NTP-A177 Path Protection Acceptance Test
• DS-3—If you are testing a clear channel DS-3, you must have a DSX-3 panel or a direct DS-3
interface into the ONS 15454. Set the test set for clear channel DS-3. For information about
configuring your test set, consult your test set user guide.
• DS3XM-6—If you are testing a DS-1 circuit on a DS3XM-6 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 continuing.
Step 9 Create a physical loopback at the circuit destination card:
a. Attach one end of a patch cable to the destination port’s Tx connector.
b. Attach the other end to the 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 has 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. To verify that you have a complete end-to-end circuit, verify that the
errors appear at the test set.
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 From the View menu, choose Go to Network View.
Step 16 Click one of the two spans leaving the circuit source node.
Step 17 Complete the “DLP-A94 Path Protection Switching Test” task on page 17-95 to test the path protection
protection switching function on this span.
Step 18 In network view, click the other circuit source span and repeat Step 17.
Step 19 Set up and complete a BER test. Use the existing configuration and follow your site requirements for the
length of time. Record the test results and configuration.
Step 20 Complete the “DLP-A333 Delete Circuits” task on page 20-21 for the test circuit.
Step 21 Remove any loopbacks, switches, or test sets from the nodes after all testing is complete.
Step 22 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.
c. Complete the “DLP-A516 Export CTC Data” task on page 22-6 to export the alarm information.
Step 23 Click the Conditions tab.
a. Verify that no unexplained conditions appear on the network. If unexplained conditions appear,
resolve them before continuing. Refer to the Cisco ONS 15454 Troubleshooting Guide if necessary.
