A congestion-control technique in which a computer experiencing data traffic congestion sends a message back to the source of the messages or packets causing the congestion, requesting that the source stop transmitting.
Industry:Telecommunications
A connection established via a service order or via network management.
Industry:Telecommunications
A connectionless, broadband, packet-switched data service that provides LAN-like performance and features in metropolitan or wide areas. Note: Currently SMDS operates at 1. 544 Mb/s (megabits per second) or 44. 736 Mb/s. These are the T1 and T3 rates, respectively, over switched fiber optic networks.
Industry:Telecommunications
A connector that contains contacts for more than one type of service. Note: Examples of hybrid connectors are those that have contacts for both optical fibers and twisted pairs, electric power and twisted pairs, or shielded and unshielded twisted pairs.
Industry:Telecommunications
A constituent element of data that takes either of two values or states. Note: Binary element should not be confused with binary digit.
Industry:Telecommunications
A consumer audio-recording and playback medium/format that maintains a signal quality equal to that of the CD-ROM medium/format.
Industry:Telecommunications
A contiguous group of characters or bits that are corruption-protected by being processed by the authentication algorithm.
Industry:Telecommunications
A contiguous sequence of symbols, received over a data transmission channel, such that the first and last symbols are in error and there exists no contiguous subsequence of m correctly received symbols within the error burst. Note: The integer parameter m is referred to as the guard band of the error burst. The last symbol in a burst and the first symbol in the following burst are accordingly separated by m correct bits or more. The parameter m should be specified when describing an error burst.
Industry:Telecommunications
A continuous range or spectrum of frequencies that extends from one limiting frequency to another. Note 1: The frequency range for given equipment specifies the frequencies at which the equipment is operable. For example, filters pass or stop certain bands of frequencies. The frequency range for propagation indicates the frequencies at which electromagnetic wave propagation in certain modes or paths is possible over given distances. Frequency allocation, however, is made in terms of bands of frequencies. There is little, if any, conceptual difference between a range of frequencies and a band of frequencies. Note 2: "Frequency band" usually identifies a specific band of frequencies in the Tables of Frequency Allocations.
