Full Fibre as part of the move to your Digital Voice home phone service.

[Keithrg1976]

People  I been back and fourth not getting  very far. 

Bt want to do an install to digital voice 

1 new cable into house to a signal sender that connects wireless to my existing router ? 

This will require a power supply? 

Next up I have a yale hsa3800 system

Will I be able keep this working some how by plugging it into my router ?  

Bt have mentioned supplying battery back ups But only last like 1hr.

Digital Voice requires no change to your existing setup.

It does NOT require a move to full fibre.

If you do not wish to have full fibre, tell BT that you do not wish to have it.

It’s not very clear what it is you are asking , all BT phone customers will need to be DV (digital voice) by Jan 2027 , some customers are also asked if they would take FTTP in areas where it’s available at the same time as changing to DV , but they are two different things …

DV on its own simply needs the phone cord moving from the wall socket to the phone socket on the router , FTTP needs a new ‘line’ provided and a mains powered ONT installing , so as well as the existing router ( this assumes the customer has BT broadband ) needing power so does the ONT .

You would need to check with your alarm provider if it’s compatible with DV , nothing to do with BT
Battery back up keeps the router or ONT and router powered for 1hour , you may not think that is very long , but that’s sufficient time as far as the regulator is concerned , if you wanted to buy yourself a better back up (diesel generator for example ) , nothing stopping you , but BT wouldn’t pay for it , also  BT will only supply what are considered vulnerable customers with a 1 hour  BBU ‘for free’ , if you are not classed as vulnerable and feel you need a battery back up , you can buy one yourself

Is onto the new install that replaces internal wires buy using WiFi to connect to router.
What's fttp is that the upgraded Internet
All bt said was new line to house and box inside. Not very well explained didn't say anything about needing power I was only guessing it will. Not very environmentally or wallet freindly. Why can't the box and router be 1 unit.

Thanks
I was under the impression there would be no dail tone there for phones and alarm won't work. On dv.

It seems you are getting upgraded to FTTP as well as migration DV , watch this video

Not sure about the environment or wallet comment, the ONT is only a few watts, so  costs very little extra in power consumption probably a few pence per month , as far as why not a combination router /ONT , because Openreach are the network provider and BT are the ISP , if you leave BT and go to Sky  (for example ) you still need the Openreach ONT to connect to the Sky router , as you will be sending the BT router back .

You do get dialtone on BTDV ,

your  alarm is between you and the alarm provider, if it doesn’t work with DV they need to provide one that does (if you are renting it ) or you buy a different one if it doesn’t work if you own it outright ….if you want to find out in advance, call the alarm provider, it has nothing to do with BT

Tganks for information

Still another electrical device to run  and keep a back up power supply incase off outage. 

I used contact form to request information 

I really don't want to spend £400 to replace a perfectly good alarm system.  Just to chuck old one in bin.  

Glad I cancelled  install.  

Thanks 

[Keithrg1976]

thanks video helped a bit  doesn't explain why need double socket just ads to the confusion. 

£10-20 a year to run  plus back power for units. 

Can't say I'm impressed

I've also just read the the ont is not wireless so needs cable to run to router.  

Total night mare.

It's not clear why you've crossed out most of posting no 8. Did you mean to withdraw it?
But, yes, for full fibre broadband the ONT has to be connected to the hub/router with an ethernet cable.
This isn't much different from the need to connect the old telephone master socket to the hub/router with a copper cable for copper based broadband.
The ONT only adds pence per month to the electricity consumption, not £10 to £20 per year.

So where am I going wrong here:

If the ONT is 12W

12w/1000w = 0.012kW

0.012 x 24hr x 365days = 105.12kWhr per year

At 30p per unit 0.3 x 105.12 = £31.54 per year
