I've found this which lists them all - http://kropla.com/phones2.htm - however it is copyrighted. Can a list of information be copyrighted? Secretlondon 17:34, 3 Jul 2004 (UTC)
- Depends. Not in the UK, but you can claim something along the lines of "impression copyright" on the actual presentation, which is why its illegal to photocopy or OCR the phonebook/yellow page/thomson directory but it is legal to retype all the data by hand... Kiand 02:22, 15 Feb 2005 (UTC)
- I requested the author for permission to use the information. Oh by the way, isn't RJ14 used in India for telephone lines that provide Broadband Internet connections? Not sure but I've seen them in Broadband enabled telephone systems. --ADTC 18:11, 1 October 2006 (UTC)
This site sells adaptors and has photos - laptoptravel.com - note that it contradicts the first site in some places. Secretlondon 18:24, 3 Jul 2004 (UTC)
Older German standard
[edit]There seemed to be German standard de:Anschlussdose before standard TAE (currently solely mentioned in list). --Abdull 17:40, 28 May 2006 (UTC)
== It is still not clear in the Telephone Plug description if it is female or male.
Older British Jack?
[edit]Wasn't there an early type of GPO Phone Socket, which was bulky and looked like a large Jack Plug?
Old US Bell Connector type?
[edit]Does the old Bell connector have a name, or desingation?
Oh, I also deleted the merge thingy, as that has been taken care of

- Is that the one with the four round pins in an almost-square trapezoid? I remember seeing it when I grew up, but RJ-11 has completely displaced it now. It should still be referenced, if anyone can find more information about it. 71.41.210.146 (talk) 12:09, 18 February 2008 (UTC)
- I've got an old four prong cord in a drawer. I'll see whether I can make a good photo. Jim.henderson (talk) 00:01, 24 February 2008 (UTC)
Why doesnt it mention the common mistake....
[edit]over and over, people have repeatedly mistaken phone jacks/ telephone plugs, for ethernet plugs. because they look exactly the same, but ethernet is wider. but because the plugs themselves are usually clear, its impossible to tell its width if your looking in a tangle of wires. there needs to be a mention of that, that they should not be confused. —Preceding unsigned comment added by NullVoid Omega (talk • contribs) 22:33, 17 December 2007 (UTC)
Norwegian phone jacks
[edit]Norway does not actually use the RJ11, although the plug used is compatible with RJ11 phones and equipment.
The actual plug is an 8P?C -- as I no longer live in Norway and never thought to check when I did, I don't know how many of the conductors are actually connected. I suspect it depends on the number of phone lines a subscriber has, in which case this might actually legitimately be an RJ45 connector.
I've not updated the page because I don't know how to describe the actual jack; I'm hoping somebody in Norway can investigate which variation of RJ45/8P?C applies. -Stian (talk) 05:27, 6 July 2008 (UTC)
Norwegian pinouts and plugs.
[edit]The old 3 prong outlets used the 3 pin for different purposes depending on system. Moast common grounding for recall of register in offices. Earlier systems and party lines could use thid for reingers between ground and one of the lines. Extra ringer would be put in series with this 3'rd line. Moast installations did not use the 3'rd pin, but were used as this: http://img.photobucket.com/albums/v480/dsk/Telephone/Telefonkontakt1.jpg (I have trouble with uploading pictures, but feel free to use this, its mine) The 8/8 plug is configured as 6/6 plugs, usually only the 2 center pins used. dsk —Preceding Dsk (talk • contribs) 14:29, 11 August 2009 (UTC)
Polarity on RJ11 & RJ14 should always be reversed (like patch cables)
[edit]Polarity on RJ11 & RJ14 should always be reversed (like patch cables)
Polarity pin-outs are is reversed on POTS / PSTN cables Particularly in DSL cables, but also generally.
E.g., on an RJ11 the center wires will be
Green / Red on one end, and
Red / Green on the other.
On an RJ14, the pin-out wiring on one end will beL
Yellow / Green / Red / Black
and on the other, exactly reversed:
Black / Red / Green / Yellow.
(You forgot to sign.)
- As the article says, the tab goes on the same side of the cable, so yes they cross if you look at the same plugs. But most phones now are polarity independent. I needed one that wasn't crossover to connect a VoIP box to a wall outlet, though. Gah4 (talk) 04:18, 1 June 2018 (UTC)
demarcation
[edit]As far as I know, outside demarcation is now usual for US phone wiring. Is this also true in other countries? Gah4 (talk) 04:19, 1 June 2018 (UTC)
- Continuing this, there was some time in the early 1980's when inside wiring went from being owned by the phone company to being owned by the house owner. Before this, the phone company could regulate things like which jacks were installed, and how many phones were attached. Though often people did their own (re)wiring even before that. The date of this should be mentioned. Also, how were/are things done in other countries? We tend to believe that we can plug into anything that fits, but I suspect that some countries still regulate what can be connected. Gah4 (talk) 20:05, 9 April 2020 (UTC)
