Preface

About Your Router

Congratulations on your purchase of the Prestige 128

Router.

The Prestige 128+ is a high-performance bridge/router that offers a complete
solution for your WAN (Wide Area Network) applications such as Internet
access, multi-protocol LAN-to-LAN connections, telecommuting and remote
access over ISDN (Integrated Service Digital Network).

The Prestige 128+ supports multi-protocol routing for TCP/IP and Novell IPX, as
well as transparent bridging for other protocols. Your Prestige 128+ is easy to
install and to configure since you do not need to set any switches.

The Prestige Web Configurator (PWC) is a JAVA based utility designed that
allows users to manage the Prestige via a Worldwide Web browser.
functions of the Prestige 128+ are software configurable via the SMT (System
Management Terminal) Interface. The SMT is a menu-driven interface that you
can access from either a VT100 compatible terminal or a terminal emulation
program on a PC.

About This User's Manual

This user's guide shows you how to configure and manage your router.

Plus

(Prestige 128+) ISDN

Moreover, all

It is designed to guide you through the configuration of your Prestige 128+ for its
various applications.

Ordering an ISDN Line

Preface xxi

Prestige 128+ ISDN Router

If you do not have the ISDN line installed already, we suggest that you order it
from your telephone company as soon as possible to avoid the long wait
commonly encountered when ordering a new line.

To order a new ISDN line, do the following:

1. Contact your local telephone company’s ISDN Ordering Center to find out what

type of ISDN service is available and the switch type.

2. Provide your telephone company with the line provisioning information for that

switch type, which can be found in the Appendix of this manual. This insures

proper operation of all of the Prestige’s features with the ISDN line.

3. When the telephone company installs your ISDN line, please be sure to obtain

and write down the following information for future use:

• ISDN switch type

• ISDN telephone number(s)

Completing the Setup Information Worksheet

Before you continue, locate the worksheet in the Appendix . This information
worksheet has been provided to help you collect the necessary information
needed for setup and installation in the following chapters.

Collecting General Setup Information

The Prestige requires certain system information. You can obtain all the pertinent
information from your network administrator. Record this information into the
worksheet as it becomes available. This worksheet will later be referred to as you
configure your Prestige.

xxii Preface

Prestige 128+ ISDN Router

System Name - This is the name given to the Prestige for identification purposes.
This name should be no more than eight alphanumeric characters. Spaces are not
allowed, but ‘-’ and ‘_’ are accepted.

You have now collected all of the general setup information you need. Please
make sure that you have entered all the values onto the worksheet before
proceeding to the next section.

Collecting ISDN Phone Line Information

Once your ISDN line is installed by the telephone company, you need to use the
following information to complete the worksheet and configure your Prestige.
Much of this information is provided by your telephone company upon
installation of the ISDN line.

Switch Type - This is the type of switch used by your telephone company.
Check with your telephone company and choose the appropriate option on the
worksheet.

B Channel Usage - Determine which connection is appropriate for your B
channel and check the corresponding option on the worksheet. If your Prestige is
the only device using the ISDN line, then configure B Channel Usage to
Switch/Switch so that your Prestige will use both B channels to communicate.
If your Prestige is sharing the ISDN line with other devices, then configure B
Channel to Switch/Unused.

Telephone Number(s) - Record on the worksheet the telephone number(s) given
to you by your telephone company. Some switch types only have one telephone
number. The Prestige only accept digits; ‘-’ and spaces are not allowed.

Analog Call - Check the appropriate Analog Call option on the worksheet for
each telephone number. This information is later used to configure the Prestige in
routing an incoming analog call. Set to Phone1 or Phone2 if you wish to route
the incoming analog call for this telephone number to PHONE port number 1 or

2.

Preface xxiii

Prestige 128+ ISDN Router

Supplemental Service Activation Keys – Sometimes called ‘buttons,’ most of
the supplemental services supported by the Prestige require that an activation key
be set before a feature can be used.

You have now collected all of the necessary information about your ISDN
telephone line. Make sure that these values are entered into your ‘Setup
Information Worksheet’ before you continue to the next section.

Collecting Ethernet Setup Information

IP Address - An IP Address is required for TCP/IP protocol. The IP Address is

the unique 32-bit number assigned to your Prestige. This address is written in
dotted decimal notation (four 8-bit numbers, between 0 and 255, separated by
periods), e.g., 192.168.1.1.

