Document conventions
Throughout the document, the GSM engines are referred to as ME (Mobile Equipment), MS (Mobile Station), TA
(Terminal Adapter), DCE (Data Communication Equipment) or facsimile DCE (FAX modem, FAX board). When
the Siemens product names are required to distinguish the two models, MC35i is short for the engine type and
MC35iT for the terminal.
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 19.3, Available AT Commands and Dependency on SIM
PIN uses the same symbols.
ASC0:
Is the AT command supported on the physical serial interface ASC0?
%
Yes
!
No
Note: In the case of MC35i only "Yes" applies.
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 physical serial interface is partitioned into 3 virtual channels by
using the Multiplexer protocol. Usage is the same on ASC0 and MUX1.
Example:

AT Command Syntax
The "AT" or "at" prefix must be set at the beginning of each command line. 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.
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 within 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.25ter command is omitted, its value is assumed to be 0.

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 command line buffer accepts a maximum of 391 characters. If this number is exceeded none of the commands will be executed and TA returns ERROR.
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.

concern, avoid concatenating commands on the same line.

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.

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.

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.

The relation of SIM bytes to output bytes is given in parentheses.
Case 1
Every GSM character is sent to 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 will is sent to 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 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 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 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 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"

Case 6

The relation between number of input characters and stored bytes on SIM is given in parentheses.
Case 1
Every character is sent from TE to TA as GSM character (or ASCII with 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 to TA 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 to TA as 4 IRA characters.
Maximum text length is 280 IRA characters which will be converted into 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 to TA 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

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.

1.6 Serial Interface Flow Control
1.6
mobile
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.

1.7 Unsolicited Result Code Presentation
1.7
mobile
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 19.6, Summary of Unsolicited Result Codes (URC).
To announce a pending URC transmission the ME will do the following:
•
Activates its Ring line (logic "1") for one second, i.e. the line changes to physical "Low" level. This allows the
TE to enter power saving mode until ME related events request service.
•
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
-
while an AT command is being processed, i.e. during the time from sending the first character "A" of an
AT command by the TE until the ME has responded with "OK" or "ERROR", or
-
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 MC35i, for details refer to [6] 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 an 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 19.6, Summary of Unsolicited Result Codes (URC).
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 MC35i
Leaving hardware flow control unconsidered the Customer Application (TE) is coupled with the MC35i (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 MC35i starts sending an URC. This probably will 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 MC35i 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 MC35i using activated echo (ATE1), i.e. the MC35i 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 over both the receive and the transmit paths. This way no URC can be issued by the MC35i in
between.

Errors and Messages
The final result codes "+CME ERROR: <err>" and "+CMS ERROR: <err>" indicate errors related to mobile equipment or network. The effect is similar to an ERROR result code.
A final 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 code are returned
for these commands. A 30 seconds timeout causes ERROR to be returned when the input of a command is not
complete.
The format of <err> can be either numeric or verbose. The setting is made with the command AT+CMEE.

2.8 AT+CFUN
2.8
mobile
AT+CFUN Set phone functionality
This 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 or 8.
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>= 5, 6, 7 or 8,
since in these modes MC35i 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
MC35i 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 or 8) 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.

The test command returns the values of the supported parameters.
The read command returns the current functionality value.
The write command can be used to reset the ME, to choose one of the SLEEP modes or to return to full functionality.
Parameter Description
<fun>(num)
0
NON-CYCLIC SLEEP mode:
In this mode, the AT interface is not accessible. Consequently, once you have
set <fun> level 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)
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 during paging. 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 during paging.
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.

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
•
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 [6],
Section "Power saving control".
•
When a circuit-switched call is in progress, <fun>=7 or 8 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 MC35i 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 or 8.
AT+CFUN?
+CFUN: 5
CYCLIC SLEEP mode
EXAMPLE 2
To set the ME to NON-CYCLIC SLEEP mode enter
AT+CFUN=0
OK
When, for example, an SMS is being received and indicated by an unsolicited result code (URC), the ME
wakes up to full operation.
+CMTI: "SM",5
Note that the URC used in this example will appear only, if AT+CNMI=1,1 was configured before.
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:
AT+CFUN=1,1
or alternatively, AT+CFUN=0,1 or 5,1 or 6,1 or 7,1 or 8,1
OK
^SYSSTART
MC35i_ATC_V01.03
Confidential / Released
The ^SYSSTART URC confirms that the ME has been rebooted. Note
that ^SYSSTART appears only if AT+IPR ¹ 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 current. Depending on the selected mode, the wakeup 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, Wake-up events in NON-CYCLIC and CYCLIC SLEEP
modes:
•
Quit: ME exits SLEEP mode.
•
Temporary: ME becomes active temporarily for the duration of the event and the mode-specific follow-up time
after the last character was sent or received on the serial interface.
•
No effect: Event is not relevant in the selected SLEEP mode. The ME does not wake up.

If AT^SMSO is entered on one of the Multiplexer channels the ME closes the Multiplexer channels, terminates
the Multiplexer and deactivates all other functions. Then, the URC "^SHUTDOWN" will be issued on the physical serial interface (ASC0). The URC will be transmitted at the bit rate last activated on ASC0 for use with
the Multiplex driver.

•
If the ME operates on different instances (MUX channels 1, 2, 3) 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

AT+CIND Indicator control
This command controls information about status changes via URC presentation of the MC35i or connected
items, e.g. 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 this command is outdated since additional indications and functionality are available with AT^SIND.
AT+CIND supports two ways to get the values related to indicators:
•
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=[<state>[,<state>[,...]]].
•
Evaluate one of the "+CIEV" URCs which the ME automatically sends to the application, whenever the value
of the associated indicator changes.
The presentation of these URCs depends on two settings:
-
The indicators must be registered with the write command AT+CIND=[<state>[,<state>[,...]]]. By
default, all of them are registered when the ME is switched on. Any URC can be excluded if deregistered
with <state>=0.
-
URC presentation must be enabled with AT+CMER.

Command Description
The read command returns the status of the ME indicators.
The write command is used to switch the event report for each indicator type. The Indicator Event Reports are
displayed to the TE via "+CIEV" which can be enabled using AT+CMER.
Parameter Description
<indValue>(num)
Integer type value, which shall be in range of corresponding <indDescr>
<indDescr>(str)
String values and their <indValue> ranges.
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 always equals 5, i.e. value is not relevant for MC35i
“signal“
Signalquality (0..7) or (99) if not measurable. The indicated value is the bit error
rate of the signal received. If there are bit errors this is not a constant but a estimated value which will change in time. 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). The indicator provides information about tones generated in the ME. Value 1 means for example:
Incoming call - ME is ringing. Note that the URC "+CIEV: sounder" indicator 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 if 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".
“roam“
Roaming indicator (0-1)
0: Registered to home network or not registered
1: Registered to other network

