I speaks to your total lack of understanding on this matter , that you think that if a ‘phone line’ was provided before ‘broadband’ was invented that it cannot possibly be used for broadband…it’s a pretty simple concept to grasp, traditional telephony is on its way out , VoIP will be the way telephony is delivered in the very near future, those that have no need of ‘internet access’ but do require ‘landline’ type telephony will ( even if they don’t realise it ) be provided with a basic broadband connection for DV.
They will have no choice but to be migrated onto it ( if they want to keep a BT supplied ‘landline’ phone service) they will be given the date of the change , and an extra bit if kit supplied , that plugs into the mains , and told to take their phone out of the traditional phone socket and plug it into the newly supplied ‘box’ which is really a cut down broadband router ,and , hey presto, they are on DV.
The ‘limited’ broadband product they have been supplied with is one that is of no use for ‘internet’ access because of its limited bandwidth , but this limited bandwidth product will be more than capable of supporting VoIP telephony.
The overwhelming majority of existing copper pair lines ( from the 1970’s or even earlier) are more than capable of delivering this service , there is no need to wait until 2025 to establish that, there is no practical difference between a copper pair installed the 1970’s ( or the decades before that ) to a copper pair provided today…if someone doesn’t have this limited broadband now , they will be provided with it to enable them to use DV telephony, BT may even ‘help’ with the installation of the ‘router’ for some ‘vulnerable’ groups of people, but for most it will be self installed, it’s hardly rocket science after all.
The only issue with DV ( and VoIP in general ) is unlike the plain old telephony system that’s being retired, is that it needs a power source at the consumer end ( for the broadband router) whereas the current phone system doesn’t, so local power outages stopping the phone service working can be a concern for some ,but your claim that there are ‘ incompatible lines’ is simply wrong, obviously there are lines without a current broadband service …they will be provided with a limited broadband service as and when they are put into DV ( but everyone will be on it before the end of 2025)
As already said , if someone has been told that their line cannot have ‘broadband’ , that was on the assumption that the broadband service would be needed for internet access, the reduced bandwidth broadband needed for DV will work on those lines , because it’s only VoIP that it will be used for .
Telephony only customers will be the last group to be moved onto DV , so probably don’t need to concern themselves with this for a couple of years anyway
