Chapter 13 – Specific AT Commands
Multi-Tech Systems, Inc. Wireless GSM/GPRS AT Commands (Document Number S000293I) 109
Description: This command provides a general mechanism to send unsolicited non-standardized indications to the
application. The indicators are:
• Indication of a physical change on the SIM detect pin from the connector (meaning SIM inserted,
SIM removed)
• Indication during mobile originated call setup that the calling party is ringing.
• Indication of the availability of the product to receive AT commands after boot.
• NITZ indication (Network Information and Time Zone)
For each of these indications, a “bit flow” has to be indicated.
Values: <IndLevel>
0 No unsolicited “+WIND: <IndNb>” will occur. Default.
1 (bit-0) Hardware SIM Insert/Remove indications or SIM presence after software reset.
2 (bit-1) Calling party alert indication.
4 (bit-2) Product is ready to process AT commands (except phonebooks, AOC, SMS), but
still in emergency mode.
8 (bit-3) The product is ready to process all AT commands at the end of init or after
swapping to ADN in case of FDN configuration
16 (bit-4) A new call identifier has been created (after an ATD command, +CCWA indication)
32 (bit-5) An active, held or waiting call has been released by network or other party
64 (bit-6) Network service available indication
128 (bit-7) Network lost indication
256 (bit-8) Audio ON indication
512 (bit-9) SIM phonebooks reload status
1024 (bit-10) SIM phonebooks checksum indication
2048 (bit-11) Interruption indication (only if FTR_INT is activated)
4096 (bit-12) Hardware rack open/closed indication
8192 (bit-13) NITZ indication
16384 (bit-14) SMS service ready indication
Combination (addition of the values) is used to allow more than one indication flow: 0 ≤ IndLevel ≤
32767
• To activate a specific WIND indication, <IndLevel> must have a value described above.
AT+WIND=16384 only activates SMS service indication.
• To activate several WIND indications, <IndLevel> must have a value just before the last
indication required.
AT+WIND=32767 all unsolicited indications.
<event>
0 The SIM presence pin has been detected as “SIM removed”
1 The SIM presence pin has been detected as “SIM inserted”
2 Calling party is alerting

AT+CFUN=1
4 Product is ready to process all AT commands, end of phonebook init or swap (FDN to ADN)
5 Call <idx> has been created (after ATD or +CCWA…)
6 Call <idx> has been released, after a NO CARRIER, a +CSSU: 5 indication, or after the
release of a call waiting.
7: The network service is available for an emergency call.
8 The network is lost.

10 Show reload status of each SIM phonebook after init phase (after Power-ON or SIM
insertion).
11 Show the checksum of SIM phonebooks after loading.