[1](P)
Indicator is registered, indicator event report allowed.
Notes
•
Due to its restrictive range of values, there are events when it is not entirely clear from the context, which
event has led to the output of indicator "call". Rather than as an information in itself, indicator "call" should
therefore be used as a trigger to look up the new call status in the list of current calls with AT commands
AT+CLCC or AT^SCNI.
•
The indicator "sounder" signals every event a tone is generated in the ME. For instance, if a waiting call produces a tone, this will be indicated.
•
If the ME is switched on all indicators are in registered state.
•
Use AT+CMER command to allow Indicator Event Report of all registered indicators.
Example
^SYSSTART
AT+CPIN=9999

AT+CIND?
+CIND: 5,99,1,0,0,0,0,0
The battery is either full or no battery is connected to the ME. The bit
error rate of the signal quality is not available (since there is no call in
progress). The ME is registered to its home network.
OK

AT^SIND Extended Indicator Control
AT^SIND supplies extended event indicator control and
•
offers greater flexibility than standard AT+CIND,
•
offers several extra indicators,
•
can show the current status of all indicators supported by AT+CIND and AT^SIND,
•
gives the possibility to register or deregister the indicators of both commands,
•
displays all indicator event reports via "+CIEV" URCs.
Presentation mode of the generated URCs is controlled via AT+CMER.
AT^SIND read command provides a list of all indicators supported by AT+CIND and AT^SIND. Each indicator is
represented with its registration mode and current value.
The write command can be used to select a single indicator in order to modify its registration and to view the
current value.

<indDescr>(str)
String values and their <indValue> ranges.
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:
“netlost“
0 .. Network registration or location update succeeded.
1 .. Network registration or location update failed because of bad uplink connection.
“ciphcall“
Ciphering Status Change Indication
As stated in GSM specifications 02.07 and 02.09 the ciphering indicator feature
allows the MC35i 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.
Note:
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.
•
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.
0 .. Current call or SMS is not ciphered.
1 .. Current call or SMS is ciphered.

The release cause report is presented in numeric format. Default output in case of a none-error-situation is
+CEER: 0,0,0. A description associated with each number can be found in the tables given in the following subclauses and the relevant GSM specifications.
The first parameter <locationID> serves to locate the other two parameters. Depending on the failure or
release cause either <reason> or <ssRelease> are applicable, i.e. if <reason> ¹ 0, then <ssRelease> = 0.
Vice versa, if <reason> = 0, then <ssRelease> may be ¹ 0.

Notes
•
When using XON/XOFF flow control (AT\Q1) in online mode, +++ should not be used while the data transmission is paused with XOFF. Before entering the command mode with +++ the paused transmission should
be resumed using the XON character.
•
For compatibility reasons, the AT\Q command can be used in Multiplex mode, though the settings will not
take effect. However, be aware that whenever you use the AT\Q write command in Multiplex mode and then
save the current configuration to the user profile with AT&W, the changed AT\Q setting will become active after
restart.

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 DTE (TE) and DCE (TA) are configured to the same rate. When you select autobauding, the DCE will automatically recognize the bit rate currently used by the DTE.
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 DCE bit rate will not be saved and, therefore, needs
to be resynchronized after restarting the GSM engine (see Section 4.7.1, Autobauding).

Notes
•
Factory default is autobauding enabled (AT+IPR=0). 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 delay of 100ms is required between the response to the last command (e.g. OK)
and the next command on the same line.
-
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 is operated in Multiplex mode we suggest a minimum bit rate of 4800bps.
•
A selected bit rate takes effect after the write commands returns OK (except for Multiplex mode).
•
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.

Autobauding
To take advantage of autobaud mode specific attention must be paid to the following requirements:
•
Synchronization between DTE and DCE
Ensure that DTE and DCE are correctly synchronized and the bit rate used by the DTE is detected by the
DCE (ME). 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 DTE-DCE synchronization, when you activate autobauding first and then configure the autoanswer mode (ATS0 ¹ 0).
•
•
Restrictions on autobauding operation
-
The serial interface shall be used with 8 data bits, no parity and 1 stop bit (factorysetting), 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.
-
It is not recommended to switch to autobauding from a bit rate that cannot be detected by the the autobaud
mechanism (e.g. 300 bps). Responses to AT+IPR=0 and any commands on the same line might be corrupted.
-
MC35i Terminal version: autobauding should not be used at bitrates over 115200bps.
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 cannot be accepted. This must be taken into account when autobauding and
autoanswer mode (ATS0 ¹ 0) are enabled at the same time, escpecially if SIM PIN 1 authentication is done
automatically and the setting ATS0 ¹ 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" 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 DCE to DTE 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).

GSM 07.07, GSM 07.10
Command Description
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 MC35i 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 [6] 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

•
The write command is used to enter the multiplex mode. 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 GSM07.10 is fixed to 97 and cannot be changed.
All other parameters are not available.

Restrictions on Multiplex mode
In multiplex mode, CSD 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 [6].

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 [6], 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.
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.

Notes
•
Caution: After entering a password with AT+CPIN all other commands that need access to data on the SIM
card may be blocked for up to 20 seconds!
•
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
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.
ME 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).
•
Wait 10 seconds after PIN input before using SMS related commands.
•
<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.
Number of failed attempts
Time to wait before next input is allowed
1st failed attempt
No time to wait
2nd failed attempt

3 * 256 seconds
4th failed attempt
4 * 256 seconds
5th failed attempt
5 * 256 seconds
6th failed attempt and so forth
6 * 256 seconds and so forth
SIM locks:
These are factory set locks, such as "PF", "PN", "PU", "PP", "PC". 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.
Summary of related sections:
Related +CME errors are listed in Section 2.11.1, CME ERRORS related to GSM 07.07. For further instructions

Use the read commands "AT+CPIN?" and "AT+CPIN2?" to check which password is currently required.
If the responses to "AT+CPIN?" and "AT+CPIN2?" both read "READY", there is no currently required password, and the referrer of the execute command "AT^SPIC" is explicitly undefined.
In these cases, the read command "AT^SPIC?" may be used to determine, which password the response of

For passwords associated to the phone lock (''PS'' lock set by client or factory) or other factory set locks, such
as ''PF'', ''PN'', ''PU'', ''PP'', ''PC'' the number of attempts is subject to a timing algorithm explained in
AT+CPIN. If these passwords are incorrectly entered the counter first returns 3, 2 and 1 remaining attempt(s),
but then gives the total number of attempts which amounts to 63 (see example below).

Parameter Description
<facility>(str)
Phone security locks set by client or factory
Primarily intended for the client to take safety precautions, "SC", "PS" and "FD" can be configured individually.
"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.
<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:

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 com-

patibility 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.

Supplementary Service Call Barring:
Supplementary Service "Call Barring" allows to specify conditions under which calls will be disallowed by the
network.
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.

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".

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

Parameter Description
<facility>(str)
Phone security locks set by client or factory:
Primarily intended for the client to take safety precautions, passwords "SC" (SIM PIN) and "P2" (SIM PIN2) are
usually predefined, but can be configured individually. The password for lock facility "PS" may also be factory
set.
“SC“
SIM PIN. SIM requests password upon ME power-up and when this lock command is issued.
If incorrectly entered three times, the SIM PUK is required to perform authentication. Input of the SIM PUK password is possible only with AT command
AT+CPIN or ATD. For further details please refer to Section 5.1.1, What to do
if PIN or password authentication fails?.
<password length>: 4 to 8 digits.
“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. 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. Input of the SIM PUK 2 password is possible only with AT command
AT+CPIN2 or ATD. For further detail please refer to Section 5.1.1, What to do
if PIN or password authentication fails?.
<password length>: 4 to 8 digits.
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.

