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

Preface
About Your Router/Hub
Congratulations on your purchase of the Prestige 128MH PSTN Router/Hub.
The Prestige 128MH 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 regular phone lines, or PSTN (Public
Switched Telephone Network).
The Prestige 128MH supports multi-protocol routing for TCP/IP and Novell IPX, as well as
transparent bridging for other protocols. With the built-in 4-port Ethernet 10Base-T hub, you get
the added benefit of eliminating the clutter caused by an external hub.
Your Prestige 128MH is easy to install and to configure since you do not need to set any switch.
All functions of the Prestige 128MH 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 manual shows you how to configure and manage your router.
This manual consists of fourteen chapters and is designed to guide you through the configuration
of your Prestige 128MH for the various applications.

Prestige 128MH PSTN Router/Hub
xx Preface
Structure of this Manual
This manual is divided into five parts:
Step 1. Getting Started (Chapters 1-2) is structured as a step-by-step guide to help you
connect, install and setup your Prestige 128MH to operate on your network.
Step 2. The Internet (Chapter 3) describes how to configure your Prestige 128MH for
Internet access.
Step 3. Setting Up Advanced Applications (Chapters 4-8) 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.
Step 4. Management & Maintenance (Chapters 9-13) provides information on
management and maintenance facilities for network administrators.
Step 5. Troubleshooting (Chapter 14), provides information about solving common
problems.
Regardless of your particular application, it is important that you follow the steps outlined in
Chapters 1-2to connect your Prestige 128MH to your LAN. You can then refer to the appropriate
chapters of the manual, depending on your applications.
Syntax Conventions
For brevity’s sake, we will use “e.g.” as a shorthand for “for instance”, and “i.e.” for “that is” or
