MT8980DE Datasheet PDF - Mitel

●Description

●This VLSI ISO-CMOS device is designed for switching PCM-encoded voice or data, under microprocessor control, in a modern digital exchange, PBX or Central Office. It provides simultaneous connections for up to 256 64 kbit/s channels. Each of the eight serial inputs and outputs consist of 32 64 kbit/s channels multiplexed to form a 2048 kbit/s ST-BUS stream. In addition, the MT8980 provides microprocessor read and write access to individual ST-BUS channels.