Supplementary Service Call Barring:
Supplementary Service "Call Barring" allows to specify conditions under which calls will be disallowed by the
network.
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.
<password length>: The Network Password needs to be supplied from the network provider or network operator. Usually there is one 4 digit password which applies to all call barring options. For details contact your provider.

<password length>(num)

length of password. The range of permitted length for a password depends on
the associated <facility>. It is available from the test command response,
or in the description of parameter <facility>.
<old password>(str)
Password specified for the facility.
Parameter <old password> can be ignored if no old password was allocated to the facility.
Take into account that a password may have already been set by factory, or that the service is subject to a password issued by the provider. See notes above or contact provider.
<new password>(str)
New password. Mandatory, if <old password> was an unblocking key (such as the Master Phone Code).
Note
•
To delete a password use the following syntax:

change the "PS" password): use the master phone code.
CAUTION: THIS TEST SHOULD BE PERFORMED ONLY IF THE CORRECT MASTER PHONE CODE FOR
THE INDIVIDUAL ME USED IS DEFINITELY AVAILABLE! Otherwise the module used will be rendered useless until the correct master phone code is entered!:
where 12345678 is the Master Phone Code and
1111 is the new password. You may also use <new

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.25ter modifiers: 0-9, *, #, +, A, B, C
The following V.25ter modifiers are ignored: ,(comma), T, P, !, W ,@
Emergency call: <n> = 112 world wide number (no SIM needed)
Call to defined phone number to defer emergency switch-off when a critical temperature limit is exceeded: dialed
number must match the number defined in parameter <phone number> of write command AT^SCTM
<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.
Notes
•
The command may be aborted generally when receiving an ATH command during execution. It cannot be
aborted in some connection setup states, such as handshaking.
•
Parameter "I" and "i" only if no *#-code is within the dial string.
•
<mgsm> is not supported for data calls.
•
<n> is default for last number that can be dialled by ATDL.
•
See also ATX for <text>.
•
If ATD is used with a USSD command (e.g. ATD*100#;) an AT+CUSD=1 is executed implicitly (see AT+CUSD).
•
Parameter 'G' or 'g' will be ignored if Closed User Group was already activated, respectively deactivated with
AT+CCUG command before. 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. In addition, the blacklist can be deleted using the AT^SPBD command.

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
Dialing out the first party's number.
OK
The first call is established.
ATD03022222222
The number of the second party is dialed.
OK
The response "OK" is issued immediately though no call is established
(same behavior as is you had chosen AT^SM20=0.)
BUSY
Line of the second called party is busy.

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.

AT+COPS Operator selection
This command can be used to query the present status of the ME's network registration and to determine
whether automatic or manual network selection shall be used.
Automatic mode: Lets the ME automatically search for the home operator. If successful the ME registers to the
home network and enters the IDLE mode. If the home network is not found, ME goes on searching. If then a
permitted operator is found, ME registers to this operator. If no operator is found the ME remains unregistered.
Manual mode: Desired operator can be manually entered, using the AT+COPS write command syntax. If operator is found, ME registers to this operator immediately. If the selected operator is forbidden, the ME remains
unregistered.
Manual/automatic: In this mode, the ME first tries to find the operator that was manually entered. If the ME fails
to register to this operator, then it starts to select automatically another network.

Command Description
The test command returns a list of quadruplets, each representing an operator present in the network. Any of the
formats 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 read command returns the current <mode> and the currently selected operator. If no operator is selected,
<format> and <oper> are omitted.
The write command forces an attempt to select and register the GSM network operator. 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 (+COPS?), too.

Service states
Depending on the service state, an additional textual output is generated (refer also to the response examples):
•
'Searching' - The MS is searching, but could not (yet) find a suitable cell. This output appears after restart of
the MS or after loss of coverage.
•
'No connection' - The MS is camping on a cell and registered to the network. The service state is 'idle', i.e.
there is no connection established or a dedicated channel in use.
•
'Cell Reselection' - The MS has not yet lost coverage but is searching for a better cell, since the cell reselection criterion is fulfilled.
•
'Limited Service' - The MS is camping on a cell but not registered to the network. Only emergency calls are
allowed. The MS enters this state, for example, when
-
no SIM card is inserted, or PIN has not been given,
-
neither Home PLMN nor any other allowed PLMN are found,
-
registration request was not answered or denied by the network (use command AT+CREG to query the
registration status),
-
authentication failed.
8.6.3
Notes
•
The parameters LAC and cell are presented as hexadecimal digits, the remaining parameters are composed
of decimal digits.
•
If the radio cell changes during a connection, the parameters PWR, RXLev and C1 of the 'Serving Cell' part
cannot be updated under certain conditions and therefore, are displayed as "-" (for conditions see also

AT+CREG). This is because the MS does not update the cell selection and reselection parameters since, in
this mode, they are not relevant for operation. When the connection ends, and the mobile is back to IDLE
mode, correct values will be given.
If the radio cell changes during a connection, it normally takes 1 or 2 seconds to update the parameters cell,
NCC and BCC. Until the information is received from the new base station, the default values will be shown
instead: cell="0000", NCC="-", BCC="-".
•
If the BS supports frequency hopping during a connection, the dedicated channel (parameter chann) is not
stable. This mode is indicated by chann = 'h'.
•
To some extent, the cell monitoring command AT^SMONC covers the same parameters. The receiving level,
for example, can be queried with both commands. Yet the resulting values may be slightly different, even
though obtained over a time period of a few seconds. This is quite normal and nothing to worry about, as the
cell information is permanently updated.
•
for compatibility with earlier products and to support legacy applications, any input character may be used to
stop the output in certain cases (depending on the settings of Section 4.7, AT+IPR and Section 4.8,
AT+CMUX).

Note
•
Due to the fact that not all necessary information of the neighbour cells can be decoded during a connection,
there are several constraints to be considered:
-
Only neighbour cells that have already been visible in IDLE mode will be further updated, as long as they
are still included in the list.
-
Though new neighbour cells can be added to the list (e.g. due to handover), their C1 and C2 parameters
cannot be displayed until the connection is released. In this case "-" is presented for C1 and C2.
-
To some extent, the cell monitoring command AT^SMONC covers the same parameters. The receiving
level, for example, can be queried with both commands. Yet the resulting values may be slightly different,
even though obtained over a time period of a few seconds. This is quite normal and nothing to worry about,

