TFIE headset operation

The TFIE Industrial IP Stations TFIE-1 and TFIE-2 support the use of headset.

Zenitel offers the TA-22B Cable/plug box and the headset AK5850HS, but you can also choose to use a 3rd-party headset.

The headset is connected to the pinheader connector J8. There are six connection points: headset speaker, headset microphone and PTT/GND (Press To Talk).

Modes of operation

There are two modes of headset operation. The mode is set from the stations web interface.

Headset mode of operation

Turbine Headset

Toggle Button

In this mode the audio is by default routed to the speaker and microphone of the front panel of the TFIE station (loudspeaking mode). Audio is also routed to the headset speaker in parallel. The headset microphone is disabled.

By pressing the headset PTT button, or the "Toggle" button on the front panel (TFIE-1 only), the audio is routed to the headset, and the audio in the front panel is muted.

When the conversation is ended, the audio is automatically routed back to the front panel, and the headset mic is disabled.

Turbine Headset w/autodetect

In this mode the audio will be routed to the headset as soon as the headset is physically connected. Audio in the front panel is muted.

During a call it is possible to toggle between headset/loudspeaking mode by pressing the "Toggle" button on the front panel. While in loudspeaking mode you can also switch back to headset mode by pressing the PTT button on the headset connection box. The "Toggle" button is disabled if there is no headset detected.

When unplugging the headset, the station will automatically switch to loudspeaking mode.

• Note 1: For a reliable auto-detect function, use software version 4.2.3.7 or later in the TFIE station.
• Note 2: The auto-detect feature is tested with the headsets that Zenitel supplies. The detection might not work with other types of headsets.
