TELECOM Digest Wednesday, 4 Jan 1984 Volume 4 : Issue 3 Today's Topics: Access Charges and other Break-Up issues dial tone after hangup Dial-tone after hanging up new Bell Atlantic UK Telephone Dialing Codes Wiring charges Cheap Error-Free Phone Communications Access misnomer Extended area calling Re: UK codes ---------------------------------------------------------------------- Date: 2 Jan 1984 1949-EST From: John R. Covert <RSX-DEV at DEC-MARLBORO> Subject: Access Charges and other Break-Up issues Nat at Yale is concerned about rehashing old material, but everyone is confused about this, so we probably should rehash it. There is absolutely no question that LD rates have been subsidizing local rates. Though a lot of the record keeping at AT&T is confusing, this is obvious without looking at AT&Ts records: Those companies which were not Bell System companies have been getting direct payments from AT&T for the long distance traffic offered to AT&T by the independents. In fact, many very small independent companies are only profitable because of this subsidy, which is much greater than the cost of the switching equipment within their plant to provide long distance service. "Access charge" was probably a poor choice of terms, since it has been so misused by calling it a "Long-Distance-Access-Charge." It isn't; it is a network access charge. An access charge for the access to any part of the telephone network. You're right; this is what your local phone rate is supposed to pay. But your local rates are determined by local regulatory authorities, and the FCC has created a national problem (while trying to solve another national problem -- more later). The FCC wants this solved with a national-scope solution. Congress also wants a national-scope solution, but a different one. One alternate solution is to make the LD carriers continue to pay the same amount to the local companies by making the cost of the LD carrier's connection much higher than it really costs, thereby continuing the subsidy. The problem with this is that this encourages the LD carrier to build facilities directly into large LD user's facilities (into corporate headquarters, large hotels, and airports (which they're already doing!)) thereby BYPASSing the local company. The local company now has lost NOT ONLY the subsidy over and above the cost of providing this service, but also the legitimate revenue associated with the cost of this service. (This service is, in fact, the non-fixed-cost part of an LD call, which the LD carrier will be paying to the local company. Determining the rate for this is bizarre, as well. In most cities, each exchange has direct toll trunks for AT&T traffic, (this is not the case in the New York Metro area, but a realignment of tandems may make it the case). Thus the variable cost part is not much different than the variable cost part of a local call. So another patch gets applied -- the Universal Service Fund -- which is paid into by all LD carriers. Now we've got another problem -- defining who pays how much into this universal service fund for what. If I have a private right-of-way over which I operate long-distance service for myself (within my company, say within a power company along my power transmission facility), is that bypass, and do I have to pay into the universal service fund? The question about long-distance calls within a local company requires an understanding of the LATA concept. Even though both ends of an LD call may be in the same company (e.g. Boston and Springfield are both served by New England Telephone within Massachusetts), unless they are in the same LATA, the LD service must be provided by an LD company. The LATAs were presumably set up with the capabilities of the local companies in mind; only the local company may provide service within the LATA. This means that MCI may not provide service between, for example, Montauk Point (the eastern end of Long Island) and West Point (these are the eastern and northern points of the NYC Metro LATA) but can provide service from West Point to Newburgh (assuming the New York PUC grants them a franchise). I mentioned earlier that this new national problem solves another national problem. That problem was the monopoly of AT&T. (Though this may have been one case where a monopoly was in our national interest -- it was a monopoly and was against the law. So either the law had to be changed or the monopoly had to be broken up.) All the comments "If it ain't broke, don't fix it" ignore what was broken -- not the phone system, but the free-enterprise system. By breaking off the local companies from AT&T, the other LD carriers will now, presumably, be able to compete fairly with AT&T. I still think AT&T will win, even in the free enterprise system. If they really are allowed to compete -- but it's likely that most of their rate reductions will be challenged as being anti-competetive, as using their huge corporate size to introduce products at below cost. And here we leave the realm of telephony, and need discuss this no further in this digest. ------------------------------ Date: Mon, 2-Jan-84 20:33:32-PST From: Lauren Weinstein <vortex!lauren@RAND-UNIX> Subject: dial tone after hangup The