Chapter 4 Perform Node Acceptance Tests
NTP-G41 Perform the Terminal or Hub Node with 32MUX-O and 32DMX-O Cards Acceptance Test
Step 5 Create a physical loopback on the west (or terminal) OPT-BST amplifier by using a patchcord with
10-dB bulk attenuators to connect the LINE TX port to the LINE RX port.
Note An SDCC Termination Failure alarm will appear due to the OSC signal loopback.
Step 6 Verify that the OSC link becomes active on the west OSCM or OSC-CSM card. (The OSC termination
must already be provisioned. If not, complete the “NTP-G38 Provision OSC Terminations” procedure
on page 3-84.)
Step 7 Set the tunable laser or the TXP_MR_2.5G card to the first wavelength (1530.33 nm) of the 100-GHz
ITU-T grid. Refer to the tunable laser manufacturer’s documentation or the “DLP-G268 Provision
TXP_MR_2.5G Cards for Acceptance Testing” task on page 4-4.
Step 8 Connect the tunable laser transmitter or TXP_MR_2.5G card DWDM TX port to the CHAN RX 01 port
on the west (or terminal) 32MUX-O card using the available patch panel.
Step 9 Display the west (or terminal) 32MUX-O card in card view.
Step 10 Click the Provisioning > Optical Chn > Parameters tabs.
Step 11 Change the Port 1 Admin State to OOS,MT (ANSI) or Locked,maintenance (ETSI).
Step 12 Verify that the Port 1 power level reaches the provisioned VOA Power Ref setpoint.
Note The tunable laser minimum output optical power (Pout) must be 6 dBm. If the output power is
lower than the specified value, the 32MUX-O card might not reach the provisioned setpoint.
Step 13 If an OPT-BST card is installed, complete the “DLP-G79 Verify the OPT-BST Amplifier Laser and
Power” task on page 4-40 on the west (or terminal) OPT-BST to ensure that the amplifier is working
properly.
Step 14 Complete the “DLP-G80 Verify the OPT-PRE Amplifier Laser and Power” task on page 4-41 on the
west (or terminal) OPT-PRE to ensure that the amplifier is working properly.
Step 15 Restore the default IS,AINS (ANSI) or Unlocked,automaticInService (ETSI) administrative state to the
32MUX-O port that was changed to OOS,MT (ANSI) or Locked,maintenance (ETSI) in Step 11.
Step 16 Repeat Steps 7 through 15 for the remaining 32 wavelengths of the 100-Ghz grid to verify the correct
behavior of all variable optical attenuators (VOAs) inside the 32MUX-O card.
Step 17 Remove the loopback created in Step 5.
Step 18 If the node is a hub node, repeat Steps 5 through 17 for the east side cards.
Step 19 Complete the “NTP-G37 Run Automatic Node Setup” procedure on page 3-83 to restore the original
configuration.
Step 20 Click the Alarms tab.
a. Verify that the alarm filter is not on. See the “DLP-G128 Disable Alarm Filtering” task on page 8-28
as necessary.
b. Verify that no equipment (EQPT) alarms appear indicating equipment failure or other hardware
problems. If equipment failure alarms appear, investigate and resolve them before continuing. Refer
to the Cisco ONS 15454 Troubleshooting Guide or the Cisco ONS 15454 SDH Troubleshooting
Guide for procedures.
Stop. You have completed this procedure.
