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 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.

Note

This digital apparatus does not exceed the class A limits for radio noise emissions from digital apparatus set
out in the radio interference regulations of Industry Canada.

Preface

Congratulations on your purchase of the Prestige 202H ISDN router.

About This User's Manual

This manual is designed to guide you through the configuration of your Prestige for its various applications.
This manual may refer to the Prestige 202H ISDN router as the Prestige.

You may use the System Management Terminal (SMT), web configurator or

command interpreter interface to configure your Prestige. Not all features can be

configured through all interfaces. This User's Guide primarily shows SMT

configuration but includes the other interfaces where appropriate.

Getting Started

This part is structured as a step-by-step guide to help you connect, install and setup your router to

operate on your network and access the Internet.

Prestige 202H User’s Guide

Chapter 1

Getting to Know Your Prestige

This chapter covers the key features and main applications of your router.

1.1 Introducing the Prestige 202H

The Prestige 202H is a high-performance router that offers a complete Internet Access solution.

By integrating NAT, firewall, VPN capability and a four-port switch, the Prestige 202H is a complete
security solution that protects your Intranet and efficiently manages data traffic on your network.

The embedded web configurator is easy to operate and totally independent of your operating system
platform. You can also manage the router via the SMT (System Management Terminal), a menu-driven
interface that you can access from either a terminal emulator or telnet.

1.2 Features

This section describes the router’s key features.

IPSec VPN Capability

Establish Virtual Private Network (VPN) tunnels to connect (home) office computers to your company
network using data encryption and the Internet; thus providing secure communications without the expense
of leased site-to-site lines. The router’s VPN is based on the IPSec standard and is fully interoperable with
other IPSec-based VPN products.

Firewall

The Prestige has a stateful inspection firewall with DoS (Denial of Service) protection. By default, when the
firewall is activated, all incoming traffic from the WAN to the LAN is blocked unless it is initiated from the
LAN. The Prestige firewall supports TCP/UDP inspection, DoS detection and protection, real time alerts,
reports and logs.

4-Port Switch

A combination of switch and router makes your router a cost-effective and viable network solution. You can
connect up to four computers to the router without the cost of a hub. Use a hub to add more than four
computers to your LAN.

Getting to Know Your Prestige 1-1

Prestige 202H User’s Guide

Auto-negotiating 10/100 Mbps Ethernet LAN

The LAN interfaces automatically detect if they are on a 10 or a 100 Mbps Ethernet.

Auto-crossover 10/100 Mbps Ethernet LAN

The LAN interfaces automatically adjust to either a crossover or straight-through Ethernet cable.

Call Scheduling

Configure call time periods to restrict and allow access for users on remote nodes.

Network Address Translation (NAT)

NAT (Network Address Translation - NAT, RFC 1631) allows the translation of multiple IP addresses used
within one network to different IP addresses known within another network.

SNMP (Simple Network Management Protocol – Versions 1 and 2)

SNMP, a member of the TCP/IP protocol suite, allows you to exchange management information between
network devices. Your router supports SNMP agent functionality that allows a manager station to manage
and monitor the router through the network.

SNMP is only available if TCP/IP is configured on your router.

IP Alias

IP Alias allows you to partition a physical network into logical networks over the same Ethernet interface.
The Prestige supports three logical LAN interfaces via its single physical Ethernet LAN interface with the
Prestige itself as the gateway for each LAN network.

ISDN Data Link Connections

The router supports two types of ISDN Data Link Connections: point-to-multipoint and point-to-point.

ISDN Basic Rate Interface (BRI) Support

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

Incoming Call Support

In addition to making outgoing calls, you can configure the router to act as a remote access server for
telecommuting employees.
