Unusual telephone installation problem - Help

[sidw]

I have two phone lines, identified as Line 1 and Line 2. Line 1 is the main house line; Line 2 is a "hunter" line: if Line 1 is in use, any incoming call will automatically jump to Line 2. My installation requires two separate jacks since Line 1 also accommodates my answering machine. I use the red & green wires for Line 1, black & yellow for Line 2.

Problem: I had to remove both jacks from the wall and disconnect all wiring in order to re-do the room (sheetrock, etc.) and don't recall which wires were connected to which terminals on which jack to duplicate the above installation. I did make a schematic before disconnecting but it got lost in the shuffle of reconstruction.

Can anyone out there with knowledge of telephone wiring help me? Thanks a bunch.

The jack terminals should have matching coloured wires or lettering molded into the jack.

If not, try Googling for RJ11 wiring.

If the jack is not color coded, the middle 2 pins of the RJ is line 1 and the outer 2 pins are for line 2. Not sure if polarity is an issue. By the way, why do you have a seperate "jump" line? Can't you just get call waiting?

Line 1 Green = Tip; Red = Ring Line 2 Black = Tip; Yellow = Ring

SO: On jack for line 1: Green Wire to Green on Jack; Red wire to Red on Jack. On jack for line 2: Black Wire to Green on Jack; Yellow wire to Red on Jack.
