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, TC35i is short for the engine type and
TC35iT 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 the Chapter 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 TC35i 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 chapter 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.

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
•
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 chars).
•
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.
•
TE
TE is the terminal equipment that uses the GSM default alphabet as its character set. MS Hyperterminal
(often used with the module) is an ANSI / ASCII terminal that does not support the GSM default alphabet.
•
Data Coding Scheme
The Data Coding Scheme (dcs) is part of a short message and is saved on the SIM. When writing a short
message to the SIM in textmode, the dcs stored with AT+CSMP is used.
•
TE Character Set
The currently used TE character set is selected with AT+CSCS.
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 are in the range from 0 ... 127. CAUTION:
GSM alphabet is not ASCII alphabet!
Several problems resulting from the use of the GSM alphabet:
•
"@" character with GSM alphabet value 0 is not printable by an ASCII terminal program (e.g. Microsoft©
Hyperterminal®).
•
"@" character with GSM alphabet value of binary 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.

1.6 Flow Control
1.6
mobile
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.
In Multiplex mode, it is recommended to use hardware flow control.
1.6.1
Software flow control (XON/OFF flow control)
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 flow control)
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 once 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 in 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

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"), received SMs, changing temperature, status of the
battery etc.
A summary of all URCs is given in chapter 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 TC35i, for details refer to [4] 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 Chapter 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 Chapter 4.10.1. To avoid problems we recommend to configure a fixed bit rate rather than using autobauding.
1.7.1
Communication between Customer Application and TC35i
Leaving hardware flow control unconsidered the Customer Application (TE) is coupled with the TC35i (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 TC35i 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 TC35i 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 TC35i using activated echo (ATE1), i.e. the TC35i 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 TC35i 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. This is set with the command AT+CMEE.

2.9 AT+CFUN
2.9
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>=7 or 8, since in
these modes TC35i 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 TC35i and
take it back to full functionality. Please refer to section 2.9.1 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.

Command Description
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.
7
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. ME exits SLEEP mode only, if
AT+CFUN=1 is entered.
8
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. ME exits SLEEP mode
only, if AT+CFUN=1 is entered.
To ensure that power saving takes effect immediately, the ME stays active for
only 2 seconds after <fun>=8 was entered.

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 chapter "4.10.1".
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 [4],
chapter "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 TC35i 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]). With AT^SSYNC you can select different modes of LED signalization during SLEEP modes (see 16.6.1 for details). 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.

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:

EXAMPLE 3
To stop CYCLIC SLEEP mode and return to full functionality:
AT+CFUN?

Remember that this approach is not applicable to the NON-CYCLIC SLEEP mode (since the serial interface
is disabled). The NON-CYCLIC SLEEP mode ends with the first wake-up event.
EXAMPLE 4
To reset and restart the ME:
or alternatively, AT+CFUN=0,1 or 5,1 or 6,1 or 7,1 or 8,1
AT+CFUN=1,1
OK
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.

^SHUTDOWN
Indicates that the power-off procedure is finished and the module will be switched off within 1 second
Command Description
The exec command initiates the power-off procedure. Low level of the module's VDD pin and display of URC
"^SHUTDOWN" verifies that the procedure has completed and the module has entered the POWER DOWN mode.
Therefore, be sure not to disconnect the operating voltage until VDD is low or until URC "^SHUTDOWN" is displayed . Otherwise, you run the risk of losing data. For further details on how to turn off the module see the [2].
Notes
•
Do not send any command after this command.
•
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.

Command Description
Write command informs TA which character set <chset> is used by the TE. TA is then able to convert character
strings correctly between TE and ME character sets.
Parameter Description
<chset>(str)
“GSM“(&F)
GSM default alphabet (GSM 03.38 subclause 6.2.1);
Note: This setting may cause software flow control problems since the codes
used to stop and resume data flow (XOFF = decimal 19, (XON = decimal 17)
are interpreted as normal characters.
“UCS2“
16-bit universal multiple-octet coded character set (ISO/IEC10646 [32]); UCS2
character strings are converted to hexadecimal numbers from 0000 to FFFF;
e.g. "004100620063" equals three 16-bit characters with decimal values 65, 98
and 99, $(AT R97)$

<AutoExecATC>(str)(+CSCS)
AutoExec AT command String
This parameter specifies the automatically launched AT command. It is executed as entered online, e.g. command concatenation is possible if supported by the given commands. If serial multiplex mode is activated
(AT+CMUX) the first logical channel is used, i.e. CSD calls (data or fax) could be set up. If the TC35i is busy on
the serial channel command execution will be delayed until ongoing action is finished.
In contrast with AT%D repeated autoexecution events are not ignored during a call triggered by such an event.
The first two characters of the automatically launched AT command shall be "at" and its length shall be less than
25 characters.
Please refer to examples below.
Value will be saved while switching off the TC35i via AT commands (e.g. AT+CFUN or AT^SMSO) and restored
on next power up.
<AutoExecMode>(str)(+CSCS)

