Lol. No worries. The sync is down a tad but on a speed test its no worse. Maybe it will sync up at bit at some point. My stats is running 24/7 anyway. Be good if you can have a look in a day or so if you dont mind - thanks! ::) ::)

Under what ID are you uploading to MDWS? I can only see a skytester and no skynewb???

Got that!  ;)  Configured MDWS to display data for your circuit.

One thing I have noticed is that your Hlog plot is not being shown.  :(  I always start with that and consider it in conjunction with the QLN plot.

Are you uploading the Hlog data?

I thought it should be. Will check.

That odd - all the options are ticked but it not displaying it on the mydsl. I have the modem selected as 8800nl but not sure what else it could be?  look like the others are showing but not hlog??

Ok so h612stats has the hlog graph on my pc but its not appearing on mydsl for some reason




Thanks

I have responded to your PM.

It may be due to the 3 hour pause in uploading data today.
I think MDWS only updates Hlog data occasionally, regardless of how often the data is uploaded.

tbailey2 is the right person to ask regarding any issues with MDWS.

Looking at the Hlog plots, that you have provided here, I can see nothing of any concern. Going to MDWS and looking at your QLN plot I suspect, from its rather elevated floor, that you are suffering from a significant degree of cross-talk. The power cut-back in the first DS band can be clearly seen and there is minimal RF ingress. Overall, I would say that your circuit is in good physical condition.  :)

For an analysis of the VDSL2 service that is making use of the physical metallic pathway, I think it is best for me to let others to comment . . .  ;)

hi,

thanks for taking the time to have a look. I have migrated to a new user accounton mydsl being skyECI and Tony has managed to get it working so case anyone has time to have a look its all under  skyECI 

Many thanks

Could you post the 'Plink' log from the time your Hlog was generated locally for me to examine?

a) to look for what might be causing the MDWS Hlog graph problem &
b) to get a 'feel' for your connection.

I might also need to see an extract from your modem_stats.log file (from the Ongoing_Stats folder) at some stage to see how/if any of the currently not graphed data changes.

I could then graph the data locally and/or 'zoom' in to selected parts of it if necessary.

In the meantime, Tony sent me a copy of the Hlog data as uploaded from your connection.

If you look closely at your locally generated graphs, you will see that they creep into positive values at tone 16.

Here's the raw data:-

   0      -96.0
   1      -96.0
   2      -96.0
   3      -96.0
   4      -96.0
   5      -96.0
   6      -96.3
   7      -96.3
   8      -0.8
   9      -0.8
   10      -0.8
   11      -0.8
   12      -0.8
   13      -0.8
   14      -0.8
   15      -0.8
  16      0.4
   17      0.4
   18      0.4
   19      0.4
   20      0.4
   21      0.4
   22      0.4
   23      0.4
   24      -3.3
   25      -3.3

This is a bit of an anomaly as Hlog is a measure of attenuation, therefore values should all be negative.

This happened briefly to Kitz a long time ago (Zyxel modem), so I amended my programs to cope accordingly.
I have asked Tony to check if he might also need to do the same within MDWS.

It appears that wasn't the reason after all as your previously O.K. logs also included positive values.

Tony seems to have fixed the real cause now though.
