Globally recognized standard for wireless communication. Wireless data and voice transfer between headsets, laptops, PCs, mobile phones, PDA ‘s, printers etc. Unlike infrared, Bluetooth does not need a visual connection.


Decibel, measuring unit for the volume of a sound. One decibel is a tenth of a Bel, named after Alexander Graham Bell, the inventor of the telephone. 1 DB is the difference between two sound levels that can be detected by the human ear.


Digital Enhanced Cordless Telephony. Digital and tap-proof transfer technology for wireless telephony.


The new standard, called CAT -iq is an acronym for “Cordless Advanced Technology – internet and quality“. Internet services may be tied in along with the voice transmission, which would normally require WLAN. CAT -iq is based on DECT and is downward compatible to the currently established DECT standard.


Wireless communication (receive/talk) set. Standardized EHS interface.


Is a little piece of hardware that can be connected to a computer, usually portable like a USB-Stick. Earlier, Dongles have been used primarily to authenticate a software installation. Today, the term Dongle is mostly used for a wireless wideband adapter. In connection with Jabra products, Dongle is just a different word for a USB Bluetooth adapter.


Digital Signal Processor. Chips that digitally optimize voice or music. In headsets it is usually used to optimize the voice transfer. For instance, it will suppress echoes and an artificial side tone is added (the own voice can be heard and the sound is natural).


Headset with earphones for both ears, also called binaural with voice output on both ears.


Electronic Hook Switch interface between deskphone and headset can facilitate the following at a minimum: Dial tone transfer, acceptance and ending of a call from the wireless headset.


Basic software that is embedded in the device hardware, for example in a headset or a base station from Jabra.


Generic Access Profile (DECT -GAP) is a transfer protocol for wireless phones and allows for the communication of DECT devices from various manufacturers amongst one another. Wireless phones of various manufacturers can be used next to one another at one DECT base station, because they all use the same transfer protocol and in that way, a manufacturer spanning communication of the devices is possible.


IntelliTone™ regulates the average sound level down to 85dB.


Jabra IntelliPower avoids unnecessary power consumption. When not in use, the display illumination dims down automatically and the headset switches into the stand-by mode. Switching power supply  units are used that have less power consumption yet deliver full performance.


The „Internet Protocol“ (IP) is a network protocol that is commonly used in computer networks and provides the base of the internet.

Mono Headset with earphones for only one ear, also called mono-aural.


With just one button on the headset, calls can conveniently be answered and terminated in remote control. Depending on the respective phone, voice selection, call rejection, redialing and switching between two active phone calls can be controlled. The comfortable operation with just one hand ensures elementary functions, even while being away from the work station.


The MultiPoint™ technology allows for the simultaneous connection of several Bluetooth® enabled devices.


Microphone Short Hook – Interface; EHS-interface.


Multiuse describes a certain product series of the Jabra product portfolio. A Multiuse headset is capable of simultaneous connection the several (up to three) telephone devices.


Narrowband describes sounds within a narrow frequency range between 300 and 3400 Hz.

Noise Cancelling

Noise-suppressing microphone for noisy office environments, like call centers and cubicle based open space offices.

Noise Blackout™

Double microphone that blocks interfering ambient noise even with a short microphone design due to Digital Signal Processing (DSP); ideal for on-the-go.

Noise Filtering

Noise filtering microphone for office environments in an open design.

Omni directional (Omni)

Standard microphone for quiet office environments like private or home offices.


Pairing establishes an absolute and encoded connection between two Bluetooth devices for a bi-directional communication. Bluetooth devices cannot communicate without a prior pairing.


A collection of computer programs that allow the configuration of Jabra devices, to update their firmware and to control supported softphones with the buttons of the headset. The Jabra PC Suite also contains drivers for various softphone programs that are available on the market. www


Technology, that caps sounds/tones higher than 118 dB (e.g. whistles/fax tone).


Deskphone that can use various transfer forms; it is differenciated between analog, ISDN and IP telephony. The counterpart are softphones (see below); these exist only virtually as software and only simulate a real deskphone.


Public Switched Telephone Network – also landline network – describes the entirety of all public, line connected telephone networks.

QD (Quick Disconnect)

Simple change of cables due to plugs with quick disconnect coupling. This allows for an easy connecting and disconnecting of the headset.

Remote Call Control (RCC)

A Remote Call Control (RCC) interface between PC and corded or wireless headset will facilitate at a maximum: Ring tone transfer, call acceptance and termination, muting, volume control but also the automatic but also an automatic status alignment and the reciprocal control between headset and PC/laptop.

Remote Handset Lifter (RHL)

Remote Headset Lifter; standardized interface for all wireless headsets. The mechanical „deskphone receiver“ Jabra GN1000 can be connected to the AU X port.


SafeTone means the parallel integration of the IntelliTone™ – and the PeakStop™ technology.


A software program for internet telephony by using the computer instead of using a specialized hardware. User interface and the behavior of a softphone are often based on common phones, for example by using the image of a telephone with a display and buttons, which the user can use to dial the numbers. Usually, a softphone is used in connection with a headset that is connected through the sound card of the computer or through a USB connection.


TCO (Tjänstemännens Central organization) certifies special ergonomical office products that protect the health of the employees. The TCO quality seal is a worldwide recognized standard in the IT industry, which is also awarded for some time now for headsets (TCO´07).

Telephone conference function

With the integrated conference function, up to 4 headsets (depending on the headset model) can be registered through one base station and can participate in a conversation.


Sensor field at the headset that can be operated by sliding the finger across, e.g. for adjusting the volume.


A touch-screen or sensor screen is a computer input device through which the program flow of a technical device can be directly controlled by touching parts of the screen. The technical conversion of the input is invisible for the user and generates in that way the impression of an immediate control of the computer with the „tip of the finger“.


Unified Communications. A combination of various communication media into one common user interface.

Ultra-Noise Cancelling

Ultra noise-suppressing microphone for extreme noisy office environments, like call centers and cubicle based open space offices.


Universal Serial Bus. Internationally standardized interface with the advantage of a connector that is always the same. It is perfectly suited for the connection of peripheral computer equipment with a medium to high data transfer rate (e.g. PC, mouse, keyboard, printer, headset).


Is sometimes also called a Dongle. A computer needs a Bluetooth adapter to communicate with other Bluetooth devices. Some desktop computers and most newer laptops possess an integrated Bluetooth adapter. But there are also computers that need an external Bluetooth adapter. Bluetooth enables several devices, to communicate through just one adaptor with a computer.


Voice over IP (Internet Protocol). The voice is not transmitted through regular phone lines (analog or ISDN, line oriented transmission), but package oriented. The transmission is carried out e.g. through  Ethernet/Internet (LAN or WLAN).


(Broadband Audio) An audio technology that is used in telephone engineering. Wideband extends the frequency range (150-6800 Hz) of audio signals that are transferred through telephone connections. This leads to a higher quality of the voice transmission. The frequency range of the human voice ranges between 80 and 14.000 Hz. With the common narrowband technology, the audio frequencies are limited to the range between 300 and 3400 Hz.
