Well, I have ordered Infinity from BT and I assured that the engineer will be able to connect to set up the cabinet to get us faster broadband. Apparently, he doesn't need to do anything to the connection from pole to house. I hope I'm proved wrong but I am not raising my hopes.
That is correct, at the moment your broadband and telephony both emanate from the exchange. The engineer will split your line at the cabinet and connect the broadband there instead, your telephony will still come from the exchange. Nothing changes between the cabinet and your house except a different Hub (which will sent in the post) if you don't have a HH5 or later.
was it fitted by en engineer in your home as normally self install? any noise on quiet line test
conenction should not be dropping as you describe