Notes
•
Automatic dialing on DTR line activation can also be enabled via AT%D. However, AT%D and <AutoExecType>=0 shall not be used at the same time. If both kinds of DTR triggered autoexecution are enabled only
AT%D related action will be performed.
•
Please keep in mind, that each time the ME is restarted the timers of all autoexec actions configured with
<AutoExecType>=1 and <AutoExecPeriod> will be reinitialized and restarted. As a result, an autoexec
action configured at a time later then a scheduled automatic restart would never be executed.
•
Please be careful using <AutoExecType>=1 with small period values and shutdown or reset AT commands,
since only little time remains to change these settings again after TC35i restart.
•
If <AutoExecATC> uses AT commands containing secret data, this information may be retrieved with
AT^SCFG?. For instance, this applies if using AT+CPIN.

Unsolicited Result Code
+CIEV: <indDescr>, <indValue>
A value of an indicator has changed.
Command Description
The read command returns the URC presentation mode <mode> and among others, the indicator event reporting
status <ind>.
The write command enables and disables the presentation of "+CIEV: <indDescr>, <indValue>" URCs.
<indDescr> refers to the name of a "+CIEV" indicator and <indValue> is the new value of this indicator. All
registered indicator events will be issued to the TE.
Parameter Description
<mode>(num)(&W)

1
Discard "+CIEV" URCs when TA-TE link is reserved, e.g. in online data mode.
Otherwise they are forwarded directly to the TE.
2
Buffer "+CIEV" URCs in the TA while TA-TE link is reserved, e.g. in online data
mode, and flush them to the TE afterwards. Otherwise they are forwarded
directly to the TE.
3
Forward "+CIEV" URCs directly to the TE. If TC35i is in online data mode,
URCs are signaled via sending BREAK (100ms) and stored in a buffer. Once
it is back in command mode e.g. after +++ was entered, all URCs stored in the

Note
•
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.

AT+CIND Indicator control
This command controls information about status changes via URC presentation of the $product; 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 0..4 or 5 if no measuring is performed, e.g because no battery is connected. Also refer AT^SBC.
“signal“
Signal quality (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

3.2 AT+CIND
mobile
“smsfull“
A short message memory storage in the MT has become full (1) or memory
locations are available (0), i.e. range is (0-1)
“rssi“
Received signal (field) strength (0..5) or (99) if not measurable.
0: signal strength <= -112 dbm
1-4: signal strength in 15 dbm steps
5: signal strength >= -51 dbm
Received signal (field) strength can also be obtained with AT+CSQ. However,
the signal strength is scaled to value range 0..31 by this command.
<state>(num)
0
Indicator is deregistered. The indicator will not be presented as "+CIEV" URC,
but can be queried with AT+CIND?.
[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
OK
AT+CIND?
+CIND: 5,99,1,0,0,0,0,0,5
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+CMER=2,0,0,2

Command Description
The 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.
Parameter Description
<indValue>(num)
Integer type value in the range stated below for the corresponding <indDescr>
<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:
“ciphcall“
Ciphering Status Change Indication
As stated in GSM specifications 02.07 and 02.09 the ciphering indicator feature
allows the ME 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 EFADsetting 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, you will get 2 URCs 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.
<Mode>(num)
0
Indicator is deregistered, i.e. no such indicator event report (URC) will be
issued.

Often, the initialization routine of Fax programs includes enabling RTS/CTS
handshake, eliminating the need to issue AT\Q3 once again.
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.
•
Flow control can also be set using AT+IFC.

Command Description
Enable and disable automatic dialling on DTR line activation.
A more generic way to control the TC35i via its DTR line is available with AT^SCFG, refer to parameter <AutoExecATC>.
If automatic dialling is enabled with AT%D and the DTR line switches from OFF to ON state, the ME attempts to
set up an outgoing call to the number stored at the first index of the ''ME'' phone book, or using telephone number
"112" in case of an emergency call.
If enabled, DTR activation triggers a dial command (ATD) as though it were entered by a TE. Therefore if in this
situation characters are entered on the same serial channel the ongoing dial command will be terminated (user
break).
When a call setup starts all other active or held calls are dismissed.
Repeated DTR activation events are ignored while call setup is in progress or during a call established by DTR
activation. Also all DTR activation events during multiplex mode are discarded.

