Radio ID Decoding
The ISW data received from the radio is de-
coded and displayed on the analyzer. The fol-
lowing data is decoded and displayed for Astro
signaling trunked radios: Talkgroup, Unit, and
Call Type.
Manual Mode
The trunking analyzer supports a mode in
which the operator can exit from the trunking
screens and access standard displays of the
analyzer while the test sequence is in progress.
Radios with Message Trunking
The trunking analyzer supports the testing of
message trunked radios.
Radios with Message Trunking and PTT ID
Enabled
The trunking analyzer supports message
trunked radios testing with PTT-ID enabled.
Transmission Trunked Radios
The trunking analyzer testing of transmission
trunked radios is somewhat limited due to the
nature of the radio. Test sequences can be
performed on transmission trunked radios by
pressing the PTT of the radio and keeping the
radio keyed while switching to other display
screens to make measurements and observe
waveforms. Once the PTT button on the radio
is released, the transmission trunked radio
returns to the control channel and the test must
be re-started in order to rekey the radio.
Dispatch Call
The analyzer supports dispatch call processing
where the radio, or the system, initiates the call
sequence. The dispatch type call is where one
radio is communicating through a repeater
with several other radios assigned to the same
group.
Call Alert
The analyzer supports the testing of call alert
service. The analyzer simulates the signaling
for the radio to initiate, or to receive a call
alert.
Failsoft
The analyzer simulates an inoperative central
controller by not transmitting OSWs on the
control channel, and sending the failsoft word
on the failsoft channel.
