This counts pseudowire (PWE) packets that were expected at the receiving end but never arrived at all. A rising Miss count on this pseudowire means packets are being lost somewhere in the underlying packet network (congestion, a flapping link, a reconvergence event), and because CESoP has no retransmission, each missing packet becomes an actual gap in the reconstructed TDM bitstream rather than just a delay -- 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 80 -- a concrete count the admin can trend against neighboring bins to judge whether the condition it reflects is worsening.
