NTP- D342 Four-Fiber MS-SPRing Acceptance Test
• For VC3 circuits, complete the “NTP-D54 Create an Automatically Routed Low-Order VC3
Circuit” procedure on page 6-31. When you set the circuit state, choose Unlocked and check the
Apply to drop ports check box.
• For VC12 circuits, complete the “NTP-D81 Create an Automatically Routed Low-Order VC12
Circuit” procedure on page 6-19. When you set the circuit state, choose Unlocked and check the
Apply to drop ports check box.
• For VC11 circuits, complete the “NTP-D334 Create an Automatically Routed Low-Order VC11
Circuit” procedure on page 6-7. When you set the circuit state, choose Unlocked and check the
Apply to drop ports check box.
Step 9 Configure the test set for the test circuit type you created:
• VC4 or VC4-nc—If you are testing a VC4 circuit or a VC4-nc circuit on an STM-N card, you must
have a direct optical interface into the ONS 15454 SDH. Set the test set for STM-N. For information
about configuring your test set, consult your test set user guide.
• 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 10 Verify the integrity of all patch cables that will be used in this test by connecting one end of the cable to
the test set transmit (Tx) connector and the other end of the cable 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 11 Create a physical loopback at the circuit destination card. To do so, attach one end of a patch cable to
the destination port’s transmit (Tx) connector; attach the other end to the port’s receive (Rx) connector.
Step 12 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 13 Verify that the test set shows a clean signal. If a clean signal does not appear, repeat Steps 6 through 12
to make sure the test set and cabling are configured correctly.
Step 14 Inject global BIT errors from the test set. Verify that the errors appear at the test set, verifying a complete
end-to-end circuit.
Step 15 This step will lock out both of the spans on the node where you perform this task. Complete the
“DLP-D254 TCC2/TCC2P Card Active/Standby Switch Test” task on page 19-59.
Step 16 This step will lock out both of the spans on the node where you perform this task. Complete the
“DLP-D255 Cross-Connect Card Side Switch Test” task on page 19-60.
Step 17 Complete the “DLP-D91 MS-SPRing Switch Test” task on page 17-84 to test the MS-SPRing protection
switching at Node 1.
Step 18 Complete the “DLP-D93 Four-Fiber MS-SPRing Span Switching Test” task on page 17-89 at Node 1.
Step 19 Set up and complete a BER test on the test circuit between Node 1 and 2. Use the existing configuration
and follow your site requirements for 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.
