In 1588V2 time network planning, what matters should pay attention to? (Multiplce choice)
A . Networking mode: BC mode is recommended for the entire network
B . In practical applications, there may be a distance difference between the two directions of the optical fiber, but there is no need to compensate for this. 1588V2 will automatically calculate it based on the algorithm.
C . BMC algorithm must be started to prevent looping
D . 1PPS + TOD interface is more suitable for network internal transmission
