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).
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 defi-
nitions 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).

Using Parameters
•
•
•
•
Optional parameters are enclosed in square brackets. If optional parameters are omitted, the current settings
are used until you change them.
Optional parameters or subparameters can be omitted unless they are followed by other parameters. If you
want to omit a parameter in the middle of a string it must be replaced by a comma. See also example 1.
A parameter value enclosed in square brackets represents the value that will be used if an optional parameter
is omitted. See also example 2.
When the parameter is a character string, e.g. <text>or <number>, the string must be enclosed in quotation
marks, e.g. "Charlie Brown" or "+49030xxxx". Symbols in quotation marks will be recognized as strings.
•
•
•
All spaces will be ignored when using strings without quotaton marks.
It is possible to omit the leading zeros of strings which represent numbers.
If an optional parameter of a V.250 command is omitted, its value is assumed to be 0.
Example 1: Omitting parameters in the middle of a string
AT+CCUG?
+CCUG: 1,10,1
OK

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.

1.5 Supported character sets
s
1.5
Supported character sets
The ME supports two character sets: GSM 03.38 (7 bit, also referred to as GSM alphabet or SMS alphabet) and
UCS2 (16 bit, refer to ISO/IEC 10646). See AT+CSCSfor information about selecting the character set. Character
tables can be found below.
Explanation of terms
•
International Reference Alphabet (IRA)
IRA means that one byte is displayed as two characters in hexadecimal format. For example, the byte 0x36
(decimal 54) is displayed as "36" (two characters). IRA is used here for input 8-bit or 16-bit data via terminal
devices using text mode. This means only characters 'A'..F','a'..'f' and '0'..'9' are valid.
•
Escape sequences
The escape sequence used within a text coded in the GSM default alphabet (0x1B) must be correctly inter-
preted by the TE, both for character input and output. To the module, an escape sequence appears like any
other byte received or sent.
•
•
Terminal Adapter (TA)
TA is used equivalent to Mobile Equipment (ME) which stands for the GSM module described here. It uses
GSM default alphabet as its character set.
Terminal Equipment (TE)
TE is the device connected to the TA via serial interface. In most cases TE is an ANSI/ASCII terminal that
does not fully support the GSM default alphabet, for example MS Hyperterminal.
•
•
TE Character Set
Data Coding Scheme (dcs)
DCS is part of a short message and is saved on the SIM. When writing a short message to the SIM in text
The behavior when encountering characters, that are not valid characters of the supported alphabets, is unde-
fined.
Due to the constraints described below it is recommended to prefer the USC2 alphabet in any external applica-
tion.
If the GSM alphabet is selected all characters sent over the serial line (between TE and TA) are in the range from
0 to 127 (7 Bit range). CAUTION: ASCII alphabet (TE) is not GSM alphabet (TA/ME) !
Several problems resulting from the use of GSM alphabet with ASCII terminal equipment:
•
"@" character with GSM alphabet value 0 is not printable by an ASCII terminal program (e.g. Microsoft©
Hyperterminal®).
•
"@" character with GSM alphabet value 0 will terminate any C string! This is because the 0 is defined as C
string end tag. Therefore, the GSM Null character may cause problems on application level when using a 'C'-
function as "strlen()". This can be avoided if it is represented by an escape sequence as shown in the table
below.
By the way, this may be the reason why even network providers often replace "@"with "@=*" in their SIM
application.
•
•
Other characters of the GSM alphabet are misinterpreted by an ASCII terminal program. For example, GSM
"ö" (as in "Börse") is assumed to be "|" in ASCII, thus resulting in "B|rse". This is because both alphabets mean
different characters with values hex. 7C or 00 and so on.
In addition, decimal 17 and 19 which are used as XON/XOFF control characters when software flow control
is activated, are interpreted as normal characters in the GSM alphabet.
When you write characters differently coded in ASCII and GSM (e.g. Ä, Ö, Ü), you need to enter escape
sequences. Such a character is translated into the corresponding GSM character value and, when output later,
the GSM character value can be presented. Any ASCII terminal then will show wrong responses.

CAUTION: Often, the editors of terminal programs do not recognize escape sequences. In this case, an escape
sequence will be handled as normal characters. The most common workaround to this problem is to write a script
which includes a decimal code instead of an escape sequence. This way you can write, for example, short mes-
sages which may contain differently coded characters.

2) This code represents the EURO currency symbol. The code value is the one used for the character 'e'. Therefore a receiv-
ing 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

UCS2 and GSM data coding and conversion for SMS text mode
This section provides basic information on how to handle input and output character conversion for SMS text
mode and Remote-SAT if internal (TA) and external (TE) character representation differ, i.e. if the Data Coding
Scheme and the TE character use different coding.
1.5.2.1 Implementing output of SIM data to Terminal (direction TA to TE)

Case 4

Case 5
8 bit to IRA (1:4)
Case 6
UCS2 to IRA (2:4)
Note: The ratio of SIM bytes to output bytes is given in parentheses.
Case 1
Every GSM character is sent to TE as it is (8-bit value with highest bit set to zero).
Example: 47'H, 53'H, 4D'H → 47'H, 53'H, 4D'H, displayed as "GSM"
Case 2
Every data byte will is sent to TE as 2 IRA characters each representing a halfbyte.
Example: B8'H (184 decimal) → 42'H, 38'H, displayed as "B8"
Case 3
Every 16-bit UCS2 value is sent to TE as 4 IRA characters.
Example: C4xA7'H (50343 decimal) → 43'H, 34'H, 41'H, 37'H, displayed as "C4A7"
Problem: An odd number of bytes leads to an error because there are always two bytes needed for each USC2
character
Case 4
Every GSM character is sent to TE as 4 IRA characters to show UCS2 in text mode.
Example: 41'H ("A") → 30'H, 30'H, 34'H, 31'H, displayed as "0041"
Case 5
Every data byte is sent to TE as IRA representation of UCS2 (similar to case 4).
Example: B2'H → 30'H, 30'H, 42'H, 32'H, displayed as "00B2"
Case 6
Every 16-bit value is sent to TE as IRA representation of it. It is assumed that number of bytes is even.
Example: C3x46'H → 43'H, 33'H, 34'H, 36'H, displayed as "C346"

Note: The ratio between the number of input characters and bytes stored on the SIM is given in parentheses.
Case 1
Every character is sent from TE to TA as GSM character (or ASCII with Hyperterminal).
Character value must be in range from 0 to 127 because of 7-bit GSM alphabet.
To reach maximum SMS text length of 160 characters in 140 bytes space characters will be compressed on SIM.
Example: "ABCDEFGH" typed is sent and stored uncompressed as → 4142434445464748'H (stored com-
pressed as 41E19058341E91'H)
Case 2
Every data byte is sent to TA as 2 IRA characters.
Maximum text length is 280 IRA characters which will be converted into 140 bytes SMS binary user data
Example: "C8" typed is sent as 43'H, 38'H → stored as C8'H
Case 3
Every 16-bit value is sent to TA as 4 IRA characters.
Maximum text length is 280 IRA characters which will be converted into 70 UCS2 characters (16-bit each)
Number of IRA characters must be a multiple of four because always 4 half bytes are needed for a 16-bit value
Example: "D2C8" typed is sent as 44'H, 32'H, 43'H, 38'H → stored as D2C8'H
Case 4
Every GSM character is sent to TA as 4 IRA characters representing one UCS2 character.
Example: To store text "ABC" using UCS2 character set you have to type "004100420043".
This is sent as 30'H,30'H,34'H,31'H, 30'H,30'H,34'H,32'H, 30'H,30'H,34'H,33'H → detected as IRA representa-
tion of 3 UCS2 characters, converted to GSM character set and stored as 41'H, 42'H, 43'H.
Maximum input is 640 IRA characters repesenting 160 UCS2 characters when compression is active. These are
converted to 160 GSM 7-bit characters.
Without compression only 140 GSM characters can be stored which are put in as 560 IRA characters.
Values of UCS2 characters must be smaller than 80'H (128 decimal) to be valid GSM characters.
Number of IRA characters must be a multiple of four. Problems:
• "41" → Error, there are four IRA characters (two bytes) needed
• "0000" → Error, not an UCS2 character
• "4142" → Error, value of UCS2 character > 7F'H
• "008B" → Error, value of UCS2 character > 7F'H
This affects the maximum input length of a string)
Case 5
Every UCS2 character is sent as 4 IRA characters and is converted into two 8-bit values. This means that the
first two characters have to be '00'.
Example: UCS2 character 009F'H typed as "009F" is sent as 30'H,30'H,39'H,46'H → converted into 8-bit value
9F'H.
Maximum number of UCS2 characters is 140 which are represented by 560 IRA characters. Number of IRA char-
acters must be a multiple of four.
Case 6
Every UCS2 character is sent as 4 IRA characters each and is converted into a 16-bit value again.
Example: UCS2 character 9F3A'H typed as "9F3A" is sent as 39'H,46'H,33'H,41'H → converted into 9F3A'H.
Maximum number of UCS2 characters is 70 which are represented by 280 IRA characters. Number of IRA char-
acters must be a multiple of four.
Invalid UCS2 values must be prevented.

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.
1.6.1
Software Flow Control (XON/OFF Handshake)
Software flow control sends different characters to stop (XOFF, decimal 19) and resume (XON, decimal 17) data
flow. The only advantage of software flow control is that three wires would be sufficient on the serial interface.
1.6.2
Hardware Flow Control (RTS/CTS Handshake)
Hardware flow control sets or resets the RTS/CTS wires. This approach is faster and more reliable, and there-
fore, the better choice. When the High Watermark is reached, CTS is set inactive until the transfer from the buffer
has completed. When the Low Watermark is passed, CTS goes active again.
To achieve smooth data flow, ensure that the RTS/CTS lines are present on your application platform. The appli-
cation 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\Qhas no read command. To verify the current setting of AT\Q, simply check the settings of the active profile
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.

