DESCRIPTION

The model 3000R-103A Dual Tone Sender is a preprogrammed CATV Cue Tone generator
designed to place DTMF (Touch-Tone*) cues on CATV program audio. The cue tones are
transmitted to provide CATV systems with unattended switching and can signal beginning and
ending of:

- Daily Programming

- Program Segments

- Local Announcements or Commercials
The model 3000R-103A can provide up to eight Cue Tone codes; four ON and four OFF.
Internal Cue Tone Decoders monitor program audio and provide verification that the cues have

been properly transmitted.
Front panel pushbutton switches and indicators permit operation; rear panel terminals allow

external switches and indicators to be added if desired.

*Touch-Tone is a registered trademark of AT&T

INSTALLATION

Three terminal strips are provided on the rear panel of the model R103A for external
connections.

PROGRAM AUDIO CONNECTION:

Cue Tones can be inserted on the same carrier as the program audio or inserted on their own
carrier. If they are to be inserted on the program audio carrier, it is necessary to ensure that no
program audio is present while cue tones are being transmitted. Therefore, the program audio
should be routed through the normally closed contacts of the 3000R-103A’s balanced audio
relay.

A. Open the program audio line and connect the audio source across TBI, terminals 11 and 12.
B. Take the audio output from TB2, terminals 11 and 12.

NOTE: In the event of power or equipment failure the 3000R-103A will not interrupt the program
audio.

If the Cue Tones will be inserted on their own audio carrier, make the connection in step B
above.

MONITOR AUDIO CONNECTION:

Program monitor audio must be wired to TB3, terminals 11 and 12 to provide verification that the
cue tones have been properly transmitted. To accomplish this, jumper TB2 terminals 11 and 12
to TB3 terminals 11 and 12.

If program monitor audio is not available, TB3 terminals 11 and 12 may be wired directly to the
program audio source if desired. The monitor audio input is transformer coupled (600 ohms) to
the internal decoders.

REMOTE SWITCH CONNECTIONS:

Barrier strip TB1, terminals 1 through 9 provide connections for installation of remote switches to
activate cue tone codes.

Momentary pushbutton switches can be wired from any or all terminals 1 through 8, to terminal

9. Momentarily grounding any terminal 1 through 8 will cause the 3000R-103A to transmit the
code controlled by that input.

OPERATION

When the Model R103A is first plugged into a 117 VAC outlet the front panel red indicator lamps
will be “ON” for each channel that is installed.

Pressing the front panel ON switch for any active channel will cause the R103A to send its
preprogrammed Cue Tone out on TB2, terminals 11 and 12. When equipped with 3223B-2
transmission begins when switch is pushed.
