The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, with reference to the accompanying drawings, it will be described in detail a preferred embodiment of the present invention.

First, referring to FIG. 1, the input / output device 100 is a device for controlling input and output of a system, and loads a program of a main processor (in a system operation / maintenance block), backs up changed data, an operator and a system. It provides communication channel and cartridge tape driver and floppy disk driver, and can operate remote visual audible alarm device.

And, the call processing timer management table block 102 is a block for storing and operating the tone according to the call processing timer with the establishment / centrix / private information in advance according to the generation of the call of the subscriber.

The subscriber / relay line control block 104 is a block that detects whether a subscriber is a national / centric / private subscriber when the subscriber picks up the handset and the subscriber loops the line.

The digit reception processing block 106 performs digital signal processing on the MFC signal to periodically scan each channel of the signal reception equipment that detects digit information to detect digits. In the case of a dial pulse, the subscriber line is periodically scanned to count the number of breaks of the dial pulse to detect a digit.

Examples of the customer group include a local subscriber, a centric subscriber, a private subscriber, and a mobile subscriber, and the time of each timer driving is different.

The call processing timer is present in the call processing timer management block, and the call processing timer driver operates according to the control of the system operation maintenance block, and a maximum value, a default value, and a minimum value are determined for each tone, so that each tone is set by the operator. It is possible.

The digit receiving processing block 106 analyzes the received digits to obtain information such as the type of call and the expected total number of digits, and further analyzes the remaining digits to obtain the called subscriber.

The system operation maintenance block 108 is a block that is in charge of the maintenance, maintenance, network management, billing, statistics, test, and database management of the system.

The call processing block 110 performs various functions related to call processing and includes various blocks.

First, the call processing timer driver 112 receives signals from the call processing timer management table block 102, the subscriber / relay line control block 104 and the digit reception processing block 106, and the system operation / maintenance block 108 ) Is a block that rings the ring by driving a timer according to the related national / centrix / private caller.

The subscriber call control unit 114 connects the incoming subscriber terminal and the incoming call line based on the digit information on the incoming signal and sends an intermittent call signal to the incoming telephone to send a ring tone to the called subscriber. Receiving a signal from the relay line call, and the outgoing route occupancy section 118 that detects and occupies and assigns an empty relay line to the subscriber.

The relay line call control unit 120 receives a signal from the outgoing call occupancy unit 118 and controls a signal going out to the power station through the relay line.

Referring to FIG. 2, an input for requesting to register / delete / change the call processing timer value is input through the input / output device 100 or the operator of the customer group (step 210).
