Description  
The MT8971B (DSIC) and MT8972B (DNIC) 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  
Low power (typically 50 mW), single 5V supply  
Applications  
Digital subscriber lines  
rates up to 160 kbit/s.  
Both devices function  
High speed data transmission over twisted  
wires  
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.
