• Question 132:

  Alarm signals on the PDH ports working at different rates differ. Which of the following are true?

  A. The T_ALOS alarm is reported when external signals are lost on an El electrical interface board.
  B. The P_LOS alarm is reported when external signals are lost on an E3 or E4 electrical interface board.
  C. The DOWN_El_AIS is reported when an El electrical interface board detects all "l"s in the downstream signal stream.
  D. The UP_E1_AIS is reported when an El electrical interface board detects all "l"s in the upstream signal stream.
  E. The PAIS is reported when an E3 electrical interface board detects all "l"s in signal streams.
  A. The T_ALOS alarm is reported when external signals are lost on an El electrical interface board.
  C. The DOWN_El_AIS is reported when an El electrical interface board detects all "l"s in the downstream signal stream.
  D. The UP_E1_AIS is reported when an El electrical interface board detects all "l"s in the upstream signal stream.
  E. The PAIS is reported when an E3 electrical interface board detects all "l"s in signal streams.

• Question 133:

  Which of the following are false about software installation on the PC that runs the NMS?

  A. Ensure that anti-virus software is installed on the PC.
  B. Game software can be installed after anti-virus software.
  C. You can access the Internet on the PC.
  D. Regular upgrade is not needed for the anti-virus software.
  A. Ensure that anti-virus software is installed on the PC.
  B. Game software can be installed after anti-virus software.
  C. You can access the Internet on the PC.

• Question 134:

  To test bidirectional performance data, the two ports of a data analyzer must be set to simultaneously receiving and transmitting data. Otherwise, you cannot obtain the required data.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 135:

  NG-SDH equipment can be used for complex networking. Which of the following statements about protection or service configuration are true?

  A. On a network where MSP rings and SNCP rings share fiber resources, all timeslots can be configured for SNCP services, because SNCP service configuration is flexible and SNCP services does not require special overheads to transmit protocol information.
  B. Two SNCP rings are tangent. The source and sink work in dual transmission and selective receiving mode. The line boards corresponding to the tangent node are configured with bidirectional pass-through services. Given the preceding configurations, services can be protected after a fiber cut.
  C. Two MSP rings are intersected. To prevent service interruption upon failure of one intersecting node, you need to configure an SNCP service pair on an intersecting node to support dual transmission and selective receiving.
  D. OSN equipment does not support logical systems. You do not need to specify master and slave nodes during DNI service configuration.
  C. Two MSP rings are intersected. To prevent service interruption upon failure of one intersecting node, you need to configure an SNCP service pair on an intersecting node to support dual transmission and selective receiving.
  D. OSN equipment does not support logical systems. You do not need to specify master and slave nodes during DNI service configuration.

• Question 136:

  If equipment power is configured with 1+1 protection you can replace the PIU board without cutting off the supply from the DC power distribution unit.

  A. TRUE
  B. FALSE
  B. FALSE

• Question 137:

  MSP and SNCP can coexist on a complex network. Which of the following statements are true?

  A. Some timeslots have double protection.
  B. By default, an SNCP switchover takes a shorter time than an MSP switchover.
  C. Two SNCP switchovers will occur if SNCP holdoff time is not set.
  D. Frequent switchovers do not affect services.
  A. Some timeslots have double protection.
  B. By default, an SNCP switchover takes a shorter time than an MSP switchover.
  C. Two SNCP switchovers will occur if SNCP holdoff time is not set.

• Question 138:

  What is the purpose of setting SNCP holdoff time?

  A. An SNCP switchover takes a longer time than an MSP switchover.
  B. SNCP switching is reliable and efficient.
  C. To prevent a second SNCP switching
  D. None of the above
  C. To prevent a second SNCP switching
