About This User’s Guide
This user’s guide instructs the reader to install the DSL-300G+ ADSL Modem and use it to connect a sing le computer 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.
Guide Overview
Chapter 1 Introduction – A description of the Modem and its key features including Front and
Rear panel diagrams. A packing list is included at the end of the chapter. Chapter 2 Hardware Installation – A description of alternatives for connecting the Modem to a
single computer or to an Ethernet Local Area Network (LAN). Chapter 3 First Time Set Up – A step-by-step guide for configuring the Modem to communicate
with a computer and establish the ADSL connection. Chapter 4 Using the Web Manager – An illustrated description of the various management
functions used for configuring and monitoring the Modem. Management software is web-based and can be accessed using a standard web browser.
Appendix A Technical Specifications – A list of hardware and software specifications including standards and protocols compliance.
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
Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering mechanism may be necessary to avoid mutual interference. A low pass filter device (also called micro-filter or splitter) can be installed 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.
Requirements for Installation
You will need a computer that meets the minimum requirements listed below to set up and use the Modem. In addition, it will be necessary to configure the device using information provided by your ADSL service provider or ISP. This information is used to establish the parameters of the ADSL connection and identify the Modem on the service provider’s network.
Operating System Requirements
The DSL-300G+ uses an HTML-based web interface for setup and management. The web configuration manager may be accessed using any operating system capable of running web browser software.
Web Browser
Any common web browser can be used to configure the Modem using the web configuration management software. The program is designed to work best with Microsoft Internet Explorer® version 5.0, Netscape Navigator® version 4.7, or later versions. The web browser must have Javascript enabled. Make sure Javascript has not been disabled system wide by other software (such as virus protection or web user security packages).

DSL-300 ADSL Ethernet Modem User’s Guide
Ethernet Adapter (NIC)
Any computer using the Modem for Internet access, must have an Ethernet NIC (Network Interface Card) installed or a working Ethernet port. Most recently produced notebook computers are equipped with an Ethernet port. The system must have TCP/IP Protocol installed and enabled. If you have an Ethernet port installed, you probably already have TCP/IP enabled.
The Modem is equipped with a DHCP server to automatically assign an IP address to computer using it. The computer must first be configured to receive this IP address from the Modem. Instruction for configuring Windows operating systems to become a “DHCP client” is provided in the section titled First Time Set Up.
If you are using the Modem as a simple bridge (RFC 1483), additional software may be needed for the computer or server connected to the Modem (on the LAN side). Your ADSL service provider or ISP will give you more information.
Connection Type
There are different methods available to make the connection from your computer (through the Modem) to the Internet (through your ADSL service). In order to properly configure th e Modem, it is necessary to know what connection type is used to provide your ADSL connection.
The Modem supports the following connection types:
PPP over ATM (RFC 2364) used by default PPP over Ethernet (RFC 2516) IP over ATM (RFC 1577) Ethernet over ATM (RFC 1483)
Account Information (User Name and Password)
A User Name and Password used to identify your account on the service provider’s network. For PPPoE and PPPoA connections, the account information is stored in the Modem’s memory. If your connection uses Ethernet over ATM (RFC 1483) it is likely that you will also need a user name and password. For RFC 1483 connections however, the account information is actually stored on your co mputer along with connection sof tware you must install on your system.
ACCOUNT INFORMATION User Name: Password:
Bridged Ethernet Connections (RFC 1483)
All connections to the Internet require a unique global IP address. For bridged co nnections, th e global IP settings must reside in your computer. Your ADSL service provider or ISP may have given you a CD with software that you must install on computer. Ask you service provider for more information.
viii
DSL-300 ADSL Ethernet Modem User’s Guide
IPoA Connections (RFC 1577)
IP over ATM connections may require global IP settings for the device. Your service provider will give you IP settings information if needed.
Global IP Settings for IPoA Connections IP Address: Netmask: Gateway: DNS:
Additional Settings
If your ISP or ADSL service provider has instructed to change the VPI/VCI settings, there is a special menu, the System Settings menu in the management software used to change this. Some accounts using PPPoE may be instructed to change the AC Name. The AC Name is changed in the same menu. See the section titled Using the Web Manager for instructions on changing these settings.

Introduction
This section provides a brief description of the Modem, its associated technologies and a list of Modem features.
ADSL Technology
Asymmetric Digital Subscriber Line (ADSL) is broadband access technology that provides high-speed digital data transmission and interactive multimedia applications for business and residential customers over ordinary telephone line.
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 enable high-speed Internet access without any loss of quality or disruption of telephone services.
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. 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-300G+ ADSL Modem is designed to provide a simple, cost-effective and secure ADSL Internet connection for your small to medium-sized private network. The ADSL connection technology enables many interactive multi-media applications such as video conferencing and collaborative computing.
The Modem is easy to install and use. The DSL-300G+ connects to an Ethernet LAN or single computer via a standard Ethernet interface. The ADSL connection is made using ordinary twisted-pair telephone line with standard RJ-11 connectors.
Modem Features
The DSL-300G+ ADSL Ethernet Modem utilizes the latest ADSL enhancements to provide a reliable Internet portal suitable for most small to medium sized offices. DSL-300G+ advantages include:
Quick and easy installation with a user friendl y web - based GUI for configuration and management
Built-in DHCP server
High data transfer rates; up to 8 Mbps downstream and up to 640 Kbps upstream
DSLAM interoperability; the auto-detect function automatically selects the correct connection type
during the initialization process
MIB Support; built-in MIBs allow some SNMP management functions
Bridged Ethernet over ATM support; the DSL-300 G+ supports RFC 2684 (also RFC 1483)
Firmware can be upgraded using TFTP
