G.INP was active hence why you had a speed above estimated range. All your drops/resets when changing router your lost the G.INP and also the speed improvement that gave. Dropping the noise margin won't improve your attainable and you really need to maintain a stable connection at let the DLM reduce you noise margin. And improve speed. This could take a few weeks
your current speed is within your expected range from the dslchecker
I bet to differ. The Draytek gives the option of 'delta adjustment' on the downstream. Available is a delta of -50 to +50, which equates to about +5db to -5db on down stream SNR. The link speed adjusts as expected. Of course if the SNR is pulled down and errors are introduced than I expect the DLS will step in. I would demonstrate this but at the moment I don't want to be screwing around with stuff until the DLM is happy.
I've yet to see anyone on a VDSL connection show any success with this. ADSL yes.
Go for it, I'm happy to be proved wrong.😃
Ewwwww.... at the cost is two line resets...
SNR delta -50
Note far end (down) = 0 db
Banding still in place.
I quickly switched back - notice the attainable on up had not stabilise when I took the screen dump
I'd would appreciate your thought.
Could you expand the explanation for me pls?
RxTxEnabled = 1
In what way? What part of the difference between enabled and active don't you understand?
Please don't think I'm being awkward or anything like that, that is not my intention.
On another note, still waiting for evidence of user modem SNR control being successful/beneficial on a VDSL connection.
No I don't think you awkward. Forums are a difficult medium at times.
Sorry, perhaps I'm being stupid. Do you think ReTxEnabled = 1 means G.INP enabled or something else?
I'm unclear as to your interpretation after shifting the SNR delta. The SNR shows as 0bd with an increase in the attainable figure. The actual bandwidth is held back by the banding. I'm unsure how this shows no effect. Without the banding I think actual link speed would increase...
