Data terminal equipment (DTE)​ is an end instrument that converts user information into signals or reconverts received signals. These can also be called tail circuits. A DTE device communicates with the data circuit-terminating equipment (DCE). Usually, the DTE device is the terminal (or a computer emulating a terminal), and the DCE is a modem. A DTE is the functional unit of a data station that serves as a data source or a data sink and provides for the data
communication control function to be performed in accordance with the link protocol.
