For example, telephone cables in the UK typically have a BS 6312 (UK standard) plug at the wall end and a 6P4C or 6P2C modular connector at the telephone end: this latter may be wired as per the RJ11 standard (with pins 3 and 4), or it may be wired with pins 2 and 5, as a straight-through cable from the BT plug (which uses pins 2 and 5 for the ...
The first types of small modular telephone connectors were created by AT&T in the mid-1960s for the plug-in handset and line cords of the Trimline telephone. [1] Driven by demand for multiple sets in residences with various lengths of cords, the Bell System introduced customer-connectable part kits and telephones, sold through PhoneCenter stores in the early 1970s.

A standard Swedish telephone plug carries one telephone line and has four flat metal pins and one plastic pin. 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 ...
A punch down tool, punchdown tool, IDC tool, or a Krone tool (named after the Krone LSA-PLUS connector), is a small hand tool used by telecommunication and network technicians. It is used for inserting wire into insulation-displacement connectors on punch down blocks, patch panels, keystone modules, and surface mount boxes (also known as ...
A domestic single British telephone line installation will have a single master socket or line box in the premises, which is provided by BT or another service provider: this socket is the demarcation point between the customer-owned and maintained on-premises wiring, and the telephone network.
A cable with a 50-pin connector on one end can support six fully wired 8P8C connectors or Ethernet ports on a patch panel with one spare pair. Alternatively, only the necessary pairs for 10/100 Ethernet can be wired allowing twelve Ethernet ports with a single spare pair. This connector is also used with spring bail locks for SCSI-1 connections.
The wires between the junction box and the exchange are known as the local loop, and the network of wires going to an exchange is known as the access network. The vast majority of houses in the U.S. are wired with 6-position modular jacks with four conductors ( 6P4C ) wired to the house's junction box with copper wires.
