airfone ground station? How many calls must have been in progress to jam it up like that? On a side note, I'd be interested in seeing a study showing how much extra Airfone revenue is generated for the airlines when there are delays versus flights that are on time (why be on time when you can make extra money by being late?). Jeff Garber <507-5968@mcimail.com> My opinions are just that. ------------------------------ From: bob@sunspot.noao.edu (Bob Riegelmann) Subject: Telling my Tip From my Ring Organization: National Solar Observatory/SP, Sunspot NM, USA Date: Tue, 14 Jul 92 15:51:47 GMT I'm re-wiring my house, and I need a trivia answer. To avoid confusing local craftpersons after I leave this house, is there a protocol that associates tip and ring with the color and color stripe wires? i.e. does tip go on the blue wire, and ring go on the blue/white wire? or reverse? Don't ask me why I'm rewiring, but this house was originally wired by the Air Force, and was recently on linebacker. Needless to say, nothing worked when I moved in.

Kaufman) Subject: 911 Outage in Santa Clara Organization: Computer Science Department, Stanford University. Date: Tue, 14 Jul 1992 16:46:14 GMT (from the local news): "Santa Clara County lost its 911 emergency system in most areas for more than five hours Sunday night and this [Monday] morning due to a power outage and the failure of a battery-based backup system, phone company officials said." "Pacific Bell spokeswoman Judy Peterson said a switch -- which served as the hub of service for the entire area -- lost power about 11:10 PM She said a portable diesel generator restored power by about 4:15 AM after a set of batteries failed to provide enough power." Evidently, the regular standby diesel generator failed when its transfer switch burned up. After the Loma Prieta earthquake there was a post-mortem talk by members of SMPTE that was broadcast on satellite. It seems phone companies don't want to test emergency power systems because "it can cause disruptions", so when they are needed they are untested.

C'mon Pat be nice. Using the bluebox is one thing, but somebody's account is quite another matter. See the difference? There has been quite a problem with the criminal side of "phreaking" with cellular phones here and I assure you it will earn you a room in one of the fine hotels operated by the police! On the technical side, several cellular phones can be fully programed externally, but I don't do this and don't know about changing the ESN or anything like that. We have three different systems here, ATF1 in the 150MHz band, ATF2 in the 470MHz band and ATF3 in the 900MHz band (470-890 is still TV here). We also have a public CT2 system called "Greenpoint" with Motorola Silverlink phones called "Kermits" with a green protective edge instead of the standard grey. Henson's famous frog is pictured on them. This system uses 40 channels between 864 and 868 MHz with a maximum transmit power of 10mW. While there are numerous features possible, it is only used as a payphone replacement at this time and as a home cordless phone. Full details are in EDSI prl-ETS 300 131. Call +33 92 94 42 00 or 93 65 47 16 in France for more information.

Changing the ESN per se isn't illegal here in the UK. In fact it's become essential now that a number of cellular phone companies have started to "block" the ESNs of, for example, customers who disconnect to change to other cellular phone companies, so they can't use their phones on the network. Because a cottage industry has been set up to do this, its not too much of a surprise that as a result there has been a sudden increase over here of the "cloning" of working ESNs. This does result in fraud -- fraud against the registered user of that ESN -- and of course that is illegal. The problem is that it's not as easy to spot by checking bills, as Pat suggested. These phones are usually used to "sell" cheap international calls back home, to visitors and immigrants. There wouldn't be any pattern (other than the calls would all be expensive and international) and the people who receive the calls would genuinely know nothing about the criminal responsible. What has been done here, is to arrange for the Cellular system to "spot" cases where two phones are live on the system with the same ESN at the same time, or where a phone appears to "move" faster than normal between two different parts of the country. Not all cellular systems use our (ETACS) system; I believe USA uses AMPS and Oz uses something like GSM. So what may be possible in one country, is not necessarily possible in another.

And becoming more so. Over the past years (and particularly the past year) I have been under the impression that the US Mail has become slower and less reliable. Letters that used to take a couple of days to travel coast to coast now take a week. Mail to Los Angeles from here takes a good five days now (if it makes it at all). For the price of a stamp, you can send a fax anywhere in the country. It gets there immediately for sure. E-mail costs considerably less than that, reaches its destination in less than a day (most of the e-mail I send and receive takes minutes), and again the odds of being delivered are exceedingly high. Accordingly, I now only use the US Mail in the absence of any alternative. When it started taking three days for a letter to reach San Francisco from here (40 miles), I reassessed the communication food chain. Hence, I agree with Pat. If someone is proporting to be participating in electronic communications, then he had better be sure that he can deal with commensurate incoming traffic. The day is coming when we all will look at paper mail as passe and archaic. I know I already do. John Higdon | P. O. Box 7648 | +1 408 264 4115 john@zygot.ati.com | San Jose, CA 95150 | M o o !

A settlement on national bargaining issues had been announced earlier, on July 1, by AT&T, the Communications Workers of America (CWA), which represents 100,000 workers at AT&T, and the International Brotherhood of Electrical Workers (IBEW), which represents another 27,000. However, that settlement was contingent upon successful completion of further talks on issues specific to various individual work groups and manufacturing plants. The local issues settlement came late last night following intense bargaining sessions that saw negotiators meeting at one point for 43 straight hours from Friday through yesterday morning. Membership ratification of the complete settlement package will take several weeks to complete, the unions reported. Strengthened employment security was identified as the unions' chief goal in the talks, and union negotiators said they had achieved further gains in this area in the local talks. The national settlement calls for over 30 improvements in the employee job transfer system at AT&T, as well as access to a larger pool of available jobs and a better chance to be rehired into new jobs. The settlement also boosts base wages for most workers by 12.3 percent over the three years, provides $3,300 worth of AT&T stock to each employee, raises pension benefits by 13 percent, and expands worker training and family care provisions. ------------------------------ From: jongsma@esseye.si.com (Ken Jongsma) Subject: AT&T Voicemark Date: Wed, 15 Jul 92 15:57:08 EDT I had an occasion to use AT&T Voicemark (The store and forward message service) the other morning. First, a kudo ... I needed to record a message at 5AM the other morning for delivery later in the morning, but I couldn't remember the Voicemark number. (Actually, I did remember the number, but thought it was a 700 number like Alliance, when it really was an 800 number.) Anyway, I called the 1-800-CALL-ATT number, waded through the menus and got to a live operator. I asked her for the Voicemark number. Within 60 seconds she found the number, apologized for taking so long and connected me to the number herself. (She said they had a huge book of various AT&T departments/products and it took a while to find things.) All this at 5AM. I was impressed. Anyway, Voicemark worked as advertised. A couple of comments, since I know at least one Voicemark engineer reads the Digest: Please add the ability to send the same message to multiple numbers. it's a drag having to rerecord the same message. Voicemark stumbles when it encounters an answering machine. I did not know that one of the target numbers was answered by a machine. Voicemark called the machine at the designated time and left my message. Fortunately the machine recorded the message. It didn't know what to do when Voicemark said "Press # to reply" though! Eventually Voicemark gave up and hung up. I could have told Voicemark to use a live operator, had I known there was a machine on the other end, but I didn't know at the time.

Well, you can't do that. These phones capture the number and kill the dial after 0 + AC + number. They then outpulse the number with the receiver muted. When the "bong" occurs, you can dial 0, but that just gets you the AT&T operator. I expected something more automated. Anyone know why these phones are stickered this way?

Florida Attorney General Bob Butterworth said Southern Bell Telephone Co. owes $14 million in refunds to customers who were pressured into ordering expensive services or billed for services they did not order. Phone companies in Pennsylvania, California and Wisconsin also have been fined or ordered to make restitution for deceptive marketing, said Gene Kimmelman, legislative director of the Consumer Federation of America in Washington. Southern Bell spokesman Spero Canton said Tuesday that a few dishonest sales people were to blame and were no longer with the company. He also said that when the company found out about the practices 1 1/2 years ago, it refunded more than $850,000 to about 30,000 customers. Butterworth, however, said company employees tried to persuade customers to accept only a fraction of what they were owed. To help alert consumers to refunds they might be owed, Southern Bell, one of the so-called Baby Bells created by the breakup of AT&T, planned to place full-page ads in newspapers around Florida encouraging customers to check their bills. Canton said bills were being itemized this month to provide a rundown of charges. Customer service hours would be extended for the next two weeks to handle calls, he said. Butterworth said Monday he would sue to force the company to make refunds to at least 225,000 of its 4.7 million Florida customers. "We all grew up trusting Ma Bell," Butterworth said. "We didn't expect to encounter Ma Barker." The optional services included touch-tone dialing ($1 a month); call forwarding ($2.45 a month); call waiting ($3.50); speed calling ($2.20 to $3); and wire maintenance (up to $2.50 a month), in which the phone company agrees to fix problems inside a customer's home. Before the American Telephone & Telegraph Co. monopoly was broken up by court order, the maintenance service was free. Kimmelman said watchdog groups such as his are pushing in Congress for safeguards against such abuses. The federation is backing a bill passed July 1 by the House Judiciary Committee that would limit phone companies from getting into new information services so long as they remain the local monopoly. In 1990, Bell of Pennsylvania was ordered to pay $42 million in refunds. That same year in California, Pacific Telesis Group was ordered to refund $3.5 million. In 1989, Wisconsin Bell was fined $1.2 million. ------------------------------ From: ramrod!chrisc@lmt.mn.org (Chris Cox) Subject: Newport LAN2LAN/Compression Error Rates Organization: LaserMaster Technologies, Minneapolis, MN USA Date: Wed, 15 Jul 1992 13:35:30 GMT We have been using a pair of Newport LAN2LAN/Compression NIC's providing a wide-area link between Minneapolis and Amsterdam for about six weeks now.

As some of you may know, Pac*Bell's monopoly on intraLATA calling will be ending in the forseeable future. The ads proudly tout the fact that with the Pac*Bell Calling Card "it is never necessary to dial an access code". Well, as they always say in business, if you have a liability -- feature it. While AT&T tells you that to avoid being ripped off by AOS slime you should dial the AT&T access code, Pac*Bell says go ahead and get screwed. At least you don't have to dial an access code! As I have noticed over and over, AOS criminals cannot accept the AT&T-only card while, of course, they readily accept an LEC card. Hence, "no need to dial an access code". The other face of the access code mention is that when intraLATA competition is a reality, it will be necessary to use a code if you wish to use a different carrier than Pacific Bell. By indoctrinating the public with the notion that using an access code is "inconven- ient", it will enhance its position as default carrier. These very misleading commercials point out what I have been preaching for years. Advertising is not meant to inform, only to sell. How many people do you think there are out there who actually believe that "Friends and Family" is just the cheapest plan there is? I would wager that it is quite a few and that would indicate a very successful campaign. On July 27, Pac*Bell will launch its new Centrex spots. All of the Centrex advertising that I have seen so far is borderline fraudulent. Example: A software company executive in Scotts Valley is crowing about how he stayed "up and running" after the earthquake because he had Centrex while a neighbor business with a PBX was down (no power) for two days. Yeah, right! I wonder how the software company kept its computers running for two days, or did the people just talk on the phone shooting the breeze? And even if it DID keep its computers running on backup power, why would that have not worked for a PBX switch? I will be eagerly awaiting Pac*Bell's latest Pac of Lies. John Higdon | P. O.

Get "blocked ID blocking", which would play a recording at the CO saying "I'm sorry, but you need to disable blocking on your line before calling this number" if someone called with their ID blocked.

But how can you promote caller ID as the cure-all for the nuisance calls? I am not smart enough to look at a number and determine who is making the call. May be it is my wife calling from a payphone to tell me that her car went kaput on the way home. Or it may be the sales-slime. Is there something more to the caller-ID than I know of? All it can do is flash the caller's number on a display on the callee's phone, right? If I am at the receiving end, and do not recognize the call I want to pick up the phone and find out who it is, just in case it is something important. james joseph joseph@c2a.crd.ge.com [Moderator's Note: Although I use Caller-ID to screen calls, I use it more as a way to have recourse to a (previously) unknown caller for whatever reason.

PAT] Caller-ID is almost useless for this purpose. My friends don't always call from the same numbers, people I do business with don't always call from the same numbers, telemarketers don't call from the same numbers, and, the biggest current problem, most telemarketers seem to call from other LATAs anyway. If an unknown number appears with Caller-ID, it could also be a telemarketer. But, if a friend is calling from a non-standard location I don't want to miss the call -- the topic is probably more important than idle chatter. Caller-ID can sometimes be useful to show that friends are calling, but if the number isn't a friend's number then the number is almost always useless. It only helps with repeated annoyance calls from the same number (or bank of numbers). > [Moderator's Note: ...

Caller-ID is about as useful as a peephole that only shows the color of the caller's socks. It will help if a friend has a distinctive pair of socks, but a pair of white socks doesn't tell you anything. B.J. ------------------------------ From: wolves!ggw@duke.cs.duke.edu (Gregory G.

This, I suggest in turn, is *not* the answer. Caller-ID will tell me if a caller from a properly equipped exchange is at a particular number. It does not tell me *who* at that number is calling. It helps, but not much. It also does not cover situations where someone is calling from somewhere else. It simply returns the number from wherever they are calling. Once again, there is no way of knowing *who* is calling in particular. There are systems available that allow someone to give out special codes so that "special" people can be identified by their dialing, but these are not always available, or universally applicable. (Consider someone calling from a COCOT that blocks touchtone after connecting; several systems will not work in such cases.) About the only one that works in any sort of universal fashion is the "distinctive ring" that assigns multiple numbers to one pair and rings in different fashions, but that is not universally available, and costs to bloody much for most folks tastes.

It provides long-distance telecom routing at the lowest cost using SL-100's and other assorted goodies. To get to any site in North America or the UK, one dials 6 + ESN + extension.

Any Dutch telephone has four wires named a, b, e and eb. The standard coloring for the wires is: a = red b = blue e = green eb = yellow A and b correspond to tip and ring in the US. Connect those to the wire pair from your phone company. Polarity is unimportant. If you want the internal ringer to operate you must connect wire eb to b. If you want an external ringer to operate together with the internal one, connect it between eb and b. This puts it in series with the internal ringer. If you don't want the internal ringer to operate, don't connect eb. Do not connect the e (earth) wire. It is needed to generate an out-of-band signal to PBXs by pressing the white (in some sets black) push button. This type of out-of-band signal is (to my knowledge) not used outside the Netherlands. If your phone is indeed a T65 or other model with mechanical ringer, you can adjust the volume of the ringer with the toothed white wheel in the bottom of the set. There is a big and a small bell symbol near this wheel indicating higher and lower volume. Peter Knoppers - knop@duteca.et.tudelft.nl ------------------------------ Subject: European Phone in Canada?

Do you have a schematic? Here in Holland this would NEVER work, because on the newest network you not only send an ESN, but also an answer to a 'question' from the cellular exchange. This 'signature' is generated by a little module that you can't open (it's one chip). So you can only replace the module by another one, but then it would not match with the numbers stored in the cellular exchange. There IS no easy hack into this one, in fact there might not even be a complicated one.

In the very early days, ESN tampering was common. PAT] The EIA spec (which was incorporated verbatum within FCC rules) always specified that the ESN was to be, "buried within." It was intended to be installed within more than one solid state device so that tampering with any portion would render the apparatus permanently inoperable. The manufacturers (like Motorola) that made equipment that allowed it's ESN to be changed in the field did not comply with the letter or the spirit of the law.

Here's and intersting little first-hand account. My GTE Mobilenet bill is always small enough, and I travel little, so checking it every month is easy. Last month, I had over $80 of fraudulent calls on my bill, including one marathon hour plus call placed in New York. As this has happened once before, I knew to call customer service and they gave me credit for the fraudlent calls no questions asked. Curious about GTE's lack of interest in following up on this, I called my account manager and asked him what GTE was doing about fraud. He said that, since I brought it up, they'd like to change my number. I said OK. What a pain in the behind!! I thought that they would just cancel the old number and give me a new one to put in my phone. No, I had to fill out a whole new service application, with all the financial info on it. I did it anyway,'cause I pursuaded them to give me a cooler number. However, when I was done, I called my account manager back and said that, if they were serious about beating the hackers, they were going to have to make the number changing process easier. He said, he'd look into it.

My wife is a customer service manager for BellSouth Cellular, which provides cellular service throughout much of the southern US. Her office has a bulletin board covered with "fraud alert" notices generated by BellSouth Cellular HQ in Atlanta. Perhaps not surprisingly, the bulk of reported frauds involve "human engineering": providing fake information to establish service, activating several numbers then leaving town, and so on.

I don't think that would be very smart. For example, while I'm at college I use my parents Sprint FON card, and I'm about 100 miles apart from them. So let's say my father goes to San Francisco on business and uses his card to call home/wherever and I'm calling long distance somewhere else. I'm sure one of us would be really ticked off if we wouldn't make our calls. I know many students here at A&M who also use thier parents long distance calling cards.

Probably because they'd PO a bunch of *legitimate* customers. I used to have four people sharing a house with me. We *all* had AT&T calling cards which (as is *normal*) had the same card number and the same PIN.

A friend of mine at a small midwestern university has been having a horrendous cracker problem on their main Sun system that's connected to the Internet. One of the problems that he is having is that the computer center there didn't take the cracker seriously until a few days ago, when he rebuilt a new kernel, and rebooted the system (!). My friend isn't a computer center employee, he's a humanities and social science professor that is probably the most skilled person in the SunOS/UNIX environment at the school, but because of internal politics, the computer center staff and director is unwilling to give him much responsibility, and he really doesn't want that much, he would much rather have the computer center staff doing their jobs and learning about the system rather than spending their time installing copies of the latest DOS spreadsheet, but unfortunately, their level of expertise, coupled with their immense desire not to work more than eight hours a day, has caused this cracker problem to get out of hand. Imagine a system that has more suid programs than users! Their password file is readable by all, and various password cracker programs have been run against it and many accounts have been compromised. In our discussions of computer break-ins, this is a classic example of the system administrators not doing their job, even after getting information from CERT and Sun on how to plug their many holes. I generally have sympathy for the type of person that I call a hacker, one that explores but doesn't disrupt or destroy, but this person is not a hacker; he is a malicious person somewhere in the world (they think he's in Australia) that has not only refused to stop accessing the system after repeated requests by e-mail, but also has root privledge and the skill to modify the kernel to do his bidding. He engages in a cat-and-mouse game that often culminates in my friend or one of the system administrators knocking him off of the system, just to have him reappear and knock the legitimate users off of the system. I have included his latest e-mail that he has sent to many of the faculty and staff at the university. Notice the adolescent logic that he uses and the premise that he is only helping to "enhance" security, and how he is doing them a service by knocking other crackers off of the system. Things like this infuriate me, because certainly one side of the situation is that the system administrators aren't doing their jobs (for whatever reasons), but the other side is that little shits like this are what may cause the internet to crumble because no organization will want to be connected to it. What would you do in my friend's situation?

Well Mike, you had me leaning towards your side until I read the 13 July edition of {ComputerWorld}, specifically the article "Wiretap snares alleged hackers". In that article, you state: "This whole indictment could very well be an attempt to frame some people who the authorities believe glorify hacking." This sounds like a sensationalist defense strategy to me Mike. Why does it have to be a conspiracy on the part of the government to frame these people? Maybe the government just bungled another investigation, since they do have a pretty fair track record of doing that. Though you carefully couch your statement so that the wording cannot be legally used against you, when it is all boiled down you are doing the same thing that PAT did when he said: "Let's listen to the shrill chatter from the EFF ..." PAT is just a little less selective with his wording.

According to the {New York Times} (July 10 at B1), NY Tel has charged the Democrats over $600 for each line it installs at the Garden (more than twice the price the Republicans will be charged in Houston -- I guess telcos have long memories). The breakdown is as follows: $150 is the "regular" charge for installing a business line (I'm glad I don't live there), plus $207 as a "special-event charge" (because they have to take the lines out four days later -- this is $9 less then the Dems were charged in 1980), and the remaining $250-odd dollars is a deposit for all those message units and tolls. Considering that there are several hundred lines installed at this bargain rate, I think NY Tel would have to work hard to lose money on this job. As for the poor Democrats, this is the price they have to pay for meeting in NYC. When will they ever learn how to save money? [Moderator's Note: The big news today of course is that Ross Perot has pulled out of the campaign, and things are looking brighter for the Democrats than anytime in the past twelve years.

Any and all information would be appreciated. ------------------------------ From: MPA15AB!RANDY@TRENGA.tredydev.unisys.com Date: 18 JUL 92 09:40 Subject: GTE and CLASS/ISDN I called the GTE business office to ask them when the rest of CLASS would be offered (sans CLID), and also to ask about SS7 links to PacBell (I have had Busy Number Redial for some time, but only for numbers within the switch (which is surrounded by PacBell areas)). I asked when ISDN would be available ;-). The rep said CLID hadn't yet been approved by the PUC! When I pointed out that the PUC had approved it weeks ago, and mentioned the front-page articles in the {L.A. Times} and other papers, she said they were flat wrong. She started to suggest I call the business service reps to ask about ISDN, but then remembered that the business and residence reps were the same. She did give me another number to call, though. A media rep called me back from the other number, and he seemed to know what he was talking about, and to be quite reasonable. (Quite a change from the business office types!). He said November was the target date for CLASS features other than CLID, Call Trace, and Call Return. He said GTE's objection to CLID was that they felt it was impossible to educate people about what CLID was and what it meant, and how to ensure your number was or wasn't displayed in an environment with three forms of blocking and no way to know which is in effect for any given line. I suggested that they offer a code which would read back the state of all options, and he said he liked the idea but it would have to come from Bellcore. He mentioned that California has the most sophisticated phone consumers in the country, and also some of the least sophisticated, who come from countries where you can't even get a phone, and trying to educate them about CLID would be very hard. He said Call Trace would take longer to implement because of the education requirement. As for Call Return, he said they wouldn't want to offer it right away, because if you returned a toll call, the number would show up on your bill. He said GTE was considering a billing modification that would blank out the last four digits of the number in such cases. He said I was the first person ever to ask him about ISDN :-( Regarding SS7 links, he said GTE was working on them between their own switches. Links to PacBell would come, but he didn't know when. On other matters, he said he was bothered by the practice of IXCs selling ANI data, especially when the customers turn around and use it for marketing and other purposes. That surprised me, coming from a phone company representative. He said he wasn't aware of "block blocking" (Anonymous Call Reject). Didn't the PUC order it as part of CLID in California? Anyway, he promised to have someone call me back with more information on SS7 links, CLASS availability, and ISDN.

Note that NAP is an interesting product, in that it is a break from the traditional way of doing telephony applications. The usual approach is to use small, dedicated computers, often coresident with the switch. NAP is a platform that runs on large, general purpose computers which supports a variety of voice applications. Among the advantages of using this approach are that you get the security and data integrety afforded by large computers, the 4GLs and environmental software to develop orp enhance voice applications quickly, and the scalability of the hardware. I don't work with NAP, but I try and follow the developments. UNISYS NEWS NETWORK, JULY 9, 1992 UNISYS WINS MAJOR TELECOMMUNICATIONS CONTRACT The Telecom Corporation of New Zealand has purchased the Unisys Network Applications Platform (NAP) as the first step in enhancing its soon-to-be deployed intelligent telephone network. The NAP system will allow Telecom to offer a variety of voice messaging and fax services to its customers. NAP will offer as many as 11,700 simultaneously accessible message ports and accommodates approximately 1.6 million voice mailboxes. Telecom services approximately 1.4 million telephone lines and expects about 50,000 customers to use its message center. "The Unisys system was chosen for its ability to handle a large number of calls and to deliver the high level of service Telecom customers expect," said Barry Bailey, Telecom's Networks Organization managing director. "Another major influence in the decision was the fact that the same system is already used by a number of telephone companies around the world." As equivalent of the now widely used PC voice and fax boards, with digital and/or analogue interconnections, has been built for the large platform. This provides a much more flexible application development environment for integration with corporate database repositories. NAP gives Telecom an advanced development environment in Unisys LINC, and a powerful processor. The open nature of this platform also allows interface with databases from information suppliers, which allows Telecom to provide a comprehensive range of audiotext and interactive voice response services. "The new Unisys System will give us the ability to provide both our residential and business customers throughout New Zealand in the next year and into the future, with a wide range of products and services such as Message Delivery and Fax Mail," said Telecom's corporate executive, sales and marketing, Tom Potrykus. It can accommodate the integration of facsimile and electronic mail messages into a "universal mailbox". The system is also being developed to cater for video and images. Applications for the system will be developed in Wellington by the Unisys-owned systems integration company, SynerCom. -------- Randy Gellens randy%mpa15ab@trenga.tredydev.unisys.com >>>>>>> If mail bounces, forward to rgellens@mcimail.com <<<<<<<< Opinions are personal; facts are suspect; I speak only for myself ------------------------------ From: leavens@mizar.usc.edu (Justin Leavens) Subject: CLASS Services Available from Pacific Bell Now! (Well, Almost) Date: 16 Jul 1992 11:35:31 -0700 Organization: University of Southern California, Los Angeles, CA I got a call last night informing me that Pacific Bell was now authorized to offer the three CLASS services to residential customers and have them activated July 21. These services are Select Call Forwarding ($3.50) BusyRedial ($3.50) and Priority Ringing ($4.00). Of course, "the more you buy, the more you save", and they give 15% discounts on two features (which includes the old, standard features like Three-Way and Call Waiting), adding a 5% discount for every feature up to 30%. My setup now includes Call-Waiting, Three-Way Calling, BusyRedial, Priority Ringing, and The Message Center for $16.10 a month (plus basic rates and all that other good stuff). Pacific Bell is also waiving the $5.00 installation fee on these new services for a couple of months. A couple of questions maybe for PAT and others who have these services already: Do they work outside your local telephone area (that's the LATA, right?)? The rep I spoke to said that they weren't sure yet whether or not out of area calls would be handled correctly, even calls from local GTE areas. I know SS7 is in place and working to some degree, but is it fairly well implemented for these features to work USA-wide, as long as the switches are new enough to handle it? Justin Leavens University of Southern California [Moderator's Note: In IBT territory, three-way and call-forwarding work anywhere we can dial, local, interstate or international. Message Center takes calls from anyone who rings you anywhere. Callers cannot dial direct or be direct call-forwarded to Message Center; they must connect through transfer on busy/no answer via your number. What you call 'Busy Redial' we call 'Repeat Dialing'. It and 'Return Last Call Received' work (almost) anywhere in the IBT LATA, but not elsewhere. We have two styles of 'priority ringing'. One is in the form of a second and/or third telephone number which rings on your main line with distinctive ringing. Anyone dialing those numbers comes through with short rings, etc. We can elect to have those numbers follow call forwarding or not; if not, then even if the main number is forwarded, the additional numbers on the line will 'ring through'. If they 'ring through', then they follow whatever the main line would do regards message center, call-waiting, etc, but as they have distinctive rings, they also have distinctive call-waiting signals. The other style of 'priority ringing' involves designating up to ten numbers which when they call you cause a distinctive ring and will or will not follow call forwarding instructions as designated. These have to be in the IBT LATA.

Their convictions are overturned. By Philip Hager Times Legal Affairs Writer SAN FRANCISCO -- A husband's secret tapes of his wife's suspicious telephone conversations with her lover were improperly used to convict the two of murdering the husband, the state Supreme Court ruled Thursday. In a rare defeat for prosecutors, the court ruled unanimously that federal law bars a family member from wiretapping the family telephone and that the tapes cannot be used as evidence in a criminal case. The justices rejected the state's two key contentions in the case: that the law permits domestic or "interspousal" wiretapping and that even if illegally made, the tapes were admissible because the government was an innocent recipient of evidence acquired by a citizen. The court acknowledged that the tapes were the "linchpin" of the prosecution's case but reluctantly concluded that the two lovers' conviction must be reversed. "We may question the wisdom of Congress in adopting such a broad-based suppression [of evidence] sanction," Justice Armand Arabian wrote for the court. "... We may not, however, substitute our judgment for that of [Congress]." Deputy State Atty. Gen. Morris Beatus said an appeal to the U.S. Supreme Court will be considered. If an appeal fails, prosecutors hope to retry the accused killers even without the taped evidence, said Assistant Santa Clara County Dist. Atty. Joyce Allegro. "In an egregious case like this, it's really a shame that the tapes cannot be used," she said. "There was no government impropriety here." Mark L. Christiansen of Sacramento, lawer for the male defendant in the case, praised the ruling, saying it will strengthen legal barriers against wiretapping by third parties. "This is going to make home telephones much more secure," he said. "Even in the best of families, one spouse may prefer that the other not overhear everything they say." Laurance S. Smith, attorney for the female defendant, called the ruling "a tremendous victory" for the right to privacy. "If this decision had gone the other way, anyone in a household could tape conversations by anyone else in the household," he said. "And if there was anything juicy, it could be turned over to the local prosecutor." The case arose in 1986 after Joe Otto, a 61-year-old electrician, became suspicious of his wife, Brenda, a 39-year-old divorcee he had married a month before. Otto hid a voice-activated tape machine under a bed. It recorded all calls in or out of the couple's home. One tape picked up a whispered conversation between Brenda Otto and Marvin Mark, in which Mark said "everything was wrong" and "I tried every possible way," but then added: "I got a better plan." An uneasy Otto played the tape to his daughter and a neighbor who was a police officer. In response to his daughter's concern, Otto began carrying a gun under his jacket. He also gave his daughter a copy of his will in which he left her virtually all of his $300,000 estate and gave Brenda $1. Three days later, another call was taped in which Brenda Otto and Mark spoke cryptically about the daughter being absent from the home that night. Later in the evening, Otto was bludgeoned to death. The body was discovered after Brenda Otto appeared screaming and naked at a neighbor's home, claiming robbers had killed Otto and assaulted her. --------- [I can understand it being illegal to tap one's own phone, and also that evidence received through government (police) misconduct should be suppressed. It also makes sense to me that if you illegally tap your phone, you shouldn't be able to profit from it, such as by using the tapes in a civil suit. But if the government had no hand in making the tape (didn't put you up to it, etc.), then the tape should be usable in a criminal case. -- RCG] Randy Gellens randy%mpa15ab@trenga.tredydev.unisys.com >>>>>>> If mail bounces, forward to rgellens@mcimail.com <<<<<<<< Opinions are personal; facts are suspect; I speak only for myself ------------------------------ Date: Sat, 18 Jul 92 07:32:54 EDT From: dwn@dwn.ccd.bnl.gov (Dave Niebuhr) Subject: Official Area Code 718 and 917 Annoncement The July "Hello" insert in my NYTel bill announced to the public that area code 718 was moving to the Bronx, thus leaving Manhattan as the sole holder of area code 212. The details are and I quote: "From July 1, 1992 throught May 15, 1993, calls to Bronx customers will be completed whether the caller dials 212 or 718. During this period, there will be no change for Bronx customers dialing out, except they will be able to dial Manhattan using either seven digits or 1 + 212 + seven digits. "On May 16, 1993, the change to 718 wilol become permanent. Customers who dial an incorrect area code will hear an announcement giving dialing instructions. These changes in dialing will not affect charges for telephone calls." The July "Hello" insert in my NYTel bill also announced to the public that area code 917 is introduced in New York City. The details are and I quote: "In recent years, the demand for telephone service has increased. To avoid a predicted shortage of telephone numbers, area code 917 has been introduced in the five boroughs of New York City to serve pagers, cellular telephones and certain other communications services in the 212 and 718 area codes. "July 1,1992, paging and cellular telephone companies will begin assigning telephone numbers with the area code 917 to NEW customers. Customers with EXISTING 212 and 718 pager and cellular numbers will be assigned new telephone numbers in the 917 area code over the next few years. "Please be aware that when dialing a number in the new 917 area code, you are not calling someone across the country. You are most likely calling someone with a pager or cellular telephone. "Charges for calling the 917 area code from 212 or 718 are still local calls. Charges from other areas also would not change."

