+//	Attributes

+//			Managed entity ID: This attribute uniquely identifies each instance of this ME. (R, setbycreate)
+//			(mandatory) (2-bytes)
+//
+//		Ces Buffered Cdv Tolerance
+//			CES buffered CDV tolerance: This attribute represents the duration of user data that must be
+//			buffered by the CES IW entity to offset packet delay variation. It is expressed in 10-us
+//			increments. 75 (750-vs) is suggested as a default value. (R,-W, setbycreate) (mandatory)
