NEW QUESTION 86
NE1, NE2, NE3, NE4, and NE5 form an MSP ring, and there is an STM-1 link between NE1 and NE3. An SNCP VC-4 service is created between NE1 and NE3.

NEW QUESTION 93
Which of the following statements about the configuration, testing and maintenance of IPA functions are correct? ()

IPA function is only applicable to Raman amplifiers, not to ordinary amplifiers

After the IPA function is successfully activated, when the amplifier board detects LOS, the optical power of its output port becomes safe optical power

Select “Configuration/IPA Management” in the function tree of the NE Manager to configure the IPA start delay value

When the fiber interruption is repaired and the IPA cannot be terminated, it may be because the IPA protection group is not configured with the “detection board”, only the auxiliary detection board is configured, and the auxiliary detection board reports an alarm that triggers IPA

The purpose of testing the IPA function is to verify that if any fiber is broken in the fiber path included in the IPA, the amplifier included in the IPA can be turned off. After the fiber is restored, the amplifier can be automatically turned on, and The power change is within 0.5dB.
