RJ-11 Plug Wiring

RJ11
This is the wiring for the plug side of an RJ-11 connector. Can you say "BRGY"? (Think about cheap red wine; I know I do.) The diagram is shown with the "hook" - the little thing you press on to get the plug out - underneath. RJ-11 sockets always have the colors indicated on the terminals.

 Note that the connector on the other end of an RJ-11 connector is wired in reverse order. That is, if you stretch the cable out flat, the Black wire stays on the left all the way to the other end, including through the connector with the hook oriented down also. Also note that the RJ-11 connector has six terminals on it. Only the middle 4 are normally used. Line 1 is the center pair: red and green, as in Christmas.

 

 

RJ-11 Connecting Lines on One Jack

RJ11 One Jack
One Jack Connecting your jacks in this manner may allow use of existing jacks. You may even find that your jacks are already connected in this manner. However, you should check to ensure that the black and yellow pair is connected for line two. I'll show the connections for screw terminal jacks. This is the most simple connection. To connect both lines on one jack, simply connect the wires from your cable to the matching screw terminal. To use line two with a single phone or other single line device on a jack wired in this manner, you'll need to use an A/B Splitter Adapter.
