- 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!
