Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a communication device, in particular a system for communicating
The present invention relates to a communication device that accommodates several communication lines and performs communication using a plurality of voice terminals and communication devices of a predetermined method.

[Prior Art] In recent years, there have been an increasing number of cases in which not only telephones but also facsimile machines, data communication devices, etc. are connected to telephone lines. When using a communication device other than a voice terminal, such as a facsimile machine or a data communication device, the system is almost always configured so that both voice communication and predetermined communication operations by one communication device can be performed.

[Problems to be Solved by the Invention] In order to enable both voice communication and communication operation, several methods can be considered. Set up a dedicated line,
This method calls each of them using a different phone number.

In this method, the communication device is often connected together with the telephone, so that according to the manual procedure it is possible to both make and receive calls, but only if the communication device is set to automatic reception. I was unable to receive calls for calls.

In addition, as a method for connecting 11 communication devices, there is a system that uses a representative number.As is well known, when the representative number is in use, communication is performed using a line corresponding to another number. The following two methods can be considered for connecting a communication device to such a representative number system.

First, each time a call arrives, we detect whether the caller is trying to make a call by detecting the voice signal from the caller.
This is a method of providing a line control device that determines whether communication is to be performed and selects and connects an appropriate terminal device.

This method has the advantage of allowing both voice communication and communication using a predetermined method to be performed using any number, but has the problem that the cost of the system is extremely high because it requires a voice recognition device and the like. Furthermore, there is a problem in that if all the connected communication devices are in use, even if the calling party wishes to communicate, it is not possible to carry out communication operations using a predetermined method.

In addition, in a communication system that accommodates multiple lines under a representative number, a communication device is set to a specific telephone number, and when a call is received directly to that number, communication is performed instead of voice communication. Conceivable. In this system, when a call is received at a representative telephone number and a line other than the number to which one communication device is set is in use, connection is made to the line to which the communication device is connected. In such a case, even though the caller wishes to make a call, it is not possible to make a call.

In the case of facsimile machines and the like, even if a communication device is selected, a method such as telephone reservation is often provided so that a call can be made, but such control requires complicated operations.

[Means for Solving the Problems] In order to solve the above problems, the present invention accommodates a plurality of communication lines under a first telephone number and at least one second telephone number different from this, In the communication device, the second
If there is an incoming call to a telephone number, the communication means will perform a communication operation, and if there is an incoming call to a telephone number other than the second telephone number, and only the line corresponding to the second telephone number is free. , a configuration is adopted in which voice communication is performed using the voice terminal.

[Function] According to the above configuration, voice communication is always performed except when the second telephone number is directly specified, so a communication method not desired by the operator on the calling side is selected. there is no problem.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 shows the configuration of a communication system employing the present invention. Here, we consider a representative telephone number system. As shown in the figure, ten lines are accommodated, numbered 21 to 30. Telephone numbers A-J correspond to each of these, respectively.

As terminal devices, 24 telephones and two facsimile machines are considered. In Figure 1, telephones are numbered 4 from 6 to 9.
Only one telephone set is shown, and the illustration of the 21 telephones between 7 and 8 is omitted. The facsimile machine is code 1
4.16.

The one designated by the reference numeral 2 in FIG. 1 is an extension switch that selects one line 21-30. Further, when there is an incoming call, a signal level "1" is output to the signal line 2a. Further, a signal indicating whether the selection signal from the outside line exchange corresponds to the representative telephone number with a signal level of "0" or "1" is output to the signal line 2b. Signals on the signal lines 2a and 2b are input to a control circuit 18 composed of a microprocessor or the like.

Lines 21 to 30 are connected to either telephones 6 to 14 or facsimile machines 14 and 16 by line switching circuit 4 as required.

Voice lines 6a-9a for telephones a6-9 are telephone numbers A
-H is selected. In addition, the communication lines 14a and 16a for the facsimile machines 14 and 16 are respectively provided by telephone numbers and J! 1 Selected 0 line switching circuit 1
The line connection operation of 8a is performed by the control circuit 18 via the signal line 18.
controlled via a. Further, the line switching circuit 4 inputs the line number in use to the control circuit 18 via the signal line 4a. The control circuit 18 selects a connectable terminal device based on the data regarding the line number in use.

Telephones 6-9 have signal lines 6b-9b and signal lines 18b-
It is connected to the control circuit 18 by 18e. signal line 6
9b to 9b detect the hook state of the telephones 6 to 9, and the signal level is "0" in the on-hook state and rlJ in the off-hook state. Further, the signal lines 18b to 18e each ring the bell of each telephone, and a signal level of "1" causes the bell of each telephone to generate a ringing tone.

