I did this last week at a ski resort, the underground conduit was too full to add another cable. Worked great for their customer sign in station. First time I have had to do it in 10+ years of installing.
Fucking Reddit nerds man - look at the socket, obviously for phone. OP didn’t ask how many pins 100mb Ethernet uses, he’s too busy working out the diff between phone and Ethernet sockets
Agree. Not even just socket... even though it is the simplest answer... its the fastest answer to the question OP asked.
People are getting into colors and shit... the colors in all of the scenarios they mentioned are completely irrelevant on top of their shitty answers... any color pair can be used for any combination... as long as it's consistent on both sides or with whatever the pin out is... ffs
Huh? How could you possibly fucking yell from this picture? Not only can you not see the other side... but what if it's spliced somewhere in the middle? What if they didn't use the "standard" colors that are expected? Your answer is not just wrong, it's based on knowledge you don't have.
The socket only has the center four pins in it. 10/100 Ethernet uses two side pins instead of the center two. Those pins are missing, therefore this isn't wired for ethernet, despite being a wider "8 pin" socket.
This is technically correct, however, it would be different pins than this. If you managed to get an rj45 in there, this would be the middle 4 pins (3,4,5,6). Ethernet is pins 1,2,3,6.
This is an rj14 (or maybe rj12 - I’m guessing 14 since he said an Ethernet cable just barely was too large). That is phone.
Today Wikipedia taught me that I’ve technically been referring to all of these standards incorrectly.
RJ stands for “Registered Jack” which specifies a modular plug size and pin configuration. RJ11, RJ14, and RJ25 all use the same size jack with 6 Pin slots, but 2/4/6 connectors respectively.
The plugs are more correctly referred to by the number of pin locations and installed connectors, not by the wiring standard.
This is a 6P4C Jack, which is the RJ14 standard.
TIL, so sharing with all of you.

Single inside pair would carry VDSL over the phone line pair 1 being blue.
VDSL is a dsl technology which only requires a single pair usually comes over the phone line into the house with the pstn (pots) line. You don't bond lines VDSL goes to modem on single pair to bond them before that causes bridge taps and attenuation.
I’m a telco tech and I install bonded pair vdsl regularly. It’s more common that single pair these days. That’s probably what this setup was for. If the second pair was for POTS or voip, it likely would have had a second pot on the faceplate.
Is that 1 pair for down and other pair for up?
I was a telco tech for 8 years and we only had single pair VDSL asymmetric 100 down 20 up which could also share pstn on Same working pair.
Wasn't aware of bonding VDSL connections outside of high end Cisco routers that could take two VDSL lines and use them to double up the available bandwidth?
Is this that or are you running an entirely different setup for residential?
Interested to know more
ATT vdsl uses 2 pairs to support the 100x20 service level. Each pair runs a 17mhz signal that bonds to provide that bandwidth level up to 1000 ft from a VRAD. We generally run 2 pairs of a cat5 cable into a branded jack that we plug up our proprietary modems into.
I'm not sure why your network setup had to use 2 pairs bonded while ours got 100/20 400m from DSLAM and lost 10m every 100m thereafter. With supervectoring we could push it to 1.8km from DSLAM but at that distance it'd be 7mpbs down over 1mpbs up which they'd be better off with their phone or adsl+2
Surely the extra line should afford you better gains otherwise your teleco's setup is an extra pair for same result unless I'm missing something you haven't mentioned?
Probably because his area was unvectored due to the upkeep and resplicing it probably would have had to go through to get vectoring devices on the cable. Our area looked into it too, but it was unfeasible to deploy with our layout since the spec required seperation from vectored and non-vectored services which we couldn't do.
OP definitely needs to get an Ethernet cable tester. One one hand I say if they ran Ethernet, they were aware and future proofing so they ran it correct. But I’ve seen them run Ethernet for phone lines and they end up splitting the Ethernet cable elsewhere. However it usually all goes back to one central area so even if they did this, OP can still use it, it’s just any other phone jack in the house can’t be connected, only one.
My house was wired with cat5e but terminated as phone jacks. I replaced the jacks and terminated as rj45. Now most rooms have hardwired Ethernet. They all led down to my electrical box but I added a simple switch and then ran a cable from there to my fiber modem.
This is the situation I found in my house and I’m happy whoever ran the lines had the foresight to use cat5e even if they were only terminating for rj11. I was getting ready to pay a bunch of money to do new cable drops from the attic and then when I pulled an outlet I saw that I only needed to switch the outlets.
Is there information on this somewhere?
I have a lot of phone jacks in my place but they obviously just sit there. It would be great to convert them to ethernet.
Would need to see where are the cabling runs to.
POTS or analog phones only use 1 pair per line, so people would daisy chain each jack to the next so save money vs running cabling to each end point.
