TR TSY 000181 : ISSUE 1

Presents Bellcore's view of proposed generic requirements for dual-tone multifrequency (DTMF) receivers for end-to-end signalling across networks. DTMF signalling uses voiceband tones to send address signals and other digital information from pushbutton telephones and other customer premises equipment. The end-to-end signalling capability is necessary whenever customer-generated DTMF signals are sent, without generation, beyond the originating end-to-end switch; e.g., to remotely access or control a new network feature.
