1.4 Document Conventions
Throughout this document EHS6 is also referred to as GSM/UMTS Mobile Engine or short ME, MS (Mobile Station) or Mobile Terminal (MT). In related documents the equivalent term DCE (Data Communication Equipment)
may be found.
AT commands are used to control the EHS6. The controlling device is referred to as Customer Application or
short TE. Related documents may use the equivalent term DTE (Data Terminal Equipment).
All abbreviations and acronyms used throughout this document are based on 3GPP specifications. For definitions please refer to 3GPP TR 21.905 [12].
1.4.1 Quick Reference Table
Each AT command description includes a table similar to the example shown below. The table is intended as a
quick reference to indicate the following functions:
PIN: Is the AT command PIN protected?
+ Yes
- No
± Usage is dependent on conditions specified for the command, or not all command types are PIN
protected (for example write command PIN protected, read command not).
Note: The table provided in Section 21.2, Available AT Commands and Dependency on SIM
PIN uses the same symbols.
+ Yes
- No
± In AIRPLANE mode, not all described functions are available. For example, the test or read com-

Page 19 of 513
1.5 AT Command Syntax
The "AT" or "at" prefix must be set at the beginning of each command line. To terminate a command line enter
<CR>. Commands are usually followed by a response that includes "<CR><LF><response><CR><LF>".
Throughout this document, only the responses are presented, <CR><LF> are omitted intentionally.
Table 1.4: Types of AT commands and responses
AT command type Syntax Function
Test command AT+CXXX=? The mobile equipment returns the list of parameters and value
ranges set with the corresponding Write command or by internal
processes.
Read command AT+CXXX? This command returns the currently set value of the parameter or
parameters.
Write command AT+CXXX=<...> This command sets user-definable parameter values.
Exec(ution) command AT+CXXX The execution command reads non-variable parameters deter-
mined by internal processes in the ME.
1.5.1 Using Parameters
• Multiple parameters are separated by commas. This applies to write commands, command responses, URCs
and result codes. Please note that throughout this document spaces behind commas may be added for better
readability.
• 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.
• 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 quotation marks.
• It is possible to omit the leading zeros of strings which represent numbers.
• If an optional parameter of a ITU-T V.250 command is omitted, its value is assumed to be 0.

1.5.2 Concatenating AT Commands
Concatenating AT commands on the same line is possible, though not recommended because of restrictions
listed below (for more details see ITU-T V.250 [16]).
When concatenating AT commands you need to enter the "AT" or "at" prefix only once at the beginning of a command line. Basic commands (i.e., ITU-T V.250 commands) are concatenated without delimiter. Extended commands (i.e., commands starting with AT+ or AT^) use a semicolon as delimiter.
Disadvantages and restrictions:
• There is no way to control the minimum time to wait between finishing an AT command and sending the next
one. Please refer to Section 1.6, Communication between Customer Application and EHS6 for details about
timing.
• The sequence of processing the AT commands may be different from the sequential order of command input.
• Many AT commands cannot be concatenated (see list below). Concatenating these commands might end up
with an error result code, or leads to an unexpected order of responses.

(prefix AT^S)
3GPP TS 27.005 commands (SMS) To be used standalone
Commands starting with AT& To be used standalone
AT+IPR To be used standalone
1.5.3 Application Design Considerations
When designing your application keep in mind that parameters given in AT command responses, result codes
and unsolicited result codes are only separated by commas with no spaces in between. Please take care that
your application ignores any additional spaces that may, nevertheless, be inserted in some AT command
responses, result codes and unsolicited result codes provided by EHS6.

1.6 Communication between Customer Application and EHS6
Page 21 of 513
1.6 Communication between Customer Application and EHS6
After power-up or restart ensure that the ME is in ready state before trying to send any AT command or data. For
detailed information on timing conditions, signal states and particularly the startup behavior of the EHS6's signal
lines refer to the Hardware Interface Description [2].
Leaving hardware flow control unconsidered the Customer Application (TE) is coupled with the EHS6 (ME) via
a receive and a transmit line.
Since both lines are driven by independent devices collisions may (and will) happen. For example, if the TE
issues an AT command and the EHS6 starts sending a URC. This will probably cause the TE to misinterpret 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 ms before sending
the next one. This applies to bit rates of 9600 bps or higher (see AT+IPR). At bit rates below 9600 bps the
delay must be longer: 300 ms at 1200 bps, and 500 ms at 300 bps.
The pause between two AT commands gives the EHS6 the opportunity to the transmission of pending URCs
and get necessary service.
• The TE shall communicate with the EHS6 using activated echo (ATE1), i.e. the EHS6 echoes characters
received from the TE.
Hence, when the TE receives the echo of the first character "A" of the AT command just sent by itself it has
control both over the receive and the transmit paths.
Using Backspace at command line:
• As the standard GSM alphabet does not provide a backspace functionality the EHS6 is designed to use the
character "08" (hex 0x08) as backspace for command line input. This allows the user to easily erase the last
character when writing an AT command. On the other hand, this solution requires entering the escape
sequence \08 for writing the "ò" character in GSM character string parameters.
• If command echo is enabled (ATE1) Backspace may cause 08 - 32 - 08 (decimal) character sequence or no
echo, depending on serial interface and speed of character input.

