The present invention also relates to a telephone device having a function of displaying a corresponding display, and particularly relates to a button telephone device.

[Conventional technology]

Conventionally, for example, in a stand-alone telephone equipped with a billing display function, no matter how long the telephone line it has captured is put on hold, it will always answer again. The corresponding call charges etc. were displayed continuously.

[Problem that the invention seeks to solve]

However, in a key telephone device, a telephone that answers a telephone line in a hold state or a hold transfer state is not necessarily a hold operation telephone, and a fixed charge display is not displayed for a hold operation telephone as in a stand-alone telephone. Otherwise, inconvenience will occur if another key telephone responds.

[Means for solving problems]

A first button telephone device of the present invention includes a line state determining means for determining the state of a telephone line in which call information corresponding to call frequency or call duration is being accumulated, and based on the output thereof, it is determined that the telephone line is on hold. In this case, the integration operation of the call information integration means continues, but the display is interrupted.
and a control means for restarting the display on the answering telephone when answering on hold.

Further, the second button telephone device of the present invention includes a line state determination means, a response telephone determination means for determining whether the hold response telephone is a hold operation telephone, and a telephone line is on hold based on the output of the line state determination means. While the integration operation continues, the display is interrupted when
The present invention is further provided with a control means for newly integrating and displaying when the answer is a hold response from a telephone other than a hold operation telephone based on the output of the answering telephone determining means.

[Effect]

When the button telephone with a display device in the first button telephone device enters the calling state, the call information accumulating means starts accumulating and the display on the button telephone starts; however, when the button telephone is put on hold, the display is interrupted. Ru. Thereafter, when there is a hold response, the display is resumed for the answering telephone.

If a hold response is received from a button telephone with a display other than the hold operation telephone while the second button telephone device is on hold, the call information accumulating means starts a new accumulation operation, and a response is responded according to the content of the call information accumulation means.

On the other hand, the communication path switch 12 and the lines 3 ₁ to 3 _n from each handset 4 ₁ to 4 _n are connected via the telephone interface 13 (13 ₁ to 13 _n ), and the analog lines in the communication path switch 12 Exchange connections are made by cross points such as switches or relay contacts.

In addition, the outside line interfaces 11 ₁ to 11 _o are
It has functions such as detecting incoming calls, forming a DC loop for outside lines, holding calls, and dialing out calls using pulse signals or DTMF signals.
has an exchange connection function between the outside lines 2 ₁ to 2 _o and the handsets 4 ₁ to 4 _n and between the handsets 4 ₁ to 4 _n . Further, the telephone interfaces 13 ₁ to 13 _n supply telephone power to the handsets 4 ₁ to 4 _n via communication lines, transmit and receive data signals via signals, and supply control power to the slave units 4 1 to 4 n.

Furthermore, the main device 1 includes a processor unit 14 such as a well-known microprocessor, a fixed memory (ROM) 15 and a variable memory (RAM) 1.
A control unit consisting of 6 and a fixed memory 15 is provided.
The processor unit 14 executes a program stored in advance while accessing the variable memory 16 as appropriate, thereby controlling each section.

On the other hand, in each of the slave units 4 ₁ to 4 _n , a communication circuit 42 is connected to the communication line 41A. Further, the signal line 41B is connected via a transmission circuit 43 to a processor unit 44, which is similar to the control section of the main device 1, but smaller in scale, and a fixed memory 45A.
A control section consisting of a variable memory 45B is connected, and it emits an incoming ring tone in response to a control signal sent from the main device 1 via the transmission circuit 43, and also controls the sound in the keyboard 46 in accordance with a control signal from the main device. In addition to controlling the lighting, extinguishing, and blinking of each indicator light, operation data indicating these conditions is transmitted as specific code data via the transmission circuit 43 in response to the operation of each button on the keyboard 46 and the operation of the switch HS. and sends it to the main device 1.

Note that the transmission circuit 43 has a power supply separation function,
The power supplied from the main device 1 side via the signal line 41B is extracted, stabilized, and then supplied as local power V to each section that requires it.

In addition, in this embodiment, the specified handset 4 ₁ connected to the connector CN ₁ , that is, in the accommodation position "1" is a button telephone with a display, and has a multi-digit number (16 in this embodiment).
digit) is provided with a dot matrix type display 47,
Settings of various operational data that define the basic operation of the system are performed on this slave unit ₄₁ while looking at the display on the display 47. In general, the display 47 displays the outgoing dial during dialing, and displays the call charge after the called party responds, that is, after the first polarity change signal (charging signal) is detected, as will be described later.

In the above configuration, the main device 1 transmits and receives data to and from each of the slave devices 4 ₁ to 4 _n at regular intervals. Therefore, when off-hook is performed in any slave device, this operation data is received by the processor unit 14. The same applies to key input operations on the keyboard 46, and the processor unit 14 controls the call path switch 12 in accordance with the operations of the outside line button, extension line button, dial button, etc.
Make an exchange connection. At the same time, if you make an outside call,
The selected outside line interface 11 is controlled to make a dial call, and if the call is an extension call, an extension ring tone is emitted via the processor unit 44 of the slave unit on the other party's side, and the caller receives a response from the other party. If you do so, you will be in a talking state.

Further, incoming calls from the outside lines 2 ₁ to 2 _o are detected by the outside line interfaces 11 ₁ to 11 _o , and in response to this, the processor unit 14 connects the outside lines via the processor unit 44 of each handset 4 ₁ to 4 _n . Emit an incoming ringtone. If any handset responds with an off-hook, this causes the processor unit 14 to
controls the call path switch 12 and completes the call path.

Furthermore, even when a PB operation is performed to receive a bank service, a hooking operation is performed to receive a telephone service, the information is immediately stored in a buffer memory such as FIFO, and the information is immediately stored in a buffer memory such as a FIFO and controlled by the processor unit 14. are transmitted sequentially to the telephone line.

Here, the main device 1 is equipped with a billing signal detection circuit 17 (17 ₁ to 17 _o ) for each outside line 2 ₁ to 2 _o , which detects a charge signal to the telephone line at a cycle according to the dial destination. The incoming billing signal, that is, the polarity reversal signal is detected. Each detection circuit 17 has, for example, one
It consists of a light-emitting diode connected to only one of the pair of external line terminals and a unidirectional current detection circuit equipped with a photocoupler consisting of a phototransistor, so that the signal arriving at the telephone line is connected to either side of the external line terminal. Depending on whether the photocoupler is set as the positive electrode, the photocoupler is turned on or off, and outputs of different levels are sent to the processor unit 14.

Next, the operation of this embodiment will be explained using FIGS. 2 and 3.

FIG. 2 is a flowchart showing a billing signal detection processing program in the processor unit 14. The execution of the program shifts to this billing detection process in the outgoing call state.

In FIG. 2, when reception of a billing signal is detected (step 101), the RAM
Based on the contents of the circuit state memory provided using the 16 predetermined areas, it is checked whether there is a child unit currently being captured (step 102). If there is a handset that is being captured, it is further checked to see if it is deprioritized, which is used when holding a conference by connecting two or more extensions to one outside line (step 103). If the privacy is being released, the content of the charge counter provided using a predetermined area of RAM 16 is incremented by "1" for the calling handset, that is, the key telephone that captured the telephone line first, in other words, the telephone to be interrupted. (Step 104). Next, the call charge is displayed on the display 47 according to the content (step 105).
Since the charge counter of this embodiment counts the number of calls, that is, the number of arrivals of periodic charge signals, the call charge is calculated by multiplying the counted value by the unit call charge. The call charges may be integrated into the charge counter itself, and in this case, the integrated value is displayed as is.

If the private line is not being deprived (step 103), that is, if a normal outside line call is in progress, the content of the charge counter provided for the key telephone that is capturing the outside line is incremented by 1 (step 103).
106), the call charge is displayed on the display 47 of the handset in the same manner as described above (step 105).

If there is no handset currently in possession of the telephone line from which the billing signal has arrived (step 102), this indicates that the phone is on hold or is being transferred on hold. The contents of the charge counter are incremented (step 107).

If no billing signal is detected (step
101), and performs detection processing for other input signals (step 108).

Next, FIG. 3 is a flowchart showing a key input response processing program.

In FIG. 3, when key or switch operation information on any key telephone is received (step 201), the processor unit 14 executes the following operations based on the contents of a predetermined area of the RAM 16
It is checked whether the handset is acquiring an outside line (step 202). In the case that the outside line is being acquired,
When the call termination code is received (step 203),
Check whether the secret is being released (step 204),
In addition, if the confidential message is being deconfined,
Depending on the contents registered in the specified area of RAM16,
It is checked whether the handset is the key telephone that previously captured the outside line (step 205).

If it was the handset that captured the outside line first, clear the charge display of that handset (step
206), change the definition of interrupter to calling device (step
207). In other words, although the calling handset is registered in the line status memory for that external line, the data indicating the calling handset is rewritten from the data indicating the first interrupted telephone to the data indicating the interrupting telephone. .

Next, an outside line release process is performed for the interrupted telephone (step 208), and the charge counter for the new calling machine is cleared (step 209).

On the other hand, if the handset is not the handset that captured the outside line first, that is, if it is an interrupt telephone, an outside line release process is immediately performed for the handset (step 210).

In addition, if the confidential conversation is not canceled (step 204), the call is terminated by a simple on-hook, and the call immediately moves to the end process (step 204).
211). Furthermore, unless a call termination code has been received (step 203), other processing is performed in accordance with the received code (step 212).

If the handset is not acquiring an outside line (step 202), it is checked whether it is in an off-hook state (step 213), and if it is in an off-hook state, it is further checked to see if an outside line code is being received (step 214).
If an outside line code has been received, check whether the outside line is on hold from the registered contents of the outside line (step 215), and if the outside line is on hold, the handset performs a hold operation on its own. It is checked from the contents of the line status memory whether or not the key telephone has been used for a long time (step 216).

As a result, if it becomes clear that the telephone is on hold, the content of the charge counter is displayed on the display 47 of the handset (step 217), and the process of re-capturing the outside line that was on hold is performed (step 218). ).

If it is not a hold operation phone (step
216), clear the charge counter (step 219),
After clearing the memory in which the held telephone is registered for that outside line (step 220), a reacquisition process is performed (step 218).

If the outside line is not on hold (step 215), normal outside line key processing is performed (step 221). Also,
Unless an outside line code was received (step
214), and other processing corresponding to the received code is performed (step 222).

If it is not in an off-hook state, that is, if it is in an on-hook state (step 213), and if an off-hook code is received (step 223), the processor unit 14 further checks whether or not a pending transfer is being received (step 213). 224). As a result, if the transfer is being received on hold, the charge counter is cleared (step 225), the outside line that was on hold is captured (step 226), and the memory in which the transfer device was registered is cleared (step 225). 227).

If the pending transfer is not being received (step 224), the process immediately shifts to off-hook processing (step 228).
If an off-hook code has not been received (step 223), other processing is performed depending on the received code (step 229).

As a result, the billing display operation of this embodiment can be summarized as follows.

If a handset with a display device performs a hold operation while an outgoing call is being made to an outside line receiving billing service, the billing signal that arrives while on hold will continue to be accumulated for the holding device. , the price will not be displayed while the item is on hold. In this state, when the holding machine reacquires the held outside line, the charge display is resumed according to the number of calls accumulated up to that point.

If you perform a hold transfer to another handset while on hold, after the handset on the receiving side captures the held outside line, any billing signals that arrive thereafter will be transferred to the handset on the receiving side. The charges are accumulated and the charges are displayed on the handset on the transfer/receiver side accordingly.

If a handset equipped with a display device is making an outgoing call to an outside line that is receiving billing service, and a handset also equipped with a display device interrupts the call and enters the de-privacy state, the de-privacy state The charging signal that arrives during the interruption continues to be accumulated for the interrupted machine, and the charge display continues for the interrupted machine. after that,
When the interrupting device terminates, both the accumulation of billing signals and the display of charges continue as they are for the interrupted device. On the other hand, if the interrupted machine ends the call first, the integration of the number of calls and charge display for the interrupted machine will be terminated at that point, and the billing signals that arrive after that will be discontinued. For call machines, the number of calls will be added up and the charges will be displayed.

The above has explained hold transfers, interruptions, etc. between key telephones with display devices, but even if a key telephone device without a display device is involved, in that case, the key telephone device that should display the display also has a display device. If the display is not displayed, no display is actually performed, but the situation is exactly the same.

Furthermore, although the explanation has been given using an example of an outgoing call to an outside line receiving billing service, billing output may be generated at a cycle according to the dial destination within the system.

Furthermore, although the call charge is displayed as the billing display, the number of calls may be displayed as is. Further, the remaining time for each call may be displayed in parallel with these billing displays.

Although a charge counter for accumulating the number of calls is provided for each key telephone, it may also be provided in common. Also,
In addition to such a charge counter, a counter may be provided that cumulatively holds the total number of calls or the total call charge for each key telephone.

The explanation has been given using examples such as hold and hold response, hold transfer and transfer response, but the same applies to automatic transfer, etc., and regardless of the operation method, it can be applied in the same way as long as the telephone line is put on hold.

Although the case of charge display has been described above as an example, the present invention can be similarly applied to the display of cumulative call time when a telephone line is captured or on hold. In this case, it is equipped with a call time counter that starts when the called party's response (reversal signal) is detected and measures the elapsed time, and the call time display according to the contents of this counter is interrupted while the phone is on hold, and the call time is displayed on the hold phone. If the answer is answered, the display will be resumed, and if the answer is answered by another telephone, a new measurement will be started from that point and displayed on the answering telephone, and if the privacy is canceled, the display will continue to be displayed on the interrupted telephone. If the interrupted telephone ends the call first,
A new measurement is taken from that point and displayed on the interrupt telephone.

〔Effect of the invention〕

As explained above, according to the present invention, based on the line status determining means and its output, the call information accumulating means continues the integration operation while on hold, but the display is interrupted, and when the call information is answered on hold, the answering telephone By providing a control means for restarting the display, or based on the line status determination means, answering telephone determination means, and the outputs of these means, the integration operation continues while the system is on hold, but the display is interrupted. By providing a control means for newly accumulating and displaying information at the time of a hold response from a telephone other than a holding operation telephone, call information can be displayed flexibly in response to changes in the line capturing telephone.
