Cisco BPX 8600 Series Installation and Configuration
Release 9.3.30, Part Number 78-12907-01 Rev. E0, May 2005
Chapter 3 BPX Switch Common Core Components
Broadband Controller Card
The BCC-4V provides a 16 x 32 cross-point architecture that increases the peak switching capacity of
the BPX switch to 19.2 Gbps, with a sustained nonblocking throughput of 9.6 Gbps.
For information to operate the BPX at 19.2 Gbps with the BCC-4V and to program the NOVRAM, see
the Verifying 9.6 or 19.2 Gbps Backplane section of Chapter 13, “Installing the BPX Switch Cards.”
Features
The Broadband Controller Card performs the following major system functions:
• Runs the system software for controlling, configuring, diagnosing, and monitoring the BPX switch.
•
Contains the crosspoint switch matrix operating at 800 Mbps per serial link or up to 1600 Mbps
(BCC-4V).
• Contains the arbiter which controls the polling each high-speed data port and grants the access to
the switch matrix for each port with data to transfer.
•
Generates Stratum-3 system clocking and can synchronize it to either a selected trunk or an external
clock input.
•
Communicates configuration and control information to all other cards in the same node over the
backplane communication bus.
•
Communicates with all other nodes in the network.
• Provides a communications processor for an Ethernet LAN port plus two low-speed data ports. The
BCC15-BC provides the physical interface for the BCC-32.
The BCC-3-BC provides the physical interface for the BCC-3-32M, BCC-3-64M, and BCC-4V.
The following are the features for the Broadband Controller Card:
• 68EC040 processor operating at 33 MHz.
•
32 Mb or 64 MB option for BCC-4.
•
4 Mb of Flash EEPROM for downloading system software.
•
512 Kbytes of BRAM for storing configuration data.
• EPROM for firmware routines.
•
68302 Utility processor.
• SAR engine processor operating at 33 MHz.
•
Communication bus interface.
•
HDLC processor for the LAN connection interface.
•
Two RS-232 serial port interfaces.
