Bluetooth
an open wireless protocol for exchanging data over short distances from fixed and mobile devices, such as
mobile phones and headsets. It is primarily designed for low power consumption, with a short range (power-
class-dependent: 1 meter, 10 meters, 100 meters) based on low-cost transceiver microchips in each device.
bluetooth makes it possible for these devices to communicate with each other when they are in range. because
the devices use a radio (broadcast) communications system, they do not have to be in line of sight of each other.
DECT
(Digital enhanced Cordless telecommunications). DeCt is an etsI standard for digital portable phones (cordless
home telephones), commonly used for domestic or corporate purposes. DeCt can also be used for wireless
broadband data transfers.
Dongle
a small piece of hardware that connects to a computer, typically portable like a usb Pen. although earlier use
of dongles was to authenticate a piece of software, the word dongle is now widely used to refer to a broadband
wireless adapter. In connection with Jabra® products, dongle is another term for usb bluetooth adapter
(see below).
Dual microphones
Dual microphones increase the amount of captured sound data, enabling the device to more intelligently filter
the background noise. DsP technology then uses the microphones to determine the direction of the sound or
noise based on the sound delay between the two microphones, making it possible to filter out unwanted noise.
the DsP also uses the dual microphone system to significantly reduce stationary noise. to eliminate the “tinny”
effect, sound emanating from the mouth is enhanced and transmitted while all other sound is classified as noise
and is filtered out.
DSP
Digital signal Processing.
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 programs that enable you to configure your Jabra device, update its firmware and control
supported softphones using the buttons on your headset. the Jabra PC suite also includes drivers for various
softphones on the market.
Narrowband audio
narrowband refers to a situation in radio communications where the bandwidth of the message does not
significantly exceed the channel’s coherence bandwidth. It is a common misconception that narrowband refers
to a channel which occupies only a “small” amount of space on the radio spectrum. 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.
Noise Blackout™
Developed by gn netcom engineers, noise blackout™ applies a directional principle to noise cancellation,
reducing only surrounding noise and not distorting the user’s voice. the technology uses dual microphones
to capture sound, intelligently filtering background noise only. Other noise cancellation headsets cancel noise
by cutting away audio frequency and reducing sound quality. used together with advanced DsP technology
and Peakstop™ (audio shock protection) that monitors incoming audio volume, sound is balanced to filter out
background noise, leaving both sides of the call with a natural sounding voice quality.
Pairing
Creates a unique and encrypted link between two bluetooth devices and enables them to communicate with
each other. bluetooth devices will not communicate if they have not been paired.
Softphone
a piece of software for making telephone calls over the Internet using a general purpose computer, 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 phone.