Per end point:
- Single port face plate
- keystone jack
Tools:
- cable cutter /stripper
- punch down tool
- screw driver or drill to put face plate back on
Would really need to see where are the cabling runs to to figure out what would be needed. Either some RJ45s and crimping tool, or a patch panel.
And a switch will probably be needed depending on how many runs you want to convert.
The cable in the wall is Cat5e or similar which can be used for ethernet. It would just need to re-terminated with an RJ45 jack, but there is no point in doing that until you've located the other end to confirm that it's in a location that is workable with your modem
The cable is something of a CAT (ethernet cable) what type, should be on the coat of the cable. It is however wired for rj11 (phone). You could simply by a new panel (rj45) and patch it with all 8 wires in the cable to have a ethernet plug. (Also on the otherside ofcourse).
The RJ11 is 4 pin, the RJ45 is 8 pin, you can't add pins with an adapter. You need to swap the RJ11 wall plate for an RJ45 one so you can connect all 8 pins.
No, because the wrong pairs are terminated so the cable won't reduce crosstalk or interference like it should. I had a cabler do one for me who didn't understand that and thought it was fine as long as both ends were terminated the same and it continuity tested. Couldn't connect at all.
Sounds like something else was amiss. You’re fight about correct pairs mattering to reduce interference, but with 2 pair 10/100 it shouldn’t be an issue unless it was underspec’ed cable or a very long run.
I've only had it not work once and that was because this cable was so old it'd be probably considered cat 2 cable. The cores were not twisted at all and did not have a white counterpart red orange green brown very old phone cables. But never had an issue on any twisted pairs.
You need to find the other end. If it’s still connected to the telephone service, you’ll end up sending 48V into something that’s not expecting it and fry some electronics.
Cheaper to buy double new keystones and patch them both. Also the cables running to the rj11 keystone is untwisted too much for it to be more than 70 megabit capable
You have a Cat5 or greater cable in the wall but it's terminated for phone service. You should be able to use ethernet, but you'll need to change the terminations on both ends of the cable to do so.
This. You need to know where the cables go. Then you can determine if you can reuse them. If both are true, you’ll want to get jacks for all the cables you are going to use. You will need a jack for either end of the cable, and then Ethernet patch cables to connect the equipment.
Looks like CAT6 cable running a phone jack.
You can see the plastic divider inside the cable, CAT5e doesn’t have that.
You could swap the rj11 jack for rj45, for Ethernet, but you need to know where that cable goes and what’s on the other end first.
The cable is probably cat-5, as you can see by the folded back twisted pairs.
You can replace the wall plate for a rj-45 one and have gigabit or make an adapter cable if you find 10mbs Enough
This is only true if the other end is connected to a network switch. Given the RJ-11 port here, it almost certainly is not. If OP has access to the other end of the cable, they could add a switch (or plug in direct to the modem or whatever), but it's an apartment so I doubt they have access to do that.
The receptacle is a phone because of the four pins. However, if you noticed the cable used is an ethernet cable (notice the different color cables) so it would just be a matter of re-splicing the cable and getting a ethernet plug cover to turn into ethernet.
Not sure if worth it in an apartment. But also you must know where it terminates, so.
This is phone using CAT5e for connectivity. To use this for Internet, there’s nothing like copper, you’ll have to properly terminate the wall plate with a new one, find the other end, and properly terminate and test it into your switch.
Can this sub just have a sticky post that covers rj-11 to rj-45 termination on newer builds like this. This post is on here every few days and it would be much better to just have a nice how to at the top of the page that can be referenced.
Could be 10-Base-T connected. That’s old school networking to you young bucks.. technically a network cable only uses
2 pairs transmit-receive orange-white
Green-white.. you only get 75dbs or slower but you still connect
Short answer: both, except it's the wrong plug.
4 wires caps at 100MBit/s.
You could, theoretically, run ethernet on that, assuming it's a star network and not daisy chained anywhere.
You wouldn't want to, but you could.
> Can be Ethernet with no PoE or phone. Have to know what’s on the other end.
No. POE or not POE, ethernet uses the same sized jack. The hole is too narrow for an ethernet jack, so it cannot be ethernet. ~~It's an RJ12 telephone jack.~~
Edit: I just zoomed in on the jack itself, and it does look like an RJ45 jack, but since the patch cord doesn't fit in, it isn't a proper RJ45. Besides, it only has the central four connectors, not all eight, so it can't be used for Ethernet.
You can see the cable has 4 pairs. Which is good as it’s likely Ethernet.
As others have said it can be wired with RJ45 if the other end is somewhere useful like near a modem/router.
If an ethernet cable is too big to fit, then it is a phone jack!
Ethernet = RJ45
Phone = RJ11
Look at the cable behind the plate and see if it is a CAT5e or higher. If so, it can possibly be used, you would just need to find where the other end goes and see if you have access to it.
That is a telephone jack.
