Description: This TC enumerates the alarms for RF interface. txFrequency - Transmitter frequency synthesizer loop is unlocked. rxFrequency - Receiver frequency synthesizer loop is unlocked. rfOutputLevel - Major degradation of transmitter output power is detected. rxAfc - The frequency of the received signal is outside the range of the Automatic Frequency Control in the RAU receiver. rfInputLevel - Receiver RF input signal level has dropped below the threshold for the receiver. rfInputThreshold - The RF input level has dropped below the xfRFInputAlarmThreshold. rfOutputLevelATPC - The transmitter output power has been continuously at 'Patpc,max' for too long. This can occur due to several reasons: * The operator has set 'Patpc,max' too low. * The hop attenuation has increased (steady-state). * The transmitter PA is v. * The LNA in Rx is deteriorating.
