Full fibre connection existing internal copper network

[Peterhcee]

I have a copper telephone network in my house. I have a standard telephone outlet in every room in the house. I most rooms there are two telephone socket outlets. The master telephone socket outlet is in the entrance hall near the front door. The wires then go to an external connection where BT connects the telephone and broadband service. My office is on the first floor and my Hub is connected to the broadband via one telephone socket outlet and my telephone is plugged into the other telephone socket outlet.  I get a good WiFi signal in every room in the 3-story house. I am upgrading to full-fibre with digital voice but wish to keep the internal copper network energised and my office on the 1st floor.

Can BT connect the full fibre cable to the existing copper network so I can maintain my Hub and office on the first floor and use any telephone socket outlet to plug my phones into various rooms?

Search voice reinjection on how to incorporate your copper wiring extensions into your FTTP with SH2 router , this is your responsibility, the FTTP installer won’t do this for you , the work involved will depend on where the FTTP ONT is located, basically the extension wiring will need to be redirected to connect to the router and needs to be  disconnected from where the copper cable enters the property, it’s not beyond an competent DIYer , but a tradesperson could probably be found to do this if that’s easier, but it’s not Openreach or BT ‘job’ to do this .

Firstly your internal wiring is your responsibility not Openreach's, so you will have to make the changes yourself. Openreach will expect the ONT and hub to be co-located.

There are two things you will need to do.

First you will need to run a Cat 5e or better Ethernet cable from the ONT (Optical modem) to your hub assuming that Openreach won't be able to site it adjacent to your hub on the 1st Floor.

Second, you simply need to disconnect the incoming copper wires from the master socket and then connect your hub's green phone socket to the extension phone socket using a double ended BT431 lead.

Could you put that in plain English please by defining the multi letter anagrams you have used?

Why can't I connect an ethernet cable from the optical modem to the master telephone socket?

Not having a hub on the 1st floor would not deliver WiFi to the whole house as it does now.

I already did.

You can't connect an Ethernet cable to a phone socket. You need an Ethernet cable from the ONT to the hub, not a phone cable.

Distributing the phone signal from the hub is simply a matter of connecting the hub phone socket to any convenient existing phone socket. But you will need to run an Ethernet cable for the broadband.

My current hub is connected  by ethernat cable through a ADSL filter to the phone socket. 

So why can't I juste repeat that, connecting the ethernet cable from the optical modem to the internal copper phone network?

No it isn't. It is connected by a DSL cable which is only 2 wires and totally different technology to Ethernet which is 8 wires.

It would be akin to connecting a gas fire to a mains socket, it can't be done.

If you really are unable or unwilling to run an Ethernet cable, it is possible to connect the ONT to the hub using powerline adapters which use your mains wiring to carry the Ethernet signal. The speed you will obtain using this method will be dependant on the quality of your mains wiring.
