Station), TA (Terminal Adapter), DCE (Data Communication Equipment) or facsimile DCE (FAX modem, FAX board).
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).
1.4
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.
Table 1: Types of AT commands and responses
Test command
AT+CXXX=?
Read command
AT+CXXX?
Write command
Execution command
AT+CXXX=<...>
AT+CXXX
The mobile equipment returns the list of parameters and
value ranges set with the corresponding Write command
or by internal processes.
This command returns the currently set value of the
parameter or parameters
This command sets user-definable parameter values.
The execution command reads non-variable parameters
affected by internal processes in the GSM engine.
1.4.1 Using parameters
· Factory defaults are underlined or, if necessary, explicitly stated in the parameter description. A
factory value will be loaded on power-up if the parameter is not storable (for example if not stored
when AT^SMSO is executed, or not stored to the user profile specified with AT&W, or not stored to
the audio profile defined with AT^SNFW). To restore factory defaults use AT&F. A variety of audio
parameters can be reset to their factory defaults using AT^SNFD.
· Optional parameters are enclosed in square brackets, for example [0]. If optional parameters are
omitted, the bracketed value will be used by default. If a parameter is not enclosed in brackets and
no other behavior is stated, the current setting remains unchanged when the parameter is omitted.
· To ensure the correct sequence of optional and mandatory parameters, a comma must be kept for
each omitted parameter that is followed by further parameters. Example:
AT+CPBW=,<number>,<type>,<text> writes a phone book entry to the first free memory location.
AT+CPBW=<index>,<number>,<type>,<text> writes a phone book entry to the memory location
specified by <index>.
· 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.
· In case of using V.25ter commands without giving an optional parameter, its value is assumed to
be 0.

1.4.2 Combining AT commands on the same command line
You may enter several AT commands on the same line. This eliminates the need to type the "AT" or
"at" prefix before each command. Instead, it is only needed once at the beginning of the command
line. Use a semicolon as command delimiter.
The 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.

Note: When concatenating AT commands please keep in mind that the sequence of processing may
be different from the sequential order of command input. Therefore, if the consecutive order of
the issued commands is your concern, avoid concatenating commands on the same line.
1.4.3 Entering successive AT commands on separate lines
When you enter a series of AT commands on separate lines, leave a pause between the preceding
and the following command until the final response (for example OK, CME error, CMS error) appears.
This avoids sending too many AT commands at a time without waiting for a response for each.

1.5
Supported character sets
The ME supports two character sets: GSM 03.38 (7 bit, also referred to as SMS alphabet) and UCS2
(16 bit, refer to ISO/IEC 10646). See Chapter 4.44 for information about selecting the character set.
Character tables are provided in Chapter 8.5.
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:
1. "@" character with GSM alphabet value 0 is not printable by an ASCII terminal program (e.g. Mi©
®
crosoft Hyperterminal ).
2. "@" 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 Table 3.
By the way, this may be the reason why even network providers often replace "@"with “@=*” in
their SIM application.
3. 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.
4. 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
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. For details please refer to [3].
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. For details refer to Chapter 2.3.
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. For use after restart, AT\Qn should
be stored to the user profile with AT&W.
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.
Note:
After deactivating the RTS line, the ME may still send up to 264 bytes (worst case). This can
be easily managed if the buffer of the host application is sufficiently sized, and if a hysteresis
is implemented in its Rx buffer as mentioned in Chapter 1.6. For host applications that are required to handle a large amount of data at high speed, a total buffer capacity of at least 512
bytes is recommended.

2 Standard V.25ter AT Commands
These AT Commands are related to ITU-T (International Telecommunication Union, Telecommunication sector) V.25ter document.
TC35i supports the registers S0-S29. You can change S0,S3,S4,S5,S6,S7,S8,S10,S18 by using the
appropriate ATSn commands. All the other registers are read-only and for internal usage only!

Response
A/
Repeats previous command line. Line does not need to end with terminating
character.
Parameter
Reference
Note
V.25ter
· After beginning with the character “a“ or „A“, a second character “t“ ,”T“ or “/“
has to follow. In case of using a wrong second character, it is necessary to
start again with character “a“ or “A“.
· If autobauding is active (see Chapter 2.47) A/ (and a/) cannot be used.
2.2
+++ Switch from data mode to command mode
Execute command
Response
+++
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.
OK
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.

Response
AT+IPR?

Parameter
See write command
Write command
AT+IPR=<rate>
This command specifies the DTE-DCE bit rate. When you set a fix 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.
A selected bit rate takes effect following the issue of any result code associated
with this command (e.g. OK).
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 (+IPR=0) the
detected DCE bit rate will not be saved and, therefore, re-synchronized after restarting the GSM engine (see Chapter 2.47.1).

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 4800 bps.
Reference
Note
V.25ter
Factory setting is AT+IPR=0 (autobauding). It cannot be restored with AT&F. The
current setting will be preserved when you download new firmware or when the
ME is powered down.
TC35i_ATC_V00.01

