Confidential / Released

"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

.

Supported connection type values in

for

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.

Character set selectable with

for

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

for

value "dataType".

"0"

ISDN

["1"]

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

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

?.