This is a request for information about having it repaired. When I pick up the receiver I hear dial tone in the earpiece, so far, so good. But when I speak into the mouthpiece, I cannot hear my own voice in the earpiece. In other words, I can hear the caller, but the caller cannot hear me. I have checked the round microphone cartridge (on another phone), it works. So the problem is somewhere in the phone's internals. Also the paticular wall-jack and wiring is good, as other phones work with it. Can someone offer me any advice on how to get this phone working again? Is there a common (simple?) part that I could replace? Ideally, might someone know a way I could get this phone repaired in the Houston, Texas area? If I played the game AT&T's way, I would have to send the phone in, and they would send back a refurbished newer phone. Well, I want to keep and use this particular 2500 phone (sentimental attachment, I suppose). Please don't reply "call AT&T", I already did that. Now it is on to Plan B. Please send response via e-mail, and to anyone that may be able to help; thanks in advance. Gary Korenek (korenek@ficc.ferranti.com) Ferranti International Controls Corp.

I have two questions that salesmen can't seem to agree upon, and whose information always seems to be biased towards the particular model they are pushing at the time ... 1.) Are 3.0W units really going to buy me alot more compared to the compact 0.6W phones -- in regards to TX (and RX?) sound quality, battery life, max distance from the closest transceiver, or other issues I haven't thought of? 2.) Is there really a regulation that restricts 3.0W units to the "transportable" size? At our local AT&T center, a sales lady tried to tell me -- when I asked if she predicted even more compact 3W units in the near future -- that regulations prohibit the small single enclosure pocket sized phones from being more than 0.6W. Now I can believe that battery technology might limit futher size reductions of the more powerful transmitters, but what she told me makes no sense (but then many regulations make no sense). I ask because if 3W units are that much better and they aren't going to get smaller in the near future, then it's time for me to buy. Thanks for any response.

My handheld 0.6 watt unit works fine in a very populated urban area like Chicago which is saturated with cell sites. A year ago, my handheld worked fine in Coffeyville, KS and latched on to the cellular carrier in Tulsa, OK about sixty miles away. Not all work that well. The three watt units are mostly for automobiles. And yes, regulations say you can't have a three watt handheld since there is a risk with the antenna so close to your head that you might irradiate your brain cells, and become goofy like your Esteemed Moderator, whose battery hasn't taken a full charge in many years.

My guess is that Southern California will soon see 710 used as a prefix, as this is the standard intercept one gets when dialing 1+ or 0+ and any prefix.

I called my local telco business office which referred me to the Boston ISDN office. They sent me to a Network Consultant who admitted that he would be the person to carry out a Switched 56 work order, but that for me to get any substantive information I would have to talk to a marketing office. The marketing office has been a black hole. Any suggestions? I'm primarily interested in this service for use within eastern Massachusetts (508/617). Does it exist? How does it work?

Why are the letters "Q" and "Z" missing from the telephone keypad? And why do the letters start on the number 2 key?

Cheenne dcheenne@unlinfo.unl.edu [Moderator's Note: Telephone numbers do not usually begin with '1', and having the letters /ABC/ there would have effectively precluded them from being the starting letter in an exchange name, back when telco officially used words to identify central offices. In order to keep the zero available as a single digit way to reach the operator, letters were not used there either. Imagine life with no AVEnue, AUStin, BIShop, BOUlevard, CIRcle, CAThedral or COLumbus ... Since only eight digits are left, two letters had to be elimininated, with /QZ/ least likely to be needed.

It was later determined that his cordless phone (with weak nicads) had called the "911" number. Last month this same friend's cordless phone (a new one) had nicad problems. The phone could still receive calls, but any attempt to dial out resulted in "Thank you for using ATT ...". This is confusing to me. His default LD carrier is MCI. What could possibly cause the phone to call the ATT operator? Last week he replaced the nicads and the problem went away. Can either of these problems be explained? Thanks in advance.

In addition, Rochester Tel wants to expand the local calling areas for several communities receiving its services, the company said. The PSC must grant approval for the change, which would not affect rates on long distance calls made out of Rochester Tel's territory. A PSC spokeswoman declined to comment about Rochester Tel's plan, but she did say it would be reviewed thoroughly. Rochester Tel is seeking to change the way long distance toll rates are calculated, said spokeswoman Diana Melville. Currently, toll rates are set through a formula that pools the revenues of larger telephone companies such as Rochester Tel and smaller ones such as Ogden Telephone and Seneca Gorham Telephone. The formula was created so that all telephone companies charge the same rates, regardless of the size of their customer base or how efficiently they operate. However, Rochester Telephone believes the system forces it to charge higher rates, which means it contributes too much to the pool, Melville said. "We want to charge our customers the rates closer to what it costs for the company to provide the service," Melville said. Business customers would be billed the same rate for local service and long distance calls to exchanges within the Rochester Tel service territory (the Rochester LATA). Businesses would be charged 7.1 cents for the first three minutes of a call and two cents each additional minute, regardless of the time of day or distance of the call. Businesses now pay monthly rates for local measured service that are based on the time of day and duration of the call. Long distance calls within Rochester Tel's service territory are billed on distance, time of day, and duration. For some residential customers, local calling areas would be expanded to eliminate billing based on the distance, time or day, and duration of the call. Under the proposed plan, calls made between 8 am and 9 pm will be billed at 17 cents per minute. Calls made between 9:01 pm and 7:59 am and on weekends/holidays will be billed at 7.65 cents per minute -- a 55% discount over day rates. Rochester Tel also plans to offer residential customers two optional service plans to expand their local calling areas even further. Under one plan, customers can pay $5.95 per month to call communities that up until now have been long distance. Customers receive 60 minutes of calls after 5 pm and before 8 am weekdays, weekends, and holidays (9.9 cents per minute). If customers make more than 60 minutes of calls to those areas during off peak hours, they will be billed at 5.9 cents per minute. The second plan would cost customers $3.95 per month for 30 minutes of calls (13.2 cents per minute). If customers make over 30 minutes per calls, they will be billed at 7.65 cents per minute. Other proposals: Geneseo will now be able to call Avon numbers for free. For $5.95 per month, Geneseo customers will be able to make 60 minutes of calls at certain times to such places as Caledonia, Hemlock, Pavilion, and Perry. Leicester residents will now be able to call Perry residents for free. Using the above $5.95 plan, Leicester customers will be able to call Avon, Castile, Livonia, and Pavilion for less. ------------------------------ From: gavron@spades.aces.com (Ehud Gavron 602-570-2000 x. 2546) Subject: DMS-100 Peculiarity - HELP!!! Date: 18 Jul 92 20:20:00 GMT Reply-To: gavron@Spades.ACES.COM Organization: ACES Consulting Inc. I'm in the process of moving to a new location in rural Tucson AZ outskirts. US West was kind enough to give me two lines without realizing that they only had one pair going to the pole. 1/2 mile of "C-cable"* is on its way. Here's what really ticks me off though. I used to be on a 1AESS and now I'm on a DMS-100. My custom calling features are call-waiting** and speed-dial 30. HOWEVER, I find the following peculiarities: 1. If there is no call waiting call coming in and I flash the switchhook, I get a SECOND dialtone. However, I am unable to dial any number on it since at the 4th digit I get a fast busy signal. (It won't dial 2-digit speed-dialed calls either). 2. If I attempt to program speed dial via: [dial tone] 75# [confirm tone + dial tone] nnNPA-NXXX, wait then it fails (fast busy). If I do the same but leave off the pound: [dial tone] 75 and wait [confirm tone + dial tone] nnNPA-NXXX, wait then it works! (Number programmed) Number 2 is a nuisance, but as I rarely _program_ speed calling numbers, I could live with it. However, number 1 is a big hassle since I'm used to tapping the switchhook and redialing a number very rapidly. Now I have to hold it down and count One-Ringy-Dingy. Does anyone know: 1. WHY 2. WHY 3. WHY? * Does anyone know what C-cable is? What is it used for? What do I have now that is not a C-cable? **This feature ought to be mandatory for everyone I ever call ...

Biology PacBell sent me an mailing for 'open collar' workers in May. I guess they figured out from my having four phone lines that I was a work-at-home. In fact, I'm not, but the mailing promised me a free book if I would take a telemarketing call. Not being the type to pass up an offer like this, I called from work, not home (can't be too complacient) and they promptly connected me to a telemarketer. She took my address for the book (just got the book "The Work-At-Home Book", full of useful tips on how to use your cat as stapler, make extra filing space out of pots and pans, and making a postage meter a decorative item, but I digress), and went thru my past few months bills looking for services to pitch to me. She did sell me a local area calling plan for an unnamed area, but the thing I was really intrigued by was that I could have my very own PacBell sales person assigned to me. I think this is a win -- I get pretty tired of explaining to whoever I end up ordering from why I need 24 voice circuits delivered on T1 to a residence. But the best part was that I found out that you can now get 'Custom 800' on a residential line. Custom 800 is 800 service delivered 'on top' of an exiting line, rather than having a special '800' line. This sounded great, but it had to cost a mint, right (I'd costed out 800 service at previous employers to lower datacomm costs)? Nope -- I was informed that I could have it for $5/month, plus costs, and it could cover whatever service areas PacBell covered (I just got it for service area 1, since I don't know anyone in LA). Well, I thought, I must at least have to use a business line for it, right? Wrong -- this was specifically for residential service. I had to have it. For $60/year, I could impress the babes by saying "My number? 1-800-BIG-STUD" But it got better. One, I did get to pick my own number (and no, I'm not going to mention it here) and two, it was instant gratification, since the number was activated within about 15 minutes of my order. Well, I've had the number since May, and its been great. Why has it been great, you might ask? Well, its because I call my home answering machine alot from pay phones. I don't always have change, so I tend to use my calling card. And as most of us know, PacBell whacks you for $0.35 every time you do that. But with my 800 number, I just pay $0.185/minute prime time (less at night, when I do most of my calling), and they don't have a call setup charge. So, if I make 14 calls home a month from pay phones (and I do), its a wash versus my calling card costs. Of course, if I'm calling from downtown, I lose, but most of my calls would be about $0.25/minute milage (south bay to home). There are a few problems: they don't break down the 800 billing by call, just total minutes in a certain calling period. So, I don't get the numbers that called me. Thats a little irritating, since I can't dispute a bill. Also, you pay in advance for the service, but since that's only $5/month, its nothing on top of my total phone bill. So, if you want to impress the babes (or the dudes, depending on your polarity and preferences) or you call home alot, you might want to look into 800 service. Kenton A.

Both involved puzzling ringing either on the recording or to another phone. They didn't involve crazy conference calling or human intervention. First off, tonight a friend called us from the airport. No one was home to take the call, and he wanted to save his quarter to speak with a live person. So he hung up after the usual four rings, before the answering machine picked it up. Then he tried again later, just getting a busy signal for 45 minutes. He got through later when someone was home and learned why he couldn't get through. The connection wasn't broken. Instead the answering machine recorded about 45 minutes of a phone ringing on the other end. The pay phone didn't ring, just somewhere a phone was ringing and the answering machine recorded it. We couldn't figure it out. Then I started to think the switch in the central office was messed up somehow. I have no idea what kind of switch it is. The company is TDS - Waunakee Telephone Company in Wisconsin. Perhaps some reader is aware of this small telco and what equipment they use. I only read this Digest to learn about this sort of thing. So I ask you what could have been going on? By no means is this answering machine sophisticated, so it couldn't have dialed anyone. (Nor did the cat! :) Apparently this has happened once before recently. The second story involves a Centrex system at the university. My friend from the airport reported that in his office, he or his office mate would call someone and get their answering machine. If they hung up before the OGM was finished, the phone would ring soon to give them the answering machine and the last of the outgoing message. He offered this as a clue to the last mystery. It seemed to me to be unrelated, but it might be. The friend said the Centrex system was responsible for the ringbacks (not in those words). He thought it was too slow in detecting the fact he had hung up and would call him back to complete the connection. I think that's plausible, but I want to know what the readers of TELECOM Digest think about this mystery. What could or should explain the things we've observed?

Every new venture that phone companies are allowed to pursue means that old reliable finance cash cow, the regulated ratepayer, will have to fork over even more. And what will be the ultimate result? Your telephone dollars will buy even more of the drek and waste that litters every cable company in the land. How many more shopping channels can we support? How many more news operations? How many more movie channels? My local cable company (considered one of the best in the country) has over 50 "basic" channels and more often than not, there is nothing worthwhile to watch. This is a case where competition can actually have deleterious effects on an industry. The plethora of program producers are chasing after a limited number of dollars and spreading them thinly among themselves. This means that no one producer has the necessary funds to produce really quality entertainment. The result is mediocrity that makes former FCC Chairman, Newton Minnow's "Vast Wasteland" look like entertainment and information heaven. I have no love for any cable company, including mine. This is an industry crying for comeuppins. But the answer is not to water it down even more and to finance the project with your utility dollars. We are giving the green light to our nation's telcos to provide everything that has to do with information. Telco's will own the cable plant, switching centers, and microwave towers. They will provide the audiotex product (and control the content). They will provide the news. They will (with this decision) provide the video entertainment. After having just reviewed "The President's Analyst", I can just imagine what our society -- owned and operated by "TPC" -- will look like. Here it comes: The United Bell States of America.

It turns out that our local library has all the French phone books, including that for St.Pierre & Miquelon, so I went and looked. If I understand the French correctly, the telephone system works like this. France is divided into 100 "departments". For telephone purposes, these split into: Paris/Ile de France: departments 75, 77, 78, 91-95 Provincial: departments 01-19, 2A, 2B, 21-74, 76, 79-90 DOMs: departments 971 (Guadelope - country code 590), 972 (Guyana - country code 594), 973 (Martinique - country code 596), 974 (Reunion - country code 292). In addition, there are five TOMs: Mayotte (country code 269) New Caledonia (country code 687) Polynesia (country code 689) St.Pierre & Miquelon (country code 508) Wallis & Futuna (country code 681) [I don't know what DOM and TOM mean.] Paris and Provincial numbers are eight digits, and DOM and TOM numbers are 6 digits, not beginning with a 1 (I don't know about 0). Provincial numbers beginning with 93 are in Monaco, and 628 in Andorra. All numbers on St.Pierre begin 412, 413, 414, or 415, and on Miquelon 416. Dialling instructions depend on where you are calling from and to. A tilde indicates a second dialtone, a # indicates a digit. Within mainland France, you dial ######## for the same system (Paris or Provincial, or 16~######## for the other). To dial a DOM or a TOM, you dial 19~CCC######, and to dial a foreign country you dial 19~CCCAAA#######, where CCC is the country code, and AAA the area code (if any). To get operator assistance or directory enquiries, you dial 19~33CCC, except that the country codes 1 and 7 need to be followed by an additional 1. From a DOM or a TOM, the codes are: Same DOM/TOM: ###### Paris 16~1######## Provincial 16~######## DOM/TOM 19~CCC###### Foreign 19~CCCAAA####### except that since all Guadelope numbers begin 2, 8, or 9, and all Martinique numbers being 5, 6, or 7, there is interdialing between the two (i.e. just dial the 6 figure number). Operator assistance for foreign countries from DOMs and from St.Pierre and Miquelon (the library didn't have the other four books) varies: Guadelope 10 Guyana 19~594CCC Martinique 19~596CCC Reunion 19~262CCC for operator 19~26212CCC for directory St.Pierre & Miquelon 10 Finally, there are two special dialing instructions. From Guadelope, numbers in St.Barthelems and St.Martin (both French and Dutch parts) of the form 3##### can be dialled direct.

Considering that EFF took a blind-side broadside from oudda-da-bloo, I think Mike Godwin's return salvo was both justified and, under the circumstances, restrained. Nor do I see anything in Mike Godwin's comment from CW cited above that is shrill. Those who have followed federal actions over the past two years have every reason to be suspicious of LE's motives and methods. The initially highly-publicized Sun Devil produced little of significance and resulted in litigation against federal and civil participants for their efforts against Steve Jackson Games; The prosecution dropped its case against Craig Neidorf before it had even concluded its opening arguments; and regardless of what one thinks of Len Rose's actions, there is considerable room for the judgment that he was treated unjustly and unfairly. One need only read Bill Cook's published work and read the transcripts in the Neidorf trial (avail- able in CuD archives at ftp.eff.org) to realize that Mike's above- cited comment should be taken seriously. The indictment of the five MOD people, while alleging some serious charges, also raises some issues that justify Mike's statement. There is also strong justification for objecting to the sentences given "hackers," for questioning the competency of some law enforcement officials in the 1990 cases, and for concern over the implications of the investigative and prosecutorial methods used against alleged "hackers." Expressing such concerns is an attempt to preserve truth and accurracy and hardly strikes me as "shrill" or "sensationalist." It certainly is both more honorable and more honest than to attack the messenger with ad hominems rather than address the message.

I will now contact {Computerworld} and seek a retraction. I do not for a moment believe that the government has set out to frame anyone. What I told {Computerworld} was that, with regard to the erasure of data at Learning Link, in which individuals purporting to be two of the defendants called up and claimed credit for the vandalism, it was possible that someone other than the named defendants had made the call. I explicitly stated to *every* member of the press that we had no reason to believe at this time that the government had done anything wrong in pursuing these indictments. Other press reports, so far, have been accurate. This make me furious. It should be noted that we are not handling these individuals' defense, so attributing their defense strategy to us is a mistake. I ask Sam Israelit and all others who read the {Computerworld} article to accept my statement that at no time did I suggest, to {Computerworld} or anyone else, that the government had framed anyone.

First of all, it is simply untrue that there is no quality on cable, though by use of the word "entertainment" it's not clear what Higdon wants. Just a few examples: C-SPAN C-SPAN 2 Bravo Arts and Entertainment HBO original movies CNN CNN Headline news. Second, dial-up access to video services means that far more niche markets can be satisfied, since there are far more channels available on a fiber optic pipe into one's home, than on a cable with fixed frequency allocations. Moreover, one doesn't have to modify the subscriber equipment to add channels; just dial another number. Third, fiber optic pipes into our homes will make data services, highly sophisticated telephone services, interactive ordering and many other thing available at low cost. Some who want to grab some of these dollars, such as newspapers and others, also oppose phone company entry for naked economic reasons. But such opposition is not in the public interest since they aren't as technologically ready, nor have they the market base or cost structure to provide such services as cheaply as the phone companies can. Finally, cross subsidization can be trivially handled by the state PUCs with proper rules and accounting procedures. There's evidence this works -- look at the very low cost of Long Distance calls compared to local calls in many cases, due to the removal of cross-subsidization by the regulatory process. Thus the opponents' biggest propaganda objection is just plain silly, and only the gullible will fall for it.

Afterall Mr. Higdon, weren't you recently complaining about not being able to receive ISDN at home? However, this exacerbates the problems opened up with the previous ruling allowing RBOCs to provide content. Let the telco's compete with the cableco's and eliminate the "natural monopoly", make them fight for our dollars by competing with each other in quality and services in delivery (medium). But by god, keep both of them out of creating the message, for it is far too easy and tempting to use one to gain control of the other. And I agree with Higdon here, without regulating this, the US will certainly become the U.B.S.A (or U.C.S.A). As for the "Vast Wasteland" of media sub-mediocrity coming out of even more choices, I think the real point to keep in mind is that video on demand is an existing market that makes it very clear, even to those who have no vision, of the potential that can come from bringing high bandwidth home. It's only the tip of the iceberg, as Gibson, et al have popularized. Now that McGowan is gone, who'll slay the reawoken Goliath?

Most machines can maintain very detailed STATUS, and can report them via Special Study reports. If Usage Sensitive Service is applied, the switch will bill each call, so it could be researched via billing checks. If the line is not on Special Study, and USS Billing is not being applied, no record is kept of a local call. If requested in advance, the line can be placed on special study, Hot Number status, or Annoyance Call Monitor. Then the information desired could be retrieved later. Disclaimer: I speak GTD-5ese. People speaking 5ESSese or DMSese would call these things different names, but the functionality is equivalent.

Entirely correct; there is probably no way to trace the calls that were placed to your home in the past, if they were local calls. However, you still have an alternative. On a line-by-line basis, the telco can keep records of all calls going TO your telephone. Most modern switches will have some form of 'annoyance call' trace, such that when your CO receives a call for your line, it can generate a record of where that call came from. If it came in on a trunk, that may be all that they know. However, if they set up an annoyance call trace for any call going TO your line in all the CO's in your area, then any time anyone calls you from one of those CO's, it will generate a record. If you expect this pattern of robbery to continue, I would suggest that you push this matter with the sheriff and telephone company. If, as you claim, they have a modern switching system, then they can perform this sort of trace. It's a bit of trouble for them, but that's why the trace feature is there.

I assumed responsibility for any number I recognized as well as those I did not recognize from times of day when I was likely in my office and could have used the phone. I did a name and address check on those I did not recognize from times I knew I could not have been on the phone. *Lots* of calls had been made to such places as 'IBT Company Vehicle Repair Depot' and 'IBT Co., 65 East Congress Parkway' (the CO building itself!). I called back and pointed out that obviously some technicians were using my pair to make all their calls and I would not pay.

Teacher, call on me! I know the answer! There are several valid reasons for a single calling card to have calls from distant origins: 1) the calling card is shared by several people, such as a family. Just as the home phone number is shared by the family, the calling card is used by the husband at the office, the kids at college, etc. Or a small business has its people in the field using the main number to bill back calls. Perhaps accounts can be flagged as shared/not shared. 2) the origin of the phone calls is not always accurate. As explained previously in TELECOM in great detail, many alternate carriers have a POP (Point of Presence) that may not be in your same county, or state. Calls from a few miles away may appear to have originated from different states. There are commercials for various credit cards where the card holder gets a call from security verifying some unusual activity on their account and preventing fraud. Similarly, I think that calling card fraud can be detected not by origin but usage pattern analysys. Sudden changes such as many overseas calls or very long calls should warrant verification from the account owner. I do not agree to service denial/shutoff based on this information because there are too many cases of TELECOM readers having valid accounts terminated due to misinterpretation of account use. jeffrey jonas jeffj@synsys.uucp ------------------------------ From: nagle@netcom.com (John Nagle) Subject: Re: Locating Cellular Information Date: Sat, 18 Jul 92 19:29:30 GMT Organization: Netcom - Online Communication Services (408 241-9760 guest) pwan@skidmore.EDU (peter wan) writes: > I am looking for general and technical information regarding cellular > systems and cellular technology.

Any suggestions are welcomed via email. I suggest "Digital Cellular Radio" (the book) for an unique view of the current problems and future directions of cellular technology. Don't have the author's name handy, though. Check Books In Print. This is a fun book to read, and it focuses on the issues of scaling up cellular systems to large numbers of users. Propagation of UHF signals in cities in covered in detail. The advantages of spread-spectrum are explored. Compression is discussed. Power control is analyzed. How the designers of the existing system screwed up by choosing Chicago as a testbed is explained. Reading this book convinced me that cellular systems have to go spread spectrum eventually. So I bought some Qualicomm stock. (I think, though, the existing cellular providers are a little afraid of spread spectrum, because there's no fundamental reason that there has to be only one cellular company in a band with spread spectrum systems. It could break the duopoly. Eventually it probably will.)

This reminds me of a feature on some of the Motorola bag phones that I consider to be just a marketing gimmick: a .6W/3W switch. The sales people will tell you that when you are running the bag phone off of batteries, it is a good idea to switch it to .6W to extend the battery life; when you have it plugged into the cigarette lighter in your car, switch it to 3W for best reception. Of course, astute TELECOM Digest readers will note that the phone doesn't always transmit at the maximum power level, but is instead commanded by the base station to transmit at the lowest level that's necessary for a good signal. So, if you're near a cell, and only need 200mW to get a good signal, your phone only transmits with 200mW, regardless of whether you have a 600mW or 3W model (this is primarily so that the cell size can be scaled -- not to conserve battery capacity, although that is a nice side effect). In any event, the only thing that the 600mW setting of the bag-phone switch accomplishes is cutting off your calls when they need more than 600mW to get through -- they don't save any battery capacity otherwise. Since I can't imagine that even under battery power you'd rather have your calls cut off when they need more than 600mW just so you can 'save your batteries,' I conclude that this is just a marketing gimmick.

One of the early studies which found a correlation between childhood leukemia and electromagnetic field emissions was done on some suburban development -- nearly all the leukemia cases happened in houses that were immediately near the step-down transformer on the utility poles in the area. For that neighborhood, the step-down transformers were located on the corners of street intersection. Hence it's not a case of different income classes or any of the other factors suggested by other posters. One testimony I heard (all in well-reasoned tones by various scientists who were discussing EMF at a public hearing about a water-supply construction project in my neighborhood) is that it's clear that EMF can cause cell damage -- the question is what frequencies and what power levels cause the problems. There may be "windows", similiar to the atmospheric window which allows visible light to penetrate but blocks out (well, it used to anyway, before the ozone hole) ultraviolet rays and other stuff outside the frequency range between infrared and ultraviolet. One theory is that EMF exposure within the "windows", i.e. of a certain frequency for at least a certain time, can cause damage to the body but other frequencies (or the same frequencies but without sufficient exposure) will not cause problems. The microwave industry (remember, microwaves are non-ionizing radiation too) has a goodly amount of occupational diseases, especially glaucoma in people who have to work on antennas (the name Samuel Yannon comes to mind, who had to sue his employers heavily in order to have his glaucoma recognized as work-related). Of course, we're talking huge differences between the power levels at a TV repeater station or a long distance phone link and the piddling 600 milliwatts of a cellular phone. > There is an extremely well-written (truly delightful to read despite > the subject matter) book on this subject by Paul Brodeur. One of the topics examined by Brodeur was a street in Connecticut where single family homes were located next to a high-powered electrical substation (we're talking complete with giant transformers and the like). Leukemia and brain tumors seemed to be the order of the day for the residents on that street, as well as the residents along the lines feeding the substation. Again, we're talking EMF levels orders of magnitude higher than cellular phone output. I've read parts of Brodeur's series in the {New Yorker}, (the book is called "Currents of Death") and he does document all his sources well enough for any other interested parties to verify his conclusions.

Observers have said the fees could drive up telephone line costs to information services companies by as much as 300 percent, some or all of which online service members would likely bear. CompuServe again needs your help in fighting any proposed cost increase so that online services can grow and remain affordable. The ramifications of the FCC's possible action is explained online (GO FCC). This area is free of connect charges. CompuServe asks that you send a letter to the FCC in opposition to modem fees and also to write to certain U.S.Senators to encourage legislation that would require the FCC to allow CompuServe and other information services companies to use new and more efficient technologies without being subjected to higher telephone line access charges. Also, please copy Congressman Edward Markey of Massachusetts, Chairman of the House Telecommunications Subcommittee. In 1987, a similar letter writing campaign by online services users helped prevent increased access charges from being implemented. The GO FCC area lists the names and address of FCC commissioners and U.S. Senators to whom you should write. Or, CompuServe will soon make available an FCCgram you can send electronically for 29 cents to the FCC and Senators. (Composing online is free.) A sample message is provided.

They don't have to share the same number. One of them could be assigned a special calling card number (sometimes called a fictitious number) that would be billed on the same account. Some telephone companies and long distance carriers may be reluctant to do this because there are a limited number of possible fictitious numbers, and some residential service representatives may not have been trained how to set up this kind of calling card. Similarly, another family member (such as a child away at university) could be given his or her own calling card with a separate number, but billed to the family telephone account. If you have problems requesting a separate calling card number for yourself or your spouse, explain that Nigel Allen told you that the separate number would be a good idea, and that he said to mention his name in case the business office was reluctant to process the request.

The idea as I understand it is: You ring into one modem on one machine. That machine accepts your details, and then hangs up the modem and tells a completely different machine to call you back on another modem which is in a modem pool of outgoing only modems. We know about dialback modems, but it seems they are not as secure as we'd like. I'm sure something like I describe must exist, but we don't know what it is called or where to get it. Please help.

We all know that if the same modem is used to accept incoming calls and then dial back to the user there is always the possibility a hacker will simply sit on the line after the modem disconnects, wait until it goes off hook, simulate dial tone and seize the connection, thus defeating the security of calling back to only registered numbers. Likewise, hackers have gone so far as to find out the bank of numbers used for outcalls, dialed into them and sat there waiting for a modem to go off hook to make a call then fraudulently seized the line in the same way. The same line can be used in both directions in a secure and effective way to defeat hackers: simply have the line equipped with three-way calling from telco (not call waiting!) and make a hook flash the first part of any outgoing dialing string. Here is what will happen: The modem goes off hook and does ADTD! (or whatever is used to flash the hook) followed by a pause and the number to be dialed. If no one is holding the line on the other end waiting for the modem to go off hook, then the switch hook will be ignored and a fresh dial tone brought up -- there is no basis for a three way call. On the other hand, if someone *is* sitting there waiting to play tricks, then the hook flash will put that person on hold and provide fresh dial tone for a 'three-way' call ... of course, the calls will never get conferenced together, much to the hacker's chagrin ... and he can sit there on hold as long as he wants while the modem scoots around him on the three-way side to reach the registered user at the authorized number, using the 'consultation' feature of three-way calling rather than the 'conference' feature. Without three-way calling from telco on the line, flashing the hook will do nothing but put the call back where it was; but with three-way and a hook flash as the first command in every dialing string, never the hacker and outcalling modem shall meet. So forget about the two modems, one machine telling the other one what to do, etc. It isn't necessary. Just use existing features in the CO to hustle your hacker nemesis out of the way should he be parked there waiting for you. Can anyone tell me precisely why this would not be foolproof?

The time-of-day reporting system you describe is an outboard box, completely independent of the telephone switching system. You call a number, you're connected to this box, it states the time, and that's it. In the GTD5, the time-of-day is synchronized to the network clocking signal. This signal, which is used to clock all PCM traffic through the switch, is typically obtained from an External Clock Synchronization Source (a T1 span to an adjacent higher-order office). All the CO's in a network are, in theory, synchronized to each other, with the master timing source coming from the Grand Master Of Clocks in Hillsboro (?), Missouri. If anyone knows more about this Grandaddy of clocks, I'd be interested to hear about it. I believe that MCI and the US Navy also operate similar 'Master Clocks'. The time-of-day, as you state, is used for billing and other purposes. It is accurate to within +/- 15 seconds per day. But, it has no relation to the recorded announcement.

But don't forget the infinite series that results: You go off-hook to listen for dial-tone. You hear steady tone for a second or two, indicating that at the time you went off-hook, there were no messages waiting. You go back on-hook, secure in the knowlege that you don't have to call anybody back right now ... But while you were off-hook checking, somebody called, and by the time you were finished checking, and back on-hook, they had been forwarded to the telco voice mail system (because your line was busy). They leave a message, but you were finished checking by the time they were finished recording it. You must pick up again, after a minute or so, to see if anybody left a message while you were checking for messages. And of course, the same thing could happen during your next check-for-messages! The light on your answering machine, or on your telephone if it could be activated by the telco's voice mail service, would seem to be a better idea. You can check it (by looking at it) without missing another call in the process. To use their service correctly, you must go off-hook at least once after every conversation, to see if a call arrived while your were busy. This means that for every call you place or receive, you must go off-hook at least two times -- once to make the call itself, and a second time, to see if you missed a call while you were busy. This approximately doubles the number of dial-tone registers required to serve your community. That expense, of course, is partially offset by the service charge imposed on the users of their voice mail service. It is also partially imposed on all users of their basic telephone service. I don't consider that an advantage. Dave Levenson Internet: dave@westmark.com Westmark, Inc.

Anyone interested should read the original. Now can we stop calling each other names and get back to phone phun?

