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 ac-
cording 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.
The first, S/T interface controller, provides all electrical
and logical functions of the S/T interface, such as S/T
transceiver, activation/deactivation, timing recovery,
multiframe S and Q channels, and D-channel access
and priority control for communicating with remote
equipments.
The Second is the microprocessor interface controller
which offers the registers compatible with Siemens
PSB2186, provides three types of microprocessor in-
terface, such as Motorola bus mode, Intel multiplexed
mode and Intel non-multiplexed mode.
The last portion is the GCI interface controller which is
used to connect different voice/data application mod-
ules for local digital data exchangements.
