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
128 64 kbit/s channels. Each of the four serial inputs
and outputs consist of 32 64 kbit/s channels
multiplexed to form a 2048 kbit/s ST-BUS stream. In
addition, the MT8981 provides microprocessor read
and write access to individual ST-BUS channels.
