Patrick Townson ------------------------------ Date: Thu, 31 May 90 10:47:32 P From: Hank Nussbacher Subject: TSL - Trans-Sovietic Line Bell Colorado has signed an agreement with the Ministry of Telecommunications in the USSR to build a $500 million dollar trans Siberian fiber optic line. The line will be 13,000km long and will support 565Mb between Japan and the USSR. The line is expected to become operational in 1994. A special company has been set up called Soviet Line Development Company. The problem is that most of the equipment is Cocom proscribed which Bell Colorado is trying to work around. Denmark, Britian, Italy, West Germany, Japan, Australia and the USA have all backed this project. There are expected to be three "branches" off of the Trans-Siberian cable: 1) To Copenhagen via the Baltic Sea 2) To Czechoslovakia and central Europe 3) To Italy via the Black Sea The 565Mb is the first stage with stage two increasing the capacity to 2.5Gb and stage 3 to 10Gb. ITU documents indicate that this will be the longest fiber optic cable in the world. Most of the cable will be laid along the Trans-Siberian rail. West Germany has also informed the ITU that it too is building a fiber link to Moscow - Frankfort-Berlin-Warsaw-Moscow. There is a possibility that it will connest to TSL with a spur off to Prague. The German cable will cost $60 million and is called Centrale Strecke. All this is to be a great leap forward for Russia. Today, the only fiber link they have is between Leningrad and Minsk running in single-mode at 140Mb (most telecommunications fiber today is multimode and is 1.7Gb). That link is only 100km long.

The Secret Service said the hackers who were the target of the probe are individuals who had gained unauthorized access to company computer systems -- including one at AT&T -- or had stolen and distributed software programs that belonged to major corporations. Kapor said he thinks the government probe has been misdirected and damaging to technological innovation and to dissemination of information. Gary J. Jenkins, assistant director of the Secret Service, said, "We will continue to investigate aggressively those crimes which threaten to disrupt our nation's business and government services." Maybe if Mr. Kapor had his Lotus 1-2-3 ripped off good he might change his tune. Anyone know other projects of his we might steal and start handing out freely around the net? After all, we wouldn't want to 'damage technological innovation or dissemination of information' now would we? Please keep his attitude on this serious problem in mind the next time you use or consider purchasing his software.

Two of the lines will only be answered by machine. The third is her personal line. The lines will have different answering messages. Are there any angles here with respect to lines that are answered only by machine? Can anyone suggest some good (cheap) hardware that would help to satisfy these requirements? I suppose an answering service is an option, but I expect it would be more expensive and less efficient than a machine. Does Bell offer machine-answered lines that are cheaper and do not require extra circuits to the house (i.e., you call up and retrieve messages with tone codes)? What are the appropriate rules with regard to residence vs. commercial lines? One of the lines is for a non-profit charitable organization and the other for a very small consulting business.

Texas Air operates Eastern, Continental, and a few small regional carriers. Their CRS is named System One. TWA still belongs to Carl Icahn, and TWA's CRS, which is indeed jointly owned with Northwest, is called PARS. It is unlikely that Texas Air could buy TWA even if they wanted to, they're in hock up to their eyebrows. On the other hand, AMR, the parent company of American Airlines, owns a CRS called Sabre, which is used by a lot more travel agents than System One or PARS is. UAL, parent of United Airlines jointly owns a CRS called Apollo. AMR is somewhat larger than Texas Air in assets, sales, and number of employees. UAL is larger in sales, about the same in assets and employees. It's hard to believe that Texas Air has a larger telecom budget than either UAL or AMR does. I suspect that since there is no standard way to measure the size of an organization's telecom budget, and since most organizations are under no obligation to tell any outsider what their telecom budgets are, the list that started this discussion in the first place has to be considered no more than an educated guess.

PT] Date: Mon, 8 Sep 86 16:03:35 PDT From: Dave Taylor Subject: Interesting Phone Calls AN UNUSUAL TELEPHONE SERVICE CALL This story was related by Pat Routledge of Winnipeg, Manitoba about an unusual telephone service call he handled while living in England. It is common practice in England to signal a telephone subscriber by signaling with 90 volts across one side of the two wire circuit and ground (earth in England). When the subscriber answers the phone, it switches to the two wire circuit for the conversation. This method allows two parties on the same line to be signalled without disturbing each other. This particular subscriber, an elderly lady with several pets called to say that her telephone failed to ring when her friends called and that on the few occasions when it did manage to ring her dog always barked first. Torn between curiosity to see this psychic dog and a realization that standard service techniques might not suffice in this case, Pat proceeded to the scene. Climbing a nearby telephone pole and hooking in his test set, he dialed the subscriber's house. The phone didn't ring. He tried again. The dog barked loudly, followed by a ringing telephone. Climbing down from the pole, Pat found: a. Dog was tied to the telephone system's ground post via an iron chain and collar b. Dog was receiving 90 volts of signalling current c. After several jolts, the dog was urinating on ground and barking d. Wet ground now conducted and phone rang. Which goes to prove that some grounding problems can be passed on. This anecdote excerpted from Syn-Aud-Con Newsletter, Vol 4, No 3, April 1977. [Moderator's Note: This time at least, I caught the 'Winnepeg, Ontario error' and changed it to Manitoba.

Anyone who considers Bermuda and the Bahamas not to be parts of North America is welcome to specify them, and if Belize is in the British Commonwealth, anyone who deems it in North America is equally welcome to make a specific exception for it.

Actually, dialing 200-555-1212 (or I'm sure any combination after the 555 will work) without a 1 before, will result in a recording reading back the phone number of the line you are calling from.

About 3 years ago our PUC ruled that then Pacific NorthWest Bell couldn't charge extra for touch tone service. For some reason Telephone Utilities still charged, I think, $0.55 per month. I, for one, was glad to get a retroactive credit for TouchTone service which extended back for a few months (4?--too bad it wasn't for all the touch tone service I ever paid for!). The glee I experienced was not one of "getting a premium feature for free" but freedom from the tyranny of being charged for something which wasn't eligible for real competition and obviously cost very little to provide. wallyk@tekfdi.fdi.tek.com (Wally Kramer) 503 627 2363 Contractor from Step Technology, Inc. 503 244 1239 ------------------------------ Reply-To: eli@pws.bull.com Subject: Re: ATT Special Promotion Date: Wed, 30 May 90 14:09:21 -0400 From: Steve Elias Our Moderator wrote: >AT&T is doing this as a special promotion to start off the three day >holiday weekend of reduced calling rates. >Obviously, you know how to route your long distance traffic tonight. >For more specifics and verification, call AT&T Customer Service at >1-800-222-0300.

If they really used the two pairs available in standard quad, as you suggest, then you will probably experience crosstalk, if there's any significant cable run. It isn't caused by sharing a duplex jack, but by the cable. For two-line service, they should use a cable with two (or more) twisted pairs. If they did, they would probably have connected one line to the blue-white pair and the other to the orange-white pair. If they did that, you shouldn't experience crosstalk, regardless of the connectors used. Dave Levenson Voice: 201 647 0900 Fax: 201 647 6857 Westmark, Inc.

There is a certain amount of dejavu here: Quad wire in phone installations causes crosstalk. The jacks that were installed will not be the cause of the crosstalk. So you can't blame the Mrs. for this one. Crummy wire could be a cause of crosstalk. You say that you have Red, Green and Black, Yellow wire. This stuff is called quad wire. It is not twisted pair wire. If you use quad wire you will get crosstalk between the two pairs. The right wire to use is "Twisted pair". This stuff has the following color code: White/Blue, Blue/White. White/Orange, Orange/White. White/Green, Green/White. As a general rule, the minimum number of pairs in twisted pair cable is three. Yes there is two pair around, it is rare but I saw some yesterday at Pacific Palisades - Surf was lousy though. The jacks are not the source of the crosstalk. I do this sort of thing all the time. In about an hour I am going to an establishment that has telephone and Appletalk sharing the same cable and coming out to duplex jacks. It works because it is twisted pair. So, if you have twisted pair, no worries. If you have quad - yuck. But the quad may work.

I'm getting the impression that Mr. Cook and those who are setting up the subsidized TDD service are of the conviction that Deaf = Poor. Just so we don't misunderstand each other, years ago I worked with the deaf in some of the poorest "hollers" of North Carolina. That was POVERTY. But just as in the community at large, so was there a spectrum of accomplishment among the deaf community. With that exposure, I have never had the impression that our deaf citizens are somehow unable to provide for themselves. Indeed, the non-hearing persons I number among my acquaintences are somewhat better off financially than I am. As far as isolation goes, a person who is deaf can adjust his own isolation. While there may be some who are content to sit back with self-commiseration, there are many others, who like those in North Carolina, will not let ANYTHING stand in their path toward achievement. BTW, what's the matter with some type of batched e-mail for the deaf? What about devices (like this computer?) that allow the user to compose and edit a message OFF LINE and then transmit it at high speed to a destination? Why does TDD communication all have to be on line, in real time? Hell, if I wrote and received my daily e-mail interactively on line at even local rates, the bill would be staggering.

Well, by that reasoning I should pay less to use a 300 baud modem than a 2400 baud one, or heaven forbid, a 19,200 baud one (ie: Telebit). Of course, that is not the case. Also of course, no one FORCES a deaf person to use a TDD to communicate. They can purchase a personal computer with a higher speed modem, compose their text offline if they wish, and transmit to other similarly equipped people. If the additional bandwidth is an issue, this is something these people should explore. Note that I can easily read at 2400 baud; that is not difficult, I do it every evening when logging in and reading the news from home. Thus, I can effectively make use of 2400 baud transmission in >real time<. I am willing to bet that most deaf people can make use of at least 1200 baud if not 2400 or more, should they be motivated to do so. The question becomes: Should a public utility be able to subsidise the use of a service by a disadvantaged (insert favorite of handicapped, minority, etc) group through the rates of those who are not as disadvantaged? That I don't have a good answer for. However, the issue is not bandwidth, nor is it the information able to be transmitted per unit of time. It could be a matter of perceived public service, or any one of a number of other factors.

Sure, it's EASY to use faster modems. The problem is, you have to communicate with all of the other TDDs that are out there. For the past few years they have tried to improve on this by adding 300 bps ASCII modems to TDDs. Of course, for keyboad-to-keyboard chatting, this may be academic, as most folks don't type much faster than 45 baud (60 WPM) anyway. ASCII has the advantage though of allowing full duplex. > Is anybody working on this, from the standards side, or the technology > side? EIA was working on it, but they gave up. They found that Crown and Ultratech are the only manufacturers, and they have been building their stuff for years with no standards at all, other than nominal frequencies (1.4 KHz Mark, 1.8 KHz Space) ... no tolerances for the receiving or transmitting ends. Last year I installed a 2400 bps modem in a new PC clone that a hearing impaired friend bought. Up until then she had been using 45 baud baudot, and ocasionally half-duplex 300 baud from her TDD to my computer. What a revealation for her when we communicated with split screen, full duplex, and 2400 bps for the first time! Instead of manually switching from receive to transmit on the TDD, she could now see typed text coming from me on the top of her screen, and she could type her responses at the bottom. Pretty soon we were both typing at full speed simultaneously, and for the first time she experienced something like a NORMAL conversation with a hearing person!

I just bought a 2400bps modem off the shelf of the local electronics store for $99. They can make modems cheap through mass-production, using standard modem chipsets. If 45bps BAUDOT were added to the modem chipset, then it may add maybe $20 to the cost of the modem. So then it's $120 instead of $99; still no big deal. Think of what things would be like with dual-mode modems. Service providers could use dual-mode modems to accept calls from regular modems or TDDs. BBSs, Telenet, Tymnet, public-access Unix systems, you name it. That way, every deaf person could read the Telecom Digest, and all the rest that the online world offers. Next, deaf people could start upgrading from regular TDDs to dual-mode modems. The modem would be the only thing you'd have to spend money on, because there are more than enough old glass TTYs that people are trying to get rid of. With the dual-mode modem, you could have higher-speed access to online services, and still communicate with all of the older TDDs. Even on interactive conversations between two TDDs, you could now have a faster conversation than before. I would make the modem so that it would have a phone jack and an RS232 jack. The RS232 side would always use ASCII, at a configurable baud rate (1200 to 9600, for example). You'd hook this up to an old VT100 or Televideo 920, if cost is an issue, or to a personal computer or 3B2 or whatever. The phone side would talk ASCII or BAUDOT, depending on what was on the other end. If it was a BAUDOT connection, the modem would automatically translate speeds and character sets. This couldn't be that hard, so why doesn't it happen? Is it simply the lack of a large, money-laden potential customer-base that keeps modem chip manufacturers from putting these features in? Maybe if we could convince other big modem users like Tymnet to want them, that would start the ball rolling to mass produce them. Just some food for thought.

The logical thing to do would be to use standard 300 baud ASCII-type modems. (Most humans can't type 300 baud anyway). They're readily available, and very cheap. But the problem is that the existing TDD's are the existing TDD's, and no one wants to be the first on the block to get the new, non-backwards comptable, technology. Would you buy a new phone that offered CD quality sound (suppose!), or, even, Star-Trek like universal language translation, if it meant that the only people you could call were people like yourself who had invested in the new technology? And that you could no longer call your neighbor and ask for a cup of sugar? I wouldn't. Or, at least, I'd buy both, but if financial constraints forced a decision, I'd stick with what I had.

My understanding is the discounts started years ago as part of AT&T's nice guy image. The primary reasoning behind them is the relative length of the calls. It takes a lot longer to type out a sentance than it does to speak it. Also having to type out things hearing people automatically pick up would add a tremendous amount of time to the length of a call. For example, when I call my mom, I might say "HI Mom ! What's going on?" A TDD user would have to type out "Hi Mom ! It's Bob. What's going on?" My mom would know it's me, but a deaf mom would not have any idea who it is without the extra words. I do not know if technology has increased the speed of TDD conversations since the last time I used it but on that occasion, it took me approx ten minutes to ask a deaf employee of ours where the storeroom keys where! If TDD conversations can now be conducted at the same speed as spoken ones, then AT&T has a reason for dropping the discounts. However, I do not think anyone ( other than maybe a professional transcriber ) can type as fast as you can talk. As someone who has used TDD before ( granted it was five years ago ), I think AT&T should continue the discounts. I also think the FCC should require all LD companies to offer them.

But one you may consider is the Viking Electronics "Loud Ringer/Auxiliary Paging Amplifier". From the blurb: "The PA-2A provides both loud ringing and auxiliary paging for electronic keys systems, 1A2 systems, and "KSU-less phones. It will generate an adjustable loud warble from up to six incoming C.O. lines or from a dry contact closure (TIE 612, Comdial Executech). Night bell transfer capabilities are built in. The PA-2A is easy to install and eliminates the installation of multiple bells, relays and paging cards." You will need to add a PA Horn (Industrial strength loudspeaker) to this. Sorry no surf report today. I think you also have to supply a 13. 5 V AC (60 Hz) power supply to drive the bugger, but check when you buy it. Get it from a telecom distributor, anyone but Graybar. I recommend Alltel (213) 692-9138 ask for Garth. They will do COD. So, the Viking PA-2A Multi-Line Loud Ringer, $86.00 plus a speaker will do the trick. Plus you get a paging amp as well for hootin' an' hollerin' at the help. These items are very popular out here in small machine shops and rag trade sweat shops. Yes, Esmerelda, there are other solutions, but this is probably the neatest and cheapest under the circumstances.

No great suprise there. Here's the background: for some unknown reason, PB has decided that if you want Centrex you *must* change your phone number. They have been refusing to grandfather in existing phone numbers for several months now. To console the destroyed business, they filed a provisional tarriff called "Number Retention Service." This turns out to be RCF with no usage charge. This allows the customer to "keep" their existing number. In fact the NRS (aks RCF) service forwards the calls to the new (possibly hidden) Centrex number assigned to the customer. The NRS service costs $50 install for 1-10 paths on the initial order, $50.00 per path install after initial order, plus $7.00/month/path and no usage charges (kind gift, wouldn't you say!?). Now this NRS can get quite expensive if the customer has say 10-20 existing lines and is in a CO where the switch doesn't do multi pathing on Call Forwarding. The conversation goes something like, "You can have Centrex, Mr. Customer, but it will cost you $70-$140 per month to keep your existing number (#lines X cost/path)." Some older ESS switches will multipath by default. I thought it was the 1A and the 1. I have been told that it is the 1A, 1E and/or the 1. I have a real customer in a 1E office where it does not work, but telco is insisting that it does work. Does anybody out there who might be reading this really know? I would certainly appreciate hearing from you. Trials with DMS and 5ESS show that multipathing does not exist. (As a side note, the NRS tarriff is outrageous as far as I'm concerned, and I would love to get some kind of protest going to force PB to either revert back to number preservation, or if NRS is required because of switch technical reasons, or planning, or whatever then PB should be *required* to charge one monthly fee and give multipathing as part of the service. This type of tariff really hurts small business the most ( <100 lines) ). MOK ------------------------------ From: Dave Horsfall Subject: Last Laugh!

There can be valid concerns about possibly prosecuters overstepping their authority and government abuse of power, etc. without condoning either piracy or theft. If these guys really ripped off source from AT&T or elsewhere, then they deserve what happens next, on the other hand, I can't really say that about people who run BBS systems that merely have the message passed thru their system, unknowingly. If the result of this "Sun Devil" operation is that private BBS owners start closing down their systems due to fear of prosecutors, and things like FIDOnet disappear, then America will have lost a valuable resource indeed, and Mr. Kapor may be correct in being concerned.

Being somewhat more charitable than PT, I assume two points in Mr. Kapors favor: 1) So far, at least, there has been no monetary loss shown by the various federal prosecutors involved in Sun Devil; they have alleged much in their self-serving statements to the media but, as has been pointed out in this forum, no actual damage of any kind has yet been substantiated. 2) I assume Mitch Kapor is reacting to the "witch hunt" atmosphere that seems to be pervading the LoD and Sun Devil busts - as witness the raid on Steve Jackson Games. Clearly, *somebody* needs to help the less-well- funded witch-huntees caught in the government's fuzzily-conceived trap. While it seems clear that there was some serious crackery going on, it seems just as clear that a *lot* of innocent people are being harassed by the authorities for no good reason except ignorance on the part of those authorities, are having their systems seized (to the detriment of some of the rest of us, in the case of e-mail relay systems), and are going to have to spend a lot of their hard-earned dollars on attorney fees just to point out the obvious in court. [Moderator's Note: Whether or not there is a monetary loss is of absolutely no relevance. If you don't think this is the case, then kindly leave your door unlocked tomorrow while you are gone, so I can come in and snoop around. I won't steal anything! I will just read through your personal papers, etc. Ah, you say, that is different! Not a bit. Why are AT&T, Sprint, MCI and similar fair game for the crackers and your home system -- or Mr. K's software is not? Now you go on to say a *lot* (your emphasis) of people are 'being harassed'. Name two or three; go ahead, I'll wait. You want to use Steve Jackson Games as one example? Ha! That's rich ... more and more news is coming out of that every day ... i.e. a little blurb in news yesterday alleging a cracker (I think previously convicted) was/is on his payroll. And you complain that innocent users on the net are being harmed by the disruption in mail: why is that the government's fault? Your complaint should be with the administrators of e-mail relays who have *violated the trust of the net community* by getting wrapped up in this stinking mess.

PT] ------------------------------ Date: Fri, 1 Jun 90 09:18:10 CDT From: Bill Nickless Subject: Re: Crackers: Innocent and Misunderstood, Says Mr. Kapor I can't believe it. Our Moderator writes that Mitchell Kapor, in offering to help some defendants in a court of law, is deserving of a boycott against his well-designed and written software package. Whether or not Mr. Kapor agrees with the actions of the people he defends should not be an issue. I have worked for a legal aid society, funded primarily by the United Way. Most of their casework involved defending homemakers who were being divorced by their breadwinning spouses and were in danger of losing everything, including their children. This is not because they were right or wrong, it was because they didn't have the money to fight the spouse with a job to pay the attornies. I believe Mr. Kapor has seen that there are some dangers inherent in the government's tactics in Operation Sun Devil. These dangers include the lack of common carrier protections for electronic mail and bulletin board operators. He has been (moderately :-) ) successful with 1-2-3 and would like to use some of his well-earned resources to ensure that the nationwide infrastructure of electronic mail and bulletin boards is not horribly disrupted, especially in a court case where the defendants do not have sufficient financial resources to counter the government's nearly infinite capability to pursue the matter. Whether or not the defendants did anything wrong should be irrelevant to this discussion. That is for the courts to decide. Mr. Kapor is simply trying to ensure that these defendants receive a fair trial. Bill Nickless [Moderator's Note: He said nothing at all in the {Washington Post} article about 'helping them get a fair trial' ... he said they did not belong on trial at all! Go back and read the article again. And whether or not they 'did anything wrong' is most certainly relevant to this discussion. It is what this whole discussion is about: whether or not you can take activities like cracking and twist it around into a wholesome, legitimate activity as Mr. Kapor suggests.

PT] After all the discussion on this, I can't believe you have such a bigoted, narrow-minded and short-sighted viewpoint! I'm absolutely astounded that you made such remarks, from many points of perspective. For example, you seem to imply that Kapor is supporting the theft from businesses, yet as we have seen, the Secret Service _ITSELF_ is guilty of completely disrupting the business of Steve Jackson Games. That really makes Jenkins' remarks look like the self-serving lies that they are. "...Threaten to disrupt our nation's business and government services"? Give me a break. If the situation was really that bad, and I honestly do not think it is, then I still would _NOT_ support abridging the Bill of Rights to crackdown on the criminals! Yet that is exactly what the Secret Service is engaged in doing. (And even more horrifying is that this sort of abuse of citizen rights and ignoring the laws of the land _by government employees_ is becoming so damn commonplace, what with the hysteria about "drugs" and the gross misapplication of RICO laws that every DA and his brother is trying out.) Furthermore, if there is a real nationwide telecommunications problem with vulnerability to criminals, it is most likely the lack of a good, national telecommunications policy that is most at fault! And that of course, once again, falls onto the shoulders of our elected officials. It may well be, though, that we are getting all the government we deserve, as someone so aptly put it -- electorate ignorance and apathy is so high that we get morons and crooks for elected representatives. To end that digression, though it is important, and to get back to your comments: it's obvious that the Secret Service and whoever else is involved is on a witch-hunt of the scale of that by the FBI during the late 60's and early 70's against those damn anti-war hippies. Even if the SS has caught up a number of extremely minor criminals in its huge fishing net, it still doesn't justify what they are doing. And this is` particularly true when the law regarding electronic communications networks such as BITNET, Usenet, and Bulletin Board Systems is so vaguely undefined at the moment. Is the administrator/operator of some carrier of electronic information completely responsible for every bit of data contained or passing through his system? The present legal answer is "No, well maybe, we don't know yet." We know the Phone Co. is not responsible. They're a Common Carrier. Are all Common Carriers exempt? I don't think so. Where do we draw the line? And here's where we run into a lot of problems, again, regarding` policy. Do we want to squeeze BBS's and Usenet right out of existence? We will, if we make the operators of the involved hardware responsible for everything passing through their system. Or do we want to promote a global electronic community with free speech and exchange of ideas and information? Or what? And then your suggestion that we steal software from Lotus or anything else which benefits Kapor financially is really a inflammatory strawman argument. Or a bad suggestion classing you with the worst of the criminals and hypocrits if you were serious. After all, there is _NO_ evidence in your remarks that Kapor is supporting criminal activity. Rather it seems he is against a campaign of terror orchestrated by the SS and AT&T and who knows who else directed at a lot of mostly innocent technophiles. Are you lily-white, impeccably honest, Mr. Moderator? I doubt it. And even if you were, you ought to be worried about the abuse of power that is taking place. Ever heard this parable? [paraphrased for brevity] A Methodist living in Berlin just prior to WWII watches as first his Jewish, then Polish, then non-Caucasian, then communist neighbors are rounded up and taken away in the middle of the night by the Nazis. Each time it happens, he does nothing, since the Nazis leave him alone. But when they finally come for him, there is no one to help him or protest his treatment, because they've already been taken. Do I need to spell this out for you? I hope not. There's a couple little clauses in the Bill of Rights regarding: innocence until proven guilt, freedom from unwarranted searches and seizures, freedom of speech, freedom to pursue happiness. Surely you are familiar with these. Having the Secret Service show up at your house, confiscate your computer, your media and what-not, and _NOT_ charge you with any crime is ridiculous! I'm not advocating theft. I'm not advocating that phreaker/cracker criminals go free. But how about the law enforcement officials stick to 2 simple rules: 1) follow the laws themselves, and 2) fit the punishment and enforcement efforts to the crime. Giving somebody a felony conviction, a 10 year jail sentence and a $10,000 fine for stealing something electronically (eg. the E911 operations manual) that would have been petty theft, had they just walked into someone's office at an RBOC and taken a printed copy off their desk, is seriously deranged. There seems to be a lot of hysteria involved here, and the popular press is responsible for a lot of it. But so are the ignoramuses, or are they fascists?, in the law enforcement agencies. We here certainly don't need to add fuel to the fire. How about level-headed objective consideration of the problem in its broadest and narrowest scopes? (I say that because everyone deserves to be treated as an individual, yet there is national telecommunication policy at issue here.) Oh, and incidentally: maybe it's a forgone issue now, but "hacker" is not a criminal or delinquint by definition, or at least, not originally, and not by most people who have pride in being one. But maybe the hysterics and popular press have abused this word for so long that it no longer has its original meaning. I regret that Mr. Moderator saw fit to use it as he did, unless it was merely a result of paraphrasing without thought some press release. ...Chris Johnson chris@c2s.mn.org ..uunet!bungia!com50!chris Com Squared Systems, Inc.

