You may inhibit alarms and events resulting from changes to normal or off-normal states. Normal and off-normal states for a connection are determined by alarms that are related to the following:

  • Modem failure (connection lost, unable to establish connection).

  • Configuration errors (cannot assign device).

  • Dial-up line communication errors.
