Description
The MT8985 Enhanced Digital Switch device is an
upgraded version of the popular MT8980D Digital
Switch (DX). It is pin compatible with the MT8980D and
retains all of the MT8980D's functionality. This VLSI
device is designed for switching PCM-encoded voice
or data, under microprocessor control, in digital
exchanges,
PBXs
and
environment. It provides simultaneous connections for
up to 256 64 kb/s channels. Each of the eight serial
inputs and outputs consist of 32 64 kbit/s channels
multiplexed to form a 2048 kbit/s stream. As the main
function in switching applications, the device provides
per-channel selection between variable or constant
throughput delays. The constant throughput delay
feature allows grouped channels such as ISDN H0 to
be switched through the device maintaining its
sequence integrity. The MT8985 is ideal for medium
sized mixed voice/data switch and voice processing
applications.
