DTE is generally referred to as a "data terminal device" and DCE is generally referred to as a "data communication device." In other words, DTE devices are also "active communication devices", and DCE devices are also "passive communication devices." Two types of devices that use the RJ45 interface to connect for communication require a crossover connection.
