[AusNOG] Highest ADSL2 internet connection speed

[Chris Pollock]

Yes, exactly - not difficult to get full speed at sub1km, in fact it's
expected - every single successful order we've placed has been in
deployment class 9q.
 
My question for you MMC is, what's the greatest distance over which
you've achieved full speed per pair?
 
I've got a single pair on a HN402 sync'd at full speed travelling over
1.9km of copper.  It's interesting, the expected tailoff vs what we see
in the real world - the equipment seems to be capable of better speeds
than expected.
 
Cheers,

seen, pairs required to bond for 10Mbit over certain distances etc?


	SHDSL is different to ADSL in terms of the deployment classes
and how they're done.  

	The limitation about speed is much more related to the
deployment class than what's technically possible.   Our EFM equipment
quite happily maxes 5.7Mbps/pair when allowed to, but as distance
increases beyond 1km, what speed you're allowed to do drops.

	We have many pairs which are running happily at the 5.7Mbps/pair
maximum.  So delivering 10Mbps within 1km or so of the exchange is
fairly straightforward.

		It doesent beat your 24xxx down but 2.69 up is very
good.

		
		It would be VERY interesting to see what it synced at if
you turn Annex M mode off - Annex M 'steals' downstream channels and
makes them upstream channels, and it is the lower frequency channels,
which contribute most to the aggregate, that are most affected. Turning
off "annex M mode" is likely to push at least 1200 kbps or more back to
the downstream - and take the record!