10.01.2003
TC35i AT Command Set
PRELIMINARY
Generally, AT+IPR=x should be used as a standalone command. If nevertheless
combinations with other commands on the same line cannot be avoided, there are
several constraints to be considered:
· Avoid combinations with the AT commands listed in Chapter 1.4.2.
· Take into account that a delay of 100 ms is required between a 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 at the new bit rate and thus, not properly transmitted. The following commands will be correctly sent at the new bit rate.
2.47.1 Autobauding
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 issue an "AT" or "at" string. This is
necessary
· after you have activated autobauding
· when you start up the module 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
(ATS0¹0).
Restrictions on autobauding operation
· The serial interface has to be operated at 8 data bits, no parity and 1 stop bit (factory setting).
· The A/ command (and a/) cannot be used.
· Only the strings “AT“ or “at“ can be detected (neither “aT“ nor “At“).
· Unsolicited Result Codes that may be issued before the ME detects the new bit rate (by receiving
the first AT command string) will be sent at the previously detected bit rate.
· The Unsolicited Result Codes "^SYSSTART" and "^SYSSTART ALARM MODE" are not indicated
when you start up the ME while autobauding is enabled.
· It is not recommended to switch to autobauding from a bit rate that cannot be detected by the autobaud mechnism (e.g. 300 baud). Responses to +IPR=0 and any commands on the same line might
be corrupted.
· When entering several AT commands on the same line, consider the requirements described in the
Notes of Chapter 2.47.
· See also Chapter 2.46.
Autobauding and bit rate after restart
The most recently detected bit rate cannot be stored when TC35i is powered down (with AT^SMSO).
Therefore, TC35i will use 57600 bps by default, until the first AT character was transmitted and the bit
rate was correctly detected.
For example, URCs generated after restart will be output with 57600 bps. The same applies to
autoanswer calls if SIM PIN1 authentication is done automatically and autoanswer mode ATS0¹0 is
stored to the user profile determined with AT&W (if not stored to the user profile ATS0 is reset to its
default 000 after restart and thus not relevant for autobauding).
Autobauding and multiplex mode
If autobauding is active you cannot switch to multiplex mode (see Chapter 4.28). Vice versa, when you
run the multiplex mode, the write command AT+IPR=<rate> cannot be used.

3 AT Commands for FAX
The following commands can be used for FAX transmission. If the ME is acting as a Fax modem to a
PC-based application (e.g. “WinFax“) it is necessary to select the proper Service Class (Fax Class)
provided by the ME. The ME reports its Service Class capabilities, the current setting and the range of
services available. This is provided by the AT+FCLASS command (see pg. 50).
Note: When sending a FAX with a standard FAX application for Personal Computers it is recommended to use autobauding (AT+IPR=0).

Read command
AT+FBADLIN?
This command defines the “Copy-Quality-OK”-threshold. If <badline> consecutive lines have pixel count errors in normal resolution (98 dpi) mode, then the
copy quality is unacceptable. If <badline> * 2 consecutive lines have pixel count
errors in fine resolution (196 dpi) mode, then the copy quality is unacceptable.
“Copy Quality Not OK” occurs if either the error percentage is too high or too
many consecutive lines contain errors. A value of 0 implies that error checking
is not present or disabled.

If error is related to ME functionality:
+CME ERROR: <err>
Parameter
See write command
Write command
AT+CALA=<time>
[,<n>[,<type>
[,<text>]]]
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
(pg. 196). 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. For details please refer to [1].
Response
OK
If setting fails:
+CME ERROR: <err> Refer to Chapter 8.1.1, pg. 231, for <err> values.
TC35i_ATC_V00.01

PRELIMINARY
Parameter
<time>
string type value; format is "yy/MM/dd,hh:mm:ss", where characters
th
indicate year (two last digits), month, day, hour, minutes. E.g. 6 of
May 2003, 22:10:00 hours equals to “03/05/06,22:10:00" (see also
AT+CCLK in Chapter 4.7). Note: if <time> equals current date and
time or is to an earlier date, TA returns +CME ERROR: <21>.
<n>
integer type value indicating the array index of the alarm. Index starts
with 0. If only this value is returned by the test command, it is default
and indicates that only one alarm time is possible; however, if a second alarm time is set, the previous alarm is deleted.
<type>
integer type value indicating the type of the alarm
0 Alarm indication: text message via serial interface
<text>
string type value indicating the text to be displayed when alarm time
is reached; maximum length is <tlength>. After first connection to
power supply <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 (pg. 196). 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 and thus, saves memory due to the limited
number of flash memory write cycles (e.g. 100.000).
<tlength> integer type value indicating the maximum length of <text>. The
maximum length is 16.
Unsolicited result code
Indicates reminder message:
+CALA: <text>
Indicates ME wake-up into Alarm mode:
^SYSSTART ALARM MODE
+CALA: <text>
If autobauding is active (AT+IPR=0) the URCs ^SYSSTART ALARM MODE
and +CALA: <text> do not appear. Therefore, avoid using Alarm mode in conjunction with autobauding.
Reference
Note
GSM 07.07
· <text> should not contain characters which are coded differently in ASCII
and GSM (e.g. Ä, Ö, Ü), see also Chapters 1.5 and 8.5.
· 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 1s to re-initialize the RTC and to update the current time. Therefore, it is recommended to wait 1s before using
the commands AT+CCLK and AT+CALA (for example 1s after ^SYSSTART
has been output).
· Please consider when using multiplex mode (+CMUX, pg. 105):
- It is possible to use +CALA with every logical channel (1 – 3).
- The total no. of possible alarm events is shared by all channels. If <n> =
0 is returned by the test command, this indicates that only one common

Examples
alarm time is possible for all logical channels.
For every channel a different <text> parameter can be stored.
<text> will be output on the same logical channel the alarm was entered.
If not in multiplex mode, <text> will be output independent of the related
channel.
The read command returns all pending alarms, independent on which
logical channel an alarm was entered. It´s up to the user to identify these
alarms by specific <text>s.
Example 1:
You may want to configure a reminder message for May 31, 2003, at 9.30h, including the message "Good Morning".
Write command:
AT+CALA="03/05/31,09:30:00",0,0,"Good Morning"
OK
Do not switch off the GSM engine. When the alarm is executed the ME returns
the following URC:
+CALA: Good Morning
Example 2:
To set a fresh alarm using the same message as in Example 1, simply enter
date and time. <n>, <type>, <text>, <tlength> can be omitted:
AT+CALA="03/05/31,08:50:00"
OK
When the alarm is executed the URC comes with the same message:
+CALA: Good Morning
Example 3:
To configure the alarm mode, e.g. for May 20, 2003, at 8.30h, enter
AT+CALA="03/05/20,08:30:00"
OK
Next, power down the ME:
AT^SMSO
^SMSO: MS OFF
When the alarm is executed the ME wakes up to Alarm mode and displays a
URC. If available, this line is followed by the individual <text> most recently
saved. If no individual message was saved only the first line appears.

