Introduction  
Definitions  
The words “Mobile Station” (MS) or “Mobile Equipment” (ME) are used for mobile terminals that  
support GSM services. Terminal Equipment (TE) is the Human Machine Interface (HMI) of a  
GSM device (modem or handset). TE can be a handset HMI or the AT command line interface.

ME  
A call from a GSM mobile station to the PSTN is called a “mobile originated call” (MOC) or  
“outgoing call,” and a call from a fixed network to a GSM mobile station is called a “mobile  
terminated call” (MTC) or “incoming call.”  
Presentation Rules  
In the remainder of this document, AT commands are presented in three parts. A “Description”  
paragraph provides general information about the AT command (or response) behavior. A  
“Syntax” paragraph describes how to use the command, and gives possible responses in a readable  
format. A “Defined values” paragraph provides parameter values, and the AT command for the  
corresponding responses. Schemas are provided where necessary.

AT Command Features  
This chapter includes information about the AT Command Features of the OnCell G2150I. The  
following topics are covered in this chapter:  
 
 
OnCell G2150I AT Command Set  
AT Command Features  
Serial Line Settings  
A serial link handler is configured with the following default values (factory settings):  
y 115200 bps  
y 8 data bits  
y 1 stop bit  
y no parity  
y RTS/CTS flow control  
Use the +IPR, +IFC, and +ICF commands to change these settings.  
Command Line  
Commands always start with AT (which means ATtention) and finish with a <CR> character.  
Information Response and Result Codes  
Responses start and end with <CR><LF> (except for the ATV0 DCE response format) and the  
ATQ1 (result code suppression) commands.  
y If the command syntax is incorrect, the “ERROR” string is returned.  
y If the command syntax is correct, but the command is transmitted with the wrong parameters,  
the +CME ERROR: <Err> or +CMS ERROR: <SmsErr> strings are returned with adequate  
error codes if CMEE was previously set to 1. By default, CMEE is set to 0, and the error  
message is only “ERROR.”  
y If the command line has been executed successfully, an “OK” string is returned.  
In some cases, such as “AT+CPIN?” or (unsolicited) incoming events, the product does not return  
the “OK” string as a response.  
In the following examples <CR> and <CR><LF> are omitted intentionally.

Defined values: No parameter  
Power Off: +CPOF  
Description: This specific command stops the GSM software stack as well as the hardware layer,  
or the G2150I activity. The AT+CFUN=0 command is equivalent to +CPOF.  
Command syntax: Command syntax: AT+CPOF[=1]  
Command  
Possible responses  
AT+CPOF  
OK  
Note: Stop GSM stack  
Note: Command valid  
AT+CPOF=1  
OK  
Note: Stop the Wireless CPU  
Note: Command valid  
Note: After AT+CPOF=1, the G2150I will not respond to AT commands. To reset it, use the hard  
reset.  
Note: In autobaud mode, after an AT+CPOF, unsolicited information waking up the G2150I is  
sent at 9600 bps until an AT command is sent. When an AT command is sent, the G2150I will  
synchronize with the sender’s speed. (see CAUTION in § 14.1.1)  
Defined values: No parameter  
Set Phone Functionality: +CFUN  
Description: This command selects the mobile station’s level of functionality. When the  
application wants to stop the product with a power off, or if the application wants to force the  
product to execute an IMSI DETACH procedure, then it must send: AT+CFUN=0 (equivalent to  
3-5  
 
 
OnCell G2150I AT Command Set  
General Commands  
AT+CPOF). This command executes an IMSI DETACH and makes a backup copy of some  
internal parameters in SIM and in EEPROM. The SIM card cannot then be accessed. If the mobile  
equipment is not powered off by the application after this command has been sent, a re-start  
command (AT+CFUN=1) will have to issued to restart the whole GSM registration process. If the  
mobile equipment is turned off after this command, then a power on will automatically restart the  
whole GSM process. The AT+CFUN=1 command restarts the entire GSM stack and GSM  
functionality: a complete software reset is performed. All parameters are reset to their previous  
values if AT&W was not used. If you write entries in the phonebook (+CPBW) and then reset the  
product directly (AT+CFUN=1, with no previous AT+CFUN=0 command), some entries may not  
be written (the SIM task does not have enough time to write entries in the SIM card). In addition,  
the OK response will be sent at the last saved (AT&W) baud rate defined by the +IPR command.  
With the autobauding mode the response can be at a different baud rate. It is therefore preferable  
to save the defined baud rate with AT&W before directly sending the AT+CFUN=1 command.

Note: Seconds are taken into account.  
<index> offset in the alarm list, range 1 to 16.  
Generic SIM Access: +CSIM  
Description: This command allows direct control of the SIM by a distant application on the TE.  
The <command> is sent without any modification to the SIM. In the same manner the SIM  
<response> is sent back by the ME as it is. The user shall then take care of processing SIM  
information within the frame specified by GSM as specified in GSM 11.11(or 3GPP TS  
51.011). If operation mode is not allowed by the ME, +CME ERROR: <error> is returned.  
Between two successive +CSIM commands, there is no locking of the interface between the SIM  
and the GSM application. Since in this situation some command types and parameters can modify  
the wrong SIM files, some operations, described below, are not allowed for CSIM command.  
However, it is possible to process them with the CRSM command.  
Command syntax: AT+CSIM=<length>,<command>

AT+CSIM=?  
Defined values: <length>: integer type  
Length of the characters that are sent to TE in <command> or <response> (two times the actual  
length of the command or response). For command sent to TE, This value must be in the range  
[10 – 522], or a CME_ERROR=3 is returned.  
<command>: hexadecimal type  
Command passed on by the MT to the SIM in the format as described in GSM 11.11 (or 3GPP TS  
51.011) (hexadecimal character format; refer +CSCS)  
Second Byte Value not supported:  
Due to the absence of locking, a CME_ERROR=3 is returned for the following  
instructions ( See CRSM commands):  
• D6: UPDATE BINARY  
• DC: UPDATE RECORD  
• 32: INCREASE  
• 44: REHABILITATE  
• 04: INVALIDATE  
• 88: RUN GSM ALGORITHM

