TMA-CM
The Tower Mounted Amplifier-Control Module (TMA-CM) is used to provide
a ddTMA with 15 V DC power through the bias injectors. It also identifies
ddTMA faults and forwards this information to the alarm module in the RBS. If
a TMA-CM is used, then it is located in the DXU/dTRU subrack. If a second
TMA-CM is used, then it is located in the 5 TE (x 5.08 mm) OXU position.
