11.16 AT*ECPI Ciphering Indicator
This command allows the external application to activate/deactivate the
ciphering indication. The ciphering indication allows the external
application to detect when the mobile connection becomes deciphered
and thus unsecured.
Test command gives the current value of the <switch> parameter,
informing if the indicator is enabled or disabled.
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 deciphered, an indication is given via the
unsolicited result code *ECPV:<ciphering>.
Unsolicited Result Codes:
*ECPV: <ciphering>. Sent only when <switch> is set to 0.