• 24: CHANGE CHV  
• 26: DISABLE CHV  
• 28: ENABLE CHV  
• 2C: UNBLOCK CHV  
• FA: SLEEP  
• C0: GET RESPONSE  
Second Byte Value warning:  
Due to the absence of locking, the right response may not be returned for the following  
instructions (See CRSM commands).  
• C2: ENVELOPE  
• A2: SEEK  
• A4: SELECT  
Fifth Byte Value Restriction:  
For the following instructions ( Second Byte ):  
• A4: SELECT  
• 10: TERMINAL PROFILE  
• C2: ENVELOPE  
• 14: TERMINAL RESPONSE  
• A2: SEEK  
the user must make sure that the value of the fifth Byte of the instruction corresponds to  
the length of bytes (data starting from 6th byte) which follow it.  
The value of the Fifth Byte must be equal of the value: <length>/2 – 5, or the command  
is not sent to the SIM and CME_ERROR=3 is returned.  
<error>: integer type  
3: Wrong format or parameters of the command  
13: SIM no response  
<response>: hexadecimal type  
Response to the command passed on by the SIM to the MT in the format as described in  
GSM 11.11 (or 3GPP TS 51.011) (hexadecimal character format; refer +CSCS)  
Notes: The “READ RECORD” and “SEEK” actions on a transparent file return the status word  
3-9  
 
OnCell G2150I AT Command Set  
General Commands  
“9408”.  
By using the AT+CSIM command, the “READ RECORD” and “SEEK” actions return 4,”9408”  
instead of CME ERROR:13.  
Restricted SIM Access: +CRSM  
Description: By using this command instead of Generic SIM Access the +CSIM TE application  
gives easier but more limited access to the SIM database. This command transmits to the MT the  
SIM <command> and its required parameters. As a response to the command, MT sends the actual  
SIM information parameters and response data. MT error result code +CME ERROR may be  
returned when the command cannot be passed to the SIM, but failure in the execution of the  
command in the SIM is reported in <sw1> and <sw2> parameters. As for the CSIM command,  
there is no locking between two successive commands. The user should be aware of the  
precedence of the GSM application commands to the TE commands.

Multiplexing Mode: +CMUX  
Description: This command is used to manage (enable or disable) the 3GPP TS 27.010  
multiplexing protocol control channel.  
This command allows the multiplexing of 4 logical channels on a single UART. Two  
UARTs are available on the G2150I, but multiplexing can only apply to one. The client  
application may handle, by this means, up to 5 channels (4 logical multiplexed channels  
on a UART and 1 physical channel on the other UART).  
Notes on speed and autobauding:  
• The speed of the response is the same that the one of the received AT+CMUX  
command (prior to entering <mode>).  
• It is recommended that, whenever the multiplexer control channel is released, the  
modem should assume an interface rate for autobauding purposes, irrespective of any  
previous higher speed selected.  
•If a +CMUX command is issued while in any multiplexer mode, then that +CMUX  
3-12  
 
 
OnCell G2150I AT Command Set  
General Commands  
command is ignored and the modem will return a +CME ERROR: <err> response.  
Restrictions  
• Only basic option and UIH framing is supported.  
• Only convergence layers type 1 and 3 are supported.  
• Autobauding is not compliant with multiplexing mode. It is neither possible to start  
multiplexing when autobauding is active (AT+IPR=0), nor to set autobauding during  
multiplexing mode, since the multiplexer uses only a fixed baudrate. In the same way,  
the bit rate cannot be changed through the AT+IPR command while multiplexing mode  
is active. Therefore, the AT+IPR=<rate> command should not be used and will have no  
effect.  
• Before starting multiplexing mode, port speed must be configured by the  
AT+IPR=<rate> command, to be compliant with values defined in 4.24.3 Defined  
valuesfor <port_speed> parameter.  
Specific behaviors  
• In multiplexing mode, AT configuration commands (AT+CMEE for example), will be  
applied to all logical channels.  
• In multiplexing mode, unsolicited result code will be sent to all logical channels.  
• Since AT commands are grouped by classes, launching an AT command from a port  
causes the lock of all commands belonging to the same class. If an AT command of the  
locked class is launched from another port, a +CME ERROR: 536 will occur as long as  
the class is not released (at first command completion time).  
• In internal mode, if GPS is used on UART2, it is not possible to start multiplexing  
mode on UART2. In the same way, if multiplexing mode is started on UART2, it is not  
possible to use GPS in internal mode.  
• If Bluetooth is started, it is not possible to start multiplexing mode on UART2. In the  
same way, if multiplexing mode is started on UART2, it is not possible to start  
Bluetooth.  
• If TMT (Terminal Emulator) is launched on a specific UART, it is not possible to start  
multiplexing mode on this UART. TMT must be closed before starting multiplexing  
mode. On the other hand, as soon as multiplexing mode is started, HAPC can be started  
on a DLCi.  
• After an AT+CFUN=1 command during a multiplexing mode session, multiplexing  
mode is automatically restarted by the modem with previous parameters and all  
previous opened DLCs are reopened with the speed of AT+IPR? Command.  
• DCD, RI, and DTR signals are managed virtually; when V24 sets DCD, RI or DTR  
signals, an MSC frame is sent to the remote part to indicate a virtual state change. All is  
logical, no physical signal is involved.  
• +++ Escape Sequence is always available to get offline.  
• Flow control can be managed either physically, or virtually by MSC. By default, the  
G2150I manages hardware flow control on a UART, which becomes virtual on logical  
channels when some DLCs are opened.  
• At multiplexing mode session stop, it is not necessary to reset the G2150I; it  
automatically goes back into AT mode.  
• 2 timeouts are implemented for multiplexing mode connection:  
y Multiplexing mode starts the connection: 30 seconds. After this timeout, multiplexing mode is  
stopped and a previous physical port is reopened.  
y DLC inactivity timeout: 5 minutes This timeout is armed only if no DLC is opened, to avoid to  
be blocked into only DLC0 opening channel state. After this timeout, multiplexing mode  
stopped and previous physical port is reopened.

