Confidential / Released
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
“ciphcall“ Ciphering Status Change Indication
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
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.
