Caution Cautions alert you to personal safety risk, system damage, or loss of data. Warning Warnings alert you to the risk of severe personal injury. -
Page 14: Additional Safety Information
If the module shows signs of a distinct change in performance. Do not spill food or liquids on the unit. If the unit gets wet, isolate the electrical supply and contact your 3Com reseller. Do not push any objects into the openings of the unit. Doing so can cause fire or electric shock by shorting out internal components. - Page 15 Additional Safety Information This unit contains a lithium battery which is attached to a microchip on the printed circuit board. The defective battery must be disposed of safely in-line with the manufacturers instructions. Interconnecting directly, or by way of other apparatus, to ports complying with SELV requirements may produce hazardous conditions on the network.

Page 17: Bridge /Router Module
RIDGE OUTER ODULE Introduction This chapter outlines the features and uses of the AccessBuilder 7000 Bridge/Router Module when installed in the AccessBuilder 7000 Access Concentrator chassis. There are two versions of the Bridge/Router Module: BRI Bridge Router Module – Connects directly to two Basic Rate ISDN lines (four ISDN channels) and has two WAN ports for connection to leased line services. -
Page 18: Benefits Of Isdn
1: B HAPTER RIDGE OUTER ODULE Typically, the Bridge/Router module is used to interconnect LANs running protocols such as Transmission Control Protocol/Internet Protocol (TCP/IP) or Novell Internetwork Packet Exchange (IPX). The module offers full LAN-to-LAN connectivity at speeds up to 64 Kilobits per second (Kbps) on each ISDN channel (128 Kbps in total) and up to 2 Megabits per second (Mbps) on the WAN port. -
Page 19: Using Isdn To Support Leased Line Wan Circuits
Introduction installation and rental of ISDN lines has dropped to the point where it is extremely attractive as regards cost and performance. Using ISDN to Support Leased Line WAN Circuits ISDN provides an ideal service to connect remote LANs. To be effective, the connecting bandwidth needed is at least 56 Kbps to achieve a realistic throughput. -
Page 20: Principal Features
1: B HAPTER RIDGE OUTER ODULE Principal Features The principal features of the Bridge/Router Module are: Easy to install, configure and support. BRI Bridge/Router Module – 2 x Basic Rate Interface ISDN, 2B+D port, supporting Basic Rate interface of two 64 Kbps channels (or possibly two 56 Kbps channels in the USA) and a 16 Kbps control channel. -
Page 21: Typical Applications
Typical Applications Typical Applications The Bridge/Router module is ideally suited for large central sites providing access for remote users to central site services over ISDN or leased lines. This section describes four of the most common applications of the Bridge/Router module using ISDN. All of these configurations can be carried out using the Quick Configuration option and no further configuration is necessary to make the unit operational. - Page 22 1: B HAPTER RIDGE OUTER ODULE When no data is being passed between the workstation and server, the Bridge/Router Module closes the ISDN connection and the units at each end of the link spoof the Novell IPX protocol so that both the workstation and server believe the connection is still valid.
-
Page 23: Ip Host On The Same Ip Network
Typical Applications IP Host on the Same IP Network If your organization operates a TCP/IP network and needs to extend the IP network over geographically remote sites, it is possible to bridge the network using the Bridge/Router Module. It is only possible to bridge where both sites have the same network address and the devices are on the same subnet. - Page 24 1: B HAPTER RIDGE OUTER ODULE There are some issues about which you should be aware when implementing an IP bridging solution. Although calls to the remote site are only generated when data is addressed to a specific IP host or hosts (in our example, 191.100.100.100), any data that cannot be identified as local is also passed over the link while it is open.
-
Page 25: Ip Host On Another Ip Network
Typical Applications IP Host on Another IP Network Most organizations using TCP/IP protocols on their network, choose to subnet remote sites or even to have them on different networks. This requires that connections to remote sites are routed rather than bridged. The advantage of routing over bridging is that calls to the remote site are only made when data is specifically addressed to a remote network. -
Page 26: Internet Or Ppp Router
1-10 1: B HAPTER RIDGE OUTER ODULE Internet or PPP Router Some small businesses need high-speed connections into the Internet or need to connect to large global networks used by larger organizations. When communicating with another AccessBuilder ISDN bridge/router, the unit uses FastConnect, its own proprietary high speed protocol. -
Page 27: Multiple Connections From A Single Site
Typical Applications 1-11 Multiple Connections from a Single Site In some instances it is likely that you will need to connect to Novell servers on one site, IP hosts on the same remote site or possibly a different remote site and a connection into the Internet. This can all be achieved by running the Quick Configuration several times until all the desired types of connection have been configured. -

NSTALLATION AND PERATION Overview This chapter describes how to install the AccessBuilder 7000 BRI Bridge/Router module and/or the AccessBuilder 7000 PRI Bridge/Router module into the AccessBuilder 7000 Access Concentrator chassis and how to read the LEDs on the module’s front panel. Ensure you read the safety information at the front of this guide before commencing installation of the AccessBuilder 7000 Bridge/Router Module. -
Page 32: Installing The Module
2: I HAPTER NSTALLATION AND PERATION Installing The Module Before installing the module, read the Safety Information at the front of this guide. BRI Bridge/Router Module The AccessBuilder 7000 BRI Bridge/Router Module is a two slot wide module and can be installed in any two adjacent free slots. The single width rear card is installed in the right-most slot of the two slots, when looking at the rear of the AccessBuilder 7000. - Page 33 Installing The Module No connecting cables are supplied with the Bridge/Router Module as standard. Check that you have suitable cables for any connections you want to make to any of the following ports: ISDN port (BRI Bridge/Router Module only). LAN port. WAN port Appendix A for cable pin-outs and types.

Refer to Appendix A for information about the WAN interface cables required. Suitable cables are available from your 3Com reseller as spare parts, refer to Appendix A for the required item part number. -
Page 38: Front Panel Leds
2: I HAPTER NSTALLATION AND PERATION Front Panel LEDs This section describes the Bridge/Router Module’ s LEDs. The LEDs are slightly different for the BRI Bridge/Router Module and the PRI Bridge/Router Module. Most of the LEDs can only be seen when the front door of the chassis is open. -
Page 39: Pri Bridge/Router
Front Panel LEDs PRI Bridge/Router CHAN 1 and 2 Channels 1 and 2 show the status of the two WAN ports, WAN1 and WAN2. When lit, the LED shows that WAN port is configured and up. When flashing, it shows that WAN port is configured and down. ISDN When lit shows that one or more ISDN channels are in use. -
Page 40: Monitoring Isdn Line Usage
2-10 2: I HAPTER NSTALLATION AND PERATION Monitoring ISDN Line Usage After you have first configured the module for use with ISDN, it is important to monitor ISDN line usage to ensure that the unit is working in the way you expect. Check the ISDN and CHANNEL LEDs to ensure that unexpected calls are not being made or that connections are not remaining open when you expect them to have closed. -
Page 41: Setting Up A Wan Link
Setting Up a WAN Link 2-11 Setting Up a WAN Link If you are using the Bridge/Router Module to connect to a remote site over a leased line link, the initial setup is very simple. 1 Before you power on the unit, connect an appropriate WAN cable to the WAN ports on the rear of the unit. - Page 42 2-12 2: I HAPTER NSTALLATION AND PERATION d If you are routing, edit the Port IP address to set it to UNNUMBERED or to a valid IP address for the WAN link. See the AccessBuilder ISDN Access Router Software Reference guide for more information about using numbered and unnumbered links.
