It is a technique for modulating data that use two frequencies. Frequency

While one particular frequency is used to represent the binary one, another frequency is
used to indicate the binary zero. FSK is used in low speed modems when, in full-duplex
transmission, two different frequencies are used in each direction, resulting in four
different frequencies being used.
Another Caller ID format is DTMF (Dual-Tone Multiple Frequency).
