NEW QUESTION # 373
Which of the following descriptions about the process of optimizing the abnormal line attenuation compensation are correct? (Multiple choice)
- A. 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.
- B. 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.
- 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. After receiving the alarm, the SOM obtains the OCh path corresponding to the alarm and adds it to the management path to be optimized.
Answer: B,C,D

NEW QUESTION # 376
Which of the following statements about overhead bytes is wrong?
- A. A1 and A2 are framing bytes. These bytes are used to separate STM-1 frames in the signal stream
- B. JO is the regenerator section trace byte. This byte is used to repeatedly send the segment access point identifier so that the receiving end can verify its continuous connection with the designated sending end
- C. B1 is Bit Interleaved Parity-8 (BIP-8). This byte is used to monitor the regenerator part layer for bit errors
- D. E1 and E2 are wired bytes. These bytes are used to provide voice channels for order line connections.
Answer: A
NEW QUESTION # 377
Which of the following descriptions about the OTU board is correct? (Multiple choice)
- A. The single board in standard mode is easy to operate and can reduce maintenance costs.
- B. For a single board in compatibility mode, when configuring a cross-connect, the user does not need to care about the logical ports inside the board.
- C. Standard mode has fewer path hierarchies than compatibility mode.
- D. For a single board in standard mode, on the network management, only the service mapping path under the channel or physical port is displayed, and all ODU layers are directly displayed under the physical port.
Answer: A,C
NEW QUESTION # 378

NEW QUESTION # 379
What should be paid attention to when commissioning a hybrid transmission system of 100G and 10G? (Multiple choice)
- A. It is recommended that the optical power of the 100G signal should be higher than that of the 10G signal, but not higher than the single-wavelength nominal value of the optical amplifier board.
- B. In order to accurately measure the optical power of 100G wavelength, a spectrum analyzer or a MAC board must be used for commissioning
- C. For a hybrid transmission system with dispersion compensation, its dispersion compensation requirements should be consistent with those in 10G non-coherent systems
- D. Pay attention to the mixed transmission spectrum, the spectrum of the 100G signal is relatively wide, and it looks lower than the 100G signal in the spectrum, but the actual optical power is equivalent
Answer: A,B,C,D
