This attribute indicates the total count of DS3 frames containing a
Coding Violation on the Far-End (FECV), also known as a Far-End
Block Error (FEBE). Each FEBE is reported over the FEBE bits
each time the far-end DS3 terminal detects a C-BIT Parity error
over a received DS3 frame. For second intervals where Far-End
Unavailable Seconds (FEAUS) or Far-End Severely Errored
Seconds (FESES) are counted, counting of FECVs is inhibited.
This attribute is a non-negative integer which monotonically
increases until it reaches a maximum value, at which point it wraps
around and starts increasing again from zero.
