A. he electrical monitoring is used, and the line quality is not good

B. he same NE user logs in to the NE at the same time

C. etwork element ID conflict

D. se optical monitoring, DCC mode setting is wrong

A. onfigure the time/time zone, you need to close the database

B. he dual-system active/standby association will automatically stop the network management of the standby site, and then automatically start the network management of the primary site

C. hen using the maintenance tool to do the dual-machine active/standby association operation, the initiator is the primary site, and the data will be copied from the initiator to the designated remote server

D. uring the process of associating/separating the primary and secondary sites, it is found that the VCS prompts a connection error

A. n the OTN bearer SDH multiplex section ring networking scenario, in order to avoid simultaneous switching of OLP protection and MSP protection, the delay time can be set in the MSP protection group

B. he power difference between the main and backup channels of the OLP protection group is more than 3dB by default, and the alarm is reported up, and the maximum can be set to 8dB

C. he ODUk-SNCP protection is superimposed on the OLP protection

D. LP main and standby optical power abnormal threshold exceeds 5dB by default to perform switching, and the threshold range can be set -5~5

A. ALSE

B. RUE

A. 2

B. 27

C. 0

D. 0011010

A. ALSE

B. RUE

A. efore the test, check whether the required test wires are complete, the type of connector and the applicability of the instrument and whether the connection is good

B. hen performing a 24-hour bit error test, ensure that the entire test process is free from external interference (including human factors and power supply conditions, etc

C. repare cotton swabs and alcohol, and pay attention to the cleaning of the connector at all times when testing the optical interface characteristics to ensure the accuracy of the test data

D. hen testing, be careful not to look directly at the optical transmitter interface, so as not to damage your eyes

A. he relocation distance has changed, and the optical power of the line needs to be reassessed

B. he relocation distance has changed, and the system dispersion needs to be re-evaluated

C. he relocation distance has changed and the system signal-to-noise ratio needs to be reassessed

D. here is no need to adjust the optical power of upstream and downstream sites in the network management during the relocation process
