DSL-504 ADSL Ethernet Router User’s Guide

About This User’s Guide

This user’s guide provides instructions on how to install the DSL-504 ADSL Router and use it to connect a computer or Ethernet LAN 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

Introduction – Describes the Router and its key features. Provides an introduction to ADSL. Lists standards to which the Router complies. Contains a packing list.

Hardware Installation – Discusses how to connect the Router to an Ethernet LAN. Configuring the Router for the First Time – Provides information on how to configure the Router and

establish the WAN connection using the web-based manager. Web-based Configuration – Describes how to use the web-based manager to change Router settings and

configure additional virtual connections (PVCs). Appendix A - Technical Specifications – Lists the technical specifications of the Router, including

standards compliance.

Appendix B - Low Pass Filters – Illustrated examples of how to use low pass filters.

Before You Start

Please read and make sure you understand all the prerequisites for proper installation of your new Router. Have all the necessary information and equipment on hand before beginning the installation.

Installation Overview

The procedure to install the Router can be described in general terms in the following steps:

1. Gather information and equipment needed to install the device. Before you begin the actual installation

make sure you have all the necessary information and equipment. Check the contents of the package to be certain that everything listed on the packing list is included. A packing list is included at the end of this section. The information you will need includes the account name or number and the password used

to gain access to your service provider’s network, and ultimately to the Internet. In addition, some users may be given information used to configure the Router so it can establish a connection to the service provider’s network and the Internet.

2. Install the hardware, that is, connect the Ethernet and telephone cables to the device to establish the

necessary network links to your computer and to the service provider’s network and connect the power adapter to power on the Router.

3. Check the IP settings on your computer and change them if necessary so the computer can access the

web-based software built into the Router. Without the correct IP settings your computer will not be able to communicate with the ddevice or access the software used to configure the Router. Without compatible IP settings on your computer, you will not be able to use a web browser to access the Internet.

4. Use the web-based management software to configure the device to suit the requirements of your ADSL

account as instructed by your service provider. Some users may not need to change any of the device settings that establish and maintain the network connection. It may only be necessary to supply the user name or number and the password used for your account. Other users may not be required to change anything in the Router but they may need to install software on a computer used to access the Internet. Follow the instructions of your service provider to find out what is required for your account.

DSL-504 ADSL Ethernet Router User’s Guide

Requirements

To install and use the Router you need a computer equipped with an Ethernet port (such as an Ethernet NIC) and a web browser. You may also need to use information given to you by your service provider. This information is

stored in the Router’ s memory and used to establish the network connection and confirm your identity. The information may be only your user name (or number) and password, or it may be information used to define your Connection Profile. The connection profile is used to instruct the Router how to communicate with the computers and other routers that are used to control access to the service provider’ s network and ultimately to the Internet. The connection profile is a logical construct that establishes a definite path used for communication and defines the rules or protocols used to initiate and maintain the communication path.

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. Appendix B provides illustrated examples of how to install two common styles of low pass filters.

Operating System

The DSL-504 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 Router using the web configuration management software. The program is designed to work best with more recently released browsers such as 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 Router must be able to connect to it through the Ethernet port on the Router. 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 equipment. If your computer does not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must install an adapter, follow the installation instructions that come with the Ethernet NIC adapter. Normally, an Ethernet port will be TCP/IP enabled, this means that it is able to communicate with other computers on an IP network (such as the Internet). Make sure your computer has the TCP/IP protocol installed. If you have accessed the Internet with the computer before, it already has this installed.

Additional Software

It may be necessary to install software on your computer that enables it to access the Internet. Additional software must be installed if you are using what is called a “bridged” connection. For a bridged connection, the information needed to make and maintain the Internet connection is stored on your computer, not in the Router. This type of connection is similar to the arrangement used for analog dial-up Routers, but the connection speed is much faster. Various terms are to describe a bridged ADSL connection including the term “RFC 1483 Bridge” used in this guide. RFC 1484 is a technical standard used to define a bridged connection.

If your ADSL service is delivered through a PPP (Point to Point Protocol) connection, the information needed to establish and maintain the Internet connection is stored in the Router. In this case, it is not necessary to install software on your computer.

