DFSI/AFSI. DFSI will be enabled when the Talkgroup In function is driving a P25 block, and
AFSI will be enabled when driving a PCM/analog block.
To setup Talkgroup In, drag the function block onto the signal map, right click, select
“Edit” and enter a valid port number, corresponding to an appropriate Talkgroup Out RTP
port number, for Unicast, or a valid IP address and port number, for Multicast.
For detailed configuration on EclipseNet consult the Eclipse2 Application Guide.
6.2.26. Multi-Tone Decoder
Provides CTCSS and DCS decoding. The output of this block is audio with the CTCSS/DCS
tones filtered out by a high pass filter, with a 300Hz cut-off frequency. The output is active
only when the corresponding CTCSS/DCS signal is detected at the input.
A standard DCS/CTCSS EIA Tone set is used, with tones in the frequency range 67.0Hz to
254.0Hz. The frequency of the decoder is set by editing the icon on the signal graph.
Instantiate one multi-tone decoder for each frequency to be decoded, setting each instance
to a different frequency. Up to ten different frequencies may be decoded.
A typical configuration connects this block after the FM Demodulator, the output of the
demodulator being connected in a parallel configuration to the input of each decoder. The
output of each decoder may be processed independently, or summed and fed into a
common signal path.
6.2.27. Multi-Tone Encoder
Provides CTCSS and DCS encoding.
This block uses the standard DCS/CTCSS EIA Toneset, with frequencies ranging from 67.0Hz
to 254.0Hz. The frequency of the encoder is set by editing the icon on the signal graph.
Instantiate one multi-tone encoder for each frequency to be encoded, setting each instance
to a different frequency. Up to ten different frequencies may be encoded.
The deviation levels are set via the channel menu: 12.5KHz Channel = 250Hz and 25KHz
Channel = 500Hz. The CTCSS block supports Reverse Tone Burst and a programmable No
Tone Period, at the end of transmission, from 0 to 999ms, set via the channel menu.
A typical configuration connects this block before the FM Modulator. The encoder output
for each frequency should be summed and fed into the modulator. The input of each
encoder may be from an independent signal path, or a single path may be split and
connected to the encoder inputs, in parallel.
