+// TwdmChannelXgemPerformanceMonitoringHistoryData (class ID #445)
+//	This ME collects certain XGEM-related PM data associated with the slot/circuit pack, hosting one
+//	or more ANI-G MEs, for a specific TWDM channel. Instances of this ME are created and deleted by
+//	the OLT.
+//
+//	For a complete discussion of generic PM architecture, refer to clause I.4.
+//
+//	Relationships
+//		An instance of this ME is associated with an instance of TWDM channel ME.
+//
+//	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 TWDM channel ME. (R,
+//			setbycreate) (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)
+//
+//		Total Transmitted Xgem Frames
+//			Total transmitted XGEM frames: The counter aggregated across all XGEM ports of the given ONU.
+//			(R) (mandatory) (8-byte)
+//
+//		Transmitted Xgem Frames With Lf Bit Not Set
+//			Transmitted XGEM frames with LF bit not set: The counter aggregated across all XGEM ports of the
+//			given ONU identifies the number of fragmentation operations. (R) (mandatory) (8-byte)
+//
+//		Total Received Xgem Frames
+//			Total received XGEM frames: The counter aggregated across all XGEM ports of the given ONU. (R)
+//			(mandatory) (8-byte)
+//
+//		Received Xgem Frames With Xgem Header Hec Errors
+//			Received XGEM frames with XGEM header HEC errors: The counter aggregated across all XGEM ports
+//			of the given ONU identifies the number of loss XGEM frame delineation events. (R) (mandatory)
+//			(8-byte)
+//
+//		Fs Words Lost To Xgem Header Hec Errors
+//			FS words lost to XGEM header HEC errors: The counter of the FS frame words lost due to XGEM
+//			frame header errors that cause loss of XGEM frame delineation. (R) (mandatory) (8-byte)
+//
+//		Xgem Encryption Key Errors
+//			XGEM encryption key errors: The counter aggregated across all XGEM ports of the given ONU
+//			identifies the number of received XGEM frames that have to be discarded because of unknown or
+//			invalid encryption key. The number is included into the Total received XGEM frame count above.
+//			(R) (mandatory) (8-byte)
+//
+//		Total Transmitted Bytes In Non_Idle Xgem Frames
+//			Total transmitted bytes in non-idle XGEM frames: The counter aggregated across all XGEM ports of
+//			the given. (R) (mandatory) (8-byte)
+//
+//		Total Received Bytes In Non_Idle Xgem Frames
+//			Total received bytes in non-idle XGEM frames: The counter aggregated across all XGEM ports of
+//			the given ONU. (R) (mandatory) (8-byte)
