A count of E3 frames containing a Far-End Block Error (FEBE). A
FEBE is reported over the FEBE bit each time the far-end terminal
detects a BIP-8 error in a received E3 frame. For second intervals
where Far End Unavailable Seconds (FEUAS) 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.
