This device complies with Part 15 of FCC rules. Operation is subject to
the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including
interference that may cause undesired operations.
This equipment has been tested and found to comply with the limits for
a CLASS B digital device pursuant to Part 15 of the FCC Rules. These

iv
limits are designed to provide reasonable protection against harmful
interference in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy, and if not installed and
used in accordance with the instructions, may cause harmful interference
to radio communications.
If this equipment does cause harmful interference to radio/television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and the receiver.
•Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate
the equipment. Shielded RS-232 cables are required to be used to

user to provide and use shielded RS-232 cables.
Information for Canadian Users
The Industry Canada label identifies certified equipment. This
certification means that the equipment meets certain telecommunications
network protective, operation, and safety requirements. The Industry
Canada does not guarantee that the equipment will operate to a user’s
satisfaction.
Before installing this equipment, users should ensure that it is permissible
to be connected to the facilities of the local telecommunications

v
company. The equipment must also be installed using an acceptable
method of connection. In some cases, the company’s inside wiring
associated with a single line individual service may be extended by
means of a certified connector assembly. The customer should be
aware that the compliance with the above conditions may not prevent
degradation of service in some situations.
Repairs to certified equipment should be made by an authorized
Canadian maintenance facility designated by the supplier. Any repairs or
alterations made by the user to this equipment, or equipment
malfunctions, may give the telecommunications company cause to
request the user to disconnect the equipment.
For their own protection, users should ensure that the electrical ground
connections of the power utility, telephone lines, and internal metallic
water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
Caution: Users should not attempt to make such connections
themselves, but should contact the appropriate electrical
inspection authority, or electrician, as appropriate.
This digital apparatus does not exceed the class A limits for radio noise
emissions from digital apparatus set out in the radio interference

Introduction 1
1Introduction
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.

2 Introduction
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 RS-
232 or Telnet connection.
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.

Introduction 3
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.

Before You Begin 7
2Before 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.

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 IDSLline 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.
