RJ12 uses all six locations while RJ11 uses only four. RJ12 RJ12 - Registered Jack 12 - is a standard of the same family as RJ11 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. , 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 RJ11 RJ11 - Registered Jack 11 - is used for the landline telephone.

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. is aimed at individuals. The terms Tip and Ring are used to refer to the beginnings of telephony when long audio sockets connected the customer's line. The translation is 'point' and 'ring', they correspond to the 2 conductors needed for the operation of a line. The voltage in a subscriber is usually 48V between drivers Ring And Tip With Tip near the mass and Ring -48 V. Copper conductors therefore go by 2 in all RJ sockets and have distinct colors.
