Information you will need about your LAN or computer:
Ethernet NIC
If your computer has an Ethernet NIC, you
can connect the DSL-G604T to this Ethernet
port using an Ethernet cable. You can also
use the Ethernet port on the DSL-G604T to
connect to other Ethernet devices, such as a
Wireless Access Point.
Record your info here.
DHCP Client
status
Your DSL-G604T ADSL Router is
configured, by default, to be a DHCP server.
This means that it can assign an IP address,
subnet mask, and a default gateway address
to computers on your LAN. The range of IP
addresses the DSL-G604T will assign are
from
10.1.1.2
to
10.1.1.254
. Your computer
(or computers) needs to be configured to
Obtain an IP address automatically
(that
is, they need to be configured as DHCP
clients.)
It is recommended that your collect and record this information here, or in some other secure place, in
case you have to re-configure your ADSL connection in the future.
Once you have the above information, you are ready to setup and configure your DSL-G604T ADSL
Router.

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.

Web Browser
Any common web browser can be used to configure the Router using the web configuration
management software. The program is designed to work best with more recently released browsers
such as Mozilla, Firefox, Opera, Microsoft Internet Explorer® version 5.0, Netscape Navigator®
version 4.7, or later versions. The web browser must have JavaScript enabled. JavaScript is enabled by
default on many browsers. Make sure JavaScript has not been disabled by other software (such as
virus protection or web user security packages) that may be running on your computer.
Ethernet Port (NIC Adapter)
Any computer that uses the Router must be able to connect to it through the Ethernet port on the
Router. This connection is an Ethernet connection and therefore requires that your computer be
equipped with an Ethernet port as well. Most notebook computers are now sold with an Ethernet port
already installed. Likewise, most fully assembled desktop computers come with an Ethernet NIC
adapter as standard equipment. If your computer does not have an Ethernet port, you must install an
Ethernet NIC adapter before you can use the Router. If you must install an adapter, follow the
installation instructions that come with the Ethernet NIC adapter.
Additional Software
It may be necessary to install software on your computer that enables the computer to access the
Internet. Additional software must be installed if you are using what is called a “bridged” connection.
For a bridged connection, the information needed to make and maintain the Internet connection is
stored on your computer, not in the Router. This type of connection is similar to the arrangement used
for analogue dial-up modems, but the connection speed is much faster. Various terms are to describe a
bridged ADSL connection including the term “RFC 1483 Bridge” which is used in this guide.
About Bridged Ethernet Connections (RFC 1483)
Using this method, the DSL-G604T acts as a transparent bridge, and is invisible to other devices on
both the WAN and LAN side of the bridge. It is therefore necessary to provide some means of
acquiring global IP settings for your account.
All connections to the Internet require a unique global IP address. For bridged connections, the global
IP settings must reside in a TCP/IP enabled device on the LAN side of the bridge, such as a PC, server
or firewall hardware. The IP address can be assigned in a number of ways. Your network service
provider will give you instructions about any additional connection software or NIC configuration that
may be required.
Account Information (User Name and Password)
Most users will need to supply a user name and password used to access the service provider’s
network (and ultimately, the Internet). This information is stored either in the Router’s memory or on
your computer depending on the type of ADSL connection you have.
