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). Doug McCallum NBI, Inc. {allegra, ucbvax, ut-sally}!nbires!mccallum
