Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a call display method for a telephone connected to a telephone device to which a plurality of outside lines are connected.

[Prior Art] In a conventional telephone connected to a telephone device to which multiple outside lines are connected, if the number of outside lines stored in the telephone device is greater than the number of outside line indicators of the connected telephone, the connection to the outside line is The outgoing call display or the called display from an outside line can be displayed as long as it is from an outside line within the range where the outside line can be displayed. For example, if the outside line has a called display, select that outside line. There is no inconvenience in answering calls from outside lines, but if there are calls from outside lines that exceed the outside line display capacity of the telephone, it will not be possible to answer.

In such a case, you cannot answer the call unless you check the called outside line display on the telephone equipped with an outside line display for the outside line stored in the telephone device, and in reality, you cannot answer the call from such a telephone. I was unable to respond.

In other words, in order to respond to incoming calls from outside lines that exceed the display capacity using such a telephone, it is necessary to respond to calls from outside lines that exceed the display capacity by using a telephone that is equipped with more outside line displays than the number of stored outside lines.
The called outside line had to be answered by identifying the called outside line by looking at the outside line display and informing the telephone operator of the same.

[Problems to be Solved by the Invention] As described above, a connected telephone always requires a larger number of outside line displays than the number of accommodated outside lines. The number of displays, corresponding selection keys, etc. had to be increased. As a result, the entire exterior of the phone had to be rebuilt and replaced.

In addition, it is very inconvenient to use a telephone used in a system with a small number of outside lines to be used in a system with many outside lines. In other words, the operator had to follow the instructions given by the operator of the other telephone.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above-mentioned problems, and as a means for solving the above-mentioned problems, an embodiment according to the present invention has the following configuration. .

That is, called detection means detects incoming calls from a plurality of outside lines, at least one display means displays call detection by the called detection means, and the display means has a distinguishable display for each outside line. and a display control means for performing display in the form of a display.

Moreover, the configuration is further provided with a key associated with the display means.

[Function] With the above configuration, by displaying and identifying the called outside line among many stored outside lines with a small display capacity of the display means, the display form can be simply changed as the number of stored outside lines increases. One of the stored outside lines can be specified by .

In addition, by providing a key, the display format of the display means can be changed in chronological order, and by inputting this corresponding key in synchronization with the display timing of the format corresponding to the called external line, multiple external lines can be displayed on the key. A desired called external line can be specifically selected even if it is assigned.

[Example] Hereinafter, an example according to the present invention will be described in detail with reference to the drawings.

A display 31 indicates incoming calls from outside lines 4 to 8.

Further, 32 is a call request key when calling another telephone etc. from the telephone, and 33 is a telephone number key for inputting a telephone number, which is composed of a numeric keypad, a "straw" key, and a "#" key. has been done.

The call detection and response processing for the call in this embodiment having the above configuration will be explained below with reference to the flowchart of FIG.

When the telephone device of this embodiment is powered on, the control unit 11
In step S1, an initialization process is executed to initialize the telephone device 10, and a process for bringing all connected telephones into an initial state is executed. Note that the initialization of the telephone is performed every time the power is turned on thereafter and a telephone is newly connected. Then, it is held in an idle state until an activation factor occurs in steps S2 and S3. Here, if there is an activation factor, step 84 is performed from step S3.
Proceed to the following process to check the activation factor.

There are various activation factors, but in the telephone device 10, they can be roughly divided into those caused by the telephone and those caused by the stored outside line. On the other hand, on the telephone side, the operator inputs keys on the telephone or requests a call by off-hooking the handset 21, receives a control signal from the telephone device 10, and the like. These control signals include a paging signal accompanying detection of a called call, a transfer request signal from another extension telephone, and the like.

First, in step S4, it is checked whether the call request is from a telephone. When a call request is made by inputting the call request key 32 of the telephone or by off-hooking the handset 21, a notification to that effect is sent from the telephone to the extension interface 14 of the telephone device 10 via the connected extension, and is recognized by the control unit 11. . Therefore, the process proceeds from step S4 to step S5, where it is checked by the trunk circuit 12 or the like whether or not each of the outside lines A1 to 88 has an empty outside line. If there is an over-the-air line, the process proceeds to step S6, in which the over-the-air line is captured and a dial tone is output to the call requesting telephone, and a call-ready display control signal is output to notify that the call is possible, and the display of the telephone shows "". ``Allow to dial'' etc. is displayed, and ``Allow to make a call'' is displayed. The operator of the telephone receiving these notifications knows that a call can be made, and then inputs the telephone number of the destination using the telephone number key 33. This phone number key 33
The telephone number information corresponding to the input is sent to the telephone device 10, converted into a corresponding telephone number signal, and sent out from the outside line. Therefore, a switching device such as a public telephone line connected to the outside line analyzes this telephone number signal, identifies the desired telephone, and sends a called signal (ringing signal) to the specified desired destination. . When the other party responds to this call and takes off the hook of the handset 21, a communication path is established between the two power packers as shown in step S8, and a conversation between the two power packers becomes possible in step S9. After that, the call ends in step SIO, the handset of either telephone is on-hook, and the call path is opened. When the 11th call path is released, the call path with the extension phone is also released in step Sll. to return to the initial state, and return to step S2 to prepare for the occurrence of the next activation factor.

