PURPOSE: A charging processor for a private exchanger is provided to prevent a charging data from losing due to an abnormal state of a charging equipment by determining a transmission state of the data by checking existence or nonexistence of a fault in the charging equipment in a manner that a response signal transmitted from a pertinent charging equipment is checked whenever charging data are transmitted by block unit. CONSTITUTION: A charging data generator(111) generates charging data corresponding to a generated call when a signal informing of a call generation is applied from a call processor(100). The first charging data storing unit(112) stores the charging data transmitted by 1 call unit from the charging data generator(111) and outputs it by a block unit. A timer(113) measure time corresponding to the time during which the charging data corresponding to one block is generated in synchronization with the charging data of the 1 call outputted from the charging data generator(111). A counter(114) counts the charging data outputted from the charging data generator(111) by 1 call unit. An output controller(115) logically combines the output signals of the timer(113) with the charging data counter(114), and controls the output state of the first charging data storing unit(112). The second charging data storing unit(116) stores the block unit of charging data outputted from the first charging data storing unit(112) by sector unit. The third charging data storing unit(117) stores the charging data transmitted as an automatic dump phenomenon occurs for the data stored in the second charging data storing unit(116) due to an error of a CDR, in a file format. An RS-232C data transmitting and receiving unit(119) transmits the charging data transmitted from the second charging data storing unit(116) or the third charging data storing unit(117) to the CDR in an RS-232C data format, and receives the RS-232C format data from the CDR. An abnormal state detector(118) detects an abnormal state of the CDR in a manner of checking whether an acknowledgement signal is transmitted from the CDR through the RS-232C data transmitting and receiving unit(119), and controls the operation of the second charging data storing unit(116).
