GM28 INTEGRATOR’S MANUAL28LZT 123 7468 P1A2. Electrical DescriptionAll electrical connections to the GM28 are designed to meet the standard air (4kV) and contact (8kV) discharge ESD tests, of EN 301 489-1.The modem uses the following industry standard connectors:• RJ11 6-way (power connector)• RJ9 4-way (handset connector)• SIM card reader• FME male coaxial jack (antenna connector)• Sub-D socket, 9 pin (RS232 serial port)2.1 Power ConnectorAn RJ11 6-way connector, as shown and described below, serves as a means of supplying and controlling d.c. power to the modem.The supply voltage, VCC, required by the modem is in the range 5V - 32V d.c. Application of the supply voltage does not switch the modem on. To do so an additional active-high control signal, TO_IN, must be applied for > 0.2s.A second active-high control signal, HR_IN, can be used to switch the modem off when applied for 1 - 2 seconds, or can be used to perform a hardware reset when applied for > 3.5s.TO_IN and HR_IN are referenced to GND (pin 6 on the connector).VCC and GND are reverse polarity and overvoltage protected.6543211 VCC2 n/c3 HR_IN4 TO_IN5 n/c6 GND

GM28 INTEGRATOR’S MANUAL32LZT 123 7468 P1A2.4 SIM Card ReaderThe GM28 is fitted with a SIM card reader designed for 3V and 5V SIM cards. It is the flip-up type which is lockable in the horizontal position and is accessed through a removable panel as shown below.The SIM card reader includes a SIM presence switch. This ensures that when a SIM card is inserted or removed while the GM28 is turned ON, it will reset.
2. ELECTRICAL DESCRIPTION33LZT 123 7468 P1A2.5 RS232 Serial PortThe modem supports a standard RS232 serial interface (EIA/TIA 574) via its 9 pin Sub-D connector, shown below. In line with serial communication terminology the GM28 serial modem should be considered as the data circuit-terminating equipment (DCE) and the external application or computer as the data terminating equipment (DTE).The electrical characteristics of the serial port signals are shown below:Pin Signal Dir Voltage levelsDescription1DCD O> +4V< –4VData carrier detect2 RD O > +4V< –4VReceived data3TD I> 2V< 0.8VTransmitted data4 DTR I > 2V< 0.8VData terminal ready5GND -0V Ground connection6DSR O > +4V< –4VData set ready7RTS I> 2V< 0.8VRequest to send8 CTS O > +4V< –4VClear to send9RI O> +4V< –4VRing indicator91 DCD2RD3TD4 DTR5 GND6 DSR7RTS8 CTS9RI76543218
GM28 INTEGRATOR’S MANUAL34LZT 123 7468 P1A2.5.1 Serial DataThe modem supports the standard data character format of 1 start bit, 8 bit data, no parity plus 1 stop bit, in total 10 bits per character.2.5.2 Serial Data Signals - RD, TDThe default baud rate is 9.6kbps, however higher bit rates up to 460kbps are supported. At start-up the GM28 transmits and receives data at the default rate of 9.6kbps in either standard AT mode or binary mode (the first received data - AT or binary format - determines the operating mode). When reprogramming, the transmission rate is automatically negotiated by the programming application. Speeds up to 460kbps are supported.Serial Data From Modem (RD)RD is an output signal that the modem uses to send data to the application.Serial Data To Modem (TD)TD is an input signal, used by the application to send data to the modem.2.5.3 Control Signals - RTS, CTS, DTR, DSR, DCD, RIRTS and CTS are capable of transmitting at 1/10th of the data transmission speed for data rates up to 460kbps (byte-oriented flow control mechanism).Request to Send (RTS)Used to condition the DCE for data transmission. The default level is high by internal pull up.The exact behaviour of RTS is defined by an AT command. Software or hardware control can be selected. Hardware flow is the default control.The application must pull RTS low to communicate with the modem. The modem will respond by asserting CTS low, indicating it is ready for communication.Clear To Send (CTS)CTS indicates that the DCE is ready to transmit data. The default level is high. You can define the exact behaviour of CTS through an AT command, and can select software or hardware flow control.
