The rates of the SF64 and SL64 boards are both STM-64. Therefore, the two boards can be interconnected.

Manual configuration will clear data on the NE side.

NE A and NE B are adjacent NEs. If B3 and lower-order bit errors occur in the A->B direction and B1, B2, B3, and lower-order bit errors occur in the B->A direction, which of the following performance events are reported by NE A? (Multiple Choice)

Which of the following ITU-T recommendations defines the OTN frame structure?

A two-fiber ring topology consisting of three NEs is arranged in the counterclockwise sequence as A, B, and C. Services between A and C occupy the 48th VC-12 timeslot in the first VC-4 on the short path, and services between B and C also occupy the 48th VC-12 timeslot in the first VC-4 on the short path. In this case, which of the following is the subnet type of the ring protection?

Which of the following statements about the sequence of a signal flow between the SDH interface and the cross-connect unit is correct?

The Kl and K2 bytes can transmit APS switching signaling, and can also indicate that the multiplex section signal fails.

The number of 0DU2e signals multiplexed into an 0DU3 signal is the same as that of 0DU2 signals multiplexed into an 0DU3 signal.

If the overhead bytes pass through the backplane bus between two slots, the two slots are called paired slots. Paired slots implement automatic transparent transmission of overhead bytes, such as (),(), and (). This improves MSP switching performance and protects DCC communication with other NEs even if the SCC board on the local NE is offline. (Multiple Choice)
