Mitel ST-BUS interface

The MT8931C Subscriber Network Interface Circuit

(SNIC) implements the ETSI ETS 300-012, CCITT

I.430 and ANSI T1.605 Recommendations for the

ISDN S and T reference points. Providing point-to-

point and point-to-multipoint digital transmission, the

SNIC may be used at either end of the subscriber

line (NT or TE).

Low power CMOS technology

An HDLC D-channel protocoller is included and

controlled through a Motorola/Intel microprocessor

port.

Single 5 volt power supply

Applications

The MT8931C is fabricated in Mitel’s CMOS process.
