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
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.
The MT9171/72 is fabricated in Mitel’s ISO
2
-CMOS
process.
