Alarm Masking
Maintenance engineers can configure alarm masking on terminals so that terminals detect only alarms that are not masked. This function helps users ignore the alarms that do not need to be displayed.
Figure 1 illustrates principles of the alarm masking function.
Alarm masking has the following characteristics:
- Alarm masking is terminal-specific. Specifically, alarms that are masked on a terminal can still be received normally by other terminals.
- A terminal can be configured with an alarm masking table to control its alarm information.
