Glossary
EMC Electro-Magnetic Compatibility. The capability of equipment or
systems to be used in their intended environment within designed
efficiency levels without causing or receiving degradation due to
unintentional EMI (Electro Magnetic Interference). EMC generally
encompasses all of the electromagnetic disciplines.
ETSI European Telecommunications Standards Institute. A non-profit
organization producing voluntary telecommunications standards
used throughout Europe, some of which have been adopted by the
EC as the technical base for Directives or Regulations.
FCC Federal Communications Commission. A U.S. government agency
that supervises, licenses, and controls electronic and
electromagnetic transmission standards.
FDD Frequency Division Duplex. Full duplex operation by using a pair of
frequencies, one for transmission and one for reception.
FEC Forward Error Correction. A method of communicating data that
can corrects errors in transmission on the receiving end. Prior to
transmission, the data is put through a predetermined algorithm
that adds extra bits specifically for error correction to any character
or code block. If the transmission is received in error, the correction
bits are used to check and repair the data.
FFT Fast Fourier Transform. An algorithm for converting data from the
time domain to the frequency domain; often used in signal
processing.
FTP File Transfer Protocol. A protocol for exchanging files over the
Internet. FTP uses the Internet's TCP/IP protocols to enable data
transfer.
G.711 A 64 Kbps PCM voice-coding technique. Described in the ITU-T
standard in its G-series recommendations.
G.723.1 A compression technique that can be used for compressing speech
or audio signal components at a very low bit rate as part of the
H.324 family of standards. This codec has two bit rates associated
with it: 5.3 and 6.3 Kbps. The higher bit rate provides a somewhat
higher quality of sound. The lower bit rate provides system designers
with additional flexibility. Described in the ITU-T standard in its
G-series recommendations.
