1 edit | SpeedTouch 516 Tweaking :) Time for some Researching and Playing (trial and error)
Download
»www.2cent.de/dmt/st7/dmt.zip
If you downloaded the new firmware this wont work.
open it up.
Very nice piece of software, better than Alcatool.
1)
if you want to monitor your line stability, click on GainQ2 and click Start on SNR-Minitor Interval. After a while you will see a white line going threw the graph. I Dont really know how much it should go up and down but the less the better i guess.
2)
Go to special Misc option and enable the hidden 4 and 5th tabs.
I've noticed if i change the Target Noise Margin and hit apply / resync
it wont work.
If you click Option 2 and then change the Target Noise Margin it allows you to apply/resync and it changes.
Guys that don't get the full 5megabit or attainable is close to 100% can you play with it and post your results?
I am getting around 70% and when I set it to minimum I get 98% 5056 sync. So going up should allow you to increase sync but it will be less stable.
3)
I am not sure what Channel Characteristic. But it shows you an estimated loop length which is pretty cool.
Post your results  | |

| Re: SpeedTouch 516 Tweaking :) Looks like a cool program.
To bad I cant run it since I'm using a router. I'll have to configure my router so I can access the modem, but i don't really feel like changing all my network settings lol
I'll have to see,
Thanks

| Anyone brave enough to try the last two tabs(advanced options)?
The 5th tab has Power options, I wonder if it will convince the DSLAM to increase the transmission power levels.
Don't want to try them yet, just monitoring the modem to see how it compares with the SpeedStream 6520 it replaced.
So far, some impressions :
- a nice option, you can enable and configure time server options. It takes effect immediately, and synch modem time with the selected net servers. (6520 did that after being up for maybe a couple days, no option to configure the service.)
- I like how it keeps stats of total data transfers right on the main modem stats.
- also like how you can 'name' the computers on the network, instead of simply having MAC addresses.

| Here's a snapshot of the current stats on my modem.
Have 3 Mb/sec service, was Fast path for 11 months, then dropped, and after one week of Sympatico support calls came back, but interleaved.
One possible good thing I observed - the relative occupation on the Downstream seems to show 53%.
Assuming that 70% RCO (like shown on TilhasBB's image) is normal/acceptable, maybe I possibly get 4 Megabits from my line?

can you rerun the program and dont start the snr monitor. that last box on the bottom right should give you an estimated loop length. what is it?
Your the perfect jinny pig
can you go into Modem Options and play with the Target SNR. Raise it 4 points hit option to then resync see what the % occuation is. and play with it post results
Riazg> Yes thats the link. Bicephale found it i belive.
Hummmm.
I am having some internet problems.
I would not lose sync but my internet would stop working for 1-3 seconds. msn signs out and my downloads stop then comes back.
Anyone else have these problems? | |

| Re: SpeedTouch 516 Tweaking :) Will do in a day or two, but right now I just want to observe the modem and compare to the SpeedStream. Got disconnections with the SS, although they were short and mostly I got the same IP address.
The 546 doesn't seem to have disconnected at all yet, uptime is 8h20min.
Once I observe it and know how it works better, will play with the extra settings.
How about the 'Transmit Power' option on the 5th tab panel? I have a feeling that it's intended to raise the DSLAM output power 9send a request for that anyways). That could help people with large attenuations like mine.
Yeah, I know 5 Mbit/sec won't happen on my line, but maybe I can get 4 Mbit.
3 Megabit service worked well for almost a year before I had any problems. The wire length is about 4 Km according to Bell support people. DMT shows a vague estimate (3.8 to 6 Km) for wire lenght.
EDIT : used the TX Power option on 5th tab and a DSL resync. Seemed to raise the DSLAM transmit power from 18.5dB to 19 dB.

