My house had an extra line added for a data line. I decided to add a extension in another room. At the junction box, the R&G wires were connected to the B&Y terminals for the second line. I took the B&Y wires from the first line and connected to the B&Y terminals at the junction box. The second line works, but I have a lot of noise on the first line and poor quality. What would cause that? Can wires overlapping cause that?

I'm having a little trouble understanding what you did exactly, but no matter. With a two-line setup I would recommend that you run both lines to all outlets connecting line 1 to the red and green posts, and connecting line 2 to the black and yellow posts. This gives you easy access to both lines at all your phone jacks. You can puchase phone line splitters that plug into the jacks wired as I describe that separate out L1, L2, and L1+L2. Some telephones are even wired to directly use both lines when wired this way.
Now, as to the noise problem. Several things can cause that. Moisture in the wiring, corroded or loose connections, some sort of ground loop, it could even be on the phone company's side. You should always go directly to the network interface box and plug in a known good phone. If you still have the problem there, then it's the phone company's worry. If not, carefully check all your wiring and connections. Depending on how things have been wired you can disconnect jacks one at a time till you isolate the problem. Good luck.

hello rpp,
there r alot of reasions that noise can be produced on a phone line.the most common causes are moisture, bad connections, wrong type of wire, miss wired, cross talk. in my experence unless u r running cat 5 cabel u will get noise on the phone line whin running it with a data line. my sugestion is this from the interfase box run a new line to the new jack and wire it to the operate terminal in the interfase box (ie line 1 or line 2) it only takes 2 wires for a phone line and the standard is red/green line 1 black/yellow line 2, this is for standard 4 wire phone line. whin u wire the new jack connect only the red/green to operate terminals and wrap the black/yellow around the cabel, this will more then likley cure your noise problem.
