Description

•

Per channel tristate control

The MT89L85 Enhanced Digital Switch device is an

upgraded 3-volt version of the MT8985 Digital

Switch. It is pin compatible with the MT8985 and

retains all of the MT8985's functionality. The

enhanced digital swtich is designed for switching

PCM-encoded voice or data, under microprocessor

control, in digital exchanges, PBXs and any ST-BUS/

MVIP environment. It provides simultaneous

connections for up to 256 64kb/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 MT89L85 is ideal for medium sized

mixed voice/data switch and voice processing

applications.