To enable auto dialling for data and voice calls after ME's power on it is necessary to disable PIN authorization
with the command AT+CLCK="SC",0,<password>. To prevent misuse of this unprotected SIM card it is recommended to limit its network facilities. For details refer to the "FD" parameter of AT+CLCK.
If dialling starts on DTR line activation, possible responses are as though the dial command were entered by a
TE, for instance:
•
OK
If successfully connected and voice call
•
CONNECT<text>
If successfully connected and non-voice call. <text> is sent out if parameter setting is ATX>0. TA switches to
data state.
•
+CME ERROR: SIM not inserted
SIM card is needed to set up data and voice calls.
•
+CME ERROR: SIM PIN required
PIN is required to set up data and voice calls.
•
+CME ERROR: not found
Phone book entry is required for data and voice calls, but no telephone number is provided.
•
NO DIALTONE
If there is no dialtone and parameter setting ATX2 or ATX4.
•
BUSY
If busy and parameter setting ATX3 or ATX4.
•
NO CARRIER
If a connection cannot be set up or call is finished by other party.
Parameter Description
<mode>(num)(&W)
Auto dial state on DTR activation (OFF-ON transition).
Additional functionality is available with AT^SCFG, e.g. sending a short message (SMS) on DTR activation can
be done with parameter <AutoExecATC> set to "AT+CMSS=1".
[0](&F)
Disable functionality.
1
Enable dialling of the telephone number located at index "1" in the "ME" phone
book. If <dialType> is "!" an emergency call is set up. Refer to AT+CPBS and
AT+CPBW.
<dialType>(str)(&W)
Determine type of performed dial.
[““](&F)
If omitted performed dial command leads to a data call.
“;“
Performed dial command leads to a voice call.
“!“
Dial command leads to an emergency call, i.e. ATD "112"; is performed. No
SIM card needs to be inserted in this case.
CAUTION!
AT%D1! setting especially in conjunction with AT&W can easily lead to erroneous
emergency call setups.
Notes
•
To suppress arbitrary call releases on DTR deactivation setting of AT&D0 is strongly recommended.
•
If several AT commands are entered on the same line AT%D needs to be the last one.

•
Following settings are supported:
-

-

-
8 bits, even parity, 1 stop bit (AT+ICF=2,1)
-
8 bits, no parity, 1 stop bit (AT+ICF=3)
-
8 bits, odd parity, 1 stop bit (AT+ICF=2,0)
-
8 bits, no parity, 2 stop bits (AT+ICF=1)
•
If 7E1 and 7O1 mode are set with AT+ICF the parity bit will, by default, not be transmitted over the air. If the
remote party requires the parity bit to be transmitted, additional settings must be made via AT^STPB.
•
When using a bit rate of 300 bps there must be a delay of 500ms before entering the next command. At bit
rates of 1200 bps the delay must be 300ms. For higher bit rates use of the default delay is sufficient.
•
TC35i's autobaud feature detects the bit rate currently used by the TE. However, this detection suffers some
limitations described in chapter 4.10.1. If autobauding is enabled, the AT+ICF read command does not show
the current character framing, but the character framing that will be used when autobauding is disabled.
•
For compatibility reasons, the command can be used in Multiplex mode, though the settings will not take
effect. Please note that changes made on multiplex channel 1 will be saved with AT&W and will become active
when restarting the ME after AT^SMSO.
•
To start the multiplexer it is necessary to set the character framing to 8 bits, no parity and 1 stop bit.
•
If a <format> is selected without parity (e.g. <format>=3) and you try to activate a format with parity (e.g.
<format>=2), you need to explixitly set the parameter <parity> (e.g. AT+ICF=2,1). Otherwise you will get
'+CME ERROR: invalid index'. This is because for <format>=3, the parameter <parity> is set to the internal value 'no parity' which is not supported by <format>=2. (Remember that if an optional parameter is omitted for which no default is stated in this specification, the value of the parameter remains unchanged).

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 chapter 4.10.1).

Notes
•
The 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 new 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 combinations with other commands on the
same command line cannot be avoided, the following constraints shall be considered:
-
Avoid combinations with the AT commands listed in chapter 1.4.2.
-
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 bit rate currently used, but the new
bit rate will be stored and becomes active, when the module is restarted.
•
AT+IPR=230400 cannot be used with the terminal version. Autobauding with 230400 bps is available but not
recommended.

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 (factory setting), e.g. 2 stop bits
are not supported for autobaud mode.
-
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.
-
If entering several AT commands on the same line, consider the requirements described above.
-
When autobauding is switched on:
+ only data length, parity and baud rate are automatically detected
+ if using 1 stop bit, AT+ICF=1 should not be used, because it uses 2 stop bits
+ if using 2 stop bits, no combination of AT+ICF should be used, which uses 1 stop bit
•
Terminal version of TC35i shall not use autobauding with baudrates above 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", "^SYSSTART
ALARM MODE" and "^SYSSTART CHARGE-ONLY 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
While TC35i is using autobauding its serial interface can't be switched to multiplex mode via AT+CMUX. If multiplex mode is already enabled neither autobauding nor any fixed baudrate can be selected with AT+IPR.

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 TC35i 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 [4] 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

Subparameters defined in GSM07.07 are adjusted for control and logical channels as follows
0
UIH frames used only (control channel)
Notes
•
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.
•
Multiplexer mode requires character framing to be set to 8 bits, no parity and 1 stop bit. The setting can be
made using (AT+ICF=3).
4.11.1
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 chapter summarizes the concerned commands. For general rules and
restrictions to be considered in Multiplex mode please refer to [4].

