Abstract:
1. For use with a processor-controlled digital communication device adapted to process digitally encoded voice samples transported over a time division multiplex (TDM) communication path for assembly in accordance with a communication protocol, so that said voice samples may be transmitted over a digital communication link to a destination receiver device, a method of processing said digitally encoded voice samples for delivery to said processor-controlled digital communication device comprising the steps of: (a) performing echo cancellation on said digitally encoded voice samples as received from said TDM communication path, and transporting echo cancellation-processed voice sample signals over said TDM communication path to downstream processing; (b) performing compression of said echo cancellation-processed voice sample signals as received from said TDM communication path from step (a) and transporting compressed, echo cancellation-processed voice sample signals over said TDM communication path to a downstream host processor of said processor-controlled digital communication device; and (c) coupling said compressed, echo cancellation-processed voice sample signals as transported to said TDM communication path in step (b) to said host processor of said processor-controlled digital communication device for assembly into a voice output stream in accordance with said communication protocol.
