7.5. ALL INPUT SIGNALS ARE TIMED WITHIN A RANGE OF +/- 1 LINE
FROM EACH OTHER BUT DELAYED 5 LINES FROM REFERENCE.
This example shows how a production switcher can be clean switched in and out of a 1200 series
SoftSwitch

or Embedded SoftSwitch

router used as a bypass router. Controlling the timing of the
incoming signals can allow all sources to be switched cleanly in the X1200 series router. At the same time
all the signals are in time to the production switcher. Finally, the production switcher can also be
presented to the bypass router within the range of the X1200 series router’s line synchronizer.
