Extension

Displays the extension currently assigned to the handset. This number is for display purposes only; entering it does not assign the extension in the host telephone system.

Push-to-talk (PTT)

The NetLink i640 Wireless Telephone 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.



Audio volume Tone volume

If PTT is allowed in the Admin menu and enabled by the user, standby Battery Pack life is decreased to about 30 hours.

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 NetLink i640 Wireless Telephones to operate in a push-to-talk (PTT) group broadcast mode in addition to the standard telephone operation.

The NetLink i640 Wireless Telephone supports eight multicast channels with the current channel saved in memory on the handset. A PTT call is initiated by pressing the Talk button located on the right side of the handset. All NetLink i640 Wireless Telephones 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 Terminiated (see below). However, it is possible to easily place a PBX call (see below).
