Look at figure 5 on this ericsson PDF on vectoring.

The graph shows performance on the 17a profile, with & without crosstalk, and with both crosstalk and vectoring.

That pretty much shows that 17a will top out at 100Mbps, for the shortest lines, with crosstalk present (ie realistic, with other subscribers). But without crosstalk, the actual bandwidth seems to get as high as 170Mbps.

Figure 6 hits a top speed of 100Mbps, but the write-up shows the test equipment hardware they used in that test is the thing that limits throughput.

To my eternal shame i cant get putty to do owt, i log in to the router then i can get no further.

Once logged in with user name admin and password admin, you should see a ATP> prompt.

Obtain a busy-box shell, by typing sh and press the Enter key. You should now see a # prompt. At that shell prompt, you will be able to enter the various xdslcmd commands. Start with xdslcmd --help.

When done, exit the busy-box shell with a Ctrl-D or exit. Then exit from ATP> back to PuTTY.

You are a star, thank you.

From that we can see that you are still on the original 8c profile but, due to a short D-side pair, you are seeing effectively the full 40/10 Mbps. Once on profile 17a and with the cap removed you probably will have excellent down- & up-stream speeds.

Hi All,

This is possibly the wrong thread, but it IS related to the Huawei HG612's line stats.

I am currently testing new scripts that continually poll the modem for its SNRM, sync, error count etc. & converting the stats into graphs.

I am a Windows user so am trying to do all this via a comination of Windows batch files & Linux scripts.

I have been hervesting the mosem's data every 2 minutes by running a batch file via Windows Task Scheduler.

It works, but annoyingly pops up a CMD window every 2 minutes.
I think I have exhausted every avenue to do this in the background to no avail.

I found a good Windows cron program that does the trick (z-cron), but only every 5 minutes.
I really need to obtain the data every minute (or less) to make it truly meaningful.

FYI, just to loosely stay on topic, example graphs for my own connection can be seen here:-

Do any of you know how I can get Windows to do this silently, or point me toward some FREE software that will do it for me?

Paul.

You mean via plink or extraputty, for example?

No, I have tried Plink, but can't automate the login when using the HG612 (but that's a different matter).

What I am looking for is a task scheduler that can run any program or batch file silently at predetermined intervals of 1 minute or less.
I am currently accessing the modem directly with no need to log into it at all (via a Windows version of cURL).

Using cURL, I am accessing various hidden modem URL's to get all the data for the stuff you can see in the WAN webpage.

Use the Start command to run a bat file minimised - start /min file.bat

ISTR someone cracked the encrypted logon method a while ago - wwwombat perhaps?

Nope, didn't work.

With the start /min as an argument in task scheduler - nothing happened at all.
With it all in the command line, it just caused Winamp music player to pop up!!!!!

Back to the drawing board.

Not quite sure what you mean about the encrypted logon method.
Are you referring to automating PuTTy access, or simply accessing the modem's user panel?


Paul.

I used a program to convert a batch file to an exe years ago but can't remember the name of it. This one looks like it will do the job though and is free.

Autoit might be a better alternative to batch files but I haven't got around to trying it yet and there might not be much point now you have cracked it with batch files so to speak. Good job, I look forward to the release.

One thing I prefer is to have a max of 4 pics per montage, then I can flick through the images to compare them in the picture viewer without them being "shrunk".

EDIT
pycron can run stuff every minute.

I vaguely remember using cygrunsrv from Cygwin to run a network daemon (sshd and maybe others). There is a port of the cron daemon for Cygwin which reportedly works properly. [1] Amazing in itself!

If you didn't mind being rude to other processes, you could hack together a little C program that runs ad infinitum in a loop, doing nothing more than clock-watching. "At the third stroke", it would execute your data harvesting script using the system() function [2], or something similar.

Apparently, the proper way to natively do it in Windows is to use some sort of timer from the SetTimer API. [3]
