recently i asked my isp [Acanac] to switch me from interleave to fast path, as i was having far higher pings than i wanted (over 50ms for just about everything). on interleave, i used to have 5056/800 down up and now i am stuck on 3008/800 after having been put on fast path.

i asked the guys at acanac for my line stats after this happened and they told me that my line was doing this:

SNR 14 down, 14 up
Attenuation: 53 down and 35 up

and told me that i could not get any more out of my line. my modem, a versatek versa 170pr, was reporting:

SNR: 30.5 down, 11 up
Attenuation: 10 down 4 up.

given this, i wanted to double check with another modem, came across this speedtouch and got DMT. here is what the modem gives me:



with this in mind, is my ISP lying to me/giving me false information? are the stats from my modem trustworthy? am i maxing out my line? do the stats even look normal? from what i can tell, my stats are basically too good to be true...

I've verified the stats on my friend's line and his line gives a far more normal curve, where the blue area is not practically flat, and his modem says he is pretty much using RCO ~70% for up and down.

in any case, if anybody can shed any light on my situation, it would be greatly apreciated. Going from 5 mbit to 3mbit is a loss of 66% speed. worst of all, pings have not dropped more than 5 ms.

thanks to all who input their opinion]]> http://www.dslreports.com/forum/remark,21438836 Mon, 17 Nov 2008 00:53:19 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,21322908 Bicephale : Hi Chopp,

There's no reason to upgrade if you observed
no difficulties. Your router problem appears to
be quite common around here, the last related
post i've seen was this one as i recall, actually:

»Access Modem on WAN

I don't use a separate stand-alone router myself
so you'll get better advice from router owners...

'DMT' can be run under 'WinE' sometimes, the one
application which runs even more successfully if
using 'WinE' (e.g. Linux/OSX) is 'RouterStats' or its
trimmed-down version 'RouterStats-Lite'. There's
no spectral response graphic in 'RS' but i yet got
to see it fails in a 'WinE'/Linux environment.



Addendum:

Euh... And 'RS'/'RS-L' is said to generate diagnostic
logs too which may allow one to create noise curves
but still no spectral response graphics, though...]]> http://www.dslreports.com/forum/remark,21322908 Sat, 25 Oct 2008 01:57:13 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,21321714 chopp : I haven't experienced resets & disconnections as far as I can tell anyway.

What firmware would you recommend I upgrade too? I did have the modemoptions enabled, but was not sure what to change anyway.

Also what changes can I make in my x-wrt router, to be able to connect the one and only M$ box to the modem with DMT, without having to connect it directly to the modem?

Thanks

Are you experiencing resets & disconnections?

You can try to upgrade the FirmWare so that
the MoDem will only negociate for an ADSL v1
connection. The DownStream rate would still
be comparable (6016 Kbps) while the UpStream
rate should become 800 Kbps, which i suppose
will take care of the bottleneck you've got...

Does 6016/800 Kbps sound acceptable to you?

The DownStream SNR Margin will most probably
take a hit but yet remain within suitable limits.

The UpStream SNR Margin will certainly raise
by a couple dB at 800 Kbps; this would bring
more stability but i'm not even sure you really
need it!

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!

:p

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.

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.

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)!...

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:


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)...

animated .GIF demonstrating what this tweaking can do;
the date was August 26.

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.

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'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 :p (I didn't know that you could tweak this modem :uhh:). Now as you'll see from the stats, I'm up around 3776 downstream. Old dog, new trick. :D

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.

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:

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.

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:


ST5x6 (v6.2.17.5-AA) Experimental Tweak

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?...

;)

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.

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.]]> http://www.dslreports.com/forum/remark,20683592 Sun, 22 Jun 2008 23:53:07 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,20682930 ardo : 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.]]> http://www.dslreports.com/forum/remark,20682930 Sun, 22 Jun 2008 21:21:41 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,20682851 Bicephale : 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?!]]> http://www.dslreports.com/forum/remark,20682851 Sun, 22 Jun 2008 21:01:37 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,20682266 ardo : I bought ST516V6 to replace my 2Wire that got fried in a T-storm last weekend. Still running the original firmware in bridge mode, with my WRT54GL doing the rest. Even though the profile is 5056/800, my actual bandwidth is more like 1800/640. IMO, the 2Wire was handling my noisy line much better than the 516 is, and did so out-of-the-box with no tweaking. Even when the 516 re-connects, I sometimes don't get an internet connection, and the router shows the same IP for my address and the gateway. I find this really weird.