•
You can register, disable, enable and erase <reason> 4 and 5 as described above. However, querying the
status of <reason> 4 and 5 with AT+CCFC will result in an error ("CME error: Operation not supported"). As
an alternative, you may use the ATD command followed by *'# codes to check the status of these two reasons.
See List of Star-Hash (*#) Codes for a complete list of *# GSM codes. See also examples below.
•
Most networks will not permit registration of new parameters for conditional call forwarding (reasons 1,2,3,5)
while unconditional call forwarding is enabled.
•
The AT+CCFC command offers a broad range of call forwarding options according to the GSM specifications.
However, when you attempt to set a call forwarding 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 call forwarding status with <mode>=2.
•
Some networks may choose to have certain call forwarding condtions permanently enabled (e.g. forwarding
to a mailbox if the mobile is not reachable). In this case, erasure or deactivation of call forwarding for these
conditions will not be successful, even if the CCFC request is answered with response "OK".
•
The command has been implemented with the full set of <class> parameters according to GSM 07.07. For
actual applicability of SS "call forwarding" to a specific service or service group (a specific <class> value)
please consult table A.1 of GSM 02.04.
•
there is currently no release of GSM standard "GSM 02.04", in which the "Call Forwarding" Supplementary
Service is defined as applicable to SMS services
Example
Please note that when you configure or query call forwarding without specifying any classes, the settings will
refer to classes 1, 2 and 4 only (=default). The handling of classes is equivalent to AT+CLCK.
•
To register the destination number for unconditional call forwarding (CFU):

Notes
•
If the active call is a CSD call, and a waiting call is received, then the ME produces a BREAK while still in
online mode, and displays
-
the +CCWA URC (as above) when the ME goes back to command mode while the waiting call is still active
and can be accepted;
-
or the ^SCWA URC (as above) when the ME goes back to command mode after the waiting call has
ended.
•
With the AT+CHLD command, it is possible to establish a multiparty call or to set the active voice call on hold
and then accept a waiting voice call (not possible with fax and data call). 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 MC35i can only request the service, but the network
decides whether and how the request will be answered.

Release all held calls or set User Determined User Busy (UDUB) for a waiting

•
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.

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.
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.).
•
This Supplementary Service is only applicable to Teleservice 11 (Speech telephony), that is, voice calls can
be put on hold, while data or fax calls cannot. For example, with AT+CHLD=2 you can simultaneously place a
voice call on hold and accept another waiting voice call. But it is possible to place a voice call on hold in order
to accept a waiting data of fax call, and afterwards recover the voice call. In this case, the only difference over
speech telephony is that the data or fax call needs to be manually accepted via ATA (see example below).
•
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.

+CLIP: <number>, <type>
When CLIP is enabled at the TE (and is permitted by the calling subscriber), an unsolicited result code is
returned after every RING (or +CRING: <type>) at a mobile terminating call.
Command Description
Test command returns values supported by the TA as a compound value.
Read command gives the status of <n>, and also triggers an interrogation of the provision status of the CLIP
service according GSM 02.81 (given in <m>).
If no SIM card is available or SIM-Pin isn't entered, the command response is "ERROR".

<ppu>(str)
Price per unit; dot is used as a decimal separator (e.g. "2.66"). The length is limited to 20 characters. If the string
length is exceeded, the command is terminated with an error. This string may only contain digits and a dot. Leading zeros are removed from the string. The minimum and maximum value are determined by the structure of the
SIM-PUCT file. The maximum price per unit value is 999 999 999.00. When successfully entered, this value is
rounded to maximum accuracy.
Note: Due to storage in mantisse (range 0-4095) and exponent (-7 to 7) it is possible that rounding errors occur.
<passwd>(str)
SIM PIN2. String parameter which can contain any combination of characters. The maximum string length is
limited to 8 characters. If this value is exceeded, the command terminates with an error message. If the PIN2 is
incorrect, a CME error (+CME ERROR: incorrect password) is output.
Example
To change currency and/or price per unit you have two ways:
You can enter PIN2 along with the AT+CPUC command:
AT+CPUC="EUR","0.10","8888"
(where "8888" = PIN2)
OK
Alternatively, you can first use the AT+CPIN2 command to enter PIN2. When you execute the AT+CPUC command, subsequently, take into account that PIN2 authentication expires after 300ms (see notes in AT+CPIN2).
AT+CPUC="EUR","0.10"

The write command is used to activate or deactivate the specified PDP context(s). After the command has completed, the MT remains in V.25ter 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 them 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, command returns with "ERROR" or with
"+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 with "ERROR" or with "+CME ERROR: unspecified GPRS error. In this case AT+CEER returns
"+CEER: 51,3,0".
Parameter Description
<state>(num)
Indicates the state of PDP context activation.
0

[1]
attached
<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, write command returns with "+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 indiacte 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.

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.25ter
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.

Notes
•
If the MT is in dedicated mode, write command returns with "+CME ERROR: operation temporary not
allowed".
•
It is possible to leave the GPRS data mode and enter the command mode by using the V.25ter 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.25ter command ATO, which is usable for GPRS connections too. In this case the first context is used, which is active and which was already in data mode since
it was activated (the internal context, which is used for GPRS connection without explicitely specifiying a context identifier, has the highest priority).
It ist possible, to use AT+CGDATA to enter the data mode for a context, which was not in data mode since it
was activated. With ATO this is not possible.

Command Description
The test command returns values supported as a compound value. If the MT supports several PDP types, the
parameter value ranges for each PDP type are returned on a separate line.
The read command returns the current settings for each defined context. If no minimum profile was explicitly
specified for a context, simply OK will be returned, but default values will be used for that context.
This command allows the TE to specify a minimum acceptable profile which is checked by the MT against the
negotiated profile returned in the Activate PDP Context Accept message.
The set command specifies a profile for the context identified by the (local) context identification parameter,

<cid>.
A special form of the set command, AT+CGQMIN= <cid> causes the minimum acceptable profile for context
number <cid> to become undefined. In this case no check is made against the negotiated profile.
AT&F and ATZ will undefine the minimum QoS profiles of every context which is not active or not online.

Command Description
This command causes the MT to perform whatever actions are necessary to establish communication between
the TE and the external PDN.
The V.25ter 'D' (Dial) command causes the MT to enter the V.25ter online data state and, with the TE, to start
the specified layer 2 protocol. No further commands may follow on the AT command line. GPRS attachment and
PDP context activation procedures may take place prior to or during the PDP startup if they have not already
been performed using the AT+CGATT and AT+CGACT commands. If the context to be used is already activated,
it will be deactivated first. This ensures that the right context parameters will be used (e.g. QoS changes since
the last context activation or the called address specified by ATD*99#).
Examples on how to use this command are provided in chapter "Using GPRS AT commands (Examples)".
To confirm acceptance of the command before entering the V.25ter online data state command will respond with
CONNECT.
When the layer 2 protocol has terminated, either as a result of an orderly shut down of the PDP or an error, the
MT enters V.25ter command state and returns NO CARRIER.
Parameter Description
<called_address>(str)
IP V4 address in the form w.x.y.z, which identifies the called party; if it is provided, the MT will automatically set
up a virtual call to the specified address after the context has been activated. This parameter is currently not
used and needs not to be specified.
<L2P>(str)
Layer 2 protocol to be used between the TE and MT.

the layer 2 protocol.
GPRS attachment and PDP context activation procedures may take place prior to or during the PDP startup if
they have not already been performed using the AT+CGATT and AT+CGACT commands. If the context to be used
is already activated, it will be deactivated first. This ensures that the right context parameters will be used (e.g.
QoS changes since the last context activation).
To confirm acceptance of the command before entering the V.25ter online data state command will respond with
CONNECT.
When the layer 2 protocol has terminated, either as a result of an orderly shut down of the PDP or an error, the
MT enters V.25ter command state and returns NO CARRIER.
Parameter Description
<cid>(num)
Parameter specifies a particular PDP context definition (see AT+CGDCONT command). If no context is specified,
an internal context 0 with default properties is used (see AT+CGDCONT, AT+CGQREQ and AT+CGQMIN).

