Unfortunately it is truncated.
For me fortunately. :) I've more interested in ADSL2+ band Hlog. VDSL2 Hlog is too inaccurate for this band.

OK, have had an interesting couple of days. Stats are on MDSW user Gedpie, there is a gap that I'll explain.

Looking at Tuesday's stats there is a jump in SNRM to over 7dB, which was unusual. When I got home I discovered my media PC in the garage had powered down about 10 minutes before the SNRM jump, I switched it back on & saw that the PSU fan was seized. You'll then see a gap in the stats, as said PSU decided to expire very loudly tripping all the sockets in the house as it did so.
Now the media PC had an important job at 8PM (recording GBBO) so a PSU was culled from another PC, which resulted in the SNRM going back to 6ish & then plummeting to under 2. Drastic action was needed so the PSU was pulled from the PC doing the MDWS stats, hence the gap in data whilst I sourced a new PSU, which went in yesterday & stats resumed.

So it looks like the dying PSU was causing interference, but I didn't get that increased SNRM when the dead PSU was out of the equation. I think I'll tinker at the weekend unplugging stuff in the house & checking the effects.

My latest stats are below, FEC did go off the scale after the PSU fun, up in the 1,000,000 scale, but things seem to have settled now, ES look almost none existent, attainable is over 38000, still banded at just under 30000 though.

Ah, now I understand the "happenings" that were recorded and viable via MDWS. I'm waiting for a continuous 24 hours set of data but from what is currently present nothing seems to be out of the ordinary.

Looking at the Hlog plot I can see that there is no gross physical abnormality to the metallic pathway, it is just a longish line.

Moving to the QLN plot I can see that the cabinet containing the DSLAM is a significant distance from the serving telephony exchange. The RFI spikes in the DS2 band are probably nothing more than the result of your local topography.

A quick look at the SNRM plot shows that you do not experience a diurnal rise and fall in the margin as a result of long distance radio signals pick-up during the hours of darkness.

Exchange to cabinet is only about 500m, cabinet to house is 1150m (From OR engineers app).

Just after 6PM tonight FEC has jumped up to a steady 1,000,000, what's that all about?

Hi folks, I've donated to MDWS so there's over a week of steady connection & stats to look at. Just wondering if there's any potential for more speed? I live in hope that DLM will remove the banding & G.INP comes to my ECI cabinet.

OK, there's plenty of history on MDWS for my connection now. Had a resync a week ago taking me to 31591 down. Would I be correct that I'm no longer banded? Interleaving is still on though, ES very low on DS & no resyncs, another does show on MDWS but this was just me resetting stats in the router interface, I don't think it actually happened  :fingers:

Is there a likelihood of interleaving going too?

Thanks
