Question 26

In the PW FPS scenario, which of the following descriptions about switching conditions and configurations is correct? (Multiple choice)

A.The switching condition depends on the OAM status of the working/protecting path

B.PW FPS can be configured asymmetrically (configured at one end and not at the other end)

C.PW FPS must be configured symmetrically (configured at both ends)

D.The replacement condition depends on the state of the APS protocol

Question 27

The interval between two adjacent pointer alignment events is at least () frames.

A.5

B.4

C.2

D.3

Question 28

In the fault handling scenario, which of the following descriptions about the common methods of fault location is wrong?

A.The instrument test method requires instruments

B.The loopback method does not affect the business

C.The signal flow analysis method has high requirements for maintenance personnel

D.Replacement method requires spare parts

Question 29

Which of the following commissioning ranges should the optical power of each single wave before combining (that is, the input optical power of the combining board) be within?

A.Average single-wave optical power- 2dB < single-wave optical power<average single-wave optical power+2dB

B.Average single-wave optical power- 2dB<single-wave optical power<average single-wave optical power+ 3dB

C.Average single-wave optical power- 1dB<single-wave optical power<average single-wave optical power+ 2dB

D.Average single-wave optical power- 1dB<single-wave optical power<average single-wave optical power+ 3dB

Question 30

Which of the following descriptions about the process of optimizing the abnormal line attenuation compensation are correct? (Multiple choice)

A.After receiving the alarm, the SOM obtains the OCh path corresponding to the alarm and adds it to the management path to be optimized.

B.The SCC board at the downstream site of the fault reports an alarm to the power detection unit (OA) of the first node through DCN communication, and the SC of the first node reports an alarm to the SOM.

C.According to the user's adjustment instruction, start the adjustment of the line attenuation for the OCh path, so that the output of the downstream optical amplifier reaches the normal value.

D.The downstream power detection unit (OA) detects that the line attenuation deviation exceeds the threshold, and reports an alarm to the SCC board of its own station.
