Ntp- A175 Two-Fiber Blsr Acceptance Test - Cisco ONS 15454 Series Procedure Manual

NTP-A175 Two-Fiber BLSR Acceptance Test
Configure the test set for the test circuit type you created:
Step 8
DS-1—If you are testing a DS-1 that is not multiplexed, you must have a DSX-1 panel or a direct
•
DS-1 interface into the ONS 15454. Set the test set for DS-1. For information about configuring
your test set, consult your test set user guide.
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/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.
Verify the integrity of all patch cables that will be used in this test by connecting the test set Tx connector
Step 9
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.
Create a physical loopback at the circuit destination card. To do so, attach one end of a patch cable to
Step 10
the destination port's Tx connector; attach the other end to the port's Rx connector.
At the circuit source card:
Step 11
Connect the Tx connector of the test set to the circuit Rx connector.
a.
Connect the test set Rx connector to the circuit Tx connector.
b.
Verify that the test set shows a clean signal. If a clean signal does not appear, repeat Steps
Step 12
to make sure the test set and cabling are configured correctly.
Step 13 Inject BIT errors from the test set. Verify that the errors appear at the test set, verifying a complete
end-to-end circuit.
Complete the

Although a service interruption under 60 ms may occur, the test circuit should continue to work before,
during, and after the switches. If the circuit stops working, do not continue. Contact your next level of
support.
Step 16 Complete the
Step 17 Set up and complete a BER test on the test circuit. Use the existing configuration and follow your site
requirements for length of time. Record the test results and configuration.

node and span in the ring. Create test circuits between every two consecutive nodes.
After you test the entire ring, remove any loopbacks and test sets from the nodes.
Step 20
If a node fails any test, repeat the test while verifying correct setup and configuration. If the test fails
Step 21
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. Continue with
Stop. You have completed this procedure.
