I have run in cat5E cable from our stair cupboard to various rooms in the
house. I use these for a network and for our analogue telephone line
extensions.

The terminations are a bit of botch at the moment and I intend to fit a
small patch panel and terminate all cat5E cables in the panel. The remote
end of each cat 5 cable will be terminated in a RJ45 outlet.

Searching the web I'm struggling to find and easy way to patch our BT phone
lines to the panel.
I have found RJ45 plugs to BT sockets which would allow me to plug a phone
into a RJ45 outlet. But at the panel end I want the opposite a BT plug to
RJ45 socket to fit in the BT socket so I can then patch to the panel. Do
these things exist or is there and easier way to achieve what I want.

Secondly to connect my broadband router to the patch panel I'd like a RJ11
to RJ45 patch lead. At the moment I'm doing this with a two leads and a RJ11
to BT coupler connected to a BT to RJ45 coupler.

I hope if standard parts are available I won't have problems with connecting
the correct pairs.

Thanks for your help.

I made them using an RJ45 plug, and a BT phone plug on a patch cable.
Actually, I managed to get two patch cables into the RJ45, thus giving
me up to two phone circuits over each cat 5 4-pair.

There appears to be no standard for mapping the phone connections to
RJ45 pins. I found 3 different manufacturer's adapters, and they all
used different mappings.

Not sure why you want to route the broadband across the house.
I suggest putting your master socket, broadband router and hub
all in the stair cupboard.

the correct pairs.

For phone over RJ45, there is no standard.

But RJ11 fits into RJ45 (and connects to the middle four pins). So just
use a standard RJ11-both-ends lead.

Thanks for reply Andrew.

For my existing setup I bought a couple of BT extensions cut one end off and
connected it to the cat 5 via a terminal block. I will try crimping a RJ45
plug onto the extension to make my own patch lead.

My mistake about the broadband router, it is in the cupboard and is
connected to the BT ASDL socket with the two leads and couplers I mentioned
and isn't very tidy. The RJ45-RJ11 patch lead is to make this connection
with a single short lead.

Looks like I will have to do a bit of adapting.

Thanks for this. I've just tided up my connection by doing this. It probably
explains why I couldn't find a RJ11
to RJ45 patch lead. A good day when you learn something (wish I'd known
this a couple of years ago).

Yes. Simply crimp a BT plug onto a bit of phone cable and wire it to the
back of your panel and mark it 'BT incoming'

All sems realy complex. Why not a simple bit of cable with RJ11 and RJ45
one each end.

I have done the same sort of thing in our house. I ran cat5e all over
the place and while I was at it connected a run directly to the master
phone socket (it punches down just like phone wire). I now have a port
on the patch panel that acts as the master phone socket. That plugs into
a hub/splitter and I then simply patch in any of the Ethernet ports I
want to use as phone sockets. I admit I built the phone "hub" myself but
it was really easy just soldering a bunch of cables together and
sticking them in a box. Coloured socket covers are a very useful way of
stopping you from accidentally plugging computer equipment into phone
lines etc.

Been there, done that. My magic formula goes like this: use the LAUs
you've found - RJ45 plug one end, BT socket on the other - at the
'office' locations. LAU, meaning I think Line Adaptor Unit, is what the
structured-wiring wallahs sell for this job; you want the 'totally
plain', passive, flavour, not the 'master' or 'secondary'.

At the phone incoming location, I made up a compatibly-wired
BT-plug-to-RJ45 socket, by butchering a couple of BT-to-BT leads and a
couple of RJ45 patch cables; joint made using small terminal block
inside an adaptable box (3 incoming lines here - 2 over HomeHighway, one
'ordinary' taken post-filter ADSL (so I have only one filter, in the
master socket, and take all the extension lines including the one going
to the patch panel on the filtered side - saves all that fannying about
with microfilters; I also feed the ADSL side, which my master socket
offers on an RJ11, into another of the structured-wiring ways. (As Bob
Eager pointed out, RJ11s go into the middle 4 of an RJ45 by deliberate
design.)

