frame relay
See FR.
Frame Relay Forum
Based in Foster City, CA, this organization of frame-relay
equipment vendors, carriers, and users was formed in 1991 to
speed the development and deployment of frame relay prod-
ucts and interfaces with other broadband technologies such as
ATM.
Frame Relay Implementation Agree-
ment
See FRF.
frame relay policing
The prevention of frame relay traffic congestion through the
discard of packets that exceed specified traffic parameters.
Frame Relay/ATM Network Inter-
working Implementation Agreement
See FRF.5.
Frame Relay/ATM PVC Service
Interworking Implementation
Agreement
See FRF.8.
framing
The data-formatting conventions that allow a receiver to syn-
chronize with the transmitting end of a circuit. For example,
T-1 frames contain an 8-bit sample from each of the 24 chan-
nels on the interface (192 bits total) plus a framing bit (for a
total of 193 bits). Each framing bit marks the end of a timed
sample the input at the transmission end.
framing-bit
A bit used for frame synchronization purposes. A bit at a spe-
cific interval in a bit stream is used to determine the begin-
ning or end of a frame. Framing bits are non-information-car-
rying bits used to make possible the separation of characters
in a bit stream into lines, paragraphs, pages, channels, etc.
The framing in a digital signal is usually repetitive.
frequency shift keying
See FSK.
FRF.1.1
User-to-network (UNI) Implementation Agreement. The
interoperability standard adopted by the ATM Forum to
define connections between users or end stations and a local
switch.
FRF.2.1
Network-to-network (NNI) Implementation Agreement. The
interoperability standard adopted by the ATM Forum which
describes the transfer of C-Plane and U-Plane information
between two network nodes belonging to two different frame
relay networks.
FRF.5
Frame Relay/ATM Network Interworking Implementation
Agreement. The interoperability standard adopted by the
ATM Forum which defines a standard way to carry out frame
relay traffic across an ATM backbone. This specification is
dependent on the encapsulation of frames carried by the
frame relay network.
