This object gives a standardized probable-cause code for an alarm, drawn from the large enumeration defined across ITU M.3100, X.733, X.736, and ETSI GSM 12.11, offering a more generic classification than the vendor-specific alarmSpecificProblem. An admin uses it to correlate alarms across equipment from different vendors that all follow the same ITU cause codes, easing automated alarm correlation and reporting. For example, a value of m3100LossOfSignal(8) tells the operator the underlying issue is a physical-layer signal loss rather than, say, a software fault.
