MT8931C General Description
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-topoint and point-to-multipoint digital transmission, the SNIC may be used at either end of the subscriber line (NT or TE).
An HDLC D-channel protocoller is included and controlled through a Motorola/Intel microprocessor port.
The MT8931C is fabricated in Mitel's CMOS process.
