                          "This reports the status of a peer entry.
                          A value of valid indicates a normal entry
                          that is in use by the agent.  A value of
                          underCreation indicates a newly created
                          entry which isn't yet in use because the
                          creating management station is still setting
                          values.

                          The value of invalid indicates the entry is
                          no longer in use and the agent is free to
                          delete the entry at any time.  A management
                          station is also free to use an entry in the
                          invalid state.

                          Entries are created by setting a value of
                          createRequest.  Only non-existent or invalid
                          entries can be set to createRequest.  Upon
                          receiving a valid createRequest, the agent
                          will create an entry in the underCreation
                          state.  This object can not be set to a
                          value of underCreation directly, entries can

                          only be created by setting a value of
                          createRequest.  Entries that exist in other
                          than the invalid state can not be set to
                          createRequest.

                          Entries with a value of underCreation are
                          not used by the system and the management
                          station can change the values of other
                          objects in the table entry.  Management
                          stations should also remember to configure
                          values in the mioxPeerEncTable with the same
                          peer index value as this peer entry.

                          An entry in the underCreation state can be
                          set to valid or invalid.  Entries in the
                          underCreation state will stay in that state
                          until 1) the agent times them out, 2) they
                          are set to valid, 3) they are set to
                          invalid.  If an agent notices an entry has
                          been in the underCreation state for an
                          abnormally long time, it may decide the
                          management station has failed and invalidate
                          the entry.  A prudent agent will understand
                          that the management station may need to wait
                          for human input and will allow for that
                          possibility in its determination of this
                          abnormally long period.

                          Once a management station has completed all
                          fields of an entry, it will set a value of
                          valid.  This causes the entry to be
                          activated.

                          Entries in the valid state may also be set
                          to makeCall or clearCall to make or clear
                          X.25 calls to the peer.  After such a set
                          request the entry will still be in the valid
                          state.  Setting a value of makeCall causes
                          the agent to initiate an X.25 call request
                          to the peer specified by the entry.  Setting
                          a value of clearCall causes the agent to
                          initiate clearing one X.25 call present to
                          the peer.  Each set request will initiate
                          another call or clear request (up to the
                          maximum allowed); this means that management
                          stations that fail to get a response to a
                          set request should query to see if a call
                          was in fact placed or cleared before



Throop                                                         [Page 13]

                          valid state can not be set to makeCall or
                          clearCall.

                          The values of makeCall and clearCall provide

                          other devices which dynamically place calls
                          based on destination addresses may reject
