19.14 AT+CSSN Supplementary Service Notification
This command refers to supplementary service related network initiated
notifications. The set command enables/disables the presentation of
notification result codes from TA to TE.
When <n>=1 and a supplementary service notification is received after
a mobile originated call setup, unsolicited result code +CSSI:
<code1>[,<index>] is sent to TE before any other MO call setup result
codes presented in this ETS or in V.25ter [13]. When several different
<code1>s are received from the network, each of them shall have its
own +CSSI result code.
When <m>=1 and a supplementary service notification is received
during a mobile terminatedcall setup or during a call, or when a forward
check supplementary service notification is received, unsolicited result
code +CSSU: <code2>[,<index>] is sent to TE. In case of MT call
setup, result code is sent after every +CLIP result code (refer command
"Calling line identification presentation +CLIP") and when several
different <code2>s are received from the network, each of them shall
have its own +CSSU result code.
Note! The difference between <index> and <cindex> is that <index> is a
position mark while <cindex> is a unique value for each CUG. <index>
is not supported.
