How best to wire up a BT extension to an outbuilding?
Posted by Bypass on October 21st, 2006


I would like to take a wired telephone (and broadbroad) extension across
to an outbuilding, which is detached and about 100m away from the main
house.

Could someone please suggest the best way to do this?

if the broadband is to be used at both ends a point to point wireless
link with external antenna may be the best solution for the broadband
component. If you want a wired phone then 100m of external grade
telephone cable or use VoIP on the wireless link.

if you want to "share" broadband with the house, then it probably is best to
put a broadband router in the house, then link the building using some
flavour of Ethernet

cheapest way is "just cable" and 10 or 100 Mbps - 100m is in range.

but - you need to run the low voltage cable separately from the power (for
safety - not an interference issue)

a POTS phone will work fine over Cat5 (run a couple of links as you always
seem to need extras - burglar alarm?)

if you run power there from the house, powerline extenders may be the way to
go for the network if you dont want a separate cable run. If you need
wireless then plug in an AP (or use the WLAN on a powerline box - -see
below)

not used these, but they seem popular:

Go to Maplin and buy some 4core screened cable. Clip it to the wall OR bury
it in the ground encased in a garden hose! Tape the ends of the hose with
self amalgamating tape and cover in insulation tape. Then you can bury the
cable. Or you could use the more expensive plastic conduit and appropriate
fittings.
Wire one end to a new socket and the other into the back of your master
socket. You could also connect the screen to an earth point in the house.
It's mainly down to using your imagination a bit. Only 3 of those 4 wires
will be needed by the way.

NO, NO, NO...!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!

NOT ordinary cable, even screened, EVER..!!!!!!!!!!!!!

Telephone cable must be a twisted pair; use CAT5 then you can use 4 wires
for an Ethernet link and three of the remaining 4 for the phone.

Thanks for the responses so far.

The outbuilding is, in fact, a refurbished barn. Like a lot of property
in Cornwall both the barn and the main house have massive stone walls
(450-600mm thick) and coupled with the fact that the two buildings are
100m apart, I didn't think that a wireless solution would work that well?

BT have quoted the standard £120 for a new line to the barn, but that
simply duplicates the monthly charges for line rental and broadband.
They also quote around £100 to take an extension from the house to the
barn, but I assume that won't help with the internet access if there is
a broadband enabled PC in the house?

There is a domestic electricity supply to the barn from the house, so
the Powerline solution is worth pursuing. This won't bring in a
telephone line, which means that I'd have to rely on VoIP. Since this
is now a broadband/VoIP issue, I'm going to start a new thread in the
appropriate groups.

Yep use CAT 5 the brown pair aren't used for 10/100 and can carry the
phone line "after" its been filtered..

Do it like this..


The incoming phone line in the main house goes into a NTE5 faceplate
this separates the Phone one way the Internet the other. Connect to the
Internet side a ADSL modem router one that has a few network sockets on
the back of it most all of them do these days. The Linksys range are
very good.

Run Two lumps of CAT 5 to the barn, You could if your crafty use the
Brown/white pair to carry the phone on if you want but cat 5 is so cheap
its not worth the bother.

Take one of those sockets via a ready made patch lead to the CAT 5
socket, you can get these from most any electrical wholesaler. Get a
roll of CAT 5 cable run that to your outbuilding punch down with a Krone
tool the cable to the patch socket near the router and at the barn end
keep the socket wiring as short as possible and maintain the twists in
the cables..


At the barn end terminate the cable on a CAT 5 outlet and connect that
via a patch lead to whatever bit of computer gubbins you want to at that
end, and if you need more than One get a cheap 10/100 switch and plug
the other stuff into that as well as the patch lead from the socket you
have from the house.

On the other bit use the Blue/white pair to connect to pins 2 and 5 of
the NTE5 wallplate there is a facility there to connect extension phone
wiring to Use any other single colour to carry pin 3 on leave pins s 1
and 6 unconnected. Do the same to a slave phone socket at the barn end.


CAT 5 is a very good inexpensive cable for these sort of applications
and whilst it is a bit more time consuming to install its far more
reliable and secure than wireless links at those ranges unless you have
external aerials etc..

You now you have a net connection as well as phone, you can use the
ordinary phone and VoIP, best of both worlds!.

There are quite a few websites re CAT 5 wiring and phone wiring "how
to's"...

I've done this underground for about 60ft and it does only work when
twisted.

But what I don't understand is, the old fashioned self supporting grey
figure of eight cable was obviously not twisted. Yet a friend gets perfectly
good broadband with that (he's fussy about the speed as he's a gamer). But I
think it's still in use? And when the BT engineer called recently he
certainly didn't offer to replace it.

Don't know about the modern 2pair back covered though, is that twisted? If
not, why not?

Twisted pair is important if there are noise sources close to the cable.
There aren't, if it's in mid air.

If you aren't using the broadband in the house, just carry
the unfiltered phone line to the outbuilding and put the
ADSL modem in there. Broadband covers distance much better
than ethernet does.

Don't share phone and network in same cable. Lay separate
cables -- cost of cable is insignificant compared with effort
to install it. I would even go so far as suggesting you lay
at least a spare Cat 5 for which you currently have no use,
to allow for expansion or a new service in the future.
You might even consider using Cat 6 cable over this distance,
which will provide more future-proofing.

Also, if you are running 3 conductors for the phone, you lose
the benefit of twisted pair and there isn't any twisted triple.
Pass just the A and B conductors over the run (contacts 2 and 5
on the BT phone socket), and fit a master socket at the far end
to reconstruct the bell wire in case you ever use a phone which
requires the bell wire.

I assume that you're referring to the sort of replacement filtered faceplate
which you can get from the likes of Solwise or Clarity - rather than the
standard BT unfiltered offering?

I think most filtered faceplates now provide the ability to krone digital
extension wiring into the back, but some of the early ones only had an RJ11
socket on the front for the ADSL connection, so this is something of which
the OP needs to be aware if going down this route.

Now let me get this straight. On the BT standard Master socket NTTP box
your saying that even with the addition of the filtered faceplate the
one marked ADSL V1.0, that the extension krone strip where you normally
take phone extensions may NOT be filtered?..

Not quite. It's that there is no Krone connection for taking an
unfiltered feed from the back; only from the RJ11 on the front. The
original BT one is like that. I have one. It doesn't bother me, because
the rack with the router in it is 50cm from the master socket.

Note the point about "some of the early ones" above. I don't know
whether BT still supply those, or whether it's what BT always supply
themselves (if they supply them at all).

No, that's not what we're saying.

AIUI, *all* filtered faceplates have a filtered BT socket and an unfiltered
RJ11 socket on the front, *plus* a filtered krone strip - for analog
extension wiring - on the back.

In addition, the 'modified' faceplates from Clarity and the latest ones from
Solwise *also* have krone connectors for (unfiltered) digital extension
wiring on the back. This is what the OP needs if he wants to run a digital
extension from the master socket in a neat fashion.