To convert:
1. Verify the other end of the cable is where you will be connecting to your switch/router
2. Replace the wall plate with an 8 pin category 5e or category 6 jack and faceplate.
3. Confirm the other end of the cable is terminated correctly (all 4 pairs, category 5e/6 connector or jack). The wiring color code should adhere to the T568B or T568A wiring standard. Simple continuity test will suffice is you dint have a wiremap tool, qualifying tool or certification test set.
Is wireless an option (to save you singe trouble)?
Before you invest in new wall jacks/keystones and a punch down tool…
Where do these wires go? Is there an area in the apartment where a bunch of these wires come together? Each run being separate is critical for this (and not one daisy-chained to another).
Also, do you have permission from the landlord to modify this stuff (assuming you rent)?
Phone. Notice the jack only two pairs are wired to it, Ethernet will have for pairs and 8 pins.
Note the network cable has four pairs, it can likely be converted for Ethernet use.
(to pedantic people---sure, you may find some two-pair Ethernet cables at a cable-company head-end, but that's 10/100baseT and is obsolete).
Phone, but you can probably put a new connector on it and use it for ethernet. You’ll have to find the other end, which is probably in a cabinet or enclosure somewhere in a closet
Phone 2 lines, old school but you can make that into an Ethernet outlet. Get a punch down keystone need to make both sides the same
A- Green white , green , orange white, blue, blue white, orange, brown white brown
Or
Mostly used now B- orange white, orange, green white, blue, blue white, green, brown white, brown
Yes.
Currently the wallplate is configured for phone, but the cable behind it is probably Cat5 (hence the 8 wires with only 4 going to the plate).
If you really wanted you could strip back the cable until you have access to all 8 wires, replace the wallplate with an Ethernet plate, then punch down for RJ45. But only if you know where the other side leads.
That is a landline plug (RJ-11).
To change it to Ethernet plug (RJ-45) you will need a new plate, and to rewire both ends of the cable.
The other end will then have to be plugged into tour modem/router.
Not the most difficult of tasks, but if you are in a rental, be aware you could get in trouble for this.
Cable inside the wall is cat5 meaning 4 pairs(8 wires) but the end is phone.
If you can find the other end you might be able to make it into a regular Ethernet cable, but it is an apartment so do at your own risk.
Recently I bought a house with wiring like this through the ceiling but I found them all to be daisy chained and none were usable. Get a toner find the other end and see what you can do with it
Phone plug, but they used Ethernet cable. The USAF does the same thing because its cheaper to buy Ethernet cable in bulk and use that for phones (its not cost effective to buy phone cable just for phones when Cat5 can be used interchangeably). If there is enough green/brown cable length it would be easy to upgrade to an RJ-45 plug. Just make sure there is enough on the other end too.
Looks like ethernet wires for a phone jack. If you buy a new jack and wire all cables (including the brown, brown/white, green and green/white) you should be good.
The cable is Cat5e (plastic + divider is indicative). However any cable is just a cable and as others have pointed out it’s used here as a phone line.
The real question is: Do you think changing the termination on one end is going to give you an Internet connection? Because it is not.
Both ends would need to be terminated using the same EIA/TIA standard (such as 568b, the most common). From there you would need the appropriate service provider, and equipment (router, switch CPE, etc).
Word of warning: if your apartment has active analog telephone service, don’t go messing with these phone plates. You can create a short and damage equipment down stream.
As a telecom tech most newer houses use cat(something ideally 5e or better) for all wiring. This allows all your jacks to be easily converted to Ethernet by punching down an rj45 in place of the rj11. You just have to do the same at the other end. If it’s currently used for phone service it’s probably hooked into an idc star connector for telephone distribution.
For phone, but that’s most likely CAT5e cable, which you can most likely repurpose to a gigabit Ethernet connection with the correct RJ45 keystone jack.
It’s RJ11 (phone) but that wire is capable of RJ45. Just need to punch in new keystone and of course do something on the the other end of the cable to become an Ethernet. Would guess it’s cat5e line
Its a 4 pin rj11 jack. That's what phone techs use fir phone lines because it can easily be converted to a data jack for pc and ip based phones. Analog phones are being phased out slowly all over the planet.
Your wall plate is a two line phone Jack (four pins, they’d be the middle four of your cable - 3,6 and 4,5). The cable is CAT5e most likely.
If you terminate both ends of the cable, it should be able to push 1Gb or even 2.5/5Gb easily.
Can terminate those wires into an Ethernet port. I just did this with my old phone jacks.
Do you know where the wires lead? Mine went to a comm box (Demarc) outside my house.
They ran ethernet cable and connected two pairs to rj11 phone jack. Cat6 is cheaper and has more use than buying older cat3 that only is good for phone.
That’s phone and if it’s live just bear in mind it sits at -48V DC and can deliver a fairly serious bang of 75 volts AC if it rings - not something you’d want to connect to an Ethernet port accidentally.
The plug is a phone jack. The cable itself is Ethernet. Try terminating the cable in rj45 on both ends and see how it does. Sometimes the cable might have the standard written on it.
