4.15.2.1 TRC Supported Functionality
Channel – The dispatch console user uses the Select Frequency command to change the
Consolette’s radio channel. This will select items such as a talk group and an air interface type.
The number of channels that can be changed by the dispatcher is 14.
NOTE: Selection of 16 channels is possible if the tone table is set up to not use Coded/Clear
operation.
When a Select Frequency command is received from the Console, the Consolette will send a
message to the mobile radio to steer it to the channel requested. The channel number from the
Console is mapped linearly to a zone and channel in the mobile radio. For example, if each zone
has 5 channels, and the Console requests channel 8, the Consolette will steer the mobile to
channel 3 in zone 2. If the mobile does not allow the indicated channel, the Consolette will
generate a “bonk” tone and remain in the current channel.
NOTE: The Consolette is capable of 1250 channels and these can be accessed from the O5
control head.
Coded/Clear – When a coded or clear (encryption on or off) command is received, the Consolette
will send a message to the mobile radio to set encryption to the indicated state. If the mobile does
not allow the indicated encryption state on the current channel, the Consolette will generate a
“bonk” tone and remain in the prior state.
PTT – To make a voice transmission, first select the desired channel using the Select Frequency
feature. Then the console user also ensures that the correct secure mode (if configured) is
chosen.
NOTE: For encrypted voice calls, the Console sends the request for secure mode to the
Consolette so the Consolette can encrypt the audio. The Console does not encrypt the
audio associated with coded mode calls.
