To control your GSM engine you can simply send AT Commands via its serial interface. The controlling device at the other end of the serial line is referred to as TE (Terminal Equipment), DTE (Data Terminal Equipment) or plainly 'the application' (probably running on an embedded system). All abbreviations and acronyms used throughout this document are based on the GSM specifications. For definitions please refer to TR 100 350 V7.0.0 (1999-08), (GSM 01.04, version 7.0.0 release 1998). 1.3.1 Quick reference table Each AT command description includes a table similar to the example shown below. The table is intended as a quick reference to indicate the following functions: PIN: Is the AT command PIN protected? % Yes ! No § Usage is dependent on conditions specified for the command, or not all command types are PIN protected (for example write command PIN protected, read command not). Note: The table provided in Section 20.3, Available AT Commands and Dependency on SIM PIN uses the same symbols. ASC0: Is the AT command supported on the first physical serial interface ASC0? % Yes ! No ASC1: Is the AT command supported on the second physical serial interface ASC1? % Yes ! No MUXn: Is the AT command usable on the Multiplexer channels MUX1, MUX2, MUX3? % Yes ! No § AT command is usable, but under the restrictions specified in the section related to the command. Note: The columns MUX1, MUX2 and MUX3 are relevant only when the GSM engine operates in Multiplexer mode, that is, when the first physical serial interface is partitioned into 3 virtual channels by using the Multiplexer protocol. Usage is the same on ASC0 and MUX1. Is the AT command supported in ALARM mode? % Yes ! No Charge: Is the AT command supported in CHARGE ONLY mode? % Yes ! No § AT command is usable, but under the restrictions specified in the section related to the command. Last: If commands are concatenated, this AT command must be the last one. % Yes !

To terminate a command line enter <CR>. Commands are usually followed by a response that includes "<CR><LF><response><CR><LF>". Throughout this document, only the responses are presented, <CR><LF> are omitted intentionally. Table 1.4: Types of AT commands and responses AT command type Syntax Function Test command AT+CXXX=? The mobile equipment returns the list of parameters and value ranges set with the corresponding Write command or by internal processes. Read command AT+CXXX? This command returns the currently set value of the parameter or parameters. Write command AT+CXXX=<...> This command sets user-definable parameter values. Exec(ution) command AT+CXXX The execution command reads non-variable parameters determined by internal processes in the GSM engine. 1.4.1 • • • • • • • Using Parameters Optional parameters are enclosed in square brackets. If optional parameters are omitted, the current settings are used until you change them. Optional parameters or subparameters can be omitted unless they are followed by other parameters. If you want to omit a parameter in the middle of a string it must be replaced by a comma. See also example 1. A parameter value enclosed in square brackets represents the value that will be used if an optional parameter is omitted. See also example 2. When the parameter is a character string, e.g. <text> or <number>, the string must be enclosed in quotation marks, e.g. "Charlie Brown" or "+49030xxxx". Symbols in quotation marks will be recognized as strings. All spaces will be ignored when using strings without quotaton marks. It is possible to omit the leading zeros of strings which represent numbers. If an optional parameter of a V.250 command is omitted, its value is assumed to be 0. Example 1: Omitting parameters in the middle of a string AT+CCUG? +CCUG: 1,10,1 OK AT+CCUG=,9 OK AT+CCUG? +CCUG: 1,9,1 OK Query current setting Set only the middle parameter Query new setting Example 2: Using default parameter values for optional parameters AT+CFUN=5 OK AT+CFUN? +CFUN: 5 OK AT+CFUN= OK +CFUN: 1 OK MC55_ATC_V04.00 Confidential / Released Activate CYCLIC SLEEP mode, don't reset ME Query ME mode Set ME back to normal (default parameters: 1,0) Page 17 of 475 3/17/06 1.4.2 Combining AT commands on the same command line You may enter several AT commands on the same line. This eliminates the need to type the "AT" or "at" prefix before each command. Instead, it is only needed once at the beginning of the command line. Use a semicolon as command delimiter. The table below lists the AT commands you cannot enter together with other commands on the same line. Otherwise, the responses may not be in the expected order. AT command type Comment V.250 commands with FAX commands (Prefix AT+F) GSM 7.07 commands with Siemens commands, Prefix AT^S) GSM 7.05 commands (SMS) To be used standalone Commands starting with AT& To be used standalone AT+IPR To be used standalone Note: When concatenating AT commands please keep in mind that the sequence of processing may be different from the sequential order of command input. Therefore, if the consecutive order of the issued commands and the associated responses is your concern, avoid concatenating commands on the same line. MC55_ATC_V04.00 Confidential / Released Page 18 of 475 3/17/06 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. For example, the byte 0x36 (decimal 54) is displayed as "36" (two characters). IRA is used here for input 8-bit or 16-bit data via terminal devices using text mode. This means only characters 'A'..F','a'..'f' and '0'..'9' are valid. • Escape sequences The escape sequence used within a text coded in the GSM default alphabet (0x1B) must be correctly interpreted by the TE, both for character input and output. To the module, an escape sequence appears like any other byte received or sent. • Terminal Adapter (TA) TA is used equivalent to Mobile Equipment (ME) which stands for the GSM module described here. It uses GSM default alphabet as its character set. • Terminal Equipment (TE) TE is the device connected to the TA via serial interface. In most cases TE is an ANSI/ASCII terminal that does not fully support the GSM default alphabet, for example MS Hyperterminal. • TE Character Set The character set currently used by Terminal Equipment is selected with AT+CSCS. • Data Coding Scheme (dcs) DCS is part of a short message and is saved on the SIM. When writing a short message to the SIM in text mode, the dcs stored with AT+CSMP is used and determines the coded character set. The behavior when encountering characters, that are not valid characters of the supported alphabets, is undefined. Due to the constraints described below it is recommended to prefer the USC2 alphabet in any external application. If the GSM alphabet is selected all characters sent over the serial line (between TE and TA) are in the range from 0 to 127 (7 Bit range). CAUTION: ASCII alphabet (TE) is not GSM alphabet (TA/ME) ! Several problems resulting from the use of GSM alphabet with ASCII terminal equipment: • "@" character with GSM alphabet value 0 is not printable by an ASCII terminal program (e.g. Microsoft© Hyperterminal®). • "@" character with GSM alphabet value 0 will terminate any C string! This is because the 0 is defined as C string end tag. Therefore, the GSM Null character may cause problems on application level when using a 'C'function as "strlen()". This can be avoided if it is represented by an escape sequence as shown in the table below. By the way, this may be the reason why even network providers often replace "@"with "@=*" in their SIM application. • Other characters of the GSM alphabet are misinterpreted by an ASCII terminal program. For example, GSM "ö" (as in "Börse") is assumed to be "|" in ASCII, thus resulting in "B|rse". This is because both alphabets mean different characters with values hex. 7C or 00 and so on. • In addition, decimal 17 and 19 which are used as XON/XOFF control characters when software flow control is activated, are interpreted as normal characters in the GSM alphabet. When you write characters differently coded in ASCII and GSM (e.g. Ä, Ö, Ü), you need to enter escape sequences. Such a character is translated into the corresponding GSM character value and, when output later, the GSM character value can be presented. Any ASCII terminal then will show wrong responses. MC55_ATC_V04.00 Confidential / Released Page 19 of 475 3/17/06 Table 1.5: Examples for character definitions depending on alphabet GSM 03.38 character GSM character hex. value Corresponding ASCII character ASCII Esc sequence Hex Esc sequence Ö 5C \ \5C 5C 35 43 " 22 " \22 5C 32 32 ò 08 BSP \08 5C 30 38 @ 00 NULL \00 5C 30 30 CAUTION: Often, the editors of terminal programs do not recognize escape sequences. In this case, an escape sequence will be handled as normal characters. The most common workaround to this problem is to write a script which includes a decimal code instead of an escape sequence. This way you can write, for example, short messages which may contain differently coded characters. MC55_ATC_V04.00 Confidential / Released Page 20 of 475 3/17/06 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. (For related mapping definition see: http://www.unicode.org/Public/MAPPINGS/ETSI/GSM0338.TXT) Figure 1.1: Main character table of GSM 03.38 alphabet 1) This code is an escape to the following extension of the 7 bit default alphabet table. 2) This code is not a printable character and therefore not defined for the UCS2 alphabet. It shall be treated as the accompanying control character. MC55_ATC_V04.00 Confidential / Released Page 21 of 475 3/17/06 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) This code is defined as a Page Break character and may be used for example in compressed CBS messages. Any mobile which does not understand the 7 bit default alphabet table extension mechanism will treat this character as Line Feed. MC55_ATC_V04.00 Confidential / Released Page 22 of 475 3/17/06 In the event that an MS receives a code where a symbol is not represented in Figure 1.2, Extension character table of GSM 03.38 alphabet the MS shall display the character shown in the main default 7 bit alphabet table (see Figure 1.1, Main character table of GSM 03.38 alphabet). 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 internal (TA) and external (TE) character representation differ, i.e. if the Data Coding Scheme and the TE character use different coding. 1.5.2.1 Implementing output of SIM data to Terminal (direction TA to TE) Used character set DCS = 7 bit GSM DCS = 8 bit Data DCS = 16 bit UCS2 GSM Case 1 GSM (1:1) Case 2 8 bit to IRA (1:2) Case 3 UCS2 to IRA (2:4) Case 4 Case 5 GSM to IRA (1:4) 8 bit to IRA (1:4) Note: The ratio of SIM bytes to output bytes is given in parentheses. Case 6 UCS2 to IRA (2:4) UCS2 Case 1 Every GSM character is sent to the TE as it is (8-bit value with highest bit set to zero). Example: 47'H, 53'H, 4D'H → 47'H, 53'H, 4D'H, displayed as "GSM" Case 2 Every data byte is sent to the TE as 2 IRA characters each representing a halfbyte. Example: B8'H (184 decimal) → 42'H, 38'H, displayed as "B8" Case 3 Every 16-bit UCS2 value is sent to the TE as 4 IRA characters. Example: C4xA7'H (50343 decimal) → 43'H, 34'H, 41'H, 37'H, displayed as "C4A7" Problem: An odd number of bytes leads to an error because there are always two bytes needed for each USC2 character Case 4 Every GSM character is sent to the TE as 4 IRA characters to show UCS2 in text mode. Example: 41'H ("A") → 30'H, 30'H, 34'H, 31'H, displayed as "0041" Case 5 Every data byte is sent to the TE as IRA representation of UCS2 (similar to case 4). Example: B2'H → 30'H, 30'H, 42'H, 32'H, displayed as "00B2" Case 6 Every 16-bit value is sent to the TE as IRA representation of it. It is assumed that number of bytes is even. Example: C3x46'H → 43'H, 33'H, 34'H, 36'H, displayed as "C346" MC55_ATC_V04.00 Confidential / Released Page 23 of 475 3/17/06 1.5.2.2 Implementing input of Terminal data to SIM (direction TE to TA) Used character set DCS = 7 bit GSM DCS = 8 bit Data DCS = 16 bit UCS2 GSM Case 1 GSM (1:1) Case 2 IRA to 8 bit (2:1) Case 3 IRA to 16 bit (4:2) UCS2 Case 4 Case 5 Case 6 UCS2 to GSM (4:1) UCS2 to 8 bit (4:1) UCS2 to 16 bit (4:2) Note: The ratio between the number of input characters and bytes stored on the SIM is given in parentheses. Case 1 Every character is sent from TE to TA as GSM character (or ASCII with standard terminal emulation, e.g. Hyperterminal). Character value must be in range from 0 to 127 because of 7-bit GSM alphabet. To reach maximum SMS text length of 160 characters in 140 bytes space characters will be compressed on SIM. This must be set using the parameter <dcs> of AT+CSMP (add 64). Example: "ABCDEFGH" typed is sent and stored uncompressed as → 4142434445464748'H (stored compressed as 41E19058341E91'H) Case 2 Every data byte is sent as 2 IRA characters. Maximum text length is 280 IRA characters which will be converted into 140 bytes SMS binary user data Example: "C8" typed is sent as 43'H, 38'H → stored as C8'H Case 3 Every 16-bit value is sent as 4 IRA characters. Maximum text length is 280 IRA characters which will be convertedinto 70 UCS2 characters (16-bit each) Number of IRA characters must be a multiple of four because always 4 half bytes are needed for a 16-bit value Example: "D2C8" typed is sent as 44'H, 32'H, 43'H, 38'H → stored as D2C8'H Case 4 Every GSM character is sent as 4 IRA characters representing one UCS2 character. Example: To store text "ABC" using UCS2 character set you have to type "004100420043". This is sent as 30'H,30'H,34'H,31'H, 30'H,30'H,34'H,32'H, 30'H,30'H,34'H,33'H → detected as IRA representation of 3 UCS2 characters, converted to GSM character set and stored as 41'H, 42'H, 43'H. Maximum input is 640 IRA characters repesenting 160 UCS2 characters when compression is active. These are converted to 160 GSM 7-bit characters. Without compression only 140 GSM characters can be stored which are put in as 560 IRA characters. Values of UCS2 characters must be smaller than 80'H (128 decimal) to be valid GSM characters. Number of IRA characters must be a multiple of four. Problems: • "41" → Error, there are four IRA characters (two bytes) needed • "0000" → Error, not an UCS2 character • "4142" → Error, value of UCS2 character > 7F'H • "008B" → Error, value of UCS2 character > 7F'H This affects the maximum input length of a string) Case 5 Every UCS2 character is sent as 4 IRA characters and is converted into two 8-bit values. This means that the first two characters have to be '00'. Example: UCS2 character 009F'H typed as "009F" is sent as 30'H,30'H,39'H,46'H → converted into 8-bit value 9F'H. Maximum number of UCS2 characters is 140 which are represented by 560 IRA characters. Number of IRA characters must be a multiple of four. Case 6 Every UCS2 character is sent as 4 IRA characters each and is converted into a 16-bit value again. Example: UCS2 character 9F3A'H typed as "9F3A" is sent as 39'H,46'H,33'H,41'H → converted into 9F3A'H. Maximum number of UCS2 characters is 70 which are represented by 280 IRA characters. Number of IRA characters must be a multiple of four. Invalid UCS2 values must be prevented. MC55_ATC_V04.00 Confidential / Released Page 24 of 475 3/17/06 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. The High Watermark of the input/output buffer should be set to approximately 60% of the total buffer size. The Low Watermark is recommended to be about 30%. The data flow should be stopped when the capacity rises close to the High Watermark and resumed when it drops below the Low Watermark. The time required to cause stop and go results in a hysteresis between the High and Low Watermarks. During Multiplex mode (AT+CMUX) it is recommended to use hardware flow control. 1.6.1 Software Flow Control (XON/OFF Handshake) Software flow control sends different characters to stop (XOFF, decimal 19) and resume (XON, decimal 17) data flow. The only advantage of software flow control is that three wires would be sufficient on the serial interface. 1.6.2 Hardware Flow Control (RTS/CTS Handshake) Hardware flow control sets or resets the RTS/CTS wires. This approach is faster and more reliable, and therefore, the better choice. When the High Watermark is reached, CTS is set inactive until the transfer from the buffer has completed. When the Low Watermark is passed, CTS goes active again. To achieve smooth data flow, ensure that the RTS/CTS lines are present on your application platform. The application should include options to enable RTS/CTS handshake with the GSM engine. This needs to be done with the AT command AT\Q3 - it is not sufficient to set RTS/CTS handshake in the used Terminal program only. The default setting of the GSM engine is AT\Q0 (no flow control) which must be altered to AT\Q3 (RTS/CTS hardware handshake on). The setting is stored volatile and must be restored each time after the GSM engine was switched off. AT\Q has no read command. To verify the current setting of AT\Q, simply check the settings of the active profile with AT&V. Often, fax programs run an intialization procedure when started up. The intialization commonly includes enabling RTS/CTS hardware handshake, eliminating the need to set AT\Q3 once again. However, before setting up a CSD call, you are advised to check that RTS/CTS handshake is set. RTS/CTS hardware handshake must also be set if you want to take advantage of the CYCLIC SLEEP modes. For further details refer to AT+CFUN. Note: After deactivating the RTS line, the ME may still send up to 264 bytes (worst case). This can be easily handled if the buffer of the host application is sufficiently sized, and if a hysteresis is implemented regarding its Rx buffer. For host applications that are required to handle a large amount of data at high speed, a total buffer capacity of 512 bytes is recommended. MC55_ATC_V04.00 Confidential / Released Page 25 of 475 3/17/06 1.7 Unsolicited Result Code Presentation URC stands for Unsolicited Result Code and is a report message issued by the ME without being requested by the TE, i.e. a URC is issued automatically when a certain event occurs. Hence, a URC is not issued as part of the response related to an executed AT command. Typical events leading to URCs are incoming calls ("RING"), waiting calls, received short messages, changes in temperature, network registration etc. A list of all URCs can be found in Section 20.7, Summary of Unsolicited Result Codes (URC). To announce a pending URC transmission the ME will do the following: • The ME activates its RING line (logic "1") for 1 second, i.e. the RING line changes to the physical "Low" level. This allows the TE to stay in power saving mode until an ME related event requests service. If several URCs occur coincidently or in quick succession each URC triggers the RING line independently, although the line will not be deactivated between each URC. As a result, the RING line may stay low for more than 1 second. If an incoming call is answered within less than 1 second (with ATA or if autoanswering is set to ATS0=1) than the RING line will be deactivated earlier. The "^SHUTDOWN" URC will not activate the RING line. • If the AT command interface is busy a "BREAK" will be sent immediately but the URC will not be issued until the line is free. This may happen if the URC is pending in the following cases: - During the processing of an AT command (i.e. the time after the TE echoes back the first character "A" of an AT command just sent by itself until the ME responds with "OK" or "ERROR"). - During a data call. Please note that AT command settings may be necessary to enable in-band signaling, e.g. refer to AT+CMER or AT+CNMI. It is strongly recommended to use the multiplex mode to map logical communication channels onto the serial line of the MC55, for details refer to [5] and AT command AT+CMUX. Doing so it is possible to use one channel to still process URCs while having a data call active on another. 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 <text>", "^SHUTDOWN" and the Fax Class 2 URCs listed in Section 12.1, FAX parameters. If autobauding is enabled (as factory default mode or set with AT+IPR=0), URCs generated after restart will be output with 57600 bps until the ME has detected the current bit rate. The URCs "^SYSSTART", "^SYSSTART <text>", however, are not presented at all. For details please refer to Section 4.7.1, Autobauding. To avoid problems we recommend to configure a fixed bit rate rather than using autobauding. 1.7.1 Communication between Customer Application and MC55 Leaving hardware flow control unconsidered the Customer Application (TE) is coupled with the MC55 (ME) via a receive and a transmit line. Since both lines are driven by independent devices collisions may (and will) happen, i.e. while the TE issues an AT command the MC55 starts sending an URC. This will probably lead to the TE's misinterpretation of the URC being part of the AT command's response. To avoid this conflict the following measures must be taken: • • If an AT command is finished (with "OK" or "ERROR") the TE shall always wait at least 100 milliseconds before sending the next one. This gives the MC55 the opportunity to transmit pending URCs and get necessary service. Note that some AT commands may require more delay after "OK" or "ERROR" response, refer to the following command specifications for details. The TE shall communicate with the MC55 using activated echo (ATE1), i.e. the MC55 echoes characters received from the TE. Hence, when the TE receives the echo of the first character "A" of the AT command just sent by itself it has control both over the receive and the transmit paths.

The format of <err> can be either numeric or verbose and is selectable via AT+CMEE. A result error code terminates the execution of the command and prevents the execution of all remaining commands that may follow on the same command line. If so, neither "ERROR" nor "OK" result codes are returned for these commands. A 30 seconds timeout will deliver "ERROR" when the input of a command is not complete. Using the wrong command syntax may result in errors: For example, using the execute command syntax although the command has no execute format, causes "ERROR" to be returned. Likewise, using the write command syntax although the command has no write format causes "+CME ERROR: <err>" to be returned.

MC55_ATC_V04.00 Confidential / Released Page 36 of 475 3/17/06 2.8 AT+CFUN Set phone functionality The AT+CFUN command serves to control the functionality level of the 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. SLEEP mode falls in two categories: • NON-CYCLIC SLEEP mode <fun>=0 • and CYCLIC SLEEP modes, selectable as <fun>= 5, 6, 7, 8 or 9. NON-CYCLIC SLEEP mode permanently blocks the serial interface. The CYCLIC SLEEP mode, however, is a dynamic process which alternatingly enables and disables the serial interface. The major benefit of all CYCLIC SLEEP modes is that the serial interface remains accessible and that, in intermittent wake-up periods, characters can be sent or received without terminating the selected mode. The best choice is using <fun>= 7, 8 or 9, since in these modes MC55 automatically resumes power saving, after you have sent or received a short message or made a call. <fun>=5 or 6 do not offer this feature to the same extent and are only supported for compatibility with earlier releases. In all CYCLIC SLEEP modes, you can enter <fun>=1 to permanently wake up MC55 and take it back to full functionality. Please refer to Section 2.8.1, Wake up the ME from SLEEP mode for a summary of all SLEEP modes and the different ways of waking up the module. For CYCLIC SLEEP mode (<fun>= 5, 6, 7, 8 or 9) both the ME and the application must be configured to use hardware flow control. This is necessary since the CTS signal is set/reset every time when the ME listens to a paging message from the base station. This is the way how the module indicates to the application when the UART is active. For detailed information on the timing of the CTS signal refer to [2]. The default setting of hardware flow control is AT\Q0 which must be altered to AT\Q3. For use after restart you are advised to add it to the user profile saved with AT&W. If both interfaces ASC0 and ASC1 are connected, hardware flow control must be set in either application. The AT+CFUN test command returns the values of the supported parameters. The AT+CFUN read command returns the current functionality value. The AT+CFUN write command can be used to reset the ME, to choose one of the SLEEP modes or to return to full functionality.