· You can register, disable, enable and erase <reas> 4 and 5 as described
above. However, querying the status of <reas> 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 Chapter 8.4 for a complete list of *# GSM
codes. See also examples below.
· 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.
· <class> 2 (data) comprises all those <class> values between 16 and 128,
that are supported both by the network and the MS. This means, a setting
made for <class> 2 applies to all remaining data classes (if supported). In
addition, you can assign a different setting to a specific class. For example, you can activate Call Forwarding for all data classes, but deactivate it
for a specific data class.
· 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.
4.6.1 Examples: Call forwarding
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).
Example 1
To register the destination number of unconditional call forwarding (CFU) for
the default classes voice, data and fax:
at+ccfc=0,3,"+493012345678",145

TC35i AT Command Set
PRELIMINARY
Notes regarding <class>:
· The AT+CCWA command offers a broad range of options according to the
GSM specifications. However, when you attempt to set a <class> which is
not provisioned or not supported for Call Waiting, the setting will not take effect regardless of the response returned. The responses in these cases vary
with the network (for example “OK”, “Operation not allowed”, “Operation not
supported” etc.). To make sure check the current Call Waiting settings with
<mode>=2.
· <class> 2 (data) comprises all those <class> values between 16 and 128,
that are supported both by the network and the MS. This means, a setting
made for <class> 2 applies to all remaining data classes (if supported). In
addition, you can assign a different setting to a specific class. For example,
you can activate Call Waiting for all data classes, but deactivate it for a specific data class.
· 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).
Unsolicited Result
Codes
If <n>=1 and the Call Waiting service is enabled the following URCs indicate a
waiting call to the TE:

If error is related to ME functionality:

Parameter
See below
Write command
AT+CFUN=
[<fun>[,<rst>]]
The write command 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 level 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 and 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 CYCLIC SLEEP mode is
that the serial interface remains accessible and that packet-switched calls can
be done without exiting the SLEEP mode. Also, NON-CYCLIC and CYCLIC
SLEEP mode provide different ways to wake up the ME. For details see Chapter 4.11.1.
For CYCLIC SLEEP mode (<fun>=5, 6, 7 and 8) 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
[1].
Response

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.

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.
<rst>
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.
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.
[0]
The <rst> parameter can only be used if the serial interface
is enabled. Due to the command syntax, you need to enter
<fun>, followed by <rst>, where <fun> is only a placeholder
and has no effect. See examples below.

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 2.47.
Reference
Note
GSM 07.07
· 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 only while the ME is registered
to the GSM network. If you attempt to activate one of the SLEEP modes
while the ME is deregistered, the selected <fun> level will be set, but power
saving does not work to its full extent. 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 that power saving is on, you can query the status with AT+CFUN?,
if you have chosen CYCLIC SLEEP mode. If available, you can take advantage of the status LED controlled by the SYNC pin. See Chapter 7.48 and
[1]. The LED stops flashing once the module starts power saving.

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

· The AT+CHLD command offers a broad range of options according to the
GSM specifications. However, many of these options are dependent on the
SIM card / service provider. 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). Therefore, a data or fax call cannot be put on hold. But it is possible
to place a voice call on hold in order to accept a waiting data or fax call, and
afterwards to recover the voice call. In this case, the only difference is that
AT+CHLD only puts the voice call on hold, the data or fax call shall be manually accepted (via ATA).
Use the AT+CCWA command to activate the Call Waiting service. The
classes of waiting calls can be easily distinguished if the URC +CCWA:
<number>,<type>,<class>,,<CLI validity> is enabled.
For step-by-step instructions refer to the example below. A description of the
AT+CCWA command can be found in Chapter 4.9.
· The NO CARRIER result code is not displayed when a held call has been disconnected from either party. In order to get an indication of this disconnection,
please refer to AT+CSSN command (see Chapter 4.47).
· In conflicting 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.

4.19 AT+CIND Indicator control
TC35i supports indicator event reporting for the following items: signal quality, service availability,
generation of sound in the ME, indication of unread short messages, full SMS storage, call in progress and roaming activities.
There are two ways to display the status and event reports by indicators:
1. You can directly query the current status of each indicator, simply by using the Read command
AT+CIND?. The Read command returns the status no matter whether the indicator has been registered with the Write command AT+CIND=[<stat>[,<stat>[,...]]].
2. You can take advantage of Unsolicited Result Codes. These are 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:
a) The indicators must be registered with the Write command AT+CIND=[<stat>[,<stat>[,...]]].
By default, all of them are registered each time the ME is switched on. Any URCs you do not
need can easily be excluded if deregistered with <stat>=0.
b) The URC presentation mode must be enabled with AT+CMER (see Chapter 4.26).

Parameter
<fac> Phone security locks:
“SC” SIM (lock SIM cards). SIM requests password upon ME powerup and when this lock command is issued.
<password>: SIM PIN1. The password can be modified with
AT+CPWD or AT^SPWD (see Chapters 4.38 and 7.42).
“PS” Phone locked to SIM card. ME requests password when other
than current SIM card is inserted.
<password>: User defined password. It is needed before the first
use of <fac>”PS and, therefore, must first be specified with
AT+CPWD or AT^SPWD.
“FD” SIM fixed dialing memory: If the mobile is locked to "FD", only
the phone numbers stored to the "FD" memory can be dialed
(depending on the SIM card, usually up to 7 numbers).
<password>: SIM PIN2 (or equivalent authorisation via
AT+CPIN2, see Chapter 4.36.)
If a lock on the SIM fixed dialing memory is active, call related
Supplementary Services such as call barring, call waiting or call
forwarding cannot be accessed via AT command. The response
will be “ +CME ERROR: call barred”. In this case, access to call
related Supplementary Services is possible only if the corresponding public MMI *# code is stored in the fixed dialing number phone book, or by deactivation of the SIM fixed dialing facility
lock)
Note:
TC35i_ATC_V00.01
"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 TC35i module.
Once the Master Phone Code has been acctepted, the mobile is
operational, and the "PS" lock is no longer active. See Chapter
4.35.1 and examples below for further details.

