Abstract

PURPOSE:To attain redialing at the next call even when dialing is tried after a telephone line is closed by applying redialing registration to dial information only as called party selection information among various sets of dial information. CONSTITUTION:When a trunk line 3 is a calling trunk line and dial information from a key telephone set 2 is set before a called party responds to, that is, when a CPU 107 receives the dial information from the key telephone set 2, while a trunk line incoming detection circuit 101 does not send trunk line incoming information and a trunk line response detection circuit 102 does not send called party reply information, since the dial information is the dial information to select a called party, the CPU 107 applies redial registration processing to provide the dial information into a RAM 109 through redial registration thereby completing the processing for 1 digit of the dial information. The above operations are applied to the dial information of all digits set from the key telephone set 2 and the redial registration is applied only to the dial information for called party selection.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a so-called redial service in which previously sent dial information is sent out again to a telephone line by a one-touch operation on a telephone.

(Prior art) For example, in a button stain filling device, dial information sent from a button telephone to a telephone line, such as a central office line, is sent to a main device or a mailbox in the button telephone until other dial information is sent in the next call. A so-called redial method is well known in which the user memorizes the same dial information as last time, and when he wants to send out the same dial information as last time, he presses the redial information button and sends out the same dial information as last time based on the stored information of the above-mentioned message. be.

By the way, in recent years, due to the practical use of instantaneous international calls or banking services using telephone lines, there are many opportunities to send out various dial information by dialing after the telephone line has been established with the called party. It is becoming. In such a case, in the conventional redial system, all dial information (the called party number and the number sent after the call line is closed) is generally stored in the retirement information storage erise of the system.

(Problems to be Solved by the Invention) According to the above-mentioned conventional redial system, if you accessed a bank's computer during a previous call to receive banking services, and you want to access the same bank's computer again, you can do so by redialing. In addition to the called party's dialing information (bank number), number information for banking services is also sent, resulting in incorrect connection or incorrect access to the computer. Therefore, if you perform a dialing operation after the telephone line was closed during the previous call, you will not be able to receive the redial service.

The present invention is proposed to solve the above-mentioned conventional problems, and aims to provide a redial system that allows redialing the next time a call is made even if a dialing operation is performed after the telephone line has been closed. purpose.

(Means for Solving the Problems) For the above purpose, the present invention provides that when a telephone line is captured by a telephone, the telephone line is captured for an outgoing call, and the called party This system detects that the called party has not yet responded, stores only the dial information sent in this state, and sends only the called party dial information again at the time of requisition.

) 109 and button telephone 2 and the CPU 10
A data transmitting/receiving circuit 110 that relays transmission and reception of various control data is connected to the terminal 7.

Further, although not shown in the figure, the button telephone 2 is equipped with a tire report port and a retirement port related to the present invention.

Although FIG. 1 shows an example in which the present invention is implemented in a button telephone device, even if it is a so-called stand-alone telephone that is directly connected to the central office line 3, a C! The present invention can be implemented by using PU, RAM, etc.

(Operation of the embodiment) FIG. 2 is a flow chart showing the operation of the embodiment of the present invention. Incidentally, FIG. 2 shows the processing of one digit of dial information.

When a line selection button (not shown; hereinafter, items without symbols indicate those not shown) is pressed on the button telephone 2, the CPU 107 of the main device 1 transmits the data to the button telephone 2 via the data transmission/reception circuit 110. The central office line connection circuit 104 operates the central office line connection circuit 104 to connect the central office line 3 and the button telephone set 2 .

Here, when the dial information button is pressed on the button telephone 2, the dial data is sent to the CPU via the data transmission/reception circuit 110.
107, the CPU 107 drives the FB signal generation circuit 105 or the DP signal generation circuit 106, and sends out dial information corresponding to the pressed dial button from the cell information output circuit 103.

The above FB signal generation circuit 110 or DP signal generation circuit 10
Although not shown in FIG. 2, the selection of No. 6 is determined as follows. That is, if the acquisition of the station line 3 by the line selection button is for calling and the station line 3 is a DP line, the DP signal generation circuit 106 is selected; line, and when station line 3 is a PB line)
PB signal generation circuit 105 is selected.

At the same time as sending the dial information corresponding to the pressed dial button, the CPU 107 determines whether the captured office line 3 is the incoming office line or the originating office line, that is, whether the captured office line 3 is the incoming office line or the originating office line. It is detected whether the acquisition is for responding or for making a call using central office line 3, and if it is the terminating central office line, that is, C! When the CPU 107 receives dialing information from the button telephone 2 via the data transmission/reception circuit 110 while the CPU 107 receives the central office line incoming information (calling signal) from the central office line incoming detection circuit 101, the CPU 107 The processing for one digit of the dial information is completed without redialing the dial information. Further, if the office line 3 is a calling office line, it is determined whether the dial information from the key telephone 2 was sent before or after the called party answered. That is, when the called party answers, the called party response information is normally sent to the office line 3 by polarity reversal, so this is detected by the office line response detection circuit 102, and the CPU 107 reads the response information. If the dial information is sent from the button telephone 2 after that, the CPU 107 determines that the dial information was sent after the called party answered, and does not register the dial information as redial. Processing for one digit of dial information is completed.

In both of the above two cases, end-to-end communication is performed using dial information after the telephone line is closed (for example, communication to interact with a bank computer), and both of these dial information are registered as redial information. Not done.

Next, if the office line 3 is the originating office line and the dialing information from the button telephone 2 is not sent before the called party answers, in other words, the office line incoming call detection circuit 101 does not send out the office line incoming information.
In addition, if the CPU 107 receives dialing information from the key telephone 2 in a state where the central office line response detection circuit 102 does not send out called party response information, the said dial information is the dial information for selecting the called party. (3P
U 1.07 performs redial registration processing and stores RAM
109, and the processing for one digit of the dial information is completed. Note that the redial registration process itself is performed using a conventionally known method.

The above operations are performed for all digits of dial information sent from the key telephone 2, and redial registration is performed only for the dial information made for selecting the called party. Furthermore, when new dialing information to be registered for redialing is sent, the previously registered redialing information is erased when processing the first digit, and this process itself has not been performed before. Since this can be carried out using a known method, it will not be described in detail.

If you want to make a call to central office line 3 using the redial information after redial registration, press the button.If you capture central office line 3 (not limited to the central office line used at the time of redial registration) with 7It handset 2 and press the redial button, the CPU 107 will send data to Transceiver circuit 11
The redial information is received from the key telephone 2 via 0, reads out the dial information stored in the RAM 109, and drives the FB signal generation circuit 105 or the DP signal generation circuit 106 according to the cell information based on the redial information. Dial information for selecting a called party is sent from dial information output circuit 103 to line 3.

Note that the PB signal generation circuit 105 or the DP signal generation circuit 10
The operation for selecting one of 6 is the same as the normal dial operation.

The present invention can also be implemented for speed dialing. That is, when a speed dial is made, a program for redial registration processing may be constructed so as to perform processing such as translating the speed dial information into normal dial information and storing it in the RAM 109.

(Effects of the Invention) As described above in detail, the present invention is configured such that among the various dial information sent from the telephone, only the dial information as called party selection information is registered as redial. The present invention has various advantages, such as being able to provide a redial service even if the telephone is equipped with an end-to-end communication function by dialing necessary for banking services, etc., and eliminating the possibility of incorrect connection due to retirement. The effect is extremely remarkable.
