Abstract

PURPOSE:To call an extension subscriber repetitively in a clear voice including an extension subscriber number by sounding externally information including a preset extension subscriber number in voice when an extension subscriber telephone set detects the arrival of a call based on a call signal from a private branch of exchange. CONSTITUTION:An extension subscriber number of an extension subscriber telephone set is set in advance by an extension subscriber number setting switch 1. While the extension subscriber telephone set is hooked on, when a call signal comes from a private branch of exchange 9 based on the arrival of a call to the extension subscriber telephone set, the call signal is detected by an incoming call detection circuit 6 to detect the incoming call state. A voice synthesizer acquires voice information corresponding to a digit number A from a voice parameter storage ROM 3 when a head address corresponding to the digit number A from an incoming call display control circuit 2 and synthesizes a voice signal corresponding to the digit number A and the voice signal is sounded externally from a speaker 10 via an amplifier 5. Thus, the extension subscriber is called in a clear voice sound including the extension subscriber number.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a telephone set housed in a private branch exchange, that is,
A method for calling an extension subscriber in which, when calling an extension subscriber telephone, the extension subscriber number assigned to the extension subscriber telephone is externally displayed as voice, and a method relating to the extension subscriber telephone. It is.

[Prior Art] Up to now, when an extension subscriber's telephone receives a call, the extension subscriber is called only by a ringing sound or a tone ringer sound.

According to Japanese Unexamined Patent Publication No. 2-22952, when an extension subscriber receives a call, a message to that effect including the extension subscriber number is displayed externally.

[Problems to be Solved by the Invention] However, in the case according to the above publication, it is necessary for the extension subscriber to record the extension subscriber number in a non-standard voice for each extension subscriber telephone, for example. Not only may the voice be reproduced indistinctly, but also operational and psychological burdens cannot be avoided when recording an extension subscriber number as voice.

On the other hand, as a function of a private branch exchange, when a call is made to the telephone of the extension subscriber nearest to the seat where the user is absent, the call is received by the telephone of the extension subscriber closest to the seat using the special number and the extension subscriber number. However, if the extension subscriber number is not known immediately, the call cannot be answered immediately. As stated in the above bulletin, when a call is made using an extension subscriber number, the call can be forwarded by listening to the extension subscriber number, but in this case, the voice may become unclear. When played back, it is difficult to identify the extension subscriber number from the sound.

A first object of the present invention is to provide an extension subscriber calling method that can call each extension subscriber with a clear voice that includes the extension subscriber number when a call is received to each extension subscriber. be.

A second object of the present invention is to provide clear voice communication to each extension subscriber, including the extension subscriber number, until a call is received from the extension subscriber. To provide a method for calling an extension subscriber that can be called repeatedly.

A third object of the present invention is to provide an extension subscriber telephone set in which it is not necessary for each extension subscriber to record voice including the extension subscriber number.

[Means for Solving the Problems] The first object is to set information including the extension number on each extension subscriber telephone based on the voice parameters, and then transmit information from the private branch exchange to the extension subscriber telephone. This is achieved by externally displaying information including a preset extension subscriber number based on the calling signal (if an incoming call is detected).

The second purpose is to detect an incoming call based on a ringing signal from a private branch exchange on each extension subscriber telephone after information including the extension subscriber number is preset on each extension subscriber telephone based on voice parameters. This is achieved by repeatedly externally displaying information including a preset extension subscriber number while the incoming call is continuously detected.

Furthermore, the third purpose is to provide an incoming call detection circuit that detects a calling signal from a private branch exchange in an on-hook state, an extension subscriber number setting switch that sets the extension subscriber number as updatable, and a device that stores voice information in units of words. a voice synthesizer for synthesizing the voice information, a speaker for externally displaying the synthesized voice information in the form of voice, and an incoming call detected from the incoming call detection circuit. This is achieved by including at least an incoming call display control circuit that controls the voice synthesizer to sequentially read voice information including an extension subscriber number.

[Operation] The point is that information including the extension subscriber number is preset in each extension subscriber telephone based on the voice parameters. In this state, if an incoming call is detected on the extension subscriber's phone, information including the preset extension subscriber number or clear voice will be displayed externally, and the extension will be connected from that display. Once a subscriber has identified an extension subscriber's telephone, he or she can easily know that the extension subscriber's telephone is in a receiving state. Further, in this case, if information including the extension subscriber number is repeatedly displayed externally while incoming calls are continuously detected, reliable incoming call display can be performed.

Furthermore, as an extension subscriber telephone, when a calling signal from the private branch exchange is detected by the incoming call detection circuit in the on-hook state, the extension subscriber number setting switch is set in advance under the control of the incoming call display control circuit. Based on the extension subscriber number, the voice information corresponding to the extension subscriber number is sequentially read out from the voice parameter memory and then displayed externally from a speaker via a voice synthesizer.

