ADSL services are provided by, and sold by a variety of businesses. Your ADSL service
provider may be your telephone company, an Internet service provider (ISP), a business
that specializes in providing network services or a combination of any of these. This
guide uses the generic term, DSL service provider, to refer to any business or agent that
provides DSL service.

BEFORE YOU START
In addition to the Modem hardware and software drivers, you will need some
information before you begin to install the device. Your DSL service provider will give
you the information required for a successful ADSL connection. You will use this
information when you decide which driver to install and configure the Modem. In order
to avoid problems please read this section and make sure you understand all the
prerequisites for proper installation of your new Modem.
Operating Systems
The D-Link DSL-200 can be used with PCs running Microsoft® Windows 98, Windows
98 Second Edition, Windows Millennium Edition , Windows 2000.
USB Port
In addition to the Windows OS, you will need a USB (Universal Serial Bus) type A port
on your computer. These are commonly installed on newer computers, however older
PCs may require an additional installation.
ADSL Service
In order to use the Modem, you must first have ADSL service established with a DSL
service provider.
There are four standards used for ADSL connections known as ANSI T1.413 issue 2,
G.Lite, G.dmt and G.hs. The standards differ somewhat as to data transfer speed or bit
rate. For user convenience, this Modem supports the G.hs Auto-handshake ADSL
standard. This allows the Modem to operate with either type of connection.
Network Protocol and the Software Driver
The protocol used for your ADSL service will determine the particular software driver
to be installed. You will need to select one driver to operate the Modem. Ask your DSL
service provider to assist you in selecting either the LAN (Local Area Network) or WAN
(Wide Area Network) driver to operate the Modem.
Specifically, if your ADSL service uses the protocol defined by RFC 2364, PPP over
ATM Adaptation Layer 5, then you will need to install the WAN driver. If the protocol
used for your ADSL service is defined by RFC 1483, Multiprotocol Encapsulation over
ATM Adaptation Layer 5 (Bridged Ethernet), then you will need to install the LAN
driver.

5
The drivers are fundamentally different in the way they function with the PC. The
PC/Modem relationship can be summarized as follows:
WAN driver – The WAN driver will cause the Modem to appear to the PC as an
ordinary dial-up modem. The Modem employs the Dial-Up Networking software used by
conventional analog modems even though there is no actual dialing or any activity in
the voice band frequencies on the telephone line. This driver supports RFC 2364 PPP
over ATM with PVC connections.
LAN driver - The LAN driver will cause the modem to appear to the PC as a LAN or
Ethernet device. Connection is automatic, similar to a connection to an Ethernet device.
This driver supports RFC 1483 “Bridged Ethernet” with PVC connections. PPP over
Ethernet (RFC 2516) connections are possible with installation of additional client
software.
Microfilters and Splitters
Most ADSL clients will be required to install a simple device that prevents the ADSL
line from interfering with regular telephone services. These devices are commonly
referred to as microfilters or sometimes called (microfilter) line splitters. They are easy
to install and use standard telephone connectors and cable.
Some DSL service providers will send a telecommunications technician to modify the
telephone line, usually at the point where the phone line enters the building. If a
technician has divided or split your telephone line into two separate lines - one for
regular telephone service and the other for ADSL – then you do not need to use any
type of filter device. Follow the instructions given to you by your ADSL service provider
about where and how you should connect the Modem to the ADSL line.
Microfilters
Unless you are instructed to use a “line splitter” (see below), it will be necessary to
install a microfilter (low pass filter) device for each telephone or telephone device
(answering machines, Faxes etc.) that share the line with the ADSL service.
Microfilters are easy-to-install, in-line devices, which attach to the telephone cable
between the telephone and wall jack. Microfilters that install behind the wall plate are
also available. A typical in-line microfilter installation is shown in the diagram on the
next page.

6
Note: Do not install the microfilter between the Modem and the telephone jack.
Microfilters are only intended for use with regular telephones, Fax machines and other
telephone devices.
Line Splitter
If you are instructed to use a “line splitter”, you must install the device between the
Modem and the phone jack. Use standard telephone cable with standard RJ-11
connectors. The splitter has three RJ-11 ports used to connect to the wall jack, the
Modem and if desired, a telephone or telephone device. The connection ports are
typically labeled as follows:
Line - This port connects to the wall jack.
ADSL – This port connects to the Modem.
Phone – This port connects to a telephone or other telephone device.
The diagram below illustrates the proper use of the splitter.

