2 Wire Full-Duplex 2B+D (80/160 Kbps) Data Format Digital Subscriber Network Interface Circuit (range Up To 4 KM)The MT9171 (DSIC) and MT9172 (DNIC) are pin for pin compatible replacements for the MT8971 and MT8972, respectively. They are multi-function devices capable of providing high speed, full duplex digital transmission up to 160 kbps 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 kbps. 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.