Aren't we forgetting the fact that some of those 511 channels that the Telebit uses are outside the frequency range that the telco promises? I think the telco says that you'll have decent output at something like 300 Hz to 3000 Hz (or is it 2700Hz?). I thought I read that the Telebit tries to use more of the frequency spectrum (like maybe up to 4000 Hz?). So if the channels outside the promised range are unusable, the telco isn't doing anything wrong, and the modem may not (at 88.26 baud) be able to use enough channels in-band to send at the higher bit rates.

I responded that maybe he did cover it earlier, but when something is stated in a way a non-techie cannot follow or is to be found so deep in a technical discussion that a non-techie will have given up reading it before getting to that part, it will reach only the other techies. I asked, DT> All you experts, please be tolerant if we ask for a re-explanation of DT> something in more common terms or if we don't realize that a question DT> is equivalent to one posed previously in thick jargon. Later in that same issue, Isaac Rabinovitch wrote, IR> My lack of experience in the telecom world leaves me without the IR> vocabulary to follow many of the interesting and important discussions IR> in this conference. Could somebody post a lexicon for the benefit of IR> folks like me? Pat Townson replied: PT> It would seem to me [that Isaac and David] have similar complaints, PT> and the answer for both may be to obtain copies of the glossary files PT> in the Telecom Archives. Look for the file entitled PT> 'phrack.glossary'. Providing definitions of the words and expansions of the acronyms cannot guarantee that everyone will understand the complete idea. In the questions I asked that led up to that submission and in the earlier articles that lost me, the problems were the concepts and assumptions, not the words or acronyms. I knew the words but the phrasing was ambiguous to my untrained eyes. As a result, I couldn't understand the answers as they were given. When I asked again, people repeated the same murky language. That didn't help. Finally (in one case very deep in other things I still couldn't follow) the answers arrived: (1) the frequency of a voltage meant the frequency at which the current is alternated; (2) REN's measure the line load for a device to detect an incoming ring signal, not the line load for its ringer to give out a sound, and therefore shutting the sounding mechanism off doesn't remove the device's REN load; (3) the REN limit of 5.0 per line is not a law and some lines can bear 6 or 7 REN's before ringer volume begins to weaken. Even at that, #1 and #2 came in only when I guessed them, asked whether that was what the writers meant, and was told yes. Pat's answer (pun unintended, but what the hell) applies to Isaac's problem but not really to mine. Both in TELECOM Digest and in comp. dcom.telecom, this forum is presented as a written medium. If we don't comprehend something, we can reread it until we've seen all the words a dozen times. If we still don't understand it, then the words need to be *replaced*, not repeated as if this were a spoken medium and perhaps we simply didn't hear you clearly the first time. So when someone doesn't follow the engineering or telephony jargon and asks for a re-explanation, it does no good to reuse the same type of phrasing that didn't get the point across the first time, nor does it help to fill the response with so much additional technical language that the answer, no matter how easy to read by itself, is drowned out by the new flood of jargon. At least please answer the question first (in different terms!) and *then* add the other highly technical thoughts that it brought to mind and which you'd like to say now. In the future, I'll try to make my requests for explanations multiple choice instead of essay if I can and, when I need something restated, to emphasize that I need it rephrased, not repeated.

Like most telecommunications services that belong to companies headquartered on the east coast, MCI has followed the unfortunate pattern of making the West last. As a former MCI employee in National Accounts, I can tell you that on the east coast, MCI connection are as good if not better than Sprint and/or AT&T. The reason for this is simple: MCI deployed their fiber and digital switches primarily in the Northeast corridor. MCI only has four major points at which calls are actually "switched" with the balance of their terminals simply acting as repeaters or pass throughs to one of the four switching centers. MCI had more subscribers per unit area on the east coast, and being a company hq'ed there, chose to make the majority of the "digital" investment there. I can still remember the analog microwave that was in service in California. Typical of being left to last, there was supposed to be only something like 30 miles between each repeater. Unfortunately, MCI ran out of resources and so there was something more like 80 miles between instead. Every time the fog rolled in near San Jose, there went the connections between LA and SF. In fact, one engineer figured that the signal was actually bouncing off the ground in between repeaters. Although there is fiber on the the California acquaduct, it is used primarily for private line, DDS and the State of Calif. There is supposed to be digital microwave from Richardson TX to the west coast (Richardson is one of the four magic points), but I have yet to get a digitial connection from Texas. Out here, MCI is definetely not as good as Sprint or AT&T, but out east it is as good technically. (As a side note about the west getting features last, you might recall an article that appeared here recently under the heading of "A piece of ESS history." The article pointed at a 1965 ESS deployment of an ESS machine *with* custom calling features available. Althought the first ESS was also deployed in LA in 1965, it wasn't untill about 1977 that custom calling was offered. At least that was the first year we were able to offer it to customers - I was also a Pac Bell service rep. --Excuse me, "Pacific Telephone.")

It's not really "Long Distance" service. New Jersey Bell and Bell of PA offer the same service in Philadelphia County PA and Burlington, Camden, and maybe Mercer Counties NJ. The service area is what would be considered "Local" if indeed "Local" and "Long Distance" were based on Geography and not Political and historical boundries. For this reason, the NY/NJ service is restricted to New York City and the adjacent counties in NJ only. As far as the exact nature of the tariffs, I suspect it's similiar to the rules that govern any "Local" Inter-LATA service. Since I don't know exactly, I would appreciate the answer to this question myself.

I tried a few things and here's a brief summary. 1. 60Hz line voltage through an isolation transformer. This would ring the (500 series) real bells, although more faintly at a faster frequency. The chirper I tried would kind of squawk. The modem (Hayes 1200) would answer, but when I added some nominal current-limiting resistors, it would fail to answer. 2. My second idea will sound like a real kludge -- it was. I half-wave rectified the output of the isolation transformer, and then using a circuit consisting of an RC network and a SCR, I passed every third cycle to the load. (I know this sounds exotic but it does work this way.) I level-shifted the output pulse to reverse-bias the gate of the SCR so that two of three pulses were blocked. This resulted in 20 100-some volt pulses out to the load. The chirper sounded fine, the modem answered, but the 'real' phone bell only tinkled a bit. :-( There obviously was not enough energy in the 20Hz portion of the spectrum to make it work properly. 3. My third attempt was to build a very simple two-transistor multivibrator using a center-tapped filament transformer backwards. I pre-loaded the output and tuned it by ear. (Scope -- manually selecting capacitors that gave a fairly stable 20Hz output.) With a load resistor and despiking capacitor across the output, I had a reasonably clean 20Hz almost-square wave signal. This worked with all three devices. I still use this today in combination with a simple plugboard when I have to key modems when I am testing software. With all of this conversation about ringers, I thought it might be interesting to some of yu. --- Through FidoNet gateway node 1:16/390 Jack.Winslade@f666.n285.z1.fidonet.org ------------------------------ End of TELECOM Digest V10 #406 ******************************   Received: from delta.eecs.nwu.edu by mintaka.lcs.mit.edu id ab16840; 2 Jun 90 15:06 EDT Received: from mailinglists.eecs.nwu.edu by delta.eecs.nwu.edu id aa29232; 2 Jun 90 13:35 CDT Received: from mailinglists.eecs.nwu.edu by delta.eecs.nwu.edu id aa16912; 2 Jun 90 12:31 CDT Date: Sat, 2 Jun 90 11:45:39 CDT From: TELECOM Moderator [To]: telecom@eecs.nwu.edu Subject: TELECOM Digest V10 #407 BCC: Message-ID: <9006021145.ab31811@delta.eecs.nwu.edu> TELECOM Digest Sat, 2 Jun 90 11:45:16 CDT Volume 10 : Issue 407 Inside This Issue: Moderator: Patrick A.

Fraser" Subject: Summary of Broadband Fiber Symposium On May 15, CAST (the Center for Advanced Study in Telecommunications, Ohio State University) sponsored a one day symposium: Broadband Fiber to the Home and Office: Economic, Political and Cultural Implications. The following posting, written by Thom McCain, Associate Director of CAST, summarizes the presentations. -------------------- The CAST Spring Symposium featured government, industry and academic perspectives concerning Broadband Fiber to the Home and Office. The May 15, 1990 session focused on the economic, political and cultural implications of fiber optics, coaxial cable and direct broadcast satellites for home and small business use. Participants were welcomed by symposium coordinator Thom McCain. The morning Keynote speaker was Robert Pepper, newly appointed Chief of the Office of Plans and Policy, the Federal Communications Commission. Pepper is also the author of the highly acclaimed background paper ``Through the Looking Glass: Integrated Broadband Networks, Regulatory Policies, and Institutional Change." Pepper reviewed the long and short range issues for the major player and the stakes which they hold in the development of integrated broadband networks. The players examined included: local exchange carriers, cable television operators; broadcasters; program producers/distributors; regulators; and users, including residential consumers. Representatives from three of the key players with high stakes in the future of telecommunications infrastructure each presented their industries' vested interest. All agreed that the primary use of broadband will be centered on entertainment video. Gary Nelson, Senior Director, Broadband Technologies, Ameritech Services, presented a compelling account of how broadband services will be brought to the home with a combination of fiber trunk lines and coaxial cable for the drop to the home. Brad Johnston, Senior Vice-President, Service Operations, of Warner Cable Communications, presented Cable's view of why their industry has the background and economic advantage to bring entertainment programming to the home, provided they are not hampered from doing so by restrictive regulation. Chuck Sherman, Senior Vice-President, Television, National Association of Broadcasters, presented a provocative and challenging argument to the Cable and telephone interests, noting that only Broadcasting has a legacy of bringing free television programming to the home. Sherman and the other industry representatives agreed that local advertising and programming will be part of whatever mix of technologies and players eventually emerge. In the short run all players were cautious about even the suggestion of cooperative efforts. The difference in their perspectives has much to do with the experiences each industry has had as a regulated industry, with varying degrees of monopoly status. While broadcast, telephone and cable service providers all see competition as central to their futures, each sees different bumps in the road ahead. These various roadblocks or impediments are seen as affecting the race unfairly for their own entry. Each industry will be less wary as the playing surface for this game finds its level. The afternoon Keynote was provided by James Carey, Dean of the College of Communications at the University of Illinois. Carey provided a stimulating and thoughtful charge to participants to reorient thinking about broadband technologies to focus on individual and societal needs and uses, rather than only commercial imperatives. His lecture ``Framing the Cultural Issues - New Technologies in Old Bottles" presented a series of concerns which communication professionals must confront in order to be mindful of the relationship between good citizenship, effective social relationships, educational needs and consumerism. As one participant put it ``Dr. Carey's comments puts tekkies like myself back down to earth, and I mean EARTH." The final sessions included a panel of experts representing a variety of perspectives and expertise related to design, economics, engineering, regulation, lobbying, marketing and education. They all used their experience to reflect on the future of integrated broadband network, by reacting to a newspaper ``The CASTigator," published in the year 2010. panel members included: John Fraser, Telecommunications Engineering Consultant, Christopher H. Sterling, George Washington University and Editor, Communication Booknotes, Dale Bring, Ohio Association of Broadcasters, Carol Caruso, Ohio Cable Television Association, and Mary Brandt, Public Utility Attorney.

I just got a bill for $100, about 155 calls over four months. The good news is that since they consolidated all those calls onto one bill, i got a $17 rebate from their volume discount programs. Somehow I don't think they'll go for it if I put their bill in my "error file" and wait four months to pay it. /eli ------------------------------ From: Todd Inch Subject: Genuine Bell vs Cocots Reply-To: Todd Inch Organization: Global Tech Int'l Inc.

Eric Townsend" Subject: Hacking/Phreaking/Cracking Tips From Cyberpunk Manual Date: Sat, 2 Jun 90 2:40:47 CDT Well, I rushed out and bought GURPS Cyberpunk, in the hopes that my money will help SJG with legal fees. (Plus, I collect game stuff.) On the front cover, in the SJG Illuminatus logo, it says: "The book that was seized by the U.S. Secret Service! (see p. 4)" Anyway ... (Assuming I know *nothing* about cracking/phreaking. I won't comment on my real knowledge.) The following is a summary of text from the GURPS Cyberpunk supplement, with a few direct quotes. How Much Hacking Can I Do Based on the C-word manual: (From the section entitled "Netrunning".) 0. People use handles to hide their real identity (p62). 1. You can uses sensitive devices to listen in on the signals being sent to a computer monitor, and redisplay the image on your own screen (p62). 2. General info on ISDN. (p64-64) 3. Computer accounts can come in various levels, from specialty logins (uucp) to "superuser" who has access to everything. Some programs can give you a higher level of access, equivalent to a "better" account (p68). 4. General info on back doors (p69). 5. General info on chat systems (p69). 6. A list of network names from around the world. No clues as to which are real. For the US, the following are listed: WUT, UDTS 2, Datel I & II, Telenet, Tymnet, ARPAnet, Infomaster, GraphNet, TRT, FTCC, UniNet, Autonet, CompuServer, GENIE, AlaskaNet, JANET, Internet (p 71). 7. Passwords can be really obvious, or hard to remember random text strings (p 72.) 8. A program could possibly cause physical damage (p 72.) 9. General Phreaking Info: - Diverters: go through a bunch of systems so that tracing takes a long time; - Junction Boxing: Just go down to the local junction box and tie in (p 76). 10. Lots of networks use different protocols that are sometimes incompatible (p 77). 11. Ma Bell stuff: - Existence of CN/A, and that Ma Bell can look you up in any way; - Line Routing: "With access to the main phone switch computer, a hacker can control everything about a specific phone line."; - Monitoring: a person could monitor calls with the right access; - After Billing: A person could change bills; (p 82). 12. Trashing: Go through somebody's trash to find out all sorts of interesting info about their computing equipment (p 86,87). (13 and 14 are from the section "Attack and Defense Programs". The programs are obviously s-f software, but ...): 13. Promote: "This program is executed from a normal user account on a system. If successful, the account is 'upgraded' to a superuser account." 14. Webster: "This is the standard icebreaker for use against Password programs (see p 93.). It acts as an extremely fast 'brute-force' hacker." (p 92). 15. Credcard Crime: A false balance could be entered in an account. A device could be used to access somebody else's card without having the correct password to get into the credcard (p 105). [note: a credcard is a self-contained debit card that can have anything from a password to retina scan protection.] And, um, that's about it.

NETEL's definition of an "apartment" is a living area with stove and bathroom. So... There is one Sysop of a local BBS here who has measured service lines installed all the time. To accomplish this, whenever he calls for measured service, when NETEL shows up to hook up his new line, he takes the little propane grill out of storage and sets it up. And, since his basement already has an extra bathroom, and his bedroom is down there too... voila! instant apartment.

Townson UK Telephone System [Clive D.W. Feather] ---------------------------------------------------------------------- From: "Clive D.W. Feather" Subject: UK Telephone System Reply-To: "Clive D.W. Feather" Organization: IXI Limited, Cambridge, UK Date: 29 May 90 15:23:14 GMT This document is my attempt to describe the UK phone system (i.e. those telephones within the +44 international area). It is based on information I have picked up over the years, but is not guaranteed. Telephone services in the UK are provided by the following organizations: British Telecom Mercury Communications Hull Telephone Company Vodaphone Cellnet For historical reasons, BT allocates area codes. This will change in a couple year's time. The bottom level of the BT system is the "Junction Exchange" (JX in this document). A JX is a unit which handles 10,000 subscriber numbers, numbered 0000 to 9999. A number may have several lines attached to it (hundreds in some cases). These four digit numbers are called LNs (Line Numbers) in this document. In a few rural areas, some subscriber numbers are three digits. The appropriate JX thus takes some LNs as being three digits, and some (possibly none) as four. Such JXs are being phased out. [This should be distinguished from the case where all LNs in a group of ten go to the same subscriber, and are interconnected. For example, Basildon hospital officially has the LN 2811. In fact, all of LNs 2800-2899 go to the hospital switchboard, and the JX will route the call as soon as it sees "28".] JXs are grouped into "Area Codes" (AC). Each JX has a one or two digit number within its AC - one digit numbers are being phased out. The exception is in "all-figure areas", where each JX has a three digit number. These numbers do not begin with 0 or 1. Each area code has a number. For most area codes, this is three digits, but for all-figure areas, it is two digits. The "number-space" for area codes is used as follows. All normal area codes begin with a digit from 2-9. The area codes for the all-figure areas are: Birmingham 21 Edinburgh 31 Glasgow 41 Liverpool 51 Manchester 61 London inner 71 (new) London outer 81 (new) Tyne & Wear 91 Of the 720 three-digit codes, about 600-650 are in use (I do have a complete table in numerical order, but it's not in machine-readable form). Certain codes have special meanings: 345 Calls charged at L rate irrespective of distance 482 Hull Telephone Company 800 Free calls 831 Vodaphone 836 Vodaphone 839 Calls charged at m rate irrespective of distance 860 Cellnet 898 Calls charged at m rate irrespective of distance Mercury has been allocated fifteen JXs in the 71 AC and the same fifteen in the 81 AC. I believe that all Mercury subscribers have numbers in this AC, irrespective of location. Area code 1 was used for London (both inner and outer) until 0001 on 6th May 1990; I am unaware of any plans for it. Area code 10 is obscured by the international access code. No area codes begin with 0 (but see below). From any BT subscriber, you can call any number by: 0 + area code + JX number + line number For example, anyone can call me by 0-954-78-0223. In addition, there are certain special codes: 010 international access 0001 equivalent to 010 350 1 [Dublin] 0055 from London only; calls charged at L rate 0066 from London only; calls charged at a rate 0077 from London only; calls charged at m rate Service codes begin with a 1: 100 operator 144 BT credit-card calls 151 fault reporting 153 international directory 155 international operator 192 directory Area codes are further grouped into "Charging Areas" (CA). For example: London CA: 71, 81 Cambridge CA: 220, 223 Madingley CA: 954 The exception is the Tyne and Wear AC, which is three CAs (JXs [24]??, JXs 3??, and JXs 5??). This AC replaced three separate ACs (whose numbers I have forgotten), each of which had its own CA. BT has five charging rates for UK calls, and seven for international. The UK rates, in increasing order of cost, are L, a, b1, b, and m (m is more expensive than I, which is the cheapest international rate). Rates also vary by time: peak = M-F 0900-1300 standard = M-F 0800-0900 and 1300-1800 cheap = all other times (these do not apply to international calls). All calls within a CA are at rate L, as are those to "neighbouring" CAs. Each CA has a nominal centre. For all other calls, if the CA centres are within 56km, the call is at rate a, and otherwise it is at rate b. Rate b1 replaces rate b where BT feels under pressure from Mercury (London CA to Cambridge CA is b1, but to Madingley CA is b). Rate m ("mobile") is only used for calls to Vodaphone, Cellnet, and the special area codes. Hull is treated as a normal CA. Calls from BT to Mercury are charged as normal calls to the London CA. The real complications (you thought this wasn't enough ?) come when dialling calls other than by the full 0+ sequence. For this you need to know the subscriber number (SN). The one simple case is the all-figure areas. For each area, lines within the area are identified by seven digits (JX+LN), and calls are made by just dialling this number [in Tyne and Wear, calls *between* ACs must be prefixed with 90; this is being phased out]. Everywhere else, we run into the "Named Exchange" (NE). An NE comprises a set of JXs, usually, but not always, in the same AC. A subscriber is identified by an exchange name followed by the SN, which is the LN with a prefix. The prefix can be empty, the last digit of a two digit JX, or the JX number. A catch to beware of is that sometimes two NEs have the same name but are distinguished by number length. For example, there is "Welwyn (six figure numbers)" and "Welwyn (four figure numbers)". These cover the same geographical area, but may have different ACs (these two don't). They are always in the same CA. As an example, the Madingley CA consists of: AC JX NE Prefix 954 78 Crafts Hill 78 954 21 Madingley 21 954 3 Swavesey 3 954 6 Willingham 6 954 5 Cottenham 5 954 4 Caxton (4 digits) none 954 71 Caxton (6 digits) 71 954 7 Elsworth none Calls to CAs other than at rate L are always dialled by the full 0+ method. To call a subscriber on the same NE, it is just necessary to dial the SN. Other calls within the CA, and to CAs which are at the L rate, may have an alternate dialling method (not necessarily: Madingley to Huntingdon is rate L, but 0+ must be used; all calls from AC 71 or 81 to any other (or each other) must be dialled as 0+). Two alternate methods seem to be in common use: the "fan" method and the "slave" method (my names). The "fan" method is used at the main NE of a CA. Several prefixes in its AC are not used, but instead become dialling codes from the NE. For example, from Cambridge: 8 -> AC 220 (same CA) 91 -> AC 440 (different CA) 92 -> AC 767 (different CA) 93 -> AC 954 (different CA) 94 -> AC 638 (different CA) 95 -> AC 763 (different CA) 96 -> AC 799 (different CA) 98 -> AC 353 (different CA) These are then followed by the JX and LN. All other NEs in the same AC (not the same CA) can be called by dialling the JX and LN with no prefix (there are no cases of this in AC 223). [Amusing side-note. Someone blew it in specifying 8 -> AC 220. The JXs that were in AC 220 (21, 23, 24, 26, 27, 29, 5) did not occur in AC223. So there was actually no need for the dialling code. All of these except the last two have now been moved to Cambridge NE (and AC 223) by simply changing the SN, without changing the JX+LN combination. The others will come soon (I have already seen people using "Cambridge 29xxxx" phone numbers).] The "slave" method is used at all other NEs in the same CA, and possibly in other CAs (All of Madingley CA is a slave of Cambridge NE in this sense). Calls to the master NE are made by dialling a single 9 followed by the SN. All calls which are rate L, and which could be made from the master NE with a dialling code, are made by dialling 9 followed by the sequence from the master NE. For example, from ACs 220 and 954, the following dialling codes exist: 9 -> AC 223 9+8 -> AC 220 (also used from Teversham (220 5) to West Wratting (220 29)) 9+91 -> AC 440 (not available from AC 954) 9+92 -> AC 767 9+93 -> AC 954 (also see below) 9+94 -> AC 638 (not available from AC 954) 9+95 -> AC 763 (not available from AC 954) 9+96 -> AC 799 (not available from AC 954) 9+98 -> AC 353 In addition, a slave NE may also have other dialling codes not beginning with a 9. For example, in AC 954, to dial from Caxton (six digits), Cottenham, Crafts Hill, Madingley, Swavesey, and Willingham to any number in the AC is done by JX+LN, without any code. On the other hand, to dial from Elsworth to Caxton (four digits), or vice versa, the route via Cambridge must be used (i.e. 9+93+JX+LN). One final note. Slave exchanges have operator service provided by the master exchange. This means that emergency service is "9+99". On master exchanges, it is thus simply "99" (! for UK readers). Clive D.W.

