Introduction

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

Modem Description and Operation

The DSL-360T ADSL Modem is designed to provide a simple and cost-effective ADSL Internet connection for
a single computer through the Ethernet port; or use it to bridge your Ethern et LAN to the Internet. The DSL­360T combines the benefits of high-speed ADSL technology and LAN IP management in one compact and
convenient package. ADSL technology enables many interactive multi-media applications such as video
conferencing and collaborative computing.

The Modem is easy to install and use. The DSL-360T connects to single computer or an Ethernet LAN via a
standard Ethernet interface. The ADSL connection is made using ordinary twisted-pair telephone line with
standard connectors. Multiple PCs can be networked and connected to the Internet using a single Wide Area
Network interface and single global IP address.

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.

ADSL greatly increases the signal carrying capacity of copper telephone lines witho ut 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 co nnection
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.

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 can be installed for each
telephone that shares the line with the ADSL line. These 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.

Operating Systems

The DSL-360T 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, including Windows 98
SE, Windows ME, Windows 2000, and Windows XP.

1

DSL-360T ADSL Modem User’s Guide

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 more recently released browsers such as Opera, Microsoft
Internet Explorer® version 5.0, Netscape Navigator® version 4.7, or later versions. The web browser must have
JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not been
disabled by other software (such as virus protection or web user security packages) that may be running on your
computer.

Ethernet Port (NIC Adapter)

Any computer that uses the Modem must be able to connect to it through the Ethernet port on the Modem. This
connection is an Ethernet connection and therefore requires that your computer be equipped with an Ethernet
port as well. Most notebook computers are now sold with an Ethernet port already installed. Likewise, most fully
assembled desktop computers come with an Ethernet NIC adapter as standard equ ipment. If your computer does
not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Modem. If you must
install an adapter, follow the installation instructions that come with the Ethernet NIC ad apter.

Additional Software

It may be necessary to install software on your computer that enables the computer to access the Internet.
Additional software must be installed if you are using the device a simple bridge. For a bridged connection, the
information needed to make and maintain the Internet connection is stored on another computer or gateway
device, not in the Modem itself.

If your ADSL service is delivered through a PPPoE, PPPoA or IPoA connection, the information needed to
establish and maintain the Internet connection can be stored in the Mode m. In this case, it is not necessary to
install software on your computer. It may however be necessary to change some settings in the device, including
account information used to identify and verify the connection.

All connections to the Internet require a unique global IP address. For bridged co nnections, th e global IP settings
must reside in a TCP/IP enabled device on the LAN side of the bridge, such as a PC, a server, a gateway device
such as a router or similar firewall hardware. The IP address can be assigned in a number of ways. Your network
service provider will give you instructions about any additional connection software or NIC configuration that
may be required.

Modem Features

The DSL-360T ADSL Modem utilizes the latest ADSL enhancements to provide a reliable Internet portal
suitable for most small to medium sized offices. DSL-360T advantages include:

• PPP (Point-to-Point Protocol) Security – The DSL-360T ADSL Modem supports PAP (Password

Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) for PPP connections.

• DHCP Support – Dynamic Host Configuration Protocol automatically and dynamically assigns al LAN IP

settings to each host on your n etwork. Th is eliminates the need to reconfigure ever y host when ever ch anges
in network topology occur.

• Network Address Translation (NAT) – For small office environments, the DSL-360T allows multiple

users on the LAN to access the Internet concurrently through a single Internet account. This provides
Internet access to everyone in the office for the price of a single user.

NAT improves network security in effect by hiding the private network behind one global and visible IP
address. NAT address mapping can also be used to link two IP domains via a LAN-to-LAN connection.

• TCP/IP (Transfer Control Protocol/Internet Protocol) – The DSL-360T supports TCP/IP protocol, the

language used for the Internet. It is compatible with access servers manufactured by major vendors.

• ATM (Asynchronous Transfer Mode) – The DSL-360T supports Bridged Ethernet over ATM (RFC1483),

IP over ATM (RFC1577) and PPP over ATM (RFC 2364).

• Precise ATM Traffic Shaping – Traffic shaping is a method of controlling the flow rate of ATM data cells.

This function helps to establish the Quality of Service for ATM data transfer.

• G.hs (Auto-handshake) – This allows the Modem to automatically choose either the G.lite or G.dmt ADSL

connection standards.

• High Performance – Very high rates of data transfer are possible with the Modem. Up to eight Mbps

downstream bit rate using the G.dmt.

• Easy Installation – The DSL-360T uses a web-based graphical user interface program for convenient

management access and easy set up. Any common web browser software can be used to manage the Modem.

