Chapter 1 – Introduction 1.5 Supported Character Sets The ME supports two character sets: GSM 03.38 (7 bit, also referred to as GSM alphabet or SMS alphabet) and UCS2 (16 bit, refer to ISO/IEC 10646). See AT+CSCS for information about selecting the character set. Character tables can be found below. Explanation of terms • International Reference Alphabet (IRA) IRA means that one byte is displayed as two characters in hexadecimal format.
Chapter 1 – Introduction 1.5.1 GSM Alphabet Tables and UCS2 Character Values This section provides tables for the GSM 03.38 alphabet supported by the ME. Below any GSM character find the corresponding two byte character value of the UCS2 alphabet. Figure 1.1: Main character table of GSM 03.38 alphabet 1. 2. This code is an escape to the following extension of the 7 bit default alphabet table. This code is not a printable character and therefore not defined for the UCS2 alphabet.
Chapter 1 – Introduction Figure 1.2: Extension character table of GSM 03.38 alphabet 1. This code value is reserved for the extension to another extension table. On receipt of this code, a receiving entity shall display a space until another extension table is defined. 2. This code represents the EURO currency symbol. The code value is the one used for the character ‘e’. Therefore a receiving entity which is incapable of displaying the EURO currency symbol will display the character ‘e’ instead. 3.
Chapter 1 – Introduction 1.5.2 UCS2 and GSM Data Coding and Conversion for SMS Text Mode This section provides basic information on how to handle input and output character conversion for SMS text mode and Remote-SAT if the internal (TA) and external (TE) character representation differ; e.g., if the Data Coding Scheme and the TE character use different coding. 1.5.2.
Chapter 1 – Introduction 1.5.2.2 Implementing Input of Terminal Data to SIM (Direction TE to TA) Used Character DCS = 7 bit DCS = 8 bit DCS = 16 bit Set GSM Data UCS2 GSM UCS2 Case 1 GSM (1:1) Case 4 GSM to IRA (1:4) Case 2 IRA to 8 bit (2:1) Case 5 8 bit to IRA (1:4) Case 3 IRA to 16 bit (4:2) Case 6 UCS2 to IRA (2:4) Note: The ratio between the number of input characters and bytes stored on the SIM is given in parentheses.
Chapter 1 – Introduction 1.6 Serial Interface Flow Control Flow control is essential to prevent loss of data or avoid errors when, in a data or fax call, the sending device is transferring data faster than the receiving side is ready to accept. When the receiving buffer reaches its capacity, the receiving device should be capable to cause the sending device to pause until it catches up. There are basically two approaches to regulate data flow: Software flow control and hardware flow control.
Chapter 1 – Introduction For most of these messages, the ME needs to be configured whether or not to send a URC. Depending on the AT command, the URC presentation mode can be saved to the user defined profile (see AT&W), or needs to be activated every time you reboot the ME. Several URCs are not user definable, such as “^SYSSTART”, “^SYSSTART ”, “^SHUTDOWN”.
Chapter 1 – Introduction 1.8 Common PCN Handset Specification (CPHS) The ME provides features to implement a device following the prerequisites of the Common PCN Handset Specification (CPHS) Phase 2. CPHS Feature Description/Remarks AT command Alternate Line Service Voice Message Waiting Indication Operator (Service provider) name from SIM Network and Service Provider Lock Call Forwarding Customer Service Profile (CSP) Information numbers Using two phone numbers with one SIM card.

Chapter 2 – Configuration Commands 2.9 AT+CFUN Set Phone Functionality Description: This command serves to control the functionality level of the mobile equipment (ME). It can be used to reset the ME, to choose one of the SLEEP modes, or to return to full functionality. Intended for power saving, SLEEP mode reduces the functionality of the ME to a minimum and thus minimizes the current consumption.
Chapter 2 – Configuration Commands The parameter can only be used if the serial interface is enabled. Due to the command syntax, you need to enter parameter , followed by , where is only a placeholder and has no effect. See examples below. 0 Placeholder for as stated above. Default. 1 ME resets and restarts to full functionality. After reset and restart, PIN 1 authentication is necessary (AT+CPIN).
Chapter 2 – Configuration Commands 2.10 AT^SMSO Switch off Mobile Station Description: AT^SMSO initiates the power-off procedure. High level of the module’s PWR_IND and the URC “^SHUTDOWN” notifies that the procedure has completed and the module has entered the POWER DOWN mode. Therefore, be sure not to disconnect the operating voltage until PWR_IND is High or until the URC “^SHUTDOWN” is displayed. Otherwise, you run the risk of losing data. For further details on how to turn off the module see the [2].

