A crossover cable connects two devices of the same type, for example DTE-DTE or DCE-DCE, usually connected asymmetrically (DTE-DCE), by a modified cable called a crosslink. Such distinction of devices was introduced by IBM.
The crossing wires in a cable or in a connector adaptor allows:
connecting two devices directly, output of one to input of the other,
letting two terminal (DTE) devices communicate without an interconnecting hub knot, i.e. PCs,
linking two or more hubs, switches or routers (DCE) together, possibly to work as one wider device.
