Description
The MT8910-1 Digital Subscriber Line Interface
Circuit (DSLIC)
is designed to provide ISDN basic
rate access (2B+D) at the U-interface. Full duplex
digital transmission at 160 kbit/s on a single twisted
pair is achieved using echo cancelling hybrid (ECH)
technology. This, in conjunction with the high
performance 2B1Q line code, allows the DSLIC to
meet the loop length requirements of the digital
subscriber loops at the U-interface over the entire
non-loaded telephone loop plant.
The MT8910-1 is compatible with the complete
range of Mitel Semiconductor ISDN components
through the use of the ST-BUS interface.
