Description
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.