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.

Somehow I get very high latency from 516v6 f/w 6.2
between a computer and the modem
when doing traceroute

1 hop
=======================================================
Tracing route to 192.168.1.254 over a maximum of 30 hops

BTW, the second hop is on fast path ADSL2
and if i use udp traceroute from the modem CLI it's ~20-30 ms

===========================================================

192.168.1.2 is Windows XP computer (disabling Windows firewall doesn't help)

At the same time when doing speedtest.primus.ca
shows 20 ms latency!
(and I have on average 50 ms just between PC and the modem)

Any ideas?

It's quite possible 'DMT v9.01' doesn't provide MoDemOptions
for the SpeedStream 5200, it's built for many brands/models,
after all. I witnessed a similar phenomenon using 'DMT v2.20'
and two different GNets: the BB0060B "Trellis Coding" item
is accurately reported by its capture while with a GBB2060-Xi
it's not (and yet i can flip this option via the TelNet CLI).

It seems the 'DMT' TelNet CLI scriptor is fault tolerant as it
needs to accomodate different pieces of HardWare/FirmWare
from various manufacturers so it makes sense not to abort if
only a part of the script is broken... The one difficulty i've
noticed with 'DMT' is that sometimes the device's replies
may slip through before it could catch them and hence one
gets the impression that 'DMT' is dead. I found out that i
simply needed to click on [Refresh] to make another try at
reading those TelNet CLI replies.

The fact that you don't have a full Attenuation record is
probably due to the differences mentioned above. At this
point, it would be a good idea to call your ISP and to ask
them to get you a Line Test record from Bell's portal. It
will give us a better perspective as to what this MoDem
is good for. Later, you should do the same with your other
units since it would allow you to compare them, actually...

Once you know which brand/model provides the best RCOs it's
going to be easier to decide on what to focus your efforts.

Even if your SS5200 isn't the best solution you'll still
have the means to monitor long term noise on your phone
line. If there's a line problem that certain techniques
can cure then the SS5200+DMT noise curves will confirm it.]]> http://www.dslreports.com/forum/remark,20504612 Mon, 19 May 2008 01:38:14 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,20504521 Bicephale : Hi,

a TelNet CLI scriptor. Use the UserName/PassWord
you'd use for a TelNet CLI session. In case of more
trouble though, i think the magic word is "FTP 5200"...

In other words, don't use the UserName/PassWord which
the ISP associated to your PPPoE sessions but which the
MoDem's manufacturer associated to your DSL device.

The SpeedStream 5200 might be a special breed of MoDem/
Router but i'm confident you'll find other SS5200 'DMT'
captures around that might boost your determination...

As you can see at the setup, there is a different device for the adsl and a different device for the telephones.

Now, the ISDN splitter either consists of a high-pass filter (adsl output) and a low-pass filter (phone output) or just a low-pass filter (phone output) with the signal at the adsl output unfiltered, without having any problems at all (the router handles the situation as it should).

When I have my NT1 device connected into the loop, I get instantly a decrease of about 5db in my upstream SNRM, which means there is "noise" coming from that NT1 in frequencies that it shouldn't (in the adsl upstream range) and the low pass filter is not able to cut them off.

That's why I need to change my NT1 device, or get a better filter.

PS. My adsl annex b devices are a USR 9107 and a speedtouch 536i.

catastrophic for the DSL one, don't you think? If you
filter-out the DSL signal, the MoDem just won't sync...

Usually, the filter isn't installed ahead of the DSL unit:
it filters non-voice frequencies, ahead of ordinary phone
equipment. A filter meant to be installed in front of
your ISDN-compatible MoDem that filters out the ISDN part
without affecting the DSL part would be unselective and/or
introduce excessive distortion using analog components.

