12.3 Restricting Transmission to Avoid Interference with Other Communications (Cross-
busy)
The repeater can restrict transmission in order to prevent the transmission from interfering with other communications
if the channel is being used by another transceiver when the repeater transmits using the Repeat PTT control,
Network PTT control, Console PTT control or SIP PTT control.
In order to use this function, an external transceiver that is used to monitor the transmit frequency of the repeater is
required. Also, Repeat Disable needs to be assigned to an AUX Input port of the repeater.
If the BUSY signal is applied from an external transceiver monitoring the transmit frequency of the repeater to the AUX
Input port to which Repeat Disable is assigned, the repeater determines whether to allow the transmission by using
the Repeat PTT control, Network PTT control or Console PTT control.
According to the configuration for Cross-busy, the repeater behaves as below:
Configuration for
Cross-busy
Enabled
Disabled
Also, the behavior varies according to the transmission status of the repeater, the configuration for Cross-busy, and
the status of Repeat Disable/Enable.
If transmission starts by using the Repeat PTT control or Network PTT control while not transmitting:
Configuration for
Cross-busy
Enabled
Disabled
