Get 2 or 3, 4 gang blank wall plates and fit the RJ11's (or RJ45's) to them.
The it's just a simple matter of connecting them with Cat-5. Puch it in with
a Krone tool. Should only take about 10 minutes.

Kwyj.

I got an 8 port faceplate with a surface mount box with cat 5 snap in
connectors which will take RJ-11.  I terminate all the house LAN wiring in
here as my patch panel.  Not cheap though.  $10 for the box and plate an $2
for each RJ45 connector.

Sure, that bit is easy enough.

Yeah, was a bit tempted to go the whole hog like that.

Tad of an expensive approach compared with what I want tho.

These are all floating cables, not part of the house wiring etc.

Try a store that sells telephone stuff.  I got a little box
(3-1/2"X1-1/2"X1-1/2") that contains 5 RJ11 jacks wired in parallel -
all connected to a short cable ending in an RJ-11 plug connected to the
jacks.  I think it cost about US$5.

Rat Shack has a 1-to-5 adapter. Steep at US$10 but quick fix.

Have a :) day!

I should point out that you're all wrong, even the mighty Rod Speed...
RJ11 is the little 4-pin connector which is used to link the handpiece
with the telephone unit. RJ12 is the slightly bigger 6-pin connector
you are talking about.

Dick Smith sells RJ12 triple adapters, but you can't gang them without
using other connectors. I recommend:

1 x RJ12 triple adapter, 3 x 8cm length of phone cable, and 2 x RJ12 double
adapters with sockets all around.

The RJ12 triple adapter is the type with 1 plug and 3 sockets, as Dickie
sells. The 3 lengths of cable you can buy or make, generally it's cheaper
to just buy them. Plug each into the triple adapter. Then on the ends of
the cable, plug the RJ12 double adapters. You've now got 6 sockets to
plug phones and stuff into, and Ringer Equivalence limits be damned!

RJ11 is not smaller, just fewer (4) pins.  Don't know what it's like
Down Under, but the US uses RJ22 for the handpiece-base connection
IIRC.

We'll see.

Fraid not. RJ11 usually called 6P4C, 6 positions, 4 conductors.
RJ12 is 6P6C, all 6 pins with wires connected to them.

The smaller handset jack is a 4P4C, forget the RJ number.

Yeah, thats what I'm currently using and commented on
that problem that you cant stack them into yet another
triple adapter or even a double. Basically lousy design there.

> I recommend:

Yeah, thats what I was planning to do if I couldnt find the more
elegant long strip of about 10 RJ11s all wired in parallel.

Its obviously possible with punchdown RJ11s but you've still got
the problem with mounting the RJ11s themselves somehow.

Obviously a standard patch panel plate would be fine,
but it again isnt that elegant to mount when there isnt a
rack to put it in, and the whole thing aint cheap compared
with say 10 pcb mount RJ11s and a pcb to parallel the pins.

The top entry pcb mount RJ11 sockets would be best too.

Yeah, but its not as mechanically tidy as say 10 RJ11s on a pcb.

Yeah, dont give a stuff about that with modern electronic phone devices.

I think you're right here (after I did a google search...). Sorry about
that.

It's just because they'd like to make the piece as small as possible.
I use a double at home here, plugged into the patch panel, and there's
_just_ enough room to get a plug and cable into the socket right next
to it.

Done a google search yet? I haven't heard of them, but if you can
find one that would be ideal. Of course the telephone network
wasn't designed to handle 10 devices in parallel due to the
excessive current drain, but recent technology loads the line
a lot less than the clunky bell handsets which the system was
designed for.

Try TLE and J.R.Turk for telephony components. They do trade sales
but also sell direct.

Course you could always do what I did, and get a rack to put it
in. Then you can put in old computers, hardware, basically a rack
can be a big shelf too.

Yeah, the RJ numbering system is yet another example of something
thats completely outgrown its origins and the number itself leaves a
hell of a lot to be desired now. Thats why the 6P4C style system is
used now, much more useful. With RJ11 and RJ45 still used to
loosely describe 6 wide and 8 wide physical bodys.

No problem.

Dunno, it appears to be more that its easier to design them like that.
Basically its easier with all the pins in a horizontal row, both in the input
connector and the output connectors. That automatically means that
you cant go sticking 3 triples into another triple to get a total of 9 tho.

Sure, but I was really talking about stacking say 3 triples into another triple.

Yeah, not much around. And it aint trivial to

One that Dave sent me by email is
http://www.clipsal.com.au/scripts/Alf4Web.dll?ShowCatNo?CatNo=8058/8RJ
Bloody thing is $85 retail tho.

Yeah, I'm sure thats why they arent readily
available off the shelf like the triple adapters.