Last ! 3/17/06 Unsolicited Result Codes URC 1 ^SYSSTART Indicates that the ME has been started and is ready to operate. If autobauding is active (AT+IPR=0) the URC is not generated. URC 2 ^SYSSTART CHARGE ONLY MODE Indicates that the ME has entered the CHARGE ONLY mode. This occurs if the charger is connected while the ME is in POWER DOWN mode. If autobauding is active (AT+IPR=0) the URC is not generated. In CHARGE ONLY mode the ME is neither registered to the GSM network nor are the serial interfaces fully accessible. Only the AT commands listed in Section 20.4, Availability of AT Commands Depending on Operating Mode of ME can be used. For further details on charging refer to the Hardware Interface Description [2]. Parameter Description <fun>(num) 0 NON-CYCLIC SLEEP mode: In this mode, the AT interface is not accessible. Consequently, after setting <fun>=0, do not send further characters. Otherwise these characters remain in the input buffer and may delay the output of an unsolicited result code. The first wake-up event stops power saving and takes the ME back to full functionality level <fun>=1. [1](&F)(P) Full functionality. If the ME is in one of the CYCLIC SLEEP modes you can issue AT+CFUN=1 to stop power saving and return to full functionality. Keep in mind that, unlike the reset command described below, this action does not restart the ME but only changes the level of functionality. See parameter <rst> for details on the reset. 5 CYCLIC SLEEP mode: In this mode, the serial interface is shortly enabled while CTS is active. If characters are recognized on the serial interface, the ME stays active for 2 seconds after the last character was sent or received. 6 CYCLIC SLEEP mode: In this mode, the serial interface is shortly enabled while CTS is active. If characters are recognized on the serial interface, the ME stays active for 10 minutes after the last character was sent or received. To ensure that power saving takes effect immediately, the ME stays active for only 2 seconds after <fun>=6 was entered. 7 CYCLIC SLEEP mode: In this mode, the serial interface is shortly enabled while CTS is active. If characters are recognized on the serial interface, the ME stays active for 2 seconds after the last character was sent or received. ME exits SLEEP mode only, if AT+CFUN=1 is entered. 8 CYCLIC SLEEP mode: In this mode, the serial interface is shortly enabled while CTS is active. If characters are recognized on the serial interface, the ME stays active for 10 minutes after the last character was sent or received. ME exits SLEEP mode only, if AT+CFUN=1 is entered. To ensure that power saving takes effect immediately, the ME stays active for only 2 seconds after <fun>=8 was entered. 9 CYCLIC SLEEP mode: In this mode, the serial interface is shortly enabled while CTS is active. If characters are recognized on the serial interface, the ME stays active after the last character was sent or received for at least the time, which can be configured MC55_ATC_V04.00 Confidential / Released Page 38 of 475 3/17/06 by AT^SCFG="PowerSaver/Mode9/Timeout",<psm9to> (temporary wakeup). In contrast to SLEEP modes 5,6,7 and 8 assertion of RTS can also be used to temporarily wake up the ME. In this case too, activity time is at least the time set with AT^SCFG="PowerSaver/Mode9/Timeout",<psm9to>. RTS can be activated either from ASC0 or ASC1. ME exits SLEEP mode only, if AT+CFUN=1 is entered. <rst>(num) The parameter can only be used if the serial interface is enabled. Due to the command syntax, you need to enter parameter <fun>, followed by <rst>, where <fun> is only a placeholder and has no effect. See examples below. [0] Placeholder for <fun> as stated above. 1 ME resets and restarts to full functionality. After reset and restart, PIN 1 authentication is necessary (AT+CPIN). If autobauding is enabled, it is recommended to wait 3 to 5 seconds before entering the first AT command. For details on autobauding refer to Section 4.7.1, Autobauding. Notes • If both serial interfaces ASC0 and ASC1 are connected, any functionality level set with AT+CFUN takes effect on both of them. In Multiplex mode, the CFUN profile is shared by all multiplexer channels. • If the ME is in Multiplexer mode, it is not recommended to activate SLEEP mode with AT+CFUN=<fun>. The best approach to properly control SLEEP mode in this case is to issue the PSC messages described in [5], Section "Power saving control". • When a circuit-switched call is in progress, <fun>=7 or 8 or 9 can be activated without terminating the call. However, setting <fun>=0, 5 or 6 during a circuit-switched call immediately disconnects this call. • Please keep in mind that power saving works properly only when PIN authentication has been done. If you attempt to activate power saving while the SIM card is not inserted or the PIN is not correctly entered, the selected <fun> level will be set, though power saving does not take effect. For the same reason, power saving cannot be used if MC55 operates in Alarm mode. Furthermore, in order to accept incoming calls, SMS or network related URCs in SLEEP mode the ME must be registered when it enters the SLEEP mode. • To check whether power saving is on, you can query the status with the read command AT+CFUN? only if the module is in full functionality mode or in CYCLIC SLEEP mode. If available, you can also take advantage of the status LED controlled by the SYNC pin (see AT^SSYNC and [2]). The LED remains "off" while the module is in any of the SLEEP modes. However, the module can wake up temporarily from power saving without leaving its CYCLIC SLEEP mode (without changing +CFUN "<fun>"), e.g. for a network scan after a loss of radio coverage, or after receipt of serial data during CYCLIC SLEEP mode. During this "temporary wakeup state" the LED will operate as if the ME was in full functionality mode. • Recommendation: In NON-CYCLIC SLEEP mode, you can set an RTC alarm to wake up the ME and return to full functionality. This is a useful approach because, in this mode, the AT interface is not accessible. Examples EXAMPLE 1 To check the level of functionality use the read command: AT+CFUN? +CFUN: 1 Default mode after ME was restarted Remember that the AT interface is not accessible in NON-CYCLIC SLEEP mode. Consequently, the read command is only useful when the ME is set to full functionality or, when <fun> is set to 5, 6, 7, 8 or 9. AT+CFUN? +CFUN: 5 CYCLIC SLEEP mode EXAMPLE 2 To set the ME to NON-CYCLIC SLEEP mode enter AT+CFUN=0 OK MC55_ATC_V04.00 Confidential / Released Page 39 of 475 3/17/06 When, for example, an SMS is being received and indicated by an unsolicited result code (URC), the ME wakes up to full operation. Note that the URC used in this example will appear only, if AT+CNMI=1,1 was configured before. +CMTI: "SM",5 After this, you may want to verify the operating status: AT+CFUN? +CFUN: 1 Indicates that ME has entered full functionality mode. EXAMPLE 3 To stop CYCLIC SLEEP mode and return to full functionality: AT+CFUN? +CFUN: 5 OK AT+CFUN=1 OK Remember that this approach is not applicable to the NON-CYCLIC SLEEP mode (since the serial interface is disabled). The NON-CYCLIC SLEEP mode ends with the first wake-up event. EXAMPLE 4 To reset and restart the ME: or alternatively, AT+CFUN=0,1 or 5,1 or 6,1 or 7,1 or 8,1 or 9,1 AT+CFUN=1,1 OK ^SYSSTART 2.8.1 The ^SYSSTART URC confirms that the ME has been rebooted. Note that ^SYSSTART appears only if AT+IPR ≠ 0. If the ME is in autobaud mode, it is recommended to wait 3 to 5 seconds before entering the first AT command. Remember to enter the SIM PIN after restart. Wake up the ME from SLEEP mode A wake-up event is any event that causes the ME to draw more current. Depending on the selected mode, the wake-up event either switches the SLEEP mode off and takes the ME back to full functionality AT+CFUN=1, or activates the ME temporarily without terminating the selected SLEEP mode. Definitions of the state transitions described in Table 2.3: • • • Quit: ME exits SLEEP mode.

It is possible to enable or disable this feature for all network operators, or to enable it for selected operators (max. 10). If the feature is enabled for all operators, any request to enable it for a specific operator will result in a "+CME ERROR: operation temporary not allowed". Changes of this parameter become active with the next call. Parameter is global for all interfaces, volatile and will not be reset by AT&F. "enabled"(P) AMR is used for every operator. "disabled" AMR is not used for any operator. 00000...999999 Enable AMR for the specified operator (in BCD or IRA format; see AT+COPS). <csv1>(str)(+CSCS) Call Speech Version1 This parameter can be used to query or configure the speech version 1 indication in the bearer capabilities in case of voice calls (see GSM 04.08). Speech version 2 (EFR) is always enabled; speech version 3 ( AMR) is not affected by this command. If you try to change this parameter as long as a circuit switched call is active, the command returns the new value and "OK", but the changes will not take effect before next call setup. Parameter is global for the ME, volatile and will not be reset by AT&F. "0"(P) FR and HR codecs are enabled for speech calls - full rate codec is preferred. "1" FR and HR codecs are enabled for speech calls - half rate codec is preferred.

Parameter is local for the interface, volatile and will not be reset by AT&F. "on" If the ME is in power saving mode 7 or 8 or 9 (see AT+CFUN) and hardware flow control is in use (AT\Q3) and the RTS line is inactive and there are incoming IP packets for a GPRS context which is online, then the RING line will be activated once, for a time which is configured by the parameter "URC/Ringline/ ActiveTime" (<urat>). The RING line to be used can be configured with the parameter "URC/Ringline" (<uri>). "off"(P) RING line is not activated for incoming IP packets. MC55_ATC_V04.00 Confidential / Released Page 54 of 475 3/17/06 <psm9to>(str)(+CSCS) Power saving mode 9 timeout This parameter can be used to query or configure the wake up time for power saving mode 9 (see AT+CFUN with parameter <fun>=9). Parameter is global for the ME, volatile and will not be reset by AT&F. 5...20(P)...36000 The granularity of the timeout value is 100ms (i.e. a value of 10 equal 1 second). The minimum timeout value that can be applied is 5, but accuracy is only guaranteed for timeout values greater than 20. <HandOverStatus>(str)(+CSCS) Call Handover Status This parameter offers a workaround to prevent problems during call handover into the 1900 MHz (or 1800 MHz) band, caused by non-conforming configurations of the 1900 MHz (or 1800 MHz) GSM network. "0"(P) Disable workaround. "1" Enable workaround. This value should be selected when handover into a 1900 MHz (or 1800 MHz) GSM network fails. If required for permanent use the value needs to be set each time the ME is restarted. <tcpIrt>(str)(+CSCS) Initial Retransmission Timeout (IRT) 1...3(&F)(D)...60 This parameter determines the time (in seconds) the TCP/IP stack will wait before starting the first retransmission of packets during the initial connection establishment phase. The TCP protocol ensures the retransmission of packets several times at increasing intervals until some upper limit is reached. This mechanism prevents packet loss and serious congestion problems. In addition, the parameters <tcpMr> and <tcpOt> can be set to further optimize this mechanism for special conditions depending on the mobile network. Parameter is global for the ME and non-volatile. Use of default value is recommended. If changed the new value takes effect the next time you start an Internet service with AT^SISO. <tcpMr>(str)(+CSCS) Maximum Number of Retransmissions (MR) 1...10(&F)(D)...30 This parameter determines the maximum number of times to retransmit TCP packets. The value set with <tcpMr> will be assumed as default for the <srvParmTag> "tcpMR" when a new service profile is created with AT^SISS. In each service profile, you can set another "tcpMR" value which has precedence over the global value set with AT^SCFG. Existing service profiles are not affected when you change the global value via AT^SCFG. Parameter is global for the ME and non-volatile.

Setting the maximum value is practically equivalent to deactivating the tcpOT mechanism because the maximum time would never be reached by the TCP/ IP stack. The value set with <tcpOt> will be assumed as default for the <srvParmTag> "tcpOT" when a new service profile is created with AT^SISS. HowPage 55 of 475 3/17/06 ever, in each service profile, you can set another "tcpOT" value which has precedence over the global value set with AT^SCFG.

"^SIS" URCs with <urcCause>=1 or 2 used to indicate incoming Socket connections are always enabled. Parameter is global for the ME and non-volatile. "on"(&F)(D) Enable URCs related to Internet service commands. Throughout the Chapter "Internet Service AT Commands" the mode is also referred to as URC mode. "off" Disable URCs related to Internet service commands. This requires the host application to employ polling techniques when using the Internet service AT commands: The host application is responsible to retrieve all status information needed to control an Internet session. The method is referred to as polling mode. <succ>(str)(+CSCS) CIEV Call Status Indication This parameter can be used to control the behaviour of URC "+CIEV: call".

Status Control Commands The AT Commands described in this chapter allow the external application to obtain various status information from the MC55. 3.1 AT+CMER Mobile Equipment Event Reporting This command controls details of the "+CIEV" URC presentation related to AT^SIND and AT+CIND. If registered via these commands the URCs are sent whenever a value of the related indicator changes. In addition, AT+CMER controls "^SLCC" URCs related to AT^SLCC. For details refer to Call Status Information, AT^SLCC and AT^SCFG, parameter <sucs>. The read command returns the URC presentation mode <mode> and among others, the indicator event reporting status <ind>. The write command enables and disables the presentation of "+CIEV: <indDescr>, <indValue>1[, <indValue>2]" URCs. <indDescr> refers to the name of a "+CIEV" indicator and <indValue> is the new value of this indicator. After AT+CMER has been switched on, URCs for all registered indicators will be issued. See examples provided in Section 3.2, AT+CIND and Section 3.3, AT^SIND. Syntax Test Command AT+CMER=?

Note • If the ME operates on different instances (MUX channels 1, 2, 3 or ASC0/ASC1) avoid different settings for routing and indicating SMS. For example, if messages shall be routed directly to one instance of the TE (set with AT+CNMI, AT^SSDA), it is not possible to activate the presentation of URCs with AT+CMER or AT+CNMI on another instance. Any attempt to activate settings that conflict with existing settings on another interface, will result in CME ERROR, or accordingly CMS ERROR. MC55_ATC_V04.00 Confidential / Released Page 61 of 475 3/17/06 3.2 AT+CIND Indicator control The AT+CIND command controls the presentation of Indicator Event Reports related to various functions such as battery charge level, signal quality, service availability, sound generation, indication of unread short messages, full SMS storage, call in progress or roaming activities. Use of AT+CIND has become outdated. Rather we recommend the more powerful AT^SIND command which is easier to use and provides additional indicators. All indicators provided by AT+CIND can be handled with AT^SIND as well. AT+CIND supports two ways to get the values related to indicators: • One approach is to query the current status of each indicator by using the read command AT+CIND?. It returns the status no matter whether the indicator has been registered with the write command AT+CIND=[<mode>[,<mode>[,...]]]. • The other way is an event-driven notification based on the "+CIEV" URCs. In this case, the ME will automatically send a message to the application, whenever the value of an indicator changes. The application should be designed to react adequately when receiving a URC. The presentation of these URCs depends on two settings: - The indicators must be registered with the write command AT+CIND=[<mode>[,<mode>[,...]]]. When the ME is switched on all of them are in registered mode. Any indicator can be excluded if deregistered with <mode>=0. To register or deregister an indicator the AT+CIND write command requires to type the value <mode>=1 or 0 exactly at the position where the indicator is located in the list. This is not necessary with AT^SIND which allows to specify indicators by name. See examples below. - The presentation of the registered indicators must be enabled with AT+CMER.

More indications are available via AT^SIND. Therefore use of AT^SIND for control of all indications is recommended. The following indications are accessible via AT+CIND: "battchg" Battery charge level 0..4 or 5 if no measuring is performed, e.g because no battery is connected. Also refer to AT^SBC. "signal" Signal quality (0..7) or (99) if not measurable The indicated value is the bit error rate of the signal received. Bit errors are estimated values. See also AT+CSQ. "service" Service availability (0-1) 0: Not registered to any network 1: Registered to home network or, if "roam"=1 then registered to another network "sounder" Sounder activity (0-1) Reports every event that causes the ME to generate a tone. Value 1 means for example: Incoming call - ME is ringing. Note that the URC "+CIEV: sounder" will be output only if ringing tones are activated with AT^SRTC. Waiting call - ME generates waiting call tone (if call waiting is enabled). Outgoing call - ME generates Call Progress tone. Outgoing call - ME generates BUSY tone. The value changes to 0 when the tone stops. "message" Unread short message at memory location <mem1> (0-1); refer to AT+CPMS "call" Call in progress (0-1). Indicator value is "1" if at least one call is in state "active" or "held". Depending on the parameter <succ> selected with AT^SCFG the indicator "call" will be issued • when a state transition ends in state "active" or state "unknown", if <succ>="restricted", • when any state transition (including transitions beginning or ending in state "unknown") occurs in the list of active calls or when a traffic channel is established, if <succ>="verbose". Also refer to Section 7.1, Call Status Information. "roam" Roaming indicator (0-1) 0: Registered to home network or not registered 1: Registered to other network "smsfull" A short message memory storage in the MT has become full (1) or memory locations are available (0), i.e. range is (0-1) "rssi" Received signal (field) strength (0..5) or (99) if not measurable 0: signal strength <= -112 dbm 1-4: signal strength in 15 dbm steps 5: signal strength >= -51 dbm Received signal (field) strength can also be obtained with AT+CSQ. However, the signal strength is scaled to value range 0..31 by this command. <mode>(num) 0 Indicator is deregistered. The indicator will not be presented as "+CIEV" URC, but can be queried with AT+CIND?. [1](&F)(P) Indicator is registered, indicator event report allowed. MC55_ATC_V04.00 Confidential / Released Page 63 of 475 3/17/06 Notes • Due to its restrictive value range, indicator "call" does not clearly reflect specific call states (such as alerting, active, held etc.), but rather serves to trigger the application to retrieve the new call status from the list of current calls with the AT commands AT^SLCC, AT+CLCC or AT^SCNI. • If AT^SCFG setting <succ>="verbose", indicator "call" will be issued also when a traffic channel is established, or when a call enters states "terminating" or "dropped" (see Call Status Information). In these cases, the relevant information about the cause of the display is available only from AT command AT^SLCC.

All indicators supported by AT+CIND are accessible with this command, too. A detailed description of these indicators can be found there. The following indicators are accessible via AT^SIND only: "audio" Activity of the built-in audio unit. 0 Audio unit not active. 1 Value 1 means for example: Outgoing voice call: Indicator appears when dialing starts. Incoming voice call: Indicator appears prior to the RING result code. "vmwait1" Voice Message Waiting Indication for line 1 0 The value 0 notifies that no new voice message is available, and is provided by the service center to clear the voice message indication after the subscriber has retrieved all voice messages. 1 The value 1 notifies the subscriber that the mailbox contains one or several messages. "vmwait1" and "vmwait2" indicate the receipt of a special short message with a Voice Message Waiting Indicator. The service must be provisioned by the operator. The numbers 1 or 2 in "vmwait1" and "vmwait2" are related to the two lines of the Alternate Line Service (ALS), also defined in CPHS Phase 2 standard. For further details refer to the AT^SALS command. The presentation mode of the indicator varies with the operator: If more than one message are waiting, some operators only indicate the first one, others deliver the indicator each time a new voice message is put into the mailbox. After the subscriber has retrieved all voice messages the service center automatically sends another message indication which provides the value 0. Some operators may also send the number of waiting voice messages along with the indication. In this case, the number will be displayed by the MC55 as part of the URC. For example, "+CIEV: vmwait1,1,5" notifies that five new voice messages are waiting. However, it should be noted that neither the read command AT^SIND? nor the write command AT^SIND=<mode>,2 display the number of waiting messages. MC55_ATC_V04.00 Confidential / Released Page 66 of 475 3/17/06 The "vmwait" indicators do not apply if a network provider signals new voice mail(s) via standard SMS. In this case the indicator "message" will be displayed (see AT+CIND). "vmwait2" Voice Message Waiting Indication for line 2 0 See description of "vmwait1". 1 See description of "vmwait1". "ciphcall" Ciphering Status Change Indication 0 Current call or SMS is not ciphered. 1 Current call or SMS is ciphered. As stated in GSM specifications 02.07 and 02.09 the ciphering indicator feature allows the MC55 to detect that ciphering is not switched on and to indicate this to the user. The ciphering indicator feature may be disabled by the home network operator setting data in the "administrative data" field (EFAD) in the SIM, as defined in GSM 11.11. If this feature is not disabled by the SIM, then whenever a connection is in place, which is, or becomes unenciphered, an indication shall be given to the user. This enables the user's decision how to proceed. Read command returns valid ciphering status only if a call is in progress or active. If EFAD setting disables the ciphering indicator feature read command always indicates a ciphered link and no URC presentaion will take place. The following restrictions apply if the same serial channel is used for AT^SIND "ciphcall" indication and for the action triggering this URC. In general, the recommended solution is to use a dedicated channel for all status signalling via URCs. "eons" MC55_ATC_V04.00 Confidential / Released • If an unciphered mobile originated SMS is performed, AT^SIND "ciphcall" URCs on the same serial channel will be issued after the related "OK" and indicate the ciphering state at this time. Because the SMS is already sent at this time, two URCs will be issued on this channel, but both are indicating that ciphering is enabled. • If an unciphered mobile originated data call is performed, AT^SIND "ciphcall" URCs on the same serial channel will be issued after the interface is not longer blocked by the call (call is released or temporarily stopped) and indicate the ciphering state at this time. Enhanced Operator Name String (EONS) Indication The Enhanced Operator Name String indicator feature allows the MC55 to output various operator names for different PLMN identities via URC. It also allows the output of a different operator name based on a subset of the registered network by using a range of Location Area Codes (LACs) or a single LAC. The presentation of the "eons" indicator is determined by network activity. For example, the indicator appears every time a location update occurs or a NITZ information is sent, no matter whether or not the status of the EONS information has changed. This means that the same EONS information may be reported several times. The EONS tables are stored in the SIM card and will be read at power-up. Following are the SIM Elementary Files that are affected by the introduction of EONS feature in the SIM card: EFSST (SIM Service Table) - describes which features are active. EFOPL (Operator PLMN List) - contains the PLMN identification and location ID together with the index of the corresponding PNN record EFPNN (PLMN Network Name) - contains the full and short form version of the network name for the registered PLMN If the Operator Name Source is CPHS Operator Name String long and short form, refer to <indValue>, the following two SIM Elementary Files will be used: Page 67 of 475 3/17/06 EFONString (Operator Name String) - contains the name of the PLMN operator who issued the SIM. EFOPShort (Operator Name Short form) - contains a short form of the name of the PLMN operator who issued the SIM. "nitz" Network Identity and Time Zone indication This indicator shows the time relevant information elements of an MM Information (MMI) or GMM Information (GMMI) message received from the network (see GSM 24.008, ch. 9.2.15a and 9.4.19). The network usually sends a NITZ indicator when the mobile attaches to the network, when it enters a location area with different time zone or when a daylight change occurs. A NITZ indicator may consist of the following parameters: Universal Time (UT), local Time Zone (TZ), Daylight Saving Time (DST). All information elements of MMI/GMMI are optional and therefore, the presentation of the parameters <nitzUT>, <nitzTZ>, <nitzDST> varies with the network. For example, the network may send all three parameters UT, TZ, DST, or only UT and TZ or only TZ. UT is indicated in usual date/time format and represents the current world time (GMT) at the moment when sent. TZ is given as a positive (east) or negative (west) offset from UT in units of 15 minutes. DST shows the number of hours added to the local TZ because of daylight saving time (summertime) adjustment. Usually DST is 1 hour but it can be also 2 hours in certain locations. Example for time and time zone with DST: +CIEV: nitz,"04/07/23,13:39:20",-28,1 In this example TZ is -28, showing a time offset of -7 hours (west) to Universal Time/GMT (which never changes for DST). DST is 1 which indicates that one hour was added to TZ because of Daylight Saving Time. If a network does not send the DST parameter the TZ value would be -32 (8 hours west) as would be done in winter: +CIEV: nitz,"04/11/23,13:39:20",-32 Please be aware that despite the last NITZ value can be looked up again via "AT^SIND=nitz,2" the returned values may be out of date. Especially the UT value is obsolete because there is no internal NITZ clock and therefore no continuation of UT. NITZ values are lost when the module detaches from network. Also when a manual network selection fails and the module automatically falls back to the previous network the NITZ values cannot be recalled. Nevertheless an indicated time zone is valid until a new MMI/GMMI will trigger another NITZ indication. <indValue>(num) Integer type value in the range stated above for the corresponding <indDescr>. Notes specific to the EONS feature: If the indicator is "eons", the <indValue> is a type associated to the operator name according to GSM 22.101 [23]. This type depends on the source of the operator name. Priority of types associated to the operator names is defined as follows (the type listed first has the highest priority). If a type cannot be indicated the next one will be used. 0 Not registered. 1 EF-OPL and EF-PNN (alphanumeric format, can contain up to 24 characters.) 2 Operator Name String in long and short format according to Common PCN Handset Specification (CPHS) [24] (alphanumeric format, can contain up to 16 characters). 3 Name information received by the NITZ service long and short form (alphanumeric format, can contain up to 16 characters). The short form will be displayed only if EFOPShort from CPHS is available.

