A

Access (to equipment, facilities, services etc.)

The making available of facilities and/or services to another undertaking, under defined conditions, on either an exclusive or non-exclusive basis, for the purpose of providing electronic communications services, including when they are used for the delivery of information society services or broadcast content services. It covers inter alia: access to network elements and associated facilities, which may involve the connection of equipment, by fixed or non-fixed means (in particular this includes access to the local loop and to facilities and services necessary to provide services over the local loop); access to physical infrastructure including buildings, ducts and masts; access to relevant software systems including operational support systems; access to information systems or databases for pre-ordering, provisioning, ordering, maintaining and repair requests, and billing; access to number translation or systems offering equivalent functionality; access to fixed and mobile networks, in particular for roaming; access to conditional access systems for digital television services and access to virtual network services.
 

ADC - Access Deficit Cost

Cover the gap between tariff and costs - Access deficit arises when the tariff specified for access does not cover the cost of providing access.

ADSL - Asymmetric Digital Subscriber Line

A technology that enables, for example, rapid access to interactive broadband services and video on demand through copper wire used in existing local telephone loop plant, In its "2+" iteration, ADSL supports one-way transmission at bit rates up to 24 Mbps on a single pair of copper wires and enables subscribers to connect to data networks and the Internet at speeds from 50 to 200 times faster than current analogue modems operating at 28.8 Kbps.
 

API - Application programme interface

  1. API means the software interfaces between applications, made available by broadcasters or service providers, and the resources in the enhanced digital television equipment for digital television and radio services. The API - also known as middleware - is the underlying technical facility for features such as the Electronic Programme Guide, hard disk Personal Video Recorders (PVRs) and any interactive television service, whether enhanced broadcasting carousel-based services derived from teletext or fully interactive services using a return-channel.  APIs can be grouped into two types, those which are more intensively computational, based on an execution engine and those which are declarative, based on presentation engines.  To date the following APIs have been standardised by a European body, MHEG 5 and the Multimedia Home Platform (MHP). Others are Open TV, Liberate.
  2. Application Programming Interface - is a protocol intended to be used as an interface by software components to communicate with each other. An API may include specifications for routines, data structures, object classes, and variables.
     

Associated facilities

Those associated services, physical infrastructures and other facilities or elements associated with an electronic communications network and/or an electronic communications service which enable and/or support the provision of services via that network and/or service or have the potential to do so, and include, inter alia, buildings or entries to buildings, building wiring, antennae, towers and other supporting constructions, ducts, conduits, masts, manholes, and cabinets.
 

Associated services

Those services associated with an electronic communications network and/or an electronic communications service which enable and/or support the provision of services via that network and/or service or have the potential to do so and include, inter alia, number translation or systems offering equivalent functionality, conditional access systems and electronic programme guides, as well as other services such as identity, location and presence service.
 

ATM - Asynchronous Transfer Mode

Broadband transmission technology which provides the backbone of the world’s telecommunications network. ATM breaks information flows into small fixed-length cells of 53 bytes. Cells of any type of traffic – voice, multimedia, data or video – can be interspersed with each other. ATM operates at speeds of 25, 155 and 622 Mbps.

BEREC - Body of European regulators for electronic communications

BEREC and the BEREC Office were created by Regulation 1211/2009 of the European Parliament and of the Council of 25 November 2009 to assist the Commission and the national regulatory authorities (NRAs) in the implementation of the EU regulatory framework for electronic communications, to give advice on request and on its own initiative to the European institutions and to complement at European level the regulatory tasks performed at national level by the regulatory authorities, all in the aim of creating an internal market for electronic communications. BEREC is composed of the 27 NRAs.

Bitstream access

  1. A form of non-physical or virtual network access, included in Market 5: Wholesale Broadband Access.
  2. A service provided by an incumbent operator whereby a new entrant rents a high speed access link to the customer.

Broadband

A term applied to high speed telecommunications systems, i.e. those capable of simultaneously supporting multiple information formats such as voice, high-speed data services and video services on demand. The Digital Agenda defines three levels of broadband speeds: 2, 30, and 100 Megabit per Second.
 

Broadband Guidelines on State Aid

In December 2012, new rules on state aid for broadband were adopted, replacing the 2009 broadband guidelines. Main changes are the need for a step change, i.e. a substantial improvement of broadband coverage as a result of aid, Aid for minor improvements is excluded under strict conditions aid for ultrafast broadband in under-served areas, is eligible. The new rules include a technology neutral definition for fixed wireless access solutions to fall under the definition of NGA.

Is an internet top level domain generally used or reserved for a country (a sovereign state of a dependent territory, e.g. fr .nl).

CDMA - Code-Division Multiple Access

Code-Division Multiple Access is a digital cellular technology that uses spread-spectrum techniques. CDMA does not assign a specific frequency to each user. Instead, every channel uses the full available spectrum. Individual conversations are encoded with a pseudo-random digital sequence. CDMA is a military technology first used during World War II by the English allies to foil German attempts at jamming transmissions. The allies decided to transmit over several frequencies, instead of one, making it difficult for the Germans to pick up the complete signal.

Digital divide

The digital divide is the gulf between those parts of the population that have access to the internet and other digital technologies, and those sections of the population that do not. There is concern that as so many services (both commercial and governmental) become available online, groups without digital access (caused by, among other things, high cost, lack of skills, location, or a combination of these) will be left behind, and miss out on opportunities in life and in work.

 

Digital Dividend

The digital dividend refers to the radio spectrum which becomes available as a result of the switchover of terrestrial TV broadcast from analogue to digital technology which uses the spectrum more efficiently. This is a unique and once-off opportunity to boost the capacity for providing new and innovative broadcast and wireless communication services. The first step related to the 800 Mhz (790 MHz to 862 MHz) while a second phase, following the decision of WRC 12 to open the band to mobile communications, would cover the 700 MHz band.

