A network control protocol in which (a) a carrier sensing scheme is used, (b) a data station that intends to transmit sends a jam signal, (c) after waiting a sufficient time for all stations to receive the jam signal, the data station transmits a frame, and (d) while transmitting, if the data station detects a jam signal from another station, it stops transmitting for a random time and then tries again.
Industry:Telecommunications
A network control scheme in which a node verifies the absence of other traffic before transmitting.
Industry:Telecommunications
A network designed for e-mail distribution through individual bulletin board systems rather than through Internet servers.
Industry:Telecommunications
A network designed to maintain phantom group balance when one side of the group is equipped with a carrier system. Note: Since it must balance the phantom group for only voice frequencies, the line filter balance configuration is usually simple compared with the filter that it balances.
Industry:Telecommunications
A network device that provides service to the network users by managing shared resources. Note 1: The term is often used in the context of a client-server architecture for a local area network (LAN. ) Note 2: Examples are a printer server and a file server.
Industry:Telecommunications
A network element that is part of a fiber-in-the-loop system interfacing the customer analog access cables and the fiber facilities.
Industry:Telecommunications
A network element that is used to arrange lower level digital signals among higher level digital bit streams. For example, DS0s among DS1s, DS1s among DS3s, or DS3s among OC3s, etc.
Industry:Telecommunications
A network established and operated by a telecommunications administration, or a recognized private operating agency, for the specific purpose of providing data transmission services for the public.
Industry:Telecommunications
A network having a loss that varies with frequency in a predetermined manner, and which network is used for improving or correcting transmission characteristics, or for characterizing noise measurements.
Industry:Telecommunications
A network in which clocks are controlled to run, ideally, at identical rates, or at the same mean rate with a fixed relative phase displacement, within a specified limited range. Note: Ideally, the clocks are synchronous, but they may be mesochronous in practice. By common usage, such mesochronous networks are frequently described as "synchronous. " 2. A network in which all clocks are normally (i.e., no-fault conditions) traceable to one or more primary reference sources, the difference in frequencies between them being negligible by definition.