Command Description The test command returns the values of the supported automatically detectable bit rates and the values of the supported fixed bit rates. The read command returns the current bit rate of the interface. The write command specifies the bit rate to be used for the interface. When you set a fixed-rate, make sure that both TE (DTE) and TA (DCE) are configured to the same rate. When you select autobauding, the TA will automatically recognize the bit rate currently used by the TE. The setting is stored in the non-volatile memory and will be used whenever the engine is powered up again. However, in case of autobaud mode (AT+IPR=0) the detected TA bit rate will not be saved and, therefore, needs to be resynchronized after restarting the GSM engine (see Section 4.7.1, Autobauding). Parameter Description <rate>(num)(&V) bit rate per second (bps) 0 Activates autobauding. Not supported on ASC1. See Section 4.7.1, Autobauding for further details. 300 600 1200 2400 4800 9600 MC55_ATC_V04.00 Confidential / Released Page 92 of 475 3/17/06 14400 19200 28800 38400 57600 115200 230400 Notes • Delivery value for <rate> is autobauding enabled (AT+IPR=0) on ASC0 and 57600bps on ASC1. It will not be restored with AT&F. • The current setting of AT+IPR will be preserved when you download firmware (i.e. a firmware update does not restore the factory setting) or in the event of power failure. • Generally, AT+IPR should be used as a standalone command. If nethertheless combinations with other commands on the same command line cannot be avoided, there are several constraints to be considered: - Avoid combinations with the AT commands listed in Section 1.4.2, Combining AT commands on the same command line. - Take into account, that a pause of 100ms is required between the response to the last command (e.g. OK) and the next command. - When you enter AT+IPR=0, autobauding will be activated after the response to the last command is received. - When local echo is active (ATE1) and you enter AT+IPR=x with other commands you may encounter the following problem: if switching to the new bit rate takes effect while a response is being transmitted, the last bytes may be sent with the new bit rate and thus, not properly transmitted. The following commands will be correctly sent at the new bit rate. • In order to account for greater amounts of data it is recommended to choose a minimum bit rate of 2400 bps. If the ME shall be operated in Multiplex mode we suggest a minimum bit rate of 4800bps. • In Multiplex mode, the write command AT+IPR=<rate> will not change the bit rate currently used, but the new bit rate will be stored and becomes active, when the module is restarted. • A selected bit rate takes effect after the write commands returns OK. 4.7.1 Autobauding To take advantage of autobaud mode specific attention must be paid to the following requirements: • Synchronization between TE and TA Ensure that TE and TA are correctly synchronized and the bit rate used by the TE is detected by the TA. To allow the bit rate to be synchronized simply use an "AT" or "at" string. This is necessary - after you have activated autobauding - when you start up the GSM engine while autobauding is enabled. It is recommended to wait 3 to 5 seconds before sending the first AT character. Otherwise undefined characters might be returned. If you want to use autobauding and autoanswer at the same time, you can easily enable the TE-TA synchronization, when you activate autobauding first and then configure the autoanswer mode (ATS0 ≠ 0). • Restrictions on autobauding operation - The serial interface shall be used with 8 data bits, no parity and 1 stop bit (factory setting), e.g. 2 stop bits are not supported for autobaud mode. - The command A/ cannot be used. - Only the strings "AT" or "at" can be detected (neither "At" nor "aT"). - URCs that may be issued before the ME detects a new bit rate (by receiving the first AT character) will be sent at the previously detected bit rate or, after ME restart, at 57600 bps. MC55_ATC_V04.00 Confidential / Released Page 93 of 475 3/17/06 - • It is not recommended to switch to autobauding from a bit rate that cannot be detected by the autobaud mechanism (e.g. 300 bps). Responses to AT+IPR=0 and any commands on the same line might be corrupted. Autobauding and bit rate after restart The most recently detected bit rate is stored when the ME is powered down (with AT^SMSO). Therefore, each time the module is restarted the correct bit rate must be found as described above. Unless the bit rate is determined, the following constraints apply: - An incoming CSD call or a network initiated GPRS request cannot be accepted. This must be taken into account when autobauding and autoanswer mode (ATS0 ≠ 0) are enabled at the same time, escpecially if SIM PIN 1 authentication is done automatically and the setting ATS0 ≠ 0 is stored to the user profile with AT&W. - Until the bit rate is found, URCs generated after restart will be output at 57600 bps. This applies only to user defined URCs, such as "+CREG", "CCWA", "^SCKS" etc. The URCs "^SYSSTART", "^SYSSTART CHARGE-ONLY MODE" and "^SYSSTART ALARM MODE" will not be indicated when autobauding is enabled. Note: To avoid any problems caused by undetermined bit rates in the direction from TA to TE we strongly recommend to configure a fixed bit rate rather than autobauding. • Autobauding and multiplex mode If autobauding is active you cannot switch to multiplex mode (see AT+CMUX). MC55_ATC_V04.00 Confidential / Released Page 94 of 475 3/17/06 4.8 AT+CMUX Enter multiplex mode All information provided in this section applies to the ASC0 interface only. The second interface ASC1 has no support of Multiplex mode. Multiplex mode according to the ETSI TS 101 669 and GSM 07.10 enables one physical serial asynchronous interface to be partitioned into three virtual channels. This allows you to take advantage of up to 3 simultaneous sessions running on the serial interface. For example, you can send or receive data or make a call on the first channel, while the other two channels are free to control the module with AT commands. The MC55 module incorporates an internal multiplexer and thus integrates all the functions needed to implement full-featured multiplex solutions. For the application on top, customers have the flexibility to create their own multiplex programs conforming to the multiplexer protocol. To help system integrators save the time and expense of designing multiplexer applications, SIEMENS AG offers WinMUX2k, a ready-to-use multiplex driver for Windows 2000 and Windows XP. Another approach is to develop customized solutions based on the sources of the WinMux2k driver. Refer to [5] which provides a detailed description of the multiplex architecture and step-by-step instructions of how to install and configure the multiplex mode. The WinMUX2k driver and its source files can be supplied on request. Please contact your local distributor to obtain the latest installation software and user's guide. Syntax Test Command AT+CMUX=?

The setup of the logical channels is initiated by the TE, i.e. the TE acts as initiator. This means that the TE shall ensure that logical channels are established before any further actions on the channels can be started. • There is a timeout of five seconds, if the multiplexer protocol is enabled and no multiplexer control channel is established. The GSM engine returns to AT command mode. • The parameter maximum frame size (N1) of AT+CMUX in GSM 07.10 is fixed to 98 bytes and cannot be changed. All other parameters are not available. 4.8.1 Restrictions on Multiplex mode When the serial interface ASC0 is in multiplex mode, data and fax calls can only be set up on logical channel 1. Due to this restriction, AT commands have a different behavior on channels 2+3 compared to channel 1. Several commands are not available, others return different responses. This section summarizes the concerned commands. For general rules and restrictions to be considered in Multiplex mode please refer to [5].

You can change S0,S3,S4,S5,S6,S7,S8,S10 and S18 using the related ATSn commands (see starting from ATS0). The other registers are read-only and for internal use only! 2) The applicability of the +++ escape sequence depends on the customer's external application based on the Mulitplexer Protocol. Recommendations for implementing an appropriate modem status command (MSC) are provided in [5], Section "Escape Sequence". 3) PDP contexts can be defined on any channel, but are visible and usable only on the channel on which they are defined (thus it is not possible to define a context on channel 2 and activate it on channel 3). GPRS connections can be established on two channels at a time. MC55_ATC_V04.00 Confidential / Released Page 96 of 475 3/17/06 Table 4.2: Summary of AT commands with Different Behavior in Multiplex Mode Command Description AT\Q It is recommended to use hardware flow control (AT\Q3). XON/XOFF flow control (AT\Q1) is not supported in Multiplex mode. See note regarding AT\Qn settings stored with AT&W if Multiplex mode is active. AT&V Different default configurations on channels 1, 2 and 3. AT&W Different user profiles can be stored on each channel. AT+IPR Before you start Multiplex mode, it is recommended to set the ME to 57600 bps (minimum should be 4800 bps). For GPRS we suggest to use 115200 bps or 230400 bps. In Multiplex mode, the write command AT+IPR=<rate> will not change the bit rate currently used, but the new bit rate will be stored and becomes active, when the module is restarted. AT+IPR=0 Multiplex mode cannot be activated while autobauding is enabled. AT+CALA On each channel an individual <text> message can be stored. but only one time setting applies to all channels. This means an alarm <time> set on one of the channels overwrites the time setting on all remaining channels. Therefore, the total number of alarm events returned by the read command AT+CALA? will always be <n>=0, no matter whether individual text messages are stored. When the alarm is timed out and executed the ME sends the URC only on the channel where the most recent alarm setting was made. The alarm time will be reset to "00/01/01,00:00:00" on all channels. AT+CMEE Presentation mode can be separately configured for each channel. AT+CNMA If Multiplex mode is activated the +CNMI parameter will be set to zero on all channels, if one channel fails to acknowledge an incoming message within the required time. AT+CNMI Phase 2+ parameters can only be used on one channel. The parameter for <mt> and <ds> on the other channels have to be set to zero. If either a SM or a Status Report is not acknowledged, all +CNMI parameter will be set to zero on all channels. AT+CFUN If the ME is in Multiplexer mode, it is not recommended to activate SLEEP mode with AT+CFUN=<fun>. The best approach to properly control SLEEP mode in this case is to issue the PSC messages described in [5], Section "Power saving control (PSC)". AT+CPMS Parameter <mem3> will be the same on all instances, but the settings of <mem1> and <mem2> may vary on each instance. AT^SSDA If one instance is set to <da>=1 and <mt>=1, then all other instances must be configured for <mt>=0. MC55_ATC_V04.00 Confidential / Released Page 97 of 475 3/17/06 4.8.2 Second serial interface ASC1 The second serial interface ASC1 is intended as an auxiliary interface for applications which need multiple parallel access to the module (e.g. to query status information during a data call), but cannot use the GSM 07.10 multiplexing protocol. Therefore this interface offers limited functionality only. • • • • • • No DTR, DSR, DCD, RING signals. These hardware lines do not exist. As a result, AT commands controlling the behavior of these lines (AT&D, AT&C, AT&S) are not allowed and return ERROR. No presentation of ^SYSSTART URCs on ASC1. After restart or reset of the ME, either check that the URC has been sent on ASC0 or wait approximately 3 seconds before entering the first AT command on ASC1. No Autobauding. The hardware is not capable of automatically detecting the baudrate on this interface, so the AT command which selects autobauding (AT+IPR=0) is not allowed and returns ERROR. No CSD calls, so all related AT commands cannot be used and return ERROR. No fax calls, so all AT+F commands cannot be used and return ERROR. No GSM 07.10 Multiplexer. If issued on the second interface AT+CMUX=0 returns ERROR. ASC1 is disabled when the multiplexer is enabled on the first serial interface ASC0. Yet, both ASC1 and the multiplexer channel 2 are using the same parameters, and thus, the same user defined profile (if any). As a result, a user profile stored on multiplexer channel 2 takes effect on ASC1 after closing the multiplexer and starting up ASC1. Likewise, a user profile stored on ASC1 will be loaded on multiplexer channel 2. This may be a problem when ASC1 is not connected, but flow control (for example AT\Q1 or AT\Q3) is stored to the user profile on the multiplexer channel 2. In this case, flow control takes effect on ASC1, when the multiplexer is switched off. If then for example a large amount of URCs is generated, their transmission might be stopped due to the flow control. To avoid this problem we recommend that you do not activate flow control on multiplexer channel 2 when you set up a user profile with AT&W. MC55_ATC_V04.00 Confidential / Released Page 98 of 475 3/17/06 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 AT+CPIN controls network authentication of the MC55. The read command returns an alphanumeric string indicating whether or not network authentication is required. The write command allows the MC55 to store the entered password. This may be for example the SIM PIN1 to register to the GSM network, or the SIM PUK1 to replace a disabled SIM PIN1 with a new one, or the PH-SIM PIN if the client has taken precautions for preventing damage in the event of loss or theft etc. If no PIN1 request is pending (for example if PIN1 authentication has been done and the same PIN1 is entered again) MC55 responds "+CME ERROR: operation not allowed"; no further action is required. Each time a password is entered with AT+CPIN the module starts reading data from the SIM. The duration of reading varies with the SIM card. This may cause a delay of several seconds before all commands which need access to SIM data are effective. See Section 20.1, Restricted access to SIM data after SIM PIN authentication for further detail. Syntax Test Command AT+CPIN=? Response(s) OK Read Command AT+CPIN?

No further entry needed. SIM PIN ME is waiting for SIM PIN1. SIM PUK ME is waiting for SIM PUK1 if PIN1 was disabled after three failed attempts to enter PIN1. SIM PIN2 ME is waiting for PIN2. This is only applicable when an attempt to access a PIN2 related feature was acknowledged with +CME ERROR: 17 ("SIM PIN2 required"), for example when the client attempts to edit the FD phonebook). In this case the read command AT+CPIN? also prompts for SIM PIN2. Normally, the AT+CPIN2 command is intended for SIM PIN2. SIM PUK2 ME is waiting for PUK2 to unblock a disabled PIN2. As above, this is only necessary when the preceding command was acknowledged with +CME ERROR: 18 ("SIM PUK2 required") and only if the read command AT+CPIN? also prompts for SIM PUK2. Normally, the AT+CPIN2 command is intended for SIM PUK2. Phone security locks set by client or factory PH-SIM PIN ME is waiting for phone-to-SIM card password if "PS" lock is active and the client inserts other SIM card than the one used for the lock. ("PS" lock is also referred to as phone or antitheft lock). PH-SIM PUK ME is waiting for Master Phone Code, if the above "PS" lock password was incorrectly entered three times. PH-FSIM PIN ME is waiting for phone-to-very-first-SIM card. Necessary when "PF" lock was set. When powered up the first time, ME locks itself to the first SIM card put into the card holder. As a result, operation of the mobile is restricted to this one SIM card (unless the PH-FSIM PUK is used as described below). PH-FSIM PUK ME is waiting for phone-to-very-first-SIM card unblocking password to be given. Necessary when "PF" lock is active and other than first SIM card is inserted. PH-NET PUK ME is waiting for network personalisation unblocking password PH-NS PIN ME is waiting for network subset personalisation password PH-NS PUK ME is waiting for network subset unblocking password PH-SP PIN ME is waiting for service provider personalisation password PH-SP PUK ME is waiting for service provider personalisation unblocking password PH-C PIN ME is waiting for corporate personalisation password PH-C PUK ME is waiting for corprorate personalisation un-blocking password MC55_ATC_V04.00 Confidential / Released Page 100 of 475 3/17/06 Notes • Successful PIN authentication only confirms that the entered PIN was recognized and correct. The output of the result code OK does not necessarily imply that the mobile is registered to the desired network. Typical example: PIN was entered and accepted with OK, but the ME fails to register to the network. This may be due to missing network coverage, denied network access with currently used SIM card, no valid roaming agreement between home network and currently available operators etc. MC55 offers various options to verify the present status of network registration: For example, the AT+COPS command indicates the currently used network. With AT+CREG you can also check the current status and activate an unsolicited result code which appears whenever the status of the network registration changes (e.g. when the ME is powered up, or when the network cell changes). • <pin> and <new pin> can also be entered in quotation marks (e.g. "1234"). • To check the number of remaining attempts to enter the passwords use the AT^SPIC command. • See AT+CPWD and AT^SPWD for information on passwords. • See AT+CLCK and AT^SLCK for information on lock types. 5.1.1 What to do if PIN or password authentication fails? PIN1 / PUK1: After three failures to enter PIN 1, the SIM card is blocked (except for emergency calls). +CME ERROR: 12 will prompt the client to unblock the SIM card by entering the associated PUK (= PIN Unblocking Key / Personal Unblocking Key). After ten failed attempts to enter the PUK, the SIM card will be invalidated and no longer operable. In such a case, the card needs to be replaced. PIN1 consists of 4 to 8 digits, PUK1 is an 8-digit code only. To unblock a disabled PIN1 you have two options: • • You can enter AT+CPIN=PUK1,new PIN1. You can use the ATD command followed by the GSM code **05*PUK*newPIN*newPIN#;. PIN2 / PUK2: PIN2 prevents unauthorized access to the features listed in AT+CPIN2. The handling of PIN2 varies with the provider. PIN2 may either be a specific code supplied along with an associated PUK2, or a default code such as 0000. In either case, the client is advised to replace it with an individual code. Incorrect input of PUK2 will permanently block the additional features subject to PIN2 authentification, but usually has no effect on PIN1. PIN2 consists of 4 digits, PUK2 is an 8-digit code only. To unblock a disabled PIN2 you have two options: • • You can enter AT+CPIN2=PUK2,new PIN2. You can use the ATD command followed by the GSM code **052*PUK2*newPIN2*newPIN2#;. Phone lock: If the mobile was locked to a specific SIM card (= "PS" lock or phone lock), the PUK that came with the SIM card cannot be used to remove the lock. After three failed attempts to enter the correct password, ME returns +CPIN: PH-SIM PUK (= response to read command AT+CPIN?), i.e. it is now waiting for the Master Phone Code. This is an 8-digit device code associated to the IMEI number of the mobile which can only by obtained from the manufacturer or provider. When needed, contact Siemens AG and request the Master Phone Code of the specific module. There are two ways to enter the Master Phone code: • • You can enter AT+CPIN=Master Phone Code You can use the ATD command followed by the GSM code *#0003*Master Phone Code#;. Usually, the Master Phone Code will be supplied by mail or e-mail. If the received number is enclosed in the *# codes typically used for the ATD option, it is important to crop the preceding *#0003* characters and the appended #. Example: You may be given the string *#0003*12345678#. When prompted for the PH-SIM PUK simply enter 12345678. If incorrectly input, the Master Phone Code is governed by a specific timing algorithm: (n-1)*256 seconds (see table below). The timing should be considered by system integrators when designing an individual MMI.

An 8-digit unlocking code is required to operate the mobile with a different SIM card, or to lift the lock. The code can only be obtained from the provider. Failure to enter the password is subject to the same timing algorithm as the Master Phone Code (see Table above). Call barring: Supported modes are "AO", "OI", "OX", "AI", "IR", "AB", "AG", "AC". If the call barring password is entered incorrectly three times, the client will need to contact the service provider to obtain a new one.

MC55_ATC_V04.00 Confidential / Released Page 102 of 475 3/17/06 5.2 AT+CPIN2 PIN2 Authentication AT+CPIN2 controls network authentication of the MC55. The read command returns an alphanumeric string indicating whether or not network authentication is required. The write command allows the MC55 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. Note that PIN2 can only be entered if PIN1 authentication was done. If the MC55 is requesting SIM PUK2, use <pin> to enter the PUK2, followed by <new pin> to specify the new PIN2.

For example, SIM PIN2 will be needed when you attempt to edit the "FD" phonebook and ME returns "+CME Error 17" or "+CPIN: SIM PIN2". Once the required <pin> has been entered correctly, PIN2 authentication code changes to READY. After 300s, a repetition of the authentication process is required (PIN2 authentication code changes from READY to SIM PIN2).

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. The read command AT^SPIC? indicates which password the number of attempts stated by the execute command actually refers to. Also, the write command may be used to query the counter for a specific password: It indicates the number of attempts still available for entering the password identified by <facility>, for example the PIN, PIN2, PH-SIM PIN etc. To check whether or not you need to enter a password use the read commands AT+CPIN?, AT+CPIN2? and AT^SPIC?. If the response to AT+CPIN? is "READY" the counter of the execute command AT^SPIC relates to PIN2. See last example. If the responses to AT+CPIN? and AT+CPIN2? both read "READY", no password is currently required, and the referrer of the execute command AT^SPIC is explicitly undefined. Syntax Test Command AT^SPIC=?

The AT+CPIN? read command confirms that SIM PIN1 authentication was successful. As SIM PIN1 authentication was successful, the counter relates to SIM PIN2 and correctly indicates that the user has 3 attempts to enter SIM PIN2. Likewise, the read command notifies that the ME is waiting for SIM PIN2. First attempt to enter a wrong SIM PIN1. SIM PIN1 authentication is still valid, and the counter relates to SIM PIN2. Second attempt to enter a wrong SIM PIN1. SIM PIN1 authentication is still valid, and the counter relates to SIM PIN2. Third attempt to enter a wrong SIM PIN1. SIM PIN1 authentication is no longer valid. This time, after the SIM PIN1 code has been disabled, the counter indicates the status of SIM PIN1 and notifies that 10 attempts are left to enter the SIM PUK. To avoid conflicts we recommend to use the AT^SPIC read and write commands rather than the execute command only. The read command clearly states the currently required password, and the write command may be used to get the counter for a specific <facility>, in this case for example "P2".

"PS" may also be factory set. Parameter <class> is not applicable to security locks. See examples below for further details. "SC" SIM (lock SIM cards). SIM requests password upon ME power-up and when this lock command is issued. <password>: SIM PIN1. "PS" Phone locked to SIM card. ME requests password when other than current SIM card is inserted. "PS" lock is frequently referred to as "phone lock", or "device lock". Accordingly, the password may be called "phone code" or "device code". The "PS" password is not associated with the PUK of the SIM card. If incorrectly entered three times, the Master Phone Code is required to lift the lock. This is an 8-digit device code associated to the IMEI number of the mobile which can only by obtained from the manufacturer of the module. 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. MC55_ATC_V04.00 Confidential / Released Page 109 of 475 3/17/06 <password>: User defined password. It is needed before the first use of <facility> "PS" and, therefore, must first be specified with AT+CPWD or AT^SPWD, if it has not been predefined by factory settings. If set by factory (e.g. for a prepaid mobile), the password is supplied by the provider or operator. "FD" SIM fixed dialling memory: If the mobile is locked to "FD", only the phone numbers stored to the "FD" memory can be dialled. (Capacity of FD phonebook depending on the SIM card). <password>: SIM PIN 2. If a lock on the SIM fixed dialing memory is active, the following applies: • Outgoing voice, data or fax calls can be made only to numbers stored in ''FD'' phonebook. Result code depends on the type of the call: for voice calls, indication is ''+CME Error 257: Call barred''. for data and fax calls, indication is ''NO CARRIER''. • Access to defined Supplementary Services such as Call barring, Call waiting, Call forwarding, Call hold and Multiparty is possible only if the exact corresponding public MMI *# code for the desired service is stored in the fixed dialing number phone book, and used with ATD. AT commands for supplementary service control are barred while "FD" lock is active. Indication is ''+CME Error 257: Call barred''. • Access to Unstructured Supplementary Services (''USSD'') is possible only if the exact desired USSD string is stored in the fixed dialling number phone book, and used with ATD. AT commands for USSD are barred while "FD" lock is active. Indication is ''+CME Error 257: Call barred''. • SMS can be sent only to phone numbers which are stored in the ''fixed dialling numbers'' phonebook ''FD''. Indication is ''+CMS Error 302: operation not allowed''. • GPRS commands can be used only if the ''fixed dialling numbers'' phonebook ''FD'' contains an entry with phone number ''*99#''. This single entry enables all GPRS commands, including AT commands and modem compatibility commands like ''ATD*99***1#'' or ''ATD*98***1#''. Indication is ''+CME Error 257: Call barred''. 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. Once a different SIM card is inserted the ME will prompt the client to enter a specific code. This is not the PUK of the SIM card, but usually an 8-digit code which needs to be requested from the provider. The locks can only be set by the manufacturer and need to be agreed upon between the parties concerned, e.g. provider, operator, distributor etc. on the one side and the manufacturer on the other side. For details contact your local dealer or Siemens AG. Parameter <class> is not applicable to SIM locks. <password> and instructions for unlocking must be obtained from the network provider.