2. ELECTRICAL DESCRIPTION35LZT 123 7468 P1AData Terminal Ready (DTR)DTR indicates that the DTE is ready to transmit and receive data. It also acts as a hardware ‘hang-up’, terminating calls when switched high. The signal is active low. You can define the exact behaviour of DTR with an AT command.The DTR line can also be used to switch on the modem when activated for 0.2 seconds. The DTR line must be deactivated prior to switching off the modem to ensure it switches off (powers down) correctly.Data Set Ready (DSR)An active DSR signal is sent from the modem to the application (DTE) to confirm that a communications path has been established. DSR has two modes of operation, which can be set using the AT command AT&S.Data Carrier Detect (DCD)DCD indicates that the DCE is receiving a valid carrier (data signal) when low. You can define the exact behaviour of DCD with an AT command.Ring Indicator (RI)RI indicates that a ringing signal is being received by the DCE when low. You can define the exact behaviour or RI with an AT command.2.6 Real Time ClockThe GM28 contains a real time clock (RTC) to maintain accurate timekeeping and to enable “timestamping” of messages.The RTC is powered when d.c. power is connected to the modem AND the modem is switched on. If the d.c. supply fails, a stored energy device within the GM28 provides back-up power to maintain the RTC for at least 12 hours.2.7 Software UpdatesIt is possible and sometimes necessary to update the GM28 software. Updates must be carried out by a Sony Ericsson approved technician. Please contact your supplier for details (see “Service and Support”, page 20).
GM28 INTEGRATOR’S MANUAL36LZT 123 7468 P1A3. Operation3.1 Switching On the ModemThere are two ways to switch on the modem, once power is applied.• either assert TO_IN high for > 0.2s;• or activate the RS232 control line DTR, high for > 0.2s.The modem is fully operational after 4 seconds. Logging onto a network may take longer than this and is outside the control of the modem.The modem can be configured to start up at the time power is applied by permanently tying power connector signals TO_IN (pin 4) and VCC (pin 1) together. In this case DTR must be used to switch the modem on again after it has been switched off or reset, while power is still applied.3.2 Switching Off the ModemThere are two ways to switch off (power down) the modem as described below:• either use the AT+CFUN command;• or assert HR_IN high for 1 - 2 seconds. A delay of up to 10s is experienced as the modem logs off the network.Note! The DTR line must be deactivated prior to switching off the modem to ensure the unit switches off correctly.3.3 Resetting the ModemA full system reset, independent of the status of the software, may be applied to the modem as follows:• assert HR_IN high for > 3.5s.

GM28 INTEGRATOR’S MANUAL38LZT 123 7468 P1A4. Hints for Integrating the ModemThis chapter gives you advice and helpful hints on how to integrate the GM28 into your application from a hardware perspective.Please read and consider the information under the following headings before starting your integration work:• Safety advice and precautions.• Installation of the modem.• Antenna.4.1 Safety Advice and Precautions4.1.1 General• Always ensure that use of the modem is permitted. The modem may present a hazard if used in proximity to personal medical electronic devices. As a rule, the modem must not be used in hospitals, airports or planes.• Avoid exposing the modem to lighted cigarettes, naked flames or to extreme hot or cold temperature.• You are responsible for observing your country’s safety standards, and where applicable the relevant wiring rules.• Never use the modem at a gas station, refuelling point, blasting area or in any other environment where explosives may be present.• Operating the modem close to other electronic devices, such as antennas, television sets, and radios may cause electromagnetic interference.• Never try to dismantle the modem yourself. There are no components inside the modem that can be serviced by the user. If you attempt to dismantle the modem, you may invalidate the warranty.• To protect power supply cables and meet the fire safety requirements when the unit is powered from a battery or a high current supply, connect a fast 1.25A fuse in line with the positive supply.• Do not connect any incompatible component or product to the GM28. Note, Sony Ericsson does not warrant against defects, non-conformities or deviations caused thereby.4.1.2 SIM Card• Before handling the SIM card in your application, ensure that you are not charged with static electricity. Use proper precautions to avoid electrostatic discharges.
