Definition of "DCE" |
Data communications equipment; interchangeable with DTE / An abbreviation for data circuit-terminating equipment. In a data station, the equipment that performs functions, such as signal conversion and coding, at the network end of the line between the data terminal equipment (DTE) and the line, and that may be a separate or an integral part of the DTE or of intermediate equipment. The interfacing equipment that may be required to couple the data terminal equipment (DTE) into a transmission circuit or channel and from a transmission circuit or channel into the DTE. / Data communications equipment; interchangeable with DTE, defense coordinating element / Data Communications Equipment can be classified as equipment that transmits or receives analogue or digital signals through a network. DCE works at the physical layer of the OSI model taking data generated by Data Terminal Equipment (DTE) and converting it into a signal that can then be transmitted over a communications link. A common DCE example is a modem which works as a translator of digital and analogue signals. / Data communications equipment refers to computer hardware devices used to establish, maintain and terminate communication network sessions between a data source and its destination. DCE is connected to the data terminal equipment and data transmission circuit to convert transmission signals. / A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than mechanical clocks. / See data communications equipment or distributed computing environment. |
