Creating a filtered an unfiltered extension on same line

[newbuilder]

Hello,

I have managed to create an ADSL extension and telephone extension at home but now it is time to do the mother-in laws.

So this is what I am thinking, tell me if it works:

Put an ADSL Nation filtered face plate on
Run one cat 5e cable from this but use the wires in the cat 5e cable to take a filtered and unfiltered line to an extension socket
Fit an extension socket that will have a phone and ADSL face plate (All in one) that will have no filters in it as the phone will be filtered at main socket.

will this work or will i get interference as the filtered and unfiltered are running down the same cable, all beit in separate wires?

Also anyone know where to get cheap cat5e? I reckon I will need quite a bit of it. Still to measure it though!


thanks

Yes that will work, the isolation between the pairs will be fine. Don't forget to run a ring line as you will have no filter at the other end and your phone may not ring without it.
Suggested pairs.

DSL= Green pair.

Voice (filtered) = Blue pair.

Ring line = Orange with white rings.

If you are pushed for cost, then 3 pair CW1308 would work just as well and is a bit smaller.

Thanks Brian any idea where I can get this equipment at a decent price.

Clarity seem to do the extension box I need but it is £6.
ADSL main filter is always a little expensive so I know I have to pay for that, after all it does all the work.
And cat5e? Any ideas where it is at a good price?

Don't know where to suggest, trouble with trying to get cable at a low price is that you may have to buy a large amount. Bite the bullet and try Maplin.

I think you are over complicating things, all you need do is run one unfiltered pair to the extension and fit a filtered extension faceplate.
