“rssi“ Received signal (field) strength:
Received signal (field) strength can also be obtained with AT+CSQ. However,
the signal strength is scaled to value range 0..31 by this command.
“simdata“ USIM notifies of changed Elementary File data:
All data provided by the USIM is stored in one of many of its so-called Elemen-
tary Files.
Be aware that this Elementary File data can be changed at any time by the net-
work provider or an application running on the USIM.
Therefore, a "+CIEV: "simdata"" URC is issued if USIM sent a SAT REFRESH
command indicating that the content of one or more Elementary Files has been
changed.
“vmwait“ Message Waiting Indication. Indicates new message(s) waiting included in
User Data Header (UDH).
"vmwait" indicates the receipt of a special short message with a Message Wait-
ing Indicator. The service must be provisioned by the operator.
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 message is put into the mailbox. After the
subscriber has retrieved all 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, the number will be displayed by the EHS6 as
part of the URC. For example:
"+CIEV: vmwait,1,3,0,0,0" notifies that three new voice messages are waiting.
"+CIEV: vmwait,1,5,2,3,1" notifies that five new voice messages, two fax mes-
sages, three email messages and 1 other message 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), mail(s), fax or others via standard SMS. In this case the indicator "mes-
sage" will be displayed.
“ciphcall“ Ciphering Status Change Indication:
As stated in GSM specifications 02.07 and 02.09 the ciphering indicator feature
allows the EHS6 to detect that ciphering is not switched on and to indicate this
to the user.
The URCs +CIEV: ciphcall,0 or +CIEV: ciphcall,1 will show up when:
- a call is etablished,
- ciphering status changes during a call,
- an SMS is sent or received.
The URC will not be printed when the connection is released.
Read command AT^SIND? returns valid ciphering status only if a call is in
progress or active.
URC with ciphering status change indication appears only the interface on
which URC indication was enabled using AT^SIND.

messages.
