Signaling Encoder and Decoder - Screens and Control Fields

Control Fields for the Signaling Encoder and Decoder

Stop DSAT (FVC)

This field is available only in NAMP-NTAC mode.

Selecting this field stops the digital supervisory audio tone.

Screens Where Field is Present

SIGNALING ENCODER (Modes: NAMP-NTAC)

Stop Filler (FOCC)

Selecting this field stops the Filler information from being output after Send Filler or Send is used.

Screens Where Field is Present

SIGNALING ENCODER (Modes: AMPS-TACS, NAMP-NTAC)

Stop Meas

This field is used to disarm the decoder when making single measurements (encoder Send Mode is set to Single). It is not used when making continuous (Cont) measurements.

Screens Where Field is Present

SIGNALING DECODER (Modes: All Modes)

Sym

The symbol column corresponds to the DTMF decoder’s symbols assigned for each tone. As each tone pair is analyzed, the corresponding symbol is listed in this column.

Operating Considerations

The symbol assigned to a received tone is based on the closest symbol frequency to that pair.

Screens Where Field is Present

SIGNALING DECODER (Modes: DTMF)

Symbol Frequencies (Hz)

The eight column/row frequencies are automatically entered by the Standard field setting. You can change the frequency values using the DATA keys.

Screens Where Field is Present
