You've got hope that you're a lot closer than 1 Km!
For a decent FTTC connection you want to be within 500 metres, preferably a lot less. Ideally you want the cabinet positioned just far enough away so you don't have to look at it.
Your existing ADSL sync is irrelevant.
its not 1km ect its 0.2km lol
153metres by crow view 0.2 by road
