| I'm not sure where this shot came from, but I had a few of those when I was testing the Noisemargin and ADSL Standard of Modemoptions. When Noisemargin was set above Minimum, I noticed similar blackout areas with a 300s delay. I have my setting at Minimum (my system won't tolerate even the next tick above minimum without those delays) and ADSL2+ (this didn't matter much). Note the attachment 1.
Attachment 2 and 3 are my settings from within ST5x6 system setup.
I hope this helps.  |

| Thomson, under pressure from their main European customers (who are ISPs over there), made their FirmWare 'DMT'-hostile so that's what the 300 sec (5 min) delay is all about, exactly.
I think v6.1.0.5 doesn't cause this sort of behaviour in 'DMT'. |

| I have the attached screenshot just taken.
Do we have any info on the modemoptions? Can any of these be modified to further tweak the system for the better? I am not aware of what 00, 01, 02, etc. means. |

| Hi,
I didn't learn much about Thomson's MoDemOptions because this didn't seem to work for me when i still cared to try them but here's what i could get so far:

is it possible, Bicephale, 2007-Nov-2 (Possibly the "Spectral Shaping" and "SRA" bits)
SpeedTouch 516 Tweaking :), Bicephale, 2007-Jun-18 (FirmWares vs experimental tabs)
Here's a post the guy who launched the ST "Buy Groups":

I also read somewhere that the MoDemOptions may still work up to FirmWare v6.1.0.5.0 (ZZQOAA6.105). For more information you'd need to browse the British and Aussie web sites (you'll find the references using my 1st link)...

| Great! Well, i found the information you've requested in a previous post. My advice is that you get the file on disk but never use it if that's possible:
 Home >> Downloads Root / mfcs_G / GNet / BB0060B ADSL Ethernet Router
 Home >> Downloads Root / mfcs_G / GNet / BB2060 ADSL2+ Ethernet Router
You could as well have got want you wanted from GenTek's site by following these links:
http://gentek.com/html/index.asp "Support & Downloads" "Online Public FTP" "ADSL-Modems" "BB2060" "Firmware" "3-C33GTT10-8821" "Download Now"
The MoDem-Help site resquires you to be registered while you need to contact the GenTek guys in order to get a PassWord... |

| reply to TilhasBB Hey guys, I'm wondering what I can do so that I can achieve a 1.7mb profile from Bell (My ISP is Teksavvy). I recently called Teksavvy and a request was put in with Bell and it was denied..I guess they said my connection would be "to unstable" if they set that profile. I call bullsh*t. On my previous ISP (MNSi) I got a steady 170k/s which is like 1.4mbit connection?? But now on Teksavvy I can't? Oh ok!!? Makes sense? NOT! Plus I play alot of games and I realyl can't do ANYTHING with 120k/s (~1mbit) download max... let alone my crappy 160kbits upload thats set right now.
Well after reading this thread I decided to get DMT and fool around. I put on the 6.1.0.5 firmware on my Speedtouch 516 (as I read this allowed all options in DMT). I took a couple screen caps. I played around with the Noisemargin in the 4th tab and when I set it to just above minimum my RCO was around %50, is that good? I'm not to sure what RCO means but I think it means the lower the percent the more I should be able to get out of my line?
Anyways here are some stats:
Modemstate : up Operation Mode : G.992.1 Annex A Channel Mode : interleaved Number of resets : 1 Vendor Local Remote Country : 0f 0f Vendor : TMMB ALCB VendorSpecific : 0000 0000 StandardRevisionNr : 00 01 Downstream Upstream Margin [dB] : 10.5 23.0 Attenuation [dB] : 62.0 31.5 OutputPower [dBm] : 16.0 11.5 Intrinsic/Actual Bandwidth % Upstream : 19 Downstream : 66 Available Bandwidth Cells/s Kbit/s Downstream : 2792 1184 Upstream : 377 160 Transfer statistics Errors Received FEC : 537 Received CRC : 2 Received HEC : 2 Transmitted FEC : 0 Transmitted CRC : 0 Transmitted HEC : 0 Near end failures since reset Loss of frame: 0 failures Loss of signal: 0 failures Loss of power: 0 failures Errored seconds: 1 seconds Near end failures last 15 minutes Loss of frame: 0 seconds Loss of signal: 0 seconds Loss of power: 0 seconds Errored seconds: 1 seconds Near end failures current day Errored seconds: 1 seconds Near end failures previous day Errored seconds: 0 seconds
ADSL configuration: opermode = multi_adsl2plus trace = disabled modemoption = 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00
Not sure what else is relavant..but is it possible to be able to run steady on a 1.7meg profile from my distance to the CO (5-5.1km they say...) and with my line stats?? Help is much appreciated! |

| reply to dcman Hi,
The ST's MoDemOption feature never worked for me until i moved so i'm an apprentice here but this is how i'd put it:
%20.GIF/thumb.jpg) From the ground up!, Bicephale, 2008-Aug-30
FirmWare v6.1.0.5 is fine, i don't know yet if there's any benefit in using another version. What i can see is that bringing the "Noisemargin" cursor down improved my DS RCO figure but this was done at the cost of a lower DS SNR Margin.
Alternately, taking that cursor up i managed to make my connection stable enough for normal use during disruptions (i experience heavy noise on evenings); my DownStream SNR Margin went up as my connection speed went down (this is a trade-off which i don't think can be avoided)...
If you search back through my thread you should find an animated .GIF demonstrating what this tweaking can do; the date was August 26.

