Hello,

Very quick questions : (may be some of you guys, can answer me..)
I wish to make some RJ11 cable by myself. (I would need 2 extensions of > 20
meters for my future ATA ! .. (as I do it with RJ45 cables)

I did look on a schematic for the RJ11 on the web
and I am surprised to see an RJ11/RJ14 with 6 cables!?! (I thought it was 4
!?

- Is there any Standard wiring for RJ11 ?
- What is the RJ14 for ???

Thanks in advance

Stephane

RJ11 is just a connector AFAIK. There's a series, which from memory
looks like:

RJ10 4 contact connector.
RJ11 6 contact connector with only middle 4 contacts fitted
RJ12 Same as RJ11, but all 6 contacts fitted.
RJ45 8 contact connector.

Not heard of it, but a quick grock on google and it looks like
it's the same connector as RJ11, referred to as RJ11 if only
middle pair used, and RJ14 if outer pair of the 4 contacts also
used.

in the US the centre two pins are used for 1-line phone systems, the
next pair out for 2-line and the 3rd pair for 3 line.

So you can have a single socket serving up to 3 lines. My 2-line phone
can run off one socket or two separate ones.

6 wires. There's only one plug involved here, the numbers you quote
refer to how its being used.
