Introduction
Definitions
Before you install or use your new modem, 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. The 6210 is a bridge.
A router is a device that forwards messages according to their network
addresses. The 6211 can be configured as a bridge or a router.
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”).
Both the 6210 and 6211 contain an ADSL2+ modem, so they often are referred to
as modems in this manual.
