About the behavior of the transceiver when sending an Individual Call
The transceiver behaves as follows depending on the response message from the system after initiating an Individual Call
in a P25 Trunking system:
Table 2-8 Behavior of the Transceiver When Sending an Individual Call
Status
Transceiver Behavior
When a rejection
response message is
received from the
target transceiver
The Call Deny Tone (3 beeps) sounds from the transceiver, and “Call Deny” appears on the display
for 1 sec. Then, the transceiver restores the channel display and the Individual Call ends. If
Incoming Reset Time of the transmitting transceiver elapses and the call ends, the behavior of the
transceiver is also the same.
When no response is
received from the
target transceiver
If the other party does not respond even if the time configured in Initiating Reset Timer expires,
No reply Tone (4 beeps) sounds from the transceiver, and “No reply” appears on the display for
1 sec. Then, the transceiver restores the channel display and the Individual Call ends.
When the transceiver
receives a response
message indicating the
queue state from the
system
The Call Queue Tone (2 beeps) sounds from the transceiver, “Queued” appears on the display,
and the transceiver enters the standby state.
When the transceiver
receives a service
invalid message from
the system
The Call Invalid Tone (4 beeps) sounds from the transceiver, and “System Deny” appears on the
display for 1 sec. Then, the transceiver restores the channel display and the Individual Call ends.
When the transceiver
does not receive any
messages from the
system
The Call Fail Tone (2 beeps) sounds from the transceiver, and “Fail” appears on the display for 1
sec. Then, the transceiver restores the channel display and the Individual Call ends.

Receiving an Individual Call
If the received Individual ID matches the Individual ID configured for the transceiver, the transceiver can receive the Individual Call.
Depending on the configuration in KPG-D1/ D1N and system configuration, the transceiver receives an Individual Call in
the following states:
0
Automatic Response (KPG-D1/ D1N configuration)
If
Automatic Response
is enabled, and when the receiving transceiver receives from the system a message requesting
reception, the transceiver automatically sends an acknowledgment and can initiate an Individual Call.
If
Automatic Response
is disabled, and when the receiving transceiver receives from the system a message requesting
reception, the transceiver can initiate an Individual Call by pressing the
PTT
switch or
Call Response
key to send an
acknowledgment.
0
Availability Check (system configuration)
The transmitting transceiver sends a message requesting an Individual Call to a system when initiating an Individual
Call, and the system sends a message requesting an acknowledgment to the receiving transceiver to confirm the
availability of the receiving transceiver.
The transmitting transceiver sends a message requesting connection to the system, and the system sends a message
for traffic channel assignment if the system allows this request. When the transceiver receives this message, the
transceiver automatically migrates to a traffic channel, and then the transceiver will emit the received audio on a traffic
channel.
