Verify that the test set displays 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 display at the source and destination nodes.
Step 10
Clear the performance monitoring (PM) counts for the ports that you tested. See the

Step 13 As needed, complete the
Perform a bit error rate test (BERT) for 12 hours or follow your site requirements for length of time. For
Step 14
information about configuring your test set for BERT, see your test set user guide.
Step 15 After the BERT is complete, print the results or save them to a disk for future reference. For information
about printing or saving test results, see your test set user guide.
Stop. You have completed this procedure.

VC low-order path tunnels allow VC low-order path circuits to pass through intermediary ONS nodes
Note
without consuming VC low-order path matrix resources on the 15310E-CTX-K9 card. VC low-order
path tunnels can carry 28 VC-12 circuits. In general, creating VC low-order path tunnels is a good idea

Test the loopback cable by connecting one end to the test set Tx port and the other end to the test set
Rx port. 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.
Attach the loopback cable to the port you are testing. Connect the test set to the circuit source port.
Connect the Tx port of the test set to the circuit Rx port, and the test set Rx port to the circuit Tx port.
E1—If you are testing an unmultiplexed E1, you must have a DSX-1 panel or use the high-density
E1 interface through the LFH-96 connector. Set the test set for E1. For information about
configuring your test set, consult your test set user guide.
DS-3/E3—If you are testing a clear channel DS-3 or E3, you must have a direct DS-3/E3 interface
into the node through the broadband electrical (BBE) ports on the CTX card. Set the test set for clear
channel DS-3. For information about configuring your test set, consult your test set user guide.
