A video-ready access device ( VRAD ) provides digital subscriber line access and high-definition television programming to customers subscribed to IPTV services such as AT&T 's U-verse , Bell Canada 's Bell Fibe TV , Claro Puerto Rico 's Claro TV , and Telus 's Optik TV . VRAD equipment manufactured by Alcatel-Lucent can be configured to support between 48 and 864 lines per box. The VRAD boxes are composed of circuit boards providing service, fed by fiber-optic cable.

81-452: There are 2 types of VRAD systems currently used by AT&T: FTTN (fiber to the node), and FTTP (fiber to the premises). FTTN, widely used where copper facilities exist in established neighborhoods, uses an Alcatel-Lucent 7330 Intelligent Services Access Manager (ISAM) shelf, which uses the existing copper wiring to customers' homes, leading to distance limitations from the VRAD cabinet to

162-467: A 12 VDC power supply fed over several tens of meters of cable. Power line networking deployments also rely on FTTC. Using the IEEE P1901 protocol (or its predecessor HomePlug AV ) existing electric service cables move up to 1 Gbit/s from the curb/pole/cabinet into every AC electrical outlet in the home—coverage equivalent to a robust Wi-Fi implementation, with the added advantage of

243-544: A BBFC 15 certificate at any time of day provided a PIN -protected system is in place to restrict access to those authorised to view it. The broadcasting of pornography with a BBFC R18 certificate is not permitted. In 2010 Ofcom revoked the licences of four free-to-air television channels for promoting adult chat services during daytime hours and transmitting content that was too sexually explicit. The companies involved were fined £157,250. Ofcom's jurisdiction does not cover television and radio channels which are broadcast in

324-408: A bidding process. Most of the procedures in place have been inherited from the systems used by the previous regulators. However, Ofcom may change some of these processes in future. Ofcom protects the radio spectrum in a number of ways: In October 2010 the government announced plans for Ofcom to inherit the functions of Postcomm as part of a wider set of public service sell-off measures. Following

405-517: A company. On 22 July 2011, it was reported that Ofcom had begun an investigation into whether the phone-hacking scandal may have changed BSkyB's status as the "fit and proper" holder of a UK broadcasting licence. On the same day Ed Richards , the then chief executive of Ofcom, replied to Simon Hughes MP, Don Foster MP and Tim Farron MP following a letter which they had written to him on 8 July concerning News Corporation's shareholding in BSkyB. In

486-747: A consultation over the Online Harms White Paper published by the UK government in April 2019, the government announced in February 2020 that it intended Ofcom to have a greater role in Internet regulation to protect users from "harmful and illegal content". In July 2022, Ofcom received additional tools to prevent, identify and remove any content that depicts child sexual abuse and exploitation. These tools will be introduced through an amendment to

567-533: A contract to monitor the National Assembly for Wales and Welsh Government . It was subsequently reported that the contract had not been put out to tender and that Huw Roberts and Nerys Evans held positions for both Deryn and Ofcom. The contract was terminated and Ofcom concluded that it had broken its own procurement rules. Abu Dhabi TV , owned by the Abu Dhabi Media state enterprise,

648-432: A halfway measure between fixed wireless and FTTH, with special advantages for smart appliances and electric vehicles that rely on PLC use already. Operators around the world have been rolling out high-speed Internet access networks since the mid-2000s. Some used a network topology known as Active Ethernet Point-to-Point to deliver services from its central office directly into subscribers' homes. Fiber termination

729-457: A list of measures to promote the deployment of fast broadband and next-generation access networks. Portugal Telecom plans to complete its fiber-to-the-home nationwide roll out by 2020. Currently 200 Mbit/s down, 100 Mbit/s up costs €22 per month. Between September 2017 and March 2019, the number of European FTTH and FTTB subscribers increased by nearly 16%. By 2025, the total number of premises passed by FTTH and FTTB infrastructure

810-426: A location. Each switching cabinet can handle up to 1,000 customers, although 400–500 is more typical. This neighborhood equipment performs layer 2 switching or layer 3 switching and routing, offloading full layer 3 routing to the carrier's central office. The IEEE 802.3ah standard enables service providers to deliver up to 1000 Mbit/s , full-duplex , over one single-mode optical fiber FTTP, depending on

891-428: A lot of bandwidth, but they cost more because of the fiber and the equipment in the central office. Direct fiber is generally favored by new entrants and competitive operators. A benefit is that no layer 2 networking technologies are excluded, whether passive optical network (PON), active optical network (AON), or other. Any form of regulatory remedy is possible using this topology. More commonly, each fiber leaving

A similar network called a hybrid fiber-coaxial (HFC) network is used by cable television operators but is usually not synonymous with "fiber In the loop", although similar advanced services are provided by

