This object contains an appropriate value to be used for
coifccCcIndex when creating entries in the
coifccCrossConnectTable. The value 0 indicates that no
unassigned entries are available. To obtain the coifccCcIndex
value for a new entry, the manager issues a management protocol
retrieval operation to obtain the current value of this object.
The agent will modify the value to the next unassigned index,
when a new row is created in coifccCrossConnectTable with
coifccCcIndex value equal to the current value of this object.
After deletion of a row in coifccCrossConnectTable the agent
will determine through its local policy when its index value
will be made available for reuse.
