Step 1 Select a node with PXM-T3 back card.

Step 2 Disable the receive FEAC validation criteria by using CLI command, cnfln -ds3<slot>.<port> -rfeac 3.

Step 3 Using dspln -ds3<slot>.<port>, check that the FEAC validation code is disabled and the line is not in loopback.

Step 4 Put the HP cerjac tester in loopback mode by pressing the loopback up button.

Step 5 From the tester, send a pattern and verify that it is not received back on the tester.

Step 6 Check that dsplog does not show any errors or alarms logged.

Pass Criteria:

•Disabling the FEAC validation code put the line in no loop.

•Anything transmitted from the tester is not received back on the tester when FEAC codes are disabled on the DS3 interface.

•No errors logged on the console or the log.

Configure DS3 Loopback Codes from the Standby PXM1 Card

To verify that DS3 loopback codes cannot be configured from the standby PXM-1 card:

Step 1 Select a node with redundant PXM-T3 cards.

Step 2 Log on to the standby card.

Step 3 Configure the line using cnfln -ds3<slot>.<port> -felpbnum 30.

Step 4 Try to configure the transmit FEAC code to be dsx3SendNoCode by using CLI command, cnfln -ds3<slot>.<port> -tfeac 1.

Step 5 Check that CLI rejects the command and fails to accept it.

Step 6 dsplog shows logs an error or a alarm logged.

Step 7 On the tester (for example, HP cerjac tester), check that the code for dsx3SendNoCode has not been received.

Pass Criteria:

•DS3 loopback codes cannot be invoked from the standby card.