1 edit | Had missed your post - Big thank you, as the thread you linked to is VERY informative.
Starting with how to do the SNR tweaking, it's not very clear in DMT.
This will get me started in the right direction.
EDIT :
Followed directions on the thread linked above. Used value '10' for modemoptions 00.
SNR just before applying setting was 8.0. After resync, came back at 15 dB. Now got to wait a few hours and see if it is stable.
Seems best to use number values for register 00 than the slider (which has no number values, and is more inaccurate, imo).

| Re: SpeedTouch 516 Tweaking :) The higher your getting your SNR the lower your attainable rate. your just increasing the rejection rate.
aka. you put a filter and anything lower than X amount won't even be used so your SNR seems higher because its rejecting all the ones that dont cut it. So I would increase the SNR just high enough so your attainble is around 85%-90% leave some head room. | |

| Re: SpeedTouch 516 Tweaking :) In my case, what I am trying to do is find the highest possible SNR, with the best Occupancy on the line.
The setting I used improved the SNR, and the RCO is now about 48% (attainable being 6266 Kb/s).
Once these are tested for stability, I could approach Sympatico and request that they increase my synch rate for testing purpose. Not a full 5 Mb/s, but hopefully 4 Mbit might work for me... Showing them a good occupancy potential is crucial to get it.
These current settings have been on for about 5.5 hours, and the SNR ranged between 15 and a low of 13 dB. Good numbers for my line!

Received CRC : 4
Received HEC : 4
Transmitted FEC : 42
Transmitted CRC : 2
Transmitted HEC : 0
3811 - 6269 Loop Length hehehehe
Your on Interleave ouchh...
Attenuation at 52 SNR 14.
K can you try lower your SNR a bit but keep the attainable above 5600
Because I know for 5Megabit at 100% you need an attainable of 5532 atleast.
Also pump your Tx power from 19.0 to 19.5 (max her out)
Attainable line rate : 5532 kbit/sec
Fast used Atm rate : 5056 kbit/sec
Rel. capacity occupation : 100
How is your setup now?
modem to phone jack directly? (how long is the phone cable)
By the way USE the new phone cable you got with the modem its quite good. As good quality as the old nortel one I had. | |

1 edit | Re: SpeedTouch 516 Tweaking :) The are some errors, FEC mostly, yeah. The wire is pretty long here, 4 Km according to Bell folks.
I had Fast path for 10 months, until November. Waited a month before calling Bell, we had so much rain, everything was soaked all over the place, etc. Finally, after a week of headaches and daily phone calls, got stable 3 Mb/s synch back, but interleaved.
Speeds have been good, so I did not complain.
Relative occupancy of 100%? Don't think the Test Centre folks will like that, lol. I plan to test and stabilize things, then ask for an increase to 4Mb/s, possibly.
Wiring here is pretty special, custom made to try get the best DSL signal. I posted some pictures and description on this thread in the Sympatico forum.
Basically, phone system split at the demarc, straight CAT5 run to a dedicated DSL jack. Modem provided 6 ft flat cable between modem jack and dedicated DSL wall jack. Other home phone wiring double-filtered right at the entry point.
The phone cord that came with the SpeedTouch is indeed nice, the best one I have seen so far. A very satisfying click, tight fit when it connects to the rj-11 jacks. I like it!! 
TX power - I tried placing the slider on 'MaxPower', but then you have to hit 'Modify' and it didn't seem to stick. Would be best to use a bit value on the boxes, but I don't know which to use.
Did the slider work for Max power for you?

| Re: SpeedTouch 516 Tweaking :) Thanks for the comment, I like the wiring too. Was worth it, a lot of GB came down that path, lol.. 
Came up with something that could help others. Bicephale had mentioned heat as a bit of concern for the SpeedTouch models. Then I did some reading on this thread.
Lifted up my 546 and it felt very warm on the underside, probably one of the chips is located on the underside of the circuit board and giving off heat.
Solution, used a couple of paperclip boxes (handiest object around atm) to raise the modem up a couple centimetres.
The heat I felt first time checking is no longer there - I think this might be a good idea, raise your modem to allow more airflow into the base holes.
Someone in that thread suggested using 4 plastic bottle caps, and boy, that should work just nice, they are the right size.
Tried reading the DMT site, but the little info there is all in German. The ThinkBroadband UK forums are probably our best bet, folks there have been using DMT for a while.

Same situation in Canada so far, so maybe we should try the UK variants?
The UK 546 model page includes version 6.1.4.6.
So you have been playing with the firmware back and forth?
How did you install the new one? Using the tool on the CDROM?

