9.6.5. System diagnosis

The N-8000MI diagnoses the system condition, and provides its results at the contact output terminal as open
or closed contact. The system diagnosis is performed in a way that the N-8000MI connects the target
equipment via the network.
The contact output terminal is closed only when an abnormality has been detected.
Thereafter, its closed terminal opens when the N-8000MI judges the condition to be normal.
This function aims to diagnose the exchange's line status and the network status of the connected equipment.

Note
Diagnosis is performed at the set time intervals*. Therefore, the diagnosis results are not obtained in real time.
The system condition, even if a change occurs, cannot be detected in the intervals from a diagnosis to the
next diagnosis.

* Diagnosis results are renewed every 20 seconds or less.
