line. Standardized basic commands are found only in V.250 [14]. GSM/UMTS 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. If verbose responses are enabled with command V1 and all commands in a command line has been performed successfully, result code OK is sent from the TA to the TE. If numeric responses are enabled with command V0, result code 0 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 ERROR 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 is sent instead. ERROR (or 4) response may be replaced by +CME ERROR: (refer clause 9) when command was not processed due to an error related to MT operation. 1.2 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, headers WCDMA Module of information responses would have been left out and final result code changed to 0 . So called intermediate result codes inform about progress of TA operation (e.g. connection establishment 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). 1.3 Abbreviations AT ATtention; this two-character abbreviation is always used to start a command line to be sent from TE to TA ASCI Advanced Speech Call Items, including VGCS, VBS and eMLPP BCD Binary Coded Decimal eMLPP Enhanced Multi-Level Precedence and Pre-emption Service ETSI European Telecommunications Standards Institute FTM Frame Tunnelling Mode (refer 3GPP TS 27.001 [41] and 3GPP TS 29.007[42]) HSCSD High Speed Circuit Switched Data IMEI International Mobile station Equipment Identity IRA International Reference Alphabet (ITU-T T.50 [13]) IrDA Infrared Data Association ISO International Standards Organization ITU-T International Telecommunication Union - Telecommunications Standardization Sector ME Mobile Equipment MoU Memorandum of Understanding (GSM operator joint) MT Mobile Termination PCCA Portable Computer and Communications Association PTT Push to Talk RDI Restricted Digital Information RLP Radio Link Protocol SIM Subscriber Identity Module TA Terminal Adaptor, e.g. a GSM data card (equal to DCE; Data Circuit terminating Equipment) TE Terminal Equipment, e.g. a computer (equal to DTE; Data Terminal Equipment) TIA Telecommunications Industry Association UDI Unrestricted Digital Information UE User Equipment WCDMA Module UICC Universal Integrated Circuit Card USIM Universal Subscriber Identity Module VBS Voice Broadcast Service VGCS Voice Group Call Service 2 General commands 2.1 +CGMI Request manufacturer identification Description Execution command causes the TA to return one or more lines of information text , determined by the MT manufacturer, which is intended to permit the user of the TA to identify the manufacturer of the MT to which it is connected to.

Their use in GSM/UMTS is listed in this subclause, as well as new dial modifiers applicable only to GSM/UMTS are introduced. For a MT supporting AT commands only, it is mandatory to support the control of supplementary services in accordance with 3GPP TS 22.030 [19] through the dial command or through the specific supplementary service commands (+CCFC, +CLCK, etc.), where 3GPP TS 22.030 [19] identifies the supplementary services as mandatory. V.250 dialling digits 1 2 3 4 5 6 7 8 9 0 * # + A B C (implementation of these characters is mandatory for GSM/UMTS) D (implementation of this character is optional for GSM/UMTS, and it is ignored) V.250 modifier characters , (implementation of this character is mandatory for GSM/UMTS, but it may be ignored) T P (implementation of these characters is mandatory for GSM/UMTS, but they are ignored) ! W @ (implementation of these characters is optional for GSM/UMTS, and they are ignored) V.250 semicolon character In GSM/UMTS, when semicolon character is given after dialling digits (or modifiers), a voice call originated to the given address. TA returns to command state immediately (or after possible +COLP result code; refer subclause "Connected line identification presentation +COLP"). Refer Annex G for a detailed example. GSM/UMTS modifier characters > (refer subclause "Direct dialling from phonebooks") I or i (override the CLIR supplementary service subscription default value for this call; I = invocation (restrict CLI presentation) and i = suppression (allow CLI presentation); refer subclause "Calling line identification restriction +CLIR") G or g (control the CUG supplementary service information for this call; uses index and info values set with command +CCUG; refer subclause "Closed user group +CCUG") 3.2 +CSTA Select type of address Description Set command selects the type of number for further dialling commands (D) according to GSM/UMTS specifications. Test command returns values supported a compound value. 13 WCDMA Module Command +CSTA=[ ] +CSTA? +CSTA=? Defined values : type of address octet in integer format (refer TS 24.008 [8] subclause 10.5.4.7); default 145 when dialling string includes international access code character "+", otherwise 129 3.3 +CMOD Call mode Description Set command selects the call mode of further dialling commands (D) or for next answering command (A). Mode can be either single or alternating (in the present document, terms "alternating mode" and "alternating call" refer to all GSM/UMTS bearer and teleservices that incorporate more than one basic service (voice, data, fax) within one call). When single mode is selected the call originating and hangup procedures are similar to procedures specified in ITU-T Recommendations V.250 [14], T.31 [11] and T.32 [12]. In GSM/UMTS there can be voice followed by data (refer 3GPP TS 22.002 [1]), alternating voice/data (refer 3GPP TS 22.002 [1]) and alternating voice/fax calls (refer 3GPP TS 22.003 [2]). Refer next two subclauses for alternating call control methods. Command +CMOD=[ ] +CMOD? +CMOD=?

