`
`Foreword
`
`This Global System for Mobile communications Technical Specification (GTS) has been produced by the
`Special Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards
`Institute (ETSI).
`
`This GTS specifies the AT command for terminal equipments being used within the digital cellular
`telecommunications system (Phase 2/Phase 2+).
`
`This GTS is a TC-SMG approved GSM technical specification version 5, which contains GSM Phase 2+
`enhancements/features to the version 4 GSM technical specification. The ETS from which this Phase 2+
`GTS has evolved is Phase 2 GSM prETS 300 642 (GSM 07.07 version 4.1.0).
`
`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 European
`Telecommunications Standards (ETS). This ensures the earliest possible access to GSM Phase 2+
`specifications for all Manufacturers, Network operators and implementors of the Global System for Mobile
`communications.
`
`The contents of this GTS are subject to continuing work within TC-SMG and may change following formal
`TC-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 5.x.y
`
`where:
`y
`
`the third digit is incremented when editorial only changes have been incorporated in the
`specification;
`
`x
`
`the second digit is incremented for all other types of changes, i.e. technical enhancements,
`corrections, updates, etc.
`
`NOTE:
`
`TC-SMG has produced documents which give the technical specifications for the
`implementation of the digital cellular telecommunications system. Historically, these
`documents have been identified as GSM Technical Specifications (GSM-TSs). These
`TSs may have subsequently become I-ETSs (Phase 1), or ETSs/ETSI Technical
`Reports (ETRs) (Phase 2). TC-SMG has also produced ETSI GSM TSs which give the
`technical specifications for the implementation of Phase 2+ enhancements of the
`digital cellular telecommunications system. These version 5.x.x GSM Technical
`Specifications may be referred to as GTSs.

`
`Scope
`
`This European Telecommunications Standard (ETS) specifies a profile of AT commands and
`recommends that this profile be used for controlling Mobile Equipment (ME) functions and GSM network
`services from a Terminal Equipment (TE) through Terminal Adaptor (TA). The command prefix +C is
`reserved for Digital Cellular in ITU-T Recommendation V.25ter [14]. This ETS has also the syntax details
`used
`to construct
`these extended GSM commands. Commands
`from
`ITU-T Recommendation
`V.25ter [14] and existing digital cellular standards (TIA IS-99 [15] and TIA IS-135 [16]) are used whenever
`applicable. Some of the new commands are defined such way that they can be easily applied to ME of
`networks other than GSM. ITU-T T.31 [11] and T.32 [12] fax AT commands may be used for GSM fax
`transmission from TE. GSM Short Message Service AT commands are defined in GSM 07.05 [24].
`
`This ETS assumes an abstract architecture comprising a TE (e.g. a computer) and a ME interfaced by a
`TA (see figure 1). The span of control of the defined commands should allow to handle any physical
`implementation 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 entity.
`
`The commands described in this ETS may be observed on the link between the TE and the TA. However,
`most of the commands retrieve information about the ME, not about the TA.

`Figure 1: Setup
`
`Interface between TE and TA is intended to operate over existing serial (ITU-T Recommendation V.24)
`cables, infrared link, and all link types with similar behaviour. For correct operation many of the defined
`commands require eight bit data and therefore it is recommended that TE-TA link is set to eight bits/ byte
`mode. (For infrared operation implementation refer informative references IrDA and TIA-617.) Interface
`between TA and ME is dependent on the interface in the ME.

`[...]
`
`Carriage return character, which value is specified with command S3.
`
`Linefeed character, which value is specified with command S4.
`
`Name enclosed in angle brackets is a syntactical element. Brackets themselves
`do not appear in the command line.
`
`Optional subparameter of a command or an optional part of TA information
`response is enclosed in square brackets. Brackets themselves do not appear in
`the command line. When subparameter is not given in parameter type
`commands, new value equals to its previous value. In action type commands,
`action should be done on the basis of the recommended default setting of the
`subparameter.

`GSM 07.07 Version 5.0.0: July 1996
`
`underline
`
`Underlined defined subparameter value is the recommended default setting of
`this subparameter. In parameter type commands, this value should be used in
`factory settings which are configured by V.25ter [14] command &F0. In action
`type commands, this value should be used when subparameter is not given.