Don't know, but if it's just BNR's, won't the lawyers be upset that you didn't use the (trademark/servicemark) symbol? For years, AT&T had several "corporate" networks, each with it's own purpose, funding and connectivity. On the manufacturing/research side, there was "CORNET", a "Hardware-defined network" using seven-digit access numbers to reach almost anywhere. The "NXX" digits usually defined a location, and the last four digits typically matched the extension. In some cases, an off-premises extension would be used to extend a number to a remote location. This was often used to provide CORNET lines to Western Electric CO installations, since installers were not allowed to use the CO telephones (One Bell System, ya' know?). Most TELCos also had their own "network", and so did the Operations part of the Long Distance service. But you couldn't call between them. Several other large companies used versions of CORNET long before 1984 changed the business. I don't believe any are left, since things like SDN (Software Defined Network) are more flexible, and have better real-time controls and data collection. Why, you might wonder, would "The Phone Company" want a private network when they OWNED the network? It's simple -- CORNET allowed AT&T to easily restrict most telephones from making non-business calls. This prevented (they say) lots of abuse, at least by the non-management employees. Having "9" unblocked on your telephone was a "power" symbol at many factories. Since most telephones factory telephones were black, dial-pulse beauties, a common "lock" was a physical lock in the "9" hole of the dial, preventing "9" or "0" calls. "8" usually got you to CORNET, others were internal. As usual, the legal/regulatory area also made itself felt. CORNET could be justified because it prevented those abuses that might have otherwise required lots of record-keeping and justification of every call made by AT&T -- just to be sure AT&T wasn't "giving away" personal calls as a benefit. And, of course, it also allowed AT&T to concentrate on providing GREAT service to it's paying customers, and fixing the CORNET problems when there was time available ...

She waited about half an hour before finally giving up. As the guy who designed that seatback phone for GTE, I think I can answer this for you. (GTE "restructured" me out of the company a few years ago, and I'm now employed by "the other" ATG phone carrier, In-Flight Phone Corp. Look for us on USAir 757s.) (But I'm on the General Aviation side, not Commercial, so if it eats your dime, don't flame _me_ :-) The aircraft itself has a maximum capacity of (4) phone calls. This is a limitation imposed by the amount of radio equipment carried onboard. It takes about two lineal feet of shelf space in the equipment bay to handle those four calls. They may decide to double-install some high volume aircraft, but they didn't do so while I was there. Real estate in the equipment bay is SCARCE. There are four cabin trunks available to connect handsets to the onboard switching computer (called the ACU). If all these trunks are in use, the green LED on your handset will not illuminate -- in fact the handset is not even powered up at this point. (The cordless GTE system can have as many as eight phones in the cabin, and they can all connect to the ACU. But you can still only have four radios -- four calls per aircraft.) When the green LED comes on, this indicates that a cabin trunk is available. You can seize this trunk by running your credit card through the handset. If 20 people all pick up their handsets at the same time, they will all get green lights. The first four to swipe their cards through will connect to the ACU, and everybody else's LEDs will go out. When one of the four hangs up (in the holder, not just by pressing NEWCALL) all 16 of those LEDs come back on and you can all race for the trunk. If you listen to the handset while waiting for the LED to come on, you'll hear a "beep-beep-beep-beep" signal. When the beeps stop, your LED is on! Once you are connected to the ACU your credit card is checked and (if it's a valid card) you are issued either a dialtone or a message indicating "all lines busy." The ALB message means that your ACU is unable to open a channel to the ground station. This could be because the ground station's 31 (max) channels are all in use, or because your aircraft has fewer than four radios installed, and those that are installed are in use. Three years ago, very few ground stations were fully stuffed out to 31 channels. > On a side note, I'd be interested in seeing a study showing > how much extra Airfone revenue is generated for the airlines when > there are delays versus flights that are on time (why be on time when > you can make extra money by being late?). I only know that call volume went up a _lot_ when there was a weather problem. I'm sure that made (makes!) certain non-travelling people very happy! :-) And yes, the airline gets a cut of the call revenue.

Oh, I'm used to this kind of nonsense from AT&T people. The last time I took the trouble of memorializing a bell-shaped person's name was when I was doing a market survey in preparation for a new switch at the Empire State Building, to replace an old tired Horizon-advanced. When I explained to our marketing person that I wanted switch diagnostics, including trunk group busy peg counts (we were grossly over-trunked, typical for a NY Tel-engineered leased PBX), she replied, "What's a peg count?" She was lost by the time we got to "busy studies." I never got specs on whatever small-to-medium size switch AT&T was trying to push on (presumably) inexperienced business customers. However, after they later left us with no service for three days (power supply failure, and they hadn't backed up the configuration tapes in over three years) I wouldn't have specified AT&T product anyway. > Let me ask, do any of the AT&T readers here become embarrassed by > some of the stupid things their co-workers say to or pass off on the > public? PAT] What about when AT&T announced that they were discontinuing the System 85, and then followed it up with a denial that that would ever happen? One of my former City of New York co-workers has copies of both releases, right from the source. The trade media has been suggesting for some time (when they don't fall for phony press releases) that AT&T is getting out of the interconnect business. Could the horrendous service and inevitable hostile escalation be because they're already accepted that fate, or is it a symptom of incompetent management? Perhaps it may be more topical instead of trading "stupid AT&T jokes" to ask, "what smart business does AT&T conduct that makes their incompetence at least tolerable?"

But the only reasons I respond to your post: > Third, fiber optic pipes into our homes will make data services, > highly sophisticated telephone services, interactive ordering and many > other thing available at low cost. Ah, yes. The promise of fiber. This is, of course, what the telcos wave in front of the bright-eyed masses when it wants to monopolize and control potentially money making businesses. Cable companies already have interactive ordering if you are willing to pay. If and when telcos find it advantageous to "wire" neighborhoods with fiber, it will be because they have a definite profitable motive. "Other" uses that may interest you will probably be priced out of existence. Please try to keep your feet on the ground and remember that if the telcos set up broadband data highways it will be for the purpose of selling you their own data services (which they alone control and originate), not so that you may communicate with others of your own choosing. > But such opposition is not in the public interest since they aren't > as technologically ready, nor have they the market base or cost > structure to provide such services as cheaply as the phone companies > can. And why can the phone companies do this so cheaply? There is no magic here; there is no "in place" plant (regarding fiber) that could be efficiently utilized. This is the old shell game regarding the telcos' vast capital reservoir: the regulated ratebase. But apparently you don't believe this: > Finally, cross subsidization can be trivially handled by the state > PUCs with proper rules and accounting procedures.

Thus the opponents' > biggest propaganda objection is just plain silly, and only the > gullible will fall for it. It would seem that you have not looked very deeply into this topic. Such naivete and simplification could only be the result of ignorance. The cost of long distance calls has nothing to do with anything; they are handled by separate companies from the telcos. In the case of LD handled by the telcos themselves, I invite you to examine California's intraLATA pricing structure. But as to other matters, telcos REGULARLY cross subsidize services to the detriment of competition. How do you suppose that Pac*Bell, for instance, can offer "The Message Center" for less than the cost of the special features alone required to support it? Magic? Voodoo? You bet it is. And it appears that you have fallen for the old "Arms Length" eyewash all the way. Perhaps before you continue to dismiss my diatribes with a wave of the hand, you might (as I have) dig a little into the industry and speak to some of the independent providers. And then you might look at some of the real figures and tariffs rather than parroting the RBOC handouts. If you are really interested in facts rather than fluff and propaganda, you might find out what some of the independents are REALLY worried about. So perhaps you can tell us just exactly how the telcos will install new equipment and technolgy over the next several decades so much more cheaply than anyone else? Perhaps you can tell us how the telcos pull money out of thin air without tapping the ratebase? Perhaps you can tell us about all the advantages of having major amounts of information originate from one source? Inquiring minds do indeed want to know. John Higdon | P. O.

Levine > I don't fear telco monopolies as much as some seem to, and despite > your refutation of the LD carrier example, the principle is > unchanged -- PUCs can easily prevent cross-subsidisation. I fear you have an exaggerated idea of both the technical skill and the political muscle of most state PUCs. Preventing cross-subsidy is a very tricky business. For example, how do you allocate costs when a regulated and non-regulated operation share a facility? By floor space? Business volume? What if the two operations share a power system, the supply is very expensive because it's super reliable and non-interruptable, the non-regulated part doesn't really need that fancy a supply, but telco says it was easier (due to floor space limits or economies of scale) to get one big supply than two smaller ones. Or when they share repairmen? Or any of a thousand other things. A skilled team of accountants could eventually sort all this stuff out, but in nearly all cases regulation seems to consist of the PUC saying "Are you guys cross-subsidizing?" and telco saying "Nope, not us." The PUC in principle needs to audit every shared facility and every sale or transfer between the regulated and non-regulated side, and that is a tremendous amount of work. There's also the issue of whether regulated facilities are offered in a non-discriminatory way to all competitors, a separate and in some cases more important issue than cross-subsidy. For an example, voice mail is supposed to be a competitive business. Everyone agrees that Pac Bell's offering is junk. So where are the higher quality competitive offerings? According to lots of previous telecom messages, Pac Bell has made it extremely hard to get forward on no answer and stutter dialtone control, the two features that competitive voicemail needs. Somehow, they're only available in the COs where Pac Bell voicemail is needed, or they need special expensive interoffice trunks into every CO where there is a subscriber, or some such thing. And this doesn't even begin to address the question of whether the features are overpriced to kill the competition. Here in Massachusetts, telco offers voice mail (at $83/year, not exactly cheap) and you can't even order the separate features yet. This is competition? Local phone companies should be in the phone business. They should be busy providing CLASS* and nationally interoperable ISDN and inexpensive intra-lata packet nets. Instead they're doing cruddy voicemail and cruddier Minitel because they think there's more money in unregulated businesses where they can jack their prices up without limit, once they get rid of those pesky competitors. > Finally, cross subsidization can be trivially handled by the state > PUCs with proper rules and accounting procedures. There's evidence > this works -- look at the very low cost of Long Distance calls > compared to local calls in many cases, due to the removal of > cross-subsidization by the regulatory process. That's not a very good analogy -- there's a lot more than two long distance companies, and a long distance company doesn't have to run a wire to your house to sign you up as a customer. Furthermore, you'll note that local telcos are completely forbidden from competing in the long distance market so the subsidy issue is moot -- any subsidy would subsidize all long distance companies equally. If you look at the actual experience of local telcos in competitive markets, the experience is pretty awful. In places where telcos offer voice mail, for example, they do their best to bundle features and make them hard to order so that competitive voice mail systems don't stand a chance. Around here, you can't even order forward on no answer and remotely controlled stutter dialtone, so there's no competition at all for telco's voice mail other than to note that for what they charge you could buy and throw away an answering machine every 10 months or so (and it wouldn't mysteriously lose a week's worth of messages every now and then, either.) The local telco here is also offering a relabelled and rather expensive Minitel product with their "added value" being a yellow pages data base. Probably it'll lose money and fail like their earlier overpriced and underperforming on line service front end did (it ran at 1200 bps, no matter how fast your modem was,) the ratepayers will eat the loss, and telco will once again whine that the problem was overregulation, and they won't face up to the fact that the product was junk. In reality, I expect that what will really happen with cable is that the telcos will end up buying the cable companies in order to kill the only plausible source of dial tone competition.

I think St. Pierre & Miquelon has been upgraded recently from TOM to DOM, as part of a fishing dispute with Canada over the Grand banks. ------------------------------ From: wtho@ciba-geigy.ch (Tom Hofmann) Subject: Re: St.Pierre and Miquelon Organization: Ciba-Geigy Ltd., Basel, Switzerland Date: Mon, 20 Jul 1992 07:02:47 GMT In article clive@x.co.uk (Clive Feather) writes: >[I don't know what DOM and TOM mean.] DOM = Departement outre mer (being considered part of the French republic) TOM = Territoire outre mer (not being considered part of the French republic) > Within mainland France, you dial ######## for the same system (Paris > or Provincial, or 16~######## for the other).

STOP. 10BASE-T is not suitable for residential use, because it emits a boatload of EMI. (10BASE-T systems don't meet FCC class B.) If you operate a 10BASE-T network, there's a good chance your TV will be useless, and your neighbors' sets might also be impacted. FCC rules say that it's your responsibility to limit EMI, so you could find yourself forbidden to operate this network. I addressed this problem by running a 10BASE-2 COAX cable throughout my house. I also ran three-pair cable to each of 52 boxes, where I'm mounting two-jack outlets. All cables are "home-runned", i.e., everything connects directly to the wire closet where I have a panel of punchdown blocks. I figure you can't have too much copper in a house.

Hear! Hear! However, consider this: in today's climate of screwy regulation and de-regulation it would not be surprising at all to see the government on the one hand allowing the telcos entry into the information providing business and on the other allowing them to jack up rates to competitors. The telcos (RBOCs and independents) have always had a hand-in-glove relationship with the Feds and all those BBSes from Compu$erve on down make them just a little nervous. What better way to "institutionalize" the information that the public receives than to concentrate it in the hands of a highly-controllable monopoly? IMHO, the Bells are not the only ones that would like to see the BBSes bite the dust. I am sure the FBI for one is just a little tired of the chatter that goes on UNCONTROLLED every day on the thousands upon thousands of maverick computer systems. Look what damage just a few FAX machines did to the PR of the Chinese government. The Federal government has a serious "problem" here, and juggling the rate structure of the means of transmission could be a most effective tool in keeping the citizens in line. During a recent investigation to which I was a party, an FBI agent, after being told about USENET and the Internet, exclaimed, "You mean anyone can say anything he wants and there is no one controlling what goes out?" Without minimizing or excusing any crimes that might have been committed in the recent "MOD hacker" case, it is useful to note what a big deal the government has made about the fact that the investigation depended heavily upon "wiretaps" and that, fortunately in this case, all of the circuits monitored were analog. In other words, it appears that the inordinate hoopla surrounding this matter is designed to drum up support for the FBI-proposed legislation governing the tapability of digital networks. As telecom-knowledgable citizens we need to be aware not only of the "facts" of regulation or proposed regulation, but also of some of the motivation. On one of the "modem tax" go-rounds of times past, many on this and other forums offered a lot of justification why the telcos could and should charge users of modems more for telephone service than voice users. It was all bunk and those making such assertions were probably naive. But this is what we need to guard against: the playing into the hands of the manipulators. If there are massive changes to rate structures proposed, examine every aspect. Who will pay? Why? Who will benefit? Why? Who will be hurt the most? WHY? Social manipulation and (I really hate to use the word) oppression come gradually and with stealth. No one says, "We are now going to control the information you have access to." It is done through "well-meaning", but carefully plotted, relatively minor changes. You can bet that when and if there ever really IS a "modem tax", the public will have been pre-sold on its "necessity". Those not affected will not care; those affected will have been indoctrinated with all of the justifications. BTW, anyone out there still want to call me a "right-wing" radical? :-) John Higdon | P.

But then they call using BOTH numbers, ya' know ... There is one other thing that will work (for awhile), and is cheap and universally available. Just inform your selected callers (once you have Caller-ID available) that when calling from other than their normal telephone, they should call TWICE within a short period -- your short-term memory (or some device) will recognize the repeated number and answer the telephone. If that's too much trouble for the caller, then you probably didn't want to talk to them anyway; your time's valuable. You'll want to tell the local police, your bank, etc. as well.

(It won't dial 2-digit > speed-dialed calls either). While I can't speak for BNR/NTI, I believe the DMS started life as a PBX -- at least that seems to explain a lot of non-obvious interactions. Anyway, a 1A ESS(tm) switch will only give dial tone when you are allowed to make a call -- if you aren't allowed to "flash" during a part of the call, you get non-flash timing and treatment. This saves switch resources (a concern back in the 60's and 70's), and allowed all lines without "features" to act (mostly) the way they did with X-bar/SXS switches. Like you, customers complained 20 years ago when that new-fangled #1 ESS acted differently than their "old" switch. On the other hand, the DMS always allows you to make a call (at least to 911, I believe), so it first handles the flash -- and then sends invalid calls to "Reorder (fast busy)". If you don't have three-way calling on the DMS, almost anything is invalid after a non-call-waiting flash. But almost any "bug" can be a feature -- you can dial "*70 - disable call waiting" on incoming calls, assuming you are allowed to dial it on outgoing calls. > 2. If I attempt to program speed dial via: > [dial tone] 75# [confirm tone + dial tone] nnNPA-NXXX, > wait then it fails (fast busy). > If I do the same but leave off the pound: > [dial tone] 75 and wait [confirm tone + dial tone] > nnNPA-NXXX, wait then it works! (Number programmed) You might try "*75" or "1175". The 1A ESS switch usually uses "#" to stop timing for more digits from a non-Centrex telephone. The DMS is somewhat more selective, but US West might be able to change "#" to an allowed digit after a "service code" like "75". In fact, only a few of the "7x" codes are grandfathered to operate without a leading "#" or "11" -- newer feature codes conflict with speed call digits, etc. > Number 2 is a nuisance, but as I rarely _program_ speed > calling numbers, I could live with it.

ISDN phones don't use "flash", so you get immediate dial tone. Expensive, maybe, but we all have to trade-off cost vs. "hassles". You could always ask US West for the areas still served by your preferred switch ... > **This feature ought to be mandatory for everyone I ever call ... Maybe -- but I almost NEVER interrupt my current call to answer it. Do you really prefer "audible ring" to "busy tone"? Of course, the the 1A ESS "click" is a perfect excuse to end a bothersome call. With the DMS, callers just have to take your word that there's another call waiting.

PAT] I have always considered phone numbers like "VIllage 2-3629" an anachronism. Two questions: I have always seen such phone numbers with only the first two digits serving as the mnemonic or CO identifier. When did the phone company use three digits? And when was this practice officially abolished? [Moderator's Note: Prior to automatic service, telephone exchanges were known by names, followed by one, two, three or four digits. In a few rare cases there were five digits. The exchange names were chosen based on several things: their geographic location, ie. Chicago's Wabash and Franklin were on those streets; a neighborhood (Hyde Park and Lakeview); a famous person ([Clarence] Buckingham, [Mayor Carter] Harrison); or other factors. In small towns with one exchange, the CO was frequently just the name of the town. The first exchange in Chicago in 1878 was simply 'central' (as in central office), and over the years it metamorphosed into Central, CENtral, CEntral-6, CE-6 and for the past 30 years or so, 236. As automatic dialing was phased in and manual service phased out (we here began converting to dial service in 1939; the war halted further conversion from 1942-46 and the conversion was completed in 1951), the old familiar names were kept when possible and when there would be no conflict in dialing (certain old exchange names collided numerically with other exchange names, ie. [Union Stock] Yards and Warren [Boulevard] -- we kept YARds (now 927) and Warren became Haymarket [riots, meeting place of strikers] (now 421). To standardize all numbers at seven digits (for many years 'Central 1' was a private line in the mayor's office), the first three letters of the exchange name were used and the existing four digits. If less than four digits, then zeros were prepended. In the above example, Central 1 became CENtral-0001 following conversion to automatic dialing. WGN Radio with its long time number Michigan 225 became MIChigan-0225, etc. (Don't try dialing 312-642-0225 now; WGN hasn't had that number for 30+ years!) After a few years, early 1950-ish it became obvious there were not enough *workable, easily speakable, spellable* combinations to go around so a conversion was made to two letters and five numbers, with the first digit merely being what had previously been the third letter. But this now allowed other digits to be used as well, so that cases like GRAceland [cemetery and surroundings set on land which belonged to Grace, the wife of an early citizen of fame] could expand to GRaceland-7 as well as the original GRaceland-2. The same rationale was used about 1960 in the decision to go ANC -- 'all number calling'; it allowed use of number combinations like 998, 559 and such which prior were unpronounceable non-words. When ANC started, existing customers were grandfathered, and new customers got all digits on the very same prefixes. For about ten years, the directory had a mix of both types, GR-2 and 472, ROgers Park-4 and 764, etc. In many/most communities across the USA where conversion to dial service occurred prior to about 1950, the original three digit exchange will map to the first three letters in the old name. After about 1960 it was dueces wild; no attempt was made to match numbers with names; any number combination unused at the time was considered with some universal exceptions: First and second digits always 2-9 (never 0 or 1) and third digit 1-9 (never a zero). A few were held aside on purpose as part of the long range planning at the time: 976, 555, etc. That's more than you wanted to know, I'm sure! :) PAT] ------------------------------ Date: Mon, 20 Jul 92 11:04:17 -0400 From: krfiny!jeffj@uunet.uu.net Subject: Re: Telephone Keypad Question Pat's explanation of the letter assignments makes a lot of sense, but recall that it used to be American Telephone and TELEGRAPH. Telegraph operators were super careful not to confuse '1' with 'I', '0' with 'O', so one could surmise that letters and numbers that look alike would have been avoided on the phone keypad since it's also a telecommunications device. If I'm not mistaken, touch tone (DTMF) pads were used internally to AT&T many years before it was available to the public. The human factors group obviously took precedent and eliminated letters that were rarely used in order to make easy to remember exchanges. It was common knowledge that only the first two letters were used (except for 'vanity' numbers), so there was apparently no confusion. I'm still pissed that AT&T discontinued the Teletype brand name. Kids today really don't know why serial ports are names 'tty'. Telegraphs are really in the far past.

Besides PCBs from the transformer oil, there could be a problem with emissions from automobiles.

Recall that for inductive fields, the magnetic field falls off as 1/r^2 whereas for radiated fields the field falls off as 1/r. At low frequencies (such as those used in power systems) the radiated power is very low. On the other hand, the electric field from high voltage lines can be substantial. The moral of the story: don't worry too much about the magnetic field unless you are *real* close to the line (and it is carrying a substantial amount of current). Worry more if the line is a very high voltage because of the E field. > I hope your next television is kerosene powered.

This technology is widely used. But not everywhere. Some systems, particularly in RSAs do not run with this feature enabled. I personally know of about six or eight systems that I myself worked in where the company wanted that disabled. Full power, no power stepping activated at all. As far as the 'gimmick', several phones have that, including OKIs I believe. At least the old OKI 410 series phones had that I think.

Not great from a security point of view, because it cuts the probability of randomly guessing a PIN given a known phone number in half.

Your friend could have given his calling card number to a friend or relative. Cell-phone billing is generated long after the conversations are over, however it takes money and resources to do something with the questionable billing info after it's collected.

I have found that one cannot expect to get anything resembling a straight answer on any matter (from your current bill on up to "proposed services") on the first call to the business office. All light and knowledge from GTE (if you can call it that) must come from Thousand Oaks. It is amusing to note that if you do happen to call GTE about a billing question, you are told that someone will call you back "within five working days".

Of course, Pac*Bell is offering those other services NOW. However, I still cannot get them. Why? I have been told that Priority Ringing, Selective Call Forwarding, and Repeat Dialing are not compatible with Commstar, Pac*Bell's mini Centrex system for small business and residence. If I remember correctly this has been the case in other areas until the local telco figured out what the hell it was doing. > He said I was the first person ever to ask him about ISDN :-( GTE also has a great deal of trouble providing simple T1 service. In fact, in order to discourage customers from requesting such service in conjuction with IECs, etc., GTE has priced T1 through the roof. I have a client who is moving out of GTE and into Pac*Bell territory. The savings on the T1 alone will more than justify the cost of the move. > Regarding SS7 links, he said GTE was working on them between their own > switches.

But given GTE's dismal lack of engineering acumen, what the company would really like is to collect the revenue WITHOUT providing the service!

The fact that the regulatory process could *not* handle cross-subsidization between regulated and unregulated lines of business was one of the motivations behind the MFJ. As to the "very low cost of Long Distance calls compared to local calls due to the removal of cross-subsidization", A. cross-subsidization of local calls has not been removed; only the name has changed (from internal Bell System bookkeeping to the "subscriber line charge" and carrier access charges"); B. inasmuch as cross-subsidization has been relaxed, it is due to the corporate separation of the IXCs from the LECs; and C. where "the regulatory process" is trying to control cross-subsidies, e.g. costs for intra-LATA LD, the success has been, at best, questionable.

MCI does use X.PC to provide a reliable link. One problem with X.PC is that it does require 8 bit transparency which means it can run into difficulties through some paths. The newer MCI (9600bps) lines support MNP5 for compression and error correction but the reliability is only modem to modem and not end to end like X.PC, though that might not be a problem because ... MEP2 is a protocol for exchanging mail messages. It is symmetric with the two ends taking turns as master and slave. The master presents an envelope and then body parts (in the X.400 sense, not the medical sense!) which can be binary or ASCII. MEP2 encodes everything in printable ASCII so that it can run over essentially any link. It uses simple checksums for error checking. There is a retransmission protocol to recover from errors but I've always felt hanging up and retrying made a lot more sense. Since MEP2 does error checking and X.PC and MNP provide reliable links (end to end or modem to modem), MEP2 rarely gets stressed. Even without the lower level error correction, many phone lines themselves are quite reliable. One downside of MEP2 is that there is no header/envelope distinction which means you can't separate the routing information from the header and thus it is difficult to write a proper gateway between MCI and other systems. The new support for binary files in the INTERACTIVE sessions as well as the encoding of attachments exchanged with the Internet does strengthen MCI as a full mail service. Note that the Internet encoding is not really a function of MCI itself, but of the gateway that translates between MEP2 and SMTP (I assume). One advantage of MCI is that it does provide an email service for end users with national (and some international) support. Now, if they'd only deal with headers ...

He is usually kept in a bell jar slightly to the left of the U.S. Consitution in Washington, D.C. The Wollington family is noted for its devotion to public service. Hubert's sister, Jane Barbe, was for many years the voice of time at WWV and WWVH (shortwave radio stations operated by the U.S. Government); his mother, Jessye Norman, sang the 1000 and 1200 Hz ticks and minute markers at the radio stations, and his aunt, Anne Jones, was the official Canadian censor until she married Henry Spencer and converted to Collyerism, a religion similar to Unitarian Universalist, but concerned more with the exact date of the Ascension. She devoted the rest of her life to correcting time header format errors in the Dead Sea Scrolls. Hubert has two sons, Ante Meridian and Postal Mail, and a daughter, Principia Mathematica. Like most men, he was briefly married to Elizabeth Taylor during the 1970's. He is currently single, cute, and available, but poorly-paid. Any facts in the above are unintentional and should be reported immediate to the Brain Tumor Marketing Council. Thank.

The {Chicago Tribune} published every word he had to say on Sunday in the Monday papers. All the upper crust of Chicago society went to Doctor Collyer's church. When he went out of business in 1903 he sold the church on North Dearborn Street to the Masons; today it is known as the Scottish Rite Cathedral. It is directly across the street from Washington Square Park (Bughouse Square) where in 1974 I addressed the annual convention of the Brain Tumor Marketing Council and convinced them that brain tumors are not a disease but merely a type of lifestyle, convincing them to remove it as a category in their list of diseases. In your discussion of the Wollington family, you neglected to mention Hubert's famous sister Nell and her husband, Void, which is another way of describing most of this issue of the Digest.

Most prior studies have acknowledged only physical causes of repetitive motion disorders, which affect an estimated 50 to 70 million American workers. Three years in preperation at the joint request of the Communications Workers of America and US West, the study identifies 22 percent of 533 participants as victims of upper body repetitive motion disorders. This, despite the fact that NIOSH found US West in compliance with 80 percent of established physical standards for VDT workplaces, the best record of any telecommunications company whose workers are represented by CWA. "This study clearly shows that how workers are treated by management is at least as important in preventing repetitive motion injuries as the equipment they are expected to use," said CWA President Morton Bahr. The NIOSH study found that psychological considerations such as job insecurity, high productivity demands, surges in workload, lack of control over work methods and lack of support by co-workers all contribute to VDT illnesses. Its report also stated that work practice variables such as wearing bifocals or contact lenses, typing skill and frequency of arising from the chair play an important role in developing ergonomic disorders. It also found that work organization factors like overtime, task variation, and frequency of breaks are significant. With voluntary participation of 93 percent of selected employees in five occupations at three different locations, the study represents "the largest, most comprehensive scientific investigation of VDT ergonomic illnesses to date," said CWA Executive Vice President M.E. Nichols, who with David LeGrande of CWA's Office of Occupational Safety and Health, coordinated the union's participation. Conducted at US West's Phoenix, Denver, and Minneapolis locations, the study found that tendon-related disorders affected 15 percent of participants and that 12 percent manifested hand or wrist problems. Others had arm, shoulder, neck, or back disorders. The incidence of ergonomic VDT illness NIOSH found is broken down by job category: * Loop provisioning center workers -- 36% * Recent change memory admin center employees -- 25% * Directory assistance operators -- 22% * Centralized mail remittance workers -- 20% * Service representatives -- 6% Concurring with numerous studies conducted with CWA over the last decade by Dr. Michael Smith of the University of Wisconsin, the agency found that workers experienced additional stress because of electronic monitoring. Those who believed that it prevented socialization, brought on extra complaints from supervisors or increased workload were also more prone to ergonomic problems. NIOSH commended US West and CWA on their use of joint labor management committees on the regional and local levels, which led to the company's high compliance with physical VDT guidelines. The agency encouraged the committees to continue to address the physical, work design, and psychosocial causes of ergonomic VDT illnesses. ------------------------------ Date: 20 Jul 92 17:13:12 EDT From: Alan Boritz <72446.461@CompuServe.COM> Subject: Caller*ID Device: Name Delivery System > [Moderator's Note:...People keep talking about Caller-ID as a way to > screen or avoid answering unwanted calls, and they base their > complaints about Caller-ID on the shortcomings they find in their > perception of the purpose of number delivery.

Organization: National Public Telecommunication Network Date: Mon, 20 Jul 1992 17:04:11 GMT Just in case your local Bell telephone repair guy isn't as much fun as one I just worked with, I thought you might enjoy this little episode. A company I'm associated (loosely) with has an office in an office building. Most of the building is owned by one company, which has a large PBX for the building in the telephone closet. The punchdown block is above the PBX. When this little company had a dedicated phone line brought in by Ohio Bell, the installer came in with a six foot ladder. Unfortunately, that ladder was a little too big, thus putting him too far away from the punchdown block. So, instead of going back to the truck for a shorter ladder, he figured he could manage ok if he could just find somewhere to put his foot while he worked. "Hmmm, top of the PBX looks just about right -- I'll put my foot there ..." Of course, as soon as his whole weight shifted to the PBX it ripped free of the wall and smashed to the concrete floor below ... At this point Ohio Bell is into the company who owns the PBX for $23,000 for repairs to the PBX. It may go higher. Ohio Bell, being a fair minded company, wanted to just take it off the companies monthly phone bill :-) For some reason the owner of the pbx didn't agree to that arrangement :-O I'd really love to have been a fly on the wall back at Ohio Bell when the repair person came in to explain how that darn PBX just jumped off the wall :-) :-) :-) Lou Anschuetz, lou@nptn.org lou@yfn.ysu.edu lou@ysu.edu and ten's of other places.... ------------------------------ From: smw@sage.cgd.ucar.edu (Steve Welch) Subject: House Wiring Organization: National Center for Atmospheric Research Date: Mon, 20 Jul 1992 17:51:14 GMT > STOP. 10BASE-T is not suitable for residential use, because it emits > a boatload of EMI.

I had U.S West put in six pair all over the house (cost about $1K), intending to use extra pairs for some random twisted pair network, but I chickened out, mostly because I was worried about phone inteference. So I put in a short (~30m) bit of thick Ethernet, and a bunch (eight planned) of transceiver cables. I have no EMI problems (my wife is a shortwave listener, so this is a pretty good test), except I get a small amount of RFI injected into my CATV coax at 50-70Mhz from some high-frequency electronic ballasts (!?). It figures that with a zillion computers in the house, I'd have problems from fluorescent lights... I also pulled some RG-61 coax, just in case, since I had a roll of it from an earlier project. When the phone guy did the wiring, I told him what I wanted to do, and he warned me I might not be happy. He said some people do Appletalk with no problems, but he had heard of inteference from 10 Mbit networks when using spare phone company copper. I had him go ahead and pull the six pair, figuring I could run RS-232 or some such over it in a pinch. One thing I did, which was smarter than I thought, was to buy a few hundred feet of spare wire off of him. It's come in very handy when I found out I had placed a few of the jacks in the wrong place, and when I finished an office in the basement for the wife. Oh, I ended up using four pair, anyway ... > I figure you can't have too much copper in a house. Amen to that.

