Abstract

PURPOSE:To store a dial number in a dial number storing and retransmitting part during a speech, and to dial a callee number consecutively by providing a channel and a means to separate the dial number storing and retransmitting part. CONSTITUTION:It is decided to be a speaking state by counting mean connection time by a microprocessor 6 after the transmission of the dial number, and the dial number storage and transmission circuit 5 is separated from the channel, and during the speech, the dial numerals of a next destination party are stored in the dial number storage and retransmission circuit 5. After the speech is finished, when the on-hook of the subscriber is detected by a call-answer- restoration detection circuit 4, the dial number storage and retransmission circuit 5 is connected again to the channel. Thus, at the time of retransmission, the PB signal of the dial numerals of the next destination party, stored temporarily in the dial number storage and retransmission circuit 5 is transmitted automatically to an exchange side.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a telephone dial number storage and retransmission system [Prior art] In the conventional dial number storage and retransmission system, a caller dials a called party once. When a call is made, the dialed number is stored, and when the called party is busy, unanswered, or absent, and the called party wants to dial again, the stored dialed number is retransmitted to connect to the called party.

[Problem that the invention seeks to solve]

In the conventional dialed number storage and retransmission method described above, when entering a call with a called party and entering the number of the next called party to be connected, a selection signal is sent to the communication path between the calling party and the called party. This has the disadvantage that the call is interrupted and it takes time to dial the number of the called party consecutively.

SUMMARY OF THE INVENTION An object of the present invention is to provide a dial number storage and retransmission system that solves the above-mentioned problems.

[Means for solving problems]

The present invention stores the dialed number in the telephone when dialing a telephone number, and in a telephone equipped with a dialed number storage and retransmission function that retransmits the dialed number by pressing a button, the communication route and the dialed number storage and retransmission section are used during a call. This is a dialed number storage and retransmission system for a telephone set, characterized in that the telephone set has a means for disconnecting the dialed number and stores the dialed number in the dialed number storage and resending section without interrupting the call during a call.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an example of the configuration of the dial number storage and retransmission system of the present invention. In the figure, 1 is a key telephone, 2
is a PB handset, and 3 is a communication path circuit. 4 is a call origination, response, and recovery detection circuit; 5 is a dial number storage and retransmission circuit;
6 is a microprocessor, and 7a and 7b are data buses. 8 is a dial digit analysis circuit, 9 is a program storage circuit, 10 is a display control circuit, 11 is a power supply circuit, 1
2 is a numeric keypad, and 13 is a display.

At the calling party, the subscriber's off-hook is on PB handset 2.
, the communication path circuit 3, is detected by the call origination, response, and recovery detection circuit 4, and is input to the microprocessor 6 via the data bus 7a. When the exchange detects a call, it sends a dial tone (DT) to the key telephone 1. Since the subscriber inputs the dialed digits of the other party from the numeric keypad 12 after hearing the dial tone (DT), the dialed digit analysis circuit 8 that analyzes the digits on the numeric keypad analyzes the dialed digits and then inputs the dialed digits via the data bus 7a. Data is sent to the microprocessor 6. The pressed dial digits are sent moment by moment to the program storage circuit 9 and the dial number storage and retransmission circuit 5, and are sent via the display control circuit 10.
The dialed numbers are displayed on the display 13.

The dialed number storage and retransmission circuit 5 temporarily stores the dialed numbers and sends the PB multiplication signal of the dialed numbers to the switching equipment side at any time. After sending out the dialed digits, the microprocessor 6 counts 10 to 15 seconds as an average connection time and determines that a call is in progress. Next, the dialed number storage and retransmission circuit 5 is disconnected from the communication path. Thereby, the dialed number of the next destination can be stored in the dialed number storage and retransmission circuit 5 during the call.

After the call ends, call and answer the subscriber's on-hook call.

When detected by the restoration detection circuit 4, the dialed number storage and retransmission circuit 5 is connected to the communication path again.

Next, when the subscriber uses the resend function of the key telephone 1, he presses the call button, then presses the resend button, and the next destination temporarily stored in the dialed number storage and resend circuit 5 is pressed. The signal multiplied by pB of the dialed number is automatically sent to the switching equipment side. The subsequent operations are the same as for making a normal call. There is also a power supply circuit 11 for supplying power to all these circuits.

FIG. 2 shows an operational flowchart of the dialed number storage and retransmission system of the telephone according to the present invention.

〔Effect of the invention〕

As explained above, the present invention has a means for separating the dialed number storage and retransmission unit from the call path, so that the dialed number is stored in the dialed number storage and retransmission unit during a call, and
Immediately after the end of a call, the dialed number can be sent from the dialed number storage and retransmission unit, which has the effect of continuously dialing the called party's number.
