BPX Switch Network Interface Group

The BPX switch network interface group of cards provides the interface between the BPX switch and the ATM network (see Figure 4-1). The BNI series of cards (DS3, E3, and OC3) are described in this chapter. The BXM card trunk operation is briefly described in this chapter with additional information provided in a later chapter. The BXM cards may be configured for either trunk or service (port UNI) mode. In trunk mode they provide BPX switch network interfaces.

BXM Cards, Trunk Mode Summary

The BXM card sets supports T3/E33, OC-3/STM-1 or OC-12/STM-4 interfaces, and provide the capacity to meet the needs of emerging bandwidth driven applications. The BXM cards provide high speed ATM connectivity, flexibility, and scalability. The card sets are comprised of a front card that provides the processing, management, and switching of ATM traffic and a back card that provides the physical interface for the card set.

A BXM port may be configured to operate as either a trunk or UNI port. The BXM OC-12 back cards support either Single Mode Fiber (SMF) or Single Mode Fiber Long Reach (SMFLR). The BXM OC-3 back cards support either Multi-Mode Fiber (MMF), Single Mode Fiber (SMF), or Single Mode Fiber Long Reach (SMFLR). The BXM-T3/E3 supports T3 1.544 Mbps and E3 34.368 Mbps interfaces.

For a further description of the BXM cards refer to Chapter 6, BXM T3/E3, 155, and 622.
