PURPOSE: A device for transceiving packet data of a vocoder is provided to directly transceive a vocoder packet to a DSP without communicating with an upper controller, thereby reducing operations of the upper controller and increasing the number of channels. CONSTITUTION: A DSP(Digital Signal Processor)(100) directly transceives packet data with a packet network without passing through an upper controller(200) by adding a packet transceiving line. The DSP(100) directly receives packets through a communication line from the packet network, and performs a vocoding process. The DSP(100) transmits converted PCM(Pulse Code Modulation) data to a circuit network. |
