Data Communication Equipment
<communications, hardware> (DCE) The devices and connections
of a communications network that connect the communication
circuit between the data source and destination (the {Data
Terminal Equipment} or DTE). A modem is the most common
kind of DCE.
Before data can be transmited over a modem, the DTR (Data
Terminal Ready) signal must be active. DTR tells the DCE that
the DTE is ready to transmit and receive data.
DCE and DTE are usually connected by an EIA-232 {serial
line}. It is necessary to distinguish these two types of
device because their connectors must be wired differently if a
"straight-through" cable (pin 1 to pin 1, pin 2 to pin 2 etc.)
is to be used. DCE should have a female connector and should
transmit on pin two and receive on pin three. It is a curious
fact that many modems are "DTE" according to the original
standard.

Data Communications Equipment
Data circuit-terminating equipment
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.

Data circuit-terminating equipment
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. Usually, the DTE device is the terminal (or computer), and the DCE is a modem.
In a data station, the DCE performs functions such as signal conversion, coding, and line clocking and may be a part of the DTE or intermediate equipment. Interfacing equipment may be required to couple the DTE into a transmission circuit or channel and from a transmission circuit or channel into the DTE.