exact behavior of dialtone return to a callee after calling party hangup varies from CO to CO, depending on the type of switching equipment, and also sometimes on the origin of the call. Generally, ESS offices revert to dialtone quickly at hangup, while #5 Xbar may take 20 to 25 seconds -- during which time enough line noise may be present to keep VOX answering machines taping away merrily. On intraoffice calls in Xbar, and sometimes even occasional interoffice calls, immediate reversion to dialtone may occur, but this is fairly sporadic and installation dependent. With Step X Step offices, all bets (as usual) are off -- most Bell System step offices revert to dialtone immediately, while many GTE exchanges may or may not revert at all -- depending on the exact wiring of the final selector banks in the particular office. In fact, in GTE step, a single line may change in this characteristic at random times, since routine equipment changes may result in altering that "critical" wiring. In cases where the line never self-reverts, even a VERY short momentary interruption of the line is enough to clear the circuit and restore dialtone. I have considerable experience in radio/teleproduction, voiceover work, and the like, and I can tell you that 90% of the time, any "telephone conversations" you hear in radio spots are carefully edited for maximal effect, with hangups, dialtones, dialing, and similar "effects" separately added in most cases. So, don't try to draw ANY conclusions about the "real world" from what you hear in radio commercials! --Lauren-- ------------------------------ Date: 3 Jan 1984 0011-EST From: John R. Covert <RSX-DEV at DEC-MARLBORO> Subject: Dial-tone after hanging up This Hollywoodization of the phone system has always bothered me, too. What happens is going to vary depending on the type of exchange at each end and any tandems in between. The cases of an outgoing caller getting an immediate dial-tone when the called party hangs up are VERY rare, in fact, I can't think of any specific examples; but there probably are some. The called party is more likely to get dial tone in a shorter amount of time after the calling party hangs up, but this, too, is seldom immediate. Hollywood also likes to have people flash the switchhook rapidly whenever the call is disconnected. I suppose people really do this, but the reason for it comes from the days when most exchanges were manual -- this was to recall the operator! But even in the later days of cord boards, this was not the proper way to recall an operator; a single, deliberate flash (just like the one to activate add-on) would activate a circuit in the cord which flashed until the operator responded. ------------------------------ Date: 3 Jan 1984 0015-EST From: John R. Covert <RSX-DEV at DEC-MARLBORO> Subject: new Bell Atlantic Even though both Diamond State Telephone and C&P of Maryland are both under the new Bell Atlantic, they are still separate companies and are separately regulated by the separate state PUCs. ------------------------------ Date: 3 Jan 1984 0053-EST From: John R. Covert <RSX-DEV at DEC-MARLBORO> Subject: UK Telephone Dialing Codes According to British Telecom; the places mentioned in Carl's message cities with "All-figure numbers." To call one of these numbers, dial all the figures. There is no separate dialling code. What this means is that people in those cities are supposed to ALWAYS state their number in the format 021-246 8071. People in other cities are required to show there number as follows: Aberdeen (0224) 34344. The exchange name is required by callers within the local call area so they can refer to their list of local call dialling codes for the correct code to use. This is one of the more bizarre features of the British telephone system -- someone from a town adjacent to Aberdeen will not dial 0224; they'll probably dial something like 93. And on the other side, they might dial 96. Back to the cities with all-figure numbers... Did everyone notice that the Birmingham is 0B1-xxx xxxx, Edinburgh is 0E1-xxx xxxx, etc? This continues in the Numbering Plan... Reading is 0RE4, Coventry is 0CO3, (in England, the O was on the zero -- new phones have no letters, though) Worcester is 0WO5, Cambridge is 0CA3, Dover is 0DO4. Of course, this isn't true for all cities, but it is for quite a few. ------------------------------ Date: 3 Jan 1984 0121-EST From: John R. Covert <RSX-DEV at DEC-MARLBORO> Subject: Wiring charges I'm sure this is a case where the tariffs really need to be consulted. Fortunately, Massachusetts has no wiring charges, but for a brief period they had an extension charge which I ran afoul of because I had given them all the registration numbers. I was able to convince them that I could not have more extensions than jacks, and they took the charge for the extra one off. Doesn't the wiring charge apply to the number of New York Tel maintained jacks? Can't you use any one of the existing New York Tel jacks as the Network connection point, and run your wiring from there? (You can in Massachusetts -- of course, this is a mess if none of the jacks are in a good location to run a wire back to the central distribution point.) It seems you should