Long term phone contract at home means its not possible to go with a different ISP, much to my disgust, so getting the best out of a bad deal we are getting fibre optic, up to 40mb, supposedly unlimited with no traffic shaping (yet to confirm this). Done some preliminary digging and it seems they send an engineer out who isntalls a bt modem and then connects a talktalk router to it? Is that correct? I will be speaking to them later on to get all the details, is there anything else I should be making sure of? I've seen a bit about LLU on the forums but can't say I understand what that is 
I'm also assuming the hardware they use is probably pants, and I'll be wanting to replace it pretty quick?
