Push-to-Talk
Push-to-Talk is available on the WLAN Handset 2211 only.
Push-to-Talk mode enables WLAN Handsets 2211 to operate in a group
broadcast mode in addition to the standard handset operation. The WLAN
Handset 2211 supports eight multicast channels with the current channel
saved in the handset memory.
The Call Period
Push-to-Talk mode operates on the concept of a call period. The Push-to-Talk
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 Push-to-Talk mode controls the handset keypad during the call period.
Therefore, it is not possible to use the keypad for any other functions.
However, it is possible to place and receive telephone calls.

Receive a Push-to-Talk transmission
Upon receiving a Push-to-
Talk transmission, the ―receiving alert‖ tone sounds
and the WLAN Handset 2211 enters the receive state.
In this state, the handset receives all conversations on the selected channel.
The display shows the current active channel, the caller ID of the current
transmitter, and an indication that the handset is receiving a broadcast
transmission.
At the end of a transmission, the handset enters the waiting state, where it
monitors the channel for
up to 10 seconds and displays ―Waiting‖ on the
screen. If no other transmission occurs within 10
seconds, the ―end call‖ tone
sounds and the handset becomes idle.
