frAtmIwfConnIndexNext OBJECT-TYPE
SYNTAX Integer32 (0..2147483647)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This object contains an appropriate value to be
used for frAtmIwfConnIndex when creating entries
in the frAtmIwfConnectionTable. The value 0
indicates that no unassigned entries are
available. To obtain the frAtmIwfConnIndexNext
value for a new entry, the manager issues a
management protocol retrieval operation to obtain
the current value of this object. After each
retrieval, the agent should modify the value to
the next unassigned index."

DESCRIPTION

Relay/ATM interworking connection."
::= { frAtmIwfMIBObjects 2 }
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
Rehbehn, et al. Standards Track [Page 14]

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."

"The table row may be created with

To activate a connection entry, a valid connection
descriptor MUST be established in the
frAtmIwfConnectionDescriptor object.
This object is set to 'destroy(6)' to delete the
table row. Before the table row is destroyed, the
OperStatus/AdminStatus of the corresponding
endpoints MUST be 'down(2)'. The deactivation of
the ATM endpoint MAY occur as a side-effect of
deleting the FR/ATM IWF cross-connection table
row. Otherwise, 'destroy(6)' operation MUST fail
(error code 'inconsistentValue')."
