NEW QUESTION # 26
The DWSS20 board supports grooming of 20-degree optical signals.
- A. TRUE
- B. FALSE
Answer: B
Explanation:
The DWSS20 board does not support grooming of 20-degree optical signals; it is designed for other signal types or degrees.

After subnetting, network traffic can be reduced, network performance can be improved, and management can be simplified.
- A. True
- B. False
Answer: A
NEW QUESTION # 28
Which of the following description of replacing the main control board is wrong?
- A. When the main control board has 1+1 hot backup, under normal switching conditions, the replacement of the main control board will not affect the scene.
- B. If the software version carried on the replaced main control board is higher than the device version, you need to clear the main control board first, and then downgrade the main board software to the same version as the device.
- C. If the software version locked on the replaced main control board is lower than the device version, you need to upgrade the software on the main control board to the same version as the device
- D. Removing and inserting the main control board will report BD_STATUS and COMMUN_FAIL alarms. After the new board goes online, these alarms need to be cleared manually.
Answer: D
NEW QUESTION # 29

Answer: A
NEW QUESTION # 31
Gain is an important index of fiber amplifier, and its unit is decibel.
- A. True
- B. False
Answer: A
NEW QUESTION # 32
The number of E1 frames that can be encapsulated in a CESoPSN message is determined by the "package loading time".
- A. True
- B. False
Answer: A
NEW QUESTION # 33
Which of the following statements about the main and backup channels of optical line protection is wrong?
- A. "Master-standby channel difference threshold (dB)" - used to set the difference between the main and standby optical ports of the board when the optical power difference reaches a certain value, it will be regarded as a signal failure (SF).
- B. When the difference in the optical power of the full backup exceeds the threshold, the optical switch will switch the service to the backup channel, and the set value supports query. Recommended setting is 5dB
- C. If the current optical power difference between the active and standby channels exceeds the "main and standby channel difference threshold (dB)", the system will initiate protection switching.
- D. "Initial Difference Between Active and Standby Channels (dB)"—the reference value used to set the optical power difference between the active and standby channels of the board.
Answer: B
NEW QUESTION # 34
When the PM segment of the ODUk generates seriously errored seconds, the network management will report the ODUk_PM_ES alarm.
- A. False
- B. True
Answer: A
NEW QUESTION # 35
In an OA-free system, the lower threshold of the receive optical power of a line board or the WDM side of an OTU board Is the optical module's receiver sensitivity plus 3 dB.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
In OA-free systems, where no optical amplifiers are used, the lower threshold of the receive optical power of a line board or the WDM side of an OTU board is indeed the optical module's receiver sensitivity plus 3 dB.
This ensures a safety margin for stable signal reception and alarm triggering. Without optical amplifiers, signal levels are more susceptible to attenuation, so maintaining this margin helps prevent degradation due to low optical power. HCIP-Transmission highlights this threshold as a standard parameter for optical power management in non-amplified systems.
NEW QUESTION # 36
Inconsistent FEC sending and receiving configurations will cause service interruption.
- A. True
- B. False
Answer: A
NEW QUESTION # 37
After starting the extended SSM protocol, in addition to judging the clock quality level and priority, the clock ID will also be judged. After the network element receives the clock signal with ID, if it is judged that the clock signal is sent by the station, the source is considered unavailable. In this way, the network element can still recognize the clock signal sent by itself even after being transmitted by multiple stations, preventing the formation of a timing loop.
- A. True
- B. False
Answer: A
NEW QUESTION # 38
Which of the following descriptions about the cross-connect board of the OSN 8800 T64 subrack is correct? (Multiple choice)
- A. XCT+SXM can support ODUO, level 1, 2, and 3 crossover.
- B. XCT+SXM can be used together to provide an ODUK crossover with a total capacity of 2.56Tbit/s.
- C. The enhancer rack can only be configured with UXCT+USXM or UXCT+USXH
- D. XCT+SXM can be regarded as a whole when working. If one board fails, the two boards will be switched together.
Answer: B,D
NEW QUESTION # 39
