Chapter 4 Perform Node Acceptance Tests
DLP-G312 Verify the West ROADM Add/Drop Channels
Step 3 Wait 90 seconds, then click the Alarms tab. Verify that the LOS alarms on the west OSCM or OSC-CSM
card and the OPT-BST card have cleared. The clearing of the LOS alarms indicates that the OSC link is
active on the west side.
Note An SDCC Termination Failure alarm will continue to appear due to the OSC signal loopback.
Step 4 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 5.
a. Set the output power to a nominal value, such as –3 dBm.
b. Set the tuner to the wavelength you are testing, then continue with Step 7.
Step 5 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, if needed.
Step 6 If you are using a TXP_MR_2.5G card, connect the TX port to a power meter and record the output
power.
Step 7 Connect the tunable laser transmitter or the TXP_MR_2.5G card DWDM TX port to the west side fiber
patch panel MUX port that corresponds to the west 32WSS card port carrying the tested wavelength.
Step 8 Connect the TXP_MR_2.5G DWDM RX port to the west side fiber patch panel DMX port that
corresponds to the west 32DMX card port carrying the tested wavelength.
Step 9 Display the west 32WSS in card view.
Step 10 Click the Maintenance tab.
Step 11 For each wavelength that you will test, click the table cell under Operating Mode and choose Add Drop
from the drop-down list.
Step 12 Click Apply, then click Ye s to confirm.
Step 13 Click the Provisioning > Optical Chn Optical Connector [n] > Parameters tabs, where n = the
connector number containing the wavelength you are testing. Refer to Table 4-2 on page 4-9, if needed.
Step 14 Scroll to the right until you see the Power Add parameter. Verify that the Power Add value for the tested
port is equal to the output power level of the tunable laser or TXP_MR_2.5G card (measured in Step 6),
+/– 1 dBm.
Step 15 Display the west 32DMX card in card view.
Step 16 Click the Provisioning > Optical Chn > Parameters tab. Record the value under the Power parameter
for the wavelength under test.
Step 17 Verify that the power value from Step 16 reaches the WestSide.Rx.Power.Add&Drop - Drop Power
setpoint, +/– 2 dBm. To view this setpoint:
a. Go to node view and click the Provisioning > WDM-ANS > Provisioning tabs.
b. In the Selector window on the left, expand the West Side parameters tree view.
c. Expand the RX category.
d. Expand the Power category, then highlight Add&Drop - Drop Power.
e. View the WestSide.Rx.Power.Add&Drop parameter on the right side of the pane.
If the power values do not match (+/– 2 dBm), remove, clean, and replace each cable on the west side
of the shelf. See the “NTP-G115 Clean Fiber Connectors” procedure on page 13-25.
Step 18 Display the TXP_MR_2.5G in card view.
