A shortterm alarm is declared when the detected defects persist for tens of milliseconds. A carrier failure alarm (CFA) is a duration of carrier system outage. CFA types reported can be mapped to CFAs defined in TIA-547A and TR62411 as follows: The criteria for declaring and clearing the alarms is selectable to meet those in TIA-547A or TR64211.
