Trim off the portion of cut sheathing, using the cutters on the strippers or using cutting pliers. Untwist the individual wires inside the cable from one another. In many cases, you'll need to strip only two of the wires if you are installing a standard one-line residential phone line.
A second pair of wires is used if you are installing a second line, such as a second voice-phone line. Then, identify the individual wires you'll be using:. Old four-wire cable:. Cat-3 or Cat-5 cable:. Remove the cover from the front of the phone jack, exposing the mounting plate and mounting screw holes. If the phone cable has been run inside the wall, thread it through the opening in the plate as you position the plate against the wall over the access hole. If the phone cable is surface-mounted, such as onto the front of a baseboard, the cable typically is inserted through a notch in the side of the phone jack.
Mount the plate to the wall, molding, or other structure, using a screwdriver and small wood screws or drywall screws. Some phone jacks may have self-adhesive strips for securing the plate to the wall, but if this type of jack also has screw openings, it is a good idea to reinforce the installation with screws. Connect the stripped wires from the phone cable to the corresponding screw terminals on the jack, using the following color combinations each jack terminal is identified by the color of the wire that is preattached to it :.
To make the wire connections, loosen each terminal screw with a screwdriver. Wrap the bare copper end of the wire around the screw in a clockwise direction, using needle-nose pliers.
Tighten the screw to secure the wire. The wire insulation should just touch the screw terminal and there should be no excess bare wire extending out from the screw. Reinstall the cover onto the jack's mounting plate. Some covers are secured with a screw; others simply snap into place. Plug a phone into the jack to make sure the line is working properly.
Actively scan device characteristics for identification. Use precise geolocation data. Please help, Thanks. I am wanting to add a phone jack to my living room, which does have one. It does have several electric plugs. Is there a way of coverting an electric plug to a phone jack?
I have a cable box on one side of the room that needs to have a phone line connected to it, but no phone jack close to it. Any help would be appreciated. My old house telephone wires are red, black, blue and white.. When I connect the black to black and red to red and cross the other two over, i still get nothing. John, you are so smart. I have an older home with all the different color-coded wires.
I had to install a newer wall jack because mine fell apart. I have been working on it all day trying to find the correct combination with no luck. I was about to give up when I found this website and saw your color code chart.
I took your advised and took the old Bell way and it works. Thanks for your import and your color code chart. I have a dual line telephone jack. The wires, from the wall, have detached.

I have an office that needs three phones. One one particular jack the jacks wiring looks good. The correct colors are matched to the correct place. But when i plug the cable into the PBX and then plug the phone into the jack I get nothing…any suggestions? HI, I wanted to move a jack which left two cables with a bunch of wires, now my phone has a buzz, so if i move the line may or may not clear up. I have no idea how to reatatch the wires to the jack.
There are two cables and they each have these color wires how do I hook them up? I have static and no dial tone on all jacks in the house. There is a dial tone at the NID. All other pairs in the line are good.
I have installed a second phone line into my garage,when i hook the line up in the main box outside it causes my dsl to blink out.
Can installing incorrectly cause any type of electrical issues? Could this be a fire hazard? I replaced the telephone jack in my kitchen and it works…but somehow I turned off all of the other phone jacks in the house. Any suggestions would be appreciated. I would like to install a new hidden phone jack in my closet, my closet is close to the outside phone box, what are the steps? I just moved a jack that the tv satellite box was plugged into.. It only required me to remove 2 wires..
When I hooked it back up, no dial tone. Other extensions in the house work. I stripped it back to a new spot and still no dial tone. What am I missing? ES, The wire is wrapped around the terminal in a clockwise direction so it pulls the wire tighter when you tighten up the terminal. Need some help. I have a spliter in my wall jack. I am attempting to install a dual wall jack to get rid of the spliter.
The other, with black, red, green white. I attempted to hook them up but got no phone signal. The wall jack only has four colors, red green balck yellow. I have a problem. I live in an old house and have installed phone jacks before. Now I have tapped into an existing jack at the end of the line and run two new jacks.
My problen is the 1st jack works but the 2nd jack does not work. I have switched the jacks and both work on jack 1 but neither work on jack 2. Hi Katlady, I would start by checking to be sure the colored wires you are using for each jack are connected to the interface box. We notice when one person is on line two you can hear the conversation through line one, it is muffled, some days it is louder than others.
