The present invention relates to an improvement of a communication terminal device equipped with an automatic dial transmission function.

Recently, many communication terminal devices such as telephone apparatuses and facsimile apparatuses are equipped with an automatic dial call function. That is, the automatic dial call function is a dial key or subscriber that corresponds to, for example, a telephone number of a desired communication partner. When inputted by a selection key, a corresponding telephone number is read out from the dial information storage device, and a dial signal consisting of a dial pulse or a DTMF (Duel Tone Multi Frequency) signal corresponding to the telephone number is generated and transmitted to a line. will be.

Therefore, if a communication terminal device having this kind of calling function is used, the subscriber registers the desired communication partner's telephone number in the dial information storage device in advance, so that when a call is issued, a registration number of one touch or a small digit is issued. Since it is possible to send and receive calls with simpler operation, it is very convenient.

On the other hand, in recent years, a large number of subscribers own a plurality of lines by a communication partner, such as a large establishment or office, and when making outgoing calls to such a communication partner, select a line that is in a standby state. It is possible to make a call.

By the way, since a communication terminal device having a conventional automatic dial transmission function stores the telephone number of one line for one communication partner in the dial information storage device, the communication partner who owns a plurality of lines as described above is used. Even when making outgoing calls, outgoing outgoing calls based on automatic dialing can be made only for one line in which the telephone number of each owned line is stored in the dial information storage device.

Therefore, when this automatic dialing line is in communication, the call originating operator must open the line once the handset is off hooked, and then manually enter the telephone number of the other line to make the call. Manipulation was a remarkable hassle.

In addition, since automatic dialing is performed on any line owned by the communication partner, it is also considered that one telephone number of each line is stored in correspondence with a different subscriber selection key. Because of this limitation, the number of communication partners performing automatic dial transmission registration becomes small, which is not very desirable.

As described above, the conventional communication terminal apparatus can only make outgoing calls according to automatic dialing for one of the communication counterparts owning a plurality of lines, and do not make outgoing calls manually for the other lines. Since the call outgoing operability is bad because it has to be done, and the automatic dialing is also performed for the entire line owned by the communication partner, there is a problem that the number of the communication partners that can register the automatic dialing becomes small and becomes inconvenient.

Accordingly, the present invention has been invented to solve the above problems, without limiting the number of the communication partner that can be registered automatic dialing, and to automatically dial each of a plurality of lines owned by the communication partner, Accordingly, an object of the present invention is to provide a communication terminal device capable of increasing the operability of an outgoing call operator as well as making outgoing calls according to automatic dialing for many communication partners.

The communication terminal apparatus of the present invention for achieving the above object is a dial information storage device (A) which stores dial number information of a plurality of lines owned by the communication partner for each desired communication partner as shown in FIG. And line state determination means (B), first dial transmission means (C), and second dial transmission means for determining whether the called line is in communication from the signal arriving from the communication network after the dial signal is transmitted; (D), the first dial transmitting means (C) by the first dial transmitting means (C) when a request for outgoing call output to the communication counterpart is inputted; Selectively reads out the dial number information, not only transmits the dial signal corresponding to the dial number information to the communication network, but also transmits the dial signal by the first dial transmitting means (C); If it is determined later by the line state determining means (B) that the first line is in communication, the second dial transmitting means (D) returns to the standby state and then the dial information storage device (A) And selectively read out the second dial number information from among the plurality of dial number information corresponding to the communication partner, and transmit the dial signal corresponding to the dial number information to the communication network.

