Hi,

does anyone know of someone who would install a ADSL master splitter on the shore.  My Demarc point is right on the peak of my roof and beyond the reach of my standard ladder, so I figure by the time I hire an extendable ladder I might as well pay someone to do it and I don't have to worry about falling of the ladder.

Or can the master splitter be installed on the other side of the wall in the ceiling cavity?

I would expect that it be installed inside your house. In the roof space behind the demarc should be fine. They don't look very weather proof to me.

Chorus would be a good start - i think the charge is $150 and includes wiring the new jack for your modem

I got up ito the ceiling today to work out where the cable came into the house and where the easiest place was to get the cable from the ceiling to the garage where the router will be and having to watch where all the HRV ducting was got me thinking, will the ducting or the HRV motors give off any interferance I should avoid in order to get max connection speeds?   I'm planning on just using standard Cat5e cable.

I got into the ceiling today to have a closer look at the wiring and didn't quite find what I was expecting.  I was expecting 1 solid looking cable coming into the house that I'd connect the master splitter too.  However there were 2 reasonably solid looking cables (pic 1 pic2 ) coming into the house and then connected to some cable that looks like speaker wire or something (pic) via a standard electrical terminal block.  So one of the black cables connects to one side of the cable going to a phone jack and the other black cable connects to the other side. 

So what are the 2 black cables coming in for and how should I connect that to the slitter?

Thanks

We might need some better pictures inside the attic.

The cable should come in, and in an older home, it will go straight to the master jack.
From the master jack, it will then go to your other jacks.

In a newer home (mid 80's) it will probably split in the roof and go to the various jacks.

In a new home (2009+) it will probably go to a master patch board in the garage.

If you can show us photos of where the cables go once they come into the roof, we might be able to work it out. It is possible that one cable has been damaged in the past and a new one put in place, or maybe you had 2 cables carrying 2 lines. You can just test this by plugging into each jack in the house and see if any dont work when you try to call out.

There is only 1 line running through the house, and thats the line I mentioned that looks like speaker wire (its the white looking cable in the pics).  It runs through the ceiling cavity down the inside of a cupboard to a normal phone jack ( pic1 pic2 ). From there, there is another cable (the grey one in the pic) daisy chained to the garage where it goes off the other jacks in the house in a star formation (pic) again using eletrical connector blocks like this .

So I would have thought both of those black lines coming into the house are live as they only connect to one side each of the cable going to the first jack.

Yeah id say both the black coming in are your pair. Thats quite old school - normally you have a single black with a small coloured pair coming out from in side.

You'll want to run new cable (your cat5) from the black cables to the garage and install the splitter there. Use gel crimps like these http://www.tradecctv.net/images/3wire_gel_crimp.jpg

Does your splitter have 2 or 3 pairs coming out of it?

While the black cable coming in was standard some time ago, i dont think the white cable was ever standard, so combined with the electrical connectors id say it was a dodgy diy job.

Suprisingly you can still get reasonable speeds over that kind of black wire - we have it running from the demarc to the main phone jack and sync at 20mbps adsl2+. But i understand its best to get rid of it and replace with cat5

I'm waiting for the splitter to arrive but looks like it has 3 pairs coming out.  Why install the splitter in the garage?  I thought it was best to install it as close to the demarc as possible and then run cat 5 to the master phone jack and ADSL jack?

20Mbps, I'd settle for even half that, I only get 2.5Mbps on a good day at the moment.

Sorry, i might have misread you. Put the splitter at the first jack, wherever that may be. Or if you can fit it in the external termination point the do that.
Correct, closest is best but if your're replacing all of the wiring from the ETP with cat5 then there will be negligible difference.

Right, it should look like this one
http://www.trademe.co.nz/Computers/Networking-modems/Other/auction-289723981.htmhttp://www.dunamys.c...

From the orange/white pair, connect one to each of the black incoming cables (or if you are going to run cat5 from the end of the black pair to the splitter located elsewhere you might like to use the orange and white pair in the cat5 cable to keep things simple)

Green/white pair goes to the modem jack
Blue/white pair goes to the rest of your phone jacks

Cool thanks for you help. 
The 2 black cables come into the house from the demarc point on the outside of the house so there is probably only about 500mm of that cable so I'll just remove the electrical connector block remove the white cable and use the gel connectors to join the black cable to the splitter then run cat5 to the 2 jacks.

I'd love to know what results you get after you've finished. I'm part way through rewiring my house and adding data, replacing all the old phone cables with cat5e. I jumped from 2.5 Mbps to 9.5Mbps, and that was just taping a the ends together with electrical tape!

Yeah I've been watching your thread and saw the jump in speed, hopefully I'll get something similar, I'll let you know how I get on.

Puts the chorus claim that 80% of NZers will be able to reach speeds of 10Mbps by end of 2011 through cabnetisation into perspective. Theres a lot more work to be done!
(Im not criticising chorus, its a broader issue)