1.7 Unsolicited Result Code Presentation
s
1.7
Unsolicited Result Code Presentation
URC stands for Unsolicited Result Code and is a report message issued by the ME without being requested by
the TE, i.e. a URC is issued automatically when a certain event occurs. Hence, a URC is not issued as part of
the response related to an executed AT command.
Typical events leading to URCs are incoming calls ("RING"), waiting calls, received short messages, changes in
temperature, network registration etc.
To announce a pending URC transmission the ME will do the following:
•
The ME activates its RING line (logic "1") for 1 second, i.e. the RING line changes to the physical "Low" level.
This allows the TE to stay in power saving mode until an ME related event requests service.
If several URCs occur coincidently or in quick succession each URC triggers the RING line independently,
although the line will not be deactivated between each URC. As a result, the RING line may stay low for more
than 1 second.
If an incoming call is answered within less than 1 second (with ATAor if autoanswering is set to ATS0=1) than
the RING line will be deactivated earlier.
•
If the AT command interface is busy a "BREAK" will be sent immediately but the URC will not be issued until
the line is free. This may happen if the URC is pending in the following cases:
-
During the processing of an AT command (i.e. the time after the TE echoes back the first character "A" of
an AT command just sent by itself until the ME responds with "OK" or "ERROR").
-
During a data call.
Please note that AT command settings may be necessary to enable in-band signaling, e.g. refer to AT+CMER
It is strongly recommended to use the multiplex mode to map logical communication channels onto the serial line
of the TC63, for details refer to [5] and AT command AT+CMUX. Doing so it is possible to use one channel to still
process URCs while having a data call active on another.
For most of these messages, the ME needs to be configured whether or not to send a URC. Depending on the
AT command, the URC presentation mode can be saved to the user defined profile (see AT&W), or needs to be
If autobauding is enabled (as factory default mode or set with AT+IPR=0), URCs generated after restart will be
output with 57600 bps until the ME has detected the current bit rate. The URCs "^SYSSTART", "^SYSSTART
<text>", however, are not presented at all. For details please refer to Section 4.9.1, Autobauding. To avoid prob-
lems we recommend to configure a fixed bit rate rather than using autobauding.
1.7.1
Communication between Customer Application and TC63
Leaving hardware flow control unconsidered the Customer Application (TE) is coupled with the TC63 (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 TC63 starts sending an URC. This will probably lead to the TE's misinterpretation of the URC
being part of the AT command's response.
To avoid this conflict the following measures must be taken:
•
If an AT command is finished (with "OK" or "ERROR") the TE shall always wait at least 100 milliseconds
before sending the next one.
This gives the TC63 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.
•
received from the TE.
Hence, when the TE receives the echo of the first character "A" of the AT command just sent by itself it has
control both over the receive and the transmit paths.

The command result codes "+CME ERROR: <err>" and "+CMS ERROR: <err>" indicate errors related to mobile

A result error code terminates the execution of the command and prevents the execution of all remaining com-
mands that may follow on the same command line. If so, neither "ERROR" nor "OK" result codes are returned
for these commands. A 30 seconds timeout will deliver "ERROR" when the input of a command is not complete.
Using the wrong command syntax may result in errors: For example, using the execute command syntax
although the command has no execute format, causes "ERROR" to be returned. Likewise, using the write com-

2.9
AT+CFUN Set phone functionality
The AT+CFUNcommand 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 permanently blocks the serial interface. The benefit of the CYCLIC SLEEP mode 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. This allows the ME to wake up for the duration of an event and,
afterwards, to resume power saving. Please refer to Section 2.9.1, Wake up the ME from SLEEP mode for a
summary of all SLEEP modes and the different ways of waking up the module.
For CYCLIC SLEEP mode 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 0.9-2.7 seconds in order to indicate to the application
when the UART is active. The default setting of hardware flow control is AT\Q0 which must be altered to AT\Q3.
If both interfaces ASC0 and ASC1 are connected, hardware flow control must be set in either application.
The AT+CFUNwrite command can be used to reset the ME, to choose one of the SLEEP modes or to return to
full functionality.

NON-CYCLIC SLEEP mode:
In this mode, the AT interface is not accessible. Consequently, after setting
<fun>=0, do not send further characters. Otherwise these characters remain
in the input buffer and may delay the output of an unsolicited result code.
Due to the fact that the serial interface is disabled, this mode cannot be used
if a Remote SIM Access (RSA) connection is ongoing (reason: during RSA
connections the SIM communication is routed via a serial channel).
The first wake-up event stops power saving and takes the ME back to full func-

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

9
CYCLIC SLEEP mode:
In this mode, the serial interface is shortly enabled while CTS is active. If char-
acters 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.
CYCLIC SLEEP mode:
In this mode, the serial interface is shortly enabled while CTS is active. If char-
acters are recognized on the serial interface, the ME stays active after the last
character was sent or received for at least the time, which can be configured
In contrast to SLEEP mode 7 assertion of RTS can also be used to temporarily
wake up the ME. In this case too, activity time is at least the time set with
either from ASC0 or ASC1.

Notes
•
If both serial interfaces ASC0 and ASC1 are connected, any functionality level set with AT+CFUNtakes effect
on both of them. In Multiplex mode, the CFUN profile is shared by all multiplexer channels.
•
If the ME is in Multiplexer mode, it is not recommended to activate SLEEP mode with AT+CFUN=<fun>. The
best approach to properly control SLEEP mode in this case is to issue the PSC messages described in [5],
Section "Power saving control".
•
•
When a circuit-switched call is in progress, <fun>=7 or 9 can be activated without terminating the call. How-
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^SSYNCand [2]). With AT^SSYNCyou can select differ-
ent modes of LED signalization during SLEEP modes (see Section 19.6.1, ME status indicated by status LED
patterns 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 cov-
erage, 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.
2.9.1
Wake up the ME from SLEEP mode
A wake-up event is any event that causes the ME to draw more current. Depending on the selected mode, the
wake-up event either switches the SLEEP mode off and takes the ME back to full functionality AT+CFUN=1, or
activates the ME temporarily without terminating the selected SLEEP mode.
•
•
Quit: ME exits SLEEP mode.
Temporary: ME becomes active temporarily for the duration of the event and the mode-specific follow-up time
after the last character was sent or received on the serial interface.
•
No effect: Event is not relevant in the selected SLEEP mode. The ME does not wake up.

AT^SMSO Switch off mobile station
AT^SMSOinitiates the power-off procedure. High level of the module's PWR_IND pin and the URC "^SHUTDOWN"
notify that the procedure has completed and the module has entered the POWER DOWN mode. Therefore, be
sure not to disconnect the operating voltage until PWR_IND is high or until the URC "^SHUTDOWN" is displayed.
Otherwise, you run the risk of losing data. For further details on how to turn off the module see the [2].

Notes
•
•
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 phys-
ical serial interface (ASC0). The URC will be transmitted at the bit rate last activated on ASC0 for use with
the Multiplex driver.

“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

This parameter specifies the AT command(s) to be launched automatically. Each AT command is executed in
the same way as if it were entered online, this means that 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

This parameter can be used to query or configure the wake up time for power saving mode 9 (see AT+CFUNwith

<rba>(str)(+CSCS)
Allowed radio band(s)
The parameters <rba>, <rbp>and <rbc>allow the subscriber to set and query preferences for selecting fre-

Before changing <rba>or <rbp>ensure that no network activity occurs. The write command cannot be exe-
cuted when making a call, sending or receiving short messages or when the mobile is not registered, but search-
ing for a network. Therefore, to keep track of the module's registration state when changing the band
configuration, it is recommended to activate the URC "+CREG" first (see Section 8.4, AT+CREG). For example,
the URC "+CREG: 2" indicates that the ME is in network search mode. In this mode any attempt to change the
band parameters will be rejected with ERROR.
Execution of the write command causes the ME to deregister from and re-register to the network, no matter
whether the selected <rbp> or <rba> setting really changes. In this case too, it is useful to have the URC
The status of the SIM PIN authentication remains unchanged, eliminating the need to enter the SIM PIN again

The parameter <rba>determines the maximum range of the bands allowed. The value may be one of the single
bands listed below or all valid combinations from the values 1, 2, 4 and 8. Thus, the value range of <rba>is

Voice Message Waiting Indication for line 1
0
The value 0 notifies that no new voice message is available, and is pro-

the subscriber has retrieved all voice messages.
1
The value 1 notifies the subscriber that the mailbox contains one or
several messages.
"vmwait1" and "vmwait2" indicate the receipt of a special short message with
a Voice Message Waiting Indicator. The service must be provisioned by the
operator.
The numbers 1 or 2 in "vmwait1" and "vmwait2" are related to the two lines of
the Alternate Line Service (ALS), also defined in CPHS Phase 2 standard. For
The presentation mode of the indicator varies with the operator: If more than
one message are waiting, some operators only indicate the first one, others
deliver the indicator each time a new voice message is put into the mailbox.

After the subscriber has retrieved all voice messages the service center auto-

Some operators may also send the number of waiting voice messages along
with the indication. In this case, the number will be displayed by the TC63 as
part of the URC. For example, "+CIEV: vmwait1,1,5" notifies that five new voice
messages are waiting. However, it should be noted that neither the read com-

Current call or SMS is not ciphered.
Current call or SMS is ciphered.
As stated in GSM specifications 02.07 and 02.09 the ciphering indicator feature
allows the TC63 to detect that ciphering is not switched on and to indicate this
to the user.
The ciphering indicator feature may be disabled by the home network operator
setting data in the "administrative data" field (EFAD) in the SIM, as defined in
GSM 11.11.
If this feature is not disabled by the SIM, then whenever a connection is in
place, which is, or becomes unenciphered, an indication shall be given to the
user. This enables the user's decision how to proceed.
Read command returns valid ciphering status only if a call is in progress or
active.
If EFAD setting disables the ciphering indicator feature read command always
indicates a ciphered link and no URC presentaion will take place.
The following restrictions apply if the same serial channel is used for AT^SIND
"ciphcall" indication and for the action triggering this URC. In general, the rec-
ommended solution is to use a dedicated channel for all status signalling via
URCs.

