Lantiq DSL Modem - Line Uptime drift (lagging)

@takimata

I applaud the strive for accuracy, but honest question: What does actually depend on this value being exact, down to the second no less?

Again, the uptime value is generated by the modem firmware, and why it drifts and for which firmware versions and for which modem chipsets and for which line conditions and under which modem load and at which room temperature is anyone's guess. If "multiplying by 1.024062" works for you, great, more power to you.

This problem is specific to the Lantiq modems family as far as I know and from what I can tell I am not the only one complaining and the fix is applied to the lantiq_dsl.sh file not for every dsl modem out there. And like I said the multiplier 1024 should work for everyone don't worry about my number, my curiosity took me far but 1024 should be fine for the masses.

@takimata

it needs to be done in the modem/DSLAM firmware (whichever entity calculates it wrong in the first place.)

I totally agree with you that it should be fixed on the Lantiq modem firmware level. But we don't have the luxury to do that, do we? so we work with what we have, even if it's a patch job to keep things working nice and neat till by a miracle it gets fixed in the Lantiq modem firmware itself.
