EFS
Error Free Seconds (EFS) is calculated whenever ESR is calculated, and is the simple
percentage complement of ESR: EFS = 100.0 - ESR. When there have been UAS in
the statistics history for the past 24 hours, then EFS is set at 100%.
ESR
Errored Second Ratio (ESR) is the ratio of ES to total seconds in available time during
a fixed measurement interval. The fixed interval is the last 24 hours before the current
15-minute interval. When there have been UAS in the statistics history for the past 24
hours, then ESR is set at 0%.
SESR
Severely Errored Second Ration (SESR) is the ratio of SES to total seconds in
available time during a fixed-measurement interval. The fixed interval to be used is
the last 24 hours before the current 15-minute interval. When there have been UAS
in the statistics history for the past 24 hours, then SESR is set at 0%.
BBER
Background Block Error Ratio (BBER) is the ratio of errored blocks to total blocks
during a fixed-measurement interval, excluding all blocks during SES and unavailable
time. The fixed interval is equal to the last 24 hours before the current 15-minute
interval.
