Push to Talk (PTT)
Overview The push-to-talk feature allows Avaya 3626 Wireless
Telephones to operate in a push-to-talk (PTT) group
broadcast mode in addition to the standard telephone
operation.
PTT is automatically disabled during a PBX call. When the
PBX call is ended, PTT automatically resumes.
The Avaya 3626 Wireless Telephone supports 8 multicast
channels with the current channel saved in memory on the
phone. A PTT call is initiated by pressing the
Talk button
located on the right side of the handset. All Avaya 3626
Wireless Telephones that are monitoring that channel will
hear the transmission.
Selecting a channel See Setting User Preferences below.
The call period The two-way radio operates on the concept of a push-to-talk
session or 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 PTT mode controls the keypad during a push-to-talk
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 (see below).
Initiating a call Press the Talk button and wait two seconds to activate the
channel before talking. The “start transmit” sound will be
played when you may begin talking.
Transmitting Once a call has been initiated, hold the Wireless Telephone
two inches from your mouth and talk into the microphone.
When the
Talk button is released, the “end transmit” sound
is played. The Avaya 3626 Wireless Telephone then enters
the waiting state where it monitors the channel for up to 10
seconds.
Initiate subsequent transmissions by pressing the
Talk
button on any Avaya 3626 Wireless Telephone using the
same channel. The “start transmit” sound is played
immediately and the user can start talking. 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 Avaya 3626 Wireless Telephone plays the “end
call” sound and reverts to the idle state.
