NO.167 Which of the following description of the process for optimizing the line attenuation compensation anomaly is correct? (Multiple choice)
- A. According to the user adjustment command, adjust the line attenuation of the OCh path to make the downstream light output reach the normal value.
- B. The SCC board at the downstream site of the fault reports the alarm to the power detection unit (OA) of the first node through DCN communication, and reports the alarm to the SOM on the SC of the first node.
- C. After receiving the alarm, the SOM obtains the OCh path corresponding to the alarm and adds it to the management path to be optimized.
- D. The downstream power detection unit (OA) detects that the line attenuation deviation exceeds the threshold and reports the alarm to its own SCC board.

NO.174 Which of the following statements are wrong about TE links? (Multiple Choice)
- A. The intelligent network element sends its own bandwidth and other information to other intelligent peers in the network through the LSA in the form of a trace. Provide teaching support for routing and planning.
- B. The verification of the TE link occurs before the control channel is established between adjacent nodes.
- C. The TE link path is a resource concept. It can be understood as an optical fiber with bandwidth information and protection attributes, but it does not correspond to the optical fiber. One fiber may correspond to multiple TE links.
- D. The TE link is flooded to the entire network by the LMP protocol. Each intelligent network element saves the TE link information of the entire network.
