scroll down to the bottom - You will see what is available on a one month contract and SMPF on a LONG contract.
Where does it say this? The only reference to a 12 month contract is for FTTP. The original page (from which you made your screengrab) says that FTTC Lite and FTTC Unlimited are on a 1 month contract. In the small print it then says that 'broadband only' is an option.
The price list I linked to shows the options available and does not mention a 12 month contract for any of the FTTC Unlimited packages. To be fair though, it doesn't explicitly say 1 month either so slapped wrist to IDNet.
Still, I'll stop trying to help...
