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 9-8
On
both sides
of the connection, set
Push to Talk mode
to

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
.
