Telephone Prefix
A telephone prefix is the first set of digits after the country, and area codes of a telephone number; in the North American Numbering Plan countries (country code +# ), it is the first three digits of a seven-digit phone number, 3-3-4 scheme. In other countries both the prefix and the number may have different lengths. It shows which exchange the remaining numbers refer to. A full telephone number is usually made up of a country code (required for international calls only), area code (required for calls between telephone areas), prefix, and subscriber number. Some places restrict certain prefixes to fax numbers or cell phones only; in other places such dedicated prefixes are not used. As telephone technology advanced, the precise significance of the prefix became blurred in many places; for instance, ''485'' in London, UK, was once the GULliver exchange, but now 44-20-''7485-''xxxx is just considered one of many number blocks served by the CLKEN Kentish Town exchange.

North American Numbering Plan
The North American Numbering Plan (NANP) is a telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1 and has the international calling code ''1''. Some North American countries, most notably Mexico, do not participate in the NANP. The NANP was originally devised in the 1940s by the American Telephone and Telegraph Company (AT&T) for the Bell System and the independent telephone operators in North America. The goal was to unify the diverse local numbering plans that had been established in the preceding decades and prepare the continent for direct-dialing of calls by customers without the involvement of telephone operators. AT&T continued to administer the numbering plan until the breakup of the Bell System, when administration was delegated to the North American Numbering Plan Administrator (NANPA), a service that has been procured from the private sector by the Fede ...

The change affected subscriber numbers in the cities of Birmingham, Edinburgh, Glasgow, Liverpool, London and Manchester which used the Director telephone system. The transition to all-figure dialling occurred between 1966 and 1970 and was initiated by the General Post Office. It was one of the first in a series of changes in the organisation of British telephone numbers. In most areas the change initially only affected the presentation of area codes, but in six multiple exchange director telephone system, director areas such as the 020, London telephone area, the change required the introduction of new local exchange codes. The period of parallel operation of the old and new systems ended in 1970 with the ''ANN: Al ...

Telephone Numbering Plan
A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone number A telephone number is a sequence of digits assigned to a landline telephone subscriber station connected to a telephone line or to a wireless electronic telephony device, such as a radio telephone or a mobile telephone, or to other devices f ...s to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined in each of the administrative regions of the public switched telephone network (PSTN) and in private telephone networks. For public numbering systems, geographic location typically plays a role in the sequence of numbers assigned to each telephone subscriber. Many numbering plan administrators subdivide their territory of service into geographic regions designated by a prefix, often called an area code or ...

Automatic Number Announcement Circuit
An automatic number announcement circuit (ANAC) is a component of a central office of a telephone company that provides a service to installation and service technicians to determine the telephone number of a telephone line. The facility has a telephone number that may be called to listen to an automatic announcement that includes the caller's telephone number. The ANAC facility is useful primarily during the installation of landline telephones to quickly identify one of multiple wire pairs in a bundle or at a termination point. Operation By connecting a test telephone set, a technician calls the local telephone number of the automatic number announcement service. This call is connected to equipment at the central office that uses automatic equipment to announce the telephone number of the line calling in. The main purpose of this system is to allow telephone company technicians to identify the telephone line they are connected to. Automatic number announcement systems are base ...

867-5309/Jenny
"867-5309/Jenny" is a 1981 song written by Alex Call and Jim Keller and performed by Tommy Tutone that was released on the album ''Tommy Tutone 2'', on the Columbia Records label. It peaked at No. 4 on the ''Billboard'' Hot 100 chart in May 1982, and No. 1 on the ''Billboard'' Hot Mainstream Rock Tracks chart in April 1982. The song led to a fad of people dialing 867-5309 and asking for "Jenny". Creation Lead guitarist Jim Keller, interviewed by ''People'' in 1982, said: "Jenny is a regular girl, not a hooker. Friends of mine wrote her name and number on a men's room wall at a bar. I called her on a dare, and we dated for a while. I haven't talked with her since the song became a hit, but I hear she thinks I'm a real jerk for writing it." On March 28, 2008, Tommy Tutone lead singer Tommy Heath stated on the ''WGN Morning News'' that the number was real and it was the number of a girl he knew. As a joke, he wrote it on a bathroom wall in a motel where they were staying. "W ...

