Abstract:
A transcoder for converting data between a telephony data format and a packet data format, comprising:a digital logic telephony data engine receiving telephony data for said transcoder and transmitting telephony data for said transcoder, said digital logic telephony data engine comprising a frame accumulation buffer; a digital logic packet engine receiving packet data for said transcoder and transmitting packet data for said transcoder; a digital signal processing complex coupled to said digital logic telephony data engine and said digital logic packet engine, said digital signal processing complex comprising an array of digital signal processors; and a host processor coupled to said digital logic telephony data engine and said digital logic packet engine, wherein said digital logic telephony data engine, said digital logic packet engine, and said digital signal processing complex separate media channels from control channels in input data, route the control channels to the host processor, and perform media channel processing, wherein said host processor performs control channel processing; wherein data is converted from the packet data format to the telephony data format by removing jitter from a coder-decoder data frame, said coder-decoder data frame based on said packet data.