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 [4], Chapter
"Escape Sequence".
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).
In Multiplex mode, the write command AT+IPR=<rate> cannot be used.
AT+IPR=0
Multiplex mode cannot be activated while autobauding is enabled.
AT+CALA
On each channel an individual <text> message can be stored. but only one time
setting applies to all channels. This means an alarm <time> set on one of the
channels overwrites the time setting on all remaining channels. Therefore, the total
number of alarm events returned by the read command AT+CALA? will always be
<n>=0, no matter whether individual text messages are stored.
When the alarm is timed out and executed the ME sends the URC only on the
channel where the most recent alarm setting was made. The alarm time will be
reset to "00/01/01,00:00:00" on all channels.
AT+CMEE
Presentation mode can be separately configured for each channel.
AT+CNMA
If Multiplex mode is activated the +CNMI parameter will be set to zero on all channels, if one channel fails to acknowledge an incoming message within the required
time.
AT+CNMI
Phase 2+ parameters can only be used on one channel. The parameter for <mt>
and <ds> on the other channels have to be set to zero. If either a SM or a Status
Report is not acknowledged, all +CNMI parameter will be set to zero on all channels.
AT+CFUN
If the ME is in Multiplexer mode, it is not recommended to activate SLEEP mode
with AT+CFUN=<fun>. The best approach to properly control SLEEP mode in this
case is to issue the PSC messages described in [4], chapter "Power saving control
(PSC)".

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,new password.
•
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.

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 chapters:
Related +CME errors are listed in 2.12.1. For further instructions and examples see AT+CLCK, AT^SLCK,

Command Description
The execute command returns the number of attempts still available for entering the currently required password,
e.g. the PIN, PUK, PH-SIM PUK etc. To check whether or not you need to enter a passworduse commands
AT+CPIN? and AT+CPIN2?.
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.
Parameter Description
<counter>(num)
Number of attempts for the currently required password. This number will be counted down after each failure.
Notes
•
Whenever the required password changes, <counter> changes to reflect that change. Please refer to the
examples below.
•
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.
•
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:
TC35i_ATC_V02.07

•
Outgoing voice, data or fax calls can be made only to numbers stored in
''FD'' phonebook.
Result code depends on the type of the call:
for voice calls, indication is ''+CME Error 257: Call barred''.
for data and fax calls, indication is ''NO CARRIER''.
•
Access to defined Supplementary Services such as Call barring, Call waiting, Call forwarding, Call hold and Multiparty is possible only if the exact corresponding public MMI *# code for the desired service is stored in the fixed
dialing number phone book, and used with ATD.
AT commands for supplementary service control are barred while "FD" lock
is active.
Indication is ''+CME Error 257: Call barred''.
•
Access to Unstructured Supplementary Services (''USSD'') is possible only
if the exact desired USSD string is stored in the fixed dialling number phone
book, and used with ATD.
AT commands for USSD are barred while "FD" lock is active.
Indication is ''+CME Error 257: Call barred''.
•
SMS can be sent only to phone numbers which are stored in the ''fixed dialling numbers'' phonebook ''FD''.
Indication is ''+CMS Error 302: operation not allowed''.

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.

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.

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 chapter 5.1.1.
<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 chapter 5.1.1.
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 chapter 5.1.1.

EXAMPLE 2
To set password used to enable or disable barring of all outgoing calls:
Requests the network to change the password for
supplementary service "call barring".
Ususally this request will affect all barring services,
even though the request is issued for Supplementary
Service BAOC ("Barring of all outgoing calls") only.
Refer to the respective network provider for detail.

Enable text output of CME Error information
AT+CPWD="PS","1111","2222"
(where "1111" = old password and "2222" = new
password)
OK
Password for facility "PS" is now "2222"
AT+CPWD="PS","1111","2222"
Repeat command to provoke error "incorrect password"
+CME ERROR: incorrect password
("1111" is no longer the correct password)
EXAMPLE 4
To specify a new "PS" lock password, after the old password was disabled (e.g. after three failed attempts to
change the "PS" password): use the master phone code.
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
password> to restore the former disabled password.
AT+CPWD="PS","12345678","1111"
OK
Alternatively, without giving a new password:
AT+CPWD="PS","12345678"
(where 12345678 is the Master Phone Code). Deactivates the present phone lock.

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.

7.2 ATD
mobile
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 standardized GSM emergency number (no SIM needed).
<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.
•
To start the ATD command automatically on DTR signal activation AT%D may be used.

Command Description
The write command serves to end one specific call or all calls known to the ME, indicating a specific GSM04.08
release cause specified by the user. The command can be used for voice, fax and data calls in any call status
(i.e. any calls listed by AT+CLCC).
Parameter Description
<cause>(num)
release cause
Release cause from GSM04.08 to be indicated to the network.
The TC35i will release the selected connection(s) with release cause indication "cause" and location "user" (0)
in the "disconnect" protocol message to the GSM Network. It depends on the network whether or not the release
cause will be forwarded to the remote party.

