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).

5.5.1Description
Configures sending of URCs from MT to DTE for indications. The <mode> parameter controls the processing
of URCs specified within this command.
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.

Parameter Type Description
<mode> Number
• 0 (default value): buffer URCs in the MT
• 1: discard URCs when the V.24 interface is reserved for data; otherwise directly
display them on the DTE
• 2: buffer URCs in MT when the V.24 interface is reserved and flush them after
reservation; otherwise directly display them on the DTE
• 3: same as 1
<keyp> Number
• 0: no keypad event reporting
<disp> Number
• 0: no display event reporting
<ind> Number
• 0: no indicator event reporting
• 1: indicator event reporting using the +CIEV URC. Only the indicator events which
are not caused by +CIND shall be indicated by the MT to the DTE.
• 2: indicator event reporting using the +CIEV URC. All the indicator events shall be
directed from MT to DTE.