Call Control Commands  
This chapter includes information about the Call Control Commands of the OnCell G2150I.  
The following topics are covered in this chapter:  
 
 
OnCell G2150I AT Command Set  
Call Control Commands  
Dial Command: D  
Description: The ATD command is used to set a voice, data or fax call. As per GSM 02.30, the  
dial command also controls supplementary services.  
For a data or a fax call, the application sends the following ASCII string to the product  
(the bearer must be previously selected with the +CBST command):  
ATD<nb>  
Note: If a GPRS PPP session is already running, the setting of a CSD (GSM data  
call) is not supported.  
For a voice call, the application sends the following ASCII string to the product: (the  
bearer may be selected previously; if not, a default bearer is used).  
ATD<nb>; where <nb> is the destination phone number.  
Emergency calls  
The following Emergency Numbers are available without a SIM card:  
000, 08, 110, 112, 118, 119, 911 and 999.  
The following Emergency Numbers are available with a SIM card:  
when EF_ECC file is missing from SIM: 112 and 911  
when SIM includes an EF_ECC file: 112, 911 and any Emergency Numbers  
available in the EF_ECC file.  
Please note that for an international number, the local international prefix does not need to be  
set (usually 00) but does need to be replaced by the ‘+’ character.  
Example: to set up a voice call to MOXA offices from another country, the AT command is:  
“ATD+886289191230;”  
Note that some countries may have specific numbering rules for their GSM handset  
numbering.  
The response to the ATD command is one of the following:  
Verbose result code Numeric code  
(with ATVO set)  
Description

0
If the call succeeds, for voice call only  
CONNECT <speed>  
10, 11, 12, 13, 14, 15 If the call succeeds, for data calls only,  
<speed> takes the value negotiated by the  
product

Call setup failed or remote user release. Use  
the AT+CEER command to know the failure  
cause  
Direct dialing from a phonebook (stored in the SIM card) can be performed with the following  
command:  
ATD> <index>; to call <index> from the selected phonebook (by the +CPBS  
command)  
ATD> “BILL”; to call “BILL” from the selected phonebook  
ATD> mem <index> (mem is “SM”,”LD”,”MC”,”ON”,”ME”,”RC”,”MT” or “SN”,  
See +CPBS command) allows direct dialing from a phonebook number..  
Command syntax: ATD<nb>[<I>][;]

Note: Which phonebook is selected?  
Note: ADN phonebook is selected, 8 locations are  
used and 10 locations are available  
ATD>SM6;  
OK  
Note: Call index 6 from ADN phonebook  
Note: Call succeeds  
When the FDN phonebook has been locked, only numbers beginning with the digits of FDN  
phonebook entries can be called. For example, if “014629” is entered in the FDN  
phonebook all the phone numbers beginning with these 6 digits can be called. The CLIR  
supplementary service subscription can be overridden for this call only.  
“I” means “invocation” (restrict CLI presentation).  
“i” means “suppression” (allow CLI presentation).  
Control of CUG supplementary service information by “G” or “g” is allowed for this  
call only. The index and info values set with the +CCUG command are used. An  
outgoing call attempt could be refused if the AOC service is active and credit has  
expired (NO CARRIER). When trying to set up an outgoing call while there is an active  
call, the active call is first put on hold, then the call set up is carried out. As per GSM  
02.30, GSM sequences may be controlled using dial commands. These sequences can  
contain “*”, “#”, but “;” is forbidden. If the sequence is not supported or fails, +CME  
ERROR: <err> is returned. In the case where the FDN phonebook is activated, the  
sequence concerning call forwarding are allowed only if there are written in the FDN.  
See paragraph 19 Codes and values to have the list of supported sequences.

Hang-Up Command: H  
Description: The ATH (or ATH0) command is used by the application to disconnect the remote  
user. In the case of multiple calls, all calls are released (active, on-hold and waiting calls). The  
specific G2150I ATH1 command has been appended to disconnect the current outgoing call, only  
in dialing or alerting state (i.e. ATH1 can be used only after the ATD command, and before its  
terminal response (OK, NO CARRIER, ...). It can be useful in the case of multiple calls.

This chapter includes information about the Network Service Commands of the OnCell G2150I.  
The following topics are covered in this chapter:  
 
 
OnCell G2150I AT Command Set  
Network Service Commands

Operator Selection: +COPS  
Description: There are three possible ways of selecting an operator (PLMN):  
• The product is in manual mode. It then tries to find the operator specified by the  
application and if found, tries to register.  
• The product is in automatic mode. It then tries to find the home operator and if found,  
tries to register. If not found, the product automatically searches for another network.  
• The product enters into manual/automatic mode, and then tries to find an operator as  
specified by the application (as in manual mode). If this attempt fails, it enters  
automatic mode. If this is successful, the operator specified by the application is  
selected. The mobile equipment then enters into automatic mode.  
Note: The read command returns the current mode and the currently selected operator. In manual  
mode, this PLMN may not be the one set by the application (as it is in the search phase).  
These commands are not allowed during communication.  
Command syntax: To force an attempt to select and register on a network, the application must  
send the following command:  
Command syntax: AT+COPS=<mode>, [<format> [ , <oper> ] ]  
Possible responses for AT+COPS=<mode>:

Network Service Commands  
Emergency call is allowed without SIM  
+CME ERROR: 547  
Careful: Error code + CME ERROR: 546 or +CME ERROR: 547 are only returned if SIM is not  
present.  
The fact that network supports emergency calls (+CME ERROR: 547) does not imply  
that emergency calls will work without a SIM. The only way to know it is to try atd112.  
Response syntax for AT+COPS?:  
+COPS: <mode> [, <format>, <oper> ]  
Response syntax for AT+COPS=?:  
+COPS: [list of supported (<stat>, long alphanumeric <oper>, short alphanumeric  
<oper>s, numeric <oper>) s]  
Notes:  
If an incoming call occurs during a PLMN list request, the operation is aborted (+CME  
ERROR: 520) and the unsolicited RING appears.  
If SPN (Service Provider Name) is present in the SIM, it will be returned in both long  
and short alphanumeric <oper> fields. The string in the “short” field will be the SPN  
truncated to the appropriate character number (10).  
The following operations are allowed without a SIM inserted, or PIN activated:  
AT+COPS?  
: get current PLMN  
AT+COPS=?  
: List allowed PLMN

