PEB20321H - Brand New Infineon Telecommunication Interface ICs
-
Overview
The MUNICH32X is an enhanced version of the Multichannel Network Interface Controller for HDLC, MUNICH32 (PEB 20320, refer to the User’s Manual 01.2000).
Key enhancements include:
• a 33 MHz/32-bit PCI bus Master/Slave interface with integrated DMA controllers for higher performance, lower development effort and risk,
• symmetrical Rx and Tx buffer descriptor formats for faster switching,
• an improved Tx idle channel polling process for significantly reduced bus occupancy,
• an integrated Local Bus Interface (LBI) for connection to other peripherals that do not have a PCI bus interface with DMA capability,
• an SSC interface and
• an IOM®-2 interface.**The MUNICH32X provides capability for up to 32 full-duplex serial PCM
channels. It performs layer 2 HDLC formatting/deformatting or V.110 or X.30 protocols up to a network data rate of 38.4 Kbit/s (V.110) or 64 Kbit/s (HDLC), as well as transparent transmission for the DMI mode 0, 1, and 2. Processed data are passed on to an external memory shared with one or more host processors.**
The MUNICH32X 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 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.
**The MUNICH32X may be used in a wide range of telecommunication and
networking applications, e.g.**
• in switches to provide the connection to a PBX, to a host computer, or as a central Dchannel controller for 32 D-channels,
• for connection of up to 4 MUNICH32Xs to one PCM highway to achieve a D-channel controller with 128 channels,
• in routers and bridges for LAN-WAN internetworking via channelized T1/E1 or multiple S/T interfaces,
• for wide area trunk cards in routers and switches (Frame Relay, ISDN PRI, Internet Protocols, etc.), and
• for centralized D- or B-channel packet processing in routers, switches (Frame Relay, Q.931 Signaling, X.25, etc.) -
