A 6P4C is an RJ14. It's NOT another RJ11 (which is only a 6P2C). The RJ14 are used for two-line PSTN telephones, adding two wires (yellow and black) on each side of the center two (red and green) for the second line. Has primarily very small business and residential application. The narrower "handset" plug and matching jack are an RJ22 or RJH; both designations are used for it. They were created to idiot-proof handsets and their cords to prevent them from being plugged into the wrong jack on the instrument, or into a PSTN FXS jack, albeit it doesn't stop some complete idiots from attempting to force it to fit anyway. The 6P6C RJ12 and RJ25 are commonly used in commercial and industrial applications for PSTN phone systems. The difference between them is their specific application, with the RJ25 the most common for carrying three PSTN lines with pins 1 and 6 carrying the third line.
I am in California U.S.A. I have looked everywhere online and in our local stores for the RJ10 plug and crimper and have had no luck in finding them. i checked out your website but did not see where to purchase anything. can you help me out?
what is the difference between a RJ9 and RJ10 and RJ22 4P4C? I am trying to create a ict220 cable for Point of Sales devices however the internet sources indicate that there is an RJ11 at one end and a RJ45 on the other. I believe that is this incorrect since I have a cable where one end is RJ45 but the other one is smaller than a phone Jack I can only assume that it is a RJ9 or RJ10 or RJ22 spending time in Trial and error is not an option since I don't have the jacks available. Can you please shed some light on what the smallest jack size is? thanks
I have 2 modem and their dsl port is 6p 2c. But the cable doesn't plug the other one. The one I can't plug is more like rj-12 bec it is thin. But both of them is 6p 2c. What should I do?
thanx so much, the issue im trying to sort is my mums slow internet , our isp are talktalk and plusnet who i have just moved to they sent with our routers 2 p 6 c (only 2 gold pins) to go from phone socket(with filter) to router when i plug in a 6p6c( 6 gold pins it did speed up her internet but then i worried it could cause fire as the filter that come with it only has 2 gold prongs inside, so for safety just replaced the 2 pin one for new then i check my cable which i swapped for a longer one to discover it has 4 gold bits and my internet is faster than hers and it not caused any probs for me the last few years lol......was i worried for nothing, i want to put the faster one back for her????
how do u tell if u have rj11 or rj12 if u just have the ports? i have some ports in my house that i thought were ethernet but turns out they're either rj11 or rj12 and i wanted to buy an adapter to change it to ethernet
Vince Hi, I'm from UK I want to move my sky router from hall into cupboard but the cable isn't long enough. I'm going to buy cat5e cable, I would like to have a socket in cupboard for the router, what would I need to get from your ebay shop to complete task. My master socket is a bt MK4
cachememory Hi, if you were using a 2 core cable then yes you can use a 6P/2C, 6P/4C or a 6P/6C but if you were using a 4 core cable then you can use a 6P/4C or 6P/6C and if you are using a 6 core cable then you can only use a 6P/6C. There is no speed differences between the plugs, the only difference is the amount of gold contacts present. I hope this answers your question.Many thanks Vince
Thank you for your detailed answer. Though this raises another question: How do I recognize the number of cores of the cable? Should that be given in the technical specifications if present?
cachememory Yes, it will often mention the cores of the cable in the spec or if you already have the cable you can normally see the cores through the clear RJ11/RJ45 plugs. Also if you are using the flat profile cable which is very common on various leads then the width of the cable will be different between 4 core, 6 core and 8 core.
Thanks ... Informative video ... One other note of confusion though is that in addition to the "RJ-9" in the States being synonymous with the "RJ-10" in the UK. The 6P6C "RJ-25" in the States is the same as the "RJ-12" in the UK.
Sir i need you help i just bought a wireless n router and i dont have any router is tgere any modem cable from adsl to ethernet so that i donot need any modem device just a simple cable that convert adsl to ethernet 4 pair plz help
I've been scouring the internet for answers and this is the best info I've found. I've now identified my AT&T DSL's modem's(gateway 4111N) "Broadband" jack to accept 6P4C RJ-11 connectors. However, the connector, which we have not replaced since installation almost a decade ago, has 2 grooves on the top side in front of the release latch that allows it to snap into my modems(which we have changed over the years). I'm looking to replace my CAT5e line that runs from our NID outside the house(it goes in through a window and straight into the modem) but without the right connector on the other end it would be useless. Any clue as to what kind of plug it is? I've searched on the internet for a week now with no relevant results, just talk of RJ-11s being used for phones. TL;DR : My router will only accept 6P4C connectors with 2 special grooves on top, any idea what type of plug it is?
Just discovered, to my cost, there is an RJ12 with offset clip (on ebay RJ12 DEC Modular Connector Plugs with offset tab Latch) ..these are 6 pins In my BT Converse 1300 they have only two pins (RH viewed from above) and are used for DC power .
Xcalibur Prime Hi, for ADSL between the wall socket and the ADSL Modem Router you would need either a RJ11 (6p4c) or RJ12 (6p6c), both will perform exactly the same.Thanks Vince
This is the most important video on the internet.
Straight to the point and exactly what I needed. Thanks!