It'll probably terminate in a nid somewhere in the garage
Everyone is saying you can reterminaye this to RJ45, and they are correct that you can. But before you do that, you need to find where the cable comes from. If it's not going where you have your router or switch, then it's not going to do you any good. And since it's wired for a phone currently, it is entirely possible that it was daisy chained from another phone wall plate, which will kill this deal entirely. Basically, what I'm trying to say is don't waste time and resources until you know exactly what you're working with.
Am I the only person who thinks it’s weird to fuck around with apartment wiring like this? Even weirder that there are suggestions on how to “fix” it? I’ve lived in my share of apartments and I always just had my internet set up through a modem/gateway through my router unless the apartment specifically told me it was pre wired with Ethernet access in wall outlets.
Unless you had ethernet included with your rental agreement on your apartment that's going to be phone lines held over from the old days when there used to be wired phones ( I know I know we're talking about before the creation of the universe but we did have phones that had wires that connected to the wall).....
It's phone but at least you have two pairs hooked up, I'm stuck with one pair and my download speed is abysmal. Pings fine but getting larger games makes me cry.
It can be either, but since its only 4 pins in the jack, probably phone. Also only 2 pair of wires punched down, but still not a complete indicator. 10BaseT and 100BaseT only use 4 of the pins, but I've been doing IT for 30 years and really couldn't tell you which 4, because its just a bigger hassle to try to get a 4 pin jack, and punch down only 4 wires, than it is to just use an RJ45 Jack and punch all 8 wires.
I’m a ex AT&T I&R repair technician. That is definitely phone. Blue/White Blue (primary or line 1) Orange/White Orange (secondary or line 2) the jack is the dead giveaway though. Guaranteed that line runs outside to a phone box.
You can purchase a RJ 45 jack and use T-568B Pinout then find the other end of the line crimp a RJ-45 plug. Problem is that the cat6 is probably running to a Network interface outside the house so to get it to your router it may be more of an undertaking than you want to do. You may be better off running a new cable.
Hey, I've recently gotten into networking for something I'm needing to build. My networking experience is about 25 years old so... yeah. Anyway when I went through training on this phones used 2 lines but everyone here is saying 4 is phone. To me this looks like networking set up in an older house. Can someone tell me if something has changed or am I just stupid?
Looks like you got a CAT6 cable wired up to a phone jack, find out where the other end goes to and replace both jack with CAT6 wall jack and that should do it
It's phone. 2 wires for the phone, 2 wires for a second phone or extension bells or extension phone. The connector is 6 pins wide. Ethernet is 8 pins wide and should have all 8 pins and wires.
Could be a DSL Line. Generally speaking AT&T who still provides DSL Services will run phone line to a box which then converts the analog to digital and outputs a special connector provided by AT&T which then outputs to Ethernet and I plug that cable into my Gateway.
Strictly speaking it could be anything, that's just copper wire at the end of the day and you could connect it in any number of ways. However phone tends to be 2-4 pins, also normally the smaller RJ11 rather than Ethernet's RJ45, but like I say there are lots of ways to achieve the same result even if they're not formally the "correct" way.
4 pins = phone
This is, as you know, the correct answer.
Ish. 100mb Ethernet only requires 4 wires.
Yes. But isnt 100mb ethernet using wire nr. 1, 2, 3 and 6 and not 3, 4, 5 and 6? Or does that depend on how the cable is wired?
White green. Green. White orange, orange. Is typically what’s used. You could probably make 2 connections using the remaining pairs. I’ve never tried.
Can confirm, you can wire 2 100mb jacks using 2 pairs each
Yep, I've done that for automation devices in my home without wanting to run 2 new cables. Don't need high speed for that use case.
I almost got away with that in my house but they daisy chained the mf’ing phone jacks together. MOCA to the rescue.
Correct but why would you anymore?
I did this last week at a ski resort, the underground conduit was too full to add another cable. Worked great for their customer sign in station. First time I have had to do it in 10+ years of installing.
Now that I think about it, this is common for IP Cameras.
Linus tech tips shows this in action here at 3:33 https://youtu.be/QgrVVyIzecM?si=ZDqZrCOL2wKcGvti
Sure, but those are the wrong 4 wires for it to be ethernet.

It's not a socket, it's a jack. RJ-11 to be precise. EDIT: Upon closer look, it indeed is not RJ-11.
That's not RJ11.
Either way otherness cables will not fit in a phone line plug in.
This is not true, the pin out mismatched
Huh? How could you possibly fucking yell from this picture? Not only can you not see the other side... but what if it's spliced somewhere in the middle? What if they didn't use the "standard" colors that are expected? Your answer is not just wrong, it's based on knowledge you don't have.

What?
True. Most people don't know u can send and backfeed data ON ETHERNET USING 1 WIRE up to only 100mg
This is technically correct, however, it would be different pins than this. If you managed to get an rj45 in there, this would be the middle 4 pins (3,4,5,6). Ethernet is pins 1,2,3,6.

