GENERAL DESCRIPTIONS

MX97102 implements the 4-wire S/T interface used to link voice/data terminals to an ISDN. It is designed for the user site of the ISDN-basic access, two 64kbit/s B channels and a 16kbit/s D channel.

MX97102 can be mainly divided into three portions according to their interfaces. Except these three interface functions, it also provides the LAPD controller which handles the HDLC packets of the ISDN D-channel for the associated microprocessor.