According to FCC rules IXCs *must* share transactional data with other IXCs. And at least one user of an 800 number is upset that a certain IXC is selling lists of people who call this 800 number to competitors. Thus, PAT mistakenly misrepresents that calling CounseLink can be confidential when he states: (I presume he is just repeating the marketing blurb he saw). > The service, known as CounseLink, is intended for people too shy or > busy to go to an office, lie down and talk about themselves. To assure > confidentiality, fees will appear on your telephone bill under the > name Telelink Companies, Inc. of Des Plaines, IL. The fact that any individual calls CounseLink is not confidential in any way, shape or form. Some degree of doubt might be cast if Telelink has many different services all using the same number. Also, in regards to the comments about 1-800-ATF-GUNS and ANI, and then PATs comment that other organizations "all use 800 numbers also, with ANI, I'm sure." (BTW, I know of at least one organization that does not get ANI.) It is irrelevant whether or not the organization gets ANI, because the telco can sell the information to whomever it wants. Thus, even if organization goes to great length to make sure they don't know the number a person is calling from, other organizations can purchase this information. (I don't know how widespread the practice is, but it is not illegal). If you need confidentiality, do not call from home, do not use a telephone credit card, etc. David [Moderator's Note: I think telcos only have to share information on calls where *billing information* is required ... not for any other purpose.

Reply-To: Irving_Wolfe@happy-man.com Organization: Happy Man Corp., Vashon Island, WA 98070-7399 Date: Mon, 20 Jul 1992 17:11:15 GMT We've had a Panasonic 12/32 phone system here for about three years and it is starting to fail. Incoming DISA callers have not been able to get back out on another line for some time, but we could live with that. Now, unfortunately, we're having intermittent problems with general incoming calls through DISA. Most of the time, it still works. But sometimes, callers don't get the outgoing voice message. Other times, the system won't respond to their attempts to tone-dial an extension. Still other times, it won't automatically transfer to operator if they fail to dial an extension. We're running six lines and about 26 extensions, over half of which are standard two-wire phones or devices. The only other thing I know of that's wrong with the system is that one or two of the extension jacks don't work properly, but that was no problem since we still have more than we are using. What's the best thing to do? Shall I invest in another DISA card for over $500? Is the system really badly designed, so I should avoid throwing good money after bad and replace it with something more robust (and if so, what)? Thanks!

Of course, someone can manufacture counterfeit cards, but it's more difficult to do than peer over someone's shoulder. Also, since it is a stored value card, other carriers would have no incentive to honor the card (they won't get paid), so they could try to vandalize the card or more likely just reject it. Thus, protection from AOS overcharging. Of course, certain federal agencies won't like number three, so Congress will have to pass a law requiring that (1) each phone record its number and time of use on the card; and (2) that each buyer send in his/her used cards with proper identification. Failure to do so would result in a $10,000 fine per card.

The island, off the coast of Florida, is accessable only by boat or small plane, and while we have electricity, there is no phone service on the island, except for cellular. The nearest big city is Tallahassee and the cell provider of choice on the island is Centel Cellular. Their nearest tower is about 30 miles or so from my house on the island. I borrowed a phone from Centel for a few days and found that by mounting a mag-mount antenna on a scrap of roof tin and placing it on the roof, I was able to more-or-less reliably work the cell tower. The "meter" on the Motorola bag phone showed two bars. I have two questions. First, when I received calls on the phone, occasionally, after a second or two of conversation, the call would drop and be replaced with a ringing tone or a busy signal. Since I was in a "fringe area" and about the same distance from another B cell system, is it possible that I was getting some sort of intermod? Secondly, while the signal was fine most of the time, a few times it was too scratchy to really have a conversation and I was unable to use touch-tone devices like my answering machine at my other house. Would it be possible to build or buy a directional antenna aimed at the nearest Centel tower? Does anyone know of a source for plans? I was thinking that a little yagi might be the ticket.

Organization: Youngstown State University Date: Mon, 20 Jul 1992 13:55:14 GMT First, I expect the answer is 'nothing', but I'll toss the question out anyway. My home computer has a V.32 modem, to connect to another one at the university. I rarely call anything else, other than one or two 2400 baud BBSs. In addition the computer has a nearly-unused fax-modem (2400-baud+fax). I'm running MSDOS, not Unix. Most of the time I use the modem for terminal emulation, although I have both SLIP and UUCP hookups defined for it that I use occasionally. Will ISDN do anything for me in this environment ?

The problem with my PD (Suffolk County, NY) is that if I wanted to make a non-emergency call but yet talk to a policeman/woman, I would be told to call 911 in about 90% of the instances. An example happened to me last year. I was rummaging through a closet and came across an old Army style ammo box with live ammunition in it left over from the days when I went hunting. I called the precinct, was told to call 911 who told me to call the Emergency Services unit, who told me to call the precinct. I ended up going to the precinct and dropping the stuff off there.

I have always understood 911 was to be used ONLY in cases of dire emergency when police or fire fighter intervention was needed immediatly. Don't report stolen cars or burglarized homes to 911; the danger is long past. Use 911 when a police officer is requested right now to stop a crime in progress ... period. All other calls should go to the district station. And that is the way the CPD officially tells us to do it. But you call the district station to report something which is going on (not an emergency) or something which happened, and you get told to 'call 911 to report it'. Once every few months or so 911 officials complain about how overloaded the system is, and why they are sometimes unable to answer for six rings ... I wish our police department would settle this once and for all, and make an official policy that everyone had to stick to.

Australian phones with letters as well as numbers have the 'Q' and 'Z' on the '1' key. Australia hasn't been a user of words in telephone numbers, but all that will change under deregulation. In rsponse, all new phones sold by Telecom Australia (the former monopoly carrier) have keys labelled with letters as well as numbers. Cheaper phones made by other manufactures have had letters for a long time, probably because they used the same phones made for the US market). On the new Telecom phones, the '2'-'9' keys are labelled with the same letters as US phones. However, the '1' key is labelled with 'Q' and 'Z'. Also, automatic teller machines (at least over here) which have keys labelled with letters as well as numbers (for easier to remember PIN's), also use the '1' key for 'Q' and 'Z'. I believe this applies in the USA as well. If this is the case, the most obvious place to put the 'Q' and 'Z' would be on the '1' button.

In June, he demonstrated this program in CAPITAL's office in Duesseldorf, in the presence of some experts from a criminal agency and an IT security experts. German Telecom was informed days ahead the presentation but could not trace his dialling experiments which lead him from Duesseldorf to Canada (known as normal entry of European Phreaks to the New World), and so on. Kimble said that non-traceability be a major new feature of this blue-boy program "Unlimited Assess (Multi-Frequency Dialler)". Phreaking was practiced, for some time, also in Hamburg's Chaos Club. In last year's Chaos Congress, they once more held a seminar on Phreaking (given by the Dutch Hac-Tic group; the German report on this part is available, with the Chaos Congress' documentation, either from CCC or from Virus Test Center's ftp site). CCC and Hac-Tic freely distributed information on blue box programs for PCs and 68000 systems. Due to this action, the price of a blue box program went down significantly (from about 500 DM to about 100 DM), and one can upload blue box programs together with games from ordinary BBS. But German Telecom said that the holes which these programs exploit have been patched. When CAPITAL first contacted me (before the experiment), I was not very impressed. But the the experiment continued, and some really shocking results were reported: when German Telecom could also neither trace nor intercept a second experiment, they reportedly asked some Canadian experts for assistance. When they watched and tried to close the hole, they observed that somebody just worked in their "system" to implant some Trojan horse (don't ask me how, because if I believe Telecom, there is ***no connection to the outside*** When they patched the holes in changing some frequencies, this evidently was immediately "mediated" (path unknown) to the phreaks (organised in a group "Dope", evidently working internationally). Unlimited Access comes with a 1-year guarantee of free updates of frequencies: this is different from other blue-boy programs and may verify the unusual price (15,000 DM, about 10,000 $), but remember that this program excludes being traced by Telecoms! And the group evidently "received" the updated frequencies immediately and distributed them to their "clients". Just for *caution and clarification*: due to the stress of end-of-semester, I couldnot personally observe the experiment. My report is based on some telephone discussions (not bluebox-dialled) with the journalist, on the assessment of a participating colleague which I trust, as well as on some discussions which I had with Telecom on related matters, and with some phreaks in my neighbourhood *:) Klaus Brunnstein ------------------------------ From: uum1!kksys!brainiac!jrc@uunet.UU.NET (Jeffrey Comstock) Subject: Minnesota Caller ID Testing? Organization: Sewer of Source Code Date: Wed, 22 Jul 92 08:34:48 GMT About three months ago, I was mucking with the phone and depressed *60 on my telephone. Then I hear a voice that says "Your selective caller rejection service is now ON. Please enter a command or wait for the menu ..." *62 gave the message "Your selective call distinctive alert is now ON ..." *63 was "Your selective call forwarding is now ON ...". I guess that US WEST was testing CLID here. I wanted to get some hardware to see if Caller ID would work, but never got around to it. It would have worked right ? Oooh boy did I have fun with that. In my calling area there are about 300 exchanges, and it was only flipped on in about 20. I am in the 854 exchange, and I could reject and distinctive ring from 830, 831, 931 and some others, but it didnt work in any exchanges that I had freinds or family in. If I tried my brother for instance, the 'canned lady' would say "We're sorry, this service is not available with that number." I could selectively forward a call from an activated exchange to ANY number. I am in an apartment with a security phone in the lobby -- you have to call me from it to get 'buzzed into' the building. I programmed my phone to give me a distinctive ring if someone called from the lobby, and it worked great. (PS: My apartment managers answering machine went berserk from the distinctive ring when I programmed his to do it. It was set off to answer on the fourth ring, and the system would do three short rings and one long one if someone called from the front door. I have an AT&T 1337 digital answering machine, and it was immune from this problem.) Well, a few day's ago they flipped it off. I no longer have control over it. *60, *61, and *62 just give me a fast busy. But guess what -- I still get distinctive ringing from the front lobby! Yeah -- I realize somebody from US WEST might read this and correct this 'problem' for me -- no biggie. Also, I remember that I had 854-1234 programmed for selective call rejection. Maybe I will get lucky and that is the IRS's or some other number I don't want to bother with. (yuk yuk). I also heard that a guy in the 931 exchange (it was active there) was phreaking it, and depressed *73 or something and got a message like "The last number that called you has been traced and a $10 charge has been added to your bill." He called the operator to make sure that he wouldnt get billed for it, and they insisted that no such service was available in Minnesota. He did'nt get the $10 charge,and mysteriously the *73 trick ceased to work. Jeffrey R.

Here's the situation: I recently moved to a new area, and got call waiting service on my home phone. To call into the computers I use as a student at U-M, I can dial into either a 2400 baud number or a 1200 baud number. When I'm able to get through to the 2400, there are no problems at all (it's often busy). When I dial into the 1200 baud line, and leave the call waiting feature on, the modem connects and then all I get is garbage. When I turn off call waiting(*70), the connection is fine. This has happened daily for about 2-3 weeks, at various times throughout the day. I've contacted the network I'm calling, who say there is nothing wrong with the number I'm having problems with. I've called Michigan Bell, who tells me that they've checked the line and found nothing wrong. My belief is that *something* occurs when I turn off call waiting, but I don't know what. (Note: the obvious answer, "just turn it off", isn't acceptable. One of the reasons I have call waiting is so that people can reach me when I use the computer for hours.) Does anyone have experience with this, or any suggestions? I do not read news often, and rarely follow this group. Please e-mail suggestions to lik@caen.engin.umich.edu or just lik@umich.edu or call me at (313) 522-5969. Thanks for the help.

I agree that there must be a better way to signal the subscriber that there's a voice message waiting than to play games with the dial tone. Now that Caller-ID can deliver text as well as digits, why not have the voice mail ring you and send the caller-id box a message such as "voice mail" with your phone number in the number field. Two rings is all it takes. If you pick up the phone (or don't have Caller-ID), a recording will tell you "you have voice mail, enter your id to start" (and time out should your answering machine get the call). Or perhaps yet another unique ringing pattern for voice mail to get your attention. Give two quick rings every hour (but silent from 10PM-8AM if you choose that option)? Doesn't that new feature "annoy-a-call" do that (repeatedly attempt to contact the destination with your pre-recorded message)? There's a tradeoff between giving the service to people with their existing equipment (no Caller-ID, no message lights) and people willing to purchase new equipment to use the enhanced services conveniently. The studdering dial tone meets some of those goals.

On close inspection of this rather curious and wonderful gadget, I realised there is a lot more to it than meets the eye. However, I simply cannot figure out what it is. This thing is manufactured by LANIER BUSINESS PRODUCTS, INC (Atlanta, Georgia, USA), and it has a MODEL P-101 printed underneath it. It resembles a telephone answering machine/dictating machine/modem. It has a speaker but no mic. There is a small tape recorder with the associated buttons plus a 'telephone' push button on the console. The other switches and buttons on this machine which are located around and underneath it are: DIC-CONF; OFF-SCAN; MIC-SPK; RECALL-1.2.3; A headset jack socket; a record gain knob; telephone jack socket; a TOTAL and a RESET button; three knobs that control SPEED (presumably that of the recorder), TONE and VOLUME; and finally a SCART like socket. Incidentally, there are some seven-segment led displays on the console to show 'unit no.', 'complete units', 'instruction' and 'location' for DICTATE option and 'unit no.', 'total units', 'remaninig length' and 'instruction' for the TRANSCRIBE option. If any of you have ever come across a gadget like the above please let me know what it is (and how it operates, if possible!).

AT&T claims that Canadian companies fail a "test of equivalency" that was required by the FCC in conjunction with opening up international communications. Fonorola replies that American resellers are already allowed, and is thus sifficient for the equivalency required by the FCC. Under free trade terms between the U.S. and Canada, there are concerns this dispute could put requirements for local service subsidies from long distance at risk. That is, a "level playing field" imposed on Canada could mean skyrocketing local rates for Canadians, a situation regulators sought to avoid when permitting long distance competition in Canada. dleibold@vm1.yorku.ca ------------------------------ Date: Wed, 22 Jul 92 12:04:00 PDT From: lauren@vortex.COM (Lauren Weinstein) Subject: List of GTE Southern California SS7 Links john@zygot.ati.com (John Higdon) wrote: >> Regarding SS7 links, he said GTE was working on them between their own >> switches.

John, as I've told you before, it isn't baloney; GTE has numerous SS7 links up and running, at least in Southern California (I don't have info, one way or another, about Northern California). Some of the offices with SS7 interconnects include (and these are all carrying regular traffic, not test links): Granada, Pacoima, San Fernando, Sylmar, Sunland, Sepulveda, Camarillo, Oxnard, Thousand Oaks, Quartz Hills, Lancaster, Santa Barbara. More SS7 sites are coming up on a regular basis. The Santa Monica STP (Santa Monica, Mar Vista, West Los Angeles, Malibu, Topanga, etc.) is slated for SS7 this September. Neither Pacific nor GTE has shown much enthusiasm toward fast action on GTE<->PacBell SS7 links. Both seem to be more concerned with their own offices and with connections to the long distance carriers at this point. --Lauren-- ------------------------------ Date: Wed, 22 Jul 92 16:14:04 NZS From: David Norman Subject: Coda Call (was Teleslime etc.) Our local press here in Wellington carried a short article "Sick of junk calls" describing a device called "Coda Call". This requires a three digit PIN to be appended to all incoming calls before "connecting". A Joseph Lutz is credited with developing the device. Does anyone have any further details? It would seem to be an excellent answer for eliminating telemarketer calls for example. I'd be particularly interested in what happens to callers who have dialed the published directory number; do they just get ring tone no reply? Please feel free to e-mail me directly; I'll happily summarize responses. Dave Norman e.mail:norman@corp.telecom.co.nz Telecom Corporation of New Zealand [Moderator's Note: If it works like the PrivCode device here in the USA, it sits on the line all the time looking for changes in voltage to indicate a call has been connected. It then seizes the line before the phone has a chance to ring (subscriber is not disturbed with the bell), and the PrivCode synthesized voice says 'enter your PrivCode please'. The three digit number which follows is then dealt with. After two or three wrong attempts, the device just drops the call. If the code is one of several authorized, then the device itself warbles to get the attention of the subscriber. Warbles come in different cadences to partially indicate who is calling, based on the three digit code entered. Certain codes are reserved with one always ringing the answering machine plugged in, another just giving a ring back tone to the caller (but silence to the subscriber) and eventually telling the calling party politely 'no one is answering -- goodbye', and other codes which will first attempt to signal the subscriber then default to the answering machine after several rings. PrivCode was first available here in the early 1980's, and the patent is held by International Mobile Machines of Bala Cynwyd, PA ... so I doubt the newspaper was correct about the person who 'invented' it.

The way I read the Compuserve message in their GO FCC forum, and the referenced discussion in GO TELECOM (not to be confused with the TELECOM Digest), CIS is concerned about two separate issues. First, although they fail to give the docket number, they appear to be concerned with Docket 89-79, which had a "Final Rule" promulgated about a year ago. CIS appears to want their users to support the Petition to Reconsider which has been filed by the industry group ADAPSO, among others. Second, CIS attributes to an unnamed FCC commissioner the thought that some kind of a modem fee might be reasonable. They also want to attack that principle. The troublesome thing about the CIS messages is that they have an enormous lack of detail. So much so, that I'm afraid most responses generated will go immediately into the bit-bucket@black.hole.com.

If they want to upgrade their type of connection into the LEC network, then they must pay the higher rate. Whether this is fair or not, it's not really news. It seems that CompuServe wants to use the newer services, but not pay the higher rates that would result, and is stirring up the "modem tax" issue to put public pressure to change this.

This is, like the flu, yet another strain of the virus. Offhand I think it is somebody's reaction to the FCC's ONA (Open Network Architecture) rules, which have applied a _federal_ tariff for ONA services, but with each telco making up its own rules and rates for the FCC to approve. The ONA rates are set at levels close to what carriers pay (and that's what the "modem tax" was; making Enhanced Service Providers pay carrier rates rather than user rates). So CI$ et al won't be able to use ONA. But the FCC has said that making ONA _available_ (even at ridiculous rates) is a prerequisite for the carriers' offering their own competitive (controvesial!) services. So the FCC has taken this fig-leaf of unreasonable ONA offerings and allowed it to enable the carriers to do something _other_ than be carriers. That's enough for CI$ and any other right-thinking American to get upset. But it's not a modem tax. It has nothing to do with modems. And it has nothing to do with taxes. It's a tariff dispute, and it's likely to be settled in Congress. (BTW, in the latest "WeldBulgermander" map of Mass.

John, You seem to be implying that there are people in "...the land of the free and the home of the brave..." that would like to do away with our First Amendment right to freedom of speech. What can members of the bbsing community do to prevent intrusions on our most basic rights? Do you think continued attempts to trample our most basic freedoms will eventually make America a socialistic state? On a different note, however, I might add that there ARE departments of the government that make vital database services available to telecommunicaters (bbsers?) at MUCH lower rates than commercial enterprises offer the same information. I have subscribed to Medline for five years or so, and there is no commercial enterprise that makes this source of medical citations available at such an affordable price. I might also add that until several years ago, some of the government-operated bbses in the DC area were among the best BBSes in the country. Least we forget, the government also runs (or supports to a large extent) the Internet. I don't think we should knock the government excessively. I think if the government could cheaply make a service like Dialog affordable to the masses they would be doing a major service. I guess I have mixed feelings about government involvement in telecommunications because on one hand I would like to see more government involvement, but I say this only if it is going to make more information available to me at less cost, not less information at more cost. Last, which presidential choice do you think will do the most to help not hinder BBSING/online data retrieval in the US in the mid-1990's in America? I really would like to know as this will be a definite deciding factor in my vote for president this November. pdh@netcom.com (Phil Howard) responds to TELECOM Moderator: >> [Moderator's Note: Well, here we go again.

The synopsis: if you haven't been nailed by phreakers, you will be. Phraud in the United States accounts for $4 billion a year in toll charges. The article discusses "shoulder-surfers", the slimebags with video cameras, binoculars, or keen vision lurking in airports and other likely spots, who record your phone card number as you dial it, "call-sellers", the people who take these numbers and stand on streetcorners in areas with large immigrant populations selling phone calls home for $10-$30, and the linkage between phreakers, "shoulder-surfers", and drug dealers. Also, it talks about the inherent dangers of DISA well-known to readers of TELECOM Digest, as well as what some telecom firms are doing to combat phraud.

Pleasant Avenue Livingston, NJ 07039 Dear Mr. Suchyta: We are sorry that the information published in the Winter 1991-92 issue of 2600 disturbs you. Since you do not specify which article you take exception to, we must assume that you're referring to our revelation of built-in privacy holes in the telephone infrastructure which appeared on Page 42. In that piece, we quoted from an internal Bellcore memo as well as Bell Operating Company documents. This is not the first time we have done this. It will not be the last. We recognize that it must be troubling to you when a journal like ours publishes potentially embarrassing information of the sort described above. But as journalists, we have a certain obligation that cannot be cast aside every time a large and powerful entity gets annoyed. That obligation compels us to report the facts as we know them to our readers, who have a keen interest in this subject matter. If, as is often the case, documents, memoranda, and/or bits of information in other forms are leaked to us, we have every right to report on the contents therein. If you find fault with this logic, your argument lies not with us, but with the general concept of a free press. And, as a lawyer specializing in intellectual property law, you know that you cannot in good faith claim that merely stamping "proprietary" or "secret" on a document establishes that document as a trade secret or as proprietary information. In the absence of a specific explanation to the contrary, we must assume that information about the publicly supported telephone system and infrastructure is of public importance, and that Bellcore will have difficulty establishing in court that any information in our magazine can benefit Bellcore's competitors, if indeed Bellcore has any competitors. If in fact you choose to challenge our First Amendment rights to disseminate important information about the telephone infrastructure, we will be compelled to respond by seeking all legal remedies against you, which may include sanctions provided for in Federal and state statutes and rules of civil procedure. We will also be compelled to publicize your use of lawsuits and the threat of legal action to harass and intimidate.

The court ruled that the appeal could proceed, possibly in the fall. Bell wants to change some of the terms of the decision to allow long distance competitors access to Bell's network, particularly the 70% share of the initial interconnection costs that are to be borne by Bell, with only 30% borne by competitors. Unitel claims that a delay of six months getting to the marketplace would cost them about CAD$588 million. Bell Canada and other existing Canadian telcos consider the CRTC decision to be "expropriation" of Bell's assets without adequate compensation. The decision requires Bell to allow for test facilities to be set up for competitors, though the actual interconnection has to wait until the appeal is finished. The legal wrangling is no doubt part of the competitive process, as are advertisements shot by one party and another. Unitel recently placed an ad featuring two babies, one dialing a toy telephone with the other bawling away at the idea of the other having the phone. Unitel's ad quipped that it was not easy being the only child (referring to Bell, et al) for so long, and touting the benefits of competition. dleibold@vm1.yorku.ca ------------------------------ From: quonw@software.mitel.com (Wynn Quon) Subject: Recommendations Wanted For SS7 Test Equipment Date: Thu, 23 Jul 1992 15:31:18 -0400 Organization: Mitel.

Organization: The World in Boston Date: Fri, 24 Jul 1992 02:01:40 GMT Hi, About all the discussion of 'phone companies being allowed into video delivery, and already being allowed into information providing, and demonstrably using their clout to squelch competition, and so on ... At the IETF last week I said to several people, to much amusement: Voice is An Application Layer Protocol which was especially poignant in light of the successful IETF audiocast on the Internet. I will make a prediction on the record: Voice (and Video) on Internet packet technology is going to utterly destroy the competitiveness of *all* of TPC's current technology in the next 5 years. Unless they get their packet switching act together, they will find that all they are doing is leasing circuits to people running TCP/IP (v4 or v7 :-) with all the interesting stuff being run on top. ISDN packet mode might be useful if they actually provide it, ISDN circuit mode will be useful in some cases. (In both modes, the use is to carry internet packets.) But if they don't get it right, including pricing it at something comparable to real cost, they will be bypassed by *everyone*. All I need is bandwidth to my local Internet service provider; once I get there, it is all packets. I don't have to pay $2.58 for Call Waiting, $2.57 for Forwarding, $4.12 for 30-Number Speed Calling (all real NYNEX rates, from Boston directory, Sept 91). I can have any feature I can program into my PC, or get it for the cost of a shareware program. (call waiting; 42-way calling; calling-address-or- whatever-I-damn-please-dependent forwarding; as many speed codes as I care to remember ... :-) During the IETF audiocast (which was apparently 'on' 24 hours a day, but only used for presentations during daytime in Boston's time zone), one observer noted a couple of people, both in Australia, using the "Internet Citizen's Band" to discuss some unrelated issue. When asked why they were using it: "It's cheaper than a 'phone call." And so it is. And there was a videocast too. I pay NYNEX about $24.00 a month for a copper loop that can do 14.4 full duplex if I push it. Boston Cablevision delivers 106 channels for $60.00 month (counting, but not paying for, some PPV). That is what? Maybe 20GB? More? Who do you think I am going to buy packets from? With eight orders of magnitude difference? (NYNEX is about US$1.5/KByte/sec/month, the cable company about US$0.0000003/Kbyte/sec/month) Yes, I understand the difference between the value-added of the switching; but the cable company could (for example) provide a complete usenet feed with a vanishingly small fraction of its bandwidth; most processed information flow (measured in receiver*time) is _inward_, i.e. from 1 person to N people for _very_ large values of N. In short: Once the available bandwidth is converted to unregulated packets (Democratic Packets :-), all regulated service providers will either compete or get blown away. And this is happening NOW, and will reach critical mass very quickly. Seen a vinyl record lately? Tried to buy one? Um, and did you *have* a CD player ten years ago? You probably have a PC now ... Once the technology to go digital/packet is available, it is inevitable, and imperative, and immediate.

The Division of Ratepayer Advocates determined that Pac*Bell has been using regulated revenues to support competitive services since January of 1990. A service is considered competitive if it can be supplied by other vendors. The CPUC says that Pac*Bell services such as Voicemail, PC Connection, California Call Management, and Smart Desktop were all subsidized by regulated ratepayers when they should have been financed by shareholders. Need I say more? Yes. Those who naively believe that regulation of cross-subsidization is a trivial matter should consider this: yes, the PUC caught Pac*Bell with hands in the cookie jar. But how many VM providers, IPs, and other independent businesses did Pac*Bell drive out of business before this discovery? (I know of several ...) Please, can we finally see that RBOCs have NO BUSINESS getting into competitive business. And particularly, they have no business getting into competitive business that depends upon use of the LEC network. There is not enough PUC horsepower in the world to supervise this madness. The RBOCs are masters of this game and will ALWAYS win. All of this push to allow them into information and other competitive services is terribly wrong thinking. RBOCs do NOT have the public's best interests at heart; they hold their stockholders' interests paramount. And that is the way it should be. So let us at least not just bend over. John Higdon | P. O.

In Wilmington, Delaware, the directory released in October 1966 was the first there NOT to have the exchange names, although since about 1960(?) some exchanges had been created which never had names (737 in Newark, Del., for example). POrter 2 & 4 (now 762 and 764) in Wilmington had been created in 1957 (had to read this because I am too young to remember it). But the 1976 Philadelphia directory was still using exchange names. As in the Wilmington case, these were the two letter + five number type; the cases (cited in the Digest) of three letters and four numbers are too far back for me to remember.

This subject has been under discussion in both ISO and CCITT. Agreement has been reached on where 24 of the 26 letters will go, but the Q and Z location is not yet agreed. The holdout is AUSTRALIA. Several human factors studies have shown that users expect the Q to follow the P, and the Z to follow the Y. There are thousands of voice mail systems and directory access systems that use this convention. While I was in Australia I want into a shop that sold telephone sets, and saw sveral sets that had letters on the keypad. None had Q and Z on the "1".

What were the xx0 exchanges being kept for? [Moderator's Note: From the beginning until the early 1920's when dialing began there was no real concern in the matter. The operators understood the different words; that was all that mattered. To their credit, Chicago Telephone Company made a point of skipping names which would be 'numerically ambiguous' beginning sometime in the 1920's in anticipation of it making a difference several years later. But those which were in use stayed that way until the first of the two (I do not know of any instance where there were three) converted to dial. It then got a new name which would not be ambiguous to the equipment. In the beginning, people who wanted to know the weather outside lifted the receiver and asked the operator what the temperature and conditions were. Eventually this became a specialized task, but the subscribers still asked the operator for WEATHER and were plugged in to the place where it was recited continuously. Among the first conversions to dial in 1939 was W-E-A-T-H-E-R, but that was short-lived for some reason with a change to WEather-4-(anything, with 1212 the official number) and a new CO called WEbster-9 showing up downtown. WEather-4 went away in favor of 934, then 936, and finally (free) 976 followed by (pay) 976. Webster could have become WEBster but for some reason it became WEbster-9 instead. I can't divine their thinking from that long ago. Instead of happening overnight as in a small town, the conversion from manual to dial service went on for years here, and led to lots of confusion by subscribers. Dial customers dialed each other; manual customers asked the operator for connections to each other or the dial customers; dial customers calling manual exchanges sometimes could dial them (!) but other times had to dial 911 and wait for an operator to answer and pass the request. When I was a child I stayed up late the night our CO converted to dial, making a manual call at about 1:59 AM, and a dial call a minute or two later. My friend's phone did not convert for another year; I dialed 911, waited for an operator to answer and gave his number; to call me he just gave the operator my number. 911 (?) ... I see your eyebrows raise ... the police were called via POLice-1313; a fire was reported at FIRe-1313. Emergency use of 911 started in the late 1970's here. During the manual to dial conversion 511, 711, and 911 were dialed to reach operators in unconverted manual exchanges around the city. The '0' operator was not to be contacted for those calls. 511, 711 and 911 just 'dropped into' the manual offices and showed up on the operators switchboards. Each time you gave your number to anyone they'd always ask "Are you getting converted soon? Get to keep the same number? ..." PAT] ------------------------------ From: brendan@otc.otca.oz.au Subject: Re: Telephone Keypad Question Date: Wed, 22 Jul 92 18:06:51 +1000 I have seen many variations on the letter groupings on telephone keypads. The most common appears to be: 0 - 5 JKL 1 - 6 MNO 2 ABC 7 PRS 3 DEF 8 TUV 4 GHI 9 WXY The missing letters (Q and Z) are sometimes put on the 0 or (more commonly) the 1 key. However, I have also seen one labelled thus: 0 - 5 MNO 1 ABC 6 PQR 2 DEF 7 STU 3 GHI 8 VWX 4 JKL 9 YZ And even one labelled thus: 0 O 5 KLM 1 I 6 NPQ 2 ABC 7 RST 3 DEF 8 UVW 4 GHJ 9 XYZ All of this highlights one thing - absolutely no keypad lettering standardization. In fact, the future use of vanity numbers is something that concerns the CCITT, as vanity number use may become more prevalent rather than less and will transcend national boundaries. I believe that the CCITT is currently looking at this issue (perhaps someone in the know can confirm or deny) with a view to creating a recommendation on keypad letter groupings and hence for the first time an international standard. Also, the CCITT won't necessarily adopt what is most common, but would adopt what would appear to be most sensible and useful. We may even get a type of QWERTY layout to evenly spread out the commonly used letters :-) Of all the letter permutations I have seen, the last one (IMHO) is the best. It eliminates any possible confusion between 0 and O, and 1 and I, and the rest of the letters neatly fit. Its shortcomings include the effective wiping out of vanity words beginning with O or I, and the letter frequency spread is not that good (9 would get used little, but 7 would get used often). Can anyone suggest a loyout that has a roughly even letter-frequency spread and minimises potential 0/O, 1/I, 2/Z confusion?

