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, intermediate result code +CSSI: <code1>[,<index>] is sent to TE before any other MO call
setup result codes presented in the present document. 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 terminated call
setup or during a call, or when a forward check supplementary service notification is received,
unsolicited result code +CSSU: <code2>[,<index>[,<number>,<type>[,<subaddr>,<satype>
]]] 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: This command not supported in CDMA/HDR mode.
