Almost every exchange in the bell system has test #'s and other "goodies" such as loops with dial-ups. These "goodies" are usually found betweed 9900 and 9999 in your local exchange. If you have the time and initiative, scan your exchange and you may become lucky!

Here are some findings in the 914-268 exchange:

  • 9900 - ANI
  • 9901 - ANI
  • 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

Most of the numbers between 9900 & 9999 will ring or go to a "what #, please?" operator.
