Extension
Displays the extension currently assigned to the WT. This
number is for display purposes only; entering it does not assign
the extension in the host telephone system.
Push-to-talk (PTT)
The 3626 WT incorporates push-to-talk functionality. PTT may
be allowed or disallowed in the Admin menu. If allowed, the
user may enable or disable locally, and may set the channel, tone
volume and audio volume. The menu for push-to-talk does not
appear if PTT is disallowed on the Admin menu or if no channel
is enabled on the Admin menu.
Channel The current channel is displayed. The user may enable any PTT
channel that has been allowed in the Admin menu by entering
the corresponding number from the keypad. If PTT has been
enabled in this handset, the default channel is the lowest allowed
channel as set in the Admin menu.
Enable/Disable Enable turns on PTT mode. Disable turns off PTT mode. PTT
is disabled by default.
If PTT is allowed in the Admin menu and enabled by the user, standby Battery Pack life is decreased to about 30 hours.
Audio volume
Tone volume
Used to adjust volume of PTT audio and tones. The graduated
volume bar indicates the levels. The Audio Volume setting may
be overridden by adjusting volume while the handset is in a
push-to-talk call. Select a volume level by pressing the Up and
Down side buttons and then pressing the OK softkey.
(Additional options may be present. Contact your system administrator for information.)
Push-to-talk operation
Overview The push-to-talk feature allows 3626 WTs to operate in a push-to-
talk (PTT) group broadcast mode in addition to the standard
telephone operation.
The 3626 WT 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 3626 WTs that are monitoring that channel will hear
the transmission.
PTT dialogue is interrupted when you answer a PBX call. When
the PBX call is ended, PTT dialogue resumes if in an active call.
Selecting a channel See Setting User Preferences above.
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 ten 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 unless the PTT call is Terminated (see below).
However, it is possible to easily place a PBX call (see below).
