Abstract
Abstract A small and economical voice packet assembling/disassembling (PAD) apparatus, which includes only one packet assembler/disassembler for a plurality of channels. The packet assembler receives coded voice data from a plurality of CODECs provided for each channel, and assembles voice packets by using the coded voice data. The packet disassembler disassembles voice packets to coded voice data and supplies them to a plurality of CODECs provided for each channel.
