Preface
Congratulations on your purchase of the NETGEAR
™
Model RT210 ISDN router
or the Model RT211 ISDN router. The routers are part of the NETGEAR 200
Series router product family.
The Model RT210 and Model RT211 routers provide connection for one or more
computer workstations to the Internet or to the office over inexpensive ISDN lines.
The routers operate at a speed of up to 512 kilobytes per second (KBps) or 128
KBps without compression, and can download video clips, music, or high-
resolution color graphics from the World Wide Web or other online services many
times faster than a modem. The routers support concurrent data and voice
communications, reducing cost and administration of multiple phone lines.
Purpose
This guide describes the features of both routers and provides instructions on how
to install and configure them.
Audience
To configure and install these products, you should have the following
background and experience:
• Working knowledge of basic network management concepts and terminology
• Working knowledge of tools and procedures for installing and operating
sensitive electronic equipment

Introduction 1-1
Chapter 1
Introduction
This chapter describes the features of the NETGEAR Model RT210 and Model RT211 ISDN
routers and discusses planning considerations for installation.
About the Router
The Model RT210 and Model RT211 routers are remote routers that transport data from one
network to another through wide area connections.
The router compares the network addresses of data packets sent through the LAN to the entries in
its address tables. If a match is found for the destination network, the router passes the packet to
the path indicated by the entry in the routing table.
The entry in the path list contains the ISDN number(s) of the target router. The router sends the
number to the ISDN port for the call to be connected. The path is established and the data is sent to
the remote unit. At the receiving end, the process operates in the reverse order, from the wide area
port to the LAN port.
Features
The Model RT210 and Model RT211 routers are flexible, high performance, easy-to-use routers
that provide a cost effective solution for intelligent networking across an ISDN line. With
minimum setup, you can install and use the routers within minutes to meet a wide variety of
networking requirements.
