old phone phreak articles from the days of analog phone switching would give you info as well, since people used to build little boxes to generate these tones and others. For example, the touch tones on your consumer phone were not the same as those used by long distance operators to place or redirect calls. One frequency, 2600 HZ, was infamous and useful enough to become the name of the leading hacker magazine for years.

sometimes even four frequencies.
