4. Um eine Beschädigung des Gerätes zu vermeiden sollten Sie nur Zubehörteile verwenden, die vom Hersteller zugelassen
sind.
5. Das Gerät is vor Feuchtigkeit zu schützen.
6. Bei der Aufstellung des Gerätes ist auf sichern Stand zu achten.  Ein Kippen oder Fallen könnte Verletzungen
hervorrufen. Verwenden Sie nur sichere Standorte und beachten Sie die Aufstellhinweise des Herstellers.
7. Die Belüftungsöffnungen dienen zur Luftzirkulation die das Gerät vor Überhitzung schützt.  Sorgen Sie dafür, daß diese
Öffnungen nicht abgedeckt werden.
8. Beachten Sie beim Anschluß an das Stromnetz die Anschlußwerte.
9. Die Netzanschlußsteckdose muß aus Gründen der elektrischen Sicherheit einen Schutzleiterkontakt haben.
10. Verlegen Sie die Netzanschlußleitung so, daß niemand darüber fallen kann.  Es sollete auch nichts auf der Leitung
abgestellt werden.
11. Alle Hinweise und Warnungen die sich am Geräten befinden sind zu beachten.
12. Wird das Gerät über einen längeren Zeitraum nicht benutzt, sollten Sie es vom Stromnetz trennen.   Somit wird im Falle
einer Überspannung eine Beschädigung vermieden.
13. Durch die Lüftungsöffnungen dürfen niemals Gegenstände oder Flüssigkeiten in das Gerät gelangen.  Dies könnte einen
Brand bzw. Elektrischen Schlag auslösen.
14. Öffnen Sie niemals das Gerät.  Das Gerät darf aus Gründen der elektrischen Sicherheit nur von authorisiertem
Servicepersonal geöffnet werden.

Preface
Thank you for choosing the DSL-500 ADSL Router. The DSL-500 will provide
your private small office or home network with convenient Internet access and
rapid download speeds while improving network efficiency and security. D-Link
strives to provide cost effective broadband access devices that are easy to use and
upgrade for small office and home networks.
If you would like to set up the device quickly in order to verify that the ADSL
connection to the WAN (wide area network) is working properly, please read the
Quick Installation Guide included in the DSL-500 package.
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. 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.
DSL services are provided by many different types of business entities such as
telephone companies, Internet service providers (ISPs), DSL resellers and others.
ADSL service is sometimes bundled together with some form of network service
such as an ISP account. This guide uses the generic terms ADSL service provider
or network service provider to refer to any or all businesses that provide ADSL
service or Internet account services.
Furthermore it is assumed that the reader has some familiarity with Ethernet
networks, networking devices, routing protocols and the TCP/IP suite of
protocols.

Introduction to the Router
This chapter describes the Router and it features and includes an introduction to
ADSL technology. Diagrams are provided detailing the hardware and LED
indicators. A list of package contents is presented at the end of the chapter.
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 private
network. 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 multi-media 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 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.
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. The use of existing copper telephone lines forgoes the need
for upgrading lines 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
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.
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) for PPP connections.
DHCP Support (Dynamic Host Configuration Protocol)
DHCP (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-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 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-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 lets the Router to communicate with all RIP enabled devices.
