My cab has a power connection (not sure if its switched on though) however our exchange isn't yet enabled.
I'm confident that when the exchange goes live it will be one of the early cabs due to proximity to the exchange and fibre having to pass it to get to the rest of town.
I've also checked that sky fibre is available at nearby exchanges so we should be ok for the GEA link.