Notes
•
This command works for MT data, fax and voice calls.
•
Autoanswering of CSD data and fax calls is supported on ASC0/Mux1 only.
•
If <n> is set to higher values, the calling party may terminate the call establishment before the call can be
automatically answered.
•
The correlation between ATS7 and ATS0 is important.
Example: ATS7=30 and ATS0=20 may not allow call establishment.
•
Setting is local to the interface. It is allowed to have different settings on different interfaces. In such cases
the interface 'wins', which is idle and uses the smallest <n> value.

This command is only available during a data call. 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.
To prevent the +++ escape sequence from being misinterpreted as data, it must be preceded and followed by a
pause of at least 1000 ms. The +++ characters must be entered in quick succession, all within 1000 ms.

Notes
•
The command must be set before the call comes. By default, when you do not modify the settings, all calls
received without bearer element are assumed to be voice.
•

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.

Notes
•
To some extent, the cell monitoring commands AT^SMOND, AT^MONI, AT^MONP and AT^SMONC cover the
same parameters. The receiving level, for example, can be queried with all three 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.
•
During a connection, not all of the neighbour cell information can be decoded. The following restrictions apply:
-
Information is updated only for neighbour cells that have already been visible at connection setup, and
continue to be included in the list of cells.
-
New neighbour cells added to the list, for example after handover, cannot be displayed until the connection
is released.
•
Parameters not available or invalid are left out. In this case, two consecutive commas are presented. For
example, if <format> equals 1, the resulting response with parameter <cell> unavailable would read:
^SMOND:
<MCC>,<MNC>,<LAC>,,<BSIC>,<chann>,<RxLev>,<RxLev>Full,<RxLev>Sub,<RxQual>,<RxQual>Full,
<RxQual>Sub,<Timeslot>
OK
•
Parameter sets not requested with input parameter <format> will be left out altogether. For example, the
response for <format>= 12 will read:
^SMOND:<TA>,<RSSI>,<BER>
OK
•
For compatibility with earlier products and to support legacy applications, often any input character will stop
the periodic output of the write command. But since this applies only in certain cases (depending on the settings of Chapter 4.10, page 100 and Chapter 4.11, page 103), it is recommended to always use "at" or "AT".

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.
8.7.3
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 Chapter 4.10, page 100 and Chapter 4.11, page
103).

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

These delivery defaults cannot be recalled automatically.
•
When starting a call with ATD, Parameter 'G' or 'g' of command ATD will have no effect if the option selected
for this single call is identical to the option already selected with AT+CCUG.
•
Current settings are saved in the ME automatically.
•
ATZ or AT&F do not influence the current settings.

•
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 *# 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.
•

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

•
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

•
Otherwise, terminate all held calls (if any).

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.

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.

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.

Command Description
Read command returns the current parameters of PUC.
Write command sets the parameters of Advice of Charge related price per unit and currency table. SIM PIN2 is
usually required to set the parameters.
Parameter Description
<currency>(str)(+CSCS)
Three-character currency code (e.g. "GBP", "EUR"). If the currency name is longer than three characters, all
characters will be cut off after the third position. Before they are written to the SIM Card, these characters are
converted to the standard GSM alphabet.

<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"
OK
Successful
AT+CPUC="EUR","0.10"
+CME ERROR: SIM PIN2 required

Command Description
This command requests the ME to transmit a Phase C page. When the ME is ready to accept Phase C data, it
issues the negotiation responses and the CONNECT result code to the application.
In Phase B, the AT+FDT command releases the ME to proceed with negotiation, and releases the DCS message
to the remote station. In Phase C, the AT+FDT command resumes transmission after the end of a data stream
transmited before.

Format is same for <pdu> in case of SMS, but without GSM 24.11 SC address field and parameter shall be
bounded by double quote characters like a normal string type rarameter
<alpha>(str)(+CSCS)
String type alphanumeric representation of <da> or <oa> corresponding to the entry found in phonebook; implementation of this feature is manufacturer specific
<cdata>(num)
Command Data
GSM 03.40 TP-Command-Data in text mode responses; ME/TA converts each 8-bit octet into two IRA character
long hexadecimal numbers (e.g. octet with integer value 42 is presented to TE as two characters 2A (IRA 50
and 65))

Destination Address
GSM 03.40 TP- Destination-Address Address-Value field in string format; BCD numbers (or GSM default alphabet characters) are converted into characters; type of address given by <toda>
<data>(num)(+CSCS)
User Data
In case of SMS: GSM 03.40 TP-User-Data in text mode responses; format:
• If <dcs> indicates that GSM 03.38 default alphabet is used and <fo> indicates that GSM 03.40 TP-UserData-Header-Indication is not set: ME/TA converts GSM alphabet into current TE character set according to
rules covered in Annex A.
• If <dcs> indicates that 8-bit or UCS2 data coding scheme is used, or <fo> indicates that GSM 03.40 TPUser-Data-Header-Indication is set: ME/TA converts each 8-bit octet into hexadecimal numbers con-taining
two IRA characters (e.g. octet with integer value 42 is presented to TE as two characters 2A (IRA 50 and 65).
In case of CBS: GSM 03.41 CBM Content of Message in text mode responses; format:
• If <dcs> indicates that GSM 03.38 default alphabet is used: ME/TA converts GSM alphabet into current TE
character set according to rules covered in Annex A.