Factory set SIM locks
<password>: Factory set password. See note below.
“PF” lock Phone to the very First SIM card
“PN” Network Personalisation
“PU” Network subset Personalisation
“PP” Service Provider Personalisation
“PC” Corporate Personalisation
Note:
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 end user 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 of the TC35i
modules 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.
See Chapter 4.35 and 4.35.1 for further instructions.
Supplementary Service: Call barring:
<password>: Network dependent password. See note below.
“AO” BAOC (Bar All Outgoing Calls)
“OI” BOIC (Bar Outgoing International Calls)
“OX” BOIC-exHC (Bar Outgoing International Calls except to Home
Country)
“AI” BAIC (Bar All Incoming Calls)
“IR” BIC-Roam (Bar Incoming Calls when Roaming outside the home
country)
“AB” All Barring services (applicable only for <mode>=0)
“AG” All outGoing barring services (applicable only for <mode>=0)
“AC” All inComing barring services (applicable only for <mode>=0)
Note:
The availability of the Supplementary Services varies with the
network. To benefit from call barring services the client will need
to subscribe them, though a limited number of call barring types
may be included in the basic tariff package. Call barring is protected by a password supplied from the provider or operator.
Usually there is one password which applies to all call barring
options. For details contact your provider. With AT+CPWD or
AT^SPWD the default password can be changed individually. After 3 failed attempts to enter the correct password, the client is
required to contact the provider.
When you attempt to set a <fac> 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”, “Operation not allowed”, “Operation not supported” etc.). To make sure check the call barring status with
<mode>=2.

4.21.1 Examples: Enabling / disabling PIN 1 authentication
Example 1
TC35i_ATC_V00.01
To lock or unlock the SIM card: The "SC" parameter enables or disables the
SIM PIN authentication (PIN 1) when you power up the GSM engine:
AT+CLCK="SC",1,”9999”
Activates SIM card lock.
OK
As a result, SIM PIN 1 must be entered to enable ME to register to the GSM network.
AT+CLCK="SC",0,”9999”
Unlocks SIM card.
OK
When powered up, ME registers to the GSM
network without requesting SIM PIN1.
Note: Depending on the services offered by the
provider, this feature is not supported by all
SIM card types. If so, the command returns

4.28 AT+CMUX Enter multiplex mode
Multiplex mode according to the ETSI TS 101 669 and GSM 07.10 enables one physical serial
asynchronous interface to be partitioned into three virtual channels. This allows you to take advantage of up to 3 simultaneous sessions running on the serial interface. For example, you can send or
receive data or make a call on the first channel, while the other two channels are free to control the
module with AT commands.
The 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 [3] which provides a detailed description of the multiplex architecture and step-by-step instructions of how to install and configure the multiplex mode. The WinMUX2k driver and its source
files can be supplied on request. Please contact your local distributor to obtain the latest installation
software and user's guide.

1. 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.
2. 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 the AT command mode.

3. There are various options to switch from data mode to command mode:
a) Escape sequence +++ (see notes below).
b) Circuit 108/2 (DTR) changes from ON to OFF, reaction depends on
command at&d (caution if AT&D0: TA ignores status on DTR).
c) The message Modem Status Command (MSC) for control channel is
defined by the multiplexer protocol GSM07.10. MSC conveys V.24
signals. Bit 3 of Control Signal Octet is DTR, reaction depends on
command at&d (caution if AT&D0: TA ignores status on DTR).
4. The parameter maximum frame size (N1) of AT+CMUX in GSM07.07 is
fixed to 97 and cannot be changed. All other parameters are not available.
5. Multiplex mode can be terminated by AT^SMSO (,AT^SMSO Switch off
mobile station" pg. 196). It has to be reestablished after power-on.
4.28.1 Restricted use of AT commands in 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 [3].

The applicability of the +++ escape sequence depends on the customer’s external application
based on the Mulitplexer Protocol. The WinMux2k driver uses the +++ escape sequence as described in Chapter 2.2. Recommendations for implementing an appropriate modem status command (MSC) are provided in [3], Chapter “Escape Sequence”.

4.30 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. If the operator is found, ME immediately registers to this network. 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.
Test command
AT+COPS=?
TA returns a list of quadruplets, each representing an operator present in the
network. The list of operators is presented in the following order: Home network, networks referenced in SIM, and other networks. Two consecutive

The AT+CPBW command can be used only after the phone book data from the
SIM have been read successfully for the first time. Reading starts after successful SIM authentication has been performed, and may take several seconds
depending on the SIM used. While the read process is in progress, an attempt
to use any of the phone book commands will result in “+CME Error: 14” (SIM
busy).
If <text> contains characters which are coded differently in ASCII and GSM
(e.g. Ä, Ö, Ü), these characters have to be entered via escape sequences as
described in Chapter 1.5.
Notes regarding <nlength> of <number>
Normally, <nlength> is 20. This means <number> may consist of 20 characters
including digits and dial string modifiers, such as “*”,”#” or “+”.
If <number> contains other types of dial string modifiers, for example “-“, the
number cannot be stored in BCD format and, thus, requires double memory. In
order to fit into a standard location, the number needs to be reduced to
<nlength>/2. Therefore, it must be limited to 10 characters comprising digits
and the desired dial string modifier(s).
A limited number of locations with extended memory is available per phone
book. These locations allow storing numbers with twice the standard length,
which is 2*<nlength> digits for normal numbers or <nlength> digits for numbers
that cannot be stored in BCD format. If all extended locations of the selected
phone book are used up, then any attempt to write a number which requires extended memory will be denied with CME ERROR 260: INVALID DIAL STRING.