4. HINTS FOR INTEGRATING THE MODEM39LZT 123 7468 P1A• When the SIM card hatch is opened, the SIM card connectors lie exposed under the SIM card holder. CAUTION: Do not touch these connectors! If you do, you may release an electrical discharge that could damage the modem or the SIM card.• When designing your application, the SIM card’s accessibility should be taken into account. We always recommend that you have the SIM card protected by a PIN code. This will ensure that the SIM card cannot be used by an unauthorized person.4.1.3 Antenna• If the antenna is to be mounted outside, consider the risk of lightning. Follow the instructions provided by the antenna manufacturer.• Never connect more than one modem to a single antenna. The modem can be damaged by radio frequency energy from the transmitter of another modem.• Like any mobile station, the antenna of the modem emits radio frequency energy. To avoid EMI (electromagnetic interference), you must determine whether the application itself, or equipment in the application’s proximity, needs further protection against radio emission and the disturbances it might cause. Protection is secured either by shielding the surrounding electronics or by moving the antenna away from the electronics and the external signals cable.• The modem and antenna may be damaged if either come into contact with ground potentials other than the one in your application. Beware, ground potential are not always what they appear to be.• If the application containing the GM28 uses an antenna which is less than 20cm away from any part of the user’s body, integrators are legally obliged to publish SAR figures for the product. SAR testing is the responsibility of the system integrator.• Even if SAR measurements are not required it is considered good practice to insert a warning in any manual produced, indicating it is a radio product and that care should be taken.• The GM28 module is FCC approved for fixed and mobile applications. If the final product after integration is intended for portable use, a new application and FCC ID is required.4.2 Installation of the Modem4.2.1 Where to Install the ModemThere are several conditions which need to be taken into consideration when designing your application as they might affect the modem and its function. They are:
GM28 INTEGRATOR’S MANUAL40LZT 123 7468 P1AEnvironmental ConditionsThe modem must be installed so that the environmental conditions stated in the Technical Data chapter, such as temperature, humidity and vibration are satisfied. Additionally, the electrical specifications in the Technical Data section must not be exceeded.Signal StrengthThe modem has to be placed in a way that ensures sufficient signal strength. To improve signal strength, the antenna can be moved to another position. Signal strength may depend on how close the modem is to a radio base station. You must ensure that the location at which you intend to use the modem, is within the network coverage area. Degradation in signal strength can be the result of a disturbance from another source, for example an electronic device in the immediate vicinity. More information about possible communication disturbances can be found in section 4.3.5, page 43.When an application is completed, you can verify signal strength by issuing the AT command AT+CSQ. See “AT+CSQ Signal Strength”, page 87.Tip! Before installing the modem, use an ordinary mobile telephone to check a possible location for it. In determining the location for the modem and antenna, you should consider signal strength as well as cable lengthConnection of Components to GM28The integrator is responsible for the final integrated system. Incorrectly designed or installed, external components may cause radiation limits to be exceeded. For instance, improperly made connections or improperly installed antennas can disturb the network and lead to malfunctions in the modem or equipment.Network and Subscription• Before your application is used, you must ensure that your chosen network provides the necessary telecommunication services. Contact your service provider to obtain the necessary information.• If you intend to use SMS in the application, ensure this is included in your (voice) subscription.• Consider the choice of the supplementary services described in section “2.4.2 Short Message Service”, page 17.• Please be aware that compliance with AMR may be required by certain network operators.
