+// GemInterworkingTerminationPoint (class ID #266)
+//	An instance of this ME represents a point in the ONU where the IW of a bearer service (usually
+//	Ethernet) to the GEM layer takes place. At this point, GEM packets are generated from the bearer
+//	bit stream (e.g., Ethernet) or the bearer bit stream is reconstructed from GEM packets.
+//
+//	Instances of this ME are created and deleted by the OLT.
+//
+//	Relationships
+//		One instance of this ME exists for each transformation of a data stream into GEM frames and vice
+//		versa.
+//
+//	Attributes
+//		Managed Entity Id
+//			Managed entity ID: This attribute uniquely identifies each instance of this ME. (R, setbycreate)
+//			(mandatory) (2-bytes)
+//
+//		Gem Port Network Ctp Connectivity Pointer
+//			GEM port network CTP connectivity pointer: This attribute points to an instance of the GEM port
+//			network CTP. (R,-W, setbycreate) (mandatory) (2-bytes)
+//
+//		Interworking Option
+//			(R,-W, setbycreate) (mandatory) (1-byte)
+//
+//		Service Profile Pointer
+//			NOTE - The video return path (VRP) service profile is defined in [ITU-T G.984.4].
+//
+//		Interworking Termination Point Pointer
+//			In all other GEM services, the relationship between the related service TP and this GEM IW TP is
+//			derived from other ME relations; this attribute is set to a null pointer and not used. (R,-W,
+//			setbycreate) (mandatory) (2-bytes)
+//
+//		Pptp Counter
+//			PPTP counter: This value reports the number of PPTP ME instances associated with this GEM IW TP.
+//			(R) (optional) (1-byte)
+//
+//		Operational State
+//			Operational state: This attribute indicates whether the ME is capable of performing its
+//			function. Valid values are enabled (0) and disabled (1). (R) (optional) (1-byte)
+//
+//		Gal Profile Pointer
+//			(R,-W, setbycreate) (mandatory) (2-bytes)
+//
+//		Gal Loopback Configuration
+//			The default value of this attribute is 0. When the IW option is 6 (downstream broadcast), this
+//			attribute is not used. (R,-W) (mandatory) (1-byte)
+//
