Signaling Encoder and Decoder - Screens and Control Fields

Control Fields for the Signaling Encoder and Decoder

 

Examples of Input Level Settings

Example 8-1

Example 1

 

Peak deviation 3 kHz, De-emphasis off. Set the input level to 3 kHz.

Example 8-2

Example 2

 

Peak deviation 3 kHz, De-emphasis 750 ms. Set the input level to 3 ⋅

 

0.212 = 636 Hz

Screens Where Field is Present

 

SIGNALING DECODER (All Modes)

Lo Tone

This measurement field lists the frequency or frequency error for the low frequency tone in each tone pair. The measurement type is selected by selecting the Freq field to display a list of measurement choices.

Operating Considerations

Frequency error is calculated by comparing the DTMF Encoder’s frequency settings for each tone pair with the decoded frequencies.

Screens Where Field is Present

SIGNALING DECODER (Modes: DTMF)

Measure

This field is only displayed when the Channel field is set to Voice. This field selects the type of decoded data to display: DSAT or DST codes, message data (Data), or DTMF (Dual-Tone Multi-Frequency) tone data.