Thank you! I never knew the proper designation for the plugs. This has been extremely helpful!
P & C is that UK lingo? I have never heard them described as that before.
Thanks. Is a RJ11 crimping tool the same as a RJ12 crimping tool?
I am in California U.S.A. I have looked everywhere online and in our local stores for the RJ10 plug and crimper and have had no luck in finding them. i checked out your website but did not see where to purchase anything. can you help me out?
this video is better than Wikipedia page. thanks a lot.
I felt same

i went on ebay to get a load of RJ45 as my ends always snap it also says its a Cat6e but seems to not fit any sockets. is this a different type?
thanx so much, the issue im trying to sort is my mums slow internet , our isp are talktalk and plusnet who i have just moved to they sent with our routers 2 p 6 c (only 2 gold pins) to go from phone socket(with filter) to router when i plug in a 6p6c( 6 gold pins it did speed up her internet but then i worried it could cause fire as the filter that come with it only has 2 gold prongs inside, so for safety just replaced the 2 pin one for new then i check my cable which i swapped for a longer one to discover it has 4 gold bits and my internet is faster than hers and it not caused any probs for me the last few years lol......was i worried for nothing, i want to put the faster one back for her????
Does there is an adapter that can adapt a rj11 to a rj12?
Which is a better option to use for my dsl modem?
RJ11 6P2C
or
RJ11 6P4C
how do u tell if u have rj11 or rj12 if u just have the ports? i have some ports in my house that i thought were ethernet but turns out they're either rj11 or rj12 and i wanted to buy an adapter to change it to ethernet

What is the use different between rj11 6p4c and 6p2c? When to use each one?
Tank you for your great explanation. Having a RJ45 jack, can you please give me the wire mapping to a 4p4c (RJ10) for Ethernet? Thank you!
Thanks for the explanation. Is a 6P/6C cable downward compatible with a 6P/4C or 6P/2C connector?
cachememory Hi, if you were using a 2 core cable then yes you can use a 6P/2C, 6P/4C or a 6P/6C but if you were using a 4 core cable then you can use a 6P/4C or 6P/6C and if you are using a 6 core cable then you can only use a 6P/6C.

Thanks again for your help! Wish you the best!
Hey! Can you create video about diffrences between RJ45, RJ45s and about 8P8C and 8P2C? It will be great, beacouse I see there is chaos about it.
Excellent Idea, and perfectly executed into an excellent video! Brilliant and superb!
Thanks ...
Informative video ...
One other note of confusion though is that in addition to the "RJ-9" in the States being synonymous with the "RJ-10" in the UK.
The 6P6C "RJ-25" in the States is the same as the "RJ-12" in the UK.
And I guess the 6P4C "RJ-14" in the States has no RJ- number counterpart in the UK other than as the 6P4C variety of the "RJ-11?"
This videos was so helpful for me. I need to change my cable. It is probably rj-10 or rj-11. I am going to check when I get home. Thanks man
Sir i need you help i just bought a wireless n router and i dont have any router is tgere any modem cable from adsl to ethernet so that i donot need any modem device just a simple cable that convert adsl to ethernet 4 pair plz help
Hi, no unfortunately there is not.
Never heard of RJ10 but that is what I was looking for. Thanks for the video.

Omg! He is still uploading videos 😄
Just discovered, to my cost, there is an RJ12 with offset clip (on ebay RJ12 DEC Modular Connector Plugs with offset tab Latch) ..these are 6 pins In my BT Converse 1300 they have only two pins (RH viewed from above) and are used for DC power .
thanks for explaining
Hi Vince, which is the best for ADSL? Thanks.
Xcalibur Prime Hi, for ADSL between the wall socket and the ADSL Modem Router you would need either a RJ11 (6p4c) or RJ12 (6p6c), both will perform exactly the same.Thanks Vince
Thank you so much Vince
Hi Vince,
Is p6c4 cable faster than p6c2 ?
+Obalions O Hi, no there will be no difference in speed for ADSL, one just has 2 contacts and the other has 4 contacts.
Second thoughts by the BT plug!
Great information. I was so confused and now I know. Thank you so much.
Thank you so much for this video. It helped me so much!!!

Thank you! Huge help sorting thru cables online.
Thanks for showing the difference between these, it's helped me massively
thanks for the video, you cleared all confussions
I'm in trouble with RJ9.
Your RJ10 seems to be RJ9.
RJ9 is 7.6 mm large
RJ10 is 9.6 mm large
Everything else is the same.
(I have both in hands)
( starts at 1:30 )
Good information. Thanks !
Very helpful video, thank you so much , keep it up
did you say telescope?
Arron Somerville Yes, rj12 and rj45 are used in a variety of products, not just telecoms and networking.
Thank you! Almost ordered the wrong plugs
All these people from other countries always have to mention America lol