This situation calls for digital techniques and that's
exactly how the DSL MoDem works, hence my suggestion that
you simply need to find a more selective DSL device.

I am using one (with analog components) at the moment, like everyone else with an adsl over isdn line, in order for the NT1 device (and with it the telephone) to work. All I need is one of better quality. Is it possible? I'll find out when I try it. :)

It's true that ISDN and DSL bands are close, although after looking once again at the illustration you posted above, I saw a difference that I hadn't spotted in the first place, which is the range of the ISDN signal.

Here in Greece we have 2B1Q ISDN and not 4B3T, which means the ISDN signal goes up to 80kHz and not 120kHz as the illustration shows.]]> http://www.dslreports.com/forum/remark,20468154 Mon, 12 May 2008 02:11:14 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,20466930 Bicephale : I'm afraid a low-pass filter isn't the fix you had
in mind unless your house wiring is acting like an
A.M. radio antenna. The ISDN and DSL bands are so
close i doubt a filter made of analog components is
even possible, actually. The MoDem is responsible
for ISDN rejection: because of ISDN you lose all bins
below 37, i believe, and digital filtering does the
rest. If ISDN signals are a problem then the most
practical solution would be to try another device...

Godd luck in your quest towards a better service!

The graphic at the bottom of the .PDF document
shows that this is a low-pass filter capable of
rejecting most of the ISDN band and also beyond,

very lucky, some manufacturer may have a band-
pass filter on his shelves that rejects ISDN only...

Based on TerTech's own post in the other thread
i considered that the curve on our side of the
Atlantic may happen to be slighty lower and this
is why i devaluated your maximum attainable speed
should you live around here. There has to be room
for variance, in any case, so i guess that you'd
still be justified to hope for 10 Mbps. Perhaps
i got something to help you filter the ISDN band:
it's from a European guy, probably a neighbour...

Do you think 60 dB rejection @ 40 KHz would be OK?

If so, see the filter circuit shown in this post:

Up to a point that is, since imo we can't blame crosstalk for everything (after all, a network should be optimized and should follow the standards, thus the rate hit by crosstalk should be under control and in the acceptable range).

But in my case, crosstalk is not an issue. Taking the NT1 out of the loop, gets my upstream high up to where it should have been in the first place.

Looking at the graph above, I guess my speed would be close to what I have here, if I lived in your area.

Now for that router and its settings that got 1,7Mbps with 78db attenuation, since we currently have no extra info, all I can say is that this is not a common thing to see.

As for DesiGuy1981, I agree with you, that he could get around 2Mbps, if all things worked at maximum efficiency.

We're seeing more and more degradation cases where the
customer complains that his UpStream speed is lower than
it used to be. In my opinion, Cross-Talk would explain
this situation easily if we could accept that DSL has
gained popularity through time - which means Cross-Talk
levels must have increased a great deal during the last few
years. In my region, the phone company is using strudy
flat copper pairs to bring our DSL signal from the pole
to the house, that's where some progress can be made: i
showned it by turning a noisy & slightly unstable 4032/800
Kbps FastPath access into a quiet & stable 6016/512 Kbps
InterLeaved one using shielding and some RFI control...

The previous ADSL graph is for the 1st generation DSL
service, i believe ADSL2+ would have twice as many bins,
e.g. 512 bins instead of 256. By the way, did you try
to force your MoDem to negociate ADSL v1 only? That's
not going to solve your problem definitively but the
additional stability that it might bring would be one
more clue to guide you in the right direction... Sorry,
i don't see how to help you other than to mention that
TerTech is using a SpeedTouch with FirmWare v6.1.0.5.0
('ZZQOAA6.105') in combination with 'DMT' MoDemOptions.
The same person also shown me where his DSL device is
located on the graph by John Bullas (from Flickr site)
and i'm afraid that your speed might be even worst if
you were living around here, according to the curves;
DesiGuy1981, on the other hand, can expect up to 2M5
bps unless TerTech's unit is marginal. I wish i knew
what MoDem John Bullas tested to read 1M7 bps @ 78 dB
but i don't suppose he kept a record of that...

