In my grotto I have a Huawei HG612 Home Gateway and a Planet VC-230N. The latter device is currently configured in CO mode with profile 17a.

If it would be considered worthwhile, I could flash each of the various firmware images listed below into the HG612 and record the basic statistics once the device has synchronised with the VC-230N. Each test would be carefully controlled to ensure that they were all carried out under identical conditions.

The firmware images that I have selected for testing are:

• The original Asbo unlocked
• The Asbo unlocked, with the new BLOB
• The Wolfy unlocked, with the GUI

Do fellow Kitizens think it would be worthwhile exercise?

Indeed it would  8)

Thank you. Obviously my testing would not be as extensive as that which Asbokid could perform with his Huawei SmartAX MA5616 MSAN    but it should provide some metrics for comparison.

  Sounds really helpful especially if you have enough cable to give some typical attenuation between the devices.  I would not have thought that the trouble that Asbo went to with baluns would be needed as you be using the same device with any impedance issues fixed, and just changing firmware.

I agree, it looks like very useful research.

Thank you, all, for your feedback.

I've put this little project onto my 'ToDo' list and now will try to find the time to action it.

Finally 'the time was ripe' ((C) 1980s Sir Humphrey Appleby of Yes, Minister and Yes, Prime Minister fame) and some testing was performed.

The HG612 firmware images tested were:

(1) Original Asbo Image Unlocked.
(2) Asbo Image Unlocked, With New BLOB.
(3) Wolfy Image Unlocked, With GUI.

The VC-230N Configuration ('One Port DSLAM'):

Profile 17a, Annex A.
SNRM set to 6 dB.
Interleaved (8 ms).
INP set to 3.
No rate capping.

Local loop length == 1.5 metres.

Testing Procedure:

VC-230N powered up.
After 5 minutes, HG612 powered up.
After 5 minutes, HG612 GUI statistics gathered,
                        HG612 CLI statistics gathered,
                        VC-230N GUI statistics gathered.

Attached, below, are four files -- showing the VC-230N's configuration and the line_stats_p obtained from the HG612 with each of the firmware images, listed above, installed in turn.

Attached, below, are the corresponding first HG612 GUI pages for each of the firmware images tested.

Finally the ASCII text data from the HG612, for each of the firmware images tested, can be supplied via e-mail to anyone interested.

The data collected was the output returned by the following nine xdslcmd lines --

• xdslcmd --version
• xdslcmd profile --show
• xdslcmd info --vendor
• xdslcmd info --cfg
• xdslcmd info --stats
• xdslcmd info --show
• xdslcmd info --Bits
• xdslcmd info --pbParams
• xdslcmd info --linediag

Thank you B*cat..    I has headache & since I have to be up early tomorrow, now is possibly not the best time for me to be looking at stats in depth

I shall give closer strutiny to pbParams and graphs when I have a clear head,  however I cant help but notice both of Asbos give a similar attainable rate on the HG GUI.  The 3rd shows a better SNRm and therefore higher attainable rate.   I do note that the 3rd upstream attainable appears to be capped at 51316?

[burakkucat]

I do note that the 3rd upstream attainable appears to be capped at 51316?

That is very odd. It is certainly not something that I had configured . . . The VC-230N was (and still is) set to 'No rate capping'.   

I'll send you a ZIP format file of all the data, via e-mail, for your consideration on another day -- when there are less empty wine bottles a-rolling across the floor, chased by kittehs . . .

Finally the ASCII text data from the HG612, for each of the firmware images tested, can be supplied via e-mail to anyone interested.

I'd also be interested in a copy of the zip file containing all the data, please.

[burakkucat]

How could I forget that beak?    My tail still remembers the last time that it was tweaked.
