Prior to moving into our new home we got a line report from Chorus showing line attenuation to be 15 - others with similar stats report VDSL speeds of 30mb/s


Now that I'm moved in our first VDSL line (this is for our office line) is showing attenuation of 23 - max speeds for both ADSL2 & VDSL are similar at 18mb/s and that's what we are getting. However I am experiencing frequent glitches.


Would ADSL2 give a more stable line than VDSL at distance? Would I be better asking my ISP to swap me over to ADSL?


Still waiting on VDSL to be setup to the house - and will get a master splitter installed, so will be interesting to see if we get similar/different results compared to the business line.

Yes ADSL2+ reaches much further and more stable over a longer distance when compared to VDSL


Make sure you get a master filter / Splitter installed

Yup, working on getting a master splitter installed. Once I get the 2nd line to the house running I'll see about getting both lines done.


Will be interesting to see the before & after results on the office line

Once G.INP and Vectoring is more universally rolled out, VDSL would be ideal.




In other parts of the world, VDSL is used on really long lines ploying on all the features it adds.


I've seen cases where disconnections can be heavy after VDSL upgrades, Sometimes this is ddDLM settling in.


Take the following example -




After switching, they went through a few days of very frequent disconnections, almost all from our end, able to be categorized as ddDLM related.


This has now dropped down to an average of 1 a day in the early mornings.






Line itself had a history of resyncing once a day, so it's actually settled down to have an improved speed and experience; Be it a painful transition. 






I'll often see cases where chorus will mark a ticket as too far for vdsl, rather than repairing a physical fault.


as such, i personally see 'distance' an over-abused excuse.