Hardware Installation

The DSL-360T maintains two interfaces and provides a bridge between two networks. An Ethernet port connects
to a computer or Ethern et LAN and an ADSL port provides the connectio n to the Internet and the Wide Area
Network. Place the Modem in a location where it can be connected to the various devices as well as to a power
source. The Modem should not be located where it will be exposed to moisture or excessive heat. Mak e sure the
cables and power cord are placed safely out of the way so they do not create a tripping hazard. As with any
electrical appliance, observe common sense safety procedures.

The access point can be placed on a shelf or desktop, ideally you should be able to see the LED indicators on the
front if you need to view them for troubleshooting.

Power on Modem

CAUTION: The Modem must be used with the power adapter included with the

device.

To power on the Modem:

1. Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the Modem and
plug the adapter into a suitable nearby power source.

2. You should see the Power LED indicator light up and remain lit. The Status LED should light solid green
and begin to blink after a few seconds.

3. If the Ethernet port is connected to a working device, check the Ethernet Link/Act LED indicators to make
sure the connection is valid. The Modem will attempt to establish the ADSL connection, if the ADSL line is
connected and the Modem is properly configured this should light up after several seconds. If this is the first
time installing the device, some settings may need to be changed before the Modem can establish a
connection.

Factory Reset Button

The Modem may be reset to the original factory default settings by depressing the reset button for a few second s
while the device is powered on. Use a ballpoint or paperclip to gently push down the reset button. Remember
that this will wipe out any settings stored in flash memory including user account information and LAN IP
settings. The factory default IP address of the Modem is 192.168.1 .1 and the subnet mask is 255.255.255.0 , the
default management Username is admin and the default Password is admin.

DSL-360T ADSL Modem User’s Guide

Network Connections

Network connections are provided through the ADSL port and the Ethernet port on the back of the Modem. See
the Rear Panel diagram above and the illustrations below for examples.

Connect ADSL Line

Use the ADSL cable included with the Modem to connect it to a telephone wall socket or receptacle. 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 RJ-11 wall socket. If you are using a low pass filter device, follow the instructions included with the
device or given to you by your service provider. The ADSL connection represents the WAN interface, the
connection to the Internet. It is the physical link to the service provider’s network backbone and ulti mately to the
Internet.

Connect Modem to Ethernet

The Modem may be connected to a single computer or Ethernet device through the 10BASE-TX Ethernet port
on the rear panel. Any connection to an Ethernet concentrating device such as a switch or hub must operate at a
speed of 10/100 Mbps only. When connecting the Modem to any Ethernet device that is capable of operating at
speeds higher than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the connecting port.

Note

Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Modem is a crossed port (MDI-X).
Follow standard Ethernet guidelines when deciding what type of cable to use to make this connection. When
connecting the Modem directly to a PC or server use a normal straight-through cable. You should use a crossed
cable when connecting the Modem to a normal (MDI-X) port on a switch or hub. Use a normal straight-through
cable when connecting it to an uplink (MDI-II) port on a hub or switch.

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.

In order to connect the Modem to an Ethernet LAN, it is necessary to install
3rd-party PPP connection software on any system used to access the Internet.

Computer to Modem Connection

Connect the Modem
directly to a
10/100BASE-TX

Configuring the Modem for the First Time

The first time you setup the Modem, configure the WAN connection using a single computer connected directly
to the Modem. Once the WAN connection is functioning properly, you may continue to make changes to Modem
configuration including IP settings and DHCP setup. This chapter is concerned with using your computer to
configure the WAN connection. The following chapter describes the various menus used to configure and
monitor the Modem including how to change IP settings and DHCP server setup.

Wan Configuration Summary

1. Connect to the Modem To configure the WAN connection used by the Modem it is first necessary to

communicate with the Modem through its management interface, which is HTML-based and can be
accessed using a web browser. To access the management software your computer must be able to
“see” the Modem. Your computer can see the Modem if it is in the same “neighborhood” or subnet as
the Modem. This is accomplished by making sure your computer has IP settings that place it in the
same subnet as the Modem. The easiest way to make sure your computer has the correct IP settings is to
configure it to use the embedded DHCP server in the Modem. The next section describes how to change
the IP configuration for a computer running a Windows operating system to be a DHCP client.

2. Configure the WAN Connection Once your are able to access the configuration software you can

proceed to change the settings required to establish th e ADSL connection and connect to the service
provider’s network. There are different methods used to establish the connection to the service
provider’s network and ultimately to the Internet. You shou ld know what Encapsulation and conn ection
type you are required to use for your ADSL service. For some users, it may be necessary to change the
PVC settings used for the ADSL connection. Your service provider should provide all the information
you need to successfully configure the WAN connection.

Configuring IP Settings on Your Computer

In order to configure your system to receive IP settings from the Modem it must first have the TCP/IP protocol
installed. If you have an Ethernet port on your computer, it probably already has TCP/IP protocol installed. If
you are using Windows XP the TCP/IP is enabled by default for standard installations. Below is an illustrated
example of how to configure a Windows XP system to automatically obtain IP settings from the Modem.
