Configure the Push to Talk mode parameter according to the requirements of your
application scenario:
-
Scenario 1: Where a control station communicates with a remote mobile
location (see
“Push-To-Talk Application: Scenario 1” on
):
On the button side of the connection, set Push to Talk mode to PTT
CONTROL.
This is required for the air traffic controller (Unit 2) in Scenario 1 (see
).
On the mobile unit side, set the Push to Talk mode to PTT ANSWER.
This is the default value.
-
Scenario 2: Where there are two remote locations (see
To-Talk Application: Scenario 2” on page 9-7
):
On both sides of the connection, set Push to Talk mode to PTT CON-
TROL.
TIP:
As a general rule of thumb in any PTT application, if the PTT device has a
control button, you can set the corresponding E&M/PTT channel to PTT
CONTROL.

Change the other channel parameters from their default values, if desired.