“eons“
Enhanced Operator Name String (EONS) Indication
The Enhanced Operator Name String indicator feature allows the TC63 to out-
put various operator names for different PLMN identities via URC. It also allows
the output of a different operator name based on a subset of the registered net-
work by using a range of Location Area Codes (LACs) or a single LAC.
The presentation of the "eons" indicator is determined by network activity. For
example, the indicator appears every time a location update occurs or a NITZ
information is sent, no matter whether or not the status of the EONS informa-
tion has changed. This means that the same EONS information may be
reported several times.
The EONS tables are stored in the SIM card and will be read at power-up.
Following are the SIM Elementary Files that are affected by the introduction of
EONS feature in the SIM card:
EFSST (SIM Service Table) - describes which features are active.
EFOPL (Operator PLMN List) - contains the PLMN identification and location ID
together with the index of the corresponding PNN record
EFPNN (PLMN Network Name) - contains the full and short form version of the
network name for the registered PLMN
If the Operator Name Source is CPHS Operator Name String long and short
used:
EFONString (Operator Name String) - contains the name of the PLMN operator
who issued the SIM.
EFOPShort (Operator Name Short form) - contains a short form of the name of
the PLMN operator who issued the SIM.
“nitz“
Network Identity and Time Zone indication
This indicator shows the time relevant information elements of an MM Informa-
tion (MMI) or GMM Information (GMMI) message received from the network
(see GSM 24.008, ch. 9.2.15a and 9.4.19). The network usually sends a NITZ
indicator when the mobile attaches to the network, when it enters a location
area with different time zone or when a daylight change occurs.
A NITZ indicator may consist of the following parameters: Universal Time (UT),
local Time Zone (TZ), Daylight Saving Time (DST). All information elements of
MMI/GMMI are optional and therefore, the presentation of the parameters
network may send all three parameters UT, TZ, DST, or only UT and TZ or only
TZ.
UT is indicated in usual date/time format and represents the current world time
(GMT) at the moment when sent.
TZ is given as a positive (east) or negative (west) offset from UT in units of 15
minutes.
DST shows the number of hours added to the local TZ because of daylight sav-
ing time (summertime) adjustment. Usually DST is 1 hour but it can be also 2
hours in certain locations.
Example for time and time zone with DST:
+CIEV: nitz,"04/07/23,13:39:20",-28,1
In this example TZ is -28, showing a time offset of -7 hours (west) to Universal
Time/GMT (which never changes for DST). DST is 1 which indicates that one
hour was added to TZ because of Daylight Saving Time. If a network does not
send the DST parameter the TZ value would be -32 (8 hours west) as would
be done in winter:
+CIEV: nitz,"04/11/23,13:39:20",-32
Please be aware that despite the last NITZ value can be looked up again via
"AT^SIND=nitz,2" the returned values may be out of date. Especially the UT
value is obsolete because there is no internal NITZ clock and therefore no con-
tinuation of UT.
NITZ values are lost when the module detaches from network. Also when a

Notes specific to the EONS feature:
If the indicator is "eons", the <indValue>is a type associated to the operator name according to GSM 22.101
[25]. This type depends on the source of the operator name.
Priority of types associated to the operator names is defined as follows (the type listed first has the highest pri-
ority). If a type cannot be indicated the next one will be used.

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.
TC63's autobaud feature detects the bit rate currently used by the TE. However, this detection suffers some
limitations described in Section 4.9.1, Autobauding. If autobauding is enabled, the AT+ICFread command
does not show the current character framing, but the character framing that will be used when autobauding

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 inter-
nal value 'no parity' which is not supported by <format>=2. (Remember that if an optional parameter is omit-
ted 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 TE (DTE) and TA (DCE) are configured to the same rate. When you select autobauding, the TA will auto-
matically recognize the bit rate currently used by the TE.
The setting is stored in the non-volatile memory and will be used whenever the engine is powered up again. How-
ever, in case of autobaud mode (AT+IPR=0) the detected TA bit rate will not be saved and, therefore, needs to

Factory default is autobauding enabled (AT+IPR=0) on ASC0 and 57600bps on ASC1. It will not be restored
The current setting of AT+IPRwill be preserved when you download firmware (i.e. a firmware update does
not restore the factory setting) or in the event of power failure.
Generally, AT+IPRshould be used as a standalone command. If nethertheless combinations with other com-
mands on the same command line cannot be avoided, there are several constraints to be considered:

Take into account, that a delay of 100ms is required between the response to the last command (e.g. OK)

received.
following problem: if switching to the new bit rate takes effect while a response is being transmitted, the
last bytes may be sent with the new bit rate and thus, not properly transmitted. The following commands
will be correctly sent at the new bit rate.
•
In order to account for greater amounts of data it is recommended to choose a minimum bit rate of 2400 bps.
If the ME is operated in Multiplex mode we suggest a minimum bit rate of 4800bps.
•
•
A selected bit rate takes effect after the write commands returns OK (except for Multiplex mode).
In Multiplex mode, the write command AT+IPR=<rate>will not change the bit rate currently used, but the
new bit rate will be stored and becomes active, when the module is restarted.
4.9.1
Autobauding
To take advantage of autobaud mode specific attention must be paid to the following requirements:
•
Synchronization between TE and TA
Ensure that TE and TA are correctly synchronized and the bit rate used by the TE is detected by the TA. To
allow the bit rate to be synchronized simply use an "AT" or "at" string. This is necessary
-
-
after you have activated autobauding
when you start up the GSM engine while autobauding is enabled. It is recommended to wait 3 to 5 seconds
before sending the first AT character. Otherwise undefined characters might be returned.
If you want to use autobauding and autoanswer at the same time, you can easily enable the TE-TA synchro-
•
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.

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 autobaud
rupted.
When autobauding is switched on:
+ only data length, parity and baud rate are automatically detected
•
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 deter-
mined, the following constraints apply:
-
An incoming CSD call or a network initiated GPRS request cannot be accepted. This must be taken into
if SIM PIN 1 authentication is done automatically and the setting ATS0≠ 0 is stored to the user profile with
AT&W.
-
Until the bit rate is found, URCs generated after restart will be output at 57600 bps. This applies only to
user defined URCs, such as "+CREG", "CCWA", "^SCKS" etc. The URCs "^SYSSTART", "^SYSSTART
CHARGE-ONLY MODE" and "^SYSSTART AIRPLANE MODE" will not be indicated when autobauding is
enabled.
Note: To avoid any problems caused by undetermined bit rates in the direction from TA to TE we strongly
recommend to configure a fixed bit rate rather than autobauding.

4.10
AT+CMUX Enter multiplex mode
All information provided in this section applies to the ASC0 interface only. The second interface ASC1 has no
support of Multiplex mode.
Multiplex mode according to the ETSI TS 101 669 and GSM 07.10 enables one physical serial asynchronous
interface to be partitioned into three virtual channels. This allows you to take advantage of up to 3 simultaneous
sessions running on the serial interface. For example, you can send or receive data or make a call on the first
channel, while the other two channels are free to control the module with AT commands.
The TC63 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 mul-
tiplex programs conforming to the multiplexer protocol. To help system integrators save the time and expense of
designing multiplexer applications, SIEMENS AG offers WinMUX2k, a ready-to-use multiplex driver for Windows
2000 and Windows XP. Another approach is to develop customized solutions based on the sources of the
WinMux2k driver.
Refer to [5] which provides a detailed description of the multiplex architecture and step-by-step instructions of
how to install and configure the multiplex mode. The WinMUX2k driver and its source files can be supplied on
request. Please contact your local distributor to obtain the latest installation software and user's guide.

ASC1 is disabled when the multiplexer is enabled on the first serial interface ASC0. Yet, both ASC1 and the mul-
tiplexer channel 2 are using the same parameters, and thus, the same user defined profile (if any). As a result,
a user profile stored on multiplexer channel 2 takes effect on ASC1 after closing the multiplexer and starting up
ASC1. Likewise, a user profile stored on ASC1 will be loaded on multiplexer channel 2.
This may be a problem when ASC1 is not connected, but flow control (for example AT\Q1 or AT\Q3) is stored to
the user profile on the multiplexer channel 2. In this case, flow control takes effect on ASC1, when the multiplexer
is switched off. If then for example a large amount of URCs is generated, their transmission might be stopped
due to the flow control. To avoid this problem we recommend that you do not activate flow control on multiplexer

Notes
•
Caution: After entering a password with AT+CPINall 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
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.
TC63 offers various options to verify the present status of network registration: For example, the AT+COPS
command indicates the currently used network. With AT+CREGyou can also check the current status and acti-
vate 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.

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 oper-
able. 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:
•
•
PIN2 / PUK2:
PIN2 prevents unauthorized access to the features listed in AT+CPIN2. The handling of PIN2 varies with the pro-
vider. 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 per-
manently 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:
•
•
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 man-
ufacturer 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:
•
•
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 incor-
rectly three times, the client will need to contact the service provider to obtain a new one.

The read command returns an alphanumeric string indicating whether or not network authentication is required.
The write command allows the TC63 to store the entered password. This may be for example the SIM PIN2 to
benefit from the features listed below, or the SIM PUK2 to replace a disabled PIN2 with a new one. Note that
PIN2 can only be entered if PIN1 authentication was done.
If the TC63 is requesting SIM PUK2, use <pin>to enter the PUK2, followed by <new pin>to specify the new

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.
See examples below for further details.
“SC“
“PS“
SIM (lock SIM cards). SIM requests password upon ME power-up and when
this lock command is issued.
<password>: SIM PIN1.
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". Accord-
ingly, 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.

5.4 AT+CLCK
s
<password>: User defined password. It is needed before the first use of
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 num-
bers stored to the "FD" memory can be dialled. (Capacity of FD phonebook
depending on the SIM card).
<password>: SIM PIN 2.
If a lock on the SIM fixed dialing memory is active, the following applies:
•
Outgoing voice, data or fax calls can be made only to numbers stored in
''FD'' phonebook.
Result code depends on the type of the call:
for voice calls, indication is ''+CME Error 257: Call barred''.
for data and fax calls, indication is ''NO CARRIER''.
•
Access to defined Supplementary Services such as Call barring, Call wait-
ing, Call forwarding, Call hold and Multiparty is possible only if the exact cor-
responding 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 dial-
ling numbers'' phonebook ''FD''.
Also a valid Service Center Address (international format) must be present
in ''FD'' to allow sending SMS at all.
Indication is ''+CMS Error 302: operation not allowed''.
GPRS commands can be used only if the ''fixed dialling numbers'' phone-
book ''FD'' contains an entry with phone number ''*99#''. This single entry
enables all GPRS commands, including AT commands and modem com-
patibility commands like ''ATD*99***1#'' or ''ATD*98***1#''.
Indication is ''+CME Error 257: Call barred''.
Factory defined SIM locks:
Typical examples of factory set SIM locks are prepaid phones or network locks, used to restrict the operation of
a mobile to a specific provider or operator. The client should be aware that each of these lock types can only be
unlocked if the associated password is available. For example, a mobile can be locked to accept only SIM cards
from the respective provider, or even one single SIM card. Once a different SIM card is inserted the ME will
prompt the client to enter a specific code. This is not the PUK of the SIM card, but usually an 8-digit code which
needs to be requested from the provider.
The locks can only be set by the manufacturer and need to be agreed upon between the parties concerned, e.g.
provider, operator, distributor etc. on the one side and the manufacturer on the other side. For details contact
your local dealer or Siemens AG.

