BGS2T AT Command Set
10.1 AT^SICS

c
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.
See also note below.
“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.
Parameter value; type and supported content depend on related <conParmTag>.
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
BGS2T 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 thus dis-
connect the bearer opened with AT^SISO.
“none“ Clears the connection profile.
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.
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.
10.1.1 Example: 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?.
