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.

Perhaps the most comprehensive known and most discussed feature of ANSI/TIA-568 is the definition of the pin-to-pair assignments, or pinout, between the pins in a connector (a plug or a socket) and the wires in a cable. Pinouts are critical because cables do not function if the pinouts at their two ends aren't correctly matched.
6-pin modular (6P4C or 6P2C), 8-pin modular or 3-position weatherproof connector in accord with TIA-1096-A. [Note 9] 4-prong connector [Note 10] Latvia: 6P2C, Polish national 5-pin [Note 1] Lithuania: 6P2C, Polish national 5-pin [Note 1] Liechtenstein: Reichle-connector, 4-pin Swiss telephone plugs [Note 1] Luxembourg
The connector systems that are commonly used with Eurocard architectures include the original DIN 41612 connector that is also standardized as IEC 60603.2. This is the connector that is used for the VMEbus standard, which was IEEE 1014. The connector known as the 5-row DIN, which is used for the VME64 Extensions standard is IEC 61076-4-113.
Universal EXTension (UEXT) is a connector layout which includes power and three serial buses: Asynchronous, I 2 C, and SPI separately over 10 pins in a 2×5 layout. The connector layout was specified by Olimex Ltd and declared an open-project that is royalty-free in 2011, and was used in all their boards after 2004.
The most commonly used pin outs are Type 6 and Type 10. The latest pin-out added in revision 3.0 of the COM Express specification (available from www.picmg.org) is Type 7. The Type 7 provides up to four 10 GbE interfaces and up to 32 PCIe lanes, making COM Express 3.0 appropriate for data center, server, and high-bandwidth video applications.
Ethernet cable with an M12 X-coded connector in one end and a modular connector in the other. IEC metric screw sized connectors is a family of electrical connectors defined by IEC that are named according to their ISO metric screw thread , namely M5 , M8 and M12 . [ 1 ]
Pin 1 is typically indicated on the body of the connector by a red or raised "V" mark. The corresponding wire in a ribbon cable is usually indicated by red coloration, a raised molded ridge, or markings printed onto the cable insulation. On the connector pin 2 is opposite pin 1, pin 3 is next to pin 1 along the length of the connector, and so on.
