Method and apparatus for monitoring a network for customer signaling during the term of a call.

摘要

A network monitor and associated control system is provided to monitor a toll network for customer signaling. A multi-tone signal processor (213,214) and associated control (215) is provided such that when signaling is detected, such signaling is validated against a provisioned list. A valid signal is reported to a central control (203) of the network switch, which takes action in response to the signal. <IMAGE>
