I'm getting VDSL installed this week if all goes to plan.

My question is regarding the location of the splitter. I have an ADSL2+ capable splitter but it is not in the ETP. It's halfway through the ceiling on the end of several metres of wiring at least 30 years old. From there it goes to some UTP "Homelan" to the DSL jack.

The old wiring in question is thick, black, flat and definitely not twisted-pair of any kind. I assume it will not help, but I don't know. If it does, how much does it matter?

Should I ask for that wiring to be replaced\bypassed or is that standard practice for VDSL installs? I don't know why the previous technician chose the spot he did for the ADSL splitter except probably for ease of installation.

Hi, the exact location of the filter can go in other locations, but the critical issue is that the line at any point does not split of tap off to other legs before it gets to the filter, and once out of the filter the modem side is not ever split but only goes to the modem. what happens to the voice side is of no concern.

However you describe a section of trurip cable (thick non twisted heavy cable) this really must be replaced with modern UTP cat3/5/6 etc.

Yup! Definately. Something about impedance and physics and stuff.

Thanks, that's what I thought.
