Whoa.  Be careful here.  Synoptics makes two products.  One is their older
LattisNet product that is *not* compatible with 10BaseT - it is a pre-standard
form of Ethernet over UTP (very similar to 10BaseT, but not compatible).
Their new products *are* 10BaseT compatible.  To make things confusing,
both products are available in the 3000 series product line.  The 3000 series
product line uses one of two concentrator chassis (a 3 slot and a twelve slot)
into which card modules are pluged.  You can buy either LattisNet or 10BaseT
modules for 3000 series concentrators.

The only product that I know of sold under Western Digital's name is a clone
of Synoptics' 2500 series line.  This line was only ever produced using
LattisNet technology, not 10BaseT.  I don't know if Western Digital has
since brought out a 10BaseT concentrator.  I know that Synoptics has *not*
ungraded the 2500 series to 10BaseT and probably never will.

I suspect that Synoptics will be phasing out LattisNet sometime soon for new
accounts.  Anyone know for sure?

BTW, 10BaseT is no longer draft...
