DCE: Data Circuit-terminating Equipment

DCE is an abbreviation of "Data Circuit-terminating Equipment". It is also known as data communications equipment and data carrier equipment, basically, a communication-based device, which works as a communication bridge between the data terminal equipment (DTE) and a data transmission circuit. It carries out a variety of tasks, which comprise conversion of signals, coding, line clocking, etc. A number of further interfacing electronic equipment possibly will also be essential to join up the data terminal equipment (DTE) into a communication channel or transmission circuit and in the form of starting point of transmission circuit or channel into the DTE.

A crossover cable is supposed to be used in a situation when two devices, that are either DTE or both DCE, required to be linked simultaneously to establish a connection devoid of a modem or a related audiovisual translator between them, such as an Ethernet crossover cable.


The data communications standards which uses DCE communication device in the establishment of connection with the data terminal equipment (DTE), comprise:

  • Federal Standard 1037C: It is a United States Federal Standard published by the General Services Administration.
  • MIL-STD-188: It is a sequence progression of U.S. military standards, which are associated with telecommunications.
  • RS-232: It is a standard, which is fundamentally established in case of the serial communication transmission of data to characterize the electrical features, signals timing, the significance of signals etc.
  • Some particular ITU-T based standards in the V series such as V.24 and V.35
  • Some particular ITU-T based standards in the X series such as X.21 and X.25
