Attach loopback cables to the circuit destination card:
Step 6
Verify the integrity of the loopback cable by looping the test set transmit (Tx) connector to the test
a.
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 going to Step
Attach the loopback cable to the port you are testing. Connect the Tx connector to the Rx connector

of the port.
Attach loopback cables to the circuit source node:

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 Step
Attach the loopback cable to the port you are testing. Connect the test set to the circuit source port.
b.
Connect the Tx port of the test set to the circuit Rx port, and the test set Rx port to the circuit Tx port.
Configure the test set for the ONS 15454 card that is the source of the circuit you are testing:
Step 8
DS-1—If you are testing an unmultiplexed DS-1, 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—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 DS3.
After you choose multiplexed DS-3, choose the DS-1 to test on the multiplexed DS-3. For
information about configuring your test set, consult your test set user guide.
EC-1—If you are testing a DS-1 on an EC1 card, you must have a DSX-3 panel or a direct DS-3
•
interface to the ONS 15454. Set the test set for an STS-1. After you choose STS-1, choose the DS1
to test the STS-1. For information about configuring your test set, consult your test set user guide.
Verify that the test set shows a clean signal. If a clean signal does not appear, repeat Steps
Step 9
to make sure the test set and cabling is configured correctly.
Inject errors from the test set. Verify that the errors appear at the source and destination nodes.
Step 10
Clear the performance monitoring (PM) counts for the ports that you tested. See the
Step 11
Selected PM Counts" task on page 20-35
Complete the
Step 12
circuit ports to the service state they were in at the beginning of the test.
Perform the protection switch test appropriate to the SONET topology:

Step 14 Perform a bit error rate test (BERT) for 12 hours or follow your site requirements for length of time. For
information about configuring your test set for BERT, see your test set user guide.
After the BERT is complete, print the results or save them to a disk for future reference. For information
Step 15
about printing or saving test results, see your test set user guide.
