British telephone sockets were introduced in their current plug and socket form on 19 November 1981 by British Telecom to allow subscribers to connect their own telephones. The connectors are specified in British Standard BS 6312. Electrical characteristics of the telephone interface are specified by individual network operators, e.g. in British Telecom's SIN 351. Electrical characteristics required of British telephones used to be specified in BS 6305.
They are similar to modular connectors (as used in RJ11), but feature a side-mounted hook, rather than a bottom-mounted one, and are physically incompatible.

Famous quotes containing the words british, telephone and/or sockets:
“Nothing could be more inappropriate to American literature than its English source since the Americans are not British in sensibility.”
—Wallace Stevens (1879–1955)
“A woman spent all Christmas Day in a telephone box without ringing anyone. If someone comes to phone, she leaves the box, then resumes her place afterwards. No one calls her either, but from a window in the street, someone watched her all day, no doubt since they had nothing better to do. The Christmas syndrome.”
—Jean Baudrillard (b. 1929)
“And in their blazing solitude
The stars sang in their sockets through the night:
“Blow bright, blow bright
The coal of this unquickened world.””
—Philip Larkin (1922–1986)
