I need to know how I would go about finding out if my wiring is daisy chain or star. I want star wiring since I am planning on getting VDSL soon and there is no way I can get it wired to where I want if it's daisy chain without having exposed cables through the house. I did look into how to tell if you have star wiring and I don't have a star wiring box or utility box that has cabling going to it. Is there a way of telling if it's star or daisy chain. I will also have to locate where all the cables meet up if it is star.

Info on my house:

 

  • I can't have a new cable wired under the house since it sits on a concrete slab. It would be confusing if I described my house so just trust me when I say I can't have it wired without exposed cables or plastic covers on several walls.

 

  • House was built about 5 years ago, 2007 (not by me).

 

  • I can plug my modem/router into any jackpoint and it works and the jackpoints only have 2 of the wires from the cables joined to the socket (don't know if this helps). I don't have multiple modems so I don't know what happens if I plug in a second one.



I can't get someone out just to see how my house is wired since an ISP wont pay for that and I don't want to pay for it either. I do plan on going from Telstra/Vodafone over to Snap, I might not change though if I can't get VDSL wired how I want it so that kind of makes things difficult.

From reading other posts I can see everyone suggests the coffeebaron to look at things like this but I don't live in Auckland.

You will more than likely have daisy chained jacks although the methods can be mixed. You can easily check this by undoing the faceplate. Expect to see 2 cables connected except for last one. Any with more than 2 is a star point. Unless you have an external test point/junction box one of the jacks could have 2 distinct cable types. That will be where the network joins to the internal wiring.

Simple answer is to take off the face plates of your jackpoints - only 1 cable in each = Star / 2 or more cables attached in each = daisy or a combination of both

being able to plug your modem in at any jackpoint, and you still get ADSL, indicates that you dont have a master spliter installed


Judgeing from the age of your house it would either be cabled with 4 pair cat5e or more than likely two pair 'homelan'.  So even if your house wireing is daisy chained and new cabling can't be run, providing there is a good spare pair in your house cableing, then it can be manipulted to provide a dedicated point for xDSL service.

If you have star wiring the master filter would be located within the ETP and the VDSL signal reticulated around the house using a spare pair of the existing wiring. This is done by simply joining the second pair with scotchlok connectors at each jack before the one where VDSL is required. At that point a new jack would be positioned next to the existing one.

Hey InstallerUFB - minor stuff but suggest some wording changes for you:

I have looked at 2 jackpoints and they only have one wire. So I guess I can turn any jackpoint into the dedicated line.

hamish225: with mine they ran the cable up the side of my huse, into the roof space and then down a wall into a closet.

Yup thats a good way to handle a concrete slab, if you can get into the roof at that point.run the cable down the corner of a wall and along just above the skirting to where you  need it.

You should be able to find a hatch or cover plate on a wall somewhere that has a "110 punchdown" block inside it. You could change this to a small cabinet with a patch panel, master spitter and modem inside it. You will need to wire together the blue/white wires of all the outlets that you want shared on the same phone number.
