Errored Seconds	(ES) For ESF links, the number of one-second intervals
	containing one or more Path Code Violations OR one or more
	Severely Errored Frame defects OR one or more Controlled Slip
	events OR a detected AIS defect.
	For D4 links, the presence of Bipolar Violations also triggers an
	Errored Second.
	ES is not incremented during an Unavailable Second.
Severely Errored	(SES) For ESF links, the number of one-second intervals
Seconds	containing 320 or more Path Code Violation Error Events OR
	one or more Out of Frame defects OR a detected AIS defect.
	For D4 signals, The number of one-second intervals with
	Framing Error events, or an OOF defect, or 1544 LCVs or more.
	Controlled slips are not included in this parameter.
	SES is not incremented during an Unavailable Second.
Severely Errored	(SEFS) The number of one-second intervals containing one
Frame Seconds	or more Out of Frame defects OR a detected AIS defect.
Line Errored Seconds	(LES) The number of one-second intervals containing one or
	more line errors.
Controlled Slip Seconds	(CSS) The number of one-second intervals containing one or
	more controlled slips.
Bursty Errored Seconds	(BES) Also known as Errored Second type B. The number of
	one-second intervals with fewer than 320 and more than 1 Path
	Coding Violation error event, no Severely Errored Frame
	defects, and no detected incoming AIS defects. Controlled slips
	are not included in this parameter.
	BES is not incremented during an Unavailable Second.
Degraded Minutes	(DM) The total number of minutes in which the estimated error
	rate exceeds 1E-6 but does not exceed 1E-3. Degraded Minutes
	are determined by collecting all of the Available Seconds,
	removing any Severely Errored Seconds, grouping the result in
	60-second long groups, and counting a 60-second long group
	(one minute) as degraded if the cumulative errors during the
	seconds present in the group exceed 1E-6. Available seconds are
	merely those seconds that are not Unavailable (UAS).
Line Code Violations	(LCV or CV) The total number of line code violations that have
	been detected during the measurement interval. An LCV is the
	occurrence of a Bi-polar Violation (BPV) or Excessive Zeros.
