and <ci> are returned only when <n>=2 and A3LA-RG is registered in the network. Response

is in the form:

+CREG: <n>,<stat>[,<lac>,<ci>]

Test Command: +CREG=?

Test command lists the supported settings for +CREG. Response is in the form:

+CREG: (list of supported <n>s)

A.8.51 +CSCA – SMS Service Center Address

Set Command: +CSCA=<sca>[,<tosca>]
Set command updates the SMSC address, through which mobile originated SMs are
transmitted. In PDU mode, setting is used by the send and write commands, but only when the
length of the SMSC address coded into <pdu> parameter equals zero.

<sca>: GSM 04.11 [8] RP SC address Address-Value field in string format (i.e., enclosed by

quotes ““);

<tosca>: GSM 04.11 [8] RP SC address Type-of-Address octet in integer format;

Read Command: +CSCA?

Read command returns the current service center address. Response is in the form:

+CSCA: <sca>,<tosca>

A.8.52 +CSCB – Select Cell Broadcast Message Types

Read Command: +CSCB?
Read command returns the current values for <mode>, <mids> and <dcss>. Response is in

the form:

+CSCB: <mode>,<mids>,<dcss>

Test Command: +CSCB=?
Test command returns supported modes. Response is in the form:

+CSCB: (list of supported <mode>s)

A.8.53 +CSCS – Select TE Character Set

Set Command: +CSCS=[<chset>]

Set command informs the A3LA-RG which character set <chset> is used by the DTE. Only the
IRA character set is currently supported. <chset> should be of string type enclosed by ““; for
example, “IRA”.

Valid values for <chset> are: "IRA" international reference alphabet (ITU-T T.50)

Read Command: +CSCS?
Read command returns the current character set used. Response is in the form:

+CSCS: <chset>

Test Command: +CSCS=?

Test command returns the supported character set of the A3LA-RG. Response is in the form:

+CSCS: (list of supported <chset>s)
