johny99: Thank you for the responses, I was wanting to know which dB reading is the crucial one. Chorus state they will not install VDSL on a line, with an attenuation above a certain dB, which is 13dB, from what I have been informed . I was not sure if the 13dB referred to the down stream or upstream dB reading. As my upstream is below this, but the downstream is above 13dB. So confused...... just wanted a straight answer.

I would like to know this too. I believe the requirement refers to the downstream however.

If you don't have a master splitter installed and/or your internal wiring has not been updated in 5-10+ years then doing such things will further increase your line quality and improve your VDSL connection in the event you were to get VDSL installed (not to mention it'll help your current ADSL connection too). I have heard of cases where people have had VDSL installed on relatively high attenuations, the only downside is they get speeds around 20-25Mbps, although the upload is usually around 8-9 Mbps which is quite nice.

I'd advise checking out your internal wiring, checking the Chorus coverage map: (http://www.chorus.co.nz/network-upgrade-map), the "20Mbps+" zone is the VDSL zone and calling an ISP to see what they say.

Good luck!
