When you say "telephone switch", what do you mean? Can you add some pictures of the closet setup and wall plate? Can you add a photo of the inside of one wall plate, showing the wires and the rear of the jack?

And a second photo showing where the cables all come together, in a patch panel probably. Note this is very similar to diy. Also diy. Pictures would really help this question. Add a comment.

While it is possible to get plugs for this, the normal best-practice is to terminate the solid core wiring on a patch panel, something like this : And then to run short stranded patch cords into your switch or router.

This is all a bit generic, but we can be more specific as you provide more details. Improve this answer. Criggie Criggie 5, 16 16 silver badges 40 40 bronze badges. Ecnerwal you are correct - sorry I mixed up this and a similar question where the in-wall wires were cat6 — Criggie. Basically you have the brown pair incorrect on your pinout diagram. The two wires in the brown pair need to be swapped around for your diagram to be correct.

Can you show how to make an rj11 male plug on one end to an rj45 male or female plug on the other end I've seen a cable adapter like this but it is'nt sold in our country. The idea behind this, is that i'd like to have my connection direct from the internet drop off box and not passing through the main modem which serves as the distributor.

The problem with the modem set up is, when the modem is turned off, all internet connections are also cut off and sometimes we need to wait for the main office to open before we can use the internet because that is where the main modem is. Thanks in advance if you can show my request Old post but for anyone that still views this never use an extender for your DSL or fttn internet get a longer cable that is all one piece with both male hook ups on the end, another word of advice keep it under 75 feet try to go max of 50 feet if you can on the wire as longer then 75 feet but not always could start to do it after 50 feet can lead to connection drop out from Jack in the wall to the modem due to how long it takes to communicate and another factor frequency of devices that the line picks up from other devices around it, ethernet is the same as rj11 and what happens to the 11 above happens to ethernet as well.

Your comment about the line numbers for TB is incorrect. Imagine your diagram of TB, with the green and brown pairs physically removed. Now plug in a 4C phone cord, and you will have only Line 1 working. Electrons are color blind! They are still electrically wired identically.

How do i extend and use the main wire to an existing electrical outlet so that i can run the single wire thorough the house to other electrical boxes keeping a single wire run to extend each box to another box? I need to be able to tap off each box on the single run wire. What is the best method so i do not have to have a gang of wires for my rj45 cat5 wiring? I got way too clever and tried to punch the other ends down to a 66 block.

I am stuck and in a hole because I've done this six times throughout the home. At the 66 block, I tried b order not A because that's what we always use and got nothing really.

I tried blues, oranges, greens, browns-common order and got nothing also. Can you save me here and tell me the order the wires should be on the 66 block? Your diagram with the cables being split into line 1 and 2 then line 3 and 4, this goes from the inside out. On the sutter connector, this isn't the case on the right hand side of their diagram. I followed your tutorials and had to remake all my ends to match their connector. Just an FYI.

Minor gripe but truly I am so grateful and thankful for your tutorials. The pug end is just going to be a standard 8p8c modular plug and the order of the wires is going to depend on the wiring standard used for your structured wiring.

How the wall jack was wired. For TIAA it will be white green, green, white orange, blue, white blue, orange, white brown, brown. If you're using TIAB it will be white orange, orange, white green, blue, white blue, green, white brown, brown. I have a two line phone jack and I want to hook up two different cordless phones can I use the Breakout wiring into another Jack using the inner pins or the outer pins? TB is the superior choice because it matches the Ethernet standard.

Now the jack is versatile. I have a fiber in my study room and the other fiber modem came with RJ11 port for cordphone..

I would like to have a phone in living room. Hi Great site and info I want to continue my phone cable with Cat 6 cable The colours of my phone cable are red blue black and white Which cat 6 wires do I use to connect to the phone cable please. Hi Can anyone help? Thank you! This article represents my own opinion and may contain affiliate links.

Please read my disclosures for more information. Before we get into separating the phone lines, lets understand what's going on in the jack. Nobody uses the old quad green, red, black, yellow phone cable anymore in new wiring. It's mainly Cat3 or better cable which consists of 4 twisted pairs of wire in blue, orange, green and brown along with their white wire that has a colored stripe white-blue, white-orange, white-green, white-brown. Since a standard telephone only needs one pair of wires per line, we can send up to 4 lines on each cable.

This offers a lot of flexibility and saves time and labor running phone cables in a multi-line system. Even if you're only going to be running a single phone line, you have room for expansion.

Wouldn't the socket be damaged if we accidentally misalign the RJ to it? MathewC MathewC 6, 8 8 gold badges 37 37 silver badges 53 53 bronze badges. Yes, you could do this. You can wire RJ to handle RJ signals. Joel Coel Joel Coel That's what we do - network and phones are both RJ, both use the same structured ha!

Yes, can you physically plug an RJ11 jack into an RJ45 socket, as you have seen before. Russell Heilling Russell Heilling 2, 19 19 silver badges 21 21 bronze badges.