1.7 Supported character sets
Page 22 of 513
1.7 Supported character sets
EHS6 supports two character sets: GSM 7 bit, also referred to as GSM alphabet or SMS alphabet (3GPP TS
23.038 [35]) and UCS216 bit (ISO-10646 [13]). See AT+CSCS for information about selecting the character set.
Character tables can be found below.
Explanation of terms
• Escape Character
There are two types of escape sequences which lead to an alternative interpretation on subsequent characters by the ME:
- AT command interface
Escape sequences starting with character value 0x5C are used for the ME's non-UCS2 input and output.
- GSM 7 bit default alphabet
The escape sequence used within a text coded in the GSM 7 bit default alphabet is starting with character
value 0x1B and needs to be correctly interpreted by the TE, both for character input and output. To the
EHS6, an escape sequence appears like any other byte received or sent.
For SMS user data input after the prompt '>' in text mode (AT+CMGF)=1 and AT+CSCS="GSM" the character
0x1A is interpreted as 'CTRL-Z'. The character 0x1B (interpreted as 'ESC') as well as the escape character
0x5C (is interpreted as 'Ö'), therefore both escape mechanisms are not supported in this case.
• TE Character Set
The character set currently used by the Customer Application is selected with AT+CSCS. It is recommended
to select UCS2 setting.
• Data Coding Scheme (DCS)
DCS is part of a short message and is saved on the SIM. When writing a short message to the SIM in text
mode, the DCS stored with AT+CSMP is used and determines the coded character set.
• International Reference Alphabet (IRA)
The International Reference Alphabet is equivalent to ASCII (American Standard Code for Information Interchange) and ISO 646, i.e. it defines a 7-bit coded character set. The mapping can be obtained from the character set tables below (UCS2 values 0x0000 to 0x007F).
When you enter characters that are not valid characters of the supported alphabets the behavior is undefined.
If GSM alphabet is selected, all characters sent over the serial line (between TE and ME) must be in the range
from 0 to 127 (7 bit range).
Note: If the ME is configured for GSM alphabet, but the Customer Application (TE) uses ASCII, bear in mind that
some characters have different code values, such as the following:
• "@" character with GSM alphabet value 0 is not displayable by an ASCII terminal program, e.g. Microsoft©
Hyperterminal®.
• "@" character with GSM alphabet value 0 will terminate any C string! This is because value 0 is defined as C
string end tag. Therefore, the GSM Null character will cause problems on application level when using 'C'functions, e.g. "strlen()". Using an escape sequence as shown in the table below solves the problem. By the
way, this may be the reason why even network providers sometimes replace '@' with "@=*" in their SIM application.
• Some other characters of the GSM alphabet may be 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 in both
alphabets there are different characters assigned to value 7C (hexadecimal).
If the TE sends characters differently coded or undefined in ASCII or GSM (e.g. Ä, Ö, Ü) it is possible to use
escape sequences. The ME's input parser translates the escape sequence to the corresponding GSM character
value.
Note:
The ME also uses escape sequences for its non-UCS2 output: Quotation mark (") and the escape character itself
(\, respectively Ö in GSM alphabet) are converted, as well as all characters with a value below 32 (hexadecimal
0x20).
Hence, the input parser of the Customer Application needs to be able to translate escape sequences back to the
corresponding character of the currently used alphabet.
Unsupported characters are shown as a space (hexadecimal 0x20).

1.7.1 GSM alphabet tables and UCS2 character values
This section provides tables for the GSM default alphabet (3GPP TS 23.038 [35]) supported by the EHS6. Below
any GSM character find the corresponding two byte character value of the UCS2 alphabet. For details refer to
"ETSI GSM 03.38 mapping into Unicode" [14].
Figure 1.1: Main character table of GSM 7 bit default alphabet
1) This code is an escape to the following extension of the 7 bit default alphabet table.
2) This code is not a printable character and therefore not defined for the UCS2 alphabet. It shall be treated as the accom-
panying control character.

display a space until another extension table is defined.
2) This code represents the EURO currency symbol. The code value is the one used for the character 'e'. Therefore a 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
which does not understand the 7 bit default alphabet table extension mechanism will treat this character as Line Feed.

1.7.2 UCS2 and GSM character coding and conversion
This section provides basic information on how to handle input and output character conversion, e.g. for SMS
text mode, if the character representation of ME and Customer Application differ, i.e. if the Data Coding Scheme
and the TE character set use different mappings.
1.7.2.1 Output of SIM data (ME to TE)
Used character set DCS = 7 bit
GSM
GSM Case 1
GSM (1:1)
UCS2 Case 4
GSM to IRA (1:4)
Note: The ratio of SIM bytes to output bytes is given in parentheses.
Case 1
Every GSM character is sent to the TE as it is (8-bit value with highest bit set to zero).
Example: 47'H, 53'H, 4D'H 47'H, 53'H, 4D'H, displayed as "GSM"
Case 2
Every data byte is sent to the TE as 2 IRA characters each representing a halfbyte.
Example: B8'H (184 decimal) 42'H, 38'H, displayed as "B8"
Case 3
Every 16-bit UCS2 value is sent to the TE as 4 IRA characters.
Example: C4xA7'H (50343 decimal) 43'H, 34'H, 41'H, 37'H, displayed as "C4A7"
Problem: An odd number of bytes leads to an error because there are always two bytes needed for each USC2
character
Case 4
Every GSM character is sent to the TE as 4 IRA characters to show UCS2 in text mode.
Example: 41'H ("A") 30'H, 30'H, 34'H, 31'H, displayed as "0041"
Case 5
Every data byte is sent to the TE as IRA representation of UCS2 (similar to case 4).
Example: B2'H 30'H, 30'H, 42'H, 32'H, displayed as "00B2"
Case 6
Every 16-bit value is sent to the TE as IRA representation of it. It is assumed that number of bytes is even.
Example: C3x46'H 43'H, 33'H, 34'H, 36'H, displayed as "C346"
DCS = 8 bit

