Abstract

PURPOSE:To eliminate the need for a call signal generator and also to allow a called party to respond by a telephone set nearby by calling the called party from a speaker in voice formed by voice synthesis. CONSTITUTION:In transmitting a called extension number from a caller telephone set A, it is identified by a central processing unit 2 via a register 5, and the called extension number is transmitted to the voice synthesizer 7 via a signal line 21. The voice synthesizer 7 makes callout from a paging trunk 4 and the speaker 6 in a prescribed voice pattern, e.g., ''No.X, you are wanted on the telephone (repeated)'', and when the called party dials a prescribed incoming response number from a telephone set nearby, the connecting path is set via an intra-office trunk.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a called subscriber paging scheme in an automatic private branch exchange.

Conventionally, paging of a called party occurs as follows. When the calling party dials the odd number of the called party,
The signal corresponding to that dial is received at the register.

The control circuit identifies the signal in the register, selects the location of the called party contained in the storage device, and sends a paging signal (typically a 16-20 Hz alternating current signal) to the called party. .

This ringing signal causes the bell circuit of the called party's telephone to ring at an active level. This system is common to crossbar type exchanges and electronic exchanges, although the configuration of the control section and the switch differs. In other words, the conventional system requires a ringing signal power source (ringing signal generator) to ring the telephone's bell circuit, which complicates the ringing signal sending circuit and the called party's response monitoring circuit, making it difficult to reduce the cost of the device. It was a hindrance.

An object of the present invention is to provide a system that allows a called party to be called without sending a paging signal, and furthermore, to automatically control a series of operations related to calling a called party.

The present invention includes a central processing unit that detects a selection signal corresponding to a paging ring signal and a called party telephone number transmitted from a calling extension and stored in a register, and a selection signal that is output based on a control signal from the central processing unit. a speech synthesizer that converts the speech into a speech pattern and synthesizes the speech pattern with a predetermined speech pattern to create a desired speech pattern; and a speech synthesis device that receives a synthesized speech pattern signal from the speech synthesis device via a paging trunk; It consists of a paging device that sends out audio.

The structure of a called subscriber paging calling system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a paging calling system according to an embodiment of the present invention, showing a state in which a called subscriber is being paged. Further, FIG. 2 shows a state in which a calling subscriber and a called subscriber are connected. In Figures 1 and 2, A and B are extension telephones, 1 is a switch, and 2 is a central processing unit (CPU).
.

3 and 9 are subscriber circuits, and 4 is a paging trunk.

5 is a register, 6 is a paging device, 7 is a speech synthesizer, 8 is a paging trunk group, and 10 is a trunk within the own station.

The operation of the called subscriber paging system according to the embodiment of the present invention will now be described with reference to the drawings. When the caller takes off-hook, the central processing unit detects the call via the subscriber circuit 3 and connects the telephone set A and the register 5. The register 5 sends the calling party to the calling tone chemist A and receives from the telephone A a selection signal corresponding to the telephone number of the called subscriber. Signal path 20 to JrL
The selection signal in the register 5 transmitted to the central processing unit 2 at The signal is sent to the speech synthesizer 7. The voice synthesizer 7 converts the called subscriber information into a voice pattern of the corresponding called subscriber number, and synthesizes this with a predetermined calling voice pattern. At this time, the speech synthesizer 7 is connected to the paging trunk 4 via the switch 1. A synthesized voice pattern signal is sent from the voice synthesizer 7, and the synthesized voice is played via the paging device 6 (or speaker). For example, if the called subscriber number is "423"
”, and the predetermined voice pattern is 0 phone number, then the result of speech synthesis is ``423 phone number.'' (
(repeatedly),''.

When the called subscriber B completely off-hooks the receiver in order to answer this, it is detected by the subscriber circuit 9, and further dials a predetermined answering number (for example, the number "4").
The central processing unit 2 identifies this and connects the trunk 10 within its own station.
Connect telephone A and telephone mB via. In this way, both parties can talk over the phone (Figure 2).

If the called parties are scattered over a wide area and the voice from the paging device cannot reach them, install multiple paging devices as shown in Figure 2 and set a certain level of control for each paging device. It is also possible to adopt a system in which calling processing is performed only for subscriber groups. However, in areas with adverse environmental conditions, it is possible to use it in conjunction with conventional telephone ringing by ringing a bell circuit.

As explained above, according to the present invention, a paging power source (paging signal generator) is completely unnecessary, and the cost of the device for paging a called party can be reduced. Furthermore, since speech synthesis is performed automatically and accurately, the burden of labor can be reduced. Furthermore, it is convenient because even if the subscriber is not at his own telephone, he can answer the call at the nearest telephone.
