Full fibre broadband and access gates

[sola_bristol]

We have just been offered full fibre broadband.  We are one of 4 houses in a close accessed by an electrically controlled gate.  Callers to our houses press a button corresponding to one of the houses on a street side panel.  That operates a directly wired telephone line which operates the phone in the relevant house and callers can be let in by pressing a "0" on their handset.  I  see that as part of the full fibre upgrade, the phone is converted to "digital voice" and I'm concerned our directly wired system won't operate with this.  Is that right and would it need to be converted to a GSM system?

I would expect this to be a totally separate system, and not connected to your landline phone service. I assume the gate phone handset is totally different to the one you use to make phone calls?

I don't think its entirely separate.  The street side panel merely has numbers corresponding to the 4 houses (1 to 4).   By pressing those numbers it calls the houses on the standard phone handset and you can talk to the caller and let them in through the gates using your regular handset.  There is no gate phone handset as such, merely the panel which provides an intercom interface with the normal house handset.  If the copper wire to the handset is disconnected then I can't see how our system will work

You will need to speak to the gate entryphone provider and ask how it is implemented and what they intend to do.
