In military communications, a priority scheme (a) for assigning one of several precedence levels to specific calls or messages so that the system handles them in a predetermined order and time frame, (b) for gaining controlled access to network resources in which calls and messages can be preempted only by higher priority calls and messages, (c) that is recognized only within a predefined domain, and (d) in which the precedence level of a call outside the predefined domain is usually not recognized.
Industry:Telecommunications
In military communications systems, the processing of a message from (a) a given military network, such as a tape-relay network, a point-to-point telegraph network, a radio-telegraph network, or the DSN to (b) a commercial communications network. Note: Commercial refiling of a message will usually require a reformatting of the message, particularly the heading.
Industry:Telecommunications
In military communications systems, a message in which the entire address is encrypted with the message text.
Industry:Telecommunications
In microwave line-of-sight communications, the perpendicular distance from the radio-beam axis to obstructions such as trees, buildings, or terrain. Note: The required path clearance is usually expressed, for a particular k-factor, as some fraction of the first Fresnel zone radius.
Industry:Telecommunications
In message communications, the preservation of the exact number of bits that are in the original message. 2. In connection-oriented services, preservation of the number of bits per unit time. Note: Bit-count integrity is not the same as bit integrity, which requires that the delivered bits correspond exactly with the original bits.
Industry:Telecommunications
In magnetic or optical disk storage, sectoring that uses a physical mark on the disk, from which mark sector locations are referenced. Note: Hard sectoring may be done, for example, by punching an index hole in a floppy diskette. When the presence of the index hole is recognized by an optical reader, a reference signal is generated. All sector locations can be referenced from this signal.
Industry:Telecommunications
In magnetic or optical disk storage media, the division of tracks into a specified number of segments, for the purpose of organizing the data stored thereon.
Industry:Telecommunications
In logistics, an item forming a portion of an equipment that can be provisioned and replaced as an entity and which normally incorporates replaceable parts or groups of parts.
Industry:Telecommunications
In local area networks, transmission by a data station beyond the time interval allowed by the protocol.
Industry:Telecommunications
In Link-Layer protocols, such as high-level data link control (HDLC,) synchronous data link control (SDLC,) and advanced data communication control procedure (ADCCP,) an unnumbered command used to terminate the operational mode previously set.
