The advantage of the ethernet on broadband is that it works with
existing ethernet controllers and drop cables.  That means it should
work with non-DEC equipment and no new hardware has to be added to
use it if the system already has ethernet support.

Disadvantages are cost and the number of channels it takes on the
broadband system (equivalent to 3 CATV  channels).
