Chapter 4 Perform Node Acceptance Tests
NTP-G46 Perform the Line Amplifier Node with OSC-CSM Cards Acceptance Test
b. Wait 90 seconds then, in node view, click the Alarms tab. If the LOS alarm on the east OSC-CSM
card clears, continue with Step 21. If not, continue with Step c.
c. Display the OSC-CSM card in card view.
d. Click the Provisioning > Optical Line > Optics Thresholds tabs.
e. Under Types, click Alarm, then click Refresh.
f. Locate the Port 3 Power Failure Low parameter. Double-click the table cell and change the value to
–30 dBm.
g. Locate the Port 6 Power Failure Low parameter. Double-click the table cell and change the value to
–40 dBm.
h. Click Apply, and then Ye s .
i. In node view, click the Alarms tab. If the LOS alarm on the east OSC-CSM card clears, continue
with Step 21. If not, replace the OSC-CSM card.
Step 21 If you are using a tunable laser, follow the manufacturer’s instructions to complete the following steps.
If you are using a TXP_MR_2.5G card, continue with Step 22.
a. Set the output power to a nominal value, such as –3 dBm.
b. Set the tuner to the wavelength under test, then continue with Step 23.
Step 22 If you are using a TXP_MR_2.5G card, complete the “DLP-G268 Provision TXP_MR_2.5G Cards for
Acceptance Testing” task on page 4-4 for the TXP containing the wavelength you will test. Refer to
Table 4-1 on page 4-4, if needed.
Step 23 Connect the tunable laser transmitter or the TXP_MR_2.5G card DWDM TX port to the west OSC-CSM
LINE RX port using a 10-dB bulk attenuator.
Caution Failure to use proper attenuation might damage equipment.
Step 24 If an OPT-PRE card is installed on the west side, complete the “DLP-G80 Verify the OPT-PRE
Amplifier Laser and Power” task on page 4-41. If not, continue with Step 25.
Step 25 Display the east OSC-CSM card in card view.
Step 26 Click the Provisioning > Optical Line > Parameters tabs. 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 27 If an OPT-PRE is installed on the east side of the shelf, complete the “DLP-G80 Verify the OPT-PRE
Amplifier Laser and Power” task on page 4-41 for the east OPT-PRE amplifier. If not, continue with
Step 28.
Step 28 Display the west OSC-CSM card in card view.
Step 29 Click the Provisioning > Optical Line > Parameters tabs and locate the Power value for Port 2. 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 30 Disconnect the TXP or tunable laser from the west OSC-CSM card.
Step 31 Remove the loopback created on the east OSC-CSM card in Step 6.
Step 32 Delete both OSC channels. See the “DLP-G186 Delete an OSC Termination” task on page 10-41.
