Question #54

Which of the following statements is wrong about the test items of IEEE 1588V2 time protection function?

A . The active and standby states of the clock board and cross-connect board on the OptiX OSN 8800 are related to each other. When performing a switchover test, it is recommended to only switch the cross-connect board or the clock board.
B . The active and standby states of the clock board and cross-connect board on the OptiX OSN 6800 are related to each other. When performing a switchover test, it is recommended to only switch the cross-connect board or the clock board.
C . Test the long-term stability of the time performance in PTP synchronization mode. The output time performance should be within ±1us.
D . For the long-term jitter test of the physical layer synchronization mode, a time analyzer with a GPS receiver is used to observe at the node for more than 8 hours. The test output time performance should be within ±1us.