• If <dcs> indicates that 8-bit or UCS2 data coding scheme is used: ME/TA converts each 8-bit octet into hexadecimal numbers containing two IRA characters.
<dt>(num)
Discharge Time
GSM 03.40 TP-Discharge-Time in time-string format: "yy/MM/dd,hh:mm:ss+zz", where characters indicate year
(two last digits), month, day, hour, minutes, seconds and time zone. For example, 6th of May 1994, 22:10:00
GMT+2 hours equals "94/05/06,22:10:00+08"
<ieia>(num)
IEIa (Information Element Identifier octet) of the concatenated SMS.
8
Concatenated short messages, 8-bit reference number
16
Concatenated short messages, 16-bit reference number
<index>(num)
Integer type; value in the range of location numbers supported by the associated memory
<length>(num)
Message Length
Integer type value indicating in the text mode (AT+CMGF=1) the length of the message body <data> (or
<cdata>) in characters; or in PDU mode (AT+CMGF=0), the length of the actual TP data unit in octets (i.e. the
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.
For concatenated SMS messages the maximum length will be reduced by the length of the user data header
with respect to <ieia> (6 bytes for <ieia>=8 and 7 bytes for <ieia>=16). In the case of 8-bit data, the maximum length of the short message field is: 140 octets - (6 or 7) = 134 or 133. In the case of GSM 7 bit default
alphabet data, the maximum length of the short message is (140 - (6 or 7))*8/7 = 153 or 152 characters. In the
case of 16 bit UC2 data, the maximum length of the short message is: (140 - (6 or 7))/2)= 67 or 66 characters.
<max>(num)
Maximum number of all segments to be concatenated into one SMS, beginning with 1.
<max>=0 means: ignore the value. This will result in a non-concatenated SMS.

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.
•
Filler "FF" will not be displayed in PDU status reports if parameter <ff> 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
(V.25ter command AT&D0), reliable message transfer can be ensured by using AT+CNMA acknowledgment procedure.
Parameter Description

Requirements specific to Multiplex mode:
In multiplex mode (AT+CMUX=0) only one channel can use a phase 2+ parameter. The parameter for <mt>
and <ds> on the other channels have to be set to zero. If either a SM or a Status Report is not acknowledged,
all AT+CNMI parameter in all channels will be set to zero.
•
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.
•
Filler "FF" will not be displayed in PDU status reports if the parameter <ff> of AT^SSCONF command is set
to 1.
•
If either a SM or a Status Report is not acknowledged, all AT+CNMI parameters in all channels will be set to
zero.
•
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.

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, TC35i 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>

When <mem3> is switched over from ''MT'' to ''SM'' all free ''ME'' locations will be filled with dummy short messages. This procedure can take up to 35 seconds, until all the 25 records are written.
If switching from ''MT'' to ''SM'' was not finished due to error or user break, the value of <mem3> remains ''MT'',
but some of the dummy records remain in the ''ME'' storage. These records have to be deleted manually.
When <mem3> equals ''SM'', do not delete the dummy messages in the ''ME''. storage. They will be automatically deleted when you switch back from ''SM'' to ''MT''. Again, this may take up to 35 seconds.
If switching from ''SM'' to ''MT'' was not finished due to an error or user break, the value of <mem3> remains
''SM'', but the ''ME'' storage will no longer be filled with dummy records. New incoming short messages may
now be written to the ''ME'' storage, if ''SM'' is already full. To avoid this, repeat the AT+CPMS command as
soon as possible to switch <mem3> back to ''MT''. As an alternative, you can manually delete the dummy
records and issue AT+CPMS=MT,MT,MT.
•
Multiplexer: In Multiplex mode or when the two physical serial interfaces are connected, the parameter
<mem3> will be the same on all instances, but the settings of <mem1> and <mem2> may vary on each channel
/ interface. As a result, changes on parameter <mem1> and/or <mem2> befor activating the multiplexer or differences values for other instanes can result in not desired behaviours like different outputs for AT+CMGL and
so on.
•
While <mem3> equals ''SM'' and <mem1> equals ''ME'' it is possible that, after deleting short messages from
''ME'', the freed space on ''ME'' is reclaimed for new incoming short messages, when there is no space left on
the ''SM'' storage. As it is often the clients concern to have received short messages stored only to the SIM

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)

SIM Application Toolkit (SAT) Commands
This chapter offers a brief reference of commands and responses related to the TC35i's SIM Application Toolkit
(SAT) implementation. Detailed information is available with the document "Remote-SAT User Guide" [3]. Please
contact the Wireless Modules Application Engineering Department at Siemens AG for details.
ETSI specification GSM 11.14 [19] 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 TC35i 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 TC35i's SAT from the SIM Application, such as "DISPLAY TEXT".
•
Envelope Commands are responded to the SIM Application from the TC35i, such as "MENU SELECTION".

