Jack --

From all I hear, telcos want the full ADSL, not G.Lite, even if they do start with the lesser speeds to get the market primed. They have to have enough speed to compete with cable. This means 6 to 8 Mbps ADSL and eventually 52Mbps VDSL.

it doesn't make sense to break everything up into 53 byte cells. - jack colton

without the fixed packet size, atm would fail. the beauty of atm is the fixed packet size. i feel comfortable predicting we shall not see non-fixed sized atm packets. if you are suggesting atm packets will be of fixed larger byte cells, that is a possibility, but the packet size will be fixed.

Yes 53 octet cells and IP packets do not go together well. But when you scale up to a carrier backbone, virtual circuits do work very well. A carrier can resell his fiber over and over and over (you get the idea). So a stretch of fiber connecting 10GB switch ports, can carry over a terabit of VC's.

In an enterprise network, you can take the narrow view. But in a carrier network, you take the broad view.