The availability of the Supplementary Services varies with the network. To benefit from call barring the client will need to subscribe them, though a limited number of call barring types may be included in the basic tariff package. When you attempt to set a <facility> or <class> which is not provisioned, not yet subscribed to, or not supported by the module, the setting will not take effect regardless of the response returned. The responses in these cases vary with the network (for example "OK", "+CME ERROR: Operation not allowed", "+CME ERROR: Operation not supported" etc.). To make sure check the extended error response with AT+CEER and the lock status with <mode>=2. <password>: Network password supplied from the provider or operator. Usually there is one password which applies to all call barring options. For details contact your provider.

Length and authority for passwords depend on the <facility> in question and are therefore listed in the section on parameter <facility>. Passwords can be modified with AT+CPWD or AT^SPWD. <class>(num) Integer or sum of integers each representing a class of information, i.e. a bearer service, telecommunication service or bearer service group as defined in "GSM 02.04". 1 voice 2 class 2 ("data") comprises all those individual data classes between 16 and 128, that are supported both by the network and the MS. This means, a setting made for class 2 applies to all individual data classes (if supported). In addition, you can assign a different setting to a specific class. For example, you can activate Call Forwarding for all data classes, but deactivate it for data class 64, "dedicated packet access". 4 fax 8 SMS 16 data circuit sync 32 data circuit async MC55_ATC_V04.00 Confidential / Released Page 111 of 475 3/17/06 64 dedicated packet access 128 dedicated PAD access 1...[7]...255 combination of some of the above classes. For example, the default setting 7 represents the sum of the integers 1, 2 and 4 (voice, data and fax). The value 255 covers all classes. If parameter "class" is omitted, the default value 7 is used. Notes • The AT+CLCK command offers the full range of <class> 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.). To make sure check the extended error response with AT+CEER and the lock status with <mode>=2. • The command has been implemented with the full set of <class> parameters according to GSM 07.07. For actual applicability of a desired Call barring service to a specific service or service group (a specific <class> value) please consult table A.1 of GSM 02.04. • If an outgoing Fax or Data Call is rejected due to an active ''call barring'' supplementary service, the call will be terminated with result code NO CARRIER. Under the same conditions, an outgoing Voice call will be terminated with result code NO DIALTONE. • If an invalid <password> is entered several times in succession, a delay incremented after each failed attempt will increase the time to wait before the input of the <password> is accepted. To avoid blocking the serial interface the running AT+CLCK command is aborted after a short timeout and returns CME ERROR 100 ("unknown"). If then the AT+CLCK command is issued once again execution is denied with CME ERROR 256 ("Operation temporary not allowed"). For details regarding the delay see Section 5.1.1, What to do if PIN or password authentication fails?. • If the user tries to set a lock although it is already active or, the other way round, tries to unlock an inactive lock, the response will be OK, but the <password> will not be checked or verified. Examples EXAMPLE 1 Lock SIM card (<facility>= "SC") AT+CLCK="SC",1,"9999" OK AT+CLCK="SC",0,"9999" OK The "SC" parameter enables or disables the SIM PIN authentication (PIN 1) when you power up the GSM engine SIM card locked. As a result, SIM PIN 1 must be entered to enable ME to register to the GSM network. Unlocks SIM card. When powered up, ME registers to the GSM network without requesting SIM PIN1. Note: Depending on the services offered by the provider, this feature is not supported by all SIM card types. If so, the command returns ERROR when you attempt to unlock the card. To query the status of the SIM card lock: AT+CLCK="SC",2 +CLCK: 1 Query the status of SIM card lock. SIM card is locked. SIM PIN1 must be entered to enable ME to register to the GSM network. OK MC55_ATC_V04.00 Confidential / Released Page 112 of 475 3/17/06 EXAMPLE 2 Phone lock (<facility>="PS") AT+CPIN? OK Make sure that PIN1 authentication is valid. To lock the ME to the currently inserted SIM card, first specify a password for <facility> "PS": AT+CPWD="PS",,"1234" OK If "PS" lock has not been set before: enter new password. Optionally, if "PS" password was defined before, change existing password: AT+CPWD="PS","1234","3333" OK To replace existing "PS" password: Enter old and new password. Then, activate the Phone Lock: AT+CLCK="PS",1,"3333" OK Locks the mobile to the current SIM card. To operate the mobile with the SIM card for which "PS" lock was activated: AT+CPIN? +CPIN: SIM PIN OK AT+CPIN="9999" OK No additional password is required for operation (SIM recognized by mobile). To operate the mobile with other SIM card than the one used for the "PS" lock: Enter SIM PIN of present card, followed by "PS" lock password.

ME requests password when other than current SIM card is inserted. "PS" lock is frequently referred to as "phone lock", or "device lock". Accordingly, the password may be called "phone code" or "device code". The "PS" password is not associated with the PUK of the SIM card. It must be defined before the first use of <facility> "PS" with AT+CLCK. <password length>: 4 digits. If incorrectly entered three times, the Master Phone Code is required to lift the lock. This Unblocking procedure is performed with AT+CPWD using the following parameters: <facility>="PS", <old password>= Master Phone Code (to be obtained from the module manufacturer), and <new password>= the new phone code ("PS" password for lock facility), if desired. Mind that successful PIN authentication is a prerequisite for use of AT command AT+CPWD. If Pin authentication has not been completed, input of the Master Phone code password is possible only with AT command AT+CPIN or ATD. For further detail please refer to Section 5.1.1, What to do if PIN or password authentication fails?. 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.

Call related Commands The AT Commands described in this chapter are related to Mobile Originated (MOC, i.e. outgoing) Calls and Mobile Terminated (MTC, i.e. incoming) Calls. 7.1 Call Status Information For Circuit switched calls, including voice, fax and data calls, call status information is available with URC "+CIEV: call" (configurable via AT commands AT+CIND and AT+CMER) or - in more detail - from the list of current calls. This list can be displayed on request via at commands AT+CLCC and AT^SLCC. It can also be issued by the ME in the form of an unsolicited result code "^SLCC" if configured with AT^SLCC and AT+CMER. URC "+CIEV: call" and URC "^SLCC" can be configured using AT command AT^SCFG. An overview of the possible configurations and their consequences for the availability of call status information will be given here. Generally speaking, the call status values recognized by the ME are as follows: • active • held • dialing (MOC) • alerting (MOC) • incoming (MTC) • waiting (MTC) • terminating: The call is not active anymore, but inband information is still available. • dropped: The call has been suspended by the network, but may be resumed later. The values "terminating" and "dropped" are not standardized for AT command AT+CLCC, and therefore only available for command AT^SLCC. A call in any of these two states will not appear in the list of current calls as displayed with AT+CLCC. A call that is not recognized by the ME is considered to be in "unknown" state. Some networks may schedule a traffic channel for a call that is not yet in the "active" state. This is reflected in parameter <traffic channel assigned> of AT command AT^SLCC and the corresponding URC. Depending on the value of AT^SCFG setting <succ>, Indicator "+CIEV" will be issued (if configured with AT+CIND and AT+CMER) • when a state transition ends in state "active" or in state "unknown" (if AT^SCFG setting <succ>=''restricted''). • when any state transition (including transitions beginning or ending in state "unknown") occurs in the list of active calls, or when a traffic channel is established (if AT^SCFG setting <succ>=''verbose''). The indicator value for indicator "+CIEV: call" will be "1" if at least one call is in states "held" or "active", and "0" otherwise. Depending on the value of AT^SCFG setting <sucs>, Indicator "^SLCC" will be issued (if configured with write command AT^SLCC and AT+CMER) • when a state transition ends in state "active" or in state "unknown" (if AT^SCFG setting <sucs>="restricted") • when any state transition (including transitions beginning or ending in state "unknown") occurs in the list of active calls, or when a voice channel is established (if AT^SCFG setting <sucs>="verbose").

Last ! Command Description This command can be used to set up outgoing voice, data or fax calls. It also serves to control Supplementary Services. The termination character ";" is mandatory to set up voice calls or to send *# codes for Supplementary Services. It must not be used for data and fax calls. Additional notes on the responses returned after dialing with ATD: • For voice calls, you have the choice of two different response modes that can be selected with AT^SM20: AT^SM20=1 (factory default) causes the ME to respond once the call setup is completed either successfully ("OK") or unsuccessfully ("NO CARRIER", "NO DIAL TONE", "BUSY"). AT^SM20=0 causes the ME to return "OK" immediately after dialing was completed (i.e. before call setup terminates successfully or unsuccessfully). • For data connections, call setup always terminates when the call has been established (indicated by the result code "CONNECT <text>), or when it fails (indicated by "NO CARRIER"). The settings of AT^SM20 do not apply. Different call release indications: • Upon termination, an outgoing fax or data call may show a different result code than a voice call would show under identical conditions. In order to track down the actual reason for call termination, AT+CEER or ATS18 should be used for all applicable connections. Using ATD during an active call: • When a user originates a second voice call whil there is already an active voice call, the first call will automatically put on hold. The second call attempt is acknowledged with "OK" immediately after dialing with ATD has completed, without relation to a successful call setup. In case of failure, the additional result codes "NO CARRIER", "NO DIAL TONE", "NO CARRIER" will be presented afterwards (see example below). Parameter Description <n>(text) String of dialing digits and optional V.250 modifiers: 0-9, *, #, +, A, B, C The following V.250 modifiers are ignored: ,(comma), T, P, !, W ,@ MC55_ATC_V04.00 Confidential / Released Page 128 of 475 3/17/06 <mgsm>(str) String of GSM modifiers: I Activates CLIR (disables presentation of own phone number to called party) i Deactivates CLIR (enables presentation of own phone number to called party) G Activate Closed User Group explicit invocation for this call only. g Deactivate Closed User Group explicit invocation for this call only.

Call by call invocation of CUG uses the settings provisioned by the provider or, if available, the settings of the parameters <index> and <info> made with AT+CCUG. • The ME is equipped with a "Blacklist" function according to GSM02.07 Annex A: After a predefined number of failed call attempts, the dialed number is entered into a read-only phonebook called "blacklist" (phonebook "BL"). Call attempts to numbers contained in the blacklist will be barred by ME and not signalled to the network. An attempt to start a voice call to a barred phone number will be stopped with a CME ERROR 257 "Call Barred". An attempt to start a data or fax call to a barred phone number will be answered immediately with result code "NO CARRIER". The barred numbers are automatically removed from the blacklist according to the timing conditions specified in GSM02.07 Annex A. • Emergency calls: MC55 supports 112, 911 or 08 (standardized GSM emergency numbers, usable with or without SIM). Example The following example shows the call setup procedure when a call is already active and a second call attempt fails because the line of the called party is busy: atd03012345678 OK ATD03022222222 OK BUSY MC55_ATC_V04.00 Confidential / Released Dialing out the first party's number.

Parameter Description <n>(num)(&W)(&V) 000(&F) Automatic answer mode is disabled. 001-255 Enable automatic answering after specified number of rings. Notes • This command works for MT data and fax calls. • Autoanswering of CSD data and fax calls is supported on ASC0/Mux1 only. • A CSD call will not be automatically answered when the module is in GPRS online mode, but it is possible in GPRS command mode. The application can detect a call by evaluating the RING line and determine whether to change into GPRS command mode or stay in GPRS online mode until GPRS is available again. To answer, to reject or to wait for automatically answering the incoming call the application has to switch into GPRS command mode. • If <n> is set to higher values, the calling party may hang up before the call is automatically answered. • The correlation between ATS7 and ATS0 is important. Example: Call setup may fail if ATS7=30 and ATS0=20. • Setting is local to the interface. It is allowed to have different settings on different interfaces. In such cases the interface 'wins', which is idle and uses the smallest <n> value. • The ATS0 write command is PIN protected. • According to "3GPP TS 27.007 (GSM 07.07): AT command set for User Equipment (UE)", ATS0 is also used as GPRS compatibility command to answer automatically to a network request for PDP context activation (see Section 11.19). Therefore, when the ATS0 write command is issued with <n> greater than 0, the ME will attempt to perform a GPRS attach if not yet attached and if configured to do so (due to the setting AT^SCFG="GPRS/ATS0/withAttach","on"). If the automatic GPRS attach fails the ME keeps trying to attach for approx. 5 minutes, before ATS0 ends up with "ERROR" or "+CME ERROR: unknown", though the new <n> value takes effect. To avoid the risk of long response times to ATS0 in such case take care that the parameter AT^SCFG=<gs0aa> is off, if autoanswer mode is not needed for GPRS or if the mobile works in non-GPRS networks. The GPRS attach will not be performed on recalling a stored user profile with ATZ or on powerup, even though a value <n> greater than 0 was stored in the user profile with AT&W.

ASC0 ASC1 % § MUX1 MUX2 ! ! MUX3 Charge ! ! ! Last ! Command Description This command is only available during a CSD call or a GPRS connection. The +++ character sequence causes the TA to cancel the data flow over the AT interface and switch to command mode. This allows you to enter AT commands while maintaining the data connection to the remote device or, accordingly, the GPRS connection. To prevent the +++ escape sequence from being misinterpreted as data, it must be preceded and followed by a pause of at least 1000 ms. The +++ characters must be entered in quick succession, all within 1000 ms. Notes • To return from command mode to data or PPP online mode: Enter ATO. • In Multiplex mode the +++ sequence does not work. Therefore, if required in Multiplex mode, the escape sequence needs to be implemented in the customer's external Multiplex application. Design solutions, for example using the DTR signal or a modem status command (MSC), can be found in [5], Section "Escape Sequence". See also Section 4.8, AT+CMUX. • On ASC1 the +++ sequence can be used in GPRS connections for switching from PPP online to command mode.

MC55_ATC_V04.00 Confidential / Released Page 148 of 475 3/17/06 7.21 AT^SLCC Siemens defined command to list current calls of ME AT^SLCC covers essentially the same information as GSM 07.07 command AT+CLCC, with the following additions: • The execute command response contains an additional parameter <traffic channel assigned> indicating whether the call has been assigned a traffic channel by the network (transmission of data or inband information is possible). • The additional write command allows to activate Event reporting for the list of current calls. If event reporting is active for an interface, a call status transition (cf. Call Status Information) and (if desired) the assignment of a traffic channel will generate an event report indication to this interface. In order to receive this event report as an URC, the URC presentation mode for this interface has to be configured with AT+CMER. The frequency of event report generation can be configured with AT command AT^SCFG. Refer to Call Status Information for further detail on the configuration options. • The additional read command allows to determine the event reporting mode <n> which indicates whether the interface receives event report indications for the list of current calls. Mind that the URC will be displayed only if the URC presentation mode for the interface concerned has been configured with AT+CMER. Syntax Test Command AT^SLCC=?

The list is displayed in the state it has at the time of display, not in the state it had when the signal was generated. The URC's occurrence indicates call status changes for any of the calls in the list of current calls. Please refer to Call Status Information and AT^SCFG for further information about the configuration of this URC. Event reporting can be enabled separately for each interface. Interface settings are saved with AT&W and can be displayed with AT&V. Additionally, The URC presentation mode for the interface must be configured with AT+CMER. Depending on the value of AT^SCFG setting <sucs>, Indicator "^SLCC" will be issued (if configured with write command AT^SLCC and AT+CMER) • when a state transition ends in state "active" or in state "unknown" (if AT^SCFG setting <sucs>="restricted") • when any state transition (including transitions beginning or ending in state "unknown") occurs in the list of active calls, or when a traffic channel is established (if AT^SCFG setting <sucs>="verbose"). If multiple displays of identical list configurations occur, this happens because of short intermediate states of the list, that have already been overridden by new transitions and states. Thus, it is guaranteed that the configuration displayed is always the current configuration at the time of the last display. The list of active calls displayed with this URC will always be terminated with an empty line preceded by prefix ''^SLCC: '', in order to indicate the end of the list. Command Description The read command returns an indication whether event reporting is active for the current interface. The exec command returns a list of current calls of ME. If command is successful, but no calls are available, no information response is sent to TE. Use the write command to activate or deactivate event reporting for URC "^SLCC". Event reporting can be enabled separately for each interface. Interface settings are saved with AT&W and can be displayed with AT&V.

The maximum displayed length of <alpha> is 16 characters. If <alpha> has more than 16 characters, only the first 15 characters will be displayed. To indicate an overflow, a special character will be used as the 16th character. This will be a space if the character set selected with AT+CSCS is 'GSM', or 'E400' if the character set is 'UCS2'. Due to time constraints on the necessary evaluation of the phonebook, this parameter may show a default value during early call phases (e.g. for <stat>= ''dialing'', ''incoming'' or ''alerting''), even if a phonebook entry is present for the number concerned. Notes • Teleservices other than voice, data, fax are not fully supported by ME. They are used only in connection with the handling for AT+CSNS, and may therefore occur in parameter <mode> for mobile terminated calls. • If a URC "^SLCC" in verbose mode (see AT^SCFG) has been buffered while the interface was in dedicated mode (depending on the settings of AT+CMER parameter <bfr>), each buffered event indicator will be output as a separate URC after the interface returns to idle mode. However, the output will deliver the list of current calls in the "current" state (at the time when the output is generated), possibly leading to multiple displays of identical list configurations. • Some parameters of AT command AT+CHLD, as well as some situations where the call status in the network changes very quickly (e.g. the transition between <stat>= ''unknown'', ''dialing'' and ''alerting'' for a call to a reachable subscriber within the registered network) may lead to quasi-simultaneous changes to the states of one or several calls in the list, possibly leading to multiple displays of identical list configurations. • If multiple displays of identical list configurations occur, this happens because of intermediate states of the list, that have already been overridden by new transitions and states. Thus, it is guaranteed that the configuration displayed in such cases is the current configuration at the time of the last display. • It is adviseable to receive URC "^SLCC" on an interface that is not used for call initiation, if verbose output is configured. If only voice calls are expected, a setting of AT^SM20= 0 may be used alternatively in order to keep the call from blocking the interface.

MC55_ATC_V04.00 Confidential / Released Page 162 of 475 3/17/06 8.2 AT+COPS Operator Selection AT+COPS queries the present status of the MC55's network registration and allows to determine whether automatic or manual network selection shall be used. Additional service is available with AT^SOPS. Three operator selection modes are available: • Automatic MC55 searches for the home operator automatically. If successful the MC55 registers to the home network. If the home network is not found, MC55 goes on searching. If a permitted operator is found, MC55 registers to this operator. If no operator is found the MC55 remains unregistered. • Manual Desired operator can be determined using the AT+COPS write command. If the operator is found, MC55 registers to it immediately. If the selected operator is forbidden, the MC55 remains unregistered. • Manual/automatic The ME first tries to find the operator determined via AT+COPS write command. If the ME fails to register to this operator, then it starts to select another (permitted) operator automatically. The AT+COPS test command lists sets of four parameters, each representing an operator present in the network. A set consists of • an integer indicating the availability of the operator, • long alphanumeric format of the operator's name and • numeric format representation of the operator. Any of the parameters may be unavailable and will then be an empty field (,,). The list of operators comes in the following order: Home network, networks referenced in SIM and other networks. The operator list is followed by a list of the supported <mode>s and <format>s. These lists are delimited from the operator list by two commas. If the test command is used during an ongoing GPRS transfer, traffic will be interrupted for up to one minute. The AT+COPS read command returns the current <mode> and the currently selected operator. If no operator is selected, <format> and <oper> are omitted. The AT+COPS write command forces an attempt to select and register to the GSM network operator (see note below). If the selected operator is not available, no other operator will be selected (except <mode>=4). The selected operator name <format> will apply to further read commands, too. Command settings are effective over all serial interfaces of the MC55. Syntax Test Command AT+COPS=?

MC55_ATC_V04.00 Confidential / Released Page 164 of 475 3/17/06 Note • It is not recommended to use the AT+COPS command before passing the CHV (card holder verification) / SIM PIN1 verification. This is because after PIN1 verification the module will automatically try to register to the network as though AT+COPS were 0, regardless of the settings done before with or without SIM, such as AT+COPS=2 which remains unchanged. Also, the test command should only be used after PIN1 authentication. MC55_ATC_V04.00 Confidential / Released Page 165 of 475 3/17/06 8.3 AT^SOPS Extended Operator Selection AT^SOPS queries the present status of the MC55's network registration. Since basic operator selection services are available with AT+COPS this command uses the methods of the Enhanced Operator Name String (EONS) specification while handling operator name strings. Additional EONS related information is available with AT^SIND. AT^SOPS test command lists sets of five parameters, each representing an operator present in the network. A set consists of 1. an integer indicating the availability of the operator, 2. specification of the source of the operator name <eonsOperator>, 3. operator name according to EONS Table, 4. Service Provider Name from the SIM Service Table and 5. numeric format representation of the operator. Any of the parameters may be unavailable and will then be an empty field (,,). The list of operators comes in the following order: Home network, networks referenced in SIM and other networks. After the operator list the MC55 returns lists of supported <mode>s and <format>s. These lists are delimited from the operator list by two commas. If the test command is used while an ongoing GPRS transfer, traffic will be interrupted for up to one minute. Command settings are effective over all serial interfaces of the MC55. Syntax Test Command AT^SOPS=?

See also AT+CHLD • Users should be aware that if call waiting is activated (<mode>=1), the presentation of URCs needs to be enabled, too (<n>=1). Otherwise, on the one hand, a waiting caller would be kept waiting due to lack of BUSY signals, while, on the other hand, the waiting call would not be indicated to the called party. • The AT+CCWA command offers a broad range of options according to the GSM specifications. However, when you attempt to enable call waiting for a <class> for which the service is not provisioned or not supported , 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.). To make sure check the current call waiting settings with <mode>=2. • The AT+CCWA command has been implemented with the full set of <class> parameters according to GSM 07.07. For actual applicability of SS call waiting to a specific service or service group (a specific <class> value) please consult table A.1 of GSM 02.04 • Despite the specifications stated in GSM 02.04 call waiting is not handled uniformly among all networks: GSM 02.04, Annex A, provides the following specification: "The applicability of call waiting refers to the telecommunication service of the active call and not of the waiting call. The incoming, waiting, call may be of any kind." Nevertheless, networks do differ on the actual implementation of the service. For example, the activation of call waiting for <class> 4, "fax", causes some networks to send a call waiting indication if a call "of any kind" comes in during an active fax call, but others may (with the same settings active) indicate a waiting fax call during any kind of active call. Thus, the only reliable way to receive or prevent a call waiting indication under any circumstances and in any network, is to activate or deactivate call waiting for all tele- and bearer services (<class> 255).