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 TC35i 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

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.

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.

14. Phonebook Commands

mobile
Phonebook Commands
The AT Commands described in this chapter allow the external application to access the phonebooks located in
the TC35i's memory or on the attached Subscriber Identity Modul (SIM).
14.1
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.

Command Description
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.

Phone number with format specified by <type>. Parameter must be present, although it may be an empty
string. However, alphabetic characters are not permitted.
<number> may contain printable non-alphabetic characters of the standard GSM alphabet as dialstring modifiers, including "*", "#" or "+". However, if <number> contains modifiers other than "*", "#" or "+" the following constraints shall be considered:
• If no <type> was specified explicitly, all accepted modifiers from the GSM alphabet will be saved in the number string. <type> will be set to 209 (ASCII). However, limitations as listed below for <type> 209 apply.
• A <number> saved with <type>=209 requires double memory. In order to fit into a standard location, the
number needs to be reduced to a maximum length of <nlength>/2, including all digits and dial string modifiers. Extended locations may be used as stated below for <nlength>.
<type>(num)
Type of address octet
If <type> is specified as 129 or 145, any non-digit characters other than "*", "#", or "+" will be removed from the

Command Description
Test command returns a list of supported <value>.
Every time the write command is executed, 3 rows of phone book records are returned. Each triplet overlaps with
the next one. The actual index depends on parameter <value>. This parameter determines whether the index
will be increased or decreased.
If the index in one output line reaches the last index in the alphabetical list, the next output line will display the
first list entry.
After the last record of the phonebook has been reached (see parameter <used> for AT^SPBG), the <internal-counter> switches over to the first.
See examples below.

Notes
•
The complete list of sorted entries can be retrieved using AT command AT^SPBG.
•
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.
Example
How to use AT^SPBS to browse through the sorted list forward and backward

•
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 TC35i
module only, it cannot be used with the TC35i Terminal where the second audio interface is not connected.
Nevertheless, you can configure TC35i 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.

•
It is not allowed for audio device 1
•
As long as the microphone is muted, the write command is temporarily disabled
•
Setting of value 0 is not allowed (use AT^SNFM=0 for this).
•
For values greater than 32767, 32767 will be used.

Multiplication factor for the sidetone gain.
Formula to calculate how much of the original microphone signal is added to the earpiece signal:
Sidetone gain in dB = 20 * log (sideTone / 32768).
0...32767
Notes
•
The write command works only in audio modes 2 to 6.
•
The read and write commands refer to the active audio mode.
•
<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
exposure to excessive levels of noise can cause physical damage to users!

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 both 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.

Parameter Description
<audMode>(num)(^SNFW)
[1]
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
defined parameters.
Note: The default parameters are determined for type approval and are not
adjustable with AT commands.
AT^SNFD restores <audMode> 1.
2
Audio mode 2: Customer specific mode for a basic handsfree device (Siemens
Car Kit Portable).
Analog interface 2 is assumed as default.
3
Audio mode 3: Customer specific mode for a mono-headset.
Analog interface 2 is assumed as default.
4
Audio mode 4: Customer specific mode for a user handset.
Analog interface 1 is assumed as default.
5
Audio mode 5: Customer specific mode.
Analog interface 1 is assumed as default.
6
Audio mode 6: Customer specific mode.
Analog interface 2 is assumed as default.
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.

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.

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: AT+CCLK, AT+CALA, AT^SBC, AT^SCTM, AT^SMSO.
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 drive the ignition line (IGT pin of application interface) to ground. If your
ME is battery powered note that the battery can be charged while the ME stays in Alarm mode. For details
please refer to [2].
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)

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 TC35i is totally disconnected from power supply the most recently saved configuration of +CALA:
<time>[,<n>[,<type>[,<text>]]] will be presented when TC35i is powered up.
•
Each time TC35i 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:

AT^SBC Battery charging / discharging and charge control
Responses returned by the AT^SBC command vary with the operating mode of the ME:
•
Normal mode: ME is switched on by Ignition pin and running the SLEEP, IDLE, TALK or DATA mode. Charger
is not connected. AT^SBC can be used to query the battery capacity and the power consumption of ME and
application (if value of application was specified before as <current>).
•
Normal mode + charging: Allows charging while ME is switched on by Ignition pin and running the SLEEP,
IDLE, TALK or DATA mode. AT^SBC returns charger status and power consumption of ME / application. Percentage of battery capacity is not available.
•
Charge-only mode: Allows charging while ME is detached from GSM network. When started, the mode is indicated by the URC ''^SYSSTART CHARGE-ONLY MODE''. AT^SBC returns charger status and power consumption of ME / application. Percentage of battery capacity is not available. In Charge-only mode a limited
number of AT commands is accessible (see 16.3.1). There are several ways to activate the Charge-only
mode:
•
-
from Power Down mode: Connect charger while ME was powered down with AT^SMSO
-
from Normal mode: Connect charger, then enter AT^SMSO.
Alarm mode: The battery can be charged while the ME stays in Alarm mode.
Charging begins once the charger connects to the POWER pins of the ZIF connector (except for the Alarm

