[. . . ] 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. This reflect the ratio between received and sent energy to assume double talk occured. This is related to then energy level needed on the receive path to allow filter taps adaptation. <EcDelay>: Number of samples used to compute energy for algorithm convergence evaluation. Values from 1 to 30, default is 10 4. 2. 13 SideTone modification +SIDET Command syntax: AT+SIDET=<val1>, <val2> This specific command is used to get an echo of the voice in the speaker (to hear what is said in the speaker). <val2> 0 1 2 3 Application to GSM GSM to application Application to GSM GSM to application Level 0 db - 6 db -12 db -18 db <val1> 0 1 presence SideTone is disabled SideTone is enabled AT+SIDET=1, 0 OK AT+SIDET?+SIDET: 1, 0 OK Command valid Current value Command valid WAVECOM confidential © 34 WMO2 G900 / G1800 / G1900 WCOM/GSM/WMO2/WMO2ATDOC Friday 21 May 1999 4. 3 Network service related commands 4. 3. 1 Signal Quality +CSQ This command shall be used to know the received signal strength indication (<rssi>) and the channel bit error rate (<ber>) with or without any SIM card inserted. <rssi>: 0 : -113 dBm or less 1 : -111 dBm 2. . . 30 : -109 to -53 dBm 31 : -51dBm or greater 99 : not known or not detectable <ber>: 0. . . 7 : as RXQUAL values in the table GSM 05. 08 99 : not known or not detectable Application to GSM GSM to application AT+CSQ +CSQ: <rssi>, <ber> OK <rssi> and <ber> as defined above WAVECOM confidential © 35 WMO2 G900 / G1800 / G1900 WCOM/GSM/WMO2/WMO2ATDOC Friday 21 May 1999 4. 3. 2 Operator selection +COPS To select the operator, three possibilities exist: 1- The mobile enters the manual mode, and then try to find an operator which is indicated by the application. If it finds and registers correctly, then the mobile stays in idle mode. 2- The mobile enters the automatic mode, and then try to find the home operator. If it finds and registers correctly, then the mobile stays in idle mode ; if not, the mobile search automatically another network. 3- The mobile enters the manual/automatic mode, and the try to find an operator which is indicated by the application (like in manual mode) . To force an attempt to select and register a network operator, the application must send the following command: Command syntax: AT+COPS=<mode>, [<format> [ , <oper> ] ] Response syntax: OK or +CME ERROR: <err> The parameters values are the following ones: <mode>: 0: automatic (default value) 1: manual 3: set only <format> 4: manual / automatic (<oper> shall be present), if automatic selection fails, automatic mode is entered. <format>: format of <oper> field 0: long format alphanumeric <oper> 2: numeric <oper> (default value) <oper>: operator identifier (MCC/MNC in numeric format only for operator selection). , long alphanumeric format can be up to 16 characters long (see appendice 16. 10} for operator names description, field is } "Name") AT+COPS?Ask for current plmn +COPS: 0, 2, 20801 Home PLMN is France telecom Itineris OK AT+COPS=?Ask for PLMN list +COPS: (2, 20801), (0, 20810) Home PLMN is France Telecom OK SFR network has been seen AT+COPS=1, 2, 20810 Ask for registration on SFR network +CME ERROR: 3 Failed AT+COPS=1, 1, 20810 Ask for registration on SFR network +CME ERROR: 4 Wrong parameters AT+COPS=0, 2 Ask for registration on home network OK Succeed AT+COPS=3, 0 Ask for setting alphanumeric format OK Succeed AT+COPS?Ask for current plmn +COPS: 0, 0, "F Itineris" Home PLMN is France telecom Itineris OK AT+COPS=1, 0, "F SFR" Ask for registration on SFR network +CME ERROR: 3 Failed AT+COPS=4, 0, "F SFR" Ask for registration on SFR network in manual/automatic mode OK Command succeed AT+COPS?Ask for current plmn +COPS: 0, 0, "F Itineris" Home PLMN is France telecom Itineris !OK So the attempt to register on SFR Network has failed but the automatic selection on Home PLMN has succeed.

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.
