140 NOC 78• 00 maintains a
health bit for each connection to a remote device. This bit is set to unhealthy if the input and/or output data is not updated within Health Time Out ms. However, during a switchover this time can vary up to ±50%.
For example, if the Health Time Out timer is set to 1500 ms:
-
The health bit is normally set to 0 (unhealthy state) if the input and/or output data is not updated within 1500 ms.
-
But during switchover, the Health Time Out can be between 750 ms and 2250 ms. This means that the unhealthy state may appear as early as 750 ms or as late as 2250 ms.
