GM29 Modem 2.1 Description The dual band EGSM 900/1800MHz GM29 is a GSM/GPRS serial modem. The modem is a powerful and flexible device that can be used in a wide range of telemetry and telematics applications that rely on the remote exchange of data, voice, SMS or faxes via the GSM cellular network. Small and lightweight, the GM29 has standard connectors and an integral SIM card reader making it easy and quick to integrate. As well as providing a standard RS232 serial communication interface the GM29 also has an audio interface allowing an analogue handset to be connected. When the GM29 is integrated into an external application, a wireless communications system is created. A typical end-to-end system consists of a micro controller in an external application communicating, via the GM29 modem, with a remote terminal or host using the GSM network. The micro controller uses a set of AT commands to control the modem, and to set up the end-to-end communications link, via its 9-way RS232 serial interface. GM29 serial modems are intended to be used by manufacturers, system integrators, application developers and developers of a wide range of equipment and business solutions, typically in the following fields: • Security and alarms • Vending • Monitoring and control • Utilities • Fleet Management 2.2 Highlights • • • • • • • • • • • Dual band, EGSM 900/1800MHz, GSM/GPRS serial modem Flexible plug-and-play device Data: GPRS, HSCSD, CSD, SMS Voice: full rate, enhanced full rate, half rate SMS: mobile-originated, mobile-terminated, cell broadcast Fax: Group 3, Classes 1 & 2 RS232 9-way serial interface 5V - 32V d.c. input 4-wire audio connection Antenna connection (FME male) R&TTE type approved 14 LZT 123 7361 R1A 2.

The definitions in the figure, as used elsewhere in this manual, are in accordance with the recommendations of GSM 07.07. • The MS (mobile station) represents the GM29 modem plus SIM card. The modem excluding SIM card, is known as the ME (mobile equipment). • The TE (terminal equipment) is a micro-controller (i.e., a computer) and is a part of the application. Wireless Communication System GSM Network Application TE (DTE) ME status, responses AT commands to control MS MS (GM29) Figure 2.1 Main Blocks in a Wireless System In accordance with the recommendations of ITU-T (International Telecommunication Union - Telecommunications Standardisation Sector) V.24, the TE communicates with the MS over a serial interface. The functions of the GM29 follow the recommendations provided by ETSI (European Telecommunications Standards Institute) and ITU-T. ETSI specifies a set of AT commands for controlling the GSM element of the modem; these commands are supplemented by Sony Ericsson specific commands. To find out how to work with AT commands, see “Part 3: Using AT Commands”, page 51. 15 LZT 123 7361 R1A GM29 INTEGRATOR’S MANUAL Figure 2.2 illustrates the interface between the modem and the application.

Electrical Description All electrical connections to the GM29 are protected in compliance with 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 Connector An 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. 6 5 4 3 1 VCC 2 n/c 2 1 3 HR_IN 4 TO_IN 5 n/c 6 GND 28 LZT 123 7361 R1A 2.

