IMP8980D PCM Digital Switch
This 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 64kbit/s channels. Each of the eight serial inputs
and outputs consist of 32 64kbit/s channels multiplexed to form
a 2048kbit/s ST-BUS stream. In addition, the IMP8980D provides
microprocessor read and write access to individual ST-BUS (Serial
Telecom Bus) channels.
