Introduction

Congratulations on your purchase of the ZyXEL Prestige 128
Remote Access Router. The Prestige is the first device to integrate
a Router and Bridge into a single package. In a modem-sized box,
the Prestige offers inexpensive yet complete telecommunications
and internetworking solutions for your home or branch office. 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 Nodes.

Distinguishing features of the Prestige 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 Remote Dial-in User support, an Internet Single User
Account (Network Address Translation), POTS line support (Plain
Old Telephone Service; also called A/B Adapter in Europe),
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 almost any
user.

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 Basic Rate Interface (BRI)

Using either a standard S/T or U Interface (128 uses the S/T
interface and 128U uses the U interface) the Prestige supports a
full range of switch types. The switch type depends on the CO
(Central Office) switch your ISDN line is connected to. See
Chapter 16 for more information on North American, European,
and Asian ISDN firmware and switch types supported by the
Prestige.

The two B-channels can be used independently for two
destinations. Or they can be bundled for one connection to support
bandwidth-on-demand.

Multiple Networking Protocol Support

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

Standar d Phone Ja ck

The Prestige is equipped with two standard phone jacks to connect
to telephones, FAX machines, or modems. This allows the ISDN
line to be used for voice calls as well as data calls.

2 Introduction

Dial On De mand

The Dial On Demand feature allows the Prestige to automatically
place a call to a Remote Node whenever there is traffic coming
from any workstation on the LAN to that remote site.

Bandwidth On Dema nd

The Prestige supports bandwidth up to 128Kbps over a single ISDN
BRI line. It incorporates PPP/MP (Point-to-Point
Protocol/Multilink Protocol) to bundle two B channels over a BRI
line. In addition, the Prestige dynamically allocates bandwidth
between the two B channels, increasing or decreasing speeds as

needed to allow for greater efficiency in data transfer. It supports
BAP (Bandwidth Allocation Protocol) and BACP (Bandwidth
Allocation Control Protocol) to manage the number of links in
multilink bundle.

Full Network Ma nagement

The Prestige incorporates SNMP (Simple Network Management
Protocol) support and menu-driven network management via an
RS-232 or Telnet connection. The Prestige is also equipped with a
Call Detail Record (CDR) to help analyze and manage your
telephone bill.

RADIUS (Remote Authentication Dial In User
Service)

The RADIUS feature allows you to use an external, central, Unix
based server to support thousands of users.

PPP Securit y

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

DHCP Support (Dynamic Host Configuration
Protocol)

DHCP (Dynamic Host Configuration Protocol) allows you to
dynamically and automatically assign IP address settings to hosts
on your network.

Call Control

The Prestige provides budget management for outgoing calls and
maintains a blacklist for unreachable phone numbers in order to
save you the expense of unnecessary charges.

Introduction 3

Data Comp r ession

The Prestige incorporates Stac data compression and CCP
(Compression Control Protocol).

Networking Compatibility

The Prestige is compatible with remote access products from other
companies such as Ascend, Cisco, and 3Com. Furthermore, it
supports Microsoft Windows 95 and Windows NT remote access
capability.

Applications For Your Prestige

Some applications for the Prestige include:

Internet Access

The Prestige supports the TCP/IP protocol, which is the language
used for the Internet. It is also compatible with access servers
manufactured by major vendors such as Cisco and Ascend.

Internet Single User Account (SUA)

4 Introduction

For a small office environment, the Prestige offers a Single User
Internet Account from an ISP (Internet Service Provider). This
allows multiple users on the LAN (Local Area Network) to access
the Internet concurrently for the cost of a single user.

Single User Account address mapping can also be used for LAN to
LAN connection.

M ultiprotocol LAN-to-LAN Connection

The Prestige can dial to or answer calls from another remote access
router connected to a different network. The Prestige supports
TCP/IP, Novell IPX, and has the capability to bridge any Ethernet
protocol.

Telecommuting Server

The Prestige allows Remote Dial-in Users to dial-in and gain access
to your LAN. This feature enables users that have workstations
with remote access capabilities, e.g., Windows 95, to dial in using
an ISDN terminal adapter (TA) to access the network resources
without physically being in the office.

What This Manual Covers

This manual is divided into five parts.

1. Part One - Getting Started (Chapters 1-3) - is structured as a
step-by-step guide to help you connect, install, and setup your
Prestige to operate on your LAN.

2. Part Two - The Internet (Chapter 4) - describes how to
configure the Prestige to connect to the Internet.

3. Part Three - Setting Up Advanced Applications (Chapters 5-

10) - describes how to use the Prestige for more advanced

get through setup and installation of your Prestige as easily as
possible.

10 Before You Begin

Ordering Your ISDN Li ne

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 waits common when ordering a new line. Use the
information in this section to place the order (see Chapter 16 for
information on provisioning your ISDN line). If you have already
installed your ISDN line, you can check the following section to
make sure that you can use all the features of your Prestige.

1. Contact your local telephone company’s ISDN Ordering
Center.

2. Find out what type of ISDN service is available. Refer to
Chapter 16 to find out the provisioning information for the
appropriate switch type and ISDN service. For the U.S., the
Prestige (both U and S/T Interface) have been approved by
Bellcore and have IOC (ISDN Ordering Code) “S” Capability,
EZ-ISDN 1.

3. Provide your telephone company with the proper provisioning
information.

4. When the telephone company installs your ISDN line, be sure
to obtain the following information:

• ISDN switch type.

• ISDN telephone number(s).

• ISDN Service Profile Identifiers (SPID) number(s) (only for

North America).

Collecting General Setup Information

The 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.

Before You Begin 11

• System Name - This is the name given to the 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 IS DN Phone Line Information

After you have successfully installed the ISDN phone line or if you
already have one installed, you need to use the ISDN line
information to complete the worksheet and configure your
Prestige. Your telephone company can give you the following
information to configure the Prestige:

• 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. For North

America, select your ISDN switch type. For DSS1 and 1TR6,
verify this field to make sure that you have the proper firmware
loaded.

• 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
device will use both B channels to communicate. If your
Prestige is sharing the ISDN line with other devices, then
configure B Channel Usage to Switch/Unused.

• Telephone Number(s) - Record on the worksheet the
telephone number(s) given to you by your ISDN provider.
Some switch types only have one telephone number. These
phone numbers should be in a standard digit format (for
example, 5551212). Note that these fields will only accept
digits, so - and spaces will not be accepted.

• 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.

• SPID Number(s) - (For North America only) The SPID
(Service Profile Identifier) is a number used by a central office
switch for identification purposes. With the switch information,
see the previous table for the number of SPIDs you must enter.

You have now collected all of the necessary information about
your ISDN phone line. Make sure that these values are entered into

Before You Begin 13

your worksheet before you continue to the next section. For DSS1
and 1TR6 ISDN, refer to Chapter 3.

Collecting Ether net Setup Informa ti on

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 on the Prestige. 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.

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.

14 Before You Begin

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 as calculated by the Prestige.

IP Subnet Mask Number of Host IDs Number of Bits
