decimal format

LAC location area code, in hexadecimal format. See note below.
cell 4-digit Cell ID in hexadecimal format. 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 cell selection criterion
Dedicated channel:
chann ARFCN (Absolute Frequency Channel Number) of the TCH carrier
Note: <chann> = h indicates frequency hopping.
TS timeslot number
timAdv timing advance in bits
PWR current power level
dBm receiving level of the traffic channel carrier in dBm
Q receiving quality (0–7)
ChMod channel mode (S_HR: Half rate, S_FR: Full rate, S_EFR: Enhanced Full

Depending on the service state, an additional textual output is generated (refer
also to the response examples):
‘Searching’ - The MS is searching, but could not (yet) find a suitable cell. This out-
put appears after restart of the MS or after loss of coverage.
‘No connection’ - The MS is camping on a cell and registered to the network. The
service state is ‘idle’, i.e. there is no connection established or a dedicated channel
in use.
‘Cell Reselection’ - The MS has not yet lost coverage but is searching for a better
cell, since the cell reselection criterion is fulfilled.
‘Limited Service’ - The MS is camping on a cell but not registered to the network.
Only emergency calls are allowed. The MS enters this state, for example, when
- no SIM card is inserted, or PIN has not been given,
- neither Home PLMN nor any other allowed PLMN are found,
- registration request was not answered or denied by the network (use com-
mand AT+CREG to query the registration status),
- authentication failed.
