What is difference between RJ11 & RJ12? -- package that I have for a 6 connector modular plug says it works with RJ11/RJ14 but it is 25ft -- too long for what I need. Will this RJ12 7ft work?
Asked by: BR
RJ11 generally has six positions and four connections (6P4C) in the connector and is mainly used for phone communications. RJ12 usually has six positions and six connectors (6P6C) and is generally used for specialized phone systems. Please verify the wiring and requirements of the equipment you are connecting.
