Chapter 1Introduction

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.
