ADSL (Asymmetric Digital Subscriber Line) : ADSL is a type of high-speed broadband Internet connection that transmits data over existing copper phone lines. Requires particular ADSL modem.
Analog : Analog is used to describe a traditional telephone or telephone service. Where sound vibrations are converted into electrical vibrations before they are transmitted over traditional phone lines. Compared with digital systems, an analogue telephone line carries data at low speed.
Bandwidth : The amount of data that can be sent from one computer to another through a particular connection in a certain amount of time. The more bandwidth available, the faster you are able to access information. Usually measured in bits or bytes-per-second.
Broadband : Is a type of data transmission in which a single medium (wire) can carry several channels at once including voice, data and video simultaneously. It is also a general term for different types of high-speed, high-bandwidth connections to the Internet, including Cable and DSL.
Codec : refers to the encoding or decoding of a signal. Codecs refer to the sampling speed at which your voice traffic travels through the Internet.
Cordless : A type of phone where the handset is not connected to a device by a cord, allowing the user to move about while placing or receiving a call.
DECT (Digital Enhanced Cordless Telephone) these cordless phones offer speech quality that is superior to that offered by traditional analogue cordless phones. A DECT phone also has the ability to support multiple handsets.
Dial-up : The traditional connection method for the Internet. It involves connecting a device to a network via a modem and a public telephone network. And is similar to a phone connection, except it is computer devices at the two ends instead of people. Because dial-up access uses normal telephone lines, the quality of the connection is not always good and data rates are limited making it slower than modern broadband methods.
Digital : A way of encoding information. On digital networks, data doesn't need to go though the extra step of being converted to an analogue signal.
DSL (Digital Subscriber Line) : Type of high-speed broadband Internet connection that transmits data over the regular copper wires (phone line), bypassing circuit-switched lines that make up a network giving way to faster data transmission than analog.
Firewall : A security system designed to protect a computer network from unauthorised access, especially via the Internet.
Headset : A device similar in functionality to that of a regular telephone handset but is worn on the head to keep the hands free.
Hub : Is a common connection point for devices in a network, which contains multiple ports.
Modem : A device or program that allows a computer to transmit data over, telephone or cable lines. Computer information is stored digitally, however information transmitted over telephone lines is transmitted in analog waves. A modem converts between analog and digital.
Network : Typically means a group of computers working together. It can also refer to the physical wire etc. connecting the computers
PSTN (Public Switched Telephone Network) : A normal landline copper wired network carrying analog voice data.
Router : Hardware that connects two or more networks of computers together. It is generally located at gateways and used forwards data packets along these networks.
Sampling Speeds : refers to the speed at which your voice will travel through the Internet.
SIP (Session Initiation Protocol): Used for setting up communications sessions on the Internet, such as telephony, presence, events notification and instant messaging. The protocol initiates call setup, routing, authentication and other feature messages to endpoints within an IP domain.
Softphone : A softphone is a multi-media application that works in association with VoiP technology enabling you to make calls direct from your PC or laptop. Appearing as an image of a telephone on your computer, it can be downloaded from our web site.
Software : Computer programmes, instructions or data that tell a computer what to do and can be stored electronically.
USB (Universal serial Bus) : A type of standard connection port used to connect printers, modems and mice.
Voice Box : A digital telephone adaptor that converts analogue phone signal to digital so that it can be sent over your broadband Internet connection.
VoiP (Voice over the Internet Protocol) : Technology for transmitting ordinary telephone calls over the Internet. Also called IP telephony.
