I switched from Orcon wholesale to Telecom VDSL Ultra last month (location Beach Haven, about 2km from the exchange and 400m from the cabinet). The changeover was 3 weeks ago. I already had a master splitter and have been running my ADSL on a dedicated cat 5 line for years so internal wiring isn't a problem.
ADSL speeds have been 13-14 MBit down and 1 up since we changed to wholesale after cabinetisation, although there have been slow spots of about 6-7 (remember when that was fantastically fast?).
Initial VDSL speeds were 13.7 down and 9.7 up with a latency of around 35, which was ok. I've left it a few weeks but it has never wavered (points for consistency at least). At least the latency has dropped down to 5ms which is great.
I logged into the modem and found the following stats:
Bearers generic info DS US
Payload rate [Kbps]: 37522 10351
Attenuation [dB]: 12.4 26.4
Margins [dB]: 12.3 18.4
Output power [dBm]: 13.5 -0.4
Number of bearers: 1
Bearer 0 DS US
INP [DMT symbols]: 0.00 0.00
Delay [ms]: 0.00 0.00
Depth : 1 0.00
R: 0 0
From my reading on the subject this is now on the optimum DLM profile and I would have expected download speeds of about twice what I'm receiving, if not more. Is my understanding correct on this and if so, just how long does it take? Should I be hassling tech support about this yet?
