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
process.
