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.
