D

Data Communications Equipment (DCE)

(Also called Data Circuit-terminating Equipment) The equipment that provides the

functions required to establish, maintain and terminate a data communications

connection. The DCE also provides any required signal conversion for communication

between the data terminal equipment (DTE) and the telephone line or data circuit.

Data metering

A selectable feature of the 8400B Plus Data Module that allows the device and its

associated terminal to operate at a higher speed than the remote system to which it is

connected.

Data mode

See on-line mode.

Data options

For asynchronous data communications, these parameters include data transfer speed

(expressed in bits/second or bps, and sometimes called bau d rate), pa rity, data word size

(or data bits), and stop bits. Generally, these parameters must be set to match at both

ends of the communication line. Except when the data metering option is enabled, the

8400B Plus Data Module attempts to adjust to match the speed of the remote device. If

the data module is unable to match the speed, the call is disconnected. Also called

communications parameters. See also asynchronous data communications and data

metering.

Data Terminal Equipment (DTE)

A device that sends and/or receives data over a communication line via a DCE.

Examples of DTE devices are a display terminal, a PC running appropriate data

communications software, or a printer or plotter.

DCE

See Data Communications Equipment.