`
`AT command syntax
`
`This clause summarizes general aspects on AT commands and issues related to them. For further
`information refer ITU-T Recommendation V.25ter [14].
`
`4.1
`
`Command line
`
`See figure 2 for general structure of a command line. Standardized basic commands are found only in
`V.25ter [14]. GSM commands use syntax rules of extended commands. Every extended command has a
`test command (trailing =?) to test the existence of the command and to give information about the type of
`its subparameters. Parameter type commands also have a read command (trailing ?) to check the current
`values of subparameters. Action type commands do not store the values of any of their possible
`subparameters, and therefore do not have a read command.
`
`subparameter

`read command for checking
`current subparameter values

`
`extended commands are

`

`
`Figure 2: Basic structure of a command line
`
`If verbose responses are enabled with command V1 and all commands in a command line has been
`performed successfully, result code <CR><LF>OK<CR><LF> is sent from the TA to the TE. If numeric
`responses are enabled with command V0, result code 0<CR> is sent instead.
`
`If verbose responses are enabled with command V1 and subparameter values of a command are not
`accepted by the TA (or command itself is invalid, or command cannot be performed for some reason),
`result code <CR><LF>ERROR<CR><LF> is sent to the TE and no subsequent commands in the command
`line are processed. If numeric responses are enabled with command V0, result code 4<CR> is sent
`instead. ERROR (or 4) response may be replaced by +CME ERROR: <err> (refer clause 9) when
`command was not processed due to an error related to ME operation.

`
`Information responses and result codes
`
`The TA response for the example command line of figure 2 could be as shown in figure 3. Here, verbose
`response format is enabled with command V1. If numeric format V0 would have been used, <CR><LF>
`headers of information responses would have been left out and final result code changed to 0<CR>.

`CONNECT), and so called unsolicited result codes indicate occurrence of an event not directly associated
`with issuance of a command from TE (e.g. ring indication RING).

`mand. response formatting character (recommended default IRA 10)
`mand. command line editing character (recommended default IRA 8)
`mand. command echo (recommended default 1 i.e. TA echoes commands
`back)
`mand. result code suppression (recommended default 0 i.e. TA transmits
`result codes)
`mand. TA response format (recommended default 1 i.e. verbose format)
`mand. defines CONNECT result code format; values manufacturer specific
`mand. determines how ITU-T V.24 circuit 109 (or equivalent) relates to the
`detection of received line signal from remote end (recommended
`default 1 i.e. 109 operation relates to detection of received signal)
`mand. determines how TA responds when ITU-T V.24 circuit 108/2 (or
`equivalent) is changed from ON to OFF condition during online data

`
`General commands
`
`ITU-T Recommendation V.25ter [14] includes "Generic DCE Control" commands with the prefix +G. These
`commands are for the identification of the TA. Four of those commands are adapted here to be the
`identification commands of the ME. Syntax is otherwise similar but the prefix is +CG. TIA IS-99 [15] uses
`same commands for ME identification.
`
`5.1
`
`Request manufacturer identification +CGMI
`
`Table 2: +CGMI action command syntax
`
`Command
`+CGMI
`
`+CGMI=?
`
`Possible response(s)
`<manufacturer>
`+CME ERROR: <err>
`
`Description
`
`Execution command causes the TA to return one or more lines of information text <manufacturer>,
`determined by the ME manufacturer, which is intended to permit the user of the TA to identify the
`manufacturer of the ME to which it is connected to. Typically, the text will consist of a single line containing
`the name of the manufacturer, but manufacturers may choose to provide more information if desired.
`Refer subclause 9.2 for possible <err> values.
`
`Defined values
`
`<manufacturer>:
`
`the total number of characters, including line terminators, in the information text
`shall not exceed 2048 characters.
`
`Text shall not contain the sequence 0<CR> or OK<CR>
`
`Implementation
`
`Optional.

`
`Request model identification +CGMM

`Table 3: +CGMM action command syntax
`
`Command
`+CGMM
`
`+CGMM=?
`
`Possible response(s)
`<model>
`+CME ERROR: <err>
`
`Description
`
`Execution command causes the TA to return one or more lines of information text <model>, determined
`by the ME manufacturer, which is intended to permit the user of the TA to identify the specific model of the
`ME to which it is connected to. Typically, the text will consist of a single line containing the name of the
`product, but manufacturers may choose to provide more information if desired. Refer subclause 9.2 for
`possible <err> values.
`
`Defined values
`
`<model>:
`
`the total number of characters, including line terminators, in the information text shall not
`exceed 2048 characters.
`
`Text shall not contain the sequence 0<CR> or OK<CR>
