A packet switching technique that increases the throughput by eliminating overhead.
Note 1: Overhead reduction is accomplished by allocating flow control and error correction functions to either the user applications or the network nodes that interface with the user.
Note 2: Cell relay and frame relay are two implementations of fast packet switching.

An optional user facility in the virtual call service of CCITT X.25 protocol (now, ITU-T X.25 protocol) that allows the inclusion of user data in the call request/connected and clear indication packets.
Note: Fast select is an essential feature of the CCITT X.25 (1984) protocol.

Fiber Access Terminal

A client-centric computing model where software must be installed on each client in a network. This often requires that each client computer be upgraded to the same level.

1. An accidental condition that causes a functional unit to fail to perform its required function.
2. A defect that causes a reproducible or catastrophic malfunction.
Note: A malfunction is considered reproducible if it occurs consistently under the same circumstances.
3. In power systems, an unintentional short-circuit, or partial short-circuit, between energized conductors or between an energized conductor and ground.

Powering system that monitors for emulated human contact faults and controls power delivered to ensure fault energy is limited.

The National Electrical Code defines FMPS as a power distribution system consisting of a class 4 circuit where the system monitors for faults and controls power delivery to prevent a shock or fire hazard.

In network management, the set of functions that (a) detect, isolate, and correct malfunctions in a telecommunications network, (b) compensate for environmental changes, and (c) include maintaining and examining error logs, accepting and acting on error detection notifications, tracing and identifying faults, carrying out sequences of diagnostics tests, correcting faults, reporting error conditions, and localizing and tracing faults by examining… (Read More →)

In a facility power distribution system, the subsystem that provides a direct path from each power sink to the earth electrode subsystem.
Note: The fault protection subsystem is usually referred to as a "green wire. "

The extent to which a functional unit will continue to operate at a defined performance level even though one or more of its components are malfunctioning.
