(Errored Second) - For ESF mode, an errored second is defined as a second with one or more Path
ES
Code Violations (PCVs), or one or more Out of Frame (OOF) defects, or one or more Controlled Slip
events, or a detected AIS (blue alarm) defect. For D4 (SF) mode, the presence of Bipolar Violations
(BPVs) also triggers an errored second.
