Chapter 4 Perform Node Acceptance Tests
Step 8 Change the administrative state of the drop BAND TX port related to the wavelength selected on the
tunable laser to OOS,MT.
(Optional) Connect a power meter to the proper 15xx.xs TX port on the front panel (the dual port

compared with the port where the tunable laser is connected). Verify that the physical optical power
value from that port is consistent with the value displayed on the Provisioning > Optical Chn >
Parameters tab for the proper CHAN TX power value, +/– 0.5 dB.
Verify the west AD-xC-xx.x (west-to-east) card:
Step 10
a. Display the west AD-xC-xx.x card in card view.
b. Click the Provisioning > Optical Chn > Parameters tabs.
Verify that the Power value of the CHAN TX port is higher than the default no-power value of

–35 dBm.
d. Display the east AD-xC-xx.x card in card view.
e. Click the Provisioning > Optical Chn > Parameters tabs.
Verify that the power value for the CHAN TX port is higher than the default no-power value of
f.
–35 dBm.
g. If the AD-xC-xx.x card is an AD-4C-xx.x card, a VOA (applied to all four channels) is installed
along the drop path and needs to be activated in Step h.

Remove the loopback on the west OSC-CSM card.
Step 13
In node view, click the Provisioning > WDM-ANS > Port Status tabs.

Click Launch ANS.
Step 15
Create a loopback on the east OSC-CSM card by connecting the OSC-CSM LINE RX and LINE TX

ports using a patchcord and 10-dB bulk attenuator.
Verify that the OSC link becomes active on the west OSC-CSM card. (The OSC termination must be
