Abstract

PURPOSE:To enhance the operability of a caller operator by applying a call by automatic dialing to other line automatically after a caller terminal equipment is restored automatically to the standby state when a 1st line making automatic dialing is busy. CONSTITUTION:If the line of the first priority is busy, a busy tone is sent from an exchange to a caller terminal equipment. Suppose that number of lines of communication parties registered in a RAM 8 is 3, since the priority of n=2 is obtained, the telephone line of the 2nd priority line is read this time from an area of the RAM 8 corresponding to a subscriber selection key 72. Thus, the call by the automatic dialing to the line of a 2nd priority is applied. When the line is in the standby state, a call is given from the exchange to an opposite terminal equipment and when the subscriber of opposite terminal equipment replies the call, the talking state is transited.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an improvement in a communication terminal device having an automatic dialing function.

(Prior Art) In recent years, many communication terminal devices such as telephone devices and facsimile devices are equipped with an automatic dial dialing surface. This automatic dialing function, for example, stores the telephone number of the desired communication partner in advance in the dialing information memory in association with the registered number, and is activated when any registered number is input using the dial key or subscriber selection key. A telephone number to be received is read from the dial information memory, and a dial signal consisting of a dial pulse or a DTMF signal is generated in accordance with the telephone number and sent to the line. Therefore, when using a device equipped with this type of call function, the subscriber can register the telephone number of the desired communication partner in advance in the dialing information memory, and when making a call, the subscriber can register the telephone number of the desired communication party in advance with a single touch or a small number of registered numbers. It is very convenient because you can make a call with a simple operation just by inputting the following.

On the other hand, recently, there are many subscribers who own multiple lines depending on the communication partner, such as large businesses or offices, and when making a call to such a communication partner, the subscriber is in a standby state. It is possible to select a line that is marked as .

However, the conventional communication terminal device equipped with the automatic dialing function stores the telephone number of one line for each communication partner in the dialing information memory, and therefore has multiple lines as described above. Even when making a call to a communication partner, the call can only be made by automatic dialing to one of the lines that the user owns, the telephone number of which is stored in the dial information memory.

Therefore, if the line from which the auto-dial call was made is in use, the caller must take the handset off-hook to temporarily release the line, and then manually enter the phone number of another line. you must make a call,
Making a call was extremely troublesome. Additionally, in order to be able to make automatic dialing calls to any line owned by the communication partner, it may be possible to store each line's telephone number in association with a different subscriber selection key. In this case, since the number of subscriber selection keys is limited, the number of communication partners that can be automatically dialed and registered is reduced, which is extremely undesirable.

(Problems to be Solved by the Invention) As described above, with the conventional device, even if a communication party owns multiple lines, it is only possible to make a call using automatic dialing to one of the lines. However, it is difficult to make calls because you have to manually make calls to other lines.Also, if you can make automatic dial calls to all lines owned by the communication partner, it will be difficult to register automatic dial calls. However, this invention has the problem that the number of communication partners that can be communicated with is reduced, which is inconvenient. To provide a communication terminal device that enables automatic dialing to be made to each of a plurality of owned lines, thereby improving the operability of a calling operator, and making it possible to make calls to many communication parties by automatic dialing. That is.

[Structure of the Invention] Means for Solving the Problems) As shown in FIG. Information memory A, line status determining means B for determining whether or not the line of the called side is in communication based on a signal arriving from the communication network after sending out a dial signal, first dial sending means C, and second dial sending means C. When a call request to a communication party is input, the first dial sending means C outputs the dial number of the first line among the plurality of corresponding dial number information from the dial information memory. The information is selectively read and a dial signal corresponding to this dial number information is sent to the communication network, and after the first dial sending means C sends out the dial signal, the line status determining means B determines whether the first line is If it is determined that the communication is in progress, the second dial sending means returns to the standby state and then retrieves the second dial number information from among the plurality of dial number information corresponding to the communication partner from the dial information memory A. The dial number information is selectively read out and a dial signal corresponding to the dial number information is sent to the communication network.

(Effect) As a result, if the first line that made the auto-dial call was in use, the calling terminal automatically returns to the standby state and then automatically dials the other line. Since a call is to be made, the calling operator stores in advance a plurality of dial number information belonging to the communication partner, and then operates, for example, one subscriber selection key corresponding to the communication partner. By simply doing this, not only will a call be made to the first line, but also a call will be made to the second line if the first line is in use. The operations involved are significantly simplified. In addition, since multiple dial number information owned by a communication partner is stored in association with a registration number preset for each communication partner, automatic dialing can be registered for the number of communication partners corresponding to the number of registration numbers. can improve service quality.

(Embodiment) FIG. 2 shows the configuration of a telephone device which is a communication terminal device in an embodiment of the present invention.

This device is broadly divided into a telephone section and an automatic dialing section, which are alternatively connected to a subscriber sii of an exchange (not shown) by a switching relay contact 2. First, the telephone unit includes a telephone circuit 3, a transmitter 41, and a receiver 4.
2 and a hook switch 5 that is linked to the hook operation of the handset 4.

