Abstract
A system and method are disclosed for transmitting signals from a digital MAC interface to a bus and for transmitting signals from a bus to a digital MAC interface. A first bus data line is modulated by holding the first bus data line at a potential when the transmit data line is in a first state and allowing the first bus data line to float when the transmit data line is in a second state when data transmission from the digital MAC interface is enabled. A second bus data line is modulated by holding the second bus data line at a potential when the transmit data line is in the second state and by allowing the second bus data line to float when the transmit data line is in the first state. One of the bus data lines are connected to a receive data line on the digital MAC interface. The state of the first data line is compared to the state of the second data line the collision line is set to a fist preselected state when the state of the first data line and the state of the second data line are both a second preselected state.
