ABSTRACT:
An echo cancelling system comprises a system controller for directing inbound and outbound PCM signals to one of two echo canceller modules. The system controller receives status information from the echo cancellers and maintains state information pertaining to the active echo canceller, in order to allow seamless switchover from one echo canceller to the other without interrupting service.
