10.1 AT^SICS Internet Connection Setup Profile
Description: AT^SICS serves to create and edit Internet connection profiles. A connection profile can be
assigned to one or more service profiles defined with AT^SISS, and thus, determines which type
of connection is to be established when opening a service profile with AT^SISO.
The AT^SICS read command requests the current settings of all Internet connection profiles.
One line is issued for every possible parameter of a given <conParmTag> “conType” value.
The AT^SICS write command specifies all parameters of a connection profile identified by
<conProfileId>. At first, the type of Internet connection needs to be selected via <conParmTag>
value “conType”. This determines the applicability of all other <conParmTag> values related to
this “conType” and automatically sets their defaults. An exception to the <conParmValue-
alphabet> which can be set before or after selecting “con-Type”. To change the settings the write
command needs to be executed for each single <conParmTag>. All profile parameters set with
AT^SICS are volatile.

Parameters:
<conProfileId>
0...5 Internet connection profile identifier.
The <conProfileId> identifies all parameters of a connection profile, and, when a service profile is
created with AT^SISS the <conProfileId> needs to be set as “conId” value of the AT^SISS
parameter <srv-ParmTag>.
<conParmTag>
Internet connection parameter.
“conType“ Type of Internet connection.
For supported values of <conParmValue> refer to <conParmValue-con-Type>.
“alphabet“ Selects the character set for input and output of string parameters within a profile.
The selected value is bound to the specific profile. This means that different profiles
may use different alphabets. Unlike other parameters, the alphabet can be changed
whether or not <conParmTag> value “conType” has been set.
For supported values of <conParmValue> refer to <conParmValuealphabet>.
“user“ User name string: maximum 32 characters (where “” is default).
“passwd“ Password string: maximum 32 characters (where “” is default). If the <conParmValue-
authMode> is “MsChapV1”, then the maximum password length is 16 characters.
“apn“ Access point name string value: maximum 100 characters (where “” is default).
