Description
This VLSI 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 MT89L80 provides
microprocessor read and write access to individual
ST-BUS channels.
