Introduction to the Router

This chapter describes the Router and it features and includes an introduction to
ADSL technology. Diagrams are provided detailing the hardware and LED
indicators. A list of package contents is presented at the end of the chapter.

Router Description and Operation

The DSL-504 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-504 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-504 connects to an Ethernet LAN
via four standard 10/100 Mbps Ethernet interfaces 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.
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 network security. 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.

ADSL Technology

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 copper telephone lines forgoes the need for
upgrading or adding expensive new cable.
ADSL devices use digital coding techniques that greatly increase the potential
capacity of phone lines without interfering with regular telephone services. For
the ADSL user, this means much faster data communications and the potential
for interactive video capabilities. ADSL devices make it possible to enjoy benefits
such as high-speed Internet access, telecommuting (remote LAN access),