GSM
GSM Case 1
GSM (1:1)
UCS2 Case 4
UCS2 to GSM (4:1)
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 ME as GSM character (or ASCII with standard terminal emulation, e.g. Hyperterminal®).
Character value must be in range from 0 to 127 because of 7-bit GSM alphabet.
To reach maximum SMS text length of 160 characters in 140 bytes space characters will be compressed on SIM.
This must be set using the parameter <dcs> of AT+CSMP (add 64).
Example: "ABCDEFGH" typed is sent and stored uncompressed as 4142434445464748'H (stored compressed as 41E19058341E91'H)
Case 2
Every data byte is sent as 2 IRA characters.
Maximum text length is 280 IRA characters which will be converted into 140 bytes SMS binary user data
Example: "C8" typed is sent as 43'H, 38'H stored as C8'H
Case 3
Every 16-bit value is sent as 4 IRA characters.
Maximum text length is 280 IRA characters which will be 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 as 4 IRA characters representing one UCS2 character.
Example: To store text "ABC" using UCS2 character set you have to type "004100420043".
This is sent as 30'H,30'H,34'H,31'H, 30'H,30'H,34'H,32'H, 30'H,30'H,34'H,33'H detected as IRA representation of 3 UCS2 characters, converted to GSM character set and stored as 41'H, 42'H, 43'H.
Maximum input is 640 IRA characters representing 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"
This affects the maximum input length of a string)
Case 5
Every UCS2 character is sent as 4 IRA characters and is converted into two 8-bit values. This means that the
first two characters have to be '00'.
Example: UCS2 character 009F'H typed as "009F" is sent as 30'H,30'H,39'H,46'H converted into 8-bit value
9F'H.
Maximum number of UCS2 characters is 140 which are represented by 560 IRA characters. Number of IRA characters must be a multiple of four.
Case 6
Every UCS2 character is sent as 4 IRA characters each and is converted into a 16-bit value again.
Example: UCS2 character 9F3A'H typed as "9F3A" is sent as 39'H,46'H,33'H,41'H converted into 9F3A'H.
Maximum number of UCS2 characters is 70 which are represented by 280 IRA characters. Number of IRA characters must be a multiple of four.
Invalid UCS2 values must be prevented.
Error, value of UCS2 character > 7F'H
DCS = 8 bit

1.8 Unsolicited Result Code Presentation
1.8 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.
For most of these messages, the ME needs to be configured whether or not to send a URC. Descriptions of these
URCs are provided with the associated AT command. URCs which are not user definable are described in Section 1.8.1, Common URCs. A summary of all URCs can be found in Section 21.6, Summary of Unsolicited
Result Codes (URC).
Important: If the interface used for URC output is reserved by an active data connection or a long running AT
command, URCs are buffered internally and will be issued after the interface becomes idle again. A pending
URC will be signaled on the URC output interface via RING line. This allows to systematically suspend any longer
data connection (refer +++ and ATO) to check for pending URCs after being signaled!
For detailed information regarding configuration of URC signaling refer to AT^SCFG, "URC/Ringline", <urcRin-
glineCfg>.
Parameter Description
<info>
(num)
200 URC will be send 40 seconds after powerup when the JRC midlet was not tried
to start (no autostart, no midlet at all, whatever). Used to see in logs, that midlet
is not running, as example.
201 The JRC midlet was started, but did not succeed to full init itself within a (JRC
midlet defined) timeout. 5 seconds after this URC, the ME will restart.
202 The midlet was tried to start 5x, but was restarted (with ^SYSINFO: 201). Now,
the JRC midlet start was cancelled. No JRC midlet is running. A shutdown
timer of 10 minutes is started. After this timer, the ME will be switched off.
1.8.1 Common URCs
This section describes all URCs not associated to a certain AT command. They cannot be defined by the user
and appear automatically when the conditions described below occur.
Notes for "^SBC" URCs reporting undervoltage/overvoltage conditions:
Please refer to [2] for specifications regarding the minimum and maximum operating voltage limits. If the supply
voltage exceeds the defined thresholds the ME switches off automatically. The automatic shutdown procedure
is equivalent to the power-down initiated with the AT^SMSO command.
URC 1
^SYSLOADING
Indicates that the ME is in the process of starting up. Do not enter AT commands until the "^SYSSTART" URC
has shown up.
URC 2
^SYSSTART
Indicates that the ME has been restarted to Normal mode or Airplane mode and is ready to operate.
For Normal and Airplane mode see AT+CFUN.
Note: Autobaud mode (see AT+IPR) requires an "AT" or "at" string be given after restarting the ME. This
enables the ME to detect the bit rate set in the TE. After detecting the bit rate the ME will send the "^SYS-
START" URC.

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

Note: Autobaud mode (see AT+IPR) requires an "AT" or "at" string be given
after restart. This enables the ME to detect the bit rate set in the TE. After
detecting the bit rate the ME will send the "^SYSSTART" URC.

