Quick Detail:
CN8474AEBG Multichannel Synchronous Communications Controller (MUSYCC)
Description:
The CN8478, CN8474A, CN8472A, and CN8471A are advanced Multichanne
Synchronous Communication Controllers (MUSYCCs) that format and deform
to 256 (CN8478), 128 (CN8474A), 64 (CN8472A), or 32 (CN8471A) HDLC
channels in a single CMOS integrated circuit. MUSYCC operates at Layer 2 o
Open Systems Interconnection (OSI) protocol reference model. MUSYCC pro
a comprehensive, high-density solution for processing HDLC channels for
internetworking applications such as frame Relay, ISDN D-channel signaling
X.25, Signaling System 7 (SS7), DXI, ISUP, and LAN/WAN data transport. U
minimal host supervision, MUSYCC manages a linked list of channel data bu
in host memory by performing Direct Memory Access (DMA) of the HDLC
channels.
Applications:
• ISDN basic-rate or primary-rate interfaces
• ISDN D-channel controller
•Routers
• Cellular base station switch controller
• CSU/DSU
• Protocol converter
• Packet data switch
• frame relay switches/frame Relay Access
Devices (FRAD)
• DXI network interface
• Distributed packet-based communications
system
• Access multiplexer/concentrator
