Well, one other possibility is that the design of the V32terbo
protocol is not robust enough to allow for reliable coexistence
with V32bis, particularly as an addon later after V32bis has
become very widely used with hordes of modems implementing it.

In other words a rather crude kludge with some inevitable compromises
in the design of the protocol itself, which mean its got real problems.

RB> (Who invented that, Rockwell?)

Nope, AT&T from memory, but certainly not Rockwell,
as far as I know Rockwell never bothered with it at all.

Corse they did their own relatively crude kludge, VFC, instead.

Both were in fact just attempts to do something more than V32bis while
waiting for the V34 which was taking a long time to be formalised.

Oh sure, no argument there.

Rockwell never bothered with V32terbo.
