As I was getting good error stats on my long wire from the exchange, I asked to get interleaving switched off on my line – i.e. fastpath. So with nothing else apart from standard ADSL2+ and fastpath I get:
And I get the following summary from my Netgear DG834PN
ADSL Link | Downstream | Upstream |
Connection Speed | 6100 kbps | 1157 kbps |
Line Attenuation | 48.0 db | 24.7 db |
Noise Margin | 6.1 db | 6.4 db |
Assuming things stay stable (based on the advanced stats) I will go for a lower noise margin profile.
