It is interesting.  Which router is this, Blackeagle?

Its the Huawei Echolife HG532, firmware 2.02t

Ahh.. another one, like the DLink DSL2680TT, based on the Trend TC3162 chipset?

If it's running MIPS Linux then it's eminently hackable, not so if it's running ZyNOS.

Have you port scanned it? Is telnet open?  Any clues on the type of HTTP server? There should be some info in the HTTP headers.

'Stokie' has taken some good PCB shots of the HG532 B1.  Stokie reports obtaining two UART ports on the board.

Its running Linux and I can get to a busybox prompt (thanks to a blog written by your good self Asbo !!)

I only have a smattering of Linux though, not enough to do anything useful really

Hopefully your new modem will turn up today and you can get some stats off of it!

Once Blackeagle has his Huawei HG612 operating satisfactorily, I know of someone who would like to borrow an ECI B-FOCuS!

If you're brave enough to solder the UART port on the ECI then I think I know what commands to run to get stats, I think

Good luck with your new modem and I'm glad it got to you successfully.

Yep, it arrived this morning while I was at work, so wife took delivery 

OK, some graphs, although I think I might need a bit of help interpreting them. 

[Bald_Eagle1]

Hi BE,

You'll sleep better tonight, now that you can knock out a few graphs 

I see that while I had been playing about with the scripts, I had increased the resolution of the SNR graph.

It is now so large that the montage (including --pbParams & --show) can't be attached.

I have attached an amended GRAPH6.BAT, that keeps the file sizes down a bit, so that if required, you could actually attach the montage.

I have renamed it to GRAPH6.txt
Just rename it back to GRAPH6.BAT & replace your original (if you wish to generate smaller files).

[Bald_Eagle1]

OK, some graphs, although I think I might need a bit of help interpreting them.

Right,

Firstly the big red 'V' shape in your bit-loading & SNR graphs for the downstream D1 band looks very unusual.
It would be interesting to see the Attenuation & SNR values from --pbParams.

From the snippet you posted earlier, your Output power levels look a little low.
From that same snippet, your US SNRM level looks O.K. for the actual sync speed capped at 2000 k v the Attainable rate of 9261 k.
However, DS SNRM looks low for a sync speed of 32123 k v the Attainable rate of 41212 k.

On the rare occasions that my connection syncs as high as 32Mb, the Attainable rate is usually only around 33Mb.

It would appear that some noise somewhere is lowering your overall SNR & SNRM levels, thus keeping your DS sync speed down.

As DS band D1 uses lower frequencies (ADSL frequencies plus a bit), I wonder if cross-talk from nearby ADSL signals is the cause?

Also, your attenuation from the Hlog graph looks too high to achieve anything from the highest DS D3 band.
Bit-loading ceases at just over 70dB attenuation

[Blackeagle]

Thanks BE !!

Yeah, I sort of suspected there to be noise on the line.  There was on ADSL2+, particularly evident at night.  However, since I have now discovered the full route of my line and found it runs past four pubs and two restaurants this doesn't suprise me.

Attached is pbParams for your perusal.

On a slightly different subject (but its my thread so I can  ), I have had to set my network up in a peculiar way to get to this stuff.  I.E. I have had to move the router IP to 192.168.1.10 to allow me to access the modem on 192.168.1.1 but I have had to set up everything with static IP's as when left at 'auto' they were picking up two gateways, one at 1.10 and one at 1.1  Suggestions would be welcome as I have only configured a few of the devices and will be getting moaned at when I haven't set the other kit up 

[Bald_Eagle1]

Well,

My modem is still set as 192.168.1.1
My router  is still set as 192.168.1.254

Any PCs I connect to the router (wireless or ethernet) are just set to obtain an IP address automatically.

HTH.

[Blackeagle]

Hmmmm, OK.  Perhaps its to do with the fact that both LAN1 & LAN2 are connected to the router.  I definitely get double gateways with this config and so nothing knows what to use if I leave it at auto config.  Currently a few things are online (including the wife on FB) so can't mess around at the minute, but think I'm gonna set up DHCP on the modem and turn it off on the router.  That should sort it I think.

In the meantime, DLM has changed my sync speed and it is now 34999 with a currently max attainable rate of 42252 with an SNRM of 6.3dB.

[Bald_Eagle1]

That's strange.

All the modem needs to do is present an ethernet connection to the router & then the router should sort it out from there.

The speeds look alittle better. Let's hope that nasty DLM doesn't want them back again.

Where did you manage to get the US QLN data from?

All other connections I have seen (& your first Plink log) show values of -160.00 for the US tones.

My fault !!!  Misconfigured the router slightly when I changed its IP address.

All data is supplied by your scripts so I dunno ?
