Chapter 4 Perform Node Acceptance Tests
NTP-G46 Perform the Line Amplifier Node with OSC-CSM Cards Acceptance Test
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 10.
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 Connect the tunable laser transmitter or the TXP_MR_2.5G card DWDM TX port to the east OSC-CSM
LINE RX port using a 10-dB bulk attenuator.
Caution Failure to use proper attenuation might damage equipment.
Step 11 If an OPT-PRE card is installed on the east side, complete the “DLP-G80 Verify the OPT-PRE Amplifier
Laser and Power” task on page 4-41. If not, continue with Step 12.
Step 12 Display the west OSC-CSM card in card view.
Step 13 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 14 If an OPT-PRE is installed on the west side of the shelf, 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 east OSC-CSM card in card view.
Step 16 Click the Provisioning > Optical Line > Parameters tabs. Locate the Port 2 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 Disconnect the TXP or tunable laser from the east OSC-CSM card.
Step 18 Remove the physical loopback created on the west OSC-CSM card in Step 6.
Step 19 Create a loopback on the east OSC-CSM by connecting the LINE TX port with LINE RX port using a
patchcord and 10-dB bulk attenuator.
Caution Failure to use proper attenuation might damage equipment.
Step 20 Wait 90 seconds, then in node view click the Alarms tab. Verify that the LOS alarm on the east
OSC-CSM card has cleared. The clearing of the LOS alarm indicates that the OSC link is active on the
east side.
Note An SDCC Termination Failure alarm will continue to appear due to the OSC signal loopback,
and an LOS alarm will appear for the west OSC-CSM, Port 1 (OSC).
If the alarm clears, continue with Step 21. 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.
