Siemens MC55 AT Atsics Internet Connection Setup Profile, ConParmTag value, Atsics=?, Atsics?

10.1AT^SICS Internet Connection Setup Profile

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 deter- mines the applicability of all other <conParmTag> values related to this "conType" and automatically sets their defaults. An exception is 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.

MC55 supports the authentication methods PAP (Password Authentication Protocol), CHAP (Handshake Authentication Protocol) or none. The method actually used for an Internet connection via CSD or GPRS is nego- tiated at the LCP layer, i.e. it is negotiated with the remote peer at connection setup.
