Figure 5-1
“Shoot” Versus “Don’t Shoot”
Figure 5-1 illustrates the following three stages in a trunked channel acquisition delay scenario:
•
A: The audio is being sent into the SIP PBX by radio #1. Radio #1 is conferenced with
radio #2.
•
B: Radio #2 is an 800 MHz trunked radio with a channel acquisition delay of 350
milliseconds. Therefore, radio #2 will not start transmitting the audio from radio #1 until
350 ms have past, and the first word of the message is clipped.
•
C: If the ARA-1 delays the audio to radio #2 by at least as long as the channel acquisition
delay, the entire message gets through.
