Re: More FTTC line stats

Cheers Croftie,

I will give that a go.

I did try it with another couple of BAT to EXE programs.
Some struggled with environment variable settings in my batch file & the free version of one that worked perfectly was intentionally crippled so that it wouldn't work on a different PC.

I am trying to make it as simple as possible for other users to set up as it's bad enough having to download a load of Linux-style utilities, adjust your environment path, store things in a main folder, whilst being able to simply drop the Putty log on to a desktop icon & output to any folder you wish (without the need to install Cygwin or similar programs).

I'm nearly there now though.

I take your point about 4 pics per montage, but I find it simple enough to move around & zoom in & out using Windows Photo Viewer.

It's easy enough to create a montage with 4 pics & another with 2 pics in one operation.
Also, individual pics are created at the same time for more detailed viewing if required.

All the pics in one montage just gives a quick overview as to whether further investigation is required or not.

Cheers asbokid,

I'll have a look at your suggestions.

I am really trying to do this as simply as possible, without the need to install Cygwin etc.

It might have actually been simpler to write a bit of C code in the first place, except it's that long since I wrote any, I have more or less forgotten how to do it.
(& even when I did write some, it was very, very basic stuff anyway).


Paul.

If you don't mind having a command prompt permanently open, then you can easily add a pause to the batch file and loop ad ifinitum... Just use

choice /T:nnn /D:N

where nnn is the number of seconds to wait.

If you want to hide the window as well, then it seems a vbs script can do that for you:

Remembered the batch to exe converter I used to use: Quick Batch File Compiler. Not free though.

In reply to a post by Bald_Eagle1:
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?

Years ago, I started to use a generic web-based application that polled for stats off various bits of hardware, called Cacti. I use it on a Linux server, but there is a Windows version too.

As I was using that, I added scripts to login to my ADSL router and extract the various bits of line statistics. Alas, these were useless for FTTC.

However, as I've now unlocked my modem (finally!), I can redo the scripts to start collecting data again. Looking forward to it...

I finally unlocked the modem, and here are my line statistics...

This was a line that, for the first 2 days on profile 8c, got full 40Mbps but 4% packet loss. DLM intervened, added interleaving and I lost about 4Mbps in profile speed (it was around 34799 according to the BT Speedtester). My line (600-650 metre) should have been able to handle 40 Mbps properly, but I couldn't persuade Plusnet to get Openreach to investigate, as the original estimate was for 30.1Mbps.

When I first changed to the 17a profile, my profile speed returned to the full amount (well, 38716), with no loss of upstream speed.

The line statistics are below, and show a 12dB SNRM. I assume that DLM has set it this high, and this is the reason that I used to have a slower speed with the 8c profile. Shame, 'cos the line used to be perfect under ADSLmax.

It does seem to show that my line is using both U2 and D3.

A high SNR is only a problem if you are syncing at a low speed, in your case it's a good thing.

Even though your SNR is 12dB, thats a good thing since you are synced at the maximum limit, it just means your line has a bit of SNR to spare.

As you can see from the maximum attainable, thats probably max attainable at 6dB. Once the sync cap is lifted, and you ever upgrade to the 80/20 product, the SNR would then drop to 6dB (DLM permitting), and sync as fast as possible, using up all the spare SNR to achieve the target margin set by the DLM, which is set at 6dB by default.

I hope i've explained that right anyway. tongue

Thanks for that suggestion, but it looks a little top-heavy when considering all the other software needed to go with it.

Well, don't waste too much time re-inventing the wheel.
There is already a Linux script available that graphs the stats such a bit loading / SNR / band plan / Profile data etc. (via a manually obtained PuTTY log file).

I am just finishing off a Windows batch file conversion of that script & have very recently added an automated telnet login (via Plink - command line version of PuTTY) that collects the data into a log file & generates the graphs, all with just a double mouse click.

I have also further developed a Linux script into a Windows batch file that runs every 2 minutes (that's what I want the Windows version of cron for) & maintains an ongoing log of everything that is visible in the modem's Status / WAN/ xDSL page.
I am currently using a Linux script (via Cygwin) to graph the data over a user definable latest x No. of hours / days.

I found this was the only thing that convinced Plusnet (Alex R) to get another engineer out to fix my unstable connection once & for all.
Up to that point I had been told that nothing else was necessary as my connection was as good as it would ever be.

It was the really high error count, depicted graphically that swung it for me.
I was getting up to 2 MILLION CRC errors per day, but Plusnet's own remote tests showed the connection as all O.K.
They only really see Sync speed & connection up time.

I don't know how long your connection had been up when you posted your stats, but maybe a graph or two could help in your case?

If you really do want to start from scratch again, just one useful modem URL to "curl" for data is "http://192.168.1.1/html/status/xdslStatus.asp"

That gets the basic data & my batch file calculates a few parts to add it all to a log file that is then used to generate the graphs.


Paul.
