When a working PQ1 board is faulty, the device performs TPS protection switching. Which of the following statements about the switching process are correct? (Multiple Choice)

The cross-connect board detects that the PQ1 board is faulty through the board status bus.

If the protection PQ1 board is normal, the cross-connect board sends a switching message to the D75S corresponding to the faulty PQ1 board through the switching control bus.

The D75S board responds to the switching message by transferring services to the shared protection bus and stopping sending services to the faulty PQ1 board.

The protection PQ1 board receives and processes the services that are transferred from the D75S board to the protection bus to complete the protection switching.

Which of the following is the impact of changing the NE ID of OSN 3500 on the NMS?

NE communication is interrupted.

The NE time is not synchronized.

Which of the following statements about clock sources is incorrect?

If the standard SSM protocol is enabled, you need to set the clock source ID.

Internal clock sources have the lowest priority because of their low precision.

Generally, tributary clocks are not used as the clock sources of devices.

The same SSM protocol is selected for all NEs in a clock protection subnet.

If the standard SSM protocol is enabled, you need to set the clock source ID.
