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
