The other thing about dual or quad paired BB/DSL is that the copper pairs have to be balanced as well (two or four identical pairs) - especially for the longer distances from the equipment. Ok for Urban/commercial environments - not very often found in rural ones (because it doesn't normally mater for single circuit use)


Cost wise you will be at least doubling your line rental per month from Chorus (Via your RSP)




Never known the above mattered, that would make a further complication with any multiples i suspect.




Always found Proper bonded dsl to be fairly higher than doubling the line rental, to the point it wasnt worth it at all.

On your attenuation alone you'd not be able to get VDSL. While Chorus has made changes to the attenuation limit to allow more people to get VDSL, it was only raised from 10dB to 15dB. With a reading of 30+dB on your connection, that would indicate you still won't be able to have it. If that reading shows up on the prequalification we are not even allowed to raise an order for it.


In regards to your last paragraph - combining two ADSL streams - I have not heard of this ever being done, but somebody else on here might be able to advise on that with more authority than me.





Hey, interesting that you say that about the dB - I was also under the impression that they have hard limits about maximums etc ... have had a few discussions with VDSL techies being on the edge of the VDSL coverage area with other buildings etc but see what you think about this ... I am a little confused myself..




I live in Kaiteriteri about 3km from cabinet - until Dec 2015 we were so dark age we could only get ADSL1.  Then finally upgraded to normal (minus fibre).  Connected with ADSL1 and sync speeds were roughly 5000/500.  Upgraded ADSL2+ 7000/680.  Gave up on dsl in Dec last year as load on networks were too high assume due to the crowds of people coming here for holidays - bring on the 4G RBI - brilliant! (but alot more expensive and only 80GB)


Last week rang to add a VOIP phone to RBI - salesperson now informs me that VDSL was all of a sudden available .... I was very surprised to say the least!  I knew the attenuation rates of the ADSL2 and how far we were but I thought - lets see what he is talking about.  Sure enough literally 36 hours later I had VDSL installed - new modem etc.


See below - have they opened up a can of VDSL on remote locations that I have not heard of?
