Following the granting of a patent to Alexander Graham Bell in 1876, and the creation of the Bell Telephone Company, USA:
Telecommunications in the United Kingdom have evolved from the early days of the telegraph to modern broadband and mobile phone networks with Internet services.
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.
This timeline of the telephone covers landline, radio, and cellular telephony technologies and provides many important dates in the history of the telephone.
Mercury Communications was a national telephone company in the United Kingdom, formed in 1981 as a subsidiary of Cable & Wireless, to challenge the then-monopoly of British Telecom (BT). Although it proved only moderately successful at challenging BT's dominance, it led the way for new communication companies to attempt the same.
The Jewellery Quarter is an area of central Birmingham, UK, in the north-western area of Birmingham City Centre, with a population of around 19,000 people in a 1.07-square-kilometre (264-acre) area.
The invention of the telephone was the culmination of work done by many individuals, and led to an array of lawsuits relating to the patent claims of several individuals and numerous companies.
Northwestern Bell Telephone Company served the states of the upper Midwest opposite the Southwestern Bell area, including Iowa, Minnesota, South Dakota, North Dakota, and Nebraska.
The BT Archives is an archive preserving the documentary heritage of the British telecoms company BT and its public sector predecessors. It is designated an official place of deposit for Public Records, for those records created prior to BT's privatisation in 1984.
17 & 19 Newhall Street is a red brick and architectural terracotta Grade I listed building, situated on the corner of Newhall Street and Edmund Street in the city centre of Birmingham, England. Although its official name is 17 & 19 Newhall Street, it is popularly known as The Exchange, and was previously known as the Bell Edison Telephone Building.
The 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 (GPO) in 1912.

The British Telecom microwave network was a network of point-to-point microwave radio links in the United Kingdom, operated at first by the General Post Office, and subsequently by its successor BT plc. From the late 1950s to the 1980s it provided a large part of BT's trunk communications capacity, and carried telephone, television and radar signals and digital data, both civil and military. Its use of line-of-sight microwave transmission was particularly important during the Cold War for its resilience against nuclear attack. It was rendered obsolete, at least for normal civilian purposes, by the installation of a national optical fibre communication network with considerably higher reliability and vastly greater capacity.
TXK was a range of Crossbar exchanges used by the British Post Office telephone network, subsequently BT, between 1964 and 1994. TXC was used as the designation at first, but this was later changed as TXC sounded too much like TXE the code used for later electronic exchanges. Prior to this the GPO had standardised on Strowger for automatic switching and had resisted the adoption of Crossbar, preferring to wait for its electronic switching research to bear fruit. The development of electronic systems however took longer than anticipated and the British equipment manufacturers, particularly Automatic Telephone & Electric (ATE), which later became part of the Plessey group feared that continuing to focus the bulk of their production on Strowger equipment would harm their export sales as Crossbar had already become popular throughout the world.

Alexander Graham Bell honors and tributes include honors bestowed upon him and awards named for him.
The Volta Laboratory and the Volta Bureau were created in Georgetown, Washington, D.C. by Alexander Graham Bell.(19/20th-century scientist and inventor best known for his work on the telephone)
The General Post Office (GPO) was the state postal system and telecommunications carrier of the United Kingdom until 1969. Before the Acts of Union 1707, it was the postal system of the Kingdom of England, established by Charles II in 1660. Similar General Post Offices were established across the British Empire. In 1969 the GPO was abolished and the assets transferred to The Post Office, changing it from a Department of State to a statutory corporation. In 1980, the telecommunications and postal sides were split prior to British Telecommunications' conversion into a totally separate publicly owned corporation the following year as a result of the British Telecommunications Act 1981. For the more recent history of the postal system in the United Kingdom, see the articles Royal Mail and Post Office Ltd.
The Telephone Cases, 126 U.S. 1 (1888), were a series of US court cases in the 1870s and the 1880s related to the invention of the telephone, which culminated in the 1888 decision of the US Supreme Court upholding the priority of the patents belonging to Alexander Graham Bell. Those telephone patents were relied on by the American Bell Telephone Company and the Bell System although they had also acquired critical microphone patents from Emile Berliner.
The Cities of Manchester and Salford and some surrounding urban areas such as Stockport, Oldham and Bolton,, were the location of several advances in the development of telephony in the United Kingdom. A Manchester company installed the country's first regular telephone system in the city, wiring solutions which were adopted across Britain were initiated in Manchester and Stockport, the city was (arguably) the site of the UK's first telephone exchange and a service which was the forerunner of modern mobile phones was controlled from the city.
