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.
In a multimode optical fiber, a bound ray that travels in a helical path along the fiber and thus (a) is not parallel to the fiber axis, (b) does not lie in a meridional plane, and (c) does not intersect the fiber axis.
Industry:Telecommunications
In a network using dual counter-rotating yyring architecture, reconfiguration to circumvent a failed link or node. 2. In open systems architecture, the use of a network to connect two other networks, thus providing an increased interaction capability between the two connected networks. Note: Recurring application of wrapping usually results in a hierarchical structure.
Industry:Telecommunications
In a network, a group of users permitted to communicate with each other but not with users outside the group. Note: A user data terminal equipment (DTE) may belong to more than one closed user group.
Industry:Telecommunications
In a network, a line-unit-line termination (LULT) or a line-unit-network termination (LUNT. )
Industry:Telecommunications
In a network, a technique that allows data, including packet form, to be simultaneously transmitted to a selected set of destinations. Note: Some networks, such as Ethernet, support multicast by allowing a network interface to belong to one or more multicast groups. 2. To transmit identical data simultaneously to a selected set of destinations in a network, usually without obtaining acknowledgement of receipt of the transmission.
Industry:Telecommunications
In a network, an abstract representation of network resources that are managed. Note: A managed object may represent a physical entity, a network service, or an abstraction of a resource that exists independently of its use in management. 2. In telecommunications management, a resource within the telecommunications environment that may be managed through the use of operation, administration, maintenance, and provisioning application protocols.
Industry:Telecommunications
In a noise-measuring set, a noise weighting based on an amplitude-frequency characteristic that is flat over a frequency range that must be stated. Note 1: Flat noise power is expressed in dBrn (f1 - f2) or in dBm (f1 - f2. ) Note 2: "3-kHz flat weighting" and "15-kHz flat weighting" are based on amplitude-frequency characteristics that are flat between 30 Hz and the frequency indicated.
Industry:Telecommunications
In a packet, a field of the packet header that is used by the terminating endpoint to determine if the packets arrive in sequence.
Industry:Telecommunications
In a packet-switched network, a mode of transmission in which there is a complete information transfer transaction for each packet or group of packets, i.e., the information transfer phase is preceded by an access phase and followed by a disengagement phase. Note 1: During the information transfer phase of connection-oriented mode transmission, more than one packet may be transmitted. The header of each information packet contains a sequence number and an identifier field that associates the packet with the connection that was established during the access phase before the information transfer phase begins. Note 2: Connection-oriented mode transmission usually enables detection of lost, erroneous, duplicated, or out-of-sequence packets because a connection is established from end to end before transmission begins. Note 3: The ITU-T X. 25 protocols are widely used to implement connection-oriented mode transmission on packet-switched public data networks. The protocols are implemented at Layers 1, 2, and 3 of the Open Systems Interconnection--Reference Model. 2. The transfer of data between two or more peer entities which involves three distinct phases: connection establishment, data transfer, and connection release.
Industry:Telecommunications
In a packet-switched network, a switching capability in which each network switch extracts routing instructions from an incoming packet header to establish and maintain the appropriate switch connection for the duration of the packet, following which the connection is automatically released. Note: In concept, burst switching is similar to connectionless mode transmission, but it differs from the latter in that burst switching implies an intent to establish the switch connection in near real time so that only minimum buffering is required at the node switch.