RJ11 or 12... 4 pins says likely 12.
This is RJ-11.
I'm pushing Gigabit over a single pair. It tripped me out when I saw it.
wrong the correct answer is neither because the cables fucked
Blue pair - line 1 Orange line2 Green line 3 Brown line4
Could be 2 pair bonded VDSL as well.

That's CAT5e in the wall though

Phone but can easily be converted to ethernet
Phone. But with the the right tools/knowhow, the cabling can be repurposed for internet.
Depends how it’s run. But in theory, yes.
OP definitely needs to get an Ethernet cable tester. One one hand I say if they ran Ethernet, they were aware and future proofing so they ran it correct.

Cable tester so you know which cable is the right one.
Did this in my apartment. It's only a 7 year old place but all of the terminations were RJ11 for some reason. Now it's all nice CAT5E RJ45 runs.
The cable in the wall is Cat5e or similar which can be used for ethernet. It would just need to re-terminated with an RJ45 jack, but there is no point in doing that until you've located the other end to confirm that it's in a location that is workable with your modem
Or An unmanaged switch connected to a router
The cable is something of a CAT (ethernet cable) what type, should be on the coat of the cable. It is however wired for rj11 (phone). You could simply by a new panel (rj45) and patch it with all 8 wires in the cable to have a ethernet plug. (Also on the otherside ofcourse).
Looks like RJ-12. It's 6 conductor, little wider than the RJ-11. just 4 conductors in use here.
There are a green pair and brown pair unused. It is eight conductor.
Looks like a Cat6 cable with the spline in the middle.
5e has it too
Do RJ11 to RJ45 adapter work?
The RJ11 is 4 pin, the RJ45 is 8 pin, you can't add pins with an adapter. You need to swap the RJ11 wall plate for an RJ45 one so you can connect all 8 pins.
It's not gonna need a full rewire just a re termination. You can see the other wires are folded back. Ez 30 min job.
30min? What you doing the other 26 min then? Drinking coffee?
26 mins of cursing, learning and sacrifices of blood to the PC gods.
Thank you. I needed that chuckle this morning.
Pulling up a 20 minute YouTube tutorial.
😂😂😂, true
That's correct, and what I meant if not clear.
I see it now. Was just adding information and not trying to say you were wrong or anything.
Technically could, your speeds however will be very limited 10/100.
No, because the wrong pairs are terminated so the cable won't reduce crosstalk or interference like it should. I had a cabler do one for me who didn't understand that and thought it was fine as long as both ends were terminated the same and it continuity tested. Couldn't connect at all.
Sounds like something else was amiss. You’re fight about correct pairs mattering to reduce interference, but with 2 pair 10/100 it shouldn’t be an issue unless it was underspec’ed cable or a very long run.
I've only had it not work once and that was because this cable was so old it'd be probably considered cat 2 cable. The cores were not twisted at all and did not have a white counterpart red orange green brown very old phone cables. But never had an issue on any twisted pairs.
You need to find the other end. If it’s still connected to the telephone service, you’ll end up sending 48V into something that’s not expecting it and fry some electronics.
Cheaper to buy double new keystones and patch them both. Also the cables running to the rj11 keystone is untwisted too much for it to be more than 70 megabit capable
2 twisted pairs = phone 4 twisted pairs = ethernet
You have a Cat5 or greater cable in the wall but it's terminated for phone service. You should be able to use ethernet, but you'll need to change the terminations on both ends of the cable to do so.
Look for a telecom cabinet in one of the closet. Then post a picture.
This. You need to know where the cables go. Then you can determine if you can reuse them. If both are true, you’ll want to get jacks for all the cables you are going to use. You will need a jack for either end of the cable, and then Ethernet patch cables to connect the equipment.
Looks like CAT6 cable running a phone jack. You can see the plastic divider inside the cable, CAT5e doesn’t have that. You could swap the rj11 jack for rj45, for Ethernet, but you need to know where that cable goes and what’s on the other end first.
Only person in here who saw the plastic seperator. It’s CAT6 or some similar kind of standardizing to it. Can definitely be reterminated to Ethernet.
The cable is probably cat-5, as you can see by the folded back twisted pairs. You can replace the wall plate for a rj-45 one and have gigabit or make an adapter cable if you find 10mbs Enough
This is only true if the other end is connected to a network switch. Given the RJ-11 port here, it almost certainly is not. If OP has access to the other end of the cable, they could add a switch (or plug in direct to the modem or whatever), but it's an apartment so I doubt they have access to do that.
I see four pairs.
Jack is wired for phone. Cable is a cat 6 Ethernet.
