DSL-502G ADSL Ethernet Router User's Guide
Requirements for Installation
You will need a computer to set up and use the Router. In addition, it will be necessary to configure the device
using information provided by your ADSL service provider. This information is used to establish the parameters
of the ADSL connection and identify the Router on the WAN.
Configuration Computer Requirements
The Router can be configured using a computer that meets the conditions discussed here.
Operating System
The DSL-502G uses an HTML-based web interface for managing and monitoring the system. This web manager
may be accessed using any operating system capable of running web browser software. The firmware upgrade
utility however must be installed and used on a computer running a Microsoft Windows operating system.
Web Browser
Any common web browser such as Microsoft Internet Explorer or Netscape Navigator can be used to configure
the Router using the embedded web-based management software.
Ethernet Adapter (NIC)
All PCs using the Router for Internet access, including the Manager PC, must have an Ethernet NIC (Network
Interface Card) installed. Each computer on the internal network must have TCP/IP Protocol enabled. If you
have an existing Ethernet set up, the PCs should already meet this requirement.
If you are using the Router in the role of a simple bridge (RFC 1483), additional software may be needed for the
computer or server connected to the Router (on the LAN side). You may be instructed by your service provider
to configure the NIC card for DHCP or PPP connection. Your network service provider will give you more
information.
Connection Method
It is necessary to know the connection method used for the ADSL connection. The connection method is also
known as the ADSL Protocol, Encapsulation Protocol or Encapsulation Method. These protocols are defined by
"RFCs" which are internationally recognized standards for networking protocols. You will be required to
configure the Router to use the correct method. PPP connections require account information to be entered and
stored in the device. Bridged Ethernet connections require that the IP settings be set manually.
The Router supports three connection methods:
♦ PPP over ATM (RFC 2364) used by default
♦ PPP over Ethernet (RFC2516)
♦ IP over ATM (RFC 1577)
♦ Ethernet over ATM (RFC 1483)
