문제6

During the normal operation of the network, the service working channel protected by the ODUk SNCP generates the conditions for triggering the protection switching. The service is automatically switched to the protection channel. After the working channel is faulty, the service cannot be automatically restored back to the working channel.

A. Artificially implemented manual switching, lock switching or forced switching commands

B. A small number of errors occur in the working channel

C. When the working channel is normal, the service needs to be delayed by the "waiting for recovery time" and then switched back to the working channel by the protection channel.

D. The SNCP type is inconsistent with the business scenario requirements.

E. The protection group "recovery mode" is "non-recovery"

정답: A,C,D,E
