Abstract

Enhanced collision detection in an Ethernet network, particularly useful for passive nodes using receive mode collision detection. When a transmitting node detects a collision, for example, using transmit mode collision detection, it activates a current sink at the node further reducing the DC potential on the line. This reduced DC potential assists in overcoming the low frequency impedance which may exist between the transmitting node and a remotely located passive node.
