Method and system for processing voice traffic from a multi-channel link into a VoIP network over a broadband network
First Claim
1. A method for converting circuit-switched voice traffic payload Data. from a multi-channel data link into packet-switched VoIP traffic, comprising:
- terminating the multi-channel data link at a media terminal adapter, wherein the multi-channel data link comprises a plurality of channels and originates from a customer premise equipment private branch exchange;
receiving call data originating from multiple customer premise equipment telephony devices through the multi-channel data link associated with the customer premise equipment private branch exchange;
processing call data at the media terminal adapter according to call control instruction information;
packaging the payload data according to predetermined packaging rules; and
transmitting the payload data according to a voice over internet protocol.

Abstract
A microprocessor and a DSP are coupled with a cable modem and an IAD framer to terminate a DS1 link at a media terminal device. The processor performs call control operations and the DSP performs signal processing, such that call processing occurs at the device. The framer extracts or inserts call control information from robbed-bit signaling bits.
Data streams from the DS1 link are formatted/packetized according to a protocol used by a VoIP network. VoIP is used to transmit the packetized call from the cable modem portion to a CMTS over a broadband network. QoS attributes are implemented on the derived data streams as would be done for calls generated by a standard PacketCable EMTA.
