Internal house phone wiring/extensions after FTTP installation

I am shortly due to receive an FTTP installation from BT, having had a copper ASDL connection from another provider.

I currently have an overhead copper line, and understand the copper line will be replaced (yes??) with a fibre cable. It will be able to enter the house at the same point as the existing copper line. 

Currently, in the house, we have three wired extensions running from the existing master socket. Does the copper wiring for these phones simply get connected to the new BT Optical Network Termination (either as one line which is then split, or as three lines??). Can we use the existing house extension wiring? And can we continue to use the existing (fairly modern) phones? 

Or, heaven forbid, do we need new internal wiring and new phones? That is the last thing we want (old house with two foot thick internal and external stone walls).

Any advice or experience would be appreciated. Thanks in anticipation.

Re: Internal house phone wiring/extensions after FTTP installation

One of 2 things will happen and I very much suspect it will be the first.

1. Your phone service will continue to be provided by the existing copper service thus nothing will change as far as your phoines are concerned.

2. You will have no copper line service at all and your telephony will be delivered by digital voice which is an amalgam of VOIP and DECT. I.e voice will be delivered via the fibre to your hub which will act as a cordless phone base station.

Thanks for the reply, Liquorice. Yes, I really hope it is the first option; does that mean that BT will either leave the existing overhead copper cable and run a parallel fibre one (messy??), or does the new fibre cable have a copper strand attached to it/included in it?

The FTTP will be a separate fibre cable

Depends if the Fibre is Connectorised or the old Legacy Blown Fibre.

The Overhead Connectorised Fibre Cable does have a Copper Pair in it but not all Engineers use it and opt to just put up a secondary cable.

If it’s the old Legacy Fibre then you get two Overhead Cables regardless.

Thank you all three of you; seems as if there as many possibilities as people who give them. I think I will simply have to talk to the Openreach electrician on the day and negotiate - but at least I am less in the dark than before. Thank you.