Chapter 4 – Serial Interface Control Commands Chapter 5. Security Commands The AT Commands described in this chapter allow the external application to determine various security related settings. 5.1 AT+CPIN PIN Authentication Description: AT+CPIN controls network authentication of the Multi-Tech wireless modem. The read command returns an alphanumeric string indicating whether or not network authentication is required. The write command allows the Multi-Tech wireless modem to store the entered password.
Chapter 4 – Serial Interface Control Commands PH-NET PUK ME is waiting for network personalization unblocking password. PH-NS PIN ME is waiting for network subset personalization password. PH-NS PUK ME is waiting for network subset unblocking password. PH-SP PIN ME is waiting for service provider personalization password. PH-SP PUK ME is waiting for service provider personalization unblocking password. PH-C PIN ME is waiting for corporate personalization password.
Chapter 4 – Serial Interface Control Commands 5.2 AT+CPIN2 PIN2 Authentication Description: AT+CPIN2 controls network authentication of the Multi-Tech wireless modem. The read command returns an alphanumeric string indicating whether or not network authentication is required. The write command allows the Multi-Tech wireless modem to store the entered password. This may be, for example, the SIM PIN2 to benefit from the features listed below or the SIM PUK2 to replace a disabled PIN2 with a new one.
Chapter 4 – Serial Interface Control Commands 5.3 AT^SPIC Display PIN Counter Description: The AT^SPIC command can be used to find out whether the ME is waiting for a password and, if so, how many attempts are left to enter the password. The execute command returns the number of attempts still available for entering the currently required password, for example the PIN, PUK, PH-SIM PUK etc.
Chapter 4 – Serial Interface Control Commands Examples: Example 1 The user fails to provide a correct SIM PIN three times. The counter decreases each time. After the counter reaches zero, the SIM PUK is required. After each failure to enter a correct SIM PUK, the counter decreases.
Chapter 4 – Serial Interface Control Commands Example 3 This example shows that after successful SIM PIN1 authentication the counter of the AT^SPIC execute and read command refers to SIM PIN2; i.e., it does not reflect the status of SIM PIN1. This may be a problem if the user enters a wrong PIN1 and is not aware that the number of attempts left to enter SIM PIN1 is counted down.
Chapter 4 – Serial Interface Control Commands 5.4 AT+CLCK Facility Lock Description: AT+CLCK can be used to lock, unlock or interrogate a network or ME . The command can be aborted when network facilities are being set or interrogated.
Chapter 4 – Serial Interface Control Commands Factory Defined SIM Locks: Typical examples of factory set SIM locks are prepaid phones or network locks, used to restrict the operation of a mobile to a specific provider or operator. The client should be aware that each of these lock types can only be unlocked if the associated password is available. For example, a mobile can be locked to accept only SIM cards from the respective provider, or even one single SIM card.
Chapter 4 – Serial Interface Control Commands Notes: • The AT+CLCK command offers the full range of parameters according to the GSM specifications. However, when you attempt to use a service option which is not provisioned or not yet subscribed to, the setting will not take effect regardless of the response returned. The responses in these cases vary with the network (for example “OK”, “Operation not allowed”, “Operation not supported” etc.).
Chapter 4 – Serial Interface Control Commands 5.5 AT^SLCK Facility Lock Description: AT^SLCK provides the “Facility lock” function as defined for the GSM 07.07 command AT+CLCK. The command can be used to lock, unlock or interrogate a network or ME . AT^SLCK is, in every respect, identical with AT+CLCK, except that the command syntax and response prefix is “^SLCK” instead of “+CLCK”. For further details please refer to AT+CLCK.
Chapter 4 – Serial Interface Control Commands Once the Master Phone Code has been acctepted, the mobile is operational and the “PS” lock is no longer active. If needed it must be set once again with AT+CLCK. “P2“ SIM PIN 2; e.g., required for authentication with facility lock “FD” (cf. AT+CLCK). If incorrectly entered three times, the SIM PUK 2 is required to perform authentication. Input of the SIM PUK 2 password is possible only with AT command AT+CPIN2 or ATD.
Chapter 4 – Serial Interface Control Commands Example 4: To specify a new “PS” lock password To specify a new “PS” lock password, after the old password was disabled (e.g., after three failed attempts to change the “PS” password): use the master phone code.