Write command
Response
AT+CPIN=<pin>
[,<new pin>]
The write command lets the ME store the entered password. This may be for
example the SIM PIN1 to register to the GSM network, or the SIM PUK1 to replace a disabled PIN with a new one, or the PH-SIM PIN if the client has taken
precautions for preventing damage in the event of loss or theft etc. See above
for the list of passwords.
OK
If error is related to ME functionality:
+CME ERROR: <err>
If no PIN request is pending (for example if PIN authentication has been done
and the same PIN is entered again) ME responds +CME ERROR: operation not
allowed. No action is required from your part.
Parameter
<pin>
password (string type), for example SIM PIN or, if requested, one
of the unblocking keys, such as SIM-PUK or PH-SIM PUK.
<new pin>
If the ME is waiting for an unblocking key, use <pin> to enter the
unblocking key, followed by <newpin> to specify the password.
See Chapter 4.35.1 for more information about when you may
need to enter an unblocking key.
Reference
Note
GSM 07.07
· 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.
The response in these cases will be “+CME Error: 14” (SIM busy).
· Successful PIN authentication only confirms that the entered PIN was recognized and correct. The output of the result code OK does not necessarily
imply that the mobile is registered to the desired network.

Typical example: PIN was entered and accepted with OK, but the ME fails
to register to the network. This may be due to missing network coverage,
denied network access with currently used SIM card, no valid roaming
agreement between home network and currently available operators etc.
TC35i offers various options to verify the present status of network registration: For example, the AT+COPS? (Chapter 4.30) command indicates the
currently used network. With AT+CREG (Chapter 4.41) 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 Chapter 7.38.
See also Chapter 8.2 “Summary of PIN requiring AT Commands“.
See Chapters 4.38 and 7.42 for information on passwords.

4.35.1 What to do if PIN or password authentication fails?
PIN1 / PUK1:
After three failures to enter PIN1, the SIM card is blocked (except for emergency
calls). To unblock the SIM card, the client needs to enter 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 three options:
§ You can enter AT+CPIN=PUK1,new PIN1.
§ You can enter AT+CPWD=”SC”,PUK1,new PIN1.
§ You can use the ATD command followed by the GSM code
**05*PUK*newPIN*newPIN#;.
PIN2 / PUK2:
PIN2 allows access to the features listed in Chapter 4.36. 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 three options:
§ You can enter AT+CPIN2=PUK2,new PIN2.
§ You can enter AT+CPWD=”P2”,PUK2,new PIN2.
§ You can use the ATD command followed by the GSM code
**052*PUK*newPIN*newPIN#;.
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 of the TC35i module. When needed, contact Siemens
AG and request the Master Phone Code of the specific module.
There are three ways to enter the Master Phone Code:
§ You can enter AT+CPIN=Master Phone Code,new password.
§ You can enter AT+CPWD=”PS”,Master Phone Code,new password.
§ You can use the ATD command followed by the GSM
**052*PUK*newPIN*newPIN#;.
code
Usually, the Master Phone Code will be supplied by mail or e-mail. The received number may be enclosed in the *# codes typically used for the ATD option. If you use the
AT+CPIN or AT+CPWD command, 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 9).
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.

<currency>
string type; three-character currency code (e.g. “GBP”, “EUR”);
character set as specified with AT+CSCS. 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>
string type; 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.
Due to storage in mantisse (range 0-4095) and exponent (-7
to 7) it is possible that rounding errors occur.
Note:
<passwd>
Reference
string type; 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

to subscribe them, though a limited number of call barring types
may be included in the basic tariff package. Call barring is protected by a password supplied from the provider or operator.
Usually there is one password which applies to all call barring
options. For details contact your provider. With AT+CPWD or
AT^SPWD the default password can be changed individually.
<oldpwd>
Password specified for the facility.
Can be ignored if no old password was allocated to the facility.
Take into account that a password may have already been set

<newpwd>
New password. Mandatory, if <oldpwd> was an unblocking key
(such as PUK1, PUK2, Master Phone Code).
Note:
The length of the old and new password depends on the associated
<fac>. The maximum length can be queried using the Test command
AT+CPWD=?.
If <fac> = “SC”: SIM PIN comprising 4 – 8 digits. After 3 failed attempts
the 8-digit SIM PUK is required.

4.43 AT+CRSM Restricted SIM access
Test command
Response
AT+CRSM=?
OK
Write command
By using this command the TE has access to the SIM database. SIM access is
restricted to the commands which are listed below.
As response to the command the ME sends the current SIM information parameters and response data. ME error result code +CME ERROR may be returned if the command cannot be passed to the SIM, e.g. if the SIM is not inserted. However, errors related to SIM data are reported in <sw1> and <sw2>
parameters as defined in GSM 11.11.
This command requires PIN authentication. However, using <command> READ
BINARY and <command> READ RECORD is possible before PIN authentication and if the SIM is blocked (after three failed PIN authentication attempts) to

character sets.
OK
Parameters
<chset>:
"GSM" 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, $(AT R97)$

4.45 AT+CSNS Single Numbering Scheme
The AT+CSNS command enables the ME to accept incoming calls when no bearer capability information is provided with the call, e.g. single numbering scheme calls or calls originitating from analog
devices.
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.
Please note that you can use the command if PIN authentication has been done during current session. The setting will be automatically saved when you power down the GSM engine with AT^SMSO.

