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-500 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-500 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-500 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.

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. 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. The use of existing copper telephone lines forgoes the need

for upgrading lines 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),

collaborative computing, distance learning, movies on demand and multi-player