Command Description TA controls the Supplementary Services Call Hold and Multiparty. Calls can be put on hold, recovered, released, and added to a conversation. Like for all Supplementary Services, the availability and detailed functionality of Call Hold and Multiparty services depends on the configuration of the GSM network. The MC55 can only request the service, but the network decides whether and how the request will be answered. Parameter Description <n>(num) 0 1 Release all held calls or set User Determined User Busy (UDUB) for a waiting call: • If a call is waiting, release the waiting call. The calling party will receive a "BUSY" indication (Supplementary Service User Determined User Busy "UDUB") • Otherwise, terminate all held calls (if any). Terminate all active calls (if any) and accept "the other call" as the active call: • If a call is waiting, the waiting call will be accepted. • Otherwise, if a held call is present, the held call becomes active. 1X Terminate a specific call X (X= 1-7). The call may be active, held or waiting. The remote party of the terminated call will receive a "NO CARRIER" indication. Parameter X is the call number <idx> of the targeted call in the list of current calls available with AT command AT+CLCC. 2 Place all active calls on hold (if any) and accept "the other call" as the active call: • If a call is waiting, the waiting call will be accepted. • Otherwise, if a held call is present, the held call becomes active. 2X Place all active calls except call X (X= 1-7) on hold. Parameter X is the call number <idx> of the targeted call in the list of current calls available with AT command AT+CLCC. 3 Add a held call to the active calls in order to set up a conference (multiparty) call. MC55_ATC_V04.00 Confidential / Released Page 206 of 475 3/17/06 Notes • The AT+CHLD command offers a broad range of options according to the GSM specifications. However, if you attempt to invoke an option which is not provisioned by the network, or not subscribed to, invocation of this option will fail. The responses in these cases may vary with the network (for example "Operation not allowed", "Operation not supported" etc.). • The handling of the supplementary service Call hold and Multiparty varies with the types of calls. This is because only voice calls can be put on hold, while data or fax calls cannot. The following procedures apply: With AT+CHLD=2 the user can simultaneously place a voice call on hold and accept another waiting voice, data or fax call. If the waiting call is a data or fax call, it is also possible to put the voice call on hold. To switch back from the active data or fax call to the held voice call the active call must be terminated with AT+CHLD=1. If all active and held calls are voice calls it is possible to switch back and forth with AT+CHLD=2. • In conflict situations, e.g. when a waiting call comes while there are already held calls, the above procedures apply to the waiting call only. For example, <n>=0 rejects the waiting call, but does not affect the held calls. • See also the AT+CCWA command for details on how to display waiting calls.

Internet Service Commands MC55 has an embedded TCP/IP stack that is driven by AT commands and enables the host application to easily access the Internet. The advantage of this solution is that it eliminates the need for the application manufacturer to implement own TCP/IP and PPP stacks, thus minimizing cost and time to integrate Internet connectivity into a new or existing host application. This chapter is a reference guide to all the AT commands and responses defined for use with the TCP/IP stack. Access is provided to the following Internet Services: 1. Socket Client and Server for TCP, Client for UDP 2. FTP Client 3. HTTP Client 4. SMTP Client 5. POP3 Client Two design strategies for using Internet Service AT commands - URC mode or polling mode: The MC55 offers two modes of controlling an Internet session opened with AT^SISO. To select the mode that best suits the preferences of your application design use the AT^SCFG command, parameter "Tcp/WithURCs" (refer to <tcpWithUrc>). • URC mode (delivery default): The progress of an Internet session is URC driven. The URCs notify the host whether data can be sent or received, whether data transfer has completed, whether the service can be closed or whether an error has occurred. This mechanism eliminates the need to poll the service until the necessary progress information is received. To enable the URC mode select: AT^SCFG="Tcp/WithURCs",on. • Polling mode: In polling mode, the presentation of URCs related to the Internet Services is disabled. The host is responsible to retrieve all the status information needed for controlling the Internet session. This is done by polling, where the host application keeps sending the commands AT^SISR, AT^SISW, AT^SISI. To enable the polling mode select: AT^SCFG="Tcp/WithURCs",off. The disabled URCs are the following: "^SISR" URC, "^SISW" URC and "^SIS" URC for parameter <urcCause>=0 (Internet service events), but not for <urcCause>=1 or 2 (needed for Socket listener and always enabled). Step-by-step overview of how to configure and use TCP/IP communications with MC55: • Select URC mode or polling mode as described above. • First of all, create a CSD or GPRS connection profile with AT^SICS. The connection profile is a set of basic parameters which determines the type of connection to use for an Internet service. The connection type is also referred to as bearer. Up to 6 connection profiles can be defined, each identified by the <conProfileId>. • Secondly, use AT^SISS to create a service profile based on one of the connection profiles. Up to 10 service profiles can be defined, each identified by the <srvProfileId>. The service profile specifies the type of Internet service to use, i.e. Socket, FTP, HTTP, or one of the email services SMTP or POP3. To assign a connection profile to a service profile, the <conProfileId> of AT^SICS must be entered as "conId" value of the AT^SISS parameter <srvParmTag>. This offers great flexibility to combine connection profiles and service profiles. For example, you may have one connection profile (CSD or GPRS) specified with AT^SICS which can be associated with an SMTP service profile for sending emails and a POP3 service profile for retrieving emails. • Once the connection profile and the service profile are created, an Internet session can be opened by entering the AT^SISO write command and the desired <srvProfileId>. In URC mode, the "^SISR" or "^SISW" URC indicates whether the service is ready to receive or send data. This means, that the AT^SISR or AT^SISW command shall be entered after the URC was received. If an error occurs the "^SIS" URC is delivered instead. In polling mode, you can enter the AT^SISR or AT^SISW command straight after AT^SISO though you may MC55_ATC_V04.00 Confidential / Released Page 219 of 475 3/17/06 • • • • • need to do so several times until the service confirms that data can be sent or received. The first parameter of the AT^SISR or AT^SISW commands is always the <srvProfileId>, the second parameter is the number of bytes which the host either wants to send to or is able to receive from the module. The way the module handles the data transfer follows the rules of the ordinary socket interface and is aware that a host may be limited by its input buffer size. The maximum data size supported by MC55 is 1500 bytes in both directions (read or write). To send or receive more than 1500 bytes, the read or write action shall be repeated until the data transfer has completed. Each read or write action requires that the command response (of AT^SISR or AT^SISW) confirms that the service is ready to send or receive data. To end an upload data stream set the <eodFlag> in the last AT^SISW command. The AT^SISI command shall be used to monitor the progress of the session. The command reports the service state of the used service profile and indicates the number of bytes received, the number of bytes sent and, in the case of sending, the number of bytes acknowledged or unacknowledged at TCP layer. If an error occurs during a session you can enter the AT^SISE command and the <srvProfileId> to identify the reason. This is especially important in polling mode. The AT^SICI command can be used any time to query the current status of one or all connection profile(s). Finally, to end a session, enter the AT^SISC write command and the <srvProfileId>. Maximum number of profiles defined / used: • Up to 6 connection profiles can be created (with AT^SICS). • Up to 10 service profiles can be created (with AT^SISS), but the number of parallel profiles of the same service type is limited as listed below. If the maximum number of a service profile type is already defined, any attempt to set up another profile for the same type will be denied with "+CME ERROR: operation of service temporary not allowed". • - Maximum 3 HTTP profiles - Maximum 6 socket profiles: The socket service can accept an incoming connection only when at least one service profile is still free (not yet created with AT^SISS), otherwise the incoming connection will be rejected from the listener. - 1 FTP profile - 1 POP3 profile - 1 SMTP profile The TCP/IP stack of MC55 supports one service profile at a time. Trying to run more than one service profile may result in a blocking of one of these service profiles. Using Internet Service AT commands on several interfaces (ASC0, ASC1 or Multiplex mode on ASC0): • A connection profile can be created on one interface and then viewed or changed on all other interfaces. • A service profile can be used only on one interface at a time: - Service profiles can only be opened on the interface where they have been defined with AT^SISS. - Accordingly, on each interface the read commands AT^SISO? and AT^SISI? deliver full status information for the service profiles configured / opened on this interface, while service profiles related to other interfaces are only listed by <srvProfileId> and service type name (= <srvParmTag> value "srvType") without any status parameters. - Changes to a service profile are allowed only on the same interface where it was created, trying to change it on another interface is denied with "+CME ERROR: Invalid index". If queried with the read command AT^SISS? the entire profile is returned on the interface where the service profile was created, while on all other interfaces only the service type of the profile is stated. - To free a service profile for use on another interface, use the AT^SISS command and select service type = "none". This action deletes the entire profile and restores all parameters of the profile to their initial power-up state (all values are empty). For example, to remove the service profile 3, set AT^SISS=3,srvType,none. After this, a new profile 3 can be created on any other interface.

Timeouts Timeouts are not part of the Internet AT command functionality implemented in MC55 and, if desired, are the responsibility of the host application. It is recommended that the host application validates URCs and AT command responses and reacts adequately, for example by sending a close message or starting a timer. Socket UDP client The significant differences between the TCP and UDP protocols imply that UDP sometimes requires particular procedures or even specific parameters. Details on how to handle UDP services can be found in extra notes or are included in the general parameter descriptions. Using the DCD line to detect the connection status of Internet services With AT&C you can configure the DCD line of the used serial interface to indicate whether an Internet service is active. For Socket, HTTP, SMTP and POP3 the states "Up" or "Connecting" are indicated, for FTP only the state "Up". MC55_ATC_V04.00 Confidential / Released Page 221 of 475 3/17/06 10.1 AT^SICS Internet Connection Setup Profile AT^SICS serves to create and edit Internet connection profiles. A connection profile can be assigned to one or more service profiles defined with AT^SISS, and thus, determines which type of connection is to be established when opening a service profile with AT^SISO. The AT^SICS read command requests the current settings of all Internet connection profiles. One line is issued for every possible parameter of a given <conParmTag> "conType" value. The AT^SICS write command specifies all parameters of a connection profile identified by <conProfileId>. At first the type of Internet connection needs to be selected via <conParmTag> value "conType". This determines the applicability of all other <conParmTag> values related to this "conType" and automatically sets their defaults. An exception is the <conParmValue-alphabet> which can be set before or after selecting "conType". To change the settings the write command needs to be executed for each single <conParmTag>. All profile parameters set with AT^SICS are volatile. MC55 supports the authentication methods PAP (Password Authentication Protocol), CHAP (Handshake Authentication Protocol) or none. The method actually used for an Internet connection via CSD or GPRS is negotiated at the LCP layer, i.e. it is negotiated with the remote peer at connection setup.

"conType" Type of Internet connection. For supported values of <conParmValue> refer to <conParmValue-conType>. "alphabet" Selects the character set for input and output of string parameters within a profile. The selected value is bound to the specific profile. This means that different profiles may use different alphabets. Unlike other parameters the alphabet can be changed no matter whether the <conParmTag> value "conType" has been set. For supported values of <conParmValue> refer to <conParmValuealphabet>. "user" User name string: maximum 32 characters (where "" is default). "passwd" Password string: maximum 32 characters (where ***** is default). "apn" Access point name string value: maximum 100 characters (where "" is default).

"calledNum" Called BCD number. "dataType" Data call type. For supported values of <conParmValue> refer to <conParmValuedataType>. "dns1" Primary DNS server address (IP address in dotted-four-byte format). This value determines whether to use the DNS server addresses dynamically assigned by the network or a specific DNS server address given by the user. "dns1" = "0.0.0.0" (default) means that the CSD or GPRS connection profile uses dynamic DNS assignment. Any other address means that the Primary DNS is manually set. The default value applies automatically if no other address is set. Note that the AT^SICS read command only returns a manually configured IP address, while the value "0.0.0.0" is not indicated at all, no matter whether assumed by default or explicitly specified. See also note below. MC55_ATC_V04.00 Confidential / Released Page 223 of 475 3/17/06 "dns2" Secondary DNS server address (IP address in dotted-four-byte format).

When a service based on a GPRS connection profile is started after entering AT^SISO MC55 automatically tries to attach to the GPRS. Yet, the only exception is AT+CGATT which can be used any time to detach from the GPRS and, and thus disconnect the bearer opened with AT^SISO. "none" Clears the connection profile. <conParmValue-alphabet>(str) Character set selectable with <conParmValue> for <conParmTag> value "alphabet". ["0"] Character set determined with AT+CSCS applies. "1" International Reference Alphabet (IRA, seven bit ASCII) applies. <conParmValue-dataType>(str) Supported data call type values in <conParmValue> for <conParmTag> value "dataType". "0" ISDN ["1"] Analog Notes • Before opening a service profile based on a connection profile recently used, check with AT^SICI that the previous connection was properly closed. If AT^SICI confirms that the connection profile is in <conState> 0 (Down) the connection profile may be used again. • If a GPRS network does not support or is not correctly configured for automatic DNS address assignment the TCP/IP stack cannot resolve fully qualified domain names. In this case, a warning message will be returned when trying to open an Internet service configured for automatic DNS address assignment. 10.1.1 Example: Default values of a CSD connection profile As stated earlier, the "conType" selected with AT^SICS determines all other matching profile parameters related to this "conType".

Any service profile can then be used to control a data link in conjunction with AT^SISI, AT^SISO, AT^SISC, AT^SISR, AT^SISW and AT^SISE. The AT^SISS read command requests the current settings of all Internet service profiles. One line is issued for every possible parameter of a given <srvParmTag> "srvType" value. The AT^SISS write command specifies the parameters for a service profile identified by <srvProfileId>. At first the type of Internet service needs to be selected via <srvParmTag> value "srvType". This determines the applicability of all other <srvParmTag> values related to this "srvType" and sets their defaults. Changing the <srvParmTag> "srvType" of an existing service profile will reset all <srvParmTag> default values to suit the new "srvType". An exception is the <srvParmValue-alphabet> which can be set before or after selecting "srvType" and is not reset when "srvType" changes. To change the settings the write command needs to be executed for each single <srvParmTag>. All profile parameters set with AT^SISS are volatile. The list below shows which <srvParmTag> parameters apply to each Internet service and which of them are mandatory or optional.

Length: 0 ... 127 Can be used to transfer a small amount of data. The content of this string will only be sent if "hcContLen" = 0. The maximum length of "hcContent" is 127 bytes. To transmit a larger amount of data "hcContLen" must be set to a non-zero value. In this case the "hcContent" string will be ignored, and data transmission from the client to the server is done with AT^SISW. hcContLen Mandatory parameter for HTTP method "Post". Length: 0 ... 231-1 The content length shall be set in the header of the HTTP "Post" request before the data part is transferred. If "hcContLen" = 0 then the data given in the "hcContent" string will be posted. If "hcContLen" > 0 then the AT^SISW command will be used to send data from the client to the server. In this case, "hcContLen" specifies the total amount of data to be sent. The data can be sent in one or several parts. For each part, the transmission is triggered by the URC "^SISW: x, 1", then the AT^SISW write command can be executed. After the exact number of bytes are transferred via MC55_ATC_V04.00 Confidential / Released Page 232 of 475 3/17/06 the serial interface, the HTTP client will go from service state "Up" to service state "Closing" (see parameters <srvState> and <srvState> for detail). Finally, the URC "^SISW: x, 2" indicates that all data have been transferred and the service can be closed with AT^SISC. hcUsrAgent The user agent string must be set by the application to identify the mobile. Usually operation system and software version info is set with this browser identifier. Length: 0 ... 63 hcMethod HTTP method specification: 0=GET, 1=POST, 2=HEAD. hcProp Parameter for several HTTP settings. Length: 0 ... 127 The general format is 'key': <space> 'value' "\0d\0a". Multiple settings can be given separated by "\0d\0a" sequences within the string. Possible 'key' values are defined at HTTP/1.1 Standard RFC 2616. hcRedir This flag controls the redirection mechanism of the MC55 acting as HTTP client (numeric). If "hcRedir" = 0: No redirection. If "hcRedir" = 1: The client automatically sends a new HTTP request if the server answers with a redirect code (range 30x). Default is 1. hcAuth If set ("hcAuth" = 1) this flag determines that the HTTP client will automatically answer on authentication requests from the server with the current "passwd" and "user" parameter settings. If these parameters are not specified the MC55 will terminate the HTTP connection and send an indication to the TA. Default is 1. smFrom Email sender address, i.e. "MAIL FROM" address (string). Length: 6 ... 256 A valid address parameter consists of local part and domain name delimited by a '@' character, e.g. "[email protected]". smRcpt Recipient address of the email, i.e. "RCPT TO" address (string). Length: 6 ... 256 If multiple recipient addresses are to be supplied the comma character is used as delimiter to separate individual address values, e.g. "[email protected],[email protected]". smCC CC recipient address of the email (string). Length: 6 ... 256 If multiple CC recipient addresses are to be supplied the comma character is used as delimiter to separate individual address values, e.g. "[email protected],[email protected]". smSubj Subject content of the email (string). Length: 0 ... 256 If no subject is supplied the email will be sent with an empty subject. smHdr This parameter, if set, will be appended at the end of the email header section (string). Length: 0... 256 Hence, it serves as a generic header field parameter which allows the user to provide any email header field. It is the user's responsibility to provide correct header fields! String of max. 256 characters. Example for multipart MIME messages: "Content-Type: multipart/mixed". smAuth SMTP authentication control flag (numeric). If disabled (<srvParmValue> "0" by default), MC55 performs action without SMTP authentication. If enabled (<srvParmValue> "1") authentication procedure with the SMTP server will be performed by means of supported authentication methods, using MC55_ATC_V04.00 Confidential / Released Page 233 of 475 3/17/06 values of "user" and "passwd" parameters. If MC55 and SMTP server are not able to negotiate an authentication mechanism supported by both parties, the MC55 continues action without authentication. MC55 supports SMTP authentication. pCmd POP3 user command to be executed by the POP3 service (numeric). For supported values of <srvParmValue> refer to <srvParmValue-pCmd>. pNumber Optional message number argument used by the POP3 commands List ("2"), Retrieve ("3") and Delete ("4"). For POP3 commands see <srvParmTag> value "pCmd". Length: 0 ... 232-1 If no specific value is set in the service profile, the value "0" is assumed by default, i.e. "pNumber" is disabled. pLength Maximum message length (string, optional) Length: 0 ... 232-1 "pLength" can be used to specify the length of the message(s) to be retrieved from or deleted on the POP3 server. If no specific value is set in the service profile, the default value "0" is assumed, which means that there is no limit on the message size. A warning will be issued inthe following cases: • If "pNumber" > 0 and a specific message to be retrieved from / deleted on the server is longer than "pLength". • If "pNumber" = 0 and all messages to be retrieved from / deleted on the server are longer than "pLength". No warning will be issued in the following cases: • If there are no messages at all on the server. • If the server has message(s) below and above the "pLength" specified. In this case, the message(s) within the range of "pLength" can be successfully retrieved or deleted, but the message(s) above "pLength" remain on the server without any further notification given to the user. • Therefore, after retrieving / deleting messages, it is recommended to check the message status on the server. This can be done by adding a further POP3 service profile using the POP3 user command List ("2"). pDelFlag Flag to be used with the POP3 user command Retrieve ("3"). Specifies whether or not to delete retrieved emails on the server (optional). For supported values of <srvParmValue> refer to <srvParmValuepDelFlag>. tcpMR Parameter can be used to overwrite the global AT^SCFG parameter "Tcp/ MaxRetransmissions" <tcpMr> for a specific Internet Service connection profile. If the parameter is not specified the value specified with AT^SCFG will be used. Supported values <srvParmValue> for this parameter are the same as described for <tcpMr>. Setting is not relevant for Internet Service "Socket" whit type "UDP". tcpOT Parameter can be used to overwrite the global AT^SCFG parameter "Tcp/OverallTimeout" <tcpOt> for a specific Internet Service connection profile. If the parameter is not specified the value specified with AT^SCFG will be used. Supported values <srvParmValue> for this parameter are the same as described for <tcpOt>. Setting is not relevant for Internet Service "Socket" whit type "UDP". <srvParmValue>(str) Parameter value; type and supported content depend on related <srvParmTag>. MC55_ATC_V04.00 Confidential / Released Page 234 of 475 3/17/06 <srvParmValue-srvType>(str) Supported Internet service type values in <srvParmValue> for <srvParmTag> value "srvType". Before changing the "srvType" of an existing service profile be sure that the profile is closed. To verify the connection state of the service profile enter the read command AT^SISI. Only when <srvState>=2 is returned for this specific service profile you can change its service type. "Socket" MC55 acting as client or server (listener) for TCP, or as client for UDP. If MC55 is listener at least two service profiles are required. The first socket profile must be configured as listener. The second service profile will be dynamically assigned when a socket connection request from a remote client is incoming. For this purpose, one service profile must be left free (= not configured with AT^SISS). An incoming socket connection request will be indicated by the "^SIS" URC, with the next free <srvProfileId> shown inside the URC as parameter <urcInfoId>. The connection request can be accepted or rejected by using the commands AT^SISO or AT^SISC and the ID retrieved from the "^SIS". "Ftp" MC55 acting as FTP client. "Http" MC55 acting as HTTP client. "Smtp" MC55 acting as SMTP client. "Pop3" MC55 acting as POP3 client. "none" Reset Internet service profile settings. Operation is not allowed if profile is in use, i.e. it was activated via AT^SISO. <srvParmValue-alphabet>(str) Supported string parameter character set selections in <srvParmValue> for <srvParmTag> value "alphabet". ["0"] Applicable character set is determined by current setting of AT+CSCS. "1" International Reference Alphabet (IRA, seven bit ASCII). <srvParmValue-pCmd>(num) Supported POP3 user command values in <srvParmValue> for <srvParmTag> value "pCmd". 1 Status command. This command retrieves the "drop listing" of a POP3 server. A "drop listing" consists of a single line containing the number of messages in the maildrop list followed by the total size of the maildrop list in bytes. Each drop listing will be finished by a so-called "dotline", i.e. a new line with just a single dot. 2 List command. If <srvParmTag> value "pNumber" is set to a non-zero value the "List" command returns the "scan listing", consisting of a single line which contains the message number and the message size in bytes if the specified message exists in the maildrop list on the POP3 server. If no such message exists on the server than the POP3 service issues an error response to the user. If <srvParmTag> value "pNumber" is zero the "List" command returns a multiline "scan listing". For each message on the maildrop list of the server the POP3 service returns a line containing the message number and its size in bytes. A final "dotline" will be printed at the end of the "scan listing". If there are no messages on the maildrop list of the server, the POP3 service returns a positive response, i.e. it doesn't issue an error response, but the "scan listing" will be empty. In either case, each scan listing will be finished by a so-called "dotline", i.e. a new line with just a single dot. MC55_ATC_V04.00 Confidential / Released Page 235 of 475 3/17/06 3 Retrieve command. If <srvParmTag> value "pNumber" is set to a non-zero value this command retrieves the related message from the POP3 server's maildrop list. If no such message exists on the server the POP3 service issues an error response to the user. It depends on the parameter "pDelFlag" if the message will be deleted from the POP3 server upon successful retrieval. If <srvParmTag> value "pNumber" is zero the "Retrieve" command returns all messages pending in the POP3 server's maildrop. If there are no messages on the maildrop list of the server the POP3 service returns with a positive response, i.e. it doesn't issue an error response, but the returned list will be empty. Each email will be finished by a so-called "dotline", i.e. a new line with just a single dot. 4 Delete command If <srvParmTag> value "pNumber" is set to a non-zero value the command deletes the related message from the POP3 server's maildrop list. In fact, the message is marked as deleted on the server and will be deleted permanently if the POP3 service command executes successfully. In case an error has occurred, e.g. network loss, the message will not be deleted on the server even though the POP3 service command has been finished. If <srvParmTag> value "pNumber" is zero the "Delete" command deletes all messages from the POP3 server's maildrop list. In fact, the messages are marked as deleted on the server and will be deleted permanently if the POP3 service command executes successfully. In case an error has occurred, the messages will not be deleted on the server even though the POP3 service command has been finished. <srvParmValue-pDelFlag>(num) Supported flag values in <srvParmValue> for <srvParmTag> value "pDelFlag". Only applicable if the profile contains the POP3 user command Retrieve ("3"). [0] Messages will not be deleted on the server. 1 Delete messages on the server which have been retrieved successfully. Note • String parameters are truncated if greater than the maximum length specified above.

