+
+// EnhancedTcPerformanceMonitoringHistoryData (class ID #454)
+//	This ME collects PM data associated with the XGS-PON and subsequent ITU-T PON systems' TC layer.
+//
+//	For a complete discussion of generic PM architecture, refer to clause I.4.
+//
+//	Relationships
+//		An instance of this ME is associated with an ANI-G.
+//
+//	Attributes
+//		Managed Entity Id
+//			Managed entity ID: This attribute uniquely identifies each instance of this ME. Through an
+//			identical ID, this ME is implicitly linked to an instance of the ANI-G. (R, set-by-create)
+//			(mandatory) (2-bytes)
+//
+//		Interval End Time
+//			Interval end time: This attribute identifies the most recently finished 15-min interval. (R)
+//			(mandatory) (1-byte)
+//
+//		Threshold Data 64 Bit Id
+//			Threshold data 64-bit ID: This attribute points to an instance of the threshold data 64-bit ME
+//			that contains PM threshold values. (R,-W, setbycreate) (mandatory) (2-bytes)
+//
+//		Psbd Hec Error Count
+//			PSBd HEC error count: This attribute counts HEC errors in any of the fields of the downstream
+//			physical sync block. (R) (optional) (4-bytes)
+//
+//		Xgtc Hec Error Count
+//			XGTC HEC error count: This attribute counts HEC errors detected in the XGTC header. In [ITU-T
+//			G.9807.1], this attribute is used for FS HEC error count management. (R) (optional) (4-bytes)
+//
+//		Unknown Profile Count
+//			Unknown profile count: This attribute counts the number of grants received whose specified
+//			profile was not known to the ONU. (R) (optional) (4-bytes)
+//
+//		Transmitted Xgem Frames
+//			Transmitted XGEM frames: This attribute counts the number of non-idle XGEM frames transmitted.
+//			If an SDU is fragmented, each fragment is an XGEM frame and is counted as such. (R) (mandatory)
+//			(8 bytes)
+//
+//		Fragment Xgem Frames
+//			Fragment XGEM frames: This attribute counts the number of XGEM frames that represent fragmented
+//			SDUs, as indicated by the LF bit = 0. (R) (optional) (8-bytes)
+//
+//		Xgem Hec Lost Words Count
+//			XGEM HEC lost words count: This attribute counts the number of 4-byte words lost because of an
+//			XGEM frame HEC error. In general, all XGTC payload following the error is lost, until the next
+//			PSBd event. (R) (optional) (8 bytes)
+//
+//		Xgem Key Errors
+//			(R) (mandatory) (8 bytes)
+//
+//		Xgem Hec Error Count
+//			XGEM HEC error count: This attribute counts the number of instances of an XGEM frame HEC error.
+//			(R) (mandatory) (8 bytes)
+//
+//		Transmitted Bytes In Non_Idle Xgem Frames
+//			Transmitted bytes in non-idle XGEM frames: This attribute counts the number of transmitted bytes
+//			in non-idle XGEM frames. (R) (mandatory) (8 bytes)
+//
+//		Received Bytes In Non_Idle Xgem Frames
+//			Received bytes in non-idle XGEM frames: This attribute counts the number of received bytes in
+//			non-idle XGEM frames. (R) (optional) (8 bytes)
+//
+//		Lods Event Count
+//			LODS event count: This attribute counts the number of state transitions from O5.1 to O6. (R)
+//			(optional) (4-bytes)
+//
+//		Lods Event Restored Count
+//			LODS event restored count: This attribute counts the number of LODS cleared events. (R)
+//			(optional) (4-bytes)
+//
+//		Onu Reactivation By Lods Events
+//			ONU reactivation by LODS events: This attribute counts the number of LODS events resulting in
+//			ONU reactivation without synchronization being reacquired. (R) (optional) (4-bytes)
+//
