If the Telebit modems are able to divide the bandwidth into many
channels, all at different frequencies, why can't they allocate some of
the channels for one direction and some for another?

If this were possible then it could dynamically adjust the bandwidth for
traffic in each direction.  The typical connection, both UUCP and
interactive, uses a lot of bandwidth in one direction, and relatively
little in the other.  Less than 50 baud can handle typing and less than
1200 could handle the ACKs on a 9600 baud UUCP connection.

Any body know the technical reason this can't be done?
