That's it for today happy with zero ES & SES all day today should be happy for DLM to get back to 20Meg upstream and low retransmission on both downstream and upstream tomorrow I hope so

That all looks good again.
Time to leave it alone and DLM will doubtless give you the full 20Mbps back before too long.

because there is no connection uptime on it and will not work with dslstats and hg612 modem stats.

So why are you even thinking out shelling out a few hundred pounds for a Fritz!box which wont either ...  nor will the wifi be any better than your TPlink  :-\

The reason I queried what you said about the Fritz!box is because you would most likely be wasting your money for what you need/want.

Updated: No DLM action yet but remain stable with zero ES / SES but still on High Retransmission on both downstream and upstream. @Kitz - ok I stay with both Billion with TP Link for now until Full Fibre come along (FTTP)

I would be delighted to get G.inp back on my upstream. I remember many moons ago I had it for a while and gave me nearly full upstream speed. Now I'm sitting about 14mbps.

I can't see how the DLM activation of US G.Inp can be responsible for the climbing SES count.

I would be more inclined to accept that recent work in the cabinet has disturbed the tie-pairs for your circuit and it is now malfunctioning in a non-linear sense. Whatever the malfunction, it is probably manifesting itself at the low-frequency end of the band. 

If I remember right he reported his DS attainable also shot up, suggesting that work perhaps rearranged a lot of pairs, so these errors could be a improperly connected pair or perhaps some nasty crosstalk affect on the US.  I am inclined to agree with you its related to this work.

Still no action on DLM yet. I do believe now that upstream are banded at 19Meg for a long while now because the downstream stay at 80Meg with DLM will take no action.

DLM take action this morning just after 6am

The change are:

Downstream   Upstream
Line attenuation (dB):     11.9   (before was 11.8)   0.0
Signal attenuation (dB):   Not available on VDSL2   
Max (kbps):                       91788      32553
Connection speed (kbps):   79999      19000 (no change)
SNR margin (dB):           8.6      12.5
Power (dBm):               12.5      0.6
Interleave depth:          16      4 (before was 2)

G.INP:                     Enabled      Enabled
Vectoring status:          5 (VECT_UNCONFIGURED)      

Interleave depth   16                 4 (before was 2)             
   INP                46.00              49.00 (before was 56.00)           
   INPRein            0.00 (before was 1.00)               0.00 (before was 1.00)           
   Delay              0                  0     

Look like upstream are banded at 19000Kbps instead of 19999Kbps.  :(

DLM continues to do what it's supposed to. It was implemented and tuned by professionals, not people contemplating how best to irritate a random customer in Telford.

It responded to a severe error condition fairly promptly, it will monitor and only adjust the parameters back once the algorithm is confident it's safe to do so. The worst possible response would be to put you back into conditions where you've packet loss.

Is the loss of 999 kbps of upstream capacity really impacting you so profoundly that you feel it necessary to watch every parameter change as DLM adjusts? Far more impacting was the packet loss that DLM resolved for you.

Still throughput speed of 70Meg out of BTw Bras IP Profile 77.35Mbps. I guess PN profile are incorrect one (again) but for upload I lose 1Mbps from it. Normally I get 74/19

Do the people who thought that there must have been something physically wrong with adslmax's line think that it's now been fixed?

The reason I queried what you said about the Fritz!box is because you would most likely be wasting your money for what you need/want.

Probably getting it free when moving to Zen?

Finally at last DLM has restored everything back to normal now  as upstream are now back at 20000Kbps ;D :)
