The ETS from which this Phase 2+GTS has evolved is Phase 2 GSM prETS 300 642 (GSM Version ).GTS are produced by TC-SMG to enable the GSM Phase 2 + specifications to become publicly available,prior to submission for the formal ETSI standards approval procedure to become EuropeanTelecommunications Standards (ETS).

6 This ensures the earliest possible access to GSM Phase 2+specifications for all Manufacturers, Network operators and implementors of the global System for contents of this GTS are subject to continuing work within TC-SMG and may change following formalTC-SMG approval. Should TC-SMG modify the contents of this GTS it will then be republished by ETSI with an identifying change of release date and an increase in Version number as follows: Version :ythe third digit is incremented when editorial only changes have been incorporated in thespecification;xthe second digit is incremented for all other types of changes, technical enhancements,corrections, updates, :TC-SMG has produced documents which give the technical specifications for theimplementation of the Digital cellular telecommunications system.

7 Historically, thesedocuments have been identified as GSM Technical Specifications (GSM-TSs). TheseTSs may have subsequently become I-ETSs (Phase 1), or ETSs/ETSI TechnicalReports (ETRs) (Phase 2). TC-SMG has also produced ETSI GSM TSs which give thetechnical specifications for the implementation of Phase 2+ enhancements of thedigital cellular telecommunications system. These Version GSM TechnicalSpecifications may be referred to as 6 GSM Version : July 1996 Blank pagePage 7 GSM Version : July 19961 ScopeThis European Telecommunications Standard (ETS) specifies a profile of AT commands andrecommends that this profile be used for controlling Mobile Equipment (ME) functions and GSM networkservices from a Terminal Equipment (TE) through Terminal Adaptor (TA).

8 The command prefix +C isreserved for Digital cellular in ITU-T Recommendation [14]. This ETS has also the syntax detailsused to construct these extended GSM commands. Commands from ITU-T [14] and existing Digital cellular standards (TIA IS-99 [15] and TIA IS-135 [16]) are used wheneverapplicable. Some of the new commands are defined such way that they can be easily applied to ME ofnetworks other than GSM. ITU-T [11] and [12] fax AT commands may be used for GSM faxtransmission from TE. GSM Short Message Service AT commands are defined in GSM [24].This ETS assumes an abstract architecture comprising a TE ( a computer) and a ME interfaced by aTA (see figure 1). The span of control of the defined commands should allow to handle any physicalimplementation that this abstract architecture may lead to:-TA, ME and TE as three separate entities;-TA integrated under the ME cover, and the TE implemented as a separate entity;-TA integrated under the TE cover, and the ME implemented as a separate entity;-TA and ME integrated under the TE cover as a single commands described in this ETS may be observed on the link between the TE and the TA.

9 However,most of the commands retrieve information about the ME, not about the cmdsresponsesME controlME statusUSER & APPLICATIONSNETWORK network messagesFigure 1: SetupInterface between TE and TA is intended to operate over existing serial (ITU-T Recommendation )cables, infrared link, and all link types with similar behaviour. For correct operation many of the definedcommands require eight bit data and therefore it is recommended that TE-TA link is set to eight bits/ bytemode. (For infrared operation implementation refer informative references IrDA and TIA-617.) Interfacebetween TA and ME is dependent on the interface in the ETS incorporates by dated and undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listedhereafter.