The phones came with a phone line that was a blueish, green phone wire from jack to phone. Any suggestions? We need a working phone line to order movies from the DISH. Any ideas or do I need to call in a phone service person to check this line out.
My phone jack has 7 wires and the wire coming out of the wall at a cable box has 7 wires. What do I need to do to make this phone work at new location? My closest jack to this is wired to a 7 wire jack. Danny, I live in Michigan and have my phone wire coming in from a pole. I noticed that when I looked under the cover that only the 2 brown wires were hooked up, there are other wires which used to be hooked up an are now cut off.
My phone still works in fact I used to think maybe my phone was tapped because I could here dogs barking and other noises. Should the other wires be hooked up? Our line coming into the jack has six wires: red, black, green, blue, white and yellow. Exactly which wires go to which four screws at the back of the jack?
It has red, green, black and yellow. Your other option is to see if you can trace the wires from the jacks in question back to the interface box mounted on the outside of your house. Next, open the cover on the user side, determine which colored wires were hooked up in the interface box, then use the same colors on the jacks. Option three would be to use trial and error and check each of the wires at the jacks until you find the combination that works.
I have netzero dialup, and i have a long 50ft phone wire running from downstairs, to the upstairs. My kids were running through the dining room, where the wire cuts across the floor, and they tripped over the wire, and yanked the wires out of the phone jack. There are four color wires sticking out of the wall.
Black,yellow,green,and red. I dont know where to tie the wires on the phone jack. Same color as the wires that were ripped out. But like i said, i dont know where each wire goes.
And without the jack, no internet. Can someone please help me? Hi Drew, You should be able to match the colored wires up to the same colored terminals. I matched up the colors, and all i get is like a humming sound from the phone. Not on any sides of my house, or even in my basment. Drew, Unless you are getting your phone service through the cable company, there should be a phone connection box somewhere.
If you have underground utilities, they will come out somewhere, either on the wall outside your house or the basement, or a wall or utility closet inside. If you can dial the phone but it has a hum, check out our article on How to Fix a Hum in a Phone Line.
Thanks for the help. Im still kind of confused about all this, but i just hired someone to fix it. Thanks again. Last week ADT installed a security system and connected their monitoring box to the phone NID with a new cable of their own. But while trying to figure out how to install their system, the ADT installer removed a two line phone jack in a nearby room , fiddled with it and then put it back in the wall.
After he installed the system, I noticed that we had fax but no voice service. When I dial the voice number from my cell, I get a busy signal. Thanks for your help, John. I forgot to mention that when you try to call out with the voice line, you get a busy signal.
I do not have a phone line we use cell phones however I do have DSL modem. I changed the location of my computer last night not realizing that the phone jack had to be wired different for the DSL.
I took it apart tried to wire it like the other jack but they are totally different jacks. I have a jack like the picture above with the 4 screws. I belive the 2 blue wires are the ones that I use for DSL but which ones, there are 2 sets coming out of the wall and where do they go? Anyone have directions…with pictures? Hi Amy, First check to be sure the jack in question is hooked up at the interface box to the line that has the DSL, then use the same color wires that are connected in the interface box for the phone jack.
Hi great site you have here! Here is what i am dealing with. I just had my phone service turned on today. Only 1 of the 3 phone jacks gives a dial tone to my phone when i plug the phone cord into the phone jack. All the wires in the three phone jacks are connected.
Would my rechargable phone make a difference in this case? Two of the three phone jacks appear to be a bit older than the type that gives a dial tone wall mount type with spring retractable half moon looking swivel door I know this could be a it might be this,this or this or that question.
What other checks might be effectively applicable in sorting this no dial tone thing out? Thanks to the phone pros and non pros alike! You might take the cover of the jack and be sure the wires are hooked up to it, then check the interface box outside to be sure the same color wires are hooked up there as well.
If all appears wired properly, my next step would be to try hooking up a new jack to the existing wires. If still no go, try swapping off the existing wires at both the box and jack. Last resort would be to run a new cable from the box. I have a newer home, about five years old or so I think it has the six wire interface box since I have three separate phone lines.
