Description The total RX gain (from antenna to RUG/RUS/RRUS)
is outside the recommended range. Probably one or
more values for TMA gain or RX cable/feeder loss are
wrongly defined in the IDB.
Action Follow the instructions below until the fault is resolved.
• Confirm with the OMT that the IDB is correct
regarding installed TMAs. If not, then modify and
install a new IDB.
• If applicable, check the defined values for TMA
gain, RX cable/feeder loss and HLout/HLin cable
loss in the IDB.
Note: TMA Loss = 􀀀TMA Gain
• Reset the RUG/RUS/RRUS.
• Reset the DUG.
• For non-TMA configurations, set the feeder loss
value to 0 db.
