I was planning to do something like this...

But the question is...

1) Will it work?

2) Do I need anything clever at the wall socket end for the telephones?

When I used to wire buildings we needed modtaps to make the phones ring over structured cabling because they were coming from a local PABX.

But if I all ready have voice 'under the stairs' because I've used a microfilter, can't I just use dumb RJ11 to RJ45 convertors?

Thanks

If you plan to use the same number for voice calls as your broadband is running down, your schematic should be OK.
Plug a triple adaptor onto the voice side of the microfilter and use (as mentioned) RJ11 TO RJ 45 or PSTN to RJ 45 leads to patch to rooms.
You will need a PABX master modtap / balun adaptor at phone end.
try www.minitran.co.uk
for some nice cheap prices.

Thanks for the reply :thumbright:

One question please (and I'm asking to learn - not to argue :wink: )...

If right now I can plug my phone directly into the microfilter and have it work OK, why do I need a balun at the far end of the UTP?

I thought providing all the cores matched up as it goes through the UTP it would be treated just as a normal extension lead.

At work (and this is 7 odd years ago and the memory ain't what it used to be) I remembered we needed the Master modtaps to make the phone ring (something to do with a capacitor)

Right now I have a 20 mtr std BT extension kit running from the microfilter to the bedroom with the phone plugged into it. I'm fairly sure it's just a dumb extension and it works OK. Isn't this what the UTP would also be doing.

Sorry if I'm missing something obvious :?

Thanks
