AT Command Set for Nokia 8850
+CRING: <type>
is given when +CRC=1 and incoming MT call (no active or held calls in ME).
Note that this code replaces the V.25ter RING result code. (GSM 07.07 section 6.11).
+CSSI: <code1>[,<index>]
is given when +CSSN=1 and some supplementary service notification is given by
network during MO call establishment.
This is the first intermediate result code after dial command D. Supported <code1>'s
depend on the supplementary services implemented in a product. (GSM 07.07
section 7.2).
+CSSU: <code2>[,<index>[,<number>, <type>[,<saddr>,<satype>]]]
is given when +CSSN=,1 and some supplementary service notification is given by
network during MT call setup or during a voice call; note that also remote release of a
held call is informed with this result code.
In MT call setup case, this result code is sent to TE after every (possible) +CLIP
result code. In case of a waiting call, this is given after +CCWA result code (but
discarded if TA is in on-line data state and V.80 in-band mode is disabled or not
supported). Supported <code2>'s depend on the supplementary services
implemented in a product. (GSM 07.07 section 7.16).
+CUSD: <m>,<str>,<dcs>
is given when +CUSD=1 and network initiated 'notify' or 'request' USSD message
received; discarded if in on-line data state (also when V.80 in-band mode is enabled).
Note that only the first 'request' message during a network initiated USSD session
yields to this unsolicited result code. Rest are information responses of +CUSD
command. (GSM 07.07 section 7.14).
