Hello,
Do we have same wavelength used in the circuit path (between source and destination nodes)?
Which type of circuit you are trying to create? (OCHNC or OCHCC)
Is this the first circuit you are trying to create?
If it's first circuit, are we sure that the pass-through nodes have IPC's created for the Express ?
Also, it will be great if you can show the complete details of the error message.
Thanks;
Ankur Sharma
