TX saturation means that the TXU delivers maximum RF power
to the PAU but it is still not sufficient to get the desired power
from the PAU. The fault I2A:13 on TRXC is raised at the same
time. Other faults such as I1B:2 and I1B:13 on TX might raise as
Many possible reasons both SW and HW related. Can even be temperature related. Try to block/deblock the TRU. If this doesn’t help, power off/on the TRU or replace the TRU.
