MT9172

The MT9171 (DSIC) and MT9172 (DNIC) are multifunction devices capable of providing high speed, full duplex digital transmission up to 160 kbit/s over a twisted wire pair. MT9172 use adaptive echocancelling techniques and transfer data in (2B+D) format compatible to the ISDN basic rate. Several modes of operation allow an easy interface to digital telecommunication networks including use as a high speed limited distance modem with data rates up to 160 kbit/s. Both devices function identically but with the DSIC having a shorter maximum loop reach specification. The generic "DNIC" will be used to reference both devices unless otherwise noted. The MT9172 is fabricated in Mitel's ISO2-CMOS process.
