hey,
I'm not sure of a few things so, hopefully you guys can help :)

what i need is a splitter (not a filter as well) I'm not sure were to get any from and i don't what to get telecom to do it they have messed our lines as much as we need already.

for people wondering i need a splitter for the line because we have a very bad lines
(the house was DIYed and has one line using 3 separate cables coming out into the house)

and second if its best to run cat5e or just to use normal telephone lines for the router?

a lot if this is needed the connection is a ihug max/160kbs connection and i get usually about anywhere between 320/64 and 64/64 i have seen some of the line has a lot of joins in it so i have been talking to a friend about it and he also says that a splitter would be good to isolate all the very bad wiring

There are only filters, splitters are simply filters with a output connector on both the input and output of the filter.

As you will find in other threads the aim is to intercept the line as close to where the cable enters the house. At that point (before it is connected to any phone points) install a filter, connecting all the onward phone lines to the output, and take a direct run from the input of the filter to the ADSL modem.

Cat5 or 5e is good, as is cat3 (white phone cable with two twisted pairs inside) but dont use flat line cord except for purhaps the last 500mm-1m from the wall socket to the modem as this is incline to pickup noise.

If you are not confident in doing any of this then get a professional installer to install a proper central filter.

so are you saying to use the normal adsl filters and pull it apart then use  that as the splitter?

To clarify a little:

'filters' are usually plugged in to a jackpoint with phones then being plugged into them.  The advantage relative to a splitter is their price and ease of installation.

'splitters' are installed to the incoming phone line (usually at the point of entry) with the filtered output going to all the existing jackpoints (where phone devices can be used as normal) and the unfiltered output going to the ADSL modem (usually via wiring to a new dedicated jackpoint).  The advantage over a filter is quality - the splitter is typically much better as a filter and better 'insulates' the ADSL modem from interference from phone devices and therefore faster and more reliable connections are achieved but the disadvantage is price and installation cost.

Both devices provide filtered output to phone devices.

Most people dont have the skills or tools required to install a splitter - so they are typically available only in trade outlets.

Yes sorry should have clarified my post, a central splitter can be obtained from electrical wholesalers, or online here. By placing this at the line entrance to the home you will isolate all the house wiring from the ADSL signal both in terms of line loading that phones/faxs place on the line at DSL frequencies and reflections due to all the spurs of phone cabling in the house. This last aspect cannot be achieved by installing micro splitter/filters at each phone jack and is very important when on a long line.

You will find that any work people have done on the phone lines at your place will be isolated (at the ADSL frequencies) by the adsl splitter, so its probably worth getting Telecom to do that. They will install a dedicated adsl jackpoint near your modem.
