DSL-514 ADSL Router User’s Guide

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-514 can be used in four 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) 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.
