Siemens MC55 AT manual Example Default values of a CSD connection profile, ProfileId1

"dns2"	Secondary DNS server address (IP address in dotted-four-byte format).
	If "dns1" = "0.0.0.0" this setting will be ignored. Otherwise this value can be
	used to manually configure an alternate server for the DNS1.
	If "dns1" is not equal "0.0.0.0" and no "dns2" address is given, then
	"dns2"="0.0.0.0" will be assumed automatically. The AT^SICS read command
	only returns a manually configured IP address, while the value "0.0.0.0" is not
	indicated at all, no matter whether assumed by default or explicitly specified.

<conParmValue>(str)

Parameter value; type and supported content depend on related <conParmTag>.

<conParmValue-conType>(str)

Supported connection type values in <conParmValue> for <conParmTag> value "conType".

"CSD"	Circuit-switched data call.
"GPRS0"	GPRS connection.
	Settings of GPRS related commands are not used, e.g. AT+CGDCONT. When a
	service based on a GPRS connection profile is started after entering AT^SISO
	MC55 automatically tries to attach to the GPRS. Yet, the only exception is
	AT+CGATT which can be used any time to detach from the GPRS and, and thus
	disconnect the bearer opened with AT^SISO.
"none"	Clears the connection profile.

<conParmValue-alphabet>(str)

Character set selectable with <conParmValue> for <conParmTag> value "alphabet".

["0"]	Character set determined with AT+CSCS applies.
"1"	International Reference Alphabet (IRA, seven bit ASCII) applies.

<conParmValue-dataType>(str)

Supported data call type values in <conParmValue> for <conParmTag> value "dataType".

"0"	ISDN
["1"]	Analog

Notes

•Before opening a service profile based on a connection profile recently used, check with AT^SICI that the previous connection was properly closed. If AT^SICI confirms that the connection profile is in <conState> 0 (Down) the connection profile may be used again.

•If a GPRS network does not support or is not correctly configured for automatic DNS address assignment the TCP/IP stack cannot resolve fully qualified domain names. In this case, a warning message will be returned when trying to open an Internet service configured for automatic DNS address assignment.

10.1.1Example: Default values of a CSD connection profile

As stated earlier, the "conType" selected with AT^SICS determines all other matching profile parameters related to this "conType". Once "conType" is set in a new profile, the default values of all other related parameters are assumed. To view the default settings you can use the read command AT^SICS?.

	at^sics=1,conType,CSD		Select connection type CSD, identified by <con-
			ProfileId>1
	OK		Query current profiles.
	at^sics?
	^SICS: 0, "conType", ""		Profile with <conProfileId> 0 is still empty.
