WLAN Handsets 2210/2211 configuration Page 111 of 206
WLAN IP Telephony Installation and Configuration
A PTT call is initiated by pressing the Talk button located on the right side of
the handset. All WLAN Handset 2211s that are monitoring that channel will
hear the transmission.
The two-way radio mode operates on the concept of a PTT session or call
period. The PTT call period begins with the first transmission and ends when
there has been no two-way radio traffic on the channel for 10 seconds. The
PTT mode controls the keypad during a PTT call period. Therefore, it is not
possible to use the keypad for any other function such as accessing the on-
hook menus or accessing an OAI application. However, it is possible to place
a PBX call.
PTT operation
Follow the steps in Procedure 14 to use the PTT feature.
Procedure 14
Initiating a PTT call
1 To initiate a PTT call, press and hold the Talk button. Wait two seconds
to activate the channel before talking.
2 Speak after the “start transmit” sound is heard.
When the Talk button is released, the “end transmit” sound is heard. The
wireless handset then enters the waiting state where it monitors the
channel for up to 10 seconds.
3 Initiate subsequent transmissions by pressing the Talk button on any
WLAN Handset 2211 using the same channel. The “start transmit” sound
is played immediately and speech can begin. The display screen shows
the current active channel. Since all phones on that channel are already
in the receive state, there is no two-second delay.
If no transmission occurs during the 10-second countdown period, the
wireless handset plays the “end call” sound and reverts to the idle state.