be able to tell them "This is the only jack I want; I'll connect my wiring here." Here in Massachusetts I was told that this was my only option... they would not even come out if I wanted them to to install a new network interface. (That seemed like a silly answer; they certainly would have come out and disconnected everything and installed a new jack in the basement if I wanted them to. For a price. It wouldn't have been the same cute little jack with the test button, but that's their problem as long as I have enough extra phones to be sure any problem is theirs before making them come out.) If you can get the whole wiring charge (you said $2.81, plus tax) eliminated for $40, then DO IT unless you're planning on selling the house within the next year and a half! On the Touch-Tone charge; if you aren't using it, they can't make you pay for it. (If your exchange can't block you from using it, then they still can't charge you for it, but they can charge you retroactively (to the date of registration), disconnect your service, or request the state to bring fraud charges against you if they find you have been using it.) ------------------------------ Date: Tue, 3 Jan 1984 04:19:04 EST From: HAGAN.Upenn-1100@Rand-Relay (John Dotts Hagan "The Kid") Subject: Cheap Error-Free Phone Communications I am interested in statistics about the expected error rate when using modems in the U.S. For example, how many errors should I anticipate when sending to CA from NY over 1200 baud using 212A Bell modems? I know that the above question is very dependent on many factors, but I was wondering if anyone had any information or pointers to literature that would claim evidence about one protocol or another being better or worse over long distance, ect. Specifically, I want to send "error-free" data from a central host to several receiving sites throughout the U.S. I was wondering how I could cheaply reach that goal. One route I know of is error detecting/correct modems (about $1000). Any alternative ideas? Any facts on expected error rates? Thanks in advance! John Hagan P.S. Please send to me personnally (Hagan%UPenn-1100@CSnet-Relay) since I do not receive this digest regularly. ------------------------------ Date: Tuesday, 3 Jan 1984 06:15:50-PST From: decwrl!rhea!donjon!goldstein@SU-Shasta Subject: Access misnomer Nat Mishkin's comment about "access charges" points out the misnomer which they are. They aren't there for YOUR access to L.D., they're there for L.D.'s access to you! BUT that doesn't mean they are purely there because of LD cost. Somewhere in the distant past (the 30's), the Supreme Court ruled that phone facilities used for both interstate and intrastate calling were legally in both jurisdictions. That meant that AT&T had to "separate" its toll revenues, paying back some to the local telcos for use of their facilities. Originally, the percentage of local line usage that was interstate was the percentage of the local investment that was moved to the interstate rate base. Later that got marked up, constituting a subsidy. For example, if 10% of all calls in a state were interstate, then (original rule) 10% of the cost of local lines was legally ATT Long Lines', and 90% the local telcos. Today that would be over 30% ATTs, because of the markup (called SPF, subscriber plant factor). With competition, such orderly separations don't work. Which interstate carrier pays? Hence access fees. The FCC wanted originally to have the local customer pay the INTERSTATE portion of the FIXED cost, as an "access charge", to REPLACE what ATT had been picking up as their share of the rate base (i.e., the interstate share). This is not nonsensical at all, since the COST of providing local service would not go down if there were no interstate calls. But it did constitute an effort by the FCC to get around the "separations" idea. Politics being what it is, that plan is now being replaced by who-knows-what. Fred ------------------------------ Date: Tue 3 Jan 84 14:58:36-MST From: William G. Martin <WMartin@SIMTEL20.ARPA> Subject: Extended area calling For those that have asked, by the way, I am in Southwestern Bell territory, in St. Louis, Missouri. The telephone to which I wanted to get some sort of extended local service is in Warrenton, MO, and is serviced by "an independent", as the SW Bell Business Office people daintily put it. They say that there is no way for me to get any low-cost extended service to include that exchange or number. Since it is another company, they can't (or won't) say if that company offers any option to make that number local to me. I am guessing that anything they might provide would be one-way, not allowing local-rate calls from a St. Louis number TO that Warrenton number. After all, the independent could only sell a service which would reduce its own revenues; it couldn't (or wouldn't be allowed to) reduce SW Bell revenues by selling its own customers a service which would reduce the costs to another company's (SW Bell) customers by eliminating LD charges those customers would otherwise pay.

(Reminder: X is any single digit; N is any single digit EXCEPT 0 or 1.) ------------------------------ End of TELECOM Digest *********************
