OpenWrt (Chaos Calmer r46559) for ECI/r v1 & v2 - Update: G.INP/ReTX Support
j0hn:
Looking further the line attenuation (latn) reported by both modems is very similar at 10.1dB and 10.2dB.
The attainable rates (attndr) are dramatically different. They have dropped from 91/24 to 74/15.
The attainable rate is usually exaggerated when Interleaving is enabled but as Interleaving is enabled in both instances it shows the scale of the drop.
Such a drop in the lines potential can be from a physical fault but it can simply be due to crosstalk (interference from new subscribers lines that run alongside your line in the main cable bundles).
Such large drops in attainable due to crosstalk are all too common unfortunately.
Hopefully the engineer finds a physical fault on the line somewhere and fixes the cause of the disconnections. With a DLM reset on top the sync rates should improve considerably.

Fingers crossed, will update tomorrow morning after I speak to the engineer.
Any information you suggest I have ready for the engineer? Anything I should to do to prepare to make things as easy as possible for them to find the problem?
jaimbo:
So the engineer came around yesterday and potentially identified some internal issues with the wiring of the master socket and extension which he resolved and then done a bunch of tests with his tester which apparently all passed.
Then double checked that my modem could still get sync, I pointed out that there were still errors on the upstream which he said he "wasn't worried about" and he was only worried about errors on the downstream? After that he done a DLM reset which has left me with this:
Very happy with these speeds. Fingers crossed I don't see more instability and get hit by DLM!
j0hn:
Just an FYI. The upstream ES/SES in your stats are old errors reported by the DSLAM.
They don't reset when the modem is restarted line the downstream does.
It looks like an excellent result. Stability is key now so keep the modem in sync and enjoy the connection.

The line issues started happening about 3 weeks after that screenshot. Part of the reason I bought the HH5A was in case the ECI modem was dying as I really couldn't figure out what was causing my issues. An hour or two into an outtage I decided to test with a few different devices/firmwares and I couldn't get DSL connected at all on either my build of OpenWrt 19.07, jsamuels 15.05 build or even the stock NowTV hub until eventually it started to connect a few hours later. Some mornings the line would drop after 10-15 minutes and wouldn't be back up for like 30-45 mins. It would continue doing this for like 4-5 hours at times, really annoying.
Well at least now with the HH5A I can have fancy graphs for historic stats! :)

If you still around? Do you mind posting how you got those graphs working and in which build of OpenWRT, I have worked on the same thing and ended up giving up due to LUA errors.
