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.
