Exchange Scanning                       courtesy of the Jolly Roger 

 
    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.