7
Encapsulation Method
It may be necessary to use an encapsulation method that is different from the default
method. The protocol used for your connection, and thus the driver you use will
determine which encapsulation method is used. If your DSL service provider does not
specify which method to use. Use the default encapsulation method.
Modulation Method
It may also be necessary to use a modulation method that is different from the default
method. If your DSL service provider does not specify which method to use. Use the
default modulation method.
Additional Information
WAN Driver Users If you are using the WAN driver, you must supply user account
information (user name and password) to make the final network connection.
LAN Driver Users If you are using the LAN driver, you may be required to manually
configure your IP settings. Your DSL service provider will tell you if you need to
configure your PCs IP settings.

2 INTRODUCTION
ADSL modem technology is a relatively new technology and may be unfamiliar to the
reader. In this section, we will introduce you to ADSL technology and give a brief
description of its key attributes. We also give a general description of the D-Link
DSL-200 ADSL USB Modem and its main 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. Using existing phone lines avoids the need for adding expensive new cable.
ADSL modems use digital coding techniques that greatly increase the bandwidth
capacity of telephone lines without interfering with regular telephone services. For the
ADSL modem user, this means much faster data communications. ADSL modems make
it possible to enjoy benefits such as high-speed Internet access, telecommuting,
collaborative computing, distance learning, movies on demand and multi-player video
gaming 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 (to the user) and up to 640 Kbps upstream, depending on the
type of service and local telephone line conditions. These conditions are ideal for many
user applications. A secure point-to-point connection is established between the user
and the central office of the local telephone company. The user is always connected,
thus eliminating dial-up time and simplifying connectivity issues.
D-Link ADSL devices incorporate the recommendations of the ADSL Forum
(www.adsl.com) regarding framing, data format, and upper layer protocols.

4 SOFTWARE INSTALLATION
The DSL-200 can be used with the following operating systems:
♦Microsoft Windows 98
♦Microsoft Windows 98 Second Edition
♦Microsoft Windows Millennium Edition
♦Microsoft Windows 2000
The procedures for each system are slightly different so follow the instructions provided
for your PC’s operating system.
The Microsoft Plug and Play feature will automatically detect the modem after it has
been installed. A new window will appear for each step of the installation.
Once you have the driver installed and the Modem is connected, you should verify that
the ADSL service is working.
If you wish uninstall the Modem see Appendix B for instructions.
What Driver to Install
You will need to select one driver (see Step 5) to operate the Modem. The driver you use
will depend on the particular protocol used by your ADSL service provider. Ask your
DSL service provider to assist you in selecting either the WAN or LAN driver to operate
the Modem. Only one driver should be installed.
If your ADSL service uses the protocol defined by RFC 2364, PPP over ATM Adaptation
Layer 5, then you will need to install the WAN driver. If the protocol used for your
ADSL service is defined by RFC 1483, Multiprotocol Encapsulation over ATM
Adaptation Layer 5, then you will need to install the LAN driver.

14
Install the Software Driver
You can install the software driver on a PC running either the Windows 98, Windows
98 Second Edition, Windows 2000 or Windows Millennium Edition operating system.
You have a choice of two different drivers, the LAN (Local Area Network) or WAN
(Wide Area Network) driver. The instructions in this chapter can be used for either the
LAN or WAN driver, the installation procedure is identical for both. If you are not sure
which driver you should install, see the previous section What Driver to Install, for more
information.
Install the Driver
Before starting the software setup process, exit all Windows applications currently
opened on your PC. The software driver installation procedure is identical for Windows
98/98SE, Windows Me and Windows 2000.
DO NOT CONNECT THE USB CABLE. You must install the software driver before
you connect the device to your computer via the USB cable. You will be prompted to
connect the device during the installation. Connecting the USB cable at this point will
initiate the Found New Hardware process.
To install the software driver for the Modem, follow these steps:

CONNECT TO THE INTERNET
Now that the driver has been installed you are ready to connect to the Internet by way
of the DSL service provider’s network backbone. Follow the instructions that are
appropriate for the driver you have installed and the operating system of your PC.
If you have installed the WAN driver:
You will use a Dial-Up process that should be familiar to anyone who has installed a
conventional analog modem. The Modem does not actually “dial-up” to establish an
Internet connection, but it uses the same dial-up software as a convenient way to
establish communication.
If you have installed the LAN driver:
Please see the section titled Connect to Internet – LAN Driver Users on page 28.
Dial-Up Connection (WAN Driver Only)
The Procedures for the different operating systems differ slightly so each system is
presented in its own section.
