FTTP - getting to the CSP box

mwwagain — Tue, 03 Dec 2024 18:34:48 GMT

A query on 'how its' done'.

FTTP is imminent (chat to the OR quality guy checking the street installations) and my property is fed underground from a chamber in the verge. There is no external cabling - it comes up through the concrete slab under the house, into a plasterboard wall to the master socket.

How do they deal with those - and do they even know such detail? Is that the kind of thing that fouls up installations ?

Can you have an internal CSP, or do they have to dig about outside until they find the duct and break into it ?

TIA

Others may be able to explain this better, but my understanding this case is that the FTTP cable is fed in exactly the same way.

Yet the 'how we do it' videos I have watched show an *external* CSP box, even for underground feeds, and most of the pictures look to have new ducts, implying it is 'required' in some way.

Again, others may be able to give more detail, but the feed from the chamber will utilise the existing duct, the CSP will be attached to the external wall, and a small hole will be drilled through to the internal wall, where the ONT will be fitted.

Run the following and look at what it says about the FTTP install (assuming WBC FTTP is shown in the left hand column). The narrative may give a clue.

OpenReach may have to do some digging outside your property to bring the cable up out of the ground. Usually you won't find out until the day of install.

We have not yet got to the stage of having an entry there - still shows ADSL only until the paperwork clears or more precisely that the Scot R100 programme have to pay OR before OR will release the 'can order now' flag!

Was hoping someone with a similar build would have had an instal so I know what to expect - and whether to have a little dig myself beforehand to keep things tidy.

That would be the wrong side of the wall.

Duct comes up **INDOORS** - hence my original query about digging

Using the duct all the way they'd either need

no holes (internal CSP where the existing master socket is, CSP to ONT on existing internal wiring hole)
or
two holes (out from duct to CSP, then back in from CSP to ONT where there's power)

Fair enough, @mwwagain . From your description of the current installation, I'm guessing yours will need a survey to determine the best route, but if as you say OR have already been looking at things, this will be fed back and they will have an idea of what they, possibly, could do.

Yes, you can have an internal CSP, or at least it was possible when I had my FTTP installed several years ago. A different situation to your underground duct, mine was through self installed conduit for an overhead feed entering the house under the eaves and finishing in a downstairs utility cupboard. At the time it was the blown fibre method.

Depending on when the property was built there might not be a duct, our telephone cable was directly buried.

An Openreach engineer came and we agreed a route from the pavement to an agreed location for the entry hole. A dig team turned up a week or so later and installed a duct plus a draw rope ready for the second stage of installation.

It should be a duct. Next door (also 1993) has a suspended floor and their duct comes up in the middle of the house footprint

Was reading installation guides for FTTP recently. One of the key points was that ducts to the CSP must be external to the property to avoid the risk of ground gas being conveyed into the property. There’s also the consideration of the same being an access route for rodents.

If they do a survey first then hopefully you'll be there and able to chat about what's actually going to be done.

Note that the internal ONT does not have to be in the same location as the Master Socket. It does need power but if it's possible to put at a desired location the installers usually play ball. They won't go through the house but the same room in which the cable comes in is fair game. They might also be willing to run external cablle round the house, tacked to the wall.

The router is conencted via ethernet cable so can go anywhere you're willing to run said cable.

At the end of the day you won't know until OR turn up to do the survey or install.
