+
+// AniG (class ID #263)
+//	This ME organizes data associated with each access network interface supported by a GPON ONU.
+//	The ONU automatically creates one instance of this ME for each PON physical port.
+//
+//	Relationships
+//		An instance of this ME is associated with each instance of a physical PON interface.
+//
+//	Attributes
+//		Managed Entity Id
+//			Managed entity ID: This attribute uniquely identifies each instance of this ME. Its value
+//			indicates the physical position of the PON interface. The first byte is the slot ID, defined in
+//			clause 9.1.5. The second byte is the port ID. (R) (mandatory) (2-bytes)
+//
+//		Sr Indication
+//			SR indication: This Boolean attribute indicates the ONU's capability to report queue status for
+//			DBA. The value true means that status reporting is available for all TCONTs that are associated
+//			with the ANI. (R) (mandatory) (1-byte)
+//
+//		Total TCont Number
+//			Total TCONT number: This attribute indicates the total number of T-CONTs that can be supported
+//			on this ANI. (R) (mandatory) (2-bytes)
+//
+//		Gem Block Length
+//			In all other ITU-T PON systems, the unit for queue occupancy reporting is fixed in at 4-bytes by
+//			the respective TC layer specification.
+//
+//		Piggyback Dba Reporting
+//			(R) (mandatory) (1-byte)
+//
+//		Deprecated
+//			Deprecated:	This attribute should be set to 0 by the ONU and ignored by the OLT. (R) (mandatory)
+//			(1-byte)
+//
+//		Signal Fail Threshold
+//			Signal fail (SF) threshold: This attribute specifies the downstream bit error rate (BER)
+//			threshold to detect the SF alarm. When this value is y, the BER threshold is 10-y. Valid values
+//			are 3..8. Upon ME instantiation, the ONU sets this attribute to 5. (R,-W) (mandatory) (1-byte)
+//
+//		Signal Degrade Threshold
+//			Signal degrade (SD) threshold: This attribute specifies the downstream BER threshold to detect
+//			the SD alarm. When this value is x, the BER threshold for SD is 10-x. Valid values are 4..10.
+//			The SD threshold must be lower than the SF threshold; i.e., x-> y. Upon ME instantiation, the
+//			ONU sets this attribute to 9. (R,-W) (mandatory) (1-byte)
+//
+//		Arc
+//			ARC:	See clause A.1.4.3. (R,-W) (optional) (1-byte)
+//
+//		Arc Interval
+//			ARC interval: See clause A.1.4.3. (R,-W) (optional) (1-byte)
+//
+//		Optical Signal Level
+//			Optical signal level: This attribute reports the current measurement of the total downstream
+//			optical signal level. Its value is a 2s complement integer referred to 1- mW (i.e., 1-dBm), with
+//			0.002 dB granularity. (R) (optional) (2-bytes)
+//
+//		Lower Optical Threshold
+//			Lower optical threshold: This attribute specifies the optical level the ONU uses to declare the
+//			downstream low received optical power alarm. Valid values are  -127 dBm (coded as 254) to 0 dBm
+//			(coded as 0) in 0.5 dB increments. The default value 0xFF selects the ONU's internal policy.
+//			(R,-W) (optional) (1-byte)
+//
+//		Upper Optical Threshold
+//			Upper optical threshold: This attribute specifies the optical level the ONU uses to declare the
+//			downstream high received optical power alarm. Valid values are  -127 dBm (coded as 254) to 0 dBm
+//			(coded as 0) in 0.5 dB increments. The default value 0xFF selects the ONU's internal policy.
+//			(R,-W) (optional) (1-byte)
+//
+//		Onu Response Time
+//			(R) (optional) (2-bytes)
+//
+//		Transmit Optical Level
+//			Transmit optical level: This attribute reports the current measurement of mean optical launch
+//			power. Its value is a 2s complement integer referred to 1-mW (i.e., 1-dBm), with 0.002 dB
+//			granularity. (R) (optional) (2-bytes)
+//
+//		Lower Transmit Power Threshold
+//			Lower transmit power threshold: This attribute specifies the minimum mean optical launch power
+//			that the ONU uses to declare the low transmit optical power alarm. Its value is a 2s complement
+//			integer referred to 1-mW (i.e., dBm), with 0.5-dB granularity. The default value -63.5 (0x81)
+//			selects the ONU's internal policy. (R,-W) (optional) (1-byte)
+//
+//		Upper Transmit Power Threshold
+//			Upper transmit power threshold: This attribute specifies the maximum mean optical launch power
+//			that the ONU uses to declare the high transmit optical power alarm. Its value is a 2s complement
+//			integer referred to 1-mW (i.e., dBm), with 0.5-dB granularity. The default value -63.5 (0x81)
+//			selects the ONU's internal policy. (R,-W) (optional) (1-byte)
