This object carries a standardized event type code, drawn from the ITU-T M.3100, X.733, and X.736 recommendations, describing the category of alarm condition being reported, such as equipment failure or communications alarm. An operator uses this standardized code to classify incoming alarms consistently across multi-vendor equipment that all implement this common alarm model. For example, eventTypePem reporting a value corresponding to 'communicationsAlarm' tells the operator this event relates to a link or protocol failure rather than a hardware malfunction.
