FCS (Frame Check Sequence)

An algorithmically derived representation of a frame. (Typically 16 bits.) The

FCS provides error-checking capability. It is computed and appended at the time

of transmission and regenerated and compared upon reception.

Flash EPROM

EPROM that can be erased and reprogrammed while installed in a circuit.

Forward Explicit Notification Bit (FECN)

In Frame Relay, the FECN bit notifies the sending node (or source end) that there

is congestion in the direction of the data flow.

Frame

A frame is a unit of information transferred on a network which contains control

and data information.

Frame Check Sequence (FCS)

An error checking character that is appended to a bit-oriented protocol by the

transmitter.

Frame Relay

A streamlined public network technology well suited to burst traffic typical of

LAN interconnection.

Fs (Signal Framing)

The framing bit (f) identifies frames 6 and 12 in which signaling states, A and B

are transmitted when traffic on a network is channelized voice service.

Ft (Terminal Framing)

The framing bit (F bit) identifies the frame boundaries in a Frame Relay frame.

Full-duplex

A form of communication between two devices where packets flow in both

directions simultaneously. See also Half-duplex.

Gateway

A dedicated computer that is used to route frames from one dissimilar network to

another.
