6.2 AT^MONI Monitor idle mode and dedicated mode
Test command
AT^MONI=?
Response
^MONI: (list of supported < period >s) OK
Write command
AT^MONI[=<pe
riod>]
This command can be used to retrieve, automatically every n seconds, information
on the serving/dedicated cell. The display can be terminated by any character sent
to serial port except if autobauding is enabled (+IPR=0). Then type character ´a´ to
abort.
Note:
The two header lines (see below) are output after every ten data lines.
Response
See execute command
Parameter
<period> 1 – 254 Display period in seconds
Execute command
AT^MONI
This command can be used to retrieve, on request, the cell parameters of the
serving/dedicated cell.
Note:
The length of following output lines exceeds 80 characters. Therefore a terminal
program may draw a carriage return on a screen. However, this is not part of the
response.

Parameters
Serving Cell:
chann ARFCN (Absolute Frequency Channel Number) of the BCCH carrier
rs RSSI (Received signal strength) of the BCCH carrier from 0 to 63. The
indicated value is composed of the measured value in dBm plus an
offset. This is in accordance with a formula specified in 3GPP TS 05.08.
dBm receiving level of the BCCH carrier in dBm
PLMN PLMN ID code
LAC location area code, see note below.
cell cell ID, see note below.
NCC PLMN colour code
BCC base station colour code
PWR maximal power level used on RACH channel in dBm.
RXLev minimal receiving level (in dBm) to allow registration
C1 coefficient for base station selection
