 */

/*
 *  8.2 Pause
 *
 *  The primitive "MTP-PAUSE" indicates to "Users" the total inability of
 *  providing the MTP service to the specified destination (see 7.2.6).
 *
 *  NOTE -  The signalling point is inacessible via the MTP.  The MTP will
 *  determine when the signalling point is again acessible and send MTP-RESUME
 *  indication.  The user should wait for such an indication and, meanwhile is
 *  not allowed to send messages on that signalling point.  If the remote peer
 *  user is thought to be unavailable, that condition may be maintained or
 *  cancelled at the local user's discretion.
 */

/*
 *  8.3 Resume
 *
 *  The primitive MTP-RESUME indications to the "User" the ability of
 *  providing the MTP service to the specified destination (See 7.2.6)
 *
 *  This primitive corresponds to the destination accessible state as defined
 *  in Recommendation Q.704.
 *
 *  NOTE -  When the MTP-RESUME indicaiton is given to each user, the MTP does
 *          not know whether the remote peer user is available.  This is the
 *          responsibility of each user.
 */

/*
 *  8.4 Status
 *
 *  The primitive "MTP-STATUS" indicates to the "Users" the partial inability
 *  of providing the MTP service to the specified destination.  The primitive
 *  is also used to indicate to a User that a remote corresponding User is
 *  unavailable and the cause for unavailability (see 11.2.7/Q.704).
 *
 *  In the case of national option with congestion priorities or multiple
 *  signalling link congestion states without prioritites as in Recommendation
 *  Q.704 are implemented, this "MTP-STATUS" primitive is also used to
 *  indicate a change of congestion level.
 *
 *  This primitive corresponds to the destination congested/User Part
 *  unavailable states as defined in Recommendation Q.704.
 *
 *  NOTE -  In the case of remote user unavailability, the user is responsible
 *          for determining the availability of this peer user.  The user is
 *          cautioned not to send normal traffic to the peer user because,
 *          while such peer is unavailable, no message will be delivered but
 *          each will result in a repeated "MTP-STATUS" indication.  The MTP
 *          will not send any further indications about the unavailability or
 *          availability of this peer user unless the local user continues to
 *          send messages to the peer user.
 */

/*
 *  8.5 Restart
 *
 *  When the MTP restart procedure is terminated, the MTP indicates the end of
 *  MTP restart to all local MTP Users showing each signalling point's
 *  accessibility or inaccessibility.  The means of doing this is
 *  implementation dependent (see 9/Q.704).
