This attribute indicates the total number of PLCP Far-End Block
Errors (FEBE) reported by the far-end terminal.
Counting of FEBEs is inhibited for second intervals where PLCP
Far-End Unavailable Seconds (FEUAS) are counted.
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.
