Early versions of the 5ESS software relied on the data base to allow the hardware to decode DTMF or ignore it. When one of these central offices were first cut it seems that a significant number of telephones in town (Port St. Lucie, Florida) no longer were able to outdial. (The customers were using DTMF and not paying for it.) This prompted a hasty software change to provide 2 options for DTMF: 1) Ignore it on lines not paying for the service. (The original scheme.) 2) Allow it on all lines, but prepare a report of those lines using DTMF but not authorized. It is then up to the telco to take appropriate action. Such as sending warning letters to encourage customers to sign up for DTMF before reverting back to option # 1. It is up to the telco to decide which option is in force upon cutover, but most opt for #2. Jim Smithson ihnp4!ablnc!jrs2 (305)660-6991 Ex-5ESS System Integrity Flunkie for Bell Labs
