Note: The system will not attempt to restore any LCD to its pre-test
state. The LCDs will be OFF at the end of the test, with features in the
same state as before the test. A background audit restores all feature
indicators at its next occurrence (audit intervals are switch and load
related). Any newly activated features after termination of the test
procedure will be indicated normally. No incoming calls can be
received for the duration of a Station Ringer Test. In order to prevent
prolonged line blockages, this test is limited to a 7 minute interval
after which the line will automatically be restored to normal and the
test terminated.
