FC
Feedback Control: Feedback controls are defined as the set of actions taken by the
network and by the end-systems to regulate the traffic submitted on ATM
connections according to the state of network elements.
FCC
Federal Communications Commission: The federal organization in Washington
D.C. set up by the Communications Act of 1934. It has the authority to regulate all
interstate (but not intrastate) communications originating in the United States. The
FCC is the U.S. federal regulatory agency responsible for the regulation of

FCS
Frame Check Sequence: Any mathematical formula which derives a numeric value
based on the bit pattern of a transmitted block of information and uses that value at
the receiving end to determine the existence of any transmission errors.
FDDI
Fiber Distributed Data Interface: A 100 Mbps Local Area Network standard that
was developed by ANSI that is designed to work on fiber-optic cables, using
techniques similar to token-ring.
FDDI-PMD
FDDI Physical Medium Dependant: This sublayer defines the parameters at the
lowest level, such as speed of bits on the media.The half of BISDN Layer 1.
FEBE
Far End Block Error: A maintenance signal transmitted in the PHY overhead that
a bit error(s) has been detected at the PHY layer at the far end of the link. This is
used to monitor bit error performance of the link.
FEC
Forward Error Correction: A technique for detection and correction of errors in a
digital data stream.
