Call Back Priority Interrupt Application
Configuration Requirements:
1. The interrupting subscriber, Subscriber B, must enable Priority Interrupt Encode
on the current channel and set TX Admit to Always Allow.
2. Subscriber A, the interrupted subscriber, must have the enabled Priority
Interrupt Decode option on the current channel.
3. Both the subscribers are on the same channel, using Pseudo Trunk and
meeting the requirements on TX Admit settings.
See Figure 2.8.2-3 for the example.
Figure 2.8.2-3: Call Back Priority Interrupt Application
1. Subscriber A is transmitting voice signals in communication with B and C in
Group Call 1.
2. Subscriber B can call back via PTT key. In the entire process, B will not be
prompted whether the interrupt succeeds.
3. After receiving and decoding the Priority Interrupt command, Subscriber A will
be interrupted and prompted “Call Interrupted” on its main interface. And then it
will receive Group Call 1 from B.
4. Subscriber C will be prompted that the call is over and get Group Call 1 from B.
