About this Publication

This publication provides an overview of the operation of the BPX Service Node.

Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more up to date than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription. You can also access Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.

Objectives

This publication is intended to provide reference information useful during installation, configuration, operation, and maintenance of the BPX Service Node.

Audience

This publication is intended for installers, operators, network designers, and system administrators.

Organization

This publication is organized as follows:


Chapter 1	Introduction Describes the overall operation of the BPX Service Node and associated peripherals.
Chapter 2	General Description Provides an overall physical and functional description of the BPX. The physical description includes the BPX enclosure, power, and cooling subsystems. The functional description includes an overview of BPX operation.
Chapter 3	BPX Common Core Describes the common core group, comprising the Broadband Controller Cards (BCCs), the Alarm/Status Monitor (ASM) card, associated backcards, and the StrataBus backplane.
Chapter 4	Network Interface (Trunk) Cards Describes the BPX network interface (trunk) cards, including the Broadband Network Interface (BNI) and associated backcards. The BXM card trunk operation is briefly described in this chapter with additional information provided in Chapter 6.
Chapter 5	Service Interface (Line) Cards This chapter contains a description of the BPX service interface (line) cards, including the ATM Service Interface (ASI) and associated backcards. The BXM card service (port UNI) operation is briefly described in this chapter with additional information provided in Chapter 6.
Chapter 6	BXM T3/E3, 155, and 622 Describes the BXM card group which includes the BXM-T3/E3, BXM-155 and BXM-622 card sets. Describes the operation of these cards in either trunk or service (port UNI) mode.
Chapter 7	ATM Connections Describes how ATM connection services are established by adding ATM connections between ATM service interface ports in the network using ATM standard UNI 3.1 and Traffic Management 4.0. It describes BXM and ASI card operation and summarizes ATM connection parameter configuration.
Chapter 8	Configuration and Management Provides preliminary configuration overview for configuring a BPX Service Node and an AXIS.
Chapter 9	Repair and Replacement Describes periodic maintenance procedures, troubleshooting procedures, and the replacement of major BPX components.
Chapter 10	Frame Relay to ATM Network and Service Interworking Describes frame relay to ATM interworking which allows users to retain their existing Frame Relay services, and as their needs expand, migrate to the higher bandwidth capabilities provided by BPX ATM networks. Frame Relay to ATM Interworking enables frame relay traffic to be connected across high-speed ATM trunks using ATM standard Network and Service Interworking.
Chapter 11	Tiered Networks Describes the tiered network configuration that provides the capability of adding interface shelves/feeders (non-routing nodes) to an IPX/IGX/BPX routing network.
Chapter 12	BPX SNMP Agent Introduces the functions of the Simple Network Management Protocol (SNMP) agent and MIBs that are embedded in each BPX node.
Appendix A	BPX Node Specifications Lists the BPX Service Node specifications.
Appendix B	BPX Cabling Summary Provides details on the cabling required to install the BPX Service Node.
Appendix C	BPX Peripherals Specifications Provide details on the specifications for peripherals used with the BPX Service Node.
Appendix D	AT3-6ME Interface Adapter Describes the AT3-6M Interface Adapter, sometimes referred to as the T3-T2 Interface Adapter, that may be used with the BPX Service Node to provide a 6 Mbps ATM network interface to T2 transmission facilities.
