MC55 AT Command Set

3.3 AT^SIND

Command Description

s

mobile

The read command provides a list of all indicators supported by AT+CIND and AT^SIND. Each indicator is rep- resented with its registration mode and current value.

The write command can be used to select a single indicator in order to modify its registration and to view the current value.

Parameter Description

<indValue>(num)

Integer type value in the range stated below for the corresponding <indDescr>

<indDescr>(str)

String values and their <indValue> ranges.

All indicators supported by AT+CIND are accessible with this command, too. A detailed description of these indi- cators can be found there.

The following indicators are accessible via AT^SIND only:

“audio“	Activity of the internal audio unit (0-1). Value 1 means for example:
	Outgoing voice call: Indicator appears when dialing starts.
	Incoming voice call: Indicator appears prior to the RING result code.
“vmwait1“	Voice message waiting indication for line 1, (0-1)
“vmwait2“	Voice message waiting indication for line 2, (0-1)
“ciphcall“	Ciphering Status Change Indication
	As stated in GSM specifications 02.07 and 02.09 the ciphering indicator feature
	allows the ME to detect that ciphering is not switched on and to indicate this to
	the user.
	The ciphering indicator feature may be disabled by the home network operator
	setting data in the "administrative data" field (EFAD) in the SIM, as defined in
	GSM 11.11.
	If this feature is not disabled by the SIM, then whenever a connection is in
	place, which is, or becomes unenciphered, an indication shall be given to the
	user. This enables the user's decision how to proceed.
	Read command returns valid ciphering status only if a call is in progress or
	active.
	If EFADsetting disables the ciphering indicator feature read command always
	indicates a ciphered link and no URC presentaion will take place.
	Note:
	The following restrictions apply if the same serial channel is used for AT^SIND
	"ciphcall" indication and for the action triggering this URC. In general, the rec-
	ommended solution is to use a dedicated channel for all status signalling via
	URCs.
	• If an unciphered mobile originated SMS is performed, AT^SIND "ciphcall"
	URCs on the same serial channel will be issued after the related "OK" and
	indicate the ciphering state at this time. Because the SMS is already sent at
	this time, you will get 2 URCs on this channel, but both are indicating that
	ciphering is enabled.
	• If an unciphered mobile originated data call is performed, AT^SIND "ciph-
	call" URCs on the same serial channel will be issued after the interface is
	not longer blocked by the call (call is released or temporarily stopped) and
	indicate the ciphering state at this time.

0	.. Current call or SMS is not ciphered.
1	.. Current call or SMS is ciphered.