In contrast to GSM 07.07 it is possible to cancel a connection with ATH after a break. This is done for compatibility reasons due to the "dial-up network" drivers of Microsoft Windows.

Using GPRS AT commands (Examples)
Examples
EXAMPLE 1
Defining and using a Context Definition ID (CID):
Every time a CID is used as a parameter for a GPRS command the CID has to be defined before by using
the AT+CGDCONT command. To get the parameter of a CID use the AT+CGDCONT read option. If the response
of 'AT+CGDCONT?' is OK only, there is no CID defined.
AT+CGDCONT?
There is no CID defined
OK
All parameters of the CID are initiated by NULL or not present values, and the CID itself is set to be undefined.
To define a CID use the AT+CGDCONT command with at least one CID parameter. At the moment the mobile
supports CID 1 and CID 2 by using the AT+CGDCONT command.
Define CID 1 and set the PDP type to IP, access point name and IP address are not set:
AT+CGDCONT=1,"IP"
OK
Define CID 2 and sets PDP type, APN and IP addr:
AT+CGDCONT=2,"IP", "internet.t-d1.gprs", 111.222.123.234
OK
A following read command will respond:
AT+CGDCONT?
+CGDCONT:1,"IP","","",0,0
+CGDCONT:2,"IP","internet.t-d1.gprs",111.222.123.234
OK
Set the CID 1 to be undefined:
AT+CGDCONT=1
OK
A following read command will respond:
AT+CGDCONT?
+CGDCONT:2,"IP","internet.t-d1.gprs",111.222.123.234
OK
EXAMPLE 2
Quality of Service (QoS) is a special parameter of a CID which consists of several parameters itself.
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".

10.16 Using GPRS AT commands (Examples)
mobile
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. Now
set the QoS of CID 1 to not present:
AT+CGQREQ=1
OK
Once defined, the CID it can be activated. To activate CID 2 use:
AT+CGACT=1,2
OK
If the CID is already active, the mobile responds OK at once.
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
The mobile is connected using the parameters of
CID 1.
AT+CGDATA=
CONNECT
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. D2 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). As an alternative,
you can define and activate the context in a terminal program (e.g. Microsoft Hyperterminal) and then use the
Dial-Up Network to send only the ATD command.

RP layer SMSC address octets are not counted in the length) In text mode, the maximum length of an SMS
depends on the used coding scheme: It is 160 characters if the 7 bit GSM coding scheme is used, and 140 characters according to the 8 bit GSM coding scheme.
If the SMS message format is ''text mode'' (AT+CMGF=1) and the character set is set to ''UCS2'' with AT+CSCS
and the SMS is also coded as "UCS2" (see <dcs> of AT+CSMP), then the length is in octets instead of characters.

Notes
•
If there is no SMS stored at the selected index, the response is OK too.
•
This command should be used only after the SMS data from the SIM have been read successfully for the first
time. This may take up to 30 seconds after ^SYSSTART depending on the SIM used. A SMS delete attempt
before the SIM is ready will result in ''+CME Error: 14'' (SIM busy).
•
We recommend to take advantage of the "^SSIM READY" URC. If enabled with AT^SSET, this URC acknowledges to the user that SIM data is accessible after SIM PIN authentication. It will be delivered once the ME
has completed reading data from the SIM card.

Command Description
The execute command is the same as the write command with the given default for <stat>.
The write command returns messages with status value <stat> from message storage <mem1> to the TE. If
status of the message is 'received unread', status in the storage changes to 'received read'.
Notes
•
The selected <mem1> can contain different types of SMs (e.g. SMS-DELIVERs, SMS-SUBMITs, SMS-STATUS-REPORTs and SMS-COMMANDs), the response may be a mix of the responses of different SM types.
TE application can recognize the response format by examining the third response parameter.
•
The parameters <ra> and <tora> will only be displayed if parameter <ra> of the AT^SSCONF command is
set to 1.
•
This command can be used only after the SMS data from the SIM have been read successfully for the first
time. Reading starts after successful SIM authentication has been performed, and may take up to 30 seconds
depending on the SIM used. While the read process is in progress, an attempt to use any of the SMS read
commands will result in ''+CME Error: 14'' (SIM busy)
•
We recommend to take advantage of the "^SSIM READY" URC. If enabled with AT^SSET, this URC acknowledges to the user that SIM data is accessible after SIM PIN authentication. It will be delivered once the ME

Command Description
The write command returns SMS message with location value <index> from message storage <mem1> to the
TE. If status of the message is 'received unread', status in the storage changes to 'received read'.
Notes
•
Response if AT+CMGR is used to read an empty record index: +CMGR: 0,,0
•
Response if AT+CMGR is used to read a non-existent record index: +CMS ERROR: invalid memory index
•
The parameters <ra> and <tora> will only be displayed if parameter <ra> of the AT^SSCONF command is
set to 1.
•
This command can be used only after the SMS data from the SIM have been read successfully for the first
time. Reading starts after successful SIM authentication has been performed, and may take up to 30 seconds
depending on the SIM used. While the read process is in progress, an attempt to use any of the SMS read
commands will result in ''+CME Error: 14'' (SIM busy)
•
We recommend to take advantage of the "^SSIM READY" URC. If enabled with AT^SSET, this URC acknowledges to the user that SIM data is accessible after SIM PIN authentication. It will be delivered once the ME
has completed reading data from the SIM card.

Command Description
The write command transmits a short message from TE to network (SMS-SUBMIT).
After invoking the write command wait for the prompt ">" and then start to write the message. To send the message simply enter <CTRL-Z>. After the prompt a timer will be started to observe the input.
To abort sending use <ESC>. Abortion is acknowledged with "OK", though the message will not be sent.
The message reference <mr> is returned to the TE on successful message delivery. The value can be used to
identify the message in a delivery status report provided as an unsolicited result code.
Notes
•
If sending fails, for example, if a message is too long, the result code depends on the current setting of the
AT^SM20 command:

If the AT^SM20 <CmgwMode> equals 1 (factory default) any failure to send a message is responded with "OK".
Users should be aware, that despite the "OK" response, the message will not be sent to the subscriber.
If the AT^SM20 <CmgwMode> equals 0 any failure to send a message is responded with "ERROR".
•
If sending fails due to timeout, then
AT^SM20 <CmgwMode>=1 causes "+CMS ERROR: Unknown error" to be returned;
AT^SM20 <CmgwMode>=0 causes "+CMS ERROR: timer expired" to be returned.
•
Note that some providers do not recognize an @ symbol used in a short message. A widely used alternative
is typing "*" as defined in GSM 03.40 (GPP TS 23.40).
•
All characters entered behind the prompt ">" will be recognized as GSM characters. For example, "Backspace" (ASCII character 8) does not delete a character, but will be inserted into the short message as an additional physical character. As a result, the character you wanted to delete still appears in the text, plus the GSM
code equivalent of the Backspace key.
•
In text mode, the maximum length of an SMS depends on the used coding scheme: It is 160 characters if the
7 bit GSM coding scheme is used, and 140 characters according to the 8 bit GSM coding scheme.
•
At baudrates lower than 19200 it is recommended to use the line termination character only (refer to <n> of
ATS3, default <CR>) before entering text or PDU. Use of the line termination character followed by the
response formatting character (see <n> of ATS4, default <LF>) can cause problems.

