Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clock control method for controlling billing in an automatic exchange.

Conventionally, automatic switching equipment generates billing data containing various information necessary for billing control every time the subscriber or line status changes (when dialing is completed, when the other party responds, etc.), and the billing data is sent to the billing processing device. Sending out. That is, this billing data includes caller number information, called party number information, and status information (that is, information indicating a call, a response from the other party, a call termination, etc.). When the billing device receives this billing data, it immediately performs processing based on the reception time and the content of the billing data described above. When billing data is processed by a data processing device provided outside an automatic exchange, clock information is not included in the billing data sent from the automatic exchange to the data processing device. Therefore, the data processing device requires real-time processing of reading clock information from its own clock circuit every time billing data is sent, and has the drawback of requiring fast processing speed and high processing capacity.

The purpose of the present invention is to eliminate the above-mentioned drawbacks by adding clock information to billing data in an automatic exchange and then transmitting it to an external data processing device, so that the external data processing device does not require a clock circuit and can operate at a low processing speed. This invention provides a clock control method for an automatic exchange that is capable of processing billing data.

The clock control method for an automatic exchange according to the present invention includes: an interface circuit of an automatic exchange having an interface circuit for transferring billing data via a communication line to an external data processing device that processes billing data; an input buffer register that receives billing data from a billing data collection processor of the input buffer register, a memory that stores the billing data received by the input buffer register, a clock circuit that generates time information, and a clock circuit that transmits time information to the communication line. An output buffer register into which data is written, and an interface processor that reads out the billing data stored in the memory, adds the time information, and sends the data to the communication line via the output buffer register. It is characterized by:

Next, an embodiment of the present invention will be described with reference to FIG.

In FIG. 1, billing data generated within an automatic exchange 1 is once sent to a billing data collection processor 2. The billing data collection processor 2 formats the received billing data into a certain data format, divides it into units of a certain amount of data, and sends the divided data to the interface circuit 3. In the interface circuit 3, the interface processor 6 reads out the sent billing data from the input buffer register 4 and temporarily stores it in the temporary storage memory 5. Note that the billing data sent from the billing data collection processor 2 is not necessarily sent for each round of data. The interface processor 6 identifies the boundaries of each piece of data that is sent intermittently, and the clock information is read out from the clock circuit 7 only when a series of data is complete. The time in the clock circuit 7 includes the year, month, day of the week, day, hour, minute, second, etc., and each information is displayed on the display circuit 8. Furthermore, the clock correction circuit 9 allows the time to be set and corrected manually using a switch. The interface processor 6 is a clock circuit 7.
The clock information read from the computer is added to the billing data stored in the temporary storage memory 5 according to a certain format, and the data is written into the output buffer register 10. The billing data with the clock information written in the output buffer register 10 in this manner is transferred at a constant speed to an external data processing device through the communication line 11. Therefore, since the external data processing device already receives billing data that includes clock information, it is not necessary to have a clock circuit. Further, there is no need to perform real-time processing to register the reception time of billing data.

As explained above, the present invention employs a method in which clock information is added to billing data in the interface circuit of an automatic exchange and then transferred to an external data processing device, thereby allowing clock information to be registered in the external data processing device. This eliminates the need for real-time processing for
Therefore, it is possible to use a low processing capacity, which has the effect of allowing the use of inexpensive data processing equipment.
