A fiber can no be created between the port 2 of the ND2 board and port M12 of the M40 board in the signal flow diagram.
Appears the following error message (Figure 1):
The parity wave band of the source does not match the parity wave band of the sink, Error Code: 41909
The WDM interface configuration can be checked in the following menu of the NE explorer:
NE Explorer > Configuration > WDM interface > Advance Attributes
When the configuration was checked there was an error in the planned frequency of the port 2 of the ND2 board, it was 196,05 (Figure 2).
In order to create the fiber between the port 2 of the ND2 board and port M12 of the M40 board, the configured frequency in the port 2 of the ND2 board must be 194,0.
After made this change the fiber can be created.
Is necessary to check the configuration of the WDM interface of the ND2 Line Unit.
Before to create the fibers in the Signal Flow Diagram, configure all parameters of the involved boards (like OTU, MUX, etc).
