Signaling Encoder and Decoder - Screens and Control Fields

Control Fields for the Signaling Encoder and Decoder

Standard

This field specifies the standard for the signal being tested.

Decoder Operating Considerations

This setting alters the decoder’s function by specifying the expected frame structure and channel range for the incoming signal.

Trying to run a test with the wrong standard selected will result in incorrect decoded data, or will display an operating error message.

Encoder Operating Considerations

Each standard affects the following conditions:

The types of frames that can be sent.

The range of valid channel numbers.

The encoding of the frame data.

The interpretation of received frames.

Screens Where Field is Present

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

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

Status

This field indicates what the encoder or decoder is doing.

Idle is displayed when no data is being sent.

Control is displayed when control channel data is being output.

Working is displayed when a handshake has been performed and working channel data is being sent.

Screens Where Field is Present

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

Stop

Selecting this field stops the data stream being output when the Send Mode is set to Cont or Burst. After this field is selected, the current repetition of the data stream is finished, and the turn-off code is output.

Screens Where Field is Present

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