 //	Attributes
 //		Managed Entity Id
-//			Managed entity ID:	This attribute uniquely identifies each instance of this ME. This 2 byte
-//			number indicates the physical position of the UNI. The six LSBs of the first byte are the slot
-//			ID, defined in clause 9.1.5. The two MSBs indicate the channel number in some of the implicitly
-//			linked MEs, and must be 0 in the PPTP itself. This reduces the possible number of physical slots
-//			to 64. The second byte is the port ID, with the range 1..255. (R) (mandatory) (2-bytes)
