2399.0. "LB150 to DEFAR link?" by VAXRIO::ROLF (Vaporware Design Specialist) Tue Jun 20 1995 10:45

    (cross-posted in the Ethernet notefile)
    
    The field is trying to make a Remote LANbridge150 talk to a DEFAR-AA, via
    only a few meters of fiber (yes, we tried attenuators), yet they
    flatly refuse to cummunicate with eachother. Their behaviour is as if
    the fiber were nonexistant. 
    
    Each box passes self-test, has been swapped out, and the fiber link has 
    been tested with turn-around at its other extreme.
    
    What are we overlooking?
    
    Rolf, MCS DEC Brasil

	Check out the Lanbridge150 documentation - it says this can only connect to another 150 or to a DEREP repeater. I believe these products use a DEC proprietary fibre standard as opposed to the foirl and 10basefl standards implemented in more modern devices such as the DEFAR. John.
