Definitions and Conventions
1. Definitions
For the purposes of the present document, the following syntactical definitions apply:
<CR> Carriage return character.
<LF> Linefeed character.
<…> Name enclosed in angle brackets is a syntactical element. Brackets themselves do not
appear in the command line.
[…] Optional subparameter of AT command or an optional part of TA information response is
enclosed in square brackets. Brackets themselves do not appear in the command line. If subparameter is not given, its value equals to its previous value or the recommended default value.
underline Underlined and defined subparameter value is the recommended default setting or
factory setting.
Parameter Saving Mode
NO_SAVE: The parameter of the current AT command will be lost if module is rebooted or current AT
command doesn't have parameter.
AUTO_SAVE: The parameter of the current AT command will be kept in NVRAM automatically and
take in effect immediately, and it won't be lost if module is rebooted.
AUTO_SAVE_REBOOT: The parameter of the current AT command will be kept in NVRAM
automatically and take in effect after reboot, and it won't be lost if module is rebooted.
AT&W_SAVE: The parameter of the current AT command will be kept inusersetting_save.nvm by
sending the command of "AT&W".Restore the previously saved value if module is rebooted by sending the command of "ATZ"
Max Response Time
Max response time is estimated maximum time to get response, the unit is seconds.
2. Document Conventions
Generally, the characters <CR> and <LF> are intentionally omitted throughout this document.

A7600 Series_AT Command Manual_V1.02
AT commands and responses in figures may be not following above conventions.
NOTE
If command response is ERROR, not list the ERROR response inside command syntax.
AT Interface Synopsis
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.
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 "<n>" is/are the parameter(s)for the basic command which is optional. An Examples of Basic Command is
www.simcom.com 24 / 440
Page 26
A7600 Series_AT Command Manual_V1.02
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
"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 the next AT Command.

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.

ATH Disconnect existing call
This command is used to disconnect existing call. Before using ATH command to hang up a voice call, it must set AT+CVHU=0. Otherwise, ATH command will be ignored and "OK" response is given only. This command is also used to disconnect PS data call, and in this case it doesn’t depend on the value of AT+CVHU.
Examples
ATS0 Automatic answer incoming call
The S-parameter command controls the automatic answering feature of the Module. If set to 000, automatic answering is disabled, otherwise it causes the Module to answer when the incoming call indication (RING)has occurred the number of times indicated by the specified value; and the setting will not be stored upon power-off, i.e. the default value will be restored after restart.

NOTE
+++ 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
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.

Test Command
Response
A7600 Series_AT Command Manual_V1.02
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.
It is recommended (although optional)that after the operator list TA returns lists of supported <mode>s and <format>s. These lists shall be delimited from the operator list by two commas.

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.

This command allows the TE to specify a Packet Filter - PF for a Traffic Flow Template - TFT that is used in the GGSN in UMTS/GPRS and Packet GW in EPS for routing of packets onto different QoS flows towards the TE. The concept is further described in the 3GPP TS 23.060 [47]. A TFT consists of from one and up to 15 Packet Filters, each identified by a unique <packet filter identifier>. A Packet Filter also has an <evaluation precedence index> that is unique within all TFTs associated with all PDP contexts that are associated with the same PDP address.
