1. NG-SDH equipment, if there is no alarm on the current port, you can set the alarm inversion on the port. The mode is manual recovery mode.

2. Now NE1 and NE2 form a chain link network. E1 business is configured between NE1 and NE2.
One day NE1 receives NE2 fiber interruption (negative direction fiber is not broken), then which of the following alarms will NE2 report? (Multiple choice)

3. For the extended SSM protocol, clock ID setting principles. Which of the following statement is true? (Multiple choice)

4. When SDH equipment for single station test, you need to check the hardware of single station: including cabinet, sub-rack installation check, power terminal resistance measurement, cable laying normative check, board visual inspection, and part board of dial code jumping Line inspection.

5. In an actual ASON network, if NE1 to NE3 need to create an intelligent business, known the NE1 reaches NE3 through NE2 and the LSP is optimal. The LSP establishment process requires the following steps:
(1)NE1 receives the loopback message and saves the related information. And then reported to web master and the LSP is successfully created.
(2)NE1 calls CSPF algorithm, to obtain the control topology and the business topology according to the OSPF-TE protocol convergence. To calculate the most suitable business route, it is assumed that is NE1-NE2-NE3;
(3) Web master sends commands to NE1 to create a two-way VC4 business from NE1 to NE3.
(4) NE1 sends the message to IIE = through the PSVP-TE signaling protocol according to the calculated route, requests reservation of resources and establishes cross-connection;
(5) After NE3 completing the cross-connection establishment, the message back to the NE2;
(6)NE2 sends a message to NE3 through the RSVP-TE signaling protocol, requesting reservation of resources and establishment of cross-connection;
(7) NE2 sends a message back to NE1.
Which of the following order is correct?

6. Which of the following is the TU-PTR pointer value in the case of no frequency difference and phase difference?

7. Which of the following protocols is used to set up and delete an LSP in an ASON network?

8. Outbound subnet business refers to the physical topology is the ring chain, the business node from the ring to reach the node on the chain.

9. Which of the following description about the equipment loopback operation is wrong?

10. SNCP ring and SNCP ring intersection networking, any one intersection point network elements failure or any two fiber-broken, the business can be protected.

11. TU pointer adjustment is converted from the AU pointer adjustment.

12. SNCP protection mechanism is the "Received double election." For the SNCP ring and SCNP ring, cross-ring business in the tangent point needs to be selected and then dual-transmitter, in theory, for the two-way cross-ring business at the tangent point, we have to configure four pairs of dual-transmitter,4 pairs of selective transceiver business.

13. For the description of the TU pointer, which of the following statements are true? (Multiple choice)

14. Which one of the following is the default network elements user name when creating network elements on the OptiX OSN 3500 line single station measurement using the NMS network management (U2000)?

15. Which of the following are possible reasons of TPS protection switching failure? (Multiple choice)

16. For NG-SDH device, which of the following belongs to the causes of DOWN_E1_AIS alarms? (Multiple choice)

17. Which of the following belongs to the influence and harm of discrete business? (Multiple choice)

18. SNCP and MSP protection co-exist, part of the time slot at the same time enjoy double protection. When the optical fiber is interrupted, this will often cause secondary switching. In order to avoid secondary switching, you need to set SNCP delay time.
Which of the following is reasonable about the delay time setting?

19. The following statement about error code, which is correct? (Multiple choice)

20. About clean dust screen, which is correct? (Multiple choice)
