Multi-Tech Systems, Inc. AT Commands for EDGE (E1) Modems (S000474A) 226
12.13 AT+CSCA SMS Service Center Address
Description: The write command updates the SMSC address, through which mobile originated SMs are
transmitted. In text mode, setting is used by send and write commands. In PDU mode, setting is
used by the same commands, but only when the length of the SMSC address coded into the
<pdu> parameter equals zero.
Syntax: Test Command: AT+CSCA=?
Response: OK
Read Command: AT+CSCA?
Response: +CSCA: <sca>, <tosca>
OK
Write Command: AT+CSCA=<sca>[, <tosca>]
Response: OK
Notes:
• In case of using no parameter after AT+CSCA= the content of <sca> will be deleted.
• This command writes the service center address to non-volatile memo.
• The SMS service center address should be entered as specified by the service provider.
• This command is PIN protected.
• This command is supported in airplane mode.
12.14 AT+CSCB Select Cell Broadcast Message Indication
Description: The test command returns supported modes as a compound value.
The write command selects which types of CBMs are to be received by the ME.
Syntax: Test Command: AT+CSCB=?
Response: +CSCB: (list of supported <mode>s)
OK
Read Command: AT+CSCB?
Response: +CSCB: <mode>, <mids>, <dcss>
OK
Write Command: AT+CSCB=<mode>[, <mids>[, <dcss>]]
Response: OK
Parameters:
<mode> Message mode
0 Accept messages that are defined in <mids> and <dcss>. Default. This is the factory default
value and can be restored to '0' with AT&F.
1 Forbid messages that are defined in <mids> and <dcss>
<mids> Cell Broadcast Message ID specification
" " Default value of this parameter is empty string, and it means that no CBM identifiers are
specified. This is the factory default value and can be restored to '" "' with AT&F. This is the
default value if the parameter is omitted (" " will be assumed).
• For <mode>=0: Six different possible combinations of CBM IDs (e.g., “0,1,5,320-
478,922,2000-3000”), default is empty string.
In certain configurations, such as using SIMs that contain data in Elementary File EF-CBMID
(Cell Broadcast Message Identifier for Data download), less than six combinations may be
available.
To access a SIM’s Elementary File data refer to command AT+CRSM.
• For <mode>=1: One CBM ID or range of IDs (e.g., “320-478”) default is empty string.
<dcss> CBM data coding scheme specification
““ Default value of this parameter is empty string. This is the factory default value and can be
restored to '" "' with AT&F. This is the default value if the parameter is omitted (" " will be
assumed).
All different possible combinations of CBM data coding schemes (e.g., “0-3,5”). Using default
empty string leads to get all CBMs independent of their dcss.
A given <dcss> replaces any former value and is used for consecutive requests.
Notes:
• This command is PIN protected.
• This command is supported in airplane mode.
