I hope that this discussion from the Cisco Learning Network might be helpful. Primary functions Produces the data and transfers them to a DCE, with essential control characters. Converts the signals to a format appropriate to the transmission medium and introduces it onto the network line. Coordination No coordination is required between DTE devices. DCE devices must be coordinated in order to communicate.

DTE Data terminating equipment is a terminal residing at physical layer or can be anything that could be able to generate to consume digital data like computers.

In other words, it is an assembly that operates either as a source of or as a destination for binary digital data. There is no direct mechanism for DTE to communicate, so communication occurs place through some intermediary devices.

Suppose your brain is a DTE device which can generate and consume ideas. Secondly, what is an example of a DCE? Data Communications Equipment, or DCE , is any device that supports data transmission over a serial telecommunications link. A data circuit-terminating equipment DCE is a device that sits between the data terminal equipment DTE and a data transmission circuit. It is also called data communication s equipment and data carrier equipment. Examples of DTE's are computers, printers, application servers, file servers, routers and bridges, dumb terminalsetc.

DTE do not generally communicate with each other. A serial cable is a cable used to transfer information between two devices using a serial communication protocol. The form of connectors depends on the particular serial port used. A cable wired for connecting two DTEs directly is known as a null modem cable.

The port used is V. Clock rate on routers. The clock rate serves to synchronize the receiver on the other side of the link. Each clock pulse signals the transmission of a bit.

Note that it is mainly used in lab setups. In the real world, network providers almost always deliver the clock signal. Null modem , also called crossover, is a term associated with serial RS cables. A standard serial cable , also called an AT cable , has the wires inside the cable running straight through.
