RUSS Automated tone

["Russ Butler" <oldradio@earthlink.net>]

I'd appreciate some helpful, techie information, please.  What is the
inaudible tone that is used to cue events in an automated radio station's
programming computer?  And how is that signal generated onto a CD program so
that the radio station can download the digital audio successfully with the
cues to activate commercials, promos, ID's, jingles, etc.?  Do all radio
station's automated systems accept the same tone cue, and where could I
obtain the equipment (or this service) in the Boston area?  Thanks for your
reply and any sources to follow up with.
