levels respectively for ALC and ASD to protect the system from overpower. On the Rx path, the default gain is set to put out 20 dBm, which is 7 dB lower than the maximum output power with consideration of traffic fluctuation of the mobile station. If different output level is desired, Rx ATT value of RU can be set manually to change output power level. When output power level is manually changed by adjusting Rx.
