Introduction
This section provides a brief description of the Router, its associated technologies and a list of Router features.
Router Description and Operation
The DSL-G604T ADSL Router is designed to provide a simple, cost-effective and secure ADSL Internet
connection for wired (Ethernet) and wireless (802.11g) stations on your network. The DSL-G604T combines
high-speed ADSL connection technology, TCP/IP routing and 802.11g wireless connectivity in one compact unit.
The Router is easy to install and use. The DSL-G604T connects to an Ethernet LAN via wireless and a standard
Ethernet 10/100 BASE-T interface using RJ-45 connectors. The ADSL connection is made using ordinary
twisted-pair telephone line with standard RJ-11 connectors. This arrangement allows wired and wireless
workstations to share network resources and connect to the Internet using a single WAN interface and IP address.
The Router supports transparent bridging or it can be used for IP packet routing over the Internet. Cost saving
features of the Router such as NAT (Network Address Translator) and DHCP (Dynamic Host Configuration
Protocol) improve efficiency and security. The advanced security enhancements, packet filtering and port
redirection, can help protect your network from potentially devastating intrusions by malicious agents outside
your network.
All the 802.11g wireless settings for the Router are entered on a single page in the web manager. Security for the
wireless interface comes in two forms, WEP Encryption and MAC Address Control.
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.
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 800 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.