F

Financial Instruments

"Innovative" financial instruments are loans, guarantees, EU-support to project bonds, or dedicated equity funds. As compared to the traditional grant instrument, FI have the advantage of attracting more additional investment (leverage). For the Connecting Europe Facility support to the roll-out of broadband, the Commission envisions to use FI as much as possible.

Local Loop

The physical twisted copper pair circuit connecting the network termination point at the subscriber's premises to the main distribution frame or equivalent facility in the fixed public telephone network. The local loop may also include optical elements. The physical circuit connecting the network termination point to a distribution frame or equivalent facility in the fixed public electronic communications network.
 

LLU - Local loop unbundling

Local sub-loop

A partial local loop connecting the network termination point at the subscriber's premises to a concentration point or a specified intermediate access point in the fixed public telephone network.
 

Long Run Incremental Costs (LRIC)

The costs that are directly associated with the production of a business increment, i.e. the additional cost of supplying a service over and above the situation where the service was not provided, assuming all other production activities remain unchanged. 'Long run' means that all factors of production including capital equipment are variable in response to changes in demand due to changes in the volume or in the structure of production, therefore all investments are considered as variable costs.
The 'bottom-up' LRIC modelling approach develops a cost model starting from the expected demand in terms of subscribers and traffic; it then models the efficient network that is required to meet the expected demand, and assesses the related costs according to a theoretical network-engineering model. The purpose of a bottom-up model is to calculate the cost on the basis of an efficient network using the newest technology employed in large-scale networks. This approach differs from a top-down modelling approach, which is based on the undertaking's accounts. In a hybrid modelling approach the bottom-up model is refined by looking at the results of the top-down model. It is also possible to check the plausibility of some of the results of the top-down model by using the bottom-up model.

Net Neutrality

Network neutrality is the principle that all electronic communication passing through a network is treated equally. That all communication is treated equally means that it is treated independent of (i) content, (ii) application, (iii) service, (iv) device, (v) sender address and (vi) receiver address. Under the reformed Telecom Rules, national telecoms regulatory authorities will in particular be required to promote "the ability of end users to access and distribute information or run applications of their choice". This will contribute to strengthening the "neutral character" of the internet in Europe.

 

NGA - Next Generation Access

Access networks which consist wholly or in part of optical elements and which are capable of delivering broadband access services with enhanced characteristics (such as higher throughput) as compared to those provided over already existing copper networks. In most cases NGAs are the result of an upgrade of an already existing copper or co-axial access network.

Such events or actions could compromise the availability, authenticity, integrity and confidentiality of stored or transmitted data as well as related services offered via these networks and systems.
 

Non-discrimination

In relation to interconnection and/or access, an obligation of non-discrimination ensures that an operator applies equivalent conditions in equivalent circumstances to other undertakings providing equivalent services, and provides services and information to others under the same conditions and of the same quality as it provides for its own services, or those of its subsidiaries or partners.

 

NRP - National Regulatory Authority

The body or bodies charged by a Member State with any of the regulatory tasks assigned in the Regulatory framework for telecommunications.

P2P - Peer to Peer Network

In a peer to peer (or P2P) computer network participants are connected with each other, whereby the cumulative bandwidth of network participants is used. P2P networks are typically used for connecting nodes via ad hoc connections. A pure P2P network does not have the notion of clients or servers but only equal peer nodes that simultaneously function as both "clients" and "servers" to the other nodes on the network. Such networks are widely used for sharing content files such as software, audio, video, data or anything in digital format. Real-time data, such as telephony traffic or IPTV, is also passed using P2P technology. The technology itself is legal and applied increasingly in various business models. However, it has also been used for copyright infringements and the dissemination of child sexual abuse images (illegal file sharing).

Roaming

In wireless telecommunications, roaming is a general term that refers to the extending of connectivity service in a location that is different from the home location where the service was registered. Regulation on roaming charges in the European Union is a part of policy of the EU promoting competition, safeguarding consumer interests and enhancing  digital single market. The current roaming rules aim at increasing competition in the roaming market by structural remedies such as enabling consumers to buy roaming services separately from domestic mobile services and providing in the meantime safeguards to consumers in the form or prices caps within European Union and European Economic Area member states.

The designation of a given frequency band for use by one or more types of radio communications services, where appropriate, under specific conditions.

 

State aid to public service broadcasting

The application of State aid rules to public service broadcasting has to take into account a wide number of different elements. The Commission adopted Directive 80/723/EEC of 25 June 1980 on the transparency of financial relations between Member States and public undertakings as well as on financial transparency within certain undertakings. These rules are interpreted by the Court of Justice and the Court of First Instance. The Commission Communication on the application of State aid rules to public service broadcasting sets out the principles to be followed by the Commission in the application of the relevant Articles in the EC Treaty to State funding of public service broadcasting.  More information.

Territorialisation of State aid

Some Member States require film producers receiving State aid to spend a specific proportion of the aid received or of the film budget in the territory of the supporting country. Under the Cinema Communication, the producer must be free to spend at least 20% of the film budget in other Member States without suffering any reduction in the aid provided for under the scheme. In other words, the Commission has until now accepted as an eligibility criteria territorialisation in terms of expenditure of up to 80% of the production budget of an aided film or TV work.
 

Traffic data

Any data processed for the purpose of the conveyance of a communication on an electronic communications network or for the billing thereof. According to the means of communication used, the data needed to convey the communication will vary, but may typically include contact details, time and location data.
