JPS61164363A - Private branch exchange - Google Patents

Abstract

PURPOSE:To attain call back soon even when a call is finished just before a reply by designing the titled exchange that a voice telling a caller is used so as to recognize the caller before the reply. CONSTITUTION:When a call is made from an extension circuit 6 to an extension circuit 5, a controller 2 checks a storage device 3 as to whether the extension circuit 5 is an extension registered with a voice call or not. When the vice call is registered, a prescribed voice is synthesized and sent to an extension terminal device 9 via the extension circuit 5, while the information such as the extension number of the extension circuit 6 or installed location is sent to a voice synthesizer 7. The voice signal passes through a hook switch 13 in the extension terminal device 9 and is inputted to a bell 2 and a high pass filter 15, but the level of the voice signal is kept to a small level so as not to drive the bell 12, then it does not ring. The voice signal is amplified by an amplifier 16 and outputted from a speaker 17.

Description

[Detailed description of the invention] Regarding private branch exchanges.

(Example) Conventional technology Traditionally, incoming calls to each line have been notified by ringing J%L* using a ringing signal from a private branch exchange. Japanese Patent Application Laid-Open No. 59-39154 as a device for calling by voice in place of a telephone bell.
There was a caller, but it just notified me that there was an incoming call, and I didn't know who was calling until I answered. Therefore, even if the call was cut off just before the call was answered, it was impossible to fix the call back.

C) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned points.The present invention is made in view of the above-mentioned points, and calls are made with a voice that informs the calling party, and the called party is made aware of the calling party before answering. The purpose is to

2) Means for solving the problem The present invention provides a calling signal generating means for driving a bell;
It has means for synthesizing a voice that informs the caller and a means for selecting one synthesized voice, and can make a call with only Kameyama for calling or with the voice that informs the caller.

), a bypass filter (15) for removing low frequencies including the 16IiZ calling signal, an amplifier α6 for amplifying the synthesized voice, and a speaker α. (1) is a communication path device that connects the lines, (2) is an S1j control device that controls the entire exchange including voice calls, and (3) is the control device (2).
), and (4) is a storage device in which control information from the control device (2) is stored, and (4) is a paging signal generator that generates a 16 Hz signal in order to distribute the operation command information from the control device (2) to the target device. Figure 2 is an example of the voice output from the voice synthesizer @(7).
Consists of a first category of voice that is stored in advance for each extension and synthesized using data from the control device (2), and a second category of voice that is synthesized regardless of the data and is output following the first category of voice. .

An extension desiring a voice call registers that fact using a special number dial provided for registering a voice call. When a call is made from the extension circuit (6) to the extension circuit (5), the control device (1) checks the storage device (3) to determine whether or not the extension circuit (5) is an extension that has registered a voice call.
Find out. If the voice call is registered, it is sent to the extension number of the extension circuit (6) or the installation unit spring terminal +91. At this time, the extension circuit (6) is connected to the communication path device (1).

If the signal is modulated at 16 Hz, it will be input to the electrolytic corrosion (2) and the bypass filter b), but if the level of the audio signal is kept low enough not to drive the bell bell, then the bell bell will not ring. There isn't.

On the other hand, the audio signal passing through the bypass filter is sent to the amplifier α6. The signal is amplified by the speaker (17) and outputted from the speaker (17). In addition, if the voice call is not registered, or if it is registered but the information of the caller (in this case, the extension circuit (6)) is not stored, the call signal and the electrolytic decoy will sound. , the 16 Hz calling signal is blocked by the bypass filter α5), and nothing is output from the speaker αη.

g) Effects of the Invention As is clear from the above explanation, in the present invention, a call can be made with a voice that announces the caller, so the caller can be known before answering, so even if the call is cut off just before answering, there is no need to worry. I can return the call and fix it.
