"vmwait1" Voice Message Waiting Indication for line 1
"vmwait1" and "vmwait2" indicate the receipt of a special short message with a Voice
Message Waiting Indicator. The service must be provisioned by the operator.
The numbers 1 or 2 in "vmwait1" and "vmwait2" are related to the two lines of the Alternate
Line Service (ALS), also defined in CPHS Phase 2 standard. For further details refer to the
AT^SALS command.
The presentation mode of the indicator varies with the operator: If more than one message
are waiting, some operators only indicate the first one, others deliver the indicator each time
a new voice message is put into the mailbox.
After the subscriber has retrieved all voice messages the service center automatically 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, this number will be displayed by the Multi-Tech wireless modem 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 command 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
Multi-Tech wireless modem 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 (EF
If this feature is not disabled by the SIM, then whenever a connection is in place or is not
enciphered, an indication shall be given to the user. This enables the user's decision how to
proceed.

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 recommended
solution is to use a dedicated channel for all status signaling via URCs.
"adnread" Abbreviated Dialing Number (ADN) Phonebook Read Indication
0
1
Every time after entering the AT+CPIN the module starts reading the AND 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 the EDGE modem has finished reading the
phonebook.
Note that the settings of AT^SIND and AT+CMER will be restored to their default values
when restarting. Therefore it is recommended that the settings be enabled before entering
the SIM PIN. This can be done, for example, after rebooting.
