• Manufacturer Part Number: pef20324
• Description: Multichannel Network Interface Controller With 128 Channels Extended
• Manufacturer: Infineon Technologies Corporation

1
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.
