Bit by bit
incorrect HEC
Triggered by state transition (Case A) due to alpha consecutive incorrect HEC´s in the cell
delineation process (Fig. 5 of ITU-T Recommendation I.432.1)
Triggered by state transition (Case B) due to delta consecutive correct HEC´s in thecell delineation
process (Fig. 5 of ITU-T Recommendation I.432.1)
Triggered by 50 continuous ms in the OCD anomaly maintenance state
