Chapter 4 Perform Node Acceptance Tests
NTP-G47 Perform the Line Amplifier Node with OSCM and OSC-CSM Cards Acceptance Test
Step 12 Display the OPT-BST in card view.
Step 13 Click the Provisioning > Optical Line > Parameters tabs. Verify that the power value on Port 2
(Out Com) is equal to the optical power from the tunable laser or TXP_MR_2.5G card (measured in
Step 10) +/– 1 dBm.
Step 14 If an OPT-PRE card is installed on the side opposite the OSC-CSM, complete the “DLP-G80 Verify the
OPT-PRE Amplifier Laser and Power” task on page 4-41. If not, continue with Step 15.
Step 15 Display the OSC-CSM card in card view.
Step 16 Click the Provisioning > Optical Line > Parameters tabs and locate the Port 3 Power value. Verify
that the value is higher than –30 dBm. If the power value is not higher than –30 dBm, check your
connections and clean the fibers using the “NTP-G115 Clean Fiber Connectors” procedure on
page 13-25. If this does not change the power value, consult your next level of support.
Step 17 If an OPT-PRE card is installed on the same side as the OSC-CSM, complete the “DLP-G80 Verify the
OPT-PRE Amplifier Laser and Power” task on page 4-41. If not, continue with Step 18.
Step 18 Complete the “DLP-G79 Verify the OPT-BST Amplifier Laser and Power” task on page 4-40 for the
OPT-BST card.
Step 19 Disconnect the TXP or tunable laser from the OPT-BST card.
Step 20 Remove the loopback fiber on the OSC-CSM card.
Step 21 Delete both OSC channels. See the “DLP-G186 Delete an OSC Termination” task on page 10-41.
Step 22 Complete the “NTP-G37 Run Automatic Node Setup” procedure on page 3-83 to restore the original
configuration.
Step 23 Create the OSC channels using the “NTP-G38 Provision OSC Terminations” procedure on page 3-84.
Step 24 Create a loopback on the OPT-BST card by connecting the LINE TX port with LINE RX port using a
patchcord and 10-dB bulk attenuator.
Step 25 Wait 90 seconds, then in node view click the Alarms tab. Verify that the LOS alarms on the OPT-BST
and OSCM cards have cleared. The clearing of the LOS alarms indicates that the OSC link is active for
this side of the shelf.
Note An SDCC Termination Failure alarm will continue to appear due to the OSC signal loopback.
If the alarms clear, continue with Step 26. If not, perform the following steps:
a. Display the OPT-BST card in card view.
b. Click the Provisioning > Optical Line > Optics Thresholds tabs.
c. Under Types, click Alarms, then click Refresh.
d. Locate the Port 2 Power Failure Low parameter. Double-click the table cell and change the value to
–30 dBm.
e. Locate the Port 4 Power Failure Low parameter. Double-click the table cell and change the value to
–40 dBm.
f. Click Apply, and then Ye s .
g. Wait 90 seconds, then in node view click the Alarms tab. Verify that the LOS alarms on the
OPT-BST card has cleared. If so, continue with Step 25. If not, disconnect the OSCM card from the
OPT-BST.
h. Create a loopback on the OSCM card by connecting a patch cable from the OSC TX port to the
OSC RX port using a 10-dB bulk attenuator.