Song
A song is a musical composition intended to be performed by the human voice. This is often done at distinct and fixed pitches (melodies) using patterns of sound and silence. Songs contain various forms, such as those including the repetition and variation of sections. Written words created specifically for music, or for which music is specifically created, are called lyrics. If a pre-existing poem is set to composed music in classical music it is an art song. Songs that are sung on repeated pitches without distinct contours and patterns that rise and fall are called chants. Songs composed in a simple style that are learned informally "by ear" are often referred to as folk songs. Songs that are composed for professional singers who sell their recordings or live shows to the mass market are called popular songs. These songs, which have broad appeal, are often composed by professional songwriters, composers, and lyricists. Art songs are composed by trained classical compose ...

555 Telephone Number
The telephone number prefix 555 is a central office code in the North American Numbering Plan, used as the leading part of a group of 10,000 telephone numbers, ''555-XXXX'', in each numbering plan area (NPA) (area code). It has traditionally been used only for the provision of directory assistance, when dialing (area code)-555-1212. The central office code is also used for fictitious telephone numbers in North American television shows, films, video games, and other media in order to prevent practical jokers and curious callers from bothering telephone subscribers and organizations by calling telephone numbers they see in works of fiction. Fictional usage Telephone companies began encouraging the producers of television shows and movies to use the 555 prefix for fictional telephone numbers by the 1960s. Two early examples include '' The Second Time Around'' (1961), which used 555-3485, and ''Panic in Year Zero!'' (1962), which used 555-2106. In television shows made or set ...

Telephone Dial
A rotary dial is a component of a telephone or a telephone switchboard that implements a signaling technology in telecommunications known as pulse dialing. It is used when initiating a telephone call to transmit the destination telephone number to a telephone exchange. On the rotary dial, the digits are arranged in a circular layout, with one finger hole in the finger wheel for each digit. For dialing a digit, the wheel is rotated against spring tension with one finger positioned in the corresponding hole, pulling the wheel with the finger to a stop position given by a mechanical barrier, the finger stop. When released at the finger stop, the wheel returns to its home position driven by the spring at a speed regulated by a governor device. During this return rotation, an electrical switch interrupts the direct current (DC) of the telephone line (local loop) the specific number of times associated with each digit and thereby generates electrical pulses which the telephone exchang ...

Telephone Exchange
A telephone exchange, telephone switch, or central office is a telecommunications system used in the public switched telephone network (PSTN) or in large enterprises. It interconnects telephone subscriber lines or virtual circuits of digital systems to establish telephone calls between subscribers. In historical perspective, telecommunication terms have been used with different semantics over time. The term ''telephone exchange'' is often used synonymously with ''central office'', a Bell System term. Often, a ''central office'' is defined as a building used to house the inside plant equipment of potentially several telephone exchanges, each serving a certain geographical area. Such an area has also been referred to as the exchange or exchange area. In North America, a central office location may also be identified as a ''wire center'', designating a facility to which a telephone is connected and obtains dial tone. For business and billing purposes, telecommunication carriers defi ...

Scotland Yard
Scotland Yard (officially New Scotland Yard) is the headquarters of the Metropolitan Police, the territorial police force responsible for policing Greater London's 32 boroughs, but not the City of London, the square mile that forms London's historic and primary financial centre. Its name derives from the location of the original Metropolitan Police headquarters at 4 Whitehall Place, which also had an entrance on a street called Great Scotland Yard. The Scotland Yard entrance became the public entrance, and over time "Scotland Yard" has come to be used not only as the name of the headquarters building, but also as a metonym for both the Metropolitan Police Service itself and police officers, especially detectives, who serve in it. ''The New York Times'' wrote in 1964 that, just as Wall Street gave its name to New York's financial district, Scotland Yard became the name for police activity in London. The force moved from Great Scotland Yard in 1890, to a newly completed build ...
