+
+// TwdmChannelPhyLodsPerformanceMonitoringHistoryData (class ID #444)
+//	This ME collects certain PM data associated with the slot/circuit pack, hosting one or more
+//	ANI-G MEs, and 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 1_2 Id
+//			Threshold data 1/2 ID: This attribute points to an instance of the threshold data 1 and 2 MEs
+//			that contains PM threshold values. (R, W, setbycreate) (mandatory) (2 bytes)
+//
+//		Total Received Words Protected By Bit_Interleaved Parity _32 Bip_32
+//			Total received words protected by bit-interleaved parity-32 (BIP-32): The count of 4 byte words
+//			included in BIP-32 check. This is a product of the number of downstream FS frames received by
+//			the size of the downstream FS frame after the FEC parity byte, if any, have been removed. The
+//			count applies to the entire downstream data flow, whether or not addressed to that ONT. (R)
+//			(mandatory) (8 bytes)
+//
+//		Bip_32 Bit Error Count
+//			BIP-32 bit error count: Count of the bit errors in the received downstream FS frames as measured
+//			using BIP-32. If FEC is supported in the downstream direction, the BIP-32 count applies to the
+//			downstream FS frame after the FEC correction has been applied and the FEC parity bytes have been
+//			removed. (R) (mandatory) (4 bytes)
+//
+//		Corrected Psbd Hec Error Count
+//			Corrected PSBd HEC error count: The count of the errors in either CFC or OCS fields of the PSBd
+//			block that have been corrected using the HEC technique. (R) (mandatory) (4 bytes)
+//
+//		Uncorrectable Psbd Hec Error Count
+//			Uncorrectable PSBd HEC error count: The count of the errors in either CFC or OCS fields of the
+//			PSBd block that could not be corrected using the HEC technique. (R) (mandatory) (4 bytes)
+//
+//		Corrected Downstream Fs Header Hec Error Count
+//			Corrected downstream FS header HEC error count: The count of the errors in the downstream FS
+//			header that have been corrected using the HEC technique. (R) (mandatory) (4 bytes)
+//
+//		Uncorrectable Downstream Fs Header Hec Error Count
+//			Uncorrectable downstream FS header HEC error count: The count of the errors in the downstream FS
+//			header that could not be corrected using the HEC technique. (R) (mandatory) (4 bytes)
+//
+//		Total Number Of Lods Events
+//			Total number of LODS events: The count of the state transitions from O5.1/O5.2 to O6, referring
+//			to the ONU activation cycle state machine, clause 12 of [ITU-T G.989.3]. (R) (mandatory)
+//			(4 bytes)
+//
+//		Lods Events Restored In Operating Twdm Channel
+//			LODS events restored in operating TWDM channel: The count of LODS events cleared automatically
+//			without retuning. (R) (mandatory) (4 bytes)
+//
+//		Lods Events Restored In Protection Twdm Channel
+//			LODS events restored in protection TWDM channel: The count of LODS events resolved by retuning
+//			to a pre-configured protection TWDM channel. The event is counted against the original operating
+//			channel. (R) (mandatory) (4 bytes)
+//
+//		Lods Events Restored In Discretionary Twdm Channel
+//			LODS events restored in discretionary TWDM channel: The count of LODS events resolved by
+//			retuning to a TWDM channel chosen by the ONU, without retuning. Implies that the wavelength
+//			channel protection for the operating channel is not active. The event is counted against the
+//			original operating channel (R) (mandatory) (4 bytes)
+//
+//		Lods Events Resulting In Reactivation
+//			LODS events resulting in reactivation: The count of LODS events resolved through ONU
+//			reactivation; that is, either TO2 (without WLCP) or TO3 + TO4 (with WLCP) expires before the
+//			downstream channel is reacquired, referring to the ONU activation cycle state machine, clause 12
+//			of [ITU-T G.989.3]. The event is counted against the original operating channel (R) (mandatory)
+//			(4 bytes)
+//
+//		Lods Events Resulting In Reactivation After Retuning To Protection Twdm Channel
+//			LODS events resulting in reactivation after retuning to protection TWDM channel: The count of
+//			LODS events resolved through ONU reactivation after attempted protection switching, which turns
+//			unsuccessful due to a handshake failure. (R) (mandatory) (4 bytes)
+//
+//		Lods Events Resulting In Reactivation After Retuning To Discretionary Twdm Channel
+//			LODS events resulting in reactivation after retuning to discretionary TWDM channel: The count of
+//			LODS events resolved through ONU reactivation after attempted retuning to a discretionary
+//			channel, which turns unsuccessful due to a handshake failure. (R) (mandatory) (4 bytes)
