1. A distribution point in a network. 2. A device that accepts a signal from one point and redistributes it to one or more points.
Industry:Telecommunications
1. A digital signal rate of 44. 736 Mb/s, corresponding to the North American T3 designator. 2. A digital signaling rate of 32. 064 Mb/s, corresponding to the Japanese T3 designator.
Industry:Telecommunications
1. A digital signal rate of 274. 176 Mb/s, corresponding to the North American T4 designator. 2. A digital signaling rate of 97. 728 Mb/s, corresponding to the Japanese T4 designator.

1. A device that has as its critical component a metal wire or strip that will melt when heated by a prescribed (design) amperage, creating an open in the circuit of which it is a part, thereby protecting the circuit from an overcurrent condition. Note: Fuses are often characterized as "fast-blow" or "slow-blow," according to the time required for them to respond to an overcurrent condition. Fast-blow fuses open nearly instantaneously when exposed to an overcurrent condition. Slow-blow fuses can tolerate a transient overcurrent condition, but will open if the overcurrent condition is sustained. 2. In optical fiber technology, to join the endfaces of a pair of optical fibers by melting, i.e., welding, the endfaces together.

1. A defined geographic area identified by a unique three-digit code used in the North American Number Plan Area. Note 1: Defined geographic area could mean the entire area encompassed by the North American Numbering Plan Area (for 800, 888, 877 codes, etc. ) Note 2: By virtue of the overlay concept deployed in some states, there may be two (or more) NPAs assigned to the same defined geographic area. 2. Numbering Plan Area, also called area code. An NPA is the 3-digit code that occupies the A, B, and C positions in the 10-digit NANP format that applies throughout the NANP Area. NPAs are of the form NXX, where N represents the digits 2-9 and X represents any digit 0-9. In the NANP, NPAs are classified as either geographic or non-geographic. A) Geographic NPAs are NPAs which correspond to discrete geographic areas within the NANP Area. B) Non-geographic NPAs are NPAs that do not correspond to discrete geographic areas, but which are instead assigned for services with attributes, functionalities, or requirements that transcend specific geographic boundaries. The common examples are NPAs in the N00 format, e.g., 800. ~
Industry:Telecommunications
1. A dedicated device designed for the purpose of monitoring network traffic in order to recognize and decode certain packets of interest. 2. A software package that enables a general-purpose computer to recognize and decode certain packets of interest. Note: The packet sniffer is normally used by system administrators for network management and diagnostics, but is occasionally used by hackers for illicit purposes such as stealing a user's password or credit-card number. 3. In INFOSEC, synonym yysniffer.
Industry:Telecommunications
1. A database that is not entirely stored at a single physical location, but rather is dispersed over a network of interconnected computers. 2. A database that is under the control of a central database management system in which storage devices are not all attached to a common processor.
Industry:Telecommunications
1. A data link from a satellite or other spacecraft to a terrestrial terminal. 2. A data link from an airborne platform to a ground-based terminal.
Industry:Telecommunications
1. A data field in which is recorded (typically with a resolution of 1 millisecond) the cumulative variable queuing delay experienced by a packet in traversing the network. 2. With respect to a recorded network event, a data field in which is recorded the time (time of day or other instant of elapsed time) at which the event took place.
Industry:Telecommunications
1. A covert channel involving the direct or indirect writing to a storage location by one process and the direct or indirect reading of the storage location by another process. Covert storage channels typically involve a finite resource (e.g., sectors on a disk) that is shared by two subjects at different security levels. 2.
