+// PwAtmConfigurationData (class ID #337)
+//	This ME contains generic configuration data for an ATM pseudowire. Definitions of attributes are
+//	from PW-ATM-MIB [IETF RFC 5605]. Instances of this ME are created and deleted by the OLT.
+//
+//	Relationships
+//		An instance of this ME is associated with an instance of the MPLS pseudowire TP ME with a
+//		pseudowire type attribute equal to one of the following.////		2	ATM AAL5 SDU VCC transport////		3	ATM transparent cell transport////		9	ATM n-to-one VCC cell transport////		10	ATM n-to-one VPC cell transport////		12	ATM one-to-one VCC cell mode////		13	ATM one-to-one VPC cell mode////		14	ATM AAL5 PDU VCC transport////		Alternatively, an instance of this ME may be associated with an Ethernet flow TP or a TCP/UDP
+//		config data ME, depending on the transport layer of the pseudowire.
+//
+//	Attributes
+//		Managed Entity Id
+//			Managed entity ID: This attribute uniquely identifies each instance of this ME. (R,
+//			setbycreate)-(mandatory) (2 bytes)
+//
+//		Tp Type
+//			2	TCP/UDP config data
+//
+//		Transport Tp Pointer
+//			Transport TP pointer: This attribute points to an associated instance of the transport layer TP,
+//			whose type is specified by the TP type attribute. (R, W, setbycreate) (mandatory) (2 bytes)
+//
+//		Pptp Atm Uni Pointer
+//			PPTP ATM UNI pointer: This attribute points to an associated instance of the ITU-T G.983.2 PPTP
+//			ATM UNI. Refer to [ITUT G.983.2] for the definition of the target ME. (R, W, setbycreate)
+//			(mandatory) (2 bytes)
+//
+//		Max C Ell C Oncatenation
+//			Max cell concatenation: This attribute specifies the maximum number of ATM cells that can be
+//			concatenated into one PW packet in the upstream direction. (R, W, setbycreate) (mandatory) (2
+//			bytes)
+//
+//		Far End M Ax C Ell C Oncatenation
+//			Far-end max cell concatenation: This attribute specifies the maximum number of ATM cells that
+//			can be concatenated into one PW packet as provisioned at the far end. This attribute may be used
+//			for error checking of downstream traffic. The value 0 specifies that the ONU uses its internal
+//			default. (R, W, set-by-create) (optional) (2 bytes)
+//
+//		Atm Cell Loss Priority Clp Qos Mapping
+//			The value 0 specifies that the ONU uses its internal default. (R, W, setbycreate) (optional) (1
+//			byte)
+//
+//		Timeout Mode
+//			The value 0 specifies that the ONU uses its internal default. (R, W, setbycreate) (optional) (1
+//			byte)
+//
+//		Pw Atm Mapping Table
+//			(R,-W) (mandatory) (21N bytes, where N is the number of entries in the list)