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 pack-
age.
When you attempt to set a <facility>or <class>which is not provisioned, not yet subscribed to, or not sup-
ported 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: Oper-
ation not supported" etc.). To make sure check the extended error response with AT+CEERand the lock status

Parameter Description
<facility>(str)
Phone security locks set by client or factory:
Primarily intended for the client to take safety precautions, passwords "SC" (SIM PIN) and "P2" (SIM PIN2) are
usually predefined, but can be configured individually. The password for lock facility "PS" may also be factory
set.
“SC“
SIM PIN. SIM requests password upon ME power-up and when this lock com-
mand is issued.
If incorrectly entered three times, the SIM PUK is required to perform authen-
tication. Input of the SIM PUK password is possible only with AT command
<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". Accord-
ingly, 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
<password length>: 4 digits.
If incorrectly entered three times, the Master Phone Code is required to lift the
new phone code ("PS" password for lock facility), if desired.
Mind that successful PIN authentication is a prerequisite for use of AT com-
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
“P2“
If incorrectly entered three times, the SIM PUK 2 is required to perform authen-
tication. Input of the SIM PUK 2 password is possible only with AT command
<password length>: 4 to 8 digits.
Factory defined SIM locks:
Typical examples of factory set SIM locks are prepaid phones or network locks, used to restrict the operation of
a mobile to a specific provider or operator. The client should be aware that each of these lock types can only be
unlocked if the associated password is available. For example, a mobile can be locked to accept only SIM cards
from the respective provider, or even one single SIM card. Once a different SIM card is inserted the ME will
prompt the client to enter a specific code. This is not the PUK of the SIM card, but usually an 8-digit code which
needs to be requested from the provider.
The locks can only be set by the manufacturer and need to be agreed upon between the parties concerned, e.g.
provider, operator, distributor etc. on the one side and the manufacturer on the other side. For details contact
your local dealer or Siemens AG.

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 pack-
age.

AT^SPWD Change Password
The AT^SPWD command comprises all functions of the AT+CPWD command. Apart from the different prefixes
"^SPWD" and "+CPWD", the major difference is that the <facility>list of AT^SPWDincludes the additional
"CM" password dedicated to the Customer SIM Lock. Set with the command AT^SCSL, this type of lock allows
the application manufacturer to lock a mobile to specific operators.
The Customer SIM Lock feature is designed to be configurable during the production of the mobile application.
Therefore, to program the "CM" password, the AT^SPWDwrite command can be used no matter whether the SIM
is inserted or PIN authentication has been done. Opposite to that, passwords for all other facilities can only be
edited if the SIM is present and PIN authentication completed.
IMPORTANT: Please note that, even though there is no need for a factory set Customer SIM Lock, you are
strongly advised to specify at least a "CM" password, avoiding that end users ever have a chance to activate this
lock type.
Each password is a string of digits the length of which varies with the associated facility. The test command
returns a list of pairs which represent the available facilities and the maximum length of the associated password.
See also AT commands AT+CLCKand AT^SLCKas well as AT^SCSLfor more detail on the various lock features.

Data of the allowed network operators.
Each operator code consists of the "Mobile Country Code" MCC and the "Mobile Network Code" MNC, both sep-
arated by a dot, e.g. MCC1.MNC1. If more than one operator is entered on the same line, then a colon must be
set between each operator code, e.g. MCC1.MNC1:MCC2.MNC2:MCC3.MNC3. For example, for the three
operators T-Mobile D, Vodafone D2 and E-Plus you would enter the following data: 262.01:262.02:262.03
Note that each time the AT^SCSLwrite command is executed using the parameter <action>=1 the existing
operator codes will not be overwritten, but all new data will be added to the list. This applies no matter whether
the same operator code is already listed, i.e. entering the same operator again causes double entries.
The maximum number of entries in the operator list is 50.

All parameters of AT^SCSLas well as the "CM" password of AT^SPWDcan be used no matter whether or not

operators.
AT^SCSL="PN",0,password. This will delete both the <PUK>and the list of operators. The mobile will accept
any SIM card.
Another way to operate the mobile with other SIM cards is to deactivate the Customer SIM Lock using the
command AT+CLCK="PN",0,PUK. This will delete the list of operators specified with the Customer SIM Lock,
If the Customer SIM Lock is deactivated and, therefore, operable with any SIM card, the end user may use
the <PUK>to set a new SIM lock. To do so, it is necessary to enter the command AT+CLCK="PN",1,PUK first,
then insert a different SIM card and finally restart the mobile. When restarted, the mobile will read out and
accept the list of operators of the currently inserted SIM card. As a result, a new Customer SIM Lock takes
effect for the operator(s) listed on this SIM card.
•
•
If the Customer SIM Lock is active, but the end user inserts an unsupported SIM card and enters PIN1 the
mobile returns OK, although access to SIM related commands (such as dialing out, access to phonebooks,
SMS etc.) will be denied. If then the read command AT+CPINis executed the mobile will request the PH-NET
PUK. In this case, you have two options: Use the AT+CPINcommand to enter the correct <PUK>of the Cus-
tomer SIM Lock. After this, the mobile can be operated with the new SIM card. As an alternative, re-insert the
correct SIM card associated with the Customer SIM Lock and deactivate the lock via AT+CLCK="PN",0,PUK.
If an invalid <password>or <PUK>is entered several times in succession, a delay incremented after each
failed attempt will increase the time to wait before the next input is accepted. The delay follows the same tim-
ing algorithm specified for the PH-SIM PUK (Master Phone Code). For details regarding the delay see Section

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

when a state transition ends in state "active" or in state "unknown" (if AT^SCFGsetting <sucs>="restricted")

Due to compatibility considerations, the powerup default for AT^SCFG setting <succ> is "restricted", offering
compatibility to the standard behaviour of indicator "+CIEV: call", while the default for setting <sucs>is "ver-
bose".
In order to see the URCs, event reporting for both indicators must be explicitely configured with the appropriate
AT commands.

Notes
•
•
Any additional commands on the same command line are ignored.
The command may be aborted generally by receiving a character during execution. It can't be aborted in
some connection setup states, such as handshaking.
•
If AT+FCLASSsetting is 1 or 2, all incoming calls will be answered as fax calls, when ATA is issued on multi-
plexer channel 1 resp. ASC0. For calls explicitly signalled as voice or data calls, this procedure will fail with
result code "NO CARRIER", but the call in question will continue to ring.
It is possible to change the setting for AT+FCLASSto 0 while the call is ringing, and accept the call normally
•
•
•
The ATA command may be used also to accept a network request for a PDP context activation (see ATA).
If an incoming call is no longer available (already disconnected/hanged up)a "NO CARRIER" result code will
be given.

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.
•
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 ter-
minates successfully or unsuccessfully).
•
For data connections, call setup always terminates when the call has been established (indicated by the result
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+CEERor ATS18
should be used for all applicable connections.
•
When a user originates a second voice call whil there is already an active voice call, the first call will automat-
ically 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 CAR-
RIER", "NO DIAL TONE", "NO CARRIER" will be presented afterwards (see example below).
Parameter Description
<n>(text)
String of dialing digits and optional V.250 modifiers: 0-9, *, #, +, A, B, C
The following V.250 modifiers are ignored: ,(comma), T, P, !, W ,@
Emergency call : <n> = 112, 911 or 08, standardized GSM emergency number (no SIM needed).

•
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.
Example
The following example shows the call setup procedure when a call is already active and a second call attempt
fails because the line of the called party is busy:
atd03012345678
Dialing out the first party's number.
OK
The first call is established.
ATD03022222222
OK
The number of the second party is dialed.
The response "OK" is issued immediately though no call is established

•
•
•
This command works for MT data and fax 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 hang up before the call is automatically answered.
Example: Call setup may fail if ATS7=30 and ATS0=20.
•
Setting is local to the interface. It is allowed to have different settings on different interfaces. In such cases
•
•
The ATS0 write command is PIN protected.
The command ATS0 is also used as GPRS compatibility command to answer automatically to a network
request for PDP context activation (for details see ATS0for GPRS). So using ATS0=<n>with n > 0, will per-
form a GPRS attach, if the ME is not already GPRS attached and if ME is configured to do so (see AT^SCFG,
parameter <gs0aa>). If the GPRS attach fails (e.g. the network rejects the attach request), the write com-
mand returns an error, though the new value takes effect.
The GPRS attach will not be performed on recalling a stored user profile with ATZor on powerup, if a n > 0

ATS7 Set number of seconds to wait for connection completion
ATS7specifies the number of seconds the TA will wait for the completion of the call setup when answering or
originating a data call. Also referred to as "no answer timeout". To put it plainly, this is the time to wait for the
carrier signal. If no carrier signal is received within the specified time, the TA hangs up.

Command Description
This command is only available during a CSD call or a GPRS connection. The +++ character sequence causes
the TA to cancel the data flow over the AT interface and switch to command mode. This allows you to enter AT
commands while maintaining the data connection to the remote device or, accordingly, the GPRS connection.
To prevent the +++ escape sequence from being misinterpreted as data, it must be preceded and followed by a
pause of at least 1000 ms. The +++ characters must be entered in quick succession, all within 1000 ms.
Notes
•
•
In Multiplex mode the +++ sequence does not work. Therefore, if required in Multiplex mode, the escape
sequence needs to be implemented in the customer's external Multiplex application. Design solutions, for
•
On ASC1 the +++ sequence can be used in GPRS connections for switching from PPP online to command
mode.

•
If a URC "^SLCC" in verbose mode (see AT^SCFG) has been buffered while the interface was in dedicated
mode (depending on the settings of AT+CMERparameter <bfr>), each buffered event indicator will be output
as a separate URC after the interface returns to idle mode.
However, the output will deliver the list of current calls in the "current" state (at the time when the output is
generated), possibly leading to multiple displays of identical list configurations.
•
Some parameters of AT command AT+CHLD, as well as some situations where the call status in the network
changes very quickly (e.g. the transition between <stat>= ''unknown'', ''dialing'' and ''alerting'' for a call to a
reachable subscriber within the registered network) may lead to quasi-simultaneous changes to the states of
one or several calls in the list, possibly leading to multiple displays of identical list configurations.
•
•
If multiple displays of identical list configurations occur, this happens because of intermediate states of the
list, that have already been overridden by new transitions and states. Thus, it is guaranteed that the configu-
ration displayed in such cases is the current configuration at the time of the last display.
It is adviseable to receive URC "^SLCC" on an interface that is not used for call initiation, if verbose output is
configured. If only voice calls are expected, a setting of AT^SM20= 0 may be used alternatively in order to
keep the call from blocking the interface.

Command Description
The AT+CSNScommand enables the ME to accept incoming calls when no bearer capability information is pro-
vided with the call, e.g. single numbering scheme calls or calls originitating from analog devices.
Parameter Description
<mode>(num)
[0](D)
Voice: Each call received without bearer element is assumed to be speech
2
Fax: Each call received withoutbearer element is assumed to be an incoming
fax.
4
Data: Each call received without bearer element is assumed to be a data call.
Please take into account that the bearer service parameters set with AT+CBST
apply to all data calls including those received without bearer capability.
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.
•
The setting will be automatically saved when you power down the GSM engine with AT^SMSO, provided that
PIN authentication has been done. This value will be restored when PIN authentication is done again.

