D-Link DSL-G664T manual Introduction, Router Description and Operation, What is ADSL?

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-G664T ADSL Router is designed to provide a simple, cost-effective and secure ADSL Internet connection for wired (Ethernet) and wireless (802.11g) stations on your network. The DSL-G664T combines high-speed ADSL connection technology, TCP/IP routing and 802.11g wireless connectivity in one compact unit.

The Router is easy to install and use. The DSL-G664T connects to an Ethernet LAN via wireless and a standard Ethernet 10/100 BASE-T interface using RJ-45 connectors. The ADSL connection is made using ordinary twisted-pair telephone line with standard RJ-11 connectors. This arrangement allows wired and wireless workstations to share network resources and connect to the Internet using a single WAN interface and IP address.

The Router supports transparent bridging or it can be used for IP packet routing over the Internet. Cost saving features of the Router such as NAT (Network Address Translation) and DHCP (Dynamic Host Configuration Protocol) improve efficiency and security. The advanced security enhancements, packet filtering and port redirection, can help protect your network from potentially devastating intrusions by malicious agents outside your network.

All the 802.11g wireless settings for the Router are entered on a single page in the web manager. Security for the wireless interface comes in two forms, WEP Encryption and MAC Address Control.

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 800 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.
