GPO Telephones
The General Post Office (GPO) of the United Kingdom carried the sole responsibility for providing telecommunication services across the country with the exception of Hull. The GPO issued a range of telephone instruments to telephone service subscribers that were matched in function and performance to its telephone exchanges. General history Until October 1969, the GPO had a monopoly on the provision of all telephone lines and telephones within the UK, other than in Kingston upon Hull, which for historical reasons was unique in maintaining its own municipal telephone service. From the 1st of October 1969, the Post Office Corporation replaced the General Post Office with ownership of the former GPO business. Customers of the PO (known internally as "subs", short for 'subscribers') did not own their telephones. They were instead rented from the GPO, together with the house wiring and the wiring connecting the house to the local network at a connection point known as a DP (distributi ...

General Post Office
The General Post Office (GPO) was the state postal system and telecommunications carrier of the United Kingdom until 1969. Established in England in the 17th century, the GPO was a state monopoly covering the dispatch of items from a specific sender to a specific receiver (which was to be of great importance when new forms of communication were invented); it was overseen by a Government minister, the Postmaster General. Over time its remit was extended to Scotland and Ireland, and across parts of the British Empire. The GPO was abolished by the Post Office Act 1969, which transferred its assets to the Post Office, so changing it from a Department of State to a statutory corporation. Responsibility for telecommunications was given to Post Office Telecommunications, the successor of the GPO Telegraph and Telephones department. In 1980, the telecommunications and postal sides were split prior to British Telecommunications' conversion into a totally separate publicly owned c ...

Anthony Wedgwood Benn
Anthony Neil Wedgwood Benn (3 April 1925 – 14 March 2014), known between 1960 and 1963 as Viscount Stansgate, was a British Labour Party politician and political activist who served as a Cabinet minister in the 1960s and 1970s. He was the Member of Parliament for Bristol South East and Chesterfield for 47 of the 51 years between 1950 and 2001. He later served as President of the Stop the War Coalition from 2001 to 2014. The son of a Liberal and later Labour Party politician, Benn was born in Westminster and privately educated at Westminster School. He was elected for Bristol South East at the 1950 general election but on his father's death he inherited his peerage, which prevented him from continuing to serve as an MP. He fought to remain in the House of Commons and campaigned for the ability to renounce the title, a campaign which eventually succeeded with the Peerage Act 1963. He was an active member of the Fabian Society and served as chairman from 1964 to 1965. He ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Telecommunications In The United Kingdom
Telecommunications in the United Kingdom have evolved from the early days of the telegraph to modern fibre broadband and high-speed 5G networks. History National Telephone Company (NTC) was a British telephone company from 1881 until 1911, which brought together smaller local companies in the early years of the telephone. Under the Telephone Transfer Act 1911 it was taken over by the General Post Office, General Post Office (GPO) in 1912. The telephone service in the United Kingdom was originally provided by private companies and local city councils, but by 1912–13 all except the telephone service of Kingston upon Hull, Yorkshire and Guernsey had been bought out by the General Post Office. Post Office Telephones also operated telephone services in Jersey and the Isle of Man until 1969 when the islands took over responsibility for their own postal and telephone services. Post Office Telephones was reorganised in 1980–81 as ''British Telecommunications'' (''British Telecom' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PABX
A business telephone system is a telephone system typically used in business environments, encompassing the range of technology from the key telephone system (KTS) to the private branch exchange (PBX). A business telephone system differs from an installation of several telephones with multiple central office (CO) lines in that the CO lines used are directly controllable in key telephone systems from multiple telephone stations, and that such a system often provides additional features for call handling. Business telephone systems are often broadly classified into key telephone systems and private branch exchanges, but many combinations (hybrid telephone systems) exist. A key telephone system was originally distinguished from a private branch exchange in that it did not require an operator or attendant at a switchboard to establish connections between the central office trunks and stations, or between stations. Technologically, private branch exchanges share lineage with central ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DTMF
Dual-tone multi-frequency (DTMF) signaling is a telecommunication signaling system using the voice-frequency band over telephone lines between telephone equipment and other communications devices and switching centers. DTMF was first developed in the Bell System in the United States, and became known under the trademark Touch-Tone for use in push-button telephones, starting in 1963. The DTMF frequencies are standardized in ITU-T Recommendation Q.23. The signaling system is also known as ''MF4'' in the United Kingdom, as ''MFV'' in Germany, and ''Digitone'' in Canada. Touch-tone dialing with a telephone keypad gradually replaced the use of rotary dials and has become the industry standard in telephony to control equipment and signal user intent. The signaling on trunks in the telephone network uses a different type of multi-frequency signaling. Multifrequency signaling Before the development of DTMF, telephone numbers were dialed with rotary dials for loop-disconnect (LD) ...

Pulse Dialing
Pulse dialing is a signaling technology in telecommunications in which a direct current local loop circuit is interrupted according to a defined coding system for each signal transmitted, usually a digit. This lends the method the often used name loop disconnect dialing. In the most common variant of pulse dialing, decadic dialing, each of the ten Arabic numerals are encoded in a sequence of up to ten pulses. The most common version decodes the digits 1 through 9, as one to nine pulses, respectively, and the digit 0 as ten pulses. Historically, the most common device to produce such pulse trains is the rotary dial of the telephone, lending the technology another name, rotary dialing. The pulse repetition rate was historically determined based on the response time needed for electromechanical switching systems to operate reliably. Most telephone systems used the nominal rate of ten pulses per second, but operator dialing within and between central offices often used pulse r ...

Dial (of Telephone)
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 as a succession of individual digits. 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 electric ...

Postmaster-General
A Postmaster General, in Anglosphere countries, is the chief executive officer of the postal service of that country, a ministerial office responsible for overseeing all other postmasters. History The practice of having a government official responsible for overseeing the delivery of mail throughout the nation originated in England. A 'Master of the Posts' is mentioned in the ''King's Book of Payments'', with a payment of £100 being authorised for Sir Brian Tuke as 'Master of the King's Post' in February 1512. In 1517, he was appointed to the office of 'Governor of the King's Posts', a precursor to the office of Postmaster General of the United Kingdom, by Henry VIII Henry VIII (28 June 149128 January 1547) was King of England from 22 April 1509 until his death in 1547. Henry is known for his Wives of Henry VIII, six marriages and his efforts to have his first marriage (to Catherine of Aragon) annulled. ....Walker (1938), p. 37 In 1609, it was decreed that letter ...
