Default section alarm mapping
An alarm affects a section if:
− the alarm flag “isTrafficAffected” is TRUE and
− the alarm NE id and the section NE id match and
− the alarm TPAddress and the section slot, subslot and port number match,
or
− the alarm flag “isTrafficAffected” is TRUE and
− the alarm NE id and the section NE id match and
− the alarm TPAddress is a NullAddress and
− the alarm SbuAddress and the section slot number match.
The first “if” statement is used with traffic alarms like LOS and AIS Received. The second statement is used for general unit alarms like Unit not assigned, No application software, Loss of Signal on SDH Clock source.
