Ad Insertion Test Menu
Ad insertion signals are generated by the unit, but controlled by the uplink programmer. Local
cable companies use ad insertion signals to control and to queue the insertion of commercials in
cable headends. There are two ways to provide ad insertion. One is a dedicated digital DTMF
differential output for cue tones. The other way is to use a dedicated contact closure relay. Use the
Ad Insertion Test menu to turn on and off the cue tones and the relays.
