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-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 MT8931C is fabricated in
process.