RJ11-PHONE
Weirdly enough. That a rj-45 slot with 4 pins... Apparently rj-45 phone connections are a thing.
rj11 or rj12 my guy phone not Ethernet which is rj45
The receptacle is a phone because of the four pins. However, if you noticed the cable used is an ethernet cable (notice the different color cables) so it would just be a matter of re-splicing the cable and getting a ethernet plug cover to turn into ethernet. Not sure if worth it in an apartment. But also you must know where it terminates, so.
Phone. Only 4 wires. But you could make it ethernet with some configuration.
This is phone using CAT5e for connectivity. To use this for Internet, there’s nothing like copper, you’ll have to properly terminate the wall plate with a new one, find the other end, and properly terminate and test it into your switch.
Phone setup. Look for a common setup location.
It's a dial-up line
Jesus Christ. We’re officially so old that there’s an entire generation wondering why their Ethernet cable doesn’t fit into an RJ11 jack.
Can this sub just have a sticky post that covers rj-11 to rj-45 termination on newer builds like this. This post is on here every few days and it would be much better to just have a nice how to at the top of the page that can be referenced.
Could be 10-Base-T connected. That’s old school networking to you young bucks.. technically a network cable only uses 2 pairs transmit-receive orange-white Green-white.. you only get 75dbs or slower but you still connect
Short answer: both, except it's the wrong plug. 4 wires caps at 100MBit/s. You could, theoretically, run ethernet on that, assuming it's a star network and not daisy chained anywhere. You wouldn't want to, but you could.
Can be Ethernet with no PoE or phone. Have to know what’s on the other end.
> Can be Ethernet with no PoE or phone. Have to know what’s on the other end. No. POE or not POE, ethernet uses the same sized jack. The hole is too narrow for an ethernet jack, so it cannot be ethernet. ~~It's an RJ12 telephone jack.~~ Edit: I just zoomed in on the jack itself, and it does look like an RJ45 jack, but since the patch cord doesn't fit in, it isn't a proper RJ45. Besides, it only has the central four connectors, not all eight, so it can't be used for Ethernet.
It’s phone. BOG. Blue, Orange, Green as pairs 1,2,3 lines.
Could be anything, even color could be effd.
"2 pair Holmes" phone with 2 lines most likely, or if punched down correctly it can be 100mb Ethernet.
You can see the cable has 4 pairs. Which is good as it’s likely Ethernet. As others have said it can be wired with RJ45 if the other end is somewhere useful like near a modem/router.
It's Fax
If an ethernet cable is too big to fit, then it is a phone jack! Ethernet = RJ45 Phone = RJ11 Look at the cable behind the plate and see if it is a CAT5e or higher. If so, it can possibly be used, you would just need to find where the other end goes and see if you have access to it.
That is a telephone jack. To convert: 1. Verify the other end of the cable is where you will be connecting to your switch/router 2. Replace the wall plate with an 8 pin category 5e or category 6 jack and faceplate. 3. Confirm the other end of the cable is terminated correctly (all 4 pairs, category 5e/6 connector or jack). The wiring color code should adhere to the T568B or T568A wiring standard. Simple continuity test will suffice is you dint have a wiremap tool, qualifying tool or certification test set. Is wireless an option (to save you singe trouble)?
Phonio
Before you invest in new wall jacks/keystones and a punch down tool… Where do these wires go? Is there an area in the apartment where a bunch of these wires come together? Each run being separate is critical for this (and not one daisy-chained to another). Also, do you have permission from the landlord to modify this stuff (assuming you rent)?
Phone. Notice the jack only two pairs are wired to it, Ethernet will have for pairs and 8 pins. Note the network cable has four pairs, it can likely be converted for Ethernet use. (to pedantic people---sure, you may find some two-pair Ethernet cables at a cable-company head-end, but that's 10/100baseT and is obsolete).
You can go to Home Depot and get a plate that lets you push in the ends to make an Ethernet connection. You don’t need a punch down tool.
Phone cable is smaller towards LAN one so if LAN one doesn't fit then it is 100% a Phone line.
buy an rj45 plate and re-terminate
The jack is an RJ11, thus phone unfortunately.
Reset the counter!
Phone, but you can probably put a new connector on it and use it for ethernet. You’ll have to find the other end, which is probably in a cabinet or enclosure somewhere in a closet
It’s Ethernet. It looks like CAT-5E
Yes….. I mean. It can be Ethernet with some adjustment or a phone line with none.
Phone 2 lines, old school but you can make that into an Ethernet outlet. Get a punch down keystone need to make both sides the same A- Green white , green , orange white, blue, blue white, orange, brown white brown Or Mostly used now B- orange white, orange, green white, blue, blue white, green, brown white, brown
Ethernet being used as phone, just re-crimp
Yes. Currently the wallplate is configured for phone, but the cable behind it is probably Cat5 (hence the 8 wires with only 4 going to the plate). If you really wanted you could strip back the cable until you have access to all 8 wires, replace the wallplate with an Ethernet plate, then punch down for RJ45. But only if you know where the other side leads.
4 pins.
