That's fine. As I thought, (the checker was to give confirmation), you are on what is called a WLR (Wholesale Line Rental) line from Openreach and it can be transferred to any ISP at any time if you wish, with no fuss about disconnections. The ISP quoting all the stuff in your first post was confused by the TalkTalk. Your line is not on the TalkTalk network
No mention of FTTC in that report, but at least you now know it is cabinet 3 when FTTC gets to your exchange. Not all cabinets on an exchange are enabled at the same time, and some possibly not at all. That checker is the one to keep an eye on, as well as the exchange itself.