On the other hand, the facsimile devices 14 and 16 have signal lines 14b and 1
It is connected to the control circuit 18 through 6b, 18f, and 18g. Signal lines 14b and 16b indicate whether or not each facsimile machine is in use; the signal level becomes "1" when the facsimile machine is in use, and signal lines 18f and 18g activate each facsimile machine. Each facsimile machine is activated by the signal level rlJ of these signal lines.

In the above configuration, if the calling party directly selects the representative telephone number set for any of telephone numbers A to H, or directly selects one of these telephone numbers, use one of telephones 6 to 9. When telephone numbers I or J are selected, the facsimile machines 14 and 16 respectively perform communication operations.

In addition, when a call is received at the representative number and all lines other than the line 29.30 corresponding to the telephone number and J are in use, this line is used, but in this embodiment, the facsimile machine 14
．． With this configuration, the line connection is made using an available telephone among the 24 telephones 6 to 9 without connecting to the fax machine 16, even though the calling party wishes to make a call. FIG. 2 shows in detail zero or more procedures that can prevent line connections from being made.

FIG. 2 shows an outline of the control program of the control circuit 18, and the illustrated program is stored in the ROM 18a.

In step S22 of FIG. 2, the control circuit 18 first checks the state of the signal line 2a, and determines whether or not the exchange 2 has detected an incoming call.If there is an incoming call, step S22 is performed.
24, the state of the signal line 2b is checked to determine whether there is an incoming call to the 1 representative number. If the incoming call is to the 0 representative number, go to step S42; otherwise, step S32.
Move on to 6.

In step S42, it is determined whether any of the telephone lines 21-28 corresponding to telephone numbers A-H is not in use. If there is a free line, in step S44 the lines with the lowest telephone number are selected and the lines are connected.

In step 346, it is determined whether the line 29 corresponding to the telephone number is in use. If it is in use, the process moves to step 550, and if it is not in use, the process moves to step 348. In step S48゜550, each phone number 1
．． Lines 2 to 30 corresponding to J are selected and connected.

On the other hand, in step S26, the line 2 corresponding to the telephone number
9 is received. If step 526 is affirmed, the process moves to step S28, and if negative, the process moves to step S34.

In step S34, as in step 326, the phone number J
It is determined whether the call is received on the line 30 corresponding to . If this step is affirmed, the process moves to step 336, and if this step is negative, the process moves to step 352.

In step 528, the line switching circuit 4 connects the line 29 to the signal line 14a and selects the facsimile machine 14. Further, in step 336, the line 35 is connected to the signal line 16a.
and select the facsimile device 16.

In step S30.38, each facsimile device 59
14. Start 16 respectively.

Step S32. In S40, an image communication operation is performed by the facsimile devices 14 to 16.

In step S52, the status of the signal lines 6b to 9b is checked, unused telephones are detected, and the bell of one of the unused telephones is ringed.

Signal lines 18b to 18e are used to ring the bell.

In step S54, an off-hook state of the telephone that rang the bell in step S52 is detected via the signal lines 7b to 9b, and a line connection is made to this telephone using the line switching circuit 4. At this time, the line switching circuit 4 18a. In step 556, a telephone call operation is performed using the connected telephone.

According to the above configuration, 1. If telephone number J is selected, facsimile communication is performed using facsimile device 14.16. If either the 0 representative number or telephone numbers A-H is specified, the telephone is selected and the phone is off-hook. Voice communication is performed by the telephone that was used.

In addition, if the representative number is selected but lines 21 to 28 set for voice communication are in use, line 29 is selected.
to 30 are used, but the facsimile machines 14 and 16 are not used, and one of the 24 telephones 6 to 9 is used for voice communication.

Therefore, unlike in the conventional representative number system, there is no possibility that a call will be received by the communication device even though the calling party wishes to make a call.

Although a facsimile device has been exemplified as a communication device in the above, a similar configuration can be implemented even when a data communication device other than a facsimile device is used.

In the above embodiment, the representative number system is not used for the facsimile machine corresponding to telephone number J. In other words, if the line corresponding to telephone number I is in use, the line corresponding to telephone number J is used. It is also possible to control the use of the facsimile machine 16.

[Effect of the invention] As is clear from the above description, according to the present invention, the first
A plurality of communication lines are accommodated under a telephone number and at least one second telephone number different from this telephone number, and communication processing is performed by a communication means that performs voice communication by a plurality of voice terminals and non-voice communication of a predetermined method. When a call is received at the second telephone number, the communication device performs a communication operation, and if a call is received at a telephone number other than the second telephone number, the communication device responds to the second telephone number. If only the line to which the call is made is available, voice communication is performed using the voice terminal, so a communication method different from that desired by the calling party will not be selected, and the appropriate terminal device will always be connected. This has the excellent effect of allowing you to choose.
