    Carrier transitions just mean the link has flapped. See the exact description from Juniper

     

        Carrier transitions—Number of times the interface has gone from down
         to up. This number does not normally increment quickly,
        increasing only when the cable is unplugged, the far-end system is
        powered down and then up, or another problem occurs. If the number
        of carrier transitions increments quickly (perhaps once every 10 seconds),
        the cable, the far-end system, or the PIC or PIM is malfunctioning.

     

    You would need to do basic troubleshooting to find out why the link is flapping. Those steps would be different if it was a telco circuit or an P2P ethernet cable.