Tone 32 (138kHz) to 64 (276kHz) for upstream and 64 to 512 (2200kHz) for downstream.

You are also correct about the fact that a trade-off (especially in the upstream rate) is not preferable and that one solution is expensive filtering circuits.

I've searched the internet extensively for a high quality filter that could cut the "noise" that my NT1 is injecting into my line in frequencies that it shouldn't, but unfortunately, although I tried a couple of splitters, I couldn't get one that does the job. My next move will be to try to construct one myself, when I find the time.

Changing that crappy device for a newer model would possibly make things better too, but that's not an option atm, so for now I've decided to live with it.

For your question now, because I am fairly new with the forum and I haven't been used to following lots of threads easily, could you provide me with some details regarding the graph?

From what I get, you are looking for a router's chipset that could provide a DS rate of around 2Mbps, for a 78db attenuated line? Where does that graph data come from?]]> http://www.dslreports.com/forum/remark,20465027 Sun, 11 May 2008 11:30:45 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,20464995 dslgr : If DesiGuy1981's modem readings are correct (which we can't take for granted), then my guess is that the Remote Tx Power is lower than it should, due to misconfigured power profile at the CO DSLAM (you also use the word exchange for it if I'm not mistaken?) or bad ISP network topology.

There's a reason PSD (Power Spectrum Density) masks are being applied and that is mainly to reduce crosstalk among lines in the same bundle.

If all things worked as they should then, by ADSL-standard definition, the Maximum Nominal Aggregate Transmit Power for the Downstream is, as you correctly said, 20dbm and for the Upstream 13dbm.

That means that in a properly configured providers network, for DesiGuy1981's case, there should be room for a signal power increase, leading to an increased downstream rate. But unfortunately, as it seems, since the call has already been made, that's not the case here. :uhh:]]> http://www.dslreports.com/forum/remark,20464995 Sun, 11 May 2008 11:23:10 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,20459388 Bicephale : I don't want to minimize your problems, i just think
that the ADSL2+ protocol probably serves you right
under these circumstances.  You mentioned being on
ADSL2+ Annex B, here's the illustration i could get:



You may have to use relatively expensive filtering
circuits to reject the ISDN band as it is closer to
the DSL band.  Perhaps you should ask your provider
to do the tweaking for you:  for example, request a
change to 9984 Kbps/512 Kbps if they don't mind...

Euh...  But i read that you want to win on all bets
so that won't work for you i'm afraid!  So, if no
trade-off is possible on the software side then you
are left with your phone wiring.  Anything you can
improve?  Still in the HardWare department, i have
this riddle for you.  The answer might point at a
solution which many of us might also benefit from:

I don't know about dslgr but i was as professional
as any other user when i subscribed to DSL for the
1st time so i'd like to help you save the time and
frustration if i can.  You don't have to embrace a
learning curve as steep as mine was, just consider
that the existing 3rd-party trouble-shooting tools
will help you to acquire a proper understanding of
the situation.  'DMT' is the most popular, use the
version corresponding to your MoDem, if supported.

My favourite trouble-shooting tool is the 24 h CRC
Error ("noise") curves generated by a GNet BB0060B
using 'DMT v2.20';  those from an Efficient SS4200
with generic FirmWare combined to 'DMT v9.01' seem
even better but i haven't tried that one just yet.

:p

Typical SNR Margins are approximative as they vary
throughout the day, sometimes they're even totally
paradoxal.  See for yourself by reading this post:

SpeedTouch 516 Tweaking :), Bicephale, 2007-Dec-11

According to the record shown above, it's possible
to register normal SNR Margins during a disruption
and then to read mediocre values once the noise is
gone!  Of course, some people here will argue that
my GNet was faulty but my reply to them is that it
must be a self-healing GNet then!  The same people
will brag around about the SpeedTouch which didn't
provide any "noise" curve at all until i asked the
author of 'STMT' to include this function;  try it
if you have no alternative but be warned that i've
catched my ST resetting its counters unexpectedly.

