• If <dcs> indicates that 8-bit or UCS2 data coding scheme is used: ME/TA converts each 8-bit octet into hexa-
decimal numbers containing two IRA characters.
Discharge Time
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"
Integer type; value in the range of location numbers supported by the asso ciated memory
Message Length
Integer type value indicating in the text mode (AT+CMGF=1) the length of the message body <data> (or
<cdata>) in characters; or in PDU mode (AT+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 m aximum length of an SMS
depends on the used coding scheme: It is 160 characters if the 7 bit GS M coding scheme is used, and 140 char-
acters according to the 8 bit GSM coding scheme.
If the SMS message format is ''text mode'' (AT+CMGF=1) and the character set is set to ''UCS2'' with AT+CSCS
and the SMS is also coded as "UCS2" (see <dcs> of AT+CSMP), then the length is in octets in stead of charac-
ters.
