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.
OnCell G2150I
User
GSM network
TE
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
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.

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

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.

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.

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
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.

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>:

<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.

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

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.

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

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.

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

b4=0 & b3=0 -> <vp> field is not present
b4=1 & b3=0 -> <vp> field is present in relative format
Other formats (absolute & enhanced) are not supported.
RD: Reject Duplicates, b2=1 to instruct the SC to reject an SMS-SUBMIT for an SM still
held in the SC which has the same <mr> and the same <da> as the previously submitted SM
from the same <oa>
MTI: Message Type Indicator
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:
VP value
Validity period value
0 to 143
(VP + 1) x 5 minutes (up to 12 hours)
12 hours + ( (VP – 143) x 30 minutes )
144 to 167
168 to 196
197 to 255
(VP – 166) x 1 day
(VP – 192) x 1 week
<pid> is used to indicate the higher layer protocol being used or indicates inter-working with a
certain type of telematic device. For example, 0x22 is for group 3 fax, 0x24 is for voice telephone,
0x25 is for ERMES (European Radio Messaging System).
<dcs> is used to determine the way the information is encoded. Compressed text is not
supported. Only GSM default alphabet, 8 bit data and UCS2 alphabet are supported.

Service Center Address: +CSCA
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.

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).

V24-V25 Commands
Fixed DTE Rate: +IPR
Description: This command specifies the data rate at which the DCE will accept commands.
Notes:
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.

0: Odd (supported)
1: Even (supported)
2: Mark (supported)
3: Space (supported)
4: None (supported)
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).

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)

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_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

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.

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.
Notes:
y This command has the same effects than ATD*99***.
y If a GPRS PPP session is already running, the setting of a CSD (GSM data call) is not
supported.

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.

GPRS Commands
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.

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.

NB: Type 1 MS are not required to transmit and receive at the same time
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.

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

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.