AT+COPS Operator Selection
AT+COPSqueries the present status of the TC63's network registration and allows to determine whether auto-
Three operator selection modes are available:
•
Automatic
TC63 searches for the home operator automatically. If successful the TC63 registers to the home network. If
the home network is not found, TC63 goes on searching. If a permitted operator is found, TC63 registers to
this operator.
If no operator is found the TC63 remains unregistered.
•
•
Manual
Desired operator can be determined using the AT+COPSwrite command. If the operator is found, TC63 reg-
isters to it immediately. If the selected operator is forbidden, the TC63 remains unregistered.
Manual/automatic
The ME first tries to find the operator determined via AT+COPSwrite command. If the is able to register to this
operator, it enters the manual operator selection mode. If the ME cannot find this operator or fails to register
to this operator, then it enters the automatic operator selection mode and starts to select the home operators
network or another (permitted) one.
The most recently entered operator selection mode is still valid after the ME was restarted (power-off/on).
The AT+COPStest command lists sets of four parameters, each representing an operator present in the network.
A set consists of
•
•
•
an integer indicating the availability of the operator,
long alphanumeric format of the operator's name and
numeric format representation of the operator.
Any of the parameters may be unavailable and will then be an empty field (,,). The list of operators comes in the
following order: Home network, networks referenced in SIM and other networks.
The operator list is followed by a list of the supported <mode>s and <format>s. These lists are delimited from
the operator list by two commas.
If the test command is used during an ongoing GPRS transfer, traffic will be interrupted for up to one minute.
The AT+COPSread command returns the current <mode>and the currently selected operator. If no operator is
The AT+COPSwrite command forces an attempt to select and register to the GSM network operator (see note

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'.

'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 reselec-
tion 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),

Otherwise, on the one hand, a waiting caller would be kept waiting due to lack of BUSY signals, while, on the

when you attempt to enable call waiting for a <class>for which the service is not provisioned or not sup-

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 imple-
mentation of the service. For example, the activation of call waiting for <class>4, "fax", causes some net-
works 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

Command Description
TA controls the Supplementary Services Call Hold and Multiparty. Calls can be put on hold, recovered, released,
and added to a conversation.
Like for all Supplementary Services, the availability and detailed functionality of Call Hold and Multiparty services
depends on the configuration of the GSM network. The TC63 can only request the service, but the network
decides whether and how the request will be answered.
Parameter Description
<n>(num)

Notes
•
The AT+CHLDcommand offers a broad range of options according to the GSM specifications. However, if you
attempt to invoke an option which is not provisioned by the network, or not subscribed to, invocation of this
option will fail. The responses in these cases may vary with the network (for example "Operation not allowed",
"Operation not supported" etc.).
•
The handling of the supplementary service Call hold and Multiparty varies with the types of calls. This is
because only voice calls can be put on hold, while data or fax calls cannot. The following procedures apply:
With AT+CHLD=2 the user can simultaneously place a voice call on hold and accept another waiting voice,
data or fax call. If the waiting call is a data or fax call, it is also possible to put the voice call on hold. To switch
back from the active data or fax call to the held voice call the active call must be terminated with AT+CHLD=1.
If all active and held calls are voice calls it is possible to switch back and forth with AT+CHLD=2.
•
•
In conflict situations, e.g. when a waiting call comes while there are already held calls, the above procedures
apply to the waiting call only. For example, <n>=0 rejects the waiting call, but does not affect the held calls.

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. Lead-
ing 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.

10. Internet Service Commands
s
10.
Internet Service Commands
TC63 has an embedded TCP/IP stack that is driven by AT commands and enables the host application to easily
access the Internet. The advantage of this solution is that it eliminates the need for the application manufacturer
to implement own TCP/IP and PPP stacks, thus minimizing cost and time to integrate Internet connectivity into
a new or existing host application. This chapter is a reference guide to all the AT commands and responses
defined for use with the TCP/IP stack.
Access is provided to the following Internet Services:
1. Socket Client and Server for TCP, Client for UDP
2. FTP Client
3. HTTP Client
4. SMTP Client
5. POP3 Client
Step-by-step instructions on how to configure and use TCP/IP communications with TC63:
•
First of all, create a connection profile with AT^SICS. The connection profile is a set of basic parameters
which determines the type of connection to use for an Internet service. Up to 6 connection profiles can be
•
Secondly, use AT^SISSto create a service profile based on one of the connection profiles. Up to 10 service
profiles can be defined, each identified by the <srvProfileId>. The service profile specifies the type of
Internet service to use, i.e. Socket, FTP, HTTP, or one of the email services SMTP or POP3. To assign a
connection profile to a service profile, the <conProfileId>of AT^SICSmust be entered as "conId" value
This offers great flexibility to combine connection profiles and service profiles. For example, you may have
one connection profile (CSD or GPRS) specified with AT^SICSwhich can be associated with an SMTP ser-
vice profile for sending emails and a POP3 service profile for retrieving emails.
•
•
•
Once the connection profile and the service profile are created, an Internet session can be opened by entering
The next command determines the action to be performed, for example reading data with AT^SISRor writing
Maximum number of profiles defined / used:
•
•
Up to 10 service profiles can be created (with AT^SISS), but the number of parallel profiles of the same ser-
vice type is limited as listed below. If the maximum number of a service profile type is already defined, any
attempt to set up another profile for the same type will be denied with "+CME ERROR: unknown".
-
-
Maximum 3 HTTP profiles
Maximum 6 socket profiles: Only 2 instances can be opened for listener, meaning that if 2 listeners are
established another 4 instances can be opened for clients. Also, the socket service can accept an incom-
ing connection only when at least one service profile is still free (not yet created with AT^SISS), otherwise
the incoming connection will be rejected from the listener. If there is no listener established all 6 socket
profiles can be configured as client.
-
-
-
1 FTP profile
1 POP3 profile
1 SMTP profile
•
•
The TCP/IP stack of TC63 supports using several service profiles at the same time, provided all of them are
running on the same connection profile. For example, it is possible to download files from an FTP server, while
sending and receiving emails at the same time.
GPRS connections established over the Dial-Up Network do not use the embedded TCP/IP stack of TC63
TC63_ATC_V00.490

TC63 AT Command Set
s
and can be active at the same time. This allows the user to have two parallel GPRS connections: for example
for sending or receiving emails over a GPRS connection enabled by the TCP/IP stack while, at the same time,
surfing the Internet over a Dial-Up Network GPRS connection.
Using Internet Service AT commands on several interfaces (ASC0, ASC1, USB or Multiplex mode on ASC0):
•
•
A connection profile can be created on one interface and then viewed or changed on all other interfaces.
A service profile can be used only on one interface at a time:
-
Changes to a service profile are allowed only on the same interface where it was created, trying to change
it on another interface is denied with "+CME ERROR: Invalid index". If queried with the read command
AT^SISSthe entire profile is returned on the interface where the service profile was created, while on all
other interfaces only the service type of the profile is stated.
-
-
If a service profile is active (after opening it with AT^SISO) on one interface, any attempt to open or close
the same service profile on another interface is denied with "+CME ERROR: Operation temporary not
allowed".
To free a service profile for use on another interface, use the AT^SISScommand and select service type
= "none". This action deletes the entire profile and restores all parameters of the profile to their initial
power-up state (all values are empty). For example, to remove the service profile 3, set AT^SISS=3,svr-
type,none. After this, a new profile 3 can be created on any other interface.
Address notation
Server addresses must be provided as IP addresses in standard dot-format (e.g. "192.168.1.2") or as server
address names resolvable by a DNS server (e.g. "smtp.myserver.de" or "pop3.myserver.de").
Inactivity timeouts
Inactivity timeouts are not part of the Internet AT command functionality implemented in TC63 and, if desired,
are the responsibility of the host application. It is recommended that the host application validates URCs and AT
command responses and reacts adequately, for example by sending a close message or starting a timer.

hcAuth
Parameter for several HTTP settings.
The general format is 'key': <space> 'value' "\0d\0a".
Multiple settings can be given separated by "\0d\0a" sequences within the
string.
Possible 'key' values are defined at HTTP/1.1 Standard RFC 2616.
This flag controls the redirection mechanism of the TC63 acting as HTTP client
(numeric).
If the flag is set (1) the client automatically sends a new HTTP request if the
server answers with a redirect code (range 30x).
Default is 0 (no redirection).
If set (1) this flag determines that the HTTP client will automatically answer on
authentication requests from the server with the current "passwd" and "user"
parameter settings. If these parameters are not specified the TC63 will termi-
nate the HTTP connection and send an indication to the TA.
Default is 0.

A valid address parameter consists of local part and domain name delimited by
a '@' character, e.g. "[email protected]".
Recipient address of the email, i.e. "RCPT TO" address (string).
Length: 6 ... 256
If multiple recipient addresses are to be supplied the comma character is used
as delimiter to separate individual address values, e.g. "john.smith@somedo-

pLength
Maximum message length (string, optional)
Length: 0 ... 232-1
"pLength" can be used to specify the length of the message(s) to be retrieved
from or deleted on the POP3 server. If no specific value is set in the service
profile, the default value "0" is assumed, which means that there is no limit on
the message size.
A warning will be issued inthe following cases:
•
If "pNumber" > 0 and a specific message to be retrieved from / deleted on
the server is longer than "pLength".
•
If "pNumber" = 0 and all messages to be retrieved from / deleted on the
server are longer than "pLength".
No warning will be issued in the following cases:
•
•
If there are no messages at all on the server.
If the server has message(s) below and above the "pLength" specified. In
this case, the message(s) within the range of "pLength" can be successfully
retrieved or deleted, but the message(s) above "pLength" remain on the
server without any further notification given to the user.
•
Therefore, after retrieving / deleting messages, it is recommended to check
the message status on the server. This can be done by adding a further
POP3 service profile using the POP3 user command List ("2").
pDelFlag
Flag to be used with the POP3 user command Retrieve ("3"). Specifies whether
or not to delete retrieved emails on the server (optional).

for this specific service profile you can change its server type. Otherwise, changing the server type would imme-
diately deregister the service (i.e. its TCP/IP connection would be immediately shut down).

