Annex G (Informative) Differencesfrom TIAIEIA-592 - 1993 94 (This foreword is not part of this Standard) FOREWORD This Standard was prepared by the Telecommunications lndustry Association Technical Subcommittee TR
38、-29.2, Facsimile Digital Interfaces. This Standard was prepared with significant help the from TIA Technical Subcommittee TR-30.4, DTE- DCE Protocols and TR-45.3.2.5, a working group of TR-45.3, Digital Cellular Technology. This Standard requires that a conforming device implement the services and p
39、rocedures defined in Section 9, previously published as ANSIITINEIA-605, Facsimile Systems and Equipment - Facsimile DCE-DTE Packet Protocol. There were no amendments to the Packet Protocol. A device that conforms to this Standard may commonly implement the services and procedures defined in: ITU-T
40、Recommendation V.25ter DATA COMMUNICATION OVER THE TELEPHONE NETWORK - Serial Asynchronous Automatic Dialing and Control and, ITU-T Recommendation T.31 TERMINALS FOR TELEMATIC SERVICES - Asynchronous Facsimile DCE Control, Service Class 1. ., Annex G describes the differences between TINEIA-592 and
41、this version. TINEIA-592-A reflects the content of the ITU-T Recommendation T.32 (8195) and its Amendment 1 (7196). The differences between TIAIEIA-592 and this version warrant a response value change to +FCLASS=2.1. There are devices in service for which the manufacturers claim conformance to very
42、early draft Industry Ballot versions of this Standard, particularly SP-2388, issued in 1990, responding +FCLASS=2. These devices do not meet the requirements of this Standard, unless they clarify that they meet both SP-2388 (Class 2) and TINEIA-592-A (Class 2.1). This standard supersedes the followi
43、ng TIA standards: TINEIA-592, TINEIA-605 and TIA-IS-134. Note 1 - References are made throughout the specifications to ITU-T (International Telecommunications Union) approved standards (called Recommendations“); a corresponding updated ANSlKlNElA specification for each reference may already exist at
44、 publication of this standard: Examples: ITU-Recommendation T.31 TIAIEIA-578-B (In progress) ITU-Recommendation V.25ter TINEIA-602 and TINEIA-615 ITU-Recommendation T.30 TINEIA-466-B (In progress) ITU-Recommendation T.4 TINEIA-465-B (In progress) 1 INTRODUCTION and SCOPE 1 .I Facsimile Terminals Gro
45、up 3 Facsimile machines were developed for sending digitized documents over the General Switched Telephone Network (GSTN). These facsimile terminals are now in widespread use around the world. The operation of Group 3 Facsirnile terminals has been standardized in Recommendations T.4, T.6 (MMR) and T
46、.30, and in TlNElA Standards TIAIEIA-465-A and TINEIA-466-A within the US. 1.2 Facsimile DCE There are two types of adapters that allow data terminal equipment (DTE) to communicate as Group 3 facsimile terminals. Some of these adapters are installed inside the DTE, on the processor bus; these are ca
47、lled “FAX boards“. Others are configured as an external “facsimile DCEn, connected to the DTE by a standard serial port (e.g. TINEIA-232-E, ITU-T V.24), using serial data interchange. TINEIAr578 defines a facsimile DCE (see Section 2.1). 1.3 Scope - This standard contains protocols for use between a
48、 DTE and a Facsimile DCE. It supports automatic calling and answering. This standard defines the commands that the DTE may issue to configure and control the DCE, and the responses the facsimile DCE shall issue to those commands. This standard is useful for intelligent DTEs and DTE software, facsimi
49、le DCEs, and facsimile terminals with digital connection to DTEs. This standard assumes that the DTE and DCE are connected via serial asynchronous connection using TINEIA-232-E (or V.24) circuits; it requires the provision of the Packet Protocol (Section 9) when used on serial ports. However, the protocols defined may be implemented in any environment that provides a character serial bidirectional data stream, including processor-bus-attached “fax boards“, local area networks, Small Computer Sys
