Re: SpeedTouch 516 Tweaking :)
'DMT v7.35' will do, you can try 'STMT' or 'OrbMT' as well. |

Loss of sync | 
Lots of Rec.Errors |
Would anyone be so kind to suggest something to get a more stable connection? I already asked the Bell tech (through the Sympatico direct forum) to switch me from Fastpath to Interleave, and I assume this will be done tomorrow. Should I also ask for 4032/800? BTW, the help I'm getting from the direct forum is very good, I just wish I didn't have to spend so much time getting back to where I was a week ago.
My line is split where it enters the house, with Cat3 directly to the modem, and the other half double-filtered, with a single phone on it.
TIA - ardo. |

| The problem i have with the SpeedTouch is that i catched
mine resetting its counters silently between two samples:
the CRC counter came close to zero instead of going up...
Of all the 3rd-party utilities, in the case of an ST5x6 v6,
i'd favour 'STMT' against 'DMT' or 'OrbMT' because this one
might allow you to collect a few 24 h CRC "noise" curves.
But, if you must trust "static" numbers gathered by any of
these TelNet-based tools, it's possible that some pattern
might emerge from enough of this data but i wouldn't bet
my reputation on such patterns knowing what i know!!! All
i can infer from the above captures is that you're about 4.2
Kilo-meters away from your DSLAM, "electrically" speaking.
Since you asked to be put on some Interleaved profile, at
4.2 KM from your peer DSLAM/C.O./whatever, i'd say 4032/
800 Kbps Interleaved should be OKay and maybe even 5056/
640 Interleaved, etc. In any case, it's your "noise" history
i'd like to hear most about because, in the end, if there has
been very few irrecoverable errors then why bother at all?! |

| First, thank you for you kind help & suggestions. Second, when my modem goes down & brings torrent connections down with it, it does bother me. Also because I've tasted how good, painless, and transparent it can be with the 2Wire. That, and the fact that my actual bandwidth is about 1800 - that's down from 4300 with the 2Wire. I could be extremely happy if I didn't have to think about the noise, gather statistics, etc. I will try those other programs you've mentioned, but I am leaning towards just buying another 2Wire for $25 and shoving the $50 ST516 into its box. |

| Oh, sorry, i guess i missed your point about the resets!
Well, i have four DSL MoDems here and two of those are
brand new. Of all the long term records i've collected, this
is the best and it was using an old GNet BB0060B device:
»Re: Tweaks
I'm afraid i just can't testify that i've ever been able to
observe an equivalent result (fifty days without any reset)
with my Speedtouch 546 v6 on-line; at best it can last a
few days, probably never beyond a week but i must admit
i still have to fully evaluate the late FirmWare (there's been
a dozen since i purchased my ST546). Other guys are very
satisfied with their STs, i'm not that convinced but maybe
this newer FirmWare would be better, go figure. What i can
write is that the SpeedTouch does (or perhaps did) reset a
lot so if you can't afford frequent disconnections then i do
believe it when you claim the 2Wire worked better for you.
Unfortunately, that's the thing with DSL... I wouldn't have
spent this much money on MoDems if i felt like they were
all the same and that more wasn't better. I read that you
already implemented Centralized Filtering, next on my list
there was Shielding then RF Control via ferrite chokes... I
hope you won't have to go that far with DSL but even if it
is preferable to use twisted lines over flat ones i'd still try
to keep any phone line section as short as possible. Use
EtherNet cabling over long distances if you must, a MoDem
will be happier when located closer to the demarcation box. |

I seem to be having some issues with my Speedtouch 516v6's connection stability.. it's not so much that the modem disconnects (or rather, it never does) but sometimes the bandwidth will just choke and lag for a couple seconds at a time here and there, also general upstream performance seems fairly unstable (will upload 90kb/s one minute, then a minute later 50kb/s).
Looking at DMT I seem to be getting alot of errors, my ISP (Telus) uses ADSL2+ which I have forced into ADSL1 mode to get proper pings (in ADSL2+ mode I get 35ms to my first hop, ADSL1 mode I get 8ms). Telus does not offer fast-path mode so it's required to run ADSL1 mode to get around it. I don't get these errors in ADSL2+ mode, upload/download speed decreases by about 200kbit in ADSL2+ mode as well.
Is there anything I can do to reduce the frequency of the errors while keeping in ADSL1 mode? The modem is hooked up to the outlet with a fairly short telephone cable that came with it, and is run separate from all other wires.
I'm currently running the 6.1.0.5 firmware, because DMT doesn't allow me to manually set ADSL1 mode on newer firmware versions.
Here's a screenshot of DMT: »unf.ca/elanzer/img/dmt/dmt20080704_1922.png |

