Description
The MT8931B Subscriber Network Interface Circuit
(SNIC) implements the 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).
An HDLC D-channel protocoller is included and
controlled through a Motorola/Intel microprocessor
port.
The MT8931B is fabricated in Mitel’s CMOS process.
