Glossary

  • Asymmetric Digital Subscriber Line (ADSL/ADSL 2): A copper cable that supports broadband though speeds are restricted to around 8Mbps for ADSL and 17Mbps for ADSL 2. (See SDSL).
  • Bandwidth: The speed at which you can upload and download data offline. Higher bandwidths can get more done and faster.
  • Basic Broadband Service: The original term used for our voucher scheme (see voucher scheme).
  • BDUK (Broadband Delivery UK): An agency of the Department of Culture, Media and Sport responsible for the Government’s national broadband and mobile connectivity programme.
  • Broadband: An internet provision that is distinct from the old dial up internet method and offers faster speeds though has no defined speed.
  • Primary Connection Point Cabinet (PCP): The BT green box in the street that connects all the homes and businesses to the broadband network. Differs from a DSLAM cabinet.
  • Commercially Covered: When an area is being provided an improved broadband service through commercial investment. These areas are not in the CDS area and due to State Aid regulation we are not able to comment on them.
  • Contract Upgrade: The process of moving to a new agreement with an ISP that includes the superfast speeds.
  • Device: Technology such as a smartphone or laptop that allows a user to access the internet.
  • Digital Subscriber Line Access Multiplexer (DSLAM): Equipment in BT telephone exchange or cabinet that converts fibre and enables telephone lines to make faster connections and deliver fibre to an area.
  • Download: The amount of data you can transfer from the internet to a device
  • Download Limit: The cap on the data amount an ISP contract allows.
  • Enabled: Connected to a superfast cabinet.
  • Exchange: The BT telephone exchange that receives the cable from the fibre spine and then distributes to the cabinets in the area forming the centre of an area web.
  • Exchange Only: Connecting copper lines that run directly from the property to the BT exchange rather than via a cabinet.
  • Fibre: A method of transferring data by pulsating light along a plastic cable. The speed in which data can be transferred is much faster than copper cabling.
  • Fibre to the Cabinet (FTTC): Fibre connections that run from the exchange to the cabinet to bring an area superfast. The cabling from the property to the cabinet will be on existing copper.
  • Fibre to the Premise (FTTP): Fibre connections that run directly from the exchange to the property without the use of any copper.
  • Fixed Line: Internet delivered over a physical link like a cable or fibre.
  • Fixed Wireless: Internet delivered through a non-physical solution like radio or WiFi.
  • Gainshare: A clawback mechanism under which BT returns part of the public investment when take-up of the new broadband service passes 20%. This only applies in those areas where the company is building superfast connections subsidised by the tax-payer. The money is for reinvestment by CDS to expand Openreach broadband coverage to areas without a service and who will not be connected by commercial investment alone. The gainshare delivery will be concurrent with the wider Phase 2 programme.
  • Get Up To Speed (GUTs): Connecting Devon and Somerset support service to help everyone make the most of the new superfast broadband.
  • Programme Board: The body that oversee the programme and plan and coordinate the various aspects of the project. Positions are filled by cabinet members and chief executives from the Devon and Somerset councils, CDS officers, representatives from the other authorities and the central government arm, BDUK.
  • Internet Service Provider (ISP): the Company who supplies you your internet and may or may not be those who install the infrastructure and service the technology.
  • Intervention Area: The area that is to receive upgraded broadband through the publicly subsidised CDS programme.
  • IP Address: A unique set of numbers that identify your computer or device when it is connected to the internet, like the address and postcode for your house.
  • Landline: The telephone coming in to your home; this is often the same cable that supports the broadband internet.
  • Live: When a cabinet or area is activated and connected to the fibre network.
  • Long Lines: Copper cables that are over 1.6km (just under a mile) in length from a BT cabinet or exchange to a premise can be described as a long line. In many of these cases a home or business will not see significant uplift in speeds even if they are superfast enabled.
  • Megabits per second (Mbps): The amount of data that can be downloaded or uploaded per second.
  • Mobile Broadband: Internet access provided over the mobile networks.
  • Open Market Review (OMR): Working with the commercial sector, this is a critically important analysis to identify which parts of the CDS area will receive a superfast connection via wholly commercial investment and which require public subsidy support from CDS.
  • Out of Programme: When an area does not feature in the current phase of the publicly-subsidised programme and will not be connected.
  • Phase One: The first stage in the Connecting Devon and Somerset superfast broadband rollout has been completed, reaching its target of providing superfast broadband connections to over 278,000 homes and businesses. It has helped to meet the Government ambition of coverage for around 90% of premises across Devon and Somerset in conjunction with commercial provision.
  • Phase Two: The second stage of the CDS rollout programme targeting 35,225 harder to reach homes and businesses. It supports the Government’s ambition to increase superfast broadband coverage to 95% of premises. However, that target is heavily dependent on the commercial sector continuing its provision.
  • Rollout: The process of installing the superfast network across the intervention area is described as the “rollout”.
  • Router: A box in the home or office which enables a WiFi signal to be beamed around the premise so devices can connect to the internet.
  • Satellite Broadband: Internet access provided by a satellite link beaming down coverage to a receiver on your property.
  • Speed: The transfer rate of a broadband connection; we use Mbps as our measure.
  • State Aid: State Aid is any advantage granted by public authorities, such as CDS, which could distort the competition in free market. In order for this to be permitted it needs to be demonstrated that the open market would fail to deliver in these areas without the public authority intervention.
  • Streaming: Watching of film or listening to audio over the internet without having to download.
  • Superfast: Broadband speed that exceeds 24Mbps.
  • Superfast Extension Programme (SEP): Central government term for Phase Two.
  • Symmetrical Digital Subscriber Line (SDSL): Like ADSL only the upload and download speeds are the same.
  • Total Homes Passed: A bit of a misnomer. “THP” is a BT assessment of the number of properties (homes and businesses) capable of accessing superfast broadband; i.e. connected to an enabled cabinet.
  • Ultrafast: Broadband speeds of up to 300 Megabits per second (Mbps).
  • Under Evaluation: An area scheduled for survey by engineers.
  • Unlimited: Where your contract has no caps on the amount of data you can use, usually every month.
  • Uplift: The rate in which your speed increases after moving from standard broadband to superfast. i.e. 10Mbps – 30Mbps.
  • Upload: The amount of data you can transfer on to the internet from a device.
  • Voucher Scheme: A CDS scheme to provide faster speeds to premises with below 2Mbps through a subsidy.
  • Wireless: Refers to a fixed wireless network, a technology that enables an internet connection via microwaves instead of cables relayed to a small radio device attached to the home or business.
