House Phone Line Wiring

hey there welcome back to do-it-yourself telecom where I cover telecom related topics explained for the non professionals and those aspiring to be professionals we're going to cover household wiring right here so in residential environments the wiring for telephones is a little bit different than it is for commercial environments sometimes it can be the same but oftentimes it's a little different as I'm going to show you both styles and so you can know how to either add or repair or troubleshoot a telephone jack let's talk about two different types of wires you might have and let's talk about the three different types of Jack's you might have so the two different types of wire you're going to encounter is either going to be the commercial for pair what they call UTP unshielded twisted-pair the way you'll know that is you'll see you'll see four sets of wires twisted together but they call those pair and they'll have four different colors blue orange green brown the other cut you're going to run into and this is more common in private residential like in homes especially homes built like in the 60s 70s 80s and I guess even in the 90s is the the four wire what they called rock wire or two pair drop wire it's typically a tan jacket with four wires inside and those wires are red green black and yellow you may even see some of this with a few other colors like a blue and a white the key to doing residential wiring for single line telephones is just to keep the colors matched up we're get into that just a minute for three different types of jacks you're going to encounter are what they call flush mount meaning that it flushed with the wall obviously not those wires beside like that okay the other one you're going to see is what they call surface so it sits on the wall or it sits on a baseboard but it doesn't it's not flush with the wall in the industry this is oftentimes referred to as a biscuit jack because it kinda looks like a biscuit and then another one you're probably going to encounter or may encounter is the the wall mount Jack which is different from this kind of jack a wall mount jack is designed to hold a phone on the wall so it actually mounts on the outside of the wall or on some kind of surface and these little tabs right here they hold the telephone so you take the phone you put it on slide it down and it connects right there you know you saw those like in you know your kitchens grown-up or maybe in your grandma's house you don't see them quite so much anymore but that's wall mount all right and within those two different styles of connecting the insides are screw post and then 110 or modular all right I'll talk about those in a minute now all the wiring that delivers the telephone line into your house begins at what's known as a D mark and I'm going to cut over for a second for a quick little video talking about the D mark because you need to understand that that's where your service begins okay so this is the telephone D mark on the outside of my house right here a few clues that kind of give it away or you'll see a phrase like network interface you might see something about customer access got something here that says AT&T yours might say Southwestern Bell southern New England telephone frontier anyway the point is is that you locate this box whether it be on the outside of your building or might be on the inside and you know in some cases with apartments you may not even have one but this is the point where the phone company brings in their service either from underground or off the pole or off the street goes into here and then all the wire that goes beyond here goes into your house is is your inside wiring all right so that is what a Demark is okay so now that you understand the d mark and let's say we've got some wires here and we know that these are coming from the d mark and what we do is we want to take and match the colors so on a screw post you got red green yellow black you just match the colors red green yellow white that's all you got to do is just match the colors now typically a single line telephone in residential environments only runs on what's known as one pair a tip and a ring tip and Reema that's just telephony speak for the green and the red tip and a ring that's all you really need to worry about is those two wires however if it everything is already wired in for wire you might as well go ahead and keep it that way also you have a second line in your residence then that might be on the black and the yellow and by the way the black is tip in the yellow is ring if you have commercial wiring then the tip and ring for your single line is just going to be on the blue pair so the wire that's more white than blue we call that the white blue wire is the tip and the darker the dark blue or solid blue or one that's more blue than white is known as is the ring the way those match up is if the green is the tip then you match the the white blue to the green and you match the solid blue to the red okay so and you won't see screw post Jack's with with with the white blue blue you might see with modular but you won't see it with the screw post so the other thing you can run into is the the wiring from the Demark might either be in a star pattern meaning that there's a home run so I mean the wire is individually run from the jack straight back to the D mark and that's true for every Jack in your house but oftentimes especially in older construction the wire is serialized meaning that it goes from the d mark to a jack like this okay let's imagine that this was all screwed down and then another wire will go from here double double terminated meaning you've got two sets tied down on the same screw post then it goes to another jack so when you're troubleshooting if you've got a jack that's not working it's possible that you may need to go to another Jack of the house and find out if maybe the wires have become corroded or disconnected because it might be that say for instance the jack in your kitchen is not working because the the spot where say maybe let's say for instance in the bedroom where the second pair of wire has like come on you know either corroded or come apart or falling off or something like that all right so if you do have serialized wiring the way you'll know is use you'll see you'll see two two wires like this you'll see one coming in and one going back out and and so if you troubleshooting a problem with no dial tone on a jack in one part of your house it possible it is because the wires come apart in another part of the house like at another jack other than the screw post okay so I showed you screw post you'll see screw posts like on a on a you know on a biscuit style you'll see it on the the wall mount style see it's got the screw post right here you can see the colors where they go on the back and then also you can have it on a on a flush mount where you've actually got the post right in the back now this jack is a modular jack the reason they call it modular is because it literally is a module that connects into a blank faceplate alright so there's your bitch'll modular jack and then there's your faceplate and you could have these with one two three four even as much as six of these little holes where you can put you know different jacks in there all you're concerned about is getting the red in the green into the tip it ringspot on this Jack and I'm going to tell you what that is the tip is little spot see these little color code where you see a little spot marked with a blue and a white and the ring or the red needs to go in the solid blue all right now don't get fooled there is a green there but you don't want to put this green on there you want to put the red on the blue you want to put the green on the white blue if you have what's known as a punch tool you can take and you can lay these wires inside the little slots a little bitty slots in there you put the wires and the slots like that and then what you do is you take the punch tool and you and you you you hard to explain but the punch tool pushes down on that wire in such a way that it pushes in there and it cuts the excess wire off and then when you're done you put the cap on if you don't have a punch to what most you know people who don't do this all the time don't have a punch tool you could take those wires and push them in as much as you can with your fingernails like that and then you can take the cap and you can put the cap on like that you can think it's our pliers and you can cinch down on that cap and what that will do is it will push that it'll push that wire down in where it needs to go then you're done just take a pair of well these are called snips but they look like scissors and then you you just cut those up these are special Telekom scissors they're called 'step so you can get it at the big box warehouse stores or i've got a link in the description where you can get these if you're interested so the problem with the modular stuff is it doesn't lend itself well to the serial thing because you can't massive hose you could but it doesn't work well you can't have a set of wires coming in and a set of wires going back out to go the next jack this is more used for commercial environments typically what you see in most residences is the screw terminal types alright so I hope that helps you with your problems or new installations if you are installing a brand new phone jack and you want to know how to do this trick with the in the drywall you get these things are called caddy clips there's probably a generic name for the name that makes them again big-box store or you know online and what you do is you you find a spot and take like a pencil and just you know make a little outline and then you cut just a little bit outside the pencil line and then when you're done you you know get rid of that sheetrock this in the middle and then you you put this thing in here I'll take it out the package you put this thing in and then what happens is these little ears right here they fold out like that and they go in the wall and then you bend the ears back and what happens is they come with little screws that you use to go into the drywall and then it comes to the other side it bites onto that little ear on the back and it holds it it gives you that what they call like a mud ring for the for you to mount the surface mount jack on okay hey please leave me some comments let me know if that helped or something else that isn't clear maybe I can redo the video or give you another one I appreciate your viewership and thanks for watching
