So you want to know when you can get FTTC, you know the exchange is enabled but you need to know if the GreenBox (normally at the end of your street) is enabled and if not when?
You can check using this link, http://www.dslchecker.bt.com/pls/adsl/ADSLChecker.AddressOutput
UPDATE: 16/02/2017: The Link is working again! 🙂
UPDATE 17/10/2016: It appears the above link is now dead. If you know of another then please let me know….. if it’s not back by the end of the month, I will remove this page. 🙁
