DSL-500 ADSL Router User’s Guide
About This User’s Guide
This user’s guide provides instructions on how to install the DSL-500 ADSL Router and use it to connect several PCs on an Ethernet LAN (Local Area Network) to the Internet or remote LAN. For the sake of simplicity, this document uses the terms Router (first letter upper case) to refer specifically to the DSL-500 ADSL Router, and router (first letter lower case) to refer to all such devices including the DSL-500.
This guide assumes that the reader is familiar with Ethernet networks, networking devices, routing protocols and the TCP/IP suite of protocols.
Before You Start
This section discusses the various requirements for the successful installation of the Router. In order to avoid difficulties please read and make sure you understand all the prerequisites for proper installation of your new ADSL Router.
Operating Systems
D-Link’s Web-based management software can be used on PCs running Microsoft Windows 95, Windows 98, Windows 98 SE, Windows Me, Windows 2000 and Windows NT.
ADSL Service
In order to use the Router you must first have ADSL service established with 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 must be used 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 will have more information regarding the use and installation of micro-filters.

VPI and VCI Settings
Your Telephone Company 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 Router.
VPI, VCI and MAC Address

VCI _______________ |
MAC Address ______________________________
Global IP Address
Your ISP will supply you with a unique global IP address that you must use if you choose to connect to the ISPs network using the RFC 1483 defined “Bridged Ethernet” encapsulation method. If you use PPPoA to define the connection to your ISP you do not need to assign a global IP address. This is explained further in chapter 3 in the discussion of Connection Method.

Default Gateway IP Address
Some ISPs require the use of a default gateway router. If this is necessary, your telephone company or ISP will provide the IP address of a device to be used for this purpose. Use the space provided below to record the IP address of the ISPs default gateway router.

Introduction
This chapter describes the DSL-500 ADSL Router and its features and gives a brief introduction to ADSL technology.
Router Description and Operation
The DSL-500 ADSL Router is designed to provide a simple, cost-effective and secure ADSL Internet connection for your small to medium sized corporate LAN. The DSL-500 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 multimedia applications such as video conferencing and collaborative computing.
The Router is easy to install and use. The DSL-500 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 PCs can be networked and connected to the Internet. This also allows the creation of a virtual private network for telecommuter access to the LAN and company servers.
The Router can be used for IP packet routing over the WAN and also supports transparent bridging. Other cost saving capabilities of the Router include NAT (Network Address Translator) and DHCP (Dynamic Host Configuration Protocol).
ADSL Technology
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 copper telephone lines forgoes the need for upgrading or adding expensive new cable.
ADSL devices use digital coding techniques that greatly increase the potential capacity of phone lines without interfering with regular telephone services. For the ADSL user, this means much faster data communications and the potential for interactive video 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 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 (to the ISP), depending on local telephone line conditions. These conditions are ideal

DSL-500 ADSL Router User’s Guide
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.
Product Features
The DSL-500 ADSL Router utilizes the latest ADSL enhancements and router technologies to provide a robust Internet gateway suitable for most small to medium sized offices.
PPP (Point-to-Point Protocol) Security
The DSL-500 ADSL Router supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol).
DHCP Support (Dynamic Host Configuration Protocol)
DHCP (Dynamic Host Configuration Protocol) allows IP addresses to be automatically and dynamically assigned to hosts on your network.
Network Address Translation (NAT)
For small office environments, the DSL-500 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 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-500 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-500 supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions will allow the Router to communicate with 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”. This enables you 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).
2
DSL-500 ADSL Router User’s Guide
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 the Router functions as the sole connection to the Internet.
ATM (Asynchronous Transfer Mode)
The DSL-500 supports Bridged Ethernet over ATM (RFC1483), IP over ATM (RFC1577) and PPP over ATM (RFC 2364), and PPP Over Ethernet (RFC 2516).
The Router can support up to eight Virtual Circuit Connections (VCCs).
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 G.dmt.
Full Network Management
The DSL-500 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 feature enables a network manager to access the Router’s management software remotely.
Easy Installation
The DSL-500 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
This chapter discusses the various connections you will need to make in order to use the Router.
When selecting the location for the Router, 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. Also, allow some space above the Router for ventilation to avoid problems with overheating.
It may be convenient for you to place the Router near the PC you intend to use for initial configuration of the Router. For initial configuration of the device, you may need convenient access to the RS-232 serial port on the rear panel. The RS232 serial port is intended for use with text-based console management software for the initial configuration and for out-of-band management of the Router. Whether it is necessary to use an RS-232 console manager for first time set up depends on how you allocate IP addresses on your network. Read Chapter 3, First Time Set Up to help you decide how best to use the Router on your network.
Connect the Power
Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the Router and plug the adapter into a nearby power source. You should see the Power LED indicator light up and remain lit.
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 telephone wall jack. The ADSL cable links the Router to the ISP’s wide area network (including the Internet).
The Router must undergo a negotiation process to establish the terms of 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, it will repeat this process.
Connect Ethernet LAN to Router
The Router may be connected to any 10BASE-T Ethernet LAN. Connection to an Ethernet concentrating device such as a switch or hub should use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a straight-through (MDI-II) connection. Follow standard Ethernet guidelines when
7
DSL-500 ADSL Router User’s Guide
deciding what type of cable to use to make this connection. Use a normal straight-through cable when connecting the Router to a normal (MDI-X) port on a switch or hub. Use a crossover cable when connecting it to an uplink (MDI-II) port on a hub or switch or a cross over converter with a straight through cable. When connecting the Router directly to a PC or server use a crossed cable. A steady green Ethernet Link LED indicator will indicate a valid connection.
The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that the cable connecting the Ethernet LAN to the Router does not exceed 100 meters.
The diagram below illustrates a typical Ethernet LAN to Router connection.