As a result, according to the present invention, when the first line that is automatically dialed is in communication, the terminal of the originating caller side automatically returns to the standby state, and then the caller is automatically issued to another line by automatic dialing. Therefore, the call originating operator stores in advance a plurality of pieces of number information owned by the communication partner, so that, for example, as long as one subscriber selection key corresponding to the communication partner is operated, not only the call origination is output on the first line. Since outgoing calls are automatically made to the second line when the first line is in communication, the operation related to outgoing calls is remarkably simplified. In addition, the plurality of dial number information owned by the communication partner is stored in correspondence with the registration number set in advance in the communication partner unit, and the communication partner can be automatically dialed and registered by the number corresponding to the number of registration numbers, thereby increasing the service. Will be.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 shows the configuration of a telephone apparatus which is a communication terminal apparatus according to an embodiment of the present invention. The telephone apparatus which is a communication terminal apparatus is largely divided into a telephone portion and an automatic dial apparatus portion, and these switch relay contacts ( 2) it is connected to the subscriber line 1 of the exchange which is not shown selectively. First, the telephone unit is composed of a call line 3, a handset 4 incorporating a handset 41 and a handset 42, and a hook switch 5 interlocked with a hook operation of the handset 4. .

On the other hand, the automatic dial unit includes a control circuit 6 composed of, for example, a one-chip microcomputer, which includes a main controller 61 and a ROM 62 and an I / O storing the operation program. It consists of an input unit 63 and an output unit 64 formed of ports, among which the input unit 63 includes a dial key 71, a subscriber selection key 72, a redial key 73, and one end disposed on an operation panel. Each operation signal of the stop key 74, the hooking key 75, the registration key 76 and the originating switch 77 is input. Reference numeral 78 denotes a hook contact input to the control circuit 6 for generating a hook signal in association with the on / off operation of the hook switch 5.

In addition, the control circuit 6 is provided with a RAM 8 as a dial information storage device, which is an area corresponding to each key of the subscriber selection key 72, for example, as shown in FIG. In addition, each communication partner stores telephone signals of a plurality of lines owned by the communication partner. Reference numeral 81 denotes a power white power supply to the RAM 8.

On the other hand, the drive control signal is output from the output unit 64 of the control circuit 6 to the DTMF signal generation circuit 9, the relay drive circuit 10 and the indicator 18, among which DTMF signal generation circuits. (9) generates a DTMF signal, which is sequentially sent to the subscriber line 1 via the line transformer 12, the switching relay contact point 2, and the dial contact point 11. In addition, the relay contact 2 and the dial contact 11 for dial pulse transmission are operated respectively. The indicator 18 is then turned on in accordance with the operation of sending the dial signal, so that the indicator 18 notifies the user that the dial signal is being sent.

In addition, a signal detector 13 is connected to the subscriber line 1, and the signal detector 13 maintains a switched connection state such as dial tone, busy tone and ring back tone coming from the exchange after the dial signal is transmitted. The detection signal is detected and the detection signal is output to the control circuit 6. Reference numeral 14 denotes an amplification hydration circuit used for on-hook transmission, and is composed of a heavy amplifier 15, a speaker 16, and a muting circuit 17.

By the way, as shown in FIG. 4, the control circuit 6 is a control means relating to an outgoing signal output operation, as shown in FIG. 4, a dial number control means 65, a first dial transmission control means 66, and a second dial transmission control means ( 67). First, the dial information registration control means 65 inputs a telephone number for each communication network to a desired communication partner corresponding to an arbitrary key of the subscriber selection key 72 in the state where the registration mode is designated according to the operation of the registration key 76. In this case, these telephone numbers are stored in the storage areas corresponding to the subscriber selection key 72 of the RAM 8, respectively, with priority.

Here, the priority is set in the order of input of the telephone number, for example.

Further, the first dial transmission control means 66 performs supplemental control of the subscriber line 1 when the subscriber selection key 72 or the redial key 73 is operated, and the subscriber selection key of the RAM 8 ( 72. The telephone number of the line with the highest priority is read out from the storage area corresponding to 72), and a dial pulse or DTMF signal corresponding to the telephone number is generated from the dial contact 11 or the DTMF signal generating circuit 9 and joined. It is sent out to the exchange via the charity (1).

