+// EponDownstreamPerformanceMonitoringConfiguration (Class ID: #406 / 0x0196)
+//	This ME represents window sizes and threshold values for EPON downstream PM operations which are
+//	defined in [IEEE 802.3] as: errored symbol period, errored frame, errored frame period and
+//	errored frame seconds summary.
+//
+//	The EPON ONU automatically instantiates an instance of this ME for each ANI-E.
+//
+//	Relationships
+//		An instance of this ME is associated with an ANI-E.
+//
+//	Attributes
+//		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-E. (R, set-by-create) (mandatory) (2-bytes)
+//
+//		Errored Symbol Period Window
+//			This attribute specifies the number of symbols in the measurement period, as defined in clause
+//			57.5.3.1 of [IEEE 802.3]. (R, W) (optional) (8-bytes)
+//
+//		Errored Symbol Period Threshold
+//			This attribute specifies the threshold of errored symbols for generating an event report, as
+//			defined in clause 57.5.3.1 of [IEEE 802.3]. (R, W) (optional) (8-bytes)
+//
+//		Errored Frame Window
+//			This attribute specifies the duration in units of 100-ms of the measurement period, as defined
+//			in clause 57.5.3.2 of [IEEE 802.3]. (R, W) (optional) (2-bytes)
+//
+//		Errored Frame Threshold
+//			This attribute specifies the threshold of errored frames for generating an event report, as
+//			defined in clause 57.5.3.2 of [IEEE 802.3]. (R, W) (optional) (4-bytes)
+//
+//		Errored Frame Period Window
+//			This attribute specifies the duration in terms of frames of the measurement period, as defined
+//			in clause 57.5.3.3 of [IEEE 802.3]. (R, W) (optional) (4-bytes)
+//
+//		Errored Frame Period Threshold
+//			This attribute specifies the threshold of errored frames for generating an event report, as
+//			defined in clause 57.5.3.3 of [IEEE 802.3]. (R, W) (optional) (4-bytes)
+//
+//		Errored Frame Seconds Summary Window
+//			This attribute specifies the duration in units of 100ms of the measurement period, as defined in
+//			clause-57.5.3.4 of [IEEE-802.3]. (R, W) (optional) (2-bytes)
+//
+//		Errored Frame Seconds Summary Threshold
+//			This attribute specifies the threshold of errored frame seconds for generating an event report,
