9.18 Transceiver Behavior in the Case that the System Fails to
Provide the Trunking Control Service (Failsoft)
Failsoft is a function that provides the minimal communication capability for the transceivers in the site coverage area in
the case that the system fails to provide the Trunking control service among the sites, for instance, in a case when a cable
connecting repeaters is cut or an error occurs in communication between controllers.
If the system fails to provide the trunking control service for the site, the system migrates the channel to the Failsoft
channel and then the system will send a broadcast message to the transceivers indicating that the system is in Failsoft
state. When a transceiver searches using the hunt sequence for a channel configured as a Failsoft Channel and then
receives the broadcast message from the system indicating the Failsoft state of the system, the transceiver will enter
Failsoft Mode.
On the Failsoft Channel, signals are simply repeated within the site and only Group voice communications (Conference
Group Call, Broadcast Group Call, All Group Call) can be done for the selected Group ID. While the transceiver searches
for a control channel in adjacent sites at intervals configured for Search Interval Time, and then acquires a channel
operating as a control channel, the transceiver will exit Failsoft Mode.
Transceiver Behavior
1
The transceiver receives the broadcast message from the system indicating the Failsoft state of the
system.
The transceiver enters Failsoft Mode. "FAILSOFT" appears on
the transceiver main display at 1-sec intervals. The LED lights
green while the transceiver is in Failsoft Mode.
