質問 27
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.
- A. The SNCP service type is inconsistent with the service scenario requirements
- B. A small number of bit errors occur in the working channel
- C. Protection group 'Recovery Mode' is 'Non-Recovery'
- D. Manual switching, locking switching or forced switching commands are implemented artificially
- E. When the working channel is normal, the business needs to delay the "waiting for recovery time" and then switch from the protection channel to the working channel.
正解: A,C,D,E
