The coupler loss is recorded on the coupler using a similar label and the

internal loss for the LCU is recorded on a Label on the LCU.

The path loss entered using the hand held terminal is the loss occurring in

the transmitted signal from the LCU before reaching the CT LNA.

Therefore path loss for signals to all shelves is the same.

The path loss for both modem shelves 1&2 and 3&4 = Loss coupler

(LNA) + loss Cable + internal loss of LCU.
