Abstract

PURPOSE:To constitute the title system so that transmission side subscriber's information such as a subscriber's number and its address, etc., can be known by a voice before executing a response by a call signal by sending out a sound signal of the subscriber's information together with the call signal to an incoming side terminal equipment from an incoming side exchange. CONSTITUTION:When a speech path is set by the other station exchange 4 of an incoming side, a ringing tone for informing a fact that an incoming side terminal equipment 2 is being called is sent into a transmission side terminal equipment 1. On the other hand, at about the same time, to the incoming side terminal equipment 2, together with a call signal 22 outputted from a call signal trunk part 4C, transmission side subscriber's information such as a transmission side subscriber's number and its address, etc., is transmitted as a sound signal through a voice synthesizing circuit 7 from a receiving information storage means 6. Therefore, since the transmission side subscriber's information by a voice is outputted together with the call signal outputted from the incoming side terminal equipment 2, whether a response for executing a call to the transmission side is acceptable or not can be decided very easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone exchange system, and more particularly to a telephone exchange system configured to perform a connection operation between terminals based on a call from a calling side.

[Prior Art] In a conventional telephone exchange system, the calling side recognizes the subscriber number of the called party, makes a call from a terminal, activates the exchange, and then sends a dial signal for the subscriber number of the called party to the exchange. do. The exchange identifies the called terminal based on the dial signal, and sends a paging signal 11 to the called terminal (without information about the calling party). The exchange immediately establishes a connection between the calling and called terminals based on the response from the called terminal in response to the ringing tone.

[Problem to be solved by the invention]

However, in such conventional examples, the calling party can already identify the called party before making a call by indicating the subscriber number that recognizes the incoming signal. On the other hand, the called party
There has been a situation in which the calling party cannot be identified at the time of answering the call, and the calling party can only be identified and recognized during the mutual conversation after the call is answered.

In other words, with conventional exchanges, the receiving party was unable to identify the calling party by the ringing signal sent from the exchange via the terminal, and had to temporarily interrupt what they were doing to respond. .

[Purpose of the invention]

An object of the present invention is to improve the disadvantages of the conventional example, and in particular, to enable the called party to easily recognize the calling party before starting a call, thereby making it possible to selectively respond to calls by the calling party. It is an object of the present invention to provide a telephone exchange system that can effectively reject this.

(Means for Solving the Problems) In the present invention, a telephone connects a calling terminal and a called terminal via the exchange by transmitting a signal of the subscriber number of the called party from the calling terminal to the exchange. In the switching system, the local exchange to which the calling terminal is connected is equipped with subscriber information storage means for storing subscriber information regarding the calling terminal. A receiving information storage means for temporarily storing the subscriber information sent from the subscriber information storage means and a voice synthesis circuit for converting the subscriber information into an audio signal and outputting the same are installed in the other-office exchange. This system aims to achieve the above-mentioned purpose.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to FIG.

In the embodiment shown in FIG. 1, the transmitting terminal 89 receives a signal related to the subscriber number of the called party that is output from the calling terminal 1, and transmits the signal to the called terminal 2. It is equipped with

Of these, the local exchange 3 to which the originating terminal is connected is equipped with subscriber information storage means 5 for storing subscriber information regarding the originating terminal 1.

Further, the other-office exchange 4 connected to the receiving side terminal 2 includes a calling information storage means 6 for temporarily storing the subscriber information sent from the subscriber information storage means 5, and a calling information storage means 6 for temporarily storing the subscriber information sent from the subscriber information storage means 5. A speech synthesis circuit 7 that converts into a speech signal and outputs the signal is also provided.

To explain this in more detail, the local exchange 3 connects the outgoing signal 21 from the originating terminal 1 input via the changeover switch unit 3A and the changeover switch unit 3A to the connection within the own office or to another station. Outgoing register trunk section 3 that identifies the connection of
B, an outgoing sender trunk section 3C that temporarily stores the outgoing signal 21, and an outgoing trunk section 3D that sends the outgoing signal 21 to the other-office exchange 40 entry trunk section 4D.

