Ooh. The reverse of the current topic! If memory serves, Burakkucat and I were talking about this some while ago, and Burakkucat might have even discussed trying it out for me back then. That was for G.992.3 with PTM. If only PTM were actually supported by BT or Talktalk over ADSL2 then it would be fantastic for us troglodytes as it would instantly get us back the wasted 10% of speed (>53/48 slowness factor) that we have simply lost with the madness of ATM. The ATM slowdown will be far far more than that if sending / receiving short messages, in fact easily 50% speed reduction.
