A voice packet processor for use with voice applications employing a fast pattern processor (FPP) and a routing switch processor (RSP) that receive and transmit protocol data units (PDUs) and a method of operation thereof. In one embodiment, the voice packet processor includes (1) a voice packet controller (VPC) configured to receive the PDUs from the FPP and queue the PDUs for processing, (2) a voice packet parser configured to receive the PDUs that are ATM adaptation layer 2 (AAL 2 ) cells containing voice data from the VPC, parse the AAL 2 cells into at least one Common Part Sublayer (CPS) packet and transmit the at least one CPS packet to the RSP, and (3) a voice packet assembler configured to receive the PDUs that are CPS packets from the VPC, assemble the CPS packets into at least one AAL 2 Cell and transmit the at least one AAL 2 cell to the RSP.