In this case, when the outgoing signal 21 is identified by the outgoing register trunk unit 3B as one that should be connected to the other exchange 4, the outgoing signal 21, which is the subscriber number of the called party, is output. It is temporarily stored in the sender trunk unit 3 (1). Thereafter, the outgoing signal 21 is outputted from the outgoing trunk unit 3D to the other exchange 4.

Then, together with the subscriber number of the called party which is sent to the incoming trunk section 4D of the other exchange 4, the subscriber information of the calling party is transmitted via the outgoing trunk section 3D. The information is temporarily stored in the received information storage means 6 via the received information storage means 6. The subscriber information transmitted in this case is stored in advance in the subscriber information storage means 5 within the local exchange 2.

1 in the other exchange 4 on the receiving side, and outgoing trunk section 3 on the calling side
The receiving side subscriber number sent to the incoming trunk section 4D via D is received, and the communication path '' to the called side terminal 2 is identified and set.

Here, the other station exchange 4 on the called side has a switching section 4.
A, a ringing trunk section 4B, an incoming trunk section 4D, and a ringing signal l/rank section 4C attached to the changeover switch section 4A.

Next, when a call path is set in the other exchange 4 on the receiving side, the ringing trunk section 4B is activated immediately, and the ringing tone notifying the terminal 2 on the receiving side that the terminal 2 is being called is emitted from the large trunk section 4D. and is sent to the originating terminal 1 via the outgoing trunk section 3D.

On the other hand, around this time, the called terminal 2 receives a calling signal 22 outputted from the calling signal trunk section 4C.
Calling side subscriber information such as calling side subscriber number and address is transmitted as a voice signal from reception information storage means 6 via voice synthesis circuit 7.

Therefore, on the receiving side, the caller's subscriber information is outputted in voice form along with the ringing signal output from the called terminal a2, making it extremely easy to decide whether to accept or deny a response to the caller. can be done.

If the user does not wish to make a call, the call is switched to an answering machine or the call path is disconnected by reset. On the other hand, when a call is selected, the receiving exchange 4 detects this based on the response from the terminal 2. Subsequently, the trunk section 4D for the 21 terminals on the receiving side, the outgoing trunk section 3D, and the calling terminal N1 are connected, and the other trunks are disconnected.

By the above operations, the calling terminal 1 and the receiving terminal 2 are
It is possible to make calls between.

In the process of connecting the communication path between the calling terminal 1 and the called terminal 2, as mentioned above, the called party calls the calling party registered in advance in the exchange before responding to the calling party's call. Obtaining information by voice makes it easier to decide whether to accept or reject a call.

As a result, in telephone exchanges where the called party is called under the initiative of the calling party, the called party is able to know the calling party before the call, rather than knowing the calling party through the call, and it is possible for the called party to know the calling party before the call. can be placed in the position of Furthermore, the called party can reserve the right to make a call by obtaining materials for deciding whether to accept or reject the call.

〔Effect of the invention〕

As explained above, according to the present invention, the exchange is equipped with a function of presetting and storing subscriber information related to the calling terminal, and the subscriber information is sent to the receiving side exchange by a call from the calling terminal. By transmitting a voice signal of the subscriber information along with a paging signal from the terminating side exchange to the terminating terminal, the terminating side can transmit the subscriber number, address, etc. by voice before responding with the ringing signal. There is an advantage that side subscriber information can be known. This is because the calling party is in a leading position because it identifies the called party at the time of making a call by specifying the called party's subscriber number, whereas the called party is in a leading position before making a call with the calling party. This has the effect that the calling party can be identified by the subscriber information of the calling party stored in the voice exchange, and it is possible to decide in advance whether or not to accept the call. As described above, in the present invention, the called party can easily defend against a call connection request made by a unilateral call from the calling party, and the living rights of the called party are not violated. No better telephone exchange system can be provided.
