The joke wasn't needed really was it?, the few replies came across as if I was being thick and not seeing something obvious, when in fact the question asked was valid and did not warrant a response I got to be honest.

I know that my DS attenuation, measured via the JDSU, is/was 10dB.

That doesn't look healthy to me.

The power readings may be suspect, but if not could account for the low speed figures. On 10dB attenuation you should be connected at 40000/10000. As a comparison, I am on those sync's, (according to the JDSU and a never-flickering IP Profile of 38717), with the JDSU also giving 17dB attenuation at 0.6km compared to you.

Doesn't appear to be reporting some of the figures correctly but the speeds look OK.

Errors looks a bit nasty but depends how long you've been connected non-stop.

Ahh.. that's makes more sense, MHC.

I managed to source one of those unusual JST-XH connectors and fashioned an RS232 cable out of it that fits the BBU port. There's a (hidden) option for testing the BBU port in the /bin/equipcmd tool, but it still doesn't work!

It was only connected for about 2 minutes before the screenshot.

I had issues back in January which resulted in two OR engineers attending (trainer and trainee). They spent four hours checking all the internal wiring for faults but found none at all yet everytime they connected the JDSU and ran tests the errors would immediately appear and increase during the course of the test. I seem to recall each test taking about 10 minutes, possibly 15 minutes.

I was told they had no explanation for the errors and after spending half the day with me they left saying they'd done all they could.

Hi Griff_90..

Thanks for posting your stats (and for offering to take a photo of the PCB on the 2B).

There is a dearth of data for VDSL2 Profile 8c performance in the UK. Pretty impressive figures you're getting there.. I think yours are the best I've seen..

Any chance you would get a telnet shell on the Huawei and issue "xdslcmd info --pbParams" and "xdslcmd info --linediag", to get all the stats..

The output from the latter command runs to several thousand lines of data, so only good for copying to http://codepaste.net/

cheers,
asbokid

Have you managed to understand the power levels?

Griff_90 has published a screen shot with a reading of 5.2dBmV

Roughly converting 5.2 dBmV to mV gives around 4mV ! Power levels will be well down in the microwatt region!

Hi asbokid,

Cheers for your helpful guide and comments.

I'd be happy to get the relevant information via telnet later this afternoon and post back.

Is the only way in, after changing the firmware, to unplug and connect direct to the LAN2 port?

Or can you do it when hooked up to LAN1 via the hub?
