This was reported in the Johnson City Press, Thursday, July 14, 1994. The actual code has not been determined yet: they are leaning towards 249, but 931 is also possible. They would rather use 249 than 931, as 931 might be confused with 901 currently used for West TN: the area containing Memphis. Middle TN would still use 615 (it contains Nashville). When the new area code becomes dialable, and how long permissive dialing will be allowed was not reported. The exact boundaries were also not reported. The article stated that they are doing this as faxes, modems, etc. will soon use up all available numbers in the 615 area code. This has happened pretty quickly, as last year they went from 1+7 dialing of long distance within 615 to 1+3+7 for all inter-lata long distance inside 615 for the very same reason and are soon run out of the numbers that were freed up by that.

Date: 18 Jul 1994 22:03:40 GMT Organization: University of Pittsburgh My Telecommunications Applications class (in the Master of Telecomm program here) is charged with helping the University determine how students, faculty, and staff will access the net from home. We have determined thus far that high-speed modem pools of POTS lines will continue to be the principle access method. (Ie, we will continue to have racks of modems and lots of copper coming in). SLIP is or will be available in the modem pool. We are also interested in ISDN and any other access method. We have not heard of any such 'production' use. We would likely use a UNIX machine as a security gate for the network, direct from the ISDN. Any advice/stories are welcome/appreciated.

It was not uncommon (might still be common now, but I am out of the biz) for alternate (non-AT&T) companies to charge for the rings. They would hide this by always having six second billing AFTER the first minute. Here's how it worked. Lets assume ten rings per minute, one every six seconds. You have signed up with a new long distance carrier, No-Tell. You call grandma. Grandma takes a long time to answer, so you let it ring fifteen times. With AT&T and No-Tell, if Grandma doesn't answer you don't get billed. Both have answer supervision. Let's say Grandma does answer, talks to you for 20 seconds, then forgets she is on the phone and hangs up. With AT&T you would be billed for a one minute call. With No-Tell you would expect a one minute call, but instead you get a 1.8 minute call. 1.5 minutes of rings, and a third of a minute of talk. Voila, you are retroactively billed for all rings as soon as a call supervises. You have to keep pretty close track of your bill to catch that one. Trick number two: In a former life I worked for an LD company that found itself in financial trouble. We'll call it No-Tell, again. Some hotshot fixers were hired, and the first thing they did was raise every rate in the switch by two cents per minute. From one side of the country to the other, not that big an impact. From one side of the county to the other (what a difference a letter makes), a night weekend rate of two cents per minute shot up to four cents a minute, making it one cent a minute higher than AT&T. All No-Tell bills showed clients how much they saved vs. AT&T. Residential bills were saying things like, By Using No-Tell You Saved -3.25. That's right, our bills were showing how much more they spent with No-Tell than they would have spent with AT&T. How did the hotshots deal with this? They raised the AT&T rates by two cents per minute. That's right, our bills just plain lied about the AT&T rates. That was when I quit that job, and started selling yellow page ads. But that is a different story ;).

Says Mark Carriere of Los Angeles, operator of Mark III Entertainment, an 800[sic] sex-talk "service" is going on trial in Alabama. Identifies the prosecutor as Asst. Attorney General Bruce Lieberman, who works for someone named Evans, otherwise unidentified. Says other 1-800 services "may soon be dialing up a court date." I'm wondering about parallels between this case and one that is being talked about a lot lately on the net. In the latter a San Jose computer BBS operator is being tried in Tennessee on porn charges. Now in this case it seems that a federal court in California has held that what the BBS operator is doing is not illegal; but the federal court in Tennessee is claiming that it is illegal there, and since some Tennessee citizens accessed his BBS he can be prosecuted there. ------------------------------ Date: Mon, 18 Jul 94 17:24:48 -0500 From: Peter Eisch Subject: Anyone Use NT Magellan Switches? Reply-To: peisch@cfa.org I'm about to 'take off ' to Ottawa for Magellan training for the MAS and Passport/DPN-100 products. Our implementation is for an IP data network and we're pretty disappointed with the throughput of the MAS product (can't handle a DS1 circuit) though it has an embedded Cisco 2501 router. Where we're going to put the MAS products, wouldn't it be better to put in just the Cisco router with a frame relay interface and use the full DS1 (the cost difference between DS0 and DS1 is negligible in our market)? The NT sales got all huffy when this was suggested as he saw his comission drift away. The NT engineers we've been talking with don't seem to have a clue about IP networks and I'm learning about trunking and things. Are we asking for trouble? Anyone using such devices, please comfort me that the NT sales folks aren't just selling hardware to line their pocket book. peter peter@tahiti.umhc.umn.edu (Peter Eisch) peisch@cfa.org ------------------------------ Date: Mon, 18 Jul 1994 13:55:58 EDT From: Dave Niebuhr Subject: AT&T's New Overseas Transmitting Facility - An Update Last year, I reported that AT&T had filed a tariff to build an overseas cable plant going from Shirley, Long Island, New York, to France. I went by there a little while ago while taking my son and some of his friends to the ocean beach and am offering this update. The building is up and has been for several months; cable, inside conduit, is laid from there to almost where it will have to go underwater to cross the Great South Bay, thence across Fire Island between or near the border of Smith Point County Park and the Fire Island National Seashore. Near the northern edge of the bay, the conduit is above ground and is on what looks to be temporary supports although the currently southern end dips back into the ground. The contractors, some local, some from other areas in New York and some from other states are all involved. A former campground for the County Park has been turned into a staging area for various types of equipment, most notably tankers containing thousands of gallons of potable water. The place is a beehive of activity. It should be noted that New York, Long Island in general and Suffolk County in particular has not even begun to recover from the devistating effects of the last recession. Unemployment is at its still record high and this work is a major boost to our, meaning my hamlet's and two other adjacent one's economies. Yes some of the money will leave the local area; however, we are willing to take any jobs-producing work that we can get. Hat's off to AT&T for selecting the site for its new overseas cable plant in an area that will indirectly benefit many in the future through the taxes that will be paid on the building and its equipment.

Did I miss an article? Are there any others that I may have missed? Thanks, David Esan de@moscom.com [TELECOM Digest Editor's Note: I think you are going to find that when the change becomes official next year, there will be a huge rush of new area codes coming up all over the place, making it difficult or impossible for most people to keep track of them. Carl Moore regularly prepares a history of area code splits and I suspect next year will be a very busy one indeed for him. I post them as I get them, and I suspect by next year this time there will be places that have split even after their original split. Take for example our split to 708 from 312 here a few years ago. Now we are going to have 630 as well. Its going to get crazy.

After an initial preamble, he was told to enter a code on his phone that would give him free time. He entered the number, and the other end shortly hung up without providing him with anything. A month later, he gets a charge on his Pacific Bell phone bill for $30 for two minutes connect time to "Network Information Services" or some such. He tried the 800 number from a pay phone, and instead of giving him an access code, it instructed him to dial a number beginning with 011. Today, on the NBC nightly news, they ran an item concerning this very problem. They explained that, because it was an 800 number, that the called party is able to get your phone number (this I already knew). What they did not explain is why a telephone company will bill a customer on the basis of a request from some called party with an 800 number. Is this some new service? Apparently, Nynex has discontinued such charges. The item said that even if Congress enacts lecgislation to outlaw this sort of fraud, that the companies will just move off shore. Any clues? [TELECOM Digest Editor's Note: Telephone Information Providers can contract with telco to do thier billing for them; they usually do it however through a firm such as Integratel which is already set up for that purpose and which has the billing equipment and procedures already in place.
