They used to use DTMF codes for remote switching to allow local
inserts or commercials. but I've been out of the CATV business since
1986 when I used to cue up a commercial on 3/4" U-matic tapes and hand
switch the commercials into the system. We sold commercials on three
channels. MTV was the worst. Their signal was that they used a
multiplexed stereo audio channel on the C-band receiver and they turned
off the pilot carrier to control the switch so you had to buy the
controller from them. I just waited for their fade to black and
switched it then.
