OK - I need to find a way to improve my upload speeds. New requirements mean I have to sync a massive amount data on a daily basis to a remote backup, and on some days this will be larger than the amount I can transfer overnight (3-4GB or more).

I'm currently on an ADSL2+ connection with Vodafone (Naked BB FS/FS). According to ISP "what can you get"-o-meters my address is ADSL2+ only.

I believe I'm connected to the Memorial Ave exchange in CHCH, however if I look at the Chorus maps, I'm 2 houses away from the ">20mbps" VDSL area served by what I believe is MMA/Q on Withell's Rd.

Enable haven't even included my street in the next year's plan, despite being 300m down the road. They have to connect Avonhead School, and unfortunately instead of continuing their progression southwest to include my street, they're going to overbuild Vodafone HFC all through Sockburn/Middleton, then build a tiny little extension northeast to connect the school.

So, my questions:

 

 

1. Am I getting the most from my line? (see OrbMT output below - apologies for ze German). Feed from street is the old two wire thick copper stuff, I've installed a master filter that got me from ~4.5 down to just under ~12. Have dedicated ADSL Jack, isolated old wiring, and have Cat 5e everywhere past the filter.
2. Do any providers in NZ support ADSL2+ Annex M for improved upload speeds? It doesn't appear that Vodafone do, at least - my modems just sync ADSL1 if I try to force Annex M on 2 or 2+.
3. I'm only a couple of houses down from where VDSL is "technically" available - however as you can see below my line stats indicate a much longer SNR, and it appears that the street cabling goes toward the MMA exchange and not toward the MMA/Q cabinet. Is it possible to even get onto this cabinet? Or is this a hard wired topology thing that will never change?
4. Would getting a second line installed get me on the other cabinet? Or is this a completely pointless exercise?
5. Are there any other options, short of driving to a friend with unlimited fibre each night and begging? I've toyed with the idea of 3G/4G, but at $50/day for the amount of data I need it's.... absurd.

 

OrbMT output for reference. Middle boxes from L-R are Max Line Rates, RCO, SNR, Attenuation. Downstream on top.

My line attenuation is 26dB, but I have seen it at 21dB once or twice. It's also 21dB if I use ADSL2 (non+) or ADSL1 modes with my modem.
