Output ports a corresponding to 13, the b and c 1 primary dial number (e.g., 7-digit number) is assigned respectively
And the primary dial numbers are the terminals 1a, 1b,.
n users.

Next, the operation of this embodiment will be described.

For example, a primary dial number (for example, a primary dial number assigned from the terminal 1a to the output port a of the exchange switch 30)
When dialing the above-mentioned seven-digit number), the terminal 1a receives a call to the SPC 3A through the telephone network 2, and is connected to the service designation code setting unit 311 through the exchange switch 30. In the storage device 31, the communication control unit 32 reads the service designation code (corresponding to the above-mentioned secondary dial number) indicating the "broadcast service" set in the service designation code setting unit 311 and adds the service designation code from the terminal 1a. Wait for transmission of the service designation number.

If the communication control unit 32 does not receive an additional service designation number within a predetermined time, it sends only the service designation code set in the service designation code setting unit 311 to the service analysis unit 33, and the service analysis unit 33 Analyzes the service designation code, determines that the broadcast is "broadcast", and instructs a central processing unit (not shown) to control the operation of "broadcast" transmission. The central processing unit controls the operation of generally known "broadcast".

Further, within a predetermined time after the communication control unit 32 reads the service designation code of "broadcast service" from the service designation code setting unit 311, it receives an additional service designation number (indicating a broadcast notification destination). In this case, the service designation code indicating the "broadcast service" and the additional service designation number are sent to the service analysis unit 33, and the service analysis unit 33 determines that the broadcast is "general broadcast" and sends the analysis result to the central processing unit. Notify. The central processing unit controls the operation of general broadcast transmission to the designated broadcast notification destination.

Next, for example, when the terminal 1b dials the primary dial number assigned to the output port b of the exchange switch 30, the terminal 1b
3A, and is connected to the service designation code setting unit 312 through the exchange switch 30. In the storage device 31, the communication control unit 32 reads out the service designation code indicating the “electronic bulletin board retrieval service with no designated bulletin board number” set in the service designation code setting unit 312, and adds the additional service from the terminal 1b. Wait for the specified number to be sent. The communication control unit 32 receives the additional service designation number indicating the bulletin board number from the terminal 1b, and sends the service designation code and the designated electronic bulletin board number to the service analysis unit 33.

The service analysis unit 33 transmits the result of analyzing the received code and number to the central processing unit, and the central processing unit controls the operation of the generally known operation of “pulling out posting data from the electronic bulletin board of the designated number”. Do.

Next, for example, when the terminal 1n dials the primary dial number given to the output port c of the exchange switch 30, the terminal 1n is connected to the SPC through the telephone network 2.
3A, and is connected to the service designation code setting unit 313 through the exchange switch 30. In the storage device 31, the communication control unit 32 reads out the service designation code indicating the “electronic bulletin board registration service” set in the service designation code setting unit 313 and sends it to the service analysis unit 33.

The service analyzing unit 33 transmits the result of analyzing the received service designating code to the central processing unit. The central processing unit controls the operation of “registering an electronic bulletin board” which is generally known, and executes the operation of the registered electronic bulletin board. Number to telephone network 2
To the terminal 1n.

As described above, in this embodiment, when receiving a service that does not require an additional service designation number, such as "broadcast service" or "electronic bulletin board registration", only the primary dial number needs to be dialed. In the case of "general broadcast service" or "electronic bulletin board withdrawal service", a minimum secondary dial number may be additionally dialed after the primary dial number.

Note that the present invention provides the broadcast service described above,
The present invention can be applied not only to general broadcast services and electronic bulletin board registration / withdrawal services, but also to other services.