empty one.  
<NumOper>: Operator in numeric format: MCC and MNC  
<short name>: The short name of the PLMN  
<long name>: The long name of the PLMN  
Read Operator Name: +WOPN  
Description: This specific command returns the operator name in alphanumeric format, the  
numeric format being given. With E-ONS (Enhanced Operator Name Service) feature, <lac> is an  
optional parameter to read names from OPL/PNN SIM files. If it is not entered, name will be  
given with current <lac>. Note that in limited service, current <lac> is set to 0. You can also erase  
NITZ PLMN names stored in Flash memory with “AT+WOPN=3,0”. When the G2150I receives  
an NITZ (Network Information and Time Zone) message with Long Name or Short Name  
information, an entry with registered PLMN and names in message is created in flash memory.  
These names will then be used with +COPS,+COPN,+WOPN, +CPOL commands with the  
priority order defined in 3GPP TS 22.101. The G2150I supports only network names with GSM  
default alphabet coding scheme. The user can choose which of the following methods will be used  
for getting PLMN names with command “AT+WOPN=4,<PlmnOns>“.  
The priority order is:  
1 - E-ONS  
2 – CPHS  
First entry if on Home PLMN, or matching entry if existing in OPL/PNN SIM files  
if on Home PLMN, use SIM file CPHS ONS (0x6F14) for Long Name if present  
and SIM file CPHS SONS (0x6F18) for short name if present (if not, reuse SIM  
file CPHS ONS)  
3 – SPN  
If on Home PLMN, use SIM file SPN (0x6F46) if present  
4 – NITZ  
if there is a matching entry in the list of names received so far, use it. Note that in  
France for example, all the operators use NITZ message for Date and Time feature,  
but not for PLMN names, so the list is always empty. In France, an NITZ message  
is sent on a GPRS attachment.  
FLASH If there is a matching entry in the flash PLMN list (created by +WOLM), use it.  
PLMN names in ROM defined according to MoU SE.13 and NAPRD Operator  
Names documents  
5 - ROM  
Once a long name is found following this priority order, it is given as a response to the AT  
command.  
Refer to 3GPP TS 24.008, 3GPP TS 23.040, 3GPP TS 22.042 and COMMON PCN HANDSET  
SPECIFICATION CPHS Phase 2 v4.2 for more information.

Security Commands  
This chapter includes information about the Security Commands of the OnCell G2150I.  
The following topics are covered in this chapter:  
 
 
OnCell G2150I AT Command Set  
Security Commands  
Enter PIN: +CPIN  
Description: This command is used to enter the ME passwords (CHV1 / CHV2 / PUK1 / PUK2,  
etc.), that are required before any ME functionality can be used. CHV1/CHV2 is between 4 and 8  
digits long, PUK1/PUK2 is only 8 digits long.  
If the user application tries to make an outgoing call before the SIM PIN code (CHV1)  
has been confirmed, then the product will refuse the “ATD” command with a “+CME ERROR:  
11” (SIM PIN required).  
The application is responsible for checking the PIN after each reset or power on if the  
PIN was enabled.  
Command syntax: AT+CPIN=<pin>  
Command  
Possible responses  
AT+CPIN=1234  
OK  
Note: Enter PIN  
Note: PIN code is correct  
AT+CPIN=5678  
+CME ERROR: 3  
Note: Enter PIN  
Note: Operation not allowed, PIN previously entered  
After 3 unsuccessful attempts to enter the PIN (Personal Identification Number), the  
PUK (Personal Unblocking Key) will be required. PUK validation forces the user to enter a new  
PIN code as a second parameter and this will be the new PIN code if PUK validation succeeds.  
CHV1 is then enabled if PUK1 is correct. The application therefore uses this command:  
AT+CPIN=<Puk>,<NewPin>  
Command  
Possible responses  
AT+CPIN=00000000,1234  
+CME ERROR: 16  
Note: Enter PUK and new PIN  
Note: Incorrect PUK  
AT+CPIN=12345678,1234  
OK  
Note: Enter PUK and new PIN, 2nd attempt  
Note: PUK correct, new PIN stored  
To ascertain which code must be entered (or not), the following query command can be used:  
AT+CPIN?  
The possible responses are:  
+CPIN: READY  
+CPIN: SIM PIN  
ME is not pending for any password  
CHV1 is required  
+CPIN: SIM PUK  
+CPIN: SIM PIN2  
+CPIN: SIM PUK2  
+CPIN: PH-SIM PIN  
+CPIN: PH-NET PIN  
+CME ERROR: <err>  
PUK1 is required  
CHV2 is required  
PUK2 is required  
SIM lock (phone-to-SIM) is required  
Network personalization is required  
SIM failure (13) absent (10) etc  
Please note that in this case the mobile equipment does not end its response with the OK string.  
The response +CME ERROR: 13 (SIM failure) is returned after 10 unsuccessful PUK attempts.  
The SIM card is then out of order and must be replaced by a new one.  
Example: 3 failed PIN validations + 1 successful PUK validation

+CPIN: READY  
The product is ready  
If the user tries to do something that requires PIN2 (CHV2), the product will refuse the action with  
a “+ CME ERROR: 17” (SIM PIN2 required). The product then waits for SIM PIN2 to be given.  
Of course, if SIM PIN2 is blocked, SIM PUK2 is required instead of SIM PIN2.  
For example, the product needs PIN2 to write in the fixed dialing phonebook (FDN), so if SIM  
PIN2 authentication has not been performed during the current session, SIM PIN2 is required.

Note: Now writing in FDN is allowed  
Please note that the product only requests PIN2 or PUK2 once. Therefore, if they are not entered  
properly, the next + CPIN? command will return “+CPIN: READY”.  
Defined values:  
<pin> Personal Identification Number. 4-digit number.  
<puk> Personal Unblocking Key needed to change the PIN. 8-digit number.  
Enter PIN2: +CPIN2  
Description: This specific command is used to validate the PIN2 code (CHV2), or to validate the  
PUK2 code (UNBLOCK CHV2) and to define a new PIN Code. Of course, the +CPIN command  
allows PIN2 or PUK2 codes to be validated, but only when the last command executed resulted in  
PIN2 authentication failure.  
PIN2 length is between 4 and 8 digits, PUK2 length is 8 digits only.

New Message Acknowledgement: +CNMA  
Description: This command allows reception of a new message routed directly to the TE to be  
acknowledged.  
• In TEXT mode, only positive acknowledgement to the network (RP-ACK) is possible.  
• In PDU mode, either positive (RP-ACK) or negative (RP-ERROR) acknowledgement  
to the network is possible.  
Acknowledge with +CNMA is possible only if the +CSMS parameter is set to 1  
(+CSMS=1) when a +CMT or +CDS indication is shown (see +CNMI command). If no  
acknowledgement is given within the network timeout, an RP-ERROR is sent to the network, the  
<mt> and <ds> parameters of the +CNMI command are then reset to zero (do not show new  
message indication).  
Command syntax in text mode: AT+CNMA  
Command syntax in PDU mode:  
AT+CNMA [ = <n> [ , <length> [ <CR>

Description: The message formats supported are text mode and PDU mode. In PDU mode, a  
complete SMS Message including all header information is given as a binary string (in  
hexadecimal format). Therefore, only the following set of characters is allowed: {0, 1, 2, 3, 4, 5, 6,  
7, 8, 9, A, B, C, D, E, F}. Each pair or character is converted to a byte (e.g.: ‘41’ is converted to  
the ASCII character ‘A’, whose ASCII code is 0x41 or 65). In Text mode, all commands and  
responses are in ASCII characters. The selected format is stored in EEPROM by the +CSAS  
command.

