A transcoder converts data between a telephony data format and a packet data format. The transcoder comprises: a digital logic telephony data engine receiving telephony data for the transcoder and transmitting telephony data for the transcoder, the digital logic telephony data engine comprising a frame accumulation buffer; a digital logic packet engine receiving packet data for the transcoder and transmitting packet data for the transcoder; a digital signal processing complex coupled to the digital logic telephony data engine and the digital logic packet engine, the digital signal processing complex comprising an array of digital signal processors; and a host processor coupled to the digital logic telephony data engine and the digital logic packet engine, wherein the digital logic telephony data engine, the digital logic packet engine, and the digital signal processing complex perform media channel processing, wherein the host processor performs control channel processing.
