During the normal operation of the network, the service channel protected by ODUK SNCP generates a condition for triggering protection switching, and the service has been automatically switched to the protection channel. When the fault of the working channel is eliminated, the service cannot be automatically restored to the working channel.

Which of the following operations need to be done before querying the bit error and optical power on the tube, otherwise the corresponding data cannot be queried?

Which of the following factors is related to pointer adjustment?

0TUK_LOF is a 0TUK layer alarm, which means the OTuk frame is lost, the FAS frame alignment is detected, and the alarm is reported when the frame is out of synchronization for 5ms. The alarm ends after the frame synchronization state is restored for 5ms.

The.0ptiX0SN 8800 T64 system is equipped with 4 PIU boards, and uses 1+1 hot backup mode to supply power to the system.

In the case of.1:1 protection, according to the provisions of G.8031, the source and sink devices must select the route during switching, so the APS protocol is required to coordinate the work.

1+1 protection means that when the sender sends service flows to both working and protected tunnels at the same time, the receiver selectively receives service flows according to the tunnel status or external commands.

The 1510 nm optical monitoring channel can be effectively amplified after passing through the EDFA.

The 1588V2 clock protocol can realize clock and time synchronization, and the working modes are OC, BC, TC.