2.9 AT^SMSO Switch Off EHS6
AT^SMSO initiates EHS6's power-off procedure. Do not send any other AT command after this.
Low level of the ME's V180 signal and the URC "^SHUTDOWN" notify that the procedure has completed and the
ME has entered the POWER DOWN mode. Therefore, be sure not to disconnect the operating voltage until the
V180 signal has gone low and until the URC "^SHUTDOWN" is displayed. Otherwise, you run the risk of losing
data. For further details on how to turn off the ME refer to [2]. If a fast switch off (see parameter <fso> in
AT^SCFG) is enabled, there is no reply like OK, ERROR or any "^SHUTDOWN" URC.

^SHUTDOWN
Indicates that the power-off procedure is finished and the module will be switched off in less than 1 second.
If <fso> is used to enable a fast ME switch off, there will be no "^SHUTDOWN" URC.
Note
• If <fso> is used to enable a fast ME switch off, flash access cycles (writing/deleting) will be finalized, but there
will no longer be any network deregistration, the current settings will not be saved and there will be no further
output on the interfaces. All other jobs will be deleted and logical data consistance cannot be guaranteed.

Parameter Description
(str)
<al>
Audio Loop Setting
This parameter can be used to configure an audio loop for performing a simple verification of audio connections.
The feature is intended for testing only.
Neither a USIM nor a mobile network is necessary to turn the audio loop on. Audio mode can be selected via
AT command AT^SNFS. Audio path can be selected via AT command AT^SAIC.
In audio loop mode, don't try to change any audio settings (even though changes are accepted) such as interface, mode, volume etc. If you want to change these settings, do it before you turn on the audio loop.
(P)
“0“
“1“ Audio loop active
<acktimeout>
(str)
eCall ACK timeout in milliseconds
The ACK timer waits for receipt of two AL-ACKs after two LL-ACKs are received.
0...5000
(P)
...2147483646
No audio loop active
<callback>
(str)
eCall callback switch
Command switch that enables or disables the Inband modem for a mobile terminated voice call. The call is
accepted by ATA as usual. In this case the Inband modem always starts in PULL mode for the mobile terminated
call as opposed to PUSH mode if originating a call with AT+CECALL. In PULL mode the Inband modem remains
in listening state until PSAP calls for a data phase by sending START messages. The URC indicator flow is compatible to the flow during an originating call apart from the "+CIEV:ecallco,2" that appears on PSAP requests
only. If the user did not update the modem data the old MSD is taken during a data phase. While the eCall Inband
modem communication with the PSAP (e.g., transfer MSD) is in progress the voice channel is muted.
(P)
“0“
Disable Inband modem
“1“ Enable Inband modem on mobile terminated call

<callbacktimeout>
(str)(NV)
eCall callback timeout in milliseconds
This setting will take effect only after restarting the module.
Input values may be rounded down to the nearest second (e.g. input value "2999999" becomes "2999000" in
read command response.
(str)
(D)
...2147483646
0...43200000
<msd>
Minimum Set of Data for eCall
This parameter sets the Minimum Set of Data (MSD) for eCalls.
The data needs to be specified as hexadecimal encoded string, e.g. "1A13F3". The maximal length of the string
is 280 characters (140 bytes). If the content is shorter, the string will be padded with zeros. Powerup default is
a string of zeros.
<pullmode>
(str)
Command switch is required for ERA-GLONASS only. The switch restarts the ERA-GLONASS modem in PULL
mode, i.e., to re-establish the eCall without the usual startup phase for outgoing calls. This may be required if a
previous eCall was dropped after the MSD was transmitted successfully. The setting has to be done before the
eCall and will be set automatically back to default after the eCall is released.
(P)
“0“
Disable pull mode.
“1“ Enable pull mode.
<sessiontimeout>
(str)
eCall session timeout in milliseconds
The session timeout aborts the MSD transmission; the session timer starts when the eCall modem begins to
transmit (i.e., SF) and stops when the MSD is successfully transmitted (at least two LL-ACKs received).
0...20000
<starttimeout>
(P)
...2147483646
(str)
eCall start timeout in milliseconds
The start timer awaits start signal; it starts when the eCall emergency setup is executed and stops when three
valid, consecutive SF and start messages are received.
0...5000
<ecc>
(P)
...2147483646
(str)(+CSCS)(NV)
Emergency call numbers on non-ECC USIM
This parameter specifies emergency call numbers on USIM without ECC field and with empty ECC field. The
parameter has no influence on the commonly used emergency numbers 112 and 911 which are always supported.
Please refer also to Section 7.2, ATD where you can find a list of emergency call numbers supported if no USIM
is inserted.
The value range of <ecc> is "0"..."255". To select or deselect an emergency number calculate the sum of the
values of all desired numbers and use the resulting value. For example, for "08" (2) and "118" (8) please enter
the value (10).
Parameter is global for the ME, non-volatile and will not be reset by AT&F.
(D)
“ 0“