The <pdu> message is composed of the SC address (00 means no SC address given, use default  
SC address read with +CSCA command) and the TPDU message.  
In this example, the length in bytes of the TPDU buffer is 14, coded as GSM 03.40  
In this case the TPDU is: 0x01 0x03 0x06 0x91 0x21 0x43 0x65 0x00 0x00 0x04 0xC9 0xE9  
0x34 0x0B, which means regarding GSM 03.40:  
<fo>  
0x01 (SMS-SUBMIT, no validity period)  
<mr>  
<da>  
<pid>  
<dcs>  
(TP-MR) 0x03 (Message Reference)  
(TP-DA) 0x06 0x91 0x21 0x43 0x65 (destination address +123456)  
(TP-PID) 0x00 (Protocol Identifier)  
(TP-DCS) 0x00 (Data Coding Scheme: 7 bits alphabet)  
<length> (TP-UDL) 0x04 (User Data Length, 4 characters of text)  
TP-UD 0xC9 0xE9 0x34 0x0B (User Data: ISSY)  
TPDU in hexadecimal format must be converted into two ASCII characters. For example, the byte  
0x2A is presented to the ME as two characters ‘2’ (ASCII 50) and ‘A’ (ASCII 65).

b1=0 & b0=0 -> SMS-DELIVER (in the direction SC to MS)  
b1=0 & b0=1 -> SMS-SUBMIT (in the direction MS to SC)  
In text mode <vp> is only coded in “relative” format. The default value is 167 (24 hours).  
This means that one byte can describe different values:

Description: This command is used to indicate to which service center the message must be sent.  
The product has no default value for this address. If the application tries to send a message without  
having indicated the service center address, an error will be generated. Therefore, the application  
must indicate the SC address when initializing the SMS. This address is then permanently valid.  
The application may change it if necessary.

Cell Broadcast Message Identifiers: +WCBM  
Description: This specific command is used to read the EF-CBMI SIM file.  
Remark: The EF-CBMI file is not used with the +CSCB command.  
The application should read this file (using AT+WCBM?) and combine the Message  
Identifiers with those required by the application.

Message Overwriting: +WMGO  
Description: The +WMGO command is used to specify a location in the SIM or Flash memory,  
for the next SMS storing with +CMGW command. The defined location is used only once:  
+WMGO has to be used again to perform another overwrite.  
Important notes:  
y If the external application specifies a free location, and an incoming message is received  
before the AT+CMGW command occurs, the product may store the incoming message at  
the specified available location. If the user then issues an AT+CMGW command without  
changing the location with another AT+WMGO, the received message will be overwritten.  
y The location number is not kept over a software reset.

Data Commands  
Using AT Commands During a Data Connection  
To use AT Commands during a data connection (e.g., while the product is in online mode), it is  
necessary either to switch to offline mode, or to use the specific +WMUX command to enable  
Commands / Data multiplexing.  
Switch from online to offline mode:  
To switch from online mode to offline mode, the “+++” sequence must be sent. Following this, the  
product gets back to offline mode with an “OK” response, and a AT command can be sent.  
Note: The “+++” sequence will only work with the +ICF command using one of the following  
settings:  
• 8 data bits, with no parity  
• 7 data bits, with even parity  
Switch from offline to online mode: See the ATO command description.  
Bearer Type Selection: +CBST  
Description: This command applies to both outgoing and incoming data calls, but in a different  
way. For an outgoing call, the two parameters (e.g. <speed> and <ce>) are meaningful, whereas  
for an incoming call, only the <ce> parameter is used.  
Note 1) For incoming calls, if <ce> is set to ‘T’ only and the network offers only ‘NT’  
or vice versa, then the call is released.  
Note 2) Values 2 and 3 for <ce> parameter are equivalent to former values 100 and 101.  
Those values are managed for compatibility purposes, but they shouldn’t be used in new code (2  
as former 100, and 3 as former 101).

y The serial autobauding feature is supported, and covers the following serial speeds (only):  
2400, 4800, 9600, 19200, 38400, 57600 bps. Beyond those serial speeds, proper operation  
of the G2150I is not guaranteed.  
y Any AT command issued by the DTE must start with both capital ‘A’ and ‘T’ (or ‘/’) or  
both lower case ‘a’ and ‘t’ (or ‘/’), otherwise the DCE may return some garbage characters  
and become desynchronized. Should this happen, the DTE simply issues ‘AT\r’ (at 2400 or  
4800 bauds) once or twice or just ‘AT’ (at 9600 bauds) to resynchronize the modem.  
y The DTE waits for 1 ms after receiving the last character of the AT response (which is  
always ‘\n’ or 0x0A) to send a new AT command at either the same rate or a new rate.  
Should this delay be ignored, the DCE can become desynchronized. Once again, sending  
‘AT\r’ once or twice or just ‘AT’ causes the DCE to recover.  
Caution: when starting up, if autobauding is enabled and no AT command has yet been received,  
the product sends all unsolicited responses (like RING) at 9600 baud.

Notes:  
• Setting a character framing different from 8N1 will disable autobauding if it was activated.  
Setting it back to 8N1 will not re-enable auto-baud.  
• Setting the framing to 8N1 will let autobauding be enabled, if it was already enabled (implying  
framing was already 8N1).  
DTE-DCE Local Flow Control: +IFCR

1: XOn/Xoff local circuit 103 ( not supported)  
2: RTS (supported)  
3: Xon/Xoff global on circuit 103 (not supported)  
Important note: When this parameter is set to 2 (DTE invokes flow control through RTS) DCE  
behavior is as follows:  
If the DCE has never detected RTS in the high (or ON) condition since startup, then it ignores  
RTS (assuming this signal is not connected).  
As soon as the DCE detects RTS high the signal acts on it. Therefore subsequent RTS  
transition to OFF will prevent the DCE from sending any further data in both online and offline  
modes.  
This behavior allows the user to use the default settings (hardware flow control) and leave RTS  
disconnected. In the case where RTS is connected and is high at least once, it acts on the DCE.  
< DTE_by_DCE >  
0: none (supported)  
1: Xon/Xoff circuit 104 (not supported)  
2: CTS (supported)  
When this parameter is set to 0 (none) then CTS is kept high all the time.