1053-512: A national minority, property, birth or age." However, there is concern that Ofcom's broad definition of hate speech can easily result in the unjustified censorship of controversial opinions, however legitimate they might be. Ofcom has received criticism for incurring unnecessary costs as a result of "extravagant Thames-side offices" and a "top-heavy salary bill", for inflexibility in its regulation of commercial radio, and for "poor service". In response to ongoing expenditure concerns, Ofcom made

1134-710: A number of changes to the way phone calls to UK service numbers would be charged. Under the new legislation, which was promoted by an information campaign entitled UK Calling , call charges must be clearly stated on all materials that advertise a service number. The changes came after research found that callers are often confused about service call charges, and thus can avoid calling these numbers. The July 2015 changes also saw 'freephone numbers' 0800 and 0808 become free to call from both mobiles and landlines. In March 2016, Ofcom launched an interactive "Mobile coverage and fixed broadband checker", allowing people to check mobile coverage and broadband speeds via their post code. Ofcom

Under Cameron's subsequent premiership of the 2010 UK coalition government , the Public Bodies Act 2011 did remove or modify several of Ofcom's duties, although it did not substantially reduce Ofcom's remit. On 1 October 2011, Ofcom took over responsibility for regulating

1458-436: A single cable for power and data. By avoiding new cable and its cost and liabilities, FTTC costs less to deploy. However, it also has historically had lower bandwidth potential than FTTP. In practice, the relative advantage of fiber depends on the bandwidth available for backhaul , usage-based billing restrictions that prevent full use of last-mile capabilities, and customer premises equipment and maintenance restrictions, and

1782-442: Is FTTB. Fiber to the curb/cabinet (FTTC) is a telecommunications system based on fiber-optic cables run to a platform that serves several customers. Each of these customers has a connection to this platform via coaxial cable or twisted pair . The "curb" is an abstraction and can just as easily mean a pole-mounted device or communications closet or shed. Typically any system terminating fiber within 300 m (1,000 ft) of

1863-759: Is a common way of delivering triple- and quad-play (voice, video, data, and mobile) services over both fiber and hybrid fiber-coaxial (HFC) networks. Active PPPoE uses dedicated fiber from an operator's central office all the way to the subscribers' homes, while hybrid networks (often FTTN) use it to transport data via fiber to an intermediate point to ensure sufficiently high throughput speeds over last-mile copper connections. This approach has become increasingly popular in recent years with telecoms service providers in both North America ( AT&T , Telus , for example) and Europe's Fastweb , Telecom Italia , Telekom Austria and Deutsche Telekom , for example. Google has also looked into this approach, amongst others, as

1944-457: Is also the competition authority for telecoms, enforcing remedies in markets where it believes dominant operators may have a potentially harmful influence on competition or consumers. One of its most high-profile interventions was to require BT to split its wholesale and retail arms into separate companies, bringing about the creation of Openreach which supplies wholesale services to both BT Retail and competing providers. On 1 July 2015, Ofcom made

2025-712: Is expected to reach 187 million throughout Europe. Google Fiber provides speed of up to 8 Gbit/s . Active Line Access is an evolving standard for the provision of services over FTTP networks in the United Kingdom proposed by the regulator Ofcom and developed by the Network Interoperability Consultative Committee. Most FTTH deployments follow one of four primary architecture types: centralized split, distributed split, star architecture, or daisy-chaining. Fiber network developers choose architectures based on

The process of licensing varies depending on the type of use required. Some licences simply have to be applied and paid for; other commercial licences are subject to

2187-449: Is saved by not running fiber to the home. Fiber to the x is the key method used to drive next-generation access ( NGA ), which describes a significant upgrade to the broadband available by making a step change in speed and quality of the service. This is typically thought of as asymmetrical with a download speed of 24 Mbit/s plus and a fast upload speed. Ofcom have defined super-fast broadband as "broadband products that provide

2268-417: Is sometimes given the acronym FTTLA (fiber-to-the-last-amplifier) when it replaces analog amplifiers up to the last one before the customer (or neighborhood of customers). FTTC allows delivery of broadband services such as high-speed internet. Usually, existing wire is used with communications protocols such as broadband cable access (typically DOCSIS ) or some form of DSL connecting the curb/cabinet and

3483-1098: The United States, in Chattanooga , Tennessee , despite being conducted by power utility EPB , was FTTH rather than FTTC, reaching every subscriber in a 600-square-mile area. Monthly pricing of US$ 350 reflected this generally high cost of deployment. However, Chattanooga EPB has reduced the monthly pricing to US$ 70/month. Historically, both telephone and cable companies avoided hybrid networks using several different modes of transport from their point of presence into customer premises. The increased competitive cost pressure, availability of three different existing wire solutions, smart grid deployment requirements (as in Chattanooga), and better hybrid networking tools (with major vendors like Alcatel-Lucent and Qualcomm Atheros , and Wi-Fi solutions for edge networks , IEEE 1905 and IEEE 802.21 protocol efforts and SNMP improvements) all make FTTC deployments more likely in areas uneconomic to serve with FTTP/FTTH. In effect FTTC serves as

