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
continuing.
Step 9 Create a physical loopback at the circuit destination:
Attach one end of a patch cable to the destination port Tx connector.
a.
Attach the other end to the port Rx connector.
b.
At the circuit source:
Step 10
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 displays a clean signal. If a clean signal is not displayed, repeat Steps
Step 11
8 to make sure the test set and cabling are configured correctly.
Inject BIT errors from the test set. To verify that you have a complete end-to-end circuit, verify that the
