Figure 15. Normal Operation Steps

The following steps are involved:

1. The operator presses a Source selector button for a Destination on a

control panel. The Panel button illuminates with a false tally.

2. The Panel sends a button press message to the Panel Server application.

3. The Panel Server interprets the message and sends a Source change

message for that Destination to the Router Control application.

4. The Router Control application interprets the message and sends a

crosspoint change message to the Router Matrix hardware.

5. The Router Matrix changes its crosspoint.

6. The Router Matrix sends a message reporting the new status of that

crosspoint to the Router Control application.

7. The Router Control application sends new Source status information

for that Destination to the Panel Server application.

8. The Panel Server application receives the new status and sends it to the

control panels.

9. All the affected control panels then change their button tally to reflect

the new status of the Destination. The false tally on the initiating control

panel changes to a true tally.

It can take up to four seconds to update all the control panel tally statuses

on a large Encore system. If the requested crosspoint change fails to occur,