Command Description
The test command is used for requesting information on the supported PDP context activation states.
The read command returns the current activation states for all the defined PDP contexts.
The write command is used to activate or deactivate the specified PDP context(s). After the command has com-
pleted, the MT remains in V.250 command state. If any PDP context is already in the requested state, the state
for that context remains unchanged. If the MT is not GPRS attached when the activation form of the command
is executed, the MT first performs a GPRS attach and then attempts to activate the specified contexts. If no
<cid>s are specified the activation/deactivation form of the command activates/deactivates all defined contexts.
Parameter Description
<state>(num)
Indicates the state of PDP context activation.

Notes
•
•
If the MT is in dedicated mode, the write command returns "+CME ERROR: operation temporary not allowed".
A maximum of 2 contexts can be activated at the same time, no matter on which interface. Trying to activate
more than 2 contexts will cause "+CME ERROR: operation temporary not allowed". Note that, depending on
the provider, the number of activated contexts may be further restricted.
•
If an activated context will be deactivated without using the command AT+CGACT, then the result code "NO
CARRIER" will be issued to indicate the context deactivation. This happens for example if the context deac-
tivation is forced by the network or if deactivation results from a network deregistration with AT+COPS=2.

During the PDP startup procedure the MT has the PDP type and the PDP address provided by the network
in the Request PDP context activation message. If this is in conflict with the information provided by a spec-
ified <cid>, the command will fail. There will be no conflict, if the PDP type matches exactly and the PDP
address given by the context definition for <cid>is empty or matches exactly with the address specified with
the network PDP context activation message.
The context will be activated using the values for PDP type and address provided by the network, together
with all other information found in the PDP context definition. An APN may or may not be required, depending

The test command is used for requesting information on the supported GPRS service states.
The read command returns the current GPRS service state.
The write command is used to attach the MT to, or detach the MT from the GPRS service. After the command
has completed, the MT remains in V.250 command state. If the MT is already in the requested state, the com-
mand is ignored and the OK response is returned. Any active PDP contexts will be automatically deactivated
when the attachment state changes to detached.

When the module is GPRS attached and a PLMN reselection occurs to a non-GPRS network or to a network
where the SIM is not subscribed to for using GPRS, the resulting GMM (GPRS mobility management) state
according to GSM 24.008 is REGISTERED/NO CELL, meaning that the read command will still show

Command Description
The test command is used for requesting information on the supported layer 2 protocols to be used between the
TE and MT.
The write command causes the MT to perform all actions which are necessary to establish communication
between the TE and the network using one or more GPRS PDP types. This may include performing a GPRS
attach and one or more PDP context activations. Commands following the AT+CGDATAcommand in the AT com-
mand line will not be processed by the MT.
If no <cid>is given or if there is no matching context definition, the MT will attempt to activate the context with
PDP type IP and all other context parameters set to their default values (see AT+CGDCONT, AT+CGQREQ,
If the write command is successful, the MT issues the intermediate result code CONNECT and enters V.250
online data state.
After data transfer is complete, and the layer 2 protocol termination procedure has completed successfully, the
command state is reentered and the MT returns the final result code OK.
In the event of erroneous termination or a failure to start up, the command state is reentered and the MT returns
NO CARRIER, or if enabled +CME ERROR.
Parameter Description

If the MT is in dedicated mode, write command returns "+CME ERROR: operation temporary not allowed".
It is possible to leave the GPRS data mode and enter the command mode by using the V.250 command +++.
If no <cid>is specified, this is equivalent to using the V.250 command ATO, which is usable for GPRS con-
nections too. In this case the first context will be used, which is active and already in data mode since it has
been activated.
It is possible to use AT+CGDATAto enter the data mode for a context, which is not yet in data mode since it
11.5.1 Automatic deactivation of PDP context during dial-up PPP
code CONNECT and enters V.250ter online data state. In V.250 online data state, first some LCP protocol
exchange between MT and TE is performed to set up the PPP link. After successfully establishing the PPP link,
the MT performs the PDP context activation procedure if the context is not already activated. As a result, the MT
is in a "PDP context activated" state within the PLMN, the PPP link is established on the mobile side and the
mobile is ready for IP data transfer.
If the TE wants to close the LCP link the MT may perform an LCP termination request procedure on PPP level.
After this LCP termination procedure the MT deactivates the PDP context automatically and the MT returns to
V.250 command mode and issues the final result code NO CARRIER.
During the implicit PDP context deactivation procedure after LCP termination the TE may change into V.250
command state (e.g. by using +++or by toggling DTR if AT&Dis set to 1) before the result NO CARRIER occurs.
In this case the application should not try to deactivate the PDP context by using the commands AT+CGACTor
ATH. If DTR is configured to disconnect data connections (AT&D2), then the application should not toggle DTR
during the implicit PDP context deactivation and before "NO CARRIER" is received.

Command Description
The test command returns supported values as a compound value.
The read command returns the current settings for each defined PDP context.
The write command specifies the parameters for a PDP context identified by the context identifier <cid>. The
number of contexts that may be in a defined state at the same time is given by the range returned by the test
command. A special form of the write command (AT+CGDCONT=<cid>) causes the values for context <cid>to
become undefined.
Parameter Description
<cid>(num)
PDP Context Identifier
Parameter specifies a particular PDP context definition. The parameter is local to the TE-MT interface and is
used in other PDP context-related commands.

The test command returns values supported as a compound value. If the MT supports several PDP types, the
parameter value ranges for each PDP type are returned on a separate line.
The read command returns the current settings for each defined context.
This command allows the TE to specify a minimum acceptable profile which is checked by the MT against the
negotiated profile returned in the Activate PDP Context Accept message.
The set command specifies a profile for the context identified by the (local) context identification parameter,
A special form of the set command, AT+CGQMIN= <cid> causes the minimum acceptable profile for context
AT&Fand ATZwill undefine the minimum QoS profiles of every context which is not active or not online.

•
If a network request for PDP context activation is answered automatically and another AT command is issued
at the same time on the same interface then this AT command will not be executed. Any response belongs
to the automatic context activation procedure. If the AT command which caused the collision was a CS data
call, the CONNECT response does not belong to this data call but to the GPRS. This can be detected if ATX
is not set to 0. CS data call will issue CONNECT <text>, GPRS will issue CONNECT only.
•
A network request for PDP context activation has a maximum duration of approximately 40 seconds (for
details see GSM 04.08). A RING/CRING URC is issued every 5 seconds, so setting parameter <n>to values
greater than 7 will not allow a successful context activation and is not recommended.
•
•
•
The automatic GPRS attach will not be performed on recalling a stored user profile with ATZor on powerup,
If the automatic GPRS attach fails (e.g. the network rejects the attach request), the write command returns
error, though the new value takes effect. This is necessary because ATS0is used for circuit switched calls too.
ATS0 write command is PIN protected.

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; imple-
mentation 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))
<ct>(num)

<da>(num)(+CSCS)
Destination Address
GSM 03.40 TP- Destination-Address Address-Value field in string format; BCD numbers (or GSM default alpha-
bet 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-User-
Data-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 TP-
User-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 hexa-
decimal numbers containing two IRA characters.

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
Concatenated short messages, 16-bit reference number
16
<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 char-
acters 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 charac-
ters.
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 max-
imum 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 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 mes-
sage 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.

If sending fails, for example, if a message is too long, the result code depends on the current setting of the
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.

•
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, "Back-
space" (ASCII character 8) does not delete a character, but will be inserted into the short message as an addi-
tional 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.

tional 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.
The length of 8-bit data coded short messages has to be greater than 0.

Command Description
The write / execute command confirms successful receipt of a new message (SMS-DELIVER or SMS-STATUS-
REPORT) routed directly to the TE. TA shall not send another +CMT or +CDS result code to TE until previous
one is acknowledged. If ME does not receive acknowledgment within required time (network time-out), ME sends
RP-ERROR to the network. TA shall automatically disable routing to TE by setting both <mt>and <ds>values

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

Notes
•
•
Each time an SMS or Cell Broadcast Message is received, the Ring Line goes Logic "1" for one second.
•
Requirements specific to Multiplex mode:
and <ds>on the other channels have to be set to zero. If either a SM or a Status Report is not acknowledged,
•
If the ME operates on different instances (MUX channels 1, 2, 3 or ASC0/ASC1) avoid different settings for
routing and indicating SMS. For example, if messages shall be routed directly to one instance of the TE (set
with AT+CNMI, AT^SSDA), it is not possible to activate the presentation of URCs with AT+CMERor AT+CNMI
on another instance. Any attempt to activate settings that conflict with existing settings on another interface,
will result in CME ERROR, or accordingly CMS ERROR.
•
Handling of Class 0 short messages:
If the host application is provided with a display and AT^SSDA=1 has been set Class 0 short messages can
be displayed immediately.
If the host application does not include a display, ME handles Class 0 short messages as though there was
no message class, i.e. it will ignore bits 0 and 1 in the <dcs>and normal rules for exceeded memory capacity
shall apply. This approach is compliant with GSM 03.38 .
•
•
If either a SM or a Status Report is not acknowledged, all AT+CNMIparameter in all channels will be set to
zero.

Notes
•
•
''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 user should be aware that the setting ''MT'' involves ''ME'' and ''SM'', with ''ME'' being filled up first. If the
''ME'' storage is full, TC63 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 indi-
cation of ^SMGO: 1. For more information regarding SIM and ME specific message classes refer to <dcs>
and the following specifications: GSM 03.38 and 3GPP TS23038.
•
•
•
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 dif-
ferences values for other instanes can result in not desired behaviours like different outputs for AT+CMGLand
so on.
While <mem3>equals ''SM'' and <mem1>equals ''ME'' it is possible that, after deleting short messages from
''ME'', the freed space on ''ME'' is reclaimed for new incoming short messages, when there is no space left on
the ''SM'' storage. As it is often the clients concern to have received short messages stored only to the SIM
card, inconsistent settings should be generally avoided. This can be achieved simply by using the same
parameter for all memory indices.

After invoking the write command wait for the prompt ">" and then start to write the message. To send the mes-
sage 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.

Command Description
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+CMGLis that the
status of the listed messages remains u n c h a n g e d (unread remains unread).

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

Incoming short messages with message class 1 (ME specific short messages) or class 2 (SM specific short

2" indication could occur, without issuing the indication "^SMGO: 1" before. The indication "^SMGO: 1" means
that both buffers (''ME'' and ''SM'') are full.

