AUDIO CODEC DEVICE AND ISDN S-INTERFACE SYSTEM

摘要

The audio coding/decoding apparatus is composed of a voice/audio input-output part(1) A/D converting a voice/audio signal of an outside, then delivering the same to an inner of the apparatus and D/A converting restored audio/voice data, then it delivers the same one to a predetermined port of the system; a data input-output part(2) delivering the data to a multiplexing/inverse multiplexing path and controlling procedure of data output to the outside; an audio/voice CODEC part(3) coding the data to deliver the same to the interior of the apparatus and decoding the coded data to deliver it to the voice/audio input-output part; a media multiplexing and inverse multiplexing part(4) being provided with signals respectively which pass through the audio/voice CODEC part and the data input-output part to media multiplex and aligning a frame transferred from ISDN to extract a respective media and a control signal, whereby inverse multiplexing; an apparatus controlling part(7) matching the signal to control I/O decoding of the system and each device, providing mode switching function.
