In the scenario where the non-convergence OTU processes OTN standard signals, both A and B are WDM sites. After receiving the OTUk_TIM alarm on the client side, the OTU board at station A sends the OTUk_BDI alarm to the upstream. When the TIM follow-up action is disabled, the alarm is no longer transmitted to the downstream. When the TIM follow-up action is enabled, an SF event is generated. The WDM side of the OTU board at station B reports the ODUk_PM_AIS alarm, and the ODUk_PM_AIS alarm is transmitted to the downstream. The client equipment reports this alarm.

After the WDM side of the OTU board at station B receives the OTUk_TIM alarm and the TIM follow-up action is disabled, the alarm is no longer transmitted to the downstream. When the TIM follow-up action is enabled, an SF event is generated. After the client side of station B processes the SF event, the client equipment reports the ODUk_PM_AIS alarm.

  1. True
  2. False

Answer(s): A



Which of the following statements about the electrical-layer overhead processing source function are correct?

  1. The OPUk performs client signal mapping, frequency adjustment, and rate adaptation in the transmit direction.
  2. The ODUkT calculates the BIP-8 and writes it into the TCMi.
  3. The OTUk calculates BIP-8 and writes it into SM, GCC0, FAS, and MAFS.
  4. the ODUkP calculates overheads such as BIP-8, PM, and GCC1/2.

Answer(s): C



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?

  1. Site C reports a ODU2_PM_LCK minor alarm.
  2. Site A reports a ODU2_PM_BDI minor alarm.
  3. Site A reports a ODU2_PM_LCK minor alarm.
  4. Site C reports a ODU2_PM_BDI minor alarm.

Answer(s): D



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.

  1. True
  2. False

Answer(s): A
