      SYNTAX  Unsigned32

      DESCRIPTION
           "Pseudowire Identifier.  Used to identify the PW
            (together with some other fields) in the signaling
            session."

      DESCRIPTION
           "Pseudowire Index.  A unique value, greater than zero,
           for each locally defined PW.  Used for indexing
           several MIB tables associated with the particular PW.
           It is recommended that values are assigned contiguously
           starting from 1.  The value for each PW MUST remain
           constant at least from one re-initialization
           to the next re-initialization."

   PwIndexOrZeroType ::= TEXTUAL-CONVENTION
      DISPLAY-HINT "d"
      STATUS      current
      DESCRIPTION
           "This TEXTUAL-CONVENTION is an extension of the
            PwIndexType convention.  The latter defines a greater-
            than-zero value used to identify a pseudowire
            in the managed system.  This extension permits the
            additional value of zero.  The zero value is object-specific
            and MUST therefore be defined as part of the description of
            any object that uses this syntax.  Examples of the usage of
            zero might include situations where pseudowire was unknown,
            or where none or all pseudowires need to be referenced."

        - up(1):             Ready to pass packets.
        - down(2):           PW signaling is not yet finished, or

        - dormant(4):        The PW is not in a condition to pass
                             packets but is in a 'pending' state,
                             waiting for some external event.
        - notPresent(5):     Some component is missing to accomplish
                             the setup of the PW.  It can be
                             configuration error, incomplete
                             configuration, or a missing H/W component.

                             responsible for running the underlying PSN
                             is not in OperStatus 'up' state."

   PwCwStatusTC ::= TEXTUAL-CONVENTION
      STATUS      current

         "Indicates the status of the control word (CW) negotiation
          based on the local configuration and the indications received
          from the peer node.

          waitingForNextMsg(1) indicates that the node is waiting for
          another label mapping from the peer.







          sentWrongBitErrorCode(2) indicates that the local node has
          notified the peer about a mismatch in the C-bit.

          rxWithdrawWithWrongBitErrorCode(3) indicates that a withdraw
          message has been received with the wrong C-bit error code.

          illegalReceivedBit(4) indicates a C-bit configuration with
          the peer that is not compatible with the PW type.

          cwPresent(5) indicates that the CW is present for this PW.
          If signaling is used, the C-bit is set and agreed upon between
          the nodes.  For manually configured PW, the local
          configuration requires the use of the CW.

          cwNotPresent(6) indicates that the CW is not present for this
          PW.  If signaling is used, the C-bit is reset and agreed upon
          between the nodes.  For manually configured PW, the local
          configuration requires that the CW not be used.

          notYetKnown(7) indicates that a label mapping has not yet
          been received from the peer.

      DESCRIPTION
         "If set to a value other than zero, it indicates the desired

          noFrag(0) bit indicates that local configuration is for no
          fragmentation.

          cfgFragGreaterThanPsnMtu(1) bit indicates that the local node
          is set to fragment, but the fragmentation size is greater
          than the MTU available at the PSN between the nodes.
          Fragmentation is not done in this case.

          cfgFragButRemoteIncapable(2) bit indicates that the local
          configuration conveys the desire for fragmentation but
          the peer is not capable of reassembly.

          remoteFragCapable(3) bit indicates that the remote node
          is capable to accept fragmented PDUs.

          fragEnabled(4) bit indicates that fragmentation will be used
          on this PW.  Fragmentation can be used if the local node was
          configured for fragmentation, the peer has the capability
          to accept fragmented packets, and the CW is in use for this
          PW."
