ADPCM Converter

ADPCM converter is a digital channels doubler. Two digital streams with speed 2Mbit/s (E1) containing 30 channels PCM coded 64 kbit/s are converted in one digital stream with speed 2Mbit/s, containing 60 ADPCM coded channels with 32 kbit/s per channel.

ADPCM converter is designed on the principle to removable PCB modules implemented in 19" rack and it has the possibility to be included in Network Management System for easy configuration and maintenance.
