Systems Control

	Systems Control Systems control, in a communications system, is the control and implementation of a set of functions that: # prevent or eliminate Degradation (telecommunications), degradation of any part of the system, # initiate immediate response to demands that are placed on the system, # respond to changes in the system to meet long range requirements, and # may include various subfunctions, such as #* immediate Telecommunication circuit, circuit utilization actions, #* continuous control of circuit quality, #* continuous control of equipment performance, #* development of procedures for immediate repair, Circuit restoration, restoration, or replacement of facilities and equipment, #* continuous liaison with system users and with representatives of other systems, and #* the provision of advice and assistance in system use.

picture info	Communications System A communications system or communication system is a collection of individual telecommunications networks, transmission systems, relay stations, tributary stations, and terminal equipment usually capable of interconnection and interoperation to form an integrated whole. The components of a communications system serve a common purpose, are technically compatible, use common procedures, respond to controls, and operate in union. Telecommunications is a method of communication (e.g., for sports broadcasting, mass media, journalism, etc.). Communication is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules. Types By media An optical communication system is any form of telecommunication that uses light as the transmission medium. Equipment consists of a transmitter, which encodes a ''message'' into an optical '' signal'', a '' communication channel'', which carries the signal to its dest ...

	Degradation (telecommunications) In telecommunication, degradation is the loss of quality of an electronic signal, which may be categorized as either "''graceful''" or "''catastrophic''", and has the following meanings: #The deterioration in quality, level, or standard of performance of a functional unit. #In communications, a condition in which one or more of the required performance parameters fall outside predetermined limits, resulting in a lower quality of service. There are several forms and causes of degradation in electric signals, both in the time domain and in the physical domain, including runt pulse, voltage spike, jitter, wander, swim, drift, glitch, ringing, crosstalk, antenna effect (not the same antenna effect as in IC manufacturing), and phase noise. Degradation usually refers to reduction in quality of an analog or digital signal. When a signal is being transmitted or received, it undergoes changes which are undesirable. These changes are called degradation. Degradation is usually caused by: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Telecommunication Circuit A telecommunication circuit is a path in a telecommunications network used to transmit information. Circuits have evolved over time from generally being built on physical connections between individual hardware cables, as in an analog phone switch, to virtual circuits established over packet switching networks. Definitions A telecommunication circuit may be defined as follows: * The complete path between two terminals over which one-way or two-way communications may be provided. * An electronic path between two or more points, capable of providing a single or multiple communication channels. * An electronic closed-loop path among two or more points used for signal transfer. In operational terms, a telecommunication circuit may be capable of transmitting information in only one direction (''simplex'' circuit), or it may be bi-directional (''duplex'' circuit). Bi-directional circuits may support half- duplex operation, when only one end of the channel transmits at any one tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Circuit Restoration In telecommunication, circuit restoration is the process by which a communications circuit is established between two users after disruption or loss of the original circuit. The loss may be widespread due to a natural disaster like an ice storm or hurricane, or local by being cut underground in construction or damaged in a thunderstorm or car accident. Circuit restoration is usually performed in accordance with planned procedures and priorities. Restoration may be effected automatically, such as by switching to a hot standby, or manually, such as by manual patch Patch or Patches may refer to: Arts, entertainment and media * Patch Johnson, a fictional character from ''Days of Our Lives'' * Patch (''My Little Pony''), a toy * "Patches" (Dickey Lee song), 1962 * "Patches" (Chairmen of the Board song) ...ing.

picture info	Telecommunications Systems Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded ...
