[comp.dcom.telecom] New York City xxx-9901 Numbers

DREUBEN@eagle.wesleyan.edu) (DOUGLAS SCOTT REUBEN) (06/16/90)

In response to Carl Moore's posting about 212/718 (and 516 and lower
914) exchanges "identifying" themselves by dialing xxx-9901...

Try calling 718-855/643/403/(+ others) -9901. It used to say all the
exchanges in the Bridge Street (Brooklyn) 5ESS. Now all it says is
"You have reached the Bridge Street #5 ESS, now including the 403
code...". Great, if I were working for NY Tel I'd really want to know
that it "now" includes the 403 code! What about the other 7
exchanges?!?

Oh, and this only seems to work on NY Tel's NYC Region DMSs and 5ESSs.
If you dial xxx-9901 on older systems (Crossbar, 1/1AESS, Step-by-Step
(are there any left?)), you get a computer telling you the area code
and the exchange you had dialed. (IE, 7-1-8-6-4-3.) Sounds like the
958 ANA (?) voice to me.

In case anyone cares, here are some 99xx "suffixes" that 'work' in NY:

9901- (see above)
9902- sometimes like 9901
9907- 600 ohm terminator (or something like that...it just picks up the 
      phone and hangs...someone told me that 9907/9908 used to be looops).
9908- "
9941- repair office, used in some exchanges (611 in NYC/Long Island and 1-890-
      6611 gets the same thing is Westchester).
9950- Business office in some exchanges
9951-9969- Standard recordings, such as "The call you have made requires
           a 25 cent [10 cent in NY Tel's CT service area] deposit.." Try
           718-520-9960.
9970- Busy (also works in North Jersey, and upstate NY, like Ithaca and 607-
           257 Xbar exchange)
9971- Reorder. More prevalent on the Xbars, but a few older ESSs give a reorder
      on -9971. Also works occasionally in North Jersey (201).

Finally, does anyone know what a "DS-0" switch is? (Try 516-724-9901.)
Is a DS-0 some sort of DMS??

If you are calling long distance, calls to 9901 RECORDINGS (ie, DMS
5ESSs) don't bill/return supervision, while calls to the older Xbars
and 1/1AESSs usually do bill. Of course, you can just use MCI and not
worry about it - they'll bill you in any case! :-)