4. HINTS FOR INTEGRATING THE MODEM41LZT 123 7468 P1A4.2.2 How to Install the ModemPower Supply• Use a high-quality power supply cable with low resistance. This ensures that the voltages at the connector pins are within the allowed range, even during the maximum peak current.• When the unit is powered from a battery or a high current supply, connect a fast 1.25A fuse in line with the positive supply. This protects the power cabling and modem.Securing the modem• Before securing the modem take into account the amount of additional space required for the mating connectors and cables that will be used in the application.• Where access is restricted, it may be easier to connect all the cables to the modem prior to securing it in the application.• Securely attach the GM28 modem to the host application using two 3mm diameter pan-head screws of appropriate length as shown below.Caution! Do not exceed a torque of 25Ncm when tightening the fixings screws. Excessive torque applied to the screws can crack the plastic case.4.3 Antenna4.3.1 GeneralThe antenna is the component in your system that maintains the radio link between the network and the modem. Since the antenna transmits and receives electromagnetic energy, its efficient function will depend on:• the type of antenna (for example, circular or directional);• the placement of the antenna;
GM28 INTEGRATOR’S MANUAL42LZT 123 7468 P1A• communication disturbances in the vicinity in which the antenna operates.In the sections below, issues concerning antenna type, antenna placement, antenna cable, and possible communication disturbances are addressed.In any event, you should contact your local antenna manufacturer for additional information concerning antenna type, cables, connectors, antenna placement, and the surrounding area. You should also determine whether the antenna needs to be grounded or not. Your local antenna manufacturer might be able to design a special antenna suitable for your the application.4.3.2 Antenna TypeMake sure that you choose the right type of antenna for the modem. Consider the following requirements:• the antenna must be designed for the dual frequency bands in use: GSM850/1900;• the impedance of the antenna and antenna cable must be 50:;• the antenna output-power handling must be a minimum of 2W;• the VSWR value should be less than 3:1 to avoid damage to the modem.4.3.3 Antenna PlacementThe antenna should be placed away from electronic devices or other antennas. The recommended minimum distance between adjacent antennas, operating in a similar radio frequency band, is at least 50cm.If signal strength is weak, it is useful to face a directional antenna at the closest radio base station. This can increase the strength of the signal received by the modem.The modem’s peak output power can reach 2W. RF field strength varies with antenna type and distance. At 10cm from the antenna the field strength may be up to 70V/m and at 1m it will have reduced to 7V/m.4.3.4 The Antenna CableUse 50:impedance low-loss cable and high-quality 50:impedance connectors (frequency range up to 2GHz) to avoid RF losses. Ensure that the antenna cable is as short as possible.The Voltage Standing-Wave Ratio (VSWR) may depend on the effectiveness of the antenna, cable and connectors. In addition, if you use an adapter between the antenna cable and the antenna connector, it is crucial that the antenna cable is a high-quality, low-loss cable.
4. HINTS FOR INTEGRATING THE MODEM43LZT 123 7468 P1AMinimize the use of extension cables, connectors and adapters. Each additional cable, connector or adapter causes a loss of signal power.4.3.5 Possible Communication DisturbancesPossible communication disturbances include the following:•Noise can be caused by electronic devices and radio transmitters.•Path-loss occurs as the strength of the received signal steadily decreases in proportion to the distance from the transmitter.•Shadowing is a form of environmental attenuation of radio signals caused by hills, buildings, trees or even vehicles. This can be a particular problem inside buildings, especially if the walls are thick and reinforced.•Multi-path fading is a sudden decrease or increase in the signal strength. This is the result of interference caused when direct and reflected signals reach the antenna simultaneously. Surfaces such as buildings, streets, vehicles, etc., can reflect signals.•Hand-over occurs as you move from one cell to another in the GSM network. Your mobile application call is transferred from one cell to the next. Hand-over can briefly interfere with communication and may cause a delay, or at worst, a disruption.4.4 AttachmentsThe GM28 has been FCC certified using a number of attachments including:1.

Product Photo/Illustration Part 3: Using AT Commands
51LZT 123 7468 P1A1. Introduction to AT Commands1.1 OverviewAT commands, issued from a computer in your application are used to control and implement the functions of the modem.Using AT commands, the following actions are possible:• Control of DCE•GPRS• Call control• Supplementary Service• SIM application tool kitThe GM28 contains a large number of Ericsson-specific commands in addition to those implemented in accordance with the GSM and ITU-T recommendations. These commands are provided to enhance the functions of the modem. The Ericsson-specific commands are identified by the asterisk that precedes the command (see the syntax description provided below).1.2 Syntax DescriptionThis section provides a brief description of the syntax used for the GM28, AT command set. See the ITU-T recommendation V.25ter for additional information.1.2.1 ConventionsIn this manual, the following conventions are used to explain the AT commands.<command> The name of the command that is to be entered.<parameter> The parameter values that are defined for a certain command. <CR> The command line is terminated by the Carriage Return (or Enter key) or ATS3 command.<LF> Line feed character or ATS4 command.< > The term enclosed in angle brackets is a syntactical element. The brackets do not appear in the command line.
