Introduction

Router Description and Operation
The DSL-504T ADSL Router is designed to provide a simple and cost-effective ADSL
Internet connection for individual computers through the Ethernet ports, or use it to
bridge your Ethernet LAN to the Internet. The DSL-504T combines the benefits of
high-speed ADSL technology and LAN IP management in one compact and convenient
package. ADSL technology enables many interactive multi-media applications such
as video conferencing and collaborative computing.
The Router is easy to install and use. The DSL-504T connects to computers or an
Ethernet LAN via a standard Ethernet interface. The ADSL connection is made using
ordinary twisted-pair telephone line with standard connectors. Multiple PCs can be
networked and connected to the Internet using a single Wide Area Network (WAN)
interface and single global IP address.
The Router supports transparent bridging and 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 administration efficiency
and improve security for your private network. The advanced security enhancements,
packet filtering and port redirection, can help protect your network from potentially
devastating intrusions by malicious agents from outside your network.
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 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.
