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 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,
itdepresses the switch hook’s button and hangs up (puts the phone “on hook”).
Jabra PC Suite
A collection of communication software that enables the conguration of the BH970 Headset. The Jabra PC Suite also includes drivers
for various communication software on the market.
Multifunction 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 communicate with each other.
DECT devices will not communicate if they have not been paired.
Softphone (Communication Software)
A piece of software for making telephone calls over the Internet using communication software, rather than using dedicated hardware.
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 communication software and your headset so you can answer, end, mute, unmute, hold, and resume
calls using the buttons on your headset. The actual call control functions available for the headset depend on the capabilities of
thecommunication software and the headset model.
Wideband Audio
Sometimes also called HD Audio, and 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
themajority of bandwidth limitations and transmits in the range of 30 hertz to 7000 hertz, or higher.
