Wiring in a DSL filter

I need to wire a DSL filter with a modular jack and plug into a phone line without a modular jack/plug. I figured I'd cut the plug off the DSL filter and wire those into the phone line. However, the colors of the wires in the DSL filter are black, red, green, and yellow and I think the phone line is in pairs with different colors.

How should this be wired in to the phone line?

Is there a better way to do it? (I went by Radio Shack and they didn't have any modular jacks and plugs designed to be wired in this way.)

Does the phone line end in the old 4 prong outlet? Yes? Buy a converter. No Google how phone lines work. Most old lines only use two wires for signals. Other two are not used or are for power to the lights on old phones.

These days red/green are your primary pair. Black/yellow is the second line pair. Green is positive but odds are polarity won't matter.

I would do it differently, but to answer your question.

Red and green are the primary phone lines. Your existing line has 2 wires. Connect one to red and one to green. If the phone rings AND you can call out everything is fine. If not switch the two wires.

Reason: most newer phones can handle reversed polarity, some older phones can not.

No old 4-prong. It is a new phone but it is hard-wired in. If I know which pair of wires is used, should they go through the red and black wires of the filter, or some other pair?

As per the other replies..... telephone color coding for the last 40+ years

red & green .......line 1 black & yellow ......line 2

my last wired phine work ~2005 polarity did matter, so if you try red & green one way and oyur phone doenst work; swap them

sounds to me like the DSL filter is set up to service two lines

Here's a good link that can describe it better than I can:

What is a better way?

What I have done is cut the modular plug off the filter and stripped the red and green wires. Then I took a wall-to-phone cord (I have plenty of those) and cut off a plug with a few inches of wire. I tried to strip the red and green wires but they are so tiny I can't strip them.

My plan was to plug the plug into the filter jack, then I could put that inline in the phone cable.

My wire stripper goes down to 22 gauge, but it is smaller than that. The insulation is tough and the wires are tiny so I haven't been able to do it with a knife without breaking the wires.

What I chose to do was split the incoming phone line at the entry point to the basement. Using a system of modern modular jacks I ran the unfiltered source to the modem and used one DSL filter for the rest of the house.

Next person can filter that line if they want to simply by adding another filter.

As for your striping problem a match or lighter works well for burning the insulation off the wires which can then be trimmed if you burn to much.

Now you know why the "better" way involves dealing with the access lines, not the equipment wires.

I haven't seen a new hard-wired single-line phone in 20 years. Is there maybe a sliding or rotating cover on the wall outlet that is covering up the plug on the end of the cord? Post a picture of this phone and the wall plate someplace, with a link back here, please. A picture is worth

1000 words, etc. And even assuming the wall end is hard-wired, is the end on the phone detachable? You can always use a double-ended rj11 block (used to hook 2 wall cords together) to connect the DSL filter in-line, and plug the short cord into that.

BTW, forget radio shack. Their selection has purely gone to hell last few years. Try Lowes, HD, Menards, or similar. The parts you need are out there, at cheaper prices than RS. Too bad you aren't local. I'm 99% certain I could solve your problem out of my junk box.

I tried HD also, no luck. We also have Lowes.

Hi, Don't cut the wire. Un-hardwie your phone. Install jack plate for the phone and filter.

Agreed

That is probably more involved than I can do, but it sounds best. I'll have to get someone to do it.

That left each with with two tiny conductors, each about the size of a thread. Probably too small to attach to the wire.

I think I know who can mount a wall jack for me without charging electrician/phone company rates.

It can be a surface mounted connector. Easier that what you are trying to do in the first place. Much easier if you have to replace anything down the line.
