Conventionally, when any subscriber dials to make a call to subscribers ST ₁ to ST ₄₄ , the port number of the subscriber to ring signal service is stored in RAM 13 as a database as shown in FIG. 2a. The central control unit 10 alternately performs ring service ON and OFF at two second intervals through the ring relay driver to port numbers for ring signal service stored in one table and two tables according to a program order. That is, when performing cycle 1, save the port number after executing the ring signal service program that turns on the ring signal service to the port number stored in 1 table and turns off the ring signal service to the port number stored in 2 table. The program is run. After 2 seconds have elapsed, perform cycle 2 to turn off the ring signal service for the port number stored in 1 table, turn on the ring signal service for the port number stored in 2 table, and then repeat the cycle after 2 seconds have elapsed. Do this.

The exchange has a program to store the port address to service the ring signal when there is a request from the subscriber, and a program sequence to perform the ring signal service. In FIG. 2C, period 1 finishes the ring signal service at the point A in FIG. When the port address is stored in one table by the port number, the port number stored in the one table has two seconds of turning on and off the ring signal service. Therefore, the ring signal is turned on at the point B of FIG. In the worst case, the subscriber has to wait 4 seconds for the ring signal service to be turned on after the ring signal service port is stored.In addition, when the subscriber who receives the ring signal service picks up the handset to make a call, The control unit shall suspend the ring signal service by the program sequence of the exchange. If you need to stop ring signal service, it is not possible to know where port number to stop ring signal service is stored in the table. Therefore, you need to find port address sequentially until each ring signal stop port is found in each table. There is a problem that stops cannot be performed quickly.

Accordingly, an object of the present invention is to increase the number of table numbers storing the port number for ring signal service, so that the ring signal service is turned on and off by 1 second, thereby ringing the port number stored in any table. If the port address for ring signal service is stored in any table after performing signal service on, the ring signal service is turned on at least 3 seconds later. Another purpose is to ring the ring signal service stop table. The present invention provides a ring signal service control method for quickly finding a ring signal service stop port number when a ring signal service stop is performed by recording an address in which a port number for stopping signal service is stored.

In order to achieve the above object, the present invention provides a ring signal service control method of a subscriber exchange for exchanging multiple subscribers, wherein the called subscriber port number for serving a ring signal is circulated through a plurality of ring service tables to a corresponding ring service table. Registering and registering the address of the registered ring service table at a address corresponding to the called subscriber port number of the ring service stop table; While the ring signal is supplied to the called subscriber port registered in one ring service table at a predetermined period, another ring service is started simultaneously with the supply of the ring signal to the called subscriber port registered in the other ring service table. A called subscriber port registered in the table, a service process of serving a ring signal while circulating a plurality of ring service tables in a manner of interrupting supply of ring signals; If the request for stopping the ring service is checked from the registered called party while performing the above steps, the address of the ring service table registered at the corresponding address of the ring service stop table is read and the corresponding ring service table stops the ring service. It characterized in that it comprises a process of reading the address of the ring service table registered at the corresponding address and deleting the called subscriber port number registered at the corresponding address in the ring service table during the ring service.
