The fixed tones are generated by the tone generator in the exchange. A maximum of four fixed tones can be generated.

The fixed tones are used by a simplified tone generator on the line board to generate some traffic tones by interrupting the fixed tones. The fixed tones are automatically calculated in the BMS-program by analyzing how these traffic tones are defined.