I take no responsibility for anyone who attempts this. I did so nobody breaks it opening it the wrong way.
Push the power button in. Remove the two screws, DO NOT try to pry it open. simply PUSH the top part and it will slide back then open.
You dont have to open yours, I already opened mine for everyone who's curious to know what chip was inside.
By the way, upon careful inspection I am not to impressed. look in the back on the bottom right it looks as if someone sprayed desolder and didn't take it off properly. I guess that sticker made in china doesn't lie. | |

2 edits | Re: SpeedTouch 516 Tweaking :) Ok, I am now back online, with the UK 6.1.4.6 version (found on this page).
Uff - followed Steve's instructions and links carefully, saved my configuration before the upgrade (Saves a TON of time reconfiguring it, just takes a sec.).
Having been burned by various motherboard BIOS upgrades in the past, it was a bit of a tense moment. All worked well, and I am happy and relieved.
First impressions :
- my Attenuation improved by 1 dB (now 51 dB).
- this version supports DMT, I wouldn't use a version that didn't.
Thanks Steve for very detailed instructions and links.
Tilhas, thanks for showing us the internals of the modem. I think the 546 might have an extra chip on the underside of the circuit board, possibly the 4 port ethernet chip.
The bottom of the 546 gives off heat that really seem to indicate some busy IC there.
EDIT : DMT support and SNR tweaking seems to be flaky on this firmware - I might have to restore the original.

But the newer UK firmware behaved oddly with DMT - when I first opened the program, it would show the stats and graphs properly, just like in the 6.1.0.5 version (default that came with modem). Click on Refresh, and the graphs would no longer be there - data wouldn't come from the modem.
Tweaking SNR was not working well either, so I had to give up on my new Brit firmware.

The red circle on the left side of the image does that mean im on interleave?

You know the simplest way I can see is.
Split the phone line from where you have it. connect the modem. then run a long ethernet cable to your pc.
Try removing interleave now and see if its stable if not run the ethernet wire shouldn't cost more than 10~15$ | |

But my question is it really worth it to move it in my office? I like where it is now? Was that really a big improvement on my line?
I have already e-mailed my isp about telling bell to put my on fast-path, They should be ale to put me on there without any problems.
I think the reason why they put me on interleave is because I was getting low upload speeds but after some testing I found out its my isp and not something else.

canada | Re: SpeedTouch 516 Tweaking :) WOW
I always have my power cables running along the ground and have the phone cable going on top of the table to the modem. I guess it wasn't just good practice/paranoia | |

| Re: SpeedTouch 516 Tweaking :) Well im talking about the actual power cables that would be IN your wall. I have that 1 wall thats not finished in our small utilities room and I just unwrapped that and a few other phone cables there were near the power lines and it made a difference.
I'll try to post a picture later if I remember

| said by bryanviper : Just from moving those cables that are in the basement which I thought were not even tied in to my office line since I'm on the top floor of the house. Cant believe that doing that made a decent difference....wow Yes, it makes a difference. Both are electrical conductors. With current flowing, a magnetic field is created. This could have a significant effect on data transmission. By separating the wires you are separating the magnetic fields and preventing them interacting.
quote:
EM Interference
Electromagnetic Interference – when metal wires carry electrical signals of any strength (telephone and network data is actually very weak electrical signals), they generate a magnetic field. Similarly, whenever a wire is present inside a magnetic field, electrical current is generated in the wire. This means that two electrical wires next to each other can interfere with each other, because the magnetic field created by one wire can affect the electrical current in the other wire. The stronger the electrical current, the stronger the magnetic field and the more interference the wire generates. EM interference becomes problematic in telephone and network wires because of the weak nature of the signals that usually travel them and because of the great distances the signals must usually go.

Your getting 5megabit on the dot
Your distance is far bettween 3188 - 5672.
Your stats show you can keep the 5megabit. But I dont like the number of errors your getting.
How is your setup?
Modem to Phone jack? (Phone wire length)
How many phones do you have connected?
Can you try the modem at the demarc point and post another screen shot. If you can't find your demarc point, disconnect all the phones resync the modem and post the results. Also if you can try another location. | |

| Re: SpeedTouch 516 Tweaking :) I was about 30' from the phone jack to the modem, so I hard wired a cat 3 cable from the existing jack over to the modem, and put in a new jack.
I have 4 phones connected. (all filtered)
I live in an apt, so I can't get to the demarc point.
I disconnected all my phones, and re-synced my modem and ran the tests again. | |