· After invoking the commands CMGW, CMGS, CMGC wait for the

prompt a timer will be started to observe the input.
· To send the message simply enter <CTRL-Z>. See Execute command for possible responses.
· Sending can be aborted by entering <ESC>. Of course, the message will not be sent, though the operation is acknowledged with
OK.
· When sending e-mails via SMS check that, depending on the provider, the @ symbol will be recognized and correctly interpreted. If
not, make sure what character to use instead. A widely used alternative is typing “*”.
· At baudrates lower than 19200 it is recommended to use the line
termination character only (refer to +ATS3, default <CR>, Chapter
2.21) before entering the text/pdu. Use of the line termination
character followed by the response formating character (refer to
+ATS4, default <LF>, Chapter 2.22) can cause problems.
· 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 SMS 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. See also Chapter 8.5 which provides the supported alphabet tables.
· 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

General remarks:
· The parameters <ra> and <tora> will only be displayed if AT^SSCONF=1 has
been set before. See Chapter 7.44 for details on AT^SSCONF.
· To allow SMS overflow presentation during data transfers via Break, use
AT+CNMI=3,1 (see Chapter 7.20, AT^SMGO).
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. Refer to Chapter 7.45
for details.
· 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 TP-DCS and normal rules for exceeded memory capacity shall apply.
This approach is compliant with GSM 03.38.
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 +CNMI parameters
will be set to zero on all channels.

General remarks
· The parameters <mem1>, <mem2> and <mem3> are saved in the non-volatile
memory.
· The Mobile Equipment storage "ME" offers space for 25 short messages.
· “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: For instructions of how to change the order of the
“MT” storage refer to Chapter 7.47.
· 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.

TC35i AT Command Set
PRELIMINARY
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 in Chapter 7.20) may be
presented without prior indication of ^SMGO: 1. For more information regarding
SIM and ME specific message classes refer to <dcs> and the following specifications: GSM 03.38 and 3GPP TS 23.038.
Handling of <mem3> storage:
· 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.
· In Multiplex mode, the parameter <mem3> will be the same on all instances,
but the settings of <mem1> and <mem2> may vary on each channel.
· 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 client’s concern to have received short messages stored
only to the SIM card, inconsistent settings should be generally avoided. This
can be achieved simply by using the same parameter for all <memx>.

6 AT Commands for SIM Application Toolkit (GSM 11.14)
SIM Application Toolkit (SAT) is a technology that lets the SIM card execute a great variety of additional applications. Conventionally, SIM cards are intended to store user specific data, such as phone
books, secure user identification codes and messages, but they can also hold a lot of value-added
mobile applications.
The SAT functionality integrated in TC35i and MC35T allows to execute network specific applications
implemented on the SIM card. Typical examples are online banking and information services.
The commands exchanged between SAT and the SIM application fall into two categories:
· Proactive commands – sent from the SIM application to the module’s SAT, e.g. DISPLAY TEXT.
· Envelope commands – sent from the module's SAT to the SIM application, e.g. MENU SELECTION.
The SAT implementation supports SAT class 3, GSM 11.14 Release 98, support of letter class “c”.
GSM 11.14 describes Proactive and Envelope Commands in detail.
Note:
To give you an idea, this chapter contains a brief overview of the AT commands and responses related to the SIM Application Toolkit (SAT) implementation. The full set of SAT specific AT commands and a detailed descripton of the SAT functions is provided in [2].

^SSTN Remote-SAT Notification
Proactive
Commands
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. selected menu item.

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),

· 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 are not available under certain conditions and
therefore, are displayed as “-“ (for conditions see also +CREG, pg 129). 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’.
· The cell information can be issued in the form of unsolicited result codes (related to <period>), or it can be queried directly using the Execute command
AT^MONI. In the first case, the ME activates its RING line (Logic “1”) for one
second to send the URC to the connected application. In the second case, the
RING line does not change.
· 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.

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

AT^SBC Battery charge and charger control
Responses returned by the AT^SBC command vary with the operating mode of the ME:
Normal mode:
Normal mode + charging:
Charge-only mode:
Alarm 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>).
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. Battery capacity
is not available.
Allows charging while ME is detached from GSM network. When
started, the mode is indicated by the URC "^SYSSTART CHARGEONLY 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 Table 10). There are several ways to activate the
Charge-only mode:
a) from Power Down mode: Connect charger while ME was powered
down with AT^SMSO
b) from Normal mode: Connect charger, then enter AT^SMSO.
No charging functionality, i.e. charging does not start even though
the charger is connected. Battery parameters are not available.
Charging begins once the charger is connected to the POWER pin of the external charging circuit.

<bcl>
Battery charge level
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) no
battery capacity value is available. Consequently, parameter
<bcl>=0. To query the battery capacity disconnect the charger.
<mpc>
Average power consumption
<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, GPRS/DATA)
and the power level.
If <current> was not yet specified and no battery pack NTC is
detected <mpc> returns only the module's present 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 to <mpc>. 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 [1], the
battery cannot be detected by the ME.
Write command
AT^SBC=
<current>
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. This affects the charging control and disables the presentation of unsolicited result codes. Therefore, the parameter should be set every time when
needed after rebooting the ME.

Unsolicited result
codes
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.
Warning and shutdown thresholds depend on a variety of factors. An important
issue is for example whether or not an NTC is connected to the BATT_TEMP
terminal of the application interface. For further details regarding automatic shutdown and voltage ratings please refer to [1].
^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.
^SBC: Overvoltage warning
This URC is only intended for applications which are not battery powered (= no
NTC connected to BATT_TEMP). It is an alarm indicator displayed when the supply voltage approaches its maximum level. The URC appears only once.
^SBC: Overvoltage shutdown
This URC can be presented regardless of the presence of an NTC at
BATT_TEMP. The message will be reported when the voltage exceeds the
maximum level. If charging is not properly terminated, for example due to an error
caused by a bad battery, the message will also be presented to avoid overcharging. In either case, the URC appears only once before the module switches off.
The automatic shutdown procedure caused by undervoltage or overvoltage is
equivalent to the power-down initiated with the AT^SMSO command, i.e. TC35i
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.
Reference
Note
Siemens
· If Multiplex mode is active, any virtual channel can be used to enter the write

Important:
· Please refer to [1] for specifications on critical temperature ranges.
· 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
module 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 TC35i
switches off immediately.

