EXCHANGE SCANNING (99XX)
|
|
|
|
Almost every exchange in the Bell System has test #'s and other "goodies" such
|
|
as loops with dial-ups.
|
|
|
|
These "goodies" are usually found between 9900 and 9999 in your local exchange.
|
|
If you have the time and initiative, scan your exchange and you may become
|
|
lucky!
|
|
|
|
Here are my findings in the 914-268 exchange:
|
|
|
|
9901 - Verifaction (recording of a/c and exchange)
|
|
9927 - Osc. tone (possible tone side of a loop)
|
|
9936 - Voice # to the telco central office
|
|
9937 - Voice ! to the telco central office
|
|
9941 - Computer (digital voice transmission?)
|
|
9960 - Osc. tone (tone side loop -- may also be a computer in some exchanges
|
|
9961 - No response (other end of loop?)
|
|
9962 - No response (other end of loop?)
|
|
9963 - No response (other end of loop?)
|
|
9966 - Computer (see 9941)
|
|
9968 - Tone that disappears--responds to certain touch tone keys
|
|
|
|
|
|
What you find depends upon the switching equipment in the exchange and the
|
|
Telco operating company.
|
|
|
|
Since I have done the above 914-268-99XX scan, Congers (268) has installed new
|
|
switching equipment (DMS100). Some of the numbers are the same, but I have
|
|
noticed that on the DMS100, the recordings are also stored in this area.
|
|
268-9903, 9906, & 9912 are all different recordings. Also, there are 2
|
|
fortress fone recordings at 268-9911 (deposit 5 cents or else) and 268-9913
|
|
(deposit 10 cents).
|
|
|
|
In some areas (like Delaware), I have noticed that 9906-7 is ringback. If you
|
|
find anything interesting, be sure to drop TAP a line.
|
|
|
|
Have phun and remember it's only local call to see what your CO has in store
|
|
for you!
