Introduction

This section provides a brief description of the Router, its associated technologies and a list of Router
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. For ADSL services, it is not necessary to install
expensive new cabling or condition the line in any way.
ADSL greatly increases the signal carrying capacity of copper telephone lines without interfering with
regular telephone services. For the ADSL user, this means faster downloads and more reliable
connectivity. ADSL devices make it possible to enjoy benefits such as high-speed Internet access
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 and up to 640 Kbps upstream, depending on local telephone line conditions. A secure
point-to-point connection is established between the user and the central office of the service provider.
D-Link ADSL devices incorporate the recommendations of the ADSL Forum regarding framing, data
format, and upper layer protocols.

Router Description and Operation

The DSL-G604T ADSL Router is designed to provide a simple, cost-effective and secure ADSL
Internet connection for your small- to medium-sized private network. The DSL-G604T combines the
benefits of high-speed ADSL connection technology and TCP/IP routing with a conventional Ethernet
interface in one compact and convenient package. ADSL connection technology enables many
interactive multi-media applications such as video conferencing and collaborative computing.
The Router is easy to install and use. The DSL-G604T connects to an Ethernet LAN via a standard
Ethernet 10BASE-T interface using RJ-45 connectors. The ADSL connection is made using ordinary
twisted-pair telephone line with standard RJ-11 connectors. This arrangement means that several PCs
can be networked and connected to the Internet using a single WAN interface and IP address.
Low Pass Filters
Since ADSL and telephone services share the same copper wiring to carry their respective signals, a
filtering mechanism may be necessary to avoid mutual interference. A low pass filter device can be
installed for each telephone that shares the line with the ADSL line. These filters are easy to install
passive devices that connect to the ADSL device and/or telephone using standard telephone cable. Ask
your service provider for more information about the use of low pass filters with your installation.
Appendix B provides illustrated examples of how to install two common styles of low pass filters.
Operating Systems
The DSL-G604T uses an HTML-based web interface for setup and management. The web
configuration manager may be accessed using any operating system capable of running web browser
software, including Windows 98 SE, Windows ME, Windows 2000, and Windows XP.
