From a spec standpoint, acoustic modems were building over wires spec'd for bidirectional voice transmissions, i.e. symmetrical.

I'm curious about the nuances, but it seems like the last mile download/upload imbalance was created by the originating signal mode?

Download = First mile internet to ISP could be upgraded to digital, and thus grab some extra throughout by avoiding analog noise handling

Upload = First mile user to ISP was inherently analog over phone lines, and so sacrificed throughput for line noise tolerance
