notes

The first dutch dial tone was a combination of 150 Hz and 450 Hz (at least until up to 1977). The second dial tone was 450 Hz with electromechanical systems and 425 Hz with computer controlled exchanges.

When the second dial tone was abolished on October 10, 1995, no more electromechanical exchanges existed and the frequency of the second dial tone was used for the dial tone.
