Re: ST516v6 SNR Margin Tweaking 101


[re: JinxterX2] [link to this post]
 
Hi,

Great program working well on my connection with a ST585.

Only gained about half a meg on my sync speed, profile is stuck at 2meg on the BRAS though...at least for now anyway.

When I "save settings" is this stored in the router or do I need to run the program whenever the router is rebooted?


TIA

Not unless you reset to factory defaults.

What was your attenuation before the 536? SNR margin of 2.5db isn't good, I'd be suprised if you didn't lose sync before 11pm.

SNR was about 56 on the 7633 but more importantly the snr was about 3 and hardly fluctuated. I'll check the logs in the morning and report back but I'm quietly confident that everything will be OK.

Everything fine overnight, snr still steady at 2.5 dB. I've had just over 2000 CRC errors, about a 1000 HEC errors and about 1600 errored seconds in 12 hours. The connection seems stable purely from a usage point of view, I've just downloaded 100 Mb of a Linux ISO and IE is reporting a transfer rate of 417 KB/sec (my IP rate will still be 3.5 Mbps until Monday night)

All in all looks OK

Nice one My SNR margin stability has improved since moving the router as far away from the pc and monitor as possible modemoption00=60 is giving me rock solid syncs between 5600-5800Kbps and 14.5-16db margin during the day with 8.5-12db at night, but still with thousands of CRC and HEC errors, however they don't appear to affect anything so I'm not too worried about them, being on a non Interleaved, noisy line. Average download speed (non Peak time) is 550K/sec.

Any idea what the options "power cut back" and "trellis coding modulation" mean? I've got them both ticked at the moment.
