Information about Telephone Jack

A telephone plug is a plug which allows a telephone to connect to the local telephone network. It plugs into a socket or jack fixed to the wall or baseboard. The standard for telephone plugs varies from country to country though the RJ11 has become by far the most common. Such jacks are also seen on the body of phones.

Historically the telephone was often owned by the supplier and permanently wired in to the telephone line they supplied but as phone markets became more deregulated there was a need for a simple plug in interface that consumers could use. Many countries initially used their own connectors. For example Bell System companies in the 1960s used a round plug about 40mm in diameter with four prongs about 15mm apart. National connectors remain in service but few are used for new installations.

Sometimes the same connector is used by different countries but wired in different ways, for example telephones in the UK typically use a cord with a BT style plug on one end and a "RJ 11" 6P4C connected to the other but this connector is often wired in the same way as the BT plug rather than according to the RJ11 standard.

List of countries and territories, with the plugs they use

This list covers only single line telephone plugs commonly used in homes and other small installations. Special telephone sets use a variety of special plugs, for example micro ribbon for key telephone systems and the wide array of registered jacks.
