1、Designation: F1583 95 (Reapproved 2012)Standard Practice forCommunications ProceduresPhonetics1This standard is issued under the fixed designation F1583; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A

2、number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 Establishment of PhoneticsThis practice covers theestablishment of phonetics (including an alphabet, numerals,and punctuations), and th

3、e procedures for their use, in com-munications.1.2 Performance This practice is intended to facilitate theperformance of communications personnel and systems underadverse communications conditions. This objective is achievedby employing easily recognized and used symbols and proce-dures that are hig

4、hly resistant to errors. This system may beused with speech, print, or other media.1.3 Interoperability This practice is intended to facilitatethe interoperability of communications personnel and systemsamong different organizations, especially if they use differentinternal practices. This system is

5、 also recommended for usewithin any organization for improved internal communicationsand uniformity of operations.1.4 English as Common LanguageThis practice is in-tended for use with English. English has been designated bythe International Civil Aviation Organization (ICAO) andothers as a common in

6、teroperability language that is widelyused in search and rescue, emergency, and international opera-tions such as aviation, maritime, and military.2. Terminology2.1 The terminology used in this practice is derived fromreferences (1-10).2, 32.2 automatic repeat-request (ARQ)a system of errorcontrol f

7、or information transmission in which the receivingstation is arranged to detect a transmission error and automati-cally transmit a repeat-request signal to the transmittingstation. The transmitting station then retransmits the messageuntil it is either correctly received or the error persists beyond

8、a predetermined number of transmittals.2.3 error correcting codea code in which each symbolconforms to specific rules of construction so that departuresfrom this construction in the received signals can generally beautomatically detected and corrected. If the number of errors isnot greater than the

9、maximum correctable threshold of thecode, all errors are corrected.2.4 error correcting systemin information transmission, asystem employing either forward error correction or automaticrepeat-request techniques or both, such that most transmissionerrors are automatically removed from the data prior

10、todelivery to the user.2.5 forward error correction (FEC)a system of errorcontrol for information transmission wherein the receivingstation has the capability to detect and correct any character ormessage that contains fewer than a predetermined number ofsymbols in error.2.6 interoperabilitythe cond

11、ition achieved among com-munications stations or personnel when information can beexchanged directly and satisfactorily between them or theirusers or both. It is desirable that the exchanges are error free,rapid, and automatic.2.7 phoneticsa system of symbols and procedures that isused to control er

12、rors in communications, validate selectedparts of messages, and enhance the interoperability and perfor-mance of communications personnel and systems.2.8 phonetic alphabeta selected set of phonetic symbolsthat has a one-to-one correspondence to the set of individualletters in a language. Also, any o

13、f various systems of codewords for identifying letters in voice communications.2.9 phonetic punctuationa selected set of phonetic sym-bols that has a one-to-one correspondence to the set ofindividual punctuation in a language.1This practice is under the jurisdiction of ASTM Committee F32 on Search a

14、ndRescue and is the direct responsibility of Subcommittee F32.02 on Management andOperations.Current edition approved May 1, 2012. Published June 2012. Originallyapproved in 1995. Last previous edition approved in 2006 as F1583 95 (2006).DOI: 10.1520/F1583-95R12.2The boldface numbers in parentheses

15、refer to a list of references at the end ofthis practice.3This practice is based on an extensive survey of multiple organizations. Theircommunications documents were consulted to determine or verify compliance andinteroperability among their many known and accepted phonetic systems. Thesedocuments a

17、ique word or combination ofletters that is used as a substitute for, or an addition to, aspecific letter, numeral, or punctuation in a language. It has thecharacteristics of an error correcting code.3. Summary of Practice3.1 Interoperability and PerformanceA set of easily rec-ognized and used symbol

18、s and procedures are established.They are used to control the errors that may be encountered inmessages, to validate selected parts of messages, and toenhance the interoperability and performance of communica-tions personnel and systems. This phonetic system is intendedto be directly interoperable w

19、ith the majority of standardphonetic systems presently employed, both internationally andwithin the United States.3.2 Error Control Error control is accomplished by de-tection of the errors and either prompt correction (based on theavailable information) or a request for another copy (if theinformat

20、ion is inadequate for error correction).4. Significance and Use4.1 Communications Errors and DelaysCommunicationssystems, including their procedures and channels, are subject toerrors due to noise, interference, weak signals, mistakes, andother causes. They are also subject to delays due to theneces

21、sity to detect and correct these errors. There may also beerrors and delays due to the lack of trained and experiencedoperators.4.2 Error Control Phonetics enables the control of errorsthrough error detection, and usually prompt correction, forwords and characters in speech and printed text. It empl

22、oys anerror correcting system of symbols and procedures that arestandardized and easily recognized under adverse or high errorcommunications conditions.4.3 Symbol CharacteristicsThe phonetic alphabet is anerror detecting and correcting code composed of phoneticsymbols that are carefully selected to

23、have distinctive soundsor appearances (or other unique characteristics) that improvedetection under adverse conditions (such as severe noise orhigh errors) and enhance differentiation from each other.4.3.1 Phonetics are inherently language-dependent. ForEnglish text letters, there are 26 phonetic al

24、phabet symbols,that correspond to the 26 letters (from A to Z) that may be usedto compose the words in a message. Additional symbols areused for numerals and punctuations.4.3.2 Phonetic symbols (including an alphabet, numerals,and punctuation) must have unique characteristics as men-tioned above, an

25、d they should not be restricted to only onecommunications media.4.4 Procedures for Error Detection and Correction:4.4.1 Phonetic communications procedures are used tominimize or eliminate information errors and to facilitate thecorrect transmission of messages using trained operators.4.4.2 The phone

26、tic procedures are carefully structured toenable symbol differentiation and error detection based onsimple examination of the received data. Using forward errorcorrection (FEC), in most cases the symbols can be identified,and the errors can be corrected promptly with no additionalinformation.4.4.3 F

27、EC is based on the error detection system, which isusually the more robust of the two. Essentially, in certain poorconditions, it is possible to detect errors even though they maynot be correctable (at the moment).4.5 Procedures for RetransmissionIn most cases, prompterror detection and correction i

28、s achievable through FEC. Ifthis is not possible or acceptable, manual or automatic repeat-request (ARQ) is employed. The process of error detection canbe used to initiate the ARQ and therefore the retransmission ofthe information, such as an additional copy (or copies). Thecopy(ies) may be received

29、 error free or with correctable errors(especially when compared with previous copy(ies).4.6 Use of Non-standard SystemsThis phonetic system isnot intended to prohibit the use of non-standard brevity or errorcontrol systems that are used only internally within any singleorganization. It also does not

30、 preclude the use of additionalmethods for clarity.4.7 Use of Standard SystemsThis phonetic system isintended to be directly interoperable with the majority ofstandard phonetic systems presently employed, both interna-tionally and within the United States, as noted in references(1-9). These standard

31、 systems actually exhibit many variationsamong themselves. Some provide no procedures, and noneinclude all of the symbols presented herein. Of all these knowndocuments, this practice is the only one that presents anexplanation of the phonetic system in terms of modern com-munications technology. To

32、achieve interoperability and per-formance through bona fide standardization, system adminis-trators should consider this comprehensive practice forsuperseding, or revising, these other standard systems.5.