MC55_ATC_V04.00 Confidential / Released Page 238 of 475 3/17/06 10.5 AT^SISO Internet Service Open The AT^SISO write command starts the Internet session configured by the service profile. All further steps needed to control the session depend on whether you are using URC mode or polling mode. The AT^SISO read command returns the current status of all services. URC mode: If the service opens successfully, the URCs "^SISW" and "^SISR" will trigger the action to follow, either writing data with AT^SISW or reading data with AT^SISR. To terminate an upload data stream set the <eodFlag> within the last AT^SISW command. If the URCs notify that a data transfer has been successful ("^SISR: x, 2" or "^SISW: x, 2"), the service can be closed with AT^SISC. If a special event occurs, e.g. an error or a warning, after opening or while using a service then the URC type "^SIS" will be delivered. Polling mode: After opening the service, all progress information needed to control the session shall be explicitly requested by the host application. The particular sequence of AT commands varies depending on the service used. The following list summarizes, by way of an example, the steps normally involved in managing an upload or download job. • Upload (Socket, FTP, HTTP, SMTP): • • - Enter the AT^SISO command, e.g. AT^SISO=9. - Enter AT^SISW, specify <reqWriteLength>, e.g. AT^SISW=9,20. Check resulting response for <cnfWriteLength>. Optionally, check error with AT^SISE, e.g. AT^SISE=9. If necessary, repeat the sequence several times. - Enter last AT^SISW command and enable <eodFlag>, e.g. AT^SISW=9,0,1. 1) If Socket service: Query available data with AT^SISR, e.g. AT^SISR=9,1430. - Check service state with AT^SISI, e.g. AT^SISI=9, if necessary several times until <srvState>=6 ("Down"). - Check error with AT^SISE, e.g. AT^SISE=9. - Close service with AT^SISC, e.g. AT^SISC=9. Download (Socket, FTP, HTTP, POP3): - Enter the AT^SISO command, e.g. AT^SISO=9. - Enter AT^SISR, specify <reqReadLength>, e.g. AT^SISR=9,1000. Check resulting response for <cnfReadLength>. If necessary, repeat the sequence several times until <cnfReadLength>= -2 (end of data) or ERROR. - Check error with AT^SISE, e.g. AT^SISE=9. - Close service with AT^SISC, e.g. AT^SISC=9. Socket service (upload and download possible in one session): - Recommended: Set AT+CMEE=2 to enable extended error text. - Enter the AT^SISO command, e.g. AT^SISO=9. - Enter AT^SISR or AT^SISW, specifying <reqReadLength> or <reqWriteLength>, e.g. AT^SISR=9,20 or AT^SISW=9,20. Check resulting response for <cnfReadLength> or <cnfWriteLength>. If necessary, repeat the sequence several times. - Check error with AT^SISE, e.g. AT^SISE=9. - If write action: Enter last AT^SISW command and enable <eodFlag>, e.g. AT^SISW=9,0,1. 1) If Socket service: Query available data with AT^SISR, e.g. AT^SISR=9,1430. - Close service with AT^SISC, e.g. AT^SISC=9. 1) Please note that in MC55 04.00 the <eodFlag> does not work properly for the Socket service. Therefore, if the Socket service is configured for TCP, check with <unackData> that the transmission buffer is empty, before activating the <eodFlag>. See Release Notes related to MC55 04.00.

For details see description of value 2 for parameter <value> of command AT&C. 2 Allocated Service profile resources are allocated, i.e. at least the service type has been set (parameter <srvParmTag>, value "srvType" of AT^SISS). The service is not opened, but ready for configuration. 3 Connecting State after opening a service with AT^SISO where the connection is being established. If connection setup is successful the service proceeds to the state "4" (Up) and one of the URCs "^SISW" and "^SISR" may follow. If connection setup is not successful, the "^SIS" URC may appear and the service enters <srvState> 6 (Down). In the case of FTP, <srvState>=3 means that the command channel is being established. If the service profile is configured as Socket listener, then the listener always stays at <srvState>=3 and <socketState>=3 (LISTENER), while the <srvState> and <socketState> of the dynamically assigned service profile may change. See examples in Section 10.5.1. MC55_ATC_V04.00 Confidential / Released Page 240 of 475 3/17/06 4 Up The service performs its purpose. The data transfer process is the major function at this state. FTP: Data channel is up. SMTP: The SMTP service will not enter <srvState>=4 until the host has written the first data packet with AT^SISW. 5 Closing Internet Service is closing the network connection. FTP: Command channel is released. 6 Down This state is entered if - the service has successfully finished its session (see note on Socket), - the remote peer has reset the connection or - the IP connection has been closed because of an error.

Note • As in polling mode no error URCs are available you are advised to integrate the commands AT^SISI and AT^SISE into the command sequences for upload and download jobs. So, the AT^SISO command may be followed by AT^SISI to check that the service has entered the <srvState>=4 before sending AT^SISR or AT^SISW. This helps you to detect errors even though the "^SIS" URCs are disabled. A typical example is that the service fails to be opened because the service profile contains a wrong destination address. In such a case, after opening with AT^SISO and OK response, the service quickly enters the states <srvState>=2, 4 and 6, with an error being returned no earlier than after sending the first AT^SISR or AT^SISW command. In URC mode, an error URC, such as "Host not found" would be received in this situation, but in polling mode the only way to detect the state is using AT^SISI or, alternatively, AT^SISO.

The range is determined by <reqReadLength>: If <reqReadLength> was greater than 0, then <cnfReadLength> may be less or equal to the value requested with <reqReadLength>. If <reqReadLength> equals 0 (peek operator) the value indicated by <cnfReadLength> may be greater than 1500. <urcCauseId>(num) Indicates whether or not data is available for reading with AT^SISR. 1 Data is available and can be read by sending the AT^SISR command. The URC appears when less data was confirmed (in <cnfReadLength>) than requested (with <reqReadLength>) during the last "Read Data" operation and new data is available. 2 End of data. Data transfer has completed (all data read). The service can be closed with AT^SISC. <remainUdpPacketLength>(num) Optional third parameter of the AT^SISR write command response displayed only if the Socket service uses UDP. The reception of each datagram must be completed before the next datagram can be received. This may be a problem if the buffer of the host application is limited and not designed to handle the maximum packet size of 1500 bytes. To compensate this, the host is advised to request, via <reqReadLength>, an amount less or equal its maxmimum buffer capacity and wait for the resulting AT^SISR write command response with parameter <remainUdpPacketLength>. The benefit of this approach is that the host may properly receive all parts of a UDP datagram, as after each received data part the number of remaining bytes is synchronized, until reading the datagram is finished. If the currently read datagram is smaller than the number of bytes requested by the host the <remainUdpPacketLength> parameter is omitted. Further write attempts with AT^SISR are denied as long as the <remainUdpPacketLength> is unequal 0 or is not omitted. In this case the service returns "+CME ERROR: operation of service temporary not allowed". 0 Indicates that all bytes of the current UDP datagram are read. 1...(max. data size)-1 Indicates that the currently read UDP datagram is not yet complete. The displayed value is the remaining number of bytes. <remainUdpPacketLength> is unequal 0 until reading all parts of the current datagram is finished. 10.7.1 Example: Socket Host Reads Small Amounts of UDP Data Packets (URC Mode) This section applies only to the Socket service using the UDP protocol. The example shows how to read UDP packets if the buffer of the host application can handle only a few bytes. There are two datagrams available for reading. Buffer size: 6 bytes Datagram A = 18 bytes (content "THIS_IS_DATAGRAM_A") Datagram B = 3 bytes (content "NEW") MC55_ATC_V04.00 Confidential / Released Page 246 of 475 3/17/06 ^SISR: 0,1 at^sisr=0,6 ^SISR: 0,6,12 THIS_I OK at^sisr=0,6 ^SISR: 0,6,6 S_DATA OK at^sisr=0,6 ^SISR: 0,6,0 GRAM_A OK at^sisr=0,6 ^SISR: 0,3 NEW OK MC55_ATC_V04.00 Confidential / Released Service profile 0 is configured for Socket service and UDP. The URC notifies host that data is available for reading. The host requests to read 6 bytes. The first 6 bytes of datagram A are confirmed and transmitted. Another 12 bytes are still available. The host requests to read the next part of 6 bytes. The next 6 bytes of datagram A are confirmed and transmitted. Another 6 bytes are still available. The host requests to read the next part of 6 bytes. Last part of datagram A was received, no remainder is left. Again, the host requests to read 6 bytes. This time, the request refers to datagram B which has only 3 bytes. As the read datagram is smaller than the size requested by the host, the response does not include the <remainUdpPacketLength>. 3 bytes are confirmed and transmitted. Datagram B was properly received. Page 247 of 475 3/17/06 10.8 AT^SISW Internet Service Write Data The AT^SISW command triggers a write operation (upload) and queries the amount of data already sent, but not acknowledged at the TCP layer. The write operation may be run in binary mode, or in interactive text mode. The AT^SISW write command may return the following errors: • "+CME ERROR: operation failed" if there is a problem on application, socket, PPP or GPRS/GSM level. The AT^SISE command and the "^SIS" URC offer additional error information. • "+CME ERROR: operation temporary not allowed" e.g. if the service has not network resources allocated. • "+CME ERROR: operation not allowed" e.g. if the service is not configured. Syntax Test Command AT^SISW=?

The URC is issued when the service is ready to accept new user data. The URC is disabled in polling mode. See AT^SCFG, parameter "Tcp/WithURCs", <tcpWithUrc>. Parameter Description <srvProfileId>(num) <srvProfileId> 0 ... 9 specified with AT^SISS. <reqWriteLength>(num) 0...1500 Specifies the number of bytes to be sent with AT^SISW or, if set to 0, requests the amount of data already sent with AT^SISW but not yet acknowledged: • Parameter <reqWriteLength> may be 1...1500 bytes to specify the amount of data to be sent with AT^SISW. • If parameter <reqWriteLength> equals 0, AT^SISW does not expect any data, but a normal query is perfomed. This allows the application to explictly request, in particular at the end of an upload job, the amount of unacknowledged data at the TCP layer indicated by <unackData>. • In interactive text mode, <reqWriteLength> must be set to any value greater than 0 (but not necessarily the precise number of bytes). If set to 0 in interactive text mode, <reqWriteLength> would be interpreted as query for unacknowledged data and, thus, prevent data transfer. MC55_ATC_V04.00 Confidential / Released Page 248 of 475 3/17/06 • If Socket service is selected with UDP protocol - <reqWriteLength>=0 can be used to send an empty UDP packet; - the maximum requestable write size specified via <reqWriteLength> is limited to 1460 bytes. Any attempt to write more bytes will be denied and causes the following URC to appear: "^SIS: <id>, 0, 9, The supplied buffer was too small / large". <eodFlag>(num) End of data indication flag. Parameter is ignored for HTTP. [0] No end of data. Other data may follow to be transmitted via the Internet service. 1 End of data is signalled to the Internet Service. Further AT^SISW write commands return an error response. However, reading data may be possible. The <eodFlag> is effective only if the <reqWriteLength> equals <cnfWriteLength>, in particular if the <reqWriteLength> equals 0. If <mode> equals 1 the <eodFlag> is effective only if the write operation has been finished with CTRL-Z. <mode>(num) Control how the application provides the data bytes to be sent. [0] Binary mode This mode allows sending a number of bytes defined with parameter <reqWriteLength>. 1 Interactive text mode This mode allows the user to type and send 8-bit ASCII characters while the service is open. Ctrl-Z terminates data input and causes the data to be transferred. Interactive text mode requires that the <reqWriteLength> is set to any value greater than 0 (though it is not necessary to specify the precise number of bytes). In this case the <cnfWriteLength> parameter indicates the maximum length of the data stream without control character CTRL-Z. The <txCount> counter is incremented only by the portion of data actually transmitted. In interactive text mode, the following characters are defined as control codes: • BACKSPACE ("\x08") deletes the last given character, • CTRL-Z ("\x1a") terminates the input, • ESC ("\x1b") aborts the command. An <eodFlag> is ignored in this case. The V.25 command ATE also controls the echo mode of the interactive text mode. If echo is enabled (ATE1) all characters are echoed until <cnfWriteLength> is reached. Any attempt to input further data ends up with the warning message 4001 indicated after the data stream has been completed with CTRL-Z, nevertheless all data within the range of <cnfWriteLength> will be sent. See also Section 10.10, Internet Service URC "^SIS". ATE0 disables the echo mode generally. <cnfWriteLength>(num) 0...1500 MC55_ATC_V04.00 Confidential / Released Confirmed number of data bytes which can be transmitted via the Internet service configured in <srvProfileId>. In binary mode (see <mode>) this number may be less or equal to the value requested with <reqWriteLength>. The application has to deliver exactly the number of bytes indicated by <cnfWriteLength>. A 0 value means that no data can be written at this time, i.e. it serves as a flow control mechanism. In interactive text mode, <cnfWriteLength> indicates the maximum number of bytes it can process. Characters above the indicated number are ignored. Page 249 of 475 3/17/06 <unackData>(num) Number of data bytes already sent but not yet acknowledged at the TCP layer. The value is constantly changing until the entire upload job has completed. If the value equals 0 all data sent so far is acknowledged. In binary mode, <unackData> includes the <cnfWriteLength> value of the pending write operation. Therefore, the very first write operation of an upload job returns identical values for <cnfWriteLength> and <unackData>. This mechanism allows the host application to easily verify whether or not the remote host has successfully received the data. Parameter is not applicable to HTTP, POP3, SMTP and Socket UDP client. For these services the counter is always set to 0. <urcCauseId>(num) 1 The service is ready to accept new user data. 2 Data transfer has been finished successfully and Internet service may be closed without loss of data. Notes • The AT^SISW write command must be terminated only with the ASCII character set with ATS3. The factory default for S3 is #13 (Carriage Return). Do not send any further characters after the S3 end-of-line identifier, until the response "^SISW" is received. This is necessary to avoid that any characters related to the AT command can be interpreted as being part of the data stream to be transferred. Also refer Section 1.4, AT Command Syntax. • If the Socket service is configured for UDP and fixed size and the interactive text mode is active, the PDU length always equals the specified fixed length. If the input characters exceed the specified fixed length, then all surplus characters will be ignored. If the input characters are less than the specified fixed length, then the remaining range will be filled with "\0" bytes. 10.8.1 Usage of parameter <eodFlag> Service type Socket After the service accepts the end-of-data flag the service state changes to "Closing". No further user data is accepted. After releasing the TCP link the service remains in state "Down". FTP Parameter only applicable for FTP upload session. After accepting the end-of-data flag the service state changes to "Closing" and starts to end the running FTP session. No further user data is accepted. After the FTP session is completed on FTP protocol level the service state switches to "Down". In case of successful completion the URC "^SISW: x,2" is generated. SMTP SMTP service sends some "closing" commands to the SMTP server which are necessary to mark the email as successfully sent on the server. The service enters "Closing" state and remains in it until the final protocol exchange with the SMTP server has been completed. The "OK" response following AT^SISW indicates that the SMTP service has accepted the last data - IT DOES NOT indicate the successful completion of the SMTP service. Successful completion will be indicated either by the appropriate URC "^SISW:x,2" or due to the fact that the SMTP service state changes to "Down" state without any error. HTTP / POP3 Parameter not applicable, i.e. value is ignored. MC55_ATC_V04.00 Confidential / Released Page 250 of 475 3/17/06 10.9 AT^SISE Internet Service Error Report The AT^SISE write command returns the current error status of the specified Internet service profile. If the service profile is not defined or the value is invalid "+CME ERROR" response is returned. The error status is identical to the content of the "^SIS" URC last issued. If a service fails the commands AT^SISR or AT^SISW will return an error response. However, if the AT^SISE command returns <infoID>=0 it is recommended to use the AT+CEER command because a general GSM/ GPRS problem might be the reason. Syntax Test Command AT^SISE=?

The second part consists of tables listing the information elements delivered within the "^SIS" URC and the command response of AT^SISE. The presentation of the "^SIS" URC containing the parameter <urcCause>=0 can be disabled or enabled depending on whether polling mode or URC mode is preferred. To do so, use the AT^SCFG command, parameter "Tcp/WithURCs" (refer to <tcpWithUrc>). However, if related to <urcCause>=1 or 2, the "^SIS" URC will always be delivered regardless of the setting made with AT^SCFG. Unsolicited Result Code Indicates an event, an error or an information element. The same information can be obtained via AT^SISE. ^SIS: <srvProfileId>, <urcCause>[, [<urcInfoId>][, <urcInfoText>]] The URC may appear if an event or an error occurs, for example after opening an Internet service with AT^SISO or any time during operation. The URC also indicates a request for a mobile terminated Internet service client connection, or a failure if a mobile terminated request is rejected. Furthermore, the URC may deliver an information element resulting from a specific command given in the service profile. A list of possible causes can be found in the tables below. The tables contain the <urcInfoId> and, if applicable, a specific <urcInfoText>. If marked with *) the precise text related to a <urcInfoId> varies greatly depending on the scenario and the implementation of the remote server. In these cases, only a brief explanation of the scenario can be found in the table column "Description". Parameter Description <urcCause>(num) URC cause identifier. 0 An event has occurred after opening or while using an Internet service. The event number is presented via <urcInfoId> and may be an error, a warning, an information element or a note. Optionally additional information may be supplied via <urcInfoText>. 1 Indicates that an opened Socket listener service is receiving a connection request from a remote client. The incoming socket connection is dynamically assigned to the next free Internet service profile. In this case, the parameter <urcInfoId> inside the "^SIS" URC equals the <srvProfileId> of the dynamically assigned service profile. This ID shall be used to accept the connection request with AT^SISO or to reject it with AT^SISC. The connection status may be requested by using the AT^SISI read or write command or the AT^SISO read command. Among other details, the response indicates the IP address of the remote client (parameter <remAddr>). This may be helpful to decide whether to accept or reject the request. 2 Incoming Socket service client connection has failed. The client request was rejected automatically because no free Internet service profile was available. <urcInfoId>(num) Information identifier related to <urcCause>. See tables below for further detail. The <urcInfoId> number ranges indicate the type of information element: 0: Service is working properly. 1 - 2000: Error, service is aborted and enters <srvState>=6 (Down). 2001 - 4000: Information related to progress of service. 4001 - 6000: Warning, but no service abort. 6001 - 8000: Notes Additional information for Socket service: As stated above, if a Socket connection request from a remote client is received (see <urcCause>=1) the <urcInfoId> equals the <srvProfileId> of the dynamically assigned free service profile.

URC mode is enabled (delivery detault). at^scfg=tcp/withurcs ^SCFG: "Tcp/WithURCs","on" OK at^scfg=tcp/withurcs,off ^SCFG: "Tcp/WithURCs","off" OK 10.11.2 Select polling mode (by switching off URC mode). Polling mode is accepted. Configuring Socket Listener The example assumes that a connection profile has been created as explained in Section 10.1.1 or Section 10.1.2. Keep in mind that if the host is configured as listener another service profile must be left free to be dynamically assigned as Server when the listener receives a connection request from a remote client. Configure the service profile 4 for use as Socket listener: at^siss=4,srvType,socket OK at^siss=4,conId,0 OK at^siss=4,address,"socktcp://listener:65534" Select service type Socket. Select connection profile 0. The host specifies its local port 65534 to be used for the Socket listener service. The local IP address will be dynamically assigned when the service is opened with AT^SISO. OK Open the Socket service and query the IP address dynamically assigned to the Socket listener: at^siso=4 OK at^siso? ^SISO: 0, "" ^SISO: 1, "" ^SISO: ^SISO: ^SISO: ^SISO: ^SISO: ^SISO: ^SISO: OK 2, 3, 4, 6, 7, 8, 9, Open the Socket service.

GPRS Commands This chapter describes AT Commands that a TE (Terminal Equipment, e.g. an application running on a controlling PC) may use to control the MC55 acting as GPRS Mobile Termination (MT). Please use chapter "Using GPRS AT commands (Examples)" as a first guidance. 11.1 AT+CGACT PDP context activate or deactivate Syntax Test Command AT+CGACT=? Response(s) +CGACT: (list of supported <state>s) OK Read Command AT+CGACT? Response(s) +CGACT: <cid>, <state> [+CGACT: <cid>, <state>] ... OK Write Command AT+CGACT=[<state>[, <cid>[, <cid>]]] Response(s) OK ERROR +CME ERROR Reference(s) PIN GSM 07.07 % ASC0 ASC1 % % MUX1 MUX2 % % MUX3 Charge % ! ! Last ! Command Description The test command is used for requesting information on the supported PDP context activation states. The read command returns the current activation states for all the defined PDP contexts. The write command is used to activate or deactivate the specified PDP context(s). After the command has completed, the MT remains in V.250 command state. If any PDP context is already in the requested state, the state for that context remains unchanged. If the MT is not GPRS attached when the activation form of the command is executed, the MT first performs a GPRS attach and then attempts to activate the specified contexts. If no <cid>s are specified the activation/deactivation form of the command activates/deactivates all defined contexts. If the MT is not able to activate a context because of a failed attach, the command returns "ERROR" or "+CME ERROR: unknown" after 385 seconds (timer T3310 expired). If the MT is attached but is not able to activate a context for more than 160 seconds (timer T3380 expired), command returns "ERROR" or "+CME ERROR: unspecified GPRS error. In this case AT+CEER returns "+CEER: 51,3,0". The command should not be used to deactivate a PDP context during the implicit PDP context deactivation procedure which is started automatically after LCP termination or by dropping the DTR line (if AT&D2 is configured). For details refer to Section 11.6.1, Automatic deactivation of PDP context during dial-up PPP. MC55_ATC_V04.00 Confidential / Released Page 266 of 475 3/17/06 Parameter Description <state>(num) Indicates the state of PDP context activation. 0 deactivated [1] activated <cid>(num) PDP Context Identifier is a numeric parameter which specifies a particular PDP context definition. The parameter is local to the TE-MT interface and is used in other PDP context related commands. 1...2 Notes • ATH will deactivate any PDP context. • If the MT is in dedicated mode, the write command returns "+CME ERROR: operation temporary not allowed". • A maximum of 2 contexts can be activated at the same time, no matter on which interface. Trying to activate more than 2 contexts will cause "+CME ERROR: operation temporary not allowed". Note that, depending on the provider, the number of activated contexts may be further restricted. In such cases "+CME ERROR: unspecified GPRS error" will be returned and AT+CEER returns "+CEER: 50,26,0". Remember that contexts may be activated implicitly by using the ATD*98# or ATD*99# GPRS compatibility commands without specifying a <cid>. • If an activated context will be deactivated without using the command AT+CGACT, then the result code "NO CARRIER" will be issued to indicate the context deactivation. This happens for example if the context deactivation is forced by the network or if deactivation results from a network deregistration with AT+COPS=2.

