Dear friend!
Even if you can create logical fibers on NE2 and NE3, However, when creating a service trail, you need to issue the command on the NMS to the NE. In this case, the command fails to be issued.
There are two implementation modes:
1. Create a wavelength from NE1-NE2-NE3-NE4 to form an OCh trail.
2. Create a wavelength between adjacent sites. Then, the cross-connect boards of NE2 and NE3 forward ODUk signals to form an ODUk trail from NE1 to NE4.
Thank you!
