STMT - RCV, 24 hours CRC-Errors Curve feature |
Really, with those RCO, Attenuation and SNR Margin
figures, euh... Oh, and the flatness in the shape
of your envelope, euh... You should have no issue
and yet the UpStream bandwidth speed appears to be
too high or the wiring is causing quite an obscure
problem. I regret that the "UpTime" of your 'DMT'
sample makes it almost useless in terms of errors,
i'll use it but this may lead to innaccuraties!...
We can estimate your "Transmitted CRC" error level
to be of 2562/day or so. This is catastrophic for
someone who has an Interleaved profile, i believe;
it's the worst part because i don't know what kind
of failure will cause such an UpStream BottleNeck!
Usually, it's the upper bandwidth that's affected.
Perhaps it's a strong local A.M. radio station, in
that case you can try centralized filtering before
anything else in order to limit the antenna effect
of your wiring. Then, i'd strongly suggest to put
a Toroïdal Ferrite choke on the power supply lead,
near the MoDem. 3rd but not least, shielding with
ferro-magnetic materials does help but it would be
an option only to one who resides in his own home.
Please, try to get a reasonable CRC Error curve by
using 'STMT' in order to obtain one that's similar
to what you'd get from a SpeedStream 4200 D240 and
'DMT v9.01'. A few static numbers hardly suffice.
Try them all if FirmWare v7.4.1.7.0 won't work but
i recommend starting with the v5 ones 1st since it
provides additional features when used with 'DMT'.
It's an opportunity to remind our readers that the
author of 'STMT', BoxFan, added the 24 h CRC Error
feature on my request. This was meant to help the
SpeedTouch owners by allowing them to obtain a CRC
Error record from their Thomson device and yet not
even one single post has ever shown such a capture
since the release of 'STMT v0.7.2' six months ago!
Common people, the least you can do is to use this
tool. It's still a young project and there may be
bugs but, if you're able to collect real "dynamic"
statistics under the form of CRC Error curves, i'm
suggesting it's about time to give BoxFan FeedBack
that he has owned by working continuously for you!
Just follow the links or is it too much to click!?
