NTP- D343 SNCP Acceptance Test
• VC3—If you are testing a clear channel E3/DS3I, you must have a patch panel or a direct E3/DS3I
interface into the ONS 15454 SDH. Set the test set for clear channel E3/DS3I. For information about
configuring your test set, consult your test set user guide.
• VC12—If you are testing an E1, you must have a patch panel or a direct E1 interface to the
ONS 15454 SDH. Set the test set for E1. For information about configuring your test set, consult
your test set user guide.
• VC11—If you are testing a VC11 circuit on an STM-N or MRC-12 card, you must have a direct
optical interface to the ONS 15454 SDH. Set the test set for STM-N. 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
transmit (Tx) connector and the other end to the test set receive (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 transmit (Tx) connector.
b. Attach the other end to the port’s receive (Rx) connector.
Step 10 At the circuit source card:
a. Connect the transmit (Tx) connector of the test set to the circuit receive (Rx) connector.
b. Connect the test set receive (Rx) connector to the circuit transmit (Tx) connector.
Step 11 Verify that the test set shows a clean signal. If a clean signal does not appear, repeat Steps 1 through 6
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-D254 TCC2/TCC2P Card Active/Standby Switch Test” task on page 19-59.
Step 14 Complete the “DLP-D255 Cross-Connect Card Side Switch Test” task on page 19-60.
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 Compete the “DLP-D94 SNCP Protection Switching Test” task on page 17-91 to test the SNCP
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-D27 Delete Circuits” task on page 17-21 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-D227 Disable Alarm Filtering” task on
page 19-25 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 SDH Troubleshooting Guide if necessary.
c. Complete the “DLP-D147 Export CTC Data” task on page 18-38 to export alarm information.
