Swedish telephone plugs & sockets

The design is used only by Televerket (now Telia Company) in Sweden and older Póstur og Sími (now Síminn) installations in Iceland (RJ11 and a data/voice standard using an 8P8C modular connector are used in more recent buildings).

When all sockets on a line are connected in parallel only the lower pins on a Swedish Standard plug (middle connectors on RJ-plugs) are used.

Parallel connection of sockets is now allowed but can be considered bad practice by some, and makes DSL splitter installation more cumbersome.

In addition to the standard Swedish plugs and sockets, RJ11 connectors are quite common, especially in offices.

6P6C modular plugs are also used for telephony, but only for certain telephone exchange systems - never for direct connection to the PSTN.
