[AusNOG] Highest ADSL2 internet connection speed

[Chris Pollock]

Alright, EFM, here we go!
 
You're right, it's 5704kbps per pair symmetrical maximum speed in the
top deployment class with 2BaseTL EFM.  In the lab I've done up to
45632kbps symmetrical on a Hatteras HN408.
 
Real world, the largest I've done is 22816kbps symmetrical, but that's
not because we've aimed for more - there's been no demand for past
20mbps of EFM.
 
Cheers,

	Righto, annex M going off tonight for a shot at the title!

	 

	Would be a pointless victory if the synch wasn't stable for more
than a few days, which I wont be testing,  but interesting experiment on
a good line I agree.

	 

	On the note of Synch speeds, What will be interesting is the
attainable synch on some upcoming EFM SHDSL Circuits we have going in.
Theoretical Maximum should be 5.7/5.7Mbit per pair so will see how we go
with Standard 4 Wire Synch.

	 

	Anyone have any feedback on EFM Circuits and speeds seen, pairs
required to bond for 10Mbit over certain distances etc?

	 

	Cheers,

	Marcus.

	This is on a Linksys/Cisco WAG 160n

	 

	Status: Up 

	Downstream Rate: 23855 Kbps 

	Upstream Rate: 2691 Kbps

	 

	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!
