	Right.  But all that is saying is that you don't run 10base2 to
interconnect multiple 10base5 segments.  You can certainly use 10base2 to
interconnect multiple 10base2 segments.  You only limits are the total
number of repeaters you can have "in series".

	This is allowed: ( imagine repeaters drawn in at each junction :-) )

	Why you would do this depends on your installation and the physical
topology of the network you are laying out.
