RJ14

RJ14 - Registered Jack 14 - is a connector that can accommodate up to two phone lines. RJ14 is often used when there are multiple lines leading to a single telephone unit.

It is also common to have an RJ14 connection that goes through a junction box and is then divided into two RJ11

RJ11 - Registered Jack 11 - is used for the landline telephone. It is an international standard that is used to connect the landline telephone to the Telecommunications network.
RJ11 uses a 6-slot connector. In it RJ11 has 6 slots (positions) and two conductors, the standard is written 6P2C. The information transmitted on the line can be digital (DSL) or analog. The telephone cable that arrives at the subscriber h
connections that lead to two separate phone units.

RJ12 - Registered Jack 12 - is a standard of the same family as RJ11, RJ13 and RJ14. The same six-slot connector is used. RJ12 has 3 pairs of copper strands allowing the exchange of information on 3 lines, the other standards allow exchanges only on one or two lines.
RJ12 allows the connectivity of telephone lines in companies while in general RJ11 is aimed at individuals. The terms Tip and Ring are used to ref
and RJ14 use connectors of the same size, so it's pretty easy to confuse them with each other.

RJ11-12-14 connectors

The contacts always go by 2, this is the minimum number of strands to ensure the telecommunication service.
They are grouped in pairs to optimize performance, these pairs are called twisted pairs.

standard, uses two strands and can accommodate only one telephone unit, it is the simplest assembly.

A number of other different connectors are used. There are the 6P6C, 6P4C and 6P2C. The first digit indicates the number of positions in the connector and the second the actual contacts.
Thus, the 6P6C connector has all its slots with contact points, it corresponds to the RJ12

and RJ14 connections, it is best to use 6P4C connectors and cables that have two twisted pairs (i.e. 4 strands). It may cost a little more, but you gain flexibility by having the right equipment for both wiring standards.
It may also be interesting to pre-wire a house or establishment with RJ14, even if the project is to use a single phone, so that one will not have to rewire if one decides to add another unit or line to the installation.

RJ14 / RJ45 comparison

The RJ14 comes with a 6-position connector (4 are used), the RJ45 comes with an 8-position connector. In the RJ45, all 8 pins are used as conductors for 8-strand connections, in the RJ14, only 4-pin connections are used for 4-strand connections.

RJ14 therefore has a type of 6P4C connector. RJ45 has an 8P8C connector type which is an 8-position, 8-contact connector type. Its size is therefore different and it does not physically plug into an RJ11

The RJ45 is mainly used for Ethernet or computer network connections and the RJ14 is used for two-line telephone communications, it can also be used when 2 lines are connected to a single connection.
In RJ14, the positions of the strands are pin 2 for negative wiring and pin 5 for positive. In RJ45, 4 strands for the negative terminal and the positive terminal are used or 8 strands.

RJ11 - Registered Jack 11 - is used for the landline telephone. It is an international standard that is used to connect the landline telephone to the Telecommunications network.
RJ11 uses a 6-slot connector. In it RJ11 has 6 slots (positions) and two conductors, the standard is written 6P2C. The information transmitted on the line can be digital (DSL) or analog. The telephone cable that arrives at the subscriber h
and RJ14 are both "recorded takes". This is what the "RJ" means in their names.

In 1976, the U.S. Federal Communications Commission asked Bell Systems to define a series of commonly used telephone connectors. These new telephone jacks were published as recorded sockets, with each swap having a separate identification number.

Bell published these standards as Universal Service Order Codes, or USOCs. These codes are in common use to this day and define all possible socket configurations for use with the telephone system. The RJ designation actually applies to the wiring plane of the plug and outlet, not to the physical form of the connector. A number of recorded takes share the same take, sometimes with very slight variations.
