ADSL Modulation Settings
The default modulation technique used by the Router will automatically detect what ADSL protocol is used for
your account. However it can be changed to any of the recognized standard modulations used for ADSL. Select
the Modulation Type from the pull-down menu and click the Apply button to change the modulation.

PPP Settings
When the WAN connection is configured for either PPPoA or PPPoE, you can configure the Router’s PPP
session to remain on all the time, or to disconnect after some period of no activity. You may also choose to
instruct the Router to connect each time you want to access the WAN or the Internet.
Figure 4- 9. PPP Connection settings menu
If you want the Internet or WAN connection to be available any time a host on your LAN requests access, select
the Connect On Demand option and choose an idle time of 0 minutes..
If your ISP account is billed according to the amount of time the Router is connected, choose the Connection
On Demand option and configure the idle time to 1 or more minutes. The idle time tell the Router to disconnect
the PPP connection after a period of inactivity. This will discontinue the PPP session and require a few seconds
to reconnect when a host requests access to the WAN. Alternatively you can choose the Manual option and use
the Connect button to initiate a PPP connection each time you want to use the Router to access the WAN. If you
use the Manual option, you must return to this menu and click the Disconnect button to terminate the PPP
session.
