BRIDGED ETHERNET CONNECTIONS (RFC 1483)
For Bridged Ethernet connections it will be necessary to give the Router a global
IP address and default gateway.
Global IP Address
If the connection method used is Ethernet over ATM (RFC 1483), a unique global
IP address will be needed for the Router. The assigned global IP address must be
entered only if
 the connection method used is Ethernet over ATM (RFC 1483).
When using the default connection method, PPP over Ethernet (RFC 2516), a
global IP address will be assigned automatically during the connection process.
Default Gateway IP Address
Some network service providers require that a default gateway router be used by
the Router to connect to their network backbone. If this is the case, the IP
address of the default gateway (router) must be entered during the configuration
of the device.
BRIDGED ETHERNET CONNECTIONS
Global IP Address:                    ______ : ______ : ______ : ______
Default Gateway IP Address:   ______ : ______ : ______ : ______
DNS SETTINGS
Your DSL service provider should give you DNS settings. These settings should
include the IP address of the DNS server as well as its domain name. You must
enter these in the DHCP Configuration menu.

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 locate 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 RS-232
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 4, 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. Simply 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 WAN interface. It links
the Router to the network service provider’s backbone infrastructure. This is the
Router’s access point to 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

28
straight-through (MDI-X) connection. Follow standard Ethernet guidelines when
deciding what type of cable to use to make this connection. Use a normal crossed
cable when connecting the Router to a normal (MDI-X) port on a switch or hub.
Use a straight-through cable when connecting it to an uplink (MDI-II) port on a
hub or switch. When connecting the Router directly to a PC or server (MDI-II)
use a straight-through cable. A valid connection will be indicated by a steady
green Ethernet Link LED indicator.
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.

Connect Server or PC to Router
The Router may be connected directly to a server or PC using the RJ-45 Ethernet
port. The diagram below illustrates a PC/Server to Router connection with the
Router being employed as a firewall.

First Time Set Up
It will be convenient for most users to establish an initial ADSL connection for
one PC equipped with an Ethernet NIC (Network Interface Card). It is
recommended that you install and configure the Router using one non-networked
computer. This allows you to verify that the ADSL service is functioning and that
you are able to communicate with the device. Once the initial ADSL connection is
established, you can proceed to build an Ethernet LAN around the device or
incorporate it into an existing LAN. For convenience, the PC used to configure
the Router is henceforth referred to as the manager PC.
To further simplify things it is recommended that you use the Router’s web-based
management software for initial configuration. To communicate with the Router,
the manager PC must be connected to it via an Ethernet connection and have a
web browser installed. Furthermore, the manager PC must reside within the
same subnet as the Router. This can be done easily using the DHCP function of
the Router. The Router will act as a DHCP server by default. You can configure
the manager PC to obtain its IP settings from the Router by following the
procedure in the next section.
You should start by configuring the manager PC to obtain IP settings from the
Router. Next disconnect the manager PC from the network and connect it directly
to the Router with a straight-through Ethernet cable.
If you do not wish to change the existing IP settings of the manager PC, you can
change the IP address of the Router. For instructions for changing the Router’s
IP address read Chapter 6, LAN Setup
, for more information.

Access the Web-based Manager
The Manager PC can now use a web browser to communicate with the Router. Be
sure that the Manager PC is not configured to use a proxy server for Internet
access.
Note:Be sure that the Manager PC is not configured to use a proxy server in the Internet
settings. In Windows Internet Explorer, you can check if a proxy server is enabled using the
following procedure:
1. In Windows, click on the 
START button, go to 
Settings and choose 
Control Panel.
2. In the Control Panel window, double-click on the 
Internet Options icon.
3. Click the 
Connections tab and click on the 
LAN Settings button.
4. Verify that the “Use proxy server” option is NOT checked. If it is checked, click in the
checked box to deselect the option and click 
OK.
To use the web-based management software, launch a suitable web browser and
direct it to the IP address of the Router. Type in http://
 followed by the default IP
address, 192.168.0.1 
in the address 
bar of the browser. The URL in the address
bar should read: http://192.168.0.1
.
In the page that opens, click on the Login to web-based management module
button:
A new window will appear and you will be prompted for a user name and
password to access the web-based manager. Use the default user name admin
and password admin
 for first time set up. You should change the web-based
manager access user name and password once you have verified that a
connection can be established. The user name and password allows any PC
within the same subnet as the Router to access the web-based manger.

NOTE: Do not confuse the user name and password used to access the web-based
manager with the ADSL account user name and password needed for PPP connections
to access the ADSL or network service provider’s network.
Logging in will bring up the main page of the web-based management module.
Click the DSL-500 folder in the main window. This folder will open revealing the
management menu options. These menus are used to configure the Router for
connection to the WAN and other router functions. This chapter discusses the
steps to first establish the WAN connection. The remaining features not directly
concerned with establishing the initial connection are explained in Chapter 5,
Web-based Management
.
Web-based Manager Main Menu
Configure the WAN Connection
Now that you have accessed the web-based manager, you must configure the
Router for the ADSL connection (VPI/VCI pair) and provide other information to
establish the WAN connection. The other information provided depends on the
type of WAN connection you have. For PPPoE and PPPoA connections, you will
need to provide a User Name and Password used for authentication purposes.
For “Bridged Ethernet” (RFC 1483) connections a static IP address must be used.
It is necessary to supply IP settings for the WAN connection and other
information discussed in Chapter 2, Prepare for Installation
. All connection
methods available to the Router are discussed in this chapter, beginning with
PPPoE connections. PPPoE is the most commonly used protocol to provide ADSL
connection and is the default method used by the Router. For a more detailed
discussion of the various menu items in the connection configuration windows,
see Chapter 5, Web-based Management
.
If you are using either a PPPoA or Bridged Ethernet (RFC 1483) connection it
will be necessary to change the connection method. Please read the section
Changing the Connection Type following the PPPoE Configuration section for
more information.
