Glossary

CONUS — Continental United States. Acronym used to identify standards for circuits

in the continental United States.

CS — Clear to send from DCE circuit (RS-449/ V.36, and MIL-188-114).

CTS — Clear to send from DCE circuit (all supported interfaces except RS-449/ V.36,

MIL-188-114, and X.21). See CS and I.

DB-9 — Standard 9-pin RS-232 serial port or connector.

DB-25 — 25-pin RS-232/V.24 or EIA-530 serial port or connector.

DCE — Data Communications Equipment. Equipment that acts as an interface

between a Data Terminal Equipment (DTE) device (such as a modem) and a commu-

nications medium. See DTE.

Diphase encoding — See Manchester encoding.

DM — Data set ready from DCE circuit (RS-449/V.36, and MIL-188-114).

DSR — Data set ready from DCE circuit (all supported interfaces except RS-449, V.36,

and MIL-188-114). See DM.

DTE — Data Terminal Equipment. Equipment that serves as the data transmission

source, data transmission destination, or both, for the purpose of sending or receiving

data. Examples of DTEs include personal computers (PCs), data terminals, and periph-

eral devices such as printers. You can configure the instrument to emulate a DTE

device when testing most data communications interfaces. See DCE.

DTR — Data terminal ready to DCE circuit (all supported interfaces except RS-449/

V.36, and MIL-188-114). See TR.

EIA-530 — Recommendation EIA-530 describes a data communications interface that

uses balanced V.11 amplifiers for clock and data circuits, and V.10 amplifiers for

signaling circuits. It also describes the EIA-530A data communications interface that

uses V.10 amplifiers for all circuits.

G.821 — ITU-T recommendation addressing error performance of an international

digital connection operating at a bit rate below the primary rate and forming part of an

integrated services digital network.

GUI — Graphical User Interface. Layout of commands in a user-friendly environment.
