5.4.3î™–î™–î™–î™–Defined values
Parameter Type Description
<conf> Number The unsigned integer (0 to 4095) is a bitmask representing the list of the indications
active for +CIEV URC reporting. The bit position corresponds to the indicator order
number (see the <descr> parameter of +CMER). The least significant bit is used for
the first indicator.
The bits corresponding to unused indicator order numbers (greater than 13) must be
set to 0 (setting a <conf> greater than 4095 causes an error). The default value is 40
95 (all the indications are enabled).

The URC is generated each time an indicator which is defined in +CIND command changes status. The code is
actually submitted to MT according to the +CMER settings.
The command +UCIND allows enabling or disabling indicators.
