DSL-500G ADSL Ethernet Router User’s Guide
Operating System
The DSL-500G 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.
Router vs. Bridge Mode
The DSL-500G can be used in two different mode or roles, a router mode or bridge mode. In bridge mode the
device is intended to connect a single computer to the Internet or WAN (Wide Area Network) interface. In
bridge mode the device is said to be invisible since it does not have an IP address. The IP address is actually
configure on the computer connected to the Ethernet LAN interface. If you are using the device in bridge mode it
is recommended that you run firewall software on the computer connected to it.
Additional Software
It may be necessary to install software on your computer that enables the computer to access the Internet
(through computers operated by your ISP or service provider). 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” which is used in this guide.
If your ADSL service is delivered through a PPP (Point to Point Protocol) or IPoA 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.
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 ADSL connection you have.
ACCOUNT INFORMATION (PPP Connections Only)
User Name:
Password:
Additional PVC Settings
If you are using multiple virtual connections it will be necessary to provide additional VPI and VCI values for
the device. These numbers define a unique route used on the ATM backbone of the WAN. Chapter 5 contains
instruction on how to set up additional PVCs for accounts using more than one virtual connection.
