Designation:E 2185 01An American National StandardStandard Specification forTransferring Digital Voice Data Between Independent DigitalDictation Systems and Workstations1This standard is issued under the fixed designation E 2185;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers the format and content ofdigitally recorded voice data files and their identifying data.The object is to enable transfer between independent digitaldictation systems and workstations,regardless of manufacturerand protocols for ensuring reliability.This specification doesnot cover the transmission of voice data files and theiridentifying data within digital dictation systems and worksta-tions or their transcription into text files.1.2 This specification may be applied to either the transmis-sion of data over medium-to high-speed data communicationnetworks or to the transmission of data by recording on,andlater playing back from,magnetic or optical digital storagemedia.It defines the blocked stream of data,called a message,which is transmitted over a network connection or recorded ona storage medium.It does not define the hardware or softwarenetwork protocols or storage media formats needed for mes-sage transmission(for example,see ISO 8072-1986)or theformats used to store data internally by the sender or receiver.1.3 Since some standardization in storage media format andnetwork protocols would help to promote the exchange of databetween computer systems with diverse hardware and soft-ware,it is suggested that readily available universal media andformats be used for data exchange when possible.1.4 Any considerations regarding the security of the digitaldictation file or its components as defined herein are outside thescope of this specification.Such measures as encryption of files(either at rest or in transit),authentication of users or origina-tors,assignment and control of file access permissions,andbackup or recovery of files which may be necessary to meetinstitutional policies or governmental regulations are not ad-dressed in this specification.Guidance for security of dictatedhealth records can be found in Guide E 1902.2.Referenced Documents2.1 ASTM Standards:E 1762 Guide for Electronic Authentication of Health CareInformation2E 1902 Guide for Management for the Confidentiality andSecurity of Dictation,Transcription,and TranscribedHealth Records2E 1985 Guide for User Authentication and Authorization2E 2084 Specification for Authentication of Healthcare In-formation Using Digital Signatures22.2ANSI Standards:X3.172-1990 Dictionary of Information Processing3X3.4-1986 Coded Character SetsAmerican NationalStandard Code for Information Exchange(7 bit ASCII)42.3ISO Standard:ISO 8072-1986 Network Standards32.4Other Standards:Health Level Seven Standard(HL7),Version 2.3.15Resource Interchange File Format(RIFF)Standard6ITU G7.1173.Terminology3.1 Definitions:3.1.1 degradation of sound qualityin speech storage andreproduction,loss of intelligibility,reduced signal quality,andreduced ability to identify the speaker.The sound quality is amajor factor in transcription,where the user must listen tospeech for extended periods.The listener may have a reducedability to identify the speaker due to the degradation of soundquality.3.1.2 destination systemdigital dictation system that re-ceives dictation messages from another system.1This specification is under the jurisdiction of ASTM Committee E31 onHealthcare Informatics and is the direct responsibility of Subcommittee E31.22 onHealth Information Transcription and Documentation.Current edition approved Dec.10,2001.Published March 2002.2Annual Book of ASTM Standards,Vol 14.01.3Available from International Organization for Standards(ISO),1 rue deVarembe,Case Postale 56,CH-1211,Geneve 20,Switzerland.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th floor,New York NY 10036.5Available from Health Level Seven(HL7),3300 Washtenaw Ave.,Suite 227,Ann Arbor,MI 48104-4261.6A multimedia standard published as a joint design document by IBM andMicrosoft,available from Microsoft Corporation,One Microsoft Way,Redmond,WA 98052.7Available from International Telecommunications Union(ITU)(formerlyCCITT),Palais des Nations,CH-1211,Geneva 10,Switzerland.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.3.1.3 dictate workstation(or dictate station)device forinput of voice dictation and data that is captured and subse-quently stored.3.1.4 digital dictation recorderdevice designed specifi-cally to accept and store digital dictation from multiple discretesources.The recorder can usually be accessed by a variety ofmeans including,but not limited to,touch-tone tele