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 GM29 is turned ON, it will reset. 32 LZT 123 7361 R1A 2. ELECTRICAL DESCRIPTION 2.5 RS232 Serial Port The 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 GM29 serial modem should be considered as the data circuit-terminating equipment (DCE) and the external application or computer as the data terminating equipment (DTE). 6 7 8 9 1 2 3 4 5 1 DCD 2 RD 3 TD 4 DTR 5 GND 6 DSR 7 RTS 8 CTS 9 RI The electrical characteristics of the serial port signals are shown below: Pin Signal Dir Voltage levels Description 1 DCD O > +4V < –4V Data carrier detect 2 RD O > +4V < –4V Received data 3 TD I > 2V < 0.8V Transmitted data 4 DTR I > 2V < 0.8V Data terminal ready 5 GND - 0V Ground connection 6 DSR O > +4V < –4V Data set ready 7 RTS I > 2V < 0.8V Request to send 8 CTS O > +4V < –4V Clear to send 9 RI O > +4V < –4V Ring indicator 33 LZT 123 7361 R1A GM29 INTEGRATOR’S MANUAL 2.5.1 Serial Data The 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, TD The default baud rate is 9.6kbps, however higher bit rates up to 460kbps are supported. At start-up the GM29 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, RI RTS 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. 34 LZT 123 7361 R1A 2. ELECTRICAL DESCRIPTION Data 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, settable 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 Clock The GM29 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 GM29 provides back-up power to maintain the RTC for at least 12 hours. 2.7 Software Updates It is possible and sometimes necessary to update the GM29 software. Updates must be carried out by a Sony Ericsson approved technician. Please contact your supplier for details (see “Service and Support”, page 9). 35 LZT 123 7361 R1A GM29 INTEGRATOR’S MANUAL 3. Operation 3.1 Switching On the Modem There 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 Modem There 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 Modem A 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. 36 LZT 123 7361 R1A 3. OPERATION 3.4 Operating States/LED The modem has a green LED, as depicted below, which is used to indicate various operating states. These states are described in following table. LED Notes! Operating State LED Status After switching on the modem On after 4s Switch off (Power down) or power removed Off Standby or talk Flashing No network, network search, no SIM card, no PIN entered On Switch off (Power Down): DC power is applied but the modem is switched OFF. Standby: The GM29 is switched ON and camped on to the network. No call in progress. Talk: The GM29 is switched ON and a voice/data call is in progress. 37 LZT 123 7361 R1A GM29 INTEGRATOR’S MANUAL 4. Hints for Integrating the Modem This chapter gives you advice and helpful hints on how to integrate the GM29 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 Precautions 4.1.1 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 GM29. Note, Sony Ericsson does not warrant against defects, nonconformities 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. 38 LZT 123 7361 R1A 4. HINTS FOR INTEGRATING THE MODEM • 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. • In the final application, the antenna must be positioned more than 20cm away from human bodies. When this rule cannot be applied, the application designer is responsible for providing the SAR measurement test report and declaration. 4.2 Installation of the Modem 4.2.1 Where to Install the Modem There 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: Environmental Conditions The 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. 39 LZT 123 7361 R1A GM29 INTEGRATOR’S MANUAL Signal Strength The 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 42. When an application is completed, you can verify signal strength by issuing the AT command AT+CSQ. See “AT+CSQ Signal Strength”, page 89. 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 length Connection of Components to GM29 The 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. 4.2.2 How to Install the Modem Power 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. 40 LZT 123 7361 R1A 4. HINTS FOR INTEGRATING THE 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 GM29 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 Antenna 4.3.1 General The 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; • 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 41 LZT 123 7361 R1A GM29 INTEGRATOR’S MANUAL 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 Type Make 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: EGSM/GSM900/1800; • the impedance of the antenna and antenna cable must be 50Ω; • 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 Placement The 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. In general, CE-marked products for residential and commercial areas, and light industry can withstand a minimum of 3V/m. 4.3.4 The Antenna Cable Use 50Ω impedance low-loss cable and high-quality 50Ω 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. Minimize 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 Disturbances Possible communication disturbances include the following: 42 LZT 123 7361 R1A 4. HINTS FOR INTEGRATING THE MODEM • 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 Accessories The GM29 has been type approved together with a range of accessories including: 1.

