NOW, to end the Synoptics Lattisnet confusion once and for all:

With the introduction of the 3000 series concentrators, Synoptics
combined all of their available technologies on one bus.  Lattisnet
is a "catch all" phrase for all of these products.  They have
some modules that do proprietary twisted pair ethernet, and some that
so 10BaseT ethernet.  They have other products doing ethernet over
fiber and shielded twisted pair.  Caveat Emptor!  The marketing yoyos at 
Synoptics should really take more care to dfferentiate their products.

NEVERTHELESS!  The wary customer can simply look at THE LAST DIGIT of 
the model number of any module to know what it does.

HOW TO TELL WHAT YOUR SYSTEM 3000 module does.

If it ends in 7 or 8, that means it is 10 BaseT compatible:
>>> 3308 host module, 3307 host module, 408 module, 508 transciever.

If it ends in 5, it is the pre-standard propritetary twisted pair ethernet:
>>> 3305 host module, 505 tansceiver.

If it ends in 4 means it is an FOIRL (fiber optic inter repeater link) cabling:
>>> 3304 fiber module.

If it ends in 2 it is Ethernet over IBM type II cabling:
(also used for their Token Ring related products)
>>> 3302 shielded twisted pair host module, 502 transceiver.

If it ends in 3, that  means it is a non-station related module:
(also used to indicate modules with the 10Base5 AUI connection)
>>>  3313 network management, 3333 retiming, 3323 bridge, 3383 router, etc. 

If it ends in 1, that means it is a power supply 8-).

There will probably be a new designator for the FDDI modules when they
are released.  I think the prototypes at interop ended in a "9".

And you can mix and match all card types in the chassis.

Does THAT clear things up any?
