A system Data Distribution alarm is generated if the number of SDS data distribution errors exceeds the Minor alarm threshold. By default, the Minor alarm threshold for Data Distribution errors is 0, so an alarm will be present whenever there is one or more distribution errors. The alarm is cleared when the number of errors no longer exceeds the threshold.
SDS data distribution errors are typically caused by the following error conditions:
the device associated with the data distribution error is not programmed properly on the remote controller
a required feature or feature option is not enabled on the remote controller.
the network connection to the remote controller is down (results in a large number of errors).
Data Distribution alarms are displayed in the Alarms Details forms. There are two alarm categories:
The system generates a System Data Sharing Alarm after the first data sharing error occurs.
Category Name: SDS Sys Data Alarm
Alarm Level: Minor
Thresholds
Minor alarm threshold: >0 %
Major alarm threshold: not applicable
Critical alarm threshold: not applicable
The system generates a minor alarm after the number of updates in the SDS Shared Data Updates form exceeds 200, and a major alarm after the number exceeds 10000. For both alarm categories, you clear the alarm by resolving the pending updates. After the number of errors falls below the threshold level the system will clear the alarm.
Category Name: SDS Usage Alarm
Alarm Level: Minor and Major
Thresholds
Minor alarm threshold: > 1 % (200 to 9999 updates in the table)
Major alarm threshold: > 50% (10000 to 20000 updates in the table)
Critical alarm threshold: not applicable
The maximum number of updates that the form can contain is 20000. After the 20000 limit is reached, the system will prevent you from making any further changes to the records in the shared forms. In addition, any changes to telephone user data through the telephone user interface (TUI) will not be shared between the primary and secondary controllers.
Before the system will allow you to start making changes again, you must reduce the number of updates in the SDS Shared Data Updates form (see Resolving Pending Updates or Errors).
