Method used to verify the consistency between physical fiber connections and logical fiber connections on Metro 1000


1. The Metro 1000 V2 does not support query for received J0 bytes. You can change the number of J0 bytes to be transmitted at the local end to be different from the number of J0 bytes to be received at the peer end, and then check whether the J0_MM alarm is reported.
2. You can also insert an MS_AIS alarm and check whether the peer end reports the MS_AIS alarm. Exercise caution because this operation will interrupt services.

Reason for a WAVELEN_OVER alarm reported on the WMU board when physical and logical fiber connections are inconsistent
When physical and logical fiber connections are inconsistent, the wavelength locking function triggers a false wavelength adjustment. As a result, a WAVELEN_OVER alarm is reported.

Method used to query intra-NE fiber connections on the NMS
You can query the logical fiber connections between optical NEs in the main view of the U2000. On the main topology of the U2000, double-click the desired optical NE to display the status diagrams of the NE. Select the signal flow diagram. Then you can query the logical fiber connections between boards of the optical NE.
