The first location is typically a corporate office. Leased Line: A leased line is a dedicated, fixed-bandwidth, symmetric data connection, it is used to link two locations together. Latency: Delay in processing the flow of data. Most LANs use either Wi-Fi or network cables. A network covering a limited area, such as an office or home. A provider of internet access services (such as ADSL). A means of transmitting voice and data at up to 64kbps per channel, commonly used for lines on a digital telephone system. ISDN: Integrated Services Digital Network. An Internet Protocol address is a string of numbers which acts as an identifier for every device connected to the internet. G.fast: A new copper broadband technology being rolled out by Openreach that is expected to offer speeds up to 330Mb. Traditional copper connections then run from the street cabinet to the premises.įTTP: Fibre To The Premises: Fibre optic cables delivering services directly to the premises from a local POP or telephone exchange. The process by which fibre optic cables are laid from the exchange to the kerb (typically a street cabinet). It is often used to stop unwanted malicious communications arriving via the internet but can also filter and block outgoing data.įTTC: Fibre To The Cabinet. In turn, this also gives businesses a low-latency connection that’s guaranteed to perform all year around.Įthernet: A system for connecting a number of computer systems to form a local area network, with protocols to control the passing of information and to avoid simultaneous transmission by two or more systems.įirewall: A firewall is a barrier between a computer or another network. Ethernet over FTTC uses the existing copper infrastructure that’s used to carry fibre broadband in the last mile, yet provides an uncontended (1:1) Ethernet bandwidth on top. This product bridges the gap between traditional broadband and Ethernet Fibre. Perfect for businesses requiring low cost, private bandwidth. EFM provides symmetrical bandwidth at speeds of up to 20 Mbps with no contention.ĮoFTTC: Ethernet over FTTC. A low cost leased line technology with huge cost savings over traditional fibre leased lines, bringing mission critical connectivity within the reach of small businesses. A system that translates internet domain names into IP numbers.Ī “DNS Server” is a server that performs this kind of translation.ĭongle: In terms of mobile broadband, ‘dongle’ is the word that has been almost universally adopted to describe the small device that receives a mobile broadband signal.ĮFM: Ethernet First Mile. Once a broadband signal leaves your premises it joins a line connecting your neighbours and others to the internet so, the more people using it at once, the slower it can become.ĭNS: Domain Name System. You will often see it used as a synonym of data transfer speed.īonding: Bonding is a way in which you can speed up an FTTC/ADSL broadband connection beyond that which would normally be available by combining multiple lines.Ĭontention: The ratio of broadband users per connection. If we say “high definition video streaming uses a lot of bandwidth” it means a significant amount of your broadband connection’s data transfer capacity is being consumed by that video, which can mean other activities will be slower. A form of ADSL offering up to 24Mbps downloads, and up to 2.5Mbps upstream (for the Annex M version).īandwidth: In the context of broadband, bandwidth is the capacity of a connection. This is the most common way in which broadband is delivered in the UK.ĪDSL2+: Asymmetric Digital Subscriber Line, version 2+. We’ve put together this glossary to help ease your way through the minefield and successfully come out the other side with the right connectivity solution for you.ĤG: The fourth generation of mobile technology currently superseding 3G by offering far superior mobile connection speeds, on a par with ADSL and fibre home broadband.ĪDSL: Asymmetric Digital Subscriber Line. If you’re new to the world of connectivity you’re probably finding you come across a new acronym or term every other day.
