This read-only value is the current-interval count of P-bit Coding Violations, individual parity-bit errors rather than whole errored seconds, on this DS3 interface, applicable only for DS3. It gives a finer-grained error count than csDs3StatCurrentPESs, letting an admin gauge error density rather than just how many seconds were affected. For example, an admin compares csDs3StatCurrentPCVs against csDs3StatCurrentPESs for the same interval to judge whether errors are concentrated in a few bad seconds or spread thinly across many.
