Working with Signalling Profiles 131
Action
Specifies the action when the base station detects the specified subtone.
Encode Signal
Specifies the subtone that the base station encodes when it repeats signals with the
subtone specified in the Decode signal column.
Note: If a strong signal is received, the receiver can unmute before
the subaudible signalling is detected. For a short time, the base
station will repeat using the default encode signalling before using
the signalling selected by the Encode Signal column. This occurs for example
if RSSI gating is enabled and the second gating logic box is set to OR (so that
either RSSI or subaudible signalling can unmute the receiver).
Reminder Tone
When the Reminder Tone column is set to ‘Enabled’, the base station includes
a reminder tone in its transmissions. You configure the reminder tone in the
Advanced tab.
Audio Path
By default, the Audio Path column is set to ‘Enabled.’ When it is set to
‘Disabled,’ the audio path is disabled, and the base station transmits carrier (and
a reminder tone if it is configured to do so), but no audio.
Default encode signalling
In the Add or Edit Signalling Profile dialog box, Subaudible Signalling tab, the
Default encode signalling area lets you specify the subtone to be used when
transmitting audio from line in, when repeating received signals without
subaudible signalling, when repeating received signals with subaudible
signalling that has not been decoded.
Option Action
Gate receiver Opens the receiver gate and passes the received audio on. Also sets the system flag
‘Tone
nn detected’ where ‘ nn ’ is the number of the subtone. This flag is a Task
Manager input; any tasks with this input will be executed when the base station
detects the subtone.
Task Manager only Sets the system flag ‘Tone nn detected’ where ‘ nn ’ is the number of the subtone. This
flag is a Task Manager input; any tasks with this input will be executed when the base
station detects the subtone.
In systems that use subaudible signalling, the receiver does not pass the received
audio on (the receiver gate only opens when the receiver decodes a tone configured
to gate the receiver).
In systems that do not use subaudible signalling, the receiver still passes the received
audio on (the receiver gate opens irrespective of the subaudible signalling).
Option Action
Same as received Encodes the transmission with the same subtone that was
in the received signal.
None Gives the transmission no subaudible signalling.
[any CTCSS tone or
DCS code] Encodes the transmission with the subtone you specify
