To differentiate radio coverage, the Railway radio stations recognize three call tones (1520, 1750 and
2135 Hz). The DSS1 module can detect and evaluate these sine frequencies. The Radio AF is therefore
switched permanently in idle mode to the fixed AF channel specified under Audio channel - Radio AF.
