Re: [MLUG - DISCUSSION] BNC/UTP hub

[Ryan Woodsmall <EMAIL:PROTECTED>]

Hmm, I don't know if this is on-topic but oh well.

There are in fact BNC 'hubs' out there, but they're really not hubs in the
same sense that UTP hubs are hubs.  That was poorly phrased, but you get
the idea.  The idea behind a BNC hub was generally to join two or more
network segments so you didn't get 'congestion' because of an overly large
segment.  BNC mostly worked, but could be *messy* if something went silly
with one machine.  The BNC hub also eliminated the problem of having one
large network with one point of failure; if one machine died, the part of
the network it was connected to died, but the rest of the network pretty
much continued as normal.

Granted, you probably could find such a beast, but in this day and age,
why?  I've saw a total of two of these BNC hubs (DEC and IBM,
respectively) in the four years of hell I spent as a PC/network 
technician.  They were both multi-thousand dollar affairs and were phased 
out when the network was upgraded to 10/100 UTP less than a year later... 
Pretty wasteful, pretty useless by today's standards.