I just bought a Polycom phone which is an analog speaker phone only for my office. I also tried a 6-line splitter to the wall but nothing. My Vtech has an ext. Thanks for this great service. John C. My jacks are the usual red, green, yellow, black, etc. My cable appears to have a solid color next to the same color with white hashes.
So, which one goes to red or green? The solid, or the one with the white hash? I sure hope somebody can help me with this. I just ran a new phone jack into the living room for DSL to our computer. There are now 3 jacks in the house bedroom, kitchen, and living room. The kitchen and living room are next to each other, but the jacks do not share a common wall.
The bedroom phone jack always works. I cannot have anything plugged into the kitchen and living room jacks at the same time because neither will work. Only 1 can be plugged in at a time between those 2 rooms. To further complicate the matter, the phone jack in the living room will randomly dump the DSL signal and will not pick it back up until I pull the jack out and let it hang from the wall.
I have replaced the living room phone jack once, and it worked for a week, but now it quits again. Any assistance would be greatly appreciated. Thank you! I have a question, I just recently signed up for verizon dsl services and they told me that in order for my dsl services to work I would need to install a new jack in my room or re wire the one I already have so that the number I have already will not work on it.
I would like to know how would I go about doing that? I recently signed up for verizon dsl and I need to install a Seperate phone jack so I could use it because its on an seperate account with the phone line. Hi, 1 What does it cost ballpark figure to run a new cable from the NID through the house for 3 jacks?
I was removing wallpaper in the kitchen and had to unscrew the plate cover that has the phone jack in it and the thing you screw the satelling cord to. When I was scraping the wallpaper, I must have touched the wires with my arm somehow and got a slight shock.
Since then, none of our phones will work in the house. I went outside and checked to see if we had service coming into our house and we do.
Any ideas on what could be wrong? While you could figure it out by trial and error until you find the combination that works, a better idea is to open up the interface box, find the line that goes to your jack, note the color of the wires that are connected to it, and match those same colors on the jack. I recently moved into someone elses home, the bedroom that I use has no phone jack and I am wondering how to approach this problem.
One phone jack is located in the bedroom next to mine. The phone jack is on the wall in the other room and that wall is the same wall that I have too. So I use a pin light; shine it from the wall jack, it would go maybe 1 foot through the wall to my wall which looks like its the same wall as his wall is and I could take a drill and drill right through my wall and it would open up and I could unattach his wall jack and attach it to a new wall jack in my room. I am asking you if this is what I would need to do?
I did look in my closet but asside from this big insulated 12 inch diam. Great site! I have an old telephone wall mounted jack. There are 2 wires going into it, each separating into yellow, red, green and black. There are 8 screws available to attach these to—4 on each side of the jack.
I have tried connecting the other green with the green still attached to the second screw on the right, but no dial tone. What should I try? I have a connection in my basement, that has two studs with nuts on left side, and two studs with nuts on the right side.
Thgre is a main cable coming in from the box outside, with a black and white wire. I can send a picture, if that would help. Cat 5e is available with each pair shielded as well as the whole cable shielded. For average residential telephone installations shielded phone cable is not usually necessary.
I recently purchased a Leviton Decora style telephone jack and the above phone jack wiring diagram was included in the package. Below is a diagram for four pair wire on a plug and jack. Notice that the blue pair is in the center. You can plug a standard two pair phone plug into this jack for standard phone service. I recall having one of my regular clients get me over to check their phone wiring after a telephone repair person told them that they had voltage on their phone wires.
I knew exactly what was causing the voltage on the phone wires. It was the above mentioned long forgotten transformer. The original purpose of that transformer was to provide power to a Princess Telephone which had a dial that lit up. Those phones are no longer around, but many of their small gray or beige power supply transformers still are.
If you see one in your house, just unplug it. However several times when I have been in clients homes I got asked to install one or more telephone jacks. So I bought myself a telephone wire punch down tool and a tone tracer to identify the correct pair of wires.
The telephone tone tracer is fabulous for tracing telephone wires , but it does not work as well on complicated electrical circuit wiring. There are other electrical circuit wire tracers available especially for electrical circuit wiring.