Anyway, i suggest you keep in mind that trade-offs
are required while tweaking and that you shouldn't
rely on SNR Margins (static numbers) only:  try to
gather stable feedback from a mix of RCO figures &
long term CRC Error rate curves as you toy around.

;)

Now, here's what i mean by 3Com:  "3Com USR-910x".

That's a MoDem brand/model and the D-Link DSL2320B
has an equivalent Spectral Shaping capability.  My
underlying thought, i must confess, is that i'd be
more optimistic if you could use other HardWare!!!

Only three units are known to do Spectral Shaping,
only one of them got its tweaking abilities tested
(GNet's BB0060B) and this item was discontinued so
you probably won't find one of those in your local
electronics store.  As i wrote before, practically
no interest could ever be raised relatively to the
Spectral Shaping topic and all we got to gather an
overall picture of this feature is my own numbers.

In other words, you may end being your own guru...

:uhh:

Congratulations, the average unsatisfied DSL users
would rather switch to cable than enter this quest
alone!  Phone companies like to lower profiles, it
isn't profitable to send skilled technicians every
time a customer complains and 3rd-party ISPs don't
give orders to them:  at best they open "tickets".

:huh:

Normally, only you can pinpoint wiring problems or
evaluate devices in search for the ideal candidate
and there's no garantee you'll succeed in the end.

Phone companies like Bell would go bankrupt should
they compete with cable via pre-emptive techniques
such as systematic twisted-pair wiring, shielding,
RFI control by using ferrite toroids if necessary,
and, why not, on-site DSL unit tweaking (if it can
support it - which it doesn't, usually)!  I may be
mistaking but it looks like Bell and others chosen
distributed filtering over existing phone cabling,
in hope that the subscribers would be satisfied to
finance the next fight (with help from ADSL2+ when
the time has come).  I bet our forum didn't become
so popular because the phone guys guessed right...

Their plan left a few customers behind, welcome to
your new DSL neighbourhood!  After a while it will
feel like amateur radio:  the hobby makes us busy.

:o

Well, i don't want to end my message on a negative
note so i added captures to boost your motivation:





Now, imagine if we knew the answer to this riddle:

After all, that's what got me into this tweaking expendition I started some time ago. If everything worked as it should, then I probably wouldn't look any further.

First of all my line is up to 24Mbps/1Mbps, which for me that I live about 2,5-3km away from the CO, means that I get to enjoy about half of that. My line is ADSL2+ over ISDN (annex b), rate adaptive with a target SNRM of 9db for the downstream.

It usually synchronizes around 10-11Mbps DS and 650-700kbps US. I should have been able to have 1Mbps upstream but that's where my second problem arises. The upstream takes a big hit, mostly from my NT1 device (the device where the phones connect in a ISDN line). That's why I was looking for a spectral shaping solution, but unfortunately haven't been able to find one till now.

Wish I could do some tests for DesiGuy1981, but as you have already said, our lines are disproportionate. :uhh:]]> http://www.dslreports.com/forum/remark,20454099 Thu, 08 May 2008 21:53:53 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,20453699 Bicephale : Hi,

Perhaps there's next to nothing to tweak on your side
simply because nothing is really broken as some of us
around here would consider 24 Mbps with pure envy!...

DesiGuy1981 would be lucky if could get 2496 Kbps;  if
he were the one with a 3Com, i'd recommend him that he
tries an UpStream band starting with bin 6, 7 or 8 and
ending with bin 14.  This should limit the UpStream
signal to 256 Kbps or so and then, maybe, he would be
allowed to dream of a DownStream speed of 2496 Kbps...

I expect the DownStream starting bin to be somewhere
between 32 and 36 and i find it even more improper to
guess what the ending bin should be but lets put it
in the 70 to 248 range.  Most unfortunately, your own
DSL signal doesn't compare with that of DesiGuy1981 so
i'd rather not draw definitive conclusions from future
tests:  i've learned to be carefull with predictions, not to
mention i found no gain/bit-loading CLI commands neither.

