BPX Switch Operation
BPX Switch Operation
With the BCC-4, the BPX switch employs a redundant 19.2 Gbps non-blocking crosspoint switch
matrix for cell switching. The switch matrix can establish up to 20 million point-to-point
connections per second between ports. A single BPX switch provides twelve card slots, with each
card capable of operating at 800 Mbps for ASI and BNI cards. The BXM cards support egress at up
to 1600 Mbps and ingress at up to 800 Mbps. Access to and from the crosspoint switch is through
multi-port network and user access cards. It is designed to easily meet current requirements with
scalability to higher capacity for future growth.
A BPX switch shelf is a self-contained chassis which may be rack-mounted in a standard 19-inch
rack or open enclosure. All control functions, switching matrix, backplane connections, and power
supplies are redundant, and non-disruptive diagnostics continuously monitor system operation to
detect any system or transmission failure. Hot-standby hardware and alternate routing capability
combine to provide maximum system availability.