SIM related Commands
The AT commands described in this chapter are related to the Subscriber Identity Module (SIM) connected to
TC63.
Note:
If using data from the SIM please bear in mind that the content of all Elementary Files is subject to change at any
moment!
This is true because the network can change the SIM's data in the background via the SIM Application Toolkit
To get informed that changing Elementary Files has taken place the TA needs to hook to the SAT Proactive Com-
mand "REFRESH". To achieve this, the AT command interface of SAT, i.e. Remote-SAT, needs to be activated.
An overview is given at Chapter 16., SIM Application Toolkit (SAT) Commands, additional information is available

AT+CRSMoffers easy access of the Elementary Files on the SIM. Access to the SIM database is restricted to the
All parameters of AT+CRSMare used as specified by GSM 11.11 [23]. TC63 handles internally all required SIM
interface locking and file selection routines.
As response to the command, the TC63 sends the actual SIM information parameters and response data. Error
result code "+CME ERROR" may be returned if the command cannot be passed to the SIM, e.g. if the SIM is not
inserted. However, failure in the execution of the command in the SIM is reported in <sw1>and <sw2>param-

remote SIM is still possible.
Note
• <SimStatus>reflects the status of the SIM and the card holder tray. Therefore if an empty SIM card tray is
inserted, two URCs will be presented, indicating the status 1 followed by 0, i.e. a SIM is inserted into the card
holder tray but no SIM connection could be established.
If Remote SIM Access switches back from remote to local SIM, SCKS indicates the status 1 regardless of the
real SIM status. If no SIM is inserted this is followed by a second SCKS URC indicating 0.

Remote SIM Access (RSA) Commands
This chapter contains the reference of AT commands and responses related to the Remote SIM Access (RSA)
feature of the Cellular Engine TC63.
RSA allows the TC63 to use a SIM card via its serial interface additionally to the SIM which is locally attached
via the dedicated lines on the interface connector.
For further details contact the Wireless Modules Application Engineering Department at Siemens AG.
•
•
The TC63 is built in a car as part of and controlled by a Car Application, e.g. a telematic or telemetry system.
If a car driver enters his car he connects his cell phone with the Car Application. This can be done via a car
cradle or a wireless link.
Figure 15.1: Basic Remote SIM Access Usage Scenario
The necessary protocols and procedures are implemented following the «SIM Access Profile Interoperability
As stated there, with this profile the user can personalize his/her car-embedded phone with a SIM card in an
external device, which is connected via a wireless link. The external device can either be a simple SIM card
holder or a portable phone, which is brought into the car.
The SIM Access Profile builds on the interface between the telephone and a SIM card, refer to the «Specifi-
Since the TC63 itself does not control a Bluetooth wireless link, the SIM communication is routed via a serial
channel. It's up to an external application to map this data to any suitable communication path, e.g. a car cra-
dle or a Bluetooth modem as the SIEMOS Bluetooth-Module offered by Siemens AG.

In general, the ME can operate either as SAP server or as SAP client. A brief description of the configuration is
given below.
•
SAP Server
The SIM Access Server has direct (galvanic) access to a SIM. It acts as a SIM card reader, which assists the
client in accessing and controlling the SIM via the serial link. Typical examples of a server are SIM card reader
or cellular phones which are integrated in a car environment.
After SAP client activation (see (1) in Figure 15.2, SIM usage states of SAP server) the ME starts sending the
SAP message CONNECTION_REQ. However, the client will still use its local SIM card until a server
responds and the parameter negotiation with subsequent ATR access has been accomplished successfully.

•
SAP Client
The SIM Access Client is connected via a serial link to the SIM Access Server. The client accesses and con-
trols the SIM inside the Server via the serial link. Typical examples of a server are a simple SIM card holder
or a portable phone in the car environment. A typical example of a client is a car phone, which uses a SIM
card in the server for a connection to the cellular network. With the additional AT Commands it is possible to
switch the TC63 to use an external SIM instead of the physically attached (local) SIM during runtime.
After SAP server activation (see (1) in Figure 15.3, SIM usage states of SAP client) the ME waits for the SAP
message CONNECTION_REQ. The server will use its local SIM until the parameter negotiation has been
accomplished successfully.

SAP transparent binary format
SAP messages are transmitted as coded in the SAP specification. This data
format should be selected for transmitting SIM data to a Bluetooth stack which
is part of the application. The binary data will be exchanged transparently with
the ME. However, the SAP data format does not need ASCII character conver-
sation. As a result less data will be transferred and the SIM communication will
be faster.

Related AT Commands
The following commands might be of interest while using the RSA feature. For a detailed description of all com-
mands given below refer to:
• AT^SCKS
This AT command is used to check the current status of the SIM (local or remote).
• AT^SSET
After power on and personalization (PIN entry if required), the ME starts reading data from the SIM. Please
keep in mind that after entering the PIN, even after the TE sends "OK", subsequent commands need access
to data stored on the SIM may be blocked for up to 30 seconds. It may take even longer to access the remote
SIM depending on the establishment of the RSA communication link. Therefore, it is recommended that the
has been completed, be used. Afterwards all commands regarding to SIM data files can be used, e.g. the
SMS and phonebook commands.
• AT+CLCC
This command is recommended for querying the state of current calls. A list of all active calls will be returned.
This
is
especially
important
if
the
SAP connection
should
be
terminated
using
All calls or active GPRS contexts established via remote SIM will be terminated and the ME will use the locally
attached SIM card.
•
SIM data storage
It is recommended that all user relevant data are stored on the SIM only. For example, added phonebook and
SMS entries in the client's storage are not accessible after a RSA connection.
15.3.1 Establishing an RSA connection in a PC environment
To set up an RSA connection in a PC environment an appropriate PC application is needed. For test and eval-
uation purposes and as exemplary implementation guidance Siemens offers a PC application called "Com-
Bridge" as MS Windows executable and source code. For ordering details contact your local Siemens dealer or
visit the Siemens website. "ComBridge" provides basic features to generate a car application environment, e.g.
mapping of the SAP communication between a SAP server and client. To support the different RSA coding
modes (SAP and XSAP) and to transfer data between the two COM ports, the PC application uses two variable
modules (filters):
•
•
XSAP filter Translating the "^SRSM" URCs into AT command "AT^SRSM"
SAP filter Transparently transfer binary SAP messages. The generic "1:1" filter ("software null modem") can
also be used for this purpose, but communication might be slower since it performs bytewise data transfer.
15.3.2 Car cradle scenario (XSAP)
This example describes the connection of two cellular engines. It is recommended that the instructions be fol-
lowed in the order that they are presented:
•
•
Install two WinMux drivers on the PC and connect each ME to the physical port of a Multiplexer.
Connect the PC application "ComBridge" to one virtual COM port of each Multiplexer. This establishes an
communication link between the two cellular engines. Bear in mind that AT commands can still be issued on
both cellular engines using the remaining serial channels.
•
•
Select the "ComBridge" XSAP filter.
Open the XSAP "Config Filter" menu and deactivate the "Startup - Send Initialization" and the "Shutdown -
Switch back to local SIM" tags. However, the appropriate device IDs need to be entered in the "Startup"
frame.
•
•
•
Press the "ComBridge - start" button to connect both MEs.
Start the SAP client via AT command "AT^SRSA=2,2,3,0", if multiplexer channel 3 is used.
Start the SAP server via AT command "AT^SRSA=1,1,3,0", if multiplexer channel 3 is used.

15.3.3 Bluetooth scenario (SAP)
A connection between a cellular engine operating as a SAP client and an ME that supports Bluetooth and SIM
Access profile requires:
a) System requirements
•
•
Windows 2000, Windows XP (or later) installed
USB Bluetooth dongle. It is recommended to use the Fujitsu-Siemens product with the "PlugFree" Bluetooth
driver. This driver allows connections to Bluetooth profiles which are not yet specified by the SIG, e.g. SAP.
b) Installation procedure
•
After installing the USB Bluetooth dongle and the "PlugFree" driver software, the Bluetooth profiles are acces-
sible via their own virtual COM port.
•
If the WinMux driver has been installed another three virtual channels (mapped to additional COM ports) are
available. The physical Multiplexer COM port is connected to the cellular engine.
•
•
Start the Bluetooth connection using the driver provided by the USB Bluetooth dongle.
Through "ComBridge", one virtual COM port supplied by "WinMux" is connected to the SAP COM port of
"PlugFree". This establishes an direct communication link between the cellular engine and the cellular phone.
However, AT commands can still be entered to the cellular engine via the remaining multiplexer channels.
•
•
•
Select the "ComBridge" SAP filter.
Press the "ComBridge-Start" button to connect both MEs.
Start the SAP client using the AT command "AT^SRSA=2,2,3,1", if multiplexer channel 3 is used.

SIM Application Toolkit (SAT) Commands
This chapter offers a brief reference of commands and responses related to the TC63's SIM Application Toolkit
(SAT) implementation. Detailed information is available with the document "Remote-SAT User Guide" [4]. Please
contact the Wireless Modules Application Engineering Department at Siemens AG for details.
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 TC63 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 TC63's SAT from the SIM Application, such as "DISPLAY TEXT".
Envelope Commands are responded to the SIM Application from the TC63, such as "MENU SELECTION".

Command Description
The read command can be used to request the current operating status and the used alphabet of the Remote-
SAT interface.
The write command is used to activate the AT command interface of the SIM Application Toolkit in the TC63 and
needs to be issued after every power on. However, removing and inserting the SIM does not affect the activation
status.
SAT commands which are not using the AT interface (non MMI related SAT commands , e.g. PROVIDE LOCAL
INFORMATION) could be executed without activating Remote-SAT.

17. Phonebook Commands

17.
Phonebook Commands
The AT commands described in this chapter allow the external application to access the phonebooks located in
the TC63's memory or on the attached Subscriber Identity Module (SIM).
17.1
Sort Order for Phonebooks
Due to the support of UCS2 for the <text>part of phonebook entries, the sort order for phonebook records fol-
lows 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. Decomposi-
tion is not supported.
Phonebook entries whose namescontain 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.

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

18.16 AT^SNFTTY Signal TTY/CTM audio mode capability
TC63 offers basic support for equipment using the CTM standard (Cellular Text Telephone Modems). The benefit
of CTM is that text characters typed on a TTY device (Text Telephone Type-writer) can be transformed into spe-
cial audio burst signals for reliable transmission via the existing speech channels of a cellular phone system.
If CTM mode is activated, the ME will set the necessary bearer capability bit on outgoing (mobile originated) calls
and incoming calls with this bearer capability bit set are accepted. The TE needs to decode the special audio
burst signals.
If CTM mode is disabled, the ME will clear the bearer capability bit on mobile originated calls and incoming calls
with the bearer capability bit set are rejected because the TC63 expects that CTM coded speech data cannot be
decoded by the TE.
to be connected to one of the three audio interfaces of TC63. Traditional TTY devices that do not incorporate
CTM functionality can be connected through an external TTY-to-CTM adapter.

