<ct> GSM 03.40 TP-Command-Type in integer format (default 0)
<da> GSM 03.40 TP- Destination-Address Address-Value field in s tring format;
BCD numbers (or GSM default alphabet characters) are converted into cha-
racters; type of address given by <toda>
<data>
In case of SMS: GSM 03.40 TP-User-Data in text mode responses; format:
-if <dcs> indicates that GSM 03.38 default alphabet is used and <f o> indi-
cates that GSM 03.40 TP-User-Data-Header-Indication is not set:
ME/TA converts GSM alphabet into current TE character set ac-
cording to rules covered in Annex A
-if <dcs> indicates that 8-bit or UCS2 data coding scheme is used, or <fo>
indicates that GSM 03.40 TP-User-Data-Header-Indication is set:
ME/TA converts each 8-bit octet into hexadecimal numbers contain-
ing two IRA characters (e.g. octet with integer value 42 is presented
to TE as two characters 2A (IRA 50 and 65)
<dcs> depending on the command or result code: GSM 03.38 SMS Data Cod-
ing Scheme (default 0), or Cell Broadcast Data Coding Scheme in int e-
ger format
<cdata> GSM 03.40 TP-Command-Data in text mode responses; ME/TA con-
verts each 8-bit octet into two IRA character long hexadecimal numbers
(e.g. octet with integer value 42 is presented to TE as two characters 2 A
(IRA 50 and 65))
<dt> GSM 03.40 TP-Discharge-Time in time-string format: ”yy/MM/
dd,hh:mm:ss±zz”, where characters indicate year (two last digits),
month, day, hour, minutes, seconds and time zone. For example, 6th of
May 1994, 22:10:00 GMT+2 hours equals ”94/05/06,22:10:00+08”
<fo> depending on the command or result code: first octet of GSM 03.40
SMS- DELIVER, SMS-SUBMIT (default 17), SMS-STATUS- REPORT,
or SMS-COMMAND (default 2) in integer format
<length> integer type value indic ating in text mode (+CMGF=1) the length of the
message body <data> (or <cdata>) in characters; or in PDU mode
(+CMGF=0), the length of the actual TP data unit in octets (i.e. the RP
layer SMSC address octets are not counted in the length).
In text mode, the maximum length of an SMS depends on the used cod-
ing scheme: It is 160 characters if the 7 bit GSM coding scheme is used,
and 140 characters according to the 8 bit GSM coding scheme.
<index> integer type; value in the range of location numbers supported by the
associated memory
<mr> GSM 03.40 TP-Message-Reference in integer format
<oa> GSM 03.40 TP-Originating-Address Address-Value field in string for-
mat; BCD numbers (or GSM default alphabet characters) are converted
into characters; type of address given by <tooa>
<pdu> In the case of SMS: GSM 04.11 SC address followed b y GSM 03.40
TPDU in hexadecimal format: ME/TA converts each octet of TP data unit
into hexadecimal numbers containing two IRA characters (e.g. octet with
integer value 42 is presented to TE as two characters 2A (IR A 50 and
65)). In the case of CBS: <ra> GSM 03.40 TP-Recipient-Address Ad-
dress-Value field in string format; BCD numbers (or GSM default alph a-
bet characters) are converted into characters; type of address g iven by
<tora>
