About This User’s Guide

This user’s guide provides instructions on how to install the DSL-302G ADSL Modem and use it to connect a

computer (or two computers) to the Internet.

If you are using a computer with a functioning Ethernet port, you can use the Quick Installation Guide to

quickly establish your ADSL connection and access the Internet. If you want to use only the USB port for the

initial connection you will find instructions for USB operation in the section titled “USB Driver”

Terminology

This document uses the terms “Modem” (first letter upper case) to refer specifically to the DSL-302G ADSL

Modem, and “modem” (first letter lower case) to refer to all such devices including the DSL-302G. ADSL

service is provided by different types of businesses including telephone service providers, Internet service

providers and other businesses that provide computer network and telecommunications services. The term

“service provider” is used in this guide to refer to any service that sells or leases DSL services and equipment.

Before You Start

Please read and make sure you understand all the prerequisites for proper installation of your new Modem. Have

all the necessary information and equipment on hand before beginning the installation.

Low Pass Filters

ADSL and telephone services share the same copper wire to carry their respective signals, a filtering mechanism

may be necessary to avoid mutual interference. It may be necessary to install a low pass filter device (also called

micro-filter or splitter) for each telephone that shares the line with the ADSL line. Micro-filters are easy to

install passive devices that connect to the ADSL device and/or telephone using standard telephone cable. Ask

your service provider for more information about the use of low pass filters with your installation.

VPI and VCI Settings

For some installations, it will be necessary to configure certain settings used by the Modem for connection to the

Internet. If your Modem has not already been configured to the specific requirements of your ADSL account,

you will have to change these settings using the Configuration Utility software included with the device.

If necessary, your service provider will provide two numbers, a Virtual Path Identifier (VPI) and a Virtual

Channel Identifier (VCI) that are needed for proper configuration of the Modem. These numbers are used to

manage the service provider’s network infrastructure.

DSL-302G ADSL Ethernet Modem User’s Guide

Introduction

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

Modem Description and Operation

The DSL-302G ADSL Ethernet Modem is easy to install and use. You can use the Modem to connect one

computer using its Ethernet interface, and another computer using the USB interface. The Modem can be

managed through either interface. Once the Modem has been set up, the Ethernet port can be used by any

Ethernet enabled computer to connect to the Internet. To use the USB port, a special device driver must be

installed on any computer connecting to the Modem through the USB interface.

Modem Features

Hardware Installation

This chapter describes the various network cable and power connections required to use the Modem.

Modem Location

When selecting the location for the Modem be sure to allow room to access the connections on the rear panel.

You will want to place the Modem so that you will be able to see the LED indicators on the front panel. Allow

some space above the Modem for ventilation to avoid problems with overheating.

The Modem package includes two feet that can be used to stand the unit on one side if you wish to save space.

Connect the Power

Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the Modem and plug

the adapter into a nearby power source. You should see the Power LED indicator light up and remain lit.

Connect ADSL Line

You can use the twisted-pair telephone ADSL cable included with the Modem to connect to your telephone line.

Simply plug one end of the cable into the ADSL port (RJ-11 receptacle) on the rear panel of the Modem, and

insert the other end into the telephone wall socket or low pass filter, as instructed by your service provider.

Connect Modem to Computer

The Modem may be connected to any Ethernet-ready computer or any computer with a USB port. An Ethernet-

ready computer includes any PC or notebook computer with a working 10Mbps or 100Mbps Ethernet port.

Connect to the Ethernet port with a straight-through Ethernet cable (included). The RJ-45 Ethernet port is an

MDI-X (crossed) port, and can be connected to an MDI-II (straight-through) port, such as an Ethernet port on a

computer, with a straight-through cable. Connecting an MDI-X port to another MDI-X port requires either a

cross-wired cable or a straight-through cable used with a cross-wired adapter.

The rules governing Ethernet cable lengths apply to the computer-to-Modem connection. Be sure that the cable

connecting the computer to the Modem does not exceed 100 meters.

Any computer using the USB port to connect to the Modem requires additional drivers specific to the Modem.

See the instructions in the section titled USB Drivers.
