This issue has always bugged me. Am transferring to BT Infinity next week from Sky and have mixed feelings. We live a fair way from the exchange so line attenuation is a problem but we mange to get 3.5-4Mb with absolutely zero outage using the Sky unlimited package. Our current router stats are posted below and I woud be grateful for your interpration of the noise margin figs. Is the 7db download commensurate with a quite and stable connection that bodes well for Infinity? I'm curious cos our phone line is noisy with much background niose despite the fact that we don't have any fancy gadgets and use filters just about everywhere.
I'd just like your views on noise on the line versus noise margin for broadband and how each might impact on Infinity when we're connected next week.
Many thanks for your time.

Note the deliberate mistake. Should be 4Db but it's been 7 for the last few weeks!
Your current line stats don't really matter for Infinity, the only important factor is the distance between your house and the street cabinet.

Many thanks but this speed tester refers to all the ADSL 2 permutations (21Cn etc etc which were all predictably around 4Mb). I'm having Infinity installed so hopefully the only relevant attenuation is that from the cabinet to the house which is about 200 yeard max.
Have I got that right?
Only 100% right as it fibre to the nearest cabinet its distance from that cabinet that matters
