Step 7 Clear the Force switches.
•To clear 1+1 Force switches, complete the “Clear a 1+1 Force Switch” task on page 11 .
•To clear Path Protection Force switches, complete the “Clear a Path Protection Force Switch” task on page 11.
Step 8 Once the card is placed in service and is receiving traffic, reset the card’s physical receive power level threshold in CTC:
a.
b.Click the Provisioning > Threshold tabs.
c.Click the Physical radio button.
