This read-only CwrCwDegradedMinute value reports the number of Codeword Degraded Minutes detected since link power-up, as captured at the timestamp recorded in cwr24HrUpdateTime. It gives an admin the degraded-minutes figure for that specific 24-hour reporting entry, tracking minute-level quality dips on a daily basis. For example, an admin might notice a particular day's cwr24HrDegradedMinutes entry is unusually high even though no severely errored seconds were recorded that same day, indicating a day of mild but frequent degradation rather than outright errors.
