DSL-300 ADSL Ethernet Modem User’s Guide

About This User’s Guide

This user’s guide provides instructions on how to install the DSL-300 ADSL
Modem and use it to connect a PC or Ethernet LAN to the Internet or a remote
LAN. For the sake of simplicity, this document uses the terms Modem (first letter
upper case) to refer specifically to the DSL-300 ADSL Modem, and modem (first
letter lower case) to refer to all such devices including the DSL-300.

This guide assumes that the reader has some familiarity with Ethernet networks,
networking devices, and the TCP/IP suite of protocols.

Before You Start

For the smoothest possible installation process, 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 you begin.

ADSL Service

In order to use the Router you must first have ADSL service establi shed with an
ADSL service provider, usually your local telephone company, or an Internet
service provider (ISP). Contact your local telephone company for information on
the availability of ADSL service in your area.

Micro-filters

Since ADSL and telephone services share the same copper wire to carry their
respective signals, a filtering mechanism may be necessary to avoid mutual
interference. You will need to install a micro-filter (low pass filter) device for each
telephone that shares the line with the ADSL line. Micro-filters are easy to
install in-line devices, which attach to the telephone cable between the telephone
and wall jack. This device will not affect normal telephone services. Your
telephone company or ADSL service provider will have more information
regarding the use and installation of micro-filters.

VPI and VCI Settings

Your ADSL service provider will provide two numbers, a Virtual Path Identifier
(VPI) and a Virtual Channel Identifier (VCI). You will need to enter these two
numbers during the configuration of the Router.

In order to ensure high quality of service and maximum performance, ADSL
technology employs Asynchronous Transfer Mode (ATM) networks (via the
DSLAM). ATM networks use Permanent Virtual Circuits (PVCs) to establish
end-to-end software defined logical connections. The VPI and VCI are contained
in the ATM cell header. These numbers help manage ATM network connections
and identify logical links formed by PVCs.

For convenient reference, you may want to record the VPI and VCI numbers here,
as well as the MAC (Physical) Address of the Modem.

Introduction

ADSL technology is a relatively new technology and may be unfamiliar to the
reader. In this section, we 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-300 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 means there is no need to add
expensive new fiber-optic cable or line conditioning.

ADSL modems greatly increase the signa l carrying capacity of copper telephone
lines without interfering with regular telephone services. For the ADSL user,
this means much faster data communications and interactive multimedia
capabilities. ADSL devices make it possible to enjoy benefits such as high-speed
Internet access, telecommuting (remote LAN access), collaborative computing,
distance learning, movies on demand and multiplayer 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 and up to 640 Kbps upstream, depending on
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 service provider. 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
regarding framing, data format, and upper layer protocols.

Modem Description and Operation

The DSL-300 ADSL Ethernet Modem is easy to install and use. The DSL-300
connects to an Ethernet LAN via a standard Ethernet 10BASE-T interface. Your
ADSL connection is made using ordinary twisted-pair telephone line with
standard RJ-11 connectors. Several PCs can be networked in an Ethernet LAN
and connected to the Internet via the Modem.

Product Features

The DSL-300 ADSL Ethernet Modem utilizes the latest ADSL enhancements and
technologies to provide a reliable Internet portal suitable for most small to
medium sized offices.

G.hs (Auto-handshake)

This feature allows the Modem to use either the G.lite, G.dmt or ANSI T1.413
(Issue 2) ADSL connection standards.

High Performance

Very high data transfer rates can be realized with the Modem. Up to 8 Mbps
downstream bit rate using the G.dmt.

Ethernet Ready

The Modem connects to your Ethernet LAN via a standard 10BASE-T Ethernet
port.

ATM (Asynchronous Transfer Mode)

The DSL-300 supports Bridged Ethernet over ATM (RFC 1483).

Precise ATM Traffic Shaping

Traffic shaping is a method of controlling the flow rate of ATM data cells used to
establish the Quality of Service (QoS) on an ATM network.

Easy Installation

The DSL-300 uses a Windows® based graphical user interface (GUI) for easy
installation and management.

LED Indicators

LED Indicators

The LED Indicators read as follows:

Power Steady green light indicates the unit is powered on.
Status Lights steady green during the ADSL negotiation phase. Once the

connection status has been settled, the light will blink green.
ADSL: Link Steady green light indicates a valid ADSL connection. This will

light after the ADSL negotiation process has been settled.

ADSL: Act Blinking green light indicates an active WAN session.
Ethernet: Link Steady green light indicates a valid Ethernet connection.

Ethernet: Act Blinking green indicates an active Ethernet session.

Unpacking

Open the shipping carton and carefully remove all items. In addition to this
User's Guide, ascertain that you have:

1. DSL-300 ADSL Ethernet Modem

2. DSL-300 tool kit on CD-ROM containing The User’s Guide and the DSL- 300

Configuration Utility software installation program

3. Twisted-pair telephone cable or appropriate connector for ADSL connection

(Use AWG 26 twisted-pair telephone cable where not provided)

Hardware Installation

In this chapter you will learn about the various connections you will need to
make in order to use the Modem.

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.

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. The Test LED should light
for a few seconds and turn off.

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 wall jack.

Connect Ethernet LAN to Modem

The Modem may be connected to any 10BASE-T Ethernet LAN. Any connection
to an Ethernet concentrating device such as a switch or hub must operate at a
speed of 10 Mbps only. Use standard twisted-pair cable with RJ-45 connectors.
The RJ-45 port on the Modem is a crossed (MDI-X) port. Follow standard
Ethernet guidelines when deciding what type of cable to use to make this
connection. You should use a normal straight-through cable when connecting the
Modem to a normal (MDI-X) port on a switch or hub. Use a straight-through
cable when connecting it to an uplink (MDI-X) port on a hub or switch. When
connecting the Modem directly to a PC or server use a straight-through cable. A
valid connection will be indicated by the Ethernet Link LED indicator.

The rules governing Ethernet cable lengths apply to the LAN to Modem
connection. Be sure that the cable connecting the LAN to the Modem does not
exceed 100 meters.
