JPS63272257A - Communication system between data equipment and telephone set using pb signal - Google Patents

Abstract

PURPOSE:To attain data communication between a general telephone set and a data equipment by adding a converting function between a PB signal and a data signal to a telephone set. CONSTITUTION:A telephone set 1a is a conventional PB telephone set and a telephone set 1b is a telephone set having a conversion function between PB communication and a data signal. When a user at the telephone set 1a desires to input a data to the data equipment 2, the user dials a number to the telephone set 1b through a telephone exchange network 3. The telephone set 1b applies automatic reply depending on its automatic reply function and a speech path is set. Then the user applies ten-key operation of the telephone set 1a to send the data desired to be inputted to the telephone set 1b as a PB signal. The telephone set 1b converts the received PB signal into a data signal and sends the data signal to the data equipment 2.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to data communication systems using general telephones, especially PB
Data having a general telephone that can make a call and a data communication interface such as R3232C is related to a data communication system between devices.

[Prior Art] Conventionally, this type of data communication system requires a special device called a voice response device, and is realized by mutually converting the voice signal and the PB double signal data signal from the telephone in that device. Ta.

[Problem to be Solved by the Invention 1] In the conventional data communication system described above, the main purpose of the voice response device is rarely automatic voice response, so the device is generally complicated and expensive. Therefore, in a system that performs simple data communication with a data device using the numeric keypad of a telephone, it has the disadvantage that it is difficult to apply.

An object of the present invention is to provide a communication system most suitable for data communication between a general telephone and a data device.

[Means for Solving the Problems 1] The present invention is a system for performing data communication with a data device using the PB double signal of a general telephone, in which the data device is equipped with a telephone, and the telephone receives incoming calls from the telephone exchange network. An automatic response circuit that automatically responds to a signal, and a P that is input from a general telephone to the communication path set by the automatic response of the automatic response circuit.
This is a communication system between a telephone and a data device using a PB double signal, which is characterized by adding a conversion circuit that mutually converts the B signal and the data signal of the data device.

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

FIG. 1 is a system configuration diagram of an embodiment of the present invention. The telephone 1a is a normal PB telephone, the telephone 1b is a telephone having a conversion function between PB communication and data I8, and the telephones 1a and lb are capable of making calls via the telephone switching network 3.

The data device 2 is connected to the telephone 1b through a line interface such as an R3232C interface. The data communication system of the present invention is realized by a telephone set 1b having a function of mutually converting PB double signal data signals.

The telephone Fj11b has a telephone call circuit 9, a tone ringer circuit 4. In addition to the PB dial oscillation circuit 5, there is also a PB double signal data signal conversion circuit 1.
0. Automatic response circuit 6. It has a data equipment interface circuit 11.

Handset (telephone, handset>7.8. Call circuit 9, tone ringer circuit 4. PB dial oscillation circuit 5 is a basic function of a normal telephone, and is a functional block 5.10.1
1 is a function unique to the present invention.

The conversion circuit 10 converts P input from the general telephone 1 into the communication path.
The interface circuit 11 has a function of mutually converting the B-time signal and the data signal of the data device 2, and provides an interface for data communication with the external data device 3. The automatic response circuit 6 provides a function for automatically responding when a call is received from the telephone exchange network.

Next, in this system example, the operation of the system when the user on the telephone 1a side wants to input data into the data device 2 will be described. The user first dials into the telephone exchange network 3 to place a call to the telephone set 1b. Telephone 1b automatically responds using its automatic response function, and a communication path is established between telephones 111a and 111b. After that, the user operates the numeric keypad on the telephone 1a to
The data to be input is multiplied by PB and sent to the telephone set 1b. The telephone set 1b converts the received PB multiplied data signal into a data signal, and sends the data signal to the data device 2. Through the above operations, data input from the telephone GLLA to the data device 2 is completed.

[Effects of the Invention] As explained above, the present invention has the necessary effect of easily realizing data communication between ordinary telephones and data devices by adding a PB double signal data signal conversion function to the telephone. Ru.
