Abstract
Existing automatic log on/log off systems in telephone systems determine whether or not a workstation is occupied and whether calls can be directed to that workstation by determining whether or not the amplifier that provides the interface between the telephone system and the occupant's headset is plugged into the workstation. Recent headsets have included a connector in the cord between the headset and the amplifier, enabling the occupant to leave the workstation without unplugging the amplifier. However, this defeats the sensing mechanism of the existing automatic log on/log off system. A wireless telephone headset system according to the present invention replaces the existing wired amplifier and headset assembly and includes a detector for determining whether a wireless communication link exists between the headset and the amplifier, and an activator for activating the existing automatic log on/log off system in the telephone system. In the preferred embodiment, the detector senses both interruption and reestablishment of the wireless communication link between the headset and the amplifier, and the activator activates both current-sensing and voltage/resistance-sensing automatic log on/log off systems.
