Further, a main switch 50 which connects the office lines 30 via the office line device 31 and also connects the automatic dial sending device 40 is controlled by the control device 60. The control device 60 includes call detection means 61.class identification means 62. It has a dial information reading means 63 and a connection control means 64, and mainly controls the main switches by making full use of the programs and data stored in the storage device 70. The storage device [70 has an extension class information storage area 71 and an extension class dial information storage area 72, each of which is stored in advance.

Extension 10 is EXA as an extension terminal (hereinafter f&EX)
11 to EXD14 are connected. For example, EXAll is a terminal dedicated to calling the fire department, and EXB12 is a terminal dedicated to calling the police station. The call detection means 61 detects the extension 1 from the line circuit 20.
0 status notification is received and the calling extension 10 is detected.

The class identification means 62 includes information about the detected calling extension 10;
For example, when EXAll receives information about a call, it reads and outputs class information called a fire department call only class from the EXAII area of the extension class information storage area 71.

The dial information reading means 63 inputs the class information output by the class identification means 62 and searches the extension class dial information storage area 72. For example, the special number "'119" is entered in the class exclusively for calling to the fire station, and the special number "'119" is entered in the class exclusively for calling to the police station. Then, the special number "'110" and one pre-stored telephone number for the specific emergency contact calling class are read and output. The connection control means 64 selects and captures one of the vacant spaces of the central office line device 31 and the automatic dial sending device 40 from the dial code inputted from the dial information reading means 63, controls the main switch 50, and interconnects the inputted code. The dial code is transferred to the automatic dial sending device 40. The automatic dial sending device 40 activates the opening exchange (not shown) when connected to the opening exchange (not shown) via the main switch 50, the central office line device 31, and the central office line 30, and after a predetermined period of time has elapsed, the automatic dialing sending device 40 starts up the opening exchange (not shown) and sends the received dial code after a predetermined period of time has elapsed. is sent to the central office line 30.

Next, the main operating procedures of the control device will be explained with reference to FIG. 2 and FIG. 1. First, when the call detection means 61 detects a call from an extension terminal, e.g.
Output AII.

The class identification means 62 that has received the call information of EXAII identifies the extension class (operation procedure 2) by reading the class information dedicated to fire department calls as an extension class from the extension EXAll area of the extension class information storage area 71. The extension class is for fire department calls only, police station calls only,
In the case of an emergency call class such as exclusive for calling a specific emergency contact (operation procedure 3), the dial information reading means 63 searches the extension class-specific dial information storage area 72 of the storage device 70 based on the extension class received from the class identification means 62. Then, the dial information is read from the corresponding area (operation procedure 4) and transferred to the connection control means 64. In accordance with the received dial information, the connection control means 64 selects and acquires one of the available spaces in the station line bag N31 and the automatic dial sending device 40, and connects them to each other by controlling the main switch 50 (operation procedure 5). The control device 60 connects the automatic dial sending device 40 to the central office line device 31 via the main switch 50.
is connected to the exchange in which is accommodated, and the dial code of the dialing information is transferred to the automatic dial sending device 40, and the exchange is activated via the central office line 30 (operation procedure 6). Waiting for the elapse of time for the exchange to complete dial reception preparations, the automatic dialing sending device 40 starts automatically transmitting the dialing code (operation step 7). By transmitting the dialing code, the destination connected by dialing is called, and the dialed destination responds. Then, the connection control means 64 detects this response via the automatic dial sending device 4o (actuator III 8 ), controls the main switch 50, and disconnects the automatic dial sending device 40 from the central office line device 31. Calling extension 10, e.g. EX
Connect AII, for example EXA], dial from 1 to “1”
