There is incoming data on the BNC port. There is incoming data on the AUI port. There is data collision on the network. Note that occasional collisions are normal. The BNC port is being partitioned because of excessive collisions, or when the BNC port is not connected. The AUI port is being partitioned because of excessive collisions. The link between this port and the other connecting port is good. There is incoming data on the port. The port is being partitioned because of excessive collisions. 2-2 Physical Description
