详细描述

  CN8478EBG - Multichannel Synchronous Communications Controller (MUSYCC) - Conexant Systems, Inc

 
The CN8478, CN8474A, CN8472A, and CN8471A are advanced Multichannel 
Synchronous Communication Controllers (MUSYCCs) that format and deformat up 
to 256 (CN8478), 128 (CN8474A), 64 (CN8472A), or 32 (CN8471A) HDLC 
channels in a single CMOS integrated circuit. MUSYCC operates at Layer 2 of the 
Open Systems Interconnection (OSI) protocol reference model. MUSYCC provides 
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. Under 
minimal host supervision, MUSYCC manages a linked list of channel data buffers 
in host memory by performing Direct Memory Access (DMA) of the HDLC 
channels.
MUSYCC interfaces with eight independent serial data streams, such as T1/E1 
signals, and then transfers data across the popular 32-bit Peripheral Component 
Interface (PCI) bus to system memory at a rate of up to 66 MHz. Each serial 
interface can be operated at up to 8.192 MHz. Logical channels can be mapped as 
any combination of DS0 time slots to support ISDN hyperchannels (Nx64 kbps) or 
as any number of bits in a DS0 for subchanneling applications (Nx8 kbps). 
MUSYCC also includes a 32-bit expansion port for bridging the PCI bus to local 
microprocessors or peripherals. A JTAG port enables boundary-scan testing to 
replace bed-of-nails board testing.
Device drivers for Linux, VxWorks®, and pSOS™ operating systems are 
available under a no-fee license agreement from Conexant. The device drivers 
include C source code and supporting software documents
