Re: Upstream VDSL?


[re: MHC] [link to this post]
 
Thanks and acknowledging your Telnet figures - which I think are related to the individual Tones/Channels used.

But the OP has apparently posted the basic statistics, not using Telnet.

Is there a chance that the modem is switched to ADSL Mode rather than VDSL; bearing in mind the problems that came to light on -

Yep, we both know they aren�t.

But strange things can and do happen. Has anyone looked to see if any line spurious stats show when this model of router is in use for FTTP.

All this doesn�t help the OP though.

I know his were from the GUI, all I wanted to demonstrate was that some figures are available and probably the overall figure it is just that most modems don't display it, get it wrong, or use 0.0. It should be there in the data and maybe his modem does actually have access to it.

As for ADSL, I wondered that but it still does not stack up and there may still be an issue. ADSL2+ is a 24/1.4 service with upstream at the low frequency end (as you know). So, I would expect to see figures of 20/1.4 in the OPs case. Or if upstream is capped at 400k up the attainable would be at least 24/1.4 rather than the 26/0.48 being seen. The 26 would show that greater than the top limit may be indicated as attainable.

Which modem are you using?
Do you have a modem with a Broadcom xDSL chipset (HG612/Zyxel/Billion/many others) so that you can run DslStats.
This can show us which tones are being used and pinpoint the problem.
It could be that a neighbour has disabled UPBO and is drowning out your line.

Are you able to check the ECI DSLAM firmware version? I've seen version IFTN:0xd086 / v0xd086 cripple the upstream of a couple users a long way from the cabinet.
