This counts individual TDM path-layer code-violation events, rather than affected seconds, on the circuit carried over this pseudowire. CVP on this PW lets the admin see whether path errors are a dense burst of violations packed into few seconds or a low steady trickle, a distinction the seconds-based ESP counter on the same PW can't make on its own -- and this specific object covers a closed 24-hour history bin -- a final, day-over-day comparable count rather than a live figure. For example, over that completed 24-hour bin, this pseudowire might show this counter at 600 -- a concrete count the admin can trend against neighboring bins to judge whether the condition it reflects is worsening.
