Router Module Overview 1-3

The base router module consists of a CoreBuilder 5000 14-inch base board with an attached CPU board. Both the base board and the CPU board plug directly into the CoreBuilder 5000 backplane.

The base router module provides four Token Ring backplane connections (complex port connections), any one of which you can connect to any one of 10 CoreBuilder 5000 backplane networks. The Token Ring ports are equivalent to Cisco Systems IOS interface connections.

You can connect only one Token Ring backplane connection to any one CoreBuilder 5000 backplane network.

You can mount any one of multiple standard Cisco Systems Network Interface Module (NIM) types on the base board to provide additional routing connections (Cisco Systems NPM connections) for various protocol types (see Figure 1-1

). Each NIM type requires a unique 3Com

faceplate.

Router Models The router module is available in the following configurations:

Base – Includes 4 Token Ring backplane connections.

FDDI MM, DAS – Multi-mode, dual attachment station/4 Token Ring

backplane connections.

FDDI MM, SAS – Multi-mode, single attachment station/4 Token Ring backplane connections.

FDDI SM, DAS – Single mode, dual attachment station/4 Token Ring backplane connections.

Quad Serial – 4 synchronous serial/4 Token Ring backplane connections.

Router Module Features

FDDI Support The router module provides support for three FDDI configurations on

This section describes the following features of the router module:

■ FDDI Support

■ WAN Support

■ Protocol Translation

■ Scalable Protocol Support

■ WAN Optimization

■ ATM Migration

■ Management Support

■ Distributed, Scalable Reliability

■ Hot Swap Capability

the following two FDDI interfaces:

Multi-Mode Fiber – Can support distances of up to 2 km for both Class A Dual Attachment Stations (DAS) and Class B Single Attachment Stations (SAS).

Single Mode Fiber – Can support distances of up to 10 km for Class A Dual Attachment Stations (DAS).

The FDDI interfaces also include a connector for attachment to an external optical bypass unit. If the router module stops operating, the optical bypass unit ensures that the FDDI signal bypasses that router. The FDDI ring and other stations remain operational.

WAN Support The router module configured with a Quad Serial NIM provides four

synchronous serial ports to support backbone or redundant network connections over the wide area network (WAN). The serial ports support the following connection protocols:

■ V.35

■ EIA-232

■ EIA-449

■ RS-422

■ X.21

Router Module Features 1-7

Each serial port is capable of providing T1/E1 rate connectivity. Each port operates in full duplex mode at speeds from 1,200 bits per second (bps) to 2,048 Megabits per second (Mbps).

You can configure the synchronous serial ports to support IBM

Synchronous Data Link Control (SDLC) traffic using synchronous pass through or Data Link Switching (DLSw).

Protocol Translation The router module protocol translation function allows you to extend

the life of your existing network devices. The router module allows networks operating in dissimilar protocol environments to communicate while managing up to 180 simultaneous sessions.

The router module supports the following bidirectional translations:

■ X.25 to TCP

■ X.25 to Local Area Transport (LAT)

■ X.25 to XRemote devices

■ LAT to TCP

■ LAT to TN3270 devices

Scalable Protocol

Support

Each router module type allows you to select a specific level of protocol support to best match the needs of your application. Four Cisco IOS router software feature sets offer an increasing level of protocol support:

IP/IPX – The base feature set is used in applications requiring only IP/IPX protocols.

Desktop – Provides additional LAN support for use in applications with limited LAN protocol requirements.

Desktop plus IBM – Adds IBM support.

Enterprise – Adds top-level protocol support, including SNA

(Synchronous Network Architecture) integration.

Feature

WAN Optimization The router module provides the following features to help limit network

operating costs by optimizing WAN network connections:

Dial-On-Demand Routing – A more economical alternative to a second leased line as backup, a dial-on-demand backup dials up a second line automatically if the primary WAN link fails.

Data Compression – The router module provides four types of data compression for different network environments:

■ Link compression

■ X.25 packet payload compression

■ TCP/IP header compression

■ DEC

™

LAT compression

ATM Migration The router module can be upgraded to support your migration to an

ATM backbone (see Figure 1-3

Add an ATM network backbone by replacing your original router module NIM, with one of two ATM NIM types:

Management

Support

■ OC-3, MM (Optical Carrier Type 3, Multi-Mode)

■ OC-3, SM (Optical Carrier Type 3, Single Mode)

Each ATM NIM type provides 155 Mbps backbone bandwidth.

The router module is shipped with a comprehensive Management Information Base (MIB) for using Simple Network Management Protocol (SNMP), the industry standard for network management.

You can monitor and control the router module from any SNMP-based management station, including the 3Com Transcend Enterprise Manager.

In addition, the router module is fully compatible with CiscoWorks

network management software from Cisco Systems.

TELNET capability provides for direct access in-band to the agent, and a console port on the module provides for out-of-band management capability.

1-10 CHAPTER 1: INTRODUCTION

Distributed, Scalable

Reliability

The router module operates in the CoreBuilder 5000 Integrated System which is structured to eliminate any single point of failure.

The CoreBuilder 5000 hub provides redundancy for power supplies, switched ports, controller modules, and the hub management module. Automatic switching to the redundant components ensures continuation of the specific function.

3Com fault-tolerant features are fully-scalable, allowing you to implement and alter the degree of fault-tolerance you need as your network grows.

Hot Swap Capability The router module features “hot swap” capability. You can swap the

router module in or out of (install or remove from) a powered-on CoreBuilder 5000 hub.