One of the more significant developing technologies is real time data compression for, among other things, telco digital transmission systems.

Where I used to be, they wanted you to call 911 for nearly everything for two reasons: 1. Some people's idea of what constitutes an emergency is more than others. Better the trained dispatches at 911 identify the call than to lose valuable time while someone worked through the switchboard at the local precinct house or had the phone ring off the hook at the volunteer fire statoin. 2. All there fancy ANI/ALI/"who do we relay this call to" stuff only works if you dial into 911. If you call in on the regular phone, they have to get your address and go ahead and type it into the computer anyway so they know who to send out (even in a non-emergency). Of course, each juristiction runs it's own 911 and some are more coordinated than others. I still feeel a little odd calling 911 to report stuff in the road and look up the non-emergecy number (in the Gumn't pages of the phone book, it isn't on the inside cover like the emergency numbers).

There are cards available now for PC's that support ISDN, such that you could have the campus network extended to your home. You would need a line, a line on campus, and two such cards. There are also stand alone terminal adapters that look very much like high speed modems in the conventional dial-in paradigm. Additionally, there are boxes available that take ISDN basic rate in one side and give you ethernet out the other. You can get up to 128Kbps from a PC card (using both B channels on a Basic Rate Interface). Terminal adapters generally go to 38.4Kbps through a serial interface.

The most common problem I have with AT&T cordless phones (love my 5500) is that the contacts on the phone and charger get dirty. If the model you have has a "Charging" light, check to see if it stays on when the phone is in the base. If not, get steel wool (can use other scrubbers, but steel wool works best) and clean off all of the contacts.

The last thing you want to do to a NiCad battery is to run it completly dry. You run the risk of destroying one of the cells which sounds like you may have done. All is not lost however, there are commercial battery houses that sell replacement batteries and they aren't that hard to replace.

[Moderator's Note: All the special three digit N11 codes used for connection of dial subscribers to the (still) manual exchanges went away once the conversion was finished. After 1951 I don't think we had any until about 1955 when a couple places in northern Indiana which were in the Chicago local calling area were converted to dial; then people on the far south side of Chicago who had been dial for a few years were told to use 911 to reach the manual exchange in Whiting, Indiana for a few months. (Previously everyone dialed the operator to ask for a Whiting number; we kept doing that, but the southern end of the city and a couple suburbs out there suddenly were told use 911, and use 711 for East Chicago, IN (which cut to dial about a month before Whiting, and about a year after Hammond. All three of those towns are in the local calling area for Chicago-Mitchell and Chicago- Pullman.) From about 1942 - 1946 we had 811 for 'priority long distance calling'. If you were of sufficient military rank you used that as a way to get the operator to take a circuit from someone else and give it to you if needed. From 1946 to about 1980, the use of 811 was for 'hotel time and charges' type long distance calls. We got 911 (as in police) about 1975-76, a few exchanges at a time, with the unconverted continuing to dial POlice-5-1313 until their conversion was made. By 1977 everyone here had 911 except one lousy exchange which was still an old panel office. I remember the first year of the almost complete conversion: The phone book devoted a couple pages to big, garish cartoons and bold face digits '911' to advertise it, with only a tiny mention near the bottom of the page: "Subscribers on the LOngbeach-1 exchange should dial the operator and tell her about the emergency."

Well, you have another problem. Letter frequencies vary by *language*. I don't have my references handy, but from my reading in cryptology, i can tell you that the variations are quite marked. So *which* language do you optimize for? Oh yes, if you are dealing with written "numbers" you have at least one other possible confusion.

I'm sure something like I describe must exist, but we don't > know what it is called or where to get it. Please help. I don't have a virtual solution, but I do have a very flexible programmable hardware one. The reason that dialback modems are sometimes not secure is that a cracker can call into the modem and wait for the modem to hang up, and then remain on the line, playing dialtone back to the modem. The modem "thinks" it is dialing on the network, but instead it reaches the bad guy's modem. This is possible because many central offices will keep the circuit up for up to about 22 seconds if the calling party remains off-hook after the called party goes on-hook. This is a long enough window for the dialback modem to re-seize the line and start dialing. You can attach an external security device, such as the Proctor 46300F2 Secured System Access Line. It answers a ringing line, then expects a security code (up to 14 digits) before ringing into the modem. This should be enough security, unless of course someone finds out what the security code is. When performing dialback, it can call different dialback numbers linked to different security codes. To prevent the problem mentioned above, it can be programmed to wait for a CPC pulse on the line before initiating dialback, or it can perform the dialback on one of several separate ports. Since the dialback can be done on a separate line, there is no way for a cracker to get through with the dialtone trick. This product can also be used as a secure DISA adaptor (a device that allows one to dial in and seize another line for outgoing service, such as a PBX extension), and is available with an internal voice frequency repeater.

When moved into my house in NJ, the house was sporadically wired for two lines (some wall jacks had wires behind them for both pairs, some only one). Having five computer programmers living there we had already ordered ten lines (oddly enough the phone company finally caught on and stopped offering "teen" lines for $4.00 additional a month). I pulled 25-pair cable into the major rooms (my office, Liz's office, the hack room, and Rehmi's bedroom) as well to the laundry room (the other side of the exterior wall from where the NI was). Everything was cross connected on 66 blocks in the garage. I also pulled thin ethernet. We ran the ten lines everywhere and used the remaining pairs for things like RS-232 lines. One day, about half the lines stopped working. I called the phone company and they came out and decided the problem was with the internal wiring (they hadn't been inside yet, they were still at the NI). I had noticed that we were paying 30 cents a month or something for wire maintenance (not my idea, I didn't place the order when we moved), so I told him to have at it. The installer was sure suprised when I showed him where the wires went after the demarc. After about 20 minutes of puttering around with an ohmmeter he calls me over and says that he's identified which run of the 25 pair is bad. We head to Liz's office. The 66 block here is not attached to the wall but is sitting on the floor (no closet in her office, I was going to screw it to the underside of the built-in desk). We pulled it out a bit. "Can't you smell it I say?" The phone installer can't tell, but some cat has pissed into the 66 block (we had new kittens). We finally agree that he will provide me a few 66 blocks and other miscellanious parts (bridge clips) and I'll take care of repuncing that block.

Yes, when you can find them. For instance, the Little Rock phone book used to dedicate the first page to all the numbers of the police, fire, etc. departments in central Arkansas. This now has been reduced to a listing for all major services of 911 (in big print). Referring to the "helpful numbers" section in the "blue pages" gives police in most communities as 911.

In the city of Los Angeles, there are non-emergency numbers for the LAPD dispatchers which do not pass through 911. I use them to call regarding loud parties, gangbanger conventions, etc. They usually result in a wait -- often zero-time, but more typically a minute or two, occasionally 20 minutes. They DO dispatch for this stuff, believe it or not. One night I was awakened at 2 AM to the sound of rap. I went to the window to see where it was coming from, and it was from the rear of a medical building about 800 feet from my house and maybe 15 stories down the hill. With binoculars, I looked to see what was going on and saw that a couple of guys had a mom-and-pop-type business cleaning and checking the oil on airport shuttle buses. They would do this stuff all night and have the vans ready for their first runs in the morning. (The site is on Stocker St., a standard shuttle route from downtown L.A. to the airport). The guys had one van door open with the stereo blasting, and because of the late hour and the altitude of my house, I could hear it perfectly, in violation of the LA Noise Abatement Laws, which specify that no amplified music system may be heard more than 150 off the property, whether public or private. I called the LAPD non-emergency number, they dispatched in about 10 minutes (I saw the car arrive and read those guys big-time), and I never heard those guys again, despite their continuing to use the site for that business for another year afterward. If you called 911 for something like this in L.A., you'd be laughed into humiliation. 911 is for the real stuff -- life and/or property in immediate danger. (Incidentally, during the riots, it typically took 5-10 minutes to get DIAL TONE, and another 20 to get to 911.

On that morning, tickets to a Garth Brooks concert went on sale and there was much congestion as people tried to place orders. A Dr. Hardy, of Tulsa, observed his wife was having a heart attack and, after starting CPR, tried to call 911 to summon an ambulance. What he heard was a busy signal. Dr. Hardy said that he repeated dialing 911 seven or eight times before finally getting through. He said that he really didn't know how much difference the delay caused in the outcome of the event, but valuable time was lost. A spokesman for Southwestern Bell explained the dilemma of the economics of providing enough capacity to handle large loads as opposed to normal activity. It seems to me that a sensible remedy to this and similar problems around the country would be to program the system to start dropping calls, if necessary to free up access to 911. Would this make people mad? You bet it would, but it is still better than trying to dial the standard emergency number, only to get a busy signal. The algorithm, here is simple. John Q. Public just dialed 911. Are all circuits busy? Knock off the first one that isn't from or to an emergency service. Martin McCormick WB5AGZ Stillwater, OK O.S.U. Computer Center Data Communications Group [Moderator's Note: The problem is *NOT* in deciding how to handle a 911 emergency call *once you have identified the call and know it is to go to the police.* The problem comes up in first identifying the call. Let's say ten phones on my desk are ringing at one time. One is my brother telling me the building is on fire and to flee for my life with the cats, etc. Another phone call is from a friend inviting me over for pizza and beer. When I get the 'house on fire' call, I know what to do with no further delay. The question is how do I know which ringing line to answer *first*? Should I hire ten people to stay there and answer calls in the event ten come at one time just so I'll be immediatly notified that the house is on fire? Phone systems are the same way. How many calls should be dealt with at the same instant in order to prevent the possibility that an emergency call will receive delayed handling? What happens if I have the ability to deal with that many then I get that many plus one more? Typically the ability to deal with 10-12 percent of the subscribers at any one time is more than adequate -- and that is during the busy times of the day. Maybe five percent of the subscribers (big maybe) want to use the service at the same time during off hours. How much should telco spend (and you the subscriber pay) to have the essence of a 'non-blocking' switch, if there is such a thing? The modern CO does not know the difference between one off-hook and another *until it finds time to go and get the caller's request.* At least one advantage of the old manual phone system was that a steadily flashing lamp on the switchboard meant a routine call; a rapid off/on flashing (because the subscriber was tapping the hook rapidly) would usually catch the eye of an operator who would then go to that one next *presuming it to be an emergecy*, and giving hell to the subscriber for flashing like that if it was not. (A rapid blink-blink- blink of a light on the board was universally accepted to mean 'oper- ator, talk to me now this is urgent.').

Most telephones in this country are still not capable of magnetically "reading" even the current calling cards. So unless you plan on replacing most of the telephones in the nation, or making the stored-value cards unusable on any phone without a card reader, the protection against fraud largely goes out the window; there's still going to have to be a number on the card for people to punch into older phones, and "shoulder-surfing" will still work just like it does now. In fact, I would wager that your protection from fraud would actually *decrease* under these circumstances. Under the currnt system, if someone steals your card number and rings up fraudulent calls, you can generally get the charges reversed; with fraud on a stored-value card, the providers would probably adopt the same policy that many providers of debit cards do now ("if your card or number gets stolen and all the money in your card gets drained, well, sorry about that"). Also, unless you want to further modify every phone in the country so that they're capable of *writing* to the cards too, the privacy advantage is going to be eliminated as well; since the phones won't be capable of recording usage onto the cards, the cards' value will have to be stored in some centralized database somewhere; and since that database is going to have to be provided with at least some information about where you're calling from and to in order to calculate the billing info, it will be capable of keeping records just as detailed as those kept now (where you're calling from and to, when you're calling, for how long, etc.). I suppose the phone company could be legally required not to record this information for stored-value-card calls, but that would completely blow away your protection against fraud. ("Well, since we have no way of knowing when or where those calls were made, we have no way of knowing whether they're fraudulent or not, so we'll just have to let the charges stand.") One other personal problem I have with stored-value cards: they require payment in advance, which may be okay for those who use the cards regularly, but is a pain for those like me who only carry a card in case of emergency or running out of change. Why should I give my long-distance carrier an extra $5 or $10 of my money to take care of, on the off-chance I need to make a calling card call someday? > Also, since it is a stored value card, other carriers would > have no incentive to honor the card (they won't get paid), so they > could try to vandalize the card or more likely just reject it. Thus, > protection from AOS overcharging. This is about the most Pyrrhic form of "protection from AOS overcharging" I've seen in a while. Are you saying that you'd rather have a phone try to erase your $50 worth of stored value than to overcharge you for the call? As long as we're updating every phone in America to deal with these cards, why not just encode the carrier choice into the card? You would pick up the phone, insert your card, and then dial the number; the phone would read the carrier code from the card and automatically select the proper carrier, without any of this 10XXX nonsense. > Of course, certain federal agencies won't like [privacy], so > Congress will have to pass a law requiring that > (1) each phone record its number and time of use on the card; and > (2) that each buyer send in his/her used cards with proper identification. > Failure to do so would result in a $10,000 fine per card. If you're going to joke, try to at least joke plausibly. :) "Oh, someone stole your wallet and your $100 stored-value card? Gee, that's a shame. Well you're out that $100, and since you won't be properly returning that card, you're out another $10,000 too." Besides, unless you really do intend on replacing every phone in the nation, I don't think the government will have any problem getting that information, since as I described above, the "stored value" will probably wind up implemented in a central database rather than on the card itself.

The DTMF tones are the same the world over. Unfortunately, the RJ-11 wiring patterns are not. On a 4-lead RJ-11, in the US pins 2 and 3 are used for tip and ring. In the UK pins 1 and 4 are used. You will therefore have to make up a line cord with leads 2 and 3 at the modem end going to pins 1 and 4 at the wall jack end.

Details were gleaned from a phone conversation with Mr. Tay Kim of Ameritech, who added that extra volunteers were welcome -- see restrictions below. I have no connection to Ameritech.) I've been offered a chance to participate in a long-term test of Ameritech's Personal Communication Services, which is essentially a cellular-phone type of network, but uses digital-transmission radio frequencies between the user's portable phone and local transceivers. I'm taking the liberty of calling it a "cellular" phone network to save explanations, though they themselves do not use the term. Ameritech, one of the Chicago area cellular providers, is conducting an 18-month test of various prototype telephones with several hundred people in the area of downtown Chicago, the Lincoln Park area of the city on the north side, and the suburb of Arlington Heights, to the northwest beyond O'Hare Airport. The Personal Communication Service, or PCS, consists of a very small handset resembling a typical cellular phone, though without the large battery pack, cord, etc. A short antenna of about 5" is used, with the flip-type handset having a pivoting cover holding the microphone, closing over the keypad. The phone transmits a digital signal with 10mW of power to a radio transceiver located on some nearby (two or three city blocks or approx. 1/4 mile) building or other high point, where it connects to the normal telephone system. The phones generate true DTMF for operating voice mail systems, etc., at the called number. The test areas have been populated with small transceivers consisting mainly of a box with a 12" antenna connected to AC power and a phone line. Ameritech is now rolling out various prototype telephones to test this system over the next 18 months in the area I described. They're recruiting people for the test in various ways (I assume); I was approached at the Arlington Heights train station on my way to work. You're asked to fill out a short questionnaire on your daily activities and phone usage, and mail it in. The results are tabulated in a database, and people fitting the profile (mainly by living and working in the test service area) will be given the phones to use. The first month of local calls will be completely free; following months will be charged approximately 25 cents per call or less (one portion of the test is apparently on varying fee scales!). Long distance calls will be handled by Sprint at their normal billing rates; alternative LD carriers may not be selected. LIMITATIONS: I was told that these phones are intended primarily for people on foot, or otherwise NOT traveling rapidly from one area to another. Using the PCS in a car or steel-framed building may or may not work; however, if it does work in your car, you're advised to pull over and stop, since the handoffs cannot keep up with car speeds. Walking-speed handoffs are intended, and you will receive an out-of-range warning before you lose a call by blundering out of the test area. Due to present technical limitations, the phones cannot take incoming calls. The prototype phones will be configured in different ways, most notably that some will permit hand-off from one transceiver to the next, but others will not. I was told that this is an effort to determine whether the hand-off capability is really necessary as a standard feature, since these phones are intended primarily for foot traffic. The only charges billed to the user will be for calls made after the first month (and any long-distance calls made IN the first month). Ameritech gets the phones back at the end of the test period, and will issue refunds for lost calls or poor quality connections if you have difficulty. IF YOU WANT TO JOIN IN THE TEST: You must live in Arlington Heights, the Lincoln Park area of Chicago, or downtown Chicago, and you MUST NOT be a member of a telecommunications company (unless it's Ameritech, I'll bet :-). Call Mr. Tay Kim or one of his associates at (800) 640-6472 for details. He told me that they are a small group in charge of running the whole test; in fact I discovered that he was the one who'd handed me the brochure at the train station, after which he'd rushed back to his office to field calls at the 800 number, plus he appeared in the glossy brochure handout posing as a commuter at the train station. A small group indeed! All told, this sounds pretty interesting, despite the current limitations. Biggest danger I can think of is adding to the number of bozos who babble into portable phones at the top of their voice in crowded areas when others are trying to concentrate, causing others to search around for large heavy objects to throw, but I think I can behave myself. If there's sufficient interest (and they deign to issue me a PCS phone), I can post a progress report as things develop. Disclaimer #2: Speaking only for myself, not Datalogics or Ameritech.

Darcos & Company" <0005066432@mcimail.com> Subject: AT&T Doesn't Like MCI's Ads New Ads Heat up AT&T-MCI Rivalry By Kent Gibbons The Washington (DC) Times (July 21, 1992-Pg C1) AT&T and MCI's war of words is getting personal. The newest TV commercials for AT&T's long distance rates attack the ethics behind MCI's recent spots promoting a new international calling plan. American Telephone & Telegraph Co. says MCI used unfair comparisons to claim savings of 45 percent or more off AT&T's rates. MCI Communications Corp matched its "Around the World" discount rates against AT&T's basic rates, rather than its cheaper "Reach Out World" discount plan for international calls. "Blatantly deceptive," said AT&T spokesman Jim McGann on behalf of the nation's biggest long-distance company. "Fair," countered Debra Shriver of Washington-based MCI, the No. 2 carrier. Most AT&T customers make their international calls on the company's basic plan, not "Reach Out World," Ms. Shriver insisted. Besides, she said, most of AT&T's advertised discounts compare with AT&T's basic rates. "If they've been comparing their own rates to [basic] dial-1 rates, why can't we do it?" she said. "How can that be fair?" Mr. McGann said of the MCI ads. "You've got to compare comparable plan to comparable plan. If someone makes a lot of international calls, it would make sense for them to sign up for 'Reach Out World'. For example, an MCI spot claims a call to France on its new plan would save 57 percent against AT&T's basic rate. Part of that savings comes from designating one foreign number as part of MCI's "Friends & Family" plan. For any other numbers in France, AT&T says, the savings against its international discount plan would be 1.6 percent. Stoking the fires, Mr. McGann called reporters yesterday about his company's ads, which first aired over the weekend. AT&T also provided videotapes and transcripts. AT&T and MCI have never hidden their mutual dislike. MCI helped hasten the breakup of the telephone monopoly with antitrust lawsuits in the 1970s. And in 1989 the two companies sued each other with claims of unfair advertising. They settled out of court. MCI has always compared its rates with AT&T's, even erecting electronic toteboards to show the supposed savings MCI's customers have enjoyed over AT&T users. The latter's commercials have jabbed at MCI's popular "Friends & Family" plan, in which MCI callers get extra savings if they sign up other customers. Sprint, No. 3 in the long-distance market, has taken on both rivals. But the new AT&T ads aim squarely at MCI's credibility. "Do you judge a company's ethics by their advertising?" an off-camera voice asks a man in an antique restoration shop in one spot. Answering more questions, the man says the MCI ads promise 50 percent savings through "Friends Around the World" but says he did not realize the savings wer off AT&T's basic rate. Why doesn't the MCI advertising compare discount plans? "I think the answer is obvious," the man replies. In another commercial, a woman says the advertising would change her opinion about the advertiser. Ms. Shriver said MCI stands by its ads and has no plans to change them or lob an attack back at AT&T. ------------- Paul Robinson TDARCOS@MCIMAIL.COM or 0005066432@MCIMAIL.COM By the way, I have two phone lines at home, one is on MCI and the other is on AT&T.

At a hearing this week before the National Commission on Library and Information Science, CPSR recommended a privacy policy for the National Research and Education Network or "NREN." Marc Rotenberg, Washington Director of CPSR, said "We hope this proposal will get the ball rolling. The failure to develop a good policy for the computer network could be very costly in the long term." The National Commission is currently reviewing comments for a report to the Office of Science and Technology Policy on the future of the NREN. Mr. Rotenberg said there are several reasons that the Commission should address the privacy issue. "First, the move toward commercialization of the network is certain to exacerbate privacy concerns. Second, current law does not do a very good job of protecting computer messages. Third, technology won't solve all the problems." The CPSR principles are (1) protect confidentiality, (2) identify privacy implications in new services, (3) limit collection of personal data, (4) restrict transfer of personal information,(5) do not charge for routine privacy protection, (6) incorporate technical safeguards, (7) develop appropriate security policies, and (8) create an enforcement mechanism. Professor David Flaherty, an expert in telecommunications privacy law, said "The CPSR principles fit squarely in the middle of similar efforts in other countries to promote network services. This looks like a good approach." Evan Hendricks, the chair of the United States Privacy Council and editor of Privacy Times, said that the United States is "behind the curve" on privacy and needs to catch up with other countries who are already developing privacy guidelines. "The Europeans are racing forward, and we've been left with dust on our face." The CPSR privacy guidelines are similar to a set of principles developed almost 20 years ago called The Code of Fair Information practices. The Code was developed by a government task force that included policy makers, privacy experts, and computer scientists. The Code later became the basis of the United States Privacy Act. Dr. Ronni Rosenberg, who has studied the role of computer scientists in public policy, said that "Computer professionals have an important role to play in privacy policy. The CPSR privacy guidelines are another example of how scientists can contribute to public policy." CPSR is a membership organization of 2500 professionals in the technology field.

I never heard of a Bob Parsons -- if I do know someone by that name I certainly don't remember them, so I can't see how such a person would think they know me well enough to give my name as a referral. Well, I talked with the woman from MCI and she led me to believe I would be getting a much better deal with MCI than I'm getting with AT&T. She said I didn't have to sign anything, they would switch my service as soon as I got off the phone. Oh, one thing that did annoy me -- they asked whose name my service was in -- it's in my wife's name. The woman said they would have to put my new MCI service in her name too. Right off ... two strikes against them: they probably pulled the name "Bob Parsons" out of a hat. Second, the talked to me on the phone 20 minutes and then they want to put the service in my wife's name. It didn't matter to them that I'm the one who brings home the paycheck. Well, the clincher, the last straw ... about two weeks after I told the woman from MCI that I would switch even if the service wouldn't be in my name, a package from MCI arrived in the mail. Enclosed was a "MCI Long Distance Certificate." It said, "Pay to the order of MCI or the Telephone Company $5.00 and 00 cents." It said, "Sign and enclose this Long Distance Savings Certificate with your long distance bill." As you might guess, this was the heart of the scam. The woman from MCI said I wouldn't have to sign anything to effect the changeover from AT&T to MCI. Well, if my wife had opened the mail that day I would probably be an MCI customer now. Fortunately she asked me to open the mail and when I looked on the back side of that "MCI Long Distance Savings Certificate" I read this paragraph which looked and read much like a contract. It said: "This is to confirm that I want MCI to provide my long distance service and I authorize MCI to not- ify my local telephone company of this choice for the telephone number(s) listed on this form. I under- stand that I may choose only one long distance company for each telephone number. I also understand that the local phone company may charge a fee for this and any later change. Well, I called MCI today and told them I decided not to make the change. They actually asked if I was "signed-up." They asked this after telling me I wouldn't have to sign anything. I said, "No, I didn't sign anything -- I had the "MCI Long Distance Certificate" in my hand as I spoke. She said something to the effect that if that was true, then I wasn't signed up. She also said something to the effect that if I "disregarded the form" I would never be "signed-up." I think my point is that if this company taught their phone solicitors to be HONEST, if they told them to tell would-be new subscribers that, yes, they will need to sign a changeover form to effect the change, I (I mean, my wife) would presently be a new MCI customer today. I just want to relay one other observation which may help the folks at MCI make a better impression on their customers. When I called today and got their electronic operator, it said to press #1 if I was an MCI customer, to press #2 if I wanted to establish a new account with MCI, and to stay on the line if I was calling from a rotary phone. Well, choices one and two didn't apply so I stayed on the line. I stayed on the line about four minutes and no one answered. I hung up and called back. I pressed choice #2, for would-be new subscribers. Someone answered on the first ring. My point is that it appears to me that if they think you may be calling to establish a new account they want to talk to you right away. If they aren't sure if you want to start a new account, or if you are poor (poor people are probably the only ones who still have rotary phones), they take their sweet ol' time and they appear not to care whether they talk to you or not. Well, if the "solicitation" had been handled differently, if they said something like, "Mr. Safina, we are calling long distance users in your area today to let them know what MCI has to offer. Blah, blah, blah, blah, blah. Yes, we would be happy to put the new long distance service in your name. Yes, you will have to sign a form authorizing us to make switch you from AT&T to MCI," ... then I would have made the switch and would be an MCI customer today. I may be a little weird, but I think credibility is an im- portant issue. I think the facts should be laid out in black & white and every question should be answered with 100% honesty. I might add that I did call the Kentucky Consumer Protection agency today to register a complaint, but writing this message has given me enough of an opportunity to express my discouragement, so I will probably use the complaint forms they are send- ing me to protest the incessant "computer solicitations" we get here on a daily basis. On that note ... today I had the phone company put a block on our account so no one will be able to call any 900 or 976 numbers from our house. Some of the prizes some of these companies offer sound so HONEST that some family member may be tempted to inquire one day without asking for my approval. Well, thankfully big business still empowers the "little people" to some small extent. I was able to make that choice, to block calls to any 900/976 numbers. Well, I guess I left this long post just to see if anyone else has been "solicited" in the same manner as I was and whether or not they thought there was anything obectionable about how the solicitation took place.

One of beleagured Telkom's main problems appears to be a lack of the high technology needed to support the controversial 087 service,. Consumers, faced with ever increasing phone bills, continue to demand detailed billing in order to establish exact charges on their bills. The discontinuation of a subscriber's telephone service due to non-payment of the 087 charges is also a bone of contention. There is legislation in the US preventing telephone companies from disconnecting a customer's basic telephone service for failure to pay 087 service charges. However, South African consumers are not so lucky. Telkom, at this stage, lacks the ability to separate 087 calls and other telephone charges. This means if a consumer disputes charges on a telephone bill, he does not have the option of paying only for normal telephone calls without losing his telephone line. Neither do comsumers have the right to dispute charges for 087 calls and to have these charges removed from the telephone bill. Telkom also pays 087 service providers before collecting from the consumers, so Telkom carries all bad debt arising if consumers fail to pay high telehone bills. Testimony in a Senate Committee hearing in the US last year again indicated there was almost universal support for the requirement that consumers have the right to block 087 services (in the USA = 900). This service is provided free of charge at least once on request. South Africans will soon be able to block 087 calls on their service -- but at a price. It will cost people on an electro-mechanical exchange R20 (about $8) to block the service. A Telkom spokesman said the older electro-mechanical exchanges were not capable of recording details of calls made. Furthermore, the computer network needed for detailed billing was not available. ------------------------------ From: klopfens@andy.bgsu.edu (Bruce Klopfenstein) Subject: Digital Video-on-Demand in Dallas? Organization: Bowling Green State University B.G., Oh. Date: Sun, 26 Jul 1992 10:54:38 GMT According to the 13 July 1992 issue of {Television Digest}, USA Video wants to test a video-on-demand service this fall "using one of Southwestern Bell's two fiber testbed communities outside Dallas." The technology was tested in SW Bell's lab in St. Louis in June. A compressed movie can be delivered to the home in 3 1/2 minutes using the "equivalent of less than ten standard video channels for rapid delivery." USA Video has a research operation in Dallas. I'd like to learn more about this venture including what SW Bell's "fiber testbed communities" are. In addition, I'd like to create a current list of such projects nationally and will be glad to share the results with comp.dcom.telecom readers. Please feel free to send email directly to me.

The appeal did not block off all avenues of competition and access, so it appears that the service to be provided in the fall will be something of an FG-A type service (ie. dial a local or 800 access number, get Unitel tone, dial the Unitel account number then the destination phone number) and Unitel promises a 15% discount over Bell Canada/Stentor service. The service is expected to be provided in all provinces for which long distance competition was permitted (according to CRTC Telecom Decision 92-12, the landmark decision made last month). Meanwhile, 13th October 1992 is a tentative date when the appeal court (Federal Court of Appeal) will hear the arguments of Bell Canada, BC Tel, and other telcos against the details of the competitive access. Unitel warned that it may not remain in the public long distance market if the appeal results in unfavourable conditions for Unitel, though a further appeal through the Supreme Court of Canada is possible (the loser of this fall's appeal could take the next step in the appeal process).

Turner Subject: Two Experiences With BellSouth A friend of mine recentaly bought a house in Atlanta (Tucker GA actually). She only had three phone jacks in the house and they were wired with a hodge-podge of wiring, and connected to the old (123?) style demarc which was hanging loose from the side of the house. I decided to scrap the old wiring and replace it with twisted pair. I called the repair service and asked then to replace the demarc. The rep asked me if the phone were working, I said yes, but could they change the demark anyway. She said sure and that it would be cleared by Thursday night (less than 48 hours later). Thursday PM a very competant craftsperson showed up. Not only did he replace the demarc but even installed RFI filters at my request. He even installed a RFI filter on the second line when I told him it would be connected soon. (I will be using one of the rooms as an office when I am in Atlanta). He also gave me the loops specs when I asked him. Though he had not heard of ISDN when I told him unfortunataly the loop was to long (23.6 kfeet), he volunteered that there was a SLC that we could be served off of if that would work. I was impressed for a residental installer. I then put her jacks wherever she wanted them and wired the back to a 66 punchdown block (AT&T four pair cable and PDS jacks). From here I ran a single line back to the network interface and punched jumpers down as necessary (tring to keep the antenna system to a minimum as a AM station was faintaly audiable in the background before). The ends of the old wire were disconnected from the network interface coiled up, tywraped, and left laying in the crawlspace (the old wire wasn't stapled, but just laying on the ground) This worked fine for over a month until her phones went dead. SB sent a repairperson out who said my wiring was shorted and a piece of crap anyway. He also said he would have to disconnect it as I had used "Twisted Pair" wiring which was also crap and they were told to disconnect it since it didn't meet spec. He said I should go back to school and learn how wiring should be done. The cause of the problem was the coil of wire in the crawlspace that wasn't connected to any thing, plus I had probally shot a few staples through the wire. (Any one who has ever used a T17/T25 or even a T75 knows that is a virtual impossability). He refused to believe her when she told him the wiring had worked for several weeks, and he assured her that whether she knew it or not I had worked on the wiring that day. (I was several hundred miles away). I've stopped by my house, picked up my megger and am heading to Atlanta in the morning. If there is a problem with my wiring, I will apologize to the net, but right now I have a very low opinion of opinion of SCB. GTE is often called Graft, Tape and Extort; Gross Telephones Everywhere; Great Telephone Experiment; Contel, the sunshine phone company... as long as the sun shines, the phones work fine; REA sub'd companies, Ripoff Enhancement Artists. John calls PacBell PacHell.

