The modem temperature abate threshold value. If modem
temperature goes below the threshold and the value of
c3gModemTemperAbateNotifEnabled is 'true', the
c3gModemTemperAbateNotif notification will be sent. The value
of c3gModemTemperAbateNotifThreshold should be less than or
equal to the value of c3gModemTemperOnsetNotifThreshold.
e.g. setting c3gModemTemperAbateNotifThreshold to 50 degree
Celsius and then setting c3gModemTemperOnsetNotifThreshold
to 40 degree Celsius is not allowed and will be rejected.
