BPX Switch

•The BXM cards provide a range of trunk and service interfaces and support ATM Forum Standards UNI 3.1 and ATM Traffic Management 4.0 including ABR connections with VS/VD congestion control. The BXM cards are implemented with Stratm technology which uses a family of custom Application Specific Integrated Circuits (ASICs) to provide high-density, high-speed operation. The three types of BXM cards are:

—The BXM T3/E3 is available as an eight or twelve port card that provides T3/E3 interfaces at 44.736 or 34.368 Mbps rates, respectively. The BXM-T3/E3 can be configured for either trunk or access applications.

—The BXM 155 is available as a four or eight port card that provides OC-3/STM-1 interfaces at 155.52 Mbps rates. The BXM-155 can be configured for either trunk or access applications.

—The BXM 622 is available as a one or two port card that provides OC-12/STM-4 interfaces at 622.08 Mbps rates. The BXM-622 can be configured for either trunk or access applications.

•Enhanced network scaling:

—50/64 trunks per BPX switch equipped with BCC-32 or BCC-64, respectively

—72/144 lines per node equipped with BCC-32 or BCC-64, respectively

—223 routing nodes (with BPX switch or IGX switch)

—trunk based loading

—BCC-3-64 supported on BPX switch

—7000 virtual connections (BCC-3-32)

—12000 virtual connections (BCC-3-64)
