Step 2
Click the Provisioning > Line > Wavelength Trunk Provisioning tabs.
Step 3 In the Wavelength field, view the provisioned card wavelength.
Step 4
If you have access to the site, compare the wavelength listed on the card faceplate with the provisioned wavelength. If
you are remote, compare this wavelength with the card identification in the inventory:
a) In node view (single-shelf mode) or shelf view (multishelf mode), click the Inventory tab.
b) Locate the slot where the TXP or MXP card is installed and view the card wavelength in the name.
Step 5 If the card was provisioned for the wrong wavelength, double-click the card in node view (single-shelf mode) or shelf
view (multishelf mode) to open the card view.
Step 6 Click the Provisioning > Line > Wavelength Trunk Provisioning tabs.
Step 7
In the Wavelength field, click the drop-down list and choose the correct wavelength.
Step 8 Click Apply.
If the wavelength does not appear because the wavelength band of the card, either C or L, differs from the band that was
provisioned in CTC, complete the following steps:
a) In the Wavelength field, click the drop-down list and choose First Tunable Wavelength.
b) Click Apply.
c) In the Wavelength field, click the drop-down list and choose the correct wavelength.
d) Click Apply.

The alarm is cleared when the laser wavelength locker detects a lock condition during which the laser is
steadily tuned at the required wavelength.
