Push-to-talk (PTT)

(NetLink s640 Docking Station only)

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.

Overview This push-to-talk functionality is transferred to the NetLink s640 Docking Station when the NetLink i640 Wireless Telephone is placed in the docking cradle. The instructions below that refer to the Docking Station assume that there is an activated NetLink i640 Wireless Telephone in the docking cradle of the NetLink s640 Docking Station.

The NetLink i640 Wireless Telephone supports eight channels with the current channel saved in memory on the NetLink i640 Wireless Telephone. A PTT call is initiated by pressing the CONF button located at the bottom of the Docking Station keypad. All NetLink i640 Wireless Telephones and Docking Stations 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.

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).

Selecting a channel The channel for the Docking Station is selected in the NetLink i640 Wireless Telephone per user guide instructions for that device. The channel for the handset is set in the User Preference menu described in the handset user guide.

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.

Initiating a call Press and hold the CONF button to activate the channel before talking. The display will show Transmitting and you may begin talking.

Transmitting Once a call has been initiated, continue to hold the CONF button and talk into the speakerphone (i.e. talk at the handset like you would for a regular speakerphone call). When the CONF button is released, the NetLink Docking Station then enters the waiting state where it monitors the channel for up to ten seconds.

Initiate subsequent transmissions by pressing the CONF button on any Docking Station or the PTT radio control button on any NetLink i640 Wireless Telephone using the same channel. The user can start talking immediately. The display screen shows the current active channel.

If no transmission occurs during the ten-second countdown period, the Docking Station reverts to the idle state.
