BPX Switch Service Interface Group Summary

The BPX switch service interface group of cards provides an ATM interface between the BPX switch and CPE (see Figure 5-1). The ASI series of cards (DS3, E3, and OC3) are described in this chapter. The BXM card service 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 port (service access UNI) mode. In service (port UNI) mode they provide ATM service interfaces to CPE.

BXM Cards, Port (UNI) Mode Summary

The BXM card sets supports OC-12/STM-4 or OC-3/STM-1 interfaces, and provide the capacity to meet the needs of emerging bandwidth driven applications. The BXM provides 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 of a back card that provides the physical interface for the card set.