:hmm:

I suppose a Bell technician wouldn't raise his profile
unless there's a strong basis to request it anyway.

Fingers crossed...

:uhh:]]> http://www.dslreports.com/forum/remark,20453699 Thu, 08 May 2008 20:19:28 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,20453420 dslgr : @Bicephale first of all, I would like to thank you for the comprehensive post you've made above.

I can see your excitement for the USR's tweaking capabilities, as it matches mine, the first time I realized I could "play" with my line and try to get it to reach its limits.

Sadly though, my initial expectations weren't met and that's why I asked you in my previous post if there was something more besides tone selection, that could have slipped my mind.

I agree that tone selection is a nice feature but imo it can't compare with the tweaking options the GNet, for example, has to offer, which you are very familiar with, as you made the best out of them.

From what I gained from my experience, there's not much tweaking you can do and benefit from it. It's straight forward really, you just select which tones to use and I have "played" both with the cli --tones parameters and with the GUI too. Eventually I realized that besides the extra parameters, it gives you the exact same results.

Reading that the cli command lets you specify the starting tone used in the upstream and downstream direction, and the number of tones in each, my mind went at once to spectral shaping. And with spectral shaping I mean something like that. Unfortunately there's no such option, or at least I couldn't make it work. Regardless of the bitmap I sent to the router, it just masked some tones and didn't change the spectrum.

The only use I could find for the tone selection feature is if you have some kind of RFI which you can't avoid and which hits at random time and in specific frequencies. With tone selection you could exclude those problematic tones, so you won't have to worry if the RFI is on or not, leaving your line steady in all cases.

In your post, you mention another benefit from it, which I hadn't really considered and that's the reduction of internal crosstalk. I probably didn't think of it because I value the upstream rate too much (and it already has a hit, as an annex b line, and from my crappy NT1 device), to sacrifice it for a bit more downstream, but I would be more than glad to give it a try first chance and present you with some results.

In fact, if you like, you could give me specific parameters you would like me to test (like specific tones, ranges and such). The only problem is that I can't really give you longterm statistics (such as crc errors in days uptime) because unfortunately my line is not so stable. With the ST I will probably have a drop every one or two days, which doesn't really bother me, but with the USR, that number goes up to 4-5 a day, so you see I can't collect enough data.

Those are my thoughts for now. I will be waiting for a response while getting the USR out of the drawer. Hope there's more to do with it.

Greetings from Greece and a fellow tweaker.

Thank you.]]> http://www.dslreports.com/forum/remark,20453420 Thu, 08 May 2008 19:01:33 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,20453370 dslgr : @DesiGuy1981 apparently, there was no positive outcome from the changes you've made with DMT. Unfortunately, it is a tough situation, taking into account the very high attenuation your line has, but I understand your efforts to get the max out of it.

The only thing I can think of, is to ask from your ISP if they can increase the Remote Tx Power, from their side. Doing so will give you another boost for sure, considering that there should be at least another 4dbm room for increase (in order to reach 19dbm in total).]]> http://www.dslreports.com/forum/remark,20453370 Thu, 08 May 2008 18:51:11 EDT Re: SpeedTouch 516 Tweaking :) http://www.dslreports.com/forum/remark,20452086 Bicephale : Good luck with your week-end tweaks!

Thank you very much for offering some feedback about your
3Com USR-9107:  Spectral Shaping made on a per-tone basis
and via a GUI as above certainly stimulates my curiosity!!!



The US Robotics SureConnect 9105 CLI Command List refers
to some "--tones" parameters but i'll confess that i find
the GUI a lot more intuitive;  DesiGuy1981 would be able
to explore real options should this be available to him,
no doubt.  I've been hoping to meet with a pioneer who's
willing to test the 3Com's Spectral Shaping abilities for
quite a while so here's how that's supposed to work.  In
short, the idea is to use as few UpStream bins as possible
so that the output level will generate less local noise;
it would seem even better if you could adjust the bin's
weight on an idividual basis as well but it will have to
do...  My post titled "GNet Tweaking" illustrates how one
can control the DownStream/UpStream speeds on his GNet:
