Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone terminal device control system for a telephone exchange system.

[0002]

2. Description of the Related Art Conventionally, in a telephone with a built-in speaker, as a method of announcing a voice message from the speaker, an operator operates a speaker driving button provided on the telephone to operate the speaker.

Further, in order to announce the voice signal from the exchange from the speaker of the telephone, there is a method in which the speaker built in the telephone is directly connected to the telephone line when the telephone is not in use. It was A technique related to this is disclosed in Japanese Patent Laid-Open No. 206206/1982.
The gazette is mentioned.

[0004]

In the former case of the above-mentioned prior art, unless the operator calls the telephone and the operator does not respond to it, the announcement from the exchanger cannot be output from the telephone, and the latter. In the above, the announcement from the exchange can be always output from the telephone, but since the speaker is always connected to the line, there is a problem that the line noise is output from the speaker.

In view of the above problems, the present invention provides a control method of a telephone terminal device in which a speaker is driven only when an announcement signal from an exchange is output from a speaker of a telephone, and the speaker is normally turned off. The purpose is to do.

[0006]

According to the present invention, there is provided a telephone terminal device and a switching device accommodating the telephone terminal device, wherein the telephone terminal device includes a speaker and speaker driving means for driving the speaker. Control means for controlling the speaker driving means based on information received from the exchange device.

[0007]

With such a configuration, the speaker of the telephone can be normally turned off and the speaker can be driven only when the announcement signal from the exchange is output from the speaker of the telephone.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a system configuration diagram of a telephone exchange showing an embodiment of the present invention. It is assumed that the telephone 1 is provided with calling codes (numbers) "T1", ... "Tn", respectively. An individual calling code (number) "P1", ... "Pm" is given to an individual who uses the telephone. However, this does not mean that the calling code (number) must be given to all the telephones and all the users, and the calling code (number) may be determined according to the operating method of the system.

For example, assume that the telephone exchange system shown in FIG. 1 is a private telephone exchange system, and for convenience, all telephones and all users are given numbers, and m> n. T1 to Tn are conventional telephone numbers given to extension telephones, and when this call is made, it becomes a station call which is called only by a calling signal as usual. P1 to Pm
Is a number given to each user, and which telephone is to be called is registered in advance. Here, since m> n, there may be two or more individuals calling from the same telephone. When the calling party calls the called party with a personal calling number P ~,
A call is made by connecting to a telephone having the registered number, but since the exchange can recognize the called party from the numbers P to, for example, a call as shown in FIG. 2 is made.

[Lean ... "I'm calling XX. "... Lean ...""I'm calling ○○. "" That is, it is possible to notify to whom the call is made by announcing the called party name at the silent time of the conventional ringing signal by the bell. Therefore, even when two or more numbers are registered in the same telephone, it is possible to know who the call came from during the call.

Here, two kinds of numbers, T ~ and P ~, are provided. For example, when a person wants to call a certain section or a staff member and who can answer, the person is called with the number T ~, and a specific number. When it is desired to talk to an individual, the person may call by using the number P-, and when making all personal calls, the number T- need not be provided.

A more specific operation of the telephone exchange system will be described below with reference to the drawings. First, a description will be given of a first embodiment in which the announcement information is converted into an analog voice signal by the exchange and sent to the telephone.

In FIG. 1, a calling party P1 is called a telephone T1.
From the telephone Tn to call the called party Pm. When the calling party P1 raises the handset of the telephone set T1, the central control unit 6 detects this, and a so-called dial tone connection is made by the program stored in the storage unit 4. The calling party P1 is not shown in the figure. The circuit emits a dial tone. When the calling party P1 hears the dial tone, the number "Pm" of the called party Pm is received.
Dial. Central control unit 6 is called number "Pm"
6 (601 in FIG. 6), the called telephone number Pm is converted to the called telephone Tn using the "calling telephone registration table" stored in the storage device 4, and the called telephone to be connected is identified. To do. At the same time, it is checked whether or not the called telephone is busy, and if it is recognized that it is empty, the operation proceeds to the next operation (602 in FIG. 6).

In parallel with this, the central control unit 6 converts the called party number into a called party name XX by the "callee number-called party name conversion table" stored in the storage device 4. (FIG. 6, 603). This conversion is indispensable in the case of rule synthesis, but it is not always necessary in the case of waveform synthesis, parameter synthesis, etc., because the voice information can be obtained directly from the called number using the voice file. .

Upon confirming that the called telephone is free, the central control unit 6 selects an empty voice call trunk 7 (see FIGS. 6 and 6).
04), the called telephone Tn and an empty channel of the empty voice trunk 7 are selected (605 in FIG. 6), and these are connected (606 in FIG. 6). Needless to say, a ringing tone is sent to the calling telephone set by a circuit (not shown).

