Transmission using the In-call Busy Channel Lockout (Interrupt CALL) function
The In-call Busy Channel Lockout (Interrupt CALL) function can be used to send a Call Interruption request message
before a voice call starts to end voice communication. “Interrupt CALL” needs to be configured in In-call Busy Channel
Lockout
of the channel in use. (Refer to Avoiding Interference with Other Communications (Busy Channel Lockout
(DMR)).)
1
Press the PTT switch during voice communication to respond (Talkback).
“Interrupt” appears on the display, and a Call Interruption request message
is sent to all IDs.
Note
When the PTT
switch is pressed and a response (Talkback) is sent while
receiving a signal encrypted in the AES/ DES, DES (Built-in DES) or
Enhanced Encryption format, Call Fail Tone (2 beeps) is emitted from
the transceiver and “Fail” appears on the display for 1 second. A Call
Interruption request message is not sent in this case.
The same applies during transmission via an Interrupt Emergency Call
and Interrupt ALL Call. However, “Fail” does not appear on the display
for Interrupt Emergency Call and Interrupt ALL Call.
2
Transmission of Call Interruption request message is complete.
When there is no more signal, “Complete” appears on the display for 1
second and voice communication ends.
If the PTT
switch remains depressed, this will be followed by an outgoing
call.
When Individual Call Acknowledge Request is enabled, “Calling”
appears on the display when there is no more signal, and a request
message for confirmation of receipt is sent. (Refer to Initiating an Individual
Call After Ensuring That the Target Party Is Available for Communications
(Individual Call Acknowledge Request).)
Note
If the signal persists even after transmission of the Call Interruption
request message is complete, Call Fail Tone (2 beeps) is emitted from
the transceiver and “Fail” appears on the display for 1 second.
