TN55TQX+TN53NQ2 network element) -----TN53NQ2+TN55TQX (B network element) networking, the network element is a synchronous system, 10GELAN MAC transparent mapping mode, ALS function is turned on, and the connection with the router is normal. At this time, change the 55TQX 10GELAN mode of A network element to BIT transparent mapping mode, then what are the new alarms of A network element 53TQX (multiple choice)

• A.REMOTE_FAULT
• B.ODU2_LOFLOM
• C.ALS_ACTIVE
• D.REM_SF

Regarding the OTN system network-level protection switching test, which of the following statements is correct? ()

• A.In 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.OLP main and standby optical power abnormal threshold exceeds 5dB by default to perform switching, and the threshold range can be set -5~5
• C.The 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
• D.The ODUk-SNCP protection is superimposed on the OLP protection. In order to avoid secondary switching of the SNCP protection, the delay time can be set in the SNCP protection group

When relocating the OLA site (10G system), which of the following descriptions are wrong

• A.The relocation distance has changed, and the system dispersion needs to be re-evaluated
• B.The relocation distance has changed and the system signal-to-noise ratio needs to be reassessed
• C.There is no need to adjust the optical power of upstream and downstream sites in the network management during the relocation process
• D.The relocation distance has changed, and the optical power of the line needs to be reassessed
