23、 permitted without license from IHS-,-,-TIA-602-AiiForeword(This Foreword is not part of this Standard)This Standard was formulated under the cognizance of TIA Subcommittee TR-30.2 on DataTransmission Interfaces and Protocols.This Standard is a revision of TIA/EIA-602, Data Transmission Systems and
24、Equipment -Serial Asynchronous Automatic Dialing and Control. ITU-T Recommendation V.250(formerly V.25bis) was approved by the ITU-T. The approval of V.250 was strongly backedby U.S. participants of Study Group 16. The TIA TR-30.2 members have determined thatITU-T Recommendation V.250 contains all o
25、f the requirements which were contained in thefirst edition of TIA/EIA-602. Recommendation V.250 goes on with additional commandswhich were not included in TIA/EIA-602. TIA/EIA-602-A therefore, is written to essentiallypoint to the ITU-T Recommendation V.250, listing those commands and options which
26、 arecontained in V.250 and apply to TIA/EIA-602-A.Copyright Telecommunications Industry Association Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-TIA-602-A11 SCOPEThis Standard is applicable to the interconnection of data ter
27、minal equipment (DTE) anddata circuit-terminating equipment (DCE) employing serial binary data operation via the ITU-T Recommendation V.24, 100-series interchange circuits. This Standard, through referenceto ITU-T Recommendation V.250, provides four elements:- codifies existing practice in common as
28、ynchronous DCE that use the AT commandset. It identifies the protocol elements procedures, and behaviors that were found to beheld in common among a large portion of DCE manufacturers;- defines a format for extension of the AT command set in an orderly fashion. Itreserves the “+“ command prefix to b
29、e used by other standardized extensions;- provides a set of standardized extensions, based on the extended “+“ commandformat.2 NORMATIVE REFERENCESThe following standards which, through reference in this text, constitute provisions of thisStandard. At the time of publication, the editions indicated
30、were valid. All standards aresubject to revision, and parties to agreements based on the Standard are encouraged toinvestigate the possibility of applying the most recent editions of the standards indicatedbelow. ANSI and TIA maintain registers of currently valid national standards published bythem.
