Evidently you already had G.INP on the upstream without checking the box for upstream PhyR, so it seems doubtful checking that box is going to get G.INP back into use on the upstream. It could have been a coincidence that the DLM decided to enable it for mlmclaren.

Just a reminder that I (at least) am absolutely sure that the PhyR settings on the modem have absolutely nothing whatsoever to do with G.INP.

I experimented a month ago, and unticked the "Downstream PhyR" box the GUI of my 8800NL. Changing the setting caused a resync ... but the link came back up with downstream G.INP running, and it hasn't subsequently gone away.

Maybe the PhyR option on the 8800NL applies to ADSL only... Like the SNR tweaking.

SNR tweaking depends on how the DSLAM is configured. I expect it would work on VDSL2 if the DSLAM configuration permitted.

PhyR is a bit different. It's a Broadcom specific technology, and would only work with a DSLAM designed with that specific technology. G.Inp is similar but not the same, and I doubt very much if the PhyR controls in the modem would have any effect on G.Inp capability.

Resurrecting an old thread
For the last couple of days the upstream error seconds went through the roof - from under 10 per hour to around 200 per hour - presumably due to the high pressure forming.
Then this morning at about 9.00am the system reacted and G.INP is now on the upstream with the speed increasing from about 8,500 to 9,998 kbps and with no error seconds reported

Excellent news. Thank you for sharing.

Now I don't understand how DLM works on upstream
G.INP removed and set to minimum interleaving with speed reduced
Code: [Select]
Downstream Upstream
Line attenuation (dB):  21.2 0.0
Signal attenuation (dB): Not monitored
Connection speed (kbps): 41777 8374
SNR margin (dB):        6.6 5.0
Power (dBm):            12.6 4.6
Interleave depth:        8 1
INP:                    47.00 0
G.INP:                  Enabled Not enabled
Vectoring status:        5 (VECT_UNCONFIGURED)

RSCorr/RS (%):          0.0173 0.0054
RSUnCorr/RS (%):        0.0000 0.0000
ES/hour:                0.36 26.1
