Cisco Systems 8600 Series manual Features

Broadband Controller Card (BCC-32, BCC-3, BCC-4)

The BCC-3 and BCC-32 are functionally equivalent and the BCC-4 is similar except for some additional features such as support of 19.6 Gbps operation. The term BCC is used in this manual to refer to the functional operation of the Broadband Controller Card. When a difference in operation does occur, the specific type of BCC is specified. This card group (see Figure 3-1) provides the following functions:

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 (BCC-32 or BCC-3) or up to 1600 Mbps (BCC-4).

•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 BCC-bc provides the physical interface for the BCC-32, and the BCC-3-bc provides the physical interface for the BCC-3 and BCC-4.

Each Broadband Controller Card includes the following:

•68EC040 processor operating at 33 MHz.

•32 Mb of DRAM for running system software (BCC-32 and BCC-3), 32 Mb or 64 MB option for BCC-4.

•

•

•

•

•

•

•

4 Mb of Flash EEPROM for downloading system software.

512 Kbps 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.