OK, thanks for that, I'll try those today.

Yeah, I was trying to avoid that, Basically going for something
completely different rack wise, made out of 12mm RHS.

The patch panel approach isnt that elegant compared with a
small pcb that you can solder say 10 top entry RJ11 pcb sockets
into. Guess I should just get off my arse and make the pcb.

The main hassle is that since the pins are on a 0.05" pitch,
you cant just use strip board. Unless someone knows of
any 0.05" stripboard. Couldnt find any googling for that.

One other approach might be to butcher 3 triples, break
the plastic away on the single plug side and mount 3 of
those on some 0.01" strip board or just wire between
the pins directly. Specially if only 2 conductors are used,
that might be the easiest approach. Just glue a strip of
plastic down both sides to make the whole thing solid.

It'll still end-up looking like a birdsnest when all the leads are
plugged in ...... unless you hide 'junction central' under the
desk, or some-such. 

For a 12 outlet flush wallmount -

http://202.139.241.237/products/catalogue/detail2.asp?strItemName=12 Port Dual Gang Faceplate


For a multiple outlet extension lead -

( alternatively, you could use the gear mentioned above + the
appropriate wallmount box on a lead )

Get two 32mm ( or 37mm? ) wallmount box's ( the standard electrical
wall stand-offs ) and join 'em back to back. Get two Clipsal  or HPM
faceplates with the appropriate number of outlet holes ( a 4 hole
faceplate will be the most number that'll fit the 'RJ11' size Keystone
outlets, I think ).

You'd need the adaptor rings for the Keystones to fit the faceplates -

http://202.139.241.237/products/catalogue/detail2.asp?strItemName=Clipsal/HPM Adaptor

..... but it looks like there's suitable sockets that fit directly into the
 faceplates ( so 6 outlets per faceplate may be a goer ) -

I dont care about that, just what they are being plugged into.

A patch panel for example is gunna be a lot longer, and
a wall plate and box rather bigger than it needs to be.

> unless you hide 'junction central' under the desk, or some-such.

Yeah, thats what I do currently, must need more RJ11 sockets in that.

Thats physically quite a bit bigger than say 12 top entry pcb mount RJ11
sockets on a pcb or 4 triple adapters glued together side by side with the plug
end plastic broken off and the pins on the adjacent adapters soldered together with
say a blob of silicon sealant or epoxy over the soldered wires once thats done.

: RJ11 is the little 4-pin connector which is used to link the handpiece

Common use for the RJ names is:
The 4 pin with 2 installed is an RJ9.
The 4 pin with 4 installed is an RJ10.
The 6 pin with 4 installed is an RJ11.
The 6 pin with 6 installed is an RJ12.
The 8 pin with 8 installed is an RJ45.

Reality is bit different.
RJ-11 is a 6 pin modular connector with the inside pair as tip and ring.
RJ-12 is a 6 pin modular connector with the inside pair as tip and ring and
the second pair to indicate the line is in use but will only have 4 contacts.
RJ-13 is about the same as an RJ-12 (a 4 wire standard)
RJ-14 is a 6 pin connector with the inside pair as line 1 and the 2nd
pair as a second line.

I've been able to find the 6 conductor jacks that fit in a standard
wall plate from an electronics supply place but they were $8 each.
I wanted to maek sure people didn't plug ethernet wires into the
phone lines.  I could have put in RJ45 for 1/2 the cost.

In the 1970's, AT&T and the FCC developed a system called USOC (Universal
System Ordering Codes) which was/is a set of wiring specifications for
terminating telephone lines.  The USOC system uses RJ (Registered Jack)
numbers to specify the WIRING of a jack/plug, not the actual jack type.
Telecom Australia (now Telstra) developed a similar system (Specification
1222) of various MODES which refered to the WIRING of either 610 telephone
sockets or 611 auxillary equipment sockets.

Through common misuse, the RJ numbers became defacto names for the various
US modular plug variants.  For example, using an RJ number to describe an
actual plug variant is often confusing because different people use RJ11 to
describe 4P4C, 6P2C and 6P4C plugs... none are correct!

Same problem with Australian sockets, the 611 socket is often incorrectly
refered to as a MODE-3 socket.

Yeah, thats what I meant, spelling out the detail more.

Thats going too far. You cant claim that only the original is correct now.

Sure.

What do they call 4P4C then?
I have some cables I was going to make with 4P4C but my crimper only does 8P
and 6C.

More commonly (but still incorrectly) 4P4C is called RJ22

4P4C plugs are usually used for the coiled handset cord.  3-in-1 tools are
available that will do 4P, 6P & 8P plugs, see