<fac> Phone security locks:
“SC” SIM (lock SIM cards). SIM requests password upon ME powerup and when this lock command is issued.
<password>: SIM PIN1. The password can be modified with
AT+CPWD or AT^SPWD (see Chapters 4.38 and 7.42).
“PS” Phone locked to SIM card. ME requests password when other
than current SIM card is inserted.
<password>: User defined password. It is needed before the first
use of <fac>”PS and, therefore, must first be specified with
AT+CPWD or AT^SPWD.
“FD” SIM fixed dialing memory: If the mobile is locked to "FD", only
the phone numbers stored to the "FD" memory can be dialed
(depending on the SIM card, usually up to 7 numbers).
<password>: SIM PIN2 (or equivalent authorisation via
AT+CPIN2, see Chapter 4.36.)
If a lock on the SIM fixed dialing memory is active, call related
Supplementary Services such as call barring, call waiting or call
forwarding cannot be accessed via AT command. The response
will be “ +CME ERROR: call barred”. In this case, access to call
related Supplementary Services is possible only if the corresponding public MMI *# code is stored in the fixed dialing number phone book, or by deactivation of the SIM fixed dialing facility
lock)
Note:
TC35i_ATC_V00.01
"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 TC35i module.
Once the Master Phone Code has been acctepted, the mobile is
operational, and the "PS" lock is no longer active. See Chapter
4.35.1 and examples below for further details.

<password>: Factory set password. See note below.
“PF” lock Phone to the very First SIM card
“PN” Network Personalisation
“PU” Network subset Personalisation
“PP” Service Provider Personalisation
“PC” Corporate Personalisation
Note:
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 end user 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 of the TC35i
modules 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.
See Chapter 4.35 and 4.35.1 for further instructions.
Supplementary Service: Call barring:
<password>: Network dependent password. See note below.
“AO” BAOC (Bar All Outgoing Calls)
“OI” BOIC (Bar Outgoing International Calls)
“OX” BOIC-exHC (Bar Outgoing International Calls except to Home
Country)
“AI” BAIC (Bar All Incoming Calls)
“IR” BIC-Roam (Bar Incoming Calls when Roaming outside the home
country)
“AB” All Barring services (applicable only for <mode>=0)
“AG” All outGoing barring services (applicable only for <mode>=0)
“AC” All inComing barring services (applicable only for <mode>=0)
Note:
The availability of the Supplementary Services varies with the
network. To benefit from call barring services the client will need
to subscribe them, though a limited number of call barring types
may be included in the basic tariff package. Call barring is protected by a password supplied from the provider or operator.
Usually there is one password which applies to all call barring
options. For details contact your provider. With AT+CPWD or
AT^SPWD the default password can be changed individually. After 3 failed attempts to enter the correct password, the client is
required to contact the provider.
When you attempt to set a <fac> 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”, “Operation not allowed”, “Operation not supported” etc.). To make sure check the call barring status with
<mode>=2.

For example, the default setting 7 represents the sum of the
integers 1, 2 and 4 (call barring for voice, data and fax). The
value 255 covers all classes. If the <class> parameter is
omitted, the default value 7 is used.
See examples in 4.21.3 for correct handling of class numbers.
<class> 2 (data) comprises all those <class> values between 16 and
128, that are supported both by the network and the MS. This means,
a setting made for <class> 2 applies to all remaining data classes (if
supported). In addition, you can assign a different setting to a specific
class. For example, you can activate call barring for all data classes,
but deactivate it for a specific data class.

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

the Execute command AT^SMOND. In the first case, the ME activates its
RING line (Logic “1”) for one second to send the URC to the connected application. In the second case, the RING line does not change.
· 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.

Siemens
· The read and write commands refer to the active audio mode.
· The write command works only in audio modes 2 to 6.
· <outCalibrate> specifies the amount of volume of each <outStep>. The
range of <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.
· The value of <outStep> is stored non-volatile when the ME is powered
down with AT^SMSO or reset with AT+CFUN=1,1. 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.
· 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!
· <outStep> can also be selected with AT^SNFV (see Chapter 7.32) and
AT+CLVL (see Chapter 4.24).

AT^SNFS?
^SNFS: <audMode> OK
Parameter

Write command
AT^SNFS=
<audMode>
The write command serves to set the audio mode required for the connected
equipment. For use after restart of TC35i, 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 TC35i 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 interface can be assigned a specific audio mode. To 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^SAIC. See Chapters 7.5 for AT^SAIC and 7.33 for
AT^SNFW.
Response
OK
If error is related to ME functionality:
+ CME ERROR: <error>
Parameters
<audMode> 1
Audio mode 1: Standard mode optimized for the default handset, that can be connected to the analog interface 1 (see [1]
and for information on this handset.) To adjust the volume use
the knob of the default handset. In audio mode 4 and 5, 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.
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.
In modes 2 – 6, audio parameters can be adjusted with AT commands.

Note
Siemens
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, i.e. when selecting another audio mode 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 changes to another audio mode then the microphone remains muted until explicitly changed. Exception: In audio mode 1 <outStep>=4 is
fix.

OK
Parameter
<outStep>
Volume steps 0 to 4. In each audio mode, factory default is 4.
The actual volume of each step is defined by the parameter <outCalibrate[n]> which can be set with AT^SNFO.
Reference
Note
Siemens
· The read and write commands refer to the active audio mode.
· The write command works only in audio modes 2 to 6.
· Any change to <outStep> takes effect in audio modes 2 to 6. That is, when you
change <outStep> and then select another mode with AT^SNFS, the same step
will be applied. Nevertheless, the actual volume can be quite different, depending on the values of <outCalibrate[n]> set in each mode.
The only exception is audio mode 1 which is fixed to <outStep>=4.
· <outStep> is stored non-volatile when the ME is powered down with AT^SMSO
or reset with AT+CFUN=1,1.
· <outStep> can also be changed with AT^SNFO (Chapter 7.29) and AT+CLVL
(Chapter 4.24).