Townson Court Declares Caller*ID Illegal [Various Correspondents] ---------------------------------------------------------------------- From: TELECOM Moderator Subject: Court Declares Caller*ID Illegal Date: Sat, 2 Jun 90 17:30:00 CDT This past week, a court in Pennsylvania ruled that the Caller*ID service offered by telcos in that state was illegal. The telcos will most likely appeal to higher courts, including perhaps the United States Supreme Court for a final resolution. I received a huge number of messages from readers on this topic. Many were reports as they appeared in local newspapers around the country. In this special issue of TELECOM Digest, I have culled through the messages received, and present several. My thanks to all who wrote, and my apologies to the several messages I could not include due to space limitations, including but not limited to 'solomon@mis.arizona.edu' and Pete Ferris who sent the story as it appeared on the Associated Press wires. From: leichter@lrw.com [From the New York Times, Thursday 31-May-90, Page D1] Services Identifying Caller Held Illegal In Pennsylvania By Keith Bradsher A Pennsylvania court ruled yesterday that services that identify the telephone numbers of callers represent an illegal invasion of privacy. The verdict was the first in the nation on the legality of such services. The five judges of the Commonwealth Court, a mid-level state appellate court, ruled unanimously that caller identification services ... violate Pennsylvania's wiretap law. All five judges found that the services violate the law even when telephone companies allow some customers to block the release of their telephone numbers. And the court ruled by a 3-2 vote that the services violate privacy protections offered by the Pennsylvania Constitution. "In the framework of a democratic society, the privacy rights concept is much too fundamental to be compromised or abridged by permitting Caller*ID," Judge Doris A. Smith wrote in the majority opinion.... But Bell of Pennsylvania criticized the ruling. "Because of this decision, Pennsylvanians are being denied a service they eagerly want and badly need - a weapon against harassing, threatening or obscene calls," [a spokesman said]. Three Options for Panel The Commonwealth Court hears appeals of decisions by state and local administrative bodies in Pennsylvania, and its decisions may be appealed to the Pennsylvania Supreme Court. John F. Povilaitis, the chief counsel of the Pennsylvania Public Utility Commission, said his office would review yesterday's decision and make a recommendation to the commissioners within a few days. [He] said the commission had three options: to ask [for a rehearing], to file an appeal before the Pennsylvania Supreme Court, or to allow the decision to stand. Bell of Pennsylvania was not named as a defendant in the case. But [it] said it qualified as a party [and could appeal if the PUC chose not to]. Bell ... filed with the commission on June 18, 1989 for permission to offer caller identification. The commission approved the filing on Nov. 9 and the company scheduled service to begin Jan. 9. But a Commonwealth Court judge blocked the service pending judicial review. The suit was filed against the P.U.C. by the state's Office of the Consumer Advocate, the [ACLU], the Pennsylvania Coalition Against Domestic Violence and the Consumer Education and Protective Association. [Caller ID is now] widely available in [five states] and on a limited basis in [three others] ... according to ... a spokesman for Bell Atlantic Corporation, the parent of Bell of Pennsylvania. Phone companies in nine other states and Washington are seeking to introduce caller identification. Long-distance companies, including [AT&T], also offer caller identification to some businesses with 800 and 900 numbers. Yesterday's decision ... did not address whether long-distance companies should stop providing information for Pennsylvania callers. "We have to see how, if at all, this ruling affects AT&T," said ... a spokesman for the company. Privacy Issue Cited Bell Atlantic and other defenders of caller identification have argued that the services discourage obscene callers and protect the privacy of people receiving calls by allowing them the choice of not answering. But the court ruled explicitly that the privacy of people making calls is more important. The court found that caller identification services function as call-tracing devices, which under the Pennsylvania wiretap statute may be used only under certain circumstances. The court noted that Pennsylvania requires the consent of all parties before a telephone conversation may be recorded. As of December, there were fifteen other states with similar requirements. The remaining states and Federal law allow taping with the consent of one party. But [FCC] rules require that all parties to an interstate or international call be aware they are being taped. The Pennsylvania wiretap statute contains wording similar to the Federal wiretap statute. Bills are pending in the House and Senate that would amend the Electronic Communications Privacy Act of 1986 to make caller identification explicitly legal while requiring that telephone companies give customers the option of blocking release of their telephone numbers. A subcommittee of the Senate Judiciary Committee has scheduled a hearing for June 7 on caller identification. -------------------------------- Next, we have a report from the {Philadelphia Inquirer}: From: "Scott D. Green" Yesterday, Commonwealth Court ruled that Caller ID violates the state's Wiretap Act and the caller's constituional rights to privacy. Judge Doris Smith ruled that obscene and annoying calls can be dealt with using existing Bell services. Bell of PA will study the ruling to decide whether to appeal to the state supreme court. Opponents of CallerID (ACLU, PA Coalition Gainst Domestic Violence, et al) went to court only to get blocking for any customer who wanted it. The decision said that CallerID violates the Wiretap Act, with or without blocking. Bell's VP for Ext. Affairs said, "Because of this decision, Pennsylvanians are being denied a service they eagerly want and badly need." The company said that the ruling would force them to remove CallerID from police and fire emergency lines. [A threat, perhaps?? -sg]. ----------------------- David Gast makes an excellent suggestion, after paraphrasing the story as it appeared in the {New York Times}: From: David Gast The NYT reports in Thursday's (May 31, 1990) edition that a mid level PA court has ruled that Caller Id is an illegal invasion of privacy. All five of the justices found that the services are illegal under PA wiretap laws even if some customors can block their phone numbers from being sent. The justices split 3-2 in favor of ruling that caller ID violates the privacy protections of the PA state constitution. An AT&T spokesmen said that he would have to look at the ruling to see if it affects 800 and 900 caller identification programs. David Gast gast@cs.ucla.edu {uunet,ucbvax,rutgers}!{ucla-cs,cs.ucla.edu}!gast P.S. Since I tried extremely hard to avoid editorializing (that is, commenting on whether I believe the decision was good or bad), I suggest that follow-ups be made to some other newsgroup like misc.legal. ---------------------- Wayne Correia sent this report from the {San Jose Mercury News}: From: Wayne Correia 5/31/90 SJ Mercury News CALLER ID SERVICE BREAKS WIRETAP LAW, COURT SAYS PHILADELPHIA - A Pennsylvania court said flatly Wednesday that any form of Caller ID, a proposed Bell of Pennsylvania service that would allow customers to see the phone numbers of callers, violates the state's Wiretap Act and callers' rights to privacy. Civil libertarians applauded the Commonwealth Court ruling - which went further than Caller ID's most vocal critics had asked for - and said it might spark challenges to the service elsewhere. Bell of Pennsylvania said it was "extremely disappointed" with the decision and might appeal to the state Supreme Court. Caller ID has aroused fierce debate in Pennsylvania and other states where it is being introduced, with both sides arguing that they are trying to protect privacy. The service permits phone customers who pay a fee and who have the right piece of equipment to see the numbers of callers before answering the phone. Telephone companies and others in favor of Caller ID say it is like a peephole in a front door, letting customers decide whether to answer their phones and protecting their privacy. Others say it sacrifices the privacy of people with unlisted numbers and might discourage people from making anonymous call to the police or other investigators or crisis hot lines. Consumer groups went to court to try to get number-blocking for any customer who wanted it, which Bell said would defeat the purpose of Caller ID. Other Bell companies are testing or introducing Caller ID in a number of other states but often are running into the same debate that surfaced in Pennsylvania. ------------------------- [Wayne then added this personal note at the bottom of the newspaper story.] I guess they don't know that organizations with Primary rate ISDN trunks and Feature Group D 800 lines currently receive the CPID and ANI respectively of the phone number calling them. Maybe technology will win over emotion next time. I wonder how much a PRI ISDN trunk and a corresponding Panasonic PRI ISDN trunk card for my PBX would cost me? (if it were available!) :) Wayne Correia wdc@apple.com --------------------------- A thread started recently in the Digest discussed 'self help' ways of blocking Caller ID.

The decisions of this court can be appealed to the Pennsylvania Supreme Court. The PUC can also ask the court to hear the case again within fifteen days or let the decision stand. It's not clear how this will affect the 800 and 900 ANI services offered by long distance companies.

Mark Kallas ------------------------------ From: David Lesher Subject: Summary of Florida PUC Meeting on Caller ID Background: SBT wants to start selling CID on 5 June for $7.50/month. They do NOT want to supply blocking at all, but have relented for police officers and domestic violence workers. {Disclaimer: This is from memory. I did not take many notes, and so I may have some names spelled incorrectly. A transcript is available from Mr. Shreve's office.} The 30 May meeting regarding Caller ID was slightly stormy. It was called by Jack Shreve, the state Public Counsel. His office represents utility consumers before the PSC. It was not well publicized, but about fifty people attended. 'PRO' speakers included SBT, a Palm Beach businessman who talked about the ability to monitor customer's buying patterns by phone number and a woman from an organization called PATT (I think), in Maryland. (I'm not sure who paid her travel expenses, but the person next to me mentioned that she has been to several states and on the Hill testifying about it.) The first ANTI speaker was from the Florida Medical Association. He talked about the concern of the medical community in regards to returning patient's after hours calls. He pointed out that all of the alternatives SBT suggested (cellular, operator assisted, separate outgoing line) would cost the subscriber extra. SBT suggested they may offer a new blocked METERED outgoing line to MD's {note: to the best of my knowledge, there are no metered/measured lines in the FL tariffs at present) Another ANTI speaker was from a volunteer group whose members are appointed by a judge to represent the child in custody/abuse cases. Mr. Ellington of SBT suggested she contact her HRS {ie state welfare system} representative. {SBT has already offered HRS employees blocking}. She pointed out that her organization has NO connection with HRS at all, and in fact they often oppose HRS in these cases. But the largest contingent was from the law enforcement community. Mr. Ron Tudor of the Florida Dept. of Law Enforcement pointed out the many problems involving the law enforcement community. He also talked about the large amount of CID equipment being found in raids in other states. An Assistant State Attorney mentioned the fact that prosecutors and judges face the same problems as police officers. {SBT has NOT offered them blocking} Several other PD officers from various agencies also spoke. {Mr. Tudor is on a FSLE committee that is studying the entire problem. I gathered this study is a major effort. I got this impression when he showed up with, and started quoting, Bellcore spec's. No disrespect, but I work with lots of cops, and I never before met one that knew Bellcore existed ;-( } Mr. Robert Sherman, a free lance photojournalist, talked about the similar situation he would face. He wondered if {Watergate's} Deep Throat would have ever called the Post with CID around. The meeting ran well over its time slot and concluded about 1900. Mr. Shreve announced he was considering holding more such meetings before deciding his course of action. Final notes: a) The FLA PSC is supposed to decide on 5 May. I would *guess* that they will stall. b) There was some media coverage (2 rx people, and at least one rag) the latter because there was a story was on B-1 of the Herald the next day. The focus of the story was the controversy, and the differing viewpoints. wb8foz@mthvax.cs.miami.edu (305) 255-RTFM pob 570-335 33257-0335 --------------------------- Further news developments will be reported of course, but as David Gast suggested, misc.legal might be a good place for followups.

My suggestion is that the discounts should continue, for perhaps a maximum period of another eighteen months -- say, until January 1, 1992. During the interim period, an effort would be made to convert as many TDD users as possible over to high speed modems and 'BBS like' software, so that for all practical purposes they could participate in the world with the rest of us. I'd even go so far as to say the money presently allocated for relay services and the like could be partially used to subsidize the purchase of inexpensive terminals with high speed modems. For those deaf persons who already had computers and modems, some software would be available at a reduced (if necessary) price. Then following the cut off date, no more discounts for slowness ... or maybe, a much smaller discount at present, which would go on for a few more months of the coversion, then a final end to it. That's just my solution; it seems a fair way to end the costs others are paying while still lending help to our deaf citizens. To bring a close to this topic, this issue has three more final comments, including one from the person who started the thread. Patrick Townson ------------------------------ Date: Fri, 1 Jun 90 16:36 EST From: "Curtis E. Reid" Subject: TDD Discount: My Response I've been away on vacation and imagine my surprise the "flame war" that I started! :-) Okay ... from the articles that were posted in several issues of TELECOM Digest, it appears there are several major issues that were raised in response to my concern that AT&T might discontinue the TDD discount for deaf customers. These issues that the readers brought up are indirectly and directly related to the use of TDD discount. Allow me to explain the reasoning why AT&T deaf customers have TDD discount. It is *not* a discount per se (like 50% etc.) but rather use of time-of-day rate at the time of call made. I.E., if I call during the daytime (Day Rate), I get billed at the Evening Rate. If I call during the evening (and Evening Rate), I get the Night Rate. Likewise, if I call during the Night Rate, I still get the Night Rate. And, they are all direct-dialed. The following schedule for direct dialed inter-state calls is pretty common in many states: Time Actual Called Rate Actual Billed Day Rate ---> Evening Rate Evening Rate ---> Night Rate Night Rate ---> Night Rate Some states also offer similar rate schedule like above for intrastate calls; although I do not know what PacBell, SouthWest, and other companies offer. I'd like to hear from readers who might know about it in those areas. And, the most common restriction regarding the TDD discount is that it is offered only for one residential line. So, if you have a couple residential lines, you get the TDD discount only on one line. If you think you can get these discounts on multiple lines, forget it. And, AT&T must be your primary long distance carrier. Another thing, you must fill out an application and have it signed by an physician or audiologist to certify that you are hearing impaired, you are unable to hear or speak well to communicate aurally, and you rely on TDD. The telephone company that processes your application will call you on TDD to verify that you do indeed have a TDD to answer. These procedure may vary in some states and local telephone companies. For example, Rochester Telephone Corp. is probably the most unique in the country because it uses a calling card billing to give TDD users a TDD discount. Apparently, their billing system cannot handle the discount on direct-dialed (1+a/c+nbr) so the workaround is to use the calling card with a special prefix 534. This practice has continued for many years and it seems likely that Roch Tel will not modify their system because AT&T will soon be doing its billing in July or so. Back to my concern that I addressed earlier, I was concerned about the news that AT&T might consider removing the TDD discount because no other long distance carriers (MCI, Sprint, etc.) carries this discount. So, the idea is if they don't carry the TDD discount, why should AT&T? I contacted AT&T but they deny or plead ignorance so I don't know whether it will be implemented when they do the billing later this year. I simply hope this is just a pure rumor. To address other concerns of issue: Why should deaf customers who use TDD get the discount? Why don't they upgrade TDD units to 1200 or higher bps? Are deaf people really economically disadvantaged? Is the TDD discounts fair? I think all these pretty sums it up what readers have posted to TELECOM Digest. I'll answer each questions and you can tell me whether you agree or disagree but let's not start a flame war, please. Why should deaf customers who use TDD get the discount? If you look at the rate schedule I mentioned earlier, there isn't really any additional discounts -- just a shift of the rate with time of the day. But, the real answer, that some of you have already answered, is that a communication via TDD takes two to four times longer depending on the user's typing skills. Even at 45 WPM is too slow for me but it is the fastest TDDs are designed to handle. Some people type slower than 45 WPM. This is an equitable way to equalize the cost of a voice call versus TDD call. To give you an idea, if I spoke the following sentence "Mary had a little lamb.", it will only take me five seconds to say it. Now, if I typed that on a TDD, it takes fifteen seconds. Now, for fun exercise, record a five-minute conversation with another person. Just five minutes. When you are done, play back the conversation. Repeat the entire conversation by typing it into a computer or typewriter. Record the time start and time end. When you are done, figure how long it is. Add another twwo minutes for pausing and "GA"s. That's how long. My guess it is between fifteen to twenty minutes or longer if you speak fast. Why don't they upgrade TDD units to 1200 or higher bps? I encourage the use of ASCII and higher speed. Unfortunately, TDD is a 1960 technology which uses the outdated BAUDOT code (5-bit) and there is a large installed base of approximately one million. Many people have invested in TDDs and consider purchase of a TDD to be significant. So, residential TDD customers would rather keep their TDDs as long as it is still working. When it breaks down after five to seven years, then they'll buy another TDD. So, the cycle repeats. I feel that this will continue well into the 21st century. Until they are willing to use ASCII instead of TDD to communicate, TDD is here to stay. Are deaf people really economically disadvantaged? I would say between 75%-80% are economically disadvantaged. The rest are well-to-do with good income. But, for the most part, they live between poverty and low middle income. (I consider less than $13,000 to be poverty.) So, they have to eat which takes up about 40% of their income. Rent and taxes are two other major expenses. So, there isn't much room for luxury items. As far as I know, there isn't many deaf managers in corporations or in executives. Oh, I'll say there are in high-level manager positions but it's few and far between. Every penny counts. Is the TDD discounts fair? To regular customers like yourself? That's a matter of opinion. Some say it's not fair because it subsidize deaf people. Who is to say it's fair that blind people get an extra exemption on their federal income tax return? Who is to say it's fair that the elderly gets LifeLine service? Alas, the world is not what we'd like it to be. There are so much prejudice and bias that the government has to assist those disadvantaged. If *all* the companies would hire blind, deaf, physically handicapped and others equally and equitably then we won't have any problems with subsidization. Until that day that everyone would be treated equally (and it is coming soon now that the Congress is close to passing a civil rights bill for the handicapped that prevents discrimination in employment and other places), subsidization is necessary. Consider yourself. What kind of job are you working? Is this job something a deaf person can do? What about your friends? Are they receptive to deaf or handicapped people? I can go on and on but I'm sure you get the idea now. I know I'm at the risk of starting a discussion on the merits of deaf people versus other people and the use of subsidization. Please bear in mind that I'm writing in response to some of the comments/remarks that some of you made. What I have said earlier represents my views and opinion and is in no way represents the opinions of *anyone* else. Well, that's it from me. TDD specs and history are in the Telecom archives if you want to look further into it.

I tend to wax philosophical, so bear with me... As a professional, I agree with John Gilmore that rewarding inefficient transmission with lower rates seems counter-intuitive, and I can understand the appeal of Libertarian arguments to put everything on a pure pay-for-yourself basis. But Karl Denninger is correct when he writes that: >However, the issue is not >bandwidth, nor is it the information able to be transmitted per unit >of time. It could be a matter of perceived public service, or any one >of a number of other factors. It's simply impossible to consider technology in isolation; economic, political, and moral considerations all contribute factors that are almost always far more important. I learned this many times over while working on our Deafnet project and participating in the PUC hearings for California's TDD distribution program, and got so depressed and burned-out by this exposure to reality that for several years afterwards I had no interest in bashing my head any further. Technological: High-speed data standards, batched e-mail, VLSI modems and other technological fixes are fine and dandy, but the concepts were not new twelve years ago when we demonstrated all of them. Exercise for the reader: Why do you think they haven't happened? Analogous exercise: why don't we have HDTV yet? Economic: Are the deaf economically disadvantaged? In general, yes. Anecdotal evidence might work for Reagan, but not in this forum, I hope. Regardless of many well-off deaf professionals you know, the data from real surveys is not encouraging. In general, the level of income for deaf people is below that of the hearing population; for the prelingually deaf the differences are more severe. One of these differences is a 6th-grade reading level, which is not exactly a ticket to fortune (once again, movie stars notwithstanding). While my own experiences as a WODP must be considered equally anecdotal, they are consistent with these surveys. And were a rude shock, I might add. Political: Why should some groups be subsidized? A good question, which should be applied to everything else such as local and rural telephone services, hospitals, insurance, mass transit, PBS, and space launchers. Whether we like it or not, the representatives of our society have already decided that subsidization is an acceptable method to promote the greater good, and if you are arguing against this concept, you are taking a radical position indeed. In this particular case, I believe some form of help for deaf telephone users does indeed promote the greater good, but as for most other subsidies it is hard to come up with definite proof of this. We make do with appeals to emotion, reason, and greed. I don't know how the rate discount evolved. I do know that the TDD distribution plan in California was heavily influenced by TDD manufacturers who expected to gain a windfall profit from sales to telcos. The situation of deaf people provided the emotional sugarcoating that made the vendors' motives palatable to the legislature and PUC. Whether the equipment served the needs of the deaf was secondary to whether it served the needs of the vendors, the PUC, and the lobbyists thereof. In retrospect, just normal politics. Moral: Modern western culture appears to have developed a general philosophy that it is a Good Thing for advantaged people to help disadvantaged people. Aside from religious motives, this can be justified both on the selfishly personal grounds that you never know when YOU will become one of the disadvantaged, and the more noble but long-range faith that it will contribute to society as a whole. I use the word "faith" because even when the economic numbers demonstrate the advantages of things like subsidization, it's hard for most people or businesses to think in such long-range terms. Why should your money support my telephone usage? Why should my money support your PhD at Enormous State University? Why am I wandering off the subject? In sum: Personally I think that the additional traffic and business generated by providing telephone access to the deaf will far compensate for the "subsidization". I don't think the rate discount is a particularly well-conceived approach to the problem, but the other aspects (TDD distribution and relay service) are essential. The telephone has become such an enormously important and crucial part of our society today that any group which is prevented from using it, for any reason, is indeed severely disadvantaged. I just wish that it was easier to get technology out of the lab and into the real world.

Does it work elsewhere ? Your number is being passed (via ANI) to TOPS. TOPS *should* pass the caller's number back to the originating CO via ANI. If the originating CO has SS7 or ANI trunks to the 800 carrier, then the originating CO *should* forward your number to the 800 carrier. Possible causes : 1. TOPS is not passing the digits back to the CO; 2. the originating CO does not have ANI/SS7 trunks to the 800 carrier; 3. the originating CO does have such trunks, but for some reason is not forwarding your number. Since your number does usually get passed on, that should rule out #2. Someone who knows more about TOPS could address #1. If you know what type of CO you are served by, we might be able to address #3. -- ------------------------------ From: "Stephen J.

PEP is modulated at 7.35 or 88.26 baud PER CARRIER, and to get the baud for the whole signal one must multiple by the number of carriers in use.