Last ! % Command Description The write command requests the MT to respond to a network request for GPRS PDP context activation which has been signaled to the TE by the RING or CRING unsolicited result code. The <response> parameter allows the TE to accept or reject the request. Parameter Description <response>(num) [0] the request is rejected and the MT returns OK to the TE 1 accept and request that the PDP context be activated <L2P>(str) a string parameter which indicates the layer 2 protocol to be used (see AT+CGDATA command) <cid>(num) a numeric parameter which specifies a particular PDP context definition (see AT+CGDCONT command). Note • If <response> is 1, the following procedure is followed by the MT: If the <L2P> parameter value is unacceptable to the MT, the MT will return an ERROR or +CME ERROR response. Otherwise, the MT issues the intermediate result code CONNECT and enters V.250 online data state. A <cid> may be specified for use in the context activation request. During the PDP startup procedure the MT has the PDP type and the PDP address provided by the network in the Request PDP context activation message. If this is in conflict with the information provided by a specified <cid>, the command will fail. There will be no conflict, if the PDP type matches exactly and the PDP address given by the context definition for <cid> is empty or matches exactly with the address specified with the network PDP context activation message. The context will be activated using the values for PDP type and address provided by the network, together with all other information found in the PDP context definition. An APN may or may not be required, depending on the application. MC55_ATC_V04.00 Confidential / Released Page 268 of 475 3/17/06 If no <cid> is given or if there is no matching context definition, the MT will attempt to activate the context using the values for PDP type and address provided by the network. The other parameters will be set to their default values (see AT+CGDCONT). If activation is successful, data transfer may proceed. After data transfer is complete, and the layer 2 protocol termination procedure has completed successfully, the V.250 command state is reentered and the MT returns the final result code OK. In the event of an erroneous termination or a failure to start up, the V.250 command state is re-entered and the MT returns the final result code NO CARRIER, or if enabled, +CME ERROR. Attach, activate and other errors may be reported. It is also an error to issue the AT+CGANS command when there is no pending network request. The command may be used in both normal and modem compatibility modes.

Command Description The test command is used for requesting information on the supported GPRS service states. The read command returns the current GPRS service state. The write command is used to attach the MT to, or detach the MT from the GPRS service. After the command has completed, the MT remains in V.250 command state. If the MT is already in the requested state, the command is ignored and the OK response is returned. Any active PDP contexts will be automatically deactivated when the attachment state changes to detached. If the MT is not able to attach for more than 5 minutes, command returns "ERROR" or "+CME ERROR: unknown", but MT is still trying to attach. If the MT is not able to detach for more than 1 minute, command returns "ERROR" or "+CME ERROR: unknown", but MT is still trying to detach. If an attach is issued during a running detach, command returns "ERROR" or "+CME ERROR: unspecified GPRS error". Parameter Description <state>(num) Indicates the state of GPRS attachement. 0(P) detached [1] attached Notes • If the MT is in dedicated mode, write command returns "+CME ERROR: operation temporary not allowed". • When the module is GPRS attached and a PLMN reselection occurs to a non-GPRS network or to a network where the SIM is not subscribed to for using GPRS, the resulting GMM (GPRS mobility management) state according to GSM 24.008 is REGISTERED/NO CELL, meaning that the read command will still show <state>=1.

Command Description The test command returns the values of <n> supported by the MT as a compound value. The write command disables or enables an automatic positive response (auto-answer) to the receipt of a Request PDP Context Activation message from the network. It also provides control over the use of the V.250 basic commands ATS0, ATA and ATH for handling network requests for PDP context activation. Parameter Description <n>(num) 0 Disable automatic response for network requests for GPRS PDP context activation. GPRS network requests are manually accepted or rejected by the AT+CGANS command. 1 Enable automatic response for network requests for GPRS PDP context activation. GPRS requests are automatically accepted according to the description below. 3(&F)(P) Modem compatibility mode. The automatic acceptance of both GPRS and incoming CSD calls is controlled by the ATS0 command. Manual control uses the ATA and ATH commands, respectively, to accept or reject GPRS network requests or incoming CSD calls. Notes • It is allowed to have different AT+CGAUTO settings on different interfaces. • When the AT+CGAUTO=0 command is received, the MT will not perform a GPRS detach if it is attached. Subsequently, when the MT announces a network request for PDP context activation by issuing the URC RING or CRING, the TE may manually accept or reject the request by issuing the AT+CGANS command or may simply ignore the network request. MC55_ATC_V04.00 Confidential / Released Page 271 of 475 3/17/06 • When the AT+CGAUTO=1 command is received, the MT will attempt to perform a GPRS attach if it is not yet attached. Failure will result in ERROR or, if enabled +CME ERROR being returned to the TE. Subsequently, the MT announces a network request for PDP context activation by issuing the URC RING to the TE, followed by the intermediate result code CONNECT. The MT then enters V.250 online data state and follows the same procedure as it would after having received a +CGANS=1 with no <L2P> or <cid> values specified. • If a GPRS attach will be initiated by this command and the MT is not able to attach for more than 385 seconds (timer T3310 expired), command returns with "ERROR" or "+CME ERROR: unknown", but MT is still trying to attach and the requested automatic mode <n> is in use. • If a network request for PDP context activation is answered automatically and if another AT command is issued at the same time on the same interface, then this AT command is not executed. Any response belongs to the automatic context activation procedure. If the AT command which caused the collision was a circuit switched data call, the CONNECT response does not belong to this data call but to the GPRS. This can be detected if ATX is not set to 0. CS data call will issue CONNECT <text>, GPRS will issue CONNECT only.

Last % Command Description The test command is used for requesting information on the supported layer 2 protocols to be used between the TE and MT. The write command causes the MT to perform all actions which are necessary to establish communication between the TE and the network using one or more GPRS PDP types. This may include performing a GPRS attach and one or more PDP context activations. Commands following the AT+CGDATA command in the AT command line will not be processed by the MT. If no <cid> is given or if there is no matching context definition, the MT will attempt to activate the context with PDP type IP and all other context parameters set to their default values (see AT+CGDCONT, AT+CGQREQ, AT+CGQMIN). If the <L2P> parameter is omitted, the layer 2 protocol is unspecified and PPP will be used. If the write command is successful, the MT issues the intermediate result code CONNECT and enters V.250 online data state. After data transfer is complete, and the layer 2 protocol termination procedure has completed successfully, the command state is reentered and the MT returns the final result code OK. If the <L2P> parameter value is unacceptable to the MT, the MT returns ERROR or +CME ERROR. In the event of erroneous termination or a failure to start up, the command state is reentered and the MT returns NO CARRIER, or if enabled +CME ERROR. Parameter Description <L2P>(str) Layer 2 protocol to be used between the TE and MT. ["PPP"] layer 2 protocol PPP <cid>(num) Parameter specifies a particular PDP context definition. The parameter is local to the TE-MT interface and is used in other PDP context-related commands. 1...2 MC55_ATC_V04.00 Confidential / Released Page 275 of 475 3/17/06 Notes • If the MT is in dedicated mode, write command returns "+CME ERROR: operation temporary not allowed". • It is possible to leave the GPRS data mode and enter the command mode by using the V.250 command +++. By using the command AT+CGDATA again, the data mode is reentered. Which context is used to return to data mode, depends on the supplied parameter <cid>. If no <cid> is specified, this is equivalent to using the V.250 command ATO, which is usable for GPRS connections too. In this case the first context will be used, which is active and already in data mode since it has been activated (the internal context used for GPRS connection without explicitly specifiying a context identifier has the highest priority). It is possible to use AT+CGDATA to enter the data mode for a context, which is not yet in data mode since it has been activated. With ATO this is not possible. 11.6.1 Automatic deactivation of PDP context during dial-up PPP When using the AT+CGDATA write command or ATD*99# or ATD*98# the MT issues the intermediate result code CONNECT and enters V.250ter online data state. In V.250 online data state, first some LCP protocol exchange between MT and TE is performed to set up the PPP link. After successfully establishing the PPP link, the MT performs the PDP context activation procedure if the context is not already activated. As a result, the MT is in a "PDP context activated" state within the PLMN, the PPP link is established on the mobile side and the mobile is ready for IP data transfer. If the TE wants to close the LCP link the MT may perform an LCP termination request procedure on PPP level. After this LCP termination procedure the MT deactivates the PDP context automatically and the MT returns to V.250 command mode and issues the final result code NO CARRIER. During the implicit PDP context deactivation procedure after LCP termination the TE may change into V.250 command state (e.g. by using +++ or by toggling DTR if AT&D is set to 1) before the result NO CARRIER occurs. In this case the application should not try to deactivate the PDP context by using the commands AT+CGACT or ATH. If DTR is configured to disconnect data connections (AT&D2), then the application should not toggle DTR during the implicit PDP context deactivation and before "NO CARRIER" is received.

See also "3GPP TS 27.007 (GSM 07.07): AT command set for User Equipment (UE)". When the ATS0=<n> (<n> > 0) command is received, the MT will attempt to perform a GPRS attach if not yet attached and if configured to do so (see AT^SCFG, parameter <gs0aa>). Subsequently, the MT will announce a network request for PDP context activation by issuing the URC RING or CRING to the TE, followed by the intermediate result code CONNECT. The MT then enters V.250 online data state and follows the same procedure as it would after receiving a AT+CGANS=1 command with no <L2P> or <cid> values specified. ATS0=0 does not perform an automatic GPRS detach. Syntax Read Command ATS0?

Notes • If different settings are used on each interface, and a request for PDP context activation is received, the interface 'wins' which is idle and uses the smallest ATS0 value. • When a network request for PDP context activation is answered automatically and another AT command is issued at the same time on the same interface then this AT command will not be executed. Any response relates to the automatic context activation procedure. If the AT command which caused the collision was a CS data call, the CONNECT response does not pertain to this data call but to GPRS. This can be detected if ATX is not set to 0. The CS data call will issue CONNECT <text>, GPRS will issue CONNECT only. • A network request for PDP context activation has a maximum duration of approximately 40 seconds (for details see GSM 04.08). A RING/CRING URC is issued every 5 seconds, so setting parameter <n> to values greater than 7 will not allow a successful context activation and is not recommended. • Automatic GPRS attach will not be performed on recalling a stored user profile with ATZ or on power-up, even though a value <n> greater than 0 was stored in the user profile with AT&W. • If AT^SCFG="GPRS/ATS0/withAttach","on" is selected, but the automatic GPRS attach attempt fails (e.g. the network rejects the attach request), the ATS0 write command ends up with "ERROR" or "+CME ERROR: unknown" after approx. 5 minutes, though the new <n> value takes effect. This is necessary because ATS0 is used for circuit switched calls too. • ATS0 write command is PIN protected.

The QoS consists of - the precedence class - the delay class - the reliability class - the peak throughput class - the mean throughput class and is divided in "requested QoS" and "minimum acceptable QoS". All parameters of the QoS are initiated by default to the "network subscribed value (= 0)" but the QoS itself is set to be undefined. To define a QoS use the AT+CGQREQ or AT+CGQMIN command. Overwrite the precedence class of QoS of CID 1 and set the QoS of CID 1 to be present: AT+CGQREQ=1,2 OK A following read command will respond: AT+CGQREQ? +CGQREQ: 1,2,0,0,0,0 OK All QoS values of CID 1 are set to network subscribed now, except precedence class which is set to 2.

If no CID and no STATE is given, all defined CIDs will be activated by: AT+CGACT= OK If no CID is defined the mobile responds +CME ERROR: invalid index Remark: If the mobile is NOT attached by AT+CGATT=1 before activating, the attach is automatically done by the AT+CGACT command. After defining and activating a CID it may be used to get online by: AT+CGDATA="PPP",1 CONNECT AT+CGDATA= CONNECT The mobile is connected using the parameters of CID 1. The mobile is connected using default parameters (<L2P>="PPP" and <cid> as described for command AT+CGDATA). The mobile supports Layer 2 Protocol (L2P) PPP only. Remark: If the mobile is NOT attached by AT+CGATT=1 and the CID is NOT activated before connecting, attaching and activating is automatically done by the AT+CGDATA command. Some providers (e.g. Vodafone or E-Plus) require to use an APN to establish a GPRS connection. So if you use the Microsoft Windows Dial-Up Network and ATD*9... to connect to GPRS you must provide the context definition as part of the modem definition (Modem properties/Connection/Advanced.../Extra settings).

Incoming SMs or Status Reports have to be acknowledged with AT+CNMA=0 when using these phase 2+ parameters. • Requirements specific to Multiplex mode: In multiplex mode (AT+CMUX=0) only one channel can use a phase 2+ parameter. The parameter for <mt> and <ds> on the other channels have to be set to zero. If either a SM or a Status Report is not acknowledged, all AT+CNMI parameter in all channels will be set to zero. • If the ME operates on different instances (MUX channels 1, 2, 3 or ASC0/ASC1) avoid different settings for routing and indicating short messages. For example, if messages shall be routed directly to one instance of the TE (set with AT+CNMI, AT^SSDA), it is not possible to activate the presentation of URCs with AT+CMER or AT+CNMI on another instance. Any attempt to activate settings that conflict with existing settings on another interface, will result in CME ERROR, or accordingly CMS ERROR. • Handling of Class 0 short messages: If the host application is provided with a display and AT^SSDA=1 has been set Class 0 short messages can be displayed immediately. If the host application does not include a display, ME handles Class 0 short messages as though there was no message class, i.e. it will ignore bits 0 and 1 in the <dcs> and normal rules for exceeded memory capacity shall apply. This approach is compliant with GSM 03.38 . • The parameters <ra> and <tora> will only be displayed if <ra> of the AT^SSCONF command is set to 1. • If either a SM or a Status Report is not acknowledged, all AT+CNMI parameter in all channels will be set to zero.

The indices <index> of the ''MT'' storage are dependent on the order selected with AT^SSMSS • The <mem1>, <mem2> and <mem3> parameter will be stored in non-volatile memory. • The user should be aware that the setting ''MT'' involves ''ME'' and ''SM'', with ''ME'' being filled up first. If the ''ME'' storage is full, MC55 will proceed with the ''SM'' storage. Incoming Class 1 short messages (ME specific) will be preferably stored to ''ME'' and may be transferred to the ''SM'' storage if ''ME'' is used up. Incoming Class 2 messages (SIM specific) will be stored to the SIM card only, no matter whether or not there is free ''ME'' space. As a result, the ^SMGO: 2 indication (see AT^SMGO) may be presented without prior indication of ^SMGO: 1. For more information regarding SIM and ME specific message classes refer to <dcs> and the following specifications: GSM 03.38 and 3GPP TS23038. • When <mem3> is switched over from ''MT'' to ''SM'' all free ''ME'' locations will be filled with dummy short messages. This procedure can take up to 35 seconds, until all the 25 records are written. If switching from ''MT'' to ''SM'' was not finished due to error or user break, the value of <mem3> remains ''MT'', but some of the dummy records remain in the ''ME'' storage. These records have to be deleted manually. When <mem3> equals ''SM'', do not delete the dummy messages in the ''ME''. storage. They will be automatically deleted when you switch back from ''SM'' to ''MT''. Again, this may take up to 35 seconds. If switching from ''SM'' to ''MT'' was not finished due to an error or user break, the value of <mem3> remains ''SM'', but the ''ME'' storage will no longer be filled with dummy records. New incoming short messages may now be written to the ''ME'' storage, if ''SM'' is already full. To avoid this, repeat the AT+CPMS command as soon as possible to switch <mem3> back to ''MT''. As an alternative, you can manually delete the dummy records and issue AT+CPMS=MT,MT,MT. • Multiplexer: In Multiplex mode or when the two physical serial interfaces are connected, the parameter <mem3> will be the same on all instances, but the settings of <mem1> and <mem2> may vary on each channel / interface. As a result, changes on parameter <mem1> and/or <mem2> befor activating the multiplexer or differences values for other instanes can result in not desired behaviours like different outputs for AT+CMGL and so on. • While <mem3> equals ''SM'' and <mem1> equals ''ME'' it is possible that, after deleting short messages from ''ME'', the freed space on ''ME'' is reclaimed for new incoming short messages, when there is no space left on the ''SM'' storage. As it is often the clients concern to have received short messages stored only to the SIM card, inconsistent settings should be generally avoided. This can be achieved simply by using the same parameter for all memory indices. • Users should be aware that when using this AT command quickly after SIM PIN authentication the SIM data may not yet be accessible, resulting in a short delay before the requested AT command response is returned. See Section 20.1, Restricted access to SIM data after SIM PIN authentication for further detail. • The indices <index> of the storage are dependent on the order selected with AT^SSMSS.

SIM related Commands The AT commands described in this chapter are related to the Subscriber Identity Module (SIM) connected to MC55. Note: If using data from the SIM please bear in mind that the content of all Elementary Files is subject to change at any moment! This is true because the network can change the SIM's data in the background via the SIM Application Toolkit (SAT) procedure "Data download to SIM". For a detailed description please refer to GSM 11.14, [22]. To get informed that changing Elementary Files has taken place the TA needs to hook to the SAT Proactive Command "REFRESH". To achieve this, the AT command interface of SAT, i.e. Remote-SAT, needs to be activated. An overview is given at Chapter 15., SIM Application Toolkit (SAT) Commands, additional information is available with the document "Remote-SAT User Guide" [4]. 14.1 AT+CRSM Restricted SIM Access AT+CRSM offers easy access of the Elementary Files on the SIM. Access to the SIM database is restricted to the commands which are listed at <command>. However, additional SIM commands are available via AT^SXSM. All parameters of AT+CRSM are used as specified by GSM 11.11 [21]. MC55 handles internally all required SIM interface locking and file selection routines. As response to the command, the MC55 sends the actual SIM information parameters and response data. Error result code "+CME ERROR" may be returned if the command cannot be passed to the SIM, e.g. if the SIM is not inserted. However, failure in the execution of the command in the SIM is reported in <sw1> and <sw2> parameters.

SIM Application Toolkit (SAT) Commands This chapter offers a brief reference of commands and responses related to the MC55's SIM Application Toolkit (SAT) implementation. Detailed information is available with the document "Remote-SAT User Guide" [4]. Please contact the Wireless Modules Application Engineering Department at Siemens AG for details. ETSI specification GSM 11.14 [22] defines SAT in detail. SAT allows for the execution of applications provided by a Subsciber Identity Module (SIM). Usually SIM cards are used for storing GSM network provider and user specific data, e.g. phonebook entries and Short Messages (SMS). However, a SIM card may also hold a SIM Application. Since the MC55 has SAT functionality it is able to execute the commands issued by applications implemented on a network provider specific SIM card. Two groups of commands are used between the ME and the SIM Application: • Proactive Commands are issued to the MC55's SAT from the SIM Application, such as "DISPLAY TEXT". • Envelope Commands are responded to the SIM Application from the MC55, such as "MENU SELECTION". 15.1 AT^SSTA SAT Interface Activation Syntax Test Command AT^SSTA=?

ASC0 ASC1 % % MUX1 MUX2 % % MUX3 Charge % ! ! Last ! Command Description The read command can be used to request the current operating status and the used alphabet of the RemoteSAT interface. The write command is used to activate the AT command interface of the SIM Application Toolkit in the MC55 and needs to be issued after every power on. However, removing and inserting the SIM does not affect the activation status. SAT commands which are not using the AT interface (non MMI related SAT commands , e.g. PROVIDE LOCAL INFORMATION) could be executed without activating Remote-SAT. MC55_ATC_V04.00 Confidential / Released Page 376 of 475 3/17/06 Parameter Description <state>(num) MC55 Remote-SAT interface states 0 RESET 1 OFF 2 IDLE 3 PAC 4 WAIT <Alphabet>(num) 0 GSM character set Input of a character requests one byte, e.g. "Y". 1 UCS2 To display the 16 bit value of characters represented in UCS2 alphabet a 4 byte string is required, e.g. "0059" is coding the character "Y". For details please refer to ISO/IEC 10646. <allowedInstance>(num) 0 SAT is already used on another instance (logical channel in case of the multiplex protocol). Only test and read commands can be used. 1 SAT may be started on this instance via the write version of this command. <SatProfile>(str) SAT profile according to GSM 11.14 [22]. The profile tells the SIM Application which features (e.g. proactive commands) are supported by the SIM Application Toolkit implementation of the MC55. <mode>(num) 1 Activate Remote-SAT Note • To limit the time Remote-SAT is kept in states PAC or WAIT any ongoing (but unanswered) Proactive Command is automatically aborted after 10 minutes with Terminal Response "ME currently unable to process command" or "No response from user" if applicable. An URC "Terminate Proactive Command" will be send to the external application in this case, too. MC55_ATC_V04.00 Confidential / Released Page 377 of 475 3/17/06 15.2 ^SSTN SAT Notification Unsolicited Result Codes URC 1 Proactive Command notification ^SSTN: <cmdType> Every time the SIM Application issues a Proactive Command, via the ME, the TA will receive a notification. This indicates the type of Proactive Command issued. AT^SSTGI must then be used by the TA to request the parameters of the Proactive Command from the ME. Upon receiving the ^SSTGI response from the ME, the TA must send AT^SSTR to confirm the execution of the Proactive Command and provide any required user response, e.g. a selected menu item. URC 2 Terminate Proactive Command notification ^SSTN: <cmdTerminateValue> When the SIM application has issued a Proactive Command to the ME, it is possible that this command will be terminated later. URC "^SSTN" is sent with a different Proactive Command type number (added terminate offset 100) to indicate the termination of the specified command. The state changes to idle. Therefore the TA should avoid sending any further commands related to the terminated Proactive Command, e.g. AT^SSTGI or AT^SSTR. URC 3 Notification that SIM Application has returned to main menu ^SSTN: 254 Notification to the TA when the SIM Application has finished a command cycle and again enters its main menue, which was transferred with an URC "^SSTN: 37" (SET UP MENU) at start up. This URC should be used to open this menue on the sreen. The TA does not need to respond directly, i.e. AT^SSTR is not required. URC 4 SIM reset notification ^SSTN: 255 Notification to the TA if a Proactive Command "REFRESH - SIM Reset" has been issued by the SIM Application, please refer to AT^SSTGI. This URC should be used to set the TAs application to its initial state since the SIM Application will start from the beginning, too. The TA does not need to respond directly, i.e. related AT^SSTGI and AT^SSTR are neither required nor allowed. Since the ME is still busy on SIM access the ME may respond with "+CME ERROR: SIM blocked" or "+CME ERROR: SIM busy" on following PIN required AT Commands for a while. Then TA shall retry until the ME responds with "OK". The time needed for this process depends on the SIM and may take more than 10 seconds. Parameter Description <cmdType>(num) Proactive Command number <cmdTerminateValue>(num) Defined as <cmdType> + terminate offset. The terminate offset equals 100.

Phonebook Commands The AT commands described in this chapter allow the external application to access the phonebooks located in the MC55's memory or on the attached Subscriber Identity Module (SIM). 16.1 Sort Order for Phonebooks Due to the support of UCS2 for the <text> part of phonebook entries, the sort order for phonebook records follows the algorithm published as Unicode Technical Standard #10, "Unicode Collation Algorithm". A memory-optimized version of the proposed collation tables "[AllKeys]" from Unicode Technical Standard #10 is used in order to determine collation weights for Code points between 0000 and 06FF, and composed keys are used for Code points from ranges 0700 to 33FF, A000 to D7FF and E000 to FFFD. Code Points not referenced in these tables will be assigned a default collation weight with their unicode value as level 1 weight. Decomposition is not supported. Phonebook entries whose names contain only characters from the GSM07.07 default alphabet are converted internally into their UCS2 equivalents in order to achieve consistent sorting results. For the user, this means that: • Punctuation marks and other non-alphabetical characters from the common latin-based character sets, and from the standard GSM character set, will be sorted before any alphabetical characters. The ordering in which these marks appear as compared to other non-alphabetical characters from the same group is determined by their collation weights and does not reflect their code values in the UCS2 or GSM alphabet tables above. Please refer to www.unicode.org for detail. • Alphabetical characters from the common latin-based character sets, and from the standard GSM character set, will be sorted according to their underlying base characters, plus the collation weights of their accent signs. • Only collation levels 1 and 2 are regarded, so sorting is not case-sensitive. Example: the european letters "Å" (GSM 0EH, UCS2 00C5h), "æ" (GSM 1DH, UCS2 00E6h), "ç" (GSM09h, UCS2 00E7h), "a" (GSM 61H, UCS2 0061h ) and "b" (GSM 62H, UCS2 0062h) will be sorted in order "a", "Å", "æ" "b","ç" although their numerical values in GSM and UCS2 suggest a different ordering.