Define PDP Context: + CGDCONT  
Description: This Command specifies PDP context parameter values for a PDP context  
identified by the local context identification parameter, <cid>. Four PDP contexts can be defined  
through MOXA software. A special form of the set command, +CGDCONT= <cid> causes the  
values for context number <cid> to become undefined. The test command returns values supported  
as a compound value. If the MT supports several PDP types, <PDP_type>, 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. The test command returns values supported as a compound value.  
If the MT supports several PDP types, <PDP_type), the parameter value ranges for each  
<PDP_type> are returned on a separate line.

<PDP_address>: a string parameter that identifies the MT in the address space applicable to  
the PDP. If the value is null or omitted, then a value may be provided by the TE during the  
PDP startup procedure, or a dynamic address will be requested. The read form of the command  
will return the null string even if an address has been allocated during the PDP startup  
procedure. The allocated address may be read using the +CGPADDR command.  
<d_comp> a numeric parameter that controls PDP data compression

Notes:  
The data compression algorithm provided in SNDCP is V.42bis.  
4 CIDs are available to specify 4 PDP context but only 11 NSAPI are available for  
PDP activation. 4 PDP contexts can be specified with only one activated at the same  
time.  
Quality of Service Profile (Requested): +CGQREQ  
Description: This command allows the TE to specify a Quality of Service Profile that is used  
when the MT sends an Activate PDP Context Request message to the network. The set command  
specifies a profile for the context identified by the local context identification parameter, <cid>.  
Since this is the same parameter that is used in the +CGDCONT command, the +CGQREQ  
command is effectively an extension to the +CGDCONT command. The QoS profile consists of a  
number of parameters, each of which may be set to a separate value. A special form of the set  
command, +CGQREQ= <cid> causes the requested profile for context number <cid> to become  
undefined. The read command returns the current settings for each defined context. 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.

Quality of Service Profile (Minimum acceptable): +CGQMIN  
Description: This command allows the TE to specify a minimum acceptable profile that is  
checked by the MT against the negotiated profile returned in the Activate PDP Context Accept  
message. The set command specifies a profile for the context identified by the local context  
identification parameter, <cid>. Since this is the same parameter that is used in the +CGDCONT  
command, the +CGQMIN command is an extension to the +CGDCONT command. The QoS  
profile consists of a number of parameters, each of which may be set to a separate value. A special  
form of the set command, +CGQMIN= <cid> causes the minimum acceptable profile for context  
number <cid> to become undefined. In this case, no check is made against the negotiated profile.  
The read command returns the current settings for each defined context. 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.

GPRS Attach or Detach: +CGATT  
Description: The execution 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.25ter command state. If  
the MT is already in the requested state, the command is ignored and the OK is returned. If the  
requested state cannot be achieved because the GPRS is not supported by the MT, an ERROR or  
+CME ERROR response is returned. Extended error responses are enabled by the +CMEE  
command. Any active PDP contexts will be automatically deactivated when the attachment state  
changes to detached. The read command returns the current GPRS service state. The test command  
is used for requesting information on the supported GPRS service states..

PDP Context Activate or Deactivate: +CGACT  
Description: The execution command is used to activate or deactivate the specified PDP  
context(s). After the command has completed, the MT remains in V.25ter command state. If any  
PDP context is already in the requested state, the state for that context remains unchanged. If the  
requested state for any specified context cannot be achieved, an ERROR or +CME ERROR  
response is returned. Extended error responses are enabled by the +CMEE command. 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 the attach fails then the MT  
responds with ERROR, or if extended error responses are enabled, with the appropriate  
failure-to-attach error message. If no <cid>s are specified the activation form of the command  
activates the first possible within the defined contexts. If no <cid>s is specified the deactivation  
form of the command deactivates all active contexts. One PDP contexts can be activated through  
MOXA software at the same time. The read command returns the current activation states for all  
the defined PDP contexts. The test command is used for requesting information on the supported  
PDP context activation states.

GPRS Commands  
Enter Data State: +CGDATA  
Description: This command causes the MT to perform the necessary actions to set up  
communication between the TE and the network. This may include performing a GPRS attach and  
one PDP context activation. If the <cid> value is not defined to the MT, it will return an ERROR  
or +CME ERROR response. Otherwise, the MT issues the intermediate result code CONNECT  
and enters V.25ter online data state. GPRS attachment and PDP context activation procedures may  
take place prior to or during the PDP startup if they have not already been performed using the  
+CGATT and +CGACT commands. If no <cid> is given, the MT attempts to activate the context  
with available information. The other context parameters are set to their default values (No APN,  
default QOS parameters, dynamic IP address requested). If the activation is successful, data  
transfer may proceed. After data transfer and layer 2 protocol termination procedure completion,  
the V.25ter command state is re-entered and the MT returns the final result code OK. In case of  
abnormal termination or start up, the V.25ter command state is re-entered and the MT returns the  
final result code NO CARRIER or, if enabled, +CME ERROR. Attach, activate, and other errors  
may be reported. This command may be used in both normal and modem compatibility modes.

The mobile equipment has forced a context deactivation. The <cid> that was used  
to activate the context is provided if known to the MT.  
+CGEV: NW DETACH  
The network has forced a GPRS detach. This implies that all active contexts have  
been deactivated. These are not reported separately.  
+CGEV: ME DETACH  
The mobile equipment has forced a GPRS detach. This implies that all active  
contexts have been deactivated. These are not reported separately.

Request GPRS IP Service: ‘D’  
Description: This command causes the MT to perform whatever actions are necessary to  
establish communication between the TE and the external PDN. The V.25ter ‘D’ (Dial) command  
causes the MT to enter the V.25ter online data state and, with the TE, to start the specified layer 2  
protocol. The MT return CONNECT to confirm acceptance of the command prior to entering the  
V.25ter online data state. No further commands may follow on the AT command line.  
The detailed behavior after the online data state has been entered is described briefly in  
clause 9, for IP, of GSM 07.60. GPRS attachment and PDP context activation procedures may take  
place prior to or during the PDP startup if they have not already been performed using the  
+CGATT and +CGACT commands.  
If <cid> is supported, its usage is the same as in the +CGDATA command. The  
+CGDCONT, +CGQREQ, etc., commands may then be used in the modem initialization AT  
command string to set values for PDP type, APN, QoS, etc.  
If <cid> is not supported or is supported but omitted, the MT attempt to activate the  
context using the ‘Empty PDP type’ (GSM 04.08). (No PDP address or APN is sent in this case  
and only one PDP context subscription record is present in the HLR for this subscriber.)  
Note: If a GPRS PPP session is already running, the setting of a CSD (GSM data call) is  
not supported.

