Introduction

The MUNICH128X is a 128-channel WAN Protocol Controller which provides four

independent 24/32-channel HDLC controllers, each with a dedicated 64-channel DMA

Controller and a Serial PCM Interface Controller. The device is offered in a 160-

pin MQFP package, making it ideal for high-port-density applications.

The MUNICH128X provides capability for up to 128 full duplex serial PCM channels. The

chip performs layer 2 HDLC formatting/deformatting or V.110 or X.30 protocols up to

a data rate of 38.4 kbit/s (V.110) or 64 kbit/s (HDLC). The MUNICH128X also performs

transparent transmission for DMI modes 0, 1, and 2. Processed data is transferred to

host memory via the PCI interface or de-multiplexed bus interface.

The MUNICH128X is compatible with the LAPD ISDN (Integrated Services Digital

Network) protocol specified by CCITT, as well as with HDLC, SDLC, LAPB and DMI

protocols. It provides rate adaptation for time slot transmission from 64 kbit/s down to

8 kbit/s and the concatenation of time slots, supporting the ISDN H0, H11, H12

superchannels.
