8.8 AT^MONI Monitor idle mode and dedicated mode
The AT^MONI command supplies information of the serving/dedicated cell. There are two ways to retrieve the
information: once on request by using the execute command or automatically every <period> seconds by using
the write command. To stop the periodic presentation type "AT" or "at".

Notes
• The two header lines (see Section 8.8.1, AT^MONI responses) are output after every ten data lines.
• 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.
• The parameters LAC and cell are presented as hexadecimal digits, the remaining parameters are composed
of decimal digits.
• If the radio cell changes during a connection, the parameters PWR, RXLev and C1 of the 'Serving Cell' part
cannot be updated under certain conditions and therefore, are displayed as "-" (for conditions see also
AT+CREG). This is because the MS does not update the cell selection and reselection parameters since, in
this mode, they are not relevant for operation. When the connection ends, and the mobile is back to IDLE
mode, correct values will be given.
If the radio cell changes during a connection, it normally takes 1 or 2 seconds to update the parameters cell,
NCC and BCC. Until the information is received from the new base station, the default values will be shown
instead: cell="0000", NCC="-", BCC="-".
• If the BS supports frequency hopping during a connection, the dedicated channel (parameter chann) is not
stable. This mode is indicated by chann = 'h'.