On the other hand, the automatic dialing device section is, for example, a micro combination 1-
The control circuit 6 has a control circuit 6 consisting of an electric current. This control circuit 6 is composed of a main control section (CG) 61, a ROM 62 that stores its operating program, and an input section 63 and an output section 64 consisting of an I10 board. Operation signals of the provided dial key 71, subscriber selection key 72, redial key 73, Bose key 74, hooking key 75, registration key 76, and call switch 77 are input. Note that 78 is a hook contact that generates a hook signal in conjunction with the on/off operation of the hook switch 5 and inputs it to the control section 6.

The control circuit 6 also includes an RA as a dial information memory.
M8 is attached. For example, as shown in FIG. 3, this RAM 8 stores the telephone numbers of a plurality of lines owned by each communication partner in areas corresponding to each key of the subscriber selection key 72. . Note that 81 is a backup power source for the RAM 8 in case of a power outage.

On the other hand, the output section 64 of the control circuit 6 outputs drive control signals to the DTMF signal generation circuit 9, relay drive circuit 10, and display 18, respectively.

First of all, the DTMF signal generation circuit 9 generates a DTMF (D
ual Tone MultiFreQuenCV
) signal, and this DTMF signal is transmitted through the line transformer 12, switching relay contact 2 and dial contact 11.
are sent to the subscriber line 1 via the respective channels. Further, the relay drive circuit 10 operates the switching relay contact 2 and the dial contact 11 for transmitting dial pulses in accordance with the drive control signal from the Ill111 circuit 6. Further, the display 18 lights up in response to the dial signal sending operation, thereby notifying the user that the dial signal is being sent. Further, a signal detector 13 is connected to the subscriber line 1. This signal detector 13 detects the dial tone, busy tone, and
It detects a signal representing the exchange connection state, such as a ring bank tone, and outputs the detection signal to the control section 6.

14 is a loudspeaker receiving circuit used when making an on-hook call, and includes an amplifier 15, a speaker 16, and a mute circuit 1.
It consists of 7.

By the way, the control circuit 6 includes dial number registration control means 65, first dial transmission control means 66, and second dial transmission control means 67 as shown in FIG. 4 as control means related to the calling operation. ing. First, with the registration mode designated by the operation of the registration key 76, the dial information registration control means 65 corresponds to an arbitrary key of the subscriber selection key 72 to input information for each communication network for a desired communication partner. When telephone numbers are input, these telephone numbers are prioritized and stored in storage areas corresponding to the subscriber selection keys of the RAM 8, respectively. Note that this priority order is set, for example, in the order in which telephone numbers are input. The first dial sending control means 66 also controls the subscriber selection key 7.
When the 2 or redial key 73 is operated, the acquisition control of the subscriber line 1 is performed, and the priority number 1 is selected from the storage area of the RAM 8 corresponding to the subscriber selection key 72.
Reads the phone number of the current line, and sends a dial pulse or DTMF signal corresponding to this phone number to the dial contact 11.
Alternatively, the DTMF signal is generated from the DTMF signal generation circuit 9 and sent to the exchange via the subscriber line 1. Roughly speaking, the second dial sending control means 67 determines whether or not a busy tone detection signal is output from the signal detector 13 after the first dial sending controlling means 66 sends out the dial signal, and detects the busy tone. When the detection signal is output, the subscriber line 1 is temporarily released by switching the switching relay contact 2, and after a predetermined pause period, the same storage area corresponding to the subscriber selection key in the RAM 8 is opened. The telephone number of the line with the second highest priority is read out from the telephone number, a dial pulse or DTMF signal corresponding to this telephone number is generated, and the signal is sent to the exchange via the subscriber line 1. If the line with the second priority is originally G, the second dial transmission control means 67 reads the telephone number of the line with the third priority and performs re-calling control. In other words, R until a waiting line is found.
Each telephone number stored in AM8 is selected according to the priority order, and automatic dialing control is performed for each telephone number.

Next, the operation of the device configured as described above is controlled by a control circuit 6.
This will be explained according to the control procedure. The following explanation assumes that the RAM 8 already stores the telephone numbers of each line owned by a desired communication partner in association with each subscriber selection key 72, as shown in FIG. 3, for example.

In the standby state, the control circuit 6 monitors the operation of the registration key 76, monitors the occurrence of incoming calls, and monitors the occurrence of outgoing calls in steps 5a, 5b, and 5c, respectively, as shown in FIG. In this state, if the subscriber goes off-hook by picking up the handset 4 or pressing the call button 77, the control circuit 6 detects this in step 5C and proceeds to step 5d, where the switching relay contact 2 is first turned on. By switching from the telephone unit side to the automatic dialing unit side, the line (subscriber line 1) is acquired using the line transformer 12. Note that if the user goes off-hook by picking up the handset 4, the line is captured when the hook switch 5 is turned on.

