Trunked Announcement - Motorola APX 8500 Manual

Trunking System Controls

Trunked Announcement

The announcement capability allows you to make announcements to the entire user group, monitor talkgroup
calls, and other announcements.
Announcement calls are handled in two different ways, ruthless and non-ruthless preemption.
The two types are called ruthless and non-ruthless preemption.
•
Ruthless Preemption:
When a ruthless preemption announcement call is initiated, the requesting radio begins transmitting
immediately. All associated talkgroup calls taking place on other channels are immediately halted, and the
radios are steered to the announcement call.
Transmitting radios continue to transmit until the PTT button is released, and unmute for the announcement
call.
•
Non-Ruthless Preemption:
When a non-ruthless preemption announcement is initiated, the initiating unit receives a telephone-type
busy tone, followed by a callback when all associated talkgroup conversations end.