GM28 INTEGRATOR’S MANUAL52LZT 123 7468 P1A[ ] Square brackets are used to indicate that a certain item is optional. For example, sub-parameters of a command or an optional part of a response. The brackets do not appear in the command line.Value The default values of the supported parameters are indicated by using bold text when presenting the value.• Other characters, including ‘?’, ‘ ’, parenthesis, etc., appear in commands and responses as written.• The final result codes OK, ERROR, +CME ERROR: <err> and CMS ERROR:<err> (see sections 1.2.3, AT Response Syntax and 1.3, Error Codes) are not listed under “Possible Responses” for each AT command. • OK and ERROR are listed if these are the only possible responses.1.2.2 AT Command SyntaxThe AT standard is a line-oriented command language. Each command is made up of the following three elements:• the prefix;• the body;• the termination character.The prefix consists of the letters “AT”, which are derived from the first two letters of the word attention. The body is made up of the command, the parameter, and if applicable the associated values.Commands may be combined in the same command line. Spaces between the individual bodies are ignored.Basic Syntax CommandThe format of basic syntax commands is as follows:AT<command>[=][<parameter>]<OK>Example! ATL=0<CR> (sets the volume of the speaker)Additional commands may follow a command on the same command line without any character being required for separation. For the command D parameters, see the description for the command in question.A version of the basic syntax is:AT<command><parameter>Extended Syntax Command• AT+<command>= [<parameter>]
1. INTRODUCTION TO AT COMMANDS53LZT 123 7468 P1A• AT*<command>=[<parameter>]Example! AT+CFUN=0<CR> (powers down the modem)If several values are included in the command, they are separated by commas. It is also possible to enter commands with no values.Additional commands may follow an extended syntax command on the same command line if a semicolon (; IRA 3B) is inserted after the preceeding extended command as a separator.Read Command SyntaxThe read command is used to check the current values ofparameters. Type ‘?’, after the command line:• AT+<command>?• AT*<command>?• AT<command>?Example! AT+CSCS?<CR> (show current character set)<CR>“IRA”<CR>(information text response)<CR>OK<CR>(final result code response)Test Command SyntaxThe test command is used to test whether the command has beenimplemented or to give information about the type of subparameters itcontains. Type ‘?’, after the command line:• AT+<command>=?• AT*<command>=?Example! AT+CPAS=?<CR> (shows supported values for the response parameters)<CR>CPAS: (0, 3, 4, 129, 130, 131)<CR> (supported values)<CR>OK<CR> (final result code)If the indicated <parameter> is not recognized, the result code ERROR is issued.Note! Possible responses are indicated both as <command>:(list of supported<parameter>) and (in most cases) the actual range of the parameter values.1.2.3 AT Response SyntaxThe default mode response shown below, is in text mode.

GM28 INTEGRATOR’S MANUAL54LZT 123 7468 P1APossible formats for the result codes are:• Basic format result code, such as OK. The Basic result code also has a numerical equivalent.• Extended format result code, prefixed with a plus sign (+) or an asterisk (*):– AT+<command>: <parameter >– AT*<command>: <parameter>where the <parameter> is the result code value, note that a single space character separates the colon character from the <parameter>If several values are included in the result code, they are separated by commas. It is also possible that a result code has no value. The extended syntax result codes have no numerical equivalent. They are always issued in alphabetical form.• Information text response may contain multiple lines separated by <CR>. The TE detects the end of informational text responses by looking for a final result code response, such as OK.There are two types of result code responses as outlined below:Final Result CodeA final result code indicates to the TE that execution of the command is completed and another command may be issued.• If you type an implemented AT command, you should get the result code OK.• If you type an AT command that is not implemented, or which had the wrong parameter or syntax, you will get an error result code. It is ERROR or, for example, +<command> ERROR followed by an error code.Final result codes are:Value General meaningOK Command executed, no errorsERROR Invalid command or command line too longNO DIALTONE No dialling possible, wrong modeBUSY Remote station busyNO ANSWER Connection completion time-outNO CARRIER Link not established or disconnectedUnsolicited Result CodeUnsolicited result codes indicate the occurrence of an event not directly associated with a command being issued from the TE.