I remember the first Bay Area ESS cuts as being around the very early '70s. (I started noticing the "precise" ringback tone, and the funny way when someone answered, the RBT would stop almost a full second before there was the clunk of the audio path being completed.) Anyway, it was not more than a year before the first basic features were offered: three-way, forwarding, and call-waiting. Speed calling didn't become available until something like 1976, but there were definately the other features available years before that. This is extra odd, since it has been my experience that ALL technological improvements in Pac*Bell (or Pacific Telephone, depending on the era) come to the Southland years before anywhere else in the state, including the Bay Area.

PT] Carl- Actually, the 1/1AESS's in Queens and Brooklyn (718) New York allowed 1+ and 0+7 digit dialing for a while, and the same problem came up. One could dial 0+403-9970, and the payphone would wait for a few more digits. (Or you could dial 0-403-555-1111 or whatever, and it went straight through...) I found that using the "#" sign at the end of the seven digit number would tell the exchange to immediately process the call, rather than wait for the timeout (I think someone on the Digest mus have mentioned this allready, though..). The odd thing was that you were also able to dial 1+ 7 digits for local calls to SOME areas. IE, you could dial 1+336-9950 from a 718 1AESS in Queens to reach (then then 336 1XBar (?)) in Brooklyn, which was a local call. Yet you weren't allowed to dial 1+ to reach other exhanges nearby, ie also local (718-643, 398, etc...) Since I wasn't too familiar with where any of the 'towns' in Brooklyn are, I assumed that the 1+ calls were historically toll calls, and the ones which refused 1+ were not. When I found out that some of the exchanges which accepted 1+ before the seven digits were CLOSER to me than the ones which did not, I called NY Tel to ask why this happened. The rep said that they NEVER charged toll rates at any piont in time to those areas (all of NYC, except Staten Island, was "local" since the late 1940's, it seems...), and that it was a mistake that the calls accepted a 1+ first. A few weeks later, the 1+/0+ thing no longer worked, which I guess shows you not to complain to NY Tel! (You can still try the timeout thing though, by dialing 0+AC+#, after the card # is accepted dial "#", and place a new call to 403-9950. The Calling Card equipment will wait for a while to see if you time out, and then put the call through to 403-9950. Of course, you can always enter the "#" key before you hear the "Thank You" (no "...for using AT&T" since it's local and it's a 'sequence call'...) which will put the call through immediatly. I think you can still do 0+7 digits in the 415 area (Bay Area/SF). But then I'm not sure whether they have any exchanges that look like area code in the 415 area yet (ie, N0X/N1X exhcanges)...

On May 31st, Alberta Premier Don Getty said the government would sell half of the company, and it would offer Alberta residents the first chance to buy shares. No more than ten percent of the shares could be owned by non-Canadians. Complete details (when, share prices, etc.) weren't announced. However, the {Globe and Mail} (a Toronto newspaper with a strong emphasis on business and political coverage from which I got most of the information for this article) mentioned a value of $3 billion for AGT. Traditionally, AGT was regulated by the province. A recent Supreme Court of Canada decision said that the federal government could take over regulation of AGT (and of SaskTel and Manitoba Telephone System, two other telephone companies owned by provincial governments) by passing appropriate legislation. Since the provincial government will no longer have the ability to set rates and investment patterns for AGT in the interests of whatever Alberta groups it wants to serve, the need for Alberta to own its own phone company is somewhat diminished. The only other phone company in Alberta is 'Edmonton Telephones', a department of the City of Edmonton. Unitel Communications Inc. (formerly CNCP Telecommunications) competes with AGT for some long-distance and enhanced services, but is not allowed to provide message toll service (individual long distance calls). The political opposition isn't impressed, calling the proposed sell-off a mistake. New Democratic Party leader Ray Martin was quoted in the {Globe and Mail} as saying that the sell-off would cause the cost of telephone service to soar, and would cost AGT the tax-exempt status it now has as a government-owned company. I don't know whether the provincial governments in Manitoba and Saskatchewan, or the city government in Edmonton, are considering selling off their phone companies, but they'll obviously be watching the AGT privatization with great interest. ------------------------------ From: Nigel Allen Subject: Ontario Communications Minister Resigns Reply-To: ndallen@contact.uucp (Nigel Allen) Organization: Contact Public Unix BBS.

An opposition member of the Ontario legislature said that a week before her resignation, Hart had asked the Ontario cabinet to support Unitel Communications Inc.'s bid to compete in the long distance service market. On Wednesday, in explaining her decision to quit the cabinet, Hart said it was a mistake to have anyone employed at a telecommunications company working on her nomination. The potential for conflict of interest might arise, she said, because her ministry (its Communications Division, actually) acts as an indirect regulator when it takes positions on issues with the CRTC.

The cost of a call to Vodafone or Cellnet mobile phone numbers is determined by the digit after the area code.

As with Mercury, a proportion of the income from these calls is given to the service provider. At present calls are charged at 25p / min peak and standard rates and 38p / min cheap rate, including VAT. Of this, 17.5p, excluding VAT, is passed on to the service provider. Vodafone also carries revenue sharing services, using the 8364 prefix.

The 01 prefix is now almost certain to be used for variable charge revenue sharing services - like the US 900 numbers. This cannot take place until a greater proportion of the BT network is digital.

These were revenue sharing services. They weren't only available from London, but any city with a Derived Services Network centre. This is a network separate from the main BT network, which carries 345, 800 and 898 numbers. It has its origins as an early trunk network, I believe. 345 and 800 have now been switched over to the Digital Derived Services Network from the old analogue DSN. This uses AT&T 5ESS switches, allowing wide flexibility in call routing. Customers can choose to receive a certain percentage of calls at a different locations, changing depending on the time of day, for example. 898 is currently undergoing conversion to the DDSN.

Just FYI. That's because 310 isn't an NNX area code: "N" represents digits 2-9, so 310 is still an N1/0X, in standard jargon. The list was only of the NN0 codes they will assign. It is still an interesting question, though, which N10 codes they're going to use in what order after 510 here in Berkeley and 310 there in L.A. Will they use all eight of them before starting the NNX's, or will they intermix them, like they did with 510/310 before 917/909?

As for it being obvious what some German bureaucrats think about the German/Polish border, the source document cited in the article seems to date back several decades, when the German postal code system was set up, and not reflect anyone's thinking today. Mr. Reed even quotes the magazine article referring to a DBP bulletin 'SOME YEARS AGO", and if it uses the phrase, "so-called GDR", which has been out of official use for some time, it would, as he himself pointed out, date back to the 50s or 60s. It has already been reported here that the DBP Telecom has area codes (not codes for exchanges) set aside for the territory of the DDR.

PT] Speaking of the local phone book, I've noticed something the last few years: the list of foreign codes has gotten SHORTER and SHORTER each year -- I guess the idea is that Pac*Bell doesn't get much revenue *directly* from international calls, so they won't put much effort into helping you. For example, the Oakland book lists 38 country codes and a total of about 83 city codes, for the entire world. The omissions are rather strange, too: Finland is listed but not Sweden. Other notable omissions are Turkey, Egypt, Argentina, Thailand, and all of Africa except South Africa. Vatican City and Monaco rate listings as country codes, but not Saudi Arabia. Our Swedish friends will be happy to know that they are the only country the San Francisco directory adds to Oakland's list, with 5 city codes (second only to UK).

We both agree that everyone should have a fair trial; and that no one is officially guilty until the court has so ruled.

Telecommunications have played an important role in the democracy movement in China. Here are two stories, one is about a dissident arrest tipped by his LD call, and the other is the escape of a dissident thanks to telecommunication. Report One: A Trunk Call Led to A Prominent Chinese Dissident's Arrest ---------------------- No one knew exactly how Mr Wang Juntao, a prominent Chinese dissident was arrest until one of his colleagues escaped from China to US recently. She told several newspapers the following story. "Juntao hid in Beijing for a while following the 4 June incident. With the situation getting tense, he finally decided to go south in an attempt to establish contact with overseas rescue organizations. However, we lost contact with him soon after his departure from Beijing and were even unaware of his whereabouts. We eventually knew about his arrest in Beijing from a classified bulletin circulating within the provincial and army levels which noted that Wang Juntao, an evil backstage manipulator of the rebellion, had been captured. The classified bulletin also disclosed that Juntao fled to Changsha, the capital of Hunan Province. There he failed to get in touch with members of the local student movement. He felt quite hopeless and made a trunk call to Hong Kong rescue organization, at great risk, to request rescue and for him to be sent the necessary travel documents." "Before long, a self-claimed Hong Kong rescue organization rang Juntao, saying that rescue work would start soon at a cost of about 10,000 yuan. Juntao said he had only 8,000 yuan or so. His counterpart said in reply that money was not so important and they had to meet as quickly as possible to discuss how to flee. Both sides then agreed that they would meet in a coach of a train bound from Changsha to a certain place because Juntao did not tell his counterpart where he was staying. When Juntao entered the coach on schedule, he immediately noticed something wrong -- other coaches were very crowded but there were only a few people in the coach he entered. When he tried to open a window to jump out public security personnel in plain clothes, hiding inside and outside the coach, all drew their pistols from their pockets." Apart from what she had learned from the classified bulletin, she heard two other versions of Wang's arrest in Beijing. One was that the the authorities had installed the most advanced tapping device in Shenzhen, which can monitor all trunk calls from Hong Kong to the mainland. The other was that Chinese special agents in overseas rescue organizations divulged secret information. Report Two A Direct Dial Call Rescued A Chinese Dissident --------------------- A famous Chinese writer and dissident found his way fleeing out of Beijing after the June 4th Massacre, and arrived at Guangdong (Canton), a big city close to HongKong. He tried his best to escape to HongKong, but only found that all the roads were paroled by soldiers around clock and check-points were set up at main intersections. Several weeks past while he was keeping desperately looking for a way out to safety. He dared not to call friends for help as he realized all long distance calls at the public phones had to go through operators who usually had the order to monitor the conversations (mostly not for connection quality, but for counter-revolutionaries). One day on his move from one hiding place to another, he was delighted to see a billboard at a new phonebooth saying that, with the advanced techniques provided by a foreign company, this particular phone could dial overseas directly without operators. So, he came back at night and called a friend in HongKong who, he believed, must have contact with local democracy organizations. The next day, a person came from Hong Kong and took him out to freedom. This story was said by the writer himself at a meeting here at U of Alberta. Shuang Deng (shuang@cs.Ualberta.CA) ------------------------------ From: Jerry Aguirre Subject: Are DID Trunks Incoming Only? Date: 31 May 90 22:31:06 GMT We are in the process of ordering DID, a 600 number block. When costing this out we were thinking of converting our existing trunks over for DID use. Now the local carrier, PacBell, is telling us that DID lines are for incomming calls only; we can not use them for making calls. This is going to require us to keep a separate group of trunks for outgoing calls with no overlap of the two groups. That means the total number of trunks will have to be larger to handle peaks in incoming and outgoing calls and that means more trunk charges and more trunk interfaces for our PBX.

The telephone company (Alberta Government Telephones) runs a talking yellow pages service, with the usual stuff on it, 403-521-5222. The transit system runs what appears to be a DID-based automated bus schedule. One or two numbers are assigned for each bus stop, and a synthesized voice reads back arrival information. An example: 403-260-5281. Others apparently lie in the 5000 and 6000 blocks of the same exchange. The transit system main information number is 403-276-7801. This is not automated.

I have just been informed that the 5ESS that is soon to be installed in the office will replace only the X-bar, not the 1E. Why? It turns out that anywhere else in the country the entire office would be converted to the 5E, but not in California. The PUC seems to be of the opinion that "if it ain't broke, don't fix it." This explains at least some of the backwardness of telephone technology in California. "As long as the customer has dial tone, you're fine." Obviously, Pac*Bell was able to convince the fools at the PUC that unless the X-bar was replaced, customers might lose dial tone. After all, the X-bar was installed in 1956 and one might think that 34 years is sufficient service life. But the twenty-year-old ESS? Hell, that's still cooking along just fine. So while the rest of the country has ISDN, CLASS, and you-name-it, we Californians get to pretend that we are in Bulgaria. Excuse me, that's an unfair comparison. The Bulgarians realize it's bad and are trying to do something about it. John Higdon | P. O.

Among the points mentioned about private pay-phones were: 1. The warning about getting charged much higher rates than NJ Bell or United Telephone charges for calls within 201 and what AT&T charges for other calls. 2. The status/legality concerning 10XXX selection. 3. Why private pay phones don't allow incoming calls. Concerning 10XXX selection, one sentence in the article said that where it was possible, there were cases where people could end up making international calls and having it billed to the payphone owner (I wonder if it's because the phone, seeing 10288-0, assumed it was an operator assisted call, instead of looking for 10288-01). Also, even though customers have the right to choose an LD carrier, to the phone owners, having their operator splash you over to an AT&T operator, or having you have the local telco operator do it, is considered sufficient; it doesn't mean they have to explicitly support 10XXX dialing (or pushing). One point raised on both 10XXX and incoming calls is that to the phone owners, the phone is their business, and having to allow either of these types of calls means that their business resource is being used, and they aren't getting any revenue from it. It was implied that if they must support 10XXX from their phones, then they are entitled to share in the revenue from the call.

The point is that the "1+" is an access code, and not part of the phone number. In the US or elsewhere. Actually, when I use my Sprint FON card, a "1+" never plays a role in the dialing: it seems to be "0+"; I don't know about other calling/credit cards. And when I call from a hotel, using whatever rip-off system the hotel has (Yes, I know, but my company will cheerfully pay large phone bills billed to the hotel room, but has trouble with me telling them that I called using my own Sprint card) as often as not, I dial "8+" or some such code, getting me direct access to an LD trunk, from which I dial the area code and phone number. As a matter of fact, as I type this, it occurs to me that in my office, I dial "8" to get a LD dial tone, and then I dial just the area code, no "1+". The point I am trying to make is that what we dial is divided into access codes and phone number, and they are not one and the same. We ought to be clearer about stating what the phone number is when we claim that what we are giving out is the phone number. When I first started using the Internet, I had a terrible time guessing what part of the From: or Reply-to: field was indeed the actual user@node, and what was some sort of routing information the various intermediate mailers had stuck on in an effort to provide me with something that would work, even if much of it turned out to be unnecessary. Again, it may not be worth it to start a thread on it, but I would assert that the "1+" is an access code, and the area code does not include it, and neither does the phone number. ------------------------------ Subject: Re: Boston Gas "Specially-equipped Gas Meter" Date: Sun, 3 Jun 90 21:17:00 CST From: Jim Anderson In article <8329@accuvax.nwu.edu> henry@garp.mit.edu writes: >In the next two weeks, Boston Gas Company will be in your neighborhood >to install a new meter reading system. ... >We will then be able to read your meter accurately by radio signal >from a computer equipped van as we drive down your street. ... >Now, aside from not including very many details of this new system >(does it continuously broadcast use?

I had a tour of E. F. Johnson in Waseca, MN a few weeks ago, and they showed me their product that does this. Apparently, E. F. Johnson is one of the major players in this market. The gentleman giving the tour described how this works. Basically, the meter is built on a SMD style board, with a single large chip, a few peripheral components, an antenna, and a lithium battery. The electronics track usage, and listen on the antenna for a trigger signal. This signal is given by a truck with a transmit/receive antenna. When it hears this signal, it transmits its preprogrammed ID, and the current meter reading, then goes back to standby mode. As far as the signal encoding goes, it probably is a relatively unsophisticated code, as the transmission is only a burst transmission and (my opinion) should only contain the current meter reading, not the usage since the previous reading. I hope this explains how this device works. My understanding is that the electric companies, gas companies, and other utility companies are REAL excited about this meter.

From their DMS exchanges, they managed to block off ALL calls to the exchanges in Stamford which were affected. IE, you would dial 1+977-xxxx or 1+324-xxxx or any Stamford number, and it would be blocked immediately. Depending on where you were calling from, it would either give you a recorded message or a re-order. This would happen INSTANTLY at the exchange you called from, not after taking some time to get down to Stamford. Even 0+xxx-xxxx calls to Stamford were blocked. Is this some new local network feature that SNET and the rest of the Bells have? I recall when the exchange in Brooklyn (NY) (There's a Brooklyn, CT too, so just in case anyone got confused...:-) ) caught fire that all calls were NEVER blocked locally, but only when they got to (or "near") the damaged exchange. The reason I ask is that SNET in many respects is a bit slow to implement new developments in telephone technology. It still has a lot of older Crossbars and Step-By-Steps, like the rest of New England. SNET is just beginning to experiment with CLASS features, but only Call*Block, and only in the Meriden area for at least the next 2 years. Most areas still allow 0+xxx-xxxx calls to be sequenced to AT&T calls (out-of-state), altough they SAY this is supposed to be prohibited. (Although I've noticed that in C&P Tel. territory, mainly Washington DC, this works as well, ie, no difference between AT&T and C&P Tel Calling Card equipment...) Just wondering if SNET has a system to control their calls at the local switches, or did they have someone at each office program it it manually...!?

This is still the case. In fact the BBC is funded entirely by this method (apart from a small income from overseas programme sales {yes, that's how we British spell "program" when it's other that the computer sort}, merchandising and so on). Radio licenses were abolished a long time ago (in the 1950's or 1960's, I think), as they were too difficult and expensive to collect. Television licenses cost (if memory serves) 71 pounds per year for colour, and about 20 pounds for monochrome. There is a derisory discount of 1.25 pounds for blind people on each of these figures. Evasion is widespread, and personally I am deeply cynical about the efficacy or even the existence of detector vans (I've never seen one). I believe the authorities rely largely on non-renewed licences to catch defaulters. The money funds the BBC's two national television channels, including local television opt-outs, *and* all its radio services - 4 national services (5 soon) and numerous local stations. The BBC external services, including the World Service and all the foreign language services, are funded by the government, but are run by the BBC and are editorially impartial (really. It works. Somehow she manages to keep her hands away from it ...). I thought you might be interested in a little more detail.

This turns out to be RCF with no >usage charge. [More good details deleted] Although I personally don't agree with a lot of things that PacBell comes up with, I think their basic decision in this matter was correct. The exact way that they implemented the whole package may cast some doubt as to the underlying motives, however. From both the Telco's and the customer's perspective, the only situation that lends itself well to "grandfathering of numbers" is a conversion from PBX or DID where the customer already has a sufficient number of contiguous numbers to accomodate the Centrex. Creating a Centrex with numbers scattered all over a prefix (or worse, over several prefixs) does EVERYONE a disservice in the long run. It causes an administrative nightmare for Telco and customer alike. I wish I could convince my company that it is bad policy; so far, no cigar. On the other side of the coin, it appears that PB has chosen a method of dealing with the old number that maximizes income rather than customer satisfaction. The system you mentioned should be ONE option for the customer but not the only one. Other options should be made available; if this hasn't been done (have you asked?) then that is most unfortunate. Rest assured that a properly implemented RCF service DOES allow for multiple paths in any variety of electronic switch that is in common use by the BOCs today (1E,1A,5E,DMS,Siemens and I expect others, too). Note, however, that variable call forwarding (the kind you establish and remove yourself) does not offer multiple paths in many of the switches under certain conditions. Also keep in mind that the whole situation should not result in a permanent expense to the company.

A PEP line is easily thousands of baud for a clean line, and | for phone line requirements, the 7.35 or 88.26 number is meaningless. Sorry, you have a slight misunderstanding of the term "baud". The signaling rate in "baud" is defined as "the reciprocal of the smallest signalling interval", that is, the peak number of "symbols" or state changes per second. All of the sub-carriers change at the same time. Thus the PEP protocol is indeed 7 or 88 baud. However, each sub-carrier is only using about (3000 - 300) / 511 = 5.28 Hz of bandwidth. (Pushing a 7 baud signal through a 5 Hz pipe is quite good! The theoretical maximum is 2 baud/Hz: one state for each half-cycle of bandwidth.) Since each sub-carrier encodes 2, 4, or 6 bits per baud, or 14.7, 29.4, or 44.1 bits/second, respectively, at the 7.35 baud rate, that is 2.78, 5.57, or 8.35 bits/second per Hertz of bandwidth. From the Shannon limit: BitsPerSecond < Bandwidth * log2((S/N) + 1) That implies that the signal-to-noise has to be at least: bps/Hertz S/N (dB) > 10 * log(2 - 1) or: S/N > 7.69 dB (min.), for 2 bits/baud (a 14.7 bit/s sub-channel) S/N >16.67 dB (min.), for 4 bits/baud (a 29.4 bit/s sub-channel) S/N >25.12 dB (min.), for 6 bits/baud (a 44.1 bit/s sub-channel) Of course, these are theoretical minima, and don't account for noise to to adjacent sub-channel interference, or loss due to imperfect coding, so the line has to be a good deal better than this. Still, if only 400 channels could get the highest rate, that's still 17,600 bits/second (before subtracting for the 20% CRC and packetizing overhead). In case anyone is still confused, note that sending 6 bits/baud means that you have to be able to send any one of 64 (= 2^6) "symbols" at each state change. Symbols can be encoded as amplitude difference, frequency difference (although not in this case), or phase difference. The PEP scheme, which is actually called DAMQAM or Dynamically Adaptive Multicarrier Quadrature Amplitude Modulation at this level, uses a combination of amplitude and phase modulation on each sub-carrier. Note that if you only used AM, 64 symbols means 64 different voltage levels, which means that (*very* crudely speaking) to avoid error the noise level has to be less than 1/2 the difference between two adjacent levels, so the noise doesn't turn one into the other, or 1/128 the maximum level. Thus, you need a S/N of 20*log(128) or 42 dB. (The "20" is because we are comparing *amplitude*, not *power*, as above.) That this doesn't match the 25 dB "Shannon limit" given above is due to (1) my example was crude indeed, (2) pure AM is not nearly as efficient as QAM, and (3) the Shannon limit -- a *minimum* bound -- assumes that you are employing "perfect" encoding. The actual S/N needed is somewhere between the two, and closer to the upper. Anyway, you get the idea... So the limit to PEP operation is the signal-to-noise of each of a large number of very narrow, slow channels, any of which can be down-graded or dropped from use if needed if *that particular* sub-channel is too noisy. Non-linearities and phase-slopes which would blow away a higher baud-rate modem are shrugged off, since they has much less affect on a 5 Hz (sub)channel. In case anyone's curious about the fact that the quantizing into levels by PCM (T-carrier) puts an upper limit of something like 20*log(128/0.5) = 48 dB on the S/N if 7 bits/sample are being used, note that at 7.35 baud there are 8000 / 7.35 = 1088 samples/baud. A lot of the quantizing noise can thus be averaged out. Rob Warnock, MS-9U/510 rpw3@sgi.com rpw3@pei.com Silicon Graphics, Inc. (415)335-1673 Protocol Engines, Inc. 2011 N.

For the communication equipment we have standardized on cisco TCP/IP routers. Most lines show quite good performance however a few lines have reasonable to high error counts. These error counts are stable and seem independent of network load. With these error statistics we asked our telecommunication people to improve the line quality. Of course they doubted whether the errors were real. Therefore they started with bit-error-rate tests. These tests show that the lines are 'perfect' i.e. no single bit or block error in 24 hours. They used different bit patterns but did not get any error. The next thing we did was to install a PC with a 64K serial interface in parallel to the cisco router on both ends of one 64K link. The program in the PC analyzes the packets and monitors the link. And this is where we really get confused. The PC also finds errors. However these errors are of a different class and different amounts. The link that we monitored has an average of 6000 to 10000 errors per day on one end and a few dozens of errors on the other end. We are now focused on the end with the high error count; according to the cisco the errors are mainly frame errors. The PC reports mainly CRC (or FCS) errors. Can anyone help us getting this sorted out? What is the best way to tackle this problem. Is there any equipment that we can put on the line and realy trust the test results? Has anyone faced such a problem before? Please respond to me directly.

