+
+// OctetString (class ID #307)
+//	The octet string is modelled on the large string ME. The large string is constrained to
+//	printable characters because it uses null as a trailing delimiter. The octet string has a length
+//	attribute and is therefore suitable for arbitrary sequences of bytes.
+//
+//	Instances of this ME are created and deleted by the OLT. To use this ME, the OLT instantiates
+//	the octet string ME and then points to the created ME from other ME instances. Systems that
+//	maintain the octet string should ensure that the octet string ME is not deleted while it is
+//	still linked.
+//
+//	Relationships
+//		An instance of this ME may be cited by any ME that requires an octet string that can exceed
+//		25-bytes in length.
+//
+//	Attributes
+//		Managed Entity Id
+//			Managed entity ID: This attribute uniquely identifies each instance of this ME. The values 0 and
+//			0xFFFF are reserved. (R, setbycreate) (mandatory) (2-bytes)
+//
+//		Length
+//			Length:	This attribute specifies the number of octets that comprise the sequence of octets. This
+//			attribute defaults to 0 to indicate no octet string is defined. The maximum value of this
+//			attribute is 375 (15 parts, 25-bytes each). (R,-W) (mandatory) (2-bytes)
+//
+//		Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, Part 7, Part 8, Part 9, Part 10, Part 11, Part 12, Part 13, Part 14, Part 15
+//			Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, Part 7, Part 8, Part 9,  Part 10, Part 11, Part
+//			12, Part 13, Part 14, Part 15:  (R,-W) (part 1 mandatory, others optional) (25-bytes * 15
+//			attributes)
