Can someone tell me how they really work?  Or better yet, point me in a direction where I can read about them?  I am having problems explaining that if two machines are powered off in an fddi ring, they will not isolate the machine in the middle.  Senerio..



Machines on the ring (in order)


x y z a b


x and z are powered off for maintinence.  Can y talk to a or b?  I think that it can, since this is the reason for the OBS's.  The person that I am trying to explain this to is not convinced.  I think I need to tell him how the OBS works, to convince him.   


Any comments/suggestions are welcome, as always.


Tom.
