<chann>
ARFCN (Absolute Frequency Channel Number)

<RSSI>
Received signal level of the BCCH carrier (0..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
<C1>
Coefficient for base station reselection; e.g., 30. In dedicated mode, under certain conditions the parameter
cannot be updated. In such cases a '-' is presented.
<C2>
Coefficient for base station reselection; e.g., 30. In dedicated mode, under certain conditions the parameter
cannot be updated. In such cases a '-' is presented.
To some extent, the cell monitoring commands AT^MONI, AT^MONP and AT^SMONC cover the same

parameters. The receiving level, for example, can be queried with all three commands. Yet the resulting
values may be slightly different, even though obtained over a time period of a few seconds. This is quite
normal and nothing to worry about, as the cell information is permanently updated.
Multi-Tech Systems, Inc. AT Commands for EDGE Modems (S000371G)
The AT^SMONC execute command delivers cell information containing 9 values from a
maximum of 7 base stations.
The first base station is the serving cell.

Cell ID currently not available because the cell ID information is not yet
read from the Sysinfo 3 transmitted by the base station.
Not decoded
Not decoded. In this case, all remaining parameters related to the same
channel are neither decoded. For example, a non-existing cell appears