Unsolicited Result Codes
URC 1
Undervoltage and overvoltage conditions will be reported by unsolicited result codes. The URCs need not be
activated by the user, but will be output automatically when fault conditions occur. For further details regarding
automatic shutdown and voltage ratings please refer to [2].
^SBC: Undervoltage
The URC will be reported, for example, when you attempt to make a call while the voltage is close to the critical limit and further power loss is caused during the transmit burst. To remind you that the battery needs to
be charged soon, the URC appears several times in a minute before the module switches off. If the voltage
drops quickly down to a value which is 50mV below the minimum threshold only one URC will be presented.
URC 2
^SBC: Overvoltage warning
This URC is an alarm indicator displayed when the supply voltage approaches its maximum level. The URC
appears only once.
URC 3
^SBC: Overvoltage shutdown
This URC will be reported when the voltage exceeds the maximum level specified in the Hardware Interface
Description. It appears only once before the module starts to perform an orderly shutdown.
In applications powered from Li-Ion batteries the incorporated protection circuit typically prevents overcharging, thus eliminating the risk of overvoltage conditions. Yet, in case of charging errors, for example caused by
a bad battery or due to the absence of a battery protection circuit, the module's overvoltage shutdown function
will take effect to avoid overcharging.
The automatic shutdown procedure caused by undervoltage or overvoltage is equivalent to the power-down
initiated with the AT^SMSO command, i.e. ME logs off from the network and the software enters a secure state
avoiding loss of data. When the module is in IDLE mode it takes typically one minute to deregister from the
network and to switch off.
Command Description
Use the write command to specify the power consumption of your external application. This information enables
the ME to calculate the average power consumption <mpc> and to properly control the charging process. If the
value is not correct the entire charging process may be affected. Resulting problems may be wrong responses
to the AT^SBC read command, overcharging, or the battery does not reach full capacity.
When the ME is powered down or reset, the value of <current> is restored to its default.

<bcl>(num)
Battery capacity
0, 20, 40, 60, 80, 100 percent of remaining capacity (6 steps)
0 indicates that either the battery is exhausted or the capacity value is not available
While charging is in progress (charging adapter connected) the battery capacity is not available. Consequently,
parameter <bcl>=0. To query the battery capacity disconnect the charger.
<mpc>(num)
Average power consumption.
Value (0...5000) of average power consumption (mean value over a couple of seconds) in mA.
<mpc> is obtained from the ME's power consumption, plus the value you have specified for the application by
using the write command AT^SBC=<current>. Remember that the ME's power consumption varies with its
operating mode (IDLE, TALK, DATA) and the power level.
If <current> was not yet specified and no battery pack NTC is detected <mpc> returns only the module's
present power consumption.
If <current> was not yet specified, but the NTC of the connected battery pack is detected, an offset value of
200mA will, by default, be added. 200mA is an estimated value which represents the power consumption of a
typical external application. Drawn from practical experience it serves as a precaution to ensure proper charging
in case you have not entered <current>. It is strongly recommended that you enter the correct power consumption of your application as described below.
Note: If the battery does not incorporate an NTC, or the battery and the NTC are not compliant with the requirements specified in [2], the battery cannot be detected by the ME.
<current>(num)
Enter the current consumption of your application in mA (0...5000). If used, the current provided over the by 2.9V
VDD pin of the application interface (maximum 10mA) must be added, too.
Notes
•
If Multiplex mode is active, any virtual channel can be used to enter the write command and to specify <current>. The undervoltage URC appears simultaneously on all three channels.
•
The URC ''^SYSSTART CHARGE-ONLY MODE'' is indicated automatically when the engine enters this mode
(except when autobauding is active). Unlike the undervoltage and overvoltage URC, it cannot be disabled or
enabled by the user.

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

AT^SSYNC Configure SYNC Pin
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 TC35i module you may select either mode, depending on whether your application is designed
to use the SYNC mode (indicates the current consumption in a transmit burst) or the LED mode (drives a
status LED connected to the pin). See [2] for further details on both modes.
•
In the case of the TC35i Terminal the AT^SSYNC command is intended only to control the status LED placed
on the front panel. Therefore, the SYNC mode (<mode>=0) is not applicable. Further details on the LED can
be found in [6].

Parameter Description
<mode>(num)

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 TC35i module. In the case of the
TC35i 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 Chapter 16.6.1.
Note: <mode>=1 is the factory default of the TC35i Terminal.
2
LED mode:
Like <mode>=1, but, additionally, enables different LED signalization in SLEEP
mode depending on the status of PIN authentication and network registration.
Notes
•
The selected <mode> is stored to the non-volatile Flash memory, and thus retained after Power Down.
•
Please see AT+CFUN for details on SLEEP mode.

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
