New toy arrived!
« on: June 04, 2013, 05:34:43 PM »

I haven't posted for a while but a new toy arrived earlier today which some may, or probably may not, find interesting.



I haven't had a chance to play with it yet but when I do I'm happy to share an findings on my own FTTC/VDSL2 line if people find it remotely interesting.

Me too.

Given time to play with it 'sufficiently', it will be interesting to see exactly what information it can provide & also to see how any empirical data compares with that obtained via an unlocked HG612 modem.

Are we to assume it has the very same module/modules as provided for use by BT Openreach engineers?

Meow! (Bellowed).

I hope that box contains an HST-3000c, SIM(s), etc and isn't just an empty cardboard carton.  ::)

I should hope so otherwise I won't be able to do my job very well  ;)

Just for you BC..



Waiting for the course before I start tearing open bags of cables/dongles etc but I've had a quick look through the various menus and options.

Very nice.  ;D

Now when you start 'looking into it' more deeply, I'll be interested to know the version of the SIM that you have fitted. I am aware that there are a number available for ADSL/VDSL testing, each with different chipsets. IIRC, Infineon and Broadcom are two of them . . .

SIM - "HST3000-BDCM-WB2 ADSL/VDSL Bonded and Copper (up to 30 MHz) with Broadcom Chipset"

Seems to consist of: Copper, xDSL, VDSL bonded, ADSL bonded and Ethernet TE.

Hope that helps.

Ah, thank you. That is the sort of precision I appreciate.  ;)

Searching through my library I found a JDSU document, dated May 2011, from which the following specification snippet has been extracted.

I'm sure the user manual, and other details are easily obtainable, so if you or any others on here want to read them and want specific tests carried out, and results documented, I'm happy to use my line as a test platform so to speak.

On a personal note I had/have an issue with my flashed HG612 showing a horrendous amount of CRC errors (documented ages ago on here) so I'll be seeing if the HST3000 mirrors those results.

Off-topic: You have awesome carpet (same as mine) :D

On-Topic: My line shows a high amount of CRC when on fast path when using a HG612, we are looking at 20/30 per second over 45 minutes. Though when the engineer tested with his JDSU the CRC were far less than 1 per second over an hour time frame. So you may have the same experience I've had.

I appreciate they're not the best images ever but they'll have to do for now. Those are the seven screens/options available under the "VDSL Modem Emulation" test. I'm going to leave the JDSU in the case now until my course and then I'll post more images.

Now that is interesting.

It seems that the data for the usual screen that some of us have seen:-


actually comes from the U1 & D1 bands (more or less & allowing for a slight SNRM variance).

Did you get chance to grab your stats from the HG612 for comparison between the two pieces of kit?

What 'caught my eye' is that the attenuation is also quoted at 1 MHz, 7.7 dB for Griff's line.

Spent the last two days on my HHT course. Unfortunately (for the sake of this forum) it was all PSTN based.
