 //		Severely Errored Seconds
+//			This attribute counts severely errored seconds (SES-LFE). An SES is declared if, during a 1-s

+//			counting FEBE anomalies directly.

 //		Unavailable Seconds
+//			The far-end xDSL termination becomes unavailable at the onset of 10 contiguous SES-LFEs. The 10
+//			SES-LFEs are included in unavailable time. Once unavailable, the far-end line becomes available
+//			at the onset of 10 contiguous seconds with no SES-LFEs. The 10-s with no SES-LFEs are excluded
+//			from unavailable time. Some attribute counts are inhibited during unavailability - see clause
+//			7.2.7.13 of [ITUT G.997.1].

 //		Leftr Defect Seconds
 //			"leftr" defect seconds: If retransmission is used, this parameter is a count of the seconds with
 //			a near-end ''leftr'' defect present - see clause 7.2.1.1.6 of [ITUT-G.997.1]. (R) (optional)
