Description

The MT8982 Small Digital Switch (MiniDX) is a nonblocking CMOS time switch with a capacity of up to 64 - 8 bit Time Division Multiplexed (TDM) encoded voice or data channels. MT8982 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 of MT8982 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.
