FPGA

Field Programmable Gate Array: A specialized microprocessor manufactured
without physical connections between its logic gates, but with potential
connections that can be firmed up in the field. (paraphrased from Newton)

FRS

Frame-Relay Service: A connection oriented service that is capable of carrying up
to 4096 bytes per frame.

FRTT

Fixed Round-Trip Time: This is the sum of the fixed and propagation delays from
the source to the furthest destination and back.

G.703

ITU-T Recommendation G.703, "Physical/Electrical Characteristics of
Hierarchical Digital Interfaces".

G.704

ITU-T Recommendation G.704, "Synchronous Frame Structures Used at Primary
and Secondary Hierarchy Levels".

G.804

ITU-T Recommendation G.804, "ATM Cell Mapping into Plesiochronous Digital
Hierarchy (PDH)".

GCAC

Generic Connection Admission Control: This is a process to determine if a link has
potentially enough resources to support a connection.

GCRA

Generic Cell Rate Algorithm: The GCRA is used to define conformance with
respect to the traffic contract of the connection. For each cell arrival the GCRA
determines whether the cell conforms to the traffic contract. The UPC function may
implement the GCRA, or one or more equivalent algorithms to enforce
conformance. The GCRA is defined with two parameters: the Increment (I) and the
Limit (L).