<dormancy>
(str)(NV)
Dormancy Mode
This parameter controls the Dormancy Mode.
Parameter is global for all interfaces, non-volatile and will not be reset by AT&F.
Changed setting will take effect only after restarting the module.
(D)
“0“
Disable Dormancy Mode, i.e., the ME behaves as requested by the used
USIM.
“1“ Enable Dormancy Mode.
<eCallUSIM>
(str)
eCall USIM
This parameter provides the information if an eCall-Only-USIM ("eUSIM") is used.
“0“ eCall-Only-USIM not detected.
“1“ eCall-Only-USIM detected .
The user defined settings of Dormancy Mode are overruled by an eCall-Only-USIM. If Dormancy Mode is activated by the user, the ME behaves identical to the functionality as requested by an eCall-Only-USIM, meaning
the ME will camp on the network in "eCall-Inactive-State" (see 3GPP TS 24.008) and will only register to a network for eCall execution.
If Dormancy Mode is activated (or an eCall-Only-USIM is used) when the eCall Callback Timer (see parameter
<callbacktimeout>) expires (indicated by URC "+CIEV"="ecaller,5"), the module deregisters automatically
from the network and returns to camping on the PLMN in the "eCall-Inactive-State".
(str)(NV)
<scc>
Speech Codec
Speech Codec Configuration for voice calls
This parameter can be used to configure the speech version indications in the bearer capabilities in case of voice
calls (see 3GPP TS 24.008). If you change this parameter the command returns "OK", a new setting takes effect
the next time the UE is restarted (after power-cycle). Parameter is global for all interfaces, non-volatile and will
not be reset by AT&F.
(D)
“0“
All supported speech codecs are enabled for voice calls.
“1“ The speech codecs GSM HR, GSM HR AMR and GSM AMR are disabled for
voice calls.
<g_mode>
(str)(+CSCS)(NV)
Mode of operation for signal lines
This parameter can be used to configure shared signal lines of the EHS6 module. Depending on the connected
devices the setting determines the specific function assigned to the related signal line(s). Keep in mind that the
functions assigned to shared lines are mutually exclusive. When a line is reserved for one interface, then the
<g_mode> parameter is automatically set to 'rsv' for all other interfaces that use this line.
For example, to enable the SPI interface select AT^SCFG="GPIO/mode/SPI","std". This will automatically set
AT^SCFG="GPIO/mode/DSR0","rsv" for DSR0 used as SPI_CLK line for SPI and AT^SCFG= "GPIO/mode/
ASC1","rsv" for ASC1 (ASC1 lines used as SPI lines). At the same time this will lock the GPIO functionality of
GPIO3, GPIO16, GPIO17, GPIO19.
To enable the DAI interface select AT^SCFG="GPIO/mode/DAI","std". This will lock the GPIO functionality of

Initial Retransmission Timeout (IRT)
(D)
1...3
...60 This parameter determines the time (in seconds) the TCP/IP stack will wait
before starting the first retransmission of packets during the initial connection
establishment phase.
The TCP protocol ensures the retransmission of packets several times at
increasing intervals until some upper limit is reached.
This mechanism prevents packet loss and serious congestion problems. In
addition, the parameters <tcpMr> and <tcpOt> can be set to further optimize
this mechanism for special conditions depending on the mobile network.
Parameter is global for the ME and non-volatile. Use of default value is recommended. If changed the new value takes effect the next time you

...30 This parameter determines the maximum number of times to retransmit TCP
packets.
The value set with <tcpMr> will be assumed as default for the <srvParm-
Tag> "tcpMR" when a new service profile is created with AT^SISS. In each
service profile, you can set another "tcpMR" value which has precedence over
the global value set with AT^SCFG. Existing service profiles are not affected
when you change the global value via AT^SCFG.
Parameter is global for the ME and non-volatile. Use of default value is recommended.
<tcpOt>
(str)(+CSCS)
Overall TCP Timer for outstanding connections (tcpOT)
1...6000
(D)
This parameter specifies the number of seconds to wait before closing a connection if TCP/IP packets are not acknowledged.
Setting the maximum value is practically equivalent to deactivating the tcpOT
mechanism because the maximum time would never be reached by the TCP/
IP stack.
The value set with <tcpOt> will be assumed as default for the <srvParm-
Tag> "tcpOT" when a new service profile is created with AT^SISS. However,
in each service profile, you can set another "tcpOT" value which has precedence over the global value set with AT^SCFG. Existing service profiles are not
affected when you change the global value via AT^SCFG.
Parameter is non-volatile. Use of default value is recommended.

This parameter enables a trace output of the Over The Air procedure. The tracer is useful for obtaining additional
information when setting up an OTAP scenario. The output is provided on the interface configured with <uwDe-
vice> (given <uwDevice> has to differ from currently used one) or if omitted (for compatibility reason only) on
the interface on which the command was entered. While the tracer is enabled the interface is used for trace output only, meaning that no AT commands can be entered. The tracer will be switched off only by a reset of the
ME, e.g. after a completed OTAP procedure or if disabled by setting parameter to "0".
“0“ Disable OTAP tracer.

<deviceDescr>
(str)(+CSCS)(NV)
Device Descriptor
This parameter determines whether to use the ME's standard USB Device Descriptor configuration (default) or
a Device Descriptor configuration customized by the Customer Application manufacturer.
Parameter is global, stored non-volatile in ME and not reset by AT&F. Setting takes effect after next USB interface enumeration.
(D)
“0“
Standard USB Device Descriptor of the ME.
If <deviceDescr>=0 is set all other parameters related to "Serial/USB/DDD"
cannot be changed. For use in a Windows environment, the "usbmodem.inf"
file delivered with EHS6 shall be present.
Note that whenever the EHS6 firmware is updated over the USB interface the
ME's standard configuration must be present. Therefore, before starting a
EHS6 firmware download be sure that <deviceDescr>=0 is activated and,
under Windows, the ME's "usbmodem.inf" file can be found. Remember to
restart the ME after reverting to <deviceDescr>=0 and before starting the
firmware download.
“1“ Customer specific USB Device Descriptor.
If <deviceDescr>=1 is set all other parameters related to "Serial/USB/DDD"
can be changed.
Customizing the USB Device Descriptor configuration requires a unique Vendor ID obtained from the USB Implementers Forum. For information please
refer to http://www.usb.org.
For use under Windows a customized INF file for the USB modem must be
present. An easy way to create this file is copying the ME's "usbmodem.inf" file
and overwriting the equivalent values changed with AT^SCFG, usually at least
the Vendor ID, Product ID and, optionally, the manufacturer string. This is
because the strings given for the customized "Serial/USB/DDD" parameters
must be identical with those contained in the INF file.

