     The following termination causes relate to ISDN, asynchronous, and
     synchronous connections:

             Termination Cause                     Description

      Admin Reset                     A reset S0 command was issued on that
                                      port.
                                      The incoming call is for a dialback
      Callback -User Requested        user, the PortMaster terminated the
                                      connection to call back the user.
      Host Request                    The user requested to reset the port.

      Host Request (PMD)              The user requested to reset the port
                                      using the in.pmd service.

      Idle Timeout                    The user was disconnected by the idle
                                      timer.
                                      The user did not respond to the
      Login Timeout                   login: prompt in the time specified
                                      by the login timer.
                                      The session terminated when the local
                                      modem dropped the Data Carrier Detect
                                      (DCD) signal for some reason. For
                                      example:

      Lost Carrier                       * The remote user or modem hung up
                                           the telephone. No problem
                                           exists.

                                         * The line was dropped or received
                                           interference too severe for the
                                           modem to recover from.
      Lost Service-Interface Down     The logical interface is down.

      Lost Service-Interface Error    An unspecified interface error
                                      occurred.

      Lost Service-LMI                The PortMaster lost connectivity to
                                      the Frame Relay switch.
                                      The PortMaster has run out of network
      Lost Service-No Netbufs         buffers. Contact Lucent Remote Access

      NAS Request- Modem Config       The PortMaster 3 modem initialization
      Complete                        is complete.
                                      The PortMaster sent a specified
      NAS Request- PPP Maximum        number of PPP packets with no
      Retransmissions                 response, and has determined that the
                                      remote PPP stack has disappeared.

      Port Error- Exceeded LAPM       The PortMaster exceeded the Link
      retrans limit                   Access Procedure for Modems (LAPM)
                                      retransmission limit.
                                      The PortMaster either exceeded the
                                      Microcom Networking protocol (MNP)
      Port Error- Exceeded MNP        retransmission limit (12 retries) or
      retrans limit                   the idle timer expired waiting for
                                      Link Request (1 second) or Link
                                      Acknowledge (5 seconds).

      Port Error-PPP could not send   The PortMaster was trying to send PPP
                                      and could not for an unknown reason.
                                      The PortMaster is receiving its own
      Port Error- PPP loop detected   data, possibly due to a CSU/DSU
                                      malfunction.

      Port Error- Spurious Interrupts (DCD) signal was toggling more than
                                      10,000 times in a 1-second window, so
                                      the PortMaster reset the port.
                                      The port is set for network
      Port Error-Wrong Type           connections only, and a login user
                                      attempted to connect.

      Unavailable                     connect because the host did not
