DCE woul provide clocking with clock rate command

DTE is a device that acts as an information source or an information sink for the binary digital data. In contrast, DCE is a device used as an interface between a DTE. It also transmits or receives data in the form of digital or analog signal in a network.
DTE produces the data and traverses them, with the required control characters to a DCE. On the other hand, DCE converts the signals to a format appropriate to the transmission medium and introduces it onto the network line.
Coordination is mandatory in DCEs so as to communicate whereas it is not the case in DTE.
Two DTEs connect with each other by utilizing DCE network
