The new TN55ND2 board of the OSN8800 equipment was found to be unable to go online. Which of the following reasons are impossible?
- A . The master controller has a SWDL AUTOMATCH_INH alarm
- B . The master controller has a SWDL_PKG_NOBDSOFT alarm
- C . The master controller has a SWDL CHGMNG_NOMATCH alarm
- D . The master controller has a SWDL_BD WEAKMATCH alarm
Which of the following protections does N3EGS2 support?
- A . TPS
- B . PPS
- C . BPS
- D . DLAG
When using a dual slot line group MSP ring, in which of the following cases is the multiplex section overhead K bytes in the pass-through state?
- A . Cross-connect board abnormality
- B . Main control board abnormality
- C . The main control board is not in place
- D . When the multiplex section protocol controller state is pass-through
If a ROADM site adopts WSS+RMU configuration, which of the following impacts on SOM is wrong?
- A . If RMU is used locally to add wavelengths and has optical amplifiers, the OSNR value of the wavelength in the through direction detected by the SOM will deviate from the actual value
- B . There is an optical amplifier but no filter locally. The full-wave noise of the local optical amplifier affects the OSNR of the wavelength in the pass-through direction.
- C . The source and sink optical amplifiers of the optical cross-connect at this site must be in the same network element.
While expanding the existing network wave distribution system, which of the following performances do not need to be evaluated?
- A . PMD parameters of the link
- B . Optical power of OTU/OA
- C . BER of OTU before error correction at the receiving end
- D . Optical power flatness at the receiving end (with MCA)
Which of the following descriptions of the 1+1 protection features on the client side is wrong?
- A . OTU client optical layer dual transmission and selective reception
- B . Protect the OTU board and OCh fiber by occupying two wavelengths for protection and using different routes for transmission
- C . Working and protection wavelengths must be the same
- D . Long application time and wide protection range
After replacing the single master control, the new master control software is inconsistent with the previous faulty master control software. Which alarm may be triggered by the network element damage?
- A . SWD_PKGVER_MM
- B . SWDL_INPROCESS
- C . SWDL_CHGMNG_NOMATCH
- D . SWDL_PKG_NOBDSOFT

- B . The input optical power of the optical amplifier board does not need to be adjusted
- C . No further adjustment is required for the VOA on the relay wavelength
- D . The VOA of the upper wave does not need to be adjusted
