Introduction
The Multichannel Network Interface Controller for HDLC (MUNICH32) is a Multichannel
Protocol Controller, which handles up to 32 data channels of a full duplex PCM highway.
It performs layer 2 HDLC formatting/deformatting or V.110 and X.30 protocols up to
a network data rate of 38.4 Kbit/s as well as transparent transmission for the
DMI mode 0, 1 and 2. The processed data is passed on to an external memory shared
with one or more host processors.
MUNICH32 is compatible with the LAPD ISDN (Integrated Services Digital Network)
protocol specified by CCITT as well as with HDLC, SDLC, LAPB DMI protocols. It
provides any rate adaption for time slot transmission data rate from 64 Kbit/s down to
8 Kbit/s and the concatenation of any time slots to data channels, supporting the ISDN
H0, H11, H12 superchannels.
Due to these functions the MUNICH32 can be used in a wide area of telecommunication
and data communication applications, e.g. in central office switches, for the connection
of a digital PABX to a host computer, as a central D-channel controller to 32 ISDN basic
access D-channels or as a multiplexer for terminals and other peripherals. Up to
4 MUNICH32s can be connected to one PCM highway, so a D-channel controller with
128 channels can be achieved.
