Patent ID: 7075936

Claim:
For use with voice applications employing a fast pattern processor and a routing switch processor that receive and transmit protocol data units (PDUs), a voice packet processor, comprising: a voice packet controller configured to receive said PDUs from said fast pattern processor and queue said PDUs for processing; a voice packet parser configured to receive said PDUs that are Asynchronous Transfer Mode (ATM) adaptation layer 2 (AAL 2 ) cells containing voice data from said voice packet controller, parse said AAL 2 cells into at least one Common Part Sublayer (CPS) packet, reroute at least one CPS packet from said routing switch processor to said voice packet assembler for incorporation into an AAL 2 transmission stream, modify a channel identifier of said at least one CPS packet to allow for channel identifier mapping, and transmit said at least one CPS packet to said routing switch processor; and a voice packet assembler configured to receive said PDUs that are CPS packets from said voice packet controller, assemble said CPS packets into at least one AAL 2 Cell and transmit said at least one AAL 2 cell to said routing switch processor.
