Chris,
FWIW, I wasn't suggesting you were doing anything wrong, just surprised about it. Certainly a big length of 0.6PUIT is going to help.

Not as surprised as I was! It took a few goes at the order to get it right, there's only so many times you can get an 'Incorrect deployment class' message before you start going back to your distance/resistance calculations.
Deployment classes aren't strictly distance based, they're actually on power levels injected at certain levels of resistance calculated over distance; the 1.1km full speed range is based on an average of 0.4 PUIT copper. This run happened to have a large section of 0.6 PUIT as the exchange service area was split for the installation of a new exchange some years ago, and a lot of new, high quality line went in. So that is actually still obeying the deployment class rules, just got super lucky with the cable run.
Cheers,

Hi Chris,
I haven't looked, but I'm surprised you're running 9q at 1.9km. But as I said before, the legal limitations allow us to deliver much less than what the equipment is capable of.
(We've got a range of pairs in a range of deployment classes due to distance at various locations).

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,

Anyone have any feedback on EFM Circuits and speeds 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.

This is a STABLE connection using Internode ADLS2+ Extreme Annex M in York St Sydney
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!
(if you do try this, please get the customer's permission first!)
