Introduction

Definitions

Before you install or use your new router, you may find it helpful to understand the
following terms:
A bridge is a device that forwards any message from one part of a network to
another.
A router is a device that forwards messages according to their network
addresses.
ADSL is Asymmetric Digital Subscriber Line, a version of DSL that allows a
higher speed for information coming from the Internet to your PC
(“downstream”) than it does for information going to the Internet from your PC
(“upstream”).
The Model 6218 is a Digital Subscriber Line (DSL) modem that may be set by you
to run in bridge or router mode. Because it is most frequently used as a router, that
is how it is referred to in this manual.