3564-533: The biggest overhaul of telephoning in over a decade. On 1 January 2016, the regulation of video on demand was transferred to Ofcom from ATVOD , the Authority for Television on Demand. The Digital Economy Act 2017 extended Ofcom's remit and powers. Ofcom were given powers concerning the minimum broadband speed provided by Internet service providers , the ability to financially penalise communications providers for failing to comply with licence commitments and

3645-543: The building can offer the highest speeds since the remaining segments can use standard Ethernet or coaxial cable. Fiber is often said to be "future-proof" because the data rate of the connection is usually limited by the terminal equipment rather than the fiber, permitting substantial speed improvements by equipment upgrades before the fiber itself must be upgraded. Still, the type and length of employed fibers chosen, e.g. multimode vs. single-mode, are critical for applicability for future connections of over 1 Gbit/s . With

3726-434: The cabinet is usually less than one mile in radius and can contain several hundred customers. FTTN allows delivery of broadband services such as high-speed internet. High-speed communications protocols such as broadband cable access (typically DOCSIS ) or some form of digital subscriber line (DSL) are used between the cabinet and the customers. Data rates vary according to the exact protocol used and according to how close

3807-458: The central office into a large switched Ethernet network. Ethernet in the first mile deployments follow a point to point or star network topology and are often based on Fast Ethernet speeds of up to 100 Mbit/s . Such networks are identical to Ethernet computer networks used in businesses and academic institutions, except that their purpose is to connect homes and buildings to a central office rather than to connect computers and printers within

3888-405: The central office is actually shared by many customers. It is not until such a fiber gets relatively close to the customers that it is split into individual customer-specific fibers. AONs and PONs both achieve this split. AONs rely on electrically powered network equipment to distribute the signal, such as a switch or router . Normally, signals need an optical-electrical-optical transformation in

However, 1 Gbit/s Ethernet over fiber can easily reach tens of kilometers. Therefore, FTTP has been selected by every major communications provider in the world to carry data over long 1 Gbit/s symmetrical connections directly to consumer homes. FTTP configurations that bring fiber directly into

4131-682: The cost of running fiber that can vary widely with geography and building type. In the United States and Canada, the largest deployment of FTTC was carried out by BellSouth Telecommunications . With the acquisition of BellSouth by AT&T , deployment of FTTC will end. Future deployments will be based on either FTTN or FTTP. Existing FTTC plant may be removed and replaced with FTTP. Verizon , meanwhile, announced in March 2010 they were winding down Verizon FiOS expansion, concentrating on completing their network in areas that already had FiOS franchises but were not deploying to new areas, suggesting that FTTH

4212-435: The customer is to the cabinet. Unlike FTTP, FTTN often uses existing coaxial or twisted-pair infrastructure to provide last mile service and is thus less costly to deploy. In the long term, however, its bandwidth potential is limited relative to implementations that bring the fiber still closer to the subscriber. A variant of this technique for cable television providers is used in a hybrid fiber-coaxial (HFC) system. It

4293-421: The customer premises equipment would be described as FTTC. Fiber to the node or neighborhood (FTTN), sometimes identified with and sometimes distinguished from fiber to the cabinet (FTTC), is a telecommunication architecture based on fiber-optic cables run to a cabinet serving a neighborhood. Customers typically connect to this cabinet using traditional coaxial cable or twisted pair wiring. The area served by

4374-449: The customer's home. The 7330 ISAM is an internet protocol DSL access multiplexer that supports VDSL and ADSL protocols. The FTTP system uses an Alcatel-Lucent 7340 ISAM shelf, which is mostly used in areas such as new neighborhoods or large-scale developments where fiber can be run to the household, removing the distance limitations of copper. The 7340 then connects to a Primary Flexibility Point , which distributes service to homes in

4455-602: The customers. In these protocols, the data rates vary according to the exact protocol used and according to how close the customer is to the cabinet. Where it is feasible to run new cable, both fiber and copper Ethernet are capable of connecting the "curb" with a full 100 Mbit/s or 1 Gbit/s connection. Even using relatively cheap outdoor category 5 copper over hundreds of meters, all Ethernet protocols including power over Ethernet (PoE) are supported . Most fixed wireless technologies rely on PoE, including Motorola Canopy , which has low-power radios capable of running on

4536-407: The distance exceeds 100 m (300 ft). Fiber to the premises (FTTP) is a form of fiber-optic communication delivery in which an optical fiber is run in an optical distribution network from the central office all the way to the premises occupied by the subscriber. The term "FTTP" has become ambiguous and may also refer to FTTC where the fiber terminates at a utility pole without reaching
