Chapter 4 Perform Node Acceptance Tests
NTP-G47 Perform the Line Amplifier Node with OSCM and OSC-CSM Cards Acceptance Test
b. Complete the “NTP-G37 Run Automatic Node Setup” procedure on page 3-83.
c. Create the OSC channels using the “NTP-G38 Provision OSC Terminations” procedure on
page 3-84.
Step 6 Create a loopback on the OSC-CSM card by connecting the LINE TX port to the LINE RX port using a
patchcord and 10-dB bulk attenuator.
Caution Failure to use proper attenuation might damage equipment.
Step 7 Wait 90 seconds, then in node view click the Alarms tab. Verify that the LOS alarm on the OSC-CSM
card has cleared. The clearing of the LOS alarm 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 alarm clears, continue with Step 8. If not, perform the following steps:
a. Remove the 10-dB bulk attenuator on the OSC-CSM LINE TX and LINE RX ports and reconnect
using only the patchcord.
b. In node view, click the Alarms tab. If the LOS alarm on the OSC-CSM card clears, continue with
Step 8. 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 OSC-CSM card clears, continue with
Step 21. If not, replace the OSC-CSM card.
Step 8 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 9.
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 11.
Step 9 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 10 Measure the TXP output power by connecting the TXP DWDM TX port to a test meter. Record the
results for future reference.
Step 11 Connect the tunable laser transmitter or the TXP_MR_2.5G card DWDM TX port to the OPT-BST
LINE RX port using a 10-dB bulk attenuator.
Caution Failure to use proper attenuation might damage equipment.
