Object
notification
Alarm Indication Signal - a signal, associated with a maintenance alarm detected on a defective maintenance span, that is transmitted in the direction of the defect as a substitute for the normal signal. Its purpose is to show downstream entities that a defect has been identified, so that other maintenance alarms consequent to this first defect can be inhibited. The external bit stream representation of AIS may be an all 1s signal.