Subsequently, the second dial transmission control means 67 determines whether or not a busy tone detection signal is output from the signal detector 13 after the dial signal is transmitted by the first dial transmission control means 66. When the detection signal of the busy tone is output from the signal detector 13, the subscriber line 1 is released once the switching relay contact point 2 is switched and the predetermined end stop period is retained. 8) Reads the telephone number of the line with the second priority from the same storage area corresponding to the subscriber selection key 72 of 8), generates a dial pulse or DTMF signal corresponding to the telephone number, and passes through the subscriber line 1. It will be sent to the exchange. The second dial transmission control means 67 reads out the telephone number of the line with the third priority and executes outgoing call control again when the line with the second priority is also busy. That is, a temporary telephone number stored in the RAM 8 is selected according to priority until the standby line is found, and then automatic dial transmission control is performed according to the telephone number.

Next, the operation of the communication terminal device configured as described above will be described in accordance with the control procedure of the control circuit 6.

First, it will be explained that the telephone number of each line owned by the desired communication counterpart is already stored in the RAM 8 in correspondence with each subscriber selection key 72, as shown in FIG.

In the standby state, the control circuit 6 monitors the operation of the registration key 76, the occurrence of incoming calls and the occurrence of outgoing calls, in steps 5a to 5c, respectively, as shown in FIG.

In this state, if the subscriber puts off the handset 4 or presses the outgoing switch 77, the control circuit 6 detects it in step 5c and then proceeds to step 5d, where the switching relay contact is made first. As (2) is switched to the telephone part side, the line transformer (12) is used to replenish the line (subscriber line 1). In addition, when the handset 4 is lifted off, the line is replenished when the hook switch 5 is turned on.

In this state, if the call originating operator who confirms the arrival of the dial tone DT enters the telephone number of the communication partner, for example by operating the dial key 71, the control circuit 6 detects the operation and then proceeds to step 5e. Thus, it is determined whether the dial transmission operation is manual or automatic.

In this case, since the manual call signal is issued by the dial key 71, the control circuit 6 is understood as step 5f, and the dial key code is input one by one, and the dial contact 11 or DTMF signal is continued in step 5g. It is generated from the generation circuit 9 and sent to the subscriber line 1.

Therefore, in step 5h, it is determined whether the dial signal has been transmitted by the whole digit, and if it has been completed, if the whole digit is finished, in step 5i and 5j, respectively, the response monitoring of the called terminal and the call out by the originator are issued. If the called party responds, the process is transferred to step 6c as shown in FIG. 6, and the call is controlled. If the call end is monitored by monitoring the end of the call in step 6d, the line is opened by step 6e. To return to the standby state.

On the other hand, when the caller releases the caller, the control circuit 6 shifts to 5K to open the line and return to the standby state.

On the other hand, if the call originating operator operates the random subscriber selection key 72 after checking the dial tone, the control circuit 6 determines that the call originating is automatically performed in step 5e, and then proceeds to step 5m. In addition to inputting the key code of the subscriber selection key 72, the priority n of the line is set to 1 in step 5n.

Thus, in step 5o, the phone number of the line with the highest priority is read out by one digit from the area corresponding to the key code of the subscriber selection key 72 in the RAM 8, and the dial according to the phone number in step 5p. Not only does it generate a pulse or DTMF signal and send it out to the subscriber line 1, but also turns on the indicator 18 at step 5q to notify the outgoing call operator. Thus, if the transmission of the whole-digital dial signal is terminated, the transmission end of the dial signal is detected in step 5r, and then the process proceeds to steps 6a and 6b shown in FIG. Done.

For example, if the caller's priority line is in the standby state and the communication party is called, and the subscriber of the communication party responds to the call, the control circuit 6 transfers the call control in step 6c. After that, a call can be established between both communication terminals.

On the other hand, if the line having the first priority is in a call, the busy tone is transmitted from the exchange to the originating caller terminal. If so, the control circuit 6 detects the arrival of the busy tone BT from the detection signal of the signal detector B and proceeds to step 6f, so that the line is first opened.

