If a trail trace identifier (TTI) in the section monitoring (SM) layer is abnormal, the _____ alarm will be reported. (Enter only letters and special characters.)

Which of the following statements about incident optical power commissioning are true? (Choose all that apply.)

• A.By default, the incident optical power of each optical fiber is the special incident optical power (high power).
• B.If the output optical power of the downstream OA does not meet requirements in the case of the minimum gain, reduce the attenuation value of the upstream EVOA first to a value within the range required by incident optical power counters.
• C.If the output optical power of the downstream OA meets requirements in the case of the minimum pain, the upstream incident optical power cannot be lower than the incident optical power counters.
• D.If the output optical power of the downstream OA still does not meet requirements, increase the gain of the downstream OA.

Which of the following statements about OTN frame structure overheads is false?

• A.The FAS is located at the start position of the OTN frame structure.
• B.The value of FAS changes dynamically with different signals.
• C.The FAS is not scrambled.
• D.OTUk_LOF is generated when FAS framing fails.

Which of the following operations must be performed before you query bit errors and optical power on the NMS? (Choose all that apply.)

• A.Creating logical fibers
• B.Synchronizing NE data
• C.Setting the Enable NE Performance Monitor Time parameter
• D.Configuring data

For hybrid transmission of 100G-and-beyond and 10G signals, it is recommended that the optical power of
100G and beyond signals be higher than that of 10G signals but not higher than the single-wavelength nominal value of an OA board.

• A.FALSE
• B.TRUE
