frAtmIwfConnectionEntry OBJECT-TYPE
	SYNTAX  FrAtmIwfConnectionEntry
	MAX-ACCESS not-accessible
	STATUS  current
	DESCRIPTION
		"The FrAtmIwfConnectionEntry provides an entry for
		an interworking connection between a frame relay
		PVC and one or more ATM PVCs, or an ATM PVC and
		one or more frame relay PVCs.  A single frame
		relay PVC connected to a single ATM PVC is
		referred to as a `point-to-point' connection and
		is represented by a single row in the FR/ATM IWF
		Connection Table.  The case of a single frame
		relay PVC connected to multiple ATM PVCs (or
		single ATM PVC connected to multiple frame relay
		PVCs) is referred to as a `point-to-multipoint'
		connection and is represented by multiple rows in
		the FR/ATM IWF Connection Table.

		The object frAtmIwfConnIndex uniquely identifies
		each point-to-point or point-to-multipoint
		connection.  The manager obtains the
		frAtmIwfConnIndex value by reading the
		frAtmIwfConnIndexNext object.

		After a frAtmIwfConnIndex is assigned for the
		connection, the manager creates one or more rows
		in the Cross Connect Table; one for each cross-
		connection between the frame relay PVC and an ATM
		PVC. In the case of `point-to-multipoint'
		connections, all rows are indexed by the same
		frAtmIwfConnIndex value and MUST refer to the same
		frame relay PVC or ATM PVC respectively.  An entry
		can be created only when at least one pair of
		frame relay and ATM PVCs exist.

		A row can be established by one-step set-request
		with all required parameter values and
		frAtmIwfConnRowStatus set to createAndGo(4). The





		Agent should perform all error checking as needed.
		A pair of cross-connected PVCs, as identified by a
		particular value of the indexes, is released by
		setting frAtmIwfConnRowStatus to destroy(6). The
		Agent may release all associated resources. The
		manager may remove the related PVCs thereafter.
		Indexes are persistent across reboots of the
		system."
