AC75 AT Command Set

3.3 AT^SIND

s

After the subscriber has retrieved all voice messages the service center auto- matically sends another message indication which provides the value 0. Some operators may also send the number of waiting voice messages along with the indication. In this case, the number will be displayed by the AC75 as part of the URC. For example, "+CIEV: vmwait1,1,5" notifies that five new voice messages are waiting. However, it should be noted that neither the read com- mand AT^SIND? nor the write command AT^SIND=<mode>,2 display the number of waiting messages.

The "vmwait" indicators do not apply if a network provider signals new voice mail(s) via standard SMS. In this case the indicator "message" will be displayed (see AT+CIND).

	“vmwait2“	Voice Message Waiting Indication for line 2
		0	See description of "vmwait1".
		1	See description of "vmwait1".
	“ciphcall“	Ciphering Status Change Indication
		0	Current call or SMS is not ciphered.
		1	Current call or SMS is ciphered.
		As stated in GSM specifications 02.07 and 02.09 the ciphering indicator feature
		allows the AC75 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 EFAD setting disables the ciphering indicator feature read command always
		indicates a ciphered link and no URC presentaion will take place.
		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.
		• 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.
	“adnread“	Abbreviated Dialing Number (ADN) Phonebook Read Indication
		0	Phonebook reading is not finished.
		1	Phonebook reading is finished.
		Every time after entering the AT+CPIN the module starts reading the ADN
		phonebook. This can be used to enable the TE to output the phonebook
		records as URCs. The advantage is that the user does not need to wait until
		the phonebook read command AT+CPBR is accessible after entering the SIM
		PIN (depending on the SIM card this may take up to 30 seconds without RSA
		or 2 minutes with RSA).
		If <mode>=1 all used ADN phonebook records stored on the SIM will be output
		as URCs after SIM PIN authentication has been performed successfully. A
		URC with "READY" tag issued at the end of the list indicates that AC75 has
		finished reading the phonebook.
		Note that the settings of AT^SIND and AT+CMER will be restored to their default
		values when restarting the AC75. Therefore it is recommended that the set-
		tings be enabled before entering the SIM PIN. This can be done, for example,
		after rebooting the AC75.