GM28 INTEGRATOR’S MANUAL64LZT 123 7468 P1A2.10 AT+CMOD Call ModeSelects the call mode of further dialing commands (D) or for next answering command (A). Mode can be either single or alternating. In this ETS, terms “alternating mode” and “alternating call” refer to all GSM 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 hang-up procedures are similar to procedures specified in ITU-T Recommendations V.25ter, T.31 and T.32. In GSM there can be voice followed by data (refer to GSM 02.02), alternating voice/data (refer to GSM 02.02) and alternating voice/fax calls (refer to GSM 02.03).Test command returns values supported by the TA as a compound value.Note! +CMOD is set to zero after a successfully completed alternating mode call. It is set to zero also after a failed answering. The power-up, factory (&F) and user resets (Z), also set the value to zero. This reduces the possibility that alternating mode calls are originated or answered accidentally.Description Command Possible ResponsesRequest Call Mode AT+CMOD=[<mode>] •OK•ERRORShows the current settingAT+CMOD? • +CMOD: <mode>•OK•ERRORShow if the command is supportedAT+CMOD=? • +CMOD: (list of supported <mode>s)•OK•ERROR<mode> Description0Single mode.

Voice connection also includes alternating mode calls that are currently in voice mode.Note! When <mode>=2, this command must be viewed in conjunction with the V.25ter command &D, or &D will be ignored.2.12 AT+VTS DTMF and Tone GenerationThis command allows the transmission of DTMF tones. 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, the command does not operate in data or fax modes of operation (+FCLASS=0,1,2-7).Note! The ATD-command is used only for dialing.

Extended error responses (enabled by the +CMEE command) are listed under “+CME ERROR (Mobile Equipment Error Code)”, page 55.Any active PDP contexts will be automatically deactivated when the attachment state changes to detached.Note!

16. SUPPLEMENTARY SERVICES249LZT 123 7468 P1A16.13 AT+CHLD Call Hold and MultipartyThis command allows control of the following call related services:• a call can be temporarily disconnected from the ME but the connection is retained by the network;• multiparty conversation (conference calls);• the served subscriber who has two calls (one held and the other either active or alerting) can connect the other parties and release the served subscriber's own connection.Calls can be put on hold, recovered, released, added to conversation, and transferred similarly as defined in 3GPP TS 22.030.This is based on the GSM/UMTS supplementary services HOLD (Call Hold; refer 3GPP TS 22.083 clause 2), MPTY (MultiParty; refer 3GPP TS 22.084) and ECT (Explicit Call Transfer; refer 3GPP TS 22.091). The interaction of this command with other commands based on other GSM/UMTS supplementary services is described in the GSM/UMTS standards.Note! Call Hold and MultiParty are only applicable to teleservice 11.It is recommended (although optional) that test command returns a list of operations which are supported. The call number required by some operations is denoted by “x” (e.g. +CHLD: (0,0x,1,1x,2,2x,3)).Description Command Possible ResponsesRequest call related supplementary servicesAT+CHLD=<n> • +CME ERROR <err>•OK•ERRORShow if the command is supportedAT+CHLD=? • +CHLD: (list of supported <n>s)• +CME ERROR <err>•OK•ERROR<n> Description...

