Abstract

PURPOSE:To display an outgoing number on an incoming side telephone set without requiring the change of an exchange by detecting the stoppage of a call tone when performing outgoing, sending its own telephone number in a PB signal, receiving the signal when receiving a response, and displaying a reception number. CONSTITUTION:When a telephone set 1-2 at an incoming side responds to a call signal, an incoming station 6 connects an input trunk 5 to a subscriber circuit 9 via a bus 62, and a speech path between the telephone sets 1-1 and 1-2 is formed. The telephone set 1-1 inputs the call tone to a detection circuit 11, and monitors the constant cycle of the tone, and when off-time exceeding a prescribed time is detected, it is judged as the response of the telephone set 1-2, and the formation of the speech path is recognized. Then, its own telephone number is read out from a number memory circuit 13, and the PB signal is generated by an outgoing circuit 12, and is sent out to an outgoing station 3. The signal is inputted to the telephone set 1-2 via the incoming station 6, and is displayed on a display circuit 15 as an outgoing number by a reception circuit 14. Thereby, the telephone number of an outgoing side subscriber terminal can be displayed on an incoming side subscriber terminal.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a calling number display telephone and a calling number display method, and particularly to a telephone number (
The present invention relates to a PB telephone that displays a calling party number (calling number) on a called subscriber terminal and a method for displaying the same.

[Conventional technology]

Conventionally, the method of displaying the calling number on the called subscriber's terminal is to send a PB double signal by manual operation of the caller's PB telephone after the called subscriber's terminal responds, or to send a PB double signal from the calling center's exchange. There are two methods for displaying the calling number on the called subscriber's terminal by modifying the number.

[Problems to be Solved by the Invention] The conventional calling number display method described above has the following drawbacks.

The former method involves a lot of effort on the part of the caller as the caller manually operates the PB telephone to send out his/her own telephone number to the receiving terminal \\, while the latter method requires a lot of effort on the part of the caller in the case of an intra-office call. This can be achieved by modifying the software, but in the case of ingress and egress connections, it is not economical as it requires modification of all switching equipment in the national network.

[Means to solve the problem]

The calling number display telephone of the present invention is a PB telephone that includes:
A number storage means for storing a predetermined own telephone number, and a telephone number stored in the number storage means for monitoring the ringing tone from the converter at the time of a call and detecting a stoppage.
It is provided with a number sending means for sending a B double signal to the exchange, and a number display means for receiving a PB double signal from the exchange at the time of response and displaying the received number.

In the calling number display method of the present invention, a switching system is configured using the calling number displaying telephone according to claim 1 as a subscriber terminal, and a call is made from the calling number displaying telephone of the calling party to the calling number displaying telephone of the called party. .

In this case, the exchange detects a response from the colored number display telephone of the called party, stops the ring tone to the calling party's calling number display telephone, and displays the calling number display telephone of the calling party and the called number display of the called party. When a call is established between telephones,
The caller number display telephone on the calling side sends out a predetermined own telephone number as a PB double signal, and the call receiver's call number display telephone receives the PB double signal and displays the corresponding telephone number.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a relay system diagram for explaining an embodiment of a switching system to which the present invention is applied. Calling number display telephone 1
-1.1-2 includes a ring detection circuit 11 that detects the presence or absence of a ring from the exchange, a number storage circuit J3 that stores its own telephone number (calling number), and a PB corresponding to the calling number.
A PB signal transmitting circuit 12 that creates a double signal and sends it to the exchange, and a P that receives the PB double signal from the exchange amount and outputs the received number.
B signal receiving circuit 14 and display circuit 1 for displaying received numbers
5.

A calling number display telephone 1-1 on the calling side is connected to a calling station 3 having an exchange through a subscriber circuit 2, and makes long-distance calls using an outgoing trunk 4. (not shown) and is connected to a terminating station 6 via an incoming trunk 5. The receiving station 6 has an exchange, connects the ringing sound source 7 to the incoming trunk 5 through a path 61, transmits the ringing tone and the calling number of the calling party to the display telephone 1-1, and at the same time connects the ringing signal source 8 through a path 63. It is connected to the subscriber circuit 9 and sends a calling signal to the calling number display telephone 1-2 on the called side.

Next, the operation will be explained.

In the state shown in Figure 1, the called party's calling number display telephone 1
-2 responds to the paging signal, the terminating station 6 releases the connection by the paths 61 and 63 and connects the large trunk 5 and the subscriber circuit 9 via the path 62. As a result, the sending of the ring tone to the calling number display telephone 1-1 on the calling side and the sending of the ringing signal to the calling number display telephone 1-2 on the called side are stopped, and the calling number display on the calling side and the called side is stopped. telephone 1
1. A communication path between 1 and 2 is formed.

The calling number display telephone 1-1 on the calling side inputs the ring tone to the ring tone detection circuit 1 and turns it on at a certain period (for example, 1 second on/off).
When the off time is detected to be longer than a predetermined time (e.g. 3 seconds), the calling party's calling number display telephone 1-2 responds and the connection of paths 61 to 63 is changed to terminate the call. Recognize that a path has been formed. Then, it reads its own telephone number (calling number) stored in the number storage circuit 13, creates a PB multiplied signal by the PB signal sending circuit 12, and sends it to the calling station 3. The PB double signal is input to the calling number display telephone 12 on the called side via the receiving station 6, and is displayed on the display circuit 15 as the calling number by the PB signal receiving circuit 14.

〔Effect of the invention〕

As explained above, the present invention provides a PB telephone with a means for detecting a ringing stop when making a call and transmitting a predetermined own telephone number (calling number) as a PB signal, and a means for receiving the PB signal when responding. By providing means for displaying numbers, it is possible to display the calling number on the called telephone terminal without requiring any changes to the existing exchange.