Command Description
The write command selects the procedure how the receipt of new SMS messages from the network is indicated
to the TE when TE is active, e.g. DTR signal is ON. If TE is inactive (e.g. DTR signal is OFF), message receiving
should be done as specified in GSM 03.38. If the DTR signal is not available or the state of the signal is ignored

Parameters <mt>=2,3 and <ds>=1 are only available with GSM phase 2+ (see AT+CSMS=1). Incoming SMs
or Status Reports have to be acknowledged with AT+CNMA=0 when using these phase 2+ parameters.
•
If the ME operates on different instances (MUX channels 1, 2, 3) 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.
•
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

Notes
•
The Mobile Equipment storage ''ME'' offers space for 25 short messages, see <mem1>.
•
''MT'' is the sum of ''ME'' (= 25 locations) and ''SM'' (capacity varies with SIM card). 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, MC35i 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.
•
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.
•
The indices <index> of the storage are dependent on the order selected with AT^SSMSS.

Command Description
The write command selects values for additional parameters needed when SM is sent to the network or placed
in a storage when text format message mode is selected.
It is possible to set the validity period starting from when the SM is received by the SMSC (<vp> is in range 0...
255) or define the absolute time of the validity period termination (<vp> is a string). The format of <vp> is given
by <fo>. If TA supports the enhanced validity period format, see GSM 03.40), it shall be given as a hexadecimal
coded string (e.g. <pdu>) with quotes.

Command Description
The execute command is the same as the write command, but uses the given default of <stat>.
The write command allows to select a status type and lists, from the message storage <mem1>, all messages
that currently have the specified <stat>. The major difference over the standard command AT+CMGL is that the
status of the listed messages remains u n c h a n g e d (unread remains unread).
Notes
•
The selected <mem1> can contain different types of SMs (e.g. SMS-DELIVERs, SMS-SUBMITs, SMS-STATUS-REPORTs and SMS-COMMANDs), the response may be a mix of the responses of different SM types.
TE application can recognize the response format by examining the third response parameter.
•
This command can be used only after the SMS data from the SIM have been read successfully for the first
time. Reading starts after successful SIM authentication has been performed, and may take up to 30 seconds
depending on the SIM used. While the read process is in progress, an attempt to use any of the sms read
commands will result in ''+CME Error: 14'' (SIM busy)

that both buffers (''ME'' and ''SM'') are full.

The AT Commands described in this chapter are related to the Subscriber Identity Modul (SIM) connected to the
MC35i.
13.1
AT+CRSM Restricted SIM Access
AT+CRSM allows the TE to access the Elementary Files on the SIM. Access to the SIM database is restricted to
the commands which are listed at <command>.
All parameters of AT+CRSM are used as specified by GSM 11.11 [21].
As response to the command the MC35i sends the current 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, errors related to SIM data are reported in <sw1> and <sw2> parameters as defined in GSM
11.11 [21].
AT+CRSM requires PIN authentication. However, using <command> "READ BINARY" and <command> "READ
RECORD" is possible before PIN authentication and if the SIM is blocked (state after three failed PIN authentication attempts) to access the contents of the following Elementary Files:

The write command enables or disables the presentation of URCs to report whether or not the SIM card is connected.
If the ME is powered down or reset (AT+CFUN or AT^SMSO) the current presentation mode setting <mode> will
not be retained. Therefore the setting <mode>=1 needs to be restored after power on the MC35i or may be saved
in the user profile (AT&W).

The SIM interface HW has been deactivated to prevent possible damage (e.g.
if a SIM with invalid or unsupported electrical specifications has been
detected).
The SIM interface can be reactivated only with a restart of the module, e.g. with
"AT+CFUN= n,1".
Note
•
<SimStatus> reflects the status of the SIM and the card holder tray. Therefore if an empty SIM card tray is
inserted, two URCs will be presented, indicating the status 1 followed by 0, i.e. a SIM is inserted into the card
holder tray but no SIM connection could be established.
Example
AT^SCKS=1

SIM Application Toolkit (SAT) Commands
This chapter offers a brief reference of commands and responses related to the MC35i's SIM Application Toolkit
(SAT) implementation. Detailed information is available with the document "Remote-SAT User Guide" [5]. 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 MC35i 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 MC35i's SAT from the SIM Application, such as "DISPLAY TEXT".
•
Envelope Commands are responded to the SIM Application from the MC35i, such as "MENU SELECTION".

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 MC35i
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.

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.

^SSTN SAT Notification
Reference(s)
SIEMENS
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.

15. Phonebook Commands
15.
mobile
Phonebook Commands
The AT Commands described in this chapter allow the external application to access the phonebooks located in
the MC35i's memory or on the attached Subscriber Identity Modul (SIM).
15.1
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.

AT+CPBR Read from Phonebook
This command serves to read one or more entries from the phonebook selected with AT command AT+CPBS.
It can be used only after the phonebook's data has been read from the SIM successfully. Reading starts after
successful SIM authentication has been performed and may take up to 30 seconds depending on the SIM used.
While this read process is in progress, an attempt to use any of the phonebook commands will result in "+CME
Error: SIM busy". To determine when the initial phonebook reading has been finished the URC "^SSIM READY"
shall be used, refer AT^SSET.

The 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 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.

<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]. As a worst case the number of UCS2 characters is less than half the number of GSM characters. For a detailed description please refer to GSM 11.11, Annex
B [21].

AT^SPBC Search the first entry in the sorted telephone book
This command can be used to retrieve the index of the first entry starting with selected character <schar> in the
sorted list of phonebook records of the phonebook currently selected with AT+CPBS.
The sorted list of phonebook records can be accessed with AT command AT^SPBG. The sort order is described
in Section 15.1, Sort Order for Phonebooks.
CAUTION: Please note that the sorted entries are assigned an index of their own which is not identical with the
location numbers used in the various phonebooks. Therefore, the index retrieved with command AT^SPBC command can be used only as an index for AT^SPBG. Do not use the listed index numbers to dial out or modify
entries.
This command can be used only after the phonebook data from the SIM have been read successfully for the first

AT^SPBD Purge phonebook memory storage
This command is used to purge the selected phonebook <storage> manually, i.e. all entries previously stored
in the selected phonebook storage will be deleted.
CAUTION! The operation cannot be stopped nor reversed!
Automatic purging of phonebooks is performed when the SIM card is removed and replaced by a different SIM
card. This affects the ME-based part of the "LD" storage, and storages "MC" and "RC". Storage "ME" is not
affected.
For unsuccessful automatic call attempts, a "blacklist" functionality according to GSM02.07, Annex A is implemented. Since the module cannot determine whether user interaction is taking place, the blacklist must be
deleted by the application, when applicable. This can be done using command AT^SPBD with parameter "BL".
This command can be used only after the phonebook data from the SIM have been read successfully for the first
time. Reading starts after successful SIM authentication has been performed, and may take up to 30 seconds
depending on the SIM used. While the read process is in progress, an attempt to use any of the phonebook commands will result in "+CME Error: 14" (SIM busy).

