OTUk_DEG indicates OTUk signal degradation. Which of the following statements about the bit error detection mode are true? (Choose all that apply.)
- A. When bit errors are detected in Poisson mode, this alarm is reported after signal degradation or bit error threshold crossing occurs.
- B. When bit errors are detected in burst mode, this alarm is reported after signal degradation occurs.
- C. When bit errors are detected in burst mode, this alarm is reported after signal degradation or bit error threshold crossing occurs.
- D. When bit errors are detected in Poisson mode, this alarm is reported after signal degradation occurs.
Answer: B,C
Explanation:
In burst mode, an OTUk_DEG alarm is triggered when bit errors cause signal degradation, even if the error count threshold isn't crossed.
In burst mode, the alarm also occurs if the number of bit errors within the detection window exceeds the configured threshold.
