#### Details

A degraded minute is one in which the estimated error rate exceeds 1E-6 but does not exceed 1E-3 (see CCITT Specifications Volume III, Recommendation G.821).

Degraded minutes are determined by the following process:

1. Collecting all of the available seconds.

2. Removing any severely errored seconds.

3. Grouping the result in 60-second long groups.

4. Counting a 60-second long group as degraded if the cumulative errors during the seconds present in the group exceed 1E-6.

Available seconds are those seconds that are not unavailable seconds (dsx1CurrentUASs).
