PPP/MP Setup
Link Type – There are three link types provided here for
different purpose. Link Disable disables the ISDN dial-out
function. Dialup 64Kbps allows you to use one ISDN B
channel for Internet access. Dialup 128Kbps allows you to use
both ISDN B channels for Internet access. Dialup BOD (for
detailed information of configuration, please refer to section
3.12.4) stands for bandwidth-on-demand. The router will use
only one B channel in low traffic situations. Once the single B
channel bandwidth is fully used, the other B channel will be
activated automatically through the dialup. For more detailed
BOD parameter settings, please refer to the section of Call
Control.
PPP Authentication - PAP only allows you to configure the
PPP session to use the PAP protocol to negotiate the username
and password with the ISP. PAP or CHAP is to configure the
PPP session to use the PAP or CHAP protocols to negotiate the
username and password with the ISP.
Idle Timeout - Idle timeout means the router will be disconnect
after being idle for a preset amount of time. The default is 180
seconds. If you set the time to 0, the ISDN connection to the
ISP will always remain on.
