1 Introduction

Congratulations on your purchase of the ZyXEL Prestige 128L IDSL
Router. The Prestige integrates a Router and Bridge, offering
inexpensive yet complete telecommunications and internetworking
solutions for your home or branch office. The Prestige is ideal for
everything from Internet access, to receiving calls from Remote Dial-in
Users, to making LAN-to-LAN connections to Remote Nodes.

Distinguishing features of the Prestige 128L include support for a full
range of networking protocols such as TCP/IP (Transmission Control
Protocol/Internet Protocol), Novell IPX (Internet Packet Exchange),
and Transparent Bridging. The complete solution also includes extensive
Network Management, and solid security features.

Features

The Prestige is packed with a number of features that give it the
flexibility to provide a complete networking solution for Internet access
and business users.

Ease of Installation

The Prestige is a self-contained unit that is quick and easy to install.
Physically, it resembles an external modem except for the fact that it is a
router and uses an Ethernet cable to connect to the host network.

Introduction 1

ISDN Digital Subscriber Line (IDSL)

IDSL uses the 2B1Q line coding standard for ISDN BRI circuits. Used
for data-only applications, IDSL can use unshielded twisted pair wire
for transmitting data at 64/128Kbps for up to 18,000 feet.

The differences between IDSL and ISDN are:

1. ISDN passes through the phone company's central office voice
network; IDSL bypasses it by plugging into a special router at the
phone company end. Or a pair of Prestige 128L’s can be
connected by a single twisted pair cable.

2. ISDN requires call setup; IDSL is a dedicated service.

Multiple Networking Protocol Support

The Prestige 128L is a multi-protocol router. It supports TCP/IP,
Novell IPX and Transparent Bridging.

Full Network Management

The Prestige 128L incorporates SNMP (Simple Network Management
Protocol ) support and menu-driven network management via an RS­232 or Telnet connection.

2 Introduction

PPP Security

The Prestige 128L supports PAP (Password Authentication Protocol)
and CHAP (Challenge Handshake Authentication Protocol ).

Dynamic Host Configuration Protocol (DHCP)

DHCP allows you to dynamically and automatically assign IP address
settings to hosts on your network.

Data Compression

The Prestige incorporates Stac data compression and Compression
Control Protocol.

Applications For Your Prestige

Some applications for your Prestige include:

Internet Access

The Prestige supports TCP/IP protocol. It is also compatible with other
IDSL access servers manufactured by vendors such as Ascend.

Internet Single User Account (SUA)

For a small office environment, the Prestige SUA support. This allows
multiple users to access the LAN simultaneously using a single IP
address.

SUA address mapping can also be used for LAN to LAN connections.

Multiprotocol LAN-to-LAN Connection

The Prestige 128L can connect to another Prestige 128L-like router to
link two different LANs. The Prestige 128L supports TCP/IP and
Novell IPX routing, and has the capability to bridge any Ethernet
protocol.

Introduction 5

6 Introduction

2 Before You Begin

To ensure successful installation of your Prestige, we strongly
recommend that you carefully follow the steps outlined in Chapters 2
and 3. These chapters are designed as a guide for you to collect all
necessary information about your LAN. Once this information has been
collected, it will be used to configure your Prestige.

After you have successfully configured your Prestige, see the
appropriate chapters to setup your application.

Road Map and Flow

The chart below is provided as a step by step guide to successful
installation your Prestige.

Before You Begin 7

Figure 2-1 Installation Guide

Completing the Worksheet

Before you continue, locate the worksheet at the end of this chapter.
This information worksheet has been provided to help you get through
setup and installation of your Prestige as easily as possible.

Ordering Your IDSL Line

There is no need to order an IDSL line if you are using a pair of
Prestige 128Ls directly connected by a twisted pair cable. If you
choose to use IDSL, you will need to contact your local telephone
company and order IDSL leased service to connect two IDSL routers.

8 Before You Begin

Collecting General Setup Information

Your Prestige requires the following 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.

• System Name - This is the name given to your Prestige for
identification purposes. This name should be no more than 8
alphanumeric characters. Spaces are not allowed, but “-” and “_”
are accepted. This name can be obtained remotely via the SNMP
management protocol and will be displayed as the prompt when the
user enters the Command Mode.

• Route IP Field - For Internet access, you will need to enable the
Route IP Field. See Chapter 4 for more details on configuring your
Prestige for Internet access. To support Novell IPX, or Bridging,
enable the appropriate protocol and reference the related chapters
for detailed information.

