DSL-302G ADSL Ethernet Modem User’s Guide

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 Co nfiguration 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.

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

The DSL-302G ADSL Ethernet Modem utilizes the latest ADSL enhancements and technologies to provide a
reliable Internet portal suitable for most small to medium sized offices.

• Flexible Connectivity Choose either the USB port or the Fast Ethernet port to connect

• Multiple User Support Both port can be used simultaneously to connect two computers

• Plug and Play USB Installation The USB driver installs automatically

• Bridged Ethernet over ATM Support The DSL-302G supports RFC 1483

• Installation Wizard The easy-to-use configuration utility connects you quickly

• Auto-detect Function The device complies with the most common standards used for ADSL

connection and automatically selects the correct connection type during the initialization process

• MIB Support Built-in MIBs allow SNMP management functions

Front Panel

Place the Modem in a location that allows a view of the LED indicators. To save space you can use the feet to
stand the device on either its right or left side.

Front Panel

Rear Panel

All cable connections to the Modem are made at the rear panel. The factory reset button is located here as well.
