FCS (Frame Check Sequence)
An algorithmically derived representation of a frame. (Typically 16 bits.) The FCS provides
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
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
Gateway
A dedicated computer that is used to route frames from one dissimilar network to another.
