RJ 12 and RJ14 are two separate models in structured cabling. RJ, which is also known as registered jack, is a connector that is particularly made and used in networking applications. The name ‘Jack’ applies to the female connector, although the standard does not alter the gender of the connector.
These connectors are also related to “modular connectors. The RJ standard is originally designated for the wiring of telephone networks.
Rj12 vs Rj14
The main difference between Rj12 and RJ14 is that Rj12 is used to establish a connection between a single telephone connection, whereas RJ14 is used for two telephone lines. Rj12 is mostly used for phone systems, whereas RJ14 is used for two-line services. Rj12 works on a 6 position and 6 conductors. Meanwhile, Rj14 operates on a 6 position and 4 conductors.
Rj12 is a 6 position 6 conductor wiring types which mean 6 points of the socket will be filled by 6 conductors or cables. Traditional home phones use RJ11, and corporate PBX working with key phones or Digital Phone Systems works with usually RJ12.
In some telephones, configure 3 phone lines (3 CO lines) for an operator to respond to 3 various phone lines. Those kinds of telephones are commonly connected via RJ12 connectors.
RJ14 connector holds 6 points, of which 4 are connected. The pins are 2, 3, 4 and 5. It is applied for an attachment to two analogue telephone lines. It applies 4 wires for connection. It is utilised to join two telephones. It uses a 6P4C connector type.
RJ14 looks similar to the Rj11 connector, but it includes two extra-thin copper strips, which are placed in the grooves underneath the plug.

What is Rj12?
The full name of Rj12 is registered jack 12. It is a connection jack that joins a primary telephone system with private telephone lines by a line circuit. It is a male plug and individually combines with an ameRj12 female jack to secure the connection that is required for the combination.
