Abstract
A method and apparatus for detecting a collision between signal transmissions on a carrier medium, such as UTP wiring, are described. The method commences with the transmission of an access identifier from a transmitter of a network device. The transmitted access identifier has a predetermined duration and includes a pulse at a temporal location within the transmitted access identifier specific thereto. An access identifier is also received at a receiver of the network device. The received access identifier also has a predetermined duration, and includes a pulse at a temporal location therein. A determination is then made as to whether the temporal location of the pulse within the received access identifier corresponds to the temporal location of the pulse within the transmitted access identifier. If not, a collision is detected on the network.