| reply to dcman Oh, by the way! Your Error counters are meaningless without a suitable time-frame. Twelve seconds is NOT suitable at all so i must suggest you let the device run for much longer than that (24 h is fine) and then it's OKay to launch 'DMT'! Take note that multiple resets invalidate the time-frame since we don't see when the last reset occured. So, this means if you can't collect long term records where the "Number of resets" equals one then you'll have to settle for a shorter period but it doesn't mean twelve seconds is suitable (unless the phone line gets so bad you can't do better, that is)!...

| I did the setting you suggested for my modemoptions my RCO DS% went up from %66 to %68. My SRM went from 11 to 13.5, and my txpwr went from 16 to 15.5, AFTER I slid the bar up to were you have it. Is this bad or good?
Hopefully my modem stays in sync for atleast 12hrs or so lol, in which i'll take another screen cap. But do you think I would be able to attain a 1.7mbit connection on my line? Like how am I suppose to b*itch to my ISP and have them b*tch to bell that I want it switched for testing purposes when they immediately refuse anyways? FRUSTRATING!!! |

  dcman
@teksavvy.com | Also! If I bring the noise bar down to 2 notches above the word minimum, my RCO is %58...I assume lower is better?? Thanks. |

| Hi,
We get little control using Thomson's MoDemOption and the matter of FirmWare versions remains to be explored but i can attempt to testify based on my own experience and then i'll extrapolate from there.
This capture shows the best RCO numbers i've ever seen for my present line, i believe. It's confirming my assumption that under normal conditions i must be able to get on 6016/800 Kbps FastPath!!! Noise obscures such a prospect, most unfortunately, but it's not impossible that some day i'll get this solved.
Right now, it's obvious there are afternoons during which i might have the best profile available for the money i spend but, until only a few days ago, i just hadn't realized i was able to restore my connectivity on evenings using an ST + 'DMT' tweaks. Relatively to our present case (yours), a DownStream RCO of 50 % or so may sugest that you have room for more speed indeed but it depends on how quiet the line is.
Being this far away doesn't help it at all but i can't tell more without the suitable noise curves anyway.
Back to my illustration, what i know is that i'd have 6016/800 Kbps FastPath during dry afternoons only and i'm not sure Bell would leave it as is, indefinitely, while the "latern" resources would keep warning the phone company that my speeds vary in this fashion.
Maybe there's a similar option for you, maybe not...
I wish ADSL were made sturdy enough to fall-back and "repair" itself automagically but that's not going to happen on the Thomson SpeedTouch 5x6 series if i can judge from what i've seen and read since i bought my ST546v6, about a year and a half ago...
I believe the Siemens SpeedStream 4200 is able to fall-back to 4032 Kbps during a noisy episode but i could notice the connection wasn't as satisfying as i'd like it to be. If this is how ADSL works for a growing number of customers lets welcome ADSL2+!
In the meantime, you should consider installing new FirmWare which 'STMT' supports so that long term "noise" curves become an option... Once you got a better perspective on how the line behaves you'll gain confidence about what the next move must be.
Let me reming you that RCOs in the fifties would be good news only if you have moderate noise, as when living in sub-urban country-sides, perhaps.
Who knows, you may be lucky. |

| the 516 doesn't fully support the adsl2+ spec which is what you want =(
the ability to change profiles as the line gets better or worse doesn't really work yet... give it a few more years before jumping onto one of these units. I have a 3com whic his capable of this an its very rough getting the right firmware which is stable on it. |

@teksavvy.com | reply to TilhasBB So basically their is nothing I can do because my Attenuation of 62 is to high???
Also, with my noise set to the min I have an RCO of 48%. But my attenuation is still 62...does that mean my line is noisy as hell and their is nothing I can do? |

| Hi again,
Sorry but there's no such conclusion in my reply.
The Attenuation level might remain immuable as a rock even if you experiment with RF "chokes" but who can say it's the case until it has been tested?
I do my best so that clues about the "Noise" issue are provided by this thread and the one which it's linking to, i published numerous illustrations there:
»From the ground up!
You'll learn that SNR Margin curves often failed to describe reality, i can even refer you to old threads where the spectral response envelope looks better if the MoDem is located away from one's demarcation box, using a long/cheap non-twisted phone cable!
I've discussed how the use of toroidal ferrite cores as RF chokes may lead to some paradoxal results; i can also show you a curve where one section just looks great while its counterpart is some nightmare come true and yet, in fact, the situation happens to be different. Now, if some curves lie what must we expect of mere static numbers which many of us have seen changing by the minute!? My suggestion is that you collect long term (24 h) "noise" curves, it may very well open your eyes on the big picture.
It's not perfect, there's time & effort involved but that's all i got to offer. Maybe others know better but i'd probably call this gambling on your account!

My advice isn't to give up but to acquire a proper perception of the context. The choice is yours, is it worth my spare-time and yours? The content of your next post will tell me if we can go any further.
