Abstract

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.

Claims24

Dependent claims

A media terminal adapter for supporting bidirectional exchange of packetized voice or voice data over a hybrid fiber coaxial (HFC) network, the media terminal adapter including a digital device configured to provide:

a subscriber-side interface adapted to couple to a subscriber telephony device;
a network-side interface adapted to couple to a cable modem;
a host application programming interface (HAPI) that includes a software messaging interface to a voice and data digital signal processor (DSP);
a voice over home network (VOHN) interface that includes a software messaging interface to a remote home phone network alliance (HPNA) media adapter;
and
a gateway control protocol (GCP) interface adapted to communicate with a GCP logic module, wherein the GCP interface is configured to support signaling and encapsulation elements of a public switched telephone network (PSTN).
