11. GLOSSARY
DECT
(Digital Enhanced Cordless Telecommunications). DECT is an ETSI standard for digital portable phones (cordless
home telephones), commonly used for domestic or corporate purposes.
Firmware
The software that is embedded in a hardware device, for example any Jabra headset or base.
Hookswitch
The control mechanism that answers and hangs up a call on a telephone. When you place the handset in the
telephone cradle, it depresses the switch hook’s button and hangs up (puts the phone “on hook”).
Jabra PC Suite
A collection of PC software that enables the conguration of the Jabra PRO 9450. The Jabra PC Suite also includes
drivers for various softphones on the market.
Multi-function Button
This button is located on the top of the headset. It is used for call handling on the target phone. Using taps,
double-taps and presses, you can answer calls, end calls, switch between held calls, and more.
Narrowband Audio
Narrowband can also be used with the audio spectrum to describe sounds which occupy a narrow range of
frequencies. In telephony, narrowband is usually considered to cover frequencies 300–3400 Hz. A narrowband
channel occupies less space in the radio spectrum than a wideband channel.
Pairing
Creates a unique and encrypted link between a DECT base and a DECT headset and enables them to communi-
cate with each other. DECT devices will not communicate if they have not been paired.
Softphone
A piece of software for making telephone calls over the Internet using a PC, rather than using dedicated hard-
ware. Often a softphone is designed to behave like a traditional telephone, sometimes appearing as an image of
a phone, with a display panel and buttons with which the user can interact.
A softphone is usually used with a headset connected to the sound card of the PC, or with a USB headset.
Softphone Driver
Establishes a control link between a softphone and your Jabra headset, so you can answer and end, mute and
un-mute, and hold and resume calls using the buttons on your headset. The actual call control functions available
for the headset depend on the capabilities of the softphone and the Jabra headset model.
Wideband Audio
Sometimes also called HD Audio, this is an audio technology used in telephony. It extends the frequency range
of sound travelling over telephone lines, resulting in higher quality voice transmission. The human ear can detect
ranges from 80 hertz to 14,000 hertz. Traditional, or narrowband telephone calls, limit audio frequencies to the
range of 300 to 3400 hertz. Wideband audio eliminates the majority of bandwidth limitations and transmits in
the range of 30 hertz to 7000 hertz or higher.
Dispose of the product according
to local standards and regulations.
