Alarm synthesis
The CT provides an alarm functionality that informs the operator on the severity of the
different alarms in the NE as well as on the number of current alarms. There are five different
alarm severity levels. In the CT these different levels are associated with colors.
• Red: Critical alarm (CRI)
• Orange: Major alarm (MAJ)
• Yellow: Minor alarm (MIN)
• Cyan: Warning alarm (WAR)
• Blue: Indeterminate (IND)
The meaning of each icon in the Alarm Synthesis is:
• CRI - Critical alarm
Synthesis of alarms that need immediate troubleshooting (typical: NE isolation)
• MAJ - Major (Urgent) alarm
Synthesis of alarms that need immediate troubleshooting
• MIN - Minor (Not Urgent) alarm
Synthesis of alarms for which an intervention can be deferred
• WAR - Warning alarm
Synthesis of alarms due to failure of another NE in the network
• IND - Indeterminate alarm
Synthesis of alarms not associated with the previous severities. Not operative.
Each alarm severity is represented by an alarm icon situated in the top left hand corner of the
view. These alarm icons are always represented on the different Equipment views so that the
operator is always aware of the alarms occurring in the system.
Furthermore the number in the alarm icon indicates the number of active alarms with that
specific severity.
Domain alarm synthesis area
This area contains the icons representing the alarms per domain. Each icon indicates the
number of alarm occurrences for each domain.
