ADSL Broadband after changeover

[HHGTTG]

I have just been looking up BT's various help pages for setting up DV with latest SH2 see https://www.bt.com/help/landline/digital-voice--how-do-i-set-up-my-service- and this shows the Smart Hub connected to a master socket using a filter and ADSL of course. I thought that when we are told that our switchover is imminent the Broadband to the house would be changed to Fibre Broadband in order for the system to work.

Will ADSL 18Mbps still always be available to operate the new DV system with say you DECT phone plugged into the SH2 directly because the diagram does not show this although I realise the link above is about using a DV phone.

your DV phone will work with adsl just plug phone into socket on back of SH2 not master socket  there is no automatic change to FTTP or FTTC just for DV

Digital Voice is an Internet Phone Service. It does not need the old telephone exchanges instead it uses your broadband service regardless of how that is delivered.

Thanks for that but I don't particularly need to use a DV phone then as I just want to plug my existing Cordless BT DECT phone and base station into the Smart Hub 2. 

I thought the DV phone from BT communicates, for set-up and operation by communicating with the DECT feature built  into the SH2?

[HHGTTG]

So ADSL Broadband will always be available then? The PSTN service will no longer be available at our Master socket. 

Well, i got that completely wrong then and there was me looking at BT Fibre Broadband packages from which I would have to choose.

ADSL won't always be available. At some point in the future it will be FTTC or FTTP.

I assume then that 18Mbps or less will be OK for the operation of the Digital Voice system whether one uses one's own phone or has the DV handsets. In my current set-up I'll lose my hall phone with Speakerphone that is nowhere near any power socket but works from the line voltage from the master socket just below the hall table. My current DECT cordless phone runs of an extension lead in another room where there is power and it's 'satellite' phone in plugged in for power only, elsewhere. Oh well, that's progress for you.

If its like the old Broadband Talk service, then typically 64Kbs are used for a single voice path. If you are using HD voice to another BT DV user, then 128Kbs is possible.

Voice is given priority, but you are unlikely to notice any speed difference.

The copper pair to full fibre rollout and PSTN to DV rollout are not the same thing , the old telephone exchange equipment is being retired, and an all IP ( internet protocol ) taking its place , BT are calling their version Digital Voice , this requires you to plug a phone into the router not the wall socket , and should be completed by December 2025.

It will be many years before everyone has access to ‘full fibre’ , but the bandwidth that DV requires is very small so even ADSL connections ( let alone FTTC  ) is more than capable of powering DV , so for many the copper pair will still be used , but it will be a broadband connection with IP telephony for those that want a phone service , even landline only customers will be on a version of broadband.

The FTTP network is expanding all the time , if someone does have access to FTTP , they can upgrade to it at anytime , at some point in the future it may be compulsory to make the change if it’s available but it’s not compulsory now.

Sorry to go back to this  point again but when Googling about this changeover to DV in general, I keep on seeing that ADSL in December 2025 will also cease to be available, say over my existing Copper wire connection to my house or to anyone else that has ADSL.

This information comes from various sources and links but would seem to suggest that by that date the whole existing Copper network providing telephony will end  which I understand but I am still not quite sure if ADSL will still be available to my house as it does at present.

If that is this case then myself and  many others will be forced to get a Fibre connection instead in order to access the Internet etc.