The HP Kittyhawk Personal Storage Module combines miniaturization with the cost benefits of conventional disk-drive technology, according to Hewlett-Packard. The PSM can be used in a number of applications, including cellular and other communications products, palmtop, pen-based and sub-notebook computers, printers, facsimile machines, medical equipment and digital-imaging devices. "Practically any product that uses a microprocessor becomes a candidate for the Kittyhawk storage module," said Bruce Spenner, general manager of HP's Disk Memory Division. The Kittyhawk can store the equivalent of more than 14,000 typed pages, Hewlett-Packard noted. For the cellular industry, the disk drive will be able to store text messages once cellular phones become more advanced, said Randi Braunwaler, a marketing communications representative at Hewlett- Packard. "We're thinking real futuristic here." The disk drive also could be used to receive voice mail in traveling salespeople's personal computers, Braunwaler added. The disk drive -- touted as the world's smallest -- measures 0.4 inches by 2 inches by 1.44 inches, and weighs about one ounce. It was designed with HP's calculators in mind. The unit can withstand an operating shock ten times that of larger 1.8-inch and 2.5-inch disk drives, the company said. "Today's 2.5-inch and 1.8-inch drives are limited as storage solutions for new generations of mobile computing devices because they are too big and too sensitive to shock Spenner said. Evaluation units of the Kittyhawk are available for $450, Braunwaler said. When mass production begins this fall, the volume OEM price is expected to be $250.

The full cutover follows a transition period since April 15, 1992. The country code 37 for the area of the former DDR (GDR) will not longer be valid. All areas in the eastern part of Germany already use new area codes starting with 3 for calls from West to East and for international calls. For calls within the eastern part of Germany the new area codes will be introduced between July, 1992 and the end of 1993. This will complete the reunification of the German phone network. By the way, when would the country code 37 be available again (e.g. for the new countries in Eastern Europe)? Is there a waiting period before 'reuse' of a country code?

Date: 26 Jul 92 01:46:46 PDT From: friedl@mtndew.Tustin.CA.US (Stephen Friedl) Hi telecom.folks, I use a carphone from PacTel Cellular here in southern CA, and it turns out that I *never* receive calls. Rather than give out my cellphone number, I give my customers my pager number (which they need anyway), and when they page me while on the road I make an outgoing call. I have no idea what my phone's ringer sounds like :-) Anyway, a friend of mine says that cellphones engage in sporadic "here I am" conversations with the local cell sites, presumably to limit how many cells have to light up on an incoming call. Since I will never receive a call, am I "wasting" resources in the cellular system by keeping my phone on when I am not using it? Would I be doing them a favor by keeping my phone powered off until I need to make a call? Note that my phone is wired into my car, so battery usage is not an issue like it would be with a handheld.

This is beyond the scope of what history.of.area.splits covers (it is limited to the implementation of N0X/N1X and to splits). For example, before N0X/N1X came to the DC area (also affecting the calling instructions throughout 301/703 before the 301/410 split), I saw several NN0 prefixes in the Maryland and Virginia suburbs. Until October 1990, there was seven-digit local calling among DC/MD suburbs/VA suburbs, so if you needed a new suburban prefix, you had to consider your own area code (301 or 703) along with a bit chunk of prefixes in DC and in suburbs beyond the Potomac. The history.of.area.splits includes the suggestion (NOT originating with me) that some sparsely-populated area codes could, when area codes become NXX form, hang on to 1 + 7D intra-NPA long-distance by disallowing NN0 prefixes, since the first batch of NNX area codes are to be of form NN0. ------------------------------ Date: Sun, 26 Jul 92 12:02:57 EDT From: dwn@dwn.ccd.bnl.gov (Dave Niebuhr) Subject: What is DSO?

I've never heard of this, but I thought I would ask here since I'm sure some of you guys have heard of this. I'll copy right out of the catalog: VOICE-DISGUISING TELEPHONE!

G516161 - Multi-Voice Phone was $19.99; SALE $16.88 Now for a couple questions. Is this as good as it sounds or is this just one big gyp? For $16.88 it's almost worth the risk to find out. Has anybody ever used these? How come these aren't on sale everywhere if they're so good? Can these really make my voice sound deep and gruff, and not like me trying to disguise it? Or does it sound like the TV interviews where they disguise the voice and it sounds like calling from Mars. Full of questions, aren't I? I've been getting a bit paranoid about the phone lately since I've been getting these calls where they hang up a couple seconds after I say "hello". I'm not too worried, cause it's still listed in my ex-roomate's name with no address, but still it's spooky when it happens. I'm tempted just to order it just to see if it works.

The features only work within my LATA. I can understand them not working for numbers that are not on SS7 equiped switches, but isn't the CLASS information passed on even through toll switches? If not will it ever be? I would like to add numbers in LA to my Priority Ringing list. Also it seems that repeat dialing works by attempting to retry the call every 45 seconds. I would think that this should work even through toll switches. When I asked about CLID I was told that Pac*Bell didn't have the technology yet.

I don't know a lot about telephony, but where I live, we can't bring in experts, so I learn what I need to to fix problems as they occur. And hopefully avoid more later. We have a small MITEL SX-20 switch (PBX? I don't know the proper terminology) which services our 20 or so extensions. MITEL no longer sells this equipment or makes replacement parts for it, and it's a real bear to get ahold of a real human at MITEL- they have a voice mail system that has to be heard to be beleived. I still see red. Anyhow, the remote operator display is on the fritz. This is a small display unit, approximately 8" x 8" x 1.5", with red LEDs to show number dialed, extension status, etc. It is meant to be located at the prime extension. I followed the troubleshooting instructions in the MITEL book, and the display unit appeared to be dead. So I ordered another one. MITEL said they would have to wait until someone sold them one or traded one in on a new system, refurbish it, and send it to me. Eight months and $200 (not to mention probably another $100 spent on long-distance hold or bouncing around in that voicemail system) later, I now have the new display unit and it appears to be as dead as the first one. It does sport a "refurbished and tested" sticker. I suspect the motherboard is bad ... possibly the place where the remote display plugs in. Yet I am loathe to go through the long process of obtaining yet another part from MITEL. Does anyone out there have any experience with the MITEL SX-20 switch, and if so, can you be persuaded to comment on this problem? I really need that remote display, since it is how I program the system. Some upcoming changes will force me to need programmability. Thanks for listening!

I then asked her about the calling card surcharge. Surprise, she told me that the calling card surcharge was 100% absolutely waived for all calls while you are on ROA. I questioned this. I posed examples in the day and evening periods. She was insistant. Finally, not believing a word of it, and knowing I'd never get it in writing, (:-) I had her go check. Sure enough, during your 1 hour of midnight calling, the surcharge is waived. Other than that, it's just discounted.

Pat's insulted just about every other loyal sub-culture of Digest readers, now he goes after us (I wonder if Pat realized the irony in the fact that Cliff is also a ham, K7TA). Since "P Towson" isn't in the callbook, I wonder where you've gotten this second or third-hand knowledge of how much the hobby has "deterioriated" particularly due to the invasion of "CB operators." While I'm not going to say something stupid like, "you owe the net an apology," your non-specific attacks are ignorant at best, and insulting at worst. Amateur radio may have its problems, among them: - gradual aging of the ham population - anachronistic Morse Code requirements (only recently remedied) - loss of interest among younger techie-types in favor of other distractions like computers we are clearly far from dead yet. The contributions of people like Phil Karn, KA9Q (NOS TCP/IP software package), those in the Amateur Satellite Corporation, and the ham astronauts who flew in recent SAREX (Shuttle Amateur Radio Experiment) missions, are testimony to this. In the two metropolitan communities I have lived in (Washington, DC and Omaha, Nebraska), the amateur radio operators I have met (and the organizations they are members of) have been enthusiastic proponents of the hobby, leading by their excellent examples. Everyone involved in the hobby that I know of has been extremely friendly, helpful, and technically competent. If "CB'ers" have overrun the hobby, then more power to them, because the subtle peer pressure of the ham community has molded them into model amateurs. (Maybe they were chased off of CB due to their distaste for the radio anarchy that can be found in that service.). Perhaps Mr. Towson would like to step out from behind his moderated enclave and more specifically enumerate what he dislikes about our hobby. Paul W.

What I do dislike is the way some parts of the the ham radio spectrum have been usurped by unlicensed, uncaring people who (judging from their conversations, tone of voice and phraseology) were CB 'enthusiasts' in the past. I mean, I do listen to my radios. I hear them here in Chicago doing foolish and inconsiderate things: going up into 40 meters and sitting there tuning up. They haven't even the courtesy to use a dummy load. They sit there keyed up, playing music and acting like jackasses. My complaints are with the people who cut down the trees and burned the forest.

Darcos & Company <0005066432@mcimail.com> Subject: About MCI's LINCS ATC System MCI's LINCS to Connect Air-Traffic-Control System By David Field The Washington (DC) Times (July 22, 1992-Page C1) MCI yesterday unveiled the nuts and bolts or, rather, the fiber optics and multiplexers, of a communications system for air-traffic controllers that the company is providing under its largest contract ever. The Federal Aviation Administration project will be worth $1 billion to MCI Communications Corp. over the next decade, MCI's president and chief operating officer, Daniel F. Akerson, said yesterday. Some 50 MCI employees in the Tysons Corner [Virginia] area will work on the project, and the Washington-based company will award subcontracts to local firms, MCI's vice president for government systems, Jerry A, Edgerton, told a reporter. The project is called LINCS, for Leased Interfacility National Airspace Communications System. It is designed to prevent emergencies such as the September 1991 interruption to air-traffic control caused by a telephone problem in New York City. It will link 156 air-traffic control units -- ranging from major regional command centers to individual airport towers -- to flight service stations that give private pilots flight information. The LINCS lines will also get air-traffic controllers' voice commands to airplanes, carrying them over phone lines to remote radio transmitters, which then send them to planes. A phone outage on Sept. 17 -- caused, as it turned out, by a gener- ator failure -- forced the FAA to cancel 500 flights, stranding 37,000 passengers nationally and capping a long dispute over earlier phone failures. The FAA, the Transportation Department unit that runs air-traffic control, insisted that any company winning the contract would have to design a system with 99.999 percent reliability. That, Mr. Akerson said, was equivalent to one loss by the Washington Redskins in 5,000 seasons (counting pre-season games). MCI won the FAA contract to design a new system, besting American Telephone & Telegraph and Sprint Corp. In case of a major outage, LINCS will restore service in an average of 20 seconds, the company said. The LINCS system, to be installed in the Washington area by early 1995, will replace the FAA's existing collection of telephone contracts with a single system with backup or redundancy capacity. All the phone lines to be used by the FAA -- 4.5 million circuit miles -- represent about 3.2 percent of MCI's total capacity. MCI won the contract with an initial $558 million, three-year award in March, but a protest by Sprint, a Kansas-based competitor, delayed the start of work. Mr. Akerson said the system will be in operation in the Seattle region by early next year, and LINCS will be installed in Southern California in 1993. FAA spokesman Richard Stafford said that LINCS for the Washington area, which is under control of a Leesburg air-traffic-control center, would be operational by the first quarter of 1995.

(Yes, I'm up past my bedtime.) The company I'm working for has a PBX with a mix of DID and non-DID lines. It's a "Meridian Mail" system, which seems to be Northern Telecom hardware with a Pac*Bell sticker on it, although that evaluation comes from a less-than-exhaustive analysis of the box on my desk. This company has an office in Switzerland (which wins my prize for most repetitive phone number -- country code 41, city code 41, phone numbers 41-XX-XX). Anyway, up until "recently" (some time before I arrived, but I've heard this from several different people), to dial an international call, you had to dial: 9 + 1 + 011 + country + city + number The less-than-Digest-level-telecom-literate people I've talked to were of the impression that Pacific Bell required the "1" before the "011" until recently. I assured them that it has never been PERMITTED, but they insist that this was how it was done, and have tales of reprogramming fax autodial lists to back up the story. The only thing I can figure is that it was something analogous to hotels where you dial "9" for a local call but "8" for long distance -- the PBX ate the "91" as indicating "grab a toll trunk," and then dialed the rest into the PSTN. Since the "1" has only recently been required for domestic long distance, it would at least be semi-coherent. Seeing the braindead stuff they do with much of the phone/computer system there, I wouldn't put such silliness past them. They also have some "secure" phones with some sort of encryption, I guess, for calling government people, but I haven't tried dialing 710, and only used "the black phone" once when I needed to call my answering machine. (The regular phones do the "blip" outdialing instead of matching my finger timing. Very annoying.)

I found the same tone on other prefixes in the local area (e.g. 882, the voicemail # I have,) so I wondered if the pitch was the same as the pitch of the tone one sometimes hears at the transition of long distance telephone calls. I decided to do so in glamor, and dialed the shortest possible pulse phone # I know, in pulse mode, just for the heck of it: 1 212 221 1111, and then it started to ring. I hit the click button on the handset to hang up the phone, but I must have hit it not quite long enough but long enough to evoke a reaction. What my ears heard from a distance as I was about to figure out what to do next was beyond description as I could not believe it, and brought to my eardrum I realized that it was quite within description, for now I could believe it, and I had to check to make sure I haven't been taking any drugs recently or be dreaming. Well, I am a pretty drug free person, hadn't defied that statistic recently, and I sure wasn't dreaming. What was I hearing? About, I'd say, 2^3 to 2^5 conversations going on at once! (Yes, I think in binary, so I'm sorry.) It was wild. I heard phones ringing (even some international puvvvvvvv--puvvvvvvv type rings,) people answering the phone in various languages, mostly american english, and wonderful voices from all over! It was definately an invasion of privacy, but since I could make out nothing but a few Hellos? and How are you doing!s, plus lots of nonenglish language, it was hardly invading anyone since I don't know them or don't know that I know them. The total amplitude of the connection was ever so slightly less than normal. T The quality of the mix of conversations was fairly good -- some were slightly louder than others, but not by much; usually conversations just starting (ring, ring, click Hello?) were louder than ones that had gone on for a while, but I was remarking on the absense of extra noises or hiss or blips or anything when of course a modem came on line (it was only on line for about 15 seconds -- presumably a FAX answering sequence or a quick credit check.) I heard some automated recordings, some business secretaries answering the phone, and I was quite amazed. I stayed on to be amazed at this wonderful occurrence, and then I stayed on to try to determine where the voices were characteristic of. I could not tell, other than there was a predominance of non-western, and more blandish eastern-US type voices. I know very little about the workings of the telephone system, but correct me if I'm wrong: I think I hit a bug in a digital D-A converter which decided to pick up conversations from ALL the channels attached to its multi-channel digit pipe, presumably not really caring that the D-A converter was giving me this interesting information because it thought I wasn't really connected or had a bug which thought that whatever I was doing was appropriate. Well, it was fun! Is this an oft occurrence, or did I hit a once in a life time thing? Quite amazing! Happened just half an hour ago. Oh, I'm not sure but I think the guy I'm houssitting for has AT&T as his main carrier. Actually, something I dialed recently gave me an AT&T recording, so that's a pretty good chance; can't always be certain though (I was playing with international #s just a few days ago.)

This is the sort of state-of-the-art-modem I would have had my group design were I still working in modem research at Gandalf Data. It has a two line by 20 character LCD display, menu-tree programming from the screen via four pushbuttons, and implements a whole bunch of CCITT protocols up to 14,400 v.32bis/v.42.bis, and v.17 FAX. Needless to say, it does both sync and async, and even has modes for use with cellular and satellite. (Presently, the operation modes are: v.33; v.32bis; v.32; v.29; v.27ter; v.22bis; v.22; BELL 212A; G3 FAX according to T30, v.17, v.29 and v.27ter; and most variants.) What does the display do besides allow you to program all the registers? Well, you can not only see the incoming connect speed, but also things like: - Signal-to-noise ratio - Received Carrier Power Level - Phase Jitter (p-p degrees with .1 deg resolution) - Frequency offset between TX and RX freqs (in .1 Hz res) - Round-trip echo delay in (1/2400 sec) ... and a whole lot more. After your communication session has finished, you can even call up (by an AT-command) a "Link Status Report" which will give you: - Chars sent; Chars rcvd; Octets sent; Octets Rcvd - Blocks sent; Blocks rcvd; Blocks re-sent; - Max Outstanding; Max Block Size; - Retrain requests; Retrains granted; Link duration; - T401 timeouts; T402 Timeouts; FCS Errors; - Round-trip delay; Xmtr under-run; Rcvr Over-run - Reason for disconnect. With the latest ROM revisions, it handles Caller ID, 4 different ringing codes, and the maximum speed is 16,800 baud. (They are working, I believe on 19,200 baud, as well as VoiceMail.) Finally, for the technically minded, it can even be supplied with X- and Y-axis outputs for a scope, so that you can see "eye" or "constellation" diagrams. There are three telephone receptacles for telco line connexions: One for a local phone; one for 2/4-wire leased-line, and one for 2-wire dial-up line. (The dial-up line even supports telco 1A-key system A- leads for lamp status control.) Lots of features have been left out of this little blurb to try to keep it as reasonably short as I can. Upgrades? Well, they are via a couple of 27C010-15 (1Mb) ROMs, and the binaries are usually posted on their BBS, or available via FTP or mail- server from various sources (including here). So, if you have access to a ROM-burner, you can do the upgrades yourself. Just had to let you know about this great little modem, in case you hadn't already heard. Anyhow, having said all of that, you can get most info (including TIFF- image files at 300dpi) from my mail-server. To save space, the files have been compressed with ZOO, which is available for most O/S from DOS to UNIX. (ZOO version 2.10 for DOS and for UNIX is available via mail- server from this site.)

C. Berkeley Open Computing Facility Pat compared the Usenet to Ham Radio. Got me thinking. You know, in every technical medium, things start out pure and sweet and exciting; as they become cheaper and better and more popular, they lose their purity; their excitement too. In 1956, nobody called long distance across the Atlantic. Anyone older than 40 remembers their first long distance phone call -- with an eye on the second hand of the clock, you spoke fast. That one phone call was cherished and packed with information. Not the same thrill today; not the same information content, either. And Ham Radio: When you could only communicate over morse code, messages were terse and more hams knew each other. Equipment was homebrew, or at least built from kits. Along with every other ham, you knew: - Morse code - soldering skills - basic electronics - message protocols - basic communications etiquette And each ham knew this in order to communicate, not just to pass a test. Intentional QRM and interference were rare. Today, you might need to know some of this in order to pass a test, but most hams get along quite well without. Result: oldtimers claim that the quality of ham radio has dropped. You hear of malicious hams interfering with others, anonymous kachunkers on repeaters, and private repeaters closed to outsiders. Other technological areas are the same way as well. Used to be that you froze when you went observing at a mountaintop telescope. You wasted no time on a clear night -- every minute was precious. You carefully developed a few glass plates, and delicately analyzed these, often under a microscope. Now, your astronomical data comes on a magtape, cdrom, or over a network. You might never look through an eyepiece ... especially if you use the Hubble Space Telescope, or any of the other astronomical spacecraft. You have more data, and better data too. But the thrill just ain't the same. Is the same thing is happening on the Usenet/Internet? When you had to know the TCP/IP suite and there were a few hundred nodes on the network, we mostly knew each other. It was a kicker to just get mail across the network or to ping another node. There were fewer flames and nastygrams. With today's million node network, it's a rare Usenet group without flamewars. You might recognize a few posting people, but how many have you met? Malicious intruders break into computers. Many postings have zero content. The thrill of receiving junk e-mail from Australia isn't quite the same as hearing a warbly CW signal on 20 meters which just might be a DX station. A telephone solicitor calling from 1000 kilometers away is just an annoyance -- yet thirty years ago, you'd be happy with a noisy connection from two counties away. Something's happening here. I'm not sure what, but BB King comes to mind: Thrill is gone. 73's Cliff K7TA stoll@ocf.berkeley.edu [Moderator's Note: You hit the nail squarely on the head. The thrill is gone -- it isn't *fun* any longer. And yes, Usenet is the same way. Most of the net is rapidly becoming unmanageable. Consider this Digest: When I took over, there were enough messages coming in to put out a Digest every two days. When Jon Solomon first started the Digest back in 1981, he would put out two or three issues per week most weeks. For the past year, messages have flooded in here at the rate of at least 100 per day and sometimes 200 per day -- this group alone. You may recall the CB radiio 'rage' -- when it was the latest thing back in the 1975-85 period. Millions of them out there, and finally so many people got so totally turned off, disgusted with the way it was so crowded and so full of junk they just quit. Even the FCC gave up any pretense of monitoring or trying to control 11 meters. Now the band is very quiet around Chicago by comparison. Only the real twirps are still out there at it. Watch Usenet and see if the same thing will happen in the next few years: A rapid increase in sites and traffic (even more than now!) then suddenly a lot of places just pulling the plug, at least on net news when they get tired of it. PAT] ------------------------------ Date: Sun, 26 Jul 92 15:09:48 PDT From: aimla!ruby!rudholm@uunet.UU.NET (Mark Rudholm) Subject: Re: CLASS/ISDN In article Jon Baker of AG Communications Systems responds to J. Higdon's discussion of the lack of CLASS/ISDN offerings from the GTE LEC: > The GTD5 has offered SS7 and CLASS services for about 4 years now. > All of the GTD5's in GTE West are, most definitely, without a doubt, > 100% certain, capable of providing SS7 and CLASS features. > When, and if, these services are deployed in your area is dependent on > the local telephone company (in this case, GTE West). ^^^^^^^^ Mr. Higdon lives in California, as do I. The last time I checked, the GTE company that is a pathetic excuse for a LEC in California was called "GTE California," not "GTE West." I won't go into the details of the kind of "service" they offered me (NO CANCEL CALL-WAITING, 3-WAY THAT SOUNDED LIKE 7448, MASSIVE OVERCHARGES, INCOMPETENCE AT EVERY LEVEL) because I think we all know. When I was "served" by GTE CA, I was on a DMS100. I know that this is a very good switch because I've been on one that was in use by Pacific Bell and it worked beautifully. I'm also convinced that the product made by Mr. Baker's company (the GTD5) is an excellent one as well, I just don't think GTE CA sets them up properly. Now that I'm safely back in Pacific Bell's territory, I have some news on the CLASS features that they started to make available last week. I ordered all three that are available: Distinctive Ringing, Selective Call Forwarding, and Last Call Recall. All of them are limited to work with SS7 equiped INTRA-LATA switches (NO GTE CA). Last call recall simply notifies you, via a distinctive ring, when a busy phone you want to call becomes available. It also works as a "redial" for calls that were successful. Distinctive Ringing and Selective Call Forwarding allow you to maintain a list of ten phone numbers that ring your phone distinctively or are selectively forwarded. An interesting feature of the editing utility used to maintain these two lists is that you can add to your list the last person who called you. Of course, when you review the contents of your list, the entry is just labeled "private" so there is no way to learn the number of the person who called you. But, if you try to explicity add a number to the list that is already in a "private" entry, you are told that the number is already on the list and all future references to the once private entry become the normal, non-private. So if someone calls you and you have a pretty good idea who it was but want to be sure, you just go into the list editor and add the last number that called you and then attempt to explicitly add the number you suspect called and you can learn if that was in fact the person who called or not. In fact, you can verify as many numbers as you care to key in. It's certainly not CALLER-ID but it isn't without its usefulness. Speaking of CALLER-ID, I really think that Pacific Bell and GTECA have the wrong idea. I do not think that universally available blocking will severly reduce the attractiveness of this service. The LECs seem to think that if blocking is available, it will neccessarily always be used by callers. Think about it, not ALL calls are harassment calls. Think about the calls you make, how many of them do you want to make anonymously? Personally, I can't think of any. When I call my friends, I WANT them to know it's me. When I call businesses, I usually end up giving them my phone number anyway verbally, which is, mind you less reliable data transfer. Also, when I call friends that I speak with frequently, I wouldn't have to leave a message on their answering machine at all, I could just let it capture my number. Not only would that be just as good as the message "Hi, it's me, gimme a call," but it would be FREE. It seems as if ALL the CLASS features have been installed on my switch (1AESS 213 WEbster 0)but are just not active because I get a seconday dial-tone when I dial *67. Also, when I dial *69, *57 etc. I get "the service you are requesting is not available on this line" rather than the "we're sorry you call cannot be completed as dailed" that I get on all the unused *NN codes. It is for this reason that I am quite convinced that Pacific Bell's rhetoric about "studying the financial feasability of offering Caller-ID before we decide to offer it" is just a ruse to get the CPUC to change the blocking requirements. I hope the CPUC calls Pacific Bell's bluf by just saying "Fine, don't offer it, lose a potential $5.95 per line." If the CPUC did that, Pacific Bell would find Caller-ID quite financially feasable regardless of blocking requirements rather quickly I'm sure. I know a lot of people's initial response to Caller-ID is "oh no, that's terrible, I'm just going to prepend all my calls with *67," my initial response was the same, but then I gave it some thought. Too bad Pacific Bell and GTE California refuse to do the same. Mark D.

I thought that the GTE horror stories were bad things that happened to other people. Well I just got a taste of how bad it can be. GTE switched my long-distance carrier from AT&T to ALLNET. I have never heard of ALLNET and I am sure that I did not authorize this. I am deeply grateful to AT&T for immediately sending me a notice that this had happened. I had just received my GTE bill so I would not have noticed the change until a month later. Then I would have found that all my LD calls were billed at an exhorbitant rate by ALLNET. Pretty sneaky if you ask me. But thanks to AT&T's letter I found out only a few days after the change. I made a couple of LD calls before then and I won't find out how much they billed me until next months bill. I authorized AT&T to change me back. AT&T said that GTE would bill me about $4 for the switch but AT&T would give me coupons for reimbursement. I read the letter from AT&T at 6pm Friday evening. Since GTE is closed on weekends I had to stew till Monday morning to vent my fury. When I finally got through to GTE's order center (over 10 minutes on hold) they said that I had been switched to ALLNET but they could not say why. They said that they could investigate this and I urged them to do so. They also said that ALLNET sends them magtapes with changes created by their "Automated Calling Program" which calls people and registers their answer as acceptance or denial. I never accepted anything and I always hang up on automated telemarketing systems. I thought that they were illegal now anyway. GTE said that they would waive the surcharge for switching me back to AT&T (how nice) and that I could call them next month to complain about the ALLNET charges. They said that it would take five business days for the change to take place. I guess that I will have to dial 102281 till then.

This is a little used back road which was reportedly once popular with the moonshine crowd. The road is so isolated that there aren't even power lines or indications of burried cables running along side most of it. The line in question starts in Florida where the power line ends. It is two bare copper lines hanging on glass insulators. When I first noticed it, several years ago, I assumed that it was an old and disused line and made a mental note to check for insulators around any downed poles. But over the years, I've seen some of the old square cypress poles replaced with modern penta treated pine poles so it's being maintained. It terminates in Florida on a pole with a metal drum the size and shape of a large juice can. The wires go into the can and two standard insulated drop wires emerge which cross the road and head off toward a fancy plantation house behind a locked gate. The line follows the road for about five miles into Georgia. It then takes off into the woods where it seems to head toward a cluster of buildings. I assume that it's some sort of private line. The poles are separate from the power poles which sit along side them for a short part of the route. The entire route may belong to the same owner but I doubt it as the line passes several homes on it's way to Georgia. OK ... now we can go back to discussing ISDN and digital celluar and such. [Moderator's Note: It is possible you saw an antenna for an ELF radio station. The length of an antenna is set by the frequency: the higher the frequency the shorter the antenna, and vice-versa. That's why police transmitting on UHF have little stubs for antennas on the back of their car and cell phone users have little ones also. On the other hand, a radio station like WGN, 720 AM needs a few hundred feet to get a good half-wave antenna, and WIND, 560 AM has four big towers over in Gary, IN for theirs. xtremely ow requency transmitters are good for use with submarines in the ocean ... very few radio waves can travel under water or through the earth. ELF waves can though ... but the trade-off is an antenna which stretches for miles at a time along the highway on telephone poles, etc. If what you saw is an ELF antenna it is probably a military thing, like the one in Wisconsin.

Our office REQUESTS this, so I asked our telecom lady about it. This is a common problem with Northern Telecom switches. Least cost routing is done from left to right. Consider these three combinations: 1. 9 + 0 + 2. 9 + 011 + 3. 9 + 1 + 4. 9 + 1 + 011 + The problem is that the local lines are presubscribed to one LD company, and there is a dedicated trunk to another. Since domestic operator assisted calls (example 1) must be given to the local telco, 9 + 0 must go to the local telco. Int'l calls are best handled (for quality) on the dedicated LD circuit, but the PBX doesn't have the capability in software to parse far enough into the number to make the distinction between sent-paid international and operator assisted domestic. The workaround is to have the subscriber dial 9 + 1 + 011 for sent-paid international. Apparently it's a common enough workaround that Northern pushes people to do it. That's the answer I came up with. Ed Greenberg | Home: +1 408 283 0511 | edg@netcom.com P. O.

If, however, two weeks goes by and you still want them and don't mind wasting $0.58, try me again. And please send a big SASE (requirement) - this "packet" is pretty thick and I've had trouble stuffing regular (#10?) envelopes. (2) I noticed -- like someone else here in c.d.t. -- that my local COCOT keypad tones do not correspond to the standard DTMF pairs. Well ... let me rephrase that ... I have perfect-pitch so I know the frequencies are correct, but they're sort of "out of order", e.g., if I press "2222222" each press gives me a seemingly random but still valid (just not necessarily "2") DTMF pair. I'm gonna take my electronic DTMF box over to confirm what my ear's telling me. The question: Why? Is this some sort of fraud-prevention mechanism that I don't understand? Hmmm ... (3) A random note on Repeat*Call here in West Virginia: when I camp on a number that's inside my CO (I'm on a 5E) but that has been off hook long enough for the switch to remove battery voltage, instead of getting the desired behavior (i.e., call me back when they go back on hook) or a valid recording (e.g., the phone you're calling is off the hook and we're not going to waste our time queuing on it), I get something like "The feature you are trying to activate cannot be activated because the number is not in your local calling area" -- the message you get when you really do try to queue a call out of the area. More interesting: when I try to camp on a number two miles away but in the DMS-100 switch's area, I get trunk reorder. A telco employee (who was curious but slightly suspicious when I revealed knowledge that DMS-100 was a NT product and not AT&T) said she'd report them as bugs. (4) One of my customer's had a rash of the "answering machines calling people" syndrome which I rather quickly figured out: person "A" calls person "B". "B" is on the phone, so "A" queues a Repeat*Call on "B"s extension. At 4:00, "B" hangs up and immediately leaves the office for home. By this time, "A" has left for home, too. When the PABX finally comes through and does the triple-ring cadence on "A"s line to let them know "B" has gone, "A"s answering machine picks up, causing the PABX to ring "B", whose answering machine also picks up. Result: when "A" gets in in the morning, "B"s OGM is on his machine, and when "B" gets in, "A"s OGM is on his machine. People actually thought (PhD chemists -- mind you) that this was something sorta supernatural going on!

Then again, there is usually something new coming along: From: US1RMC::"deering@parc.xerox.com" "Steve Deering" 18-JUL-1992 Subj: IETF Teleconference Steve Casner and I would like to thank all the people who helped to pull off the 2nd IETF teleconference. Bob Clements, Ron Frederick, and Paul Milazzo spent long days operating the vat and dvc consoles and the video cameras, a generous donation of their time for which we are enormously grateful. The excellent local networking facilities were organized by John Curran and Jeff Schiller, and the on-site sparcstations were provided by Chuck Davin and Paul Milazzo. Van Jacobson and Paul Milazzo (there he is again!) stayed up late to generate new versions of vat and dvc in response to the new demands of such a large conference. Many people around the global Internet provided multicast tunnel machines to build the largest IP multicast topology to date -- at one point during the week, the multicast routing table included 90 separate subnets (i.e., LANs and point-to-point links, NOT including all of the subnets traversed by the tunnels), in 10 different countries. (I will post a map of the topology in a couple weeks, after I get back from vacation.) And many more tuned in to the audio and video -- there were proabably over 100 sites that showed up in the vat window over the course of the week (I hope someone else was keeping count!). To those of you who suffered less-than-acceptable audio/video reception, or who couldn't be heard when you tried to talk back, or who didn't manage to get hooked into the conference due to lack of software for your machines or unexplained failure of the packets to reach you or lack of response to your email queries, we offer our apologies and the excuse that we only had finite time and resources, at least some of which had to be devoted to other tasks (you know, like chairing working groups and sleeping). I hope you will all be able to participate next time. (Next time?? Oh no! Well, plans are already underway for bigger and better things at the November IETF, and many of the people who provided tunnel machines have expressed an interest in keeping the multicast topology up from now on, not just for IETFs. Stay tuned to the ietf list for further information.)

