ML7074-003 General Description
The ML7074-003GA is a speech CODEC for VoIP. This LSI allows selection of G.729.A, G.726, or G.711 standard as a speech CODEC. The LSI is optimum for adding VoIP functions to TAs, routers, etc., since it has the functions of an echo canceller for 32 msec delay, DTMF detection, tone detection, tone generation, etc.
