startup and be ready for the client device to dial up to the cellular network using
PPPoE.

 Bridged with Serial: When this type selected, the MB6800 acts as a modem
between the cellular network and the serial port. You can attach a DTE device
such as Cisco router or PC with the serial cable, and then initiate a PPP
procedure on the client device.

 Keepalive: This can detect whether the WWAN connection is in good status. When
the WWAN connection is abnormal, keep-alive module will detect it if keep-alive is
enabled and the router will try to reconnect automatically. When the system is still
abnormal, modem will be restarted. After modem is consecutively restarted for
several (configurable) times and the system still could not turn well, the router will
be rebooted automatically. Check the box to enable the Keep-Alive feature. If the
Keep-Alive is enabled, MB6800 will detect the Internet connection health periodically
with the interval specified. Once it detects the Internet connection goes down, it will
try to connect again. It will try to re-connect several times (3 times by default). If all of
the attempts fail, MB6800 will reset the 3G data card modem. If still no help, MB6800
will reboot itself after several attempts (3 times by default) fail.
