2.12.1 Reset signal
Signal Function I/O Pin
RESET Phone reset I/O 23 (connector SO301)
RESET is used to reset the Telit TRIZIUM module. Whenever this signal is pulled low, the TRIZIUM is reset. When the device is reset it stops any operation and after the release of the reset it shuts down, without doing any detach operation from the network where it is registered to. This behavior is not a proper shut down because any GSM device is requested to issue a detach request on turn off. For this reason the Reset signal must not be used to normally shutting down the device, but only as an emergency exit in the rare case the device remains stucked waiting for some network response.
The RESET is internally controlled on start-up to achieve always a proper power-on reset sequence, so there's no need to control this pin on start-up. It may only be used to reset a device already on that is not responding to any command.
NOTE: do not use this signal to power off the Telit TRIZIUM module. Use the ON/OFF signal (Pin 17 of SO301) to perform this function or the AT#SHDN command.
Reset Signal Operating levels:
Signal Min Max
RESET Input high 2.2V* 3.3V RESET Input low 0V 0.2V
* this signal is internally pulled up so the pin can be left floating if not used. If unused, this signal may be left unconnected. If used, then it must always be connected with an open collector transistor, to permit to the internal circuitry the power on reset and undervoltage lockout functions.

2.13 RTC Bypass out
The PIN VRTC brings out the Real Time Clock supply which is separate from the rest of the digital part, allowing to have only RTC going on when all the other parts of the device are off. To this power output a backup capacitor can be added in order to increase the RTC autonomy during power off of the battery. NO Devices must be powered from this pin.
2.14 Vout power output
A regulated power supply output is provided in order to supply small devices from module. This output is active when the module is ON and goes off when module is shut down. The operating range characteristics of the supply are:

2.15 Audio levels specifications
The audio of the Telit TRIZIUM module is organized into two main paths:
- internal path (called also MT)
- external path (called also HF) These two paths are meant respectively for handset and headset/handsfree use. The Telit TRIZIUM module has a built in echo canceller and a noise suppressor, tuned separately for the two audio paths; for the internal path the echo canceller parameters are suited to cancel the echo generated by a handset, while for the external audio path they are suited for a handsfree use. For more information on the audio refer to the Hardware User Guide. The following table reports all the audio level specifications.

3 Evaluation Kit
In order to assist you in the development of your Telit TRIZIUM module based application, Telit can supply an Evaluation
Kit (same as used for the GM862 family, with a dedicated adaptor) with appropriate power supply, SIM card housing,
RS 232 serial port level translator, direct UART connection, Handset, Headset and Hands-free (car kit) audio, antenna.
The EVK provides a fully functional solution for a complete data/phone application. The standard serial RS232 9 pin connector placed on the Evaluation Kit allows the connection of the
EVK system with a PC or other DTE. The development of the applications utilizing the Telit TRIZIUM module must present a proper design
of all the interfaces towards and from the module (e.g. power supply, audio paths, level translators), otherwise a decrease in the performances will be introduced or, in the worst case, a wrong design can even lead to an operating failure of the module.
In order to assist the hardware designer in his project phase, the EVK board presents a series of different solutions, which will cover the most common design requirements on the market, and which can be easily integrated in the OEM design as building blocks or can be taken as starting points to develop a specific one.

