Date: Wed, 18 Jan 1995 02:21:15 GMT The cellular carriers appear to be under the mistaken impression that a PIN, transmitted in the clear over the air, will somehow be more secure than a MIN and ESN, also transmitted in the clear, over the air! If only a few subscribers use a PIN, then it will appear to be secure, because those who would clone the MIN and ESN don't bother trying to intercept the PIN. When everybody uses a PIN, then the cloners will have sufficient incentive to intercept and use the PIN along with the MIN and ESN, and we'll be right back where we are today. This is merely another example of an attempt at security through obscurity. I predict that the benefit will be temporary. Dave Levenson Internet: dave@westmark.com Westmark, Inc.

AT&T does offer real-time ANI on 800 numbers, but only if the inbound calls are delivered through AT&T MegaCom(sm) or ISDN service. MegaCom is their bypass service, where a leased T-1 span connects their tandem switch directly to the customer premises. They use wink-start to deliver ANI or DNIS (maybe both?

Randolph U Franklin) I can't comment on the radio aspects, but can shed a little light on university judicial environments. I've been a university faculty member since 78, and, so far as I can see, typical university judicial proceedings for students are run like child abuse determinations, or like the Elizabethan Star Chamber -- in total secrecy and with no one having any statutory rights. Where I work: - Trials, names of the defendant, and verdicts of the student-run judicial board are secret, except for a sanitized one-sentence summary. ("Stolen $1000 computer, Bray Hall, last week, restitution and 100 hours service"). - Even the plaintiff has no right to attend the trial or to learn the verdict. (This came out when a woman accused a man of date-raping her.) - The defendant and witnesses have no right to keep silent, but must answer questions. This rule is in the student handbook. This system survives because the student leaders like it. The secrecy preserves the rights of a defendant who is found innocent, and the general anonymity is considered to be required by the Buckley amendment. This is a law that makes student academic records secret. (In contrast, the comparable rule for people's financial records is that there is not even an expectation of secrecy.) So it's not at all surprising how the student with the radio was treated. Regrettable, yes. Surprising, no. [TELECOM Digest Editor's Note: He wrote me earlier today and now I am unable to find his letter (dammit!) ... he said the reason they were there was because it was believed he was in possession of stolen property. He said he knew that was not the case, had nothing to hide or be concerned about, so he told them go ahead and search. Apparently they did not find any stolen property -- he knew in his own heart he was innocent of that -- but I guess he did not expect them to get off on a tangent about his radio equipment either.

(1-800-827-6364) Reply-To: primeperf@aol.com (Prime perf) The numbers that you have for LDDS/Metromedia are correct for no volume commitment and a one year time commitment. I switched to them about four months ago because of their rates and found the service as good as that from the previous carrier -- Sprint. Besides, the calling card rates are also excellent. You can get AT&T to come up with a better line than the one you are getting if you can commit to more than $200 per month for a period of one to three years. Their Option "S" offering has commitment levels of $200 - $1,000 - $3,000 - $5,000 per month for the one to three year period. The higher the level you are willing to commit to, the better. Then again, if you can get a really good rate and equivalent service from the fourth largest service provider with no volume commitment, who needs any of the three largest! ------------------------------ Date: Wed, 18 Jan 1995 03:08:06 +0100 From: Dik.Winter@cwi.nl Subject: Re: Attention: 800 Number Subscribers (News Alert) > The European position imposes a lottery where there is more than one > applicant for a specific international freephone number.

Could you provide more background, please? The last I heard about international free-phone service was a proposal a few years ago for a new "800" country code. Is that what the Geneva plan is about? If so, I can't see how it would "compromise the value and integrity of existing 800 numbers". The new international numbers would be a whole separate number space, dialed as +800 XXX...., while existing NANP 800 numbers could still be dialed from withing the NANP as they are today: 1-800-NXX-XXXX. What are the details about the proposal for "grandfathering of existing 800 assignments"? Is the idea that any existing NANP 800 number will in the future be reachable as +800-NXX-XXXX as well? (I.e., there will only be a single free-phone number space for the whole world?) That doesn't sound very practical. Also, how can grandfathering be done fairly for *all* existing 800 numbers, including those in other countries? If some company in the US currently owns 1-800-234-5678, and another company in the UK owns 0800-234-567, then who wins? And what about the problem we already have in the US, where the 800 NPA is almost full anyway, which means that we will probably see the introduction of another free-phone NPA soon anyway? How will international free-phone service deal with such new NPAs? In short, what is the numbering space of the proposed international free-phone service, and why exactly would it cause problems?

Actually, 206 is *not quite* completely surrounded by 360. There is a small area at about 3 o'clock (summit of Snoqualmie Pass) where 206 abuts 509.