I'm still unimpressed. As most who participate in this forum know, a prerequisite to CLASS is SS#7 between participating offices. Without that, the data required for the handshake necessary for CLASS services cannot be sent. For well over a year now, all Bay Area COs have been speaking SS#7 between switches that are capable of it. Presumably, they want to be ready when the PUC stops picking its teeth.

(Doesn't everyone have to suffer with GTE somewhere nearby?) These COs (all GTD-5) speak MF to each other and to the outside world. No CLASS available here! What this means to a telephone user, CLASS aside, is that a call from a point in Los Gatos to a telephone a few blocks away takes NOTICABLY longer to complete than a call from San Jose to San Francisco, a distance of about 45 miles.

NZ is selling the telco to private investors as part of a privatization program. The gov't hopes to raise at least $1.7 billion (US) from selling the entire company (Telecom Corp. of New Zealand). Telecom was part of the postal service until recently, when it was set up as a separate company. It has 1.5 million telephone lines in NZ, a nation of 3.3 million. The company also provides cellular and LD service and sells telephone equipment. NZ law allows one foreign investor or a consortium of private investors to own up to 49.9% of the telco; the remaining 50.1% will be sold through stock markets in NZ and elsewhere. SW Bell's bid is not yet final; it is working with OTC Ltd., Australia's international LD company, and other entities on possible joint bids. Bids are due June 6; the commission expects to choose a buyer by late June or early July. SW Bell already sells telephone equipment and computerized directory publishing systems in NZ. An SW Bell subsidiary also sells Yellow Pages advertising in five metropolitan areas of Australia. Telecom Corp. of NZ had revenue of $1.24 billion for the year ended Mar 31, '89, with a profit of $168 million and assets of $2.28 billion; it has 17,000 employees.

The CO serves White Rock, New Mexico (505-672), and was installed in 1976 or 1977 (more on this later). White Rock itself is a strange place, in that it has has a population somewhere between 6500 and 7000, which makes it a sizable city by New Mexico standards, yet has no post office and does not appear on most maps of New Mexico. The reason for this is the unique way that Los Alamos County is set up -- the city and county governments are the same, thus the whole county (about 112 square miles) is also an incorporated city, and White Rock is technically just a neighborhood of Los Alamos, even though 10 miles of mesas and canyons separate it from what most people think of as "Los Alamos." Although it is not a distinct governmental entity, White Rock's physical separation warrants its own CO, and LD calls to WR show up as "WHITE ROCK, NM". The local phone company is US West (formerly Mountain Bell). I just got back from a brief trip home, and found out some more odd things about the CO that serves my parents' house (White Rock, New Mexico, 505-672). Ever since they installed the new CO in White Rock (sometime back in 1976 or 1977), it has been the *slowest* switch to disconnect a call that I have ever used. When you're finished talking, hang up the phone and wait *five or ten seconds* before taking the phone off hook or you will never get dial tone. I just learned that my sister uses this slow-disconnect feature to her advantage. If she answers the phone in the family room, and finds out it is a personal call for her and wants to talk in privacy, she can hang up, run into another room, take the phone off hook, and the calling party is still there! Getting a dial tone is also slow. Whenever I use my parents' phone, I have to get used to picking up the receiver, *waiting five seconds or so for dial tone*, and then dialing the number. Kinda hard to break the habit of automatically starting to dial as soon as the phone is off hook, which works on normal CO's that return dial tone almost instantly. I have never used a CO anywhere that is as slow as this. Before the CO was `upgraded' (ha!) I remember getting almost instant dial tone and disconnects. (I think the old CO was an SXS CDO). Despite its slowness, the CO is relatively modern; White Rock was (and is) always one of the first areas in the state to get any new service US West offers (measured service, custom ringing, alternative LD carriers, direct international dialing, etc.) Another strangeness: from every other semi-modern US West CO in NM I have tried, you can get ringback by dialing 59y-xxxx, where y is some digit (usually 3, 4, or 5) and xxxx is the last 4 digits of the phone number. Not in White Rock. Before you ask, my parents are stingy when it comes to phone service, so their line has *no* special features (CLASS, speed dialing, etc.) They also refuse to pay extra for Touch-Tone, and DTMF will not break dial tone. However, pulsing is recognized at high speeds, and most of their phones can be (and are) set to pulse at the fastest rate the phone send out. Back in '76 or '77, I remember the Los Alamos Monitor (the local paper) doing a special article on White Rock's new CO. Mountain Bell was using an experimental new technique called `hot slide in' to install the new hardware, which (I think) entailed activating the new CO, removing the old CO from the building, and sliding the new CO hardware into the building *while it was in use*. I remember something about a compressed air system (like hovercraft) being used to levitate the new hardware so it could be gently moved into place. I believe the article stated White Rock was the first place in Mountain Bell territory (or the country) where this technique was used. From what I have learned by reading this newsgroup and books on telecom, I would guess that White Rock has a No. 2 (or is it 3?) ESS with older, slower hardware than most 2ESS CO's. You do hear clunking sounds as it returns dial tone and as you are connected to a party. Picking up the phone too fast after hanging up from a previous call results in a mostly quiet line with a faint, erratic clicking in the background. Eventually, you get the loud signal that means `you left the phone off hook, dum-dum!'. I could speculate more, but this article is longer than I'd like already and I'd rather turn this over to the net for comments.

Currently, the Bronx and Manhattan share the 212 area code. Approximately 500K Bronx lines and 100K Manhattan cellular/pager lines would be affected. The total number of lines is currently about 2.4 million, divided into 626 exchanges. The maximum number of exchanges in 212-land is 757, and they are being consumed at the rate of 33 per year. The NYPSC will hold public hearings later this year. If the plan is approved, permissive dialing would begin on 1 September, 1992, with use of the new code made mandatory as of 2 January, 1993. Three alternative plans were proposed but rejected as either too costly, too confusing, or too short-term: dividing Manhattan into two NPAs, placing new subscribers in the new NPA without regard to their locations, or moving the Bronx to 718, the area code used by the rest of New York City. cowan@marob.masa.com (aka ...!hombre!marob!cowan) ------------------------------ Date: Tue, 5 Jun 90 15:05 PDT From: Edward_Greenberg@cso.3mail.3com.com Subject: NPA 917 to Serve both Bronx and DID's in Manhattan According to the {Wall Street Journal} (5 June 90, Page A8) NYNEX has filed a plan with the New York State PSC to introduce Area Code 917.

The insert said that all NON-equal access customers, ie, people in older exchanges who could not get equal access, would have all their calls to Northern New Jersey routed over New York Telephone via the "special transit corridor", while those who did have equal access would have their long distance company handle these calls. Later on, during 1987, they started promoting the use of "10NYT", and New Jersey Bell the use of "10NJB". Then, in 1989, New York Telephone sent us a letter claiming to be able to save us money if we make over $50 worth of calls to north Jersey via a long distance company, and switched to NYT. It was sort of a WATS line to north Jersey, but from what I gather they just program the switch to direct all calls to north Jersey made from your phone to use New York Tel instead of AT&T. I'm not sure how this actually works, so if anyone is interested, call NY Tel. I'm sure they'd be glad to talk to you about it! :-) Interestingly, from New York to New Jersey, using 10NYT will only work as a 1+ call. IE, you can call from 212-686 to 201-322 by dialing 10NYT-1-201-322-9950. You can't dial a calling card call this way, however, and must use AT&T for such a call. (And pay a $.80 rather than a $.30 cent surcharge.) Moreover, you can't "sequence call" to New Jersey either, ie, you can't make a call from 212-686 to 212-353 via a calling card, then press the "#" sign to make a new call, and then call New Jersey 201-322. BUT, from New Jersey, you CAN do this. You can make calling card calls anywhere within the north Jersey LATA, as well as to New York City (212/718). Wonder why New York Tel. won't allow this as well ... They could make a lot of money from locations such as Penn Station or the Port Authority Bus terminal, both of which are commuter stops for the heavy trans-Hudson traffic.

Happens all the time here. Whenever the remarkably advanced, super wonderful, all things to all people, greatest thing since sliced bread (but unfortunately discontinued and abandoned by AT&T) GTD-5 switch in Los Gatos crashes (at least once a year) the surrounding Pac*Bell COs are really quick on the uptake. (Probably 'cause they are faced with the problem in Los Gatos so much.) Calls directed to Los Gatos are immediately intercepted by a recording that says, "Due to telephone company difficulty, your call cannot be completed at this time." GTE then usually sends someone up from Thousand Jokes or Santa Monica who is usually able to get things running within a day or two. (Remember, this is the town whose council voted disapproval of GTE as the telco. Silly them, don't they know they have the most advanced CO switching equipment in the world?) Anyway, I feel the wording of the intercept recording is much too charitable. If I were Pac*Bell, the script would be changed somewhat. I leave it as an exercise for the reader to guess what that might be. John Higdon | P. O.

I had said also, and this is a correction to the foregoing article, East and West German postal departments have agreed that it is fully LEGAL to use a West German car or portable phone across the border, simply because the East German telephone network is a DISASTER, and business is almost IMPOSSIBLE if you have to rely on their system. So to encourage the badly needed companies from the western world, they even encourage people to use their wireless home phones in East Berlin. There is no charge for many months now if you wish to take your wireless equipment from West to East Germany. Even CB is allowed, also ham-radio. In that regard, the two Germanies are already united.

I'm afraid they are, and the reason is technical. A DID trunk is actually a phone line in reverse. Your PBX becomes the CO and presents 48 volts back to the telco office. When a call is placed from outside destined for an extension on your PBX, the telco trunk on which the call comes in goes "off hook" or signals the PBX there is a call. Depending on the selected protocol, telco pulses the extension number (or uses DTMF) immediately or after receiving a wink from the PBX. (A wink is momentary supervision.) When the call is answered in the PBX, the battery voltage as presented to the telco CO is reversed, signaling supervision back to the network. Since the whole setup is more or less the opposite of what is the normal arrangement for CO/subscriber connections, there is no way for the PBX to place an outgoing call on these lines.

Is there a >technical reason or is the carrier trying to charge more? It's a technically valid reason. Ordinary trunks use (typically) ground-start signaling, which is a variation on traditional POTS. They send a single pulse plus power ring to initiate ringing, and you just "pick up" (draw current) to answer, and then billing begins. DID trunks are a different kludge. Typically they send a wink (unless they're immediate start, which I wouldn't recomment) and then, when the wink is ack'd by the PBX, they send the digits. No ring, of course. At this stage the connection is already established to the caller, but the charging hasn't begun. Your PBX is not allowed to permit the talk path to open in the line->PBX direction until it sends a supervision pulse which causes charging to begin. (The PBX->line path is open because the PBX, not the CO, sends the ring/busy/etc. tones.) This type of line is designed to be monodirectional; thus DID trunks are one-way only. And in any case tend to cost more than outgoing trunks. (At least they do here!) Note that ISDN signaling does permit DID on two-way trunks, since DID is handled by just an extra information element in the incoming SETUP message, and ISDN inherently handles call supervision.

First of all the assignment itself is different : 1 2 3 4 5 6 7 8 9 0 ABC DEF GHI JKL MN PRS TUV WXY OQ The main difference from the American method is that O is assigned to 0 rather then 6. Also Q is assigned to 0. We too have no Z. The other difference is that all this is ancient history! British Telecom (or the GPO as it was then) changed to "all-figure dialling" in the 1960's. Occasionally I see an old dial with the letters on as described above, but they are now very rare. The letters were used for STD codes (see below), and previously for dialling other exchanges within cities. For example, a number in the Mayfair district of London would be written as MAYfair 1234 - one of the Mayfair exchanges is still 629. I was interested to learn from the "coathanger" posting a while back that the same system was used in the US. Before "all-figure dialling", STD (subscriber trunk dialling, == long distance) codes were alphanumeric - e.g. Blackpool was 0BL3 (all UK STD codes start with zero, as in most parts of the world), whereas Blackburn was 0BL4. Today they are 0253 and 0254 respectively. The trailing digit was used simply to distinguish between codes for towns with similar initial letters, never as a third letter (except by chance). This scheme extends also to the original six large metropolitan districts which were allotted 3-digit STD codes and 7-digit numbers. Apart from London (01 until the recent split into 071/081), the codes are 021 *B*irmingham 031 *E*dinburgh 041 *G*lasgow 051 *L*iverpool 061 *M*anchester This was broken somewhat in the early 1980's by the introduction of 091 for the Newcastle/Sunderland/Durham area in the north-east. Dialling within this area is a real can of worms, but I'll save that for another posting. Because most of the STD codes were assigned back in the 1950's, it follows that, given an unknown STD code, one can make an intelligent guess as to where it is. E.g. I come from an area in the north-west with the code 0706. From the table, it can only be PO, RO or SO (ignoring Q!). In fact the town is called Rochdale. This system is not perfect, but it can help occasionally. It's amazing how much of this stuff comes back to you when you start thinking. All I was going to do was post the letter assignment table. If anybody is actually interested in this STD code stuff, let me know and I'll wrack my brains some more. And I'm just an amateur observer and user of telecom services, with a so-so memory, so there's no guarantee that this stuff is accurate.

Oh, the detector vans do exist - I've seen them, and read about them in the telecom press. But you're also right about using non-renewal records to catch people. This is what happens: They (who *is* they these days? I don't thing it's BT) will target an area of the country where they want to do some enforcement. The detector vans are sent there, and there is a local publicity campaign sometime before the event. The non-renewal records are consulted, and the detector vans are sent by the houses of people who have not renewed. If a television is found operating there, the owner receives a knock on the door. I believe the idea is to scare the excrement out of people by publicizing the enforcement campaign before sending the vans in. I bet it costs more than 71 quid to prosecute someone.

I had an interesting experience with a simpler meter some years ago. The system was a municipal (shorewood Wisconsin) water meter with a repeater outside the house so that the meter reader needed only read the repeater without going into the basement. The repeater failed over a period of years, missing ticks, and finally quit. I was asked to allow the city to replace the repeater. They did, and brought the readings up to date. Later I was billed for about ten years missed water service billings. As I recall, the bill was for more than $200.00. Some discussion with the village manager convinced him that not all of the water had been used this year, and that rates earlier did not include sewer service. We negotiated a price. With gas meters the same alarming thing may happen. What is worse, the numbers will be an order of magnitude larger. Be very wary to see that the REAL meter is read when you purchase a house, not just the repeater, whatever the technological type. | Leonard P.

No, you're completely missing his point: the "1" is INDEED part of every phone number in the US, because the country code for the North American Numbering Plan (US, Canada, much of Caribbean) is "1". This country code is not to be confused with the intra-NANP access code for direct-dialed inter-area-code calls, which also happens to be "1" in most areas of the NANP. (In some, it's the null string, but that will have to change in a few years with the advent of NXX area codes.) But in all direct-dialed calls into the NANP from outside of the NANP, the country code is required. In particular, the string "1" must be dialed after the international access code (which varies from country to country; many countries use "00") and before the area code and local number. So it's certainly valid to state that the ordered pair, say, "+1 802" identifies the area code for Vermont, just as it's correct to note that "+44 71" identifies the area code for inner London.

Before all UK readers fail to renew their TV licenses, I can confirm that TV detector vans do exist - I visited one on display at the East of England show two years ago. The equipment inside looked about 1960 vintage. The operator seemed rather unknowledgeable about the principle of operation, but from what I surmised it is identical to the methods described by Peter Wright in "Spycatcher" for identifying enemy receivers listening to a particular frequency - ie. blip the transmitter frequency and correlate it with secondary emissions on other frequencies. (Note that this distinguishes between a TV being used with a VCR and a TV watching live transmissions - a license used not to be required for the former, although I'm not sure if this is still the case). The TV detector van gets fairly good range information from this source. The antenna can be rotated to give bearing - but it wasn't clear if it could be adjusted to give elevation. The operator is given list of houses in the area which do not have TV licenses from which to start... Even if the equipment does not work, it is often reported that large numbers of TV licenses are suddenly applied for in areas where it is publicized that the vans are operating!

If you (the caller) know the code number which has been set on the phone, you can make the phone go into the speaker phone mode. I believe this same model that I am thinking of will allow the phone to go off-hook into the speaker phone mode if someone at the unit presses a certain button - in other words, the phone will ring once and then answer itself. After your wife heard the first ring, she could wait a second and then say (yell?) Hello! across the room. If your wife does not want the phone to answer itself, she can press that-same-button again to toggle the auto-answer off. In any case, if the caller knows the security code they can make the phone go into the speaker phone (or answerback) mode on this particular Panasonic model. I don't know the Panasonic model number, but it is a fairly small unit (gray in color with an orange speakerphone button) which utilizes a voice chip for the outgoing message and a single micro-cassette for the incoming message and to backup the message on the voice chip in case the power goes out. Most (many?) consumer electronics stores in the Atlanta area carry this particular model for something over $200. I have seen good pricing for it at Service Merchandise and Pace.

If my information is correct, the GTD-5 itself is quite capable of doing SS7 and CLASS. However, the operating company that buys the GTD-5 decides whether or not to make use of its capabilities. Your experimentation has shown, quite convincingly, that GTE has not taken advantage of any of the GTD-5's SS7 capabilities in your area. This is pure speculation, but it may be that the GTE operating company has not worked out any arrangement with Pac*Bell to interconnect the systems with SS7 (perhaps they haven't even *thought* of doing that ??). The question here is who to blame for the conditions you describe. Do you blame the equipment manufacturer or the equipment operator? Ultimately, the telephone service you receive depends most heavily upon the operating company, for it is they who decide what equipment to buy and which of the equipment's capabilities to offer to their customers. I don't feel any compulsion to defend either the GTD-5 or the GTE operating companies, although I am a GTE employee. I know nothing about the commitment of the operating company to provide the service its customers want. All I can do is point out that the latest and greatest switching technology, even if it is in the possession of the operating company, won't do you any good if the operating company chooses not to provide you the service. From a practical point of view, the technology might as well not exist if you are not permitted to use it! If enough customers rag on the telco to provide these neat services, perhaps they will perceive that there is enough demand for the service that it will be provided.

It would not be a simple change and there are some good reasons to keep things separate.

I am looking to buy a new phone for our upstairs, and the best phone to buy would be one that I could just put down on a narrow ledge in the hallway in order for it to be available. I have a cheap, old phone (about nine years old, cost about 10 bucks) called something like a "Mura QuickPhone" there now, and I want to replace it. A more expensive phone would be acceptable, but it would be nice if it did not need some sort of cradle or holder in which to put it. The ledge is narrow, and wide enough for the phone, but an additional piece that did nothing but hold the phone would be a loose pain in the neck that I don't need. ------------------------------ End of TELECOM Digest V10 #417 ******************************   Received: from delta.eecs.nwu.edu by mintaka.lcs.mit.edu id aa12335; 7 Jun 90 4:42 EDT Received: from mailinglists.eecs.nwu.edu by delta.eecs.nwu.edu id aa12191; 7 Jun 90 2:57 CDT Received: from mailinglists.eecs.nwu.edu by delta.eecs.nwu.edu id ab24523; 7 Jun 90 1:53 CDT Date: Thu, 7 Jun 90 1:34:39 CDT From: TELECOM Moderator [To]: telecom@eecs.nwu.edu Subject: TELECOM Digest V10 #418 BCC: Message-ID: <9006070134.ab03928@delta.eecs.nwu.edu> TELECOM Digest Thu, 7 Jun 90 01:34:17 CDT Volume 10 : Issue 418 Inside This Issue: Moderator: Patrick A.

For the last week or two, Wisconsin Bell has been having an odd problem with their system: it's placing calls at random. Only a few people (all in Madison, so far as I know) have been affected so far. They start receiving calls from other phones in the area, as well as through AT&T's long distance network (including international calls). The most interesting thing about this is that these aren't just "misdirected" calls; neither party initiates the call. The phone just rings at both ends. One person in Madison was getting about eighty calls per day through the weekend, including connections to several other Madison numbers, and many international calls (Zaire, China, and New Zealand, for instance). A Wisconsin Bell spokesman said that the company is trying to track down the problem, with the help of AT&T. (Information from several newscasts and the Wisconsin State Journal.)

Herewith, from "Win-Win Negotiating" (1985) by Fred E. Jandt, p.265: Sometimes, hardballers operate on orders from above. For example, it's no secret that you can resolve a complaint much more easily with IBM, whose management practices a win-win philosophy, than with AT&T, where, from the very top down, the propensity is to tell you, "That's our policy." (Translation: "Go drown yourself.") ... "That's our policy" -- those are not only fighting words, they're words of consummate arrogance and defiance. If the person who utters them is working for someone else, forget about rhetoric or other means of persuasion; you've got to go to the boss. And if the person who utters the words *is* the boss, you've got to put a knife to his throat -- figuratively, of course -- and bring him to his knees before you can expect to reason with him. This was five years ago.

There are small parts of Austria which belong to the West German customs territory. These areas have both Austrian and West German area codes (as well as two postal codes).

From north-western Switzerland (the adjacent area) the convenience code for these numbers is 068 xx.yy.zz instead of 0033 89.xx.yy.zz. However, 068 is intercepted in all other parts of Switzerland/Liechtenstein. Convenience-code calls are charged like domestic calls between 50 and 100 km which makes them much cheaper than regular international calls.

I remember The time frame sounds about right. In the local CO which covered the area where I grew up (Morgantown, WV), they replaced a large SxS switch (which took up the whole inside of a brick building) with a new ESS switch. The new switch was much smaller than the old, but there was still no room in the building for the new switch. So they built a separate out-building which was butted up against the old one and installed the new switch in it. They then cut over to the new switch, which was still located outside of the old building, and when they had cleared enough of the old SxS system out, they did a 'hot slide' as you describe, to put the new switch into the old building (after knocking out the wall that separated the two buildings). If I recall correctly, the new switch had long enough cables so that it could indeed be moved on compressed air while in use. - tom internet : mvac23!thomas@udel.edu or thomas%mvac23@udel.edu uucp : {ucbvax,mcvax,psuvax1,uunet}!udel!mvac23!thomas Europe Bitnet: THOMAS1@GRATHUN1 Location: Newark, DE, USA ------------------------------ From: "Donald E.

