Description  
This VLSI ISO-CMOS device is designed for  
switching PCM-encoded voice or  
microprocessor control, in  
data, under  
modern digital  
a
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.
