ASSIA - the cause of performance problems?

Recently my Bryanston ADSL line - which I've had for years - has been syncing slower and slower.
From a comfortable 4Mbps with 12dB noise margin, I'm now at 2.5Mbps and 7dB. Swapped routers, no difference.

I was reading up about ASSIA, and it seems increasingly clear that it is the root cause of the slower syncs. Why then would Telkom not disable it, or at least give subscribers the option to use the "Fast Path" setting?

Presumably there is some real or imagined benefit to Telkom of running ASSIA in Interleaved mode? Fewer callouts? Lower bandwidth usage? Do some Telkom ADSL customers actually get better performance and/or stability with ASSIA in Interleaved mode?

How do we get Telkom to listen to their many disgruntled ADSL customers, and give us the option to change settings?
 
I have seen lower CRC errors on interleaved mode than fast path mode.

I think you have some dodgy degrading copper in your house.
 
Yeah, my thinking is that your noise margin would be higher if it were just ASSIA.

I view ASSIA as a triage procedure to keep you going until the underlying problem is identified and sorted, hopefully without you being aware there was a problem. Unfortunately it seems some of the techs reckon it's easier to identify the problem when the line finally dies.

The impact of ASSIA on gamers iro of latency is another topic.
 
Okay, so 45 minutes later, and some unwanted and incorrect redirection of my call from service to sales, I asked Telkom to change my profile back from Fast to Faster. and my line is syncing at 4096kbps, still with 7dB noise margin!
Thanks for nothing, ASSIA.
 
My line was recently flagged for ASSIA, is indicated by my ISP. I have a 4Mb line, but synch, speed test and download at and average of 7.4Mb

So no complaints here.

Your line is still on interleaving, I'm assuming, what is the interleaving value on your router?, you could also have copper issues

They changed my profile as well, then assia took over and adjusted my interleaving value, but still synced @ 4096. few days later my line dropped and I was syncing @5120Kbps (albeit the line is stable, but ping wise, 35-70ms depending on the location of the server obviously).

200m as the crow flies. iSAM was recently upgraded to 40Mb capable. Pity my ISP does not agree and claims only 4Mb is available?!?! I stood at the exchange while the were upgrading it. Made some good contacts too.

Well I'm saving money so will not be officially upgrading.

Note: I have a Capped Business account with WA. That does help.
