Abstract

PURPOSE:To recognize who is an opposite party, i.e., a caller against a ringing telephone set by storing a voice signal and sounding the voice together with a ringing bell tone to call the operator after a communication line is reconnected to a data communication terminal equipment. CONSTITUTION:When the arrival of a call signal is detected by an incoming call detection section 3, a line changeover section 5 selects a communication line 2 to a data communication section comprising a MODEM or the like and a voice synthesis section 7 sends a voice reply such as 'Please be ready for facsimile transmission'. When a signal from the caller is a voice signal and the voice signal is detected, the voice signal from the picture is sampled for 2sec and stored in a voice memory 13. Then a bell tone and the voice signal stored in the voice memory 13 is alternately sounded.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a line switching device, and particularly to a line switching device that is capable of notifying a receiver of a voice signal from a caller when switching a communication line to a caller. It is.

2. Description of the Related Art In recent years, a single communication line has been commonly used for voice communication using a voice communication function and data communication using a data communication function, such as in facsimiles with telephones.

A conventional example of such a line switching device is disclosed in Japanese Patent Application Laid-Open No. 64-29052, for example.

This line switching device detects a ringing signal on the communication line with a signal detector, activates a signal generator to output a bell signal to the telephone when the ringing signal is a call signal, and switches when the telephone goes off-hook. The means connects the communication line to the telephone set, and when the calling signal is a data communication signal, the switching means switches the communication line to the data terminal device side.

Problems to be Solved by the Invention However, in such a conventional line switching device, after detecting a calling signal from a communication line, if this calling signal is a signal for a telephone call, the following operation is performed. Since the system only outputs a ringing bell signal to call the operator on the receiving side, it is difficult for the operator on the receiving side to know who is on the other end of the ringing phone, that is, who is the caller. There was a problem that I couldn't do it.

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a line switching device having a function of notifying who the caller is when switching the communication line to the telephone side. be.

Means for Solving the Problems In order to achieve the above object, the present invention provides a line switching device with:
a ringing signal detecting means for identifying a ringing signal on a communication line; a means for switching the communication line between a telephone and a data terminal unit; A calling bell section that calls by ringing, means for outputting a message for confirming the other party to a caller when the calling signal is a voice call signal, a memory member for storing a voice signal answered by the caller, and a memory. While transmitting the audio signal stored in the member to the calling bell part along with the calling bell and making the sound ring,
The present invention further comprises a control section that operates the switching means to switch the communication line to the telephone side when the hook switch is closed.

In the present invention, when a calling signal sent through a communication line is detected and determined to be a voice call signal, before switching the communication line to the telephone side, the caller is informed of who the caller is. A confirmation message will be sent. Then, the voice signal from the caller related to the response is stored in the memory member. Next, when outputting a call bell signal on the receiving side, the voice signal from the caller is read out from the memory member and transferred to the call bell section. The call bell unit outputs the call bell and also rings the audio signal.

Further, reference numeral 8 is a hand center used by the operator for conversation, 9 is a speech circuit that generates and reproduces signals for voice calls, 10 is a numeric keypad used to enter a dial number when making a call, and 11 is a numeric keypad used to enter a dial number. The handset 8, the speech circuit 9, the numeric keypad 101 and the dial circuit 11 constitute a telephone set 12. Furthermore, in this line switching device, the code 13
14 is a memory member that stores the audio signal from the caller when the calling signal is a voice call signal; and 14 is a call level unit 15 that sounds the audio signal stored in the memory member along with the call bell. An answering machine 16 attached to the main body telephone (hereinafter particularly referred to as the main body telephone) is an attached telephone switching unit that switches the communication line 2 between the main body telephone 12 and the answering machine 15 when performing a reception operation.

The system control unit 1 includes a CPU and a program for operating the CPU, and performs various processes and operations necessary for line switching operations based on this program. Furthermore, the speech synthesis section 7 uses an LSI. Furthermore, the attached telephone switching s16 includes a pseudo 16 Hz sending circuit that calls the answering machine 15, and a circuit that switches between the answering machine 15 and the main body telephone 12.