'Compatible' above just means that the combination of the LAU wiring
(for which there's no accepted standard, so buy several of the same make
in one go!) and the homebrew cable, when joined 'straight-through' over
any number of RJ45 patchleads, acts like a simple BT plug-to-socket
extension cord. A coupla minutes with a multimeter sorts out the
necessary wiremap.

OK, that's the phone-input side and office-output side. At the patch
panel, I use 3-way RJ45 all-female couplers to feed the phone signal to
as many 'output' drops as makes sense: 3-way because each one other than
the first and last has two 'bus' connections and one 'drop', if you see
what I mean. If your patch panels aren't too dense, you can instead use
a one-male two-female RJ45 adaptor and plug that straight in to the
patch panel.

I hope if standard parts are available I won't have problems with connecting
the correct pairs.

Sorry, but I think you'll have to accept one bit of homebuild wiring for
the BT-plug-meets-RJ45-plug bit, because (a) LAUs vary, and (b) in 'real
office' installs, they punch phonelines directly into fancy-pantsy
structured wiring feedpoints which cater for many (12? 16?) incoming
lines at a time. If you don't have crimp tools for both RJ45 and BT
sockets, as most of us don't, chopping into presupplied cables is the
way to go; be warned that UK phone-style cables are often wired in
weirdo (litz?) wire - hard-to-connect-to copper strands interwoven with
a fibre substrate of some sort, which you won't be able to solder to -
fold it back on itself once or twice before using a suitable pressure
connection.

I found a neat little short cable with BT plug on one end and small IDC
box on the other; ideal for the job.

Used for flexibility, but it isn't Litz wire. Litz is individually
insulated strands that move from the surface to the middle of the weave
and back again, to lessen 'skin' effects at RF. Not that the name
matters...as you say, the phone wires are a pig.

What I did seems pretty neat and works nicely. Designate 4 or so ports on a
patch panel for each incoming phone line. Run a CAT5 from each master
socket's extension connections to the patch panel, daisy chaining through
the 4 ports. You can then make any patch up to 4 sockets onto any one line.

To keep things simple at the other end, I used plain BT face plates where
only a phone was ever likely to be connected, but still ran two lots of CAT5
to it, such that it could be swapped for a double RJ45 plate if desired.

Bad move, this knackers the RJ45 socket (the plastic bits either side of
the RJ11 terminals bend the outer RJ45 contact wires). Or at least it
did when I tried it.

RJ45 socket to fit in the BT socket so I can then patch to the panel. Do

At the phone end, I used secondary RJ45-BT socket leads like you have
found. At the phone line end, I used the same, with a male to male phone
plug lead obtained from www.netshop.co.uk.

For the patching, I had a patch panel larger than required for all the
connections. Then I chose 8 patch sockets (all the highest numbers) and
using some stripboard and some cable ensured that the pins were all commoned
together. This allowed short 50cm patch leads to patch a particular RJ45
socket into the phone system, including the one that led to the incoming
phone line. By not hardwiring this, it allowed any socket to configured as a
phone socket (by patching to the commoned area) or a computer socket (by
patching to the hub).

Secondly to connect my broadband router to the patch panel I'd like a RJ11
to RJ45 patch lead. At the moment I'm doing this with a two leads and a
RJ11
to BT coupler connected to a BT to RJ45 coupler.

That should work.

It's tinsel. However it's a long while since I saw any line cords in
tinsel, probably too expensive, they tend to just use quite fine copper.

Tinsel is what Stefek was referring to - 'tinsel conductors' being the
phrase used in specifications for this sort of wire. It can usually be
soldered with a little patience, but the joints never look very pretty.
Heatshrink sleeving can cover a multitude of sins though...

That's the word. Haven't seen any for years...last time was probably on
the microphone lead of a 19 set...

They do exist as I liberated such a cable from a skip at work but I've
never found anywhere that sells them.

Convention is to use pins 4 and 5 (the blue twisted pair), since this is
unused in Ethernet*. I believe the original intention was to allow
network and phone service to office desks with one patch cable.

(* yes, I know gigabit uses all 4 pairs.)