5 AT Command
The Telit TRIZIUM module can be driven via the serial interface using the standard AT commands1. The Telit TRIZIUM
module is compliant with:
1. Hayes standard AT command set, in order to maintain the compatibility with existing SW programs.
2. ETSI GSM 07.07 specific AT command and GPRS specific commands.
3. ETSI GSM 07.05 specific AT commands for SMS (Short Message Service) and CBS (Cell Broadcast Service)
4. FAX Class 1 compatible commands
Moreover the Telit TRIZIUM module supports also Telit proprietary AT commands for special purposes. In the following the dedicated description of how to use the AT commands with the Telit TRIZIUM module.
5.1 Definitions
The following syntactical definitions apply: <CR> Carriage return character, is the command line and result code terminator character, which value, in decimal ASCII between 0 and 255,is specified within parameter S3. The default value is 13. <LF> Linefeed character, is the character recognised as line feed character. Its value, in decimal ASCII between 0 and 255, is specified within parameter S4. The default value is 10. The line feed character is output after carriage return character if verbose result codes are used (V1 option used ) otherwise, if numeric format result codes are used (V0 option used) it will not appear in the result codes.
<...> Name enclosed in angle brackets is a syntactical element. They 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 AT commands which have a read command, new value equals to its previous value. In AT commands which do not store the values of any of their subparameters, and so have not a read command, which are called action type commands, action should be done on the basis of the recommended default setting of the subparameter.
5.2 AT Command Syntax
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. There are two types of extended command:
- Parameter type commands which 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.
5.2.1 Command lines
The basic structure of the command lines are:
ATCMD1<CR> where AT is the command line prefix, CMD1 is a basic command (i.e. it have not + prefix) and
CR is the command line terminator character
ATCMD2=10<CR> where 10 is a subparameter
AT+CMD1;+CMD2=, ,10<CR> These are two examples of extended commands (which have a + prefix). They are
delimited with semicolon. In the second command the subparameter is omitted
+CMD1?<CR> This is a read command for checking current subparameter values
1
The AT is an ATTENTION command and is used as a prefix to other parameters in a string. The AT command combined with other parameters can be set up in the communications package or typed in manually as a command line instruction.

Telit TRIZIUM Product Description
80264ST10007a Rev. 4– 09/09/04
+CMD1=?<CR> This is a test command for checking possible subparameter values These commands might be performed in a single command line as shown below: ATCMD1 CMD2=10+CMD1;+CMD2=, ,10;+CMD1?;+CMD1=?<CR> anyway it is always preferable to separate into different command lines the basic commands (i.e. without + prefix) and the extended commands (the ones with + prefix); furthermore it is suggested to avoid placing several action commands in the same command line, because if one of them fails, then an error message is received but it is not possible to argue which one of them has failed the execution. If command V1 is enabled (verbose responses codes) 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 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 and no subsequent commands in the command line are processed. If command V0 is enabled (numeric responses codes), and all commands in a command line has been performed successfully, result code 0<CR> is sent from the TA to the TE, if sub-parameter 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 4<CR> and no subsequent commands in the command line are processed. In case of errors depending on ME operation, ERROR (or 4) response may be replaced by +CME ERROR: <err> or +CMS ERROR: <err>.

80264ST10007a Rev. 4– 09/09/04
5.2.2 Information responses and result codes
The TA response, in case of verbose response format enabled, for the previous examples command line could be as shown below: information response to +CMD1? <CR><LF>+CMD1:2,1,10<CR><LF> information response to +CMD1=? <CR><LF>+CMD1(0-2),(0,1),(0-15)<CR><LF> final result code <CR><LF>OK<CR><LF>
Moreover there are other two types of result codes:
result codes that inform about progress of TA operation (e.g. connection establishment CONNECT)
result codes that indicate occurrence of an event not directly associated with issuance of a command from TE (e.g.
ring indication RING).
Here the basic result codes according to ITU-T V25Ter recommendation
Result Codes
Numeric form Verbose form 0 OK 1 CONNECT 2 RING 3 NO CARRIER 4 ERROR 6 NO DIALTONE 7 BUSY 8 NO ANSWER
5.2.3 Command Response Timeout
Every command issued to the Telit TRIZIUM module returns a result response if response codes are enabled (default). The time needed to process the given command and return the response varies from command to command and may depend also from the network on which the command may interact. As a result every command is provided with a proper timeout time, if this time elapses without any result from the operation, then an ERROR response can be reported as if the operation was not successful and the operation is anyway terminated. The timeout time is quite short for commands that imply only internal set up commands, but may be very long for command that interact with the network (or even a set of Networks). The default timeout is 100 ms for all the commands that have no interaction with the network or upper software layers. In the table below are listed all the commands whose timeout differs from the default 100 ms and their effective timeout is reported:

5.2.4 Command issuing timing
The chain Command -> Response shall always be respected and a new command must not be issued before the TRIZIUM has terminated all the sending of its response result code (whatever it may be). This applies especially to applications that "sense" the OK text and therefore may send the next command before the complete code <CR><LF>OK<CR><LF> is sent by the TRIZIUM. It is advisable anyway to wait for at least 20ms between the end of the reception of the response and the issue of the next AT command. If the response codes are disabled and therefore the module does not report any response to the command, then at least the 20ms pause time shall be respected. During command mode, due to hardware limitations, under severe CPU load the serial port can loose some characters if placed in autobauding at high speeds. Therefore if you encounter this problem fix the baud rate with AT+IPR command.
5.2.5 Factory Profile and parameters stored in the profile
The TRIZIUM stores several command configurations in the internal non volatile memory (see command &W), allowing to remember this status even after power off. The parameters that are stored in the profile and their are:
GSM DATA MODE : +CBST: 0,0,1 AUTOBAUD : +IPR: 0 COMMAND ECHO : E1 RESULT MESSAGES : Q1 VERBOSE MESSAGES : V1 EXTENDED MESSAGES : X1 FLOW CONTROL OPTIONS : &K3 CTS (C106) OPTIONS : &B2 DSR (C107) OPTIONS : &S3 DTR (C108) OPTIONS : &D0 DCD (C109) OPTIONS : &C1 RI (C125) OPTIONS : \R1 C108/1 OPERATION : &D4 POWER SAVING : +CFUN: 1 DEFAULT PROFILE : &Y0

Note: if parameter <cmd> is omitted then network is not interrogated. Note2: In the query command the class parameter must not be issued. Note3: The difference between call waiting report disabling (AT+CCWA = 0,1,7) and call waiting service disabling (AT+CCWA = 0,0,7) is that in the first case the call waiting indication is sent to the device by network but this last one does not report it to the DTE; instead in the second case the call waiting indication is not generated by the network. Hence the device results busy to the third party in the 2 case while in the 1st case a ringing indication is sent to the third party. Note4: The command AT+CCWA=1,0 is a non sense and must not be issued.

Note: The phone functionality remains always FULL.
Write command
AT+CFUN=<fun>
Enables/disables the power saving function. If enabled it reduces the power consumption during the idle time, thus allowing a longer standby time with a given battery capacity. Parameters: <fun>: is the power saving function mode 1 - Mobile full functionality with power saving disabled (default) 5 - Mobile full functionality with power saving enabled Note: To place the telephone in power saving mode, set the <fun> parameter at value = 5 and the line DTR (RS232) must be set to OFF. Once in power saving, the CTS line switch to the OFF status to signal that the telephone is really in power saving condition. During the power saving condition, before sending any AT command on the serial line, the DTR must be enabled and it must be waited for the CTS (RS232) line to go in ON status. Until the DTR line is ON, the telephone will not return back in the power saving condition.
Note2: The power saving function does not affect the network behavior of the TRIZIUM, even during the power save condition the module remains registered on the network and reachable for incoming calls or SMS. If a call incomes during the power save, then the module will wake up and proceed normally with the unsolicited incoming call code

Note: Pin pending status at startup depends on PIN facility setting, to change or query the default power up setting use the AT+CLCK=SC,<mode>, <pin> command.
Write command AT+CPIN =
<pin>[,<newpin>]
Sends to the device a password (SIM PIN, SIM PUK, PH-SIM PIN, etc.) which may be required to further operate the device. If the PIN required is SIM PUK or SIM PUK2, the <newpin> is required. This second pin, <newpin>,will replace the old pin in the SIM.
The command may be used to change the SIM PIN by sending it with both parameters <pin> and <newpin> when if PIN request is pending; if no PIN request is pending the command will return an error code and to change the PIN the command +CPWD must be used instead.
Parameters: <pin>, <newpin>
Note: the only commands which are accepted when device is pending SIM PIN, SIM PUK, or PH-SIM are: +CGMI, +CGMM, +CGMR, +CGSN, D112; (emergency call), +CPAS, +CPIN. To check the status of the PIN request use the command AT+CPIN?
Test command Example AT+CMEE=1
OK AT+CPIN? +CME ERROR: 10 (error because you have to insert the SIM)
AT+CPIN? +CPIN: READY (this response is after you have inserted the SIM)
OK
