Verify the integrity of all patch cables that will be used in this test by connecting one end to the test set
Step 8
Tx connector and the other end 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:
Step 9
