Hopefully @Starwire2000 will drop in on this as he installs FTTP

Re: FTTP - wired phone bell ring?

FVA delivered via FTTP has a normal sounding dial tone that you get with a Copper Line with 52v DC.

The bell rings as normal on your phone.

To be honest I’ve no idea how ONT makes the phone ring. I know a Copper line sends 75v AC down the line to the Capacitor that trips the phone to ring so I assume the ONT does something similar. Just a guess though as I’ve never asked how it does it or been told how.

Ref to Extension Bells, couldn’t say if they’d work or not as I’ve not come across one yet.

I know Community Care Alarms work with it though.

Re: FTTP - wired phone bell ring?

There would be a ringer converter which generated the required 75V AC. This type of device was in common use on Private Circuits, where it was used to convert 2280Hz signalling tone, to 75V AC to the remote phone or PABX (Private Automatic Branch Exchange).

Its quite a simple electronic device and can easily be accomodated within the ONT.

Re: FTTP - wired phone bell ring?

Got a faulty one in the van, the old 2+4 one but principally the same.

I’ll open it up and have a look inside.
