Usage guidelines
This function enables the 3G/4G modem to reset automatically if the number of consecutive dialup
failures reaches the threshold set with the modem response command.
With this function disabled, the system automatically resets the modem only if the following conditions
are met:
• The 3G/4G modem has a successful dialup record after the last modem reset.
• The number of consecutive dialup failure reaches the threshold set with the modem response
command.
This function avoids the failures to restore links caused by an abnormal 3G/4G network.
When you enable this function, make sure other configurations are correct. Incorrect configurations
might cause undesirable modem reset.
