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)
