I moved into a brand new house and the electrician has installed the standard (old) Telecom BT jackpoints (NZ Master socket?) in the walls for telephones. I want to use these wall sockets for connecting Cat5/6 cables. I do not have a Telecom copper line coming into the house. I have fibre only. Where can I buy an adapter? It will be BT male to RJ45 female. These wall sockets run back to a hub in the garage where I can connect my modem using Cat patch cables. I think this is right. Is this possible?

Nope. If the sparky has used cat5e or cat6 cable you will need to get rid of the bt sockets and fit RJ45 sockets.

BT jacks for analog telephones often only have 2 wires connected. That's not enough to run a network connection. You need 4 wires for 100mb ethernet and (6 or 8) for gigabit ethernet. You might have to change the jacks. I woudl take one off the wall and check the house is wired with CAT5 or CAT6cable with 8 wires in it. If they have used cheaper 4 or 6 wire phone cables through the walls you won't get ethernet running over those cables.

Why oh why are BT sockets still being installed in new houses!?
The crazy thing is they cost a lot more than RJ45 sockets!

I went on site to a customer today too, they had just moved their business into a newly fitted out building, and they also had BT sockets everywhere!

As already stated you will need to replace the BT jacks with RJ45 as the BT sockets will only have one pair punched down.
BUT no point doing that if they haven't used CAT5/6 cable.

Edit: Can you post a photo/s of the patch panel so we can see what has been done in there?

Opinions are my own and not the views of my employer.

Following on from Dynamics reply - BT jacks are not suitable for local data connections - unscrew one of the face plates and look at the back - only one pair (pr) will generaly be connected (blue/white) if there is ony one cable connected and it also 3 other prs (orange/white, Green/white, brown/white) then you are probaby in luck to reuse the cable for data, the BT can be replace with an RJ45 jack at that end.

You will have to do the same @ the other end - this will be more than likely be a twist join of all the Blue/white prs of all the cables to the BT jacks twisted together - you need to identify which cable is the one you need and put a RJ45 jack on the end of that.

Not to hijack the OPs thread - i have to deal with this situation daily with single BTs installed in new homes and no hub at the other end, just a mass join in the ceiling - the worst still is yep its cat5 but series wired on may be 2 or 3 BTs and the new owner was told when they were buying that it was 'ready for fibre' &%$#&$.

An example I came across today is a new student flat (less than a yr old) 6 individual rooms, 2 bathrooms, common lounge and kitchen - only cabled for 2 BTs one above counter top in kitchen and one in the same wall (end of house) of the lounge , series wired from the ETP @ the same end - and nothing in the rest of the rooms and they wanted a new fibre connection some where near the midde so they could shear it from a router on the floor in the hallway with long patch cords into each of their rooms.

Some Developers realy dont get it that a couple of BT jacks isnt enough and that it doesnt realy cost that much more to cable and fitout a building for data.

Yes our new house, which has a hub in the garage, has only three BT sockets in the house. One in the Master Bedroom, one in the pantry, and one in the formal lounge. Nothing in the Family/Entertainment room, or the other three bedrooms/studies!

Perhaps it is time that the telepermit for any BT jack was revoked making them unavailable in the market for these cheap-ass electricians to install?

That looks like not-too-badly-wired Cat5 cable to me. You should be able to have the BT jacks changed to RJ45 without issue.

But what did you order when you had the house built?

I know people that ordered "smart wiring" from the builder and just had more phone sockets and RG6 reticulated back from the main TV as the result.

Looking at your latter photos, looks like your developer / builder / sparky was only 65% useless. Go to the expense of buying a distribution cabinet, patch panel and only runs 3 wires and then put BT sockets on the other end! It would have been so very easy to run more cables at that time. Some people just have no idea.
Could be a lot worse though. At least, from what we've seen, you should be able to have 3 network outlets throughout the house. They could have run just 1 cable and daisy chained it.

Edit - lower value from 65% useless to 50% useless due to at least being able to run 3 network connections. Then again - "Nothing in the Family/Entertainment room, or the other three bedrooms/studies! ". Nah - it stays at 65%.

Yes. All three of them!

All installed by some sparky who knows nothing about data cabling?
