C
CFM
Cubic feet per minute—A measurement of how
much air is moved through a fan.
CSA
Canadian Standards Association—Organization
which operates a listing service for electrical and elec-
tronic materials and equipment. It is the body that
establishes telephone equipment (and other) stan-
dards for use in Canada.
CT
Computer Telephony—is the adding of computer
intelligence to the making, receiving, and managing
of telephone calls.
D
Dual Redundant
An environment containing two power supplies,
with fault tolerance such that one power supply may
fail and the system will continue to operate.
E
EIA
Electronics Industry Association—Trade organiza-
tion of manufacturers which sets standards for use of
its member companies.
EMC
Electromagnetic Compatibility—Is the ability of
equipment or systems to be used in their intended
environment within designed efficiency levels with-
out causing or receiving degradation due to uninten-
tional EMI.
EMI
Electromagnetic Interference—any electromagnetic
interference, periodic or random, narrow or broad-
band, which may have a disturbing influence on
devices exposed to it.
EN
European Norms—Prefix assigned to documents
adopted by the CE designating required standards
(for example, EN 60950 is the safety specification
(equivalent to UL 1950)).
ESD
Electrostatic Discharge—Discharge of a static charge
on a surface or body through a conductive path to
ground. Can be damaging to integrated circuits.
H
Hot-Swap
The capability of removing and replacing compo-
nents without turning off the system. Hot-swap
capability is increasingly important in systems used
for applications such as telecommunications, which
require that the system be operational at some level
continuously.
HP
Horizontal Positioning—A unit of measurement
used for the width of cPCI cards/modules. 1 HP =
0.2” wide
I
IEC
International Electrotechnical Committee
IEEE
Institute of Electrical and Electronics Engineers
K
Keying
A mechanical means of polarizing connectors in
order to prevent similar connectors from being
mated. This is necessary when 2 or more similar con-
nectors must be connected to a backplane which
requires that the board being connected is unique for
a particular slot.
