The checker shows the copper exchange.
It only shows the fibre exchange if no copper is present.
Your fibre should come from the same exchange as the fibre from the other properties.
That makes sense. The 100+ FTTP properties most likely don’t have copper present, the checker only shows an FTTP service available. Presumably we’ll retain our copper connection to the local exchange in Muir or Ord, and fibre to the larger exchange in Dingwall.