But I cannot get it to accept any commands. >.....Does anybody have ANY information on this modem? Ian, you've got yourself a pair of a couple of real good "moldy olides" there. MPS48's have been the workhorse of many large, farflung global networks for years. The maker is Racal-Milgo, one of the Big 3 on non-Bell modem makers for years. You can try their factory at Plantation (Ft. Lauderdale subuarb, NOT the Plantation in the Keys), Florida, but they may not be interested in passing out free help. They have a LARGE worldwide service force to sell to you. Better you call around the major banks near you, like Philly and get to someone in the data network area, who get s one or two books for each of the (truly!) HUNDREDS of MPS48s they use in their big machine networks. Here are three things to start you off: 1.) These are four-wire, full-duplex private line modems. That means they work on TWO "two-wire" analog phone circuits, so hook up the "transmit" terminals of one to the "receive" terminals of the other. Those modems can send from across the room to across the ocean on such circuits, so run them wherever you want to...just give them separate "go" and "return" analog circuits. 2.) Such modems in large machine networks are for sync data terminals, and while PC clocks are getting so good nowadays you may be able to just jam async at them and seem to work for a short time, you will probably have trouble with data "slips" on long files unless you run your terminals in "sync" mode and provide interface cables that exchange clock between the terminals and modems. That means more wires in the cables than the usual 3 or so of PC usage. 3.) Such modems transmit a full 0 dBm composite data signal, and expect a received signal of -16 dBm. Their receivers are very sensitive, and can function clear down to about - 42 dBm. In the case of a short wire circuit across the room, or even across the campus, they will probably overload their receivers. You need to either get an attenuator into the analog wire circuit OR reduce the sending level (by means of internal hardware options any tech can readily identify) to - 16 dBm to avoid receiver overload, which occurs very rapidly even at - 12 or -13 dBm received signal level on them. 4.) In big machine networks, the "smarts" are all in the controller, a.k.a. DTE (Data Terminal Equipment). Thus, MPS-48s don't respond to Hayes commands from the keyboard. They're just up on line all the time and transmit whatever you send..if these are the classic "private -dedicated" line version most people have. IF they have two-wire dail-up interface boards added, they expect you to have an external telephone with an "exclusion key" transfer between voice and data, and you dial with the phone, then switch to data connection .. .or perform the equivalent with an electronic substitute. But, I doubt you have that added hard- ware in yours. If you do, the extra boards will be readily identifiable. The MPS-48s are VERY good, durable devices and you should expect good use from them. Some contacting people from large data-using firms and getting a hep technician on them should get them working for you in most any way you like. ...So what do you have? A pair of the "workhorses" from that "other galaxy" of data communications, the galaxy of the big mainframe machines; it seems to be a place dial-up PC users have heard little about, even though it sells a billion or more a year worth of those modems! Once you get a good tech on them, you'll find they are really pretty simple. Happy intergalactic datacomm! ------------------------------ Date: Thu, 7 Jun 90 0:21:34 CDT From: TELECOM Moderator Subject: Crackers, Kapor and Len Rose I have been deliberating holding messages on Kapor and the cracker situation which have arrived this week. Thursday evening there will be at least two special issues devoted to this topic, and I will be picking several messages to include. I was going to have one special issue, and that would have accomodated only a few letters. A second issue will allow me to include a couple lengthy replies. Because the topic is starting to stray far away from telecom and into areas of the law and computer security, etc, this will be the last batch I can print. Several of these items Thursday night will be replies to me, which is the main reason I am running them ... and I won't even be able to include all of them, so heavy is the flow. Late Tuesday night, David Tamkin and I had a chance to speak at length with someone close to the scene involving Len Rose. Some things were off the record, at the request of Mr. Rose's attorney, and I agreed to honor that request. Apparently the Secret Service seized *every single electronic item* in his household -- not just his computers. I am told they even took away a box containing his Army medals, some family pictures, and similar. It is my understanding his attorney has filed a motion in court to force the Secret Service to return at least *some* of his computer equipment, since without any of it, he is unable to work for any of his clients at all without at least one modem and computer. I am told the Secret Service broke down some doors to a storage area in the basement rather than simply have him unlock the area with a key. I am told further that he was advised he could pick up his fax machine (which had been seized, along with boxes and boxes of technical books, etc), but that when he did so, he was instead arrested and held for several hours in the County Jail there. Mr. Rose believes he will be found innocent of charges (rephrased) that he was the 'leader of the Legion of Doom', and that he had broken into 'numerous computers over the years'. I invited Mr. Rose and/or his attorney to issue a detailed statement to the Digest, and promised that upon receipt it would be run promptly. I don't think such a statement will be coming any time soon since his attorney has pretty much ordered him to be silent on the matter until the trial. If the things he says about the Secret Service raid on his home are detirmined to be factual, then combined with complaints of the same nature where Steve Jackson Games is concerned I would have to say it seems to me the Secret Service might have been a bit less zealous. The revelations in the weeks and months ahead should be very interesting. One of the items I will include in the special issues on Thursday night is the report which appeared in the {Baltimore Sun} last weekend. This case seems to get more complicated every day.

Drive to Counter Computer Crime Aims at Invaders Legitimate Users Voice Worries Over Rights By John Markoff From Los Angeles to Atlanta, Federal and state law-enforcement agents have begun an intense battle against computer operators who break into government and business data systems. The agents, under mounting pressure from corporations and lawmakers, say the crackdown is needed to halt a growing threat to commerce, research and national security. But increasingly, civil liberties experts and even some computer industry executives say the crackdown is affecting computer users who are not breaking the law. These experts say such users are being intimidated and are suffering illegal searches and violations of their constitutional guarantees to free speech. Crimes `in the Blink of an Eye' In many ways the computer crackdown parallels the campaign against drugs, with officials responding to an outcry over a serious problem only to confront another outcry over assaults on civil rights. "It's a whole new era," said Stephen McNammee, United States Attorney for Arizona, who has been a central figure in Government efforts to counter computer crime. "Computers are providing a new avenue for criminal activities. It is possible to transmit computer information for an illegal purpose in the blink of an eye." But Representative Don Edwards, a California Democrat, said the authorities had gone too far. "Every time there is a perceived crisis, law-enforcement agencies and legislators overreact, and usually due process and civil liberties suffer," Mr. Edwards said. "The Fourth Amendment provides strict limits on rummaging through people's property." The largest of several investigations under way around the country is a two year old Federal effort called Operation Sun Devil, in which about 40 personal computer systems, including 23,000 data disks, have been siezed from homes and businesses. The siezures, resulting from 28 search warrents in 14 cities, halted the oper- ation of some computer bulletin boards ... little or any of the confiscated equipment has been returned. In all, seven people have been arrested so far. One computer game maker who has not been charged says he is on the verge of going out of business since investigators siezed his equipment. In related inquiries, the Secret Service has surreptitiously eavesdropped on computer bulletin boards and telephone conversations, and in the process agents have entered these networks posing as legitimate users and traded information. In an unrelated investigation of the theft of an important program from Apple Computer Inc. last year, dozens of experts and hobbyists have recently been interrogated by the [FBI]. Civil libertarians and some business executives have begun to organize defenses. Among them is Mitchel D. Kapor, creator of the nation's most popular software program, the Lotus 1-2-3 spreadsheet, who is planning to help finance a legal defense fund of several hundred thousand dollars for some of those accused. Legal Protections Are Unclear Harvey Silverglate, a Massachusetts lawyer and civil rights expert who is working with Mr. Kapor, said, "You have innocent people who are being terrorized as well as investigations of people who have broken the law." He termed the Government actions a "typical American solution: throw your best and brightest in jail." Officials of the Secret Service, which since 1984 has been the primary Federal enforces of computer fraud laws, believe that an alarming number of bright young computer enthusiasts are using computers illegally. "Often," said Gary M. Jenkins, Secret Service assistant director, "a progression of criminal activity occurs which involves telecommunications fraud, unauthorized access to other computers, credit card fraud, and then moves on to other destructive activities like computer viruses." A 1986 Federal law on computer fraud and abuse make it a crime to enter computers or take information from them without authorization. But Mr. Kapor of Lotus said he believe the danger posed by the computer joy riders had been greatly exaggerated. "Now that the Communists aren't our enemies any more, the American psyche has to end up inventing new ones," he said. He and other experts are also alarmed by new investigative techniques that employ computers. The power of advanced machines multiplies the risk of search and seizure violations, these experts say, because they can perform so many simultaneous tasks and absorb and analyze so much information. Moreover, civil liberties advocates say the perils are greater because legal precedents are not clear on how the First Amendment protects speech and the Fourth Amendment protects against searches and seizures in the electronic world. Goverment Surveillance In response to a court-enforceable request under the Freedom of Information Act, the Secret Service has acknowledged that it has monitored computer bulletin boards. In its answer to the request, made by Representative Edwards, the agency said its agents, acting as legitimate users, had secretly monitored communications on computer bulletin boards. The agency also disclosed it had a new Computer Diagnostic Center, in which the data on computer disks siezed in raids is evaluated by machines operating automatically. Civil liberties specialists view such practices as potentially harmful. "Computer mail unrelated to an investigation could be swept up in the Govenment's electronic dragnet if the law is not carefully tailored to a well-defined purpose," said Marc Rotenberg, Washington director for the Computer Professionals for Social Responsibility. The Government's Operations Sun Devil was set up primarily to fight a loose association of several dozen computer hobbyists, including teen-agers, who referred to themselves as the Legion of Doom. Members in various cities stayed in touch through computer networks and bulletin boards and exchanged technical information on how to break into computer systems. In February a Federal grand jury in Chicago indicted two members: Craig Neidorf, 20 years old, and Robert J. Riggs, 21, for exchanging a six-page document describing the operation of the Southern Bell 911 emergency system. Private Document Distributed The indictment, under the 1986 computer fraud law charges that in December, 1988, Mr. Riggs broke into a company computer and stole the document, which the company valued at slightly more than $76,000. He transferred it to Mr. Neidorf by electronic mail on a bulletin board in Lockport, Ill., the indictment said, and Mr. Neidorf later reproduced it in an electronic newsletter. Computer security experts say documents like the 911 description are usually not taken for profit, but rather for the challenge of doing it. Some members of the computer undergournd creat elaborate manuals on how to violate computer security as a sport or hobby. But law-enforcement officials do not see it as a game. Because modern society has come to depend on computers for some much of its government and commercial business, officials view intrusions as threats not only to private property, but also to the very operation of the systems. In another part of the Sun Devil investigation, Secret Service agents in March confiscated computers and other equipment from Steven Jackson Games, a small Austin, Tex., company. Mr. Jackson, the company's president, said the agents were seeking a rule book for a fantasy game that deals with "cyberpunk," the science fiction world where high technology and outlaw society intersect. Mr. Jackson said he still did not know why his company had been searched. He said Secret Service officials had promised three times to return his equipment and software but still had not done so. He said that he had been forced to lay off 8 of his 17 employees and that the company was on the verge of going out of business. "It raises First Amendment questions," said Mr. Jackson. "It's a frightening precedent. I don't think they would have done it to I.B.M." Law-enforcement officials say they have difficulty returning seized computers and software prompty; William J. Cook, an assistant United States Attorney in Chicago, said thorough examination took a long time because of the "levels of information you find in a computer." A Sweep in 14 Cities The largest operation in the Sun Devil investigation came on May 8 when more than 150 Secret Service agents, plus state and local law-enforcement officers, searved the 28 search warrants in 14 cities. In all, seven people, including Mr. Riggs and Mr. Neidorf, have been arrested. In a separate investigation, the F.B.I. has been searching for a year for members of a group that stole basic programming information from Apple Computer and mailed copies to people in the press and the computer industry. The group said it stole the software, which is fundamental to the operation of Macintosh computers, to protest Apple's refusal to let other makers copy the Macintosh. The group calls itself the Nuprometheus League, from the character in Greek mythology who stole fire from the gods. Organizers of an annual West Coast computer meeting known as the Hackers' Conference said at least a dozen of the several hundred people who attended last year's event had reported being recently questioned by F.B.I. agents about the Apple theft. The Hackers' Conference began in 1984 after the publication of the book "Hackers" by Steven Levy, Ahchor/Doubleday, an account of computer industry pioneers at M.I.T. and in Silicon Valley. There is no evidence that the Apple theft was linked to people who attended the Hackers' Conference, and Leo Cunningham, assistant United States Attorney in San Jose, Calif., would not comment on any facet of the case. ------------------------------ Date: Tue, 5 Jun 90 16:43 EDT From: psrc@pegasus.att.com Subject: Update: LOD Woes [Len Rose posted another article to comp.sys.att, which again might be of interest to TELECOM Digest readers.

Here is the article in the Baltimore Sun that is based on a press release from the U.S. Attorney's office in Maryland. -------------------------------- Reprinted from an article in {The Baltimore Sun} MARYLAND MAN INDICTED FOR COMPUTER HACKING by Karen Warmkessel A 31-year old Middletown man,who prosecutors said was part of an illegal computer hackers' group known as the "Legion of Doom" was indicted yesterday for alledgedly helping others break into computer systems throughout the country. In addition to facing federal computer fraud charges, Leonard Rose Jr.,a computer consultant, is charged in an alleged sheme to steal and give out closely guarded software for AT&T Unix computer systems. Breckinridge L. Wilcox, the U.S. attorney for Maryland,said the indictment - the third in a series of related prosecutions of the Legion of Doom - had "far reaching" implications for the security of computer systems in the United States. "The activities of this guy and his group are disturbing" Mr. Wilcox said. He said the investigation, which started in Chicago, and expanded to Georgia, and Maryland, had revealed that Mr. Rose and his confederates gained access to computer systems belonging to federal research centers,educational institutions and private businesses, but he declined to name them. Mr. Wilcox said that because the hackers covered their tracks, authorities had not yet determined whether any harm resulted. "We know what computer systems were accessed," he said. "It may be very difficult, if not impossible, to determine what, if any damage was done. "We don't know if it was done for fun,to see if it could be done, or if it was done form some more malignant motive." One law enforcement source said there were indications that Mr. Rose may have been paid for some programs but that he gave others to his fellow hackers. Mr. Rose, who, according to authorities lives on Willow Tree Drive, and used the name "Terminus," could not be reached for comment last night. He is charged with two counts of computer fraud and three counts of interstate transportation of stolen property. If convicted of all counts, he faces a maximum possible prison sentence of 32 years and a maximum possible fine of $500,000. "He is a fairly sophisticated Unix user who decided to take advantage of that knowledge to work his way into other people's systems" one law enforcement said. The investigation is continuing,and others in Maryland reportedly could be charged. The Unix program, originally developed by AT&T, is an "operating system" that governs the core functions of a computer system. An AT&T spokesman said yesterday that about one million Unix computers are in use in the country, many of them on college campuses. David P. King, an assistant U.S. attorney, said that Mr. Rose not only gave the stolen Unix software to others, but also used it to develop two so called "Trojan horse" computer programs, with seemingly innocuous functions that conceal their true purpose. One of these programs was alledgedly designed to collect "superuser" passwords, which give the user unlimited access to computer systems,including the ability to change the programs and insert new programs.Another program which would have allowed users to use a computer system without authorization. Mr. Rose allegedly used tthe programs himself and gave them to others hackers in Michigan and Chicago. One of the men was a member of the Legion of Doom,according to Mr. King . He said it was unclear where Mr. Rose had obtained the stolen Unix software. There are other federal indictments pending that involve Legion of Doom members in Atlanta and Chicago, Mr. King said. The assistant U.S. attorney said authorities believe that the Legion of Doom is a "small" group of hackers nationally. He said he was unable to estimate their numbers. The indictment alleges that the group used various methods to gain access to computer systems such as masquerading as authorized users, password scanning, and Trojan horse programs. It's members allegedly wanted to break into the system to steal computer software from the companies that owned the programs; to use computer time at no charge; to steal the original text of software and other information; to make telephone calls at no charge; and to obtain and use credit histories of individuals other than themselves, the indictment said. This is the second computer fraud case to be brought by federal prosecutors in Maryland. Mr. Wilcox said the other case was dismissed by a federal judge. [Moderator's Note: W. T. Sykes also forwarded the Len Rose article and the {Baltimore Sun} article. My thanks to him. In the next part of this special issue, several shorter messages pro and con on the whole affair.

I'm currently sysop of a two-bit BBS (not even networked to anything!) and I can say that this is a tough one. For one, how do I "cultivate a responsible class of user"? Is there some way I can tell who is "responsible" and who isn't? Is there some test I can give to determine whether Joe Newuser is a phreak? None that *I* can think of, certainly! Yes, I respond to problem postings. I have quashed budding discussions of piracy; I do *NOT* run a cracker or phreak board on any level that I'm aware of! But I don't read email sent privately between users. It would be possible for me to, of course. It would probably only take 15 minutes a day, given the low amount of traffic I see there. However, I feel that unless I suspect something, I have no right to go through users' private mail. So, let's say that Joe and Jane are model users. They're lively in discussions, and have never made me suspect they're anything but moral, upstanding, law-abiding folks. Suddenly the Secret Service busts in to my apartment and confiscates my system. They show me that Joe sent the dreaded E911 documents to Jane via private email. Why should I be responsible for that? Would you shut down the post office if he had mailed hardcopy to her? For the sake of discussion, let's say that I *am* liable for users' private mail. Should I also scan for crimes other than computer or telecom related? What if Joe tells Jane where she buy some drugs? Am I a dealer if I let that one slide? What if Jane agrees to meet Joe in some hotel in exchange for twenty bucks? Am I now a pimp? I thoroughly disagree with the proposition that a system operator is or should be responsible for the entire content of his system. It seems utterly unreasonable that I should be any more responsible for the content of messages than either the post office is for written mail, or the phone company is for voice. When it comes to that, why should I be more responsible for illegal information on my board than Illinois Bell is? After all, THEY allowed it to be transmitted to me in the first place!

Organization: AT&T Bell Laboratories The signal to noise ratio is becoming intolerable. Let's go back to FACTS and LOGIC. Searches and seizures are authorized by warrants. If anybody believes that the government raids were done without warrants I'm sure we'd all like to hear about it. Whether warrants were obtained should be a verifiable fact. Warrants are issued by judges and are based on evidence. Any information suggesting that warrants were improperly issued or that evidence was fictitious, falsified, illegally obtained, etc. would probably be welcomed in this forum. I think warrants are public information. If we can determine that searches were done with properly issued warrants we would have a situation that would be closer to due process than "abridging of First Amendment rights". Indictments are handed down by grand juries - your peers. Indictments are based on evidence and are customarily (depending on jurisdiction) judgments that the evidence, if not refuted, is sufficient for a reasonable presumption of guilt. INDICTMENTS ALSO SERVE TO PROTECT THE ACCUSED AGAINST FRIVOLOUS PROSECUTIONS. I don't know if all indictments are public or whether the related evidence is public. Somebody should be able to find out. Once you have been indicted you go to trial. The indictment is not a guilty verdict! It's hard for me to conclude that indictment by grand jury constitutes harassment by government. If you don't like the grand jury process or you don't trust your peers to evaluate evidence you've got a more fundamental problem that probably belongs in net.politics. Some postings imply that motive or resulting damage should be a factor in these cases. I think we need to read the law and look at the way the courts apply the law. It's not helpful to argue a case on the basis of what you think the law should be. Perhaps the biggest problem some of you have with the raids, seizures, is that you don't like the law. If that's the case go see your congressman and stop flaming the law enforcement people. The common carrier issue is one of the few lucid topics to surface recently. Indeed, we don't arrest the UPS guy for delivering a package of stolen property and we don't sieze the mail truck when it contains stolen documents being mailed. Is the law weak on this aspect of computer crime? Should sysops be treated as common carriers? Would this solve some problems but create others? I'd be interested in opinions on this.

I could have sworn this was the United States of America. Does "innocent until proven guilty" ring a bell? One of the people nabbed in this federal grabbag was a BBS operator who promptly called the FBI when he discovered stolen information on his BBS. Another case was a game designer who was writing a (non-computer) cyberpunk game. They confiscated all of his equipment because the game instructions were taken literally and one of his employees had been in the "Legion of Doom". But who knows, possibily they are all guilty as hell - but that doesn't make defending them a crime. Why don't we let the courts decide the guilt? I'm more than a little sensitive about this. I run a BBS myself, and given the current legal situation I may have to shut it down. As a BBS operator it would appear that I have absolutely no protection. If people start using my BBS to transport stolen materials then the FBI/SS can break in and confiscate every single piece of computer equipment/software I own. Sure, maybe I'll win in court (although no case I know of has made it that far yet), but I have no desire to wait several years to find out. And just to complete the circle, it would appear that even if I wanted (or had time) to examine what my users were doing, I can't - since that would violate the Electronic Privacy Act. So yes, some of the people Kapor is helping to protect have probably committed crimes. But some of them probably haven't, and the last time I checked this country wasn't supposed to be using the crusade-style justice of "kill them all, let God sort them out". -kee | Alphalpha Software, Inc. | Voice/Fax: 617/646-7703 | Home: 617/641-3805 | | 148 Scituate St. | Smart fax, dial number. | | | Arlington, MA 02174 | Dumb fax, dial number, | BBS: 617/641-3722 | | nazgul@alphalpha.com | wait for ring, press 3. | 300/1200/2400 baud | ------------------------------ From: vaxb.acs.unt.edu!billy@cs.utexas.edu Subject: Legion of Doom Summary Article Available Date: 7 Jun 90 14:46:02 GMT An article summarizing the Legion of Doom incident happenings up to the present has been written by Kevin Mullet, Data Communications Analyst here at the University of North Texas.

RJ11 is a single pair of wires on a six conductor jack. RJ25C is three pairs of wires on a six conductor jack. Under some circumstances you can run RS-232 type sigs on a RJ25C. In fact DEC do I believe, and I have clients that run serial printers and serial terminals on RJ25 set ups. But the price difference between four pair wire and RJ45s and three pair wire and RJ25s is not that much. But it does give you more flexibility. The labor is the same whether you pull three pair cable or twelve pair. But if you don't pull the right cable the first time, it costs much more to do it over. Once stuff is built and furniture is replaced, it takes three times longer to run cable. Do it right the first time. Yes, you can plug a RJ25 type plug into a RJ45 type jack, so you could wire the RJ45s for regular POTs phones and plug 'em in with no problems. Cable is about $40 a kilofoot (1,000 ft), labour is $40.00 per hour minimum and some interconnects want $80.00 per hour to come out and fix stuff. Yup, one less hour of labor buys another 1,000 feet of three pair or twenty jacks. Explain that to the suit dweebs. One way to handle the bean counter types is show them some official looking docs on RJ45 use and say "See, it has to be this way." There are some AT&T docs on sending RS-232 on RJ45Cs and there is a DEC doc on sending RS-232 on RJ25s. I have never seen these docs, but I am told they exist and I doubt they are an urban legend. I do have AT&T "Data Services Reference Handbook", Vols I - V and see no reference there, although there is lotsa stuff on DB-25s. I believe the AT&T 3B2 docs cover RS-232 on an RJ45c. My motto: "Never pull less than six pair". And sometimes I regret not pulling twenty-five pair.

As I understand the situation, an ordinary TV licence is required if a tuner for receiving terrestrial transmissions is present is the system. You do *not* need a licence if you have a tuner-less TV (e.g. a computer monitor with RGB or composite input) hooked up to a tuner-less VCR (e.g. a camcorder or a playback-only model - most recording models have their own tuners) or to a satellite receiver, or of course to a computer.

I don't know how two local exchange carriers such as GTE and Pac*Bell interconnect their systems with Signaling System 7, but when interexchange carriers interconnect with local exchange carriers with SS7, SS7 Network Interconnect is required. One of the purposes of SS7 Network Interconnect is to perform gateway screening between the two signaling networks to control the kinds of SS7 messages one carrier can send into another carrier's network. That's necessary (among other reasons) to allay fears that one carrier could inadvertently bring down someone else's SS7 network. SS7 Network Interconnect trials began in the last half of 1989 and are continuing this year. I'm not directly involved with the SS7 Network Interconnect protocol or its deployment, but the last I heard, it won't be until 1992 that SS7 Network Interconnect is deployed widespread throughout the United States. It could be that GTE in the Bay Area must wait for SS7 Network Interconnect before it can interconnect with Pac*Bell. In the meantime, if they only have three switches in the area to interconnect with SS7, some of the CLASS services won't be very useful. If that is the case, John Higdon may be suffering from the fact that his local carrier only serves a small area surrounded by another carrier, rather from the fact that his local carrier is GTE.

You can encode multiple bits per baud with amplitude and phase shift keying, and in fact every modem above 300 bits per second does so. The only limit here is Shannon's limit - bits/sec < 2*f*log2(S/N) where S is the signal power, N is the noise power, and f is the bandwidth. However, a baud is not a bit.

