Cells in frames was a concept championed by Cornell University, among
others. What it was (maybe still is?) was a way of using Ethernet to
carry ATM cells, only for the purpose of testing ATM while using cheap
Ethernet hardware.

The idea of filling an Ethernet 1500-byte frame with ATM cells is only
valid for ATM testing if the Ethernet is very lightly loaded.
Otherwise, you can imagine, you gain nothing at all by stuffing an
Ethernet frame with ATM cells. You will simply get the kind of traffic
patterns you would expect from any Ethernet with heavily loaded frames.
