Parameter	Definition
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.