<serialNo>
(str)(+CSCS)(NV)
Device's serial number
Optional serial number. Empty string if not used, like in the case of the ME'S standard USB Device Descriptor
configuration.
A serial number has several advantages. For example, it enables the host to assign the same virtual COM port
to same USB device even though the device is connected to another USB port. This eliminates the need for the
host to load the driver again.
Parameter is global, stored non-volatile in ME and not reset by AT&F. Setting takes effect after next USB interface enumeration. If parameter <serialNo> is not specified, the default value of ME's standard USB Device
Descriptor applies.

“USB4“ Output of "System.out" is routed to the Universal Serial Bus interface 4.
“USB5“ Output of "System.out" is routed to the Universal Serial Bus interface 5.
“UDP“ Output of "System.out" is routed to a UDP socket. The parameter requires that
the port number be given with <intvalue>.
"UDP" is intended only for use with the Userware IDE and will be set automatically each time you start the debugging emulator of the EHS6 (on-device
debugging). Closing the debugger causes the ME to reboot and automatically
resets the <uwDevice> value last selected. This eliminates any need for manually setting "UDP" with AT^SCFG, and, besides, allows you to select another
"System.out" target to be used when not debugging. Due to this, the value
"UDP" is volatile unlike all other <uwDevice> values, and switching to "UDP"
is not supported while Userware is running.
“FILE“ Output of "System.out" is written into a file. Requires additional parameters
<intvalue>, <filename> and <logmode>. Because excessive writing to
the ME's flash file system decreases the life time of the flash memory, it is recommended to use the "FILE" device only during development phases.
“SYSTEM“ For internal use only.
<intvalue>

If <uwDevice>= "FILE": Size of the log file in bytes, values less than 1024 are
not supported.
<filename>
(str)(+CSCS)
This parameter is required only if parameter <uwDevice> for the Userware "System.out" is set to "FILE". It
specifies the absolute path and the file name of the log. The local Flash File system is identified by: "A:", directory
separator is "/" (002Fh).
The underline character "_" (005Fh) is not supported.
The log is split into two concatenated files, each using half of the entire log size set with parameter
<intvalue>. Each file name consists of the name specified with parameter <filename> and the numeric
extension "0" or "1" automatically appended, for example "a:/java/log.txt.0" for the first part of the log and "a:/
java/log.txt.1" for the second part. When the first log file reaches half of the log size, the "System.out" is written
to the second file. When the second file is used up, the ME starts to overwrite the first one.
Parameter is global, stored non-volatile in ME and not reset by AT&F.
Parameter length: maximum 125 characters.
<logmode>

“on“ Stdout strings are never truncated. If output device buffer is full, the Java VM
is waiting until memory becomes free again. This handling may slow down the
VM when a lot of outputs are created, even a full stop of the VM is possible, if
the used device is in flow control. Please use this option very carefully, and
never in a production environment.

<wd>
Watchdog configuration and control
This parameter is used to configure the watchdog behavior.
The action triggered by the watchdog takes place without regard of network registration, file system operation
and other ongoing actions (hard reset).
Parameter is global for all interfaces, non-volatile and will not be reset by AT&F.
(D)
“0“
Watchdog "do nothing". The watchdog has no effect.
“1“ Watchdog "re-start". The watchdog will reboot the system.
“2“ Watchdog "shutdown". The watchdog will switch off the system.
<PL_mode>
(str)
Power Limitation Mode
The AT^SCFG subcommand "Radio/Mtpl" can be used to instantly adapt the module's Specific Absorption Rate
(SAR) by reducing its output power for specific or all bands in any operating mode.
8 profiles for instant RF output power limitation can be defined and stored to the NV memory. A profile contains
all supported bands ( <rba>) and, for each single band, a parameter limiting the maximum RF output power
(<PL_limit>). For GSM, a second parameter, <PL_limit8psk>, is required to set the RF output power limit
for GSM 8 PSK. The RF output power limit for a GSM band is related to one transmit timeslot. If two/three/four
timeslots are used for transmission the specified power limit is reduced by another 3 / 4.8 / 6 dB.
Changing limit values of a profile with <PL_mode> 3 takes effect after ME restart only. Activating and deactivating power limitation with <PL_mode> 1 or 0, takes effect instantly. The <PL_mode> is volatile, therefore output
power limitaton is deactivated after ME restart.
For an example on how to configure and trigger instant power limitation see below Example section.
(P)
“0“
Power limitation deactivated (no further parameters are possible).
“1“ Power limitation activated.
<PL_profile> parameter is mandatory for activation.
“2“ Query profile settings.
The response shows the currently used limit values if instant power limitation
is active, i.e. if <PL_mode>= 1. Therefore, bear in mind that modified profile
values will be visible only if you restart the ME and run a query before activating
instant power limitation.
You can read either all profiles, or a specific profile by adding a
<PL_profile> number.
“3“ Change profile. All parameters are mandatory. Remember to restart the ME
after changing the output power limits of a profile.
<PL_profile>

