hamish225: so, how do i tell what kind of wiring my house has? our house is 14 years old, would i have good wiring?


You're likely to have cat3 phone cable wired in series (daisy chained from jackpoint to jackpoint) and probably old 3 wire BT jackpoints rather than the newer 2 wire ones.

"Good" can mean a lot of things but your setup is probably not delivering your optimum ADLS2+ speeds at present unless you have a master filter installed. There is no easy way to answer that question for you.

pull a telephone socket off the wall.
Behind it you will see the wires going into the plug. See if you can pull it out a bit from the wall - the installer should have left some slack cable.

If the cable has 4 wires in it - you have old cable.

If the wire has 8 wires in it and looks something like this, you have new cable.
That text on the outside cover will hopefully say cat5e enhanced UTP or something like that - the text is up to 30 cm long so it should be in it somewhere.
So the telephone wiring on a cat5 cable is usually the blue, and the green, orange and brown are usually left wrapped up behind the plug nice and tidy.
If the orange and green pairs are not being used, you can use them for standard 100mbit data and put on an rj45 plug for your computer. If the cable goes where you want it.


At 14 years though you will probably find its just older 2 pair (4 wires total) in the cable, but the cable will be in good condition for vdsl or general adsl. It was really only in the last 10 years that cat5 cable came down to rock bottom prices that builders started using it for telephone and alarm wiring instead of the general telephone cabling because cat5 is made in bigger quantities and is a higer grade of cable than what qualified for telephone.

Didn't MM Cables use Cat5 twist pairs in their Telecom 2 pair cable?

yeah it looks like two pair cable connecting to a BT socket. Daisy chained, as one pair coming in and a second pair going off to another BT socket somewhere around your house.

How many extra wires are there? I was guessing two extra wires (from looking at the photo). The extra wires equals 1 pair. The extra (currently unused) pair is for if you wanted a second telephone line. They are surplus to requirements if you only want one line.

If there are 6 extra (unused) wires then you have 4 pair cable. Once again one of the extra pairs (usually orange) is used if you want a second line. The other two pairs are not used with a telephone. They are used for obtaining GigE speeds over home network etc as in a structured wiring install.

ahhh, so if i so desired, i could put in a 'network plug' by each phone jack in my house and I'd be able to have a proper wired home network?

You need all 4 pairs to be connected on cat5e cable to be able to achieve gigE speed in a home network.  Assuming that you have 4 pair cable in the wall, you are still using 1 pair for the telephone service thus you only have 3 pair available to connect to a RJ45 jack (or 'network plug' as you have termed it). 

You can achieve 10/100 ethernet with 2 pairs connected.  refer here

If you have only one pair left then you are out of luck.

If it's twisted pair cable then it's possible but you're looking at a maximum of 10Mbps for cat3 cable.

If it's not twisted pair then data use isn't possible.

sbiddle: It's not just for FTTH deployments - it also contains a VDSL splitter so can be used in place of an existing central splitter.


To what advantage? 


its a VDSL splitter with batteries!

jk.


not a verry useful device AT THE MOMENT, but in the near future when everyone has fibre instead of copper wires going into their houses this will actually be of some use.
I think it is going to be SLOWER that what we will have then, because I hear flying pigs transfer data faster than this thing

This story has slowed even more now only  "up to 50 per cent" ( or 100+ times less than this morning)

Still thats double the waste !!  Telcos need to think GREEN and not supply endless wall decorations that serve no real powerful purpose.

Check out the FFTH backup power supply debate at this thread

The real issue is not about speed but how to power the ONT during power outages

Yes, and I have successfully run Fast Ethernet (100Mb/s) over that cable, which I should point out is not the same as the 3pair cat3 cable in the photo by hamish225's on this page which will only do 10Mb/s
