IMP8980D PCM Digital Switch |
|
| |
|
|
| |
This 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 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. |
