It wouldn't be cost-effective for Openreach not to provide the PSTN connection at the exchange so as to achieve naked DSL, because the user could change their mind at will, (minimum terms aside). So that connection could repeatedly need making and breaking, perhaps simply because the user changes CP.
Just wondering as well, something I nearly posted before you raised the issue of it needing a full review of pricing, given a physical connection between the premises and exchange, how legal would it currently be wrt the USO and dial-up internet, and I expect there is something about the 999 service in there as well.
