The MT9171 (DSIC) and MT9172 (DNIC) are pins for pin compatible replacements for the MT8971 and MT8972, respectively. They are multi-functional devices capable of providing high speed, full-duplex digital transmission up to 160 kbit/s over a twisted wire pair. They use adaptive echo-cancelling 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" is used to reference both devices unless otherwise noted. The MT9171/72 is fabricated in Microsemi ISO2-CMOS process.
