Broadband Router with 2 Phone Ports
Static IP
If you are required to use a permanent IP address, then select Static IP.
IP Address. This is the IP address that the Router has, when seen from the Internet. Your ISP will provide you
with the IP Address you need to specify here.
Subnet Mask. This is the Router's Subnet Mask, as seen by external users on the Internet (including your
ISP). Your ISP will provide you with the Subnet Mask.
Default Gateway. Your ISP will provide you with the Default Gateway Address.
DNS 1-3. Your ISP will provide you with at least one DNS (Domain Name System) Server IP Address.
PPPoE
Some DSL-based ISPs use PPPoE (Point-to-Point Protocol over Ethernet) to establish Internet connections for
end-users. If you use a DSL line, check with your ISP to see if they use PPPoE. If they do, you will have to
enable it.
User Name and Password. Enter the User Name and Password provided by your ISP.
Service Name. If provided by your ISP, enter the Service Name.
Connect on Demand and Max Idle Time. You can configure the Router to cut the Internet connection after it
has been inactive for a specific period of time (Max Idle Time). If your Internet connection has been
terminated due to inactivity, Connect on Demand enables the Router to automatically re-establish your
connection as soon as you attempt to access the Internet again. If you wish to activate Connect on Demand,
click the radio button. If you want your Internet connection to remain on at all times, enter 0 in the Max Idle
Time field. Otherwise, enter the number of minutes you want to have elapsed before your Internet access
disconnects.
Keep Alive and Redial Period. This option keeps your PPPoE-enabled Internet access connected indefinitely,
even when it sits idle. If you select this option, the Router will periodically check your Internet connection. If
the connection is down, then the Router will automatically re-establish the connection. To use this option,
click the radio button next to Keep Alive. The default Redial Period is 30 seconds.
When you are finished, click the Save Settings button. Then click the Status tab, and click the Connect
button to start the connection.
Note: For DSL users, if you need to enable PPPoE support, remember to remove any PPPoE
applications that are installed on your PCs.
