Which of the following is the client-side logical port of a board in standard mode?

A. ODUkLP-n

B. RX/TX-n

C. ClientLP-n

D. n(Nn/OUTn)-OCH:1-ODUk:m-ODUp:q

Which of the following trails can be configured on the NMS?

A. OTS

B. ODUk

C. client

D. OCh

Which of the following statements about the Service Package is incorrect?

A. You can configure service package in two modes. One is to configure boards in batches, and the other is to configure each board.

B. Service package enables one-click configuration of typical services by issuing multiple configuration commands in batches, facilitating product deployment commissioning and reducing maintenance costs.

C. The Service Package can configure the working mode, service type, cross-connection, and port type in batches.

D. Currently, Service Package is available to the TOA, TOX and TSC boards.

A and C are WDM OTM sites, and B is a regeneration site. If the ODU2_LCK signal is inserted at site A, which of the following statements are correct?

A. Site C reports a ODU2_PM_LCK minor alarm.

B. Site A reports a ODU2_PM_BDI minor alarm.

C. Site A reports a ODU2_PM_LCK minor alarm.

D. Site C reports a ODU2_PM_BDI minor alarm.

In the scenario where the non-convergence OTU processes OTN standard signals, both A and B are WDM sites. The OTU at station A accesses four channels of R_LOS signals on the client side. After being processed in the middle part and on the WDM side of the OTU at station A, the alarm signals are then sent to station B. The ODUk_PM_AIS alarm of the corresponding channel is generated in the middle part of station B. The ODUk_PM_AIS alarm is detected in the client device.

A. True

B. False

Which of the following methods can be used to analyze faults in the NG WDM system?

A. Loopback

B. Service Signal Flow Analysis

C. RMON

D. Replacement

MPLS APS is a network protection mechanism. It implements service switching by using the MPLS OAM detection function.

A. True

B. False

Which of the following is not a PW APS switching condition?

A. A warm reset is performed on the board.

B. The board software is faulty.

C. MPLS_PW_SF

D. A cold reset is performed on the board.

Which of the following statements about AU pointers are correct?

A. The root cause of the AU pointer justification is that the clocks of the upstream and downstream stations are not synchronized.

B. AU_PTR indicates the position of the J0 byte.

C. If the receive end detects that the H1H2 bytes are "1", the local end generates the AU-AIS alarm.

D. The value of the AU-PTR pointer is placed in the last 10 bits of the H1 and H2 bytes. Therefore, the valid value of the AU-PTR pointer is 0~1023.

Which of the following is not a precaution after board replacement?

A. Record the settings of jumpers and DIP switches on the board.

B. For functional units that have backups, check whether the switchover is normal.

C. Check the indicator blinking status of the board and ensure that the board works properly.

D. Ensure that no abnormal alarm.

The troubleshooting methods that can be used to separate external faults are:

A. Configuration Data Analysis

B. Meter Test

C. Replacement

D. Loopback

For the MSTP equipment, the pass-through mode is used for VC-4 services by default, and the termination mode is used for VC12/VC3 services by default.

A. True

B. False
