DSL-562T ADSL Router User’s Guide

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-562T ADSL Router is designed to provide a simple and cost-effective ADSL Internet connection for

individual computers through either the Ethernet or USB ports, or use it to bridge your Ethernet LAN to the

Internet. The DSL-562T 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-562T connects to single computer or an Ethernet LAN via a

standard Ethernet interface. A single computer may also be connected through the USB port. 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.
