Chapter 5 Turn Up Network
NTP-A174 Linear ADM Network Acceptance Test
• DS3XM-6/DS3XM-12—If you are testing a DS-1 circuit on a DS3XM-6 or DS3XM-12 card you
must have a DSX-3 panel or a direct DS-3 interface to the ONS 15454. Set the test set for a
multiplexed DS-3, then choose the DS-1 to test on the multiplexed DS-3. For information about
configuring your test set, consult your test set user guide.
• OC-N—If you are testing an OC-N circuit, set the test set for the applicable circuit size. For
information about configuring your test set, consult your test set user guide.
Step 8 Verify the integrity of all patch cables that will be used in this test by connecting one end to the test set
Tx connector and the other end to the test set Rx connector. If the test set does not run error-free, check
the cable for damage and check the test set to make sure it is set up correctly before going to the next step.
Step 9 Create a physical loopback at the circuit destination card. To do so, attach one end of a patch cable to
the destination port’s Tx connector; attach the other end to the destination port’s Rx connector.
Step 10 At the circuit source card:
a. Connect the Tx connector of the test set to the circuit Rx connector.
b. Connect the test set Rx connector to the circuit Tx connector.
Step 11 Verify that the test set shows a clean signal. If a clean signal does not appear, repeat Steps 6 through 10
to make sure the test set and cabling are configured correctly.
Step 12 Inject BIT errors from the test set. Verify that the errors appear at the test set, indicating a complete
end-to-end circuit.
Step 13 Complete the “DLP-A356 TCC2/TCC2P Card Active/Standby Switch Test” task on page 20-40.
Step 14 Complete the “DLP-A255 Cross-Connect Card Side Switch Test” task on page 19-37.
Step 15 Complete the “DLP-A88 Optical 1+1 Protection Test” task on page 17-85 to test the OC-N port
protection group switching.
Step 16 Set up and complete a BER test. Use the existing configuration and follow your site requirements for
length of time. Record the test results and configuration.
Step 17 Remove any loopbacks, switches, or test sets from the nodes after all testing is complete.
Step 18 In network view, click the Alarms tab.
a. Verify that the alarm filter is not on. See the “DLP-A227 Disable Alarm Filtering” task on
page 19-17 as necessary.
b. Verify that no unexplained alarms appear on the network. If unexplained alarms appear, resolve
them before continuing. Refer to the Cisco ONS 15454 Troubleshooting Guide if necessary.
Step 19 Delete the test circuit. See the “DLP-A333 Delete Circuits” task on page 20-21.
Step 20 Repeat Steps 6 through 19 for the next linear ADM node you are testing.
Step 21 If a node fails any test, repeat the test while verifying correct setup and configuration. If the test fails
again, refer to the next level of support.
After all tests are successfully completed and no alarms exist in the network, the network is ready for
service application.
Stop. You have completed this procedure.
