3.3 Global behaviour

3.3.1 SIM Insertion, SIM Removal
SIM card Insertion and Removal procedures are supported. These are software functions based on the reading of the hardware SIM presence pin. This pin state (open/closed) is continuously watched. When the SIM presence pin indicates a presence of "somewhat" in the SIM connector, the module tries to establish a SIM logical session. Depending if the "somewhat" is a SIM Card or not, the SIM logical session will be successfully established or not. The AT+CPIN? command delivers the following answers: If the SIM presence pin indicates "nothing", the answer to AT+CPIN? is "+CME ERROR: 10" (SIM not inserted). If the SIM presence pin indicates "something" and the inserted Card is a valid SIM Card, the answer to AT+CPIN? is "+CPIN: xxx" depending of the SIM PIN state. If the SIM presence pin indicates "something" and the inserted Card is not a valid SIM Card, the answer to AT+CPIN? is "CME ERROR: 10". These both last status are not immediately available after powering-up due to the background initialisation. During this step and before the SIM presence pin indicates "somewhat", the AT+CPIN? command returns "+CME ERROR: 515" (Please wait, initialisation in progress).
When the SIM presence pin indicates "nothing" and the previously inserted SIM Card was removed, an IMSI detach procedure is executed, and all the user data corresponding to this previous SIM are removed from the memory (Phonebooks, SMS etc.). The modem can then still emit calls but only in the emergency mode (only emergency numbers can be dialled).

Defined Values <mode>: 0: Deactivate Echo 1: Activate Echo 2: Configure the echo cancelation (automatically stored in E2P) <Taps>: Number of taps of the adaptive filter. This value is directly related to the length of the longest echo path (240 words = 30 ms echo path delay). Values from 1 to 192, default is 160 <ConvTh>: Threshold for convergence parameter. This specifies the level of energy computed on <EcDelay> samples needed to assume algorithm convergence. A low value provides a high convergence and a high value a high stability. Values from 0 to 45, default is 12. <DbtS>: Double talk sensitivity. This reflect the ratio between received and sent energy to assume double talk occured. A low value provides a high sensibility and a high value a low one. Values from 0 to 10, default is 5. <FarS>: Far end speaker detection - algorithm adaptation. This is related to then energy level needed on the receive path to allow filter taps adaptation. If <FarS> = 0 the algorithm will always adjust the filter. Values from 0 to 1000, default is 512. <EcDelay>: Number of samples used to compute energy for algorithm convergence evaluation. Values from 1 to 30, default is 10

4.9 V24-V25 commands

4.9.1 Fixed DTE rate +IPR
This commands specifies the data rate at which the DCE will accept commands. AT+IPR? +IPR: 9600 current rate is 9600 bps OK AT+IPR=? possible values (1) +IPR:(0,2400, 4800, 9600, 19200) , (300,600,38400,57600,115200) OK AT+IPR=38400 OK disable autobauding and set rate to 38400 bps AT+IPR=0 OK enable autobauding Note (1): first set of values indicates the range of autodetectable speeds. The second set of values indicates all the possible speeds which can be used by DCE. An autobauding is provided which operates from 2400 to 19200 baud. However some constraints have to be dealt with: any AT command issued by DTE must start with a capital A and T (or \). If not, DCE may send back some garbagge characters and get de-synchronized. Shoud it happen, DTE shall just issue once or twice AT\r (at 2400 or 4800 baud) or just AT (at 9600 baud) to get the modem re-synchronized. the DTE shall wait for 1ms after receipt of the last character of the AT response (which is always \n or 0x0A) to send a new AT command at either the same rate or a new rate. Shoud this delay ignored, DCE can get de-synchronised. Once again, sending once or twice AT\r or just AT causes the DCE to recover. Be careful: at start-up if autobauding is enabled and no AT command has been received yet, the module sends all unsolicited responses (like RING) at 9600 baud.

