Iv'e changed the graphs, to try and just include the 512 tones, but It was either too wide, or as it is now. Hopefully this setting is better, also uploaded again.

Yes, that's better.  :)

However there is something odd with the Bit Loading per Sub-Carrier plot. It is missing the first 63 sub-carriers, those numbered from 0 to 62. I don't know why . . . and I don't know what to suggest.

In addition to the missing tones that have no bit loading. I think its a mystery that wont be solved. I did try another modem today (HG6123B) the plots were the same.

DLM acted at 05:30, put me on 9.1 SNR and consequently speed reduced to 14015

Back to the drawing board ;D

However @kitz suggested DLM was acting on retrains. I guess with the line tests, by ISP, and disconnections but the engineer both here and at the exchange I could have had more than 10.

Well

I received some great advice after my last post, to be pragmatic about this and perhaps settling for the slightly now constant speed was the best course. I couldnít argue with myself as I preach that exact principle in my own role. So it was for a few days stable at the reduced speed.

Then I lost dial tone 😰. When that was fixed at the exchange, my upload sync fell to 444mps with an SNR of 28. Also a further reduction in DS. Iím told that canít be fixed until Wednesday next as the ďorderĒ is ďstuckĒ.

So pragmatism might not always be the best course of action 😠

Nothing I can do, or the kind contributors to this thread can, but I thought an update useful.

Interesting developments. Hopefully you will be able to make a more positive post after Wednesday.  :-\

Well work is still on going, seems to have been escalated to BT wholesale as the DLM is causing some of the problems. However the bit loading on the low tones  has now appeared !

Well. Iím told all the issues have been resolved. At this time the speed and thruput is excellent. The stats look much better than they have although still some missing tones, but perhaps not as many.

I donít know everything thatís been done, but I do know BT wholesale have been involved.

So time will tell.

Things certainly look better after about 1525 hours.

This? "Ecclesiastes 1:9 King James Version (KJV)
9 The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun." :D
