Confidential / Draft - Do not copy

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 TC63 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 TC63 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

) 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 EF

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 TC63 has fin-

ished reading the phonebook.

Note that the settings of AT^SIND and AT+CMER will be restored to their default

values when restarting the TC63. Therefore it is recommended that the set-

tings be enabled before entering the SIM PIN. This can be done, for example,

after rebooting the TC63.
