3.5.1.1 Time diagram: Changeover between preferred and redundant line
i
Time diagrams: Times are not shown to scale.
Example: Line 1 is set as preferred line.
Changeover to line 2
if line 1 has failed Switching back to
line 1 (normal operation with delay on release) Switching back to line 1
(if line 2 has failed)