[Example] Hereinafter, the present invention will be explained with reference to the accompanying drawings.

The figure shows the internal structure of an extension subscriber telephone according to the present invention together with a private branch exchange. As shown, the extension subscriber's telephone is connected to a private branch exchange 9 via a hook switch 11. While the extension subscriber's telephone is in the on-hook state, the hook switch 11 is connected to the incoming call display section according to the present invention, which includes the incoming call detection circuit 6, while in the off-hook state, the hook switch 11 is The switch 11 is connected to the communication circuit 12 and the handset 13 side.

Now, the incoming call display unit in this example includes an extension subscriber number setting switch 1, an incoming call detection circuit 6, an incoming call display control circuit 2, an audio parameter storage ROM 3, an audio synthesizer 4, an amplifier 5, a speaker 10, and a control work RAM 7. and control ROM8
By such a configuration,
When there is a call signal from the private branch exchange 9, this is detected as an incoming call, and information including the extension subscriber number is displayed externally as voice, allowing the extension subscriber to subscribe to the extension. This makes it easy to know that the extension subscriber telephone associated with the subscriber number is receiving a call. When an extension subscriber's telephone receives a call, for example, A, B, and C are output from the speaker 10.

Each D displays the digits of the subscriber's extension number, and an incoming call is indicated by voice, such as "Calling ABCD."

Here, the operation of the extension subscriber telephone set as described above will be explained. Prior to the operation, the extension subscriber number for the extension subscriber telephone set is set by the extension subscriber number setting switch 1. It has become a necessity. In this example, the extension subscriber number setting switch 1 is 1
It is composed of 6 bits, and is divided into 4 bits to make up the 4-digit extension subscriber number A.
.

Each of B, C, and D is set to be BCD coded.

Now, while the extension subscriber phone is on hook,
When a ringing signal is received from the private branch exchange 9 based on an incoming call to the extension subscriber's telephone, the ringing signal is detected by the incoming call detection circuit 6, thereby detecting the incoming call state. When an incoming call state is detected, the incoming call display control circuit 2 performs a predetermined incoming call display control.

That is, when controlling the incoming call display by the incoming call display control circuit 2, the extension subscriber number "ABCD" set in the extension subscriber number setting switch 1 is first read. After that, the digits read A, B, C, D
By referring to the control ROM 8 using each as an address, the start address in the audio parameter storage ROM 3 in which audio information corresponding to the digit numbers A, B, C, and D is stored is obtained, and the starting address in the control work RAM 7 is obtained. Digit number A
, B, C, and D are stored in the corresponding setting address areas. In addition, regarding the extension subscriber number "ABCD" followed by "It's a call to ni", the voice information corresponding to the words that constitute it is stored in the voice parameter storage R.
Since the starting addresses in OM3 are known in advance, these starting addresses are stored in the control work RAM 7 in predetermined address order following the setting address areas corresponding to digit numbers A, B, C, and D. It has become.

After the starting addresses are stored in the control work RAM 7 in a predetermined order as described above, the starting addresses are sequentially sent to the speech synthesizer 4. In the voice synthesizer 4, for example, when the head address corresponding to the digit number A is sent from the incoming call display control circuit 2, the voice information corresponding to the digit number A is obtained from the audio parameter storage ROM 3, and the voice information corresponding to the digit number A is obtained from the voice parameter storage ROM 3. After the audio signals are synthesized,
The signal is displayed externally as audio from a speaker 1o via an amplifier 5. When the external display of the voice corresponding to the digit number A is completed, an external display end signal is sent to the incoming call display control circuit 2, and then the start address corresponding to the digit number B is sent to the speech synthesizer 4. It is processed in the same way. From now on, the same process is repeated from the first address corresponding to the digit number C to the first address corresponding to "desu", and an incoming call is displayed with a series of voices "A, B, there is a call to CD". .

Even after the incoming call is displayed with this series of voices "ABCD is calling," as long as the incoming call detection circuit 6 continues to detect the ringing signal, the series of voices "
The incoming call message "A call to ABCD" is repeatedly displayed.

On the other hand, if the extension subscriber picks up the handset 13 and answers the call while the incoming call is being displayed with a series of voices saying "There is a call to ABCD", the hook switch 11 is shifted to the off-hook state, and the call circuit By connecting to the 12 side, it becomes possible to make a telephone conversation with the other party.

[Effects of the Invention] As explained above, in the case according to claim 1, when a call is received at the extension subscriber number, the extension subscriber is called with a clear voice that includes the extension subscriber number. In addition, in the case according to claim 2, when an incoming call is received at the extension subscriber's number, the extension subscriber including the extension subscriber number is sent until a response is received from the extension subscriber. It is possible to make repeated calls with clear voice, and according to claim 3, it is not necessary for the extension subscriber to individually record the voice containing the extension subscriber number on the extension subscriber telephone.
