Chapter 3 – Status Control Commands “call“ Call in progress (0-1). Indicator value is “1” if at least one call is in state “active” or “held”. Depending on the parameter selected with AT^SCFG the indicator “call” will be issued • when a state transition ends in state “active” or state “unknown”, if =”restricted”, • when any state transition (including transitions beginning or ending in state “unknown”) occurs in the list of active calls or when a traffic channel is established, if =”verbose”. Also refer to Section 7.1, Call Status Information. “roam“ Roaming indicator (0-1) 0: Registered to home network or not registered “smsfull“ 1: Registered to other network A short message memory storage in the MT has become full (1) or memory locations are available (0); i.e., range is (0-1) “rssi“ Received signal (field) strength (0..5). 0: signal strength = -51 dbm 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. 0 Indicator is deregistered. The indicator will not be presented as “+CIEV” URC, but can be queried with AT+CIND. 1 Indicator is registered, indicator event report allowed. Default. This is also the powerup default of this parameter; it is not stored at power down. Notes: • Due to its restrictive value range, indicator “call” does not clearly reflect specific call states (such as alerting, active, held etc.), but rather serves to trigger the application to retrieve the new call status from the list of current calls with the AT commands AT^SLCC, AT+CLCC or AT^SCNI. • If AT^SCFG setting =”verbose”, indicator “call” will be issued also when a traffic channel is established, or when a call enters states “terminating” or “dropped” (see Call Status Information). In these cases, the relevant information about the cause of the display is available only from AT command AT^SLCC. Examples Example 1 ^SYSSTART AT+CPIN=9999 OK AT+CIND +CIND: 5,1,0,0,0,0,0 OK AT+CMER=2,0,0,2 OK +CIEV: battchg,5 +CIEV: service,1 +CIEV: sounder,0 +CIEV: message,0 +CIEV: call,0 +CIEV: roam,0 +CIEV: smsfull,0 +CIEV: rssi,5 ATD0123456; OK +CIEV: sounder,1 +CIEV: call,1 +CIEV: sounder,0 +CIEV: call,0 NO CARRIER AT+CIND=,,,0,,0 OK ATD0123456; OK NO CARRIER Example 2 Deactivation of indicator “sounder” via AT+CIND AT+CIND= Query the current status of indicators. +CIND: 5,1,0,1,0,0,0,4 OK AT+CIND=,,,0 OK Example 3 Deactivation of indicator “sounder” via AT^SIND AT^SIND=”sounder”,0 ^SIND: sounder,0,0 OK The battery is either full or no battery is connected to the ME. The bit error rate of the signal quality is not available (since there is no call in progress). The ME is registered to its home network. Now activate the Indicator Event Report with AT+CMER. Full receive signal strength. Make a call. A set of “+CIEV” URCs is received. Called party hangs up. Deregister the indicators “sounder” and “call”. Dial the same call. This time, no URCs are displayed. Called party hangs up. To deactivate indicator “sounder” (= fourth item in list of indicators). To deactivate indicator “sounder”. Multi-Tech Systems, Inc.

Chapter 3 – Status Control Commands 3.3 AT^SIND Extended Indicator Control Description: Designed for extended event indicator control AT^SIND • offers greater flexibility than the standard command AT+CIND, • offers several extra indicators, • can show the current status of all indicators supported by AT+CIND and AT^SIND, • can be used to register or deregister the indicators of both commands, • displays all indicator event reports via “+CIEV” URCs. Presentation mode of the generated URCs is controlled via AT+CMER. The AT^SIND read command provides a list of all indicators supported by AT+CIND and AT^SIND. Each indicator is represented with its registration mode and current value. The AT^SIND write command can be used to select a single indicator in order to modify its registration and to view the current value.

URC 2 Format of the Voice Message indicator, if the number of waiting messages is delivered by the network: +CIEV: , , If the number of waiting messages is not delivered the standard indicator applies. URC 3 Format of the “eons” indicator +CIEV: , , , One URC is issued for each new LAI (Location Area Information) broadcast by the network. URC 4 Format of the “nitz” indicator: +CIEV: , , , URC 5 Format of the “msclass” indicator: +CIEV: , Parameter Descriptions: String values and their ranges. All indicators supported by AT+CIND are accessible with this command, too. A detailed description of these indicators can be found there. The following indicators are accessible via AT^SIND only: “audio“ Activity of the built-in audio unit. 0 Audio unit not active. 1 Value 1 means for example: Outgoing voice call: Indicator appears when dialing starts. Incoming voice call: Indicator appears prior to the RING result code. Multi-Tech Systems, Inc. AT Commands for EDGE Modems (S000371B) 39
