1 GETTING STARTED

Introduction

This chapter contains all the information you need to install and configure the AccessBuilder 500 to make it operational. You can carry out more sophisticated configuration using the information in the AccessBuilder ISDN Access Router Software Reference guide.

AccessBuilder 500 Features

The AccessBuilder 500 is a remote local area network (LAN) ISDN access router, which allows geographically separate LAN workgroups and single small office users, to connect to central computing facilities through either, a dial-up on demand connection over the integrated services digital network (ISDN), or a permanently connected leased line.

The AccessBuilder 500 is designed to connect a LAN (Local Area Network) at one location with a number of other LANs at remote locations. The LAN could comprise any number of PCs, servers or other computing equipment, which in an office or small business environment are typically linked together using a centrally located Ethernet hub. In order to interconnect the LANs in different locations, the AccessBuilder 500 unit transmits information over a WAN (Wide Area Network) service provided by telephone carrier organizations.

1-2 CHAPTER 1: GETTING STARTED

The most modern and efficient of these WAN services includes ISDN (Integrated Services Digital Network). This provides a high speed dialup facility to allow your AccessBuilder 500 to automatically and quickly dial remote offices, transmit your data between remote PCs just as speedily and then disconnect the call. You incur minimum ISDN telephone charges as calls are made only when needed. This is known as Dial on Demand.

ISDN can also be used to make voice calls using the AccessBuilder 500’s Voice port. You can connect an ordinary telephone handset, faxes and other similar office equipment.

The AccessBuilder 500 also has al port for connection over a permanent leased line WAN connection, also available from your telephone carrier organization. Leased lines are available to work at a range of speeds which incur higher costs the higher the line speed. The benefit of leased lines is their permanence and fixed cost. No dialling is required but unlike ISDN you pay a fixed cost regardless of whether you transfer little data or high volumes of data 24 hours a day.

Overall ISDN is probably the most cost effective solution for small businesses. However, if your requirements to move data between sites is likely to increase, the flexibility offered by the AccessBuilder 500 fitted with both ISDN and WAN ports allows you to choose the type of connection between sites that best meets your needs.

Typically, the AccessBuilder 500 is used to interconnect LANs running protocols such as Transmission Control Protocol/Internet Protocol (TCP/IP) or Novell Internetwork Packet Exchange (IPX). Offering full LAN-to-LAN connectivity at speeds up to 64 Kilobits per second (Kbps) on each ISDN B channel (128 Kpbs in total) and up to 2 Megabits per second (Mbps) on the WAN port, the AccessBuilder 500 is a compact desktop unit with unrivalled price and performance.

In the USA, some ISDN services run over 56 Kbps channels. Basic Rate ISDN therefore offers connectivity of 112 Kbps in total.

Introduction 1-3

The principal features of the AccessBuilder 500 are:

■Easy to install, configure and support.

■ISDN, 2B+D port, supporting Basic Rate interface of two 64 Kbps and a 16 Kbps control channel.

■Voice port.

■Leased line wide area network (WAN) access port.

■Data terminal equipment (DTE) management port.

■Support for full IP and IPX routing.

■Protocol transparent bridging.

■Sophisticated data packet filtering to provide network security.

■Provides NetWare protocol spoofing.

■Data compression based on an optimized Lempel Ziv algorithm.

■Remote and local management.

■Flash erasable programmable read-only memory (EPROM), allowing the remote upgrading of the units operating system.

■Uses simple network management protocol (SNMP) and provides management information base (MIB) II support.

1-4 CHAPTER 1: GETTING STARTED

Benefits of ISDN

ISDN is an extension of the national and international public switched telephone network, which offers a digital end-to-end telecommunication system, providing a better quality service than available using the analog telephone network. The principal benefits of ISDN are:

■Fast call setup times, typically taking less than one second for national calls.

■Greater bandwidth with multiple channels.

The basic rate service, often referred to as ISDN 2, carries two 64 Kbps (or possibly two 56 Kpbs in USA) user channels, called B channels and one 16 Kbps control channel called the D channel. The line service is presented into the customers premises through a standard RJ45 socket.

A significant aspect of the ISDN service is that it can be provided over the same wiring that was installed for the original telephone service. Therefore, ISDN can be made available relatively cheaply almost anywhere that previously had access to the analog system.

The cost of installation and rental of basic rate ISDN lines has dropped to the point where it is extremely attractive as regards cost and performance.

Introduction 1-5

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. Slower speed links can be used but usually only when usage is low and infrequent, or if higher speed circuits cannot be provided.

Leased digital point-to-point circuits can still be cost effective if usage spans many hours per day. However as ISDN tariffs reduce, this balance also changes. ISDN can be used to provide effective backup of these point-to-point WAN circuits in two ways.

■Firstly, if the point-to-point circuit fails, an ISDN channel can be dialled-up automatically and quickly, to provide an alternative path to the remote unit.

■Secondly, if the leased circuit becomes heavily loaded due to peaks in the traffic between remote bridges or routers, additional bandwidth can be automatically dialled-up to supplement the bandwidth of the leased circuit. The interconnected bridges would then treat the leased line and ISDN channel as parallel links, sharing the load across the two.
