PPP General
PPP Enable/disable PPP. The default is Disable. When enabled, the unit functions as a router. PPP
must be disabled to access the integrated cellular modem directly using telnet port 5000. If
PPP is enabled, you cannot access the integrated cellular modem.
Dial-on-Demand: Enable/disable Dial-on-Demand. The default is Disable. If you disable it, the router will always
stay connected unless the Idle Time Out expires. When Dial-on-Demand is enabled, use the
‘Wakeup on Call’ settings under the PPP menu to configure the settings for re-establishment
of the connection.
Idle Time Out: Set the amount of idle time that will pass before the router will timeout. The default is 180

the connection from dropping.
