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!)