•
Before first using ring tones note that the following settings apply:
We have chosen to let you decide your own preferences when you start using ring tones. Therefore, factory
setting is AT^SRTC=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.
•
•
The test ringing signal cannot be activated while an MTC is ringing (ERROR).
If an MTC arrives during test playback, test ringing will be deactivated and "normal" ringing reactivated
(RING). Likewise, an MOC will also stop test ringing.
•
If no optional parameter is entered, the old value will be kept.

General functions:
The AT^SBCwrite command enables the presentation of URCs alerting the user of undervoltage and over-
voltage conditions before the module switches off. The automatic shutdown caused by undervoltage or over-
voltage 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. For further details regarding auto-

Functions available with battery connected:
The AT^SBCwrite command is important for entering the current consumption of the external application via
<current>. It should be noted that the charge control supported by TC63 works only if the requirements
described in the Hardware Interface Description [2] are met (battery type Lithium-Ion or Lithium Polymer,
presence of an NTC and protection circuit etc.) and if <current>is correctly specified. If the battery does
not incorporate an NTC, or the battery and the NTC are not compliant with the specified requirements the
battery cannot be detected by TC63.

The message will be reported, for example, when the user attempts to set up a call while the voltage is close

This URC will be reported when the voltage exceeds the maximum level specified in the Hardware Interface
In applications powered from Lithium batteries the incorporated protection circuit typically prevents over-
charging, 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 shut-

Enter the current consumption of your host application in mA (0...5000). This information enables TC63 to cor-
rectly determine the end of charging and terminate charging automatically when the battery is fully charged.
Note that if <current>is inaccurate, and the application draws a current higher than the final charge current,
either charging will not be terminated or the battery fails to reach its maximum voltage. Therefore, the termina-
tion condition is defined as: final charge current (50mA) plus current consumption of the external application. If
used, the current flowing over the VEXT pin of the application interface (typically 2.9V) must be added, too.
When the TC63 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 TC63.

AT^SSYNC Configure SYNC Pin
The AT^SSYNCcommand serves to configure the SYNC pin of the application interface. Please note that the
SYNC pin may be assigned different functions: Depending on the design of the host application, the pin can
either be used to indicate the current consumption in a transmit burst or to drive a status LED connected to the
pin as specified in [2]. For detailed information on the SYNC pin and its LED functionality refer to [2]. Before
changing the mode of the SYNC pin, carefully read the technical specifications.

SYNC mode:
Enables the SYNC pin to indicate growing power consumption during a trans-
mit 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.

19.7.2 Transmitting Data over AT Interface
This section provides information on the protocol used for data transmission to or from I²C devices and explains
the data mode. It is assumed that you are familiar with the I²C specification.
Throughout this section the following document conventions are used to mark the direction of send and receive:
Transfer Message: AT → I²C device driver
Response Message: AT ← I²C device driver
Channel Open / Close:
and return to command mode send the ASCII code # (0x23).
ASCII Protocol for I²C communication over AT interface:
The protocol allows using a Terminal program for the communication between the module and the I²C slave
device. To visualize transferred characters and response data it is recommended to run the Terminal program
in chat mode or to switch on local echo.
For transfer and response, special characters are defined, such as Start and Stop to mark a single message and
Close to disconnect the data channel. All valid special characters are listed below:

Message syntax:
Each Message consists of a Start and Stop character, a Message-ID, further protocol data and user data. The
notation of all elements is explained below:
Notation of Message-ID:
•
•
All ASCII characters between 0x00...0x7F. It is recommended to use only the characters 0...9, A...Z, a...z.
Length of the Message-ID: only one character
Notation of protocol data (except Message-ID) and user data:
•
•
•
•
•
Hex (0...9, a...f, A...F)
Without "0x" (0x01 →01)
Each hex value consists of 2 characters (1 →01)
Without delimiters such as comma, semicolon, space etc. (0xAE 0x01 0xA5 →AE01A5)
In a Transfer Message, the number of the I²C Slave Address and all subsequent written user data shall be
even. If it is odd, a protocol error will be reported. (Keep in mind that the number of all characters transmitted
between Start "<" and Stop ">" of the Transfer Frame shall always be odd because the ID is one character
only.)
•
Length of I²C Slave Address and user data: ≤ 2048 bytes
The first element of each message is the Start character ("<" for Transfer, "{" for the Response). Accordingly, the
last character of a message is the Stop character (">" for Transfer, "}" for the Response).
The second element of each message is the Message ID (1 character). The Message ID serves the user to dis-
tinguish between different messages. It is only relevant on protocol level (between AT interface and I²C device
driver), i.e. it is not sent to the I²C slave device.
Each transfer to the device is followed by a Response Message sent from the driver to the AT interface. The
response includes the Message ID and either OK ("+") or error characters ("-" or "!"). A successful response to
a Read Message contains the OK character and the read data. If an error occurs on the I²C bus, the response
consists of an error character followed by a 16 bit code specifying the faulty byte.
After each Transfer Message, wait for the Response Message before sending the next Transfer Message.
All characters entered outside a valid message (i.e. not input between Start character "<" and Stop character ">")
are ignored.

Table 19.4: Structure of Transfer and Response Messages on the I²C bus
Frame
Format
Write Transfer Message
< ID SlaveAddress Data >
Maximum length: 2048 bytes for I²C Slave Address
and written data. LSB of I²C Slave Address = "0".
Read Transfer Message

Read Length ≤ 2048 bytes. LSB I²C of Slave Address
= "1".
Response Message

On the I²C bus, read and write data are handled in two separate frames transmitted one after the other. This is
because the I²C bus has only two bus lines, I2CDAT for the serial data and I2CCLK for the serial clock. Write
data are packed into a Transfer Frame. Read data are packed into a Response Frame. The Transfer Frame con-
tains a Receive or Transmit Request (R/W Request) for the I²C master.

s
In a Transfer Message (Read or Write), the third element is the 7-bit I²C Slave Address (2 characters) that iden-
tifies each single device connected to the bus. The 8th bit of this byte is the LSB that determines the direction of
the message. If the LSB is "0" the master will write information to the selected slave. If the LSB is "1" the master
will read information sent from the slave.
In a Read Transfer Message on the I²C bus, the size of the expected data must be specified explicitly. This is an
element of 4 characters stating the number of bytes to be read. It must be placed after the I²C Slave Address.
19.7.3 Error Handling on the I²C Bus
Protocol error:
If a protocol error is detected the ASCII value "!" is sent to the AT interface. Also, a Stop Condition is sent to the
I²C device.
A protocol error occurs if
•
•
•
•
any data / address characters do not equal 0...9, a...f and A...F
the length of a read word is smaller or greater than 16 bits
the number of ASCII data is odd (e.g. "af1" instead of "af01")
the Read or Write request is greater than 2 KB (0x0800).
Acknowledge:
Once a transmission has completed successfully (Write or Read), the special character "+" (ACK) is included in
the Response sent to the AT interface.
During a Write Transfer, the I²C driver acknowledges each transferred byte, but the Response contains only one
ACK which is transmitted only if all bytes are successfully transferred. During a Read Transfer, an ACK is sent
when the I²C slave device notifies that it has recognized the I²C Slave Address.
Not Acknowledge:
During a Transmit Transfer, a NAK is given when the I²C Slave Device notifies a failure to receive either the I²C
Slave Address or a data byte. In this case, a Stop Condition is sent to the I²C device.
During a Receive Transfer, a NAK is transmitted only when the I²C does not receive any reponse for the I²C Slave
Address. The I²C device never acknowledges the validity of the received data (by sending an ACK the master
acknowledges each received byte to the slave).

19.7.4 Example: Using I²C Bus
As stated above, it is recommended to run the Terminal program in chat mode or to use the local echo. First,
activate the I²C interface:
AT^SSPI=0010,0000,0000
CONNECT
The first group of characters forms the <basicCon-
figuration>, where the first "0" sets I²C, the sec-
ond "0" is the internal port, the digit "1" sets 400 kbps
bit rate on the I²C bus, and the next "0" selects ASCII
coding. This is followed by a comma and the value
"0000" = no delay time after Write and Read.
Note: If omitted all above parameters are assumed
by
default.
Therefore,
instead
of
AT^SSPI=0010,0000,0000 it is sufficient to enter
only AT^SSPI=
The module is in data mode now. This allows you to send a Write Transfer Message:
<aAE000102030405060708090A0B0C0D0E0F>
Write Transfer Frame, where a = ID, AE = Slave
Address and write request.
{a+}
<bAF0010;>
Write Response Message, where a = ID.
Read Transfer Message, where b = ID, AF = Slave
Address and read request, 0010 = number of
expected bytes.
{b+000102030405060708090A0B0C0D0E0F}
Read Response Message, where b = ID.
To quit data mode and return to command mode enter the Close character "#":
#
OK
The response OK confirms that the ME is back to
command mode and ready to accept any AT com-
mands.
If the ME is in command mode, the response to the read command contains the factory settings.
AT^SSPI?
AT^SSPI=0,0010,0000,0000
The read command returns the connection state "not
connected" (Channel closed) and the factory set-
tings for I²C.
OK
If the ME is in data mode, the response to the read command contains the current settings.
AT^SSPI?
AT^SSPI=1,0010,0012,00FF
The read command returns the connection state
"connected" (Channel open) and the current settings
for I²C.

AT^SFDL Enter Firmware Download Mode
The AT^SFDL command allows the application manufacturer to download TC63 firmware into the module by
starting the download process from the host application or a customer-designed download program. The down-
load can be done over the serial interfaces ASC0 or ASC1 or the USB interface.
For this purpose, the TC63 firmware update file must be available in the format *.USF. The file can be requested
from Siemens. The firmware file consists of records to be transferred one by one from the host application to the
module.
This manual only describes the handling of the AT^SFDLcommand. All technical requirements and steps to pre-
pare the host application for this download solution can be found in the Application Note "Updating Firmware".
An example for developing an appropriate download program is included.
The AT^SFDLexecute command causes the module to reset and enter the firmware download mode (this may
take some milliseconds). After entering the download mode the module sends the start pattern HEX 0x01
("ANSWER_OK") to the application to indicate its ready state. Next, the application shall start to send the records
of the firmware file. Each record received on the module is acknowledged to the host application. Once all
records are successfully received, the module shuts down automatically.
If the module is switched on although it has no valid firmware installed, it waits 60s for the AT^SFDLcommand
(or for another download method to be started, such as WinSwup). If neither the AT^SFDLcommand nor equiv-
alent characters from another download method are received the module switches off after a 60s timeout.
If a valid firmware is still installed, but the AT^SFDLcommand is issued without sending any firmware afterwards
the module will stay in ready state. In this case it must be switched off.
