What is a syntax of AT+CUSD ?

[darius2]

Hi,

please tell me, what is a full syntax of AT+CUSD command
for sending balance check request
like this
AT+CUSD=1,"*111#",15

The last parameter stays for what and what options are available ?

Have a look at 3GPP technical specification 27.007.

thanks,

what I mean is, what set of values <dsc> can assume,
so <dsc> = 15 in
the following examples
AT+CUSD=0,"*111#",15
stays for what and why "15" and not "0" or no <dcs> at all ?


==
- if <dcs> indicates that 3GPP TS 23.038 [25] 7 bit default alphabet is used:
- if TE character set other than "HEX" (refer command Select TE Character Set +CSCS): MT/TA
converts GSM alphabet into current TE character set according to rules of 3GPP TS 27.005 [24]
Annex A
- if TE character set is "HEX": MT/TA converts each 7-bit character of GSM alphabet into two IRA
character long hexadecimal number (e.g. character Π (GSM 23) is presented as 17 (IRA 49 and 55))
- if <dcs> indicates that 8-bit data coding scheme is used: MT/TA converts each 8-bit octet into two IRA
character long hexadecimal number (e.g. octet with integer value 42 is presented to TE as two characters
2A (IRA 50 and 65))
<dcs>: 3GPP TS 23.038 [25] Cell Broadcast Data Coding Scheme in integer format (default 0)
