[AusNOG] Highest ADSL2 internet connection speed

[Matthew Moyle-Croft]

Darren,
When we provide a DSL service you create a line profile.  This determines a lot of things about the line and can greatly affect the speed.  eg. how much SnR margin to cope with noise.

I suspect you're seeing a line which is sync'ing to the maximum of it's profile (24575kbps being 1kbps less than exactly 24Mbps which is a common limit applied).

So, the maximum can be tweaked, but the highest != best.

Hi Paul,

Now that would be decent broadband, but I am guessing you would have to be pretty much in the rack with the DSLAM ;)

Thanks everyone for your ADSL2 stats.... I'm winning so far :)

Hey Noggers,

We were doing some maintenance recently and I asked my team what would be the fastest ADSL2 connection speeds they have seen across our customers.

Here is the fastest we have seen...

24575/1020 Kbps

The actual attainable rate was 27008.

Amazing.

Location...... not Metro.......

Anyone else seen higher ?

(breaks out the old spectrum interference model)

FWIW, the protocol maximum for ADSL2+ that you should see on sufficiently short and isolated loops is 28188 kbps - so you still have some headroom to be beaten!
