1.14 Terminating Voice Communications by a Transceiver Other Than the Transmitting Transceiver (Call Interruption)
1.14 Terminating Voice Communications by a Transceiver Other
Than the Transmitting Transceiver (Call Interruption)
Call Interruption is the function to enable a transceiver other than the transmitting transceiver to terminate voice
communications by sending and receiving the Call Interruption request message. A transceiver receiving the Call Interruption
request message on the channel where the transceiver is performing voice communication terminates voice communication.
By pressing the Call Interruption key, a Call Interruption request message can be sent.
Also, a Call Interruption request message can be sent by the following functions:
0
In-call Busy Channel Lockout (Interrupt CALL)
The current incoming call can be interrupted by pressing the PTT switch to respond (Talkback) while receiving an
Individual Call or Group Call addressed to the own transceiver on the channel where "Interrupt CALL" is configured for
In-call Busy Channel Lockout.
0
Interrupt ALL CALL
Call Interruption is executed and voice communication can be terminated when an All Call is initiated during voice
communication (including voice communication not addressed to the own transceiver) on the selected channel.
0
Interrupt Message CALL
Call Interruption is executed and voice communication can be terminated when transmission of a message is initiated
during voice communication (including voice communication not addressed to the own station) on the selected channel.
0
Interrupt Emergency CALL
When the transceiver enters Emergency Mode, Call Interruption is executed and voice communication can be
terminated if voice communication (including voice communication not addressed to the own station) is performed on
the channel used for Emergency Mode.
To send a Call Interruption request message using these functions, Encode (Call Interruption) of the channel used needs
to be enabled. To receive a Call Interruption request message, Decode (Call Interruption) of the channel used also needs
to be enabled.
Note
In DMR Direct Mode, Call Interruption does not function if the received Color Code does not match the Color Code
0
configured in the transceiver, or if the slot number does not match. (Refer to
(Talk Around/ DMR Direct
In Repeater Mode, Call Interruption does not function if the received Color Code does not match the Color Code configured
0
in the transceiver. (Refer to
When a signal encrypted in the AES/ DES, DES (Built-in DES) or Enhanced Encryption format is received, Call Interruption
0
is not activated regardless of the matching status of Color Code and slot number. When a signal that is encrypted by
means of bit scrambling, Call Interruption is activated according to the matching or non-matching status of Color Code
and slot number. (Refer to
A Call Interruption request message can also be transmitted by receiving a PC command from the communication port.
0
To use a PC command, "Data" or "Data + GPS Data Output" needs to be assigned to the communication port of the
transceiver. (Refer to Common FUNC
