MC35i AT Command Set

MC35i AT Command Set3.3 AT^SINDParameter Description(str)String values and their ranges.All indicators supported by AT+CIND are accessible with this command, too. A detailed description of these indicatorscan be found there.The following indicators are accessible via AT^SIND only:"netlost"Indication of status change in GSM network coverage0 Network registration or location update succeeded.1 Network registration or location update failed because of bad uplinkconnection."ciphcall"Ciphering Status Change Indication0 Current call or SMS is not ciphered.1 Current call or SMS is ciphered.As stated in GSM specifications 02.07 and 02.09 the ciphering indicator featureallows the MC35i to detect that ciphering is not switched on and to indicate thisto the user.The ciphering indicator feature may be disabled by the home network operatorsetting data in the "administrative data" field (EF AD ) in the SIM, as defined inGSM 11.11.If this feature is not disabled by the SIM, then whenever a connection is inplace, which is, or becomes unenciphered, an indication shall be given to theuser. This enables the user's decision how to proceed.Read command returns valid ciphering status only if a call is in progress oractive.If EF AD setting disables the ciphering indicator feature read command alwaysindicates 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 recommendedsolution is to use a dedicated channel for all status signalling viaURCs.• If an unciphered mobile originated SMS is performed, AT^SIND "ciphcall"URCs on the same serial channel will be issued after the related "OK" andindicate the ciphering state at this time. Because the SMS is already sent atthis time, two URCs will be issued on this channel, but both are indicatingthat ciphering is enabled.• If an unciphered mobile originated data call is performed, AT^SIND "ciphcall"URCs on the same serial channel will be issued after the interface isnot longer blocked by the call (call is released or temporarily stopped) andindicate the ciphering state at this time. (num)Integer type value in the range stated above for the corresponding . (num) 9/10/080 Indicator is deregistered, i.e. no such indicator event report (URC) will beissued. =0 is power-up and factory default of indicators defined byAT^SIND only.1 Indicator is registered.• Indicator event reports are controlled via AT+CMER.• All indicators can be registered or deregistered via AT^SIND, but differentdefault settings apply: Power-up and factory default of the indicators supportedby AT+CIND is =1, while, as stated above, indicators definedby AT^SIND only are set to =0.2 Query the registration status and the current value of a single indicator type.MC35i_ATC_V02.00nConfidential / ReleasedPage 61 of 390