On the other hand, if there is no outside line in step S5, step S15
Step S16 outputs a busy tone and an outside line busy control signal to the telephone to notify that it is impossible to make a call, and the display of the telephone changes to ``Outside line busy'', and this display remains until the next activation factor occurs in step S16. continue. As the next activation factor, there are a case where the stored vacant line becomes empty, a case where a timer is started for a predetermined period and the timer times out, and the like. In these cases, in step S17, the ``outside line'' and ``G'' displays on the display of the telephone are erased, and the process returns to step S2.

Next, if the activation factor in step S3 is not a call request from the telephone, the process advances from step S4 to step S20, where it is checked whether the called detection section 15 detects a called signal from an outside line. If the call is not detected, the process proceeds to step S25, and it is checked whether or not there is another activation factor. If it is not another activation factor, the process returns to step S2. If the activation is caused by another factor, the process proceeds to step S26. After performing predetermined operations and processing corresponding to the cause, the process returns to step S2.

In this embodiment, there are control for forming communication channels between extensions, telephone transfer processing, etc., but since these controls are well known, their explanation will be omitted.

On the other hand, if a called signal from an outside line is detected in step S20, the process advances from step S20 to step S30;
The telephone device 10 outputs a display control signal to display any one of the displays 28 to 31 of the connected telephone in a display time pattern corresponding to the called detection line. The telephone that receives this display control signal controls the displays 28 to 31 of the telephone according to the control signal.

In this embodiment, two outside lines are assigned to one display, and a display time pattern is used to distinguish which outside line the call is coming from or whether a call is received on both outside lines at the same time. This display control signal (
An example of the display time pattern is shown in FIG.

41 in the figure is a display pattern corresponding to an outside line with a small number, and for example, on the display 28, it shows the display timing of outside line 1 (At). 42 is a display pattern corresponding to an outside line with a large outside line number, and for example, the display 28 shows the display timing of outside line 5 (A5). Therefore, when a call is detected on both outside lines, the display timing shown by reference numeral 43 is reached.

Therefore, the operator who sees these displays should proceed to step S.
At step S31, it is determined whether or not to answer using the own telephone, and if the answer is not made using the own telephone, the process returns to step S2. When responding, in step S32, the display pattern on the display is checked to see if there are calls from a plurality of lines, that is, two lines, for the outside line selection keys 24 to 27 corresponding to the display.

If multiple calls are not detected, the process advances to step S33;
Press and input the selection key of the outside line you wish to answer. Then, in step S35, this input information is sent to the telephone device 1o, and the control section 11 connects the answering telephone and the called line to form a communication path, and proceeds to step S9 to conduct a telephone conversation.

If it is determined in step S32 that there are multiple called lines, the process advances to step S34, and while checking the display pattern of the corresponding display, select the outside line in a state where the display pattern corresponding to the outside line to which you are attempting to answer is being displayed. Press the key to input. For example, if you input the outside line selection key at timing "A", the external line with the larger number will be selected, and if you input the external line selection key at timing "B", the external line with the smaller number will be selected, and so on. A communication path is formed between the outside line and the answering telephone. Then, the process advances to step S35.

As described above, according to this embodiment, a plurality of stored outside lines can be assigned to one display and selection key, and a called display can be performed using a display pattern that allows the outside lines assigned to time sharing to be distinguished. It is possible to specify the outside line, etc. where a called call is detected. Further, by making a key input in accordance with the display timing of a display pattern specific to an outside line, it is possible to recognize that the key input is for an outside line corresponding to the pattern being displayed.

In this way, according to this embodiment, even if the number of outside lines accommodated in the telephone device 10 increases, the existing telephone can be used as is without having to replace the telephone each time.

The above description has been made for outside line 1 and outside line 5 (external line 115), but outside line 2/6.3/7.4/8 may be similarly displayed using the same pattern.

[Other Embodiments] In addition, the display pattern for specifying the outside line is not limited to the timing shown in FIG. 4, and other embodiments include display timings (display patterns) such as those shown at 51 to 53 in FIG. You may also do so.

In this case, if only one of the external lines is being called, a display pattern specific to the external line to be called is continuously displayed (51, 52), and when attempting to display multiple external lines at the same time, Alternate display as shown in 53 may be used.

Another possibility is to arbitrarily change the display time pattern.

Furthermore, as another embodiment, instead of the identification based on the display time pattern, the identification may be performed by changing the display color. In this case, a configuration may be provided in advance that includes a display device capable of displaying multiple colors (for example, a display device composed of a plurality of LEDs, etc.).

Further, the outside line display is not limited to when a call is detected, but by controlling the outside line to be displayed in a different display pattern when the outside line is used by a telephone or the like, it is also possible to know the availability of the outside line.

Furthermore, the number that can be displayed on one display is not limited to two outside lines, and more outside lines may be associated with each other and a unique display pattern may be assigned to each outside line.

[Effects of the Invention] As explained above, according to the present invention, it is possible to specify the display for one of many outside lines by only providing a limited number of outside line displays and keys, and it is possible to specify the display for one of many outside lines, thereby reducing the number of outside lines accommodated. This eliminates the need to change the connected telephone, and also reduces the number of keys and displays on the telephone.

By using the present invention in this way, it is possible to connect a telephone with a small number of outside line display means and keys without being restricted by the number of stored outside lines, and it is also possible to use phones of the same standard in various telephone systems. , there is also a big advantage in cost reduction.