AT^SPBG Read current Phonebook entries
This command can be used to display the phonebook records of the phonebook currently selected with AT+CPBS
in sorted order by name. The sort order is described in Section 15.1, Sort Order for Phonebooks.
There are two ways to use command AT^SPBG:
•
If the optional parameter <RealLocReq> is omitted: Please note that the sorted entries are assigned an
index of their own which is not identical with the location numbers used in the various phonebooks.
In this case, command AT^SPBG can be used for reading only. For example, it helps you find entries starting
with matching characters. Do not use the listed index numbers to dial out or modify entries.
•
To access an entry found with AT^SPBG for editing or dialing, enter AT^SPBG with the parameter <RealLocReq>=1.
Then extract the "real" location number of the entry from response parameter <location> and use this
"real" location number with ATD><mem><n> or AT+CPBW.
This command can be used only after the phonebook data from the SIM have been read successfully for the first
time. Reading starts after successful SIM authentication has been performed, and may take up to 30 seconds
depending on the SIM used. While the read process is in progress, an attempt to use any of the phonebook commands will result in "+CME Error: 14" (SIM busy).

Command Description
The test command returns the index range for this command, the maximum length of <number> field, and the
maximum length of <text> field.
Note: The length may not be available while SIM storage is selected. If storage does not offer format information,
the format list should be empty parenthesises.
The write command selects the index of the phonebook entry, that is to be displayed, in the sorted list of phonebook, or the range of indices to display.
If no <index2> is given, only the entry at <index1> will be displayed.
If parameter <RealLocReq>=1, the actual location of the entry displayed will be indicated in parameter <location>. If <RealLocReq> is omitted or <RealLocReq>=0, parameter <location> will not be displayed.
The indices displayed in the first parameter of the write command response are indices in the sorted list of
entries, and not related to the entries' location in the phonebook. They may not be used for other phonebook
commands or ATD><mem><n>. Instead, parameter <location> must be used for these purposes.
Parameter Description
<index1>(num)
The first index number within the sorted list of phonebook for which the corresponding entry is to be displayed.
The supported range is given in the test command response.
If <index 1> exceeds the upper bound <used>, the AT command will return a CME ERROR 21.
<index2>(num)
The last index number within the sorted list of phonebook for which the corresponding entry is to be displayed.
The supported range is given in the test command response.
If both <index1> and <index2> are in the range indicated by the test command in parameter <used>, the list
of entries will be output and terminated with OK.
If <index2> exceeds the range indicated by the test command in parameter <used>, the list of entries will be
output but terminated with a +CME ERROR 21 "INVALID INDEX".
<RealLocReq>(num)
Is a display of the "real" <location> of the entry required?
[0]
Do not display an entry's "real" location number. Parameter <location> will
not be displayed.

As an alternative to AT+CLVL, you can use AT^SNFO and AT^SNFV. The parameter <level> is identical with
<outStep> used by both commands.
•
Any change to <level> (or <outStep>) takes effect in audio modes 2 to 6. That is, when you change
<level> (or <outStep>) and then select another mode with AT^SNFS, the same step will be applied.
The only exception is audio mode 1 which is fixed to <level>=4 (or accordingly <outStep>=4).
•
<level> (or <outStep>) is stored non-volatile when the ME is powered down with AT^SMSO or reset with

The Write command is intended to send ASCII characters or strings which cause the Mobile Switching Center
(MSC) to transmit DTMF tones to a remote subscriber. It works during active voice calls only and offers the following variants:
•
AT+VTS=<dtmfString> allows to send a sequence of DTMF tones with a duration defined with AT+VTD.
•
AT+VTS=<dtmf>[,<duration>] allows to send a single DTMF tone. In this case, the duration can be indvidually determined during the call.

Notes
•
The AT^SAIC write command is usable only in audio modes 2 - 6. If AT^SNFS=1, any attempt to use the
AT^SAIC write command returns "+CME ERROR: operation not allowed". This is because all default parameters in audio mode 1 are determined for type approval and are not adjustable.
•
To allocate a specific audio mode to one of the audio interfaces, first select the audio mode with AT^SNFS
and then choose the interface using AT^SAIC.
•
The factory defaults of AT^SAIC vary with the selected audio mode.
If AT^SNFS=1 or 4 or 5, then AT^SAIC=2,1,1.
If AT^SNFS=2 or 3 or 6, then AT^SAIC=2,2,2. (Although given by default, this setting applies to the MC35i
module only, it cannot be used with the MC35i Terminal where the second audio interface is not connected.
Nevertheless, you can configure MC35i Terminal for operation with audio modes 2, 3 or 6 by setting
AT^SAIC=2,1,1 instead. See examples provided with AT^SNFS.)
AT^SNFD can be used to reset the factory defaults.
•
For use after restart of the ME, you are advised to store the settings of AT^SAIC and AT^SNFS to the audio
profile set with AT^SNFW. Otherwise, audio mode 1 (AT^SNFS=1) and audio interface 2 (AT^SAIC=2,1,1) will
be active each time the ME is powered up.

<outCalibrate> specifies the amount of volume of each <outStep>. The range of each <outCalibrate> is up to 65535, but will be suppressed to 32767. A value above <outCalibrate>= 65535 will cause
an error.
•
The range of <sideTone> is up to 65535, but will be suppressed to 32767. A value above <sideTone>=
65535 will cause an error.
•
Any change to <outStep> takes effect in audio modes 2 to 6. That is, when you change <outStep> and
then select another mode with AT^SNFS, the same step will be applied. Nevertheless, the sound quality and
the amount of volume are not necessarily the same, since all remaining audio parameters can use different
values in either mode.
•
Audio mode 1 is fixed to <outStep>=4. In this mode, any attempt to change <outStep> or other parameters
returns an error.
•
The value of <outStep> is stored non-volatile when the ME is powered down with AT^SMSO or reset with
AT+CFUN=x,1. Any other parameters changed with AT^SNFO need to be saved with AT^SNFW for use after
restart. See also AT^SNFD for details on restoring factory defaults.
•
The values of <outStep> can also be changed with AT^SNFV and AT+CLVL.
•
CAUTION! When you adjust audio parameters avoid exceeding the maximum allowed level. Bear in mind that

Command Description
The write command serves to set the audio mode required for the connected equipment. For use after restart of
the module, you are advised to store the selected mode to the audio profile set with AT^SNFW. Otherwise, audio
mode 1 will be active each time the module is powered up.
AT^SNFS can also be used in conjunction with AT^SAIC. This is useful, for example, if the audio interfaces are
operated alternatively to benefit from different devices. Each audio mode can be assigned a specific interface.
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.

