Abstract

PURPOSE:To execute the simultaneous calling process of both data and sound by connecting a signal converter between a telephone set and a data terminal and connecting two dial signal receiving means between an exchange and the telephone set. CONSTITUTION:When sound is originated from the telephone set 4 stored in a digital exchange 7 and connected to a line circuit 4 having a data communication function, the dial signal is repeated by a signal receiving means 5 for receiving the sound in the line circuit 4 and sent to the exchange 7. When data are simultaneously originated from a data terminal 1 having a keyboard, dial number characters are converted into a dial signal by the signal converter 2 and sent to the line circuit 4 through the telephone set 3. Thus, dial signal is repeated by a signal receiving means 6 for the data and sent to the exchange 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connection control system in a digital exchange system capable of simultaneous voice and data communication.

[Conventional technology]

Conventionally, as shown in FIG. 5, in a digital exchange 7 capable of simultaneous voice and data communication, there is a line circuit 4 having voice and data communication functions, and a line circuit 4 connected to this line circuit 4, It has a telephone 3 that performs dialing control and a data terminal 1 having a keyboard connected to the telephone 3, and all connection control for voice and data when making a call is performed from the telephone 3.

[Problem that the invention seeks to solve]

In the above-mentioned conventional connection system, a line circuit 4 having eight functions for voice and data communication is provided with dial signal receiving means 11 from a telephone that performs dial control for voice communication and voice, and dial control for data communication and data. Because they are shared, data calls cannot be made while voice calls are being made, and conversely, voice calls cannot be made while data calls are being made.

An object of the present invention is to provide a connection control system that enables simultaneous data and voice call processing.

[Means for solving problems]

The present invention relates to a digital switching system capable of simultaneously communicating data from a data terminal and voice from a telephone, including a line circuit housed in the exchange for voice and data communication, and a line circuit connected to the line circuit for voice and data communication. a telephone that performs dialing control and data communication for and dialing control for data; a data terminal; and a conversion device that is connected between the data terminal and the telephone and converts dialed number characters into dialed signals; This is a connection control system characterized in that a line circuit is separately provided with a receiving means for receiving a dial signal from the telephone set and a receiving means for receiving a dial signal from the switching device.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, the connection control method of the present invention is shown as a line circuit 4 which is housed in a digital exchange and has voice and data communication functions.
and is connected to this line circuit 4.

A conversion bag fi2 is connected between a telephone 3 that performs voice communication, voice dial control, data communication, and data dial control, and a data terminal 1 having a keyboard, and converts dial number characters from the keyboard into a dial signal. By adding , it is possible to make a call from the keyboard, and by separately providing dial signal receiving means 5 for voice and dial signal receiving means 6 for data on the line circuit 4. This enables simultaneous call processing for data and voice.

In the embodiment, first, when a voice call is made from the telephone 3 that performs voice communication and voice dial control, voice control signal information is placed in the voice control signal part of the signal format shown in FIG. 2, and the line circuit 4, the dial signal is relayed by voice signal means 5 in line circuit 4 and sent to exchange 7.

At the same time, when the data terminal 1 having a keyboard inputs a data number character and makes a data call, the control signal information for the data is placed in the data control signal part of the signal format shown in FIG. 2 and sent to the line circuit 4. The dial signal is relayed by the signal receiving means 6 for data in the line circuit and sent to the exchange 7. This makes it possible to independently connect the telephone 3 and the keyboard data terminal 1.

Furthermore, since calls can be made directly from the data terminal 1 with a keyboard, there is no need to place a telephone nearby and dial when making a data call.

FIG. 3 shows another embodiment of the present invention, and shows a voice and data connection control method using dial numbers programmed in a data terminal. In FIG. 3, 8 is a keyboard, and 9 is a program storage medium. The program is loaded into the memory within the data terminal 1 and executed. 10 is a database. Further, 11 is a telephone, and 12 is a public network.

The procedure for connecting the keyboard 6 to the database 10 is carried out in the same manner as described with reference to FIG. The database 10 contains customer names, their contact telephone numbers, and information necessary for business, and by providing the key information necessary for selection from the data terminal 1, a list of candidate customers is displayed on the data terminal technician's screen. 1 of the candidate line on the 0 screen
Select a person.

By pressing the execution key, a voice dial is performed from the data terminal 1, and the connection is completed when the other party responds. Thereafter, the user will interact with the customer while checking the customer's information using the data terminal 1. FIG. 4 shows a sequence chart at this time.

〔Effect of the invention〕

As described above, the present invention enables voice and data dialing to be performed independently by providing two dial signal receiving means. Furthermore, it is effective to use a program in the data terminal to dial voice calls to frequently used parties or to parties included in the database, which has the effect of eliminating erroneous dialing.
