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.