| Hi Anonworth,
What you wrote about performance reminded me of
the days when i considered that the stand-alone
routers were for "power-users"... You have to
know that my usual bandwidth consumption rarely
reaches beyond 20 Giga-Bytes and that's why all
of my DSL units function in "MoDem/Router" mode.
Perhaps if you notice speed variations it would
be a good idea to configure your SpeedTouch for
"Bridge" mode and to run a MiniWAN adapter (if
your OS is Windows) with some SoftWare FireWall
instead. That way, you'd be able to compare how
the SpeedTouch 516v6 behaves in your own case.
Actually, i'm not even 100 % sure you've got to
put an ST5x6 into "Dumb MoDem" mode to be able
to use the MicroSoft MiniWAN adapter at all: i
always thought that the MoDem would change modes
automatically... I'm not sure you can't force
the ADSL mode neither but it's quite possible
'DMT' doesn't support this option with the late
Thomson FirmWares (those people declared war to
'DMT', after all). In my optinion, the syntax
simply changed slightly and you'll only have to
connect via 'HyperTerminal' in order to access
its interactive simili-GUI (text-mode) VT menu!
If you type "HyperTrm" at the Windows command-
line and nothing happens then 'Hyper-Terminal'
isn't installed but that doesn't mean you can't
TelNet to the SpeeTouch's TelNet CLI, actually:
telnet://speedtouch.lan
(start 'HyperTerminal' from a browser)
telnet speedtouch.lan
(use the W32 console-mode client!)
See what happens by clicking on this link then
try Thomson's TelNet CLI with FW v7.4.3.2 ready!
Even better, lets use 'user.ini'! Euh... And
while i'm at it... Ah yes, here it is... The
syntax for the late FirmWare should look like:
So, when you try the very handy "menu" command,
watch for what the internal Wizard suggests for
the mode field by pressing [Enter] as if you're
about to make changes and then take note of all
the available modes using the browse key (it's
an arrow key perhaps, i don't recall exactly)...
Once you know the full TelNet CLI command to use
with FirmWare v7.4.3.2 it should be possible to
incorporate it to 'DMT' through one of its tabs.
Of course, i'd be much more optimistic if you
had a chance to play with Spectral Shaping but
it's not a feature supported by the SpeedTouch.
Some time ago i was told that ferrite chokes may
just happen to implement so raw form of Spectral
Shaping, if you must have such control then i'd
start to play around with toroid chokes, maybe!
What i can testify about is that i had little
hope for the SpeedTouch until i tried its newer
v7.4.3.2 FirmWare. This would force you to give
up on many 'DMT' options but i think it's worth
a try. What else is there to loose anyway?...

| Hi everyone,
It does look like the 'ANSI T1.413' standard
could relate to a form of Sprectral Shaping;
this 'DMT' capture was for a SpeedTouch 5x6:

This other capture is for a SpeedStream 4200:

| Hi fellow tweakers!
Now here's something a bit intriguing to me: i've noticed
that the SpeedTouch 5x6 works either on eighteen volts
A.C. or either on twenty-two volts D.C. - and i actually
have two transformers of each design specified as such:
the linear one is A.C. while the new "green" one is D.C.,
exactly as you'd would expect from this pair of stamps:
%20.JPG/thumb.jpg)
Click to see a larger picture!
So, here's my question... Which is best? Linear A.C. and no
self-generated high-frequency content or Switching-Mode
D.C. with high-frequency content, God knows where in the
DSL frequency spectrum? I can't install identical FirmWares
on both to make comparisons since i don't have the means
to re-install the "DV"/"GE" FirmWare variations which i got.
So, any speculative bets? |

Hello Mods and members!
I've been lurking and working on tweaking my SpeedTouch 516v6 using the information posted on this site.
First, thanks for your hard work and effort in helping noobs like me, and making this stuff simpler.
I started out with downstream around 500  (I didn't know that you could tweak this modem  ). Now as you'll see from the stats, I'm up around 3776 downstream. Old dog, new trick. 
I am using the UK version (it shows 546 in the screenshots). It would appear that I am far from the CO (~7km!). I'm with Primus.ca and I have posted speed and quality tests on the DSL site. The speed test below was from Speakeasy using Java.
I have slowly improved due to the following changes:
1. downgrade firmware to 6.1.4.6 (7.4 did not cut it);
2. eliminate tangled telco and power lines;
3. use a 3" CAT5 cable between modem and Trendnet router
4. unplug vintage (1965) rotary dial telephone borrowed from my university dormitory
5. tweak settings like RWIN and MTU using DRTCP
I am not sure whether there is anything further that I can do with the tools at hand. I would appreciate any further assistance that the forum can give.
Here are my stats. I've attached a final screen shot of DMT. Thanks for these tools as well.
