So I can do 100Mb potentially over this?
... Sign me up! I will try to map out the topology of the phone wiring. There is also a utility room/cupboard thing outside which I don't yet have a key to. I know it has the gas cylinder and power and water meters but I'm guessing the electrical services come in via there as well. I'd like to make sure that the phone line isn't connected to the exchange still before I start connecting things to it.
Thanks for your assistance.
