I can conceive of no useful purpose in providing the facilities to terminate a central office line from each CO in an official PBX trunk (the necessary interface) at manual DSA position used for verification. Telephone companies *discourage* verification, and certainly would not provide such direct access as a benefit to the customer; if the customer wants verification, then they dial "0". No telephone company personnel would want to verify a line, either from a business office standpoint or for installation/repair purposes. Even a craftsperson working on a repair problem has no need to talk to a verification operator because a verification position has no test apparatus and can tell a craftsperson almost nothing useful to facilitate a repair. A craftsperson working on a repair deals with a local test desk equipped with various test and measurement apparatus, which is furthermore staffed by a technically-qualified craftsperson. It seems more likely that you dialed a number which terminated at a local test desk in a repair service bureau. Every CO that I have seen has a local number which terminates at a local test desk, which may be local or remote to the CO; in some cases the local number is less than 7 digits, like "770" or "951". While a local test desk certainly has access to test trunks from the affected CO and could in effect perform the function of "busy line verification", I am rather surprised that they would do so without challenging your identity. Then again, I suppose that anything is possible in downstate New York. :-) Also, according to an official New York Telephone Maintenance Telephone Directory for the NYC and LI areas, the 9901 number (along with the 9970) was commonly used as a "charge/no charge" test line used for toll and coin line supervision testing. > In about 1973 or '74, we could no longer reach a verification operator > on official-1, but rather, 234-9901 would bring one up capable of > verifying anywhere in 516. Almost all No. 1 and No. 3 Toll Board (combined with DSA) positions have multiples for outside CO lines which terminate in the position using an "official PBX trunk" circuit. It is most likely that you found such a direct CO line. However, I would be extremely surprised if in fact all of area code 516 was verified at a common DSA facility, since there are MANY CO's in Nassau and Suffolk counties. I suspect that area code 516 is broken up into at least 3 DSA facilities which handle verification. <> Larry Lippman @ Recognition Research Corp. - Uniquex Corp. - Viatran Corp. <> UUCP {allegra|boulder|decvax|rutgers|watmath}!sunybcs!kitty!larry <> TEL 716/688-1231 | 716/773-1700 {hplabs|utzoo|uunet}!/ \uniquex!larry <> FAX 716/741-9635 | 716/773-2488 "Have you hugged your cat today?"