Therefore, after checking the elapse of a predetermined time required for the return operation of the exchange in step 6g, the priority n is increased in step 6h and set to n + 1. Then, in step 6i, the priority n becomes RAM (8). It is determined whether or not the number of lines registered in the " If, for example, the number of communication counterparts registered in the RMA 8 was three lines, the priority is n = 2, and the process returns to step 5o shown in FIG. 5, where the subscriber selection key 72 of the RAM 8 is returned. This time, the telephone number of the line with the second priority is read out from the area corresponding to). Whenever the telephone number is read out by one digit, the dial pulse or DTMF signal corresponding to the telephone number is transmitted to the subscriber line 1 in step 5p and the call out is displayed in step 5q.

Therefore, the outgoing call output according to the automatic dial call is made to the line with the second priority.

Thus, if this line is in the idle state, a call is made to the other terminal from the exchange, and if the subscriber of the other terminal responds to the call, the call is transferred to the call state.

In the same manner, when the outgoing call line is busy, the telephone number of the line is selected by lowering the priority n by one, and the transmission of the dial signal according to the call number is controlled.

If the 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, the process goes from step 6i to step 5n. The priority (n) is set to 1, and accordingly, the automatic dial transmission operation is repeated in order from the first priority line.

As described above, in the present embodiment, when a caller who calls a plurality of lines is called out according to an automatic dial call, the line whose priority is after the second place is automatically when the line whose priority is first is busy. Since the automatic dialing is selected sequentially, the call originating operator stores the telephone numbers of the lines owned by the desired communication counterparts in advance in the RAM 8, respectively. Auto dialing for each line can be done sequentially and selectively as long as you operate. Therefore, the operability of the call originating operator is greatly improved, and the accurate outgoing call is reduced as the occurrence of the input piece is reduced as compared with the conventional communication terminal device, which requires that a telephone number be input by manual input at that time. Can be done.

In addition, since the telephone numbers of a plurality of lines owned by the communication partner are stored in a storage area corresponding to each subscriber selection key 72 in the RAM 8, the number corresponding to the number of keys of the subscriber selection key 72 is stored. It is possible to automatically register a communication partner, so that a plurality of communication partners can make outgoing calls by automatic dialing.

The present invention is not limited to the above embodiment. For example, in the above embodiment, when each line owned by the communication partner was busy, the call was repeatedly made in the order of high priority. The call origination operation may be stopped at the time when it is determined that the call is in progress, or the call origination may be automatically performed from the line having the first priority after a certain time. In addition, an indicator capable of displaying a message, such as a liquid crystal display, may be provided so that the indicator may display the name of the other party and the line name of the outgoing call originator. It may be read out and displayed according to the instruction of the call origination operator.

Otherwise, the number of telephone numbers or lines of the dial information storage device registered in the RAM, the configuration of the memory information, the configuration of the line state determination means, the control contents and control procedures of the first and second dial transmission means, the type of communication terminal device (facsimile machine) It is also possible to carry out various modifications within the scope not departing from the gist of the present invention.

As described above, according to the present invention, a dial information storage device which stores dial number information of a plurality of lines owned by the communication partner for each desired communication partner, and a signal derived from the communication network after the dial signal is sent out. Line state determining means for determining whether a line on the called party is in communication; a first dial sending means and a second dial sending means, when the call request is issued to the communication partner by the first dial sending means. Not only does it transmit the corresponding dial signal from the dial information storage device to the communication network, but also the second of the plurality of dial number information corresponding to the communication partner from the dial information storage device after the dial signal is sent by the first dial sending means. Selectively read dial number information to correspond to the dial number information. By sending the dial signal to the communication network, not only does not limit the number of communication partners that can register automatic dial transmission, but also can automatically dial a plurality of lines owned by the communication partner. Not only can the call operator improve the operability, but also can provide a communication terminal apparatus capable of making outgoing calls according to automatic dialing for many communication partners.
