SUMMARY:
The protection line is removed by removing the LSU and LIU-P and
setting the ADU protection line option (mini switch position 1 on S1 or S2) for no
protection. An LFU may be required if interfacing with a DDM-1000 or DDM-2000
multiplexer. The protection line is added by setting the ADU for the protection line
(mini switch position 1 on S1 or S2), optioning and installing the LSU and LIU-P LIU.
When changing the protection line equipage, both the RT and the CO equipment
must be changed.