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

Collecting IDSL Information

• Service Type - There are two options: Client or Server. One
IDSL router should be set as the client, and the other as server.

• Transfer Type - There are two options: Leased 128 or Leased

64. The data will be transmitted in 128Kbps if Leased128 is
selected; otherwise, it will be transmitted in 64Kbps. The transfer
type must be set the same for both the client and server router.

Before You Begin 9

Collecting Ethernet Setup Information

This section assumes that you are setting up your Prestige for a TCP/IP
connection. If you want to configure the Prestige for other protocols
(e.g., IPX), refer to the appropriate chapters.

• Ethernet Interface - The first step is to determine the type of
Ethernet interface you will be using. There are two options: AUI or
UTP. Record the interface type onto the worksheet. If you have a
10Base2 (BNC), you should choose AUI.

• 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.,

192.68.203.5.

Record the IP Address into the worksheet as assigned by your

network administrator. Note that every machine on an internet must
have a unique IP address - do not assign an arbitrary address to
any machine.

• IP Sub-net 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 will
automatically calculate this mask based on the IP address that you
assign. Unless you have special need for subnetting, use the default
mask.

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.

This chapter outlines how to connect your Prestige to the LAN and
IDSL line. Refer to the diagram below to identify all of the ports on
your device when you attempt to make the various connections.

Figure 3-1 Rear Panel Diagram

A Warning On Connection Cables

The IDSL line and Ethernet cable, are very similar to each other. It is
important that you use the correct cable for each connection; otherwise,
your Prestige could be damaged.

Installation 15

Connecting Your Computer and Your Prestige

For the initial setup of your Prestige, use the provided RS-232 cable
and communications software to configure your Prestige.

After your Prestige has been successfully installed, you can modify the
configuration through a remote Telnet connection. See Chapter 12 for
detailed instructions on using Telnet to configure your Prestige.

Connecting the RS-232 Cable to your Prestige

One 9-25 pin adapter is included with your Prestige. To connect a RS­232 cable, connect the 9-pin end of the cable to the DTE port on the
back panel of the Prestige. Connect the other end to the RS-232 cable
connected to the serial port (COM1, COM2, or any other COM port)
of your computer.

Connecting an IDSL Line to your Prestige

Plug one end of the IDSL line included in your package into the socket
on the rear panel of your Prestige labeled Line, and the other end into
the IDSL wall jack or another Prestige.

O NOTE: THE IDSL JACK IS FOR IDSL LINE CONNECTION ONLY. CONNECTION OF A

PHONE LINE MAY RESULT IN DAMAGE TO YOUR PRESTIGE.

ATTENTION: LA FICHE IDSL EST DESTINÉE UNIQUEMENT POUR LA CONNEXION SUR UNE

LIGNE RNIS. LA CONNEXION SUR UNE LIGNE TÉLÉPHONIQUE PEUT
ENDOMMAGER VOTRE ADAPTATEUR DE TERMINAL.

Connecting an Ethernet Cable to your Prestige

Your Prestige supports two types of Ethernet connections. The
connection procedure differs for each one; follow the one that is
appropriate for your installation.

UTP

16 Installation

The UTP port is used to connect to a 10Base-T network. 10Base-T
networks use Unshielded Twisted Pair (UTP) cable and RJ-45
connectors that look like a bigger telephone plug with 8 pins. Two types
of gray Ethernet cables come with the package:

• Straight through cable (white tag): Connect your Prestige 128L

to a 10Base-T hub.

• Crossover cable (red tag): Connect your Prestige to your

computer directly without a hub.

O NOTE: IF THIS CABLE IS USED TO CONNECT IDSL, IT MAY DAMAGE YOUR PRESTIGE.

AUI
The AUI port (the connector with 15 pins) is used to connect your

Prestige to a 10Base5 (thicknet) network.
If you have a 10Base2 network using BNC connectors and thin coaxial

cables, you will need a transceiver between the AUI port and the
10Base2 cabling.

Connecting the Power Adapter to your
Prestige

Plug the 16VAC 1000mA power adapter into the outlet on the rear
panel of the Prestige labeled POWER.

At this point, you should have connected the RS-232 cable, the ISDN
phone line, the Ethernet cable, and the power supply. You can now
power on your Prestige.
