ATIS is the leading technical planning and standards development organization committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry.
A multiplexed transmission system in which the rates of the carrier and its tributaries are not traceable to the same master clocking source. Note: In this type of system, extra signal elements are usually appended to the individual tributary signals for the purpose of interleaving them at a rate consistent with the carrier rate.
Industry:Telecommunications
A multiplexer that consists of multilayered films of material of different optical characteristics, is capable of multiplexing transmitted light by using electro-optic, electro-acoustic, or magneto-optic effects to obtain signal multiplexing, and may be used as a component in integrated optical circuits.
Industry:Telecommunications
A multiplexing function offered in connection with SONET that allows lower level signals to be added or dropped from a high-speed optical carrier channel in a wire center. The connection to the add/drop multiplexer is via a channel to a central office port at a specific digital speed (i.e., DS3, DS1, etc. )
Industry:Telecommunications
A multiplexing scheme in which timing is obtained from a clock that controls both the multiplexer and the channel source.
Industry:Telecommunications
A multiplier used to transform the real time of occurrence of an event or a problem into system time, such as that of a telecommunications system or a computer.
Industry:Telecommunications
A multiport device, by means of which two or more audiovisual terminals may intercommunicate in a conference call. Note: A "principal MCU" has been assigned a superior controlling function in a call where two or more MCUs in that call are termed "satellite MCUs". The physical realization of an MCU may be such that two or more independent conferences may be set up within the same unit; logically, however, there is no relationship between these conferences; the text of this definition refers to an MCU only as a logical entity pertinent to the particular call of concern.
Industry:Telecommunications
A mutually synchronized network in which all clocks in the network are of equal status and exert equal amounts of control on the others, the network operating clock pulse repetition rate being the mean of the natural (uncontrolled) clock pulse repetition rates of the population of clocks.
Industry:Telecommunications
A mutually synchronized network in which some clocks exert more control than others, the network operating frequency being a weighted mean of the natural frequencies of the population of clocks.
Industry:Telecommunications
A name or address of an Internet resource, stored in a software file at a user's site, e.g., in a desktop computer, for convenient future use. Note: An example of a bookmark is an entry in a bookmark file (or bookmark list) such as maintained within or by a Web browser for the convenience of the user in revisiting a previously visited Web site.
Industry:Telecommunications
A named component of a data element; usually the smallest component. 2. A subunit of descriptive information or value classified under a data element. For example the data element "military personnel grade" contains data items such as sergeant, captain, and colonel.
