This command refers to supplementary service related network initiated
notifications. The set command enables or 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. 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>] 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.
Test command returns values supported by the TA as a compound value.
