When does function order matter?

Hooking up an rj11 modular phone plug to a phone cord... does it matter what order..?

• Does it matter what order the red, yellow, green, and blue/blk wire goes INTO the plug before I crimp it? If I hard wire the connection, it sounds fine and everything works. But whenever I put the plug on it, it just makes a loud buzz. Some of them do it and others dont. So all I can think is that when I push the plug on, the wires are hooking on in an incorrect order in the plug. Is that it? Does it matter? Any tips? If it helps, these are old 500 model phones Im trying to get plugs on.

• Answer:

  It only matters in the way the conductors lie in the cable and what the other end looks like. They get reversed when you put a modular plug on each end, but when you go to "quarter mod" it gets tricky. I pulled a quarter mod cable from the shelf and it goes tab down black/red/green/yellow. When we make up base cords for full mod, they go "tab down black to the left" on one end, and "tab down black to the right" on the other. On the inside of the phone, you will probably need to move the black ringer wire to the green line terminal (be it L1 or L2) to make the ringer work. The yellow and green wire got tied together in a non-modular phone plug.
