1. Regarding the description of OSS, which is wrong?

The network layer of the OSS is above the NMS, and the management of network element devices is generally implemented through the NMS.

The OSS system is mainly used to improve the work efficiency of equipment maintenance personnel

OSS system (Operation Support System) refers to a software system that provides operators with functions such as communication equipment performance management, inventory management, business management, and fault management.

The U2000 supports multiple northbound interfaces such as SNMP, TL1, XML, and DCORBA, which can realize rapid integration with the operator's OSS system.

Question 13 of 33

14. Which of the following statements about the main and backup channels of optical line protection is wrong?

"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.

"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).

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.

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.

Question 19 of 33

20. Which of the following description of the 100G mixed transmission system is wrong?

40G DQPSK and coherent signals will not affect each other without isolation band

10G starts from a short wavelength, and the isolation band can be filled with 40G DQPSK wavelength

The cost of mixed transmission is related to the number of transmission spans and the width of the isolation bandwidth, and has nothing to do with the FEC encoding method

Question 23 of 33

24. Which of the following statements about the delay test is wrong?

The delay is divided into the delay of the store-and-forward device and the delay of the bit-forward device. Huawei devices are all store-and-forward devices

The timing starts from the entry of the first bit of the data frame, and ends when the first bit of the data frame appears on the output terminal P. The time difference between the two is the delay of the bit forwarding device

During the delay test, the frame rate can be greater than the throughput

Question 24 of 33

25. 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?

Average single-wave optical power- 1dB

Average single-wave optical power- 2dB < single-wave optical power

Question 25 of 33

26. Which of the following descriptions about optical line protection is wrong?

Optical line protection is double-ended switching. In the case of a single optical fiber interruption, there will be no inconsistency in sending and receiving routes.

Use the OLP board to configure optical line protection. The RI1/T01 optical port of the 0LP board must be working, and the RI2/T02 optical port must be protection.

OLP board switching is only related to the received optical power

When protecting optical lines, use the dual-feed and selective-receiving function of the OLP single board to protect the line fibers between adjacent sites using separate routes

Question 29 of 33

30. Which of the following descriptions about electrical layer scheduling is wrong?

Inter-board cross-connect refers to the cross-connect configured between different boards. Inter-board cross-connection dispatches ODUk services between boards in a subrack through the backplane and centralized cross-connection boards.

Intra-board cross-connect refers to the cross-connect configured between different ports on the same board.

In the aggregation mode application scenario, it is necessary to cross within the board first, and then cross between boards.

All cross-connects need to be configured on the network management system.