Network Requested PDP Context Activation  
In this mode of operation, the MT behaves like an answering modem and accepts the normal  
V.25ter commands associated with answering a call. If GPRS-specific configuration commands  
are required, they may be sent to the MT as part of the modem initialization commands.  
The +CGAUTO command is used to select modem compatibility mode.  
Automatic response to a network request for PDP context activation ‘S0’  
The V.25ter ‘S0=n’ (Automatic answer) command may be used to turn off (n=0) and on (n>0) the  
automatic response to a network request for a PDP context activation  
When the ‘S0=n’ (n>0) command is received, the MT attempt to perform a GPRS attach if it is not  
already attached. Failure will result in ERROR being returned to the TE. Subsequently, the MT  
will announce a network request for PDP context activation by issuing the unsolicited result code  
RING to the TE, followed by the intermediate result code CONNECT. The MT then enters  
V.25ter online data state and follows the same procedure as it would after having received a  
+CGANS=1 with no <L2P> or <cid> values specified.  
Note: The ‘S0=n’ (n=0) command does not perform an automatic GPRS detach.  
Manual acceptance of a network request for PDP context activation ‘A’  
The V.25ter ‘A’ (Answer) command may be used to accept a network request for a PDP context  
activation announced by the unsolicited result code RING. The MT responds with CONNECT,  
enters V.25ter online data state and follows the same procedure as it would after having received a  
+CGANS=1 with no <cid> value specified. It is an error to issue the ‘A’ command when there is  
no outstanding network request.  
Manual rejection of a network request for PDP context activation ‘H’  
The V.25ter ‘H’ or ‘H0’ (On-hook) command may be used to reject a network request for PDP  
context activation announced by the unsolicited result code RING. The MT responds with OK. It  
is an error to issue the ‘H’ command when there is no outstanding network request.  
Note: This is an extension to the usage of the ‘H’ command that is described in ITU-T V.25ter.  
Automatic Response to a Network Request for PDP  
Context Activation: +CGAUTO  
Description: The set command disables or enables an automatic positive response (auto-answer)  
to the receipt of a Request PDP Context Activation message from the network. It also provides  
control over the use of the V.25ter basic commands ‘S0’, ‘A and ‘H’ for handling network  
requests for PDP context activation. The setting does not affect the issuing of the unsolicited result  
code RING or +CRING.  
The test command returns values of <n> supported by the MT as a compound value.  
When the +CGAUTO=0 command is received, the MT will not perform a GPRS detach  
if it is attached. Subsequently, when the MT announces a network request for PDP context  
activation by issuing the unsolicited result code RING or +CRING, the TE may manually accept  
or reject the request by issuing the +CGANS command or may simply ignore the network request.  
When the +CGAUTO=1 command is received, the MT will attempt to perform a GPRS  
attach if it is not already attached. Failure will result in ERROR or, if enabled, +CME ERROR  
being returned to the TE. Subsequently, when the MT announces a network request for PDP  
context activation by issuing the unsolicited result code RING or +CRING to the TE, this is  
followed by the intermediate result code CONNECT. The MT then enters V.25ter online data state  
and follows the same procedure as it would after having received a +CGANS=1 with <cid> values  
specified.

Manual Response to a Network Request for PDP Context  
Activation: +CGANS  
Description: The execution command requests the MT to respond to a network request for  
GPRS PDP context activation that has been signaled to the TE by the RING or +CRING:  
unsolicited result code. The <response> parameter allows the TE to accept or reject the  
request.  
If <response> is 0, the request is rejected and the MT returns OK to the TE.  
If <response> is 1, the following procedure is followed by the MT.  
PDP context activation procedures take place prior to or during the PDP startup.  
One <cid> may be specified in order to provide the values needed for the context  
activation request.  
10-15  
 
 
OnCell G2150I AT Command Set  
GPRS Commands  
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 a <cid> is given its information must match the PDP type and PDP address in the  
network request as follows:  
The PDP type must match exactly.  
The PDP addresses are considered to match if they are identical or if the address in  
the context definition is unspecified.  
If any of this information is in conflict, the command will fail.  
The context is activated using the values for PDP type and PDP address provided by the  
network, together with the other information found in the PDP context definition. An  
APN may or may not be required, depending on the application.  
If no <cid> is given, the MT will attempt to activate the context using the values for  
PDP type and PDP address provided by the network, together with any other relevant  
information to the MT. The other context parameters will be set to their default values.  
If the activation is successful, data transfer may proceed.  
After data transfer is complete, and the layer 2 protocol termination procedure has  
completed successfully, the V.25ter command state is re-entered and the MT returns the  
final result code OK. In the event of an erroneous termination or a failure to startup, the  
V.25ter command state is re-entered and the MT returns the final result code NO  
CARRIER or, if enabled, +CME ERROR. Attach, activate, and other errors may be  
reported. It is also an error to issue the +CGANS command when there is no  
outstanding network request. This command may be used in both normal and modem  
compatibility modes.

+CGPADDR=?  
+CGPADDR: (list of defined <cid>s)  
OK  
Defined values:  
<cid>: a numeric parameter that specifies a particular PDP context definition. If no <cid> is  
specified, the addresses for all defined contexts are returned.  
<PDP_address>: a string that identifies the MT in the address space applicable to the PDP. The  
address may be static or dynamic. For a static address, it will be the one set by the  
+CGDCONT command when the context was defined. For a dynamic address it will be  
the one assigned during the last PDP context activation that used the context definition  
referred to by <cid>. <PDP_address> is omitted if none is available.