Caller ID is accomplished by transmitting the calling number in FSK format between the first and second rings. If you pick up on the first ring, the calling number often is lost and will not display. My "box" is about 5 by 3 by 1/2 inches, flat, with a LCD display and cost in the low $60 range. It stores about 60 calls, I think, and dates and time stamps the calls. There are three buttons on the display, scroll forward, scroll back, and delete number. I don't know of any reason you could not use a modem and pc to display the numbers, perhaps associating them with real names. I've heard units with RS-232 output are available. The specification for this service has been published by Bellcore for vendors to use. I've never seen the documents, but they probably have a lot of technical information. I find Caller ID to be useful, but until it is more widely deployed, it will have limitations. For interoffice or interstate use, Signalling System 7 is required to pass the number outside the call path. Another problem is political, the Pennsylvania courts have found this the same as wire taps (I don't agree) and there are strong opinions on both sides of the issue as to whose privacy is invaded.

Believe me, Sprint will recognize a "standard" calling card number just fine. If, having entered such a number after dialing 10333 and the phone number you're calling, you then hear a "Thank you for using AT&T," you'll know you're in trouble.

Actually, BT are kind of doing this now with the London area split. In an exchange with old mechanical directors, when you dialled '0', you would be connected to a register which would first pulse out the code to get you to the outgoing STD center, then just repeat the digits after the '0' to the STD center. With the 071/081 split, this would put an unworkable amount of traffic through the STD centers. What has actually happend is that all director echanges in London have processor controlled directors. (I used to write software for these beasts, but that's another story!) If you dial '0', the director looks at the following digits to see if the call is going to the other London area. If it is, the call is routed over the director area's tandem network, just as if you were calling to your own part of London. Of course if the call is destined to go to another part of the country, it is routed to the outgoing std center just as it always was.

Far as I know, yes. Unlike your home phone (or maybe LIKE your home phone, dunno), BOC pay phones can have a DIFFERENT default LD carrier for 1+ and 0+ calls. Look carefully at the LD company references on the instruction card(s) on that phone. It probably says that 1+ out of LATA toll calls are handled by AT&T and that 0+ out of LATA toll calls are handled by either AT&T or someone else. Far as I know, only one LD company allows (or has facilities for) cash payment for 1+ calls: AT&T. Try dialing 10333-0-700-555-4141 and I'll bet it will thank you for using US Sprint.

I was looking thru the Hello Direct catalog to see if they sold anything like the no-hands speakerphone Darwin Weyh wanted but didn't find any device that would do that, which surprised me; I would think such a unit would be standard equipment for disabled people. At least something with a footswitch or a knee-bump pad or some other no-hands phone answer mechanism, maybe that would be usable by a support-dog or other disabled-helping trained animal. But no luck. Anyway, whilst looking thru the Summer 1990 catalog, on page 25, I noticed two "call control" devices to either retrict toll calls or prevent all outgoing calls with a keyswitch. The former hangs on the wall at the modular jack; the latter seems to be glued to the back of the phone. Both of them appear to use ordinary modular cords; the device has a jack on it, and a short modular cord coming out. On the first, you plug the short cord into the wall socket and plug the phone cord into the device. On the other, you stick the keyswitch block on the back of your phone, plug the short cord into the phone's jack, and the phone cord into the box. What stops people from simply unplugging the modular cords from these control devices and bypassing them by plugging the phone cord direct into the wall jack or into the telephone, respectively? Am I missing something? This appears trivial to bypass. If they had the security "TelCord-Lok" connectors shown on page 38, at least this unplugging and replugging would be difficult, but they don't. By the way, does anyone out there use these "TelCord-Lok" screw-secured modular plugs? The catalog illustration carefully avoids showing just what kind of a screw they use, and they ask $10 for the "special tool" to connect/disconnect these plugs, but it sort of looks like a male Torx-type head screw in the side view they show. Is that what it is? I think an ordinary socket-type nutdriver would work on it, if so. Needle-nose pliers should do it in any case ... And a scissors cuts the cord. :-) Regards, Will wmartin@st-louis-emh2.army.mil OR wmartin@stl-06sima.army.mil ------------------------------ Subject: Is Analog Cellular Dead? Reply-To: John Higdon Organization: Green Hills and Cows Date: 7 Jun 90 17:30:14 PDT (Thu) From: John Higdon While shopping today in a local electronics emporium, the new Motorola handhelds caught my eye. My venerable GE Mini is pushing three years old now and is definitely dated. These Motorolas looked pretty neat and could be carried much more easily than the old GE. As I started to attract the attention of a salestype, the sinking feeling hit. With the rush to develop digital cellular, buying any currently available cellular radio would be a major mistake. The question concerning its obsolescence is not "if" but "how soon?" The cellular industry may be shooting itself in the foot. Just when roaming agreements and other standardizations are beginning to make mobile telephone service worthwhile, digital promises to undo all of that. In an area such as LA, where digital will undoubtedly appear early on, a customer could buy a radio that would be virtually useless elsewhere (such as the Bay Area, where digital will be much slower in coming.) Or else we will have the standard electronics industry fix: make the customer carry around a bulky "multi-lingual" radio until the manufacturers and service providers decide just what they are going to do and when they are going to do it. Frankly, I am so put off by this sudden about face ("suddenly we can't do without digital") that I may just keep my GE Mini until there is no more analog service, and then just do without. I hope other cellular users vote with their pocketbooks as well. John Higdon | P. O.

Below are some excerpts from a news article in the Wilmington (Delaware) {News-Journal} of 9 June 90 under the title, "'Dropout' Computer Hacker Sentenced to Finish School." ``A 16-year-old eighth-grade dropout, who was part of a computer-hacking network that used pirated credit information to make purchases will return to school by court order. The Glascow-area youth was sentenced Thursday in Family Court on theft and computer-misuse charges for his part in a ring that included teens in Michigan and California, New Castle County police said. In addition to requiring the boy to complete school, the court placed him on probation until he turns 18 and ordered him to pay $3,049 in restitution and $1,018 to the state victims' compensation fund. The court suspended a $6,790 fine.'' [The boy was arrested in May for receiving goods which were purchased on credit card numbers which were stolen. The News-Journal does not publish names of youths who do not commit violent crimes, so his name does not appear in the article. Apparently the boy used several rouses to get people to give him their credit card numbers over the phone. He then traded some of those numbers with a Michigan youth in exchange for access codes and numbers to a national credit bureau, and used those systems to get more numbers in his local area. He then charged purchases to those numbers and had them deliver to an empty apartment which he arranged to be at. Some of the other activities he was involved with include:] ``* Using the [illegally obtained credit card numbers] to order computer equipment and have it delivered to vacant homes. He also rented a limousine and charged the fee to the card. * Trading some of the pirated information for computer software from hackers in Europe. * Tapping into an '800' number and using it to make numerous long-distance calls. * Giving credit-card numbers to a Los Angeles teen, who [used the information to also defraud the credit card companies].

We have a modem and a fax, and a Novell network. We started out with two telephone lines and ordinary telephones. Needless to say, we quickly bought a telephone switch. The manufacturer is a Japanese firm named Kanda. It had five lines and a maximum of sixteen extensions. It turned out not to be a wise choice -- after a while you get a craving for all sorts of advanced features; this switch did not supply them and it has no expansion capabilites. Right now we have four lines connected to it, the fifth line is run throughout the building and connected to ordinary phone sockets. If someone wants modem access, he has to get the modem (physically) and plug it in. Same thing holds for the answering machine. So much for flaming. Here comes the question: Has anyone seen a telephone switch which has the following features: o Cheap... < 5000$ (Why not?

Date: Fri, 8 Jun 90 18:20:48 GMT My company is replacing a fifteen year old six button Comkey system because it is maxed out on lines. Our primary requirements are reliability and longevity. We need eight lines and sixteen stations now and don't anticipate explosive growth. Both the AT&T Spirit and Northern Telecom Norstar Meridian systems meet our needs on paper. I know that the Spirit isn't fully digital and the Meridian is; but they are comparably priced - the Merlin II while digital is more importantly substantially more money and has more expansion capacity than I think we'll need in the next several years. My company doesn't (yet) require the all the bells and whistles on either system. But given that our last phone system was used for fifteen years a secondary goal is a system that will allow us to take advantage of new features as they become available locally. I don't expect ISDN in our area for some time despite assurances otherwise. I would like to hear from people who have experience with either system - what are your likes and dislikes in how the system operates? What is your opinion of reliability and service responsiveness? How about voice quality? Ease of use? etc, etc?

I guess Heisenberg limits that | somewhere, but not for a long time. Please read what I said again: the theoretical limit is 2 *BAUD*/Hz (the Nyquist limit), not two bits/Hz. And since Hertz == cycles per second, your next statement, "you could shift each half cycle", confirms this. "Baud" == "symbols/second" == "state changes/second". So if one changes something on each half-cycle, that *is* 2 Baud/Hz, just as I said. Now what you really seem to be talking about when you say "by as fine an increment as you could measure" is how many states you can differentiate from each other, or how big your symbol alphabet is. And the limit there is not Heisenberg, particularly, but Shannon. The channel (or system) noise which is added to the signal puts an upper limit on how many states you can distinguish. Whatever the method of modulation -- phase, amplitude, frequency -- at some point in the receiver you will eventually need to decide which of your finite set of states (symbols) to assign to the actual current analog value of the received signal. The circuit for this is an analog-to-digital converter (A/D), also called a quantizer or "slicer". For each signaling interval (the length of which is 1/Baud_rate) you will get one digitized sample which purports to name which symbol was sent during that interval. How many bits it takes to name all the states is how many bits per symbol you have. And bits per symbol times Baud rate is bits per second. So *of course* if your phase discriminators (A/D's) are perfect, and there is zero noise, you can discriminate as many distinct states as you like, and send as many bits per symbol as you like, and therefore as many bits-per-second per Hertz of bandwidth. But real channels have noise -- they are *not* perfect, thus your measurements will not be, either. And the theoretical limit to how many different phases (or whatever) you can use effectively is just the Shannon limit: C = W * log2(SNR + 1) [Page 26 in reference given below] The fundamental "channel capacity" C -- the upper limit on the number of bits per second you can push through a channel with an error rate "as low as you like" assuming you use a coding scheme that is "good enough" -- is the bandwidth "W" in Hertz times the logarithm base-2 of the signal-to-noise ratio SNR -- the *power* ratio (energy per time or energy per bit) -- plus one. The Nyquist theorem says that with perfect A/D's [which we actually can come quite close to these days, at least as far as voice-grade modems care] we can get all the information from a band-limited signal by sampling at a Baud rate B = 2 * W (which is the same as your "each half cycle", above), so if you send R bits/symbol we can equate C = R * B, which gives: C = R * B = (B/2) * log2 (SNR + 1) Simplifying, the maximum useful bits/symbol is: R = log2(SNR + 1) / 2 [Page 40 in reference given below] This says if you have a signal/noise power ratio of 255 = 24.1dB (which is a *voltage* ratio of just under 16), and you have a perfect modulation/demodulation method and a perfect [actually, good enough] error-correcting coding scheme, you can send 4 bits/symbol or 8 bps/Hz of bandwidth. [For those who care about such details, this is ~15 dB "Eb/N0", that is, energy per bit divided by noise power density per Hertz.] But in practice, modulation methods such as phase-shift modulation (PSK) are *not* ideal, they "waste information". I don't have tables for 16 bps/Hz, but I have a chart for coherent PSK that goes up to 10 bps/Hz [Ref: Fig 1.7]. In order to achieve a bit error rate of 1 in 10**5 (no error-correction code), you need the following SNRs (plus or minus a few tenths of a dB for my chart-reading error): Overall Shannon # of phases bits/symbol bps/Hz Eb/N0 (dB) SNR (dB) Limit (dB) 2 (0/180 deg) 1 2 9.5 9.5 0.0 4 (0/90/180/270) 2 4 10.0 13.0 4.8 8 (0/45/90/...) 3 6 14.0 18.8 8.5 16 (0/22.5/45...) 4 8 18.8 24.8 11.8 32 (0/11.25/...) 5 10 23.8 30.8 14.9 As you can see, multi-phase coherent PSK is roughly 10dB worse than the Shannon limit, and is worse off at the higher bits/symbol end (although asymptotically is within a constant factor of the Shannon limit [Ref: p.41]). The best way to use PSK seems to be with four phases, where the excess loss is "only" 8.2dB, which is probably why this version (a.k.a. QPSK) is quite popular in modems. Most higher bit-rate modems use a combination of amplitude and phase modulation (often called "QAM" whether or not the phase-modulation is really "quadrature"), which gives better performance than either AM or PSK alone. [Reference: Michelson & Levesque, "Error-Control Techniques For Digital Communication" (Wiley-Interscience 1985), pp.26-41. Since Figure 1.7 actually graphed Eb/N0 versus PsubM, the *symbol* error rate, I had to extrapolate all the curves (except M=2) down below the chart to get an Eb/N0 corresponding to a 1.0e-5 *bit* error rate. This is the source of much of the "chart-reading error" mentioned above.] In article <8772@accuvax.nwu.edu> codex!peterd@uunet.uu.net (Peter Desnoyers) writes: | However, a baud is not a bit.

Oops! You fell in the trap, too! Those 9600 b/s modems use 4 bit/symbol modulation, and so actually run at 2400 baud. And 2400 baud on 2700 Hz (3000 - 300) is not as good as 7 baud on 5 Hz. On clean lines the Telebit will run 6 bits/symbol, so at 7.35 baud that's 44.1 bits/sec in 5 Hz, or 8.8 bps/Hz. 9600/2700 is a mere 3.6 bps/Hz.

The theoretical maximum is: max bit rate = bandwidth x log(2)(1 + S/N) where S/N is the signal to noise ratio log(2) is log base 2 (not 0.30103 :-)) For example, using a normal telephone line with a 3 kHz bandwidth and a 60 dB (1000:1 for the formula) S/N ratio, you can in theory transmit 30,000 bits/sec. You can use phase, frequency, or amplitude modulation. The maximum bit rate is reached when you can no longer resolve the signal variation due to noise.

Not really. Those 7 bauds at 6 bits per baud come to 42 bps over 5 Hz. The highest rate I've heard of over the 3000 Hz band using PEP is something like 24000 bps, or about 2.5 times as much as V.32. 18000 bps is not terribly uncommon. `-_-' Peter da Silva. +1 713 274 5180.

Here at Apple Computer we run six RJ-45's to each and every cube. We don't run eight wires to every jack though, only four.

Be advised that most twisted-pair Ethernet and all ISDN basic rate interface lines I know of require an RJ-45 jack even though they don't use all eight wires.

A "New" Thread In Volume 10: Issue 419 Paul Flynn discussed some of the limitations on CLASS (I think CLASS is a Registered Service Mark, or some such, of Bellcore.) services due to the current lack of SS7 interconnectivity between carriers. This reminded me of a similar issue I have been meaning to mention: Calling Line ID (CLID, "ANI", etc) is, as currently implemented under the CLASS specifications (there are other extent ways to do it), an SS7 based feature insofar as it operates between switches. Since interexchange carriers (IXCs) don't currently connect to the local exchange carriers (LECs) via SS7 to any significant degree, CLID is not available on inter-LATA calls. Thus, I can't use it to differentiate my mother calling me from the, more usual, boiler room call. Thus, it is not worth much to me, nor, I suspect, to a fair number of potential customers. Of course, the people touting CLID are aware of this limitation and are trying to remedy it by arranging for ANI spill from the IXCs. Current trunking arrangements spill ANI from the LEC to the IXC, but not vice-versa. The LECs would like to convert their incoming IXC trunks to deliver ANI. This could be done via SS7 interconnectivity, but I doubt that SS7 is required. Sound simple? Au contraire: It appears that the IXCs are more than willing to provide the information, but at a price. I guess the reasoning is that the LEC wants the calling number information in order to sell it, so the provider, the IXC, should be paid also. The LECs seem to argue that what is good for the goose is good for the gander. They provide ANI to the IXC at "no" charge (ANI spill is included in the tariff for the current interconnect trunks), so they should get it from them for free also. Of course, the IXCs need the info for billing, but they also sell it to some of their customers. It is beginning to look like this may develop into an amusing little brouhaha. There have already been some positions put forward at some of the standards meetings that appear subtly linked to this issue. At any rate, its outcome should have some interesting implications. For example, if the IXC is entitled to payment for the information, by parity of reasoning, isn't the calling party entitled to compensation also? One, if one were an LEC, might argue that the calling party is compensated in lower rates, but with price cap regulation that is a harder case to make with a straight face. #include disclaimer.standard * John McHarry (703)883-6100 McHarry@MITRE.ORG * ------------------------------ Subject: Telephonic Regression Reply-To: John Higdon Organization: Green Hills and Cows Date: 8 Jun 90 10:58:49 PDT (Fri) From: John Higdon In the spirit of government over-zealousness, how many have noticed (at least in California) the latest media attention to the role of telephony in the matter of drug sales? It would appear that drug warriors have just discovered that many drug deals are consumated with the assistance of public telephones, pagers, and cellular equipment. According to some of the stories (including a mention in this forum), a number of the utility pay phones have been replaced with old rotary dial models (so that pagers can't be activated) and some merged subset of these phones have also been disabled from receiving calls. In the Bay Area, there has even been talk about removing some pay phones altogether, although Pac*Bell spokespeople have pointed out that should be considered a last resort option. So it appears that in the name of the War On Drugs, telephone service is to be denied to a certain subclass of people. Disabling the TT pad after the call is dialed (or installing rotary phones) eliminates the use of many services, not just pagers. What we are in effect saying to people who live and work in certain (arbitrarily selected) areas is, "You are not entitled to have the convenience or utility afforded to those in more upscale places." Not that drug use or trading doesn't occur in Willow Glen (as an example), it's just that more money makes possible a more sophisticated and covert methodology that isn't obvious to residents or police. Saying to people whose only telephone service might just be a public telephone that they will have to do with less because of a current hysteria is highly offensive. But I feel that more is on the way. In the California legislature is a bill under consideration that would make it a crime for anyone under the age of 18 to have a pager (Dougie Howser--watch out!). I predict that in the forseeable future, legislation will be considered that will require ALL users of pagers and cellular phones to register with the state attorney general's office, stating the use and purpose of the equipment. No registration, no service. It is sad that while we are seeing great advancements in both the utility and convenience of telecommunications, congresscritters (and others who depend upon re-election for their fat pay checks) feel the need to artificially restrict citizens' use of technology in the cause of "crowd pleasing". Do they really think that if you take away pagers and pay phones that the "drug problem" will go away? John Higdon | P. O. Box 7648 | +1 408 723 1395 john@zygot.ati.com | San Jose, CA 95150 | M o o ! [Moderator's Note: The Chicago City Council is now on this same tangent, thinking somehow that if Illinois Bell eliminates pay phones in the housing projects (or makes them one-way outgoing, or removes the touch-tone or some combination thereof), that the drug traffic will slow down. Of course, the fact that these steps would be all the more oppressive to people who live in Housing Authority properties and are too poor to have a phone of their own and must rely on the single outdoor (frequently out-of-order) payphone in front of the combination liquor store / state lottery agent on the corner is never considered. PT] ------------------------------ Date: Sat, 9 Jun 90 11:55:11 EDT From: Thomas Lapp Subject: Diamond State Telephone to Offer Meter Reading Service There was recently discussion over reading utility meters either by radio or via telephone. A news article in the Saturday, 9 June 90 issue of the Wilmington (Delaware) {News-Journal} indicates that Diamond State Telephone is presently seeking approval to offer meter reading services to utilities in its area. The system is the same as has been discussed in these pages before: the company calls your home with a method that does not ring your phone, and the unit attached to the meter and phone line sends the data requested. As in the other system, if someone picks up the line while the data transfer is going on, it is cancelled and the user has access to his phone line. The data request call is tried again later. Some interesting points from this article that I had not seen in prior postings: "...the utility's computer sends its customers' telephone numbers into the automatic meter-reading equipment, which in turn dials the customer using a special line so the subscriber's phone doesn't ring..." "...A call takes only seconds and will be made between midnight and 6am,when calling volume is lightest, said [Douglas R.] Smith [manager of regulartory matters for Diamond State]..." "...Water companies have been the first to take advantage of the service ...but in the future, all metered utilities -- electricity, gas and water -- could be hooked into the same system ... if all the utilities work together...." "...The system is working in New Jersey and in the trial stage in Pennsylvania ... Hackensack Water Company is its [New Jersey Bell's] largest customer with 170,000 meters attached to the service. Four other water companies are in the process of adopting the system..." "...According to the application filed with the PSC, utilites would pay a non-recurring charge of $1,500 for the central office special access circuit, a monthly rate of $410, plus 3 cents a call in off-peak hours..." Two quick comments: I'm assuming that the "special access circuit" between the utility and the central office would be a dedicated line. I'd hate to think that it would be a switched circuit. There probably isn't a whole lot of info you could get from 'cracking' a utility reading system, but if you take that datum with all the others you can get on a residence, it might pose a security risk. I know, rather far-fetched, though. The other thing is a little less serious. If the utilities are charged a non-recurring fee of $1,500, does this appear on their third bill? And does it continue to appear on other bills even when they tell the phone company to remove the "extra non-recurring charges?" ;-) - tom internet : mvac23!thomas@udel.edu or thomas%mvac23@udel.edu uucp : {ucbvax,mcvax,psuvax1,uunet}!udel!mvac23!thomas Europe Bitnet: THOMAS1@GRATHUN1 Location: Newark, DE, USA ------------------------------ Date: Sat, 9 Jun 90 12:48:13 -0400 From: Henry Mensch Subject: Re: Cracker/Phreaker Crackdown Reply-To: henry@garp.mit.edu In reply to Frank Earl's note ...

"A routine review of your AT&T account indicates that you are currently being charged standard prices for your out-of-state, direct-dialed AT&T Long Distance calls, and that you make the majority of these calls to area code (717) in Pennsylvania." "To benefit from this new plan you would need to increase your AT&T Long Distance calling to your selected area code by about 10 minutes per month." On the basis of my bills, they decided that I would want to get a special rate to area code 717 (.12/min evening/night/weekend, .20/min day) plus 5% savings on all other out-of-state direct calls, for only $1.90 a month. (There are 3 calling rates based on distance. From 817 (Fort Worth, Texas), I think everything is "medium" except Alaska, Hawaii, Puerto Rico and the Virgin Islands. The $1.90/month seems to be fixed.) Hmmm, how did they choose this? Well, if they know I have two lines billed on the same bill, since January, 1989 that was one evening-rate 717 25-minute call in December, 1989, and one evening 717 29-minute call in February, 1990. If they don't know about the second line, then they only know about the first call. If they went back much further than November, 1989, they would have seen that night-rate 614 calls dominate the out-of-state bill in 1989. Now, if I had gotten this plan in December, 1989 (on ONE line, and made all the calls on that line), and made 1 10-minute evening-rate call each month in addition to actual use, I would have paid $11.40 in SelectSaver bills to date to save about $4.56 on calls, for a net loss of $6.84. And they are strongly implying that they LOOKED at my bills and decided I could save money. AAARRRRGGGGGGGHHHHHH!!!!!!! If they want me to save money, the same plan applied to area code 214 (Dallas, which is in-state, adjacent, and intra-LATA, because unless you use 10288, Southwestern Bell handles it and bills at a higher rate than AT&T) might work, since I call there a lot more. I wonder if AT&T wants the FCC to know you even CAN dial from 817 to 214 via AT&T. One interesting feature: they say NOTHING about changing my long-distance carrier (my default carrier is null) or having to have it be AT&T. Gordon L.