DECLARATION OF CONFORMITY 6. Declaration of Conformity 49 LZT 123 7361 R1A GM29 INTEGRATOR’S MANUAL 50 LZT 123 7361 R1A Part 3: Using AT Commands Product Photo/Illustration 1. Introduction to AT Commands 1.1 Overview AT 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 kit The GM29 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 Description This section provides a brief description of the syntax used for the GM29, AT command set. See the ITU-T recommendation V.25ter for additional information. 1.2.1 Conventions In this manual, the following conventions are used to explain the AT commands.The name of the command that is to be entered. The parameter values that are defined for a certain command. The command line is terminated by the Carriage Return (or Enter key) or ATS3 command. 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. 53 LZT 123 7361 R1A GM29 INTEGRATOR’S MANUAL [] 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: and CMS ERROR: (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 Syntax The 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 Command The format of basic syntax commands is as follows: AT [=][ ] Example! ATL=0 (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 Extended Syntax Command • AT+ = [ ] 54 LZT 123 7361 R1A 1. INTRODUCTION TO AT COMMANDS • AT* =[ ] Example! AT+CFUN=0 (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 Syntax The read command is used to check the current values of parameters. Type ‘?’, after the command line: • AT+ ? • AT* ? • AT ? Example! AT+CSCS? (show current character set) “IRA” (information text response) OK (final result code response) Test Command Syntax The test command is used to test whether the command has been implemented or to give information about the type of subparameters it contains. Type ‘?’, after the command line: • AT+ =? • AT* =? Example! AT+CPAS=? (shows supported values for the response parameters) CPAS: (0, 3, 4, 129, 130, 131) (supported values) OK (final result code) If the indicated is not recognized, the result code ERROR is issued. Note! Possible responses are indicated both as :(list of supported ) and (in most cases) the actual range of the parameter values. 1.2.3 AT Response Syntax The default mode response shown below, is in text mode. See the command V for further details. 55 LZT 123 7361 R1A GM29 INTEGRATOR’S MANUAL Possible 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+ : – AT* : where the is the result code value, note that a single space character separates the colon character from the . 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 . 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 Code A 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, + ERROR followed by an error code. Final result codes are: Value General meaning OK Command executed, no errors ERROR Invalid command or command line too long NO DIALTONE No dialling possible, wrong mode BUSY Remote station busy NO ANSWER Connection completion time-out NO CARRIER Link not established or disconnected Unsolicited Result Code Unsolicited result codes indicate the occurrence of an event not directly associated with a command being issued from the TE. 56 LZT 123 7361 R1A 1. INTRODUCTION TO AT COMMANDS 1.3 Error Codes 1.3.1 +CME ERROR (Mobile Equipment Error Code) This final result code is similar to the regular ERROR result code. If +CME ERROR: is the result code for any of the commands in a command line, none of the commands in the same command line will be executed (neither ERROR nor OK result code shall be returned as a result of a completed command line execution). The format of can be either numerical or alphabetical, and is set with the +CMEE command. The table below provides the numerical values for the parameter .

The operation is similar to the ERROR result code. None of the following commands in the same command line will be executed. Neither ERROR nor OK result code will be returned. ERROR is returned normally when an error is related to syntax or invalid parameters. Nevertheless, it always appears when a command fails. The syntax is as follows: +CMS ERROR: Values for the parameter are described in the following table.

Ericsson specific ATDL[;] ... Used to initiate a phone connection, which may be data or voice (phone number terminated by semicolon). The phone number used to establish the connection will consist of digits and modifiers, or a stored number specification. If the dial string is followed by a semicolon this informs the phone that the number is a voice rather than a data number. If the dial string is omitted, and the semicolon included, the command instructs the ME to do a network detect. If the network is available OK is returned. Abortability: Aborting an ATD command is accomplished by the transmission from the DTE to the DCE of any character. A single character shall be sufficient to abort the command in progress; however, characters 62 LZT 123 7361 R1A 2. CALL CONTROL transmitted during the first 125 milliseconds after transmission of the termination character are ignored. This is to allow the DTE to append additional control characters such as line feed after the command line termination character.

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 0 Single mode. Default value. In order to avoid accidental originating or answering of alternating calls is set to single mode in following cases: - after a successfully completed alternating mode call; - after a unsuccessful answering; - after successfully execution of the commands &F and Z 66 LZT 123 7361 R1A 2.
