Abstract
In large multi-tiered hierarchical alarm systems for high capacity telecommunications transmission systems, it is important to notify the maintenance craft of only the highest alarm, and to notify only when the alarm has been validated by persisting for a sufficiently long time. Advantageously, this is accomplished by timing alarms and freezing the timing when a higher level alarm is detected. If the higher level alarm is no longer present, timing on the lower level frozen alarm signal continues until there is a timeout. A timed out alarm is reported to the maintenance craft.
