Upgraded ADSL 10Mb to 20Mb about a week ago and got this on the WAN:

Today I am syncing at what must be ADSL2+ maximum download potential.
Changes noticed, Downstream SNR has dropped from 15dB to 8dB and Interleaved Depth has increased from 32 to 64.

Connection seems fine, uneasy about the lower Downstream SNR and higher Interleave Depth.
 
Damn Guy, are you living right next to the Exchange? Very good Line Attenuation, SNR on the other hand also seems fine but not great, you should be fine as long as it stays above 6dB, anything below that and your line will be unstable and will disconnect frequently.

Upgrading to the VDSL profile should improve the stats, but that also depends on the router used. Tip, get a more expensive VDSL router and not the cheap ones, trust me it's worth it.

Watching the SAIX Noticeboard for DSL migrations.
We may even have VDSL2 already, but according to 10210 Technical today my profile on their screen only gives ADSL2 or Multimode and no VDSL2 Option. I called them because of the new higher DSL Log readings on the WAN of my router today, thought something might have happened on Telkoms side due to the new higher 24959kbps (20479kbps) downstream sync.

I have the Asus DSL-AC52U Router which is VDSL2 compatible and yes I live next to the Exchange that has no VDSL or FTTH options. :whistle:

[MENTION=6284]BTTB[/MENTION], so you on VDSL yet? My exchange was upgraded a week ago and I am still waiting for the Coverage Map to be updated.

My exchange was upgraded almost 2 months ago, yet can only get 10Mbps according to the Telkom coverage map... F&*k Telkom!

Cancelling my line as soon as Vumatel is done with my area. :whistle:
 
No VDSL here yet, despite living next to the exchange.
I checked the Openserve ISP Coverage portal and you can zoom in right to your DP board. Our DP board next to our property says 20480kbps, which might well be the most up to date checker there is for your location. Then I checked the surrounding area for their DP Boards and it varies but what I found odd was that there is an area about 4kms from us which I am pretty sure gets fed from our exchange where it shows all 40000kbps and must then be VDSL.
There have been upgrades at our exchange according to the SAIX Noticeboard but I think for the moment ADSL2+ max is our speed.

I am currently 22719kbps and it does download faster than the 10Mb I was on but for some downloads its much of a muchness and you are getting 10Mb anyway.

I feel like a chop when it comes to Telkom. The Netgear ADSL2+ Router I bought ages ago for the then new ADSL2 technology that was coming then has long since died from old age and here I am still waiting for Telkom to step out of the dark ages of internet technology. I would not be surprised that my new shiny ADSL2+/VDSL2 Asus DSL-AC52U upgrade might also pass on before Telkom eventually upgrades our exchange and the pole (DP Board) gets the 40Mb speed upgrade.

I am not a big downloader, but would like a stable internet experience when I want to use the internet and while its OK for the most part I think the VDSL boost will improve the experience and of course the upload speed will be better.

These are my stats. Am I correct in assuming that I should be able to upgrade to 20Mb? No one at Telkom thinks so.

If so, I am sure that I should be able to go to 40Mb VDSL as I am sure my exchange was upgraded.

Your attainable rate is only 23MB so unlikley you can do 40MB, but yes you should be able to happily upgrade to 20MB.

And then you will probably have to fight them to switch you to VDSL so you can get the 5MB upload speed.

Once on VDSL check stats again but unlikely you'll get 40MB.

So the same applies to [MENTION=6284]BTTB[/MENTION] in the first post? Will he also not be able to get 40Mbps VDSL?

I don't see why you won't be able to, my attenuation is higher than yours and my SNR is lower but I'm sycing at 45Mbps down and 10Mbps up.
 
Voodoo, your attainable rate will increase the moment your profile is changed to VDSL2 (PTM), if available of course?
The maximum attainable rate for ADSL2+ is approximately 24Mb.

I realise that I have posted this to you in a PM but perhaps its a statement that should be put out there for debate.
"If your DP Sync Info on the Openserve Portal shows a DP Speed of 20480kbps or less available at your DP Board, the technology is ADSL2+ or less, meaning ADSL2+, ADSL2, G.DMT, T1.413 or G.lite. The last 2 technologies of which I am not sure were even available in South Africa as I understand it was only ADSL1, 2 and 2+.
However if your DP Sync Info on the Openserve Portal shows a DP Speed of 40960kbps it can only be VDSL2 technology. The overlap comes with the 20Mb accounts available though Sales at Telkom as both ADSL2+ and VDSL2 can achieve speeds of 20480kbps. Unfortunately it seems that Telkom Sales are offering 20480kbps at a lot of non-VDSL2 DP Boards and the confusion is that those profiles can be upgraded to VDSL2. Only DP Boards that are capable of 40906kbps speeds can offer VDSL2 profiles to existing 20Mb accounts. Checking the SAIX Noticeboard for DSL Migrations can alert you to upcoming DSL upgrades, unfortunately upgrades are not only Exchange dependent, the DP Boards need to be compatible too if you are looking for the VDSL2 profile change."

Unless you are someone that needs to download continuously, an uncapped account as example, then a 20Mb ADSL2+ can be beneficial, otherwise remember that ADSL2+ is fickle when it comes to Noise (SNR) and attenuation, so sometimes higher isn't better and a 10Mb ADSL2+ account or less is perhaps better when you live further away from the exchange. Noting having read from other member experiences that VDSL2 is great but also has distance from the exchange limitations but by all accounts is better than ADSL2+, notably with the upload side of things and line noise (SNR).

Hope this helps, please add your comment if you would like to add or disagree with what I have stated. Thanks.

You can only really know for sure once actually switching to the VDSL modulation.

Based on the current stats it says no.


That being said when switching from 20MB DSL to 20MB VDSL I only saw about a 2MB increase in attainable rate and not a magical jump up to 40MB...so chances are probably not 40MB but maybe 30MB...which I wouldn't do if I'm paying for 40.
 
I also recently saw a big dip in my line's noise margin, but it's been detrimental because the service has worsened. Interleave depth is probably also now very long. I'd move to VDSL if it turns out the exchange can do it, because hopefully the different profile handles my line better.
 
Woohoo, got upgraded today to 20Mb VDSL. Here are my stats: (Compare to my 4Mb ADSL stats a few posts up)
