397.1works for meCGOS01::DMARLOWEdsk dsk dsk (tsk tsk tsk)Wed Sep 22 1993 14:155
    As long as the 10B2 is <= 55 meters and the 10BT is <= 100 meters,
    everything is ok.  You have 4 segments of which 1 is coax and 4
    repeaters between nodes on Hub #2 and Hub #3 (worst case path).

397.2Cross-cable between two 90TsHGOVC::GUPTATue Sep 28 1993 03:2910
    Ref .0:
    
    This config now works. We were trying with a wrong cable.
    
    The UTP cable linking HUB #1 and #3 needs to be cross.
    
    Thanks for the help.
