Cisco/StrataCom BPX
The Cisco/StrataCom BPX Service Node is a standards-based, multiservice ATM switch
designed to deliver the highest levels of network scalability, flexibility, and efficiency. The BPX
achieves multiservice functionality, efficient use of bandwidth, high performance for all users,
and guaranteed QoS for all traffic types through its advanced traffic-management features.
Advanced traffic-management features, together with an optimized hardware architecture,
allow the switch to simultaneously support ATM, Frame Relay, Internet, voice, wireless
communication, video, switched internetworking, and circuit emulation services.
The BPX also offers operational ease. With the BPX's 20-Gbps capacity of high-throughput,
low-latency switching and support for multiple classes of service, service providers can deliver
innovative revenue-generating data, voice, and video services. The BPX includes high-density
Broadband Switch Module (BXM) cards that provide standard interfaces for connecting to cell-
based customer premises equipment via ATM UNI or to non-Cisco networks via NNI.
The BXM cards support ATM-Frame Relay internetworking and service internetworking. They
also allow you to configure PVCs or SVCs for the following defined service classes:
·
Constant Bit Rate (CBR)
·
Variable Bit Rate-Real-Time (rt-VBR-RT)
·
Variable Bit Rate-Non-Real-Time (nrt-VBR-RT)
·
Unspecified Bit (UBR)
·
Available Bit Rate (ABR)
AXIS Interface Shelf
The AXIS interface shelf lets the BPX Service Node support a wide range of user services.
AXIS modules adapt incoming data to 53-byte ATM cells using industry-standard ATM
adaptation layers (AALs) for transport over the ATM network.
Because the AXIS interface shelf supports a range of services from a single platform,
organizations can reduce equipment costs, fully utilize their investments in existing premises
equipment, and rapidly deploy new services as required.
Services below 34 Mbps are provisioned on the AXIS shelf, and the following interfaces
are supported:
·
Frame Relay
