D-Link DSL-560I User Manual - Introduction

DSL-560I ADSL Router User’s Guide 

Introduction 

This section provides a brief description of the Router, its associated technologies and a list of Router features. 

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. For ADSL services, it is not necessary to use expensive new cabling or 

condition the line in any way. 

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. 

Router Description and Operation 

The DSL-560I 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-560I 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-560I connects to an Ethernet LAN via a standard Ethernet 

100BASE-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.
