I'm the same house as silverwolf on that weird broadcom exchange.

interesting to see you have 17a on your line.

broadcom chipset, on the new firmware, pretty brave. very few are managing to even sync on one of them.

your stats would indicate SRA isnt on, so that is interesting.

hio77:

this brings another question for Brent, has Seamless rate adaptation been implemented to chorus's network now?

fyi, realtime updates are in dating back to 5.22, and the max/min has been in since 5.51. just hasnt really been useful, until now if SRA has been enabled on chorus gear recently (which looking at your results, maybe it has..)



I struggle to keep up with all the activity in here!

No, we dont use SRA.  bitswaps could cause the max/min being seen though.

Ha, it's a pretty active thread indeed.

Didn't know bitswap actually altered synced speeds.


I didn't think so, but considering the graphs and a Vodafone guy I talk to often claiming he had it, was worth a second ask.

Guess it's just saving min and maxes a bit better now.

Min on the 5.22 was zero and max being current.

The spectrum graph is bits per tone. Bit swaps would alter the bits per tone as it takes/adds bits in/out of tones :)
Didn't look like the sync rate changed, but the graph with min/max didn't show bitrate

was more referring to the comment of his sync rate changing on the fly, which is the second point that made me look at it.

bitswap is one i have often wondered about, in terms of how much of a change it can actually make, ild speculate to assume that the reason CRC rates drop down after awhile is bitswap swapping out where the errors are occurring.

Oops, missed the Forrest for the trees! I was looking at the pretty pictures hahaha.

SRA is definitely not on, so I'm not sure why the sync rate is moving around.
Perhaps it is recalculating while bit swapping occurs, but that wouldn't change the sync rate by much at all...

Can't explain that one!

ild blame the 6.0 firtz OS trying to be "smart" in that case!

AVM have been working hard on making it "smart" and less useful to us tweakers afterall!

I might have been imagining things. Watching it now and the only thing that moves lots is the Attainable upstream value ( the value that is well above the dslam upstream max ), and its drifting by a few hundred K per update.

But thats's probably extracted from the same data used to produce the spectrum graph, so it may simply be reporting the medium limits irrespective of the hardware at the end.

US Sync has been stable at 1-bps less than DSLAM max and DS sync is stable at DSLAM max.

So probably sense-confusion on my behalf making a bit of red herring.

AH your talking about attainables again!

attainables dont mean alot.. also depends on where you pluck your attainables from, i can get 55192 from the fritz webui, where as i get 69453 from the telnet function (which i see as a more expected result anyway.)

That's my understanding of how it is supposed to work. It shouldn't affect the overall sync rate as bits are swapped from one tone to another. It should reduce errors by moving bits off of frequencies that are experiencing crosstalk or interference.

yep, exactly how i understood it, which is why when mention of sync changing due to bitswap made me consider if we are missing something.

Hi Team

With full flavour. Havent posted recently but care to have a nosey at my stats to see if there's still a possibility of improvement?

Cheers

certainly not a bad line, your still running that dodgy 0 attenuation firmware though.

DLM-1, 17a with next to no errors. i assume i few days of uptime?
