DSL-510 ADSL Router User’s Guide

Chapter 1 - Introduction
ADSL modem technology is a relatively new technology and may be unfamiliar to the reader. In this section, we introduce
you to ADSL technology and give a brief description of its key attributes. We also give a general description of the D-Link
DSL-510 ADSL Router and its main features.
What is ADSL?
Asymmetric Digital Subscriber Line (ADSL) is an access technology that utilizes ordinary copper telephone lines to enable
high-speed digital data transmission and interactive multimedia applications for business and residential customers. Using
existing phone lines avoids the need for adding expensive new cable.
ADSL Routers use digital coding techniques that greatly increase the bandwidth capacity of telephone lines without
interfering with regular telephone services. For the ADSL Router user, this means much faster data communications.
ADSL Routers make it possible to enjoy benefits such as high-speed Internet access, telecommuting, collaborative
computing, distance learning, movies on demand and multi-player video gaming without experiencing any loss of quality
or disruption of voice/fax telephone capabilities.
ADSL provides a dedicated service over a single telephone line operating at speeds of up to 8 Mbps downstream (to the
user) and up to 640 Kbps upstream, depending on the type of service and local telephone line conditions. These
conditions are ideal for many user applications. A secure point-topoint connection is established between the user and the
central office of the local telephone company. The user is always connected, thus eliminating dial-up time and simplifying
connectivity issues.
D-Link ADSL devices incorporate the recommendations of the ADSL Forum (
www.adsl.com
) regarding framing, data
format, and upper layer protocols.