If we can get everyone to prepare slides in advance, and to use the same format, and to know how to draw the impromptu ones with a mouse, then this would be possible -- but that is highly unlikely. I guess the "next slide" function could include feeding a slide into a scanner which would then multicast it. You get into transport reliability issues here. > 3.

I had to go out of town for a couple of days and, of course, my vat monitor crashed so I don't have a total count. But, thanks to a memory leak in vat and a core dump gratiously provided by Steve Pink, I know that an hour before the start of the Thursday plenary there were 118 sites active (a list is attached). I suspect that by the start of the plenary another 50 or so sites showed up (vat crashed trying to add six new sites) and on various screen dumps taken during the Monday and Tuesday sessions I see 40-50 names that aren't on this list. So I'd say 200 sites for the week is a conservative lower bound. Having a live, Internet `chat line' that literally spanned the globe was a unique experience. For example, I was hacking alone in my office with the speaker on around 4am when someone in Hawaii suddenly said "Anyone here?" and, before I could even unmute my mike to reply, people in Melbourne, Toronto, Stockholm and London came back with "Yes, we're all here." A week of talking to people on the other side of the planet as casually as if they were just next door has left me with an incredible feeling of community and a whole new sense of how connected our world has become.

Steel wool is a bad idea, because pieces of it can come off and short things out. The pros often use a pencil eraser.

I'm confused by this comment. The original writer said that the caller tried to call 911 and got a busy signal. I thought that a "local switch overloaded" condition would have resulted in no (or delayed) dial tone in this case. If the caller got a dial tone, dialed 911, and then got a busy signal, it seems to me that the local switch's message is "I hear you. I acknowledge that you're dialing 911. I have no more circuits and I'm not going to boot anyone. Please call later, or drop dead, or whatever." Have I got this wrong? [Moderator's Note: No, in the above scenario you do not have it wrong. But consider whether or not it was a busy signal or a no-circuit condition or whatever .. not all users are sophisticated enough to know which is which. If 911 returned the busy signal, there is nothing telco can do about it ... cut off one emergency call in order to put through another? If it was a no-circuit condition, was the CO saying it had no paths open to whatever CO the 911 operates out of, or was it from some other circustance? I think far more often the problem is just not getting dial tone. Any stats available on where congestion occurs the most -- at what phase of call handling?

Ricketts <73670.1164@CompuServe.COM> Subject: Re: 911 Nightmare Our Esteemed Moderator replies to a post: > The modern CO does not know the difference between one off-hook and > another *until it finds time to go and get the caller's request.* At But it depends on what point during call setup that the busy was issued. If the subscriber dialing 911 encountered busy going off-hook instead of dial tone then I agree. But if a DTMF receiver was available to the 911 caller giving dial tone, then I see no reason why the originating CO cannot be programmed to initiate call setup ahead of all other call requests. If this means seizing the very next trunk to come available or even seizing an active trunk carrying a non-emergency call (as indicated by the call request being 911), then so be it. This reminds me of an incident years ago in Houston that I'm sure most long-time Houston telecom-types will recall: Sometime in the late seventies, a major blood collection agency (Houston Blood Bank or maybe the Red Cross) staged a telethon on *all* local television stations -- network, local-only, and PBS -- to call in and pledge to donate blood. It was billed in the local media as "The only show in town". An appointment time and location to donate was scheduled during the call. For the one hour that the telethon aired plus another thirty minutes or so afterwards, it was nearly impossible to place a call to/from any CO in the entire city. It was a major league gridlock. This was before the days of 911. Imagine needing emergency care during that 90 minute blackout.

To eliminate that type of hacking possibility, it is mandatory that the dialback portion of the modem call is originated from a different line. Therefore, if you have 'n' number of phone lines to be used for dialback, you require n+1 lines. It is required that the host system performs the dialback procedure in order to determine the correct line to use. It also has the added benefit in that system administration of the modem pool can be centrally administered by the system adminstration folks. > When performing dialback, it can call different dialback numbers > linked to different security codes.

AT&T makes a decent STP cable for use with their Premises Distribution System. Its intended for RS-232 and can be used for Token Ring, too. Others make a similar cable, including Belden and Columbia. I have not taken the time to carefully compare and match published specifications. AT&T's cable people told me that 10BaseT over STP is not uncommon. I have also run 10BaseT over STP that was originally for RS-422 use. Never thought it would work, but it works just fine. Ahh ... but we cheated: Bear in mind that I test the cable with a Microtest scanner prior to installation in order to confirm its ability to operate satisfactorily. In most cases, I have observed reliable operation of many type of STP at distances of 70 to 100 feet. If the cable does not have a good uniform twist in the pairs, then it fails every time. As does "quad" type (red-green-yellow-black) JK non-paired old style station cable. This attests to the robust functionality of the signalling format and today's 10BaseT equipment. I'm very partial to using STP or UTP over RG-58 coax. (But then again, I'm a 20 year veteran telecom engineer, what do you expect?) Note that the silver satin base cords (telephone type) used with 10BaseT Network Interface cards all to often to connect with the wall jack are not sheilded or twisted pair. They radiate and attenuate like heck, too. Use a twisted pair type base cord if you can. Non-UTP base cords will run 10BaseT 14 to 25 feet, FYI. UTP base cords have nearly the same characteristics of Level 3 (good qualty) UTP voice station wire, which will do 300 feet plus. Good UTP base cords are made by Homaco and Orrtronics, among others. Also: very few people know that EIA-468 compliant jacks and wiring/color code practice needs to be observed. If you need a catalog, Homaco has a nice catalog with 10BaseT stuff in it (they are in Chicago, and most telecom supply houses carry their stuff) AT&T, Orrtronics, Krone, Nevada-Western, Hubbell, Leviton, Suttle, Seimon and others all have good catalogs and suitable products, too. I use Homaco, Orrtronics, Hubbell and Leviton here. AT&T, too, but its a little more pricey. Why do I use these brands? I like the products, they are carried by several of the suppliers I deal with and they seem to be priced competively. Also, no one has been willing to offer me a large bribe to change brands... [grin]. I'd put in STP in a residence without hesitation. I'd also test the cable first. Either a Homaco patch panel or AT&T 110 type patch blocks would be in the wiring area. Perhaps termination of the 10BaseT cable directly in crimp-on RJ-45 plugs (to allow them to plug directly into the 10BaseT hub) would work, but I tend to associate that practice with "cheap and dirty" work, something I see all too often. Seems as though computer stores do not know how to install cable neatly ... I have to fix a lot of their installations. This advice is worth exactly what you paid for it ... be careful and you will be rewarded with a working installation, but you must do the homework.

This will all become moot soon. In what is called the "shared database", routing to proper carriers will be based upon the entire seven-digit 800 number. In other words, all carriers will be able to offer all prefixes. This should have been on line already, but as usual certain unnamed particpants have been dragging feet. However, it really is "just around the corner", so I would suggest making your carrier selection on the basis of merits and then get the phone number of your dreams when the shared database takes effect.

You're right that the NEC is just a model, as are most "national" codes (such as the Uniform Building Code.)

It is a bit more complex than "they just don't want to right now". Even when Pac*Bell decides that it will go ahead with CLID there are some conditions that the CPUC has imposed. The most significant of which is the requirement to "educate" the public concerning the ramifications of the service to all customers. This will require approximately a six-month media campaign to be completed before the first of the service is activated. As you know, GTE has decided not to play at all and will not be offering CLID now or in the future. It is also questionable whether the company will even offer any of the other features.

End-to-end SS7 connectivity means that every trunk over which the call passes uses SS7 signaling. The path from the originating end office to the IXC point of presence; the LEC/IXC interface in the originating LATA; the path through the IXC network; the IXC/LEC interface in the terminating LATA; and the path from the IXC point of presence to the terminating end office must all be SS7-signaled trunks. Currently, the LEC/IXC interfaces are virtually all MF-signaled, not SS7. Note that for CLASS (SM) features to work on an interLATA call, both the originating *and* terminating interfaces must be SS7. SS7 interconnections between LECs and IXCs are slowly being deployed; I've seen in the last couple of issues of {CommWeek} a Southwestern Bell legal notice of tariff filing of SS7 access arrangements, and I know I've seen other LEC notices in the past. It's getting there. > Also it seems that repeat dialing works by attempting to retry the > call every 45 seconds. I would think that this should work even > through toll switches. Repeat call, or whatever name the LEC has given it, doesn't retry the call; it requests the terminating switch to monitor the status of the called line, and when the line transitions from "busy" to "idle", the terminating switch sends a SS7 message to the originating switch. The originating switch then rings the calling phone (if idle), and when you pick up, re-originates the call. This requires end-to-end SS7 also.

Most (but not all) 911 systems use dedicated trunks from out-lying COs to a central tandem, in order to get ANI or be able to prevent disconnect. If you get "all circuits busy" or "regular busy", then you called during a burst of 911 calls. The system cannot tell how important your 911 call is (pressure sensitive keypads??), and will not drop another until an attendant ends a call. One could always argue that more dedicated trunks or attendants are needed, but would you really want to pay for it?? As I've mentioned before, the real 911 problem from the "Garth Brooks" mass ticket sale is not lack of trunks. It's lack of quick dial tone.

The reporter gave an example of a busy signal, but it is not known precisely whether the sound was recorded from an actual attempt at dialing 911, that morning, or was simply a recording of a busy signal used as an example of what one sounds like. The thought even occurs to me that the caller might have even heard a reorder signal since many people call that a busy signal. My idea of a system to shed non-emergency calls in order to free circuits for 911 is based on at least getting a dial-tone. It is quite true that if there is no dial-tone, the switch doesn't really know that you are there, yet. Most of the exchanges in Tulsa are now electronic and it would seem possible that they could be programmed to make room for 911 calls, assuming that they, themselves, weren't so overloaded that they were no longer capable of giving dial-tone.

While full SS7 deployment will enhance the performance of 800 and similar intelligent network services, it is not a requirement. MF trunking and FGD interfaces work fairly well. As far as who (read this as IXCs and LECs) is fully deployed and who isn't, the score card changes almost daily. My information (A little less than real time accuracy) is that most of the dominant IXCs are fully SS7, while the LECs run all the way from hardly any SS7 to well over 90% of their signalling on SS7. The internetworking of IXCs and LECs SS7 signalling is one of the current major tasks before the industry in the US. The FCCs 86-10 docket plays a major role in expediting SS7 deployment. Can (obvious proprietary issues here) anyone share current SS7 deployment stats?

As you suspected, your impression was wrong. :^). There are several ways other than SS7 for sending ANI information from a local exchange carrier (LEC) to an interexchange carrier (IXC). There has to be. SS7 is relatively new, yet IXC's have been billing for long distance without it. In order to return ANI to an 800 customer, then, the IXC only needs the billing number it got from the LEC. Caller ID, the residential service, *does* require SS7 as implemented.

Jee, I don't know; I thought 1-800 worked "really well" before SS7 existed ... :) In the beginning, 800 was implemented by setting up lots of switch translators -- the final destination was usually a number like NPA-015-2345, for Band 5 calls. Then CCIS 6 made possible the 800 database, and AT&T started using it to both screen for Band violations and to derive the destination number. This worked well until divestiture, when everyone (LEC and IXC) wanted 800 numbers and their own databases. The current scheme pre-allots 800 NXXs to carriers, and sends the calls to them with FG-D signaling (ANI, etc.). Each carrier has their own database(s) and scheme for accessing it/them. As a long-term objective of divestiture, the "industry" was to develop a means for assigning 800 numbers to carriers on a 10-digit basis, and provide a means to change that association. Bellcore's scheme for this is described in TR-TSY-000024, called "800 Number Services". In general, this uses SS7 from an End Office (EO) to query a database that will return an associated carrier and (possibly) a destination number. Where the EO does not have the feature, either FG-D MF or SS7 or ... can be used to reach a Tandem switch that can then query the database. If a non-LEC carrier is associated with the number, the carrier can be reached using FG-D or SS7 signaling. Much of the push for SS7 interconnection now is to reduce the "post-dial delay" associated with the FG-D signaling scheme combined with the use of a Tandem to do the query. For example, today's 800 call could go direct to an IXC from an end office, using about 22 MF digits. With TR-24 and a Tandem, there's 28 digits to the Tandem (in two stages), a query/response delay, then 22 digits to the IXC. That's roughly 3.5 seconds added delay in delivery. SS7 can cut that delay by querying directly from the EO, or using SS7 to the Tandem, or using SS7 to the IXC from either the EO or the Tandem. The current version of the FCC 86-10 ruling is designed to reduce the delay in two stages, while speeding up the availability of "portable" 800 numbers. > ... Are we reading in the above that there is not yet 100% SS7 > interconnects in the US? Yes and no. Calls in general will not use SS7 between the LEC and IXC TODAY. But most are interconnected with SS7 in some fashion in order to verify Calling Card numbers, line restrictions, etc. This was needed in order to comply with an earlier timetable for removing LEC access to AT&T's old line databases (CCIS 6 access). > IS it that 1-800, ANI and caller-ID are being done by some other > means (I'd have to do some learning here then.) or is it that the LD > carrier do use SS7, and only that some local links are not yet ? Caller-ID today is primarily restricted to intra-LATA SS7 connections (but CCIS 6 was used for some early trials). The current NXX-based 800 access scheme and ANI are available with MF signaling, but are also supported with SS7. Where did you get your information?? Al Varney - just MY opinion.

Are we reading > in the above that there is not yet 100% SS7 interconnects in the US. "Really well" being a loaded phrase, I'm going to avoid using it ... 800 services can be and are implemented without SS7 network interconnect between LECs and IXCs (and between BOCs and other LECs); in fact, 1992 being the 25th anniversary of 800 service, it is obvious that 800 service worked fine before the world even heard of SS7. What I suspect you're thinking of is twofold: 1. Current 800 service implements carrier selection by the "NXX" method, a.k.a. six digit translation in the originating LEC network. Each 800 NXX prefix is assigned to a single 800 service provider. The originating LEC end office or access tandem performs a six digit translation on the dialed 800-NXX number and uses that to route to the appropriate carrier (IXC if an IXC NXX, performs a database dip if the LEC's own NXX, reorder or announcement if some other LEC's NXX). FCC docket something-or-other orders what's commonly known as "800 number portability", wherein the 800 numbering space will be partitioned amond service providers on a seven digit basis instead of a three digit basis. This requires that the originating LEC network route on ten digits instead of six. Because this amount of information can't be stored in a switch, the originating LEC switch will (in most cases) route the 800 call to its access tandem, which will query a database (800 Service Control Point) to determine the carrier to which to route the 800 call. 2. Because an additional database query is being used in the originating LEC network, call setup delay will increase by a non-trivial amount. The FCC, in the same docket, therefore imposed fairly strict performance requirements (which are, I believe, a median time for calls to be delivered to the terminating LEC of less than 2.5 seconds by sometime in 1993, and a 95%ile time for calls to be delivered to the terminating LEC of less than five seconds by sometime in 1995). To meet these performance requirements calls for a fairly high level of SS7 implementation, both in the LEC networks and LEC/IXC network interconnections. (The IXCs internally are almost, if not completely, 100% SS7.) Therefore, to implement "800 number portability" requires high (although not 100%) SS7 implementation. > IS it that 1-800, ANI and caller-ID are being done by some other > means (I'd have to do some learning here then.) or is it that the LD > carrier do use SS7, and only that some local links are not yet ? Both. 800 calls are sent from originating LEC to IXC to terminating LEC via whatever signaling method happens to be in place. Wherever the 800 database query occurs, some kind of out-of-band signaling has to be available (SS7 in almost all cases today; historically, AT&T used CCIS - SS6 - for queries before SS7 was around). ANI delivers the Billing Number from the originating LEC to the IXC via equal acces MF signaling; this can then be carried through the IXC network if the network supports it, such as in the SS7 Charge Number parameter. It can then be delivered to customers which are directly connected to the IXC network (via T1 carrying either ISDN Q.931 signaling, or MF/DTMF which has been modified to deliver the billing number in a way similar to equal access MF). There is currently, short of SS7 network interconnect, no way to deliver calling party number or billing number from the IXC to the terminating LEC. Hope that answered your questions.

In our case, the CLASS features will not even cover the entire LATA (excluding the 707 area) initially. But what amounts to the nine-county Bay Area is quite a chunk of real estate. An area consisting of several thousand square miles is not my idea of a "neighborhood". But as I was reading the phone book in the hotel room yesterday morning in Reno, I was once again reminded that the whole world is not California. The book described "Custom Calling 2000" which is the entire litany of CLASS features. Yes, Nevada Bell (a Pacific Telesis company) offers Caller ID and no per-line blocking. Of course, it is Nevada, not California. For some strange reason, the state of Nevada does not find it necessary to pass laws that cover every single action one can perform in his wakeful condition. I saw people riding motorcycles without helmets (I would never do that, but it is nice to have the choice), people riding without seatbelts, and Caller ID. California, in its infinite wisdom, has decided that these things (as well as thousands of others) are not allowed. So a state that cannot even pass a budget on time (or at all so far this fiscal year) as required by law, can still dictate to its residents all of the things that they cannot have or do (for their own good, of course).

For origination queueing, your CO is sending a message via the SS7 network periodically to query the status of the target line. If it is busy, nothing happens, and it queries again a bit later. If it is idle, your line is rung; when you answer, the target line is rung and the call is considered complete. Thus, since SS7 messages are used to query the line status, this feature will not work unless there is SS7 connectivity between you and the target line.

It sends a message to the destination CO, via the SS-7 network, requesting notification when the called line becomes available. If the destination is not SS-7 equipped, or if the destination number is part of a DID group, even if the office is SS-7 equipped, then your request for 'repeat dial' is rejected.

For switches, the term DSO usually means Digital Switching Office (or maybe Digital Serving Office). This is sort of a generic name for such offices, of which the DMS- and digital ESS switches are specific instances. In the CLLI(tm) ("silly") code of Bellcore, COs are identified by City, State, Building and the "building subdivision" -- the latter is a code that identifies the "type" of switch and the specific instance within the building. For example, "Toll" switches are usually identified by "04T", where "T" is Toll Tandem and "04" means the 4th such switch in the building ("01" through "03" may have been retired long ago). The code "DS0" (not "DSO") is commonly used to label the first digital CO in a building. Bellcore has a whole list of rules for choosing the identifiers for switches and for all sorts of equipment. Analog ESS switches are subdivided by type; the No. 1/1A ESS switches are "CGn", with "C" specific to those switches. A "D" was for the 4-wire version of those switches, and "E" was for No. 2 ESS. There are so many digital switch vendors that Bellcore just uses the "DSn" for all DSOs. > Today, NYTel had a notification in {Newsday} that the company was > offering Enterprise DSO which carries both analog and digital signals > over fiber but no explanation was given as to what DSO was/is/does. Obviously, NYTel can use the "DSO" to mean anything it wants ... But are you sure it wasn't "DS-0", a common term for a 56/64Kbps channel within a DS-1 1.544Mbps "T1" line.

I bought one for $59; it plugs between the wall and my phone. I get to set a 4-digit code. When someone calls in, the phone doesn't ring; instead, this box picks up and prompts for an additional security code. If the additional code is entered, the box warbles. If not, it hangs up --- with no audible indication on my end that anything has happened. The only thing I can think of that would make it nicer, would be if instead of having the box warble, it actually generated real ring voltage on its output jack. It isn't line-powered, after all. Then you could put other telephony appliances downstream of the screening box. Still, I like it just as it is.

Organization: Northeastern Ohio Universities College of Medicine Date: Tue, 28 Jul 1992 03:30:53 GMT I've noticed that my Uniden cell phone sends out some sort of inquiry a few seconds after being swtiched on. That inquiry is something in addition to sensing of SERVICE AVAILABLE condition. Detaching the antenna makes the SERVICE indicator turn off immediately. Reattaching the antenna makes the SERVICE indicator turn on immediately. I have Cellular One as a carrier. In this area, Celluar One is an A service "wireline" system, I believe. The system seems to keep track of the last location of mobile sets until midnight of the current day. For instance, if you have automatic follow roaming turned on, it is cancelled each midnight. Ringing seems to go out to all cells in the last known serice area of the unit, as it is perfectly possible that the unit might have crossed cell boundaries since the last contact with the unit. You are correct that the mobile unit does periodically talk to the system. My unit makes some sore of inquiry every five minutes while it is switched on. The sytem doesn't waste too much bandwidth attempting to contact a mobile unit. When I dial my switched-off cellular phone, the system will generate approximately four ring-back tones before it switches over to an intercept recording saying, "The Cellular One phone you are calling is either switched off or out of the area." I'm not sure what the period inquiry is doing. The manual says that the phone will try to re-establish service every five minutes. Apparently, the phone expects to get an answerback from the system in addition to sufficient signal quality. If the phone has gotten an answerback from the a correct A or B system and signal level is maintained, it must presume it is still in the service area. The uniden phone I have also automatically adjusts its transmitter power between a few mW and three watts depending on the strength of the signal coming from the cell. The results of this can be interesting in marginal conditions because the phone will go to a full three watts when it can't hear the cell in the middle of a call. The cell, apparently having a much better reciever continues to hear the phone. I've had a number of calls where I can not hear the person I'm calling, but the person can hear me. All in all, I'd switch off the phone when you don't need it. This will keep you from getting junk calls and wrong numbers. The system probably has to ring all the cells, or least some number, starting in your last known position anyway. As a side issue, I've noticed that my cellular phone has yet to receive any sort of junk telemarketing call. I presume that cellular prefixes must be some magic taboo for telemarketers -- or it could be that since most cellular users switch off phones while out of the car, etc., that the hit rate is low enough that sequentially calling in cellular prefixes is a waste of time. My pager, on the other hand, recieves a lot of wrong numbers. My number xxx-5225, must be close to that of some local drug dealer. I get a lot of xxx-xxxx-911 displays on my pager. Usually about 23:00-00:00. The prefix is often in the downtown area. I've occasionally called those numbers out of curiosity. They've all been older women with noticable ethnic accent ... or they might be old ladies trolling pagers just to get a human with which to talk; naah.

You should also be thinking about WHAT information will be made available, rather than just "how much" of it. A monopolist provider of information will be able to select, and let flow, only that info which supports/does not hinder its purposes; but if there are many, independent suppliers in free competition, you WILL be able to get access to much more variety (not necessarily cheaply, if information of a given sort is costly to produce/gather and only has few customers; but the mechanisms determining this will be more economic than political).

Also is it possible to trace > calls from home, not the exchange? Scramblers of course vary but a common technique is frequency inversion, if we presume that the telepone bandwidth is 300 - 3300 Hz (mainly because I'm lazy) then 300 Hz is translated 3300, 3300 to 300 and 1800 stays the same. The technique is to ssb usb modulate the speech with e.g. 100 Khz giving us 100.3 to 103.3 KHz then ssb lsb demodulate with 103.6 giving us 3300 to 300 Hz. I'm told that this technique is only effective against casual listeners. Another technique is to encode digitized speech, CDMA is an example though for different reasons. Needless to say that these techniques require digital tarnsmission for reliability. Tracing from the home is not strictly possible, in the USA there are these newfangled caller ID devices. I have heard that NZ Telecom is now controlled from the USA so perhaps you'll get them soon. Ericsson market a facility in their AXE exchanges that allows the subscriber to indicate that they have received a call that they want traced and a printout is generated in the exchange. The effectiveness of this technique depends to an extent upon where the caller calls from but it is a very usefull facility. As it is exchange based however it is only useful for official type tracing, not casual curiosity. I would guess that most (if not all) exchange types have a similar facility.

What differences (power, signalling, connec- > tors, etc?) would cause problems? The answer is a qualified yes. You need to adapt connectors and power supply. I've looked at prices for this kind of things when I was there last March and you will be well advised to take not only your machine but your favorite telephone along. The cheap phone that sells for $15 in the US costs above $50 there. Household electrical mains is 220V/50Hz (as opposed to 110V/60Hz in USA- Canada). You can buy a 220V/110V transformer to put between line and your machine's plug (frequency shouldn't be a problem; most machines convert line power to DC). If your AM's power supply is one of the external, plug in, you are better off buying a power supply that does 220V-whatever (e.g. 9V DC) directly. Either the 220/110 or the power supply you can buy easily in Buenos Aires and other major cities in Argentina (and you are sure to be getting the appropriate plugs, which are skinnier than some european 220 plugs). Connectors are not very homogeneous. If you are just a bit inclined to do this yourself, I'd suggest that you buy here a couple of wall plates and screw-on modular connectors, and install them wherever you want to put your telephone instruments (as my RBOC calls them). These usually are ridiculously expensive there. Or you can just strip one of the ends of your modular cable and put one of the horrible, bulky connectors that don't require special tools to assemble. Signals et al.: some switches have the annoying habit of returning a fast busy quickly after your caller hangs up. That may induce your machine to keep on rolling and not hang up for a while. This is taken care of by setting the CPC switch appropriately or putting the machine in a fixed recording time (as opposed to voice actuated, "vox"). Miscellaneous: - dialing is pulse only, no DTMF. Which means no touch-tone only phones, and if you have a "remote-less" remote-controlled machine you may want to buy one of those pocket tone diallers. - short power outages are frequent. If your machine stores the outgoing message on a chip, make sure it can retrieve it from tape after a powerdown. - long distance calls are very expensive, compared to the US *and* Canada's. Find out about plans like USA-Direct (available dialing 001-800-200-1111) from many phones before you leave. - some (many) COs still don't have direct dialing abroad. This includes otherwise desirable residential areas, so inquire. The above 001 ... number is not accessible in those areas either. Hope this helps ...

Correct! The maximum value of a stored value phonecard is (in the Netherlands at least) about US $ 14.--. Really, that is much less than I usually carry around in cash. Cards are available in much smaller values too. A stored value card is much easier than using coins, because: - I don't always carry sufficient coins of the right type. - The phone has a much higher probability of not getting broken into, because there is no cash inside, therefore the stored value card phones more often work. > Also, unless you want to further modify every phone in the > country so that they're capable of *writing* to the cards too, the > privacy advantage is going to be eliminated as well; since the phones > won't be capable of recording usage onto the cards, The phones can ERASE the card, not write on it, they don't have to. > the cards' value will have to be stored in some centralized database > somewhere; No, no, no. The phone can recognize that a valid card is inserted and reduce the value by erasing part of the card. No central database (or any other type of database) needs to be involved. The phone cannot distinguish two cards of the same purchase value if they happen have the same number of remaining "units". > One other personal problem I have with stored-value cards: they > require payment in advance, which may be okay for those who use the > cards regularly, but is a pain for those like me who only carry a card > in case of emergency or running out of change.

Indeed, this could be done. But having several providers of phonecard phones does create a nontrivial problem. The phones must be able to recognize several brands of phonecards and -- in some secure and indisputable way -- record how many units they have burned of each type. The owner of the phone must charge the issuer of the card for that number of units. I believe that this can be done.

Date: Tue, 28 Jul 92 21:58:11 GMT For one-time and emergency situations, I have always had good luck doing this: Make a modular cord with alligator clips on the red and green wires and plug it into the modem. Unscrew the microphone from the telephone and clip onto the contacts for the microphone. Caveats: - Phone must have a carbon microphone. Most that unscrew are. Most fancy new phones with lots of buttons aren't. - Modem probably cannot be line powered, although I have used cheap line-powered speakerphones like this on our old digital key system at work. - The modem cannot answer or pickup/hangup the phone, so this is somewhat manual involving taking the handset off/on the cradle. - If the phone system accepts only pulse dialing, you'll have to dial via the phone. Even though most modems can pulse dial when connected directly to the line, they can't with this arrangement. Tone dialling should work if the equipment on the other end is compatible.

A number of years ago, the cable that follows a road to one of my mountain top sites was damaged. It failed during some major flooding and earth movement about a decade ago. GTE's "temporary" repair was to literally string some fifty-pair IW along the roadway and lay it in the bushes. No temporary poles, no protection of any kind, not even the use of outdoor service cable. This lashup hack job sat around for nearly the past ten years. Within the last year, GTE decided to bury a permanent cable. Did it dig a nice neat little trench at the side of the narrow road? Of course not. It tore up a trench right down the middle of the road, buried the cable, and then did a wretchedly poor job of filling it in. Since I have to drive this road regularly, it is a constant reminder of GTE's wonderful way of tending to business. Isn't there a GTE in Florida? John Higdon | P. O.

I think a call to DEAN TECHNOLOGIES at 1-800-545-9754 will result in a smile on your face. (303-693-6189) Dean Technologies is a second source MITEL repair facility located in Englewood, Colorado. According to their 1992 price sheet, the cost to repair your Remote Call Status Display is but a paltry $69.00! They also SELL most parts for the SX-20 as well as the SX-10, SX-5, SX-50, SX100/200/200 digital, and SX2000 at reasonable prices. I'm an SX-2000 man myself and have no experience with the SX-20. I have a network of (currently) eight SX2000's, comprised of five "SG"s and three "S"s with six of those machines here in Houston. Two of the three-cabinet "SG"s stand side-by-side across the room from me right now. I began using Dean Technologies on the recommendation of a fellow classmate I met three years ago in Mitel school down in Boca Raton, FL (before they closed it up). I was getting frustrated by what I considered to be shoddy repairs of my E&M trunk cards, high repair costs, poor repair warranty and full charge for a repair when no trouble was found! When I'd send Supersets in for repairs, MITEL would fix 'em but send 'em back still dirty with frayed cords, etc. When I complained, I was told that "refurbishment costs extra." At Dean Technologies, instrument repair is not only less expensive, but INCLUDES refurbishment. Circuit boards come back within 10-14 CALENDAR days FIXED, upgraded to latest firmware revisions, and with a full two-year warranty on ALL repairs. They also do not charge for "no trouble found" repairs, just return shipping. I've been very pleased, and think you might be too. ... and just on the chance that someone from MITEL is reading this, let me say that I'm most pleased with every piece of my MITEL equipment. However, IMHO, their Ogdensburg repair facility could sure take some lessons from the folks at Dean Technologies. Bill Garfield | Standard Disclaimer Applies.

As a former student of Florida Tech I'll attempt to answer this one. Some background on the Florida Tech phone system ... FIT has all on campus phones, including student housing on a PBX. The number is 1-407-768-8000. When you dial it you will be greated with the message: "Thank you for calling the Florida Institute of Technology, if you are calling from a touch tone phone please enter the exchange you wish to dial, otherwise please wait for assistance." Students are not charged for local service which includes the Cocoa, Cocoa Beach, Eau Gallie, Melbourne and Sebastian exchanges. All extensions are four digits, and all housing are in the range 8200-8600. In the spring of 90, they began offering a package of call waiting, three way calling and call forward (on campus only.) There is also voice mail for each extension. Very primative, but workable. Long distance service is limited to FIT's outbound WATS. You cannot select your own LD carrier. The provided carrier pricing is fair at best. If I had returned for a second year I would have lived off campus, I couldn't stand the phone system. Simply put ... the phone system royally stinks IMHO. > HOW does CID work in this enviroment? As far as I know, Southern Bell does not offer CID in the Melbourne area yet.

After my home phone rings three (my choice) times with no answer, or when my home phone is in use, a call is transferred to my office phone. (I could have chosen to have forwarding only on one of Busy and No Answer.) Either I pick up there, or ASPEN voice mail takes the call (after one more ring). It's pretty much like having Call Answer or Message Center but without the stutter dial tone indicating a message. The down side is that I have to check my voice mail at work more often, but I could set it up to notify me of messages (though not on the phone that's forwarded, or Ms. ASPEN will spend a lot of time talking to herself). The quirkiest thing about it that I've found so far is what the caller hears, at least when the call is local (R=ring, .=silence): RRRRRR......RRRRRR......RRRRRR......RRR.........RRRRRR ^^^ office phone rings here ||| This half ring and long three-second pause which follows could throw a caller. I'll see what people say. It took several calls to New Jersey Bell to find someone who knew that FCF was available without Answer Call, but Denise in the business office there was the consummate knowledgable professional. Comments I got from Digest readers encouraged me to pursue the issue. The hook- up fee is waived during the Call Answer promo, so it's $0 to get started and $2/month for me to get all my messages in one place.

