FTTC - Will Speed Affected by A Nosiy Phone Line?

We're just about to switch from ADSL to FTTC fibre. Because we're right at the very end of the country, speeds are currently very low (around 1Mbps and the guaranteed fibre speed will only be 2.5Mbps) but OK for our needs.

After some pretty bad weather, our phone line has developed a bit of noise (nothing too bad but you can still hear hissing etc on the BT Silence test) and I was wondering if it will have any effect on the throughput of our soon-to-be-activated/installed FTTC fibre (which, of course, still uses Copper from the cabinet to our watch station). Of course, there would be no impact if it was going to be an FTTP connection but, for some reason, BT doesn't want to lay fibre from the cove, up the cliff, to our watch station

Thanks

Depends on what frequencies this noise exists on.

Only real answer is that you won't know until you try. Generally a bad noisy line will often impact on DSL.
