A system is configured to facilitate bidirectional voice communication between a number of data and/or telephony devices.

Modem with voice processing capability

A network gateway is configured to facilitate on line and off line bi-directional communication between a number of near end data and telephony devices with far end data termination devices via a hybrid fiber coaxial network and a cable modem termination system. The described network gateway combines a QAM receiver, a transmitter, a DOCSIS MAC, a CPU, a voice and audio processor, a voice synchronizer, an Ethernet MAC, and a USB controller to provide high performance and robust operation.

Cable modem with voice processing capability

A system for tunneling wideband telephony, comprises a communication device configured to produce a compressed wideband audio signal. The compressed wideband audio signal has (i) an audio frequency passband greater than that of an 8 kHz sampled audio signal, and (ii) a compressed data rate that is less than or equal to 64 kbps. The system also includes an apparatus, such as a voice gateway, coupled to the communication device and a data link, including a transcoder bypass configured to convert, without transcoding, the compressed wideband audio signal into a data stream including wideband compressed audio data for transmission over the data link.
