Signaling Encoder and Decoder - Screens and Control Fields

Control Fields for the Signaling Encoder and Decoder

Mode

This field is used to choose which of the Test Set’s Decoder screens to display.

Func Gen

DTMF

AMPS-TACS

NAMP-NTAC

Screens Where Field is Present

SIGNALING DECODER (All Modes)

SIGNALING ENCODER (All Modes)

Num of Bits

This field lists the total number of bits displayed. This number is dependent on Data Rate of the signal being decoded, the Gate Time of the decoder, and the size of the decoder’s data buffer.

Operating Considerations

The buffer has a maximum capacity of:

1584 bits for decoding Reverse Voice Channel (RVC) data streams.

1583 bits for decoding Reverse Control Channel (RECC) data streams.

This measurement is not available for NAMPS-NTACS RVC decoding.

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

Off Time

For the encoder, this field sets the length of time each DTMF tones is off during the sequence.

For the decoder, this measurement column lists the length of time each tone is “off” prior to the next tone being received.
