+
+// Onu2G (class ID #257)
+//	This ME contains additional attributes associated with a PON ONU. The ONU automatically creates
+//	an instance of this ME. Its attributes are populated according to data within the ONU itself.
+//
+//	This ME is the same as the ONT2-G of [ITUT G.984.4], with extensions.
+//
+//	Relationships
+//		This ME is paired with the ONU-G entity.
+//
+//	Attributes
+//		Managed Entity Id
+//			Managed entity ID: This attribute uniquely identifies each instance of this ME. There is only
+//			one instance, number 0. (R) (mandatory) (2-bytes)
+//
+//		Equipment Id
+//			Equipment ID: This attribute may be used to identify the specific type of ONU. In some
+//			environments, this attribute may include the common language equipment identification (CLEI)
+//			code. (R) (optional) (20-bytes)
+//
+//		Optical Network Unit Management And Control Channel Omcc Version
+//			(R) (mandatory) (1-byte)
+//
+//		Vendor Product Code
+//			Vendor product code: This attribute contains a vendor-specific product code for the ONU. (R)
+//			(optional) (2-bytes)
+//
+//		Security Capability
+//			(R) (mandatory) (1-byte)
+//
+//		Security Mode
+//			Upon ME instantiation, the ONU sets this attribute to 1, AES-128. Attribute value 1 does not
+//			imply that any channels are encrypted; that process is negotiated at the PLOAM layer. It only
+//			signifies that the advanced encryption standard (AES) with 128-bit keys is the security mode to
+//			be used on any channels that the OLT may choose to encrypt. (R,-W) (mandatory) (1-byte)
+//
+//		Total Priority Queue Number
+//			Total priority queue number: This attribute reports the total number of upstream priority queues
+//			that are not associated with a circuit pack, but with the ONU in its entirety. Upon ME
+//			instantiation, the ONU sets this attribute to the value that represents its capabilities. (R)
+//			(mandatory) (2-bytes)
+//
+//		Total Traffic Scheduler Number
+//			Total traffic scheduler number: This attribute reports the total number of traffic schedulers
+//			that are not associated with a circuit pack, but with the ONU in its entirety. The ONU supports
+//			null function, strict priority scheduling and weighted round robin (WRR) from the priority
+//			control and guarantee of minimum rate control points of view, respectively. If the ONU has no
+//			global traffic schedulers, this attribute is 0. (R) (mandatory) (1-byte)
+//
+//		Deprecated
+//			Deprecated:	This attribute should always be set to 1 by the ONU and ignored by the OLT. (R)
+//			(mandatory) (1-byte)
+//
+//		Total Gem Port_Id Number
+//			Total GEM port-ID number: This attribute reports the total number of GEM port-IDs supported by
+//			the ONU. The maximum value is specified in the corresponding TC recommendations. Upon ME
+//			instantiation, the ONU sets this attribute to the value that represents its capabilities. (R)
+//			(optional) (2-bytes)
+//
+//		Sysuptime
+//			SysUpTime:	This attribute counts 10 ms intervals since the ONU was last initialized. It rolls
+//			over to 0 when full (see [IETF RFC 1213]). (R) (optional) (4-bytes)
+//
+//		Connectivity Capability
+//			(R) (optional) (2 bytes)
+//
+//		Current Connectivity Mode
+//			(R, W) (optional) (1 byte)
+//
+//		Quality Of Service Qos Configuration Flexibility
+//			The ME ID of both the T-CONT and traffic scheduler contains a slot number. Even when attributes
+//			in the above list are RW, it is never permitted to change the slot number in a reference. That
+//			is, configuration flexibility never extends across slots. It is also not permitted to change the
+//			directionality of an upstream queue to downstream or vice versa.
+//
+//		Priority Queue Scale Factor
+//			NOTE 3 - Some legacy implementations may take the queue scale factor from the GEM block length
+//			attribute of the ANI-G ME. That option is discouraged in new implementations.
+//