Fear not, good gentle. There is is HUGE base of people out there who have analog phones. Cellular operators can't expect them all to buy new phones overnight. They'll start by installing a few digital channels and gradually phasing out the analog. I suspect that you'll still be able to get an analog channel anywhere you go for many, many years. >Or else we will have the standard electronics industry fix: make the >customer carry around a bulky "multi-lingual" radio until the >manufacturers and service providers decide just what they are going to >do and when they are going to do it. Give that man a cee-gar! I suspect that in the near future you'll have your choice of buying a pure-analog, a pure-digital, or a hybrid mobile. With the mixture of analog and digital channels available the hybrid shouldn't be strictly necessary, but it has the advantage of pure-digital in that you can enjoy the benefits of digital where that's available and still be able to use it in service areas that haven't upgraded yet. (Yes, I know that the "benefits" of digital from the user perspective are debatable. Let's not open that up again, eh?) You sound like you don't like this idea. Can you suggest an alternative? As I see it, a gradual phase-in is very much preferable to an overnight switch to the new technology. >Frankly, I am so put off by this sudden about face ("suddenly we can't >do without digital") that I may just keep my GE Mini until there is no >more analog service, and then just do without. I hope other cellular >users vote with their pocketbooks as well. Why the hostility here? No one will be forcing you to go to digital, at least not for a very long time. As I said, I don't think the operating companies can afford to blow off the huge installed base of analog customers. The main purpose of digital (as I see it, anyway; yes, I am involved with cellular, but only tangentially with digital) is to squeeze some extra channels out of a limited amount of bandwidth. A purely digital system has three times the number of channels that an analog system does. THAT'S why we "suddenly can't do without digital". The airwaves are getting full!

Of course, he will use >only one at a time. The telco won't set this up for him. This really isn't technically possible. Even if he promises to never turn power on to both of them at the same time, accidents do happen. If power were on to both units at the same time, both units would respond to commands from the cells, and bad things would happen, which would generate trouble reports and possibly disturb other calls in the system due to co-channel interference. Although a single ESN may have an infinite number of telephone numbers, each telephone number can have at most one ESN. This is an immutable part of the design of the AMPS system. Although the moderator suggests that the way around this would be to convince the cellular carrier to not do its usual serial number check as part of handling his calls, this has all the problems mentioned above, plus the problem of making the roamer validation system not work. Mr. Cantor would be subject to fraud from anyone anywhere in the U.S. or Canada who knew that his phone number had no ESN. The only option is to have a portable which is carried from car to car. Some portables, especially NEC and Motorola portables, are designed such that you can install a complete set of 3 watt electronics in each car which are activated only when the portable, which contains the number and ESN, are plugged into the socket in the car. This way, someone who drives two cars can have a single phone number for each car. Or, better yet, two people who share two cars can each have their own portable and their own number will always be active in the car they are driving. /john [Moderator's Note: Actually, Mr. Covert's suggestion, re use of portables, makes a lot of sense. There are so many varieties now, and the price has come down so much, it seems far more efficient to simply transfer a hand-held unit from one vehicle to another ... and carry it when you leave the vehicle, as I do. A couple portable units, combined with call-forwarding as needed should be adequate.

It looks like the survey was flawed, due to an error in the way I set it up. There have been several messages which pointed out that unless I was aware of the dietary and banking habits of the readers, it would be impossible to accurately give any meaning to the results. To avoid embarassment or possible legal ramifications, readers were asked to answer one set of questions or another set, based on the flip of a coin. The two question sets were: 1) 1. Have you made one or more phraud calls in the past six months? 2. Have you broken into a computer or gained unlawful access to a computer in the past six months? 2) 1. Have you eaten a hamburger for lunch in the past two weeks? 2. Have you gone inside the bank you usually do business with in the past two weeks? We know that as the number of coin tosses increases, the likelyhood is that there will be an even number of heads/tails come up. So, we can take the number of answers received, *assume that half were answering the relevant questions and disgard half the results, evenly from all possible answer groups*, getting some idea of how many of you are naughty, and how many are nice. But several of you wrote to point out that without knowing if a preponderance of the readers here were vegetarians, or misers who did not trust banks, the results would be difficult or impossible to interpret. If no one eats hamburgers or visits banks, then a large number of 'no-no' answers would appear. And, this is in fact what happened when the results were tallied -- more on this later. A better way of handling the survey, aiming for the highest possible number of accurate answers while still allowing a relative anomynity in posting would have been to ask but the first set of questions -- the relevant ones -- with the condition that if the coin toss was heads, answer the questions accurately. If the coin toss was tails, then flip the coin twice more: (1) heads/tails = yes/no on phraud calls; then (2) heads/tails = yes/no on computer cracking. In either event, do not reveal the coin toss -- simply send along your answers. Here are the results from the first time, although flawed. They are presented for your amusement, and I hope you will answer the survey a second time, using the more accurate collection techniques. Total respondents: 636 36 (5.7%) answered yes to both cracking and phreaking in the recent past. 78 (12.3%) answered no to phreaking and yes to cracking. 66 (10.4%) answered yes to phreaking and no to cracking. 456 (71.7%) answered no to both questions. No cracking or phreaking. Percentages slightly over 100% due to rounding. Of course, if we assume half the respondents were talking about their lunch and financial matters, then the figures would decrease, but the percentages would stay the same. Still, as pointed out above, the results are suspect, so let's do it over again: Flip a coin. Heads, answer these questions honestly. 1) Have you made one or more phraud phone calls in the past six months? 2) Have you broken into a computer or gained unlawful access to someone else's account in the past six months? If tails, flip the coin twice more: On the first flip, answer the first question: heads = yes / tails = no. On the second flip, answer the second question: heads = yes / tails = no. Then, mail your results, with the subject header 'survey' to: telecom-request@eecs.nwu.edu Your answers should take one of these forms: 1) Yes Yes 2) Yes No 3) No Yes 4) No No Avoid the header 'questions' since some late responses to the first survey are using this header. Do not reveal the coin toss(es) and do not make other comments for which a reply is expected. Results to this hopefully more accurate version will appear in a couple weeks.

We did this in 1978 as part of the Deafnet project (PDP-11, V6.5 Unix, Arpanet host #2, Vadic rack/dialer with custom 103/W modems). It was indeed very useful, but the dialout capability was restricted to project staff (as opposed to normal users) since we had no easy way of connecting the resulting bills with specific individuals, or recovering the costs thereof. The telco would have to provide billing info in some machine-readable form before a third party could operate such a service. Given that, a commercial value-added-net (VAN) like Tymnet/Telenet could certainly install relays if they wanted to. So could the telco itself for that matter, although you'd be paying by connect time rather than amount of data.

I too was given the 'opportunity' to save on my long distance calling via an AT&T plan (I believe it was the "Reach Out America" plan). I reviewed my phone bills for the previous six months, and found that based on their plan, I would also come out slightly behind unless I raised the amount of time I spent on long distance minutes/month. I wouldn't have paid much more in absolute dollars, but the percentage increase was about 20%. Plus, it would have induced me to make more LD calls in the future to take advantage of the plan. I feel that it is just a clever marketting ploy on the part of AT&T. I think they arrived at their rate structure by analyzing several hundred thousand billings, selecting those that fall into the range of a couple of hours per month, and then devise a plan where they can drop the effective hourly rate but still make more due to service charges, etc. Plus, they would also have the benefit that the plan would induce subscribers to who otherwise wouldn't have to spend more time on the LD calls to justify the cost of the service. It sounded like a good way to go broke saving money. In the end, I followed Nancy Reagan's advice and just said 'No'. Later in time, I again looked at my bills for the three months following the period I would have started if I had selected the plan. I found that my cost would have been even higher (percentage-wise) because I made less calls than the previous six months which triggered the solicitation. I think I made the right choice. -dave ------------------------------ From: "Marc T.

I'm curious: in what way are they weak and unreliable? I have owned five Panasonic cordless phones in the past ten years or so and have found them to be entirely satisfactory. All of them are still in service (though not necessarily by me). The two that I am still in possession of are KX-T3900s. One of them has really been beat to sh*t: dropped, stepped on, inadvertantly thrown across the room (not because I was mad at it but it rang when I was asleep and I woke up violently), dropped in the full sink, and dropped in the toilet. It works as well as the day it was purchased, a little over a year ago. How well does it work? Its audio quality is a shade inferior to an AT&T 5500 that I also own, but has considerably more range. Standing next to the base units the AT&T beats the Panasonic. But get about twenty feet away and the AT&T starts deteriorating and at about 40 feet the Panasonic (whose audio quality seems to remain more constant with increasing distance) surpasses the AT&T in audio quality.

Some TDDs do have a "memory" option that allows users to store fairly short messages (2000 chars or so) and send the text in a burst (at 6 or 30 cps, depending). I doubt anyone knows whether this feature is actually used much; I myself don't, but I probably type faster than most people. Instead of saying whether this is a good idea or not, let me just turn the question around. Why don't all you hearies invest a little money in something to store your voice and play it back at high speed? I believe there are commercial devices for high-speed intelligible playback, which some blind people use to maximize their information input. Or even better, add a compression encoder so that whenever you call someone with the corresponding decoder, you can squeeze your entire soliloquy into a three-second burst. Add encryption for free. I believe the arguments for and against such a scheme (cost, convenience, compatibility, etc) are identical to those for and against batched TDD data transfer. Conclusions, if any, left as an exercise.

From _The Milwaukee Journal_, Sunday June 10, 1990, page B3 Arrest May End Mystery Phone Calls Madison, Wis. -- AP -- A 23-year-old Madison man has been arrested in a case involving mysterious phone calls that were created by connecting Madison residents with strangers. He is expected to be charged Monday with 27 misdemeanor counts of unlawful telephone use, according to Madison Police Chief David Couper. Wisconsin Bell officials said they believed the man's arrest last week had solved the mystery that had them searching for problems in their computer software. The man is accused of using the conference call capability of a Madison business to connect residents and companies with each other and possibly with people from other parts of the world. The mysterious calls began about two weeks ago. Although some victims said they were connected to both men and women speaking such languages as Hindi, Spanish and Japanese, authorities speculated that the man may have talked to them himself, pretending to be from another state or a different part of the world. A tracer placed on one victim's telephone led authorities to the suspect, who was arrested after calls made to the person's house Tuesday and Wednesday were traced to the Madison company where he works nights and weekends. The suspect, who has a history of similar offenses, reportedly called two numbers at once and listened silently to the conversation that ensued as the two callers realized that neither had initiated the call, said Jeff Potter, Wisconsin Bell's manager of corporate communications.

Date: 11 Jun 90 01:58:51 GMT Reply-To: Robert Gutierrez Organization: NASA Science Internet - Network Operations Center Hello, There was an episode of "Columbo" that was aired on 6/10/90 (Saturday) which starred Patrick McGoohan and Arthur Hill. It was about an attorney who killed a friend-turned-nemisis who was asking one too many favors. Why am I discussing TV shows in comp.dcom.telecom/TELECOM Digest? Well, in tracking down clues to the killer (McGoohan), Peter Falk as Lt. Columbo used and analyzed a number of TELECOM related items. First, the victim had faxed a letter to his wife, who was staying at a Hawaiian hotel. In asking the deceased's secretary when the fax was sent, the fax log was printed out to show time/date/pages, etc. Does anyone know which fax machine was used (out of curiosity?). More importantly, would there have been a way to forge a fax log, internally, in the machine. Is the "fact" that it is very hard to do a forgery of that type convincing enough to a judge to have the fax log admissable as evidence in a criminal case. Is there any precident pro or con? (ie: does LEXUS or Westlaw have such a subject in their database?). I don't get alt.fax (or alt.anything here), so this is the only other place I could think of asking. Second. Lt. Columbo was amazed by the amount of buttons on the phone of the victim's desk. As a matter of fact, so was I. I never saw so many buttons on a Merlin set before (or what I _thought_ was a Merlin). Columbo wanted to know if there was a way to see what the last call was made to (can you say: Last Number Redial?). After Columbo was (again) amazed by the latest TELECOM technology, the viewing public got to see that the telephone set was....an AT&T ISDN set! (a model 7352 or 7532 ?). Yes, we know ISDN isn't available to individuals, much less small businesses, but, is this what a typical ISDN set is going to look like (or at least an AT&T vision of an ISDN set)? I mean, it has more buttons than a Northern Telcom SL-1 Operator's Console! I would envision that a 'personal' ISDN set would be less intimidating ... or maybe not? Your views on this? Third (and last), Columbo was able to get the calling records of the victim the very next day (local telco records, it appears). The suspect was amazed on how fast he got those records, and again, so was I. I seem to remember discussion here on how hard it was obtaining telephone records (a court order and 10 levels of management were mentioned), but in the case where the records involved were a victim's (and a dead one's at that), is the telco more readily willing to make those records available to a police agency "in the intrest of justice", or some gobbledy-gook like that??? Thanks. Robert Gutierrez Office of Space Science and Applications, NASA Science Internet Project - Network Operations Center. Moffett Feild, California. "If cartoons were made for adults, they'd be shown during prime time." (The Simpsons [4/29/90]) [Moderator's Note: Actually, the time-stamp on FAX messages is not that hard to spoof. Whoever maintains the FAX machine (the 'key operator', as we are sometimes called) in their office controls the time clock inside the machine. Set it for whatever you like, as well as the sender's ID, which is also programmed very easily. Which makes me wonder, are the FAX ID messages now illegal in PA in the wake of the court's ruling? Maybe some FAX user doesn't want to risk having the recipient know who sent the message. PT] ------------------------------ From: Dan Sahlin Subject: Sverige Direkt Organization: SICS, Swedish Inst. of Computer Science Date: Sun, 10 Jun 90 15:13:30 GMT Sweden has recently introduced a service called "Sverige Direkt" (Sweden Direct) which is a list of free telephone number that you can call from a number of countries and you will reach an operator in Sweden. You can the ask for a telephone number in Sweden, and the called party will be charged for the call. I understand that Bell already has a similar service operational. The list of countries and numbers for "Sverige Direkt" are as follows Belgium 11 00 46 Canada 1800 463 8129 Finland 9800 1 0460 Italy 172 0046 Holland 06 022 0046 New Zealand 000 946 Spain 900 99 0046 Great Britain 0800 89 0046 USA 1800 345 0046 It is interesting to see the irregularity of the telephone numbers above, which makes it almost impossible trying to remember them. As I can understand there are two reasons for this irregularity: 1. There is no generally used "800-number". Some similar numbers are used in GB (0800) and Finland (9800). Although you can't see that from the above table, in Sweden we use 020 as our "800-number". We could change that into 0800 as 08 is the area code of Stockholm and no telephone numbers start with a 0, but I haven't heard about any such plans. 2. The telephone numbers for each national "800-number" are allocated locally, so it is not so probable that the same number can be used for the same purpose worldwide. Maybe it is too late now, but a portion of the telephone numbers under "800" could be allocated to a world wide number plan. In the numbers chosen above, I can see attempts in that direction by chosing numbers containing Sweden's country code 46. I wonder if I would reach a Danish operator by dialling 45 instead, or a Norwegian operator by dialling 47 instead. An alternative solution that would make it possible to dial the same number toll free anywhere in the world would be to introduce a pseudo county number for toll free calls. The country code "800" seems to be ideal for this purpose. Finally a strange thing I noticed in the table above: why are there different numbers from Canada and the USA? /Dan Sahlin email: dan@sics.se [Moderator's Note: The different numbers for Canada and the USA may be because the operator in Sweden uses the inbound line to see where the call came from in order to bill it correctly, and it may be there are different rates from Canada to Sweden than from the USA to Sweden.

True, V.32 modems can run at 4 bits/baud (16 symbols), but most are usually run at 5 bits/buad (32 symbols) with trellis coding. Trellis coding provides a type of forward error correction (one extra bit for every four data bits) at a very low level of data transfer. (Is this OSI layer 0.5??? :-). In general, trellis coding gives the modem a performace gain of about one to two db over the uncoded signal. Note that both run at 2400 baud, so that trellis coding sends 12,000 bps, of which 20% is error correction. Gary Segal ...!uunet!motcid!segal +1-708-632-2354 Motorola INC., 1501 W.

My aunt's phone couldn't send out tones, as Alameda has no touch-tone service! It was shocking to know that there still are parts of major metropolitan areas which don't have tone yet.

I converted my two voice lines to Centrex for this very reason, and GTE had no problem with letting me keep my same two numbers. In fact, if a number change had been required I would not have signed up for the service. And though I am not in the habit of complimenting GTE, I must say that their Centrex is a pretty good deal.

Put in more, smaller cells. There is a limit to how small a cell can be. Once that limit is reached, the only way to increase capacity is to add more channels. When you run out of channels, you have maxed out the system. Digital cellular will allow many more channels in a given cell. >And do the digital phones have the same bandwidth as the analog ones? >Do they still give you a full-time 3 KHz channel, suitable for >modeming? If you mean "can I put a modem on the phone?", the answer is "no". If you mean "can I still access analog data services?", the answer is "yes", if the digital cellular system is properly designed. A properly designed digital cellular system is best described as a radio ISDN (Integrated Services Digital Netork), that has one B (bearer) channel that is capable of transmitting data or compressed voice. Typical data rates on the B channel are anywhere from 6kbps to 24kbps, depending on the system. To send voice down this pipe, it must be compressed. Because of the compression, it is impossible to send most modem modulations down the B channel (300 buad Frequancy Shift Keying [FSK] might work, but not 2400bps V.22bis or 9600bps V.32). In order to allow subsribers to access modem based data services, these systems make provisions for a modem pool (again, much like an ISDN) at the connection point to the PSTN (Public Switched Telephone Network). With a modem pool, the connection from the modem to the mobile terminal is digital. Data rates can be up to the maximum B channel rate of the system. In addition, the system can supply an error correcting or error controlling protocol to run between the modem pool and the mobile terminals, giving the subscribe a much cleaner link then could ever be established in an analog cellular enviroment. In addition, connection to an ISDN is straight forward. Digital Cellular will be a great improvent over analog cellular for both the subscribers and the providers. For providers, more subsribers can be supported. For subscribers, ISDN like data services will be available from a mobile phone. As an example of digital cellular done well, I suggest you watch what is happening in Europe, with the Pan-Euorpean Digital Cellular standard (also called GSM).

Date: 11 Jun 90 17:05:16 GMT Organization: Pixar -- Marin County, California From what I've seen of the digital cellular format, it seems to be a way of ripping off the customer to reduce the carrier's overhead. The real fix for high-traffic zones is to add more cells, not increase the capacity of the existing ones at the expense of fidelity and reliability. If there is to be a digital format, it should be able to handle DATA. Using TDM between three moving transmitters on the same channel will probably work poorly even for voice. Would anyone like to help me petition the FCC on this one?

What I envision is a smart-card that contains your ESN, phone number, and billing info. When you slide it in to any cell phone, that phone becomes your phone. It answers calls to your number and lets you make outgoing calls which then get billed to you. The same card could also be used at a payphone. You could have it demand a PIN for each use if you were security conscious. On a related subject, I hope that when European unity comes we can dispense with all those different phone cards and have one card that works anywhere on the continent. Unfortunately this doesn't seem very likely, since the cards all seem to be physically different from each other, at least the ones I've examined. Can anyone tell me how the British card works? On the French card you can see the electrical contacts, but the British one doesn't seem to have any. Is it done electromagnetically? Or with mirrors? ------------------------------ From: Andy Rabagliati Subject: Re: Telenet USSR Organization: INMOS Corporation, Colorado Springs Date: Mon, 11 Jun 90 02:17:28 GMT According to the Colorado Springs, CO {Gazette Telegraph}, the military (I presume COCOM) has prevented US West from going through with their proposed Fibre-optic line across the USSR.

The main problem with this proposal would be the size of the data base required inside of each switch. Think of the routing problems which would occur when any digit sequence could be used to identify a trunk route. Each switch would be required to maintain the telephone number of all of the subscribers in the world. Even small CDO's would require gigabytes of disk storage. In the SS7 network, translations of 800 numbers is done at a central point called the SCP. This could provide a unique service which could provide a lucrativve source of income for service providers. Instead of vanity licence plates, subscribers could buy vanity telephone numbers. Think of it, vanity numbers could be preceded by a distinguishing code.

And now a little personal situation begs the question for those who have maintained that Caller-ID is unnecessary because other methods are available to catch nuisance callers. I have, for a about a week now, received a call on my main private line at about 3:00 am daily. I answer with a groggy "hello", then the caller hangs up. It happens once per evening (morning). Pac*Bell's suggestion is to change my private number, a course of action I find unacceptable. Since it happens only once per day, they don't feel compelled to exert any effort on the matter (terminating traps, or any of the other medieval methods to catch crank callers) so the onus is on me. They have even offered to change my number for free. Now that's really nice of them, since in real terms it's a lot easier for them to type a new number assignment into RCMAC than it is to trap the line (and then have to deal with the results, if any.) With Caller-ID, however, this entire situation would have been settled on the first day. In the meantime, until I'm ready to change my number I guess I'll just plan on waking up at 3am daily.

What we are in effect saying to This would only slow the dealers down momentarily. There are little hand held touch tone generators readily avialable at Radio Shack and better stores. You just hold the device up to the mouthpiece of the rotary payphone, and can merrily beep away. Most of these units have speed dial capabilities, so dialing might become even easier. They start in price at less than $25.00. Although drug dealers aren't terribly bright as a group, I imagine that word of mouth would spread this technology as quickly as the use of pagers spread.

You grew and it couldn't. So now do what you should have done in the first place..." Meanwhile the video is showing people in an office ripping out old 2564 sets (six button, TT 1A2 key) and literally throwing them in the wastebaskets. Then you see them unpacking nice, shiny (but non-descript) electronic, skinny-wire key sets and plugging them into wall mount RJ11C jacks. In case the irony escapes you here, let me explain. Reality would be exactly the reverse. If they (in the video) had bought a phone system that they had outgrown, then they would be ripping out the electronic sets and installing something simple and plain (like 1A2 key sets). You don't suppose that they are trying to imply with the visual that you can get real advanced Centrex features (such as those found everywhere else in the country) here in California? Would Pac*Bell mislead the public? Is the Pope Catholic? John Higdon | P. O.

They are now giving me 40 "Free" minutes of airtime on my VIP Plan. The VIP Plan is $29.95/month + 34 cents/min prime and 20 cents/min non-prime. The new Security Plan is 14.95/month + 38 cents/min prime and 18 cents/min non-prime. Well if you compare the two plans, and use the value of 38/cents per minute, 40 minutes of air time is costs $15.20, add that to the base rate and you get $30.15, so in reality a savings for the first 40 minute of 20 cents. Even a moderate amount of non-prime usage brings the cost of the security plan below that of the VIP plan. Of course if you go beyond that you get 4 cents per minute savings with the VIP plan during prime time but lose 2 cents per minute in non-prime time. So unless your a real heavy duty user of Prime-Time (in which case some of the other bulk minute plans are probably better, go with the security plan (you know the one that used to be no monthly charge). If you are 80% or greater non-prime time you start saving money with the security plan. If your usage pattern varies the following table will give you savings based on 100 minutes of air time.

"The Equifax Report on Consumers in the Information Age" surveyed 2,254 consumers and 916 business executives by telephone during January through April, 1990. Among other findings, the poll revealed widespread public concern about unrestricted Caller ID. Though a 55-43% majority believed that telephone companies should be allowed to sell Caller ID, support for public regulation is clear: 48% say caller ID should be permitted by regulators only if calling parties have the ability to block the display of their number, just over a quarter (27%) say Caller ID should be forbidden by law, and just under a quarter (23%) say Caller ID should be available without any limitation. The poll also found that women "are considerably less likely than men to think Caller ID should be allowed."
