Connect a cable from the DS3 test set transmit connection to the IN jack of the DSX-3

associated with the first DS3 or TMUX tributary of the Alcatel-Lucent 1665 DMX

Function unit slot to be tested.

Connect a cable from the DS3 test set receive connection to the OUT jack of the DSX-3

associated with the first DS3 or TMUX tributary of the Alcatel-Lucent 1665 DMX

Function unit slot to be tested.

Result:

verify that the port on the DS3 or TMUX pack is receiving the signal, verify that the

port has transitioned to an "in service" state with the View -> Equipment command.

A port state of "IS" indicates that the pack is receiving a good signal to the port.

While observing the error-free transmission at the DSX, grasp the DS3 cable about two

inches from the BNC connector head and gently rotate (twist) the cable in a clockwise and

counter clockwise direction about 45 degrees (gently).

Result:

connector must be cut off and replaced.

If an error-free signal is not received:
