Question
Which of the following descriptions about multiplexing is correct? During byte interleaving multiplexing, the information payload and pointer bytes of each frame are interleaved and multiplexed according to the original values, and the segment overhead is also multiplexed accordingly.
Options

- BThe overhead in STM4 is newly integrated into only one set of overhead
- CThe overhead number in STM-4 is the same as that in STM-1
- DRandom generation of overhead in STM-4