The operation of the line switching device having such a configuration will be explained below. Here, we will take up a facsimile machine as a data terminal unit.

FIG. 2 is a flowchart showing an example of a line switching control procedure in this embodiment. In this line switching device, first, a processing step (hereinafter simply referred to as step) S
In the TI, the system control unit 1 sends a call signal (16
Hz), and when the incoming call detection section 3 detects that there is an incoming call signal, the process moves to step ST2, and the line switching section 5 switches the communication line 2 to a modem or the like. switch to the data communication section. Next, in step ST3, the voice synthesis section 7 sends out a voice response such as "I'm sorry, but if you are using a facsimile, please perform the sending operation." After sending out the voice response, a signal from the calling side is monitored for a certain period of time in step ST4. Then, in step ST5, it is checked whether or not an audio signal has been detected, and if not detected, step ST5 is performed.
At step 6, it is checked whether CNG is detected. Whether or not these audio signals are detected (step 5T5) and CNG
If there is no detection in the check for detection (step 5T6), time is monitored in step ST7. If the signal from the calling side is CNG or a certain period of time has expired with no sound, it is determined that the calling side is performing automatic facsimile transmission or manual facsimile transmission, and step ST8
The CED is sent out at step ST9, and facsimile reception processing is performed based on the facsimile communication procedure at step ST9.

After the facsimile reception is completed, the line switching unit 5 switches the communication line to the telephone set 12 in step 5TIO, and the communication line 2 is disconnected in step 5TII. The procedure of the above facsimile reception operation is shown as a timing chart in FIG.

On the other hand, if the signal from the calling party is a voice signal and this voice signal is detected in step ST5, the process moves to step 5T12, where 2 seconds of the other party's voice is sampled and stored in the voice memo January 3. . Then, step 5T13
After setting the telephone ringing time in the timer built in the system control unit 1, a bell sound and the voice stored in the voice memory 13 are alternately sounded in step 5T14. The ringing pattern at this time may be, for example, as shown in FIG. 4, a ringing pattern for 1 second followed by a sound for 2 seconds, which is repeated in accordance with a normal telephone ringing pattern. In other words, it is bell sound Yamamoto (Bell sound Yamamoto) (1 second) (2 seconds) (1 second) (2 seconds) and so on. The ringing time of the call bell and voice can be changed by setting, and it is checked in step 5T15 whether or not the receiving operator picks up the handset and hooks off within the set time.

Then, it is checked in step 5T16 whether or not the set time has timed out, and if the timeout has occurred without hooking off, the process moves to step 5T17, where the ringing of the ringing bell and voice is interrupted, and in step 5T18, the answering machine 15 is connected. Check whether it was done or not. If the answering machine 5 is connected, the attached telephone switching unit 16 switches the communication line 2 to the answering machine 15 side, and further sends an answering machine call signal (pseudo 16H7) to the answering machine 15. While sending this answering machine call signal, an apologetic voice in step 5T20 says, ``I called you, but I'm sorry to hear that. Please send a voice message saying, ``Please call me.'', and then, in step 5T21, an answering machine is processed, and then in step 5T22, the communication line is disconnected.

Further, when it is determined in step 5T18 that the answering machine 15 is not connected, step 5T23
After transmitting an apologetic voice saying, ``I called you, but Q is not available. Please call again later.'' In step 5T22, the communication line is disconnected.

Furthermore, when hook-off is detected in step 5T15, the process proceeds to step 5T24, where the ringing of the ringing bell and voice is interrupted, and further, in step 5T25, the communication line M2 is switched to the main body side telephone 12 by the operation of the line switching unit 5. Switch to call mode.

As described in detail, according to the present invention, when an incoming call is detected, the communication line is switched to the data communication terminal side, and then a signal input via the communication line is detected. If the signal is a voice signal, it is stored in memory and rings along with the ringing bell to call the operator. This allows you to know who is on the other end of the ringing phone, that is, the caller, and to answer calls that do not require a response. You can get the effect that you can do without it.
