1.5 AT Interface Synopsis
1.5.1 Interface Settings
Between Customer Application and the Module, standardized RS–232 interface is used for the
communication, and default values for the interface settings as following:
115200bps, 8 bit data, no parity, 1 bit stop, no data stream control.
1.5.2 AT Commands Syntax
The "AT" or "at" or "aT" or "At" prefix must be included at the beginning of each command line (except A/
and +++), and the character <CR> is used to finish a command line so as to issue the command line to the
module. It is recommended that a command line only includes a command.
When Customer Application issues a series of AT commands on separate command lines, leave a pause
between the preceding and the following command until information responses or result codes are retrieved
by Customer Application, for Examples, "OK" is appeared. This advice avoids too many AT commands are
issued at a time without waiting for a response for each command.
The AT Command set implemented by A7600 Series is a combination of 3GPP TS 27.005, 3GPP TS 27.007
and ITU-T recommendation V.25ter and the AT commands developed by SIMCom.
In the present document, AT commands are divided into three categories: Basic Command, S Parameter
Command, and Extended Command.
1. Basic Command
The format of Basic Command is "AT<x><n>" or "AT&<x><n>", where "<x>" is the command name, and
www.simcom.com 43 / 652
Page 45
A76XX Series_AT Command Manual_V1.09
Table 1: Types of AT commands and responses
Test Command
AT+<x>=?
The mobile equipment returns the list of parameters and value
ranges set with the corresponding Write Command or by internal
processes.
Read Command
AT+<x>?
This command returns the currently set value of the parameter or
parameters.
Write Command
AT+<x>=<…>
This command sets the user-definable parameter values.
Execution Command
AT+<x>
The execution command reads non-variable parameters affected
by internal processes in the GSM engine.
The character "+" between the prefix "AT" and command name may be replaced by other character. For
Examples, using "#" or "$"instead of "+".
NOTE
"<n>" is/are the parameter(s)for the basic command which is optional. An Examples of Basic Command is
"ATE<n>", which informs the TA/DCE whether received characters should be echoed back to the TE/DTE
according to the value of "<n>"; "<n>" is optional and a default value will be used if omitted.
2. S Parameter syntax
The format of S Parameter Command is "ATS<n>=<m>", "<n>" is the index of the S–register to set, and
"<m>" is the value to assign to it. "<m>" is optional; in this case, the format is "ATS<n>", and then a default
value is assigned.
3. Extended Syntax
The Extended Command has several formats, as following table list:
4. Combining AT commands on the same Command line
You can enter several AT commands on the same line. In this case, you do not need to type the "AT" or "at"
prefix before every command. Instead, you only need type "AT" or "at" the beginning of the command line.
Please note to use a semicolon as the command delimiter after an extended command; in basic syntax or S
parameter syntax, the semicolon need not enter, for Examples:
ATE1Q0S0=1S3=13V1X4;+IFC=0,0;+IPR=115200.
The Command line buffer can accept a maximum of 3071 characters (counted from the first command
without "AT" or "at" prefix). If the characters entered exceeded this number then none of the Command will
executed and TA will return "ERROR".
5. Entering successive AT commands on separate lines
When you need to enter a series of AT commands on separate lines, please Note that you need to wait the
final response (for Examples OK, CME error, CMS error)of last AT Command you entered before you enter
www.simcom.com 44 / 652
Page 46
A76XX Series_AT Command Manual_V1.09
the next AT Command.
1.5.3 Supported character sets
The A7600 Series AT Command interface defaults to the IRA character set. The A7600 Series supports the
following character sets:
GSM format
UCS2
IRA
The character set can be set and interrogated using the "AT+CSCS" Command (3GPP TS 27.007). The
character set is defined in GSM specification 3GPP TS 27.005.
The character set affects transmission and reception of SMS and SMS Cell Broadcast messages, the entry
and display of phone book entries text field and SIM Application Toolkit alpha strings.

exceed 900 milliseconds.
ATO Switch from command mode to data mode
NOTE
2.2.5 +++ Switch from data mode to command mode
This command is only available during a connecting PS data call. The +++ character sequence causes the
TA to cancel the data flow over the AT interface and switch to Command Mode. This allows to enter AT
commands while maintaining the data connection to the remote device.
Examples
2.2.6 ATO Switch from command mode to data mode
ATO is the corresponding command to the +++ escape sequence. When there is a PS data call connected
and the TA is in Command Mode, ATO causes the TA to resume the data and takes back to Data Mode.

4.2.1 AT+CREG Network registration
This command is used to control the presentation of an unsolicited result code +CREG: <stat> when <n>=1
and there is a change in the ME network registration status, or code +CREG: <stat>[,<lac>,<ci>] when
<n>=2 and there is a change of the network cell.
Read command returns the status of result code presentation and an integer <stat> which shows whether
the network has currently indicated the registration of the ME. Location information elements <lac> and <ci>
are returned only when <n>=2 and ME is registered in the network.

4.2.2 AT+COPS Operator selection
Write command forces an attempt to select and register the GSM/UMTS network operator. <mode> is used
to select whether the selection is done automatically by the ME or is forced by this command to operator
<oper> (it shall be given in format <format>). If the selected operator is not available, no other operator shall
be selected (except <mode>=4). The selected operator name format shall apply to further read commands
(AT+COPS?)also. <mode>=2 forces an attempt to deregister from the network. The selected mode affects
to all further network registration (e.g. after <mode>=2, ME shall be unregistered until <mode>=0 or 1 is
selected).
Read command returns the current mode and the currently selected operator. If no operator is
selected,<format> and <oper> are omitted.
Test command returns a list of quadruplets, each representing an operator present in the network.
Quadruplet consists of an integer indicating the availability of the operator <stat>, long and short
alphanumeric format of the name of the operator, and numeric format representation of the operator. Any of
the formats may be unavailable and should then be an empty field. The list of operators shall be in order:
home network, networks referenced in SIM, and other networks.

4.2.4 AT+CSSN Supplementary service notifications
This command refers to supplementary service related network initiated notifications. The set command
enables/disables the presentation of notification result codes from TA to TE.
When <n>=1 and a supplementary service notification is received after a mobile originated call setup,
intermediate result code +CSSI: <code1>[,<index>] is sent to TE before any other MO call setup result
codes presented in the present document. When several different <code1>s are received from the network,
each of them shall have its own +CSSI result code.
When <m>=1 and a supplementary service notification is received during a mobile terminated call setup or
during a call, or when a forward check supplementary service notification is received, unsolicited result
code +CSSU: <code2>[,<index>[,<number>,<type>[,<subaddr>,<satype>]]] is sent to TE. In case of MT
call setup, result code is sent after every +CLIP result code (refer command "Calling line identification
presentation +CLIP")and when several different <code2>s are received from the network, each of them
shall have its own +CSSU result code.