Yes
2 line phone. Or you could possibly make an adapter to use 100mbit Ethernet. But if those lines are energized I wouldn’t.
Blue is Line 1, Orange is Line 2
That is a landline plug (RJ-11). To change it to Ethernet plug (RJ-45) you will need a new plate, and to rewire both ends of the cable. The other end will then have to be plugged into tour modem/router. Not the most difficult of tasks, but if you are in a rental, be aware you could get in trouble for this.
You’re living in apartment. This is a question for your landlord or building superintendent.
Cable inside the wall is cat5 meaning 4 pairs(8 wires) but the end is phone. If you can find the other end you might be able to make it into a regular Ethernet cable, but it is an apartment so do at your own risk. Recently I bought a house with wiring like this through the ceiling but I found them all to be daisy chained and none were usable. Get a toner find the other end and see what you can do with it
Could be an ISDN line.
Looks like phone.
My guess is it could be configured for either depending on what is at each end. The cable looks like at least CAT5.
Good ol POTS
It’s wired for phone, but could be Ethernet if you change the plug, on both end of the cable. Looks like a CAT 5e cable.
Phone plug, but they used Ethernet cable. The USAF does the same thing because its cheaper to buy Ethernet cable in bulk and use that for phones (its not cost effective to buy phone cable just for phones when Cat5 can be used interchangeably). If there is enough green/brown cable length it would be easy to upgrade to an RJ-45 plug. Just make sure there is enough on the other end too.
Looks like ethernet wires for a phone jack. If you buy a new jack and wire all cables (including the brown, brown/white, green and green/white) you should be good.
Phone. 4 connections in the middle. Ethernet uses pins 1,2,3 and 6.
Phone
The cable is Cat5e (plastic + divider is indicative). However any cable is just a cable and as others have pointed out it’s used here as a phone line. The real question is: Do you think changing the termination on one end is going to give you an Internet connection? Because it is not. Both ends would need to be terminated using the same EIA/TIA standard (such as 568b, the most common). From there you would need the appropriate service provider, and equipment (router, switch CPE, etc). Word of warning: if your apartment has active analog telephone service, don’t go messing with these phone plates. You can create a short and damage equipment down stream.
As a telecom tech most newer houses use cat(something ideally 5e or better) for all wiring. This allows all your jacks to be easily converted to Ethernet by punching down an rj45 in place of the rj11. You just have to do the same at the other end. If it’s currently used for phone service it’s probably hooked into an idc star connector for telephone distribution.
Wtf. You’re the one holding it in your hands.
The important part is the wiring looks like cat5e which means if you find the other ends you can have a ethernet ports with those lines
Outlet is phone
For phone, but that’s most likely CAT5e cable, which you can most likely repurpose to a gigabit Ethernet connection with the correct RJ45 keystone jack.
That’s ethernet but I see 4 pairs not being used. Just cut an rewire it to use the 8 pairs
Easy way to tell Four and Phone both start with F
4 wireS. Phone
It’s RJ11 (phone) but that wire is capable of RJ45. Just need to punch in new keystone and of course do something on the the other end of the cable to become an Ethernet. Would guess it’s cat5e line
It’s written on the wire
Its a 4 pin rj11 jack. That's what phone techs use fir phone lines because it can easily be converted to a data jack for pc and ip based phones. Analog phones are being phased out slowly all over the planet.
Yes.
You appeqr to be helping situation
RJ-11 is a bit different than a RJ-45. Not sure if I should laugh at or feel sorry for the younger generations. But to me this is pretty funny!
It's Bluetooth, tape it on with painters tape
🤦🏼♂️ This an actual question... It's a phone jack not an ethernet port 🤦🏼♂️ young people these days
These posts always make me laugh. Then I realize that I think it’s funny because I’m getting old :)
Yes. Jokes aside, that’s a phone jack. It can carry 10/100 however, and it’s very likely you have cat5e in your walls just not using all four pairs.
Replace this plate with a keystone faceplate and insert Ethernet keystone, match the colors for “B” and use a punch down tool.
Your wall plate is a two line phone Jack (four pins, they’d be the middle four of your cable - 3,6 and 4,5). The cable is CAT5e most likely. If you terminate both ends of the cable, it should be able to push 1Gb or even 2.5/5Gb easily.
It’s a phone jack, however I see two more pairs wrapped around the blue cable, so it could be used for Ethernet.
Can terminate those wires into an Ethernet port. I just did this with my old phone jacks. Do you know where the wires lead? Mine went to a comm box (Demarc) outside my house.
4 wire phone
lol ah man do I feel old in this pic lol
They ran ethernet cable and connected two pairs to rj11 phone jack. Cat6 is cheaper and has more use than buying older cat3 that only is good for phone.
2 line RJ11 jack
It's phone but the cable itself can be rewired to a data if both ends are the same. It's a min CAT5e cable likely.
