Set

+CSSN=[<n>[,<m>]]

OK

The Set command enables/disables the

 

 

+CME ERROR: <err>

display of notification result codes to

 

 

 

the TE.

 

 

 

When <n>=1 and a supplementary

 

 

 

service notification is received after a

 

 

 

mobile-originated call setup, the

 

 

 

+CSSI: notification is sent to the TE

 

 

 

before any other mobile-originated call

 

 

 

setup result codes. When several

 

 

 

different notifications are received

 

 

 

from the network, each of them

 

 

 

receives 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, the unsolicited result code

 

 

 

+CSSU: is sent to the TE. In case of a

 

 

 

mobile-terminated call setup, a CSSU

 

 

 

is sent after every +CLIP result code

 

 

 

(“+CLIP, Calling Line Identification”

 

 

 

on page 3-19). When several different

 

 

 

events are received from the network,

 

 

 

each of them receives its own +CSSU

 

 

 

result code.

 

 

 

Note: The values for <n> and <m>

 

 

 

are not saved after power

 

 

 

cycle.

notification setting.

The Test command displays the list of
