NTP-A176 Four-Fiber BLSR Acceptance Test
For OC-N circuits, complete the
procedure on page
ports check box.
Configure the test set for the test circuit type you created:
Step 9
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 one end of the cable to
Step 10
the test set Tx connector and the other end of the cable 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.
Create a physical loopback at the circuit destination card. To do so, attach one end of a patch cable to
Step 11
the destination port's Tx connector; attach the other end to the port's Rx connector.
At the circuit source card:
Step 12
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 13
to make sure the test set and cabling are configured correctly.
Inject global BIT errors from the test set. Verify that the errors appear at the test set, verifying a complete

Set up and complete a BER test on the test circuit between Node 1 and 2. Use the existing configuration
Step 19
and follow your site requirements for length of time. Record the test results and configuration.
Complete the
Step 20
Step 21
At Node 2, repeat Steps
the east OC-N trunk (span) card of Node 2, which is Node 3. Work your way around the BLSR creating
test circuits between every two consecutive nodes.
After you test the entire ring, remove any loopbacks and test sets from the nodes.
Step 22
Click the Alarms tab.
Step 23
a.
Verify that the alarm filter is not on. See the
