        External AIS - is an Alarm Indication Signal associated
        with a maintenance alarm detected on a defective 
        maintenance span, that is transmitted in the direction 
        of the defect as a substitute for normal signal. 
        The purpose is to show the downstream  entities that 
        a defect has been identified and to prevent other 
        maintenance alarms consequent to this first defect.
        External AIS bit stream is represented by an all 1's 
        Ref - ITU-T Rec. M.20 sec. 5.4.2 a 
        External RAI - is a Remote Alarm Indication signal 
        that is transmitted upstream from an entity that has 
        detected defects persisting long enough to constitute 
        a received signal failure. Its purpose is to report in 
        the backward direction that there is an interruption 
        of service in the forward direction.
        The forward direction is from the originating end of
        the alarm to the remote end.
        The backward direction is from the remote end to the
        orginating end of the alarm.
        Ref - ITU-T Rec. G.704 section 
              I.366.2 - ANNEX N
        External Connection AIS - is a Alarm Indicating Signal 
        transmitted in the downstream direction from the AAL 
        type 2 connecting point that first detects a defect 
        affecting the AAL type 2 connection; this includes 
        defects indicated by lower layers.
        Ref - ITU-T Rec. I.610 sec 
        External Connection RDI -  is a signal transmitted upstream 
        by an AAl type 2 endpoint that is in an alarm state as the 
        result of having received an AAL type2 connection AIS or 
        having detected a defect that affects the AAL type2 
        All ATM alarm definitions are specified in I.610 
        (ITU standard).
