5.6.3 Cellular Modem Watchdog
When you select Enable Dial-Out on the System: Dial menu, you will be given the option to configure a cellular modem
watchdog service (with firmware version 3.5.2u13 and later). This service will periodically ping a configurable IP address. If a
set threshold number of consecutive attempts fail, the service will cause the unit to reboot. This can be used to force a clean
restart of the modem and its services to work around any carrier issues.