In this state, when the calling operator confirms the arrival of the dial tone DT and inputs the telephone number of the communication partner by operating the dial key 71, the control unit 6 detects this operation and then proceeds to step 5e. Here, it is determined whether the dialing operation is manual or automatic. In this case, since the call is made manually using the dial key 71, the control circuit 6 moves to step 5f, where it inputs the dial key code one digit at a time, and then, in step 5g, dial pulse or DTMF according to the dial key code. A signal is generated from the dial contact 11 or the DTMF signal generating circuit 9 and sent to the subscriber [11]. Then, in step 5h, it is determined whether all digits of the dial signal have been sent, and when the dial signal is finished, in step 51 and step 5j, the response of the called terminal is monitored and the calling party abandons the call, respectively. If the calling side answers, the process moves to step 6C in FIG. 6, where call control is carried out, and when the end of the call is monitored in step 6d and the end of the call is detected, the line is released in step 6e and the process returns to the standby state. On the other hand, if the caller abandons the call, the control circuit 6
The process moves to step 5k, where the line is released and the process returns to the standby state.

On the other hand, if the calling operator operates any subscriber selection key 72 after confirming the dial tone, the control unit 6 determines that the call is automatic in step 5e, and in step 5
Step 5n, enter the key code of the subscriber selection key 72, and set the line priority n to 1 in step 5n.
Set to . Then, in step 50, the telephone number of the line with the first priority is read out one digit at a time from the area corresponding to the key code of the subscriber selection key 72 in the RAM 8, and in step 5p, a dial pulse or DT corresponding to this telephone number is read out.
An MF signal is generated and sent to the subscriber line 1, and in step 5q, the display 18 is turned on to notify the calling operator that a call is being made.

When the transmission of the dial signal for all digits is completed, the end of the transmission of the dial signal is detected in step 5r, and the process moves to step 6a and step 6b in FIG. monitoring. Now, if the line with the highest priority on the called side is in a standby state and the communication partner is called, and the subscriber of the communication partner answers this call, the control circuit 6 shifts to call control in step 6C. After that, it will be possible to make calls between the two communication terminals.

On the other hand, if the line with the first priority is busy, the calling terminal receives a busy tone BT from the exchange.
will be sent. Then, the control section 6 detects the arrival of this busy tone BT from the detection signal of the signal detector 13, moves to step 6f, and first releases the line here. Then, in step 6g, after confirming that the predetermined time required for the recovery operation of the exchange has elapsed, step 6hrfi priority order n is incremented and set to n+1, and then, in step 61, priority order n is registered in RAM 8. Determine whether the number of lines has been exceeded. If the number of lines of the communication partner registered in the RAM 8 is 3, the priority order is n-2, so the process returns to step 50 in FIG. Next, read out the telephone number of the line with the second priority. Then, each time one digit of the telephone number is read out, a dial pulse or DTMF signal corresponding to this telephone number is sent to the subscriber line 1 in step 5p, and a call is being displayed in step 5q. In this way, a call is made by automatic dialing to the line with the second priority. If this line is in a standby state, a call is made from the exchange to the other party's terminal, and if the subscriber of the other party's terminal responds to this call, the line shifts to a talking state.

Similarly, if the calling line is busy, the priority n is lowered by 1 and the phone number of that line is selected.
The amount of dial signals sent is controlled according to this telephone number. Also, if the value of priority n exceeds the number of lines registered in the RAM 8, for example, if three lines are registered and the line with the third priority is also busy, step 6
1 to step 5n, where the priority order n is reset to 1, whereby the automatic dialing operation is repeated in order from the line with the first priority order.

As described above, in this embodiment, when trying to make a call using automatic dialing to a communication partner who owns multiple lines, if the line with the first priority is busy, priority is automatically given. Since the lines from the second place onwards are selected in order and the automatic dialing is performed, the calling operator can pre-store in RAM 8 the telephone numbers of the lines owned by the desired communication partner, and then By simply operating the subscriber selection key 72, automatic dialing to each line can be made selectively and sequentially. Therefore, the operability of the calling operator when making a call has been greatly improved, and the occurrence of input errors has been reduced compared to conventional devices in which the telephone number had to be entered manually each time. It becomes possible to make more accurate calls. In addition, since the storage area corresponding to each subscriber selection key 72 of the RAM 8 stores the telephone numbers of a plurality of lines owned by each communication partner, only the number of lines corresponding to the number of subscriber selection keys 72 can be communicated. It is possible to register parties by automatic dialing, thereby making it possible to make calls to a large number of communication parties by automatic dialing.

Note that the present invention is not limited to the above embodiments. For example, in the above embodiment, if all the lines owned by the communication partner are busy, the call is made repeatedly in order of priority, but when all the lines are determined to be busy, the call is made again. The call operation may be stopped, or after a certain period of time, an automatic call may be made again from the line with the highest priority. In addition, a display device such as a liquid crystal display device capable of displaying messages may be provided, and the name of the communication party being called and the line base may be displayed on this display device, and the results of automatic calling for each line may be displayed on this display device. may be stored as a history and read out and displayed according to instructions from the calling operator. In addition, the number of phone numbers of the line to be registered in the RAM, the configuration and storage format of the dial information memory, the configuration of the line status determination means, the control contents and control procedure of the first and second dial sending means, the type of communication terminal equipment (
A facsimile machine, etc.) can be modified in various ways without departing from the gist of the present invention.
