Description

This VLSI ISO-CMOS device is designed for

switching PCM-encoded voice or

microprocessor control, in

data, under

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.