2.13 AT^SPOW
2.13 AT^SPOW Set UART Mode and SLEEP Mode on UART
AT^SPOW enables or disables the ME's UART interfaces ASC0 and ASC1 and controls SLEEP mode on both
interfaces. Parameter settings are non-volatile and common for all interfaces, but are not effective for USB.
If SLEEP mode is enabled (<mode>=2), CTS0 and CTS1 are periodically activated for the time set with <awake>
enabling the ME to listen to paging messages from the base station. The AT interface is enabled during the active
periods of CTS0/CTS1.
The inactive periods of CTS0/CTS1 (when power saving is effective) depend on the paging cycle of the base
station and may vary between 0.47 - 2.12 seconds in GSM networks and 0.64 - 5.12 seconds in UMTS networks.
This means that the TE should provide an equivalent timeout for trying to access the AT command interface.
SLEEP mode requires that CTS/RTS flow control be configured both on ME side (see AT\Q) and TE side.
If SLEEP mode is enabled on ASC0 and ASC1, keep in mind that the module's current consumption decreases
only if USB is either disconnected at all, or in Suspend state with VUSB_IN line enabled.
Please refer to "EHS6 Hardware Interface Description, Version 03.001" for more information on power saving.

Parameter Description
<indDescr>
This section describes <indDescr> values and their associated <indValue> ranges.
For command input on the AT^SIND write command line <indDescr> values are handled as string type. In
responses and URCs <indDescr> values are output without quotation marks.
“service“ Service availability:

“rssi“ Received signal (field) strength:
0 Signal strength -112 dBm
1 - 4 Signal strength in 15 dB steps
5 Signal strength -51 dBm
99 Signal strength not known or not detectable
Received signal (field) strength can also be obtained with AT+CSQ. However,
the signal strength is scaled to value range 0..31 by this command.
“simdata“ USIM notifies of changed Elementary File data:
All data provided by the USIM is stored in one of many of its so-called Elemen-
tary Files.
Be aware that this Elementary File data can be changed at any time by the net-
work provider or an application running on the USIM.
Therefore, a "+CIEV: "simdata"" URC is issued if USIM sent a SAT REFRESH
command indicating that the content of one or more Elementary Files has been
changed.
“vmwait“ Message Waiting Indication. Indicates new message(s) waiting included in
User Data Header (UDH).
0 Value 0 notifies that no new voice, fax, mail, or other message is avail-
able, and is provided by the service center to clear the message indication after the subscriber has retrieved all messages.
1 Value 1 notifies the subscriber that the mailbox contains one or several
messages.
"vmwait" indicates the receipt of a special short message with a Message Waiting Indicator. The service must be provisioned by the operator.
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 message is put into the mailbox. After the
subscriber has retrieved all messages the service center automatically sends
another message indication which provides the value 0.
Some operators may also send the number of waiting voice messages along
with the indication. In this case, the number will be displayed by the EHS6 as
part of the URC. For example:
"+CIEV: vmwait,1,3,0,0,0" notifies that three new voice messages are waiting.
"+CIEV: vmwait,1,5,2,3,1" notifies that five new voice messages, two fax messages, three email messages and 1 other message are waiting.
However, it should be noted that neither the read command AT^SIND? nor the
write command AT^SIND=<mode>,2 display the number of waiting messages.
The "vmwait" indicators do not apply if a network provider signals new voice
mail(s), mail(s), fax or others via standard SMS. In this case the indicator "mes-
sage" will be displayed.
“ciphcall“ Ciphering Status Change Indication:
0 Current call or SMS is not ciphered.
1 Current call or SMS is ciphered.
As stated in GSM specifications 02.07 and 02.09 the ciphering indicator feature
allows the EHS6 to detect that ciphering is not switched on and to indicate this
to the user.
The URCs +CIEV: ciphcall,0 or +CIEV: ciphcall,1 will show up when:
- a call is etablished,
- ciphering status changes during a call,
- an SMS is sent or received.
The URC will not be printed when the connection is released.
Read command AT^SIND? returns valid ciphering status only if a call is in
progress or active.
URC with ciphering status change indication appears only the interface on
which URC indication was enabled using AT^SIND.