The central control unit 6 which has converted the called party number Pm into the called party name ◯◯ is the voice information corresponding to the called party name “◯◯” from the voice information file 5 and the called party call. Therefore, the voice information corresponding to "Call me ..." is extracted and edited (Fig. 6, 607). here,
In the case of waveform synthesis, the voice information is sampled digital information such as a PCM code, or band-compressed information thereof, and in the case of parameter synthesis, for example, the voice is a PA.
It is a parameter of RCOR analysis. The voice information edited in this way is transferred to the voice call trunk 7 to which the called telephone is connected (608 in FIG. 6) and stored in the memory in the trunk. In the voice call trunk 7, the stored voice information is read at a constant cycle and at a constant speed and converted into analog voice information by a demodulator or a voice synthesizer.
In the time relationship shown in (6), the call signal is alternately transmitted to the telephone set Tn through the switching network 3 (609 in FIG. 6).

Here, the ringing signal may be a conventional alternating current for an electromagnetic bell or a tone ringer signal such as a single tone, a melody, a chime, etc. However, considering that the telephone has a voice ringing function, the tone ringer may be used. It is more technically compatible with the use of signals. It is also possible to call using only the voice signal without using the call signal, but here, in order to draw the callee's attention, the combination with the call signal has been described as an example.

The above embodiments have been described on the premise of an analog exchange, and the case where the voice call trunk is converted into an analog signal and transmitted, but in the case of a digital exchange, waveform synthesis is adopted and the sampling period is changed. If the encoding method is adapted to that of the exchange, the voice call trunk 7 receives the stored voice information as digital information as it is, and successively outputs it to a designated time slot, whereby the analog signal is transmitted. The same effect as in the case of the exchange can be obtained. Where 8 KHz sampling,
Let us roughly estimate the memory capacity of a voice call trunk in the case of an 8-bit coded digital system. For example,
Assuming a 4-second announcement, the memory requirement is 8
KHz × 8bit × 4sec = 256Kbit,
One 256Kbit RAM is enough to withstand practical use.

Next, the operation on the telephone side will be described.

The telephone has an amplifier 1-1 as shown in FIG.
6, speaker 1-17, and ringing signal detection device 1-1
8 and is always connected to the line as shown in the figure through the break contact of the contact HS of the hook switch that operates when the handset is lifted. The gain of the amplifier 1-16 is constantly kept low enough to prevent noise from the line from being heard from the speaker 1-17.
Call signal detection device 1 when a call signal is sent from a route
-18 detects this. The call signal is, for example, 16H
In the case of z and 75 VAC, the amplifier 1-16 of FIG. 3 is turned off while the ringing signal of FIG. 2 is continued. The ringing signal causes a bell to ring in a circuit not shown. In FIG. 2, when one ringing of the ringing signal is completed, the ringing signal detecting device 1-18 increases the gain of the amplifier 1-16 to a predetermined level, and the personal name announcement signal sent subsequently is a speaker. It will be broadcast and broadcast from 1-17. When the ringing signal detection device 1-18 detects the next ringing signal, the amplifier 1-16 is turned off again, the gain is increased at the end of the ringing signal, and this is responded (operation of the hook switch HS) or abandoned. Repeat until (the ringing signal does not come for a certain period of time).

When the ringing signal is a tone ringer, the ringing signal detecting device 1-18 detects the ringing signal and the amplifier 1 at the same time.
The gain of -16 is increased and both the calling signal and the announcement signal are broadcast from the speaker 1-17.

As described above, by using the telephone as shown in FIG. 3, the information about the call can be broadcast by voice in response to the operation of the exchange described above.

Next, as a second embodiment, an example in which voice information is transferred to a telephone in the form of digital data, the telephone stores the information, the voice synthesizer converts the voice into voice, and the broadcast is described. .

As an example of a telephone used in this case,
FIG. 4 shows an external view and FIG. 5 shows a configuration diagram. As for the connection between the telephones, it is assumed that the calling party P1 makes a call using the telephone set T1 and calls the called party Pm from the telephone set Tn, as in the first embodiment.

When the handset of the telephone T1 is lifted, the telephone controller 1-13 shown in FIG. 5 detects this (not shown) and sends a calling signal to the exchange through the line interface 1-12. In the case of this telephone, it is assumed that it is connected to the exchange through two pairs of cables for calling and data. Figure 1
In the exchange shown in, through the telephone interface 2,
The central control unit 6 detects this, makes a so-called dial tone connection, and causes the calling party P1 to hear the dial tone. The calling party P1 dials the called party number Pm after confirming the dial tone.

