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.

[6]: 56 (e.g. pin headers, screw terminals, board-to-board connectors) Splice or butt connectors (primarily insulation displacement connectors) that permanently join two lengths of wire or cable; In computing, electrical connectors are considered a physical interface and constitute part of the physical layer in the OSI model of networking.
Two pin sizes are standard in the jacks for this size plug body, 2.1 mm (0.083 in) and 2.5 mm (0.098 in), and the plugs should match. If the size is not known, it is difficult to distinguish by eye or measurement between the 2.1mm and 2.5mm ID plugs; some suppliers suggest simple methods.
