Sure. Here you go... The modem is a Draytek Vigor 130, in bridge mode.

For those that have been moved to baseband 998, can you post your suburb as well so we can get a feel of the speed of the roll out.

My VDSL2 is on 55/10 now, am interest to know what speed will I get once I'm on 998.

Thanks!

was more looking for things like attenuation etc

Looking at that snr, ild suspect the hard cap is 70/30 for vdsl now.

Will be interesting to see a modem that displays it with it.


as seen in your snr and your graph, your line is doing exactly what it should, maxing out and pulling back a tad.



Actually.. here we are.

Aside from backhaul capacity and wanting to move people to UFB, is there any reason why they wouldn't just take the brakes off on these profiles and allow the line to go as fast as it can?
Would this result in more interference/crosstalk or any other issues?

ild expect if the line was allowed to go full noise, there would be a fair bit of crosstalk, compared to currently.

Realistically, if your after that speed Fibre should be the key anyway.

That line in particular, IIRC has an attainable of 100mbit (which i honestly, wouldnt be surprised if it hit that high given the specturm)

to be fair, its a near perfect line however.

Thanks for the info chaps.

Apologies. I did try hunting around in the menus to get more info, but couldn't find anything. I'll try again, once I can wrestle my lad's laptop off him again (the only one with a rj45 to plug into the modem!)

So does that 'empty' space get allocated as download or upload?

upload, but from what i've seen the lower frequencies tend to have worse signal.  the best seems to be slightly past where adsl2+ ends...  so because a lot of users are still using adsl2+ and not yet on vdsl, as more users start to go on vdsl there'll be a better spread .. but as it stands, it's tones above 512 that tend to fare better....

there's a whole 8 mhz of bandwidth extra available if they enable 30a.  but i don't think that's likely to happen. (short lines could use 30a, medium 17a, long 8b, extra long adsl/hsns)

US0 on 998 and ADSL are exactly the same size.

Logically i see the move as for edge cases, allowing the downstream to go further while offering "adsl" upload still, Likely a slight step up with a few attenuated bits in US1.


Ild like to see 12b be used for Medium lines, 30a would be a good usecase for pushing really short lines noise right down though.

i think 12b and 17a are pretty similar.  i'm mostly thinking of making use of spectrum bandwidth more so there's less noise on adsl frequencies.  really, it seems that it'd make the most sense for most people to be on vdsl.  so if for some reason someone is 2km from exchange they'll get less crosstalk...

but then vdsl2 is meant to work even on long lines, ... i wonder what it'd be like at 2km etc.

12b ild put as a middle ground between the 8b and 17a, where the line is capable of making use of that extra US band (which is what 12b adds onto 8b) squeeze a bit more upload out, and potentially distribute the noise a tad.


2km, honestly ild say that is about what chorus will start offering out to, where you would be getting like 25/1.5 At best.. Likely Less.
