9.2.3 Alarm signalling
If you do not have a central management system, you could perform alarm signalling with the alarm contacts
of the CN4 card nest.
Example
Suppose the following situation:
• On a remote Crocus SHDSL TT the configChanged alarm of the Crocus SHDSL G703 object is set to enabled
in the remoteAlarmMask. In other words: crocusShdslTtRpG703/remoteAlarmMask/configChanged = enabled.
• On a central Crocus SHDSL CV the remoteAlarm of the top object is set to enabled in the alarmContactHighMask.
In other words: crocusShdslTtRpG703/alarmContactHighMask/remoteAlarm = enabled.
• The high alarm contacts of the CN4 card nest are connected in a circuit with a light bulb.
Now the following happens:
Phase Situation Result
1 Someone changes the configuration of the
Crocus SHDSL TT.
2 On the Crocus SHDSL TT the configChanged
alarm is enabled in the remoteAlarmMask.
3 On the Crocus SHDSL CV the remoteAlarm
is enabled in the alarmContactHighMask.
4 The high alarm contacts of the CN4 card
nest close.
On the Crocus SHDSL TT the configChanged
alarm becomes active.
A remote alarm is sent to the Crocus
SHDSL CV.
The high alarm contacts of the CN4 card
nest close.
The light bulb lights up.