Record the IP Address into the worksheet as assigned by your network
administrator. Please note that every machine on an internet must have a unique
IP address - do not assign an arbitrary address to any machine. If you are not
sure as to which IP address to assign to the Prestige, contact your LAN
administrator or refer to Chapter 4 of this guide for more details.

IP Subnet Mask - This field is required for TCP/IP protocol. An IP address
consists of two parts, the network ID and the host ID. The IP Subnet Mask is
used to specify the network ID portion of the address, expressed in dotted
decimal notation. The Prestige automatically calculates this mask based on the IP
address that you assign. Unless you have special need for subnetting, use the
default mask as calculated by the Prestige.

The table below lists some examples of IP subnet masks and the number of hosts
that are allowed. Consult your network administrator if you are unsure of this
value.

1. Getting Started (Chapters 1-2) is structured as a step-by-step guide to help

you connect, install and setup your Prestige to operate on your network.

2. The Internet (Chapter 3) describes how to configure your Prestige for

Internet access.

3. Setting Up Advanced Applications (Chapters 4-10) describes how to use

your Prestige for more advanced applications such as LAN-to-LAN
connectivity for TCP/IP and Novell IPX, and transparent bridging for other
protocols.

4. Management & Maintenance (Chapters 11-15) provides information on

management and maintenance facilities.

5. Troubleshooting (Chapter 16), provides information about solving

common problems.

Regardless of your particular application, it is important that you follow the steps
outlined in Chapters 1-2 to connect your Prestige to your LAN. You can then

Chapter 1

Getting to Know Your Router

This chapter describes the key features and applications of your Prestige.

1.1 Prestige 128+ ISDN Bridge Router

The Prestige 128+ is an ISDN bridge/router. The Prestige is ideal for everything
from Internet browsing to receiving calls from remote dial-in users to making
LAN-to-LAN connections to remote networks.

1.2 Features of Prestige 128+

The following are the key features of the Prestige 128+.

L2TP Support

The L2TP protocol allows users to build their own private “tunnel” through the
Internet to enable transport of non-IP traffic (e.g., IPX). Rather than making a
long-distance call to the corporate server, a telecommuter or branch office can
use a local ISP and the Internet to connect to a corporate network.

ISDN Basic Rate Interface (BRI) Support

The P128+ supports a single BRI. A BRI offers two 64Kbps channels, which can
be used independently for two destinations or be bundled to speed up data
transfer.

Extensive Analog Phone Support

The Prestige is equipped with two standard phone jacks for you to connect analog
devices such as telephones and FAX machines. It also supports supplementary
services such as call waiting and 3-way conferencing.

Ethernet Port

The P128+ offers a choice of 10Base-T or AUI Ethernet port connections.

Single User Account (SUA)

The SUA™ (Single User Account) features allows multiple users to share a
single user account.

Incoming Call Support

In addition to making outgoing calls, the Prestige allows you to configure it as a
remote access server for telecommuting employees.

Multiple Protocol Support

♦ TCP/IP (Transmission Control Protocol/Internet Protocol) network layer

protocol.

♦ Novel IPX (Internetwork Packet eXchange) network layer protocol.

♦ Transparently bridging for unsupported network layer protocols.

♦ PPP/MP (Point-to-Point Protocol/Multilink Protocol) link layer protocol.

Dial-On-Demand

The Dial-On-Demand feature allows the Prestige to automatically place a call to
a remote gateway based on the triggering packet’s destination without user
intervention.

PPP Multilink

The Prestige can bundle multiple links in a single connection using PPP
Multilink Protocol (MP). The number of links can be either statically configured
or dynamically managed based on traffic demand.

Bandwidth-On-Demand

The Prestige dynamically allocates bandwidth by dialing and dropping
connections according to traffic demand.

Full Network Management

♦ SNMP (Simple Network Management Protocol) support.

♦ Accessing SMT (System Management Terminal) through telnet connection.

♦ Web-based PWC (Prestige Web Configurator).

Logging and Tracing

♦ CDR (Call Detail Record) to help to analyze and manage the telephone bill.

♦ Built-in message logging and packet tracing.

♦ Unix syslog facility support.

RADIUS Support

RADIUS (Remote Authentication Dial-In User Service) is the most popular
protocol for user authentication on dial-up lines. RADIUS support allows you to
use an external server for unlimited number of users and the ease of centralized
management.

PAP and CHAP Security

The Prestige supports PAP (Password Authentication Protocol) and CHAP
(Challenge Handshake Authentication Protocol). CHAP is more secure than
PAP; however, PAP is readily available on more platforms.
