This attribute indicates the total number of Line Code Violations
(LCV) detected. A DS3 Line Code Violation is a B3Zs error. LCV
counting is inhibited for second intervals where Line Severely
Errored Second (LSES) is 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.