The AT+CPBR test command returns the location range supported by the current phonebook storage, the maximum length of <number> field and the maximum length of <text> field. Note: Length information may not be available while SIM storage is selected. If storage does not offer format information, the format list contains empty parenthesizes. The AT+CPBR write command determines the phonebook entry to be displayed with <location1> or a location range from <location1> to <location2>. Hence, if no <location2> is given only the entry at <location1> will be displayed. If no entries are found at the selected location "OK" will be returned. Syntax Test Command AT+CPBR=?

Last ! Parameter Description <location1>(num) The first (lowest) location number within phonebook memory where to start reading. The maximum range supported by the current phonebook is given in the test command response. If <location1> exceeds the upper bound <maxloc> (as indicated by the test command), command will respond with "+CME ERROR: invalid index". <location2>(num) The last (highest) location number within phonebook memory where to stop reading. The maximum range supported by the current phonebook is given in the test command response. If both <location1> and <location2> are in the range indicated by the test command parameter <maxloc>, the list of entries will be output and terminated with "OK". If <location2> exceeds the range indicated by the test command parameter <maxloc>, the list of entries will be output but terminated with "+CME ERROR: invalid index". <number>(str) Phone number in format specified by <type>, it may be an empty string.

Please consider that for types other than 129 or 145 dialing from phonebook with ATD><mem><n> is, depending on the network, not always possible (refer to GSM 04.08 subclause 10.5.4.7 for details). See also <type> of AT+CPBW. Possible values are: 145 Dialing string <number> includes international access code character '+' 161 National number. Network support of this type is optional. 209 Dialing string <number> has been saved as ASCII string and includes nondigit characters other than "*", "#" or "+". Note that phonebook entries saved with this type cannot be dialed. 255 Dialing string <number> is a command to control a Supplementary Service, i.e. "*", "#" codes are contained. Network support of this type is optional. 129 Otherwise <text>(str)(+CSCS) Text assigned to a phone number. The maximum length for this parameter is given with test command response parameter <tlength>. If using an ASCII terminal characters which are coded differently in ASCII and GSM have to be entered via escape sequences as described in Section 1.5, Supported character sets. <maxloc>(num) Maximum location number for the currently selected storage. For phonebooks located on the SIM this value depends on the SIM card type. <nlength>(num) Maximum length of phone number for "normal" locations. Depending on the storage a limited number of locations with extended memory is available per phonebook. These locations allow storing numbers with twice the standard length, which is 2*<nlength> digits for normal numbers, but only <nlength> digits for numbers saved with <type>=209. <tlength>(num) Maximum length of <text> assigned to the telephone number. The value indicated by the test command is given in octets. If <text> is given as GSM characters each character corresponds to one octet. If the <text> string is given in UCS2, the maximum number of characters depends on the coding scheme used for the alpha field of the SIM according to GSM 11.11, Annex B [21]. In the worst case the number of UCS2 characters is at least one less than half the number of GSM characters.

For example, it helps you find entries starting with matching characters. Do not use the serial numbers to dial out or modify entries. • If parameter <RealLocReq>=1 is given by the write command, the response parameter <location> additionally appended to each entry indicates the actual location number. This number can be used for editing with AT+CPBW or dialing with ATD><mem><n>. The first index number of each entry is only the serial number of the sorted list. Before using the AT^SPBG write command it is recommended to query the number of records currently stored in the active phonebook (refer to test command parameter <used>).

Three entries will be displayed at a time. Every time the write command is executed, 3 rows of phonebook records are returned. Each triplet overlaps with the next one. The actual index depends on parameter <value>. This parameter determines whether the index will be increased or decreased. If the index in one output line reaches the last index in the alphabetical list, the next output line will display the first list entry. After the last record of the phonebook has been reached (see parameter <used> for AT^SPBG), the <internal-counter> switches over to the first. There are two ways to use AT^SPBS: • If the optional parameter <RealLocReq> is omitted or (0) the sorted entries will be sequentially numbered. As these numbers are not identical with the location numbers stored in the various phonebooks AT^SPBS can be used for reading only. For example, it helps you find entries starting with matching characters. Do not use the serial numbers to dial out or modify entries. • If parameter <RealLocReq>=1 is given by the write command, the response parameter <location> additionally appended to each entry indicates the actual location number. This number can be used for editing with AT+CPBW or dialing with ATD><mem><n>. The first index number of each entry is only the serial number of the sorted list. See examples below.

To do so, first select the audio mode with AT^SNFS, then activate the audio interface with AT^SAIC and finally enter AT^SNFW to store the settings to your audio profile. To switch back and forth it is sufficient to use AT^SNFS. Syntax Test Command AT^SNFS=? Response(s) ^SNFS: (list of supported <audMode>s) OK Read Command AT^SNFS?

MC55_ATC_V04.00 Confidential / Released Page 418 of 475 3/17/06 Notes • The write command can be used during a voice call to switch back and forth between different modes. This allows the user, for example, to switch handsfree operation (speakerphone) on and off. • Users should be aware that <outStep> is a global setting. This means, when another audio mode is selected during a call, the value of <outStep> does not change. This is also true for mute operation which can be set with AT^SNFM or AT+CMUT: If the microphone is muted and the user selects another audio mode during the call, then the microphone remains muted until explicitly changed. Exception: In audio mode 1 <outStep>=4 is fix. • For use after restart of the module, you are advised to store the selected mode to the audio profile saved with AT^SNFW. Otherwise, audio mode 1 will be active each time the module is powered up. Examples EXAMPLE 1 Suppose a user wishes to use alternatively a handsfree device (speakerphone) and a handset. The handset can be connected to the first analog interface and adjusted to audio mode 4. The handsfree device can be attached to the second analog interface and adjusted to audio mode 2. The factory defaults of AT^SAIC need not be changed. Settings for the handset: AT^SNFS=4 OK AT^SAIC? ^SAIC: 2,1,1 OK Factory default of AT^SAIC assigned to audio mode 4.

Page 420 of 475 3/17/06 17.16 AT^SNFTTY Signal TTY/CTM audio mode capability MC55 offers basic support for equipment using the CTM standard (Cellular Text Telephone Modems). The benefit of CTM is that text characters typed on a TTY device (Text Telephone Type-writer) can be transformed into special audio burst signals for reliable transmission via the existing speech channels of a cellular phone system. If CTM mode is activated, the ME will set the necessary bearer capability bit on outgoing (mobile originated) calls and incoming calls with this bearer capability bit set are accepted. The TE needs to decode the special audio burst signals. If CTM mode is disabled, the ME will clear the bearer capability bit on mobile originated calls and incoming calls with the bearer capability bit set are rejected because the MC55 expects that CTM coded speech data cannot be decoded by the TE. Designed to set the module's speech system into CTM mode, the AT^SNFTTY command allows a CTM device to be connected to one of the three audio interfaces of MC55. Traditional TTY devices that do not incorporate CTM functionality can be connected through an external TTY-to-CTM adapter. Related documents: Refer to the relevant standards, such as 3GPP TS 26.226 (ETSI TS 126 226) and 3GPP TS 23.228 (ETSI TS 123 226). 3GPP documentation can be retrieved, for example, from http://www.3gpp.org/ specs/specs.htm. Application Note 22 "Using TTY/CTM equipment" supplies information needed to connect TTY/CTM equipment to the MC55. Requirements for using TTY/CTM features: • TTY/CTM functionality requires audio mode 5 or 6 with all audio parameters set to their factory default. To do so, first enter the AT^SNFS command to select audio mode 5, then use AT^SNFI and AT^SNFO to restore the default values. Alternatively, factory defaults of all audio parameters in audio modes 2 - 6 can easily be set with AT^SNFD. • Depending on which audio interface the CTM device is connected to select the according settings via AT^SAIC.

In the latter case, see execute command for details. The AT^SRTC execute command is intended for testing. It starts to play a melody from the audio output currently selected with AT^SNFS. To deactivate test playback use AT^SRTC again. During test playback, you can enter the write command to select another melody and adjust the volume. Also, you can enter the read command to check the type and volume of the current ring tone, and to view the status of playback (on / off). The test ringing signal cannot be activated when an MTC is ringing (ERROR). Selecting <volume>=0 during the test, immediately stops playback. After this, ring tones will be muted until you change <volume> using the write command. The AT^SRTC write command chooses the type and volume of ring tones. The settings can be changed no matter whether or not the ME is ringing. The selected type and volume are saved in the non-volatile Flash memory and, thus, are retained after Power Down. An exception is <type>=0, that can be entered to quickly mute the tone or melody currently played to indicate an event. <type>=0 only stops immediately the audible ring tone, but does not terminate the URC that indicates the event (for example RING). No permanent settings are changed or saved. Syntax Test Command AT^SRTC=? Response(s) ^SRTC:(list of supported) <type>s, (list of supported) <volume>s OK Read Command AT^SRTC?

In this case, the clock starts with <time>= "02/01/01,00:00:00" upon next power-up. • Each time MC55 is restarted it takes 2s to re-initialize the RTC and to update the current time. Therefore, it is recommended to wait 2s before using the commands AT+CCLK and AT+CALA (for example 2s after ^SYSSTART has been output). MC55_ATC_V04.00 Confidential / Released Page 426 of 475 3/17/06 18.2 AT+CALA Set alarm time The AT+CALA write command can be used to set an alarm time in the ME When the alarm time is reached and the alarm is executed the ME returns an Unsolicited Result Code (URC) and the alarm time is reset to "00/01/ 01,00:00:00". The alarm can adopt two functions, depending on whether or not you switch the GSM engine off after setting the alarm: • Reminder message: You can use the alarm function to generate reminder messages. For this purpose, set the alarm as described below and do not switch off or power down the ME. When executed the message comes as an Unsolicited Result Code which reads "+CALA". • Alarm mode: You can use the alarm function to restart the ME when powered down. For this purpose, set the alarm as described below. Then power down the ME by entering the AT^SMSO command. When the alarm time is reached, the ME will wake up to Alarm mode. To prevent the ME from unintentionally logging into the GSM network, Alarm mode provides restricted operation. Upon wake-up, the ME indicates an Unsolicited Result Code which reads: "+CALA". A limited number of AT commands is available during Alarm mode, for details see Section 20.4, Availability of AT Commands Depending on Operating Mode of ME. The ME remains deregistered from the GSM network. If you want the ME to return to full operation (normal operating mode) it is necessary to restart the ME by driving the ignition line (IGT pin of application interface) to ground. If your ME is battery powered note that the battery can be charged while the ME stays in Alarm mode. For details please refer to [2]. The AT+CALA test command returns the supported array index values <n>, the supported alarm types <type> and the maximum length of the text <tlength> to be output. The AT+CALA read command returns the current alarm settings in the ME. Syntax Test Command AT+CALA=?

For example, 6th of July 2005, 22:10:00 equals to "05/07/06,22:10:00" (see also AT+CCLK). Note: If <time> equals current date and time or is set to an earlier date, TA returns +CME ERROR: 21. <n>(num) Integer type value indicating the array index of the alarm. The ME allows to set only one alarm at a time. Therefore, the list of supported alarm events indicated by the test command AT+CALA=? is <n>=0. If a second alarm time is set, the previous alarm will be deleted. Therefore, the read command AT+CALA? will always return <n>=0. This is also true if individual settings are made on ASC0 and ASC1 or the various Multiplexer channels, for details see notes below. <type>(num) Integer type value indicating the type of the alarm. 0 Alarm indication: text message via serial interface <text>(str) String type value indicating the text to be displayed when alarm time is reached; maximum length is <tlength>. By factory default, <text> is undefined. Note: <text> will be stored to the non-volatile flash memory when the device enters the Power Down mode via AT^SMSO. Once saved, it will be available upon next power-up, until you overwrite it by typing another text. This eliminates the need to enter the full string when setting a fresh alarm. <text> should not contain characters which are coded differently in ASCII and GSM (e.g. umlauts), see also "Supported character sets" and "GSM alphabet tables". <tlength>(num) Integer type value indicating the maximum length of <text>. The maximum length is 16. Notes • After the alarm was executed the parameter <time> of AT+CALA will be reset to "00/01/01,00:00:00", but <text> will be preserved as described above. • If MC55 is totally disconnected from power supply the most recently saved configuration of +CALA: <time>[,<n>[,<type>[,<text>]]] will be presented when MC55 is powered up. • Each time MC55 is restarted with ignition it takes 2s to re-initialize the RTC and to update the current time. Therefore, it is recommended to wait 2s before using the commands AT+CCLK and AT+CALA (for example 2s after ^SYSSTART has been output). MC55_ATC_V04.00 Confidential / Released Page 428 of 475 3/17/06 • Alarm settings on ASC0 / ASC1 and different Multiplexer channels (see AT+CMUX): - On each interface an individual <text> message can be stored, but only one time setting applies. This means an alarm <time> set on one of the interfaces overwrites the time setting on all remaining interfaces. Therefore, the total number of alarm events returned by the read command AT+CALA? will always be <n>=0, no matter whether different text messages are stored. - When the scheduled alarm occurs, the ME sends the URC only on the interface where the most recent alarm setting was made. The alarm time will be reset to "00/01/01,00:00:00" on all interfaces.

The automatic shutdown caused by undervoltage is equivalent to the powerdown initiated with the AT^SMSO command, i.e. ME logs off from the network and the software enters a secure state avoiding loss of data. When the module is in IDLE mode it takes typically one minute to deregister from the network and to switch off. For further details regarding automatic shutdown and voltage ratings please refer to the Hardware Interface Description [2]. The AT^SBC read command displays the average current consumption of the module and, if specified, of the external application. • Functions available with battery connected: The AT^SBC read command can be used to query the status of the battery and the charger. The AT^SBC write command is important for entering the current consumption of the external application via <current>. It should be noted that the charge control supported by MC55 works only if the requirements described in the Hardware Interface Description [2] are met (battery type Lithium-Ion or Lithium Polymer, presence of an NTC and protection circuit etc.) and if <current> is correctly specified. If the battery does not incorporate an NTC, or the battery and the NTC are not compliant with the specified requirements the battery cannot be detected by MC55. Syntax Test Command AT^SBC=?

When the external charging circuit includes an NTC connected to the BATT_TEMP pin, the URC appears several times before the module switches off. The undervoltage protection is also efficient in applications which are not battery operated, i.e. where no NTC is connected to the BATT_TEMP pin. To use this feature it is sufficient to issue the write command which automatically enables the presentation of URCs. You do not need to specify <current>. Please note, that in contrast to applications with an NTC, MC55 will present the undervoltage URC only once and will then switch off without sending any further messages. Parameter Description <bcs>(num) Connection status of battery pack 0 No charging adapter is connected 1 Charging adapter is connected 2 Charging adapter is connected, charging in progress 3 Charging adapter is connected, charging has finished 4 Charging error, charging is interrupted 5 False charging temperature, charging is interrupted while temperature is beyond allowed range <bcl>(num) Battery capacity 0, 20, 40, 60, 80, 100 percent of remaining capacity (6 steps). 0 indicates that either the battery is exhausted or the capacity value is not available. While charging is in progress (charging adapter connected) the battery capacity is not available. Consequently, parameter <bcl>=0. To query the battery capacity disconnect the charger. <mpc>(num) Average current consumption. Value (0...5000) of average current consumption (mean value over a couple of seconds) in mA. <mpc> is obtained from the MC55's current consumption, plus the value you have specified for the application by using the write command AT^SBC=<current>. Remember that the current consumption of MC55 varies with its operating mode (IDLE, TALK, DATA, GPRS/DATA) and the power level. If <current> was not yet specified and no battery pack NTC is detected <mpc> returns only the module's present current consumption. If <current> was not yet specified, but the NTC of the connected battery pack is detected, an offset value of 200mA will, by default, be added. 200mA is an estimated value which represents the current consumption of a typical external application. Drawn from practical experience it serves as a precaution to ensure proper charging in case you have not entered <current>. It is strongly recommended that you enter the correct power consumption of your application as described below. <current>(num) Enter the current consumption of your host application in mA (0...5000). If used, the current provided over the 2.9V VDD pin of the application interface (maximum 70mA) must be added, too. When the MC55 is powered down or reset, the value of <current> is restored to its default. This affects the charging control and disables the presentation of Unsolicited Result Codes. Therefore, the parameter should be set every time when needed after rebooting the MC55. MC55_ATC_V04.00 Confidential / Released Page 431 of 475 3/17/06 Notes • If multiplex mode (AT+CMUX) is active, any virtual channel can be used for entering the read or write command. The undervoltage URC will be issued simultaneously on all three channels. • The URC "^SYSSTART CHARGE ONLY MODE" is indicated automatically when the module enters this mode (except when autobauding is active). Unlike the undervoltage URC, it cannot be disabled or enabled by the TE. 18.3.1 Responses returned by read command Responses returned by the AT^SBC read command vary with the operating mode of the MC55: • • • • Normal mode: MC55 is switched on by Ignition pin and running in SLEEP, IDLE, TALK or DATA mode. Charger is not connected. The AT^SBC read command indicates the battery capacity and the current consumption of the MC55 module and the application (if value of application was specified before as <current>). Normal mode + charging: Allows charging while MC55 is switched on by Ignition pin and running in SLEEP, IDLE, TALK or DATA mode. The AT^SBC read command returns only charger status and current consumption of the MC55 module and the application. Percentage of battery capacity is not available. CHARGE ONLY mode: Allows charging while MC55 is detached from GSM network. When started, the mode is indicated by the URC "^SYSSTART CHARGE ONLY MODE". The AT^SBC read command returns only the charger status and current consumption of the MC55 module and the application. Percentage of battery capacity is not available. In CHARGE ONLY mode a limited number of AT commands is accessible (see Appendix). There are several ways to activate the CHARGE ONLY mode: - from POWER DOWN mode: Connect charger while the MC55 was powered down with AT^SMSO - from Normal mode: Connect charger, then enter AT^SMSO. Alarm mode: The battery can be charged while the MC55 stays in Alarm mode, but the AT^SBC read command returns only charger status and current consumption of the MC55 module and the application. Percentage of battery capacity is not available.

Parameter Description <n>(num) 0(&F)(P) Presentation of URCs is disabled (except for <m> equal to -2 or +2). 1 Presentation of URCs is enabled. <m>(num) -2 Below lowest temperature limit (causes immediate switch-off) -1 Below low temperature alert limit 0 Normal operating temperature 1 Above upper temperature alert limit 2 Above uppermost temperature limit (causes immediate switch-off) Notes • Please refer to the "Hardware Interface Description" for specifications on critical temperature ranges. • To avoid damage the module will shut down once the critical temperature is exceeded. The procedure is equivalent to the power-down initiated with AT^SMSO. • URCs indicating the alert level "1" or "-1" are intended to enable the user to take appropriate precautions, such as protect the module and the battery from exposure to extreme conditions, or save or back up data etc. The presentation of "1" or "-1" URCs depends on the settings selected with the write command: If <n>=0: Presentation is enabled for 15 s time after the module was switched on. After 15 s operation, the presentation will be disabled, i.e. no URCs will be generated. If <n>= 1: Presentation of "1" or "-1" URCs is always enabled. • Level "2" or "-2" URCs are followed by immediate shutdown. The presentation of these URCs is always enabled, i.e. they will be output even though the factory setting AT^SCTM=0 was never changed. • If the temperature limit is exceeded while an emergency call is in progress the engine continues to measure the temperature and to deliver alert messages, but deactivates the shutdown functionality. Once the call is terminated full temperature control will be resumed. If the temperature is still out of range ME switches off immediately. Examples EXAMPLE 1 URCs issued when the operating temperature is out of range: ^SCTM_A: ^SCTM_A: ^SCTM_B: ^SCTM_B: ^SCTM_A: ^SCTM_A: ^SCTM_B: ^SCTM_B: 1 2 1 2 -1 -2 -1 -2 MC55_ATC_V04.00 Confidential / Released Caution: Battery close to overtemperature limit.

Please note that the SYNC pin may be assigned different functions: Depending on the design of the host application, the pin can either be used to indicate the current consumption in a transmit burst or to drive a status LED connected to the pin as specified in [2]. For detailed information on the SYNC pin and its LED functionality refer to [2]. Before changing the mode of the SYNC pin, carefully read the technical specifications. Syntax Test Command AT^SSYNC=? Response(s) ^SSYNC:list of supported <mode>s OK Read Command AT^SSYNC? Response(s) ^SSYNC:<mode> OK Write Command AT^SSYNC=<mode> Response(s) OK Reference(s) PIN SIEMENS ! ASC0 ASC1 % % MUX1 MUX2 % % MUX3 Charge % ! ! Last ! Parameter Description <mode>(num) Operation mode of the SYNC pin. Setting is stored non-volatile. 0(D) SYNC mode: Enables the SYNC pin to indicate growing power consumption during a transmit burst. You can make use of the signal generated by the SYNC pin, if power consumption is your concern. To do so, ensure that your application is capable of processing the signal. Your platform design must be such that the incoming signal causes other components to draw less current. In short, this allows your application to accommodate current drain and thus, supply sufficient current to the GSM engine if required. 1 LED mode: Enables the SYNC pin to drive a status LED installed in your application according to the specifications provided in [2]. The coding of the LED is described in Section 18.6.1, ME status indicated by status LED patterns. MC55_ATC_V04.00 Confidential / Released Page 437 of 475 3/17/06 18.6.1 ME status indicated by status LED patterns The following table lists the possible patterns of status LED behavior, and describes the ME operating status indicated by each pattern if AT^SSYNC parameter <mode>=1. During the transition from one LED pattern to another the "on" and/or "off" periods of the LED may vary in length. This is because an event that triggers the change may occur any time and, thus, truncate the current LED pattern at any point. Table 18.1: Modes of the LED and indicated ME functions LED behavior ME operating status if AT^SSYNC=1 Permanently off ME is in one of the following modes: - POWER DOWN mode - ALARM mode - CHARGE ONLY mode - NON-CYCLIC SLEEP mode - CYCLIC SLEEP mode with no temporary wake-up event in progress 1) 600 ms on / 600ms off Limited Network Service: No SIM card inserted or no PIN entered, or network search in progress, or ongoing user authentication, or network login in progress. 75 ms on / 3 s off IDLE mode: The mobile is registered to the GSM network (monitoring control channels and user interactions). No call is in progress. 75 ms on / 75 ms off / 75 ms on / 3 s off One or more GPRS PDP contexts activated. 500 ms on / 25 ms off Packet switched data transfer is in progress. Permanently on Depending on type of call: Voice call: Connected to remote party. Data call: Connected to remote party or exchange of parameters while setting up or disconnecting a call. 1) When a temporary wake-up event (for example a call, a URC, a packet switched transfer) occurs in CYCLIC SLEEP mode the LED flashes according to the patterns listed above. See Section 2.8.1, Wake up the ME from SLEEP mode for details on the various SLEEP modes and wake-up events. MC55_ATC_V04.00 Confidential / Released Page 438 of 475 3/17/06 19.