SprintLink is a router-based network supporting the TCP/IP protocol suite for data communications. SprintLink is part of the company's expanding service to the business, scientific and research communities. It complements Sprint's frame relay and SprintNet(R) (X.25) services for computer and local area network (LAN) interconnection. SprintLink also provides access to the Internet, a group of about 8,000 interconnected data networks in more than 80 countries serving government, academic and research organizations. "SprintLink demonstrates the benefits of technological collaboration between government and industry," said Chris Rooney, president, Government Systems Division. "The extension of this new service will generate commercial applications and will help American business and government be more productive and creative." SprintLink grew from Sprint's expertise in TCP/IP and international networking. In early 1991, Sprint began providing and managing a network to link the National Science Foundation's U.S. computer communications network (NSFnet) with the French scientific and research network, INRIA, at Sophia-Antipoles in southern France, and the Scandinavian scientific and research network, NORDUNet, in Stockholm. Sprint has since added to its NSFnet interconnections links to Japan and the United Kingdom. Additional connections are currently planned to South Africa and to numerous Latin American and Caribbean countries. In February, Sprint introduced SprintLink to government agencies. Since that introduction, SprintLink has attracted more than a half-dozen major customers. During the next year, Sprint plans to add gateways to Sprint's X.25 public data network, SprintNet, to allow SprintNet users to access SprintLink, both nationally and internationally. Sprint will also connect its frame relay service to SprintLink thus allowing Sprint's frame relay customers access to the global Internet and to enable management of routers connected to Sprint's frame relay in an integrated manner. Sprint plans to offer SprintLink on a dial-up basis. SprintLink is accessible via dedicated lines from all of the company's 270-plus domestic points-of-presence. Customers can access the service at speeds ranging from 9.6 kbps to T1 (1.5 mbps). Customers also can maximize use of a T1 line by combining multiple voice and data services, including SprintLink, on that line, a feature available only through Sprint. SprintLink is priced at a flat monthly rate according to port speed for each location. Sprint is a member of the board of directors of the Commercial Internet Exchange (CIX) Association, a cooperative effort among public data internetwork (PDI) service providers to promote the fair, open and competitive operations of IP-based networking. Other members include General Atomics, which operates CERFnet; Performance Systems International, Inc., which operates PSINet; and UUNET Technologies, Inc., which operates AlterNET. Sprint is a diversified international telecommunications company with $8.9 billion in annual revenues and the United States' only nationwide all-digital, fiber-optic network. Its divisions provide global long distance voice, data and video products and services, and local telephone services to more than 4 million subscriber lines in 17 states.

For enlightenment: I see faxes advertise that talk about "voice vs. fax" calls, and a lot of provision (jacks?) for answering machines. How do these things work? I presume the incoming fax is detected, after answering, by the funny beep beep tones from the orginating fax machine. But to then listen for a while and pass the call on to a conventional answering machine, you'd have to re-generate the ring voltage. Is this how these things (and the "voice/fax/modem" switches) work? If so, it would seem that if I disable the phone ring built into the fax machine and plugged my normal telephone into the answering machine jack I'd have exactly what I wanted. Or, do I misunderstand the whole thing? chris ------------------------------ From: kev@sol.acs.unt.edu (Kevin W.

A friend of mine is the proud owner of a brand new integrated fax + phone + answering machine made by Panasonic (I do not know the model). He has also other three phones connected in parallel to the same phone line. The Panasonic is set so that if no human answers the phone(s) after the first four rings, the machine picks up the call and after determining if te call is voice or fax it either switches the fax or the built in answering machine accordingly. Often when he is in the garden or in some other remote parts of the house, four rings are too much of a short time to pick up the phone before the fax/answering machine automatically answers. Since the maximum number of rings which may be set on the Panasonic (as with other similiar systems) before it answers the line automatically is four, we are wondering whether some simple device exists or can be built in order to increase this number of rings.

A LATA is a lot bigger than your neighborhood. It is usually much of your state. The problem with inter-LATA CLASS is that the IXC-LEC interface for SS7 is not yet deployed, and may not even be official. (People at Bell Labs, Bellcore, and/or the other IXCs can chime in on the truth of that statement) And the SS7 information must be carried by an IXC for interLATA calls, even if the LEC (or its parent company) is the same on both ends of the call. Remember that with few exceptions (like Northern NJ <-> NYC) only an IXC can carry inter-LATA traffic, *including SS7 signalling*.

And it has some problems, at least from my point of view. Here in NJ Bell land, you can presubscribe this feature or pay $.75 per usage. Well, my cable TV was out and I needed to call them for a status update. Their repair number (201-915) was busy, so I used this feature from my home phone (201- 451). Both of these prefixes are on the same switch, a 1AESS (primary ex- change 201-332). When I got the ringback and picked up the phone, I got a "per-chunk" (louder than the call waiting one) followed by "We are sorry. Your call cannot be completed because the number became busy again". I'd think that it would seize the destination number while attempting to notify me. I'm also interested in seeing if I got billed the per-use fee for this non-feature 8-).

GTE has had at least two CLASS features available for some time: distinctive ringing (ringmate) and busy number redial. I have had BNR for over a year. I believe it does BNR by terminator queueing. Of course, only numbers in my switch can be used. GTE has a target date of November 1992 for offering the rest of CLASS, except for CLID, Call Trace, and Call Return. Call Trace should be available later, after the public education program. I have been told by GTE that they are adding SS7 links by "market clusters" -- they group nearby switches into clusters and implement SS7 between them. Then they link the clusters to each other via SS7. I've also been told the target date for SS7 links to PacBell is late 1993. My switch is in the Laguna Beach/ Huntington Beach/Westminster "market group" and is scheduled to have SS7 links to the others by November 1, 1992.

It is possible that trenching in the middle of rural gravel roads is a standard practice.

Since the line goes across a state line and from Centel's territory into whoever has that part of Georgia (Southern Bell, I think), I doubt if it is any sort of a normal line. Perhaps some sort of an FX line but I think that those kind of things would run over regular lines and go through central offices. I like Pat's suggestion about them perhaps being a disguised ELF antenna. There is a large federal communications facility about six or so miles away from the end of the line in Georgia. I suspect though that it's some sort of private circuit between a plantation office and one of their outposts. ------------------------------ Date: Wed, 29 Jul 1992 21:29:00 +0100 From: rickie@trickie.uucp (Richard Nash) Subject: Re: Is Not 100% SS7 Needed For 1-800 and the Like?

The 1-800 service does not require 100% SS7. For this service, only a SS7 link from the switch that is required to translate the 800 number back into a regular phone number, to a database is required. This translation is performed at a switch that will record billing info. This link can be used to interconnect to other switches for other purposes also. Physically, the link from the switch connects to a messaging relay switch called a Signal Transfer Point (STP). The STP will decide where to route the message. Even though the switch your phone connects into may not have SS7, the 1-800 route will connect into a switch that can service these types of calls. They are called Service Switching Points (SSP).

This is > a little less traumatic on the metal contacts, and any residual debris > left behind won't be electrically conductive and threaten to cause > short-circuits in any electronics that might be nearby. I would suggest that you don't use a pencil eraser. As one my previous jobs, I worked as a technician on some 1 MW peak radar systems. The filament voltage for the final tube in this thing (no, it wasn't a magnetron) needed 1.5 V at 900 Amps. The connections consisted of a metal blocks with thick copper braids that were clamped directly to a similiar blocks on the tube in question. As can be imagined, there were over current, under current, overvoltage and under voltage sensors all around this thing so that any increase in resistance in the contacts would shut down the system. Therefore, us techs who worked on this thing were very interested in keeping the contact resistance down for as long as possible. As it happens, most pencil erasers have some sulfer in them; so, while one could use the eraser to get rid of the surface corrosion and temporarily make better contact, the sulfer traces left behind by a pencil eraser would react with water in the air, making sulfuric acid that would corrode the metal. A little extra fine emery clock/steel wool is therefore better than the pencil eraser; a dose of denatured alcohol afterwards can get rid of the particles. While we didn't use any at the time (this was a looong time ago), a little conductive grease to exclude air at the point of contact might be in order; this stuff can be found at any reasonable electronic parts store.

I had exactly the opposite experience. I called MCI and wanted to sign up for "Friends and Family", and "Reach Out World" (or whatever is the MCI eqivalent of it). The person I talked to got a list of my Friends and Family, and all other information and told me that I will be receiving a "Welcome to MCI" package within two weeks, and that the dial-1 carrier will be switched sometime around the same period of time. That was on June 5th -- about two months back. I am yet to receive the welcome kit, and ATT is still my dial-1 carrier.

You'll note there are various sub-directories in the archives covering dozens of topics. Almost every issue of TELECOM Digest is available in the first several sub-directories, broken down by year. Within each of those directories one will find the back issues in groups of fifty issues each. There are exceptions to this with the very, very old issues; and a few of the oldest issues are missing, but most that were missing have been found at one site or another and put in order here. All the areacode files have been updated in recent weeks by Carl Moore to reflect the several changes since these files were first installed back in 1989-1990. In addition, Carl has recently updated the 'history. of.area.splits' file. We have several glossary files including a new one uploaded to the archives just a couple weeks ago which was found at a naval FTP site. Among the various index files is one which is an accelerated index to subject and authors in Volumes 9-10-11 of TELECOM Digest, covering the years 1989, 1990 and 1991. This will be updated at the end of this year to include subjects and authors for 1992 in Volume 12. The way you use the accelerated index is by taking it back to your site and first uncompressing it. It is *very large* (as are many of the archives files as you will see), so it is recommended you have lots of spare room to store it. After it has been uncompressed (it is many thousands of lines in length), you then use grep to seek out phrases, author names, volume and issue numbers, etc. The file is in strict alphabetical order ignoring the 'Re:' which appears at the start of many messages. Where two or more articles are identical in title, then the sort continues by the author's first name and last name, i.e. John Higdon would come before Robert Adams. Due to some irregularities and inconsistencies in the use of upper/lower case and the occassional typographical error it is suggested you use the most liberal instructions you can with grep; for example ignoring case, using wildcards when possible, etc. Please note that being too liberal in your search criteria will result in a huge number of things you do *not* wish to see ... and being too specific in your search may cause you to miss something. Experiment around for the best results. Read the several lines at the top of this file which provide additional help in locating what you want. The 'telecom-recent' file contains the most recent batch of fifty issues of the Digest. This file is flushed on the fiftieth and hundredth issues, with x01 - x50 (or x51 - x00) moved to permanent storage in the sub-directories at the top of the list as soon as I can after distribution. You can pick up recent missing issues from this file. How to get there from here: Use anonymous FTP: ftp lcs.mit.edu Login anonymous, and use your name@site as password. When logged in, 'cd telecom-archives'. On your first visit, you may wish to simply pull the various index files and take them back to your site for review. Anonymous FTP is limited of course to Internet sites, and that is a pity since so many readers of the Digest and comp.dcom.telecom are at UUCP sites or entirely different networks. Those folks will need to use an email <==> ftp server ... and although we've had these around from time to time, I don't know the address of any at present. == Can anyone provide us with a good reliable email <==> ftp link? == If so, you'd be doing a big favor for all the Compuserve, MCI/ATT Mail, and UUCP sites reading the Digest ... please write me with details.

and others. You can capture those yourself during your visit to the Archives. I want to especially point out that if you want a complete and up to date area code list, the one in the archives was updated by Carl Moore just days ago and anticipates changes being made in the next few months. And of course Dave Leibold's hard work with the country code tables is to be commended. (Carl also worked on this.) The archives changes daily as each new issue of the Digest is filed away, and new files of all kinds arrive almost weekly, so keep up to date by reviewing the main directory each time you visit.

There are approximately 48,000 telephone lines connected in 17 franchise areas. Several other cable television operators plan to introduce telephony services to subscribers by the end of the year. ------------------------------ From: kenny@osf.org (Kenneth Crudup) Subject: NET and a Noise-Free Line: Impossible? Organization: Open Software Foundation Date: Fri, 31 Jul 1992 18:48:18 GMT HELP! When I moved into my apartment two years ago, I had New England Tel (NYNEX) put in three additional lines (I'm getting like Higdon! :-). One of those was my outgoing-only terminal modem line. When it first came in, it was noise-free, or at least clean enough that I didn't notice. Now, I can't even call Cambridge 621- from Boston 983- without getting random modem noise. It shows up as random characters (not all just "{"'s and "~"'s, either) every minute or so, in groups of one to three, but sometimes it will go as long as ten minutes without a noise hit. Sometimes it just shows up as recieve noise (doesn't get to the other system), sometimes it gets to the other modem as well. Oh goody, I get to call 555-1611. So I did. First time, I got the automated system. Other than hanging up the connection on it at the time (I guess as a line check), I didn't even get so much as a callback on the daytime number I left. Tried it again, got a human, same result. Third time, ditto. Fourth time, they tell me they've got a log entry where some tech went out there and put his noise meter on the NI and found "nothing". I guess for voice, you won't. I said, have him come out again, and I'll show you the problem. I moved the computer down to the second floor, for easier reach, and ran a 25-ft RJ11 extension out the kitchen door to the NI, (outside, unlocked, on the ground level!) to eliminate the house wiring as a source of the problem. Thankfully, the problem showed while the tech was there. I used a different modem, and a different terminal, to prove it wasn't the equipment. He ran his noise meter again, and told me that there was "nothing he could do". He said I could go to business tariff, and I told him that all that means is that they charge me more, but I won't get a new line pair. ("Oh yeah, I guess you're right".) He told me then about a "special line" I could order for "computer stuff", that I found out was a leased line. Thanks. (I did wonder that if I brought that line up to business tariff, that they would be *forced* to make that line clean. Since it's deductible, I'd go with it.) I wanted him to run a new pair for me. He said he couldn't, but he said that he could see my problem. I believe he was just trying to get out of it, and I asked for the name of his supervisor/group leader. He "hasn't been in". What should I say/do next? I just want a noise-free (at least regular clean) line. Some more background info: I was on Martha's Vineyard a month ago, used the same line to get in, left it a while, no noise. My officemate lives out in the sticks, no noise. Noone else complains, either. When I called repair service, I tried to sound telecom literate (using terms I culled from c.d.t) so they wouldn't ask me the dumb question set, and take me seriously. I asked if I had a SLC (slick) on the line(s), no one could tell me. When I moved the modem over to one of the other new lines, same problem. I haven't had the modem on the home number long enough to see if it shows up on that one. Thanks in advance. Kenneth R. Crudup, Contractor, OSF DCE QA OSF, 11 Cambridge Center, Cambridge, MA 02142 +1 617 621 7306 kenny@osf.osf.org OSF has nothing to do with this post. [Moderator's Note: When you mentioned you had the same problem with the modem on one of the other lines, it occurred to me that perhaps your modem is at fault. They do go out of calibration, you know. Try the modem on different lines, then try a different modem on the original line and let us know what happens.

I went into a restaurant in Bethesda, MD and discovered a different pay telephone. It consisted of a desk-style Touch-Tone* telephone with two special additions; one is a green "TALK" button (more on this feature later), and the other is a coin slot. The phone claims to accept dimes and nickels for calls. Here's the kicker: the sign on the front: 25c Call: Local Calls 25c / Long Distance 25c a minute Insert 25c; dial number; press TALK button to talk. It will dial 911 and 1-800 numbers without coin (it claims; I had to go to work and could not do a full test)*. I did one test they would not have liked. I put in a quarter and dialed the local number for time. I was connected and did hear the annoucement. I hung up and my 25c came back, so it is acceptable for calling a number that is busy or does not answer*. They also provide CANADA and CARRIBBEAN at $1 a minute; with Canadian rates reaching around 30c a minute that's a little steep*; but let's look at the U.S. rate structure. The current dial direct rate for AT&T and such is running around 11 to 18c for calls in the USA*; however, based upon the surcharge of 75-80c for a credit card call, this type of phone would be {cheaper}* for calls of {11 minutes}* or less: Call Length 3 Min 4 Min 5 Min 6 Min 7 Min 11 Min 12 Min Call Rate 54 72 90 118 136 198 216 Surcharge 75 75 75 75 75 75 75 Rate 129 151 165 187 214 273 292 25c/Min 75 100 125 150 175 275 300 These rates do not count taxes imposed on calling card calls, and discounts available, but this type of phone is {cheaper} for most people's long distance calls when you have to pay a calling-card surcharge on the call.* What surprised me was the amount of time you have to be on the phone {before} this phone is more expensive! 12 Minutes! *Your mileage may vary.

There is some discussion on one of the Fidonet conferences regarding numbering plan matters. Bellcore assigns the area codes in the North American Numbering Plan, but the discussions I've run across mention that Bellcore also assigns the prefixes within each area code. I know that Bellcore maintains V&H and other lists of prefixes, but assumed that the predominant telcos in each area would be responsible for setting up prefixes (apart from some common, special-use numbers like 555 directory assistance, or 976 premium/announcement, or 958 and 959 for testing), and that Bellcore would compile the assignments from each region for the various tapes and lists, etc. In most cases, there is a predominant telco for each area code, such as a BOC. However, there are special cases like 813 in Florida where the region is shared by more than one company (GTE, Centel, etc) which could result in some interesting battles over prefix assignment.

I gather that he works for Illinois Bell, but I'm not sure exactly what he does there. (begin forwarded message) IBEW Local 165, the union that represents technical craftspeople in the Illinois Bell region has notified it's members that IBT will be offering it's SIPP (voluntary early retirement program) to "Network" personal around the September 1. This is only the second time Network has ever been offered SIPP and even this offering is gong to be limited. Following that process, 20 to 100 first level managers are going to be "offered the opportunity to take their tools back." i.e volunteer to be demoted. Local 165 in a move that they knew was a waste of time, asked that those union members already part of the Upgrade and Transfer Program (at IBT, and no doubt other companies, you can nominate yourself for a lateral or upgrade transfer -- i.e. a promotion -- this has proved successful for moving through the crafts, but virtually no one gets promoted to management via this system) be the first ones offered the positions that would be vacated. Illinois Bell promptly froze the Upgrade and Transfer Program making the point moot. At this point, it is not clear whether the number of managers to be offered their tools will coincide with the number of craftspeople taking SIPP. It is also unclear, but suspected, that only those craftspeople who have a qualified manager to replace them will be granted the SIPP. On a personal note; No not me, while I've got enough years (23), I'm still too young, 41 (well, I think that's young anyway!) for an early retirement offer. However, my supervisor (who also happens to be my oldest and best friend in the company) has only been management for two+ years and our department ran unsupervised for 12 years, so he's not a real pleasant fellow to be around right now.

I've got some flavor of Panasonic two-line phone in the office. There are two of these phones; one up front, one in a back room. The problem is that whenever I don't think that these phones are hooked up properly. I can make a call out on one line, hang up, get a dial tone and hang up again. Then have the phone ring on the line that I was just on and still be connected to the call I made previously. This is after I flash the hook and get a dial tone. I always thought that a dial tone meeant that ypu had a clear line. Why would the phone ring again and still be connected to the last call? It looks as though the phone company instwlled two lines into the phone through one physical line (RJ-11?) It hooks into a slot labled line one and two. I don't know enough about phones to figure this one out. It does bug me though. Thanks.

I would like phone calls into this system to be local calls for as wide an area as possible (the area in question, if it matters, is the San Francisco Bay Area). Is there some technique to determine the optimal location for this system so as to provide local access to the greatest number of callers? Perhaps Pac Bell can determine this for me? Additionally, can someone explain to me what distinguishes local calls from toll calls? Are all calls within a LATA local? Does physical proximity have anything to do with determining whether a call is local (i.e. is it always the case that calling a couple of blocks away will be a local call)? Assuming physical proximity had something to do with it, I've always fancied setting up a dial-up system which chained together a bunch of local calls, but for which the end-to-end call would have been toll.

Features available within a single switch are hardly very impressive. And distinctive ringing is actually a scheme to sell the customer both (or mulitple) "sides" of a single "party" line. It has little to do with CLASS although it is usually bundled in with CLASS offerings. Priority ringing (as offered by Pac*Bell) is a CLASS feature, since it requires SS7 signaling between offices to pass the caller's number for checking against the callee's list. But here is a bit of provinciality: in the Bay Area, Pac*Bell SS7 connectivity is virtually 100% (excluding only a very few non-SS7-capable prefixes). GTE has 0% SS7 connectivity here. It does not even have it internally. Is it too much to expect that the largest LEC in the country, doing business in the fourth largest SMSA might join the party and provide a level of service that remotely compares with the other major LEC in the area? Apparently it is if it is GTE. > GTE has a target date of November 1992 for offering the rest of CLASS, > except for CLID, Call Trace, and Call Return.

Actually, there are two versions of this feature, usually called "originating scanning" and "terminating scanning". The terminating version operates by having the destination CO maintain a queue of numbers to notify when a line becomes available. Those queued are notified in order, with a complex scheme of requeuing for cases where the caller is busy or doesn't answer, or the timers in the 2 switches are not set equally. The originating version is simpler, in that everything is run by the caller's CO. It periodically uses SS7 to query the busy/idle status of the desired line, and notifies callers when idle is seen. Since many switches could be doing this, the "queue" doesn't exist; it's just a random function, like many other parts of the telephone network. Which version is used depends on the availability of terminating scanning in the terminating switch, and the purchase by the TELCo of that option. If the initial request from the calling CO doesn't indicate that terminating scanning is available, the originating switch uses originating scanning. There are advantages to each form of scanning: Originating is "fairer" in one sense to mass calling numbers, because everyone gets a equal shot at the next line -- not just the one person at the top of the queue (or in the same CO as the called line). But to the individual, it's not as "fair", because they aren't assured a callback in the order queued. BUT IN NEITHER VERSION is the newly-idled line "held" for just one caller. Any regular incoming call to that line will connect if the line is idle. Nor is the line prevented from originating a call while someone is being "rung back". There are issues of fairness, reliability, call capacity, memory and feature interaction that dictate the current implementations. The feature was designed to handle idle-line notification for moderate usage lines -- in many cases, mass calling numbers are blocked from being valid numbers for "repeat dialing", because it's viewed as an inefficient mechanism for such usage. Maybe someone will come up with a better method for the mass calling case someday; if so, it probably won't rely on "ring back". ------------------------------ From: n1gak@netcom.com (Scott Statton) Subject: Re: Pac*Bell CLASS Features Date: Fri, 31 Jul 92 17:05:57 GMT Organization: Netcom - Online Communication Services (408 241-9760 guest) In article terry@spcvxb.spc.edu (Terry Kennedy) writes: In a previous edition of the digest, Terry Kennedy explains how he tried to use Camp-on to call the busy CATV service number ... > and picked up the phone, I got a "per-chunk" (louder > than the call waiting one) followed by "We are > sorry.

Let's assume that Terry's suggestion is taken, and the destination number is "seized". If the customer picks up the phone, " I'm sorry, you cannot use this telephone, because someone is trying to call you. Please hang up and allow their call to return to you." Or what if you initiate the feature and wander away. How long should (how long does it now?) wait for you to answer the stutter-ring, and re-initiate the call? Someone suggested that Busy-redials should be queued in the terminating office, and answered in order. That may well be how they happen, but the over-riding concern is the customer has the ultimate control over the terminating number. Another story about Busy-Redial: A friend who works for The Company recently ordered this feature. He intiated a busy-redial on a local Bulletin Board system that is almost always busy. Now this particular system has a ten line hunt group, and he (as all callers do) dialed the lead number, and initiated the busy-redial. Only when THAT PARTICULAR term became available did he get the recall-ring. Of course, with SEVERAL DOZEN (!!) busy-attempts per minute, he didn't have a chance, in the time it took him to pick up his phone, someone else got the port. Does anyone have the feature-interaction cross-ref for Busy-Redial and hunting? I can obviously see how they implemented it (415-961 a 1A ESS) on a per-termination basis. In other offices, can it be implemented on a per-hunt-group basis?

We, also have the modem pool and the various flavors of TAU or telephone access units. O.S.U. hired some Ericsson personnel to stay here, permanently after the cutover, and maintain the system as well as train new staff. We have had some problems with the modem pool, but Ericsson has always tried very hard to make it work. After much hew and cry from residential students and staff, the Telephone Services Department has been instructed to make analog lines available, no questions asked, for special modems, fax machines, etc. I understand that analog lines pose a difficulty for the MD110 switches because they use more resources in the switch node than standard digital lines. The discussion of the MD110 installation at Boise State brings a few ideas to mind. Digital phone systems are here to stay. For the foreseeable future, most of the telephone equipment freely available will be analog. The designers of digital PBX's need to better address this problem. There isn't any really good reason why inexpensive interfaces can't be designed which bridge the analog and digital domains at the terminal level. If this were possible, then all of the line cards in the switch could be digital. While not all the features of the PBX could be preserved on the analog side of the interface, the most basic ones such as ringing, dialing, and hook status would not really require much engineering to implement. Administratively, there needs to be a workaround for situations which arise that don't lend themselves to the standard interface. One shouldn't have to raise forty kinds of Hell to be able to use an answering machine, conference phone, or other device which wasn't thought of in the original master plan. If reasonably-priced analog/digital interfaces which worked at the terminal level were readily available for anybody who wanted to buy or rent them, much bad blood between the telephone department and the rest of the university would disappear.

Whoa, who said anything about limiting the scope to just payphones? Most of the times I use my calling card number, it is *not* from a payphone, it is from a "regular" phone in a hotel room, rental property, or home of a friend or relative. I believe this is what the first poster meant by "most telephones in the country". Upgrading a couple hundred million personal telephones to incorporate a card- reader seems rather unlikely. Remember, although stored-value cards have their uses, they are still essentially glorified payphone tokens, so their range of capabilities is very narrow. Calling card accounts are much more general-purpose because they can be used from almost any phone in the country (and even some outside).

In fact, they were getting a bit worried about pestering the same people all over again in an effort to get enough people signed up in the test area. They're now at the stage of trying to sign up Joe and Mary Sixpack for some real world testing, although they are currently stuck waiting for another shipment of prototypes to arrive before they can get more in circulation. I told Mr. Kim about TELECOM Digest the other day on the phone, and I think he was a little apprehensive about it until I pointed out that the Digest is read by everybody including Ameritech, and the information in the last posting was nothing that hadn't been in the papers a couple of months ago. I passed along a copy of my original posting, and also a listing of their local Ameritech <-> Internet connection that I obtained from local maps, so hopefully they'll be contacting TELECOM Digest themselves in the near future!

Something to do with: communities that have no cable, are hard to reach, small, the government is selling licenses like with cellular. What your friend is probably referring to is more accurately known as MMDS or "multi-point microwave distribution system". It is a controlled direction transmitter in the Ghz range (I think around one or two, but I will check and advise) which typically now carries 20-30 TV channels. It is received by a small, approximatly one foot diameter, parabolic antenna which is often mounted on an existing TV antenna mast. License have indeed been under distribution by the FCC for several years. A number of fraud complaints have been lodged by promoters marginal to ridiculous claims of high profits to be made by this service. One such service calling themselves "Choice TV" recently went into business in Fresno, CA. They offer 28 channels and one "free" pay service for about $29/month and have additional pays and pay- per-view movies available for extra charge. I believe they actually transmit about 20 channels, received from satellite, and have a frequency convertor that takes the off-air signals off a regular antenna (we have only UHF stations in the valley) and converts them into a "seamless" channel lineup. The service avoids the cost of stringing cables to homes and also avoids payment of franchise fees to the cities and counties that hard line cable operators must pay. Because of the high frequency involved their transmission is essentially line of sight. If you can't "see" their transmitter, you can't get the service. They will be subject to the usual microwave problems of rain fade and inversion layer problems. While the many channel services are relatively new, there have been one to five channel services operating for some time, at least since the early 80's. Anchorage had a pay service there on one for many years. And now a quick recap of similar / confusing / related services: home dish satellite -- receiving antenna about 5-10 feet diameter, receives C band (3.7-4.2 Ghz) Tx, same satellites the cable operators use, scrambled with marginally secure VideoCipher technology, needs "big" dish, little rain fade, subject to telephone microwave interference from terrestrial point-to-point service which is in the same band, needs good view to the south of orbital arc. DBS (Direct Broadcast Satellite) -- relatively new service in Ku band (roughly 12 Ghz), dish two to four foot diameter-much smaller, less obtrusive, subject to rain fade (though this is less of an issue ith newer high power Ku band satellites), various TV service packages are marketed by various companies; most in "test" stage. This is where things like "Sky Channel" are slated to be. Low power TV stations are either stand alone broadcasters or (like most) repeaters of nearby broadcast stations. They may have as little as 100 watts and can go as high as 1Kw, but I'm not sure of the upper power limit. They often will Tx to small valleys, pockets that have no cable and can't get off-air because of the terrain. Some of these licenses have been auctioned or lotteried by FCC in the last few years and have had the same complaints as MMDS on over zealous marketing. If you have other questions in this area or I have failed to clarify something, you can address questions directly to me as above and I will summarize same.

Mendelson is located in Dayton, Ohio and advertises in Computer Shopper and assorted hobbyist magazines. As far as I know, the manufacturer is still around because I still see "Complete Xxxx" products for sale. The CAM is a PC-ISA board with CODEC and DTMF decode and generate capabilities. Up to seven CAM cards may be installed in a machine. A 286+ machine is recommended for multicard use. My CAM card is in an old AT&T 6300 that I keep around the house for "in case of emergency, break glass" conditions if my serious machine fails. CAM is pretty neat, offering most features of what commercial voice mail systems. CAM also runs in the background with DOS. I tried it in my '386 with DOS 5 and windows running. CAM took and distributed messages with minimum impact on foreground applications. CAM supports multiple mailboxes and can do call transfer by hook flashing and DTMFing. You can set it up as an el-cheapo automated attendant. CAM also supports message forwarding. I've got it set up to beep my pocket pager when somebody leaves a message. The CAM software is pretty good and supports enough flexibility that you probably can do whatever you want. They don't have a generalized scripting system like the covox developers' kit or AT&T voice power. CAM is probably about as flexible as the Genesis CINDI that we have at the office. If you don't care about using an ISA PC, keep an eye on the for sale group. The AT&T UnixPC outfitted with a voice power board is pretty affordable system. (I've got that too). I don't have the AT&T answering machine software, so I can't comment on that. The basic voice power software does give you the ability to write routines that interface nicely with shell programming. We set up a job info bank at work with a voice power board and UnixPC because at the time, the Genesis software wasn't really configurable enough to meet our desires.

OFFICIAL? -- hey, not from me. But in the: "North American Numbering Plan Administrator's Proposal On The Future of Numbering In World Zone 1", Jan. 6, 1992, published as an Information Letter from Bellcore, there is a statement (from memory) to the effect that -- The primary LEC in each NPA is responsible for assigning Office Codes. That should not imply there is no discussion/agreement with the other LECs or Bellcore in the assignment process; just that the primary LEC has "official" responsibility. By the way, the discussion you mention will be somewhat confused if the term "prefix" is used for office codes (or one of the other popular terms). I believe "prefix" is understood to be the digits in front of the actual "number", such as 1+, 0+, 10XXX, *70, etc. Bellcore certainly has recommended "prefix" assignments -- I'm not sure anyone has undisputed ownership of such assignments. The current (and increasing) mess of CLASS(sm) feature code usage and "local" service marks for them would suggest some TELCo's view "prefix" assignment as a "local matter". Al Varney - just MY opinion. ------------------------------ End of TELECOM Digest V12 #600 ******************************
