Yarwell has kindly given you a link to my list. You will also find the owner page of that one is a description of how FTTC works, as your existing copper connection to your existing cabinet is still used.
The result is your attenuation is over the distance to your cabinet (plus a few metres), not to the exchange.
The only problem you have is that Infinity is cheaper than all the alternatives. This is apparently to do with how BT Broadband connects to the system at their end.
The good things about the other ISPs is that:
- most will accept orders a bit below the 15Mbps estimate level that BT Infinity cannot be ordered below, though if the connection speed at install time is below the 15Mbps limit the installation is aborted on any supplier;
- they often make it available as soon as your cabinet is enabled, whereas Infinity may be later due to marketing plans or sheer BT inertia, (though the time difference may only be a couple of weeks);
- most are preferable to BT in many people's eyes;
- possibly shorter contracts than BT.
