Well lots and lots of people understand ATM networking!

Probably more accurate to say that ATM uses fixed a fixed cell size.
This is a compromise between efficiency for data transfer, and
audio/video.
The fixed cell size makes it easy to build fast hardware based routing
switches - in an age where the state of the art for IP based routing was
software based switches. (I've no idea of the computational power of
Cisco switches of the time, but I'd guess they were something like
486es)
