This read-only counter reports the number of far-end coding violations detected on this SONET path during the current 24-hour interval, as signaled back from the remote end. It gives an admin visibility into signal-quality problems on the remote side of the circuit that wouldn't show up in local-end counters. For instance, a steadily rising far-end CV count with a stable near-end count suggests the remote transmitter or its outbound fiber run needs inspection.
