Test and Delete the Ethernet Hairpin Circuit

Step 1 If the test set is not already sending traffic, send test traffic on the loopback circuit.

Step 2 Examine the test traffic received by the test set. Look for errors or any other signal information that the

test set is capable of indicating.

Step 3 If the test set indicates a good circuit, no further testing is necessary with the hairpin circuit. Clear the

hairpin circuit:

Step 1 Perform a reset on the Active cross-connect card to make the Standby card Active:

a. Determine the standby cross-connect card. On both the physical node and the CTC node view
