Does anyone know the name of the Key in tone on the Motorola P25 Series?

I was listening to police transmissions and something that I haven't noticed since now was the "Rodger tone" or the "key in tone" It sounds like a triple beep.

it could be an ani code, used by the dispatcher to see who is calling, then the tones heard could be any combination of 3 tones, There are at least 5900 possible tones you could hear.
