3288.0. "OBR (relay) for alarming" by MEO78A::BARNHOORN (Barney to his friends) Thu Feb 15 1996 22:14

    
    The Australian Telco here are going to offer FDDI services and are
    looking at using DECconcentrator 900MX.
    
    They have questions on alarm notification, they what a physical alarm
    to go off in the exchange/central office where the equipment will be
    located. They have asked about using the OBR port for device alarming.
    
    The OBR port of the concentrator will not go to a OBR but an alarming
    unit.  If the concentrator fails/losses power is what happens on the
    OBR port? What pins change state?
    
    Do we need to provide any signals at first on the OBR port?
    
    
    thanks for any information

You can read about the OBR connector wiring in UPSAR::FDDI Note 1940.*. 
KP7 will add...

I would not recommend using the OBR port for anything but an OBR device.
Unless, of course, you can answer with authority: "How is the OBR port
supposed to work?" and "Does the OBR for this concentrator really do that?".
