                          corresponding objects in the x25OperTable.
                          This table contains the values as last set
                          by the administrator.  The x25OperTable

                          X.25 PLE.

                          Changing an administrative value may or may
                          not change a current operating value.  The

                          interface is restarted.  Some

                          immediately upon changing the administrative
                          table.  All implementations are required to

                          "This object reports the current status of
                          the circuit.

                          An existing instance of this object can only
                          be set to startClear, startPvcResetting, or
                          invalid.  An instance with the value calling
                          or open can only be set to startClear and
                          that action will start clearing the circuit.
                          An instance with the value PVC can only be
                          set to startPvcResetting or invalid and that
                          action resets the PVC or deletes the circuit
                          respectively.  The values startClear or
                          startPvcResetting will never be returned by
                          an agent.  An attempt to set the status of
                          an existing instance to a value other than
                          one of these values will result in an error.

                          A non-existing instance can be set to PVC to
                          create a PVC if the implementation supports
                          dynamic creation of PVCs.  Some
                          implementations may only allow creation and
                          deletion of PVCs if the interface is down.
                          Since the instance identifier will supply
                          the PLE index and the channel number,
                          setting this object alone supplies
                          sufficient information to create the
                          instance.  All the DEFVAL clauses for the
                          other objects of this table are appropriate
                          for creating a PVC; PLEs creating entries
                          for placed or accepted calls will use values
                          appropriate for the call rather than the
                          value of the DEFVAL clause.  Two managers
                          trying to create the same PVC can determine
                          from the return code which manager succeeded
                          and which failed (the failing manager fails
                          because it can not set a value of PVC for an
                          existing object).






                          An entry in the closed or invalid state may
                          be deleted or reused at the agent's
                          convence.  If the entry is kept in the
                          closed state, the values of the parameters
                          associated with the entry must be correct.
                          Closed implies the values in the circuit
                          table are correct.

                          The value of invalid indicates the other
                          values in the table are invalid.  Many
                          agents may never return a value of invalid
                          because they dynamically allocate and free
                          unused table entries.  An agent for a
                          statically configured systems can return
                          invalid to indicate the entry has not yet
                          been used so the counters contain no
                          information."

                          referenced from other objects which identify

                          It is impossible to know which other objects
                          in the MIB reference entries in the table by
                          looking at this table.  Because of this,
                          changes to parameters must be accomplished
                          by creating a new entry in this table and
                          then changing the referencing table to
                          identify the new entry.

                          Note that an agent will only use the values
                          in this table when another table is changed
                          to reference those values.  The number of

                          reference count will affect the writability
                          of the objects as explained above.

                          Entries in this table which have a reference
                          count of zero maybe deleted at the convence
                          of the agent.  Care should be taken by the
                          agent to give the NMS sufficient time to
                          create a reference to newly created entries.

                          Should a Management Station not find a free
                          index with which to create a new entry, it
