Since there appears to be a few cablers around here, I've got a question.

In an older house, where the termination point/demarc point of a phone line is the first jackpoint of the house, at what point can the owner make changes to the wiring.

Essentially, what I'm thinking is, installing a fixed ADSL master splitter in the first jackpoint, & doing a Cat5e cable run from the jack to a new RJ45/RJ11/whatever the new standard is, jackpoint for an ADSL modem (plus perhaps a standard jackpoint as well).

So, is such a change 'legal' and could it effect the Telecom Wiring & Maintenance 'insurance' that we get? Alternatively, what's the best way of getting this done 'professionally'?

I'm just curious at this stage, plugging the ADSL modem into the master jackpoint doesn't provide much different in sync stats etc, but I think it'd be a good thing to do none the less.

Have you identified the demarc point on the outside of the house?
It is usually at the point where the telecom wire touches your house coming from the street.

I think what he is asking is can he put the splitter in the Demark, or is that a no go area from telecom.

He's identifed the demarc - being an older house, it's the first BT jackpoint in the daisy chain.

Spot on, 2nd stanza of my original post.

As far as Telecom/Chorus has been concerned, that's the demarc point, it's the first place they look at if there is a fault, and I'm not aware of any other entry point into the house.

I know in the UK, they have the newer NTE5 boxes that clearly show what you are allowed to touch, and what you aren't allowed to touch, but it seems a bit cryptic here.

My understanding (and I'm open to being corrected!!) is that you can touch whatever you like on your side of the demarc.

Seperate to that is Telecom's wire maintainance charge, which if I understand correctly prevents you being charged when a technian comes out to investigate a fault and discovers that it is on your side of the demarc (as opposed to Telecom's side).

Okay, that was my understanding too, but as the first box is the demarc point (well specifically the wires, am I allowed to touch said wires to wire it into a master splitter my un-educated guess would be no - also to me, this means that I couldn't even replace the first BT jack because if I'm not mistaken, the Demarc wire is crimped directly onto part of it. Gets confusing.

I don't think Telecom will complain if your master filter has a telepermit and is installed properly, but check whether your upgrade involves dealing with different guages of wire on a 3-wire master jack, in which case you might decide to replace all jacks in the house or even go all the way with Cat5e star wiring.

Time to find a new industry!
