XT55 AT Command Set - Wireless Data Modules

XT55 AT Command Set8.8 AT^MONIs• To some extent, the cell monitoring command AT^SMONC covers the same parameters. The receiving level,for example, can be queried with both commands. Yet the resulting values may be slightly different, eventhough obtained over a time period of a few seconds. This is quite normal and nothing to worry about, as thecell information is permanently updated.• For compatibility with earlier products and to support legacy applications, any input character may be used tostop the output in certain cases (depending on the settings of AT+IPR and AT+CMUX).8.8.1 AT^MONI responsesME is not connected:a) ME is camping on a cell and registered to the network:Serving CellI Dedicated channelchann rs dBm MCC MNC LAC cell NCC BCC PWR RXLev C1 I chann TS timAdv PWR dBm Q ChMod1013 21 -71 001 01 1001 0103 7 7 33 -105 33 I No connectionb) ME is camping on a cell but not registered to the network (only emergency call allowed):Serving CellI Dedicated channelchann rs dBm MCC MNC LAC cell NCC BCC PWR RXLev C1 I chann TS timAdv PWR dBm Q ChMod1013 21 -71 001 01 1001 0103 7 7 33 -105 33 I Limited Servicec) ME camping on a cell, but searching for a better cell (cell reselection):Serving CellI Dedicated channelchann rs dBm MCC MNC LAC cell NCC BCC PWR RXLev C1 I chann TS timAdv PWR dBm Q ChMod1013 21 -71 001 01 1001 0103 7 7 33 -105 33 I Cell Reselectiond) ME is searching and could not (yet) find a suitable cell:Serving CellI Dedicated channelchann rs dBm MCC MNC LAC cell NCC BCC PWR RXLev C1 I chann TS timAdv PWR dBm Q ChModSearchingME is connected (Call in progress):Serving CellI Dedicated channelchann rs dBm MCC MNC LAC cell NCC BCC PWR RXLev C1 I chann TS timAdv PWR dBm Q ChMod1013 19 -76 001 01 1001 0103 7 7 33 -105 33 I 1015 1 0 5 -76 0 S_HRColumns for Serving Cell:ColumnchannrsdBmMCCMNCLACcellNCCBCCPWRDescriptionARFCN (Absolute Frequency Channel Number) of the BCCH carrierRSSI value 0 - 63 (RSSI = Received signal strength indication)Receiving level of the BCCH carrier in dBmMobile Country Code (first part of the PLMN code)Mobile Network Code (second part of the PLMN code)Location area code, see note belowCell IDPLMN colour codeBase station colour codeMaximal power level used on RACH channel in dBmXT55_ATC_V03.03 Page 177 of 459 9/9/05Confidential / Released
