Which is essentially the same as saying December ;)

Looks like it may have rolled out here overnight.  Here being Ngararatunua, Whangarei (rural cabinet - KAM/something-I-forgot).

59/10 on DLM-1 (pity the line requires INP and resyncs 24 times/hour without it).

53/10 with manual downstream INP override of 2 vs previous 36/10 sync.

Definitely different use of frequencies compared with an old graph I had floating around.

This is the new @53/10 with 2 downstream INP.




The old  - taken during a power cut 15 months ago.  Ignore the downstream sync rate on there - it was usually around 36Mbps prior to last night.  It's just high in that image due to being the only person on the cabinet during the power outage.  (I wish I had a more representative "before", but oh well.)

cool - so it looks like your upload rate has gone up.  only by about 400kbit but uncapped.  now if you can just make it back onto 17a :)

My line just changed a day ago, My latency went to 8ms and line  attenuation went up form 2 to 4. Will it drop back down after 10 days? After DLM does it thing.

Download is still capped at 70Mbit and upload at 30Mbit, I assume they dont want VDSL to be faster than UFB plans?



Spectrum looks way different now.

It may just be about minimising backhaul congestion.

The latency thing is weird as your line looks wonderful - but there still may be burst noise issues - which often don't seem to be dealt with well at all.  Since council workers have been doing stuff across the road here there's been burst noise issues but it was fine before, and it's put my latency up to 8 msec on down as well, but it still drops out for a minute every now and then (burst noise of like 8000 errors compared to usual of < 10) , and seems to make the line no better at all.  It's cool that it seems to be using the full spectrum now.  Although I do wonder if on connections like yours that lower frequencies (ds0? - the first block) should be just dropped out to allow longer connections to go faster, and your connection could probably still do 70 megabit.

wow, you have an almost perfect line there

i dont know about the 10 day thing, as i assume that the changes dont make it a new connections so DLM will probably be slightly slower.

@seatil - Your original 8b line was so solidly clear im not surprised your 8b on 998 has flyed! the requirement of INP on your line to hold strong Really interests me however... I would peg a bet on it actually makes a serious difference for electric fences or something though.
Obviously rural line, it makes sense that your clean.

Find it interesting to compare your 997 and 998, ill hold off on publicly posting a few conclusions there for-now though. 


@mercutio - Indeed the Upload speed on that line is interesting, Does go about to confirm the statement that has loomed around for awhile... 998 will not on average support any better upload speeds at all over 8b.. seatils line being a rural rare case too!


@cruxis - Thats a near pefect line, i do note your upstream SNR is a little lower than i have seen on most 17a profiles. Be interesting to see if that was a low noise sync or not - Although 30mbit on 17a should be easy.

Your downstream snr, and your spectrum to go with it shows pretty clear signs that it could go faster. There was a comment made by chorus that they were looking at 998 to go 100/30 So, that's probably still in the pipeline and i would expect your line to manage reasonably close to that!

I am curious, are you Whangarei based too?



Your line Attenuation changing is odd, however notable changes in atteuation is about a 2dB jump from adsl2+ to VDSL2 8b and another 2dB to VDSL2 17a (2dB is just an average number, not a serious figure that should be in a book.)

I really wish I had a more representative "before" graph.  The before is only that clean because I was (probably) the only person connected to the cabinet during the power outage. ;-)  Just a couple of days ago it looked much more like the "new" graph in terms of height/bit buckets filled, but with the old bands.

Needing INP is a relatively new development.  For the first 12 months we had DLM-1 with 43-45Mbit, 50Mbit with SNR tweaking.   15-18 months I've seen a steady deterioration, dropping from 43Mbit to 36Mbit and finally needing INP to stay up.  I can only assume that more people in the area are getting ADSL and/or upgrading to VDSL.

Electric fences; hard to say.  Nothing particularly close to our line, but I don't know if fences near other people's lines would have any effect on us or not.  Turning our own fence (200m away from the line) off doesn't make any difference.

I gave up tweaking ages ago and settled for being happy if I could get my day job done on a line that was at least up and running.  :D

I'm picking that's probably because it's measuring at a different frequency again to what it last measured at?  My attenuation has increased another couple of dB.

Honestly, when your pulling off 50mbit on 8b, tweaking is marginal at best and your more likely to just be enduing noise for such limited gains that it isnt worth it.

More advance forms of INP (G.INP for example.) i have seen make huge differences, but your case is the first one i have directly addressed which makes a noticeable improvement.

Yes, that's exactly what the case is. As for your increasing that is interesting to hear indeed. - Although i havent done the math on the spectrum changes between 998 and 997 in respect to the spectrum blocks for that.

My VDSL has changed (Glenview, Hamilton).

2 days ago:
Speed 33/10

Today:
Speed 52/12

Yay..... although I'm getting fiber installed in 12 days so.....meh.