Cellular Result Codes: +CRC  
Description: This command enables a more detailed ring indication, in case of an incoming call  
(voice or data). Instead of the string “RING”, an extended string is used to indicate which type of  
call is ringing (e.g. +CRING: VOICE).  
These extended indications are:  
+CRING: ASYNC  
+CRING: REL ASYNC  
+CRING: VOICE  
+CRING: FAX

GPRS Commands  
GPRS network request for PDP context activation  
+CRING: GPRS  
If the MT is unable to announce to the TE the network’s request (for example it is in V.25ter on  
line data state) the MT rejects the request. No corresponding unsolicited result code is issued when  
the MT returns to a command state.  
Command syntax: See Chapter 7. Cellular result codes +CRC.  
Defined values: No parameter.  
Service Reporting Control: +CR  
Description: This command enables a more detailed service reporting, in case of an incoming or  
outgoing data call. Before sending the CONNECT response to the application, the G2150I will  
precise the type of data connection that have been established.  
These reports types are:  
+CR: ASYNC  
+CR: REL ASYNC  
+CR: GPRS  
For asynchronous transparent  
For asynchronous non-transparent

GPRS Commands  
GPRS Parameter Customization: + WGPRS  
Description: This command modifies some G2150I GPRS parameters:  
the ATTACH-STATUS (the ME does or not perform automatically a GPRS  
attachment after initialization),  
the PDP-INIT-STATUS (activates automatically or not some defined PDP contexts  
after initialization) and  
the user-defined multislot class. This parameter represents the GPRS class chosen by  
the user to perform power saving (by reducing TX (or uplink) time slots).  
In addition, this command allows:  
set automatically “ACTIVABLE” some defined PDP contexts after initialization  
set some parameters for PALM® OS software: PPP Silent Mode (PPP waits for PPP  
Client to start the dialog) and Slow CONNECT (due to the delay of the processing  
of PALM® OK, the CONNECT is sent one second after the dialing command  
request)  
IMPORTANT NOTE: The G2150I must be rebooted to activate the new setup except  
for <mode> 3, 5, 6 and 7 (please refer to Defined Values paragraph).

Remark: When the G2150I is set in “CG” class, the ME always make automatically a GPRS  
attachment after init, so AT+WGPRS? always give +WGPRS: 0,0 for the parameter 0.  
Note: Default value for mode 7 is 0; in this case, no automatic GPRS reconnection to new  
operator is done when reaching border areas.

GSM 04.11 Annex E-2: Mobile Originating SM-Transfer  
These error causes could appear for SMS commands (+CMGS, +CMSS, +CMGD…)  
Cause No. 1: “Unassigned (unallocated) number”  
This cause indicates that the destination requested by the Mobile Station cannot be reached  
because, although the number is in a valid format, it is not currently assigned  
(allocated).  
Cause No. 8: “Operator determined barring”  
This cause indicates that the MS has tried to send a mobile originating short message when the  
MS's network operator or service provider has forbidden such transactions.  
Cause No. 10: “Call barred”  
This cause indicates that the outgoing call barred service applies to the short message service for  
the called destination.  
A-6  
 
 
OnCell G2150I AT Command Set  
Result Codes, Failure Causes,, and Other Tables  
Cause No. 21: “Short message transfer rejected”  
This cause indicates that the equipment sending this cause does not wish to accept this short  
message, although it could have accepted the short message since the equipment  
sending this cause is neither busy nor incompatible.  
Cause No. 27: “Destination out of service”  
This cause indicates that the destination indicated by the Mobile Station cannot be reached because  
the interface to the destination  
is not functioning correctly. The term “not functioning correctly” indicates that a signaling  
message was unable to be delivered to the remote user; e.g., a physical layer or data link  
layer failure at the remote user, user equipment off-line, etc.  
Cause No. 28: “Unidentified subscriber”  
This cause indicates that the subscriber is not registered in the PLMN (e.g.. IMSI not known)  
Cause No. 29: “Facility rejected”  
This cause indicates that the facility requested by the Mobile Station is not supported by the  
PLMN.  
Cause No. 30: “Unknown subscriber”  
This cause indicates that the subscriber is not registered in the HLR (e.g.. IMSI or directory  
number is not allocated to a subscriber).  
Cause No. 38: “Network out of order”  
This cause indicates that the network is not functioning correctly and that the condition is likely to  
last a relatively long period of time;  
e.g., immediately reattempting the short message transfer is not likely to be successful.  
Cause No. 41: “Temporary failure”  
This cause indicates that the network is not functioning correctly and that the condition is not  
likely to last a long period of time; e.g., the Mobile Station may wish to try another  
short message transfer attempt almost immediately.  
Cause No. 42: “Congestion”  
This cause indicates that the short message service cannot be serviced because of high traffic.  
Cause No. 47: “Resources unavailable, unspecified”  
This cause is used to report a resource unavailable event only when no other cause applies.  
Cause No. 69: “Requested facility not implemented”  
This cause indicates that the network is unable to provide the requested short message service.  
Cause No. 81: “Invalid short message transfer reference value”  
This cause indicates that the equipment sending this cause has received a message with a short  
message reference which is not currently in use on the MS-network interface.  
Cause No. 95: “Invalid message, unspecified”  
This cause is used to report an invalid message event only when no other cause in the invalid  
message class applies.  
Cause No. 96: “Invalid mandatory information”  
This cause indicates that the equipment sending this cause has received a message where a  
A-7  
 
OnCell G2150I AT Command Set  
Result Codes, Failure Causes,, and Other Tables  
mandatory information element is missing and/or has a content error (the two cases are  
undistinguishable).  
Cause No. 97: “Message type non-existent or not implemented”  
This cause indicates that the equipment sending this cause has received a message with a message  
type it does not recognize either because this is a message not defined or defined but not  
implemented by the equipment sending this cause.  
Cause No. 98: “Message not compatible with short message protocol state”  
This cause indicates that the equipment sending this cause has received a message such that the  
procedures do not indicate that this is a permissible message to receive while in the  
short message transfer state.  
Cause No. 99: “Information element non-existent or not implemented”  
This cause indicates that the equipment sending this cause has received a message which includes  
unrecognized information elements because the information element identifier is not  
defined or it is defined but not implemented by the equipment sending the  
cause. However, the information element is not required to be present in the message so that the  
equipment sends the cause to process the message.  
Cause No. 111: “Protocol error, unspecified”  
This cause is used to report a protocol error event only when no other cause applies.  
Cause No. 127: “Interworking, unspecified”  
This cause indicates that there has been interworking with a network which does not provide  
causes for actions it takes; thus, the precise cause for a message which is being sent  
cannot be determineed. All values other than specified should be treated as error Cause  
No 41.
