Telecommunications_terms Telecommunications_terms Adaptive communications can mean any communications system, or portion thereof, that automatically uses feedback information obtained from the system itself or from the signals carried by the system to modify dynamically one or more of the system operational parameters to improve system performance or to resist degradation. ...more on Wikipedia about "Adaptive communications"
In telecommunication, the term anisochronous refers to a periodic signal, pertaining to transmission in which the time interval separating any two corresponding transitions is not necessarily related to the time interval separating any other two transitions. It can also pertain to a data transmission in which there is always a whole number of unit intervals between any two significant instants in the same block or character, but not between significant instants in different blocks or characters. Isochronous and anisochronous are characteristics, while synchronous and asynchronous are relationships. ...more on Wikipedia about "Anisochronous"
In telecommunication, an arithmetic shift is a shift, applied to the representation of a number in a fixed radix numeration system and in a fixed-point representation system, and in which only the characters representing the fixed-point part of the number are moved. An arithmetic shift is usually equivalent to multiplying the number by a positive or a negative integral power of the radix, except for the effect of any rounding; compare the logical shift with the arithmetic shift, especially in the case of floating-point representation. ...more on Wikipedia about "Arithmetic shift"
In telecommunication, an articulation score (AS) is a subjective measure of the intelligibility of a voice system in terms of the percentage of words correctly understood over a channel perturbed by interference. ...more on Wikipedia about "Articulation score"
Asynchronous communication is sending data without synchronization to an external clock. ...more on Wikipedia about "Asynchronous communication"

In telecommunication, a bipolar signal is a signal that may assume either of two polarities, neither of which is zero. ...more on Wikipedia about "Bipolar signal"
In telecommunication, the term commonality has the following meanings: ...more on Wikipedia about "Commonality"
In telecommunication a data link is the means of connecting one location to another for the purpose of transmitting and receiving data. It can also be an assembly, consisting of parts of two data terminal equipments (DTEs) and the interconnecting data circuit, that is controlled by a link protocol enabling data to be transferred from a data source to a data sink. ...more on Wikipedia about "Data link"
In telephony, a distribution frame is a closet or area set aside which contains equipment which multiplexes users' transmission mediums over a higher-capacity medium. A main distribution frame multiplexes many DSL lines over a larger cable such as fibre, for example. ...more on Wikipedia about "Distribution frame"
In telecommunication, a disturbance voltage is an unwanted voltage induced in a system by natural or man-made sources. ...more on Wikipedia about "Disturbance voltage"
In telecommunications, a hybrid balance is an expression of the degree of electrical symmetry between two impedances connected to two conjugate sides of a hybrid set or resistance hybrid. ...more on Wikipedia about "Hybrid balance"
In telecommunication, a longitudinal voltage is a voltage induced or appearing along the length of a transmission medium. ...more on Wikipedia about "Longitudinal voltage"
In telecommunication, a main distribution frame (MDF) is a distribution frame on one part of which the external trunk cables entering a facility terminate, and on another part of which the internal user subscriber lines and trunk cabling to any intermediate distribution frames terminate. ...more on Wikipedia about "Main distribution frame"
A Media Gateway acts as a translation unit between disparate telecommunications networks such as PSTN; Next Generation Networks; 2G, 2.5G and 3G radio access networks or PBX. Media Gateways enable multimedia communications across Next Generation Networks over multiple transport protocols such as ATM and IP. ...more on Wikipedia about "Media gateway"
Mediation function: In telecommunications network management, a function that routes or acts on information passing between network elements and network operations. ...more on Wikipedia about "Mediation function"
In telecommunication, a mesochronous network is a network in where the clocks run with the same frequency but unknown phases. Compare synchronous network. ...more on Wikipedia about "Mesochronous network"
In telecommunication, multipath is the propagation phenomenon that results in radio signals' reaching the receiving antenna by two or more paths. Causes of multipath include atmospheric ducting, ionospheric reflection and refraction, and reflection from terrestrial objects, such as mountains and buildings. ...more on Wikipedia about "Multipath"
A narrowcast is the transmission of data to a specific list of recipients. Cable television is an example of narrowcasting since the cable TV signals are sent only to homes that have subscribed to the cable service. In contrast, terrestrial TV uses a broadcast model in which the signals are transmitted everywhere and anyone with an antenna can receive them. ...more on Wikipedia about "Narrowcast"
In information technology, the Myth of the Nines refers to the idea that standard measurements of availability can be misleading. Availability is sometimes described in units of nines, as in "five nines", or 99.999%. Having a computer system's availability of 99.999% means the system is highly available, delivering its service to the user 99.999% of the time it is needed. ...more on Wikipedia about "The Myth of the Nines"