“eons“ Enhanced Operator Name String (EONS) Indication:
The Enhanced Operator Name String indicator feature allows the EHS6 to output various operator names for different PLMN identities via URC. It also allows
the output of a different operator name based on a subset of the registered network by using a range of Location Area Codes (LACs) or a single LAC.
The presentation of the "eons" indicator is determined by network activity. For
example, the indicator appears every time a location update occurs or a NITZ
information is sent, no matter whether or not the status of the EONS information has changed. This means that the same EONS information may be
reported several times.
The EONS tables are stored in the USIM and will be read at power-up.
Following are the USIM Elementary Files that are affected by the introduction
of EONS feature in the USIM:
EF
(USIM Service Table) - describes which features are active.
SST
EF
(Operator PLMN List) - contains the PLMN identification and location ID
OPL
together with the index of the corresponding PNN record
EF
(PLMN Network Name) - contains the full and short form version of the
PNN
network name for the registered PLMN
If the Operator Name Source is CPHS Operator Name String long and short
form, refer to <indValue>, the following two USIM Elementary Files will be
used:
EF
who issued the USIM.
EF
the PLMN operator who issued the USIM.
“nitz“ Network Identity and Time Zone indication:
This indicator shows the time relevant information elements of an MM Information (MMI) or GMM Information (GMMI) message received from the network
(see 3GPP TS 24.008 [40], ch. 9.2.15a and 9.4.19). The network usually sends
a NITZ indicator when the mobile attaches to the network, when it enters a
location area with different time zone or when a daylight change occurs.
A NITZ indicator may consist of the following parameters: Universal Time (UT),
local Time Zone (TZ), Daylight Saving Time (DST). All information elements of
MMI/GMMI are optional and therefore, the presentation of the parameters
<nitzUT>, <nitzTZ>, <nitzDST> varies with the network. For example, the
network may send all three parameters UT, TZ, DST, or only UT and TZ or only
TZ.
UT is indicated in usual date/time format and represents the current world time
(GMT) at the moment when sent.
TZ is given as a positive (east) or negative (west) offset from UT in units of 15
minutes.
DST shows the number of hours added to the local TZ because of daylight saving time (summertime) adjustment. Usually DST is 1 hour but it can be also 2
hours in certain locations.
Example for time and time zone with DST:
+CIEV: nitz,"04/07/23,13:39:20",-28,1
In this example TZ is -28, showing a time offset of -7 hours (west) to Universal
Time/GMT (which never changes for DST). DST is 1 which indicates that one
hour was added to TZ because of Daylight Saving Time. If a network does not
send the DST parameter the TZ value would be -32 (8 hours west) as would
be done in winter:
+CIEV: nitz,"04/11/23,13:39:20",-32
Please be aware that although the last NITZ value can be looked up again via
"AT^SIND=nitz,2" the returned values may be out of date. Especially the UT
value is obsolete because there is no internal NITZ clock and therefore no continuation of UT.
(Operator Name String) - contains the name of the PLMN operator
ONString
(Operator Name Short form) - contains a short form of the name of

NITZ values are lost when the ME detaches from network. Also when a manual
network selection fails and the ME automatically falls back to the previous network the NITZ values cannot be recalled. Nevertheless an indicated time zone
“psinfo“ Packet Switched Status Indication
“lsta“ Link Stability Indication (for 2G)
is valid until a new MMI/GMMI will trigger another NITZ indication.
"psinfo" indicates the status of the ME related to packet switched data calls.
Please consider that some providers don't support the indication of HSDPA/
HSUPA.
0 GPRS/EGPRS not available in currently used cell
1 GPRS available in currently used cell

The Link Stability indicator feature allows the EHS6 to output radio link errors
and statistic parameters of signal strength distribution across the band via
URC.
0 Radio link error.
1 Radio link signal strength distribution.
2 Radio link error during voice call.
The presentation of the "lsta" indicator is determined by the radio link spectrum
shape. For example, each time a radio link error appears the URC indicates an
Error Downcounter value and the RSSI of the serving cell to provide some kind
of warning. Every consecutive error decrements the Error Downcounter value
and successful downlink signal reception resets it to start value of 11. The factor on which Error Downcounter is decremented depends on network settings.
Error Downcounter value 0 means that the ME has lost the cell and will start
the cell reselection process. In this case the URC is enhanced and includes the
following statistic parameters of signal strength distribution across the band.
These are:
- Number of reported channels,
- Maximal signal strength value,
- Minimal signal strength value,
- Mean value of signal strength across frequency band and
- Variance of signal strength across frequency band.
To avoid that radio link error URCs are output too often, when radio conditions
are bad, you can select a lower warning level with <lstaLevel>.
Link Stability Indication (for 3G)
URC's are issued for radio link quality and statistic parameters of signal
strength distribution across the band.
10 Radio link quality.
11 Radio link signal strength distribution.
In idle mode S-Criteria of serving cell is evaluated each DRX (Discontinuous
Reception) Cycle (64, 128, 256 or 512 frames).
If S-criteria is not met, Cell Reselection Evaluation Process is executed.
If the EHS6 has not found any new suitable cell based on searches and measurements of the neighbor cells indicated in the measurement control system
information for 12 seconds, the EHS6 initiates cell selection procedures for the
selected PLMN.
A DRX counter counts the consecutive DRX cycles that serving cell does not
meet S-criteria during that 12 seconds. This is used for the URCs with <ind-
Value> equals "10".

“dtmf“ DTMF decoder.
AT^SIND "dtmf" can be used to configure a DTMF decoder capable of listening
to remote downlink or local microphone samples. The decoder can be enabled/
disabled on the fly, even within an ongoing call. Detecting DTMF signals from
the local side is supported even in absence of a call.
The detected DTMF characters are buffered.
If enabled with parameter <mode>=1, the buffered DTMF characters are
shown as "dtmf" URC when the DTMF buffer is emptied. The DTMF buffer is
emptied either when full (max. 15 DTMF characters) or when the timeout specified with <dtmfBufferTimeout> expires.
Parameter <dtmfSrc> specifies whether to detect DTMF tones sent from a
local source or via the network.
Parameter <dtmfSilenceTime> specifies the minimum silence time after
which the ME is ready to detect the next valid DTMF character. The benefit of
this parameter is to optimize the robustness of DTMF decoding versus data
throughput.
Parameter <dtmfMinToneTime> specifies the minimum duration of a tone
that can be detected as a DTMF character. All tones shorter than the value
specified by this parameter will be ignored.
For use after restart, the presentation <mode> for this indicator can be stored
to the user profile with AT&W. The same applies to <dtmfSrc> and to the time
parameters (see below). AT&F restores the delivery defaults.
Example for a DTMF character train with 4 characters:
+CIEV: dtmf,"1*2#"
Example for a DTMF character train with the maximum of 15 characters:
+CIEV: dtmf,"004930311021A2B"
