General Description
IMP8980D General Description
This CMOS device is designed for switching PCM-encoded voice or data,under microprocessor control, in a modern digital exchange, PBX or Central Office Itprovides 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.
