DSL-310 ADSL Modem 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-310 ADSL Modem and its main features.
What is ADSL?
Asymmetric Digital Subscriber Line (ADSL) is an access technology that utilizes ordinary copper
telephone lines to enable broadband 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 modems use digital coding techniques that greatly increase the bandwidth capacity of telephone
lines without interfering with regular telephone services. For the ADSL modem user, this means much
faster data communications. ADSL modems 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.