Audio mode 1: Standard mode optimized for the reference handset, that can
be connected to the analog interface 1 (see your "Hardware Interface Description" for information on this handset.) To adjust the volume use the knob of the
reference handset. In audio mode 4, this handset can be used with user

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 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.

Notes
•
The read and write commands refer to the active audio mode.
•
The write command works only in audio modes 2 to 6!
•
Any change to <outStep> takes effect in audio modes 2 to 6. That is, when you change <outStep> and
then select another mode with AT^SNFS, the same step will be applied. Nevertheless, the actual volume can
be quite different, depending on the values of <outCalibrate> set in each mode. The only exception is
audio mode 1 which is fixed to <outStep>=4.
•
<outStep> is stored non-volatile when the ME is powered down with AT^SMSO or reset with AT+CFUN=1,1.
<outStep> is not stored by AT^SNFW.
•
<outStep> can also be changed by AT^SNFO (Section 16.13, AT^SNFO) and AT+CLVL (Section 16.4,
AT+CLVL).

mobile
The execute command is intended for testing. It starts to play a melody from the audio output currently selected
with the AT^SNFS command. 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 write command chooses the type and volume of ring tones for the selected event. 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.
Before first using ring tones:
We have chosen to let you decide your own preferences when you start using ring tones. Therefore, factory setting is AT^SRTC=3,0,3,0,0 (ring tones are muted). To activate ring tones for the very first time, first enter the write
command and simply change the volume. After applying a firmware update the volume and type selected before
the firmware update will be preserved.
Parameter Description
<type>(num)
Type of ring tone. You have a choice of 7 different ring tones and melodies. All will be played from the audio
output selected with the AT^SNFS command. <type>=0 is only intended for muting.

Unsolicited Result Codes
URC 1
+CALA: <text>
Indicates reminder message.
URC 2
^SYSSTART ALARM MODE
+CALA: <text>
Indicates ME wake-up into Alarm mode. If autobauding is active (AT+IPR=0) the line "^SYSSTART ALARM
MODE" does not appear, but your individual <text> message will be displayed.
Command Description
Test command returns supported array index values <n>, alarm types <type>, and maximum length of the text
<tlength> to be output.
Read command returns the list of current alarm settings in the ME.
The write command sets an alarm time in the ME. When the alarm is timed out and 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.
•
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: ^SYSSTART ALARM MODE. A limited number of AT commands is available during Alarm mode, for details see Table 17.1, List of AT commands available in Alarm mode. 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 . For details please refer to [2].
Parameter Description
<time>(str)
Format is "yy/MM/dd,hh:mm:ss", where characters indicate year (two last digits), month, day, hour, minutes. E.g.
6th of May 2004, 22:10:00 hours equals to "04/05/06,22:10:00" (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 the various Multiplexer channels, for details see notes below.

<type>(num)

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 MC35i is totally disconnected from power supply the most recently saved configuration of +CALA:
<time>[,<n>[,<type>[,<text>]]] will be presented when MC35i is powered up.
•
Each time MC35i 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).
•
Alarm settings on 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 alarm is timed out and executed, 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.
Examples
EXAMPLE 1
You may want to configure a reminder call for May 31, 2004, at 9.30h, including the message "Good Morning".
AT+CALA="04/05/31,09:30:00",0,0,"Good Morning"
OK
Do not switch off the GSM engine. When the alarm is executed the ME returns the following URC:

one phone number (in international format) that can be called even if a critical temperature limit is exceeded.
The number will be stored permanently in the ME. Please refer to Section 17.4.1, Deferred shutdown for more
information about the deferred temperature switchoff. The phone number must be in international format, i.e. it
must begin with the international access character ''+''.
If the use of call modifiers (such as ''G'',''I'' or ''*31#'') is possible when starting a call to <phone number>, the
modifiers must be stored together with the number, and entered every time the number is called. Otherwise, the
number may not be recognized, so a temperature switchoff will not be deferred by the active call.
The maximum length for the number is 41 digits including the mandatory ''+'' sign.
If parameter <phone number> is left out, an already stored number will remain unchanged.
If parameter <phone number> is invalid, an already stored number will be erased.
In order to "orderly" erase a number stored previously as <phone number>, enter an empty string '''' as parameter value.
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. For exceptions please
refer to Section 17.4.1, Deferred shutdown.
The shutdown 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 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 during the two minute guard period after the module was switched on. After
expiry of the two minute guard period, the presentation will be disabled, i.e. no URCs with alert levels ''1'' or
''-1'' 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, except in cases described in Section 17.4.1,
Deferred 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.
Examples
EXAMPLE 1

Deferred shutdown
In the following cases, shutdown will be deferred if a critical temperature limit is exceeded:
•
while an emergency call is in progress
•
while a call to predefined number <phone number> is in progress
•
during a two minute guard period after powerup. This guard period has been introduced in order to allow for
the user to make an emergency call or to make a call to <phone number>. The start of any one of these
calls extends the guard period until the end of the call. Any other network activity may be terminated by shutdown upon expiry of the guard time.
While in a "deferred shutdown" situation, the engine continues to measure the temperature and to deliver alert
messages, but deactivates the shutdown functionality. Once the guard period is expired or the call is terminated,
full temperature control will be resumed. If the temperature is still out of range, ME switches off immediately (without another alert message).
CAUTION! automatic shutdown is a safety feature intended to prevent damage to the module. Extended usage
of the deferred shutdown facilities provided may result in damage to the module, and possibly other severe consequences.

The AT^SSYNC command serves to configure the SYNC pin of the application interface. The applicability of the
different types of <mode> is product dependent:
•
If you have a MC35i module you may select either mode, depending on whether your application is designed

•
In the case of the MC35i Terminal the AT^SSYNC command is intended only to control the status LED placed

17.5 AT^SSYNC
mobile
Parameter Description
<mode>(num)
[0]
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.
Note: <mode>=0 is the factory default of the MC35i module. In the case of the
MC35i Terminal this mode is not applicable and should not be selected.
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 17.5.1, ME status indicated by
status LED patterns.
Note: <mode>=1 is the factory default of the MC35i Terminal.
Note
•
The selected <mode> is stored to the non-volatile Flash memory, and thus retained after Power Down.
17.5.1
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. Except for the LED state "off", all LED patterns apply
no matter whether the ME works at full functionality level AT+CFUN=1 or has entered a "temporary wake-up state"
during one of the CYCLIC SLEEP modes. See AT+CFUN for details on the various SLEEP modes.

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.

19.1
Restricted access to SIM data after SIM PIN authentication
The following commands can be used only after data from the SIM have been read successfully for the first time.
Reading starts after successful SIM authentication has been performed, and may take up to 30 seconds depending on the SIM used. While the read process is in progress, an attempt to use any of the following commands
will result in "+CME Error: 14" (SIM busy).
We recommend to take advantage of the "^SSIM READY" URC. If enabled with AT^SSET, this URC acknowledges to the user that SIM data is accessible after SIM PIN authentication. It will be delivered once the ME has
completed reading data from the SIM card.
