Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a button telephone device.

[Prior Art] Conventionally, in a key telephone device, when a hooking operation is performed to answer a call or to reacquire the same line, it is necessary to display the busy status of the outside line on other handset units during the hooking operation. , when on-hook information is received from a key phone during an outside line call, it is sent to all handsets for a certain period of time.
For example, the outside line was detected (busy) by lighting up the corresponding outside line lamp.

[Problem that the invention attempts to solve]

For this reason, even when you simply take off the hook at the end of the episode,
There is a problem in that the corresponding outside line lamp does not turn off until the above-mentioned certain period of time has elapsed, making the user feel uneasy.

[Means for solving problems]

The present invention uses the on-hook information from the key phone during an outside line call to display the opening of the corresponding outside line on the hooking operation button phone, and also uses the off-hook information while the hooking timer activated by the on-hook information is operating. The hooking operation button telephone set is provided with display control means for displaying the acquisition of the corresponding outside line.

[Effect]

In response to on-hook information from a key phone during an outside line call, including the case of ending a call, the outside line is released and the hooking timer is activated, but at the same time, the key phone is set to, for example, turn off the corresponding outside line lamp. A display indicating that the corresponding outside line is open will be displayed. If there is off-hook information while the above-mentioned hooking timer is operating, the released outside line is recaptured and the hooking information is sent to the outside line, and at the same time, the above-mentioned footing operation button telephone sets the relevant outside line lamp to turn on again. A display indicating that the corresponding outside line has been captured is displayed.

〔Example〕

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, 1 indicates the main device. This main device 1 is connected to an external line 2 such as a central office line from a telephone office or a telephone line from a private branch exchange via external line terminals L (L ₁ to _Lo ).
(2 ₁ to 2 _o ) are connected, and the connector CN
(CN ₁ to CN _n ) and one pair of communication lines and signal lines 3 (3 ₁ to 3 _n ) to key telephones (handsets) 4 (4 ₁ to 4 _n ),
Outside line 2 ₁ to 2 _o are each outside line interface 1
1 (11 ₁ to 11 _o ) to the communication path switch 12 . 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 signals using pulse signals or composite audio frequency signals.
2 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 power for telephone calls to the slave units 4 ₁ to 4 _n via communication lines, and also transmit/receive data signals and supply power for control via signal lines. Do this.

These controls are carried out by a control section consisting of a processor unit 14 such as a well-known microprocessor, a fixed memory (ROM) 15, and a variable memory (RAM) 16, which executes a program in the fixed memory 15 to the processor unit. 14
This is performed by executing predetermined data while accessing the variable memory 16.

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 in response to a control signal sent from the main device 1 via a transmission circuit 43, an incoming ring tone is emitted and each indicator light consisting of, for example, a light emitting diode in the keyboard 46 is controlled. In addition to controlling the lighting, turning off, and blinking of the lights, operation data indicating these conditions is transmitted to the main device 1 via the transmission circuit 43 in accordance with the operation of each button on the keyboard 46 and the operation of the switch HS. do.

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

In addition, in this embodiment, the slave unit (specific slave unit) 4 connected to the connector CN ₁ , that is, the housing position “1”
Reference numeral ₁ denotes a button telephone with a display device, which is equipped with a display device 47, and various operational data settings for operating the system can be set using the display device ₄ in this slave device 41.
This is done one by one for each item while looking at the display 7.

In the above configuration, the main device 1 sends and receives data to and from each of the slave devices 4 ₁ to 4 _n at regular intervals, then analyzes the received data, and accordingly,
Performs various control processing. For example, when off-hook is performed on 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., and performs exchange connection. At the same time, if it is an outside line call, the selected outside line interface 11 is controlled to make a dial call,
If the call is from an extension, an extension ring tone is emitted via the processor unit 44 of the slave device on the other party's side.
If there is a response from the other party, the call status is established.

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.

Next, using the flowcharts of FIGS. 2 and 3, the received data processing in the processor unit 14 will be explained, particularly focusing on the portions related to hooking.

In FIG. 2, the processor unit 14 is
Based on the contents of the status memory provided using a predetermined area of the RAM 16, it is determined whether or not the handset is on an outside line call (step 101). If the handset is on an outside line call, the received data is an on-hook code. Check whether it exists (step 102). If it is an on-hook code, the corresponding outside line lamp provided in the keyboard 46 of the handset is turned off (step 103), and the outside line is opened (step 103).
104), and registers in the state memory that it is being hooked (step 105). Thereafter, the footing timer is started (step 106). This hooking timer is provided using a predetermined area of the RAM 16, and is activated by setting a flag in the same predetermined area of the RAM 16.
Next, the timing operation will be explained.

FIG. 3 shows a timer processing program that is executed at fixed intervals as timer interrupt processing. , and performs the timing processing (step 202). Specifically, the contents of the timer provided in the RAM 16 are incremented by "1". As a result, when the content reaches a predetermined value, that is, when the time-up output is obtained (step
203), the processor unit 14 turns off the corresponding outside line lamps of all slave units (step 204), and registers in the status memory that the outside line and slave unit are in an idle state (step 205). In this embodiment, the timer time of this hooking timer is set to 1.5 seconds. Other timers other than the hooking timer are processed in the same way (step 206). It goes without saying that an independent timer circuit may be used instead of such a so-called soft timer.

In FIG. 2, if the received data is not an on-hook code but another code, for example a button code corresponding to a key operation, other processing is performed according to that code (step
107).

On the other hand, if the received data is an off-hook code (step 101), but not during an outside line call (step 101), and if the received data is an off-hook code (step
109), turns on the corresponding outside line lamp of the handset (step 110), reacquires the outside line (step 111), and registers the fact that an outside line call is in progress in the status memory (step 112).

If the caller is not on an outside line call or is not in the process of hooking up (step 108), other processing is performed depending on the state (step 113).

Therefore, when an on-hook is performed on a certain key telephone, the corresponding outside line lamp remains lit until the hooking timer times up for other key telephones; , the corresponding outside line lamp will turn off when the operation is performed.
This allows the user to immediately confirm that the outside line is open.

As described above, the transition to the operational data setting mode is performed by a specific operation from a specific slave device determined according to the accommodation position,
Although an example in which operational data is set has been described, a dedicated input port may be provided for the processor unit 14, and operational data may be input from this input port. In this case, for example, a connector is provided to be connected to the dedicated port, and the slave unit with the display is reconnected to this connector, and input is performed from there.

Further, although the above-described embodiment is a system that accommodates multiple lines and uses a star connection between the main device and slave devices, the present invention can be similarly applied regardless of the number of lines and connection method. .

[Effect of idea]

As explained above, according to the present invention, the on-hook information during an outside line call is used to display the release of the corresponding outside line on the key telephone, and the off-hook information is displayed while the hooking timer activated by the on-hook information is operating. By providing the above-mentioned button telephone with a display control means that displays the capture of the relevant outside line, when the phone goes on-hook due to the end of a call, the display of the outside line release will be delayed, and the user will no longer feel anxious. .