All other values in the range 0 to 31 shall be treated as cause 31. All other values in the range 32 to 47 shall be treated as cause 47. All other values in the range 48 to 63 shall be treated as cause 63. All other values in the range 64 to 79 shall be treated as cause 79. All other values in the range 80 to 95 shall be treated as cause 95. All other values in the range 96 to 111 shall be treated as cause 111. All other values in the range 112 to 127 shall be treated as cause 127.
6.5 GSM 04.11 Annex E-2: Mobile originating SM-transfer
These error causes could appear for SMS commands (+CMGS, +CMSS, +CMGD) Cause no 1: "Unassigned (unallocated) number" This cause indicates that the destination requested by the Mobile Station cannot be reached because, although the number is in a valid format, it is not currently assigned (allocated). Cause no 8: "Operator determined barring" This cause indicates that the MS has tried to send a mobile originating short message when the MS's network operator or service provider has forbidden such transactions. Cause no 10: "Call barred" This cause indicates that the outgoing call barred service applies to the short message service for the called destination. Cause no 21: "Short message transfer rejected" This cause indicates that the equipment sending this cause does not wish to accept this short message, although it could have accepted the short message since the equipment sending this cause is neither busy nor incompatible. Cause no 27: "Destination out of service" This cause indicates that the destination indicated by the Mobile Station cannot be reached because the interface to the destination is not functioning correctly. The term "not functioning correctly" indicates that a signalling message was unable to be delivered to the remote user; e.g., a physical layer or data link layer failure at the remote user, user equipment off-line, etc. Cause no 28: "Unidentified subscriber" This cause indicates that the subscriber is not registered in the PLMN (i.e. IMSI not known) Cause no 29: "Facility rejected" This cause indicates that the facility requested by the Mobile Station is not supported by the PLMN. Cause no 30: "Unknown subscriber" This cause indicates that the subscriber is not registered in the HLR (i.e. IMSI or directory number is not allocated to a subscriber). Cause no 38: "Network out of order" This cause indicates that the network is not functioning correctly and that the condition is likely to last a relatively long period of time; e.g., immediately reattempting the short message transfer is not likely to be successful. Cause no 41: "Temporary failure" This cause indicates that the network is not functioning correctly and that the condition is not likely to last a long period of time; e.g., the Mobile Station may wish to try another short message transfer attempt almost immediately. Cause no 42: "Congestion" This cause indicates that the short message service cannot be serviced because of high traffic. Cause no 47: "Resources unavailable, unspecified" This cause is used to report a resource unavailable event only when no other cause applies. Cause no 69: "Requested facility not implemented" This cause indicates that the network is unable to provide the requested short message service. Cause no 81: "Invalid short message transfer reference value" This cause indicates that the equipment sending this cause has received a message with a short message reference which is not currently in use on the MS-network interface. Cause no 95: "Invalid message, unspecified" This cause is used to report an invalid message event only when no other cause in the invalid message class applies.

Cause no 96: "Invalid mandatory information" This cause indicates that the equipment sending this cause has received a message where a mandatory information element is missing and/or has a content error (the two cases are undistinguishable). Cause no 97: "Message type non-existent or not implemented" This cause indicates that the equipment sending this cause has received a message with a message type it does not recognize either because this is a message not defined or defined but not implemented by the equipment sending this cause. Cause no 98: "Message not compatible with short message protocol state" This cause indicates that the equipment sending this cause has received a message such that the procedures do not indicate that this is a permissible message to receive while in the short message transfer state. Cause no 99: "Information element non-existent or not implemented" This cause indicates that the equipment sending this cause has received a message which includes information elements not recognized because the information element identifier is not defined or it is defined but not implemented by the equipment sending the cause. However, the information element is not required to be present in the message in order for the equipment sending the cause to process the message. Cause no 111: "Protocol error, unspecified" This cause is used to report a protocol error event only when no other cause applies. Cause no 127: "Interworking, unspecified" This cause indicates that there has been interworking with a network which does not provide causes for actions it takes; thus, the precise cause for a message which is being send cannot be ascertained. All values other than specified should be treated as error Cause No 41
