Abstract

PURPOSE:To send a message of a teleguide device to a trunk line at every unit of an incoming dial-in number by converting the dial-in number stored in a main storage device into the teleguide device number when a specific dial-in number is received. CONSTITUTION:When a dial-in number is converted into a number of a teleguide device 4, a specific number from a telephone number added with the dial-in number is sent to a central processing unit 2. Upon the receipt of a specific number, the central processing unit 2 converts the dial-in number into a number assigned to a dial-in number conversion memory of a main storage device 3. The central processing unit 2 decides the number by using a number deciding circuit to be connected to the teleguide device 4 at every unit number and drives the teleguide device 4 to send a recorded message to the trunk line.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a teleguide system in which contents recorded in a teleguide device are transmitted to the central office line in units of PBX dial-in numbers.

[Conventional technology]

Conventionally, when connecting a teleguide device in a PBX, a third
As shown in the figure, the switching is performed either by installing a mechanical switch SW on the central office line side or through the PBX. This is possible because each office line has a fixed number.

[Problem to be solved by the invention]

However, in the PBX dial-in system, there is no fixed number for one office line, so it is not possible to connect to the teleguide device by providing a switch on the office line before entering the PBX. Furthermore, when using a PBX, connection can only be made to a specific line or all lines.

[Means to solve the problem]

The PBX dial-in number-linked teleguide system of the present invention stores the PBX in the main memory of a storage program-controlled private branch exchange.
The X dial-in number and teleguide device number are memorized, and when a specific dial-in number arrives, the dial-in number stored in the main storage device is converted to the teleguide device number and sent to the teleguide device. It is configured to connect and send the contents recorded in the teleguide device in advance to the central office line side.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a diagram showing the main operating procedure of a central processing unit showing one embodiment of the present invention, and FIG. 2 is a diagram showing an example of the configuration of a private branch exchange for realizing FIG. 1.

Referring to both figures, the private branch exchange has a switch 1, a central processing unit 2, a main memory 3, a teleguide device 4, and an extension circuit 5.
It is composed of. When an incoming signal is received, it enters the central processing unit 2 via switch 1 of the exchange. The central processing unit 2 converts the incoming dial-in number by making full use of the programs and data stored in the main storage device 3, and the main storage device 3 drives the central processing unit 2 to convert the incoming dial-in number using the various functions of the exchange. Connect to the extension switch. When converting a dial-in number into a number for the teleguide device 4, a specific number is sent to the central processing unit 2 from the telephone to which the dial-in number is attached. When the central processing unit 2 receives the specific number, it converts it into a number assigned to the dial-in number conversion memory of the main storage device 3. An incoming dial-in number is converted by the central processing unit 2 into a number stored in the conversion memory of the main storage device 3 based on the procedure shown in FIG. 1, and sent to the central processing unit 2. The central processing unit 2 determines the number by a number determination circuit, connects each number unit to the teleguide device 4, drives the teleguide device 4, and sends out the recorded message to the central office line.

〔Effect of the invention〕

As explained above, according to the present invention, by performing number conversion on a dial-in number basis, each dial-in number is converted to a teleguide device number at an arbitrary time from the extension terminal of the dial-in number, and a call is received. Messages from the teleguide device can be sent to the central office line for each dial-in number.

Claims (1)

[Claims] PBX is used as the main memory of storage program controlled private branch exchange.
A dial-in number and a teleguide device number are stored, and when a specific dial-in number is received, the dial-in number stored in the main storage device is converted to a teleguide device number and connected to the teleguide device. This is a PBX dial-in number-linked teleguide system that is characterized by transmitting the contents recorded in advance in the teleguide device to the central office line.