The called party number Pm is the push button dial 1 in FIG.
-2, and the telephone control device 1-13 receives it via the input / output interface 1-11. The telephone control device 1-13 transfers the number Pm in the form of digital data to the exchange through the line interface 1-12. In the exchange, the central control unit 6 receives this through the telephone interface 2 (701 in FIG. 7), and uses the "callee number-callee name conversion table" stored in the storage device 4 to identify the callee number Pm. The called party name is converted into XX (702 in FIG. 7). Then, the name of the called party "○○"
Is converted to the corresponding voice information using the voice information file 5, for example, the parameters that have been analyzed and stored in advance, and since it is the call to the called party, for example, "Call ......". The corresponding voice parameters are taken out from the voice information file 5 and edited so as to announce both (703 in FIG. 7). In parallel with this, the central control unit 6 identifies from the called party number Pm that the called telephone set is Tn using the "calling telephone registration table" stored in the storage unit 4, and further It is checked whether the called telephone Tn is in use, and if it is free, the next operation is performed (704 in FIG. 7). That is, the central control device 6 transfers the voice information edited to announce the called party name to the telephone 1 in the form of digital data via the telephone interface 2. In the telephone 1, the telephone controller 1 is provided through the line interface 1-12 in FIG.
-13 receives this and stores it in the storage device 1-14. The telephone control device 1-13 first instructs the voice synthesizer 1-15 to output the calling signal in order to send the calling signal and the announcement signal in the time relationship shown in FIG. The voice synthesizer 1-15 synthesizes a ringing signal for a fixed time according to the instruction and transfers it to the amplifier 1-16. The amplifier 1-16 amplifies this to a predetermined size and drives the speaker 1-17 to broadcast. To do. When the announcement signal transmission timing shown in FIG. 2 is reached, the telephone control device 1-13, the storage device 1-14.
Then, the previously stored announcement signal is read out, transferred to the voice synthesizer 1-15, and the announcement is instructed. The voice synthesizer 1-15 synthesizes the original voice from the received announce signal, that is, the parameters of the announce voice, and the amplifier 1
It is amplified by -16 and broadcast from the speaker 1-17. A person around the called telephone Tn knows that the call is received by the first ringing signal, and then hears "Call Mr. XX.", Which is subsequently broadcast, and knows that the called party is Pm.

Although the above example is the case of notifying the name of the called party, it is also applicable to the case of notifying the name of the calling party. That is, it is assumed that the user of the telephone has an identification card (ID card) that stores an individual identification code (ID code) or a personal name code, and calls using a telephone having an ID card reading function as shown in FIG. It shall be. In FIG. 4, the caller inserts his / her ID card 1-3 into the ID card reader 1-4, and then picks up the handset 1-1.

In FIG. 5, when the ID card 1-3 is inserted into the ID card reader 1-4 (801 in FIG. 8), I
The D card reader 1-4 reads the ID code from the ID card 1-3, and the read code is the telephone controller 1-
The data is transferred to and stored in the storage device 1-14 through the input / output interface 1-11 under the control of 13 (FIG.
2). Then, when the handset 1-1 is lifted (see FIG.
3), the telephone control device 1-13 detects this by a circuit (not shown) (804 in FIG. 8), reads the caller's ID code previously stored in the storage device 1-14, and makes a call. The information is transferred to the exchange through the line interface 1-12 (805 in FIG. 8). In the exchange, the central controller 6 of FIG. 1 receives it through the telephone interface 2 and
While the ID code is stored in the storage device 4, a dial tone connection is made according to the calling information. The called number is dialed, and the ID code is converted into the calling name at the same time as the conversion in the steps of FIG. 6 and 603 or the step of FIG. 7 and 702, or when there is no called party announcement. However, by editing the content of the announcement so that it corresponds, the calling party name can be announced by the same operation as described with reference to FIGS. 6 and 7. As the ID code, the individual numbers P1 to Pm may be used as they are or may be different.

The above is the case of announcing the name of the calling party and the name of the called party during the call, but it is also possible to announce information about the call other than the name such as the urgency of the call and the speaker during the call. It is also possible to make an emergency call or inform the call waiting.

In the above embodiment, the case of making an announcement to the called party is explained. However, the calling state (information about the call) can be similarly notified to the calling party. That is, the called party is busy, the line is busy, absent, rejected, etc.
The call state can be notified to the caller by editing the call state into voice information by the voice synthesizer and making an announcement to the caller. In this case, the announcement may be made from the handset of the telephone.

[0031]

According to the present invention, the speaker of the telephone is normally turned off, and the speaker can be driven only when the announcement signal from the exchange is output from the speaker of the telephone. It has the remarkable effect of making you feel uncomfortable.