It is defined in the Enter GPRS Data Mode (+CGDATA) command. 3.8 +CEER Extended error report Description Execution command causes the TA to return one or more lines of information text , determined by the MT manufacturer, which should offer the user of the TA an extended report of the reason for - the failure in the last unsuccessful call setup (originating or answering) or in-call modification; - the last call release; - the last unsuccessful GPRS attach or unsuccessful PDP context activation; - the last GPRS detach or PDP context deactivation. Typically, the text will consist of a single line containing the cause information given by GSM/UMTS network in textual format. Command +CEER +CEER: +CEER=? Defined values : the total number of characters, including line terminators, in the information text shall not exceed 2041 characters. 3.9 +CRC Cellular result codes Description Set command controls whether or not the extended format of incoming call indication or GPRS network request for PDP context activation or notification for VBS/VGCS calls is used. When enabled, an incoming call is indicated to the TE with unsolicited result code +CRING: instead of the normal RING. Test command returns values supported as a compound value.

The optional proposes a layer 2 protocol to use between the MT and the TE. It is defined in the Enter GPRS Data Mode (+CGDATA) command. If the MT is unable to announce to the TE the network's request (for example it is in V.250 online data state) the MT shall reject the request. No corresponding unsolicited result code shall be issued when the MT returns to a command state. is a part of the group call reference as specified in 3GPP TS 23.003 [7] and indicates group call area. is a part of the group call reference as specified in 3GPP TS 23.003 [7] and indicates group call identification.The =1 proposes that a predefined confirmation procedure is to be used after the call is ended. For =0 no confirmation procedure is required. 19 WCDMA Module 3.10 +CVHU Voice Hangup Control Description Set command selects whether ATH or "drop DTR" shall cause a voice connection to be disconnected or not. By voice connection is also meant alternating mode calls that are currently in voice mode. (See subclause 6.6). Command +CVHU=[ ] Defined values +CVHU? +CVHU: +CVHU=? +CVHU:(list of supported s) : 0 "Drop DTR" ignored but OK response given. ATH disconnects. 1 "Drop DTR" and ATH ignored but OK response given. 2 "Drop DTR" behaviour according to &D setting. ATH disconnects. 3.11 +VGR Receive gain selection Description This refers to the amplification by the TA of audio samples sent from the TA to the computer. The command operates on an integer , range 0...255. Values larger than 128 indicate a larger gain than nominal. Values less than 128 indicate a smaller gain than nominal. The entire range of 0...255 does not have to be provided. A value of zero implies the use of automatic gain control by the TA. Command +VGR= +VGR? +VGR=? (list of supported s) +VGR= +VGR? 3.12 +CMUT Mute control Description This command is used to enable and disable the uplink voice muting during a voice call. Refer subclause 9.2 for possible values. Test command returns supported values as compound value. Command +CMUT= +CME +CMUT? +CMUT: +CME ERROR: Defined values : 0 mute off 1 mute on 20 WCDMA Module 3.13 +VTD Tone duration Description This refers to an integer that defines the length of tones emitted as a result of the +VTS command. This does not affect the D command. A value different than zero causes a tone of duration /10 seconds. The value zero causes a "manufacturer specific" value. Command +VTD= +VTD? +VTD=? (list of supported s) +VTD= Defined values +VTD? : 0 mute off 1 mute on 3.14 +VTS DTMF and tone generation Description This command allows the transmission of DTMF tones and arbitrary tones (see note). These tones may be used (for example) when announcing the start of a recording period. The command is write only. In this profile of commands, this command does not operate in data or fax modes of operation (+FCLASS=0,1,2-7). Command +VTS=as above +VTS=? (list Defined values 1. . A single ASCII character in the set 0-9, #,*,A-D. This is interpreted as a single ACSII character whose duration is set by the +VTD command. NOTE 2: In GSM this operates only in voice mode. 2. [ , , ]. This is interpreted as a dual tone of frequencies and , lasting for a time (in 10 ms multiples). NOTE 3: This does not operate in GSM. 3. { , }. This is interpreted as a DTMF tone of different duration from that mandated by the +VTD command. 3.15 +CLCC List current calls Description Returns list of current calls of MT. If command succeeds but no calls are available, no information response is sent to 21 WCDMA Module TE. Refer subclause 9.2 for possible values.
