Parameter Descriptions

6. CPA SAT Tone (Hz)

This parameter sets the frequency of the SAT (supervisory audio tone)

that will be used on all analog voice channels. The supervisory audio

tones are out-of-voice-band audio tones used for cell site identification.

One of three frequencies may be assigned: 5970, 6000, and 6030 Hz.

One of the three tones is added to the voice transmission of all call

within an individual cell. The MSUT then detects the tone and

modulates the transmitted voice channel carrier with a constant

(relative) phase tone which is filtered or regenerated from the received

tone to establish a closed loop between the mobile (MSUT) and the cell

site. Transmission of the SAT by a MSUT is suspended during

transmission of wideband data on the reverse voice channel, but is not

suspended when the signaling tone (ST) is sent.

Example

If you want the SAT to be at 6000 Hz, you would enter 6000 as the

value. All values are entered in Hz.
