Description

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 kbit/s over a twisted

Low power (typically 50 mW), single 5V supply

Applications

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" will be used to

reference both devices unless otherwise noted.
