Kingsway Telephone Exchange
Kingsway telephone exchange was a Cold War-era hardened telephone exchange underneath High Holborn in London. Initially built as a deep-level air-raid shelter in the early 1940s, it was instead used as a government communications centre. In 1949 the General Post Office (GPO) took over the building, and in 1956 it became the UK termination point for TAT-1, the first transatlantic telephone cable. Closure of the facility began in the 1980s. It was built together with underground exchanges in Birmingham and Manchester, and was originally covered by a D notice History The Kingsway telephone exchange was built as a deep-level shelter underneath Chancery Lane tube station in the early 1940s, consisting of two east-west aligned tunnels, one on each side of the Central Line. Although intended for use as an air raid shelter, like many of the deep level shelters, it was not used for its intended purpose and was instead used as a government communications centre.

Radio Interference Investigation Group
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manchester
Manchester () is a city in Greater Manchester, England. It had a population of 552,000 in 2021. It is bordered by the Cheshire Plain to the south, the Pennines to the north and east, and the neighbouring city of Salford to the west. The two cities and the surrounding towns form one of the United Kingdom's most populous conurbations, the Greater Manchester Built-up Area, which has a population of 2.87 million. The history of Manchester began with the civilian settlement associated with the Roman fort ('' castra'') of ''Mamucium'' or ''Mancunium'', established in about AD 79 on a sandstone bluff near the confluence of the rivers Medlock and Irwell. Historically part of Lancashire, areas of Cheshire south of the River Mersey were incorporated into Manchester in the 20th century, including Wythenshawe in 1931.

Guardian Telephone Exchange
Guardian Exchange was an underground telephone exchange built in Manchester from 1954 to 1957. It was built together with the Anchor exchange in Birmingham and the Kingsway exchange in London – all believed to provide hardened communications in the event of nuclear war; as well as linking the UK government in London to the US Government in Washington, D.C. by means of a secure and hardened transatlantic telephone cable making landfall near Oban and running through Glasgow, Manchester and Birmingham. Today, the underground site is used for telephone cabling. Constructed at a depth of below 35 metres (115 ft), the tunnels are about 2 metres (80 in) in diameter. The exchange cost around £4 million (approximately £126 million in 2015 prices), part of which was funded by the United Kingdom's NATO partners. History Construction began following the clearance of the land between York Street and Piccadilly Bus Station, for the building of The Piccadilly Plaza complex. The ...

Anchor Exchange
Anchor Exchange was an underground, hardened telephone exchange built in Birmingham, England. Construction commenced in 1953 under the guise of building an underground railway. It opened in September 1957 at a cost of £4 million. It was located nominally on Newhall Street. However its network of tunnels extended from at least the Jewellery Quarter to Southside. It originally formed one of a network of 18 zone switching centres within the UK telephone system that provided trunk switching facilities within its own charge group and to group switching centres (GSC) within an area broadly comprising the West Midlands and central Wales. The exchange formed part of the trunk mechanisation plan commenced in 1939 to permit operators from originating GSCs to dial through to a distant UK subscriber without requiring further operator intervention. Later, it was additionally used to switch subscriber dialled trunk calls after its introduction at Bristol in 1958. It was subsequently au ...

Goods
In economics, goods are items that satisfy human wants and provide utility, for example, to a consumer making a purchase of a satisfying product. A common distinction is made between goods which are transferable, and services, which are not transferable. A good is an "economic good" if it is useful to people but scarce in relation to its demand so that human effort is required to obtain it.Samuelson, P. Anthony., Samuelson, W. (1980). Economics. 11th ed. / New York: McGraw-Hill. In contrast, free goods, such as air, are naturally in abundant supply and need no conscious effort to obtain them. Private goods are things owned by people, such as televisions, living room furniture, wallets, cellular telephones, almost anything owned or used on a daily basis that is not food-related. A consumer good or "final good" is any item that is ultimately consumed, rather than used in the production of another good. For example, a microwave oven or a bicycle that is sold to a consu ...

PINDAR
Pindar (; grc-gre, Πίνδαρος , ; la, Pindarus; ) was an Ancient Greek lyric poet from Thebes. Of the canonical nine lyric poets of ancient Greece, his work is the best preserved. Quintilian wrote, "Of the nine lyric poets, Pindar is by far the greatest, in virtue of his inspired magnificence, the beauty of his thoughts and figures, the rich exuberance of his language and matter, and his rolling flood of eloquence, characteristics which, as Horace rightly held, make him inimitable." His poems can also, however, seem difficult and even peculiar. The Athenian comic playwright Eupolis once remarked that they "are already reduced to silence by the disinclination of the multitude for elegant learning". Some scholars in the modern age also found his poetry perplexing, at least until the 1896 discovery of some poems by his rival Bacchylides; comparisons of their work showed that many of Pindar's idiosyncrasies are typical of archaic genres rather than of only the poet hi ...

Main Distribution Frame
In telephony, a main distribution frame (MDF or main frame) is a signal distribution frame for connecting equipment (inside plant) to cables and pair gain, subscriber carrier equipment (outside plant). Overview The MDF is a termination point within the local telephone exchange where exchange equipment and terminations of local loops are connected by jumper wires at the MDF. All cable copper pairs supplying services through User (telecommunications), user telephone lines are terminated at the MDF and distributed through the MDF to equipment within the local exchange e.g. repeaters and DSLAM. Cables to intermediate distribution frames (IDF) terminate at the MDF. trunk (telecommunications), Trunk cables may terminate on the same MDF or on a separate trunk main distribution frame (TMDF). Like other distribution frames the MDF provides flexibility in assigning facilities, at lower cost and higher capacity than a patch panel. The most common kind of large MDF is a long steel rack ...
