Ad Insertion Test Menu
The Ad Insertion Test menu allows the user to test the cue tones and turn the relays
on and off. Ad insertion signals are generated by the DSR-4530, 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:
• A dedicated digital DTMF differential output for cue tones.
• A dedicated contact closure relay.
Press the
56
buttons until the Ad Insertion Test menu appears (shown below).
Caution: Output to the customers may be interrupted. When turned on, the ad
insertion signals can be sent to the local headend equipment.
