Broadband Electrical ports (BBE) DS3/E3—On the ONS 15310-MA SDH, if you are testing a clear
•
channel DS3/ E3, use the BNC connectors on the BICs on the rear of the chassis. Set the test set for
clear channel DS3/E3. For information about configuring your test set, consult your test set user
guide.
STM-M—If you are testing an STM-M 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 to the test set
Step 8
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
going to
Step 9 Create a physical loopback at the circuit destination. To do so, attach one end of a patch cable to the
destination port Tx connector; attach the other end to the port Rx connector.
Step 10 At the circuit source:
a. Connect the Tx connector of the test set to the Rx connector on the circuit source port.
b. Connect the test set Rx connector to the circuit Tx connector on the circuit source port.
Verify that the test set displays a clean signal. If a clean signal is not present, repeat Steps
Step 11
sure the test set and cabling are configured correctly.
Step 12 If a node fails any test, repeat the test while verifying correct setup and configuration. If the test fails
again, refer to the next level of support.
Step 13 Inject BIT errors from the test set. Verify that the errors display at the test set, indicating a complete
end-to-end circuit.
Complete the

Step 15 Set up and complete a BER test. Use the existing configuration and follow your site requirements for the
specified length of time. Record the test results and configuration.
Remove any loopbacks, switches, or test sets from the nodes after all testing is complete. Refer to the

Delete the test circuit. See the
Step 21
After all tests are successfully completed and no alarms exist in the network, the network is ready for
service application.