DSL-504 ADSL Ethernet Router User’s Guide

Account Information (User Name and Password)

Most users will need to supply a user name and password used to access the service provider’ s network (and ultimately, the Internet). This information is stored either in the Router’s memory or on your computer depending on the type of connection profile you use.

About Bridged Ethernet Connections (RFC 1483)

Using this method, the DSL-504 acts as a transparent bridge, and is invisible to other devices on both the WAN (wide area network) and LAN (local area network) side of the bridge. It is “ invisible” in the sense that it does not have an IP address associated with it. Every device connected to the WAN must have an IP address to be “ seen” on the network. Devices that connect to the Internet have a “ global” IP address that is unique and is used to identify the device so that it can send and receive data.

All connections to the Internet require a global IP address. It is therefore necessary to provide some means of acquiring global IP settings for your account. For bridged connections, the global IP settings must reside in a TCP/IP enabled device on the LAN side of the bridge, such as a computer, a server or a firewall device. 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.

About 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. Some IPoA connections function like peer-to-peer connections and therefore do not require IP settings on the WAN interface.

Packing List

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

1. One DSL-504 ADSL Ethernet Router

2. One User’s Guide

3. One twisted-pair telephone cable used for ADSL connection

4. One straight-through Ethernet cable

5. One AC power adapter suitable for your electric service

DSL-504 ADSL Router User’s Guide

Introduction

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

Router Description and Operation

The DSL-504 ADSL Router is designed to provide a simple, cost-effective and secure ADSL Internet connection for your small- to medium-sized private network. The DSL-504 combines the benefits of high-speed ADSL connection technology and TCP/IP routing with a conventional Ethernet interface in one compact and convenient package. ADSL connection technology enables many interactive multi-media applications such as video conferencing and collaborative computing.

The Router is easy to install and use. The DSL-504 connects to an Ethernet LAN via a standard Ethernet 10BASE-T interface using RJ-45 connectors. The ADSL connection is made using ordinary twisted-pair telephone line with standard RJ-11 connectors. This arrangement means that several computers can be networked and connected to the Internet using a single WAN interface and IP address.

The Router supports transparent bridging and can be used for IP packet routing over the Internet. Cost saving features of the Router such as NAT (Network Address Translator) and DHCP (Dynamic Host Configuration Protocol) improve administration efficiency and improve security. The advanced security enhancements, packet filtering and port redirection, can help protect your network from potentially devastating intrusions by malicious agents from outside your network.

DSL-504 ADSL Router User’s Guide

Router Features

The DSL-504 ADSL Ethernet Router utilizes the latest ADSL enhancements to provide a reliable Internet portal suitable for most small to medium sized offices. DSL-504 advantages include:

• PPP (Point-to-Point Protocol) Security The DSL-504 ADSL Router 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 network. This eliminates the need to reconfigure every host whenever changes in network topology occur.

• Network Address Translation (NAT) For small office environments, the DSL-504 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-504 supports TCP/IP protocol, the

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

• RIP-1/RIP-2 The DSL-504 supports both RIP-1 and RIP-2 exchanges with other routers. Using both

versions lets the Router to communicate with all RIP enabled devices.

• Static Routing This allows you to select a data path to a particular network destination that will remain in

the routing table and never “ age out”. If you wish to define a specific route that will always be used for data traffic from your LAN to a specific destination within your LAN (for example to another router or a server) or outside your network (to a ISP defined default gateway for instance).

• Default Routing This allows you to choose a default path for incoming data packets for which the

destination address is unknown. This is particularly useful when if the Router functions as the sole connection to the Internet.

• ATM (Asynchronous Transfer Mode) The DSL-504 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 Router 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 Router. Up to 8 Mbps downstream

bit rate using the G.dmt.

• Full Network Management The DSL-504 incorporates SNMP (Simple Network Management Protocol)

support for web-based management and text-based network management via an RS-232 or Telnet connection.

• Telnet Connection The Telnet enables a network manager to access the Router’ s management software

remotely.

• Easy Installation The DSL-504 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 Router.