GM28 INTEGRATOR’S MANUAL250LZT 123 7468 P1A“X” is the numbering (starting with 1) of the call given by the sequence of setting up or receiving the calls (active, held or waiting) as seen by the served subscriber. Calls hold their number until they are released. New calls take the lowest available number. Where both a held and a waiting call exists, the above procedures shall apply to the waiting call (i.e. not to the held call) in conflicting situation.Note! The “directory number” case shall be handled with dial command D, and the END case with hangup command H (or +CHUP).16.14 AT+CLIP Call Line Identification PresentationThis command enables a called subscriber to get the identity of the calling line when receiving a mobile terminated call. The “Set” command enables or disables the presentation of the CLI (calling line identity) at the TE. It has no effect on the execution of the supplementary service CLIP in the network.When the presentation of the CLI at the TE is enabled (if the calling subscriber has allowed it), the unsolicited result code +CLIP:<number>,<type>,,,<alpha> response is returned after every RING (or +CRING:<type>) result code sent from TA to TE (refer to AT +CRC in section ???????).Whether this will be used when a normal voice call is answered is a manufacturer-specific option.2 Places all active calls (if any exist) on hold and accepts the other (held or waiting) call2X Places all active calls on hold, except call X with which communication is supported3 Adds a held call to the conversation4Connects the two calls and disconnects the subscriber from both calls (explicit call transfer)<n> DescriptionDescription Command Possible ResponsesRequests calling line identification.AT+CLIP=<n> OKRead the current settingAT+CLIP? +CLIP: <n>,<m>Show if the command is supportedAT+CLIP=? +CLIP: (list of supported <n>s)<n> Description0Disables presentation.

The set command enables or disables the presentation of notification result codes from TA to TE.When <n>=1 and a supplementary service notification is received after a mobile originated call setup, unsolicited result code +CSSI: <code1>[,<index>] is sent to TE before any other MO call setup result codes presented in this ETS or in V.25ter. When several different <code1>s are received from the network, each of them shall have its own +CSSI result code.When <m>=1 and a supplementary service notification is received during a mobile terminated call setup or during a call, or when a forward check supplementary service notification is received, unsolicited result code +CSSU: <code2>[,<index>] is sent to TE. In case of MT call setup, result code is sent after every +CLIP result code (refer command “Calling line identification presentation +CLIP”) and when several different <code2>s are received from the network, each of them shall have its own +CSSU result code.Note! The difference between <index> and <cindex> is that <index> is a position mark while <cindex> is a unique value for each CUG. <index> is not supported.Test command returns values supported by the TA as a compound value.Description Command Possible ResponsesPresentation of notification result codes from TA to TEAT+CSSN=[<n>[,<m>]] • +CME ERROR <err>•OK•ERRORRead the current settingAT+CSSN? • +CSSN: <n>,<m>• +CME ERROR <err>•OK•ERRORTest if the command is supportedAT+CSSN=? • +CSSN: (list of supported <n>s),(list of supported <m>s)• +CME ERROR <err>•OK•ERROR<n> Description0Disable the +CSSI result code presentation status in the TA1 Enable the +CSSI result code presentation status in the TA

SUPPLEMENTARY SERVICES255LZT 123 7468 P1A16.17 AT+CUSD Unstructured Supplementary Service DataThis command allows control of the Unstructured Supplementary Service Data (USSD) according to GSM 02.90. Both network and mobile initiated operations are supported. Parameter <n> is used to disable/enable the presentation of an unsolicited result code (USSD response from the network, or network initiated operation) +CUSD: <m>[,<str>,<dcs>] to the TE. In addition, value <n>=2 is used to cancel an ongoing USSD session. If <n> is not given then the default value 0 is taken.When <str> is given, a mobile initiated USSD string or a response USSD string to a network initiated operation is sent to the network. The response USSD string from the network is returned in a subsequent unsolicited +CUSD: result code.The interaction of this command with other commands based on other GSM supplementary services is described in the GSM standard.Test command returns values supported by the TA as a compound value.Some different scenarios are shown below:• An incoming network initiated USSD-Notify should be presented to the external application as an unsolicited result code +CUSD: if the external application has enabled result code presentation.• An incoming USSD-request asking for a reply should sent to the external application as an unsolicited result code +CUSD: if the external application has enabled result code.• If the external application answers to the request with the command AT+CUSD then the ME sends the answer to the network.• A USSD-request sent with the command AT+CUSD from the external application.Description Command Possible ResponsesRequest unstructured supplementary service dataAT+CUSD=[<n>[,<str>]] • +CME ERROR: <err>•OKShow supported message types along with the current service settingAT+CUSD? • +CUSD: <n>•OK•ERRORShow list of supported servicesAT+CUSD=? • +CUSD: (list of supported <n>s)•OK•ERROR
