Release the forced protection switch.•
This is the UPSR ring topology in the lab setup as seen from the CTC network view:
Check Circuit Integrity
Complete the steps in the instructions provided in order to check the circuit integrity:
From the CTC network view confirm all circuits are in an Active state.
If any circuits are in an Incomplete state then do not continue. Refer to the Best Practices When
Configuring Circuits on the ONS 15454 document in order to resolve issues with circuits in an
Incomplete state.
