Description
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.
