I don't have the 3Com manual handy but the Western Digital manual warns
that the option for 300 meter segments requires that the network consist
of a single segment and all the cards on that segment must be configured
with that option.

In other words this is for isolated networks between 180 and 300 meters
that want to avoid the cost of a repeater.
