The MT8982 Small Digital Switch (MiniDX) is a non-

blocking CMOS time switch with a capacity of up to

64 - 8 bit Time Division Multiplexed (TDM) encoded

voice or data channels. It is a size-optimized version

of MITEL's successful MT8980D Digital Switches,

providing switching capability in cost sensitive

applications such as telephone sets and digital key

systems. The TDM interface to the device is via two

pairs of 2048 kbit/s serial streams with 32 64 kbit/s

channels per stream (ST-BUS). A serial microport

provides access to the device for programming the

required connections.

The serial microport is

compatible with most common microcontrollers. The

unique message mode capability allows the MT8982

to act as a controller for other members of MITEL's

ST-BUS family of components.
