	Are you telling me that if I have a single piece of coax between 2
machines that I'll only use 20-25% of it?  Why?

	To be totally honest, there are 6 ethernet items on the segment
PERIOD.

	1) AIX 320H (Main box)
	2) Sun 3/50 4.1.1. (2nd DNS server - ONLY)
	3) PC w/SMC Ultra (Which only has the drivers loaded, nothing else)
	4) Terminal server (With no modems in it!)
	5) NCR X-Terminal (off 99.1% of the time)
	6) Fibre transceiver -> FO cable -> FO transceiver - > router to net

	Then what your saying is I need more equipment to be more active to
totally use my 10M effectively, and the same with the 56K?