My question was about INTER-lata rates -- calls **BETWEEN** LATAs. For example, a call from L.A. to San Francisco. I know that INTRA-lata rates have been reduced dramatically by Pacific Bell and even more dramatically by the IXCs, but the last I checked it was still about $0.30 or $0.35 for a one-minute daytime call from one end of the state to the other on any of the Big Three. So, I'll ask the question that has still not been answered: have the IXCs reduced their INTER-LATA rates in line with the new INTRA-LATA rates? (Hint: they can't be undercutting Pacific Bell, because Pacific Bell is still not permitted to carry these calls.) Linc Madison * Oakland, California * LincMad@Netcom.com ------------------------------ Date: Tue, 17 Jan 1995 18:32:18 -0600 From: Paul J Zawada Subject: Long Distance Caller ID I've had a couple of interesting conversations with the folks at Ameritech regarading the delivery of interstate Caller-ID information. I have a question or two regarding the availablity of the above service, so let me summarize and pose a question or two to the readers of TELECOM Digest. Having been frustrated with having Caller ID in Champaign, IL for over six months and having ~70% of my calls come up with "OUT OF AREA", I decided to call Ameritech and try to figure out whether or not I should keep this near-useless service. If I receive a call that originated on one of the two DMS-100s in town, I will get the calling party's number(CPN). Otherwise, I usually get the "OUT OF AREA" message. One time I actually received the CPN for a call from the 415 NPA (I think), but otherwise the CPN doesn't come through for numbers outside of the Champaign area. I had read somewhere that the FCC was going to require carrier (both LEC and IXC) to pass CPN info back and forth where SS7 was in place. Sure enough, I dug a little and found that a "Report and Order and Further Notice of Proposed Rulemaking" was issued with such a requirement. (URL= http://fcc.gov:70/0/Orders/Common_Carrier/orcc4001.txt.) However the order doesn't seem to have any effective date and seems a bit wimpy to me ... With this under my belt, I called the Ameritech residential service number and asked the rep if there was anyway she could find out if and when this was going to happen. I mentioned the above rule to at the very least rationalize to myself that I wasn't off my rocker She said someone would get back with me. About a day later I received a message telling me to call back the same number. After finding my way around the Touch-Tone menu maze, I finally reached a rep who seemed very disinterested in helping me. She told me that the official response from within Ameritech was "No one at Ameritech or AT&T had heard of the particular ruling you mentioned and that the problem was not with Ameritech." She went on to say that I should contact my long distance carrier for more information. The call was over in less than 45 seconds. I spent the day stewing over this terse response and decided I'd call back and tell them I wasn't satisfied with their first answer. So I called back and luckily got on the line with a rep that had a clue. (Yes, there are some RBOC customer reps that are polite and know what they are talking about!) I explained the whole story to him and he replied that even though such a ruling may have been made, no IXC really has done anything to implement interstate Caller-ID nor have any plans been announced. So as a pratical matter, I am out of luck. I also asked him if he could find out if Ameritech uses SS7 for any of their IXC interconnections for the Champaign area. (I already know that the LEC surrounding Champaign, GTE North, is not SS7 capable in this area, so I'm not expecting any Caller-ID information for Intra-LATA calls ouside of Ameritech's service area any time soon.) The rep said he'd try to get a copy of ruling and see if he could dig up any more info. After dealing with my questions we had a fairly good technical discussion that lasted about ten minutes. One of the things that he mentioned was that no DMS-100s could speak SS7. I pushed further and asked him if Northern Telecom didn't support SS7 on any DMS-100s or if it was just Ameritech's DMS-100s that did not support SS7. He said he wan't sure, but he thought NT didn't support SS7 and the DMS-100 at all ... So this leads to the first question: Does the NT DMS-100 (with the proper software of course) support SS7? I find it hard to believe that there is no SS7 capability for the DMS-100 ... can someone prove me wrong? I guess the other questions I have are: How useful is Caller-ID in other parts of the country? Do other folks that have the service get "OUT OF AREA" for 99.5% of their interstate calls, or am I just in the wrong city to get that info? I'd be especially interested to hear how well it works in the Chicago area since Chicago is also served by Ameritech Illinois. Should I dump Caller-ID since I'm getting very little functionality for my $6.50 a month or will things get better? If things will get better, how long should it take before at least some of my friends' out-of-state phone numbers will be lighting up my caller-ID display? Thanks for any info. Paul J.

Lots of long distance calls are having their ID shown ... interestingly, even some recent calls from California in the 415 area code were displayed. Of course all this is relevant to *where* most of your calls originate, and maybe I just lucked out but I would say about 90 - 95 percent of my incoming calls now show Caller- ID, or they show that the caller is blocking it, etc. PAT] ------------------------------ From: stans@panix.com (Stan Schwartz) Subject: New Tennex Codes in 516 Date: 17 Jan 1995 22:40:55 -0500 Organization: PANIX Public Access Internet and Unix, NYC Quick FYI: From the 516-694 exchange (NYNEX), I dialed 1010288 1 908 889 XXXX and the call was completed via AT&T.

Chicago Tonight, a local TV show just had a half-hour debate on that very subject. According to an Ameritech spokesman, the intended plan (as of today) is as follows: 1. 630 will be an overlay area code for all of the 312 and 708 area codes; 2. 630 will initially be assigned for new phones (land and mobile) in 708 area; 3. In early 1996, 630 will also be assigned to Chicago (312); 4. In September 1996, ALL of Chicago and suburbs will require eleven digit dialing, even if you are calling the same area code. 5. Area code 708 is already exhausted. No new cell phones will have 708. The representative from the City of Chicago who appeared on the show is against the new code. The City has filed an objection with the Illinois Commerce Commission (the local PUC), and is considering appealing to the FCC. They claim that this confusion is bad for business. They also claim it to be a safety issue. Small children have too many numbers to learn. Either way, it is a pain in the neck. If I am in 708 and order a second phone line, it will possibly be a 630 line. Regardless, if it goes through, I will have to dial eleven digits for all calls in the future. I think this is the first shot in the war to end seven digit dialing nationwide. We probably will see more of this in the future. Mitchell Weiss mweiss@interaccess.com [TELECOM Digest Editor's Note: Well, there is one good thing to be said about having to dial the area code as well as seven digits on all calls. Once it is made mandatory, we will no longer have to dial *eleven* digits; we will be able to just dial ten digits since the '1' will no longer be needed to show that an area code rather than a local exchange sequence is following. What follows will *always* be an area code ... right? We will be able to use '1' rather than '011' for international dialing since the '1' will no longer be needed domestically. So even though we will be dialing more digits, we will on *true* long distance calls be able to dial fewer digits than now.
