This is getting complicated. The D75S board responds to the switch message by transmitting the service to the shared protection bus and stopping sending the service to the tyrant PQ1 board. Interesting.

Ah, I see. If the protection PQ1 board is normal, the cross-connection board sends a switching message to the D75S. Okay, got it.

I believe option D is correct because the protection PQ1 board processes the services to complete the protection switching.

I agree with you, Buffy. Option B also makes sense as the cross-connection board sends a switching message to the D75S.

Hmm, the cross-connect board checks the PQ1 board fault through the board status bus. That seems straightforward enough.

Wait, so the PQ1 board is oversized and the TFS protection is reversed? That's a new one. I better read up on that before I answer anything.

I believe option D is correct because the protection PQ1 board needs to receive and process the services to complete the switching process.
