E
European transmission service at the rate of 2.048 Mbps.
E1
Transmission service at a rate of 34.368 Mbps.
E3
A frame relay feature to signal the onset of network congestion to external devices. Sets FECN and
ECN (Explicit
Congestion BECN bits in frame relay header to indicate forward and backward congestion.
Notification)
The Service Expansion Shelf is the controller on which the BPX's PNNI implementation runs. It is
SES
SPARC-based.
F
Same as interleaved EIA. Seven data circuit control leads in each direction are transmitted in
Fast EIA
alternating bytes with data. For fast control lead response to data being turned on and off but with a
sacrifice in packet line bandwidth
An AAL5 frame based traffic control that provides the possibility of discarding the whole frame, not
FBTC (Frame Based
Traffic Control) just one compliant cell. This avoids wasting bandwidth by continuing to send the cells in a frame once
a cell has been found to be non-compliant.
A feeder is a small switch that acts as an extension shelf, typically with lower-bandwidth interfaces,
Feeder
for a larger switch. The larger switch is referred to as the Routing node with the feeder(s) it supports.
Collectively, the feeder(s) and routing node form a type of supernode.
An enhancement option to GCRA that allows an entire frame to be discarded if any of its cells are
FGCRA (Frame
Based Generic Cell non-compliant, rather than transmitting a partial frame over the network.
Rate Algorithm)
A non-structured network, a network in which there are no junction nodes or domains.
flat network
An adjacent network that is owned and managed by a different party than the one that owns the local
foreign network
network.
A proprietary optional feature that uses feedback techniques to dynamically allocate extra bandwidth
ForeSight
to frame relay and ATM connections when the network bandwidth is available and not used by other
connections. (See also VSVD.)
A software feature allowing point-to-point frame relay type connection for various data applications
frame forwarding
that do not conform to the Frame Relay Interface Specification.
A tag for a frame relay circuit which indicates the class of service to be provided for this connection.
frame relay
connection class Parameters associated with a connection class include minimum information rate guaranteed, peak
information rate expected, maximum network delay, and so on.
The backcard for an FRM (IGX switch) card. The FRI provides V.35, X.21, T1, or E1 interfaces.
FRI (Frame Relay
Interface Card)
An IGX frame relay front card that supports 1-4 data ports, and in single-port mode, operates up to
FRM (Frame Relay
Module) 2.048 Mbps. The card is used in conjunction with FRI-V.35, X.21, T1, or E1 backcards.
