Subscriber Unit (Call Interrupt)
Call Interrupt is the function to interrupt voice communications from subscriber units other than the calling subscriber
unit by sending and receiving a message requesting Call Interrupt when the repeater repeats transmission.
When a message requesting Call Interrupt is received from a subscriber unit other than the calling subscriber unit, the
repeater stops repeating and sends a message requesting Call Interrupt to the calling subscriber unit.
When the calling subscriber unit receives the message requesting Call Interrupt from the repeater, the calling
subscriber unit sends a call end message to the repeater, and then stops transmission.
The repeater sends a message requesting Call Interrupt for an approximate maximum of 3.6 sec. If a call end
message from the calling subscriber unit cannot be received, the repeater continues to repeat when the calling
subscriber unit continues transmission.
Note
To use this function, Call Interrupt also needs to be enabled on the subscriber units.
・
・ While the repeater sends a message requesting Call Interrupt, audio signals are not repeated.
Because Call Interrupt is a function incompatible with the systems and subscriber units of other companies, the function is
・
unavailable if the subscriber units of other companies are used.
If the configuration of the Intersite Call system is Site 1 and Site 2, the system behaves as follows:
・
Site 1: Subscriber Unit 1, Repeater 1
Site 2: Subscriber Unit 2,
Subscriber Unit 3 ("Interrupt CALL" is configured in Busy Channel Lockout.), Repeater 2 ("Network PTT" has a
higher priority level than "Repeat PTT" in PTT Priority.)
If Subscriber Unit 2 starts voice communication to Subscriber Unit 3 after Subscriber Unit 1 starts voice communication to
Subscriber Unit 3, the voice communication from Subscriber Unit 1 to Subscriber Unit 3 has a higher priority according to the
configuration value for PTT Priority in Repeater 2. Also, if a message requesting Call Interrupt is sent from Subscriber Unit 3 to
Subscriber Unit 1, the repeat behavior from Subscriber Unit 2 to Subscriber Unit 3 starts after the voice communication from
Subscriber Unit 1 is stopped. To interrupt the voice communication from Subscriber Unit 3 to Subscriber Unit 2, Subscriber
Unit 3 needs to resend the message requesting Call Interrupt to Subscriber Unit 2.
Configuration using KPG-D7