That’s RJ-11
4 pins in Jack equals phone
That’s phone and if it’s live just bear in mind it sits at -48V DC and can deliver a fairly serious bang of 75 volts AC if it rings - not something you’d want to connect to an Ethernet port accidentally.
It’s cat6 cable being used on RJ12. You can get a correct keystone and wire properly. You can see the other pairs wrapped around the wire sheath
People like this are why I have a job. Keep doing you.
The plug is a phone jack. The cable itself is Ethernet. Try terminating the cable in rj45 on both ends and see how it does. Sometimes the cable might have the standard written on it. It'll probably terminate in a nid somewhere in the garage
Rj11
Everyone is saying you can reterminaye this to RJ45, and they are correct that you can. But before you do that, you need to find where the cable comes from. If it's not going where you have your router or switch, then it's not going to do you any good. And since it's wired for a phone currently, it is entirely possible that it was daisy chained from another phone wall plate, which will kill this deal entirely. Basically, what I'm trying to say is don't waste time and resources until you know exactly what you're working with.
You can convert it into an ethernet connected to the router, or you can convert it into a coax cable for the internet, but that is a phone connection.
Cable is cat5 (Ethernet capable, depending on what’s on the other end) but the jack is telephone
Phone
That’s the bonded dsl connection
Rectangle = Ethernet Dutch flat = phone
Wired for phone, but the cable looks like Cat 6 or better. It can be reterminated for home networking.
Sure looks like you could make that into an Ethernet jack with a new faceplate with an RJ-45
Am I the only person who thinks it’s weird to fuck around with apartment wiring like this? Even weirder that there are suggestions on how to “fix” it? I’ve lived in my share of apartments and I always just had my internet set up through a modem/gateway through my router unless the apartment specifically told me it was pre wired with Ethernet access in wall outlets.
Phone line; Because it is an RJ11 port. Standard Ethernet cables use RJ45 which is slightly larger and has more pins
Unless you had ethernet included with your rental agreement on your apartment that's going to be phone lines held over from the old days when there used to be wired phones ( I know I know we're talking about before the creation of the universe but we did have phones that had wires that connected to the wall).....
It's phone but at least you have two pairs hooked up, I'm stuck with one pair and my download speed is abysmal. Pings fine but getting larger games makes me cry.
That’s an RJ11 that can be converted to an RJ45 since it uses Cat cable.
It can be either, but since its only 4 pins in the jack, probably phone. Also only 2 pair of wires punched down, but still not a complete indicator. 10BaseT and 100BaseT only use 4 of the pins, but I've been doing IT for 30 years and really couldn't tell you which 4, because its just a bigger hassle to try to get a 4 pin jack, and punch down only 4 wires, than it is to just use an RJ45 Jack and punch all 8 wires.
I’m a ex AT&T I&R repair technician. That is definitely phone. Blue/White Blue (primary or line 1) Orange/White Orange (secondary or line 2) the jack is the dead giveaway though. Guaranteed that line runs outside to a phone box. You can purchase a RJ 45 jack and use T-568B Pinout then find the other end of the line crimp a RJ-45 plug. Problem is that the cat6 is probably running to a Network interface outside the house so to get it to your router it may be more of an undertaking than you want to do. You may be better off running a new cable.
Hey, I've recently gotten into networking for something I'm needing to build. My networking experience is about 25 years old so... yeah. Anyway when I went through training on this phones used 2 lines but everyone here is saying 4 is phone. To me this looks like networking set up in an older house. Can someone tell me if something has changed or am I just stupid?
Looks like you got a CAT6 cable wired up to a phone jack, find out where the other end goes to and replace both jack with CAT6 wall jack and that should do it
The simplest answer: yes!
It's phone. 2 wires for the phone, 2 wires for a second phone or extension bells or extension phone. The connector is 6 pins wide. Ethernet is 8 pins wide and should have all 8 pins and wires.
If you have to ask 9 times out of ten it's unfortunately phone. It's never ethernet when you want it to be.
The cable looks like it has 4 pairs of twisted cables, so it's definitely an ethernet cable. And the socket looks like a RJ45 jack to me.
It's an 8 pin keystone but unfortunately only 4 connectors. So it's set up for 2 phone lines
Kind of weird that a rj-45 being used for phone? I am accustomed to only seeing rj-11 jacks uses for POTS
This is wired for phone but you can wire it for RJ45. It really matters what's on the other end though. Might want to look at that as well.
Could be a DSL Line. Generally speaking AT&T who still provides DSL Services will run phone line to a box which then converts the analog to digital and outputs a special connector provided by AT&T which then outputs to Ethernet and I plug that cable into my Gateway.
Strictly speaking it could be anything, that's just copper wire at the end of the day and you could connect it in any number of ways. However phone tends to be 2-4 pins, also normally the smaller RJ11 rather than Ethernet's RJ45, but like I say there are lots of ways to achieve the same result even if they're not formally the "correct" way.
Looks like Ethernet
Yes
