How to fix Interleaving on VDSL?

[ghostRgg]

So somebody I know finally got through to do an upgrade from ADSL to VDSL and its been quite the process. After they spent ages trying to get their normal ADSL to fast path, but once the upgrade went through it seems like Interleaving is back on.

This is so chaotic for ping times and when gaming is a priority it just messes it all up. Is there any solid way for them to keep it set to fast path?

I remember I struggled a lot to get Telkom to permanently convert me to fast path when they randomly put me on interleaving, the extra speed was cool but nowhere near worth the ping increase (from 15 to 60).

Unfortunately the way that VDSL works in SA is that you have to have interleaving, it's just built into the technology, and it's the only way you are able to achieve VDSL speeds stably.

So there's really nothing you can do about it since fast path isn't even an option on VDSL.

Go back to adsl, that's what i did.

no one at a ISP knows what "fast path" is. Ask them to remove the ASSIA profile from the line. your isp will sent this to openserve and they will know exactly what to do. when i was with MWEB they have a system that can control your line in its entirety, without contacting Telkom. they can do this within seconds.

Is @TelkomZA still around?

"Charles" will know how to do it.

I wonder if interleaving on VDSL is the reason I can't watch Twitch streams at 1080p because I'm limited to 6000kbps per stream.

I can watch 4 or more 720p Twitch streams simultaneously with no issue.

Makes me suspect that interleaved VDSL establishes multiple connections in order to attain the full speed.

Fine if you're downloading non-realtime stuff, but no good realtime stuff like HD livestreams.

Both fast path and interleaved are "built into the technology" (it's part of the standard) and no, interleaved is not required to achieve VDSL speeds stably. Most of the time if you're moved to VDSL you should already have a good enough line that going interleaved would make no sense, the default for VDSL should be off, Telkom doesn't do it though as they'd rather not have that 0.5% (pulling a number out of a hat, it's pretty low though) increase in call-outs, but they're also doing it because they're no longer maintaining the copper and this is the way to make it last the longest before retiring it (though technically they could just use an automated test to check packet loss on the line and then enable if detected, which ASSIA can do https://www.assia-inc.com/wp-content/uploads/2015/04/DSL_Expresse_Retransmission.pdf)

Would disabling interleaving drop the upload speed on a (for example 20Mb) VDSL down from 5Mb to 2Mb? That's the one thing that was holding me back from pursuing getting it disabled in favour of "Fast Path".

No, it should not, but that's a profile setting from Telkom. I doubt they would have set it to decrease your upload though.

The thing is, technically the default upload speed for 20Mb VDSL package is only 2Mb. I believe it's only because of Interleaving that it achieves 5Mb. Same with the 40Mb VDSL Line, I think the default upload is 4 or 5Mb, but with interleaving you get ip to 10Mb upload.

I mean I know it's not built into the VDSL technology itself, but with the way Telkom/Openserve designed their network you can't disable interleaving on VDSL.

You can however still get them to disable it on ADSL, which I was able to do 2 years ago but it's not an option on Telkom VDSL.

I think it is possible to enable fast path on 20Mbps but it would become 20Mbps ADSL and not VDSL, so your upload speed would go to 2Mbps.

40Mbps is VDSL only, so it wouldn't be possible on that.

Actually I started out on 20Mb ADSL the day my upgrade was activated. Had to request a switch to VDSL.

The absolute max upload is only 1Mb on 20Mb ADSL. The much needed upload speed boost was the only incentive for me to switch from 4Mb ADSL.

Yeah, it's so much nicer now that I have fibre so I can have good up and down speeds and have better latency than DSL, instead of sacrificing one or the other.

You're gonna laugh at me because I already have Fibre in my area. Even had the CPE installed and tried it out, but I've had to hold off adopting it as my primary connection.

I need a truly dynamic IP address, and apparently that's not an option on Vumatel. I know it sounds odd, but there's a good reason why I not only prefer, but need to have a dynamic IP.

I'm on Openserve fibre and it works basically the same as DSL, every time I reboot my ONT I get a new IP. But I've heard that Vumatel is pretty much static.

That's your ISP messing up or you're using the wrong DNS server.

Ebay thinks I'm in a different country?

When I view a listing (even my own listings), the shipping section gives me shipping info for South Africa. Example: This item does not ship to South Africa. Thing is, I live in New York in the good ol' USA. What on earth did I do? I checked my addresses on file and they all say New York...

I wish there was a specific way to contact somebody like that. Most of the contacts via other means of support don't even understand what the issue is. Let alone that all that is needed is for interleaving to be disabled.

Yeah honestly, that's why it was such a mission. I DM'd them on Twitter and Frank responded after like 2 days, then it took another 2 days for them to switch me to fast path.

Then after a week I got switched back to interleaving again, so I DM'd them again and Frank responded again. I asked him if it was possible to permanently switch me to fast path and with some convincing they did it a few days later.

It definitely wasn't an easy task to get them to do but if I had tried to phone them I would have never got someone who even knows any of the stuff I was talking about.