Hardware Installation

When selecting the location for the Router, be sure to allow room to access the connections on the rear panel. You will want to place the Router so that you will be able to see the LED indicators on the front panel. Allow some space above the Router for ventilation and make sure it is not close to heat sources or appliances that produce a lot of heat to avoid problems from overheating. As with any electrical device, use common sense when choosing a location for the Router.

Connect ADSL Line

Use the twisted-pair ADSL cable (standard telephone cable) included with the Router to connect it to your telephone line. Plug one end of the cable into the ADSL port (RJ-11 receptacle) on the rear panel of the Router and insert the other end into the wall jack. The ADSL connection is the physical connection for the Router’ s

WAN interface. It links the Router to the network service provider’ s backbone infrastructure. This is the Router’ s link to the Internet.

After the Router is powered on it will undergo a negotiation process to establish the ADSL connection. During this negotiation the Status LED will light a steady green, after which it will blink. If the ADSL line is disconnected or the Router restarted, it will repeat this process. If you are required to change the PVC settings (VPI/VCI values), these will need to be changed before the Router can complete a connection to the service provider’ s network through the ADSL connection.

Connect Router to the Ethernet

The Router may be connected to any 10/100BASE-TX Ethernet LAN. 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 Router 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.

Use standard Category 5 or better twisted-pair Ethernet cable with RJ-45 connectors. The RJ-45 ports on the Router are crossed (MDI-X) ports.

The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that any cable connecting a computer or the Ethernet LAN to the Router does not exceed 100 meters.

Computer to Router Connection

You can connect the Router directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a computer or an embedded Ethernet port on a notebook computer or PC using the Ethernet cable provided. The Ethernet cable that come with the Router is known as a straight-through cable. This type of cable is appropriate for connecting to a crossed (MDI-X) port, the kind of port used on common Ethernet adapters for PCs and notebook computers.

If the switch has an available uplink port (MDI-II) you may connect the Router to the uplink port with a straightthrough cable. If the switch has an uplink port and you wish to reserve this for another device, connect to any on the other MDI-X ports (1x, 2x, etc.) with a crossed cable. The easiest way to see if the Ethernet connection is valid is to observe the LED indicators (see Figure 2- 1) when the device is connected and powered on.

Power On Router

To power on the device:

1. Insert the AC Power Adapter cord into the power receptacle located on the rear panel (see Figure 2- 2) of the

Router and plug the adapter into a 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 you have the Router connected to your network you can look at the Ethernet Link/Act LED indicators to

make sure they have valid connections. The Router will attempt to establish the ADSL connection, if the ADSL line is connected and the connection is properly configured (see Chapter 4) this should light up after several seconds.

Configuring the Router for the First Time

The first time you setup the Router it is recommended that you configure the WAN connection using a single computer. If you will use the device for a private network, make sure that the Router is connected only to the single computer and not connected to the LAN. Check the Ethernet connection to the computer by observing the Ethernet Link/Act LED indicator for the connected port.

Once you have the WAN connection functioning properly you may continue to make changes to Router configuration including IP settings and DHCP setup. This chapter is concerned only with using a computer to configure the WAN connection. The following chapter describes the various menus used to configure and monitor the Router including how to change IP settings and DHCP server setup.

Wan Configuration Summary

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

communicate with the Router 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 Router. Your computer can see the Router if it is in the same “ neighborhood” or subnet as the Router. This is accomplished by making sure your computer has IP settings that place it in the same subnet as the Router. The easiest way to make sure your computer has the correct IP settings is to configure it to use the DHCP server in the Router. 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 the 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 should know what Encapsulation and connection type you are required to use for your ADSL service. It is also possible that you must change the PVC settings used for the ADSL connection. Your service provider should provide all the information you need to configure the WAN connection.

Configuring IP Settings on Your Computer

In order to configure your system to receive IP settings from the Router 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 Router. Following this example is a step-by-step description of the procedures used on the other Windows operating systems to first check if the TCP/IP protocol has been installed, if it is not instruction are provided for installing it. Once the protocol has been installed you can configure the system to receive IP settings from the Router.

For computers running non-Windows operating systems, follow the instructions for your OS that configure the system to receive an IP address from the Router, that is, configure the system to be a DHCP client.
