第 31 号 Which of the following methods can be used to multiplex low-order ODUK to higher-order ODUk?

第 32 号 Both PDH and SDH have globally harmonized standards.

NO.33 Which of the following logic function blocks are involved in processing clock signals? (Multiple choice).

NO.34 For alignment; Indicates the starting position of VC-n in the corresponding AU or TU frame. * This way: The receiver can correctly remove the corresponding VC from STM-N, and then The VC and C packages are separated into separate low-rate signals, such as PDH, which means that the low-rate path signal can be dropped directly from the STM-N signal.
