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.
An error detection and/or correction code in which the encoded block consists of N symbols, containing K information symbols (K<N) and N-K redundant check symbols, such that most naturally occurring errors can be detected and/or corrected.
Industry:Telecommunications
An Error of commission or omission in an information system (IS) that may allow protection mechanisms to be bypassed.
Industry:Telecommunications
An error-detecting and error-correcting binary code, used in data transmission, that can (a) detect all single- and double-bit errors and (b) correct all single-bit errors. Note: A Hamming code satisfies the relation 2m n+1, where n is the total number of bits in the block, k is the number of information bits in the block, and m is the number of check bits in the block, where m = n - k.
Industry:Telecommunications
An error-detection scheme that (a) uses parity bits generated by polynomial encoding of digital signals, (b) appends those parity bits to the digital signal, and (c) uses decoding algorithms that detect errors in the received digital signal. Note: Error correction, if required, may be accomplished through the use of an automatic repeat-request (ARQ) system. 2. An error checking mechanism that checks data integrity by computing a polynomial algorithm based checksum.
Industry:Telecommunications
An essential part of many fiber-optic cable designs, consisting of a layer of woven yarn. Note: In the case of single-fiber loose-buffered or two-fiber "zip-cord" loose-buffered fiber-optic cables, the braid is situated between the buffer tube and jacket. In the case of cables having multiple buffer tubes, the braid is usually situated between the inner jacket and outer jacket. 2. Loosely, an unwoven parallel bundle of yarn situated around the tight buffer of a single-fiber or two-fiber "zip-cord" fiber-optic cable. Note 1: The braid serves to add tensile strength to the cable. The braid may also be anchored to an optical connector or splice organizer assembly to secure the end of the cable. Note 2: The braid is often of an aramid yarn.
Industry:Telecommunications
An event beginning with the occurrence of a bit error ratio (BER) of 10-2 or worse, continuously for each of three or more consecutive seconds, which can last up to 120 seconds. An SIE clears when 10 consecutive seconds pass in which none of them is an SES. Note: The 10-2 BER continuously over each second implies that all sub-intervals, where the second is divided into at least 10 equal subintervals, have a BER of 10-2 or worse.
Industry:Telecommunications
An event characterizing the completion of the initial alignment procedure on a signaling link following the removal of the previous causes of failure; in the absence of any other causes of its unavailability, the signaling link once again becomes available.
Industry:Telecommunications
An event that causes the unavailability of a signaling link, typically consisting in a "processor outage" condition at one end of that signaling link.
Industry:Telecommunications
An event that causes the unavailability of a signaling link, typically consisting of a failure in signaling terminal equipment or in the signaling data link.
Industry:Telecommunications
An examination of the procedures used in a data processing system to evaluate their effectiveness and correctness, and to recommend improvements.
