What gives is that 3com is non-standard. As soon as you extend a segment 
beyond 185m it ceases to be 803.2

But Ethernet is robust enough that you can do all kinds of non-standard 
things to it and it'll still work. You can actually get away with it with 
most Ethernet products but only 3com claims to be specifically designed to 
do it in a reliable fashion.