Before first using ringing tones:
We have chosen to let you decide your own preferences when you start using
ringing tones. Therefore, factory setting is AT^SRTC: 3,0,3,0,0 (ringing tones
are muted). To activate ringing tones for the very first time, first enter the
Write command and simply change the volume.
<type>=0:
AT^SRTC=0 can be entered to quickly mute the ringing tone or melody currently played to indicate an <event>. No settings will be changed or saved.
<type>=0 immediately stops the audible ringing tone, but does not terminate
the URC (for example RING).
Execute Command
AT^SRTC
The Execute command is intended for testing. It starts to play a melody from
the audio output currently selected with the AT^SNFS command.
Response
OK
To stop the test 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
ringing tone, and to view the status of playback (on / off).
The test ringing signal cannot be activated when an MTC is ringing (ERROR).
If an MTC arrives during test playback, test ringing stops and “normal“ ringing
is activated (RING).
Selecting <vol>=0 during the test, immediately stops playback. After this, ringing tones will be muted until you change <vol> using the Write command.

The ^SSYNC command serves to configure the SYNC pin of the TC35i application interface. Please

Note
0 Enables the SYNC pin to indicate growing power consumption during a transmit burst. You can make use of the signal
generated by the SYNC pin, if power consumption is your
concern. To do so, ensure that your application is capable
of processing the signal. Your platform design must be such
that the incoming signal causes other components to draw
less current. In short, this allows your application to accommodate current drain and thus, supply sufficient current to
the GSM engine if required.
1 Enables the SYNC pin to control a status LED installed in
your application according to the specifications provided in
[1].
The coding of the LED is described in Table 11.
The SYNC pin mode is stored to the non-volatile Flash memory, and thus
retained after Power Down.

Enable/Disable automatic dialling from phone book on DTR activation
(ON/OFF transition).
If automatic dialling is enabled and the DTR signal line switches from OFF to
ON, 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.
When a call setup starts all other active or held calls are dismissed.
Repeated DTR OFF/ON transitions caused by a DTR activation event while
call setup is in progress are ignored. Also, 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,<pin>. 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 Facility lock”, pg. 92.
Response

8.1
Summary of 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 AT+CMEE command (see
Chapter 4.25).

Note:
If you attempt to use SMS related AT commands before inserting a SIM card or entering the SIM PIN,
the resulting errors will be delivered in the form of CME errors instead of CMS errors.
This is a normal behavior since the GSM 07.05 based CMS errors are mapped to GSM 07.07 based
CME errors if SIM PIN authentication has not been done.

8.1.3 Summary of Unsolicited Result Codes (URC)
A URC is a report message sent from the ME to the TE. An unsolicited result code can either be delivered automatically when an event occurs or as a result of a query the ME received before. However, a
URC is not issued as a direct response to an executed AT command.
Typical URCs may be information about incoming calls, received SMS, changing temperature, status
of the battery etc. A summary of URCs is listed in Table 12 and Table 13.
When sending a URC the ME activates its Ring Line (Logic "1"), i.e. the line goes active low for 1 second.
If an event that delivers a URC coincides with the execution of an AT command, the URC will be output after command execution has completed.
For each of these messages, you can configure the ME whether or not to send an unsolicited result
code. Remember that the presentation mode of URCs will be reset to the default values
· when you power down the GSM engine, e.g. with AT^SMSO or when disconnecting power supply,
· when you reset the engine with AT+CFUN=1,1
· when you restore the factory settings with AT&F.
To take advantage of the messages, you need to activate the desired URC every time you reboot the
GSM engine or have the parameters included in the user profile saved with AT&W. If you do so, take
into account that the presentation mode of some URCs cannot be saved to the user profile, for example ^SBC, ^SCTM, +CSSI and +CSSU. A list of parameters saved with AT&W is provided in Chapter
2.38.
The URCs SYSSTART and SYSSTART ALARM MODE are not user definable. This is also true for the

8.4.1 Additional notes on ^SCCFC, +CCWA, ^SCLCK
The following is a brief summary of differences between the *# codes for Call Forwarding, Call Waiting
and Call Barring and their equivalent AT commands:
Differences regarding the syntax:
The number of parameters displayed in the ^SCCFC and ^SCLCK output strings differs from the
equivalent +CCFC and +CLCK output strings: In contrast to the +CCFC string, ^SCCFC also includes
the <reason>. Likewise, the ^SCLCK string includes additionally <fac>.
Response to atd*#21#; (query status of Call Forwarding Unconditional):
^SCCFC: <reason>, <status>, <class1>[, <number>, <type> [, <time>]]
Response to to at+ccfc=0,2 (query status of Call Forwarding Unconditional):
+CCFC: <status>, <class1>[, <number>, <type> [, <time>]]
Differences regarding default basic services / classes:
In the query mode, if no basic service is given, the *# codes use default <class> 15 (= voice, data, fax,
SMS). In contrast to this, the AT commands AT+CCFC, AT+CCWA, AT+CLCK, AT+SCLCK use default <class> 7 (=voice, data, fax).

This code is an escape to the following extension of the 7 bit default alphabet table.
This code is not a printable character and therefore not defined for the UCS2 alphabet. It shall be treated as
the accompanying control character.

1) This code value is reserved for the extension to another extension table. On receipt of this
code, a receiving entity shall display a space until another extension table is defined.
2) This code represents the EURO currency symbol. The code value is the one used for the
character ‘e’. Therefore a receiving entity which is incapable of displaying the EURO currency symbol will display the character ‘e’ instead.
3) This code is defined as a Page Break character and may be used for example in compressed CBS messages. Any mobile which does not understand the 7 bit default alphabet
table extension mechanism will treat this character as Line Feed.
